[0029] Please Figures 1 to 6As shown, the composite thermal insulation and soundproof floor slab structure provided in this embodiment of the present invention includes: a base plate mechanism 100, with screws 400 inserted inside the base plate mechanism 100, and fasteners 200 connected to the base plate mechanism 100 via the screws 400; the base plate mechanism 100 includes a sound insulation board 1001, a fireproof thermal insulation board 1002, and a cement fiber board 1003; the bottom surface of the sound insulation board 1001 is connected to the fireproof thermal insulation board 1002, and the bottom end of the fireproof thermal insulation board 1002 is connected to the cement fiber board 1003; and the screws 400 respectively penetrate the sound insulation board 1001, the fireproof thermal insulation board 1002, and the cement fiber board 1003; and a truss assembly 300. The truss assembly 300 is welded to the top surface of the fastener 200. The fastener 200 forms a gap between the truss assembly 300 and the base plate mechanism 100. A support pole 500 is provided between the truss assembly 300 and the base plate mechanism 100. Through the combination of the sound insulation board 1001, the fireproof insulation board 1002, and the cement fiber board 1003, multiple functions such as sound insulation, fireproofing, and thermal insulation are integrated. The sound insulation board 1001 effectively blocks sound transmission, improving the building's sound insulation effect. The fireproof insulation board 1002 combines fireproofing and thermal insulation properties, ensuring building fire safety while reducing heat loss. The cement fiber board 1003 provides stable structural support. The connection method of the fastener 200 and screws 400 ensures a secure connection between all components. The gap formed between the truss assembly 300 and the base plate mechanism 100 enhances the structural strength of the floor decking and provides space for pipeline laying, etc. Compared with traditional floor decking, it is more functional and easier to install, reducing construction costs and time.

[0030] Specifically, the truss assembly 300 includes a first horizontal steel bar 3001, a second horizontal steel bar 3002, a third horizontal steel bar 3003, a first bent steel bar 3004, and a second bent steel bar 3005. The first horizontal steel bar 3001, the second horizontal steel bar 3002, and the third horizontal steel bar 3003 are respectively welded with the first bent steel bar 3004 and the second bent steel bar 3005, forming a stable spatial load-bearing structure. This structure can effectively distribute and bear the load on the floor, enhance the load-bearing capacity and deformation resistance of the floor deck, ensure the safety and stability of the floor deck during use, and adapt to the load requirements under different building environments and usage needs.

[0031] Specifically, the first horizontal reinforcing bar 3001, the second horizontal reinforcing bar 3002, and the third horizontal reinforcing bar 3003 are distributed in a triangular shape. Utilizing the stability principle of triangles, the truss assembly 300 has stronger structural stability. Furthermore, the first bent reinforcing bar 3004 and the second bent reinforcing bar 3005 are symmetrical to each other, ensuring balanced stress distribution and avoiding localized stress concentration. This embodiment of the invention further improves the reliability of the overall structure of the floor decking, enabling it to bear loads evenly and reducing the risk of deformation and damage.

[0032] Specifically, the fastener 200 includes a fastener body 2001. The top surface of the fastener body 2001 has an arc-shaped groove 2003 that matches the first horizontal steel bar 3001 and the second horizontal steel bar 3002. This groove can tightly fit the steel bars, making the connection between the truss assembly 300 and the fastener 200 more stable and effectively preventing the steel bars from shifting or loosening during the stress process.

[0033] Specifically, the bottom surface of the buckle body 2001 has a screw hole 2002 that engages with the screw 400, enhancing the connection strength between the buckle 200 and the base plate mechanism 100. After the screw 400 is screwed into the screw hole 2002, it can firmly fix the buckle 200 to the base plate mechanism 100, preventing the buckle 200 from falling off during the use of the floor decking and ensuring the integrity and stability of the overall structure of the floor decking.

[0034] Specifically, both the first bend of the reinforcing bar 3004 and the second bend of the reinforcing bar 3005 are designed in a corrugated shape. Compared with ordinary straight reinforcing bars, this increases the contact area with concrete and other pouring materials, improves the bond strength between the reinforcing bar and the pouring material, and enables the reinforcing bar and the pouring material to work together better, thereby enhancing the overall strength and durability of the floor deck. At the same time, the corrugated design can also disperse stress to a certain extent and reduce stress concentration.

[0035] Specifically, the sound insulation board 1001 is made of polypropylene, which has good sound insulation performance and weather resistance, and can play a stable sound insulation role for a long time. It is also lightweight, which can reduce the self-weight of the floor deck and reduce the load on the building structure. The fireproof and heat-insulating board 1002 is made of thermosetting composite polystyrene, whose fire resistance meets relevant standards and can effectively prevent the spread of fire. At the same time, it has excellent thermal insulation performance and reduces the energy loss of the building.

[0036] Specifically, the screw 400 is made of stainless steel, which has good corrosion resistance and can be used for a long time in complex environments such as humidity, acid and alkali without rusting or damage, ensuring the long-term stability of the connection between the various components of the floor deck.

[0037] Specifically, the support pole 500 includes a pole 5001, the bottom end of which is connected to a screw 5002. The bottom end of the screw 5002 is threadedly connected to the top surface of the base plate mechanism 100. The top end of the pole 5001 is inserted and connected to one side of the third horizontal reinforcing bar 3003. The outer wall of the pole 5001 is threadedly connected to a nut 5003. The top surface of the nut 5003 contacts the bottom surface of the third horizontal reinforcing bar 3003. Through the fixing action of the screw 5002 and the nut 5003, the pole 5001 is fixed and restricted between the truss assembly 300 and the base plate mechanism 100, thereby improving the stability between the two.

[0038] Example 1

[0039] High-rise residential projects require floor slabs to have high-efficiency sound insulation, heat insulation and fire resistance, while also shortening the construction period.

[0040] Base plate mechanism 100 installation:

[0041] Cut the sound insulation board 1001, fireproof insulation board 1002, and cement fiber board 1003 to the design dimensions and stack them in sequence, with the sound insulation board 1001 on top, the fireproof insulation board 1002 in the middle, and the cement fiber board 1003 at the bottom.

[0042] Stainless steel screws 400 are used to penetrate the three layers of plates, and the screws are distributed at reasonable intervals to ensure a stable connection of the base plate mechanism 100.

[0043] A clip 200 is installed on the top of the screw 400, and the screw hole 2002 on the bottom surface of the clip body 2001 engages with the screw 400 for fixation.

[0044] Truss assembly 300 installation:

[0045] The first horizontal steel bar 3001, the second horizontal steel bar 3002, and the third horizontal steel bar 3003 are arranged in a triangular pattern. The diameter and spacing of the steel bars are determined according to the load calculation.

[0046] Corrugated first bend steel bar 3004 and second bend steel bar 3005 are welded between the horizontal steel bars. The height of the bend steel bars is adapted to the thickness of the concrete pouring to enhance the bond between the truss and the concrete.

[0047] The truss assembly 300 is welded into the arc-shaped groove 2003 on the top surface of the fastener 200 to form an interval area for later pipeline laying.

[0048] Concrete pouring and its effect:

[0049] Pour concrete of appropriate strength, with a thickness covering the truss assembly 300 and the interval area.

[0050] Performance verification:

[0051] The 1001 sound insulation panel effectively blocks sound transmission and meets national standards.

[0052] Fireproof and heat-insulating board 1002 combines fireproof and heat-insulating properties, and meets energy-saving design requirements;

[0053] The construction period is shorter than that of traditional methods, and construction waste on site is reduced.

[0054] Example 2

[0055] Machine processing workshops need to withstand the loads of heavy equipment, and the floor slabs must have fireproof, soundproof and vibration-resistant properties.

[0056] 100-degree reinforced base plate mechanism:

[0057] It uses double-layer cement fiberboard 1003, with fireproof and heat-insulating board 1002 sandwiched in the middle, and sound insulation board 1001 on the top layer, which is fixed with stainless steel screws 400. The screw spacing is increased according to the thickness of the board.

[0058] Each layer of the board is connected by 400 screws to ensure the overall rigidity of the base plate mechanism 100.

[0059] Truss assembly 300 reinforcement design:

[0060] The horizontal reinforcing bars 3001 / 3002 / 3003 are large-diameter ribbed steel bars, distributed in an isosceles triangle structure, with the spacing optimized according to the load to form a stable stress system.

[0061] The corrugated first bend steel bar 3004 and the second bend steel bar 3005 have increased height and reduced spacing, which enhances the truss assembly 300 and the concrete's ability to work together to bear loads.

[0062] The arc-shaped groove 2003 of the fastener 200 is adapted to the size of the reinforcing bar to ensure that the truss assembly 300 fits tightly and is stable without shaking after welding.

[0063] A rubber vibration damping layer is added between the sound insulation board 1001 and the fireproof insulation board 1002 to further reduce the transmission of equipment vibration through the base plate mechanism 100.

[0064] Sufficient space is reserved in the interval area between the truss assembly 300 and the base plate mechanism 100 for laying cable trays and ventilation ducts, so as to avoid affecting the usable net height of the factory building.

[0065] Static load test: The floor slab bearing capacity meets the heavy load requirements of the industrial plant, and the truss components effectively distribute the load.

[0066] Fire resistance performance: The fire resistance rating of the 1002 fireproof insulation board meets the requirements of building fire protection codes such as GB50016.
