What are the commonly used building formwork sizes?

The general construction of building formwork is more used according to the size and thickness of the classification, each classification is as follows:

Classification by size:

4*8 feet slab (1220*2440mm).

3*6 feet small board (1830*915mm).

Classified by regular thickness:

7-layer board (10mm).

8-layer board (8 layers 11mm thin, 12mm thick 8 layers).

9-layer board (thin 9-layer 13mm, medium 9-layer, thick 9-layer 14mm) 10-layer board (

There are two most commonly used types of rules:

1.915mm*1830mm thickness: 14mm-18mm;

2.1220mm*2440mm thickness: 16mm-20mm.

Timber formwork duIt consists of a panel and a support system, the board is the part that makes the concrete form; The support system is the part of the structure that stabilizes the position of the panels and bears the upper loads. The quality of the formwork is related to the quality of the concrete project, and the key is that the size is accurate, the assembly is firm, the joint is tight, and the assembly and disassembly are convenient. The appropriate form of template should be selected according to the form and characteristics of the structure in order to achieve good technical and economic results.

Formwork and support systems for large-scale and special projects should be calculated to check their stiffness, strength, stability and ability to withstand side pressure.

Wood formwork material requirements.

1. The foundation template is made of pine plank, poplar plank, eucalyptus plank, and the thickness of the side plate of the ground beam is 20mm.

2. The bottom template of the main beam is made of pine plank, the thickness of the bottom template is 40mm, and the thickness of the column template and floor template is 12mm.

3. The support system is made of fir logs, the diameter of the small head is not less than 70mm, and the size of the small square wood is 400 500mm, of which the bottom support system is supported by steel pipes.

4. The wood formwork and support system shall not be brittle, seriously twisted and deformed by moisture.

Wood molds are generally used for non-special buildings, and there are two specifications of wood formwork: ,, and the thickness is between 11-18mm.

There are still many sizes and specifications of building templates, and it is widely used in life. There are two kinds of specifications, one is rice, and the other is rice. Its thickness is also large and small, such as some centimeters, some centimeters or centimeters.

If you choose a meter, the thickness is slightly larger, basically between centimeters.

There is also a kind of laminated building formwork, which is slightly thicker, commonly used centimeters or 2 centimeters, and some centimeters and so on. Different building formwork uses different times. If you choose a meter and a centimeter, you can use it up to 8 times.

If it is centimeter thick, it can be used up to 10 times.

Building formwork structure

Now a brief introduction of the combined steel formwork is as follows: the combined steel formwork is a new type of formwork of "replacing wood with steel" in modern formwork technology, which has the advantages of strong versatility, convenient assembly and disassembly, and many turnover times, and uses it to carry out cast-in-situ reinforced concrete structure.

Construction, can be assembled into beams, columns, walls, floors according to the design requirements of the large formwork in advance, the overall hoisting in place, can also use the bulk dismantling method.

The building formwork is a concrete pouring formwork and support, which can be divided into building formwork, building wood plywood, laminated board, and multi-layer board according to the nature of the material.

Double-sided lamination, double-sided laminated building formwork, etc. According to the construction process conditions, the building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jumping formwork, etc.

The common specifications of building wood formwork are two types: meters * meters and meters * meters. The thickness of the building wood formwork is centimeters, centimeters, centimeters, etc., in addition, there is a specification of meters * meters, the thickness is centimeters, centimeters, centimeters, and so on.

The building wood formwork m * m black laminated board cm thick can be used 8 times. Centimeter-thick black laminates can be used 10 times, and centimeter-thick black laminates can be used 12 times. Centimeter thick building red laminated template can be used about 15 times for centimeter thick iris.

The plate can be used about 18 times.

The two most commonly used specifications are:

mm*1830mm thickness: 14mm-18mm, mm*2440mm, thickness: 16mm-20mm.

The size of the glued formwork used for the building formwork is usually about 1200mm in width, about 2400mm in length, and about 12 18mm in thickness. The common specifications of glued formwork for building formwork in China are *915*15, 2440*1220*18.

The size and specifications of the building formwork are mainly ,,, and divided according to the thickness, there are ,,, and so on. If the selected building formwork is, then its thickness needs to be slightly larger, generally in order to meet daily use.

Want to choose a building template, but don't know which one is excellent? Recommend the earth wood. Langfang Dadi Wood Industry Co., Ltd., founded on November 29, 2002, is located in China's plywood production base - Zuogezhuang, Langfang, Hebei Province, China's early professional production of Qingshui building formwork enterprises.

The company is adjacent to Beijing and Tianjin, north of Jinbao Expressway, located in the center of Beijing, Tianjin and Baozhou Triangle, and the geographical location is very superior. The company now has two production bases, covering an area of more than 30,000 square meters, more than 800 employees, including 68 professional and technical management personnel, total assets of more than 120 million yuan, and now has 80 sets of advanced equipment at home and abroad. The company has an annual production of more than 20 million cubic meters of laminated boards of various specifications, with an annual output value of 100 million yuan, and has passed ISO9001:

2008 international quality system certification, the product has been tested by the National Institute of Quality Supervision and Inspection to meet the GB T17656-2008 "Plywood Standard for Concrete", of which the "Dadi" brand clear water formwork, after 23 processes, the use of two molding processes, layers of phenolic glue, high recycling times, trusted by customers. <>
