Embodiment 1

[0045] A construction method for a hollow floor slab, comprising the following steps:

[0046] Step 1, construction preparation;

[0047] Step 2, formwork installation, calculate the formwork support system of the gypsum filling box, in which, the saturated bulk density of the gypsum filling box must be fully considered during the calculation process, and the support system should be erected strictly according to the calculation results. Carry out two-way arching; encrypt the supporting distance of the steel pipe frame under the concealed beam and column cap, and encrypt the supporting distance of the steel pipe frame under the floor according to the special construction plan;

[0048] Step 3, measure and set out the line, set out the line according to the layout drawing, release the position line of the rib beam, and determine the installation position of the gypsum filling box;

[0049] Step 4, steel bar binding, steel bar installation according to the construction drawing,...

Embodiment 2

[0064] In order to make the technical solution in this application more complete and detailed, further supplementary explanations are made on the basis of the above-mentioned embodiment 1, so that the technical means used in this application are disclosed more fully, wherein the technical characteristics of the supplementary part are: In step 1 above, the construction preparation is divided into the following processes:

[0065] S1, according to the size of the drawing and the model specification of the gypsum filling box, prepare a material entry plan and entrust a professional manufacturer to produce it;

[0066] S2. Organize construction technicians to conduct targeted learning, conduct technical and safety disclosures for teams of different types of work, and prepare for labor;

[0067] S3, before construction, divide a special material site on site, and process the site according to the relevant regulations on the stacking of gypsum filling boxes;

[0068] S4. After the ...

Abstract

The invention discloses a construction method of a hollow floor slab. The construction method of the hollow floor slab comprises the following steps of 1, construction preparation; 2, formwork installation; 3, surveying and laying-out; 4, steel bar binding; 5, water and electricity line pre-embedment; 6, information of a gypsum filling box; 7, installation of plate steel bars; and 8, concrete pouring and vibrating. According to the construction method, a gypsum filling box dense rib floor structure system is adopted, the long-span structure space clear height can be increased, and the buildingspace is open and light in weight. Meanwhile, the hollow floor slab has the remarkable advantages that identical bidirectional stress force and transfer force, small deflection deformation, good shear and torsion properties, good crack resistance and earthquake resistance and the like, the overall performance of a floor system is improved, the thickness of the floor system is effectively reduced,and the dead weight of the structure is reduced.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a hollow floor slab. Background technique [0002] A hollow-core slab is a prefabricated slab. One or several total longitudinal holes are set inside to save material and reduce weight. Usually made of prestressed concrete, its size depends on the size of the house bay and the capacity of the hoisting machinery. The holes in the board are good for sound insulation and heat insulation. [0003] At present, there is another kind of hollow box floor slab in construction. Small concrete hollow boxes are used as the unit body. The boxes are connected with steel bars, and concrete is poured in the gaps. This technology saves materials and the weight of the floor slab is lighter, and it is mostly used in high-rise buildings. [0004] However, in the construction process of the existing hollow-core slabs, there are often restrictions on the height of the large-span bui...
