Embodiment Construction

[0016] The present invention is further illustrated below by specific examples.

[0017] In a certain housing construction project, the concrete label of the column is C45, and the concrete label of the beam and slab is C35. The concrete pouring operation is carried out by the method mentioned above, and the pouring quality is very good.

[0018] Such as figure 1 , figure 2 as shown,

[0019] The implementation steps of the construction method are as follows:

[0020] The first step is to bind the column reinforcement (column stirrup 1, column main reinforcement 2) until it is 1m higher than the upper surface of the upper floor;

[0021] The second step is to set up the column formwork and support system to the bottom of the upper beam;

[0022] The third step is to set up the steel pipe support system and formwork for the scaffolding of the upper beam and slab, and bind the beam reinforcement (beam stirrup 3, beam main reinforcement 4);

[0023] The fourth step is to in...

Abstract

The invention relates to a method for pouring different grades of concrete to beam column junctions. The method includes the following steps: a step 1, binding column reinforcing steel bars till the height is higher than an upper surface of an upper floor; a step 2, establishing column plates and a support system on the bottoms of upper beams; a step 3, establishing a scaffold steel pipe support system and templates of upper beams and plates, and binding beam reinforcing steel bars; a step 4, inserting a row of isolation reinforcing steel bars in beams on the column beam junctions, wherein the isolation reinforcing steel bars are higher than the upper surface of the upper floor; a step 5, pouring column high grade concrete to the top surfaces of the isolation reinforcing steel bars with vibrating and compacting the concrete; and a step 6, pouring low grade beam plate concrete before initial set of column top concrete, pulling out of the isolation reinforcing steel bars, performing vibrating and compacting, and completing the pouring work of the concrete. The construction method can use local materials which are low in cost and can be reused; and the construction method is low in construction technological difficulty, can save workers, is high in operability, is good in construction effect, and can separate beam and column concrete.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for pouring concrete with different labels at beam-column nodes. Background technique [0002] In concrete structures, the columns mainly bear the load transmitted by the beams. Due to the different loads, at the same column-beam joint position, the concrete grade of the column is often one or several grades higher than that of the beam. At present, in the concrete pouring process, the concrete of the high-grade columns is generally poured first, and then the concrete of the low-grade beams is poured after being vibrated and compacted. At the joint position of the column and the beam, the concrete of the column will inevitably flow into the beam, and a construction joint will be formed between different grades of concrete in the beam, which will affect the construction quality of the beam. [0003] After searching the existing literature, it is found that the curre...
