Description
Technical field
The invention belongs to the technical field of building structure, specially a kind of assembling frame large-scale construction board and its manufacture
Technique.
Background technology
The house of the building construction of the prior art, especially single-layer or multi-layer is built, and whether uses post and panel structure, still
Using concrete structure, be required for making at the scene, used in material proportion it is larger, therefore it is required that its supporting structure (is held
Weight structure) it must also be designed larger, it can just meet the requirements, so, house overall weight also greatly increases, this is just needed
Good foundation structure makes construction cost and construction time extend, and construction cost rises.
In order to reduce construction cost, shorten the construction time, also someone uses light assembling house in recent years, i.e., first use timber or
Metal builds the structural framing in house, then uses hollow plastic plate as partition wall and roof, although this house solves cost of erection
With with construction time problem, but its is heat-insulated, sound insulation value is poor, and in order to improve heat-insulated, sound insulation value, someone uses double-layer plastic
Plate, the way of central filler heat-barrier material must make at the scene, time-consuming and laborious, and house integral strength is not also high, meet sudden and violent
Wind and rain especially typhoon when be easy ruined.
In the prior art, people build simple building or interior decoration, frequently with the way of lightgage steel joist：First press design
Scheme built lightgage steel joist, then sheet is installed in one side of keel or both sides, for internal wall finishing, these sheets are more
Using plasterboard.
The method that this in-site installation sets up wall has the characteristics that construction is flexible, and shortcoming is that working procedure is more,
Work efficiency is low.
Chinese patent CN200610035946.7 describes a kind of assembling frame large-scale construction board and its manufacture
Technique comprising two pieces of tablets and the core plate being clipped between two pieces of tablets, the core plate include to make to form envelope set on edge
The frame of the lightweight thermal insulation material filled in the cavity that the frame of side structure and these frames are surrounded, tablet and core plate it
Between use self-tapping screw reinforcement by connection.Its manufacturing process has filling type, flat-die rolling-type and molding type.The present invention is prefabricated with light
The building board of matter keel, when use, mutual frame was connected to become overall structure, has the function of keel, ensures house tool
There is good structural behaviour：Wind resistance, antidetonation, antitheft (in bar-mat reinforcement built in tablet), moisture-proof etc..Set of the present invention lightweight, height
By force, the excellent performances such as heat-insulation and heat-preservation, fire prevention, moisture-proof, also have the characteristics that build house quick, at low cost, and building board can be with
It is recycled for multiple times, energy conservation and environmental protection, great application value.But the program, in producing assembling process, process is more, it is multiple
It is miscellaneous, undoubtedly also increase cost, when being built especially for building site prefabricated house, a kind of structure more stablizes, sound insulation with it is moisture-proof
The better plank of effect is the demand in present market.
