The vertical strip-shaped holes 62 can enable the mounting screws to move in the vertical strip-shaped holes, and the problem that the wall body is cracked due to stress generated by temperature difference is solved. In the embodiment, the lower end of the special-shaped supporting piece 3 is connected with the reinforced concrete floor slab through a special-shaped supporting fitting 6, and the composite partition wall is placed on the reinforced concrete floor slab which is overhung on each layer when the building structure is poured; the reinforced concrete floor slab of each floor selects a position with the same thickness as the wall body outside the steel beam, so that the wall body is placed on the floor slab of each floor, and the safety of the wall body such as earthquake resistance, wind load resistance and the like is ensured. As shown in fig. 5, an installation notch 35 passing through the light heat-insulating board 1 is formed on the partition plate 31 of the special-shaped supporting member 3 adjacent to one of the side steel rib plates, and when the last light heat-insulating board 1 is installed, because there are no more gaps, the installation notch 35 needs to be reserved, so that the light heat-insulating board 1 can be laid flat, and the opening length of the installation notch 35 in this embodiment is 600-800 mm.
The hardened leaf wall material is sprayed and coated on the reinforcing mesh 2 and the gap between the light heat-insulating board 1 and the reinforcing mesh 2 is filled to form the composite partition wall. In order to realize recycling waste and higher strength, the leaf wall hardening material is stone yard waste stone powder cement concrete, construction waste recycled concrete and solid waste recycled concrete/fine stone concrete/ceramsite concrete, and the compressive strength of the leaf wall hardening material is not lower than C10.
Example 2:
the structure of this embodiment is substantially the same as that of embodiment 1, except that, as shown in fig. 6, the connecting portion 32 of the special-shaped supporting member 3 is a hollow connecting square pipe having a plurality of sections, and each hollow connecting square pipe has a space therebetween. The strength of such a profiled support 3 is higher.
The invention also provides a manufacturing method of the bridge-cut-off support reinforcement cage sandwich composite partition wall, which comprises the following steps: (1) firstly, manufacturing the special-shaped supporting piece 3, the special-shaped supporting accessory 6 and the protective layer cushion block 4 by using flame-retardant plastics in a factory; (2) connecting the upper end and the lower end of a special-shaped support piece 3 with a connecting surface of a building structure through a special-shaped support fitting 6, binding and connecting the special-shaped support piece 3 and a protective layer cushion block 4 with a steel bar net 2 through a plastic wrapping binding wire, putting a light heat-insulating plate 1 into a bayonet of the special-shaped support piece 3, penetrating a connecting steel bar 5 through the light heat-insulating plate 1 and the protective layer cushion block 4, binding and connecting the protective layer cushion block 4 and the special-shaped support piece 3 on the other side with the other steel bar net 2 through the plastic wrapping binding wire, and connecting the connecting steel bar 5 with the steel bar nets 2 on the two sides in a spot welding manner to form a steel bar net cage; (3) and spraying a leaf wall hardening material on the reinforcing mesh 2, wherein the leaf wall hardening material is sprayed and coated on the reinforcing mesh 2, and gaps between the light heat-insulating board 1 and the reinforcing mesh 2 are filled to form the composite partition wall.
In the step 2, after the last light heat-insulating board 1 is placed into the bayonet of the special-shaped supporting part 3 through the installation notch 35, the installation notch 35 can be sealed through the strip plate, and the strip plate is connected with two ends of the installation notch 35 through screws.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
