Description
Technical field
The utility model belongs to building engineering field, more particularly to the connecting node of a kind of wallboard and beam.
Background technology
Assembling frame structure can greatly improve construction ability and construction speed, be ensured while saving a large amount of labours
Build guality.Connected mode is the key problem of the structure in assembling frame structural system, while is also the weakness of the structure
Link, as long as there is reliable connection the junction of prefabricated components, it just can guarantee that the safe and reliable of structure.In frame structure, mesh
Preceding conventional wallboard mounting means is that light-weight brick, building block and sheet material can be broadly divided into by filling the material of wall by the way of filling
Three classes, above-mentioned filled wall retaining design (retaining design refers to build and the enclosing thing in each face in room, such as door, window, wall,
The influence of adverse environment can effectively be resisted) in, wallboard is control wallboard anti-seismic performance with Vierendeel girder, the connecting node of post
Key factor, in the prior art, because filling wall still falls within masonry structure component, thus its globality is poor, fills wall and frame
Frame structure is unable to cooperative transformation, does not have relative displacement and corner between frame beam column and filling wall, and therefore, filling wall is past in earthquake
Toward can directly be destroyed, the Protection significance of wall in itself is lost.Secondly, using cast-in-place at prior art deadlight-girder connection, such as
Using composite beam, the pre-erection about 15-20mm of composite beam is shelved on the side of panel tops, side of the wallboard away from composite beam
Template (sandwich Side fascia can do exterior sheathing using outer impeller) is built, then cast-in-place concrete, panel tops are stretched out into steel
Together with muscle and composite beam termination Bar Anchorage.Although such a mode can guarantee that the globality of node and connection can to a certain extent
By property, but substantial amounts of cast-in-place work be present, node is mostly situ wet operation, and cloth muscle is complicated, not easy to operate, construction period
Slowly.
For assembling frame structure, especially low layer assembling frame structure (such as villa), in order to simplify connection as far as possible
Construction and construction technology, need badly develop a kind of cost savings, can effectively improve frame structure overall performance wallboard and beam
Connecting node.
