Description

Technical Field

[0001] This utility model relates to a jig for processing precast straight wall steel cages, belonging to the field of precast culvert steel cage processing technology. Background Technology

[0002] In recent years, the comprehensive advancement of high-standard farmland construction has placed higher demands on the engineering quality and construction efficiency of supporting hydraulic structures, especially culverts. However, the traditional cast-in-place culvert construction method, due to its inherent limitations such as long cycle and poor controllability of on-site operation quality, has become a bottleneck restricting the progress of engineering construction. In contrast, prefabricated assembled culverts, relying on a factory-based production model, can significantly improve the integrity, durability, and consistency of the product structure thanks to their standardized manufacturing processes, intelligent production monitoring, precise mold systems, and controllable curing conditions.

[0003] In the existing prefabricated culvert production process, the jigs used for steel cage fabrication rely on manual adjustment of the main reinforcement bars for positioning, and then binding or welding them into a steel frame. This often lacks adjustability and cannot adapt to various culvert construction application scenarios, thus affecting production efficiency.

[0004] In summary, the existing prefabricated culvert production process suffers from technical problems due to the inability of the jigs used for steel cage fabrication to adapt to various culvert construction application scenarios, which affects production efficiency. Utility Model Content

[0005] This utility model aims to solve the technical problem that the jigs used for making steel cages in the existing prefabricated culvert production process cannot adapt to various culvert construction application scenarios, thus affecting production efficiency. Therefore, a jig for processing prefabricated straight wall steel cages is proposed, which includes a support base, a jig assembly, and a detachable assembly. The detachable assembly is detachably installed in the middle of the jig assembly, and the support base is set on the bottom side of the detachable assembly and the jig assembly.

[0006] The support base includes longitudinal square steel pipes and sleeves. Two longitudinal square steel pipes are arranged in parallel along the longitudinal direction. Sleeves arranged along the longitudinal direction are welded to both sides of the longitudinal square steel pipes. There are four sleeves.

[0007] The frame assembly includes an inverted T-shaped tube, a inclined beam assembly, a vertical connecting tube, and a transverse connecting tube. The inverted T-shaped tube includes a horizontally arranged bottom tube and a vertically arranged top tube. There are four sets of inverted T-shaped tubes. One end of the bottom tube of two sets of inverted T-shaped tubes is respectively fitted into the front side of two sleeves, and one end of the bottom tube of the other two sets of inverted T-shaped tubes is respectively fitted into the rear side of two other sleeves. The inclined beam assembly is located at the top of the inverted T-shaped tube. The vertical connecting tube is arranged vertically on the bottom side of the inclined beam assembly. A transverse connecting tube is fixedly connected between the vertical connecting tube and the top tube in the middle.

[0008] As another improvement of this utility model, the support base also includes horizontal steel pipes, two horizontal steel pipes are arranged horizontally on the top side of the vertical steel pipe, and the detachable component includes a wall opening steel frame, the foot of the wall opening steel frame is equipped with a U-shaped groove, and the wall opening steel frame is clamped to the top of the horizontal steel pipe through the U-shaped groove.

[0009] As another improvement of this utility model, the shape of the steel frame at the wall opening is rectangular.

[0010] As another improvement of this utility model, the shape of the steel frame at the wall opening is trapezoidal.

[0011] As another improvement of this utility model, the top of the wall opening steel frame is provided with multiple short steel bars along the longitudinal direction.

[0012] As another improvement of this utility model, the jig assembly also includes a handle steel bar, one end of which is connected to the vertical pipe and the other end of which is connected to the other end of the bottom pipe.

[0013] As another improvement of this utility model, positioning steel bars are welded on both the vertical connecting pipe and the horizontal connecting pipe.

[0014] As another improvement of this utility model, the inclined beam assembly includes a top beam tube, a bottom beam tube, and a bent tube, with the top beam tube and the bottom beam tube fixedly connected by the bent tube.

[0015] As another improvement of this utility model, positioning steel bars are welded on both the top beam pipe and the bottom beam pipe.

[0016] As another improvement of this utility model, two sleeves are set inside the two longitudinal square steel pipes, and two other sleeves are set outside the two longitudinal square steel pipes.

[0017] The beneficial effects of this utility model are:

[0018] By designing an inverted T-shaped tube that mates with the sleeve, the distance between the front and rear sides of the frame assembly can be adjusted, thus adapting to culvert walls of different thicknesses. By setting a detachable steel frame at the wall opening, this solution can be quickly applied to square and round culverts, facilitating production and improving production efficiency.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. In the description of this utility model, it should be noted that the positional relationships indicated by terms such as "horizontal," "vertical," and "longitudinal" are only based on the positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the components referred to have a specific orientation, or are constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Specific implementation method one: Combining Figures 1 to 6 This embodiment describes a jig for processing precast straight wall steel cages, characterized in that it includes a support base, a jig assembly, and a detachable assembly; the detachable assembly is detachably installed in the middle of the jig assembly, and the support base is disposed on the bottom side of the detachable assembly and the jig assembly.

[0027] The support base includes a longitudinal square steel pipe 1 and a sleeve 2. The two longitudinal square steel pipes 1 are arranged in parallel along the longitudinal direction. The sleeves 2 arranged along the longitudinal direction are welded to both sides of the longitudinal square steel pipe 1. There are four sleeves 2.

[0028] The tire frame assembly includes an inverted T-shaped tube 3, a inclined beam assembly 4, a vertical connecting tube 5, and a transverse connecting tube 6. The inverted T-shaped tube 3 includes a horizontally arranged bottom tube and a vertically arranged top tube. There are four sets of inverted T-shaped tubes 3. The bottom tube of two sets of inverted T-shaped tubes 3 is respectively fitted into the front side of two sleeves, and the bottom tube of the other two sets of inverted T-shaped tubes 3 is respectively fitted into the rear side of two other sleeves. The inclined beam assembly 4 is located at the top of the inverted T-shaped tubes 3. The vertical connecting tubes 5 are arranged vertically on the bottom side of the inclined beam assembly 4. The transverse connecting tubes 6 are fixedly connected between the vertical connecting tubes 5 and the top tubes at the middle. A total of 8 vertical connecting tubes are designed. There are 2 transverse connecting tubes, one at the front and one at the back. The transverse connecting tube on the front side of the tire frame connects the vertical connecting tube on the front side of the tire frame and the inverted T-shaped tube on the front side. The transverse connecting tube on the rear side of the tire frame connects the vertical connecting tube on the rear side of the tire frame and the inverted T-shaped tube on the rear side of the tire frame.

[0029] The distance between the planes containing the two sets of inverted T-shaped tubes on the front and the two sets on the rear is adjustable. A longitudinal limiting device is installed between the vertical connecting tubes at the ends of the inclined beam assembly. This device includes bolts, nuts, and limiting plates. The limiting plates are fixedly mounted on the vertical connecting tubes, and the bolts pass through them. The bolts are limited by tightening the nuts at both ends, thus limiting the distance between the planes containing the two sets of inverted T-shaped tubes on the front and the two sets on the rear. This increases adjustability, facilitates production and processing, and improves production efficiency.
