Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a modular formwork for concrete that does not require roughening. Background Technology

[0002] Currently, in building construction, when dealing with precast concrete components, cup-shaped concrete foundations, and concrete expansion joints, it is common to roughen the concrete at the connection points after formwork removal. Construction workers typically use an electric hammer with a specialized hammer head to roughen the concrete surface. For example, with precast concrete columns, which are usually poured while lying flat, only the two sides can be roughened after formwork removal; the remaining surfaces can only be roughened during lifting. Similarly, for cup-shaped foundations, the inner walls need to be roughened before installing the precast columns. However, the small cross-sectional dimensions of the inner walls of cup-shaped foundations make roughening extremely difficult.

[0003] Existing technologies require roughening operations during the construction of precast concrete components, cup-shaped concrete foundations, and concrete expansion joints. This increases construction time and the risk factor, resulting in significant labor costs and making it difficult to control the quality of the roughening process on the concrete surface. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular formwork for concrete that does not require roughening.

[0005] An embodiment of this utility model provides a modular formwork for concrete that does not require roughening, comprising:

[0006] The building formwork has a back plate on one side, and a number of rubber modules are provided on the back plate. The rubber modules have through holes and bolts are provided in the holes. The back plate has a number of threaded holes, and the bolts extend into the threaded holes and are threadedly connected to them.

[0007] A connecting component for fixing two adjacent building templates together.

[0008] Furthermore, the connecting assembly includes a support block and two round rods. The two round rods are arranged on both sides of the support block. A limiting plate is fixedly provided at one end of each round rod. Limiting grooves are provided on both sides of the support block. The limiting plate is movably arranged in the limiting groove. A threaded rod is fixedly provided at the outer end of each round rod.

[0009] Furthermore, the back plate is provided with multiple fixing holes, and self-tapping screws are installed in the fixing holes. The back plate is fixedly connected to the building formwork by the self-tapping screws.

[0010] Furthermore, the rubber modules are wedge-shaped and distributed in a rectangular array.

[0011] Furthermore, the building template is provided with multiple positioning holes around its perimeter, and the inner side of each positioning hole is provided with an internal thread. The threaded rod extends into the positioning hole and is threadedly connected to it.

[0012] Furthermore, a rotating block is fixedly sleeved on the round rod, and the rotating block is arranged in the shape of a hexagonal prism.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The system incorporates building formwork and rubber modules. After the formwork is installed, several rubber modules can create wedge-shaped grooves on the outer surface of the concrete during pouring. After demolding, the exposed concrete surface can directly meet the roughening quality standards, eliminating the need for manual roughening of the concrete surface using a special electric hammer or iron chisel. This saves labor costs, improves work efficiency, ensures construction quality, and reduces the risk of construction accidents.

[0015] 2. A connecting component is provided. By screwing two threaded rods into the positioning holes of two adjacent building formworks, the two building formworks can be fixedly connected. When facing concrete materials that require roughening on both adjacent surfaces, it can provide good fixed support for the two adjacent building formworks and improve stability.

[0016] In summary, this utility model, through building templates and rubber modules, can form specific grooves on the surface of the poured concrete material, directly achieving the roughening quality standard without the need for separate roughening operations. This improves work efficiency, reduces labor costs, ensures construction quality, and lowers the construction risk factor. Furthermore, the connecting components enable the fixed connection of two adjacent building templates, improving the stability of the pouring process. Attached Figure Description

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a modular formwork for concrete that does not require roughening, comprising:

[0024] Construction template 1 (wood, steel, or resin board are all acceptable). A back panel 2 is provided on one side of the construction template 1. The back panel 2 is made of 3mm thick polyester fiber and nylon. The dimensions of the construction template 1 and the back panel 2 can be customized according to actual needs. Multiple fixing holes 3 are provided through the back panel 2. Self-tapping screws 4 are installed in the fixing holes 3. The self-tapping screws 4 are screwed into the construction template 1 for fixation. The back panel 2 is fixedly connected to the construction template 1 through the self-tapping screws 4.

[0025] The back plate 2 is provided with several rubber modules 5. The number and arrangement of the rubber modules 5 can be customized according to actual needs. The rubber modules 5 are wedge-shaped and distributed in a rectangular array. After the rubber modules 5 are removed, the surface of the exposed concrete reaches the roughening treatment quality standard.

[0026] The rubber module 5 has a through mounting hole 6, and a bolt 7 is installed in the mounting hole 6. The back plate 2 has several threaded holes 8. The bolt 7 extends into the threaded holes 8 and is threadedly connected to them. The rubber module 5 is fixedly connected to the back plate 2 by the bolt 7. The damaged rubber module 5 can be removed and replaced by unscrewing the bolt 7.

[0027] The connecting assembly is used to fix and connect two adjacent building formwork 1s. When facing concrete material where both adjacent surfaces need to be roughened, it can provide good fixation and support for the two adjacent building formwork 1s, improving stability. The connecting assembly includes a support block 10 and two round rods 11. A rotating block 15 is fixedly sleeved on the round rod 11. The rotating block 15 is hexagonal prism-shaped and can be easily rotated by workers. The two round rods 11 are located on both sides of the support block 10. A limit plate 12 is fixedly installed at one end of the round rod 11. Limit grooves 13 are provided on both sides of the support block 10. The limit plate 12 is movably installed in the limit groove 13. The limit groove 13 is as follows: Figure 4The setup shown allows the limiting plate 12 to rotate within the limiting groove 13, and a threaded rod 14 is fixedly provided at the outer end of the round rod 11.

[0028] Multiple positioning holes 9 are provided around the building formwork 1. The inner side of the positioning hole 9 is provided with internal thread. The threaded rod 14 extends into the positioning hole 9 and is threadedly connected to it. By screwing two threaded rods 14 into the positioning holes 9 of two adjacent building formwork 1, the two building formwork 1 can be fixedly connected.

[0029] The detailed working process of this utility model is as follows:

[0030] 1. During installation, first, according to the required roughened surface, set the corresponding number of building templates 1 in the casting mold, then fix the two adjacent building templates 1 in sequence through the support block 10, insert the corresponding two threaded rods 14 into the positioning holes 9 of the two adjacent building templates 1 in sequence, and rotate the round rod 11 through the rotating block 15, and then rotate the threaded rod 14 to tighten and fix the two building templates 1.

[0031] 2. Then the concrete pouring work can be carried out. At this time, several rubber modules 5 can form several wedge-shaped grooves on the outer surface of the concrete material. When the concrete reaches the demolding strength standard, the demolding work of the pouring mold and building formwork 1 is carried out. At this time, the exposed concrete surface can reach the roughening treatment quality standard.

[0032] 3. During disassembly, rotate the two rotating blocks 15 in opposite directions in sequence. The round rod 11 drives the corresponding threaded rod 14 to rotate, so that the two threaded rods 14 are separated from the corresponding positioning holes 9, thereby separating the two adjacent building templates 1.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
