Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a hoisting tool for steel truss floor decking. Background Technology

[0002] Steel truss floor decking is a composite formwork that welds a steel truss to a galvanized profiled steel sheet bottom mold. During use, a crane is needed to move the steel truss floor decking to the designated position. The current operating method is as follows: First, multiple steel wire ropes are attached to the crane hooks, with hooks at the bottom. These hooks connect to the four corners of the steel truss. This connection method causes the middle of the steel truss floor decking to sink, leading to deformation of the bottom plate and affecting subsequent normal use. Second, multiple hooks are installed at the bottom of the frame. Because the frame shape is fixed, it cannot be used for different models of steel truss floor decking. If the frame is too large, it cannot hold all the hooks, and movement is inconvenient. If the frame is too small, the ends of the steel truss floor decking will sag. Utility Model Content

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 8 As shown, a hoisting tool for steel truss floor decking is characterized by comprising: a main beam 1, on which multiple through holes 102 are provided, the multiple through holes 102 being arranged along the length direction of the main beam 1; a horizontal tube 2, which is arranged perpendicularly to the main beam 1, the number of horizontal tubes 2 being two, the horizontal tube 2 having through holes 202, the horizontal tube 2 being detachably connected to the main beam 1 by connecting bolts, the connecting bolts passing through through holes 102 and through holes 202; a plug-in rod 3, on the inner side of both ends of the horizontal tube 2, the plug-in rod 3 being movably connected to the plug-in rod 3, the end of the plug-in rod 3 away from the horizontal tube 2 being provided with a hook 4; and lifting lugs 6, the upper end faces of both ends of the horizontal tube being fixedly provided with lifting lugs 6.

[0039] Multiple U-shaped plates 101 are fixedly mounted on the lower end face of the main beam 1. Each through hole 102 corresponds to one U-shaped plate 101. The spacing between the two vertical plates of the U-shaped plate 101 matches the width of the horizontal tube 2. The horizontal tube 2 is installed between the two vertical plates of the U-shaped plate 101. The connecting bolts pass through through hole 102 and through hole 202 from top to bottom and are threaded to the nuts. The vertical plates of the U-shaped plate 101 limit the horizontal tube 2, preventing relative rotation between the horizontal tube 2 and the main beam 1. By loosening the connecting bolts, the spacing between the two horizontal tubes 2 can be adjusted to suit the hoisting operations of different types of steel truss floor deck slabs.

[0040] The horizontal tube 2 has through holes 201 at both ends, and the connector rod 3 has multiple through holes 301 evenly spaced along the length of the connector rod 3. A limiting pin 7 is installed inside each through hole 201, passing through both through holes 201 and 301. A limiting ring 701 is fixed to the upper end of the limiting pin 7, with a diameter larger than that of the limiting pin 7. The limiting ring 701 prevents the limiting pin 7 from disengaging from the through hole 201. Pulling out the limiting pin 7 allows the connector rod 3 to be moved, adjusting the distance between the two hooks on the horizontal tube 2. This design is suitable for hoisting different types of steel truss floor slabs.

[0041] The hook 4 is fixedly connected to the connecting block 501 via the first connector 401. The end of the plug rod 3 away from the horizontal tube 2 has an installation groove 302 that matches the connecting block 501. The bottom of the installation groove 302 has a positioning groove 303 that corresponds to the first connector 401. The installation groove 302 has an opening at the end of the plug rod 3 away from the horizontal tube 2, and the positioning groove 303 has an opening at the end of the plug rod 3 away from the horizontal tube 2. The connecting block 501 is installed inside the installation groove 302, and the first connector 401 is installed inside the positioning groove 303.

[0042] The connecting block 501 has a limiting groove 502, which is perpendicular to the insertion rod 3. The two side walls of the mounting groove 302 have limiting holes 304 corresponding to the limiting groove 502. A limiting bolt 8 is installed in each limiting hole 304. One of the limiting holes 304 has an internal thread matching the limiting bolt 8. The limiting bolt 8 passes through the other limiting hole 304 and the limiting groove 502, and is threaded into the inner side of one of the limiting holes 304. The limiting bolt 8 limits the connecting block 501, preventing it from detaching from the mounting groove 302. The limiting bolt 8 is a handle bolt, which facilitates rotation to limit the connection block 501.

[0043] There are multiple connecting blocks 501, which are evenly arranged along the height direction. Adjacent connecting blocks 501 are connected by a second connector 5. By setting multiple connecting blocks 501, the distance between the hook and the plug rod 3 can be adjusted, which is suitable for hoisting operations of different types of steel truss floor decks.

[0044] The first connector 401 is a metal rod or steel wire rope. The second connector 5 is a metal rod or steel wire rope.

[0045] In some embodiments, the first connector 401 is a metal rod, and the second connector 5 is a steel wire rope.

[0046] When hoisting steel truss floor decks with easily deformable materials such as galvanized steel sheets as the base plate, the hook is connected to the lowest connecting block 501 through the first connecting piece 401. The lowest connecting block 501 is installed inside the installation groove 302. The base plate will not deform during the hoisting process, thus preventing damage to the base plate.

[0047] When hoisting steel truss floor decks with a base made of non-deformable materials such as wooden planks, the upper connecting block 501 is installed in the mounting groove 302.

[0048] Work process:

[0049] Loosen the connecting bolts and adjust the distance between the two horizontal tubes 2 according to the length of the steel truss floor deck. Then pull out the limiting pin 7 and adjust the position of the plug rod 3 according to the spacing of the steel truss of the steel truss floor deck. Then adjust the spacing of the two hooks and hang the four hooks on the upper chord steel bars of the steel truss. The hooks are located at the four corners of the steel truss floor deck. The main beam 1, horizontal tube 2, and plug rod 3 form a frame structure, which can reduce the lateral stress on the bottom plate, prevent the bottom plate from sagging and deforming in the middle, and is suitable for different types of floor decks.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
