Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a temporary auxiliary support structure for large-span floor decking. Background Technology

[0002] Large-span floor deckings deform during construction due to the weight of the concrete and operational vibrations, which can severely compromise their structural strength. Therefore, support is necessary to maintain structural stability during construction. Traditional support methods involve scaffolding, which are costly, inefficient, and time-consuming. Currently, a common method is the temporary support device for large-span floor deckings disclosed in CN221277369U, which uses support beams mounted on steel beams to support the floor decking. This method is simple in structure, convenient to construct, and low in cost. However, because the support device is placed on steel beams with relatively small flanges, it is highly susceptible to displacement due to vibration loads during floor decking construction, potentially even falling off, posing a significant safety hazard. This invention provides a temporary auxiliary support structure for large-span floor deckings to address these problems. Utility Model Content

The transverse beam spans between two floor deck steel beams. The support member is vertically mounted on the transverse beam. The longitudinal strut is located on top of the support member and is perpendicular to the transverse beam. The transverse span is equipped with fasteners, which are located at the ends of the transverse span and contact the floor deck steel beams.

[0005] Furthermore, the fastener includes a slot, a sleeve, and a top rod. The slot is located at the end of the transverse span beam, the sleeve is located on one side of the slot, and the top rod is located in the sleeve. The outer end of the top rod contacts the web of the floor deck steel beam.

[0006] Furthermore, the slot is a U-shaped slot that engages with the end face of the web of the transverse span beam, the sleeve is arranged parallel to the transverse span beam, and the top rod is threaded into the sleeve.

[0007] Furthermore, the support includes an adjusting seat and a support rod, the adjusting seat being disposed on the transverse crossbeam, and the support rod being disposed on the transverse crossbeam via the adjusting seat.

[0008] Furthermore, the adjusting seat includes a support plate and an adjusting bolt, the adjusting bolt is fixedly mounted on the support plate, the support plate is placed on the transverse crossbeam, the support rod includes a screw and a groove, the screw is threadedly connected to the adjusting bolt, the groove is located at the top of the screw, and the longitudinal support rod is located in the groove.

[0009] Furthermore, the transverse crossbeam is provided with intermittent insertion holes, and the lower part of the screw is located in the insertion holes.

[0010] Preferably, the transverse crossbeam is an I-beam, channel steel, or steel pipe.

[0011] The beneficial effects of this utility model are as follows: By setting fasteners, the transverse span beams are stably placed between the two floor slab steel beams, preventing the transverse span beams from shifting or even falling off due to vibration, thus effectively ensuring structural stability and construction safety. In addition, the support structure has the advantages of easy assembly and disassembly, which effectively improves construction efficiency, and can be reused repeatedly, reducing usage costs.

Therefore, they should not be construed as limitations on this utility model.

[0016] like Figure 1 , 2 As shown in Figures 3 and 4, a temporary auxiliary support structure for a large-span floor slab includes a transverse beam 1, a support member 2, and a longitudinal strut 3. The transverse beam 1 spans between two adjacent floor slab steel beams and is perpendicular to the floor slab steel beams. The end of the transverse beam 1 is located on the web of the floor slab steel beam. The support member 2 is vertically mounted on the transverse beam 1. The longitudinal strut 3 is located on top of the support member 2 to support the floor slab and is perpendicular to the transverse beam 1. The transverse beam 1 is equipped with a fastener 4, which is located at the end of the transverse beam 1 and contacts the floor slab steel beam. The fasteners 4 at both ends of the transverse beam 1 ensure that the transverse beam 1 is stably secured between the two adjacent floor slab steel beams, preventing displacement or detachment of the transverse beam 1 due to vibration during construction.

[0017] like Figure 2 , 4 As shown in Figure 6, the fastener 4 further includes a slot 41, a sleeve 42, and a top rod 43. The slot 41 is located at the end of the transverse beam 1 and is a U-shaped slot that engages with the end face of the web of the transverse beam 1, enabling convenient assembly and disassembly of the fastener 4. The sleeve 42 is located on one side of the slot 41 and is parallel to the transverse beam 1. The top rod 43 is threaded into the sleeve 42. The extension length of the top rod 43 can be adjusted by rotating the top rod 43, thereby enabling the top rod 43 to contact the floor slab steel beam. The outer end of the top rod 43 contacts the web of the floor slab steel beam.

[0018] The working principle of the fastener 4 is as follows: the fastener 4 uses the slot 41 to be fastened to the end of the transverse beam 1. The top rod 43 is adjustablely set in the sleeve 42 and is set perpendicular to the floor slab steel beam. When it is necessary to fasten the transverse beam 1, the adjusting top rod 43 of the fastener 4 located at both ends of the transverse beam 1 is extended outward. After the adjusting top rod 43 is extended, it abuts against the floor slab steel beam to fix the transverse beam 1.

[0019] Furthermore, the outer end of the top rod 43 is provided with a top plate, which contacts the web of the floor deck steel beam.

[0020] like Figure 1 , 3 As shown in Figures 4 and 5, the support member 2 further includes an adjusting seat 21 and a support rod 22. The adjusting seat 21 is disposed on the transverse crossbeam 1. The adjusting seat 21 includes a support plate 211 and an adjusting bolt 212. The adjusting bolt 212 is fixedly disposed on the support plate 211. The support plate 211 is placed on the transverse crossbeam 1. The support rod 22 is disposed on the transverse crossbeam 1 through the adjusting seat 21. The support rod 22 includes a screw 221 and a groove 222. The screw 221 is threadedly connected to the adjusting bolt 212. By changing the extension length of the screw 221 on the adjusting bolt 212, the height of the screw 221 can be adjusted. Then, the groove 222 is used to contact the longitudinal support rod 3 with the bottom surface of the floor deck and support the floor deck. The groove 222 is disposed at the top of the screw 221, and the longitudinal support rod 3 is disposed in the groove 222.

[0021] When installing the support member 2, first screw the screw 221 into the adjusting bolt 212 to connect the adjusting seat 21 and the support rod 22. Then, align the screw 221 with the insertion hole on the transverse crossbeam 1 and insert it. Then, place the adjusting seat 21 on the transverse crossbeam 1 to complete the installation of the support member 2 and the transverse crossbeam 1.

[0022] like Figure 3 , 4 As shown, further, insertion holes are provided at intervals on the transverse crossbeam 1, and multiple support members 2 are provided on each transverse crossbeam 1 as needed, or the setting position of the support members 2 is changed, and the lower part of the screw 221 is located in the insertion hole.

[0023] Furthermore, depending on the support requirements and length, the longitudinal struts 3 can be set one-to-one with the support members 2. In this case, the support members 2 support the middle of the longitudinal struts 3, or multiple support members 2 can be used to support a group of longitudinal struts 3.

[0024] Preferably, the transverse crossbeam 1 is an I-beam, channel steel, or steel pipe, and the longitudinal strut 3 is a steel pipe, timber, channel steel, or I-beam.

[0025] Preferably, the sleeve 42 is a threaded sleeve, welded to the groove 41, the top rod 43 is a screw rod, and the top plate is a round steel plate.

[0026] Preferably, the support plate 211 is a steel plate, the adjusting bolt 212 is welded to the support plate 211, and the support groove 222 is a channel steel, which is welded to the top of the screw 221.

[0027] In use, the support member 2 and the fastener 4 are first pre-installed on the transverse beam 1, keeping the height of the support rod 22 at its lowest and the extension length of the top rod 43 at its shortest. Then, the transverse beam 1 is hoisted, parallel to the floor slab steel beam. The operator rotates the transverse beam 1 so that both ends can be placed on the floor slab steel beam, and then lowers the transverse beam 1. Then, the transverse beam 1 is adjusted to be perpendicular to the floor slab steel beam, and the operator rotates the top rod 43 to extend it, thereby firmly locking the transverse beam 1 between the two floor slab steel beams. Then, the height of the support member 2 is adjusted to a suitable height, and the longitudinal support rod 3 is placed on the support member 2 to complete the installation.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
