Description

Assembled built-in heat insulation layer concrete composite wall-light steel frame connecting node
Technical field:
The utility model belongs to wall connecting node manufacture technology field in structural engineering, and in particular to a kind of assembly Formula built-in heat insulation layer concrete composite wall-light steel frame connecting node and the practice.
Background technique:
Current China is in the quick process of urbanization, realizes " comprehensive well-off " to the year two thousand twenty, the level of urbanization reaches To 60% or so, urban population about increases by 300,000,000, and urbanization dwelling construction quantity will keep higher level in a long time.So And current newly-increased building is still built with the rough type construction method of traditional high energy consumption, high pollution.Propulsion building industrialization, Residential housing industrialization is to realize dwelling construction mode from extensive style to intensive style transformation, raising housing quality and save house The important measure of energy consumption is the important channel for guaranteeing Sustainable Construction Industry, has extremely to China's economy and social development Profound significance.
Light steel frame refers to be cut by the hot rolled H-shaped of small bore, high frequency welding of H-structural steel, common welded H section steel or abnormity The pure Beam-post Frame Structure or beam column frame-Bracing Systems of the components such as the steel pipe of face fashioned iron, cold rolling or hot-roll forming composition, Have the characteristics that structure construction is simple, dismounts convenient, flexible layout.Develop assembled light steel frame, it can be achieved that component is pre- System, in-site installation, can effectively save resource, reduce energy consumption, while greatly the construction time is shortened, to realization building industrialization Have with housing industrialization and Urbanization Construction and is greatly promoted effect.
Beam column is as main structure, more mature in fabricated construction technology but matched assembled wallboard Structural system research but relatively lags behind.One of the important indicator of examination fabricated construction industrialized level is exactly the assembling of wallboard The difference of the assembly connection form of degree, wallboard and main body frame, to the rigidity of main structure, there are large effects, unreasonable The destruction for resulting even in main structure is set.Existing assembled wallboard is mostly assembled out-hung panel, mostly as the outer of structure Fender member does not provide rigidity and bearing capacity to main structure, on the contrary, out-hung panel has certain mass, increase structure by The gravity laod of power component, to increase the design strength and project cost of main structure.
The connectivity problem for how more reliably realizing beam column on assembled wall and light steel frame, so that wallboard be made to become The problem of bearing carrier, is never well solved, and is development and popularization and application fabricated construction residential housing body Urgent problem to be solved in system, and the major reason for causing fabricated construction building systems to be unable to large-scale popularization.
Summary of the invention
This patent provides a kind of simple structure, assembled built-in heat insulation layer coagulation easy for construction, connection is safe and reliable Native composite wall-light steel frame connecting node and the practice, to solve the company in light steel frame between assembled wall and frame Problem, while effectively maintenance light steel frame beam column component are connect, corrosion of steel is reduced, reinforces fire prevention, be suitble in low multilayer assembled Wide popularization and application in light steel frame.
To achieve the above object, the utility model adopts the following technical solution:
Assembled built-in heat insulation layer concrete composite wall-light steel frame connecting node, including it is outer page concrete (1), built-in Insulating layer (2), interior page concrete (3), concrete frame (4), the orthogonal steel mesh of outer page (5), frame steel mesh (6), interior page are just It hands over steel mesh (7), pre-embedded bolt (8), be bolted groove (9), angle cleat (10), light steel frame column (11) and light steel frame Beam (12);The orthogonal steel mesh of outer page (5) being arranged in the middle part of outer page concrete (1), in concrete frame (4) location arrangements frame Steel mesh (6) and pre-embedded bolt (8) pour outer page concrete (1), and built-in heat insulation layer (2) is placed on outer page concrete (1) Layer, in built-in insulating layer (2) surrounding casting concrete frame (4), the orthogonal reinforcing bar of interior page being arranged in the middle part of interior page concrete (3) Net (7) pours interior page concrete (3), reserves at composite wall pre-embedded bolt (8) position when pouring and is bolted groove (9), wall Plate conserves to form assembled built-in heat insulation layer concrete composite wall;It is welded on (12) in light steel frame column (11), light steel frame beam Angle cleat (10) with prepared screw-bolt hole, when assembly, the pre-embedded bolt (8) on composite wall is passed through on angle cleat (10) Bolt hole is connect with light steel frame, forms assembled built-in heat insulation layer concrete composite wall-light steel frame connecting node.
