A kind of keel type composite wall that has CCA panel clad can
Technical field
The utility model relates to a kind of keel type composite wall, especially relates to a kind of keel type composite wall of the CCA of having panel clad can.
Background technology
At present, the extensive use in low layer keel building of lightgage steel joist formula composite wall mostly is that gypsum plank is covered in the steel joist both sides and gypsum plank and corrugated steel board wall are covered in OSB board wall, steel joist both sides, also has the oblique drawstring of some steel joist bands both sides to cover gypsum plank and OSB board wall.There is the problem of aspects such as fire prevention, waterproof, durability in these bodies of wall, generally need plug-in side fascia, thereby have increased use cost.The CCA fiber cement board of ZHEJIANG HANGXIAO STEEL STRUCTURE CO.,LTD's exploitation has lightweight, high-strength, waterproof, fire prevention, anticorrosion, and advantages such as good endurance are the more superior building boards of a kind of combination property.This patent directly adopts the clad can sheet material of the CCA plate of high, medium and low different performance as inner, external wall.
The utility model content
The purpose of this utility model is exactly to provide a kind of anti-side performance that has in order to overcome the defective that above-mentioned prior art exists, and can fire prevention, waterproof, the durable keel type composite wall that has CCA panel clad can.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of keel type composite wall that has CCA panel clad can, this composite wall comprises:
Steel joist: be the cage construction of quadrature, as the brace rod of composite wall;
Cladding boards: be covered in the inside and outside both sides of steel joist, constitute the metope of composite wall;
The edge of described steel joist and the junction of quadrature connect through tapping screw.
Described cladding boards is the CCA panel.
The thickness of described CCA panel is 12mm.
Described steel joist is for forming the channel-section steel of orthohormbic structure.
Compared with prior art, the utility model has adopted the keel type composite wall of CCA fiber cement board clad can, can utilize CCA plate lightweight, high-strength, waterproof, fire prevention, anticorrosion, advantages such as good endurance, when general cladding boards being provided and having anti-side performance, also ensured fire prevention as the wall face requirement, waterproof, performance such as durable, be that a kind of structure is with the incorporate structure for building of finishing or go along with sb. to guard him innovative panellised wall.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of keel type composite wall that has CCA panel clad can, its structure as shown in Figure 1, this composite wall is made up of steel joist 1 and cladding boards 2.Wherein, steel joist 1 is the cage construction of quadrature, is made obtaining by channel-section steel, as the brace rod of composite wall.Cladding boards 2 is the CCA panel, is covered in the inside and outside both sides of steel joist 1, constitutes the metope of composite wall, and the thickness of CCA panel is 12mm.The edge of steel joist 1 and the junction of quadrature connect through tapping screw.
The CCA panel has lightweight, high-strength, advantages such as waterproof, fire prevention, anticorrosion, good endurance, it is the more superior building board of a kind of combination property, adopt CCA panel clad can, when ensureing exposed wall water proof, fire prevention, anticorrosion, durability, higher anti-side rigidity can be provided, and support for the keel column provides weak direction of principal axis, reduce slenderness ratio, improve stability bearing capacity.
