Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement cage technology, and in particular to a steel reinforcement cage structure suitable for prefabricated foundations. Background Technology

[0002] Pile cap foundations are a common type of foundation used in modern construction. The pile cap bears all the loads transmitted from the superstructure columns and transfers them to the lower pile foundations, ensuring the safety of the building foundation and playing a vital role in building construction. For pile cap foundation construction, the efficiency of the reinforcement installation significantly impacts the overall construction speed.

[0003] The existing foundation reinforcement construction process is a sequential construction process, where the next process can only begin after the previous one is completed. That is, the earthwork excavation and the waterproofing of the foundation layer must be completed before the reinforcement cage of the foundation can be tied. However, tying reinforcement structures on-site consumes construction time, requires a large amount of labor, is easily affected by the weather at the construction site, and has low construction efficiency. Therefore, the sequential construction process is no longer suitable for rapid project construction. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a steel reinforcement frame structure suitable for prefabricated foundations, which can solve the problems that on-site steel reinforcement binding consumes construction time, requires a large amount of labor, is easily affected by the weather at the construction site, and has low construction efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A steel reinforcement frame structure suitable for prefabricated foundations includes steel reinforcement positioning calipers. Four steel reinforcement positioning calipers are welded together to form a "well"-shaped steel reinforcement positioning grid. Two steel reinforcement positioning grids are provided. The two steel reinforcement positioning grids are connected by four connecting columns. The upper steel reinforcement positioning grid has lifting ropes wrapped around the four intersection points. The ends of the four lifting ropes away from the steel reinforcement positioning grid converge at one point.

[0009] Among them, multiple foundation steel bars are clamped in both the horizontal and vertical positions between the two steel bar positioning frames, and the multiple foundation steel bars and the two steel bar positioning frames form a precast steel cage.

[0010] Preferably, the rebar positioning caliper includes long rebars and short rebars, with multiple short rebars. The short rebars are fixedly welded to the long rebars, and two short rebars form a groove. The width of the groove is equal to the diameter of the foundation rebar.

[0011] Preferably, the four connecting columns are welded to the four intersections of the two steel reinforcement positioning grids.

[0015] Preferably, the junctions of the multiple foundation steel bars and the steel bar positioning grid, as well as the cross intersections of the multiple foundation steel bars, are connected by binding wire.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a steel reinforcement frame structure suitable for prefabricated foundations, including a steel reinforcement positioning caliper 1. The steel reinforcement positioning caliper 1 includes long steel bars 2 and short steel bars 3. Multiple short steel bars 3 are provided, and the short steel bars 3 are fixedly welded to the long steel bars 2.

[0030] It should be noted that, as Figure 6 As shown, the length of the long reinforcing bar 2 is equal to the length of the reinforcing cage. Two short reinforcing bars 3 form a slot, the width of which is equal to the diameter of the foundation reinforcing bar 6. The distance between the two slots is equal to the distance between the two foundation reinforcing bars 6.

[0031] Furthermore, the diameter of the long reinforcing bar 2 is 16mm. The diameter of the short reinforcing bar 3 is 12mm, and its length is 100mm.

[0032] The position of the reinforcing bars on the foundation reinforcing cage is fixed by using a reinforcing bar positioning caliper 1 to prevent deformation and displacement of the reinforcing bars during transportation and hoisting.

[0033] Furthermore, such as Figure 2 As shown, four rebar positioning calipers 1 are welded together to form a "well"-shaped rebar positioning grid 7. Two rebar positioning grids 7 are provided, arranged vertically to form a rebar skeleton structure. The two rebar positioning grids 7 are connected by four connecting columns 4 welded together.

[0034] Among them, the four connecting columns 4 are respectively welded to the intersection of two steel bar positioning calipers 1 in the same steel bar positioning grid 7.

[0035] like Figure 1 and Figure 5 As shown, the slot openings on the two rebar positioning mesh frames 7 are arranged opposite each other, and multiple foundation rebars 6 are correspondingly engaged in the slots between the two rebar positioning mesh frames 7. The multiple foundation rebars 6 and the two rebar positioning mesh frames 7 form a precast rebar cage 8.

[0036] like Figure 3 As shown, lifting ropes 5 are wrapped around the four intersection points of the upper-layer rebar positioning mesh frame 7, and the ends of the four lifting ropes 5 away from the rebar positioning mesh frame 7 converge at one point. The lifting ropes 5 are used to connect the rebar positioning mesh frame 7, enabling the movement of the rebar skeleton structure and the rebar cage.

[0037] Furthermore, such as Figure 5 As shown, the distance between the two steel reinforcement positioning frames 7 is adapted to the height of the foundation steel reinforcement 6.

[0038] Furthermore, such as Figure 4 As shown, the foundation reinforcement 6 is set as a ring stirrup to improve the overall integrity of the reinforcement cage. Multiple foundation reinforcement bars 6 are inserted into corresponding slots on both sides of the reinforcement positioning mesh frame 7.

[0039] It should be noted that the junctions of multiple foundation steel bars 6 and steel bar positioning mesh 7, as well as the cross intersections of multiple foundation steel bars 6, are connected by No. 8 tie wire to improve the stability of the steel bar skeleton structure.

[0040] Working principle: When in use, the foundation drawings are first optimized, and the reinforcement bars of the piles and the foundation reinforcement cage are simulated and installed using BIM technology. The position and spacing of the reinforcement bars that collide in the simulation are optimized.

[0041] Based on the spacing and diameter of the basic reinforcing bars 6, weld the reinforcing bar positioning calipers 1. Then, assemble the four reinforcing bar positioning calipers 1 into a "well"-shaped reinforcing bar positioning mesh frame 7. Then, weld the upper and lower reinforcing bar positioning mesh frames 7 together through connecting columns 4 to form a reinforcing bar skeleton structure. Install the basic reinforcing bars 6 in the grooves. The junctions of the basic reinforcing bars 6 and the reinforcing bar positioning mesh frame 7, as well as the cross points of the basic reinforcing bars 6, are firmly tied with No. 8 binding wire to prevent deformation and displacement of the reinforcing bars during transportation and hoisting.

[0042] The steel cage is moved by using the hoisting rope 5 to wrap around the intersection of the steel positioning mesh 7.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
