Technical Field

[0001] The utility model relates to the technical field of building construction accessories, in particular to a frame used for making templates. Background Art

[0002] Building formwork is a temporary structure, which is made according to the design requirements to shape the concrete structure and components into the specified position and geometric dimensions, maintain its correct position, and bear the deadweight of the building formwork and the loads acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce the project cost.

[0003] In the prior art, wooden formworks are generally made of natural wood, which consumes a large amount of wood resources and may lead to waste of forest resources and environmental problems. Wooden formworks are easily eroded by moisture during use, while the manufacturing cost of aluminum-plastic frame formworks is relatively high. Compared with wooden formworks, the initial investment is relatively large. Due to the structural characteristics of aluminum-plastic frame formworks, they may not be suitable for some building structures of special shapes or sizes, and require additional customization, which increases the construction cost and cycle. Some manufacturers on the market have launched a one-time formed steel formwork product, but this type of one-time formed formwork has high material selection requirements, limited strength, poor bending effect, insufficient force on the frame, and cannot withstand multiple disassembly and assembly violent construction, which reduces the life of the formwork and increases the cost. Therefore, the overall strength defects of the steel formwork cannot be made, the service life is low, the precision control is difficult, the series of products are not easy to deform, and the manufacturing cost is high. In response to the above problems, a frame for making a formwork is now proposed. Utility Model Content

[0015] The diameter of the everted hole is 16.5 mm.

[0016] The utility model has the following beneficial effects:

[0017] In the utility model, the arc angle on the left side of the frame strip makes the part bear better force and have higher strength, and the workers will not prick their hands and prevent scratches when operating. The thickness of the template edge is increased by the L-shaped bend, which can make the template edge stronger and bear better force. When it is necessary to connect two frame strips, it is only necessary to pass the pin through the inside of the outward-turned hole to clamp it, thereby making the connection and installation of the steel template more convenient, quick and easy to operate.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3 As shown, an embodiment of the utility model is provided: a frame for making a template, including a frame strip 1, the material of the frame strip 1 is 700 high-strength steel, the 700 high-strength steel has good impact toughness, can maintain good impact toughness even at low temperatures, is suitable for various harsh environments, and has the characteristics of high strength, light weight, high yield strength and tensile strength, is suitable for manufacturing large steel structures, and is light in weight. The thickness of the frame strip 1 is 1.5-2mm, the height of the frame strip 1 is 63.5-65mm, and the head of the frame strip 1 is provided with an arc corner 2. The design of the arc corner 2 forms a closed loop. This design method firstly makes this part bear better force and has higher strength, and does not prick the hands of workers during operation to prevent scratches.

[0025] Reference Figure 1-Figure 3 As shown, a concave bend 3 is provided in the middle of the frame strip 1, the diameter of the hole 4 is 16.5mm, a concave bend 3 with a length of 28mm is provided in the middle, the bending depth of the concave bend 3 is 8mm, and a hole 4 with a diameter of 16.5mm is designed. The design of the hole 4 is that when two templates are spliced, the pins are passed through the two holes, and the pin pieces are driven in to clamp them. The hole 4 is turned outward by 2mm. A plurality of holes 4 are provided in the middle of the frame strip 1. The hole 4 can also have an ordinary round perforated version without turning outward. The purpose of this design is to allow the two frame strips 1 to be spliced ​​together. The 16mm diameter space formed by splicing the frame strips 1 is shortened by 4mm. The 16mm margin space can act as a spring, making it stronger and more stable, and realizing the soft connection of the pin. An L-shaped bend 5 is provided at the lower part of the frame strip 1. The bending depth of the L-shaped bend 5 is 8mm. The design of the L-shaped bend 5 is, firstly, to ensure the precise size of the frame strip 1 when processing it, and secondly, the bending increases the thickness of the edge of the template, which can make the edge of the template stronger and better stressed. The bending depth is 8mm.

[0026] Working principle: when the staff is using the frame strip 1, when making templates of different specifications, the frame strip 1 can be cut at will with hydraulic shears, and then the arc corner 2 on the left side of the frame strip 1 is designed to make the frame strip 1 have better force and higher strength, and it will not prick the hands of workers during operation to prevent scratches, and then when splicing two templates, the hole 4 opened on the outside of the frame strip 1 can be used to penetrate the inside with a pin to clamp it, making it firmer and more stable, and then the L-shaped bend 5 can be used to ensure its precise size when processing this steel section, and the L-shaped bend 5 also increases the thickness of the template edge, which can make the template edge stronger and better stressed, thereby making the manufacturing cost of the steel template low, deformation convenient, and deformation cost low. Note: some frame strips 1 also have designs other than the L-shaped bend 5.
