What are the classifications of building formwork? What are the classifications of formwork projects

Building formwork refers to the formwork used for the construction of concrete structures. According to the different materials and construction methods, building formwork can be divided into many types. Here are some common building template classifications:

1.Wooden formwork: Wooden formwork is one of the earliest types of building formwork, made of wood, and is often used in the construction of the first layer of concrete structures. Because wooden formwork is perishable, it has now been replaced by other types of formwork;

2.Steel formwork: Steel formwork is a formwork made of steel, which has the advantages of high strength, light weight and good durability. Steel formwork is suitable for large-scale concrete structure engineering, such as high-rise buildings, bridges, etc.;

3.Aluminum alloy formwork: Aluminum alloy formwork is a high-strength, lightweight formwork made of aluminum alloy material. Aluminum alloy formwork is suitable for concrete structure construction, especially in high-rise buildings;

4.Plastic formwork: Plastic formwork is a template made of plastic material, which has the advantages of lightweight, durable, and low cost. Plastic formwork is suitable for concrete structure construction, especially in small engineering and concrete component construction;

5.Composite Template: A composite template is a reusable template that consists of multiple components that can be disassembled and assembled. The composite formwork is suitable for the construction of concrete structures, especially for large-scale projects that need to be used many times;

6.Jump formwork: Jump formwork is a kind of formwork used for the construction of concrete structures, usually used for pouring the first layer of concrete. The jumping formwork is characterized by being lifted and rotated, making concrete pouring more convenient.

The above are some common building formwork classifications, different formwork types are suitable for different concrete structure construction scenarios, and the specific choice should be decided according to actual needs.

1) Classification according to the material Formwork is divided into wood formwork, steel wood formwork, steel formwork, steel bamboo formwork, and plywood according to the different materials used.

Formwork, plastic formwork, FRP formwork, aluminum alloy formwork, etc.

1. The tree species of wood formwork can be selected according to the actual situation of each region, and most of them are pine.

and fir wood. Due to the wooden formwork wood.

The consumption is large, the reuse rate is low, in order to save wood, in the cast-in-place reinforced concrete structure.

Wooden formwork should be used as little or no as possible. The steel-wood formwork is a stereotyped template with angle steel as the frame and wooden planks as the panel, which has the advantage of making full use of short wood and can be used for many turnovers;

2. The plywood template is a stereotyped template with plywood as the panel and angle steel as the frame. The plywood is used as the panel, which overcomes the shortcomings of the unequal directionality of the wood, and has good stress performance. This kind of formwork has the advantages of high strength, small dead weight, no warping, no cracking, large plate width and few joints.

The steel bamboo formwork is a shaped board with angle steel as the frame and bamboo plywood as the panel. This kind of template has large stiffness, is not easy to deform, is light in weight and easy to operate;

3. The steel formwork is generally made into a stereotyped formwork, assembled into various shapes and sizes with connecting components, suitable for a variety of structural forms, and widely used in the construction of cast-in-place reinforced concrete structures. The steel formwork has a large amount of investment at one time, but the turnover rate is high, and attention should be paid to the storage and maintenance in the process of use, and the rust should be prevented to prolong the service life of the steel formwork;

4. Plastic formwork, FRP formwork and aluminum alloy formwork have the characteristics of light weight, high rigidity, convenient assembly and high turnover rate, but due to the high cost, they have not been widely used in construction.

2) Classification according to the type of structure Various cast-in-place reinforced concrete structural components, due to their different shapes, sizes, and structures, the structure and assembly methods of the formwork are also different, forming their own characteristics. According to the type of structure formwork, it is divided into: foundation formwork, column formwork, beam formwork, floor formwork, stair formwork, wall formwork, shell formwork, chimney formwork and so on.

3) Classification according to construction methods.

1. On-site assembly and disassembly formwork at the construction site.

The formwork is assembled on site according to the structural shape, size and spatial location of the design requirements, when the concrete reaches the demoulding strength.

After dismantling the formwork. On-site assembly and disassembly formwork mostly uses shaped formwork and tool-type support;

2. Fixed formwork Formwork for making prefabricated components. According to the shape and size of the component, the template is made on site or in a prefabricated factory. All kinds of tire molds (soil tire molds, brick tire molds, concrete tire molds) are fixed templates;

3. Mobile formwork With the pouring of concrete, the formwork can move in the vertical or horizontal direction, which is called mobile.

At present, there are two main categories of advanced wall formwork systems abroad: the first type is the frameless formwork system, which is made of wood-beams or section steel, and the panels are solid wood formwork or plywood building formwork. This kind of template is low, flexible to use, and can be assembled into a formwork structure of various shapes, especially the structure with a more complex shape, and is suitable for a wide range of projects

The second type is the framed plywood formwork system, in which the frame and rib of the small steel-framed plywood formwork are hot-rolled flat steel, and the plate thickness is generally 6ram; The frame and rib of the light steel frame plywood formwork are cold-formed steel, or the frame is a hollow steel frame, and the rib is cold-formed steel; The frame and ribs of the heavy-duty steel frame plywood formwork are hollow steel frames. The characteristics of these templates are that the strength and rigidity of the steel frame are very large, and when the template is assembled, there is no need to attach the vertical and horizontal flutes, and only the ribs of the two templates need to be clamped and fixed with a fixture, so the assembly and disassembly speed is relatively fast, and the labor and material saving are very convenient.

1. Deep foundation pit engineering

According to the nature of the material, it can be divided into building formwork, building wood plywood, laminated board, multi-layer board, 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 building formwork structure used in the construction of cast-in-place concrete structure engineering is mainly composed of three parts: panel, support structure and connector. The panel is a load-bearing plate that is in direct contact with the freshly poured concrete; The supporting structure is a temporary structure that supports the panel, concrete and construction load, ensuring that the building formwork structure is firmly combined and not deformed or damaged; A connector is an accessory that connects the panel with the support structure as a whole.

When the concrete of the bottom plate or roof is poured and has a certain strength (i.e., it is not soft and has no traces when pressed by hand, the master can start to measure the axis. According to the axis position, the wall column section position dimension line and the template 500 control line are released to facilitate the installation and correction of the beam template.

When the concrete is poured and the formwork is removed, the 500mm elevation control line of the floor is introduced, and the control line of the bottom of the slab is directly tested according to the 500mm line.

Firstly, the control line of the main axis of the building is guided according to the floor axis measuring hole, and the control line is taken as the starting point, each axis is drawn out, and the inner line, the edge line and the outer control line of the template are ejected with ink lines according to the axis and the construction drawing, and the three lines must be in place before construction, so as to facilitate the installation and correction of the template.

There are many ways to classify formwork, which are usually classified in the following ways: (1) According to different materials, it can be divided into wood formwork, steel formwork, plywood formwork, steel-wood formwork, plastic formwork, steel and bamboo mold concrete structure construction effect display 39 boards, aluminum alloy formwork, etc.

2) According to different structural types, it can be divided into foundation formwork, column formwork, floor formwork, wall formwork, shell formwork and chimney formwork.

3) According to the different forms and construction techniques of the formwork, it can be divided into integral formwork, shaping formwork, tool-type formwork, sliding template, tire mold, etc.

4) According to different construction methods, it can be divided into on-site assembly and disassembly formwork, fixed formwork and mobile formwork.

5) According to the different functions of the formwork, it can be divided into ordinary forming formwork and fair-faced concrete.

Forming formwork, decorative concrete forming formwork with decorative stripes and patterns, permanent formwork as a structural component and formwork with internal and external insulation layers that are not dismantled.

The types of formwork commonly used in construction projects are as follows:

1.Wood formwork: Wood formwork is the more common and traditional building formwork, usually made of wood, such as plywood, solid wood boards, etc. Wood formwork has good bearing capacity and adaptability, and is suitable for various types of building structures.
