Abstract

An integral assembly method of a precast concrete box structure building comprises the steps of: 1) precasting and decorating concrete box bodies, 2) horizontally connecting boxes in a concrete cast-in-place belt manner, 3) vertically connecting the boxes in a sleeve connecting manner, and 4) forming the whole building, and supplementing partial decoration, wherein each concrete box is lack of one or two side faces and a bottom face. The method has the significant advantages that the method reduces turnover of construction materials, achieves standard factory manufacturing of the building, improves house quality and construction efficiency, shortens a cycle, reduces manpower, is environment-friendly, energy-saving and water-saving, reduces formation of concrete cracks and increases an assembly rate of the building.

Description

A kind of monolithic assembly method of precast concrete box structure building

Technical field

The invention belongs to the monolithic assembly method technical field of a kind of precast concrete box structure building.

Background technology

Current China builds the mode in house also mainly based on wet trade, have waste of material, winter construction difficulty, the ash and other building wastes are more, dust from construction sites affects urban air-quality, construction quality is difficult to obtain effective guarantee of landing, finishing may destroy the problems such as original structure.

The prefabricated concrete structure form of current domestic appearance has two kinds substantially.The first form is: form monolithic architecture by the mode of cast-in-situ concrete with dry wall, prefabricated post, prefabricated superimposed sheet for unit.Although this mode decreases the impact of wet trade, prefabrication and assembly construction rate is still lower.The second form is: prefabricated whole concrete box, solves box connection up and down, to form monolithic architecture by the mode of Weak link.Although this mode substantially increases prefabrication and assembly construction rate, whether house meets the demands and there is no method and determine, cannot promote.

Summary of the invention

Object of the present invention is just in order to overcome defect that above-mentioned prior art exists and not enough and provide a kind of assembly rate both having improved building, the monolithic assembly method of a kind of precast concrete box structure building making again house be met.

The object of the invention is to realize by following technical solution.

A monolithic assembly method for precast concrete box structure building, the present invention is characterised in that: step is:

1), prefabricated and fit up concrete casing; Wherein concrete chest lacks a side or two sides, lacks bottom surface;

2) level connection joint of prefabricated panel between casing, is completed in the mode of concrete cast-in-situ band; Wherein, cast-in-situ concrete joint pin is located between two blocks of wallboards, the connecting end surface of wallboard is provided with matsurface or toothed surfaces, cast-in-situ concrete joint pin is longitudinally provided with longitudinal reinforcement, anchor ring is provided with in cast-in-situ concrete joint pin, stirrup is provided with from top to bottom, then cast-in-situ concrete level connection joint two wallboard on longitudinal on whole cast-in-situ concrete joint pin;

3), the vertical connection between casing is completed in the mode of sleeve connection; Wherein, be provided with cast-in-place collar tie beam, cast-in-place collar tie beam has keyway or matsurface between upper and lower two wallboards, upper and lower two wallboards adopt vertical dowel to be connected by slurry anchor sleeve connection or slurry anchor overlap joint;

4), form whole building, supplementary portion divides finishing.

beneficial effect of the present invention and being compared with the prior art (outstanding advantages):

1, a large amount of minimizing construction circulation material;

2, building standard chemical plant can be realized manufacture, improve housing quality, improve efficiency of construction, reduce the cycle, reduce artificial;

3, environmental protection and energy saving water saving (reducing the building wastes such as dust, noise, concrete block);

4, can industrial waste be utilized, turn waste into wealth, economize the land resource and other material;

5, decorate disposable putting in place, prevent pollution and the waste of secondary decoration;

6, the formation of distress in concrete is reduced.

One aspect of the present invention improves the assembly rate of building, and house also can be met on the other hand, without the need to adopting superimposed sheet, compared with common prefabricated concrete structure, improves prefabrication and assembly construction rate.Connect chest by the mode of ater-casting, compared with box-shaped structure, improve house.

Detailed description of the invention

A monolithic assembly method for precast concrete box structure building, the present invention is characterised in that: step is:

1), prefabricated and fit up concrete casing; Wherein concrete chest lacks a side or two sides, lacks bottom surface;

2) level connection joint of prefabricated panel between casing, is completed in the mode of concrete cast-in-situ band; Wherein, cast-in-situ concrete joint pin is located between two blocks of wallboards, the connecting end surface of wallboard is provided with matsurface or toothed surfaces, cast-in-situ concrete joint pin is longitudinally provided with longitudinal reinforcement, anchor ring is provided with in cast-in-situ concrete joint pin, stirrup is provided with from top to bottom, then cast-in-situ concrete level connection joint two wallboard on longitudinal on whole cast-in-situ concrete joint pin;

3), the vertical connection between casing is completed in the mode of sleeve connection; Wherein, be provided with cast-in-place collar tie beam, cast-in-place collar tie beam has keyway or matsurface between upper and lower two wallboards, upper and lower two wallboards adopt vertical dowel to be connected by slurry anchor sleeve connection or slurry anchor overlap joint;

4), form whole building, supplementary portion divides finishing.
