DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a schematic diagram of the overall front view of the floor deck in the embodiment; Figure 2 It is shown that Figure 1 A schematic diagram of the structure enlargement in the middle; Figure 3 What is shown is a top view of a gusset plate in an embodiment;

[0023] The device includes:

[0024] Bottom template 10;

[0025] A steel truss, the steel truss comprises an upper chord steel bar 22, a lower chord steel bar 21 and a web steel bar 23, the lower chord steel bar 21 is symmetrically arranged, and the web steel bar 23 connects the upper chord steel bar 22 and the lower chord steel bar 21;

[0026] The gusset plate 30 includes a buckling portion 31, a plug-in portion 32 and a connecting rib 33. The buckling portions 31 are symmetrically arranged, a plurality of connecting ribs 33 are arranged between two buckling portions 31 and connect the two, the plug-in portion 32 is arranged at one end of the two buckling portions 31 away from each other, and the buckling portion 31 is bent downward and presses the lower chord steel bar 21 tightly into the bending groove;

[0027] The connecting piece passes through from the bottom end upward and is threadedly connected with the bottom template 10 and the plug-in portion 32 .

[0028] The buckling portion 31 of the buckle plate 30 is used to press the lower chord steel bar 21 of the steel bar truss to limit the position of the lower chord steel bar 21, and the detachable connection between the steel bar truss and the bottom template 10 is achieved by threading the provided connecting piece with the plug-in portion 32, and the connecting rib 33 connects the buckling portions 31 on both sides;

[0029] When the bottom formwork 10 is disassembled, the gusset plate 30 and the connecting piece can be disassembled by screwing the connecting piece, thereby facilitating the disassembly of the bottom formwork 10 on the steel bar truss floor deck.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a schematic diagram of the overall front view of the floor deck in the embodiment; Figure 2 It is shown that Figure 1 A schematic diagram of the structure enlargement in the middle; Figure 3 What is shown is a top view of a gusset plate in an embodiment;

[0031] The connector includes a threaded connection section 41 , which is a rod body with a threaded section on the outside. The plug-in portion 32 is provided with a threaded hole. The threaded connection section 41 passes through the bottom template 10 and is threadedly connected to the threaded hole of the plug-in portion 32 .

[0032] The connecting piece further includes a gripping section 43 , which is disposed at the bottom end of the threaded connecting section 41 .

[0033] The gripping section 43 facilitates the installation and removal of the connector. The connector can be held by hand or with the aid of common tools to be screwed into the bottom template 10 and the buckle plate 30 for connection, or screwed out to remove the bottom template 10 , which is quick and convenient.

[0034] The structure also includes a buffer pad 51 , which is sleeved on the threaded connection section 41 and located between the gripping section 43 and the bottom template 10 .

[0035] The buffer pad 51 is a rubber pad. On the one hand, it plays a buffering role to prevent the connecting parts from damaging the bottom formwork 10 during the connection process, affecting the secondary use of the bottom formwork 10; on the other hand, it plays a sealing role to block the assembly gap between the bottom formwork 10 and the connecting parts to prevent the steel truss floor deck from leaking during the pouring of concrete, thereby keeping the environment below the steel truss floor deck as clean as possible when pouring concrete, reducing subsequent cleaning work.

[0036] The connector also includes a tightening section 42, which is sleeved on the outside of the threaded connection section 41 at one end close to the gripping section 43. The buffer pad 51 is provided with a tightening groove corresponding to the tightening section 42, and the tightening section 42 is embedded in the tightening groove.
