Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing.
[0023] Such as Figure 1-6 As shown, the prestressed steel plate with masonry composite wall of the present invention comprises a masonry wall 1, and the front and rear facades of the masonry wall 1 are provided with a rectangular steel frame 6 along the periphery, and the rectangular steel frame is composed of angle steel, adjacent Angle steels are connected by welds formed by welding. The leg length of the angle steel is 80mm and the thickness is 10mm. The angle steel with a leg length of 50-200mm and a thickness of 3-18mm can be selected according to actual needs. In the middle of the rectangular steel frame, there is an orthogonal steel strip with prestress applied. The orthogonal steel strip is fixed on the rectangular steel frame 6 through the weld 5 formed by welding. The width of the steel strip is 100mm and the thickness is 5mm, which can be selected according to a...

The invention discloses a prestressing steel plate strip masonry combined wall comprising a masonry wall body. Rectangular steel frames are arranged on the front and back facades of the masonry wall body correspondingly along the periphery. Orthogonal steel plate strips for applying prestress are arranged in the middles of the rectangular steel frames. The opposite steel plate strips on the front and back faces of the masonry wall body are connected through split bolts penetrating through the masonry wall body. The utilization efficiency of steel plates is improved through prestress applying; the buckling strength of the steel plates can be effectively improved through lateral restraint; the prestressing orthogonal steel plate strips form certain constraint to the masonry wall body, so that the ductility capacity of the wall body is improved, the transverse bearing capacity and the vertical bearing capacity of the combined wall are improved, and anti-seismic performance is improved; and mechanized batch production can be achieved, the production efficiency is high, construction is convenient, and labor is saved.
Description
technical field [0001] The invention relates to civil engineering, in particular to a prestressed steel plate strip masonry composite wall. Background technique [0002] Masonry is one of the building materials, and the wall formed by it accounts for more than 50% of the existing buildings, whether it is used as a vertical load-bearing member or as a partition or enclosure part of a frame structure. Masonry walls generally need to be reinforced due to the following reasons: deterioration of material properties, that is, reduction of resistance; increase of vertical load, such as addition of floors or changes in use functions; improvement of seismic fortification category or seismic fortification intensity, such as kindergartens and primary schools in educational buildings The anti-seismic fortification category of the teaching rooms of middle schools, student dormitories and canteens has been raised from the standard fortification category to the key fortification category. ...
