Abstract
The invention discloses a tooth-groove-type connection structure of an upper-layer inner wallboard of an assembly-type shear wall and a lower-layer inner wallboard of the assembly-type shear wall. Each inner wallboard comprises two contact locating structures of the upper-layer inner wallboard which are respectively arranged at two ends of each wallboard and a post-pouring concrete structure. The post-pouring concrete structure is located between the two contact locating structures. Upper grooves are formed in the bottom surface of the upper-layer inner wallboard, upper tooth-shaped grooves are formed in the bottoms of the upper grooves, and vertically-distributed rebars of the upper-layer inner wallboard stretch out from the upper grooves. Lower grooves are formed in the top surface of the lower-layer inner wallboard, lower tooth-shaped grooves are formed in the bottoms of the lower grooves, and vertically-distributed rebars of the lower-layer inner wallboard stretch out from the lower grooves. When the upper-layer inner wallboard is connected with the lower-layer inner wallboard, notches of the upper grooves are connected with notches of the lower grooves in a butt joint mode, forming grooves of the post-pouring concrete structure are formed, and the vertically-distributed rebars of the lower-layer inner wallboard and the vertically-distributed rebars of the upper-layer inner wallboard are correspondingly connected in a lap joint mode. The tooth-groove-type connection structure of the upper-layer inner wallboard of the assembly-type shear wall and the lower-layer inner wallboard of the assembly-type shear wall is easy and convenient to construct and reliable in structure.
Description
Technical field
The present invention relates to building structure field, particularly a kind of fabricated shear wall levels lining Alveolus type syndeton.
Background technology
At present, the shear wall structure of traditional cast-in-place form also exists the problems such as work on the spot amount is large, construction material waste is many, build water waste, environmental pollution is serious.Built fabricated shear wall structure lining vertical connection structure many employings sleeve grouting connects, reinforcement welding connects and is connected with indirect overlap joint slurry anchor.Sleeve grouting connect also exist sleeve high cost, construction precision requirement high, be not suitable for the problems such as the thinner reinforcing bar employing in cross section; Reinforcement welding connects and also exists that Site Welding workload is large, welding quality is difficult to the problems such as guarantee; Indirect overlap joint slurry anchor connects and also exists that site operation difficulty is large, preformed hole forming quality is difficult to the problems such as guarantee, and therefore in fabricated construction, the prefabricated rate of interior wall is lower, and cast-in-place structural needs temporary support before reaching intensity after lifting.
Sleeve grouting connects and indirectly overlap joint slurry anchor is connected and belongs to dry connection, if dealt with improperly, hold at horizontal joint place and should easily occur stressed concentrated, formation plane of weakness, affects the overall performance of structure.And existing connected mode is not mostly distinguished according to story height, earthquake intensity etc., easily causes the phenomenons such as the stressed potential of connecting material can not give full play to, waste of material is serious.
Summary of the invention
The present invention provides a kind of easy construction, structure reliable fabricated shear wall levels lining Alveolus type syndeton for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of fabricated shear wall levels lining Alveolus type syndeton, every sheet lining comprises point two the upper strata lining contact location structures being located at its two ends and a rear pouring concrete structure, and described rear pouring concrete structure is between two described contact location structures; The bottom surface of upper strata lining is formed with upper groove, is formed with top tooth-like recesses in the bottom of described upper groove, the vertical distribution bar of described upper strata lining stretches out upper groove; The end face of lower floor's lining is formed with low groove, is formed with bottom tooth-like recesses in the bottom of described low groove, the vertical distribution bar of described lower floor lining stretches out low groove; When described upper strata lining is connected with described lower floor lining, described upper groove and the docking of described low groove notch, form the grooving of described rear pouring concrete structure, the vertical distribution bar of described lower floor lining and the vertical distribution bar correspondence overlap joint of described upper strata lining.
Described contact location structure comprises the upper joint steel pipe be embedded in the lining of described upper strata and the lower joint steel pipe be embedded in described lower floor lining, described upper joint steel pipe be provided with stretch out lining bottom surface, described upper strata stretch out pipeline section, when described upper strata lining is connected with described lower floor lining, the described pipeline section that stretches out is inserted in described lower joint steel pipe, is bolted between them.
Described lower joint steel pipe and described upper joint steel pipe are all connected with anchor bar.
Be equipped with stiffener around described lower joint steel pipe and described upper joint steel pipe, the root of stiffener described in every root is all formed with the right angle crotch with horizontal distribution reinforcing bar binding, and all described stiffeners form groined type structure at their top.
Bottom on described in joint steel pipe and described lower joint steel pipe is equipped with steel plate and cuts off.
The advantage that the present invention has and good effect are:
One) the contact location structure of upper strata lining adopts the structure of two steel pipe grafting, efficiently solving the problem that shear wall upper strata lining supports, eliminating the temporary support of wallboard when constructing, and while saving supports, makes location more accurate and simple; Simultaneously location structure serves good fixation, and when making construction, shear wall upper strata lining can keep stable under wind action; Connected by two joint steel pipe bolts, after structure completes, steel pipe can bear certain pulling force, bears moment-in-plane together with cast-in-place edge member, and the anti-bending strength of structure is improved.The contact location structure of upper strata of the present invention lining avoids any type of welding and supplemental support, is fabricated construction truly, makes site operation become more convenient.
Two) the rear pouring concrete structure of prefabricated lining adopts teeth groove shape, forms shear connector, can improve the shear behavior of syndeton, the overall performance of fabricated shear wall is improved after overall structure completes.The present invention achieves the convenient and swift of site operation while reduction cost; The vertical distribution bar of upper wainscot sheathing only needs to carry out overlap joint connection and can meet the demands in teeth groove, with sleeve connection, is welded to connect and indirectly starches anchor and connect and compare construction and get up more simple and easy to do.
In sum, the present invention sets up the contact location structure of upper strata lining separately at every sheet lining two ends by adopting, and between two contact location structures, form the grooving of rear pouring concrete structure, make this syndeton easy construction, dependable performance, efficiently solve the problem that existing connected mode site operation is difficult, cost is high.
