Description

Technical Field

[0001] The invention belongs to the field of bridge engineering, and particularly relates to the construction of cast-in-place beams of a disc-type ground-to-ceiling full-span bracket, which is a bracket working layer edge protection guardrail structure. Background Art

[0002] At present, with the development of urbanization and infrastructure construction, a large number of high-height viaducts and interchange flyovers are being built. As bowl-hook brackets and fastener brackets are gradually restricted or eliminated, disc-hook brackets or Bailey beams + disc-hook brackets are mostly used in cast-in-place beam construction. In order to ensure the safety of operations, it is necessary to set up edge protection guardrails on the working layer. The guardrails must meet the requirements of a bearing capacity of not less than 1000N and a height of not less than 1.5m. There are two methods for setting up existing edge protection guardrails. One is to use fastener-type steel pipes to set up edge protection guardrails at the outermost working layer of the bracket. The guardrail uprights are connected to the crossbar of the disc-hook bracket through fasteners, and the guardrail crossbars are set up with fastener steel pipes. This method requires additional fastener steel pipe materials in the disc-type bracket, and the length of the guardrail upright is shorter than the standard length of the fastener steel pipe, so it needs to be cut before use, and the residual value of the material is low. Secondly, an additional row of ground-based disc-type brackets is set up on the outside of the disc-type bracket, which requires a large amount of disc-type bracket engineering work, and the hardened width of the bracket foundation also needs to be widened, which greatly increases the cost, has high construction cost, and is more troublesome to construct. Utility Model Content

[0003] The utility model aims to provide an economical and reliable disc buckle bracket edge protection guardrail structure, which is erected using existing standard disc buckle rods, has a simple erection method, consumes less disc buckle bracket material, and reduces construction costs.

[0004] The technical solution of the utility model is:

[0005] A disc-shaped bracket edge protection guardrail structure, which is composed of a cross bar arranged at the first and third connection plates from top to bottom outside the disc-shaped bracket working layer, namely an upper cantilever cross bar and a lower cantilever cross bar, a long vertical bar is cantilevered outside the upper cantilever cross bar and the lower cantilever cross bar, namely a cantilever guardrail vertical bar, a cantilever diagonal bar is arranged at the sixth connection plate from top to bottom outside the working layer of the disc-shaped bracket, and is connected to the lowest connection plate of the cantilever guardrail vertical bar, the lower cantilever cross bar and the cantilever diagonal bar form a triangular structure, the upper cantilever cross bar and the lower cantilever cross bar, the cantilever diagonal bar and the cantilever guardrail vertical bar are mutually connected to form a cantilever frame, and the cantilever frames are connected along the longitudinal direction of the disc-shaped bracket to form an edge protection guardrail.

[0006] Furthermore, the lengths of the upper cantilevered crossbar and the lower cantilevered crossbar are both 60 cm.

[0007] Furthermore, the length of the cantilever guardrail upright is 300 cm.

[0008] Positive effects of the utility model:

[0009] The utility model of the buckle bracket edge protection guardrail structure is erected using conventional buckle standard rods, without the need for additional components. It is cantilevered and erected outside the bracket working layer using a cantilever structure, and does not need to be erected on the ground, reducing the amount of engineering work for the buckle bracket erection and the bracket foundation hardening. The erection method is simple, and the buckle bracket material consumption is less, which simplifies the construction workload and reduces the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS
