Description

Technical Field

[0001] The utility model relates to the technical field of floor decking, in particular to a heat-insulating and sound-insulating floor decking capable of blocking sound bridges and a connecting piece thereof. Background Art

[0002] Traditional floor deck systems consist of a floor deck, a cast-in-place layer, a floating insulation and soundproofing layer, and a protective layer. Traditional floor decks utilize a concrete slab (or fiber cement board) as a base plate, and a steel truss as a load-bearing structure. This structure serves as support and bottom formwork during floor pouring. Rebar is tied to the base plate and concrete is poured to form the floor slab, making it a widely used structure. The steel truss is a truss constructed with steel bars as the top and bottom chords and web members, connected by resistance spot welding. The combined load-bearing slab in which the steel truss and base plate are connected by resistance spot welding is called a steel truss floor deck.

[0003] Traditional floor decking lacks insulation and soundproofing capabilities. To achieve these, sound insulation, thermal insulation, and protective layers must be added after the decking is completed. This results in traditional floor decking systems with numerous structural layers, complex construction processes, long construction periods, thick slabs, heavy loads, high construction costs, and the protective layer being prone to hollowing and cracking.

[0004] At present, the floor decking system with built-in thermal insulation and sound insulation mainly uses the hanging technology to hang the floor decking panel and the cast-in-place floor slab together, and fills the thermal insulation and sound insulation materials between the floor decking panel and the cast-in-place floor slab. Although this structure has good thermal insulation effect, due to the existence of connecting parts between the floor decking panel and the cast-in-place floor slab, the connecting parts become a vibration sound bridge for impact sound insulation, resulting in poor impact sound insulation effect of this type of floor decking system with built-in thermal insulation and sound insulation, and the required impact sound insulation effect cannot be achieved. Utility Model Content

[0005] The purpose of the utility model is to provide a sound-insulating floor decking and a connecting piece thereof that can block sound bridges, so as to solve the technical problems in the prior art in that the connecting piece between the floor decking panel and the cast-in-place floor slab becomes a vibration sound bridge for impact sound insulation, resulting in poor impact sound insulation effect of the floor decking system.

[0006] The utility model solves the above problems through the following technical solutions:

[0007] A heat-insulating and sound-insulating floor deck connector that blocks sound bridges is used to connect a steel truss and a reinforced steel mesh in a floor deck.

The forming assembly is connected to the reinforced steel mesh and is formed with a conduit with a through hole therein. The connecting rod passes through the conduit of the forming assembly, and one end of the connecting rod is limited in the conduit of the forming assembly by the elastic plug and has a movable amount, while the other end is connected to the connecting steel truss.

[0008] As a further improvement, the connecting rod is connected to the connecting steel bar truss by snapping or welding.

[0009] As a further improvement, the conduit of the forming assembly is arranged in the middle of the forming disk, and a steel bar clip connected to the reinforcing steel mesh is arranged on the forming disk in the same direction as the conduit.

[0010] As a further improvement, the steel bar clip is in the shape of an inverted "π", and is connected to the steel bars of the reinforced steel mesh through the opening deformation of the inverted "π".

[0011] As a further improvement, a plurality of ridges are formed at the connection between the steel bar clip and the reinforced steel mesh.

[0012] As a further improvement, the conduit is coaxially connected to a positioning tube away from the forming disk, and a connecting rod is provided through the conduit and the positioning tube.

DETAILED DESCRIPTION

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] Combined with attachment Figure 1-3 As shown, a thermal insulation and sound insulation floor deck connector for blocking sound bridges is used to connect the steel truss and the reinforced steel mesh in the floor deck, including: a forming component, a connecting rod and an elastic plug. The forming component is connected to the reinforced steel mesh, and a conduit with a through hole is formed on the forming component; the connecting rod passes through the conduit of the forming component, and one end is inserted into the conduit of the forming component by the elastic plug and has a certain amount of movement, and the other end is connected to the connecting steel truss. Through the movement of the connecting rod in the forming component, it plays a role in blocking the sound bridge.

[0028] Preferably, the connecting rod is connected to the connecting steel bar truss by snap fastening or welding, and when welding, the connecting rod is made of metal material. Of course, other methods can also be used for connection, and this embodiment does not limit this.

[0029] Specifically, in this embodiment, the connecting rod 2 includes: an integrally formed rod body 22 and a rod cap 21 , and the end of the rod body 22 away from the rod cap is configured to be pointed so as to smoothly pass through the molding component.

[0030] The forming assembly 1 includes: a forming disc 11, a conduit 12 and a positioning tube 13, wherein the positioning tube 13 is connected to one end of the conduit 12, and the other end of the conduit 12 is connected to the forming disc 11, and the forming disc 11, the conduit 12 and the positioning tube 13 are formed with a through hole for the rod body 22 of the connecting rod 2 to pass through; the diameter of the through hole formed in the conduit 12 is larger than the diameter of the through hole formed in the positioning tube 13, and the rod cap 21 is limited by the through hole formed in the conduit 12 so that the rod cap 21 can have a certain amount of movement therein. The elastic plug 3 is used to block the through hole formed in the conduit 12 to limit the rod cap 2 in the through hole formed in the conduit 12. Preferably, the elastic plug 3 is interference fit with the through hole formed in the conduit 12 to prevent the conduit from exiting the forming assembly 1.

[0031] Optionally, the conduit 12 and the positioning tube 13 are coaxially arranged in the middle of the forming disk 11, and the forming disk 11 is provided with no less than two steel bar bayonet holes 14 in the same direction as the conduit 12 and the positioning tube 13, which are connected to the reinforced steel mesh through the steel bar bayonet holes 14. In the present embodiment, the steel bar bayonet holes 14 are in an inverted "π" shape, and the steel bars of the reinforced steel mesh are installed in the inverted "π"-shaped opening of the steel bar bayonet holes 14, and are connected to the steel bars of the reinforced steel mesh through the deformation of the inverted "π"-shaped opening. Of course, it can also be set to other shapes, as long as it can connect the steel bars of the reinforced steel mesh. The purpose of setting the inverted "π"-shaped opening is to enable the steel bars of the reinforced steel mesh to be better installed in the steel bar bayonet holes 14, allowing the steel bars of the reinforced steel mesh to have a certain deformation or installation displacement. As an advantage, the inverted "π"-shaped opening of the steel bar bayonet holes 14 is formed with a plurality of ridges at the connection between the steel bars of the reinforced steel mesh and the steel bars to enhance friction and installation and fixing strength.

[0032] In an optional embodiment, the forming plate 11 is provided with a plurality of flow holes 15 for concrete to pass through, which are formed to avoid the guide tube 12 and the steel bar clip 14. These flow holes not only facilitate the passage of concrete but also save material. Of course, the forming plate 11 can be shaped not only as a strip but also as a circle, an ellipse, or other shapes, which are not limited in this application.

[0033] Under normal working conditions, the rod cap 21 is located at the top of the conduit 12, and under the limiting action of the positioning tube 13, it vertically connects the floor slab and the steel truss into a whole; under the action of the upper vibration force, the rod body 22 moves downward, breaks away from contact with the forming disk 11, is limited by the elastic plug 3, and plays the role of blocking the sound bridge.

[0034] Example 2:

[0035] Combined with attachment Figure 2-3As shown, a sound insulation floor deck for blocking sound bridges includes the connector in Example 1, concrete 4, reinforced steel mesh 5, a sound insulation layer 6 and a steel truss 7. The rod 22 of the connector passes through the sound insulation layer 6 and is connected to the steel truss 7. The connection method can be welding, hanging, clamping, etc., and the connection method is not limited; Figure 2-3 As shown, the rod body is positioned by passing through the steel frame formed by the lower chord and web members of the steel truss. The steel truss is then connected to the connector by snap fastening or welding. If welding is used, the rod body can be welded to the web members of the steel truss. The reinforcing steel mesh is set in the concrete and solidifies with the concrete to form a concrete slab. The thermal insulation layer 6 is located between the concrete slab and the steel truss 7.

[0036] Preferably, the depth of the connecting member is less than the thickness of the concrete slab, which is 6-100 mm. The size of the steel truss is determined based on the load-bearing conditions. The diameter of the steel bars in the reinforced steel mesh is 1-10 mm, and the spacing is 20-200 mm.

[0037] In this embodiment, the thermal insulation and sound insulation layer is composed of several insulation boards made of cross-linked polyethylene, polyethylene, flexible polyurethane, rubber and plastic, etc. The thickness of the insulation board is 6-50 mm, and the thermal insulation and sound insulation layer is composed of 1-5 layers of insulation boards, which is determined according to the impact sound insulation requirements.

[0038] The specific production process is:

[0039] A. First, a steel truss is formed by making the upper chord, lower chord and web members of steel bars and connecting them by resistance spot welding.

[0040] B. Connect the connector to the reinforced steel mesh, and make the rod of the connector pass through the thermal insulation layer and connect to the lower chord of the steel truss to form a three-dimensional steel grid structure; preferably, the connector is welded to the truss steel bars.

[0041] C. Spread the fine stone concrete evenly on the formwork.

[0042] D. Place one side of the reinforced steel mesh of the three-dimensional steel grid structure with the insulation and sound insulation layer on a uniformly spread fine stone concrete surface. Vibrate the formwork to evenly immerse the reinforced steel mesh into the fine stone concrete. Curing the concrete allows the thermal insulation fine stone concrete to develop strength, and the thermal insulation and sound insulation floor deck is now complete. During construction, this serves as the support and bottom formwork for pouring the concrete slab. Concrete is poured on top of it, forming a floor system with insulation and sound insulation. The rods can move up and down within the forming plate, disengaging from the plate and thus blocking sound bridges.

[0043] The floor decking of the present invention has thermal insulation and sound insulation functions and has good impact sound insulation performance. Under the same conditions, it can reduce the impact sound insulation by more than 15dB compared with traditional connectors, and can fully meet the requirement of impact sound insulation below 55dB. In addition, the floor decking is light in weight, only 1 / 6-1 / 3 of the traditional composite board, and has high strength. The bending load of its three-dimensional steel grid structure is higher than that of the composite board; the production cost is low, and its production cost per unit area is only 1 / 3-1 / 2 of that of the composite board; it is easy to make a whole board, solving the problems of board seams and post-pouring strips, as well as the problems of lifting and transporting the whole board. In addition, 3. The floor system using this floor decking reduces the number of floor structural layers, construction procedures and construction period, and construction costs; the floor system is thinner, and the floor thickness can be reduced by 3-8cm while meeting the relevant standard requirements; the load is reduced by more than 100kg per square meter, solving the quality defects of hollowing and cracking of traditional floor boards.

[0044] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
