Description
Technical Field
[0001] The present invention relates to the technical field of temporary supports for floor bearing plates, and particularly to a temporary support structure for inclined cable-stayed floor bearing plates with steel wire ropes. Background Art
[0002] Floor bearing plates, also known as composite floor slabs, floor panels or steel bearing plates, are essential supporting products in steel structure buildings. They are made by roll-forming and cold-bending galvanized steel sheets, presenting a wave-shaped cross-section such as V-shaped, U-shaped, trapezoidal or similar shapes. Floor bearing plates can be used as permanent formwork or as the lower tensile steel bars of the floor slab to participate in the stress calculation of the floor slab, and work together with concrete to form a composite floor slab. By using shear connectors to connect the steel plate and concrete, they work together to give full play to the inherent advantages of these two materials, having the advantages of light self-weight, high strength, large stiffness, convenient and fast construction, easy renewal, and being suitable for industrial production. Floor bearing plates are widely used in many places such as power plants, power equipment companies, car showrooms, steel structure factories, cement warehouses, steel structure offices, etc.
[0003] When the span of the floor bearing plate exceeds the upper limit value specified by relevant regulations, temporary supports need to be set at the mid-span of the floor bearing plate and removed after the concrete is poured. There is a way to use steel wire ropes for inclined cable-stayed temporary support of floor bearing plates. The specific method is as follows: First, an additional steel bar is added at the mid-span of the steel bar truss plate. The lower end of the steel wire rope is connected to the additional steel bar, and the upper end of the steel wire rope is connected to the lower flange of the upper steel beam. The steel wire rope and the lower flange of the steel beam are usually fixed with steel fasteners.
[0004] In related technologies, the larger the span of the floor bearing plate, the more steel wire ropes are usually used, and the more steel fasteners are used. Then, the number of steel fasteners that need to be installed and removed is also more. Especially during the process of removing the steel fasteners, ladders or mobile scaffolds are needed, and the ladders or mobile scaffolds need to be frequently moved, and the process of removing the steel fasteners is rather cumbersome.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Embodiment 1
[0024] A temporary support structure for a steel deck with inclined cable stays made of steel wire ropes. Referring to Figure 1 、 Figure 2 and Figure 3 ,it includes a steel beam 1 and multiple inclined cable stays made of steel wire ropes 2. Additional steel bars 3 are arranged along the length direction of the steel beam 1 inside the steel deck. It also includes a connecting piece and two fixing pieces. The two fixing pieces are both detachably connected to the steel beam 1, and there is a spacing between the two fixing pieces. One end of the connecting piece is connected to one fixing piece, and the other end is connected to the other fixing piece. One end of each of the multiple inclined cable stays made of steel wire ropes 2 is connected to the connecting piece, and the other end is connected with a turnbuckle. Multiple anchor rings are arranged at intervals on the additional steel bars 3, and each turnbuckle is connected to the corresponding anchor ring.
[0025] In this solution, during the stage of hoisting the steel beam 1 above the steel deck, two fixing pieces are pre-installed on the steel beam 1, and a connecting piece is connected between the two fixing pieces. Multiple inclined cable stays made of steel wire ropes 2 are also connected to the connecting piece. The multiple inclined cable stays made of steel wire ropes 2 are lowered above the steel deck. An additional steel bar 3 is added inside the steel deck, and then multiple anchor rings are welded at intervals on the additional steel bar 3. Subsequently, the turnbuckle lowered by each inclined cable stay made of steel wire rope 2 is hooked to the corresponding anchor ring. By adjusting the turnbuckle, each inclined cable stay made of steel wire rope 2 is tightened. During the concrete pouring stage and the concrete solidification stage, the multiple inclined cable stays made of steel wire ropes 2 are used to support the steel deck, which can prevent the steel deck from deflecting downward; after the concrete on the steel deck solidifies, the anchor rings are exposed above the concrete surface. The exposed parts of the anchor rings can be covered during the subsequent construction leveling stage. By setting up a ladder or a mobile scaffolding, the two fixing pieces on the steel beam 1 are removed. Since the multiple steel wire ropes are connected to the connecting piece between the two fixing pieces, the upper ends of the multiple steel wire ropes can be quickly removed, which is beneficial to reducing the operation of moving the ladder or the mobile scaffolding. The lower ends of the multiple steel wire ropes are connected to the anchor rings through the hooks of the turnbuckles, and can also be quickly disassembled, solving the problem that the process of disassembling the steel wire ropes in the prior art is relatively cumbersome.
[0026] More specifically, the connecting member includes a connecting steel wire rope 4, and both ends of the connecting steel wire rope 4 are connected to the corresponding fixing members through shackles; shackles are provided at the upper ends of multiple stay steel wire ropes 2, and the shackles at the upper ends of the multiple stay steel wire ropes 2 are sleeved on the connecting steel wire rope 4. The steel wire ropes are relatively light in weight, facilitating installation and transfer operations. In addition, the upper ends of the multiple stay steel wire ropes 2 are connected to the connecting steel wire rope 4 through shackles, and the position of the upper part of the stay steel wire rope 2 can be conveniently adjusted, so as to match the spacing of the lower anchor rings, and it is convenient to ensure that the stay length of the stay steel wire rope 2 is sufficient.
[0027] More specifically, the temporary support structure includes two parallel steel beams 1, which are respectively located on both sides directly above the additional steel bars 3. Two stay steel wire ropes 2 are connected to each anchor ring. Two fixing members are provided on the lower flanges of the two mutually facing sides of the two steel beams 1. A connecting member is provided between the two fixing members of the two steel beams 1. One stay steel wire rope 2 on each anchor ring is connected to any one of the connecting members, and the other stay steel wire rope 2 is connected to the other connecting member.
[0028] Embodiment 2
[0029] Based on Embodiment 1, in this embodiment, referring to Figure 1 、 Figure 2 and Figure 3 , the fixing member includes a steel clamping member and a fixing plate 5. Both steel clamping members are clamped on the lower flange of the steel beam 1, the fixing plate 5 is arranged on the corresponding steel clamping member, and connecting holes 6 are opened on both fixing plates 5. Both ends of the connecting member are connected to the corresponding fixing plates 5.
[0030] Specifically, the steel clamping member includes a C-shaped steel 7, the C-shaped groove of the C-shaped steel 7 is stuck on the lower flange of the steel beam 1, a clamping bolt 8 is threadedly connected to the upper part of the C-shaped steel 7, a rubber sleeve 9 is sleeved on the end of the rod part of the clamping bolt 8, and the rod part of the clamping bolt 8 passes through the C-shaped steel 7 and abuts against the lower flange of the steel beam 1.
[0031] In this solution, the C-shaped steel 7 can be detachably installed on the lower flange of the steel beam 1 through the clamping bolt 8 of the steel clamping member, which can not only fix the connecting steel wire rope 4, but also facilitate the disassembly of the connecting steel wire rope 4; in addition, a rubber sleeve 9 is sleeved on the clamping bolt 8, which can increase the friction between the clamping bolt 8 and the lower flange of the steel beam 1, and can further improve the connection stability between the fixing member and the steel beam 1, thereby ensuring the stability of the connecting steel wire rope 4.
[0032] Embodiment 3
[0033] Based on Embodiment 1, in this embodiment, referring to Figure 1 、 Figure 2 and Figure 3The length of the connecting steel wire rope 4 is greater than the spacing between the two fixed plates 5. The connecting steel wire rope 4 includes a first section steel wire rope 11 and a second section steel wire rope 12. One end of the first section steel wire rope 11 is connected to one end of the second section steel wire rope 12. An adjusting steel wire rope 10 is connected to the connecting portion of the first section steel wire rope 11 and the second section steel wire rope 12. The length of the adjusting steel wire rope 10 is longer than that of the second section steel wire rope 12. A basket bolt is provided at the end of the adjusting steel wire rope 10 away from the connecting steel wire rope 4. At this time, the first section steel wire rope 11 and the second section steel wire rope 12 are in a linear tensioned state, and the adjusting steel wire rope 10 is in a falling state.
[0034] In this solution, when the span of the floor deck is relatively not very wide, the solution of combining the first section of steel wire rope 11 and the second section of steel wire rope 12 is directly used (that is, the solution of using a shorter steel wire rope). At this time, the adjusting steel wire rope 10 is hung on the connecting steel wire rope 4 and is not used, and the connecting steel wire rope 4 is straightened for use; if the span of the floor deck is relatively wide, the number of inclined steel wire ropes 2 hung on the connecting steel wire rope 4 is large, and the tension at both ends of the connecting steel wire rope 4 is very large. At this time, the solution of combining the first section of steel wire rope 11 and the adjusting steel wire rope 10 (that is, the solution of using a longer steel wire rope) can be adopted, the basket bolt on the adjusting steel wire rope 10 is connected to the corresponding fixing plate 5, and the shackle between the second section of steel wire rope 12 and the corresponding fixing plate 5 is disassembled, thereby releasing the second section of steel wire rope. The connection between the rope 12 and the corresponding fixed plate 5, at this time, the first section of the wire rope 11 changes from a horizontal tensioned state to a middle drooping state, and the middle part of the adjusting wire rope 10 is also in a drooping state. When all the inclined wire ropes 2 are tensioned, the middle parts of the first section of the wire rope 11 and the adjusting wire rope 10 are in a drooping tensioned state. Since the angle between the first section of the wire rope 11 and the horizontal line increases, the angle between the adjusting wire rope 10 and the horizontal line increases, which is convenient for reducing the tension at both ends of the first section of the wire rope 11 and the adjusting wire rope 10, which is beneficial to reducing the load of the first section of the wire rope 11 and the adjusting wire rope 10, and is beneficial to increasing the safety of use of the first section of the wire rope 11 and the adjusting wire rope 10, and is beneficial to extending the service life of the first section of the wire rope 11 and the adjusting wire rope 10.
[0035] In other embodiments, the connecting wire rope 4 includes a first wire rope section 11 and a second wire rope section 12, and the first wire rope section 11 and the second wire rope section 12 are connected by a shackle or a rope clamp, and the corresponding end of the adjustment wire rope 10 is also connected to the above-mentioned shackle.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
