Problems solved by technology

In the subsequent concrete pouring and vibrating process, if the spot welding method is used, the steel bars will be displaced, and the embedded parts will be displaced simultaneously; if the binding installation is used, the horizontal and vertical displacements of the embedded parts will be different to varying degrees due to the weak binding. Displacement, which leads to the installation quality of the embedded parts cannot meet the construction requirements, causing great hidden dangers to the subsequent guardrail installation, which is not expected by those skilled in the art

Embodiment Construction

[0028] The structure of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended as a limitation of the present invention.

[0029] Such as Figure 1~5 As shown, the present invention discloses a fixing device for the embedded part of the anti-collision barrier. The fixing device is applied on the formwork 6 of the anti-collision barrier to fix the embedded part 7. A plurality of pre-embedded screws on the pre-embedded steel plate; yes, the fixing device includes a positioning bolt 1, a first nut 4, a second nut 3, a third nut 8 and a positioning steel plate 5, and the first nut 4 and the pre-embedded The screw rods are matched, and the second nut 3 and the third nut 8 are all matched with the positioning bolt 1 (the second nut 3 and the third nut 8 can be the same nut); the two sides of the above-mentioned positioning steel plate 5 are all provided with positioning holes 52 The middle...

Abstract

The invention relates to the technical field of building construction, in particular to a fixing device and construction method for pre-embedded parts of an anti-collision guardrail. Positioning holescorresponding to pre-embedded screws one to one are formed in the middle of a positioning steel plate, mounting holes corresponding to positioning bolts are formed in the two sides of the positioningsteel plate, thus the pre-embedded parts can be prefixed onto the positioning steel plate through nuts, the positioning steel plate is fixed to a top cross rib of an anti-collision wall mold plate through the positioning bolts and the nuts to fix the pre-embedded parts to the mounting position, thus the mold plate can be used as a support system, the condition that during vibrating of concrete, the pre-embedded parts produce displacement, and consequently subsequent mounting of the guardrail is affected is avoided, and then the mounting and construction quality of the pre-embedded parts of the anti-collision guardrail is improved; and through first nuts, the elevation and plane position of the pre-embedded parts can be fine-adjusted, thus positioning of the pre-embedded parts is accurate,then the mounting precision of the pre-embedded parts of the anti-collision guardrail is improved, and the quality assurance is provided for subsequent guardrail mounting.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a fixing device and a construction method for embedded parts of anti-collision guardrails. Background technique [0002] With the continuous growth of my country's national economy and the development of urban infrastructure construction, cities and highway bridges, underpass tunnels, viaducts and other projects are undergoing large-scale construction. If the guardrail project is not installed smoothly, it will affect the appearance quality of the anti-collision guardrail and directly affect the appearance of the city. Before the installation of the guardrail, it is necessary to reserve the embedded parts of the guardrail in advance on the top of the anti-collision wall. The installation quality of the embedded parts directly affects the quality of the subsequent guardrail installation. Therefore, higher requirements are put forward for the installation of the embed...
