Description

Technical Field

[0001] The invention belongs to the technical field of assembled components of bridge and culvert engineering, and in particular relates to a one-piece tire frame used for tying steel bars of an assembled cover culvert wall. Background Art

[0002] In the assembly construction of bridges and culverts, culverts are usually prefabricated in factories, while for the prefabrication of the wall of the slab culvert, the steel bars must be installed by binding with a special cradle. The existing conventional cradles for the side wall steel bars of the slab culvert are generally horizontally bound, that is, the side wall is laid flat, which makes the side wall steel bar cradle occupy a large area, and can only bind and install the side wall steel bars of one section at a time, which reduces the construction efficiency and cannot meet the steel bar installation requirements of a large number of prefabricated slab culverts. Summary of the invention

[0003] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a one-piece cradle for tying the steel bars of the prefabricated cover culvert wall. The structure occupies little space, is simple to operate, and is highly efficient. It is a one-piece cradle structure for tying the steel bars of the prefabricated cover culvert wall.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A one-piece tire frame for tying steel bars of assembled cover culvert walls comprises a bracket and a positioning assembly, wherein the positioning assembly is evenly distributed on the bracket, the positioning assembly comprises a positioning sleeve and a positioning rod, the positioning sleeve is evenly distributed along the height direction of the bracket, and the positioning rod is inserted into the positioning sleeve.

[0006] Furthermore, the bracket includes a longitudinal portion and a transverse portion, both sides of the longitudinal portion are fixedly connected with positioning components, and one side of the transverse portion facing the longitudinal portion is fixedly connected with the positioning component.

[0007] Furthermore, the bracket includes a channel steel base, a channel steel column and an operating platform. The channel steel column is fixedly connected to the channel steel base, the operating platform is fixedly installed on the channel steel column, and the positioning sleeves are evenly distributed on the channel steel column.

[0008] Furthermore, the operating platform includes a platform plate and platform channel steel, the platform channel steel is fixedly connected to the channel steel column, and the platform plate is laid on the platform channel steel.

[0009] Furthermore, the bracket is connected with upper and lower channels, and the upper and lower channels are connected with the operating platform.

[0010] Furthermore, a handrail is fixedly connected to the channel steel column, and the handrail is located above the platform plate and the upper and lower passages.

[0011] Furthermore, an operating gap is provided between the railing and the platform plate, and between the upper and lower passages.

[0012] Furthermore, the positioning sleeve is a hollow steel pipe welded to the channel steel column.

[0013] Furthermore, the one-piece tire frame is used to tie the steel bars of the slab culvert wall, and the steel bars of the slab culvert wall include vertical steel bar rings and transverse steel bar rings, and the vertical steel bar rings are vertically fixedly connected with the transverse steel bar rings.

[0014] Furthermore, the vertical reinforcement ring is detachably connected to the positioning rod.

[0015] The beneficial effect of the present invention is that by laterally tying the side wall steel bars, the height during operation is effectively reduced, and at the same time the finished steel bars can be directly hoisted without turning them over, thereby preventing the steel bar skeleton from being deformed; tying the two side wall steel bars by a one-piece cradle not only saves site area but also improves efficiency; this cradle makes up for the problems of low efficiency and large footprint of existing steel bar cradles.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] A one-piece tire frame for tying steel bars of an assembled cover culvert wall comprises a bracket 1 and a positioning assembly 2. The positioning assembly 2 is evenly distributed on the bracket 1. The positioning assembly 2 comprises a positioning sleeve 3 and a positioning rod 4. The positioning sleeve 3 is evenly distributed along the height direction of the bracket 1. The positioning rod 4 is inserted into the positioning sleeve 3. The steel bars of the cover culvert wall are positioned and fixed by the positioning assembly 2, which is convenient for subsequent tying of the steel bars and improves the efficiency of steel bar tying.

[0023] The bracket 1 includes a longitudinal portion 5 and a transverse portion 6, and positioning components 2 are fixedly connected to both sides of the longitudinal portion 5, and the transverse portion 6 is fixedly connected to one side of the longitudinal portion 5 with a positioning component 2. Preferably, the bracket 1 is T-shaped or L-shaped, and the steel bars are positioned and fixed by the longitudinal portion 5 and the transverse portion 6 respectively, so as to improve the accuracy of the steel bar binding.

[0024] The bracket 1 includes a channel steel base 7, a channel steel column 8 and an operating platform 9. The channel steel column 8 is fixedly connected to the channel steel base 7, the operating platform 9 is fixedly installed on the channel steel column 8, and the positioning sleeves 3 are evenly distributed on the channel steel column 8.

[0025] The operating platform 9 includes a platform plate 10 and a platform channel steel 11. The platform channel steel 11 is fixedly connected to the channel steel column 8. The platform plate 10 is laid on the platform channel steel 11. The setting of the operating platform 9 facilitates workers to tie higher steel bars.

[0026] The bracket 1 is connected with an up-and-down channel 12 , which is connected to the operating platform 9 , so that the user can go up and down the operating platform 9 .

[0027] A handrail 12 is fixedly connected to the channel steel column 8, and the handrail 12 is located above the platform plate 10 and the upper and lower passages 12, so as to provide protection for the workers located on the operating platform and the upper and lower passages.

[0028] An operating gap 13 is provided between the railing 12 and the platform plate 10 and the upper and lower channels 12. The setting of the operating gap 13 makes it convenient for workers to tie the steel bars.

[0029] The positioning sleeve 3 is a hollow steel pipe, which is welded to the channel steel column 8 to facilitate the insertion of the positioning rod.
