Description
Technical field
This utility model belongs to building structure technology field, particularly relates to a kind of wallboard and connects node.
Background technology
In assembled architecture industry, the design and installation of body of wall is prefabricated modular and installs, connecting elements is used to be attached between wallboard, for making to be connected as an entirety between wallboard and wallboard, so that it keeps continuously, and under the effect of the external force such as seismic force, horizontal shear and vertical counter-force etc. can be transmitted, not only the structural performance requirements of connecting elements is higher, simultaneously for connecting, the technological requirement installed is the strictest, therefore the connection of wallboard is one of construction procedure crucial in whole construction, being reliably connected between wallboard is also the emphasis in fabricated construction construction and difficult point.
At present, connection conventional method between wallboard is to use at wallboard medial surface reserved steel bar joint between wallboard and wallboard, casting concrete connected mode again after splice colligation, this kind of mode makes amount of reinforcement big, relatively costly and external force limited in one's ability of transmission horizontal direction.In prior art, patent CN203022131U discloses a kind of L-type wall inner corner trim integral level and connects node, including longitudinal prefabricated panel, horizontal prefabricated panel and L-type steel plate, the edge of described longitudinal prefabricated panel and horizontal prefabricated panel is all spaced and is embedded with silk braid, both vertical butt joint form L-type body of wall, longitudinal prefabricated panel and horizontal prefabricated panel in level to connecting into entirety, and by screw rod is connected with L-type steel plate spot welding；Although this connected mode is prevented from precast facade generation sidesway, but the connection of wallboard does not has globality, is unfavorable for the conduction of power between wallboard, is only connected by L-type steel plate simultaneously between wallboard, and under the effect of shear stress, this connects node destructible.
In sum, needing that a kind of attachment security of exploitation is reliable, good integrity badly, be unlikely to deform, the wallboard of low cost connects node.
Utility model content
The purpose of this utility model is to provide that a kind of attachment security is reliable, good integrity, is unlikely to deform, and the wallboard of low cost connects node.
Above-mentioned purpose is to be achieved through the following technical solutions: a kind of wallboard connects node, including the first wallboard, the second wallboard and in-situ layer, described first wallboard and the second wallboard constitute L-type structure, described first wallboard is provided with breach near the end of the second wallboard, described first wallboard is provided with dowel, described dowel extend out in described breach, is provided with interspersed reinforcing bar in described breach, and described interspersed reinforcing bar is positioned at the described dowel extension side away from the second wallboard；Being provided with soft-lock in described second wallboard, described soft-lock includes that ring portion and anchored end, described anchored end are embedded in the second wallboard, and described ring portion extend in described breach, and described ring portion through described ring portion and is anchored in described breach by described interspersed reinforcing bar；In described in-situ layer is filled in described breach and the first wallboard and the stitching portion of the second wallboard.Described first wallboard is loosed core formation breach by formwork erection in prefabrication process, it is possible to be in installation process, the first wallboard to be carried out cutting to offer breach.During the assembling of wallboard, first wallboard and the lifting of the second wallboard are L-shaped, the ring portion of soft-lock pre-buried in the second wallboard is extend in breach, then interspersed reinforcing bar is inserted described ring portion, when in-situ layer pours, the wallboard on breach three limit can be as the rib template of in-situ layer, it is only necessary at the formwork that carries out of vacancy, such easy construction.After in-situ layer pours, the part dowel of described first wallboard and the ring portion of second wallboard soft-lock by being anchored in in-situ layer, interspersed reinforcing bar and the first wallboard connects into entirety, and soft-lock, interspersed reinforcing bar, dowel and in-situ layer are reliably connected and are formed overall common stress.Should be appreciated that and be filled in by in-situ layer in set breach, can be effectively increased the contact area of the first wallboard and in-situ layer, in-situ layer is wrapped up therebetween by the first wallboard and the second wallboard simultaneously, so further enhances wallboard and connects the globality of node.Breach offered by first wallboard simultaneously, and the working place of such junction increases, it is simple to soft-lock and the installation of insertion reinforcing bar.
