Description

Technical Field

[0001] The present invention relates to the technical field of floor decking, in particular to a steel bar truss floor decking that is easy to support. Background Art

[0002] The production of steel truss floor decking is done by first welding three specifications of steel bars into steel trusses, and then using resistance spot welding to weld the steel trusses and bottom formwork into one. This can not only meet the assembly standards of prefabricated buildings, but also meet the quality requirements of floor and steel engineering construction.

[0003] For example, a support-free steel truss floor deck with announcement number CN217759484U includes a base plate, a tripod and a fixing rod, etc. There are two base plates in total, and the two base plates are symmetrical. Four fixing rods are connected to the left and right sides of the top of the two base plates by bolts, and the eight fixing rods on each base plate are fixedly connected with a tripod. The base plates can be spliced ​​and fixed in the form of a clamping mechanism, so there is no need to splice and fix the base plates by welding, which can improve people's efficiency in splicing and fixing the base plates. However, in the prior art, the floor deck is usually made of hot-dip galvanized corrugated steel plates with a thickness of 0.7 to 1 .0 mm, can be spliced ​​to adapt to different building needs and structural layouts. The existing splicing method is installed through sliding splicing, so if a splicing error occurs later, a certain space must be reserved before the floor decking can be removed. When it is necessary to remove and replace the floor decking between two floor deckings, it is necessary to remove the floor decking that is blocking on one side first, which is inconvenient to operate and reduces the installation efficiency of the floor decking. In addition, the splicing and fixation of the floor decking through spaced guide columns and blocks has limited splicing strength. During the subsequent pouring of concrete, the floor decking may become lateral unbalanced, reducing the use effect of the floor decking.

[0004] Therefore, a steel truss floor deck that is easy to support is proposed to solve the above-mentioned problems. Summary of the Invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] By setting up auxiliary structures and steel bar structures, before construction, after placing the position of the cast-in-place beam according to the design drawings, the frame is erected, and the height of the top supports on both sides of the structural beam is adjusted according to the elevation. After the adjustment is completed, two steel-clad wood are placed in the pallet, and support rods are installed between adjacent top supports. The connection parts at both ends of the support rods are fixed and installed by pins and mounting rings. Then, the reinforced beam formwork is laid on the frame. The beam formwork includes a beam bottom formwork and a beam side formwork, and a 1.5 mm wide double-sided tape is pasted on the top of the beam side formwork at the contact point with the floor decking body. After that, the laying of the floor decking body is started. The floor decking body protrudes 5 mm into the beam, and the contact point between the floor decking body and the beam side formwork is compacted so that the double-sided tape is fully adhered to avoid leakage. Secondly, a 50 mm long iron nail is used to fix this contact point to avoid displacement of the floor decking under external force.

[0031] By setting up a combined structure, the operator aligns the two floor deck main bodies, rotates the bolt, and screws the bolt downward into the sleeve. The bolt drives the limit rod to rotate, the limit rod drives the rotating cover to rotate, the rotating cover drives the rotating ring to rotate, the rotating ring drives the two pull ropes to wind, and the pull rope drives the movable plate to move toward the rotating ring. The movable plate drives the top block to slide inside the floor deck main body, and the movable plate will stretch the return spring.

The plug block drives the connecting plate to move, and the connecting plate compresses the auxiliary spring, so that the plug block is stuck in the slot on the adjacent floor deck main body, thereby completing the splicing of the adjacent floor deck main bodies. Since the bolt and the sleeve are threadedly connected, the bolt will not rotate after rotation, thereby improving the stability of the connection between the plug block and the slot;

[0032] By setting a locking structure, the operator rotates the top plate, and the top plate drives the screw rod to rotate, and the outer rod limits the threaded sleeve. The rotation of the screw rod causes the threaded sleeve to descend, and the threaded sleeve drives the insertion rod to descend, and the insertion rod is inserted into the socket. The descent of the insertion rod will also drive the mounting plate and the side plate to descend. The side plate will be deflected upward after being guided by the extrusion oblique block and extruded by the floor decking body, so that multiple side plates will be stretched apart, which is convenient for auxiliary pressing of adjacent floor decking bodies. The side plate drives the rotating shaft to rotate, and the rotating shaft acts on the torsion spring. During subsequent disassembly, the elastic force of the torsion spring will drive the rotating shaft and the side plate to rotate and reset. By inserting multiple insertion rods into the socket, it is convenient to firmly position the adjacent floor decking bodies, improve the splicing strength of the floor decking bodies, and reduce lateral imbalance during pouring of the floor decking bodies.

Secondly, a 50 mm long iron nail is used to fix this contact point to avoid displacement of the floor decking under external force.

[0054] A combined structure 4 is symmetrically arranged on both sides of the interior of the floor deck body 1. The combined structure 4 includes a driving unit and a connecting unit.

[0059] Example 2: Figure 6-Figure 9As shown, the operator aligns the two floor deck bodies 1 and rotates the bolt 43. The bolt 43 is screwed downward into the sleeve 42. The bolt 43 drives the limit rod 44 to rotate. The limit rod 44 drives the rotating cover 41 to rotate. The rotating cover 41 drives the rotating ring 46 to rotate. The rotating ring 46 drives two pull ropes 47 to wind. The pull ropes 47 drive the movable plate 48 to move toward the rotating ring 46. The movable plate 48 drives the top block 49 to slide inside the floor deck body 1.

[0060] The movable plate 48 will stretch the return spring 410, and the movement of the movable plate 48 will also squeeze the inclined surface of the plug block 414.

The rotation of the screw rod 52 causes the threaded sleeve 53 to descend, and the threaded sleeve 53 drives the insertion rod 55 to descend, and the insertion rod 55 is inserted into the insertion hole 56. The descent of the insertion rod 55 will also drive the mounting plate 58 and the side plate 510 to descend.

The operator aligns the two floor deck bodies 1 and rotates the top plate 51. The top plate 51 drives the screw rod 52 to rotate, and the outer rod 54 limits the threaded sleeve 53. The screw rod 52 rotates to make the threaded sleeve 53 drop, and the threaded sleeve 53 drives the insertion rod 55 to drop. Through multiple insertion rods 55, it is convenient to firmly position the adjacent floor deck bodies 1, and then rotate the bolt 43. The bolt 43 is screwed downward into the sleeve 42.
