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 technique
Shear wall structure is the important component of skyscraper, bearing capacity with higher 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 is widely applied, 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 investment 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 mainly includes steel bushing grouting connection and overlaps slurry anchor connection and machinery indirectly
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 is needed using 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 lower, and cast-in-place structural is reaching after lifting
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,
Guarantee reliable in quality and the mechanical property of shear wall after assembly can be effectively improved.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and provide a kind of fabricated shear wall dry and wet mixing company
Method is connect, using this method, easy construction, cost is relatively low, connection is reliable, can improve the mechanical property of shear wall after assembly.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of assembled shearing
Wall dry and wet mixed connection method is equipped with unfilled corner structure at four base angles of upper layer prefabricated panel, in the unfilled corner structure
It is fixed with the reinforcing bar connector identical with it, the reinforcing bar connector is equipped with vertically arranged angle steel section, in the angle steel section
Bottom is fixed with horizontally disposed connecting bottom board, and the connecting bottom board is concordant with the bottom surface of the upper layer prefabricated panel, described
Connecting bottom board is equipped with bolt hole, and the angle steel section is embedded in consistent manner on the upper layer prefabricated panel；In upper layer prefabricated panel
Bottom middle position be equipped with the closed groove in four sides, the top of the groove be equipped with pour mouth；In lower layer's prefabricated panel
Four vertex are equipped with the connection reinforcing bar opposite with the bolt hole correspondingly, and the connection Bar Anchorage is in the lower layer
On prefabricated panel, it is threaded at the top of the connection reinforcing bar；It is equipped with and institute in the top center position of lower layer's prefabricated panel
Groove opposite inverted U anchor rib and vertical anchor rib are stated, the inverted U anchor rib and the vertical anchor rib are anchored at institute
It states in lower layer's prefabricated panel；When assembly, the upper layer prefabricated panel is lifted to lower layer's prefabricated panel first, and make institute
It states connection reinforcing bar and passes through the bolt hole correspondingly, the groove and the mouth that pours are buckled in the inverted U anchor at this time
Gu on muscle and the vertical anchor rib, the top of the inverted U anchor rib is located in the groove, the vertical anchor rib it is upper
End extends to described pour in mouth；It adjusts the upper layer prefabricated panel to be allowed to vertically, reinforcing steel bar locking then will be connected using nut
On the reinforcing bar connector, the contact positioning of the upper layer prefabricated panel and lower layer's prefabricated panel left and right ends is completed
Connection；Finally by a mouthful cast-in-place concrete is poured, cast-in-place shear connector structure is formed 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 the upper layer prefabricated panel.
Horizontally disposed roof supporting is fixed at the top of the angle steel section.
The vertical anchor rib includes two symmetrically arranged on the left and the right.
The advantages and positive effects of the present invention are:
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, makes to position more accurate and simple；It connects simultaneously
Touch location structure plays good fixed function, is able to maintain upper layer prefabricated panel when construction under wind action surely
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, is improved the anti-bending strength of structure；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 be avoided using support shuttering,
It is easy for construction, cost can be reduced.Shear connector is formed after the completion of cast-in-place, be can be improved the shear behavior of connection structure, is made to fill
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 protrude into vertical distribution bar in the band vertical anchor rib of crotch and wallboard in pouring hole and form indirect overlap joint
The bending construction of connection, end can shorten the lap of splice, compared with traditional sleeve connection, welded connecting and indirect 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, reliable performance effectively solves the advantages of connection present invention incorporates dry type connection with wet type
Existing connection type site operation of having determined is difficult, quality is not easy the problem of guaranteeing, can simplify work progress, improves assembly matter
Amount, the mechanical property for improving shear wall after assembly, to achieve the purpose that reduce cost.
