Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a mortar-stopping device for adjusting a tie rod of an anti-collision guardrail template and a template segment. Background Art

[0002] At present, in the process of anti-collision guardrail construction, it is necessary to set a number of embedded steel bars, and then use two layers of anti-collision guardrail templates to clamp the embedded steel bars to form a stable casting cavity, and then pour concrete in the casting cavity to form the anti-collision guardrail; in which, in the process of using two layers of anti-collision guardrail templates to clamp the embedded steel bars, it is also necessary to set a fastening rod at the top of the two layers of anti-collision guardrail templates and set a tie rod at the bottom. Specifically, the tie rod needs to pass through the embedded steel bars, and both ends of the tie rod need to pass through the two layers of anti-collision guardrail templates.

[0003] In the related art, the two-layer anti-collision guardrail template has reserved installation holes in advance for the tension rods to pass through, and the installation holes need to have a slurry-stopping function to prevent leakage during the subsequent pouring of concrete.

[0004] However, in the actual installation process, the density of the embedded steel bars is relatively large, the one-time casting length of the anti-collision guardrail is relatively large, and the anti-collision guardrail template is a fixed steel template. After the anti-collision guardrail template is installed and the position is determined, the installation hole position of the tie rod is determined. When the tie rod is inserted, the tie rod often interferes with the high-density embedded steel bars, and the tie rod cannot be inserted normally. It is necessary to cut the embedded steel bars in multiple places and then insert the tie rods. Later, the embedded steel bars need to be welded and restored. The welding restoration is difficult, which greatly affects the construction quality of the guardrail, extends the construction period, and increases the construction cost. Summary of the invention
