Problems solved by technology

However, the construction of the gypsum mold box used as the inner mold in the cast-in-place floor slab is relatively difficult
Through the inspection of the BZS cavity composite floor slab construction site that has been completed and is under construction, it is found that the molding condition is not ideal, and it is easy to produce honeycomb pockmarks and floating displacement of the mold box, which affects the appearance
This is unacceptable to both Party A and the construction party. Therefore, it is an important task to find a construction method to solve the phenomenon of honeycomb pitting and floating displacement of the mold box. Problems with great engineering application value

Embodiment 1

[0031] (1) According to the structural design of the BZS cavity composite floor, the size of the BZS cavity composite mold box provided is 580mm×580mm×200mm; the size of the cubic concrete standard block provided is 60mm×60mm×60mm, and the block is placed on the BZS cavity The four corners under the cavity compound mold box support the mold box to facilitate the flow of concrete into the bottom of the mold box, ensure that the concrete can be vibrated and compacted, and avoid holes, honeycombs, and exposed tendon defects in the concrete at the bottom of the mold box.

[0032] (2) Since the BZS cavity composite mold box is light in weight and has good water absorption, the mason is required to water it one day in advance before pouring, and then water the mold box before pouring concrete to increase the quality and prevent floating.

[0033] (3) After the BZS cavity composite mold box is installed, the anti-floating steel bars are tied according to the design requirements, and t...

Embodiment 2

[0037] (1) According to the construction method of the BZS cavity composite floor, prepare the BZS cavity composite mold box, carry out construction preparations, and carry out construction according to the steps of Example 1;

[0038] (2) Concretely analyze and control the new and difficult points in the construction process:

[0039] 1) When pouring and tamping, the construction worker controls the size of the fine concrete aggregate and the slump. The size of the aggregate should not be greater than 30mm, and the slump must be controlled between 180mm and 210mm;

[0040] 2) Unloading workers must put concrete between the ribs of the mold box and prevent excessive accumulation at one time;

[0041] 3) Pouring and compacting must be carried out in layers. The method of skipping ribs is adopted, combined with high-efficiency vibration, and the vibration time is sufficient. Only when there is concrete overflow on the other side of the mold box can the next place be vibrated.

Abstract

A BZS cavity composite floor structure and a construction method thereof are provided. The BZS cavity composite floor structure comprises filling mold boxes, a template, cushion blocks, stressed steelbars and distributed steel bars. At least one steel wire hole is reserved in each filling mold box for steel wires to penetrate and be fixed. The stressed steel bars are respectively arranged in theupper and lower parts of the filling mold boxes. The distributed steel bars are arranged between the filling mold boxes. After concrete is poured, the stressed steel bars and the distributed steel bars form the template. The filling mold boxes are permanently buried in a concrete floor as internal molds. The filling mold boxes are glass fiber reinforced gypsum cavity molds, namely, BZS mold boxes.Steel wire holes are reserved in the BZS mold boxes for steel wires to penetrate and be fixed. The cushion blocks of the same height are placed under the four corners of each BZS mold box. By using the BZS cavity composite floor structure, the amount of concrete used in the floor can be reduced by 10-30%, the amount of steel used in the floor can be reduced by 20-30%, and the total construction period can be shortened by 10-15%. The comprehensive cost is significantly reduced, and the comprehensive engineering cost is 5-15% lower than that of buildings adopting an ordinary floor structure.

Description

technical field [0001] The invention relates to a BZS cavity composite floor structure and a construction method, belonging to the technical field of civil construction. Background technique [0002] The cavity composite floor slab is a composite cavity floor slab formed by using the prefabricated filling mold box as the inner mold and filling it in the concrete floor slab. The filling mold box is prefabricated with light refractory materials, and it plays the role of the inner mold during construction. The construction is completed Then stay in the floor slab and form a cavity composite floor slab with the reinforced concrete floor slab structure. BZS mold box is a prefabricated component, which is made of building gypsum as the main material and reinforced with glass fiber (BZS mold box for short). Building gypsum has been tested by the environmental protection department and identified as an "unrestricted" excellent building material. However, the construction of the gy...
