Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to an auxiliary device for concrete pouring of the side wall of a square culvert bottom slab. Background Art

[0002] For the cast-in-place concrete pouring of the side wall of a square culvert, it is usually to manually boost the conveying pipe of a pump truck to pour concrete into the side wall. However, the vertical steel bars of the side wall and the horizontal steel bars below the middle have all been tied up, and the chute or the string tube cannot extend into the inside of the steel bar framework for pouring. Therefore, not only will a large amount of concrete be scattered around the formwork, but also it will lead to the inability to be poured into a single shape at one time, seriously affecting the construction progress and the project quality.

[0003] After retrieval, there is an auxiliary pouring tool for a structural column with the publication number of CN215291525U in the prior art. This device fixes the pouring tool on the pouring formwork through a U-shaped fixture, and at the same time, guides the concrete into the pouring formwork through a chute placed on a connecting piece. However, the support structure of the pouring tool is single, and the U-shaped fixture may not be able to bear the weight of the concrete flowing into the pouring tool, resulting in a gap between the pouring tool and the pouring formwork, causing concrete leakage and even causing structural damage, affecting the progress of the pouring work.

[0004] After retrieval, there is an auxiliary pouring tool for a structural column with the publication number of CN 220451444U in the prior art. This device is fixed on the top of the formwork by clamping the side wall of the formwork installation hole through a clamping groove. Then, the bottom support plate and the baffles on both sides are used as the concrete pouring channels to pour the structural column. After the structural column is poured, the formwork and the pouring auxiliary tool on the formwork are removed, and the formwork and the pouring auxiliary tool are separated. This pouring auxiliary tool also has the problem of a single support structure, and the pouring auxiliary tool cannot adjust the length or position. When pouring a wider structural column, it can only be poured from the same position, which easily causes the concrete to accumulate, resulting in insufficient pouring and the phenomenon of inability to be poured at one time.

[0005] Therefore, an auxiliary device for concrete pouring of the side wall of a square culvert bottom slab is needed, which can prevent the generation of gaps between the auxiliary device and the pouring formwork to cause leakage, and can be spliced in multiple groups to extend the length of the auxiliary device, so that the concrete can be evenly poured into the pouring formwork.

[0028] The connecting mechanism 2 includes a connecting seat I 201, a connecting box I 202, a limiting block 203, a push rod 204, a gear 205, and a rotating seat 206. One side of the connecting seat I 201 is fixedly connected to one end of the deflector 1 through a boss, and on the other side, a pair of connecting seats II 2011 are symmetrically provided. One end of the insert block 2013 is rotatably connected to the connecting groove 2012 on the side wall of the connecting seat I 201. The connecting box I 202 is fixedly connected to the other end of the deflector 1.

At the same time, the slide rod 2031 pulls the limiting block 203. At this time, pull the connecting seat I 201 outwards to pull out the insert block 2013 from the connecting box I 202, and the rapid splitting of multiple groups of deflectors 1 can be completed.

After the pouring is completed, rotate the rotating seat 206 in the connecting mechanism 2 so that the connecting seat Ⅲ 2061 drives the roller 2062 to roll along the arc plate 2041, thereby jacking up the push rod 204, making the gear 205 drive the connecting rod 2051 to disengage from the connecting seat Ⅱ 2011.
