At present, external walls need to be constructed on a steel structure frame or a concrete frame during building construction, and cast-in-place external walls, masonry type external walls, prefabricated external walls and the like of a field-assembled framework exist. The cast-in-place wall body with the framework assembled on site is characterized in that a top keel is horizontally installed on the inner side of a cross beam of a frame structure, two ground keels are installed on the ground, the distance between the top keel and the lower end of the top keel is consistent with the thickness of the cross beam, the upper end of a vertical outer side light steel keel is connected with the outer side of the cross beam, the lower end of the vertical outer side light steel keel is connected with the outer side ground keel, a vertical inner side light steel keel corresponding to the vertical outer side light steel keel is installed between the top keel and the inner side ground keel, a plurality of rows of broken bridge connecting pieces are connected between the vertical outer side light steel keel and the vertical inner side light steel keel, an outer wall plate is. When the wall body of the corner is manufactured, keels are required to be arranged on the periphery of the structural columns on site, then the non-dismantling formworks are connected, and the wall body is formed after light concrete is poured. For this purpose, the structural columns are provided with reinforcing bars or welded reinforcing bars to achieve the connection with the keel. Not only the operation is troublesome, but also potential safety hazards exist in field welding.

Disclosure of Invention

The utility model relates to a solve the above-mentioned technical problem that prior art exists, provide a prefabricated corner wall body of construction easy operation, security height.

The technical solution of the utility model is that: the utility model provides a prefabricated corner wall body, is equipped with first wallboard and the second wallboard that meets perpendicularly, first wallboard meets with the second wallboard and holds inboard all to meet with first vertical side pipe side, first wallboard inboard meets with second vertical side pipe side, second wallboard inboard meets with third vertical side pipe side, second vertical side pipe and third vertical side pipe are 45 ~ 70mm apart from first wallboard end and second wallboard end horizontal distance respectively, and the interval is provided with many horizontal side pipes between first vertical side pipe and second vertical side pipe and between first vertical side pipe and third vertical side pipe, and the inboard horizontal side pipe department of first wallboard and second wallboard is fixed with the horizontal steel band of width such as with first wallboard and second wallboard, first wallboard and the inboard first heat preservation that covers of second wallboard have thickness to be 35~40 mm.

The utility model discloses only need with the fastener pass the wallboard of prefabricated corner wall body and the extension section of horizontal steel band meet with the skeleton in the wall body and add the heat preservation and seal up fire-retardant sealed glue with the seam crossing can. The external corner can be ensured to be vertical, the high-altitude operation time of workers can be reduced, potential safety hazards in field welding can be eliminated, and the method has the advantages of being simple in construction operation, high in safety and the like.
