Description

Technical Field

[0001] The utility model relates to a building material, in particular to a prefabricated plate with a steel structure which can be spliced ​​and resists bending and cracking, and can be used for building partition walls, mobile house construction and temporary houses. Background Art

[0002] Prefabricated panels are prefabricated parts that are processed and formed in the prefabrication plant and can be transported to the construction site for direct installation. Existing prefabricated parts generally use plug-in docking methods and steel mesh keels to increase the bending strength of prefabricated panels, but there is no technical means to prevent cracking. The plug-in docking method can easily cause the plug-in interface of the prefabricated panel to be damaged prematurely, making the prefabricated panel unable to be reused; if the steel mesh keel is used, if the steel mesh is too thin, the bending resistance will be small, and if the steel mesh is too thick, although the bending resistance is increased, the weight and cost of the prefabricated panel will also be increased. Summary of the invention

[0003] In order to solve the problems existing in the above technologies, the utility model provides the following technical solutions.

[0004] A prefabricated panel with steel structure that can be spliced ​​and is resistant to bending and cracking, characterized in that it includes filler, fiber cloth, keel and binding straps, the keel is composed of a plurality of relatively parallel frame side panels and a frame cross arm vertically penetrating the frame side panels, the binding strap is wrapped around the outer surface of the keel in a single layer, the upper and lower sides of the keel are each attached with fiber cloth, and a layer of filler is poured around the fiber cloth and the keel; the prefabricated panel has two types of interfaces, one is a concave-convex interface prefabricated panel, and the other is a concave-concave interface prefabricated panel.

[0005] The skeleton side panel includes cross arm holes equidistantly arranged on its side, clamping blades arranged around the cross arm holes and side grooves arranged on the left side of the skeleton side panel. The skeleton cross arm passes through the corresponding cross arm holes in sequence to connect multiple skeleton side panels together to form a keel that intersects vertically and horizontally.

[0006] Each crossarm hole is provided with a clamping blade around it. Whenever the frame crossarm passes through the crossarm hole, the clamping blades around each crossarm hole clamp around the frame crossarm, so that the frame side plate will not slide back and forth on the frame crossarm.

[0007] The outside of the keel is wrapped with a layer of binding tape.

[0008] The binding strap is configured as a grid structure, and the grid structure is a grid woven from fibers, with a specification of 5-10 mm square grids. This grid structure will not affect the pouring of fillers into the keel, and can also enhance the stability of the keel.

[0009] The upper and lower surfaces of the keel are covered with fiber cloth, and the keel covered with fiber cloth is placed in a mold and filled with fillers, and the fillers penetrate into every space between the keel and the fiber cloth, and solidify to form a prefabricated board. The fiber cloth effectively prevents the prefabricated board from resisting upward and downward bending.

[0010] The fiber cloth is a grid-structured fiber cloth, which is solidified in the filler and can effectively prevent the filler from cracking.

[0011] The filler includes foamed cement or gypsum.

[0012] The left side of the prefabricated board is provided with an interface, and the right side is provided with a joint. The interface is an arc-shaped groove, and the joint is an arc-shaped ridge. When the prefabricated boards are used, the left side of one prefabricated board is docked with the right side of another prefabricated board. Since the arc-shaped interface and the joint are docked, the joint can be slid into the interface without precise alignment lines.

[0013] The utility model has the beneficial effects of being easy to assemble and disassemble and being able to be used repeatedly, effectively preventing the prefabricated board from cracking and improving the anti-bending ability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] like Figure 1 As shown, the utility model is a prefabricated plate with a steel structure that can be spliced ​​and resists bending and cracking.

[0026] like Figure 1 , 6 As shown in Figures 8 and 9, the utility model has two types of prefabricated panels with interfaces, one is a prefabricated panel 1 with a concave-convex interface, and the other is a prefabricated panel 2 with a concave-concave interface.

[0027] like Figure 3 As shown, the utility model includes a filler 11, a fiber cloth 12, a keel 13 and a binding band 14. The keel 13 is composed of a plurality of relatively parallel skeleton side panels 131 and a skeleton cross arm 132 vertically penetrating the skeleton side panels 131. The binding band 14 is wrapped around the outer surface of the keel 13 in a single layer to fix the skeleton side panels 131 so that they will not deform during the pouring process. The fiber cloth 12 is attached to each of the upper and lower sides of the keel 13, and a layer of filler 11 is poured around the fiber cloth 12 and the keel 13.

[0028] like Figure 4 and 7 As shown, the frame side plate 131 includes cross arm holes 1311 arranged at equal distances on its side, holding blades 1312 arranged around the cross arm holes, and side grooves 1313 arranged on the left side of the frame side plate. The frame cross arm 132 passes through the corresponding cross arm holes 1311 in sequence, connecting multiple frame side plates 131 in series to form a crisscross keel 13. Holding blades 1312 are arranged around each cross arm hole 1311. Whenever the frame cross arm 132 passes through the cross arm hole 1311, the holding blades 1312 around each cross arm hole 1311 hold the frame cross arm 132 tightly, so that the frame side plate 131 will not slide back and forth on the frame cross arm 132.

[0029] like Figure 3 and 4 As shown, in order to further enhance the stability of the keel 13, a layer of binding tape 14 is wrapped around the outside of the keel 13. During the pouring process of the filler 11, the skeleton side panel 131 will not be displaced on the skeleton cross arm 132 due to the external support force of the filler, resulting in uneven density of the keel and affecting the overall strength of the prefabricated panel.

[0030] like Figure 3 and 5 As shown, in order for the strap 14 not to affect the pouring of the filler 11 into the keel 13, the strap 14 is configured as a grid structure, and the grid structure is a grid woven from filaments of fiber-like items, and its specification is a square grid of 5-10 mm. This grid structure can also enhance the stability of the keel 13.

[0031] The fiber cloth includes organic fiber cloth and inorganic fiber cloth, the organic fiber cloth includes recycled fiber cloth, and the inorganic fiber includes glass fiber.

[0032] According to application requirements, the density of the binding bands can be adjusted to facilitate the pouring and penetration of the filler 11. When the structure of the keel 13 is not easily deformed during the pouring process, the binding bands can be removed.

[0033] like Figure 3 As shown, the fiber cloth 12 is attached to the upper and lower surfaces of the keel 13, and the keel 13 attached with the fiber cloth is placed in a mold to cast the filler 11. The filler 11 penetrates into every space between the keel 13 and the fiber cloth 12, and forms a prefabricated board after solidification. The setting of the fiber cloth effectively prevents the prefabricated board from resisting upward bending and downward bending.

[0034] The fiber cloth 12 is a fiber cloth with a grid structure, which is solidified in the filler 11 and can effectively prevent the filler from cracking.

[0035] The filler 11 includes foamed cement or gypsum. The filler 11 can also be replaced by other similar items.

[0036] like Figure 1 and 6 As shown, the left side of the prefabricated board is provided with a concave interface 16, and the right side is provided with a convex joint 15. The concave interface 16 and the right side are provided with a convex joint 15. The concave interface 16 is a circular arc groove, and the convex joint 15 is a circular arc convex ridge. When using the prefabricated board 1, the left side of a concave-convex interface prefabricated board 1 is docked with the right side of another concave-convex interface prefabricated board 1. Since the arc-shaped concave interface 16 is docked with the convex joint 15, the convex joint 15 can be slid into the interface 16 without precise alignment. When disassembling, just pull the two prefabricated boards in opposite directions. This docking method not only has good sealing performance, but also is not easy to damage the prefabricated board.

[0037] Different from the concave-convex interface prefabricated plate 1, another interface of the utility model is a concave-concave interface prefabricated plate 2, and the interfaces on the left and right sides of the concave-concave interface prefabricated plate 2 are respectively a concave interface 21 and a concave interface 22. In actual application, two concave-concave interface prefabricated plates 2 are tightly connected to make the concave-concave interface 21 and the concave interface 22 be assembled into a cylindrical space, and then foam concrete is poured therein to form a cylindrical column 23, and the concave-concave interface prefabricated plate 2 is sandwiched between the two cylindrical columns 23.

[0038] After the prefabricated panels are completed and before they are put into use, they must be cured for 20 days before they can be put into use.

[0039] The above are preferred embodiments of the present utility model. Any identical or similar structures that can be thought of by a person skilled in the art without creative work shall fall within the protection scope of the present utility model.
