Referring to fig. 1 and fig. 2 in combination, an embodiment of the present invention provides a floor deck assembly, including: a plurality of building carrier plate bodies 10 that set up side by side, adjacent two in the building carrier plate body 10, one of them is provided with public rib 11, and the other is provided with female rib 12, female rib 12 is formed with spacing recess 121, the notch of spacing recess 121 deviates from to have public rib 11 building carrier plate body 10, public rib 11 with spacing recess 121 lock.

Taking the orientation shown in fig. 1 and 2 as an example, the plurality of floor support plate bodies 10 are arranged side by side along the horizontal direction, and the notches of the limiting grooves 121 are opened towards the right.

In the same building carrier plate body 10, the left side of plate body can set up female rib 12, and the right side sets up public rib 11, perhaps, the left and right sides of plate body all sets up female rib 12 or public rib 11, and the building carrier plate body 10 adjacent with it then corresponds sets up public rib 11 or female rib 12.

Referring to fig. 1, 2 and 4, in the technical solution of the present invention, the steel bar truss 30 and the connecting member are fixed together, the connecting member is fixed on the deck plate 10 of the deck plate assembly, and both the steel bar truss 30 and the connecting member are located on the upper surface of the deck plate assembly. Concrete wraps up steel bar truss 30 and coupling assembling, and the floor deck subassembly plays the effect of support, makes the concrete be located the upper surface of floor deck plate body 10. And after the concrete is formed, removing the floor support plate assembly. Therefore, the two adjacent floor support plate bodies 10 are buckled left and right, on one hand, in the construction stage, when concrete is poured, the notches of the limiting grooves 121 of the female ribs 12 are generally towards the horizontal direction, and the limiting can be carried out through the male ribs 11 in the up and down directions, so that the two adjacent floor support plate bodies 10 can be prevented from moving up and down, meanwhile, after the female ribs 12 of the male ribs 11 are buckled left and right, the floor support plate bodies 10 can be prevented from moving left and right, the generation of a local slurry leakage phenomenon can be avoided, and the flatness and the internal quality of a floor bottom die are ensured; on the other hand, in the construction completion stage, the mode that the female rib 12 of male rib 11 is buckled is favorable to demolising of floor deck subassembly.

The following examples are presented to further illustrate the utility model in conjunction with the detailed description.

In the embodiment of the present invention, the male rib 11 and the female rib 12 are formed by bending the floor deck plate 10 integrally.

The floor deck plate 10 includes, but is not limited to, galvanized sheet, galvanized alloy sheet, figured steel sheet, bamboo plywood, wood formwork, wood plastic sheet, injection molded sheet, aluminum alloy formwork, and profiled steel sheet. For example, when the floor deck plate 10 is a profiled steel sheet, it includes, but is not limited to, press forming with a galvanized sheet, a cold-rolled sheet, and the like. The floor support plate bodies 10 are buckled by the male ribs 11 and the female ribs 12 to form an integral structure, so that continuous supporting force can be improved. The profiled steel sheet can participate in the atress at the construction stage, avoids the deformation of floor support plate at the construction stage, consequently, can effectively improve the roughness effect of floor support plate bottom.

When adopting profiled sheet to be floor deck plate body 10, profiled sheet is disposable as removable die block, can satisfy relevant technical specification requirement, and the profiled sheet still has the incomplete value about raw and other materials cost% after demolising, for the removable die block of bamboo offset plate or the removable die block of aluminum alloy, profiled sheet has market competition economically. Moreover, the profiled steel sheet does not need to return to a factory to do a large amount of cleaning, detection, secondary processing and other work, so that the investment of production personnel is greatly reduced, the production procedures are reduced, the production efficiency is accelerated, and the production cost is reduced.

Wherein, the side of the floor bearing plate body 10, shown in fig. 2 as the right side, is provided with the male rib 11, the left side of another adjacent floor bearing plate body 10 is correspondingly provided with the female rib 12, the notch of the limiting groove 121 formed by the female rib 12 faces to the right, and the male rib 11 extends into the limiting groove 121 from the notch of the limiting groove 121. The male ribs 11 are fastened with the limiting grooves 121, which means that the male ribs 11 and the female ribs 12 are tightly matched, and one way to realize the locking is that the upper surface and the lower surface of each male rib 11 are respectively abutted against the upper groove wall and the lower groove wall of the limiting groove 121 to limit the male ribs 11 to move up and down in the limiting grooves 121, so that the two adjacent floor bearing plate bodies 10 are limited to move up and down. Specifically, the limiting groove 121 has two groove walls (an upper groove wall and a lower groove wall in the drawing) which are oppositely arranged, the two groove walls are distributed along the thickness direction of the floor plate body 10, and the male rib 11 can be abutted against the two groove walls.

Referring to fig. 2 again, in order to further increase the rigidity of the floor deck plate 10, the floor deck plate 10 has raised ribs 13 and recessed ribs 14 arranged at intervals, so as to enhance the rigidity of the floor deck plate 10, reduce the deformation, and improve the flatness of the floor bottom. The downwardly recessed portion of the floor deck plate 10 may be filled with an elastomeric bonding mortar or wall mud material, or a plugging material of similar properties.

The convex ribs 13 are ribs that are convex upward, and the concave ribs 14 are ribs that are concave downward with respect to the convex ribs 13. In one embodiment, the width of the convex rib 13 is smaller than that of the concave rib 14, so that a larger concave area is formed between two adjacent convex ribs 13, which is beneficial for more concrete to penetrate into the concave area and better wrap the connecting piece 21.

In one embodiment, the male rib 11 is connected to the side of the female rib 14 and protrudes from the protruding side of the male rib 13; the female rib 12 is connected to the side of the male rib 13 and protrudes on the side of the female rib 14 where it is recessed. In this embodiment, the male rib 11 protrudes above the female rib 14, so that the overall height of the male rib 11 and the female rib 14 is lower and close to the height of the male rib 13, thereby avoiding the protrusion of the male rib 11 above the whole floor deck plate body 10, avoiding the increase of the overall height of the floor deck plate body 10 and affecting the filling effect of concrete. Similarly, female rib 12 then protrudes in the below of fin 13, is equivalent to female rib 12 in the depressed area that fin 13 below formed, so female rib 12 and fin 13's overall height can be lower to be close to the height of fin 13, thereby can avoid female rib 12 to protrude in the below of whole building carrier plate body 10, avoided the increase of building carrier plate body 10 overall height.

Referring to fig. 2 and fig. 3, in an embodiment, the male rib 11 includes a limiting section 111 and a connecting section 112 connecting the limiting section 111 and the floor support plate 10, the limiting section 111 is fastened to the limiting groove 121, and the limiting section 111 is elastically abutted to two opposite groove walls of the limiting groove 121, an included angle α between the limiting section 111 and the floor support plate 10 is greater than 0 °, one end of the limiting section 111 connected to the connecting section 112 is close to the floor support plate 10, and the other end is far away from the floor support plate 10, so as to form an inclination angle. Wherein, the included angle α between the spacing segment 111 and the floor support plate body 10 can be 5 ° or 10 ° or the like.

In a practical way, for example, a metal plate such as a profiled steel plate, the male rib 11 formed by bending integrally has elasticity, and the limiting section 111 is formed like a resilient arm, and can be bounced up and down by a certain angle. Alternatively, the male rib 11 may be formed by machining a wooden template, for example, to have elasticity. When the position limiting section 111 extends into the position limiting groove 121 from the notch of the position limiting groove 121, the free end of the position limiting section 111 is squeezed by the upper and lower groove walls of the position limiting groove 121, so as to reduce the inclination angle between the free end of the position limiting section 111 and the floor support plate body 10, i.e. the position limiting section 111 gradually tends to be horizontal. This spacing section 111 and spacing recess 121's cell wall elasticity butt can be so that locking effect is better between public rib 11 and the female rib 12 to further improve vertical direction's restraint effect.

It is conceivable that the connecting section 112 is at least inclined with respect to the floor plate body 10, in a manner that the connecting section 112 extends vertically, and that it is smoothly connected with both the floor plate body 10 and the retaining section 111 by means of arc-shaped sections. Alternatively, the connecting section 112 is an arcuate section.

In the embodiment of the present invention, the shape of the male rib 11 has various shapes, and referring to fig. 2 and fig. 3 again, it is an achievable way that the male rib 11 is bent in a shape of a loop. Specifically, the male ribs 11 are bent in a manner similar to a paper clip or a mosquito coil. The male rib 11 may include a plurality of transverse segments 113, the plurality of transverse segments 113 are arranged at intervals along the thickness direction of the floor deck plate body 10, and the plurality of transverse segments 113 are connected in a winding manner, that is, the central transverse segment 113 at the middle is used as a center and sequentially connected outwards to form a clip structure. In this embodiment, the male rib 11 of the structure of returning to the shape, because there is the interval between two adjacent horizontal sections 113, can better provide the deformation space, then correspondingly the reverse elasticity after male rib 11 is extruded by female rib 12 is bigger, and both cooperations are inseparabler, can better restrict the removal of floor carrier plate body 10. In this embodiment, adjacent transverse segments 113 may be connected by arcuate segments.

Taking the male rib 11 with the zigzag structure as an example, the included angle α between the limiting section 111 and the floor deck plate 10 is greater than 0 °, which means that the transverse section 113 is inclined upward relative to the floor deck plate 10 in a direction away from the connecting section 112.

Referring to fig. 5 and 6, regarding the male rib 11, another way to achieve the purpose is that the male rib 11 includes a first section 114, a second section 115 and a hook 116 connected in sequence, the first section 114 is connected to the floor plate body 10, the first section 114 can be smoothly connected to the floor plate body 10 through an arc-shaped connecting section 112, the first section 114 is located at one side of the floor plate body 10 in the thickness direction, the second section 115 is bent in the direction away from the floor plate body 10 relative to the first section 114, and the hook 116 is bent in the direction facing the floor plate body 10. In this embodiment, the first section 114 is disposed substantially horizontally and is located on the upper side of the floor deck plate 10, the second section 115 extends upward, and the hook 116 is bent downward toward the right.

Taking the male rib 11 with the hook 116 as an example, the angle α between the limiting section 111 and the floor plate body 10 is greater than 0 °, which means that the first section 114 is inclined upward relative to the floor plate body 10 in a direction away from the connecting section 112. Thus, when assembling, the hook 116 abuts against the upper groove wall of the limiting groove 121, and the hook 116 pushes the first section 114 downwards after being extruded by the upper groove wall, so that the first section 114 tends to be horizontal until the first section 114 abuts against the lower groove wall of the limiting groove 121.

Referring to fig. 7 and 8, regarding the male rib 11, another way to achieve the object is that the male rib 11 includes a third section 117, a fourth section 118 and a fifth section 119, the third section 117 is connected to the floor plate body 10 and is located at one side of the floor plate body 10 in the thickness direction, the fourth section 118 is bent toward a direction away from the floor plate body 10 relative to the third section 117, and the fifth section 119 and the third section 117 are arranged in parallel. In this embodiment, the third segment 117 and the fifth segment 119 both extend in the transverse direction, the third segment 117 is located between the fifth segment 119 and the floor plate body 10, and the fourth segment 118 extends in the vertical direction. Where parallel arrangement refers to parallel or near parallel, in embodiments of the present invention, the fifth segment 119 is parallel to the third segment 117 or both are near parallel.

Taking the male rib 11 as an example, the included angle α between the limiting section 111 and the floor plate body 10 is greater than 0 °, which means that the third section 117 inclines upward relative to the floor plate body 10 in a direction away from the connecting section 112, the fifth section 119 may also incline in the same direction, or the fifth section 119 may be horizontally disposed, or the fifth section 119 may incline upward in a direction away from the fourth section 118, so that the upper groove wall of the limiting groove 121 presses the free end of the fifth section 119 downward, and the free end gradually tends to be horizontal. Thus, when the assembly is performed, the fifth section 119 abuts against the upper groove wall of the limiting groove 121, and the fifth section 119 pushes the third section 117 downward after being squeezed by the upper groove wall, so that the third section 117 tends to be horizontal until one end (i.e., one end connected to the fourth section 118) of the third section 117 tilted upward abuts against the lower groove wall of the limiting groove 121.

Referring to fig. 2 again, in the embodiment of the present invention, the female rib 12 includes a first bending section 122 and a second bending section 123, the first bending section 122 is connected to the floor support plate 10 and the second bending section 123 respectively, the second bending section 123 is disposed in parallel with the floor support plate 10, a limiting groove 121 is formed between the floor support plate 10, the first bending section 122, and the second bending section 123, and the limiting groove 121 is substantially a U-shaped groove structure. In addition, the first bending section 122 is bent relative to the floor support plate body 10 and extends substantially vertically, and the first bending section 122 may be parallel to the up-down direction or inclined at a certain angle relative to the up-down direction. The second bending segment 123 is bent relative to the first bending segment 122, wherein parallel arrangement means parallel or approximately parallel, and in the embodiment of the present invention, the second bending segment 123 is parallel or approximately parallel to the floor plate body 10.

Specifically, in this embodiment, the floor support plate body 10 forms an upper groove wall of the limiting groove 121, the second bending section 123 forms a lower groove wall of the limiting groove 121, and the male rib 11 is abutted against the floor support plate body 10 and the second bending section 123 respectively. In addition, the male rib 11 may abut against the first bent section 122 to restrict displacement in the left-right direction.

Further, different forms of connecting assemblies may be used depending on different needs. Referring to fig. 9 to 15, in an embodiment, the connecting assembly includes: a connecting member 21 and a supporting member 22.
