Description

Technical Field

[0001] The utility model relates to the technical field of building walls, and particularly relates to a prefabricated and assembled fireproof and heat-insulating wall. Technical Background

[0002] An assembled wall is a wall formed by assembling bricks. During construction, first, bricks are assembled, and then the joints are fixedly connected with cement mortar. The assembly of such a wall and the subsequent installation method are complex. The on-site masonry of the wall greatly increases the construction time and labor cost; moreover, the strength of the wall is poor and it is easily damaged by external forces.

[0003] To solve the above problems, the Chinese utility model patent with the application number 202321358947.0 discloses a prefabricated and assembled wall, which is characterized in that: the wall includes multiple groups of bricks stacked up and down, a bottom connecting piece, multiple reinforcing bars and multiple angle steels. The vertical surface of the angle steel is attached to the side surface of the brick, and the horizontal surface of the angle steel is located in the gap between the brick and the adjacent brick; a group of bricks at the bottom is connected to the bottom connecting piece, and multiple reinforcing bars are vertically connected to the bottom connecting piece and penetrate through the bricks and angle steels stacked up and down. In this utility model, first, the construction time and labor cost of on-site masonry in the building are greatly saved through the prefabrication method in the factory; secondly, the strength of the wall is enhanced by embedding angle steels between the bricks, and then in cooperation with the reinforcing bars penetrating through the bricks and being welded to the bottom connecting piece, the pulling and fixing of the entire wall are realized, greatly improving the strength of the wall and making it not easily damaged by external forces and hoisting operations.

[0004] However, in the above-mentioned utility model, cavities are arranged on both sides of the brick for filling fireproof and heat-insulating materials. The cavities are through holes respectively arranged on both sides of the first protrusion. Each side through hole includes a strip-shaped through hole and circular through holes arranged on both sides of the strip-shaped through hole. After the wall is built, the strip-shaped through hole 18 of the upper brick and the circular through holes of the two lower bricks have a certain overlap in the vertical direction, and the two circular through holes of the upper brick and the strip-shaped through hole of the lower brick have a certain overlap in the vertical direction respectively. After the wall masonry is completed, multiple vertical fireproof and heat-insulating material filling cavities that penetrate from the top to the bottom of the wall and are not connected to each other will finally be formed for filling fireproof and heat-insulating materials.

[0005] Since the multiple formed vertical fireproof and heat-insulating material filling cavities are not connected to each other, when filling the fireproof and heat-insulating materials, it is necessary to fill a single vertical area from top to bottom multiple times, and finally form multiple non-connected and non-continuous fireproof and heat-insulating layers. In addition, due to the limitation of the cavity size in the brick, the thickness of the filled fireproof and heat-insulating layer is limited. In this way, not only the filling efficiency is low, increasing the labor intensity of workers, but also the fireproof and heat-insulating effect of the filled heat-insulating layer is poor, resulting in waste of material resources.

The multiple horizontal cavities in the horizontal direction and the multiple vertical cavities in the vertical direction are alternately communicated to form a reticular cavity for filling fireproof and heat-insulating materials.

[0026] This prefabricated fireproof and heat-insulating wall 10 greatly saves the construction time and labor cost of on-site masonry by means of prefabrication in the factory.

At the same time, through the reinforcing rib 15 passing through the angle steel 40, not only the strength of the wall 10 in the horizontal direction is improved, but also the reliability of the hoisting of the wall 10 is improved.

[0033] In some other embodiments, the "U" - shaped connecting component 142 provided on the angle steel 14 can be of other shapes, such as "C" - shaped, etc., for the "L" - shaped connecting and fixing member 122 on the fireproof and heat-insulating wall panel to pass through and hang; the "U" - shaped connecting component 142 can also be connected and fixed on the angle steel 14 by setting threaded holes on the angle steel 14 to improve the flexibility of hanging the fireproof and heat-insulating panel.

[0034] Furthermore, the prefabricated fireproof and heat-insulating wall 10 further includes a plurality of reinforcing bars 15 and a bottom connection and bearing plate 16; the plurality of reinforcing bars 15 are vertically connected to the bottom connection and bearing plate 16 and penetrate through the bricks 11 and angle steels 14 stacked up and down; the bottom connection and bearing plate 16 includes a plurality of bottom plates, the bottom plates are arranged staggeredly with the bricks 11, the reinforcing bar 15 on the right side of one bottom plate penetrates through the left half of one brick 11, the reinforcing bar 15 on the left side of another bottom plate penetrates through the right half of this brick 11, and the reinforcing bar 15 on the right side of another bottom plate penetrates through the left half of the adjacent brick 11.

[0036] Furthermore, the horizontal plane of the angle steel 14 is located in the mortar joint of the brick 11, and a second reinforcing bar perforation 141 is arranged on the horizontal plane of the angle steel 14 for the reinforcing bar to pass through.

[0037] Furthermore, first reinforcing bar perforations 111 penetrating through the upper and lower end faces of the brick 11 are correspondingly arranged on both sides of the top of the brick 11 for the reinforcing bar 15 to pass through; a filling steel pipe through hole 112 penetrating through the left and right end faces of the brick 11 is arranged on the side face of the brick 11 for the filling steel pipe 13 to pass through and be installed; a filling cavity 113 is further arranged inside the brick 11 and communicated with a filling steel pipe communication hole 131 for filling fireproof and heat-insulating materials.

Compared with the existing vertically connected cavity, the filling area is larger, and the area of the formed fireproof and heat-insulating layer is also larger; the network-connected method is more conducive to the diffusion filling of the fireproof and heat-insulating material in the cavity, greatly improving the filling efficiency. At the same time, compared with the existing filling method of the fireproof and heat-insulating material that can only be filled vertically at multiple points from top to bottom, the network-connected cavity can be filled horizontally or vertically, and the filling method is more convenient; the fireproof and heat-insulating material is one or more of rock wool, glass wool, foam glass, foam ceramics, foamed cement or closed-cell perlite, which has the functions of flame retardancy and heat preservation, can enhance the heat preservation, heat insulation and sound insulation performance of the brick 11, and the material of the fireproof and heat-insulating material is lighter and will not significantly increase the weight of the brick 11.
