Problems solved by technology

Light-weight panels have been developed following the requirements of the national construction industrialization, but there are still two problems: (1) the use of pure concrete wall panels contributes too much to the lateral stiffness of the structure, and there is no pre-preparation around the wall panels. Leaving seams makes the wall panels prone to damage during earthquakes; (2) The seismic performance of domestic partition wall panels is still unclear, and the research on its response in earthquakes is not very sufficient. Scholars at home and abroad have conducted a large number of wall panels. However, the research is mainly from the perspective of "hard resistance" to improve the seismic performance of wall panels, and there are few studies on the use of energy dissipation and shock absorption technology to improve the seismic performance of wall panels
[0004] The invention patent application with the publication number CN102268900A discloses "a damping and anti-seismic filling wallboard for frame structures". Although the lateral stiffness of the filling wallboard is significantly reduced and the damage caused by earthquakes is significantly reduced, it still has the following deficiencies: : 1. Only rely on the viscoelastic layer set between two adjacent masonry units, between the masonry unit on the uppermost layer and the upper frame beam, and between the masonry unit on the lowermost layer and the lower frame beam to provide damping. Therefore, the ability to absorb and dissipate seismic energy is very limited; 2, because the described masonry is vertically piled up by several masonry units, it is not convenient to install doors or windows on the infill wall, once the installed door or window spans two If the masonry unit is more than 1 block, its damping and anti-seismic will disappear; 3. Since one end of the masonry unit and the frame column are fixed and connected as a whole, it is not convenient for on-site assembly and construction

example 1

[0021] This example is a concrete frame with a span of 4200mm and a floor height of 3300mm. The cross-sectional size of the frame column is 500mm×500mm, and the cross-sectional size of the frame beam is 300mm×500mm; the concrete strength grade is C30; Design Code" (GB50010-2010) and "Code for Seismic Design of Buildings" (GB50011-2010).

[0022] see Figure 1~3 , the energy-dissipating and shock-absorbing filling wallboard in this example has a masonry that is filled in the space enclosed by the upper frame beam 1, the lower frame beam 1-1 and the frame columns 2 on both sides; The shock-absorbing concrete slabs 3 respectively fixed on the upper frame beam 1 and the lower frame beam 1-1 and the flexible waterproof filler polystyrene in the structural joints 6 between the shock-absorbing concrete slab 3 and the frame columns 2 on both sides Ethylene foam composition;

example 2

[0027] see Figure 4 and 5 , the energy-dissipating riveting member 4 described in this example is three rows of steel rods vertically passing through the insulation layer 7, and the number of each row is 7 pieces. The middle part of the steel rods is provided with an annular groove, and the bottom of the groove is arc-shaped; The two ends of the steel rod are respectively riveted to the outer surfaces of the two panels through steel plates 4-1. The implementation method of this example except the above is the same as Example 1.

Abstract

The invention discloses a prefabricated energy dissipation and shock absorption filled wallboard which is provided with a masonry. A space enclosed by frame beams and columns is filled with the masonry; the masonry comprises a shock absorption concrete board and flexible waterproof fillers, the upper edge and the lower edge of the shock absorption concrete board are respectively fixed onto the frame beams, and the flexible waterproof fillers are arranged in structural joints between the shock absorption concrete board and the two side frame columns; the shock absorption concrete board comprises a face board with an inverted-L-shaped vertical section and a face board with a J-shaped vertical section, the two face boards coincide with each other, and a closed space with a rectangular vertical section is enclosed by the two face boards and is filled with flexible waterproof fillers; slip layers with waterproof rolls are arranged between the transverse edges of the inverted-L-shaped face board and the upper end surface of the J-shaped face board and between the transverse edges of the J-shaped face board and the lower end surface of the inverted-L-shaped face board; two to three rows of rod-shaped energy consuming riveting components are transversely penetratingly arranged on the shock absorption concrete board and are positioned in a belly of the closed space, and two ends of each energy consuming riveting component are respectively riveted on the two face boards.

Description

technical field [0001] The present invention relates to walls of buildings, in particular to walls of frame construction, and in particular to the construction of infill walls. Background technique [0002] Since my country issued the "National New Urbanization Plan" (2014-2020) and the "Twelfth Five-Year Plan" put forward the goal of affordable housing construction, the application of prefabricated concrete structures in urban buildings (medium and low-rise buildings) has been given great significance , the research on prefabricated concrete structures began to heat up gradually. Moreover, at this stage, my country's multi-level needs for promoting new urbanization and deepening reforms also urgently require further research and development of prefabricated concrete structures. [0003] In the existing prefabricated concrete structures, masonry infill walls and lightweight wall panels are the most widely used enclosure components, but in previous earthquakes, masonry infill...
