Description
Technical Field
[0001] This utility model relates to the technical field of precast wall column installation equipment, and in particular to a precast wall column installation positioning frame. Background Technology
[0002] With the acceleration of industrialization in construction, prefabricated concrete structures have become one of the mainstream development directions in the construction industry due to their advantages such as short construction cycle, low resource consumption, and strong quality control. As key vertical load-bearing components in prefabricated structures, the installation and positioning accuracy of precast walls and columns directly affects the overall load-bearing capacity, seismic performance, and efficiency of subsequent construction processes.
[0003] During the installation of precast wall columns, the core technical point is to achieve precise coaxial connection between the grouting cylinder at the bottom of the component and the pre-reserved underground steel bars on the ground. Only by ensuring that the two are precisely matched can a reliable mechanical force transmission path be formed through subsequent grouting, avoiding potential hazards such as structural stress concentration or incomplete grouting caused by connection deviation.
[0004] In traditional methods of hoisting precast wall columns, workers must manually hold the columns and align the grouting cylinders with the embedded reinforcing bars using mirrors placed on the ground. This method not only significantly increases the labor intensity of workers and prolongs the installation time for individual components, but also poses certain safety hazards. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a prefabricated wall column installation positioning frame.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a precast wall column installation positioning frame, comprising a first frame, a second frame, a hinge assembly, a fixing assembly, a corner positioning assembly, a first positioning frame, and a second positioning frame; both the first frame and the second frame are L-shaped rod structures, with their ends close to each other abutting against each other, forming a rectangular frame structure; the hinge assembly is used to hinge one end of the first frame to one end of the second frame, and the fixing assembly is used to fix the free end of the first frame to the free end of the second frame; the corner positioning assembly is located at the corner of the first frame and the second frame and is used to abut against the buried steel bars to achieve rapid positioning of the precast wall column installation positioning frame; the first positioning frame is fixed to the top of the first frame, and the second positioning frame is fixed to the top of the second frame, the first positioning frame and the second positioning frame cooperate and splice into a square funnel-shaped structure to guide and limit the precast wall column hoisted into the funnel-shaped structure.
[0007] By adopting the above technical solution, through the contact action between the corner positioning component and the buried steel reinforcement, workers can quickly position the precast wall column installation positioning frame. After the first and second frames are spliced into a rectangular frame structure, the fixing component ensures the stability of the first and second frames during use. The square funnel-shaped structure formed by the splicing of the first and second positioning frames plays a good guiding and limiting role for the precast wall column, allowing the grouting cylinder at the bottom of the precast wall column to quickly align with the buried steel reinforcement after the precast wall column descends into the funnel-shaped structure. This eliminates the cumbersome operation of workers having to hold the precast wall column by hand and match the grouting cylinder with the buried steel reinforcement according to the mirror set on the ground, which is a traditional technique. This improves the installation efficiency of the precast wall column and ensures the safety of the operation.
[0008] Furthermore, the corner positioning component includes a first positioning block and a second positioning block. The first positioning block is fixed at the inner corner of the first frame, and the second positioning block is fixed at the inner corner of the second frame. The first positioning block and the second positioning block are each provided with a first arc-shaped groove that cooperates with the side wall of the buried steel bar on the side that is close to each other.
[0009] By adopting the above technical solution, after the first frame and the second frame are spliced into a rectangular frame structure, the first arc-shaped groove on the first positioning block and the first arc-shaped groove on the second positioning block respectively abut against the buried steel bars at two diagonal positions, thereby playing a role in quickly positioning the assembly of the first frame and the second frame, so that the grouting cylinder at the bottom of the precast wall column and the buried steel bars can be quickly aligned.
[0010] Furthermore, the corner positioning component also includes a third positioning block and a fourth positioning block. The third positioning block is fixed to the inner side of the first frame near its end. The third positioning block has two symmetrically distributed corners about the first frame, and the third positioning block has a second arc-shaped groove that mates with the side wall of the buried steel bar. The fourth positioning block is fixed to the inner side of the second frame near its end. The fourth positioning block has two symmetrically distributed corners about the second frame, and the fourth positioning block has a third arc-shaped groove that mates with the side wall of the buried steel bar.
[0011] By adopting the above technical solution, the second arc-shaped groove on the third positioning block and the third arc-shaped groove on the fourth positioning block both play a good auxiliary positioning role, further ensuring the installation accuracy and efficiency of the first frame and the second frame.
[0012] Furthermore, a first weight-reducing hole is provided through the lower part of the first positioning frame, and a first protective pad is attached and fixed to the upper inner side of the first positioning frame; a second weight-reducing hole is provided through the lower part of the second positioning frame, and a second protective pad is attached and fixed to the upper inner side of the second positioning frame.
[0013] By adopting the above technical solution, the design of the first and second weight-reducing holes reduces the weight of the first and second positioning frames, resulting in a lightweight precast wall column installation positioning frame. Both the first and second protective pads can be made of flexible materials, such as rubber or plastic sheets, which can provide good protection for the inner sides of the inclined portions of both the first and second positioning frames, thus reducing wear during the installation of the precast wall columns.
[0014] Furthermore, the hinge assembly includes a first connector, a second connector, and a hinge shaft. The first connector is fixed to the outer side of the first frame near one end, and the second connector is fixed to the outer side of the second frame near one end. The second connector and the first connector are offset vertically. The hinge shaft passes through the first connector and the second connector and is clearance-fitted to both.
[0015] By adopting the above technical solution, the first frame and the second frame can rotate around the hinge axis to complete the splicing of the rectangular frame structure, thereby enabling the first positioning frame and the second positioning frame to be quickly spliced into a square funnel-shaped structure, thus providing a guiding and limiting foundation for the precast wall columns.
[0016] Furthermore, a circular through hole is provided through the first connector.
[0017] By adopting the above technical solution, it is easier for workers to pass ropes through the circular through hole, thus improving the portability of the precast wall column installation positioning frame.
[0018] Furthermore, the fixing component includes a first U-shaped block, a second U-shaped block, a connecting shaft, and a wing nut. The first U-shaped block is fixed on the outer side of the first frame away from the first connector, and the second U-shaped block is fixed on the outer side of the second frame away from the second connector, with the groove of the second U-shaped block corresponding to the groove of the first U-shaped block. One end of the connecting shaft is hinged inside the second U-shaped block, and the wing nut is sleeved on the connecting shaft and threadedly connected to it, with the diameter of the wing nut on the side closer to the first U-shaped block being larger than the inner width of the first U-shaped block.
[0019] By adopting the above technical solution, after the first and second frames are assembled into a rectangular frame structure, workers need to tighten the wing nuts to ensure the stability of the first and second frames, as well as the first and second positioning frames, during use (when the hoisted precast wall columns descend into the square funnel-shaped structure). After the installation of the precast wall columns is completed, workers only need to loosen the wing nuts to rotate the first and second frames, thereby opening the first and second positioning frames to facilitate the installation of other precast wall columns.
[0020] Furthermore, a limiting block is fixed at the end of the connecting shaft away from the second U-shaped block, and the diameter of the limiting block is larger than the diameter of the connecting shaft.
[0021] By adopting the above technical solution, the limiting block plays a good role in limiting the wing nut, reducing the probability of the wing nut being lost.
[0022] In summary, this utility model has the following beneficial effects: In this application, the corner positioning component and the embedded steel reinforcement abut against each other, enabling workers to quickly position the precast wall column installation positioning frame. After the first and second frames are spliced into a rectangular frame structure, the fixing component ensures the stability of the first and second frames during use. The square funnel-shaped structure formed by the splicing of the first and second positioning frames plays a good guiding and limiting role for the precast wall column, allowing the grouting cylinder at the bottom of the precast wall column to quickly align with the embedded steel reinforcement after the precast wall column descends into the funnel-shaped structure. This eliminates the cumbersome operation of workers manually holding the precast wall column and matching the grouting cylinder with the embedded steel reinforcement according to a mirror set on the ground, which is required in traditional technology. This improves the installation efficiency of the precast wall column and ensures the safety of the operation. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0026] like Figure 1-8 As shown in the figure, this application discloses a prefabricated wall column installation positioning frame, including a first frame 1, a second frame 2, a hinge assembly 3, a fixing assembly 4, a corner positioning assembly 5, a first positioning frame 6, and a second positioning frame 7; both the first frame 1 and the second frame 2 are L-shaped rod structures, with their adjacent ends abutting against each other, forming a rectangular frame structure; the hinge assembly 3 is used to hinge one end of the first frame 1 to one end of the second frame 2, fixing... Component 4 is used to fix the free end of the first frame 1 to the free end of the second frame 2; the corner positioning component 5 is set at the corner of the first frame 1 and the second frame 2 and is used to abut against the buried steel bars to realize the rapid positioning of the precast wall column installation positioning frame; the first positioning frame 6 is fixed to the top of the first frame 1 and the second positioning frame 7 is fixed to the top of the second frame 2. The first positioning frame 6 and the second positioning frame 7 cooperate and splice into a square funnel-shaped structure to guide and limit the precast wall column hoisted into the funnel-shaped structure.
[0027] Through the contact between the corner positioning component 5 and the buried steel reinforcement, workers can quickly position the precast wall column installation positioning frame. After the first frame 1 and the second frame 2 are spliced into a rectangular frame structure, the fixing component 4 ensures the stability of the first frame 1 and the second frame 2 during use. The square funnel-shaped structure formed by splicing the first positioning frame 6 and the second positioning frame 7 plays a good guiding and limiting role for the precast wall column, so that after the precast wall column is lowered into the funnel-shaped structure, the grouting cylinder at the bottom of the precast wall column and the buried steel reinforcement are quickly aligned. This eliminates the cumbersome operation of workers having to hold the precast wall column by hand and match the grouting cylinder and the buried steel reinforcement according to the mirror set on the ground in the traditional technology, thus improving the installation efficiency of the precast wall column.
[0028] The corner positioning component 5 includes a first positioning block 51 and a second positioning block 52. The first positioning block 51 is fixed at the inner corner of the first frame 1, and the second positioning block 52 is fixed at the inner corner of the second frame 2. The first positioning block 51 and the second positioning block 52 are provided with a first arc-shaped groove 8 that cooperates with the side wall of the buried steel bar on the side that are close to each other.
[0029] After the first frame 1 and the second frame 2 are assembled into a rectangular frame structure, the first arc-shaped groove 8 on the first positioning block 51 and the first arc-shaped groove 8 on the second positioning block 52 respectively abut against the buried steel bars at two diagonal positions, thereby playing a role in quickly positioning the assembly of the first frame 1 and the second frame 2, so that the grouting cylinder at the bottom of the precast wall column and the buried steel bars can be quickly aligned (the installation positions of the first positioning frame 6 and the second positioning frame 7 match the size of the precast wall column).
[0030] The corner positioning component 5 also includes a third positioning block 53 and a fourth positioning block 54. The third positioning block 53 is fixed to the inner side of the first frame 1 near its end. The third positioning block 53 has two symmetrically distributed corners about the first frame 1, and a second arc-shaped groove 531 that mates with the side wall of the buried steel reinforcement. The fourth positioning block 54 is fixed to the inner side of the second frame 2 near its end. The fourth positioning block 54 has two symmetrically distributed corners about the second frame 2, and a third arc-shaped groove 541 that mates with the side wall of the buried steel reinforcement. The second arc-shaped groove 531 on the third positioning block 53 and the third arc-shaped groove 541 on the fourth positioning block 54 both provide good auxiliary positioning, further ensuring the installation accuracy and efficiency of the first frame 1 and the second frame 2.
[0031] The lower part of the first positioning frame 6 is provided with a first weight reduction hole 61, and the upper inner side of the first positioning frame 6 is fitted and fixed with a first protective pad 62; the lower part of the second positioning frame 7 is provided with a second weight reduction hole 71, and the upper inner side of the second positioning frame 7 is fitted and fixed with a second protective pad 72.
[0032] The design of the first weight-reducing hole 61 and the second weight-reducing hole 71 reduces the weight of the first positioning frame 6 and the second positioning frame 7, resulting in a lightweight precast wall column installation positioning frame. Both the first protective pad 62 and the second protective pad 72 can be made of flexible materials, such as rubber or plastic sheets, which can provide good protection for the inner sides of the inclined portions of the first positioning frame 6 and the second positioning frame 7, thus reducing wear during the installation of the precast wall column.
[0033] The hinge assembly 3 includes a first connector 31, a second connector 32, and a hinge shaft 33. The first connector 31 is fixed to the outside of the first frame 1 near one end, and the second connector 32 is fixed to the outside of the second frame 2 near one end. The second connector 32 and the first connector 31 are offset vertically. The hinge shaft 33 passes through the first connector 31 and the second connector 32 and is clearance-fitted to both of them (in actual use, both ends of the hinge shaft 33 are provided with rivet plates, i.e., circular pieces with a diameter larger than the diameter of the hinge shaft 33).
[0034] This allows the first frame 1 and the second frame 2 to rotate around the hinge axis 33, so as to complete the splicing of the rectangular frame structure. This allows the first positioning frame 6 and the second positioning frame 7 to be quickly spliced into a square funnel-shaped structure, thereby providing a guiding and limiting foundation for the precast wall columns.
[0035] A circular through hole 9 is provided on the first connector 31, which makes it easy for workers to pass the rope through the circular through hole 9, thus improving the portability of the precast wall column installation positioning frame.
[0036] The fixing component 4 includes a first U-shaped block 41, a second U-shaped block 42, a connecting shaft 43, and a wing nut 44. The first U-shaped block 41 is fixed on the outer side of the first frame 1 away from the first connector 31. The second U-shaped block 42 is fixed on the outer side of the second frame 2 away from the second connector 32, and the groove of the second U-shaped block 42 corresponds to the groove of the first U-shaped block 41. One end of the connecting shaft 43 is hinged inside the second U-shaped block 42. The wing nut 44 is sleeved on the connecting shaft 43 and threadedly connected to it. The diameter of the wing nut 44 on the side closer to the first U-shaped block 41 is greater than the inner width of the first U-shaped block 41.
[0037] After the first frame 1 and the second frame 2 are assembled into a rectangular frame structure, the workers need to tighten the wing nuts 44 to ensure the stability of the first frame 1, the second frame 2, the first positioning frame 6, and the second positioning frame 7 during use (when the hoisted precast wall column is lowered into the square funnel-shaped structure). After the installation of the precast wall column is completed, the workers only need to loosen the wing nuts 44 to rotate the first frame 1 and the second frame 2, thereby opening the first positioning frame 6 and the second positioning frame 7 to facilitate the installation of other precast wall columns. The shape of the first U-shaped block 41 and the second U-shaped block 42 allows the workers to open or close the second frame 2 without completely unscrewing the wing nuts 44.
[0038] A limiting block 431 is fixed to the end of the connecting shaft 43 away from the second U-shaped block 42, and the diameter of the limiting block 431 is larger than the diameter of the connecting shaft 43. The limiting block 431 plays a good role in limiting the wing nut 44, reducing the probability of the wing nut 44 being lost.

All technical solutions falling within the scope of this utility model's concept are protected.
