Problems solved by technology

However, due to the existence of the concrete sash, the rigidity of the multi-ribbed composite wall panel is very high. During the earthquake, the main frame is subjected to the huge support force of the wall panel, and stress concentration often occurs at the end of the column, the bottom of the column and the joint area. , it is easy to lead to premature failure of the above parts, which will have an adverse effect on the structure's seismic resistance

example 1

[0026] 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 300*500mm; the concrete strength grade is C30; Design Code" (GB50010-2002) and "Code for Seismic Design of Buildings" (GB50011-2010). see Figure 3-6 , using small concrete solid blocks to construct damping and anti-seismic filling walls on site, and its structure is as follows:

[0027] The entire masonry 1 is set in the space surrounded by the left frame column 6, the right frame column 6', the upper frame beam 7 and the lower frame beam 7', the thickness is 240 mm, and it is vertically built by three masonry units 2, Between the upper and lower two masonry units 2, and between the first masonry unit 2 counting from the upper frame beam 7 and the upper frame beam 7, and between the third masonry unit 2 and the lower frame beam 7', respectively set There is a viscoelastic la...

example 2

[0031] The damping and anti-seismic filling wall described in this example adopts prefabricated concrete wall panels, and the structure and construction method are the same as in Example 1 except for the following.

[0032] see Figure 7, the whole masonry 1 is vertically built by four masonry units 2, between the upper and lower two masonry units 2, and between the first masonry unit 2 counted from the upper frame beam 7 and the upper frame beam 7 and the second A viscoelastic layer 3 with a thickness of 5 cm formed by pouring asphalt is provided between the four masonry units 2 and the lower frame beam 7'. Among them, one end of the first and third masonry unit 2 counted from the upper frame beam 7 is connected with the left frame column 6 by anchoring steel bars 4, and a 4cm gap is reserved between the other end and the right frame column 6′. Wide gap 5; one end of the second and fourth masonry unit 2 counted from the upper frame beam 7 is connected with the right frame co...

Abstract

The invention relates to a damped anti-seismic filling wallboard for a framework. The filling wallboard has a brickwork (1) which is filled in a space defined by framework beams and columns. The filling wallboard is characterized in that the brickwork (1) is built from multiple brickwork units (2); a viscoelastic layer (3) is respectively arranged between every two adjacent brickwork units (2), between the brickwork at the top layer and an upper framework beam (7), and between the brickwork unit (2) at the bottom layer and a lower framework beam (7'); and one end of one of two adjacent brickwork units (2) and a left framework column (6) are fixedly connected into a whole by a steel bar (4), and a gap (5) is reserved between the other end of the brickwork unit (2) and a right framework column (6'), one end of the other brickwork unit (2) and the right framework column (6') are connected into a whole by a steel bar (4) and a gap (5) is reserved between the other end of the other brickwork unit (2) and the left framework column (6). The damped anti-seismic filling wallboard in the invention can reduce the earthquake response of the structure and protect the safety of the wall body.

Description

technical field [0001] The present invention relates to walls of buildings, in particular to walls of frame structures, and in particular to the construction of anti-seismic filled walls. Background technique [0002] The frame structure is widely used in buildings such as multi-storey residences, factories, shops, office buildings, hospitals, teaching buildings and hotels because of its advantages of flexible layout and large interior space. The frame structure generally builds infill walls for functional division and external enclosure. Because the tensile strength of the blocks and mortar is not high, the bonding strength of the interface between the mortar and the blocks is also low; the early rigidity of the wall is large, and under the action of the earthquake, it bears a large earthquake. Therefore, when the earthquake occurs, , the failure of the filling wall is earlier and more serious. The research on the damage of frame structure buildings after the Wenchuan Ear...
