Novel pouring gun head for silicone joint material of concrete expansion joint

Abstract

The invention relates to a novel pouring gun head for a silicone joint material of a concrete expansion joint. The novel pouring gun head for the silicone joint material of the concrete expansion joint comprises a pouring head and a base, wherein the pouring head is connected with the base, and the base is connected with a glue gun. The novel pouring gun head has the characteristics of being uniform in pouring and being difficultly mingled with bubbles; pouring and surface concave scrapping of a joint material can be simultaneously realized, and the pouring quality and the pouring efficiency are remarkably improved. The pouring head is connected with the base by adopting a bayonet and the base is connected with the glue gun by adopting a bayonet, thus the novel pouring gun head is easy to disassemble, brings convenience in immediately cleaning a glue material inside, and can be repeatedly used. The problems of poor construction quality, low pouring efficiency, large labor intensity and the like of an existing joint material are solved, and the novel pouring gun head is suitable for constructing joint materials in the fields of high-speed railways, expressways, airfield runways and the like.

Description

technical field [0001] The invention relates to a novel concrete expansion joint silicone caulking material pouring gun head, in particular to a silicone caulking material pouring gun head for concrete expansion joints such as high-speed railway ballastless tracks, expressways and airport runways. Background technique [0002] Expansion joint design has been widely used in long-line continuous pouring concrete structures. During the caulking construction of concrete expansion joints, manual pouring is often used. The pouring equipment is a single-component manual glue gun, and the head of the pouring gun is conical. Two people are required to cooperate during construction and pouring. One person is responsible for filling the caulking material with a glue gun, and the other is responsible for cleaning the excess caulking material on both sides of the expansion joint after filling, and scraping the surface of the caulking material into a concave surface to prevent the caulkin...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing perfusion gun head is conical, which needs to be cut on site, which is time-consuming and laborious;

[0005] 2. The diameter of the muzzle is too small, the pouring speed is slow, and it is easy to contain air bubbles in the glue layer after pouring, which cannot meet the requirements of rapid construction and affects the construction quality and construction efficiency;

[0006] 3. The pouring of caulking material and surface scraping cannot be completed simultaneously, and more than two people are required to cooperate in construction;

[0007] 4. When pouring, the manual glue gun needs to be held all the way, unable to use force, and the labor intensity is high;

[0008] 5. After use, the gun head is difficult to disassemble, and the excess rubber inside the gun head is even more difficult to clean up. The gun head cannot be reused, and the overall cost is high
