Abstract
The precast concrete sandwich wall that a kind of stalk is insulation material is the utility model is related to, belongs to building materials field.Straw heat-insulating board is between internal lobe concrete panel and siphonal lobe concrete panel, bar-mat reinforcement is located in internal lobe concrete panel on the inside of individual layer, double-deck outside bar-mat reinforcement is located in siphonal lobe concrete panel, and U-shaped or V-type basalt fiber tendons connector upper end passes through straw heat-insulating board, lower end and double-deck outside two-way concrete slab net clasp joint and inflection with bar-mat reinforcement clasp joint, middle part on the inside of individual layer.Advantage is structure novelty, the U-shaped or connected mode of V-type basalt fiber tendons connector and straw heat-insulating board, internal lobe concrete panel and siphonal lobe concrete panel used can both ensure the reliability of wall connecting, and can avoids wall from the problem of cold-heat bridge occur in junction, and then improve the anti-seismic performance of wall, globality etc., straw utilization efficiency can be effectively improved, promotes development of the industrialized building in China.
Description
Technical field
The utility model belongs to building materials field, refers in particular to a kind of heat insulation prefabricated concrete sandwich wall.
Background technology
Precast concrete is applied more and more extensive in building trade at present, and existing precast concrete sandwich wall has
Fragrant sandwich heat-preserving wall, EVG sandwich heat preservation 3D plates, CL sandwich heat preserving wall bodies, Te Momaisi sandwich heat preserving wall bodies etc. are breathed out,
Its insulation material is mostly using non-renewable materials such as polystyrene foam plastics, polyurethane foam plastics.Its connector is arranged
Mode mainly has three kinds：Straight cutting, vertical oblique cutting, straight cutting are aided with two-way oblique cutting.Its connecting piece material is mostly using stainless steel, glass
Fiber, cold-drawn zinc-coated wire, cold drawn wire etc..
But these existing precast concrete sandwich walls still suffer from many problems, such as insulation material used by it
（Including polystyrene foam plastics, polyurethane foam plastics etc.）Exist heat endurance it is poor, can the poor, poor fire of viscosity, construction
The problems such as property difference, while environmental pollution is easily caused, not environmentally.It is badly in need of finding a kind of reproducible insulation material to substitute at present
Material is stated, stalk is applied in precast concrete wall as a kind of renewable resource, will be greatly enhanced resource utilization.
Straw heat-insulating board is to crush stalk, mixes isocyanate glue, and after paving prefabricating, High frequency heating is into stalk board.Through to its thermal technology
The measure of performance and mechanical property, its result show stalk board（It is resin added 10% in preparation technology parameter, is made under pressure 25MPa
The thermal conductivity factor of the maize straw board obtained is 0.051 W/ (mK)）Heat-insulating property is preferable, while straw heat-insulating board intensity is high,
Adhesion strength is strong, and suction colloidality is good, and convenient material drawing, low cost, compared with conventional insulation material, has the uniquenesses such as energy-saving and environmental protection
Advantage, it is a kind of efficient green building insulation material.
Existing precast concrete sandwich wall is bearing larger wind load, level or vertical earthquake loading and deadweight
During load action, Side fascia is easy to fall off, and the globality of wall is very poor, and easily produces cold-heat bridge effect in junction, influences wall
The thermal property of body.
The content of the invention
The utility model provides the precast concrete sandwich wall that a kind of stalk is insulation material, existing pre- to solve
Concrete sandwich wall processed is when bearing larger wind load, level or vertical earthquake loading and gravity load acts on, Side fascia
Easy to fall off, the globality of wall is very poor, and easily produces cold-heat bridge effect in junction, and the thermal property for influenceing wall is asked
Topic.
The utility model adopts the technical scheme that：Straw heat-insulating board is located at internal lobe concrete panel and siphonal lobe concrete walls
Between plate, bar-mat reinforcement is located in internal lobe concrete panel on the inside of individual layer, and double-deck outside bar-mat reinforcement is located in siphonal lobe concrete panel,
Bar-mat reinforcement clasp joint on the inside of U-shaped or V-type basalt fiber tendons connector upper end and individual layer, middle part through straw heat-insulating board, lower end with
Double-deck outside two-way concrete slab net clasp joint and inflection.
The thickness of straw heat-insulating board described in the utility model is 70mm.
The thickness of internal lobe concrete panel described in the utility model is 60mm.
The thickness of siphonal lobe concrete panel described in the utility model is 100mm.
The utility model has the advantages that structure is novel, U-shaped or V-type basalt fiber tendons connector and the stalk insulation of use
The connected mode of plate, internal lobe concrete panel and siphonal lobe concrete panel can both ensure the reliability of wall connecting, and and can is kept away
Exempt from wall and occur the problem of cold-heat bridge in junction, and then improve the anti-seismic performance of wall, globality etc..Straw can be effectively improved
Stalk utilization ratio, approach is widened for the stalk recycling in China, the selection stalk suited measures to local conditions can solve as insulation material
The problem of certainly agricultural crop straw utilization ratio in rural area is low, energy-conserving and environment-protective, sustainable development is realized, can also realize residential standard
Change, large-scale production, promote development of the industrialized building in China.
