Abstract
The utility model relates to a shear wall partially equipped with oblique rebars, belonging to the technical field of concrete shear walls. The shear wall is a concrete shear wall, and a vertically distributed rebar arranged in the wall comprises an oblique section and a vertical section; and the oblique section of the vertically distributed rebar is obliquely intersected with a horizontal construction joint of the shear wall. According to the utility model, the loaded properties of the shear wall are improved, and the horizontal shear slip failure is prevented.
Description
Technical field
The shear wall that disposes local oblique reinforcing bar belongs to the concrete shear force wall technical field, relates in particular to a kind of shear wall that disposes local oblique reinforcing bar.
Background technology
Under geological process; Steel concrete is easy to cut the slippage changing of the relative positions along bending cracks or the constuction joint equipotential unboiled water straight snips of buying property; After the vertical muscle surrender in shear wall edge; Horizontal shear sliding deformation shared ratio in total deformation increases gradually, causes the energy dissipation capacity of shear wall to reduce, and is unfavorable to structural seismic performance.When shear wall construction, the constuction joint place tends to exist the weak floor of one deck scum silica frost or poor concrete grout (being that coarse aggregate is many, cement mortar is less) formation, shearing slip takes place when being prone to cause earthquake destroy.Seimic disaster census has been found the sliding rupture phenomenon of shear wall.
In order to control the sliding deformation at body of wall bottom or constuction joint place, improve the ductility and the energy dissipation capacity of shear wall, the shear wall of oblique reinforcing bar has appearred disposing.The regulation depth-width ratio is born by oblique reinforcing bar less than the shearing (at other potential slide surfaces is 25%, for example the constuction joint position) of 2 shear wall bottom 50% at least among the Eurocode 8 (european norm).But obvious, dispose oblique reinforcing bar and can bring certain difficulty to construction.
Summary of the invention
The purpose of the utility model is to improve the stress performance of shear wall, and the control shear wall interlayer horizontal shear slippage changing of the relative positions provides a kind of shear wall that disposes local oblique reinforcing bar.
The shear wall that the utility model disposes local oblique reinforcing bar is a concrete shear force wall, configuration level and vertical distribution reinforcement within the walls, and vertical distribution reinforcement is formed with oblique section by vertical section, the oblique section potential level shearing slip face oblique with shear wall; Potential level shearing slip face is meant in (under the geological process) under the horizontal reciprocating load, the position of body of wall occurred level shear strain, and for example with the horizontal construction joint of body of wall, perhaps each layer body of wall floor top side location, particularly body of wall root.In order to prevent sliding rupture, oblique section of the vertical distribution reinforcement horizontal construction joint oblique with body of wall; Perhaps vertical distribution bar is made up of vertical section of top with the bottom oblique section in each layer of shear wall, oblique section at the bottom of this layer wall with the floor level oblique.
The utility model compared with prior art has following advantage.
(1) can control the horizontal shear slippage of shear wall: oblique section of vertical distribution reinforcement with potential horizontal shear slide surface oblique, can effectively reduce the horizontal shear slippage, prevent shearing slip destruction.
(2) easy construction: the vertical distribution reinforcement of the utility model comprises vertical section with potential slide surface position oblique section, and construction is more convenient than the shear wall of the oblique reinforcing bar of existing configuration.
The shear wall that disposes local oblique reinforcing bar is applicable in shear wall structure or the frame shear wall structure.
Description of drawings
Fig. 1 is the shear wall sketch map of the local oblique reinforcing bar of configuration of the utility model; 1 is shear wall, and 2 is vertical distribution bar, and 3 is the potential slide surface of shear wall, and 4 is the horizontal distribution muscle, and 5 is floor.
Fig. 2 is the schematic cross-section among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
In Fig. 1; The utility model disposes the shear wall of local oblique reinforcing bar and is furnished with horizontal distribution reinforcing bar and vertical distribution reinforcement; In potential slide surface position (being floor epithelium constuction joint place among the figure); Vertical distribution bar bending certain angle (being generally 30 °-60 °), the bending part height is 100mm-0.5H (H is a This floor body of wall height).
The shear wall manufacturing process that the utility model disposes local oblique reinforcing bar is following.
(1) arranges level and vertical reinforcement according to the job practices of ordinary concrete shear wall; In potential slide surface position, vertical reinforcement is 30 °-60 ° of certain-length scope inner bendings.
(2) prop up template, concreting, maintenance then promptly gets the shear wall that disposes local oblique reinforcing bar after the form removal.
The shear wall and the common shear wall construction method that dispose local oblique reinforcing bar are basic identical, only need potential slide surface position that vertical distribution bar is bent.
Claims (3)
1. dispose the shear wall of local oblique reinforcing bar; This shear wall is a concrete shear force wall, and configuration level and vertical distribution reinforcement is characterized in that within the walls; Vertical distribution reinforcement is formed with oblique section by vertical section, oblique section of the said vertical distribution reinforcement potential level shearing slip face oblique with shear wall.
2. the shear wall of the local oblique reinforcing bar of configuration according to claim 1 is characterized in that, oblique section of the said vertical distribution reinforcement horizontal construction joint oblique with shear wall.
3. the shear wall of the local oblique reinforcing bar of configuration according to claim 1 is characterized in that, said vertical distribution reinforcement is made up of vertical section of top and oblique section of bottom in each layer of shear wall.
