DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 12 As shown, the present invention provides a spliced ​​steel structure floor support structure, which includes a side beam assembly 100 installed on a ring beam and fixed to a wall by driving expansion screws; a joist 200, which is erected and welded on the side beam assemblies 100 on both sides, and a cement slab is laid on the joist 200; a staircase 300, which is arranged on one side of the side beam assembly 100 and fixedly supports the side beam assembly 100 through the staircase 300; wherein the staircase 300 includes a diagonal bracing steel 301 and a vertical supporting steel 302 supporting the diagonal bracing steel 301, the top of the top support structure 400 is fixedly connected to the side beam assembly 100, and the bottom end of the top support structure 400 is supported on the outer wing plate of the diagonal bracing steel 301.

[0037] The diagonal bracing steel 301 and the vertical bracing steel 302 are combined fixed sleeve configurations, which can be adjusted and installed according to the height of the wing plate of the diagonal bracing steel 301. The installation space for the floor is saved, and the floor installation position is set under the diagonal bracing steel 301 of the inner staircase. And the assembly method is firm and fast.

[0038] like Figure 1 and Figure 3As shown, the side beam assembly 100 includes a main beam 101, a secondary beam 103 and a bracket 102 welded therebetween to form a triangular structural support, the bracket 102 is welded to the main beam 101 and the secondary beam 103, the main beam 101 is installed on the ring beam, and the secondary beam 103 is fixed to the wall by expansion screws.

[0039] The main beam 101, bracket 102 and auxiliary beam 103 are prefabricated welded integrated structures, which are directly erected and assembled. The main beam 101 is installed on the ring beam, and the auxiliary beam 103 is directly driven into the wall through expansion screws. The bracket 102 is supported between the main beam 101 and the auxiliary beam 103. Several triangular structural supports are formed, which have better anti-deformation ability in both longitudinal and transverse directions compared with the traditional single main beam support structure.

[0040] like Figure 3 As shown, the top support structure 400 includes a first set of steel 401 fixedly mounted on the secondary beam 103, a second set of steel 403 fixedly sleeved in the first set of steel 401 by a fixing member 402, and the bottom support of the second set of steel 403 is installed on the diagonal support steel 301.

[0041] The second set of steel 403 includes a second clamping block 4032 welded on the flange of the diagonal bracing steel 301 and a first clamping block 4031 meshed with the teeth therewith, and the first clamping block 4031 is connected to the body of the second set of steel 403;

[0042] The second set of steel 403 of each supporting structure 400 is fixedly connected to the adjacent second set of steel 403 via a connecting rod 406 .

[0043] The first set of steel 401 and the second set of steel 403 are both made of 1.5mm channel steel. The first set of steel 401 is pressed and elastically deformed by the fixing piece 402 to hold the second set of steel 403 inward to form a fixed sleeve structure. The second clamping block 4032 is welded on the diagonal bracing steel 301 at intervals, and the first clamping block 4031 is meshed downward on the second clamping block 4032 to form a fixed clamping structure. The first clamping block 4031 and the second set of steel 403 body can also be connected by a rotating connection to facilitate the clamping splicing following the tilt angle of the diagonal bracing steel 301.

[0044] like Figure 3 As shown, the top support structure 400 can only use the second set of steel 403 to replace the sleeve combination of the first set of steel 401 and the second set of steel 403.

[0045] Using the second set of steel 403 alone is one implementation method. The vertical support space upward along the diagonal bracing steel 301 is relatively small, so there is no need to use the first set of steel 401 and the second set of steel 403 in the upper part. Only the second set of steel 403 can be used, and the support effect can also be achieved.

[0046] like Figure 3-Figure 7 As shown, the fixing member 402 includes a stud 4023 that horizontally penetrates the first set of steel 401 and the second set of steel 403. Clamps 4021 are sleeved on both ends of the stud 4023 and are fastened to the first set of steel 401 through nuts 4022, thereby pressing the first set of steel 401 inwards to lock the second set of steel 403.

[0047] The inner surface of the first set of steel 401 and the outer surface of the second set of steel 403 are both set to be rough surfaces.

[0048] The clamping plate 4021 cooperates with the nut 4022 and the stud 4023 to clamp the first set of steel 401. The nut is tightened inwards to make the first set of steel 401 tightly hold the surface of the second set of steel 403. The inner surface of the first set of steel 401 and the outer surface of the second set of steel 403 are both roughened to increase the friction coefficient. The roughening treatment includes not only grinding treatment but also fine stripe treatment, so that the inner and outer stripes of the first set of steel 401 and the second set of steel 403 mesh to achieve a locking effect, so that they can be stable and not slip when facing longitudinal pressure.

[0049] like Figure 7 As shown, an elastic support member 404 is mounted inside the second set of steel 403 , and the installation position of the elastic support member 404 is flush with the fixing member 402 .

[0050] The head of the elastic support member 404 has an elastic tendency to expand outward, and it is stuck on the inner side of the second set of steel 403 to support its wing plate outward, thereby improving its elastic resistance to the outside, and is used to cooperate with the inwardly tightened fixing member 402 and the first set of steel 401 to closely contact and improve the stability of the locking.

[0051] like Fig.11 and Fig.12 As shown, the top end of the first set of steel 401 or the second set of steel 403 is connected to the subbeam 103 through a limit card 405, and the limit card 405 includes a first clamping position 4051 and a second clamping position 4052. The first clamping position 4051 passes through the subbeam 103 and is fastened thereto by bolts, and the second clamping position 4052 passes through the first set of steel 401 and is fastened thereto.

[0052] The limiter 405 is used to limit the position between the subbeam 103 and the first set of steel 401 / the second set of steel 403, ensuring that the first set of steel 401 / the second set of steel 403 vertically supports the side beam assembly 100. The first clamping position 4051 and the second clamping position 4052 are integral stamping parts, and the first clamping position 4051 is in the shape of an elastic clip, and the through-hole mounting bolts are locked on the subbeam 103. The second clamping position 4052 is locked on the first set of steel 401 by bolts and studs.

[0053] like Figure 8-Figure 10As shown, the top horizontal section flange of the diagonal bracing steel 301 mounts the secondary beam 103 via a clamping assembly 600 , and the clamping assembly 600 includes bolt fasteners and channel steel connectors.

[0054] There are multiple clamping assemblies 600, with the interval between two adjacent ones not exceeding 10 cm, which are used to assist the load at the shorter part of the end of the steel structure frame. The total length of this area is the platform at the end of the stairs, which is also the threshold of the room, and the length does not exceed 45 cm.

[0055] like Fig.10 As shown, the support beam 200 includes an I-beam 201 and a channel steel 202 laid vertically and horizontally. The channel steel 202 is provided with a rectangular groove engaged with the I-beam 201. A welding frame 203 is welded on the web of the I-beam 201 and the other end of the welding frame 203 is welded to the channel steel 202.

[0056] The welding frame 203 is used to improve the support strength of the channel steel 202. The channel steel 202 has a rectangular groove cut therein and is mounted on the I-beam 201 to reduce the assembly drop between the channel steel 202 and the I-beam 201. The remaining several millimeters of drop can be compensated by bonding mud, thereby increasing the support area of ​​the prefabricated cement board and improving the support strength and load capacity of the cement board. By welding the welding frame 203 between the I-beam 201 and the channel steel 202, the load strength of the channel steel 202 after the groove is compensated. Since the channel steel 202 is welded with the welding frame 203 at intervals for support, the two adjacent welding frames 203 are a separate support unit, and the various support units are connected to each other through the channel steel 202, which constitutes a combined and connected assembly system in terms of the steel structure frame itself, and the cement board also obtains a larger support surface due to the reduction of the installation drop, thereby improving the load capacity of the entire floor support structure.

[0057] like Figure 1 , 5 As shown in FIG. 6 , a support rod 2031 is provided on the inner side of the welding frame 203 , a scissor-type support assembly 500 is mounted on the support rod 2031 , and a sound insulation cotton 800 is supported above the scissor-type support assembly 500 ;

[0058] A ceiling assembly is suspended below the support beam 200 , and the I-beam 201 is downwardly connected with a hanging rod 701 , and a connecting piece 703 is mounted on the bottom end of the hanging rod 701 through a hanging piece 702 .

[0059] The scissor-type support assembly 500 is formed by hinged splicing of multiple cross-support assemblies, which can be adjusted synchronously, and then a cross-support assembly is installed in a grid unit respectively. A unit refers to a rectangular space formed by two adjacent I-beams 201 and channel steels 202, and the sound insulation cotton 800 can be installed in the rectangular space. The hinge of the scissor-type support assembly 500 protrudes to both sides and can be overlapped on the support rod 2031. Since the shape and size of each unit are equal. Therefore, after the scissor-type support assembly 500 is unfolded by synchronous telescopic expansion, it can also ensure that each cross-support assembly can be overlapped on each support rod 2031 to form a row of larger support planes. During assembly, the sound insulation cotton 800 is bonded or otherwise fixed to the bottom of the cement slab that has been paved, that is, each is set in each unit. After the scissor-type support assembly 500 is unfolded, it is installed in the support rod 2031 to support the sound insulation cotton 800 from the bottom to the top, and further reinforce it to prevent it from falling.

[0060] The working principle and use process of the present invention:

[0061] The main beam 101, bracket 102 and auxiliary beam 103 are prefabricated welded integrated structures, which are directly erected and assembled. The main beam 101 is installed on the ring beam, and the auxiliary beam 103 is directly driven into the wall through expansion screws. The bracket 102 is supported between the main beam 101 and the auxiliary beam 103. Temporarily support the other side 100, and weld 200 to 100, and then combine 100 and 300 on the other side through 400, remove the temporary support, and lay the prefabricated cement board.
