Description

Concrete terrace crack control block

Technical Field

The utility model relates to the technical field of building construction, in particular to a concrete terrace crack control block.

Background

In recent years, the construction industry of China has been unprecedented developed, the concrete terrace is visible everywhere, but crack control is always the quality common problem of concrete terrace construction, the concrete terrace crack control is not in place, the crack of terrace will lead to whole surface course to produce reflection crack, not only influence impression and life, the maintenance degree of difficulty is big and effect is relatively poor simultaneously, influence the cause of concrete terrace crack is many, and the concrete terrace crack problem is the engineering difficult problem of recognition, because the construction characteristics of the constituent material and the self of concrete, make terrace crack hardly eliminate completely.

Through a large number of investigation researches, the occurrence frequency of concrete terrace cracks at the external corner positions of protruding terrace structures such as wall posts, equipment foundations and the like is extremely high, and the cracks are controlled by adopting a proper method, so that the cracks of the concrete terrace are greatly reduced, and a concrete terrace crack control block is needed.

Disclosure of Invention

The utility model aims to provide a concrete terrace crack control block which is simple to operate, simple in manufacturing process and not easy to damage, and stress at external corners and the like can be uniformly dispersed and transferred to all directions of a concrete ground, so that cracks at the external corners of protruding terrace structures of wall posts, equipment foundations and the like are reduced, and the problems in the background art are solved.

The technical scheme of the utility model is as follows: the utility model provides a concrete terrace crack control block, includes the cylinder, the four corners of cylinder all is provided with crack control block, four the removal groove has all been seted up at the inboard both ends of crack control block, and the inboard of four crack control blocks is all symmetrically fixed with two installation blocks, and is a plurality of one side of installation block all is fixed with the spring, and is a plurality of the other end of spring all is fixed with the fixed plate.

Preferably, the four crack control blocks are all annular cylinders with an inner diameter of 20 mm and an outer diameter of 80 mm.

Preferably, the opening angles of the four crack control blocks are all 90 degrees.

Preferably, a plurality of reinforcing ribs are fixed inside the four crack control blocks.

Preferably, rubber sleeves are sleeved on the outer sides of the four fixing plates.

Compared with the prior art, the concrete terrace crack control block provided by the utility model has the following improvements and advantages:

the utility model has novel design and ingenious structure, and the crack control block is fixed with the external corners at the bottoms of the wall column, the equipment foundation and the like, so that the stress concentrated at the external corners is uniformly dispersed and transferred to all directions of the concrete terrace, and the cracks at the external corners of the protruding terrace structures of the wall column, the equipment foundation and the like are eliminated or reduced by a stress reduction method, and the fixing and attaching effects are better by arranging the springs and the fixing plates.
