Menghitung Volume Besi per-m3 beton bertulang

Dalam Sebuah kegiatan pembangunan perumahan salah satu hal yang paling sulit dilakukan oleh mereka yang awam adalah cara menghitung volume material yang dibutuhkan secara tepat dan efisien.

Pada kesempatan kali ini saya mencoba membahas mengenai perhitungan volume besi tulangan pada tiap m3 beton ( satuan yang biasa digunakan untuk volume beton bertulang adalah m3 ).

Contoh kasus.

Dimensi beton 15/20 cm dengan rincian penulangan :

• tulangan 4 diameter 12 ( tulangan utama ) 
• tulangan diameter 6 jarak 20 cm ( tulangan beugel )

Secara prinsip kita harus bisa menterjemahkan volume 1 m3 beton dengan ukuran 15/20 cm.

• 1 m3 beton = 1/(0.15x0.2) m ( panjang beton 1 m3, dimensi 15/20 ) = 33 ,33 m dibulatkan 34 m
• Asumsi yang digunakan panjang 1 lonjor besi = 12 m

panjang besi tulangan yang dibutuhkan :
Besi tulangan Utama

panjang Besi diameter 12 = 4 bh x ( 34 m - 0,02 m ( selimut beton )) = 4 x 33,98 = 135,92 m
panjang besi dalam lonjor = 135,92/12 = 11,33 ljr
berat besi 12 per-lonjor = 0,074x12x12 = 10,66 kg/ljr( bisa dengan menggunakan tabel besi tulangan )
(reff. perhitungan praktis berat besi per-lonjor = analisa harga satuan dan rencana anggaran biaya )
jumlah berat besi 12 dalam 1 m3 ukuran 15/20 = 10,66 kg/ljr x 11,33 ljr = 120,74 kg

Besi tulangan beugel

jumlah beugel dengan jarak 20 cm sepanjang 34 m beton bertulang = 34 m / 0.2 m = 170 bh beugel
Perhitungan panjang beugel pada beton dimensi 15/20.
selimut beton = 1,5 cm ( satu sisi ) = 3 cm ( dua sisi )
panjang 1 beugel [ (15-1,5x2)x2 sisi + (20-1,5x2)x2 sisi ] = 12x2 + 17x2 = 24 + 34 = 58 cm
panjang pembengkokan tulangan 5 cm x 2 = 10 cm
Panjang total 1 beugel = 58 + 10 = 68 cm = 0,68 m
berat besi 6 per-lonjor = 0,074x6x6 = 2,66 kg/ljr ( bisa dengan menggunakan tabel besi tulangan )
jumlah panjang total = 0,68 m x 170 bh =  115,6 m/12  = 9,63 ljr 
jumlah berat beugel total = 9,63 ljr x 2,66 kg/ljr = 25,63 kg

Jumlah berat besi total dalam 1 m3 beton ukuran 15/20 = 120,74 + 25,63 = 146,37 kg/m3

Ini adalah contoh kasus sederhana yang mungkin bisa digunakan untuk memahami perhitungan kg besi dalam 1 m3 beton bertulang.

A Creative Kitchen Renovation in the Craftsman Style

The original kitchen was designed as a separate space that did not lend itself to interaction with the adjoining spaces.  There were three single openings that led to the dining room on the west, to the family room on the south and to the laundry and garage at the north.  A priority for the owners was to have more openness between the kitchen and adjacent spaces without sacrificing large amounts of cabinet and counter space. 




Existing Kitchen Floor Plan

 

Existing North Wall

Existing South Wall

Maintaining some visual privacy in the kitchen to hide the working areas was also necessary. The owners also wanted to preserve the breakfast table area and bay window, redo the cabinets and counters, and replace the existing appliances in a way that appeared to be original to the house.

 

New kitchen floor plan


  



The design solution that worked best included changes to the plan that would increase the openings between the kitchen, dining, and family rooms while still providing visual separation through the use of new pocket doors and a raised bar design which repeated at the island sink.  By eliminating the 'L-shaped' leg where the range and microwave once stood, we were able to center the opening to the dining room and add a pair of glass pocket doors.

These doors could be left open to allow for full access or closed when more privacy was needed.  The range was replaced with  a cooktop which was moved to the north wall along with a set of wall ovens.  The sink and dishwasher was relocated to the enlarged island with a raised ledge that shields the sink from view of the family room.  The refrigerator was replaced with a counter depth refrigerator and was designed with a built-in appearance.  A larger opening was added between the kitchen and family room on the south wall along with a new bar with raised ledge.  The pantry cabinet was replaced with a new cabinet with pull-out shelves and better designed storage.  The desk was removed to allow for a wider opening leading to the laundry, garage, and rear yard access on the north wall and a full height cabinet was added to house school and home office supplies.

Storage for Spices and Oils



The revised layout achieved everything the owner wanted by preserving ample counter and cabinet space, improving the access and flow between spaces and updating the kitchen's appearance with rich earth tones and the simplistic beauty of craftsman style cabinets.  The cabinet maker, Joe Davenport, worked with the homeowner to produce unique details and hidden storage areas for spices, oils, and utensils.

The new design fulfills all the home owner's wishes and desires in a way they never imagined possible.  The seamless integration of the new kitchen with the existing family room and dining room makes it impossible to imagine this house with anything other than the design that is here now.  The warmth and beauty of the wood, tile, and granite work harmoniously to add character and charm to the heart of this home and the renovations have made entertaining as well as everyday use a pleasure and a joy.





Kitchen Trends: Common Kitchen Configurations

Kitchens are as diverse and different as the people who own them; however, most kitchens tend to fall into one of seven basic categories.  The seven most common kitchen configurations include Single Wall, Galley, L-Shaped, L-Shaped with an Island, U-Shaped, U-Shaped with an Island, and G-shaped.  Each layout has unique advantages and disadvantages, but they can all be well suited for particular applications.

Single Wall

Single Wall: While this layout is most efficient in terms of the amount of space needed, it is least efficient in terms of use. All of the appliances must be located along the same wall, requiring the cook to shift back and forth between them while staring at a wall the entire time. It is not ideal for entertaining since the cook’s back is turned towards guests and family members and it is difficult for more than one person to use this kitchen at a time. This layout does work; however, in cases where space is highly restricted or where the owner does not do a lot of cooking or entertaining. It also works best if the sink is located in the middle with the stove and refrigerator located at each end. 



Galley with Island



Galley



Galley: This layout is much easier to use and can still be an efficient use of space. The Galley kitchen has two rows of cabinets and appliances located on parallel walls. There should be at least four feet of open floor area between the two rows of cabinets for kitchens that are used by a single cook most of the time. For kitchens where multiple people prepare meals at the same time, it is more desirable to allow five to six feet of open floor space.  This layout is not ideal for entertaining since it does not allow for guests to interact with the cook, but slight modifications to this traditional layout can help solve that problem. By removing one of the walls along the cabinets, you can create an island which is open to an adjacent space and provides an area for seating and better entertaining potential. This change; however, does reduce the amount of upper cabinet storage by half.

 

L-Shaped

L-Shape with Peninsula

L-Shaped: This layout is the result of two rows of cabinets and appliances located on perpendicular walls. There is more travel distance required between appliances in this layout compared to the Galley shape, but it does allow an open floor area suitable for a small table and chairs. Many eat-in kitchens utilize the L-shape. This layout is also easier to use for multiple cooks. In this layout one wall can be removed creating a peninsula for better entertaining and more seating.



Modified L-Shaped with Island



L-Shaped with Island



L-Shaped with Island: As the name suggests, this layout utilizes the L-shape described above with the addition of an island to create a more efficient use of space. The island helps to add the efficiency of a Galley style kitchen while keeping the second leg of the L-shape. This provides additional counter, cabinet, and seating potential. The island should be placed a minimum of 3’-0” away from any wall or cabinet. This can get tight, so I would recommend a clearance of at least 3’-6” from a cabinet or wall and a minimum of 4’-0” if the island is adjacent to the refrigerator or ovens. Again, if the space is meant to be used by more than one cook at a time, allow for wider clearances.



U-Shaped

 U-Shaped: The U-shaped kitchen is very common and utilizes three walls which work nicely when the three major appliances are each placed on their own wall. Separating the sink, refrigerator, and stove creates independent zones for each appliance; however, a compact U-shape integrates them all together. The floor area between the two parallel cabinets needs to be at least 5’-0” and should be wider for multiple cook kitchens. This layout can be troublesome for multiple cooks and for entertaining since guests tend to gravitate into the central floor space or prop themselves against one of the cabinets which interferes with the cooking.



U-Shaped with Island



Modified U-Shaped with Island


U-Shaped with Island: This layout builds on the typical U-shape by adding an island space to serve all three legs of the kitchen. The island addition is ideal for kitchens with multiple cooks since it helps to create working zones for multiple users. The island also helps to keep guests out of the working area of the kitchen while still allowing the cook or cooks to be connected with guests. Adequate clearance around the island is key in this layout with a minimum of 3’-6” required and a recommended 4’-0” to 5’-0” for multiple cooks. The possibilities are nearly endless with this arrangement.

G-Shaped



Modified G-Shaped



G-Shaped: The G-shape is formed when a peninsula is added to a U-shaped kitchen. The peninsula provides additional counter and base cabinet storage space and allows for the addition of a bar area. The peninsula also helps to define the limits of the working kitchen from the entertaining areas; however, it can cause traffic flow problems since there is only one way in and one way out of the work area. This is not ideal for more than one cook. Like all the configurations listed here, the G-shape can be modified to allow better flow and more openness.

Although there are seven basic kitchen configurations, there are endless variations of each of these. A skilled designer can help you determine which configuration will work best for you by recognizing the limits imposed by existing walls and structure, by taking into consideration the owner’s budget, and by transforming your personal needs and desires into a uniquely suited design solution.
