Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to formwork for prefabricated building construction. Background Technology

[0002] Formwork for prefabricated building construction is a model tool used in the process of pouring concrete components to form the shape and size required by the design. It is one of the important tools to ensure the quality of prefabricated building components and construction efficiency. It provides the concrete with precise shape and size to ensure that the prefabricated components meet the design requirements. For example, prefabricated wall panels, prefabricated floor slabs, prefabricated stairs and other components all need to be formed into specific shapes through formwork.

[0003] A search revealed Chinese Patent Publication No. CN218952781U, which discloses a quick-release prefabricated formwork structure for building construction, belonging to the field of building construction technology. It includes a formwork body and a fixing box fixed to one side of the formwork body. Two positioning blocks are symmetrically fixed to the outer wall of the formwork body away from the fixing box, and connecting rods are fixedly connected to the outer wall of the positioning blocks away from the formwork body. A fixing column is fixedly connected inside the fixing box, and two sliding rods are slidably connected to the outside of the fixing column. Positioning pins are fixedly connected to the opposite sides of the two sliding rods. Two support springs for supporting the sliding rods are sleeved on the outside of the fixing column. A fixing block is fixedly connected to the back of the fixing box. Quick-release prefabricated formwork structures for construction can not only quickly assemble and disassemble two formwork bodies, but also ensure the stability of the connection between the two formwork bodies. However, the formwork is heavy, and the handling and installation require specialized machinery, which increases construction costs and difficulty. It also puts a lot of physical exertion on construction workers. Optimizing the formwork hoisting scheme can improve construction efficiency, reduce the use time and cost of machinery, and strengthen the training of construction workers to improve their operating skills and reduce labor intensity. However, gaps exist at the joints of the formwork. During the concrete pouring process, cement slurry will flow out from the gaps, causing defects such as pitting and honeycomb on the concrete surface, affecting the appearance quality of the concrete and reducing its strength and durability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a formwork for prefabricated building construction, which aims to improve the problem that cement slurry will flow out from the gaps during the concrete pouring process, resulting in pitting and honeycomb defects on the concrete surface, affecting the appearance quality of the concrete, and reducing the strength and durability of the concrete.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated building construction template, including a foundation, with load-bearing rods fixedly connected at equal intervals on the left side of the outer wall of the foundation, an outer wall fixedly connected to the left side of the load-bearing rods, a support plate fixedly connected to the inner side of the load-bearing rods, a clamping block one fixedly connected to the front side of the load-bearing rods, and a clamping block two fixedly connected to the rear side of the load-bearing rods, with a sealing gasket installed in the middle of the clamping blocks one and two, a fixing block two fixedly connected at equal intervals on the left side of the outer wall of the outer wall, and a fixing block one fixedly connected at equal intervals on the left side of the outer wall of another outer wall, with a threaded rod rotatably connected to the inner wall of the fixing block one, and a fixing block two slidably connected to the inner side of the fixing block one, and multiple support mechanisms installed at equal intervals on the bottom left side of the outer wall, the support mechanisms being used to support the panel, bear the weight and lateral pressure during concrete pouring, and ensure the stability and strength of the template.

[0006] The above technical solution involves aligning two exterior walls together, placing the sealing gasket in the middle of clamping block one and clamping block two, and then aligning and splicing the two exterior walls towards the sealing gasket. The sealing gasket interlocks with the textures of clamping block one and clamping block two. Fixing block one and fixing block two are installed on the outer side of the exterior walls. After the exterior walls are aligned and spliced ​​together, fixing block two will slide into the inner side of fixing block one. At this time, rotating the threaded rod will allow the threaded rod to enter the threaded hole on the outer wall of fixing block two. Tightening the threaded rod will fix fixing block one and fixing block two together, thus fixing the two exterior walls. This ensures that fixing block one and fixing block two are tightly fitted with the sealing gasket, preventing cement slurry from flowing out of the gaps in the exterior walls and causing defects such as pitting and honeycomb on the surface of the concrete layer, effectively improving the strength and durability of the concrete layer.

[0007] As a further description of the above technical solution:

[0008] The support mechanism includes a fixing plate one, which is equidistantly installed on the bottom left side of the outer wall. The inner wall of the fixing plate one is threaded with bolts one at equal intervals. The inner side of the fixing plate one is fitted with a fixing plate two, and the inner right side of the inner wall of the fixing plate two is threaded with bolts two. A gasket is installed at the bottom of the inner wall of the fixing plate two, and the inner side of the gasket is threaded with bolts three.

[0009] The above technical solution involves: tightly attaching fixing plate one to the junction of the exterior wall and the ground; screwing bolt one into the exterior wall and the ground respectively; placing fixing plate two inside fixing plate one; screwing bolt two into the right side of the inner wall of fixing plate two; connecting fixing plate two to the exterior wall; placing a gasket on the bottom wall of fixing plate two; and screwing bolt three into the bottom wall of fixing plate two to penetrate into the ground, thus tightly connecting fixing plate one to the ground. This improves the grip of fixing plate one on the ground, supporting the exterior wall, bearing the weight and lateral pressure of the concrete layer, and ensuring the stability and strength of the panel.

[0010] As a further description of the above technical solution:

[0011] An isolation layer is installed on top of the foundation, and a concrete layer is installed on top of the isolation layer.

[0012] Through the above technical solution, the concrete layer is the main load-bearing component of the prefabricated building structure, bearing the building's self-weight, service load, and external forces such as wind load and seismic load, providing stable structural support for the building.

[0013] As a further description of the above technical solution:

[0014] A crossbeam is fixedly connected to the top of the load-bearing rod.

[0015] The above technical solution involves connecting the load-bearing rods laterally with the crossbeams, thus linking the load-bearing rods into a whole and forming a stable spatial system.

[0016] As a further description of the above technical solution:

[0017] A steel frame is fixedly connected to the top of the crossbeam, and a connecting frame is fixedly connected to the middle of the inner side of the steel frame.

[0018] The above technical solution involves a horizontally arranged steel frame that connects the load-bearing rods, withstands the horizontal force transmitted from the formwork, and transfers the force to the load-bearing rods. It also serves to fix the position of the formwork.

[0019] As a further description of the above technical solution:

[0020] A hanger rod is installed in the middle of the bottom wall of the crossbeam.

[0021] The above technical solution involves suspending the formwork on an upper supporting structure, such as the main structure of a building or a specially designed support system, using a hanger to ensure the formwork is in the correct position and provides space for concrete pouring.

[0022] As a further description of the above technical solution:

[0023] A long plate is fixedly connected to the bottom end of the boom.

[0024] The above technical solution involves providing various connection holes, slots, or bolt holes in the long plate, which facilitates the assembly and disassembly of the template by construction workers using bolts, pins, clamps, and other connecting parts, thereby improving construction efficiency and reducing installation time and labor intensity.

[0025] As a further description of the above technical solution:

[0026] A mounting plate is fixedly connected to the bottom of the long plate.

[0027] Through the above technical solution: the mounting plate has good integrity and continuity, can save templates, and the upper and lower surfaces of the plate are flat, which facilitates the decoration of the finishing layer.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, two exterior walls are aligned and placed together. A sealing gasket is placed in the middle of clamping block one and clamping block two. Then, the two exterior walls are aligned and spliced ​​towards the sealing gasket. The sealing gasket and the texture of clamping block one and clamping block two interlock. Fixing block one and fixing block two are installed on the outer side of the exterior walls. After the exterior walls are aligned and spliced ​​together, fixing block two will slide into the inner side of fixing block one. At this time, the threaded rod is rotated, and the threaded rod will enter the threaded hole on the outer wall of fixing block two. The threaded rod is rotated and tightened to fix fixing block one and fixing block two together, which can fix the two exterior walls. This makes fixing block one and fixing block two fit tightly with the sealing gasket, preventing cement slurry from flowing out from the gaps in the exterior walls, which would cause defects such as pitting and honeycomb on the surface of the concrete layer. This effectively improves the strength and durability of the concrete layer.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a prefabricated building construction template, including a foundation 7. Load-bearing rods 14 are fixedly connected at equal intervals to the left side of the outer wall of the foundation 7. An outer wall 1 is fixedly connected to the left side of the load-bearing rods 14. A support plate 15 is fixedly connected to the inner side of the load-bearing rods 14. A clamping block 3 is fixedly connected to the front side of the load-bearing rods 14, and a clamping block 5 is fixedly connected to the rear side of the load-bearing rods 14. A sealing gasket 4 is installed in the middle of the clamping blocks 3 and 5. A fixing block 8 is fixedly connected at equal intervals to the left side of the outer wall 1. A fixing block 6 is fixedly connected at equal intervals on the left side of the outer wall of an exterior wall 1. A threaded rod 9 is rotatably connected to the inner wall of the fixing block 6. A second fixing block 8 is slidably connected to the inner side of the fixing block 6. The two exterior walls 1 are precisely aligned and placed. A sealing gasket 4 is placed between clamping blocks 3 and 5. Then, the two exterior walls 1 are precisely spliced ​​towards the sealing gasket 4. The texture of the sealing gasket 4 matches the texture of clamping blocks 3 and 5. The outer side of the exterior wall 1 is equipped with fixing blocks 6 and 8. After the exterior wall 1 is spliced, the fixing blocks... The second block 8 will slide into the inside of the first fixed block 6. At this time, rotate the threaded rod 9 so that it enters the threaded hole on the outer wall of the second fixed block 8. Tighten the threaded rod 9 to fix the first fixed block 6 and the second fixed block 8 together. In this way, the two outer walls 1 are stabilized, ensuring that the first fixed block 6 and the second fixed block 8 are tightly fitted with the sealing gasket 4, effectively preventing cement slurry from flowing out from the gaps in the outer wall 1, avoiding pitting and honeycomb defects on the surface of the concrete layer 18, thereby improving the strength and durability of the concrete layer 18. Multiple support mechanisms 2 are installed at equal intervals on the bottom left side of the outer wall 1. The support mechanisms 2 are used to support the panel and bear the weight and lateral pressure during concrete pouring, ensuring the stability and strength of the formwork. An isolation layer 19 is installed on the top of the foundation 7, and the concrete layer 18 is installed on the top of the isolation layer 19. The top of the load-bearing rod 14 is fixedly connected to the crossbeam 10. The concrete layer 18 is the main load-bearing component of the prefabricated building structure, bearing the self-weight of the building, construction load, and external forces such as wind load and seismic load, providing stable structural support for the building.

[0040] Specifically, the two exterior walls 1 are aligned and placed together. The sealing gasket 4 is placed in the middle of clamping block 3 and clamping block 5. Then, the two exterior walls 1 are aligned and spliced ​​towards the sealing gasket 4. The sealing gasket 4 and the patterns of clamping block 3 and clamping block 5 interlock. Fixing block 6 and fixing block 8 are installed on the outer side of the exterior wall 1. After the exterior walls 1 are aligned and spliced ​​together, fixing block 8 will slide into the inner side of fixing block 6. At this time, the threaded rod 9 is rotated and will enter the threaded hole on the outer wall of fixing block 8. The threaded rod 9 is rotated and tightened to fix fixing block 6 and fixing block 8 together. This fixes the two exterior walls 1, making fixing block 6 and fixing block 8 fit tightly with the sealing gasket 4. This prevents cement grout from flowing out from the gaps in the exterior walls 1, which would cause defects such as pitting and honeycomb on the surface of the concrete layer 18. This effectively improves the strength and durability of the concrete layer 18.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The support mechanism 2 includes a fixing plate 201, which is equidistantly installed on the bottom left side of the outer wall 1. Bolts 202 are threaded at equal intervals along the inner wall of the fixing plate 201. A fixing plate 205 is installed on the inner side of the fixing plate 201. Bolts 204 are threaded along the right side of the inner wall of the fixing plate 205. A washer 203 is installed at the bottom of the inner wall of the fixing plate 205. Bolts 206 are threaded along the inner side of the washer 203. Bolt 201 is tightly fitted to the connection between the exterior wall 1 and the ground. Bolt 202 is then screwed into the pre-drilled holes in both the exterior wall 1 and the ground. Next, fixing plate 205 is placed inside fixing plate 201. Bolt 204 is screwed into the right side of the inner wall of fixing plate 205 to connect fixing plate 205 to the exterior wall 1. Then, washer 203 is placed on the bottom wall of fixing plate 205, and bolt 206 is screwed into the bottom wall of fixing plate 205. The fixing plate 201 is firmly bonded to the ground by passing through the ground. This is to enhance the adhesion between the fixing plate 201 and the ground, thereby supporting the exterior wall 1, bearing the weight and lateral pressure of the concrete layer 18, and ensuring the stability and strength of the panel. A steel frame 11 is fixedly connected to the top of the beam 10. The beam 10 is horizontally connected to the load-bearing rods 14, connecting each load-bearing rod 14 into a whole, so that the structure forms a stable spatial system. A connecting frame 12 is fixedly connected to the middle of the inner side of the steel frame 11. The steel frame 11 is arranged horizontally to connect the load-bearing rods 14, bear the horizontal force transmitted from the formwork, and transmit the force to the load-bearing rods 14. It also serves to fix the position of the formwork. A hanger 13 is installed in the middle of the bottom wall of the beam 10. The hanger 13 suspends the formwork on the supporting structure above, such as the main structure of the building or a specially set support system, so that the formwork is in the correct position and provides forming space for concrete pouring.

[0042] Specifically, fixing plate 201 is tightly attached to the connection between the exterior wall 1 and the ground. Bolt 202 is screwed into the exterior wall 1 and the ground respectively. Fixing plate 205 is placed inside fixing plate 201. Bolt 204 is screwed into the right side of the inner wall of fixing plate 205, connecting fixing plate 205 to the exterior wall 1. Washer 203 is placed on the bottom wall of fixing plate 205. Bolt 306 is screwed into the bottom wall of fixing plate 205 to penetrate into the ground, tightly connecting fixing plate 201 to the ground, improving the grip of fixing plate 201 to the ground, supporting the exterior wall 1, bearing the weight and lateral pressure of the concrete layer 18, and ensuring the stability and strength of the panel.

[0043] Reference Figure 1 , Figure 2 and Figure 3The bottom end of the rod 13 is fixedly connected to a long plate 16, and the bottom of the long plate 16 is fixedly connected to a mounting plate 17.

[0044] Specifically, the formwork is suspended from the supporting structure above, such as the main structure of the building or a specially designed support system, by the hanger rod 13, so that the formwork is in the correct position and provides forming space for concrete pouring. The long plate 16 is provided with various connection holes, slots or bolt holes, which makes it convenient for construction workers to use bolts, pins, clamps and other connectors to assemble and disassemble the formwork, improve construction efficiency, reduce installation time and labor intensity. The installation plate 17 has good integrity and continuity, which can save formwork. The upper and lower surfaces of the plate are flat, which is convenient for finishing layer decoration.

[0045] Working principle: First, place the two exterior walls 1 side by side, ensuring their edges are aligned. Next, place the sealing gasket 4 in the middle of clamping blocks 3 and 5, ensuring the sealing gasket 4 is in the proper position. Then, align and splice the two exterior walls 1 towards the sealing gasket 4, so that the patterns of the sealing gasket 4 interlock with those of clamping blocks 3 and 5, ensuring a tight fit between the sealing gasket 4 and the clamping blocks. Fixing blocks 6 and 8 are installed on the outer side of the exterior walls 1. These two fixing blocks play a crucial role in splicing the exterior walls 1. After the exterior walls 1 are aligned and spliced ​​together, fixing block 8 will slide into fixing block 6. On the inner side, a stable structure is formed; at this time, by rotating the threaded rod 9, the threaded rod 9 will enter the threaded hole on the outer wall of the second fixing block 8. Continue to rotate and tighten the threaded rod 9 to firmly fix the first fixing block 6 and the second fixing block 8 together, thereby ensuring the stable connection of the two outer wall blocks 1; this operation can make the first fixing block 6 and the second fixing block 8 fit tightly with the sealing gasket 4, effectively preventing cement grout from flowing out from the gaps in the outer wall 1, avoiding defects such as pitting and honeycomb on the surface of the concrete layer 18. In this way, the strength and durability of the concrete layer 18 can be significantly improved, ensuring the stability and safety of the building structure;

[0046] To ensure the stability of the connection between the exterior wall 1 and the ground, firstly, the fixing plate 201 needs to be tightly fitted to the connection point between the exterior wall 1 and the ground, ensuring that the contact surfaces of the fixing plate 201 with the exterior wall 1 and the ground are flat and without gaps. Next, screw the bolts 202 into the exterior wall 1 and the ground respectively, ensuring that the bolts 202 are firmly fixed in the appropriate positions. Then, place the fixing plate 205 inside the fixing plate 201, ensuring that the fixing plate 205 fits tightly with the fixing plate 201. Finally, screw the bolts 204 into the right side of the inner wall of the fixing plate 205 to further strengthen the connection between the fixing plate 205 and the ground. For the connection of the exterior wall 1, the gasket 203 is placed on the bottom wall of the fixing plate 205. The function of the gasket 203 is to distribute the pressure and protect the bolt 3 206 from damage. Finally, the bolt 3 206 is screwed into the bottom wall of the fixing plate 205, ensuring that the bolt 3 206 passes through the ground, and the fixing plate 1 201 is tightly connected to the ground. Through this structural design, the grip of the fixing plate 1 201 on the ground can be significantly improved, thereby effectively supporting the exterior wall 1 and bearing the weight and lateral pressure of the concrete layer 18. This measure ensures the stability and strength of the panel and provides a solid foundation for the entire building structure.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
