A kind of double-layer plate heat-preservation shear wall
Technical field
The utility model belongs to building field, relates to the heat preservation technology of high-rise and superelevation story shear wall.
Background technology
Because present widely used External Thermal Insulation Technology for External has application life short (needing to change insulation layer in the military service phase of structure), construction trouble and is easy to shortcoming such as cracking, so the sandwich thermal insulated technology of exterior wall has and same life-span of structure, advantage such as not easy to crack, accelerates development at present.But the sandwich thermal insulated technology that how to solve high-rise and superelevation story shear wall is a difficult point, what use was more at present is embedded insulation layer in the middle of reinforced concrete shear wall, this technology is used for the lower structure of the number of plies and still can, be used for high level or superelevation layer structure, then the anti-seismic performance of structure may not meet the demands.
Steel plate shear force wall is a kind of new structural system, the framework that it utilizes edge posts and edge girder to form is born the structure vertical load, be mounted in steel plate between edge posts and the edge girder and bear the horizontal earthquake action of structure, structure stress is reasonable, has following advantage: alleviated the wall thickness of structure, promptly increased the usable floor area of structure; Alleviate dead load, reduced foundation load and geological process simultaneously; The ductility of structure is good, can stand very big distortion; Anti-seismic performance is good, and the test and the performance that have withstood actual earthquake are good; Speed of application is fast.
Summary of the invention
The purpose of this utility model is to solve preferably the insulation problem of high-rise and superelevation layer structural shear wall, the utility model is by build-in double-layer plate between edge posts and edge girder, fill insulant material between double-layer plate, satisfying high-rise and superelevation layer structural seismic set up defences and realized wall thermal insulating in the requirement, realizing anti-seismic performance and the incorporate design of heat-insulating property that shear wall is good.Special needs to be pointed out is, the utility model is two distinct notions with widely used sandwich color steel plate at present, the sandwich color steel plate is mainly used in building maintenance structure, the shearing that self can bear is very little, belong to non-structural element, the thickness of color steel is generally between 0.4mm~1.5mm, double-layer plate shear wall of the present utility model is a structural element, steel plate is used for bearing the horizontal earthquake action of structure, so steel plate thickness is very big, generally between 5mm~60mm, and the steel plate outside need be provided with steel plate level and vertical stiffening rib.
For reaching above purpose, solution of the present utility model is:
A kind of double-layer plate heat-preservation shear wall, it comprises double-layer plate, heat insulating material, edge posts, edge girder, steel plate level and vertical stiffening rib, horizontal stiffening rib and vertical stiffening rib, double-layer plate is mounted between edge posts and the edge girder, fill insulant material between double-layer plate.
Described double-layer plate, the thickness of its every layer steel plate are 5mm~60mm.
The outside of described double-layer plate need be provided with steel plate level and vertical stiffening rib.
Described edge posts is steel column, steel core concrete column and reinforced concrete post; Described edge girder is girder steel, steel tube concrete beam and reinforced concrete beam.
Described edge posts is the I shape steel column, and then this edge posts must be established horizontal stiffening rib; Described edge girder is an i-shape steel beam, and then this edge girder must be established vertical stiffening rib.
The outside of double-layer plate can be provided with fireproof paint by the fire protection requirement of steel work.
The heat insulating material of filling between the double-layer plate can be rock wool, glass wool, polystyrene foam plastics, foam glass.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
1. double-layer plate is resisted horizontal earthquake action, and the framework that edge posts and edge girder are formed is born vertical load, and structure stress is clear and definite, anti-seismic performance is good, and increases the structure usable floor area, alleviates dead load, easy construction, the technician understands easily when using and grasps, and is convenient to operation.
2. fill insulant material between the double-layer plate has insulation layer and the structure advantage with the life-span.
3. factory prefabricating degree height, easy construction, power transmission are reliable, have realized the load-bearing and the heat insulation integrated design of high-rise and superelevation story shear wall.
