Technical Field

[0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It refers to the materials and equipment used, as well as the technical activities such as survey, design, construction, maintenance, and repair, as well as the objects of engineering construction.

[0003] The most common thing in civil engineering is the pouring of concrete. During the pouring of concrete, it is necessary to shape it through formwork. For example, the concrete support column in a house building is now shaped by the formwork on the outside, and then the steel bars are assumed inside, and finally the concrete is poured. In order to prevent the lateral tension of the concrete from stretching the formwork during the concrete pouring, the outside of the formwork needs to be reinforced. The current common way is to reinforce it with four support rods, and the adjacent support rods are tied together with wire to form a hoop. However, this method is relatively traditional and has certain disadvantages. For example, it takes a lot of time to tie the wire, and its stability is relatively poor.

[0004] Therefore, it is necessary to provide a new template fixing structure for civil engineering to solve the above technical problems. Utility Model Content

[0007] Preferably, slide rails are fixedly mounted on the top and bottom of the support box, and slide grooves can be opened on the two extension plates. The two slide rails extend into the two slide grooves respectively and are slidably connected thereto.

The connection column 5 is fixedly installed in the middle of the outer wall of one side of the extension plate 4. The two connection columns 5 are symmetrically arranged based on the middle of the support box 1. The two connection columns 5 are respectively fixedly installed on the ends away from each other with side blocks 6 and connecting blocks 8. The side blocks 6 are provided with through holes 7.

A baffle is fixedly installed on one side of the connecting block 8. The plug rod 9 is fixedly installed at the bottom of the baffle. The plug rod 9 fits with the through hole 7.

[0024] The top and bottom of the support box 1 are fixedly installed with slide rails 12, and the two extension plates 4 can be provided with slide grooves 13. The two slide rails 12 extend into the two slide grooves 13 respectively and are slidably connected thereto. Figure 5As shown, in order to prevent the extension plate 4 from being separated from the support box 1, the slide rail 12 and the slide slot 13 adopt a "T"-shaped embedded design, and one side of the two slide slots 13 is set to be open.

[0025] An installation groove 2 may be opened on the outer wall of one side of the support box 1. The horizontal cross-section of the installation groove 2 is "T"-shaped. The top of the installation groove 2 is an opening. A splicing plate 3 is movably installed in the installation groove 2. A T-shaped block is fixedly installed on one side of the splicing plate 3. The T-shaped block is inserted into the installation groove 2. One side of the splicing plate 3 is set as an arc surface for fitting with the circular template.

[0026] Two rotating rods 10 are rotatably installed on the inner walls of both sides of the support box 1, and rotating teeth 11 are fixedly sleeved on the two rotating rods 10. The two rotating rods 10 are respectively close to the two sides of the support box 1, and the two rotating rods 10 are symmetrically arranged based on the midpoint of the support box 1. Tooth plates 14 are fixedly installed on the two extension plates 4, and the two tooth plates 14 are respectively engaged with the two rotating teeth 11.

[0028] An adjusting rod 16 is rotatably installed at the bottom of the supporting box 1, and two bottom plates 15 are fixedly installed at the bottom of the supporting box 1. The two bottom plates 15 are respectively close to the two sides of the supporting box 1, and the adjusting rod 16 is rotatably installed on the two bottom plates 15.

The two vertical plates 18 pass through the two strip openings, and the two vertical plates 18 are respectively located on both sides of the lower slide rail 12.

[0029] The working principle of the template fixing structure for civil engineering provided by the utility model is as follows:

[0030] In civil engineering, when it is necessary to fix the concrete formwork, the worker can first insert the insertion rod 9 into the through hole 7, connect the four support boxes 1 around the concrete formwork, and connect the connecting blocks 8 on the ends of the four support boxes 1 with the side blocks 6 end to end to form a Figure 6 The ring shown.

[0031] Then the staff can rotate the adjusting rod 16 at the bottom of any supporting box 1. The rotation of the adjusting rod 16 will drive the transmission block 17 to move horizontally, thereby driving the two vertical plates 18 to move horizontally. During the horizontal movement of the vertical plate 18, the extension plate 4 located below will be driven to move horizontally. The extension plate 4 drives the corresponding tooth plate 14 to move horizontally, which will cause the corresponding rotating teeth 11 to rotate. At the same time, the two rotating teeth 11 rotate synchronously under the transmission effect of the transmission belt 20. Through the above transmission, when the adjusting rod 16 is rotated, the two extension plates 4 will approach or move away from each other.

[0032] As the adjusting rods 16 are rotated and adjusted successively, the four side blocks 6 and the four connecting blocks 8 gradually fit with the outer wall of the template and are clamped and fixed to each other to form a Figure 6 The state shown is achieved, thereby clamping and fixing the outer wall of the concrete formwork.

[0033] If the circular concrete formwork needs to be fixed, the splicing plate 3 needs to be inserted into the installation groove 2 to form a Figure 1 In the state shown in FIG. 1 , during the installation process, the arc surface of the splicing plate 3 will gradually fit with the outer wall of the circular template, thereby forming a Figure 7 Status shown.

[0034] Compared with the related art, the template fixing structure for civil engineering provided by the utility model has the following beneficial effects:

[0035] The utility model provides a template fixing structure for civil engineering projects. In civil engineering projects, the device connects four support boxes 1 together so that they surround the outer wall of the template, and rotates the adjusting rod 16 to make the connecting columns 5 on both sides approach each other after transmission, so as to clamp the outer wall of the concrete template. The whole process is not only simple and convenient, but also can be flexibly adjusted according to the size of the template, which reduces the labor intensity of the staff and improves the reinforcement effect of the template.
