[0002] The floor slab is a load-bearing component that divides the house into several floors vertically and transfers vertical loads such as people and furniture and the weight of the floor slab to the foundation through walls, beams or columns.

[0003] A lightweight floor decking board combining a strong ribbed steel mesh cement board and a steel truss is found with the announcement number CN214739136U. The lightweight floor decking board is composed of two parts: a strong ribbed steel mesh cement board and a steel truss. The bottom layer of the strong ribbed steel mesh cement board is a cement composite mortar layer, in which a metal mesh is laid. Ribs with a height of 30mm are provided on both sides of the wide side of the strong ribbed steel mesh cement board, and L-shaped steel strips are embedded in the ribs to increase the strength of the ribs. A plurality of steel bars are evenly distributed above the cement composite mortar layer, and both ends of the steel bars are placed in the ribs and fixed above the cement composite mortar layer. A plurality of steel trusses are evenly distributed above the strong ribbed steel mesh cement board, and the steel trusses are welded to the steel bars. The beneficial effects of the utility model are: its production process is simple, its installation is convenient and safe, and its transportation is convenient. In particular, the two materials are connected by welding, which is simple and easy, and the two materials can be transported separately, which greatly improves the transportation efficiency and reduces the transportation cost, which is conducive to large-scale promotion and use.

[0004] In response to the aforementioned related technologies, the inventors believe that the steel trusses in the aforementioned floor decks are connected to the steel bars on the reinforced steel mesh cement board by welding. This makes it difficult to quickly connect the two, severely reducing the installation efficiency of the steel trusses. Furthermore, the steel trusses are prone to misalignment during the welding process, thus affecting the overall installation effect. Therefore, we propose a lightweight floor deck that combines a reinforced steel mesh cement board with steel trusses. Utility Model Content

A limiting hole 16 is provided on the outer wall of the fixing block 15, and the position of the limiting hole 16 corresponds to that of the limiting block 9.

[0031] The utility model discloses a lightweight floor decking plate which is a combination of a strong-ribbed steel mesh cement plate and a steel bar truss. The bottom plate 1 is a cement mortar plate.

[0032] Example 2

[0033] Based on the first embodiment, Figure 1-3 As shown, the utility model is a lightweight floor decking plate combining a strong-ribbed steel mesh cement board and a steel truss. Ribs 4 are provided on both sides of the base plate 1. The ribs 4 and the base plate 1 form an integrated structure. The two ends of the steel plate 5 pass through the interior of the ribs 4, which can improve the stability of the steel plate 5.

[0034] The utility model is a lightweight floor decking plate combined with a strong-ribbed steel mesh cement board and a steel truss. The number of steel plates 5 is provided in plurality, and the multiple steel plates 5 are evenly distributed on the base plate 1. The number of fixing blocks 15 corresponds to the number of steel plates 5, which can provide a stable fixing effect for the installation of the steel truss 2.

[0035] The utility model is a lightweight floor decking plate combined with a strong rib steel mesh cement board and a steel truss. Guide grooves 7 are provided on the inner walls on both sides of the installation groove 6. Limiting mechanisms 8 are provided in the two guide grooves 7. The fixing blocks 15 can be limited from both sides, thereby improving the limiting effect of the fixing blocks 15.

[0036] The utility model is a lightweight floor decking plate combined with a strong-ribbed steel mesh cement board and a steel truss. The spring 11 is nested on the telescopic rod 10, and the spring 11 is press-fitted between the outer wall of the limit block 9 and the inner wall of the guide groove 7. Through the elastic force of the spring 11, after the fixed block 15 enters the interior of the installation groove 6, the limit block 9 is pushed to automatically enter the interior of the limit hole 16. Through the action of the spring 11, a certain thrust can always be provided for the limit block 9, so that it can always maintain a clamping relationship with the limit hole 16 to avoid separation between the two.

[0037] Example 3

[0038] Based on the second embodiment, Figure 1-5As shown, the utility model is a lightweight floor decking plate combining a strong-ribbed steel mesh cement board and a steel truss. The steel truss 2 includes two lower chord steel bars 12, one upper chord steel bar 13 and multiple web steel bars 14. The two lower chord steel bars 12, one upper chord steel bar 13 and multiple web steel bars 14 are welded and fixed to each other, and a fixing block 15 is welded to the bottom of the two lower chord steel bars 12, which can improve the overall strength of the steel truss 2.

[0039] The utility model is a lightweight floor decking plate combined with a strong-ribbed steel mesh cement board and a steel truss. Both the limit block 9 and the fixed block 15 are provided with inclined surfaces. The inclined surface on the limit block 9 is inclined upward, and the inclined surface on the fixed block 15 is inclined downward, which can facilitate the bracket to insert the fixed block 15 into the installation groove 6, thereby improving the overall operational convenience.

[0040] The utility model is a lightweight floor decking board combining a strong rib steel mesh cement board and a steel truss. The size and structure of the fixing block 15 correspond to those of the installation groove 6, which can prevent the fixing block 15 from shaking randomly after being inserted into the installation groove 6.

[0041] When the fixing block 15 is inserted into the inner portion of the installation groove 6, the fixing block 15 will first contact the limiting block 9. Since both the fixing block 15 and the limiting block 9 are provided with inclined surfaces, as the fixing block 15 is further inserted, the fixing block 15 will push the limiting block 9 into the inner portion of the guide groove 7. At this time, the spring 11 is in a compressed state. When the fixing block 15 is completely inserted into the inner portion of the installation groove 6, the limiting hole 16 will move to the position of the limiting block 9. At this time, the limiting block 9 loses the influence of external force, so it will enter the inner portion of the limiting hole 16 under the elastic action of the spring 11, thereby limiting the fixing block 15. At this point, the connection between the steel truss 2 and the base plate 1 is completed. In this way, the steel truss 2 can be quickly installed, and the overall operation is convenient. The steel truss will not have problems such as offset that affect the installation effect.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
