Description

Technical Field

[0001] The utility model relates to the technical field of building construction hoisting tools, and particularly relates to a hoisting device for a steel bar truss floor slab. Background Art

[0002] In the construction site of traditional steel structures, there are mainly two common hoisting methods for steel bar truss floor slabs. Both methods use two double-loop flat soft slings. One is the two-point fixed hoisting method, where one end is hung on the hoisting hook of the hoisting machinery, and the other end passes through the bottom truss of the packaged steel bar truss floor slab, and finally is bolted and connected to the end hanging on the hook by using a lifting ring / arch shackle; the other is the four-point fixed hoisting method, which is similar to the two-point fixed hoisting method. The difference is that the end passing through the bottom truss of the packaged steel bar truss floor slab is finally hung on the hook, thus forming the four-point fixed hoisting method. The two traditional on-site practices will cause varying degrees of deformation to the steel bar truss floor slab, resulting in the difficulty in ensuring the quality of the floor slab laying on-site. Summary of the Invention

[0003] The purpose of the utility model is to provide a hoisting device for a steel bar truss floor slab to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] One end of the barrier cross plate is detachably and fixedly connected to one side of the hoisting bracket. One end of the receiving plug plate is detachably and fixedly connected to the fitting surface of the barrier cross plate. An insertion plate docking slot for inserting the receiving plug plate is opened on the back surface of the barrier cross plate.

[0007] On one side of the hoisting bracket, a first mounting buckle and a second mounting buckle for docking with the hoisting belt are arranged from bottom to top.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] Example 1: Figures 1-5 As shown, the utility model provides a lifting device for a steel truss floor deck, including a truss 1 and a lifting assembly for lifting the truss 1, the lifting assembly including the truss 1, a blocking cross plate 2, a lifting bracket 3, a receiving plug plate 4 and a lifting belt 5.

[0026] One end of the blocking cross plate 2 is detachably fixedly connected to one side of the lifting bracket 3, and one end of the receiving plug plate 4 is detachably fixedly connected to the blocking cross plate 2 and its fitting surface. A plug plate docking slot 7 for receiving the plug plate 4 is provided on the back side of the blocking cross plate 2.

[0027] A first mounting buckle 14 and a second mounting buckle 15 for docking with the lifting belt 5 are provided on one side of the lifting bracket 3 from bottom to top.

[0028] A blocking cross plate installation groove 6 for inserting the blocking cross plate 2 is provided on one side of the hanging bracket 3 , and one end of the blocking cross plate 2 is fixedly connected to the inner wall of the blocking cross plate installation groove 6 by a cross plate fixing bolt 12 .

[0029] A reinforcing receiving block 10 for receiving the blocking transverse plate 2 is fixedly connected to one side of the lifting bracket 3 close to the blocking transverse plate 2 , and the upper surface of the reinforcing receiving block 10 overlaps with the bottom surface of the blocking transverse plate 2 .

[0030] The staff can adjust the installation position and number of the blocking cross plates 2 and the connecting plugs 4 according to the overall number of trusses 1. When the overall number of trusses 1 is relatively large, the center of gravity of the trusses 1 is relatively high, and the staff can increase the number of blocking cross plates 2 and connecting plugs 4. As the number of blocking cross plates 2 and connecting plugs 4 increases, the connecting plugs 4 on a single blocking cross plate 2 can be arranged equidistantly, thereby sharing the pressure of the upper chord steel bars. At the same time, the blocking cross plates 2 are arranged equidistantly on the lifting bracket 3, and in combination with the connecting plugs 4, the overall number of trusses 1 can be divided, reducing the weight borne by a single blocking cross plate 2, thereby improving the stability of the truss 1 during the lifting process.

[0031] Example 2: Figures 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a plug plate installation groove 9 is provided on the upper surface of one end of the receiving plug plate 4 close to the blocking cross plate 2, and the inner wall of the plug plate installation groove 9 is threadedly connected with a plug plate fixing bolt 11, and a cross plate installation groove 8 for docking with the plug plate fixing bolt 11 is provided on the bottom surface of the blocking cross plate 2, and one end of the receiving plug plate 4 is fixedly connected to the blocking cross plate 2 through the plug plate fixing bolt 11.

[0032] The number of the blocking horizontal plate mounting grooves 6 provided on one side of the hanging bracket 3 is not less than two. The number of the plug-in board docking slots 7 provided on the back of the blocking horizontal plate 2 is not less than two, and the number of the horizontal plate mounting grooves 8 corresponds to the number of the plug-in board docking slots 7.

[0033] A side mounting groove 13 for installing a first mounting buckle 14 is provided on one side of the lifting bracket 3. The end of the first mounting buckle 14 away from the lifting belt 5 is rotatably connected to the inner wall of the side mounting groove 13 through an axle rod. During the lifting process of the truss 1, multiple lifting belts 5 can be selected according to the overall number of pieces of the truss 1 to respectively connect with the first mounting buckle 14 and the second mounting buckle 15, thereby reducing the tension on a single lifting belt 5, thereby improving the safety of the overall lifting and extending the service life of the lifting belt 5.

[0034] The following is a detailed description of the working principle of the lifting device for steel truss floor decking.

[0035] like Figures 1-5 As shown, when in use, the four lifting brackets 3 are placed in pairs at appropriate positions on both sides of the truss 1, and then the two ends of the blocking cross plate 2 are respectively connected to 6 on the two lifting brackets 3, and then the blocking cross plate 2 and the lifting bracket 3 are fixed by tightening the cross plate fixing bolts 12. The blocking cross plate 2 on the other side of the truss 1 is operated in the same way, and then one end of the receiving plug plate 4 is inserted into the plug plate docking slot 7, and passed through the bottom of the upper chord steel bar of the single-piece steel truss in the truss 1, until both ends of the receiving plug plate 4 are overlapped on the blocking cross plate 2, and at this time, the upper surface of the receiving plug plate 4 overlaps with the bottom of the upper chord steel bar.

[0036] After the receiving plug board 4 is plugged in place, the receiving plug board 4 and the barrier cross board 2 are fixed by the plug board fixing bolt 11, and then the truss 1 can be integrally hoisted by using the lifting belt 5.

[0037] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or still includes elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element. The above has generally described the present utility model in detail, but on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
