Description

A kind of assembly concrete building prefabrication exterior wall L shape vertical joint node structure
Technical field
The utility model relates to assembling type outer wall waterproof field more particularly to a kind of assembly concrete building prefabrication exterior walls L shape vertical joint node structure.
Background technique
With tradition it is cast-in-place building compared with, assembled architecture realize standardized designs, the factorial production, prefabricated construction, Integrated finishing and information system management, substantially reduce the negative effect to environment, and realizing reduces noise fugitive dust, reduces construction dirt Dye saves water, electric resources, it has also become the inevitable choice of construction industry technology upgrading.However, assembled architecture on-site consolidation can leave A large amount of assembly seams, these seams easily become the channel of water flow infiltration, and external wall waterproof has congenital weakness.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of assembly concrete building is provided Precast facade L shape vertical joint node structure, the node structure are formed with using polyethylene item, vertical normal pressure draining cavity L-type seam construction extends infiltration path, blocks the access of water, ensure that waterproofness, effective solution outer wall joint waterproof Problem, and it is reasonable in design, it is easy for construction.
Outside a kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: assembly concrete building prefabrication Wall L shape vertical joint node structure, include beams of concrete, siphonal lobe concrete slab, prefabricated sandwich heat preservation outer wall template, it is two-sided from Viscous butyl rubber belt, polyethylene item, vertical normal pressure drain cavity, back lining materials, sealant layer;The beams of concrete is cast-in-place Reinforced concrete structure, beams of concrete outside are provided with prefabricated sandwich heat preservation outer wall template;The prefabricated sandwich heat preservation exterior wall Double-sided self-adhesive butyl rubber belt, and double-sided self-adhesive butyl rubber belt pair are provided on horizontal, vertical direction between template and beams of concrete It answers on prefabricated sandwich heat preservation outer wall template position there are rectangular recess, and is filled with polyethylene item in rectangular recess;It is described It is provided with siphonal lobe concrete slab on the outside of prefabricated sandwich heat preservation outer wall template, which corresponds to polyethylene position Place is provided with vertical normal pressure draining cavity;The vertical normal pressure draining cavity is with the snap of polyethylene one end and perpendicular to poly- Vinyl foam item, the vertical normal pressure draining outer side of cavity are provided with back lining materials;It is provided on the outside of the back lining materials close Adhesive layer.
Preferably, the sealant layer is formed by weatherability buildings waterproof sealant processing.
Preferably, the double-sided self-adhesive butyl rubber belt is wider than polyethylene item.
The beneficial effects of the utility model are: the node structure drains cavity shape using polyethylene item, vertical normal pressure At there is L-type seam construction, infiltration path is extended, the access of water is blocked, ensure that waterproofness, effective solution outer wall joint Waterproof problem, and it is reasonable in design, it is easy for construction.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application Point, but do not constitute the restriction to the utility model.
A kind of assembly concrete building prefabrication exterior wall L shape vertical joint node structure schematic diagram of Fig. 1.
Wherein: 1 is beams of concrete, and 2 be siphonal lobe concrete slab, and 3 be prefabricated sandwich heat preservation outer wall template, and 4 be double-sided self-adhesive Butyl rubber belt, 5 be polyethylene item, and 6 drain cavity for vertical normal pressure, and 7 be back lining materials, and 8 be sealant layer.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of assembly concrete building prefabrication exterior wall L shape vertical joint node structure, includes concrete It is beam 1, siphonal lobe concrete slab 2, prefabricated sandwich heat preservation outer wall template 3, double-sided self-adhesive butyl rubber belt 4, polyethylene item 5, vertical Normal pressure drains cavity 6, back lining materials 7, sealant layer 8;The beams of concrete 1 is monolithic reinforced concrete structure, the concrete Prefabricated sandwich heat preservation outer wall template 2 is provided on the outside of beam 1;Water between the prefabricated sandwich heat preservation outer wall template 3 and beams of concrete 1 Double-sided self-adhesive butyl rubber belt 4 is provided on flat, vertical direction, and outside the corresponding prefabricated sandwich heat preservation of double-sided self-adhesive butyl rubber belt 4 There are rectangular recess on 3 position of wall form, and polyethylene item 5 is filled in rectangular recess;Outside the prefabricated sandwich heat preservation It is provided with siphonal lobe concrete slab 2 on the outside of wall form 3, is provided at corresponding 5 position of polyethylene item of the siphonal lobe concrete slab 2 perpendicular Cavity 6 is drained to normal pressure;The vertical normal pressure draining cavity 6 and the 5 one end snap of polyethylene item are simultaneously steeped perpendicular to polyethylene Foam item 5, the vertical normal pressure draining outer side of cavity 6 are provided with back lining materials 7;Sealing is provided on the outside of the back lining materials 7 Glue-line 8.
When it is implemented, the sealant layer 8 is formed by weatherability buildings waterproof sealant processing.
When it is implemented, the double-sided self-adhesive butyl rubber belt 4 is wider than polyethylene item 5.
