Description
Technical field
The invention belongs to construction engineering technical fields, especially relate to a kind of assembled based on multipurpose thin-wall steel tube
Concrete shear force wall and its method of construction.
Background technology
Currently, the connection method of the vertical distribution bar of assembly concrete shear wall, is mainly the following mode：
《Reinforced bar sleeve grouting connection application technology regulation》Connection method in JGJ 355-2015 is that current assembled is mixed
The main connection method of Xtah Crude Clay structure reinforcing bar, but this technology is due to examining difficulty, being affected by human factors larger and receiving matter
It doubts, industry thinks unstable quality, unreliable；And the vertical distribution bar amount of concrete shear force wall is more and diameter is thin, the company of causing
Be connected into it is excessively high, in order to promote the popularization of assembled architecture,《Prefabricated concrete structure technical regulation》JGJ1-2014 will《It is high
Layer building concrete structure technology regulation》Homonymy bar spacing as defined in JGJ3-2010 has been increased to 600, one by 200~300
Determine to reduce reliability of structure in degree.
《Extrusion Connected Method of Reinforcing Steel Bar regulation》JGJ 108-96, this rebar connecting technology, for assembled
The bar connecting of concrete structure, has been only applicable under conditions of operating space, can be applicable in horizontal reinforcement connection, for perpendicular
To bar connecting and impracticable, and the difficult point of prefabricated concrete structure bar connecting is that the connection of vertical reinforcement.
Heilungkiang Yu Hui groups assembly integrated precast concrete shear wall structural system, using reinforced binding slurry anchor overlap joint
The form of connection carries out the connection of shear wall vertical reinforcement, for its essence, is had no significantly with reinforced bar sleeve grouting connection
Difference, q＆r are also essentially identical.
Publication number CN103485548B, assembled hollow concrete overlapped shear wall Vertical bar connection method, by with
Lower step is realized.Step 1: the vertical distribution bar in shear wall wallboard is thrown away upwards, it is reserved to get rid of reinforcing bar outside, under component
Slot is arranged in portion, reinforcing bar contraposition overlap joint connection when facilitating the installation docking of levels component；Step 2: getting rid of reinforcing bar peace outside member upper
Floor position is passed through when dress；Step 3: the hollow concrete of last layer is sheared into the vertical hole of wall member counterpart member, it will be next
The outer reinforcing bar that gets rid of of story shear wall member is inserted into hole, will be got rid of outside in reserved mounting groove hole location vertical in reinforcing bar and component
Reinforcing bar realizes overlap joint connection；Step 4: pouring concrete at hollow parts for core filling, completes the installation of component, component is made to form one
A entirety.The invention makes that the connection of assembled hollow concrete shear wall vertical reinforcement becomes simple, quality is easy to ensure, improve
Productivity, it is ensured that building construction quality and reducing the construction costs.But there is precast concrete shearings for this technical solution
Wall top portion it is outer get rid of reinforcing bar it is longer, occupy production space it is larger, get rid of outside reinforcing bar increase production prefabricated panel difficulty, reduce
Production efficiency, the outer profile size of prefabricated panel are larger, transport is inconvenient, and precast hollow hole core pulling is difficult, increases process, production
The shortcomings such as efficiency is low.
The application for a patent for invention file of application number 201710373977.1 discloses a kind of prefabricated assembled double steel pipe coagulation

Soil is cast in the concrete steel pipe outside steel pipe Wai, the square stirrup being arranged outside steel pipe, is arranged and vertically divides in steel pipe front and rear sides
It steel tie between steel pipe and vertical distribution bar and horizontal distribution reinforcing bar of cloth reinforcing bar and horizontal distribution reinforcing bar, drawknot and sets
Set the longitudinal reinforcement in both sides of the edge confining part position；Embedded steel pipe, utilizes steel pipe in ordinary reinforced concrete shear wall
Effect of contraction improve concrete bearing capacity, and then in the case that design axle power it is identical reduce component sectional dimension, subtract
Small dead load reduces geological process, more usable floor areas is provided for building；Using concrete filled steel tube high-bearing capacity and
High ductility effectively improves the anti-bending bearing capacity of shear wall, shear-carrying capacity, destroys the anti-seismic performances such as ductility.But this technology
The problem is that：Steel pipe is only used for improving the performance of shear wall, has no other purposes, and be only applicable to cast-in-place concrete knot
Structure.
The connection method of the existing vertical distribution bar of assembly concrete shear wall, the scheme using grouting connection exist
Quality not know and the high problem of cost；Using precast hollow hole concrete panel, rear pouring concrete is realized in hollow hole
It directly overlaps, the indirect scheme overlapped or be mechanically connected, there is pore-forming process difficulty, and big, reduction efficiency and raising cost etc. are asked
Topic；In order to solve the problems, such as that these exist, it is badly in need of proposing new technical solution.
