Description

A kind of composite heat insulation concrete shear wall
Technical field
The present invention relates to a kind of concrete building, particularly a kind of concrete shear force wall of composite thermal insulation.
Background technology
Existing high-story house mostly is concrete building, and framework-shear wall concrete building, framework-cylindrical shell concrete building, full shear wall concrete building and tube-tube wall concrete building are wherein arranged.
Available coagulation abode house room adopts the cast-in-place concrete structure system more, consume a large amount of timber and make template, can seriously consume the forest reserves, influences environment and weather.
The cast-in-situ concrete building structure is to construct at the scene entirely, and hand labour intensity is big, and the batch production level is low, and operation is many, and the cost height is long in time limit.
Existing energy-saving building technology is to grow up under the prerequisite that does not change existing house structural system.From formal branch two kinds of external wall outer insulation and exterior wall insulating temperature techniques are arranged, External Thermal Insulation Technology for External is to add the thermal insulation layer on the outdoor face of exterior wall, and the exterior wall insulating temperature technique is to add insulating on the inner surface of exterior wall.Divide from material, insulating has two kinds of board-like material and paste materials, no matter adopt sheet material still to adopt the slurry material, it is many that existing building external wall energy-saving technology all exists operation, the cost height, weak effect, safety inadequately, be shorter than 15 years service life, significantly shortcoming such as be not suitable on interior wall, using.
Nineteen forties to the seventies, the big board house of concrete room all appearred both at home and abroad, it is with the concrete panel of monoblock and the floor basic building block as the house, in the hope of reaching the purpose of plant produced and assemblingization.In order to save material, the big board house of concrete porous room has also been invented by China, facts have proved that the overall performance in this house is poor, can not satisfy the requirement of comfortableness.
Summary of the invention
The objective of the invention is, fully satisfy antidetonation, energy-conservation, save land, environmental protection, do not use loam brick, use wooden form less, under the prerequisite of fundamental state policies such as saving non-renewable resources, overcome the above-mentioned defective of prior art, the heat-insulated shear wall of the self-heat conserving house structural system that high performance concrete structure material of a kind of usefulness and high efficiency heat-insulation and heat-preservation material are provided is main material, it is convenient to batch production production and mechanized construction, safe and reliable, cheap, service life can be more than 50 years.
Technical scheme of the present invention is: a kind of concrete shear force wall of composite thermal insulation, comprise body of wall, coupling beam, it is characterized in that described body of wall comprises prefabricated thermal insulation concrete wall and in-situ concrete wall, the prefabricated thermal insulation concrete wall is covered with the concrete slab of adiabator layer for one side; At interval embedding in the prefabricated thermal insulation concrete wall have a steel member; Steel member one end places in the concrete slab, and the other end protrudes in outside the adiabator layer of prefabricated thermal insulation concrete slab; The steel member that connection is provided with along prefabricated thermal insulation concrete wall one side constitutes the cage of reinforcement of in-situ concrete wall; The superimposed one that is cast for of prefabricated thermal insulation coagulation body of wall and in-situ concrete wall.
Above-mentioned steel member can be T shape, L shaped steel disc, or T-shaped screw rod, can connect the screw rod of suitable length in the inner bolt hole screw rod.Leave the space around the steel member, during cast-in-place concrete wall, concrete is inserted in the space, strengthens the shear strength between the both concrete layers.
The position, boundary of above-mentioned coupling beam and body of wall, cast-in-place coupling beam is cast for one with cast-in-situ concrete layer up and down, and the outer face of coupling beam is covered with adiabator layer.
Above-mentioned coupling beam and position, body of wall boundary, coupling beam is provided with the double wedge perpendicular to upper surface, and the lower end of precast concrete plank is provided with corresponding grooves, prefabricated thermal insulation concrete wall and following coupling beam engagement; Two jiaos of intersections in lower end of coupling beam upper end and precast concrete plank, two jiaos of intersections in lower end of coupling beam upper end and precast concrete plank are embedded with steel plate and angle steel respectively on coupling beam and the precast concrete plank, during installation, both welding.The other end of precast concrete plank is embedded with the connecting reinforcement perpendicular to end face, and connecting reinforcement is fixedlyed connected with the cage of reinforcement of cast-in-place coupling beam, and connecting reinforcement constitutes the part of coupling beam cage of reinforcement.
It is prestressed concrete or steel concrete that above-mentioned prefabricated thermal insulation concrete wall adopts concrete slab.The material of above-mentioned adiabator layer can be polystyrol plastic foam plate or other organic expanded material; Above-mentioned in-situ concrete wall, floor are steel concrete.
The external surface that the present invention is used for the precast concrete body of wall of body of wall can have decorative pattern or bury the groove of pipeline underground, pastes or exempts on metope secondary and dig groove to replace additional facing, can reduce investment outlay, convenient construction.
Among the present invention, the prefabricated thermal insulation concrete wall is done template usefulness as the permanent formwork of wall outer side face during construction, becomes the ingredient of overlapped shear wall after construction finishes, and participates in stressed work.The construction measure that point connects when concreting, can play the effect of fixed form, does the time spent at bearing load, can guarantee composite bed permanent formwork and after the overlapping layers collaborative work of watering.The point ways of connecting can reduce cold (heat) bridge to greatest extent, thereby improves the heat-insulation and heat-preservation efficient of superimposed body of wall.
Beneficial effect of the present invention also is: the invention provides a kind of new energy saving building system, in exterior wall, party wall, use prefabrication thermal insulation concrete body of wall, and with this template as the cast-in-situ concrete part, need not dismantle these templates, form permanent thermal insulation concrete wall structural system.Improve the insulation of cast-in-situ concrete house structural system, heat-proof quality, met the building energy conservation developing direction, and reduced working procedure, shortened the duration, reduced cost, solved the problem of energy saving building complex process.
The present invention helps integrated design, modularization production, installation; Help improving build guality; Help accurately controlling the duration; Can realize site operation, dry operation, make concrete construction realize plant construction.
The present invention makes the easier energy conservation standard that reaches of building, improves sound insulation, heat insulation, heat-insulating property.Body of wall need not be done insulation layer in addition, and the percentage of usable dwelling area height is beneficial to secondary decoration.
