Description

Technical Field

[0001] The invention relates to the technical field of steel structure house construction, and in particular to a floor structure of a multi-story steel structure house construction. Background Art

[0002] Steel structure buildings are being rapidly promoted in modern housing construction, and are recognized by users for their fast construction speed, less construction waste, and flexible changes in housing structure. With the promotion of high-rise steel structure houses, the floor slabs between floors are now mostly made by erecting steel beams in the room, laying steel purlins on the steel beams, laying steel plates on the purlins, and laying cement mortar on the surface of the steel plates. The floor slabs made in this way can meet the requirements in terms of strength. The floor structure of the existing steel structure house building still has the following problems: the purlins and steel beams, the purlins and the floor are fixed by welding or bolts, which results in a large amount of time required for welding and tightening bolts during the overall construction, resulting in a reduction in construction progress, and the existing purlins are all long rectangular steel bars, which increases the overall project cost. Therefore, a floor structure of a multi-story steel structure house building is proposed. Summary of the invention

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the present invention provides a floor structure of a multi-story steel structure house building, including Y-shaped purlins, a steel base plate, a sound insulation and heat insulation interlayer, a steel top plate and mounting parts. The lower surface of the steel base plate is provided with at least two C-shaped grooves parallel to each other, the opening of the C-shaped groove is located in the middle of the outer side of the C-shaped groove, and passes through both ends along the grooving direction of the C-shaped groove. The Y-shaped purlin is arranged with both ends facing upward and one end vertically facing downward. The C-shaped groove is clamped with both ends of the top area of ​​the Y-shaped purlin. Both ends of the Y-shaped purlin are self-lockingly mounted on the load-bearing steel beam through the mounting parts, and a sound insulation and heat insulation interlayer is provided between the steel base plate and the steel top plate.

[0004] Furthermore, at least two through-holes are provided on the steel bottom plate, a plug-in tube which is inserted into the plug-in hole is integrally connected to the sound insulation and heat insulation interlayer, and a plug-in tenon which is inserted into the plug-in tube is integrally connected to the lower surface of the steel top plate.

[0005] Preferably, the sound insulation and heat insulation interlayer comprises an aluminum foil layer, a flame retardant polyurethane foam layer, a flame retardant fiber mesh layer and a wear-resistant layer. The upper surface of the aluminum foil layer is integrally bonded with a flame retardant polyurethane foam layer, the upper surface of the flame retardant polyurethane foam layer is integrally bonded with a flame retardant fiber mesh layer, and the upper surface of the flame retardant fiber mesh layer is integrally bonded with a wear-resistant layer.

[0006] Preferably, the flame retardant polyurethane foam layer and the flame retardant fiber mesh layer are arranged in a porous structure.

[0007] Furthermore, the mounting part includes a U-shaped frame which is arranged in a right-angle U-shape and opened in a certain direction. The outer walls on both sides of the U-shaped frame are integrally connected with a V-shaped groove, which fits with the end of the Y-shaped purlin facing downward. A self-locking hole is opened inside the V-shaped groove, and a sliding self-locking block is arranged in the self-locking hole. A self-locking spring is integrally connected between the self-locking block and the end of the self-locking hole. The side of the self-locking hole in the telescopic area of ​​the self-locking spring is arranged to penetrate. The top of the self-locking block is arranged to have a rounded corner near the edge of the Y-shaped purlin, and the end surface of the Y-shaped purlin facing downward is provided with a groove which is engaged with the self-locking block.

[0008] Furthermore, a C-shaped groove is provided at the connection between two adjacent steel bottom plates.

[0009] Furthermore, the upper surface of the steel top plate is provided with anti-slip grooves. Beneficial Effects

[0010] Compared with the prior art, the present invention has a Y-shaped purlin with both ends facing upward and one end facing vertically downward when bearing load, so that the compressive strength of the Y-shaped purlin is improved, and the load-bearing can be better performed; the Y-shaped purlin has a simple structure and a low cost; the steel bottom plate can be quickly connected to the Y-shaped purlin by clamping the two ends of the top area of ​​the Y-shaped purlin through the C-shaped groove; the arrangement of the mounting parts makes it unnecessary to punch holes in the load-bearing steel beam when the Y-shaped purlin is connected to the load-bearing steel beam, so that the structure of the load-bearing steel beam is not damaged, thereby ensuring the structural strength of the load-bearing steel beam; and there is no need to tighten a large number of bolts during installation, thereby improving the construction speed.

[0011] The sound insulation and heat insulation interlayer is used for sound insulation and heat insulation, wherein the aluminum foil layer is used for reflecting heat and has a sound insulation effect, the flame retardant polyurethane foam layer is used for heat insulation and sound absorption, the flame retardant fiber mesh layer is used for heat insulation and sound absorption, and the wear-resistant layer is used to protect the surface of the sound insulation and heat insulation interlayer; by setting the flame retardant polyurethane foam layer and the flame retardant fiber mesh layer, the influence of the upper space temperature on the lower space temperature is reduced, that is, the loss of the upper space temperature is slowed down.

[0012] During installation, the opening of the U-shaped frame is clamped on the load-bearing steel beam, and the two ends of the downward end of the Y-shaped purlin are respectively clamped into the inside of the V-shaped groove, so that the downward end of the Y-shaped purlin pushes the self-locking block to shrink into the inside of the self-locking hole, so that the self-locking spring is compressed. When the groove is aligned with the self-locking block, under the elastic force of the self-locking spring, the end of the self-locking block is clamped into the inside of the groove to complete self-locking and achieve rapid installation. At the same time, when the Y-shaped purlin bends downward in the middle under huge pressure, because the end of the self-locking block is clamped into the inside of the groove, the self-locking block can generate a reaction force on the Y-shaped purlin to prevent the middle part of the Y-shaped purlin from bending downward, thereby greatly improving the overall compressive resistance.

The C-shaped groove 201 is clamped with both ends of the top area of ​​the Y-shaped purlin 1. Both ends of the Y-shaped purlin 1 are self-lockingly mounted on the load-bearing steel beam through the mounting member 5. Figure 3 , a sound insulation and heat insulation interlayer 3 is provided between the steel bottom plate 2 and the steel top plate 4; In specific implementation, when bearing load, the Y-shaped purlin 1 is arranged with both ends facing upward and one end facing vertically downward, so that the compressive capacity of the Y-shaped purlin 1 is improved, and it can bear load better. The Y-shaped purlin 1 has a simple structure and low cost. The C-shaped groove 201 is clamped with the two ends of the top area of ​​the Y-shaped purlin 1, so that the steel bottom plate 2 can be quickly clamped with the Y-shaped purlin 1. The setting of the mounting member 5 makes it unnecessary to punch holes in the load-bearing steel beam when the Y-shaped purlin 1 is connected to the load-bearing steel beam, so that the structure of the load-bearing steel beam is not damaged, and the structural strength of the load-bearing steel beam is guaranteed. There is no need to tighten a large number of bolts during installation, thereby improving the construction speed.

[0025] For further reference, Figure 3 , Figure 5 and Figure 6 At least two through-holes 202 are provided on the steel bottom plate 2, a plug-in tube 301 connected to the plug-in hole 202 is integrally connected on the sound insulation and heat insulation interlayer 2, and a plug-in tenon 401 inserted into the plug-in tube 301 is integrally connected on the lower surface of the steel top plate 4; In specific implementation, during quick installation, first install a number of Y-shaped purlins 1, then clip a number of steel base plates 2 onto the number of Y-shaped purlins 1, and then install the sound insulation and heat insulation interlayer 2 onto the steel base plates 2. During installation, insert the plug-in tube 301 into the plug-in hole 202, and then install the steel top plate 4 onto the sound insulation and heat insulation interlayer 2.

The upper surface of the aluminum foil layer 311 is integrally bonded with the flame retardant polyurethane foam layer 312, the upper surface of the flame retardant polyurethane foam layer 312 is integrally bonded with the flame retardant fiber mesh layer 313, and the upper surface of the flame retardant fiber mesh layer 313 is integrally bonded with the wear-resistant layer 314; In a specific implementation, the sound insulation and heat insulation interlayer 3 is used for sound insulation and heat insulation, wherein the aluminum foil layer 311 is used to reflect heat and has a sound insulation effect, the flame retardant polyurethane foam layer 312 is used for heat insulation and sound reduction, the flame retardant fiber mesh layer 313 is used for heat insulation and sound reduction, and the wear-resistant layer 314 is used to protect the surface of the sound insulation and heat insulation interlayer 3; The flame retardant polyurethane foam layer 312 and the flame retardant fiber mesh layer 313 are provided to reduce the influence of the upper space temperature on the lower space temperature, that is, to slow down the loss of the upper space temperature.

[0027] Preferably, the flame retardant polyurethane foam layer 312 and the flame retardant fiber mesh layer 313 are arranged in a porous structure; In specific implementation, through the setting of the porous structure, when noise is generated in the upper space, the sound is transmitted to the flame retardant polyurethane foam layer 312 and the flame retardant fiber mesh layer 313, and then the sound is silenced by the porous structure, thereby reducing the propagation of noise in the upper space. During production, several layers of flame retardant polyurethane foam layers 312 are made into a mesh, and several layers of meshed flame retardant polyurethane foam layers 312 are stacked and glued to form the entire flame retardant polyurethane foam layer 312, and the flame retardant fiber mesh layer 313 is the same; Glue used for bonding: flame retardant glue; After the production is completed, the flame retardant polyurethane foam layer 312 and the flame retardant fiber mesh layer 313 are both porous, and the gaps between the flame retardant polyurethane foam layer 312 and the flame retardant fiber mesh layer 313 are all flame retardant glue. Because the sound propagation speed in the flame retardant glue and the flame retardant polyurethane foam layer 312 and the flame retardant fiber mesh layer 313 is different, and the porous structure formed is irregularly arranged holes, the sound can be muffled after entering.

[0028] For further reference, Figure 7 and Figure 8 The mounting member 5 comprises a U-shaped frame 501 which is set in a right-angle U-shape and has an opening facing in a direction. The outer walls of both sides of the U-shaped frame 501 are integrally connected with V-shaped grooves 502, which fit with the end of the Y-shaped purlin 1 facing downward. A self-locking hole 503 is opened inside the V-shaped groove 502, and a sliding self-locking block 504 is arranged in the self-locking hole 503. A self-locking spring 505 is integrally connected between the self-locking block 504 and the end of the self-locking hole 503.

The edge of the top of the self-locking block 504 close to the Y-shaped purlin 1 is rounded, and the end surface of the Y-shaped purlin 1 facing downward is provided with a groove 101 engaged with the self-locking block 504. In the specific implementation, during installation, the opening of the U-shaped frame 501 is clamped on the load-bearing steel beam, and the two ends of the downward end of the Y-shaped purlin 1 are respectively clamped into the inside of the V-shaped groove 502, so that the downward end of the Y-shaped purlin 1 pushes the self-locking block 504 to shrink into the inside of the self-locking hole 503, so that the self-locking spring 505 is compressed. When the groove 101 is aligned with the self-locking block 504, under the elastic force of the self-locking spring 505, the end of the self-locking block 504 is clamped into the inside of the groove 101 to complete self-locking and achieve rapid installation. At the same time, when the Y-shaped purlin 1 bends downward in the middle under huge pressure, because the end of the self-locking block 504 is clamped into the inside of the groove 101, the self-locking block 504 can generate a reaction force on the Y-shaped purlin 1 to prevent the middle part of the Y-shaped purlin 1 from bending downward, thereby greatly improving the overall compressive resistance.

[0029] For further reference, Figure 3 and Figure 6 , the C-shaped groove 201 is opened at the connection between two adjacent steel bottom plates 2; In specific implementation, when adjacent steel bottom plates 2 are spliced, the Y-shaped purlin 1 can be supported on the edge of the steel bottom plates 2, so that the overall adaptability is improved and it can be used in more complex construction sites.
