Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a heat-insulating and sound-insulating floor deck and its floor slab system and production process. Background Art

[0002] As an important part of a building structure, the performance and structure of the floor deck floor slab system are directly related to the overall quality, use comfort, and construction cost of a building. The traditional floor deck floor slab system mainly consists of a floor deck, a cast-in-place layer, a floating heat-insulating and sound-insulating layer, and a protective layer. This system uses a concrete slab (or formed sheet) as the bottom plate, combined with a steel bar truss as the load-bearing structure. It not only serves as the support and bottom formwork during the floor slab pouring but also forms the final floor slab structure by tying steel bars and pouring concrete. This design realizes the functions of free support (or less support) and free formwork, and thus has been widely applied in various buildings.

[0003] However, the traditional floor deck floor slab system has revealed significant deficiencies in practical applications. First of all, the system has obvious defects in terms of heat insulation and sound insulation functions. Since the traditional floor deck itself does not have the ability of heat insulation and sound insulation, it is necessary to additionally add a floating sound-insulating layer, a heat-insulating layer, and a protective layer on its surface after the floor slab concrete is poured. This additional structural layer not only increases the complexity of the construction process, prolongs the construction period, but also causes an increase in the floor slab thickness and load, thereby increasing the construction cost. In addition, the protective layer is prone to problems such as hollowing and cracking during actual use, affecting the overall performance and service life of the floor slab.

[0004] Secondly, the traditional floor deck is not a whole-room slab in terms of structure, but is assembled by floor decks of different specifications. This assembly method will inevitably generate joints, and it is necessary to strengthen the treatment of the plate joints in the later stage. However, even after the strengthening treatment, there is still a risk of cracking in the plate joints, posing a potential threat to the integrity and durability of the floor slab.

[0005] In view of the above problems, in the prior art known to the inventor, there is a floor deck system with self-contained heat insulation and sound insulation. This system combines a steel bar truss on a heat-insulating composite board with a certain bending resistance function to form a floor deck with heat insulation and certain sound insulation functions. Although this structure has made remarkable progress in terms of heat insulation effect, since the floor deck panel is directly poured with the cast-in-place floor slab, it cannot effectively block the vibration sound bridge of impact sound insulation, resulting in poor impact sound insulation effect.

[0006] Therefore, how to provide a floor deck system that takes into account good heat insulation and sound insulation effects on the basis of ensuring integrity and durability is a technical problem to be solved. Summary of the Invention

[0007] The object of the present invention is to provide a heat-insulating and sound-insulating floor deck and its floor slab system and production process to solve the problems existing in the above-mentioned prior art, which can not only ensure the integrity and durability of the floor deck, but also reduce the vibration transmission between the first concrete layer and the second concrete layer, block the floor vibration from being transmitted to the panel, effectively block the impact sound bridge, and achieve an ideal impact sound insulation effect.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] The object of the present invention is to provide a heat-insulating and sound-insulating floor deck and its floor slab system and production process, so as to solve the problems existing in the prior art, which can not only ensure the integrity and durability of the floor deck, but also reduce the vibration transmission between the first concrete layer and the second concrete layer, block the floor vibration from being transmitted to the panel, effectively block the impact sound bridge, and achieve an ideal impact sound insulation effect.

[0042] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] As Figures 1 to 4 shown, the present invention provides a heat-insulating and sound-insulating floor deck, which includes a first skeleton 5, a second skeleton 3, a heat-insulating and sound-insulating layer 4 and a connecting member 1. Among them, the first skeleton 5 is used to be arranged in the first concrete layer 6, and the second skeleton 3 is used to be arranged in the second concrete layer 2. By arranging the first skeleton 5 and the second skeleton 3, the structural strength and durability of the first concrete layer 6 and the second concrete layer 2 can be enhanced. It should be noted that the heat-insulating and sound-insulating floor deck may not include the first concrete layer 6. The components except the first concrete layer 6 can be prefabricated into a heat-insulating and sound-insulating floor deck, which becomes the support and bottom formwork for pouring the concrete floor slab during construction. After pouring the concrete on the heat-insulating and sound-insulating floor deck, the first concrete layer 6 is formed, and thus a floor slab system with heat-insulating and sound-insulating functions is obtained. The heat-insulating and sound-insulating layer 4 is located between the first concrete layer 6 and the second concrete layer 2. In the prefabricated heat-insulating and sound-insulating floor slab, the heat-insulating and sound-insulating layer 4 is located at the top of the second concrete layer 2, and the first skeleton 5 is exposed. Thus, after pouring the first concrete layer 6, the first skeleton 5 is poured into the first concrete layer 6, and the heat-insulating and sound-insulating layer 4 is sandwiched between the first concrete layer 6 and the second concrete layer 2. On the one hand, the heat-insulating and sound-insulating layer 4 plays a role in heat insulation and sound insulation. On the other hand, the flexible and compressible characteristics of the heat-insulating and sound-insulating layer 4 itself enable it to be compressed or restored to its original shape, so that there is a movement margin between the first concrete layer 6 and the second concrete layer 2. The connecting member 1 includes a first connecting part and a second connecting part with relative movement margin. The first connecting part is connected to the first skeleton 5, and the second connecting part is connected to the second skeleton 3. Thus, the first skeleton 5 and the second skeleton 3 can be connected through the connecting member 1 and have a certain movement margin on the basis of maintaining the connection without detachment.

[0044] In the present invention, the first skeleton 5 and the second skeleton 3 are separated on both sides of the thermal insulation and sound insulation layer 4 by the connecting member 1. After pouring the first concrete layer 6 or the second concrete layer 2, an integral floor slab is formed. At the same time, due to the mobility of the connecting member 1 itself, the first concrete layer 6 and the second concrete layer 2 can have a movement margin, which can not only ensure the integrity and durability of the floor slab, but also reduce the vibration transmission between the first concrete layer 6 and the second concrete layer 2, block the vibration of the floor slab from being transmitted to the panel, effectively block the impact sound bridge, and achieve an ideal impact sound insulation effect.

[0045] In an embodiment, the first concrete layer 6 is arranged on the top of the thermal insulation and sound insulation layer 4, the second concrete layer 2 is located at the bottom of the thermal insulation and sound insulation layer 4, and the second concrete layer 2 and the thermal insulation and sound insulation layer 4 are used as the floor slab. The first concrete layer 6 can be cast on-site during construction. The first skeleton 5 is a steel bar truss, and the second skeleton 3 is a reinforcing mesh. After construction, in addition to the first concrete layer 6 and the second concrete layer 2 being on both sides of the thermal insulation and sound insulation layer 4, the steel bar truss and the reinforcing mesh can also be on both sides of the thermal insulation and sound insulation layer 4 respectively.

[0046] The number of connecting members 1 per unit area is determined by the mass per unit area of the fine aggregate concrete layer in a whole room, the support condition of the floor slab system, the construction load, and the quality of the cast-in-place concrete. The thickness of the thermal insulation and sound insulation layer 4 is determined by theoretical calculation based on the floor slab thermal insulation performance requirements and the impact sound insulation index. Taking the common specifications (the thickness of the floor slab panel (i.e., the fine aggregate concrete layer, the second concrete layer 2, the same below) is 20 mm, the thickness of the thermal insulation and sound insulation layer 4 is 20 mm, and the thickness of the cast-in-place concrete layer (i.e., the first concrete layer 6, the same below) is 120 mm) as an example for calculation. The hanging capacity of a single connecting member 1 is 2 kN (200 kg), and for safety in the calculation, the value is taken as 1 kN. Taking the thickness of the fine aggregate concrete layer in a whole room as 2 cm (0.5 kN), the thickness of the thermal insulation and sound insulation layer 4 as 2 cm (0.01 kN), the thickness of the cast-in-place concrete layer as 12 cm (3.0 kN), and the construction load as 3 kN / m 2 as an example, the total floor load is: 6.51 kN / m 2 , and the number of connecting members 1 required per square meter is 7.

[0047] In one embodiment, the connecting member 1 includes a forming component 11 and a connecting rod 12. Both the forming component 11 and the connecting rod 12 can be made of metal materials to have high strength and stability. The forming component 11 is connected to the reinforcing mesh. When connecting, it is mainly connected by snap connection, and can also be connected by welding, tying, etc.; the connecting rod 12 is connected to the steel bar truss. When connecting, it is mainly connected by welding, and can also be connected by tying, snap connection, etc. The forming component 11 is provided with a movable cavity 113 and a through hole communicating with the movable cavity 113. The aperture of the through hole is smaller than the inner diameter of the movable cavity 113. The through hole and the movable cavity 113 form a T-shaped structure for restricting the connecting rod 12 from detaching in the direction away from the forming component 11. The connecting rod 12 includes a rod body 121 and a limiting portion 122 connected to the rod body 121. The diameter of the limiting portion 122 is larger than the diameter of the rod body 121. The limiting portion 122 can be placed in the movable cavity 113. The rod body 121 can be connected to the lower chord of the steel bar truss by means of a buckle or welding to connect the steel bar truss with the connecting member 1. When installing the connecting rod 12 and the forming component 11, the rod body 121 is inserted into the movable cavity 113 in the direction away from the through hole (the opening described later). The rod body 121 penetrates through the through hole, and the limiting portion 122 is located inside the movable cavity 113. The limiting portion 122 has a certain movement margin in the movable cavity 113 and can limit the maximum margin to prevent the connecting rod 12 from coming out.

[0048] In one embodiment, the forming component 11 includes a clamping portion 111 and a conduit portion 112. The clamping portion 111 has a clamping groove for clamping the reinforcing mesh. For example, the clamping groove is circular / square and can be placed in the round / square hole of the reinforcing mesh. The conduit portion 112 has a pipe hole communicating with the through hole of the forming component 11. The rod body 121 of the connecting rod 12 penetrates through the pipe hole. The pipe hole can be used to keep the connecting rod 12 in a vertical state, so that the rod body 121 moves vertically in the pipe hole.

[0049] In one embodiment, an elastic plug 13 is further included. An opening for the limiting portion 122 to enter is provided at one end of the forming component 11 away from the through hole. The elastic plug 13 is used to block the opening to prevent concrete from entering the movable cavity 113 and the pipe hole of the conduit portion 112 during later pouring, and to prevent the connecting rod 12 from sliding out of the conduit portion 112. When the connecting rod 12 is vibrated, the elastic plug 13 can be compressed and the connecting rod 12 can move in the conduit portion 112, ensuring that the connecting rod 12 has a certain movement margin in the conduit portion 112.

[0050] In one embodiment, the reinforcing mesh includes one or a combination of two or more of welded steel bar mesh, woven steel bar mesh, alkali-resistant fiberglass mesh cloth, and basalt fiber mesh.

[0051] In one embodiment, the reinforcing mesh can be formed by arranging steel bars in a criss-cross pattern horizontally and vertically. The diameter of the steel bars is 1 mm to 10 mm, and the mesh size (or the spacing between the steel bars) is 10 mm to 200 mm; preferably, the diameter of the steel bars is 1 mm to 4 mm, and the mesh size (or the spacing between the steel bars) is 20 mm to 50 mm.

[0052] In one embodiment, reinforcing fibers are also provided in the fine aggregate concrete layer. The reinforcing fibers include one or more combinations of steel fibers, polypropylene fibers, basalt fibers, alkali-resistant glass fibers, and mullite fibers.

[0053] In one embodiment, the thickness of the fine aggregate concrete layer is 6 mm to 100 mm; preferably, it is 12 mm to 20 mm.

[0054] In one embodiment, the thickness of the thermal insulation and sound insulation layer 4 is 6 to 150 mm; preferably, it is 6 mm - 75 mm; more preferably, it is 20 mm to 50 mm.

[0055] In one embodiment, the thermal insulation and sound insulation layer 4 includes one or more combinations of foamed rubber and plastic materials, cross-linked polyethylene, polyurethane sponge, melamine sponge, glass fiber cotton, expanded polystyrene board, and extruded polystyrene board. The thermal insulation and sound insulation layer 4 preferably uses polyurethane sponge and melamine sponge, and more preferably uses compressed polyurethane sponge with a compression rate of 10% to 60%.

[0056] In one embodiment, the thermal insulation and sound insulation layer 4 is composed of a number of insulation boards made of cross-linked polyethylene, polyethylene, flexible polyurethane, rubber and plastic, etc. The thickness of the thermal insulation and sound insulation layer 4 is 6 mm to 150 mm, and the thermal insulation and sound insulation layer 4 is composed of 1 to 5 layers of insulation boards, which is determined according to the impact sound insulation requirements. In this embodiment, the thermal insulation and sound insulation layer 4 can be compressed by 0 to 60%; preferably, it is 20% to 30%.

[0057] Taking the polyurethane sponge as the thermal insulation and sound insulation layer 4, the thickness of the second concrete layer 2 (floor slab deck) is 20 mm, the thickness of the thermal insulation and sound insulation layer 4 is 20 mm, and the thickness of the first concrete layer 6 (cast-in-place concrete layer) is 120 mm as an example, the theoretical calculation of the thermal insulation performance of the floor slab system is shown in Table 1:

[0058] Table 1 Calculation Table of Floor Slab Thermal Insulation Performance

[0059]

[0060] For the determination of the impact sound insulation performance, referring to the "Architectural Acoustics Design Manual" edited by Che Shiguang (published in January 1991), the calculation formula for the improvement of the impact sound insulation of the floor slab is:

[0061]

[0062] Among them, f0 is the natural frequency of the elastic system composed of the surface layer and the cushion layer, with the unit of Hz;

[0063] f is the impact sound insulation frequency, with the unit of Hz;

[0064] E is the elastic modulus of the cushion layer material, with the unit of kg / m 2 ;

[0065] d is the thickness of the cushion layer material, with the unit of m;

[0066] m is the surface density of the surface layer material, with the unit of kg / m 2 .

[0067] By referring to relevant materials, it can be obtained that: the unit weight of cast-in-place concrete is 2500 kg / m 3 , and the surface density of 12 cm is 300 kg / m 2 . After testing, the elastic modulus of the polyurethane sponge thermal insulation and sound insulation layer 4 is 0.6 MPa to 1 MPa; through the above formula, the thickness of the first concrete layer 6 can be calculated as 120 mm, and the thickness of the second concrete layer 2 is 20 mm. The improvement amount of the impact sound of the thermal insulation and sound insulation layer 4 with different thicknesses of polyurethane sponge is shown in Table 2:

[0068] Table 2 Calculation Table of the Improvement of the Impact Sound Insulation of the Floor

[0069]

[0070] As can be seen from Table 2, the thicker the thickness of the thermal insulation and sound insulation layer 4, the greater the average improvement of the impact sound insulation, that is, the better the sound insulation effect.

[0071] Through experimental tests, the improvement of the impact sound insulation by compressing the polyurethane sponge is shown in Table 3:

[0072] Table 3 Table of the Impact Sound Insulation Effect of Different Compression Rates

[0073]

[0074] As can be seen from Table 3, different compression ratios have different effects on the improvement of the impact sound insulation, and the best effect is achieved when the compression ratio is 10% - 50%.

[0075] According to the records in the previous text, the thermal insulation and sound insulation floor bearing plate of the present invention can achieve the following technical effects compared with the prior art:
