Technical Field
[0001] This invention belongs to the field of prefabricated component technology, and more specifically, relates to a prefabricated assembly and fixing component for building construction. Background Technology
[0002] In the construction of prefabricated concrete structures, the main structural components are prefabricated in the factory and then transported to the construction site for installation and connection into a whole. This can significantly reduce the amount of wet work on the construction site, increase the construction speed, and reduce environmental pollution and energy consumption.
[0003] In practical engineering, the problem of insufficient connection strength after splicing and assembling existing precast wall components is becoming increasingly prominent. The commonly used connection methods for precast wall components, such as simple steel bar lap splicing or grouting sleeve connection, are prone to relative displacement between adjacent components when facing dynamic loads such as earthquakes and strong winds, which can lead to cracks and water seepage at the connection points, reducing the stability and safety of the overall structure. Therefore, we need to propose a prefabricated assembly and fixing components for building construction. Summary of the Invention
[0004] The purpose of this invention is to solve the problem of insufficient connection strength between adjacent prefabricated wall components after splicing in the prior art. When faced with dynamic loads, the adjacent prefabricated wall components are prone to relative displacement, resulting in cracks and water seepage at the connection points, which reduces the stability and safety of the overall structure. Therefore, this invention proposes a prefabricated assembly and fixing component for building construction.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A prefabricated component for building construction includes multiple sets of prefabricated walls. Each set of prefabricated walls has a symmetrically integrally formed interlocking block on one side, and each set of prefabricated walls has a symmetrically formed interlocking groove adapted to the interlocking block on the other side. The interlocking block is used to be inserted into the interlocking groove opened on the side of the adjacent prefabricated wall. A filling channel for concrete injection is left between the adjacent prefabricated walls.
[0007] Two sets of clearance grooves are symmetrically opened on both sides of the multiple sets of precast walls. A connecting rod is fixedly connected to each of the two sets of clearance grooves. A fixing seat is fixedly connected to the end of the connecting rod. A connecting block for connecting adjacent precast walls is inserted into the fixing seat. A stop block for filling and blocking the channel is fixedly connected to the side of the connecting block.
[0008] Preferably, multiple sets of discharge grooves for concrete flow are provided on both sides of the fixing base, and the connecting block is provided with a connecting hole corresponding to the discharge groove.
[0009] Preferably, the two sides of the stop block are in contact with the sides of the adjacent precast wall.
[0010] Preferably, grooves are provided on both sides of the multiple sets of prefabricated walls.
[0011] Preferably, the wall also includes multiple sets of first longitudinal steel bars evenly arranged inside the precast wall, with first connecting steel bars fixedly installed between adjacent first longitudinal steel bars, second connecting steel bars fixedly installed on multiple sets of first longitudinal steel bars, multiple sets of second longitudinal steel bars spaced apart between adjacent first longitudinal steel bars, and fixing steel bars fixedly installed between adjacent second longitudinal steel bars, the fixing steel bars being fixedly installed on the second connecting steel bars.
[0012] Preferably, multiple sets of supporting reinforcing bars are fixedly connected to multiple sets of first longitudinal reinforcing bars near the insertion block, and the supporting reinforcing bars extend into the insertion block to improve the strength of the insertion block.
[0013] Preferably, multiple sets of plug-in rods are fixedly connected to the two sets of first longitudinal steel bars near one end of the precast wall, and one end of each set of plug-in rods extends to the outside of the precast wall. Multiple sets of fixing rods corresponding to the plug-in rods are fixedly connected to the two sets of first longitudinal steel bars near the other end of the precast wall, and one end of each fixing rod extends to the other outside of the precast wall. A connecting seat is fixedly connected to the end of each fixing rod, and a plug-in hole is provided in the connecting seat. The plug-in rod is inserted into the plug-in hole of the connecting seat on the side of the adjacent precast wall.
[0014] Preferably, transverse steel bars are fixedly connected to the two sets of first longitudinal steel bars near both ends of the precast wall, and hanging rings are fixedly connected to the transverse steel bars.
[0015] A fixing component includes prefabricated components for building construction and a base. The prefabricated wall is disposed on the top of the base. Two sets of fixing brackets are fixedly installed on the top of the base via a second connector. The fixing brackets are disposed on both sides of the prefabricated wall. The sides of both sets of fixing brackets abut against the sides of the prefabricated wall. The fixing brackets are fixedly installed on the prefabricated wall via a first connector.
[0016] Preferably, the fixed frame has a filling cavity for concrete injection inside, and a connecting pipe is connected to the fixed frame, with a feed hopper inserted into the connecting pipe.
[0017] Technical effects and advantages of the present invention: The prefabricated components and fixing components for building construction provided by the present invention have the following advantages compared with the prior art:
[0018] This invention, through the design of structures such as fixed seats, connecting blocks, stop blocks, and plug-in blocks, achieves precise positioning during the splicing of precast walls. The plug-in blocks are inserted into the interior of adjacent precast walls, significantly reducing splicing errors and ensuring the accuracy and consistency of wall installation. A filling channel is left between two adjacent sets of precast walls. By inserting the connecting blocks into the fixed seats between these sets, the connection between the two sets of precast walls is effectively limited, restricting relative displacement and giving the splicing points higher load-bearing capacity. Simultaneously, the stop blocks, inserted into the filling channel, act as a barrier. Concrete is injected into the filling channel, and after solidification, it forms a unified whole with the precast walls and connecting components, enhancing the integrity and durability of the precast walls and significantly reducing the risk of joint cracking and water seepage. Furthermore, it eliminates the need for complex formwork support, simplifying on-site operations. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0030] This invention provides, for example Figure 1-9 The prefabricated component of a building structure shown includes multiple sets of prefabricated walls 7. Each set of prefabricated walls 7 has a symmetrically integrally formed interlocking block 8 on one side. Each set of prefabricated walls 7 has a symmetrically formed interlocking groove 9 on the other side that is adapted to the interlocking block 8. The interlocking block 8 is used to be inserted into the interlocking groove 9 opened on the side of the adjacent prefabricated wall 7. A filling channel 28 for concrete injection is left between the adjacent prefabricated walls 7.
[0031] Two sets of clearance grooves 14 are symmetrically opened on both sides of the multiple sets of precast walls 7. A connecting rod 16 is fixedly connected in each of the two sets of clearance grooves 14. A fixing seat 15 is fixedly connected to the end of the connecting rod 16. A connecting block 19 for connecting adjacent precast walls 7 is inserted into the fixing seat 15. A stop block 20 for filling and blocking the channel 28 is fixedly connected to the side of the connecting block 19.
[0032] It should be noted that when splicing adjacent precast walls 7, the plug-in block 8 is pre-inserted into the plug-in groove 9 of the adjacent precast wall 7. The precise positioning function greatly reduces the splicing error and ensures the accuracy and consistency of the wall installation. The fixed seat 15 and the connecting plug 19 form a stable mechanical connection system. Under dynamic load, it effectively limits the relative displacement between precast walls. Compared with the traditional connection method, it can withstand greater seismic force and wind impact, significantly improving the seismic resistance and wind resistance of the overall structure. The block 20 blocks the filling channel 28, so that the two sides of the filling channel 28 form a closed pouring space. On the one hand, it prevents the concrete from overflowing during pouring and ensures the filling density.
[0033] After the concrete solidifies, it forms a whole with the precast walls and connecting components, enhancing the integrity and durability of the connection. In addition, this design can effectively prevent rainwater penetration, avoiding problems such as steel corrosion and concrete deterioration caused by long-term water seepage at the connection, extending the service life of prefabricated buildings, improving the safety and reliability of buildings, and strongly promoting the development and application of prefabricated building technology.
[0034] In an optional embodiment: multiple sets of discharge troughs 17 for concrete flow are provided on both sides of the fixing base 15, and the connecting plug 19 is provided with a connecting hole 18 corresponding to the discharge trough 17.
[0035] It should be noted that, by cooperating with the discharge chute 17 and the connecting hole 18, when filling concrete, the concrete can fall into the filling channel 28 and the clearance groove 14 through the discharge chute 17 and the connecting hole 18, thus filling the filling channel 28 and the clearance groove 14.
[0036] In an alternative embodiment, the two sides of the stop 20 contact the sides of the adjacent precast wall 7.
[0037] It should be noted that concrete is prevented from leaking out from the gap between the stop block 20 and the precast wall 7.
[0038] In an optional embodiment: grooves 21 are provided on both sides of multiple sets of prefabricated walls 7.
[0039] It should be noted that by setting the notch 21, when fixing the precast wall 7, the concrete can enter into the notch 21 and solidify in the notch 21, which can increase the contact area between the precast wall 7 and the concrete and improve the fixing effect of the concrete.
[0040] In an optional embodiment, it further includes multiple sets of first longitudinal steel bars 1 uniformly arranged inside the precast wall 7, with first connecting steel bars 3 fixedly installed between adjacent first longitudinal steel bars 1, second connecting steel bars 4 fixedly installed on multiple sets of first longitudinal steel bars 1, multiple sets of second longitudinal steel bars 2 spaced apart between adjacent first longitudinal steel bars 1, and fixed steel bars 5 fixedly installed between adjacent second longitudinal steel bars 2, with the fixed steel bars 5 fixedly installed on the second connecting steel bars 4.
[0041] It should be noted that the first longitudinal steel bar 1, the second longitudinal steel bar 2, the first connecting steel bar 3, the second connecting steel bar 4, and the fixing steel bar 5 work together to increase the strength of the precast wall 7.
[0042] In an optional embodiment: multiple sets of supporting reinforcing bars 6 are fixedly connected to multiple sets of first longitudinal reinforcing bars 1 near the plug-in block 8, and the supporting reinforcing bars 6 extend into the plug-in block 8 to improve the strength of the plug-in block 8.
[0043] It should be noted that the strength of the plug block 8 can be improved by setting the supporting steel bar 6.
[0044] In an optional embodiment: multiple sets of plug-in rods 10 are fixedly connected to the two sets of first longitudinal steel bars 1 near one end of the precast wall 7, and one end of each set of plug-in rods 10 extends to the outside of the precast wall 7. Multiple sets of fixing rods 11 corresponding to the plug-in rods 10 are fixedly connected to the two sets of first longitudinal steel bars 1 near the other end of the precast wall 7. One end of the fixing rod 11 extends to the other outside of the precast wall 7. A connecting seat 12 is fixedly connected to the end of the fixing rod 11. A plug-in hole 13 is opened in the connecting seat 12. The plug-in rod 10 is inserted into the plug-in hole 13 of the connecting seat 12 on the side of the adjacent precast wall 7.
[0045] It should be noted that by engaging the plug rod 10 and the fixing rod 11 with the connecting seat 12, the fixing screw is fixedly installed in the connecting seat 12, and the threaded end of the fixing screw is pressed against the plug rod 10, thereby fixing the plug rod 10 and improving the connection effect between adjacent precast walls 7.
[0046] In an optional embodiment: transverse steel bars 22 are fixedly connected to the two sets of first longitudinal steel bars 1 near both ends of the precast wall 7, and hanging rings 23 are fixedly connected to the transverse steel bars 22.
[0047] A fixing component includes prefabricated components for building construction and a base 24. A prefabricated wall 7 is disposed on the top of the base 24. Two sets of fixing brackets 25 are fixedly installed on the top of the base 24 through a second connector 29. The fixing brackets 25 are disposed on both sides of the prefabricated wall 7. The sides of both sets of fixing brackets 25 are pressed against the sides of the prefabricated wall 7. The fixing brackets 25 are fixedly installed on the prefabricated wall 7 through a first connector 27.
[0048] It should be noted that the fixing bracket 25 is used to fix the precast wall 7.
[0049] In an optional embodiment: the inside of the fixing frame 25 is provided with a filling cavity 26 for concrete injection, and a connecting pipe 30 is connected to the fixing frame 25, and a feed hopper 31 is inserted into the connecting pipe 30.
[0050] It should be noted that by injecting concrete into the filling cavity 26 and allowing the concrete to solidify within the filling cavity 26, the fixing effect of the fixing frame 25 on the top of the base 24 can be improved, while the fixing effect of the fixing frame 25 on the precast wall 7 can also be improved.
[0051] The usage process of this invention is as follows: When the precast wall 7 needs to be assembled, the hoisting equipment hoists the precast wall 7 to a suitable position through the hanging ring 23, and then places the precast wall 7 on the top of the base 24. After placing the fixing frame 25 on the top of the base 24 and pressing the side of the fixing frame 25 against the side of the precast wall 7, the fixing frame 25 is fixedly installed on the top of the base 24 through the second connector 29, and the fixing frame 25 is fixedly installed on the precast wall 7 through the first connector 27. The precast wall 7 is fixed by the fixing frame 25.
[0052] Using hoisting equipment, another precast wall 7 is placed on top of the base 24, side by side with the fixed precast wall 7. By adjusting the precast wall 7, the precast wall 7 is moved so that the plug block 8 on the side of the precast wall 7 can be inserted into the plug groove 9 on the side of the adjacent precast wall 7. When the plug block 8 is inserted into the plug groove 9, a filling channel 28 is left between the adjacent precast walls 7. When the plug block 8 is inserted into the plug groove 9, the plug rod 10 is inserted into the plug hole 13 of the connecting seat 12 on the adjacent precast wall 7. The fixing screw is threaded into the connecting seat 12 through the filling channel 28 using a tool. The threaded end of the fixing screw is pressed against the plug rod 10, thereby fixing the plug rod 10.
[0053] By inserting the connecting block 19 into the fixing seat 15 between adjacent precast walls 7, the adjacent precast walls 7 are connected by the connecting block 19. After the connecting block 19 is inserted into the fixing seat 15, the stop block 20 is inserted into the filling channel 28 to block the filling channel 28. Concrete is injected into the filling channel 28 and the feed hopper 31. The concrete injected into the filling channel 28 enters the relief groove 14 through the discharge chute 17 and the connecting hole 18, filling the relief groove 14 and the filling channel 28. The concrete is fed into the filling cavity 26 through the feed hopper 31, and then solidifies in the relief groove 14, the filling channel 28 and the filling cavity 26. After the concrete solidifies, it forms a whole with the precast wall 7 and the stop block 20, which enhances the integrity and durability of the precast wall 7, significantly reduces the risk of joint cracking and water seepage, and eliminates the need for complex formwork support, simplifying the on-site operation process. In addition, after the concrete solidifies, the fixing frame 25 can form a whole with the precast wall 7, which enhances the fixing effect on the precast wall 7.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
