Problems solved by technology

[0008] The technical problems to be solved are: the existing connection method of the horizontal joints of prefabricated wall panels requires high accuracy of steel bar alignment, difficult construction, complex grouting process, poor controllability of construction quality, and the shear performance and earthquake resistance of wall panels. Performance is greatly affected by connected nodes

Embodiment Construction

[0053] Such as Figure 1 to Figure 6 As shown, the present invention is based on a prefabricated building of prefabricated wall panels with built-in full-height bellows, including floor slabs 2 and prefabricated wall panels 1 arranged between adjacent floor slabs 2, upper prefabricated wall panels 12 and lower floor prefabricated wall panels 11 is connected through connecting piece 4.

[0054] A joint slurry layer 9 is arranged between the lower end surface of the prefabricated wall panel 1 and the upper surface of the floor slab 2. The thickness of the joint slurry layer 9 is not less than 3 mm, preferably 20 mm. The joint slurry can be laid in advance or the prefabricated wall panel 1. Set up the filling after it is in place. The joint slurry can be grouting material or sitting slurry.

[0055] Such as image 3 and Figure 4 As shown, the prefabricated wallboard 1 is pre-embedded with bellows 3, the number and location of the bellows 3 can be flexibly selected and adjuste...

Abstract

The invention relates to the technical field of prefabricated concrete wallboards and discloses an internal full-height corrugated pipe prefabricated wallboard based assembly type building and a construction method thereof. The internal full-height corrugated pipe prefabricated wallboard based assembly type building comprises floors and prefabricated wallboards arranged between adjacent floors; one upper layer prefabricated wallboard is connected with a lower layer prefabricated wallboard through a connection piece; each prefabricated wallboard is provided with a corrugated pipe in a pre-burying manner; each corrugated pipe is arranged in a full length in a height direction of the corresponding prefabricated wallboard and is formed with a vertical through hole in a hollow manner; each vertical through hole is internally provided with the corresponding connection piece; the top end of each connection piece extends upward out of the corresponding prefabricated wallboard; the corrugated pipes of the adjacent prefabricated wallboards are arranged in a one-to-one correspondence manner; the top end of each connection piece of the lower layer prefabricated wallboard penetrates through thecorresponding floor upward and extends into the vertical through hole of the corresponding upper layer prefabricated wallboard; and through hole slurry is poured into each vertical through hole. Theinternal full-height corrugated pipe prefabricated wallboard based assembly type building provided by the invention is low in construction difficulty, is convenient, rapid and efficient and is strongin construction quality controllability, reliable in transmission force between prefabricated concrete and late poured slurry and excellent in whole structure seismic performance.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete wall panels, in particular to a prefabricated building based on built-in full-height bellows prefabricated wall panels and a construction method thereof. Background technique [0002] At present, my country is vigorously promoting prefabricated concrete buildings. The existing prefabricated monolithic buildings have complex node connections and high economic costs, and are more suitable for high-rise prefabricated buildings. [0003] Commonly used horizontal patchwork connection methods mainly include sleeve grouting connection, grouting anchor grouting connection, bolt connection, etc., among which the sleeve grouting connection is the most widely used. [0004] Sleeve grouting connection, reserve a grouting sleeve at the bottom of the wall, insert steel bars after transporting to the site and pour special grouting material into the grouting sleeve, which has the same requirements ...
