[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-3 As shown, a steel structure assembled floor comprises a plurality of supporting steel sections 2 and a plurality of floor modules located at the same horizontal height, wherein the plurality of supporting steel sections 2 and the plurality of floor modules are arranged alternately; the floor module is composed of a plurality of templates located on the same straight line and connected in sequence, wherein both sides of the templates are clamped on adjacent supporting steel sections 2, and both sides of the supporting steel sections 2 are formed with clamping grooves corresponding to the templates of adjacent floor modules; end plates are formed at the ends of the supporting steel sections 2, and the end plates abut against the outermost templates of the floor modules; the template comprises a corrugated steel sheet 1 and a sound insulation layer 5 arranged in the corrugated steel sheet 1, and foam plates 7 in contact with the supporting steel sections 2 are arranged on both sides of the corrugated steel sheet 1, and rubber pads 6 in contact with the supporting steel sections 2 are also arranged at the corners of the corrugated steel sheet 1.

[0036] A plurality of support steels 2 and a plurality of floor slab modules form the required floor slab. A plurality of support steels 2 are arranged in parallel. Under the action of the support steels 2, the template is supported. The number of support steels 2 and the number of floor slab modules are set according to actual needs. A plurality of templates in the floor slab module are arranged along the length direction of the support steels 2, and the adjacent templates are offset from each other end to end. The number of templates is set according to actual needs and the length of the support steels 2.

[0037] The foam plate 7 and the rubber pad 6 are located at the connection between the corrugated steel plate 1 and the supporting steel 2, so that the foam plate 7 and the rubber pad 6 are pressed when the corrugated steel plate 1 and the supporting steel 2 are connected, so that a flexible buffer is provided between the corrugated steel plate 1 and the supporting steel 2, which has a shock-absorbing effect while increasing the friction between the corrugated steel plate 1 and the supporting steel 2, making the connection between the corrugated steel plate 1 and the supporting steel 2 more stable. The foam plate 7 also blocks the sound insulation layer 5, so that the sound insulation layer 5 has better stability during use.

[0038] The number of templates is set according to actual needs. Several templates connected in sequence are set between the relatively set supporting steels 2, and both sides of all templates are clamped with the relatively set supporting steels 2, the adjacent templates are butted against each other head to tail, the relatively set supporting steels 2 are set in parallel, and the relatively set supporting steels 2 clamp all the templates.

[0039] It includes a corrugated steel plate 1 with a wavy cross-section formed along the length of the plate and supporting steel sections 2 connected to both sides of the corrugated steel plate 1, wherein the corrugated steel plate 1 forms upper through grooves 1-1 and lower through grooves 1-2 arranged alternately in sequence along the length of the plate, and the lower through grooves 1-2 are filled with a sound insulation layer 5; the top and bottom of the corrugated steel plate 1 are respectively provided with an upper cement plate 3 and a lower cement plate 4 connected to each other, and both sides of the corrugated steel plate 1 are provided with foam plates 7 arranged oppositely; the upper cement plate 3, the lower cement plate 4 and the foam plates 7 arranged oppositely form a rectangular structure, and the side of the rectangular structure is clamped in the supporting steel section 2.

[0040] The corrugated steel sheet 1 is formed by roller cold bending, and the wave height of the corrugated steel sheet 1 is set according to actual needs. The supporting steel sections 2 on both sides clamp the same corrugated steel sheet 1, and multiple corrugated steel sheets 1 can be set on the same straight line between the supporting steel sections 2 on both sides.

[0041] The upper through groove 1-1 and the lower through groove 1-2 are vertically arranged with the supporting steel 2, so that the sound insulation layer 5 is vertically arranged with the supporting steel 2. When the supporting steels 2 on both sides support the same corrugated steel plate 1, the corrugated steel plate 1 is vibration-damped and buffered under the action of the sound insulation layer 5, so that the supporting steels 2 on both sides and the corrugated steel plate 1 have better stability.

[0042] An upward opening is formed at the top of the upper through groove 1-1, and the upper cement plate 3 connects all the upper through grooves 1-1, and the upper cement plate 3 blocks the upward opening of the upper through grooves 1-1. The size of the upper cement plate 3 is consistent with the horizontal cross-sectional size of the corrugated steel plate 1. The upper through grooves 1-1 are arranged equidistantly along the length direction of the corrugated steel plate 1, and the upper through grooves 1-1 serve as buffer deformation grooves for the corrugated steel plate 1.

[0043] A downward opening is formed at the top of the lower through groove 1-2, and the lower cement board 4 connects all the lower through grooves 1-2, and the lower cement board 4 blocks the upward opening of the lower through grooves 1-2. The lower cement board 4 supports the sound insulation layer 5. The size of the lower cement board 4 is consistent with the horizontal cross-sectional size of the corrugated steel sheet 1. The lower cement boards 4 are equidistantly arranged along the length direction of the corrugated steel sheet 1. The lower through grooves 1-2 serve as placement grooves for placing the sound insulation layer 5, and the size of the placement grooves corresponds to the size of the sound insulation layer 5.

[0044] The side surface of the upper through groove 1-1 is an inclined structure, and the side surface of the upper through groove 1-1 is inclined outward from bottom to top. Correspondingly, the side surface of the lower through groove 1-2 is inclined inward from bottom to top. At the same time, the sound insulation layer 5 is a rectangular structure, and the upper corners of the sound insulation layer 5 are against the side surface of the lower through groove 1-2, thereby achieving compression of the sound insulation layer 5, so that the sound insulation layer 5 has better stability during use.

[0045] Oppositely arranged snap-fitting grooves are formed on both sides of the upper cement board 3 and the lower cement board 4. The oppositely arranged snap-fitting grooves are located at both ends of the upper through groove 1-1 and the lower through groove 1-2. Rubber pads 6 filling the snap-fitting grooves are placed in the snap-fitting grooves.

[0046] When both sides of the corrugated steel sheet 1 are placed in the supporting steel 2, the two rubber pads 6 on the same side of the upper cement board 3 and the lower cement board 4 are simultaneously fitted with the inner wall of the supporting steel 2, thereby achieving a stable connection between the upper cement board 3, the lower cement board 4 and the supporting steel 2, and the distance between the upper cement board 3 and the lower cement board 4 is consistent with the size of the opening groove of the supporting steel 2. Under the action of the rubber pads 6, the upper cement board 3, the lower cement board 4 and the supporting steel 2 have a shock-absorbing effect.

[0047] The side edge of the rubber pad 6 is flush with the side edge of the corrugated steel plate 1 .

[0048] The relatively arranged foam plates 7 are located at both ends of the upper through groove 1-1 and the lower through groove 1-2. The upper through groove 1-1 and the lower through groove 1-2 are sealed under the action of the corrugated steel plate 1, the upper cement plate 3, the lower cement plate 4 and the relatively arranged foam plates 7. The length of the foam plates 7 is consistent with the length of the corrugated steel plate 1, and the foam plates 7 are against the supporting steel 2 during use to achieve a shock-absorbing effect.

[0049] The length of the sound insulation layer 5 is consistent with the length of the lower through groove 1 - 2 , and the two ends of the sound insulation layer 5 are flush with the side surfaces of the corrugated steel plate 1 .

[0050] Both ends of the upper through groove 1 - 1 and the lower through groove 1 - 2 are arranged toward the supporting steel sections 2 which are arranged oppositely.

[0051] An end plate 2 - 1 is provided at the end of the support steel 2 , and connection holes are formed on the end plate 2 - 1 on opposite sides of the support steel 2 . The connection holes on opposite sides of the support steel 2 are simultaneously connected to two adjacent corrugated steel plates 1 .

[0052] The actual installation process includes the following steps:

[0053] Step A: Select the length of support steel 2, the number of floor modules and the number of formworks according to site requirements.

[0054] Step B: The end plate is welded to the end of the supporting steel 2 in the factory. The end plate 2-1 is vertically arranged to the supporting steel 2, and the supporting steel 2 is connected to the middle of the end plate 2-1. The upper cement plate 3 and the lower cement plate 4 are prefabricated in the factory, and the corrugated steel plate 1 is roll-formed. The upper cement plate 3, the lower cement plate 4, the corrugated steel plate 1 and the welded supporting steel 2 are transported to the installation site together with the end plate 2-1.

[0055] Step C: Fix the end plate 2-1 to the wall with expansion bolts, and fix the connection holes on both sides of the end plate 2-1 to the wall with expansion bolts.

[0056] Step D: Attach the rubber pad 6 and the foam board 7 to the clamping groove of the supporting steel 2. The rubber pad 6 and the foam board 7 are attached to the clamping groove of the supporting steel 2 by glue, wherein the foam board 7 is attached to the middle of the clamping groove, and the rubber pad 6 is attached to both sides of the clamping groove. The connection between the foam board 7 and the rubber pad 6 is the corner of the clamping groove.

[0057] Step E: Insert the sound insulation layer 5 into the lower through groove 1-2 of the corrugated steel plate 1. The sound insulation layer 5 is alternately arranged along the direction of the alternating upper through groove 1-1 and the lower through groove 1-2. The sound insulation layer 5 is used to absorb the vibration generated by the corrugated steel plate 1, thereby playing a shock-absorbing role.

[0058] Step F: Place the upper cement board 3 and the lower cement board 4 on the upper surface and the lower surface of the supporting steel 2 respectively, and insert the upper cement board 3, the supporting steel 2 and the lower cement board 4 into the clamping groove of the supporting steel 2 as a whole.

[0059] When adjacent formworks are butted end to end, the upper cement boards 3 of the adjacent formworks are butted against each other, and at the same time, the lower cement boards 4 of the adjacent formworks are also butted against each other. The butting upper cement boards 3 and the butting lower cement boards 4 form a flat plate structure, which plays a sound insulation role. At the same time, the butting upper cement boards 3 and the butting lower cement boards 4 make the adjacent formworks have better stability.

[0060] Step G: Install the formwork in sequence along the length direction of the supporting steel 2, support the bottom of the formwork, install the supporting steel 2 on the other side of the formwork, attach the rubber pad 6 and the foam board 7 in the clamping groove of the supporting steel 2 in advance, and after the supporting steel 2 is clamped into the side of the formwork, fix the end plate 2-1 to the wall with the expansion bolts.

[0061] After several templates are clamped on one side of the supporting steel 2 and all the templates on one side of the supporting steel 2 are installed, the installed templates are supported by brackets to ensure that the templates are in a horizontal state, and the supporting steel 2 on the other side of the templates is installed.

[0062] Step H: Repeat steps DG until the entire floor is installed to complete the installation.
