Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a temporary road guardrail fixing support. Background Technology

[0002] At construction sites, in order to effectively distinguish between construction and temporary roads, it is usually necessary to demarcate clear area boundaries. Since the distance between guardrails is relatively long, reliable fixing measures must be taken to ensure functionality and safety, and effectively extend the service life of the guardrails.

[0003] Traditional road safety barriers typically use bolts to fix the posts to a strip of concrete at the base. This method requires continuously pouring an 18cm thick layer of concrete, leveling the site beforehand, using a large amount of concrete, and time for curing, thus increasing the cost of temporary facilities. While prefabricated temporary road safety barriers exist, they are easily moved and, when used on construction sites, cannot effectively ensure the safe implementation of construction zone demarcation, potentially creating safety hazards. Therefore, to ensure the effectiveness of construction zone demarcation, temporary road safety barriers must be fixed to the construction site to achieve the desired isolation effect.

[0004] To address these issues, construction techniques have been optimized by using precast concrete fixed supports embedded in the ground. Temporary road guardrails are then installed on top of these supports. After construction, the temporary road guardrails are removed, and the concrete fixed supports are then lifted out. While this approach solves the problems faced by existing technologies, it has several drawbacks: the precast concrete fixed supports have a low reuse rate and are essentially disposed of as construction waste after construction, thus reducing the indicators for green construction. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor reusability and low utilization rate of precast concrete fixed supports in existing site construction technology, and to provide a temporary road guardrail fixed support that is structurally sound, easy to install and use, and can be continuously reused.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a temporary road safety barrier support, comprising a protective cast-in-place shell, a reinforcing mesh structure, pre-embedded bolts, and barrier posts. The protective cast-in-place shell is a rectangular cylindrical structure with an open top. The reinforcing mesh structure is fixedly installed inside the protective cast-in-place shell. The pre-embedded bolts are welded to the reinforcing mesh structure inside the protective cast-in-place shell. Concrete is poured inside the protective cast-in-place shell, with the top surface of the concrete flush with the opening of the protective cast-in-place shell. The barrier posts are fixed to the concrete.

[0007] Preferably, the pre-embedded bolts are arranged in a vertical direction, with the roots of the pre-embedded bolts located below the opening of the protective casting shell and embedded in the concrete.

[0008] Preferably, a gasket is welded to the bottom of the railing post, and the gasket has a through hole that mates with a pre-embedded bolt. The gasket is fixedly installed on the concrete top surface by the pre-embedded bolt.

[0009] Preferably, the reinforcing mesh structure is arranged in a crisscross pattern from bottom to top along the inside of the protective cast-in-place shell.

[0010] Preferably, the length of the pre-embedded bolt is 10cm, the length embedded in the concrete is 8cm, and the exposed length is 2cm.

[0011] Preferably, the distance between the embedded bolt and the edge of the protective cast shell is at least 7cm.

[0012] Preferably, the pre-embedded bolt is equipped with a nut, and the railing post is fixed to the pre-embedded bolt by the nut.

[0013] Preferably, the protective casting shell is made of galvanized iron sheet or anti-aging plastic material, and the surface is coated with an anti-rust layer.

[0014] The present invention provides a temporary road guardrail fixing support, which has the following advantages: the temporary road guardrail fixing support provided by this application can meet the needs of the layout of temporary road guardrails on construction sites, is easy to construct, and is firmly fixed; the fixing support with a protective cast-in-place shell is easy to bury and remove, the surface is easy to clean, and the structure is firm and not easily damaged; it is easy to use and recycle, and can be reused multiple times, which not only reduces the generation of construction waste, but also reduces construction costs.
