Description
Technical field
The present invention relates to a kind of connection method of fabricated shear wall, especially a kind of fabricated shear wall dry and wet mixing connects
Connect method.
Background technology
Shear wall structure is the important component of skyscraper, has higher bearing capacity and lateral deformation stiffness, can be effective
Horizontal shear is resisted on ground, has good anti-seismic performance.In recent years, China's building industrialization and Process of Housing Industrialization are accelerated,
Assembly of shear wall structure gradually attracts attention and extensive use, have situ wet operation it is few, it is easy for construction, to ambient enviroment shadow
The advantages that ringing small, transport resource and small human resources input has boundless in China's multilayer and high residential building
Application prospect.Fabricated shear wall is vertically connected since it bears horizontal shear and the big feature of horizontal bending moment load
Mechanical property is centainly challenged.
The vertical connection type of precast shear wall includes mainly steel bushing grouting connection and indirect overlap joint slurry anchor connection and machinery
Connect three kinds of modes.When using sleeve grouting connection type, since it is desired that slip casting in the enclosed space, therefore slip casting effect is not
It is good, and quality examination is difficult, and grouting quality is difficult to ensure, and steel bushing needs to use high strength steel, and process is complicated,
Cost is excessively high, and construction precision requires high, the unsuitable thinner reinforcing bar use in section.There is site welding works for reinforcement welding connection
The problems such as work amount is big, welding quality is difficult to ensure.There is site operation difficulty for indirect overlap joint slurry anchor connection greatly, preformed hole forming
The problems such as quality is difficult to ensure, thus in fabricated construction interior wall prefabricated rate it is relatively low, and after lifting cast-in-place structural up to
Temporary support is needed before to preset strength.
Therefore, it is necessary to develop a kind of new fabricated shear wall connection method, with reduce difficulty of construction, reduce cost,
Ensure reliable in quality and the mechanical property of shear wall after assembly can be effectively improved.

It is interior；When assembly, the upper layer prefabricated panel is lifted to lower layer's prefabricated panel first, and makes the connection reinforcing bar one by one
The bolt hole is accordingly passed through, the groove and the mouth that pours are buckled in the inverted U anchor rib and described vertical at this time
On anchor rib, the top of the inverted U anchor rib is located in the groove, and the upper end of the vertical anchor rib extends to described pour
It builds in mouth；It adjusts the upper layer prefabricated panel and is allowed to vertical, then use nut that will connect reinforcing steel bar locking in the bar connecting
On device, the contact for completing the upper layer prefabricated panel and lower layer's prefabricated panel left and right ends is located by connecting；Finally by
A mouthful cast-in-place concrete is poured, forms cast-in-place shear connector structure in the groove.
The intensity of cast-in-place concrete is not less than the intensity of prefabricated panel concrete in the groove.
The side wall inclination angle of the groove is the ゜ of 55 ゜~75, and depth is 200~300mm.
It is equipped with horizontal lacing wire on the top of the inverted U anchor rib, the horizontal lacing wire is located in the groove.
Two reinforcing bar connectors positioned at upper layer prefabricated panel the same end are socketed together by junction steel plate,
The junction steel plate is concordant with the bottom surface of upper layer prefabricated panel.
It is fixed with horizontally disposed roof supporting at the top of the angle steel section.
The vertical anchor rib includes two symmetrically arranged on the left and the right.
The invention has the advantages and positive effects that：
One) upper layer prefabricated panel and lower layer's prefabricated panel use four corners by nut by the connection reinforcing bar of anchoring with
The contact that reinforcing bar connector links together is located by connecting method, prefabricated panel needs in upper layer when can efficiently solve construction
The problem of support, eliminates the temporary support of wallboard, while saving support, keeps positioning more precisely and simple；It connects simultaneously
Touch location structure plays good fixed function, makes upper layer prefabricated panel when construction that can keep steady under wind action
It is fixed；After contact location structure completes construction, it can be undertaken by the connection reinforcing bar to lock on reinforcing bar connector certain
Pulling force undertakes a part of moment-in-plane, and the anti-bending strength of structure is made to be improved；Contact location structure avoids weldering simultaneously
Operation and Auxiliary support are connect, is fabricated construction truly, site operation is made to become more convenient.
Two) intermediate cast-in-place shear connector structure is formed using the closed groove in four sides is cast-in-place, can avoid using support shuttering,
It is easy for construction, cost can be reduced.Shear connector is formed after the completion of cast-in-place, can be improved the shear behavior of connection structure, be made dress
Overall performance with formula shear wall is improved.The convenient and efficient of site operation is realized while reducing cost；In groove
Inverted U anchor rib and the vertical anchor rib of band crotch that stretches into pouring hole form indirect overlap joint with vertical distribution bar in wallboard
The bending construction of connection, end can shorten the lap of splice, with traditional sleeve connection, be welded to connect and indirectly compared with slurry anchor connection
It constructs more simple and easy to do, cost is lower.
In conclusion the present invention sets up four reinforcing bar connectors separately by using at top wall panel both ends, and in top wall panel
Groove is set, by the structure of the casting concrete formation shear connector main body into groove, keeps upper layer prefabricated panel and lower layer prefabricated
The connection structure of wallboard is easy for construction, dependable performance effectively solves the advantages of connection with wet type present invention incorporates dry type connection
The problem of existing connection type site operation of having determined is difficult, quality is not easy to ensure can simplify work progress, improve assembly matter
Amount, the mechanical property for improving shear wall after assembly, to achieve the purpose that reduce cost.
