Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a truss floor deck with high rigidity and thermal insulation and sound insulation functions. Background Technology

[0002] In modern building construction, floor decking, as a crucial component of the building's horizontal structure, directly impacts the building's quality and user experience. Traditional truss floor decking designs often prioritize load-bearing capacity, resulting in insufficient stiffness and a tendency for significant deformation, affecting the building's stability and durability. Furthermore, traditional floor decking frequently lacks effective thermal and sound insulation measures, failing to meet energy-saving requirements in cold regions and struggling to block noise in densely populated public buildings or locations with high noise levels, thus reducing the building's comfort and usability. With the construction industry's increasing demands for energy conservation, environmental protection, and residential comfort, developing a truss floor decking that combines high stiffness with thermal and sound insulation functions has become an urgent problem. Therefore, this paper proposes a high-stiffness truss floor decking with thermal and sound insulation capabilities. Utility Model Content

[0003] The purpose of this utility model is to solve the above problems by proposing a truss floor deck with high rigidity and thermal insulation and sound insulation functions.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-rigidity truss floor deck with thermal insulation and soundproofing functions, comprising a concrete base slab and a plurality of trusses cast into the concrete base slab, characterized in that: it further comprises concrete ribs cast into the top of the trusses and including the top of the trusses, and a thermal insulation board connected to the bottom of the concrete base slab; the trusses include at least one support member, a lower rib provided on the bottom side of the support member, a middle rib provided on the middle side of the support member, and at least one upper rib provided on the top of the support member, wherein the top of the support member may optionally be provided with outwardly bent ears, the ears being cast into the concrete ribs.

[0005] Preferably, the lower reinforcement bar is cast into the concrete base slab along with the bottom of the support member, and the lower reinforcement bar is completely embedded in the concrete base slab to form an anchoring connection.

[0006] Preferably, when there is only one top reinforcement bar, it is either entirely cast inside the concrete rib or entirely exposed outside the concrete rib; when there are multiple top reinforcement bars, at least one is cast inside the concrete rib.

[0007] Preferably, the support is a wave-shaped support or is composed of several discontinuous V-shaped support members.

[0008] Preferably, the bottom surface of the concrete base plate and the top surface of the thermal insulation board can be connected by a bidirectional groove or a flat surface.

[0009] Preferably, the cross-sectional shape of the concrete rib can be square, rectangular, circular, or elliptical.

[0010] The beneficial effects of this utility model are as follows: By setting concrete ribs and pouring them into the top of the truss, the truss is wrapped inside to form a longitudinal connection support, which significantly improves the bending stiffness and load-bearing capacity of the floor deck. During construction, it can also reduce the number of support columns for the floor deck, reduce construction time and lower construction costs. By setting the thermal insulation layer, heat transfer is effectively prevented, reducing building energy consumption and meeting building energy conservation standards. At the same time, the thermal insulation board and the overall structure of the floor deck work together to effectively block the transmission of sound, creating a quiet and comfortable environment inside the building, which is suitable for various places with high noise control requirements. By setting the folded ears, the top of the support is bent outward to form folded ears, and the folded ears are poured into the concrete ribs, increasing the contact area and connection strength between the truss and the concrete ribs, further improving the overall stiffness of the floor deck.

[0018] The following description, in conjunction with the accompanying drawings, further illustrates the high-rigidity truss floor decking with thermal insulation and soundproofing functions described in this utility model.

[0019] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Participation Figure 1-6 As shown, this embodiment of a high-rigidity truss floor deck with thermal insulation and soundproofing functions includes a concrete base slab 1 and several trusses 2 cast into the concrete base slab 1. The key feature is that it further includes concrete ribs 3 cast into the top of the trusses 2 and enclosing the top of the trusses 2, and a thermal insulation board 4 connected to the bottom of the concrete base slab 1. Each truss 2 includes at least one support member 21, a lower rib 22 located on the bottom side of the support member 21, a middle rib 23 located on the middle side of the support member 21, and at least one upper rib 24 located on the top of the support member 21. The top of the support member 21 may optionally have outwardly bent ears 211, which are cast into the concrete ribs 3. Through the setting of the concrete ribs 3, the trusses 2 are cast into the top of the trusses 2 and enclosed within the trusses 2. The longitudinal connection support significantly improves the bending stiffness and load-bearing capacity of the floor deck. During construction, it also reduces the need for supporting columns on the floor deck, thus reducing construction time and costs. By setting the thermal insulation layer 4, heat transfer is effectively prevented, reducing building energy consumption and meeting building energy conservation standards. At the same time, the thermal insulation board 4 and the overall structure of the floor deck work together to effectively block sound transmission, creating a quiet and comfortable environment inside the building, suitable for various places with high noise control requirements. By setting the folded lug 211, the top of the support member 21 is bent outward to form the folded lug 211, and the folded lug 211 is poured into the concrete rib 3, increasing the contact area and connection strength between the truss 2 and the concrete rib 3, further improving the overall stiffness of the floor deck.

[0022] Participation Figure 1-6As shown, the lower reinforcement 22 is cast into the concrete base slab 1 along with the bottom of the support member 21, and the lower reinforcement 22 is completely embedded in the concrete base slab 1 to form an anchoring connection; this anchoring connection method makes the truss 2 firmly connected to the concrete base slab 1, enhancing the stability and load-bearing capacity of the floor deck.

[0023] Participation Figure 1-6 As shown, when there is one top reinforcement bar 24, it is either entirely cast inside the concrete rib 3 or entirely exposed outside the concrete rib 3. When there are multiple top reinforcement bars 24, at least one is cast inside the concrete rib 3. The arrangement of the top reinforcement bars 24 is relatively flexible, and the stress performance of the floor deck and the connection method with other components can be reasonably adjusted according to the actual engineering needs.

[0024] The support member 21 is either a wave-shaped support member or composed of several discontinuous V-shaped support members. When the support member 21 is a continuous wave-shaped support member, the wave-shaped support member is welded with the lower rib 22, middle rib 23, and upper rib 24 to form a truss 2, increasing the continuity of the truss 2 and increasing the bending stiffness of the floor deck. When the support member 21 is composed of discontinuous V-shaped support members, the V-shaped support members can be welded with the lower rib 22, middle rib 23, and upper rib 24 to form a truss 2, reducing the amount of material used in the support member 21 and lowering material costs. The design of the wave-shaped or V-shaped support member greatly enhances the stiffness of the truss 2, so that the deformation of the floor deck is significantly reduced when subjected to large loads, improving the stability and safety of the building structure and extending the service life of the floor deck.

[0025] The bottom surface of the concrete base plate 1 and the top surface of the thermal insulation board 4 can be connected by a two-way tongue and groove or a flat surface. The two-way tongue and groove connection can increase the friction and interlocking force between the two, making the connection tighter and effectively preventing the thermal insulation board 4 from shifting. The flat surface connection has the advantages of simple construction and low cost, and can be selected according to specific construction conditions and project requirements.

[0026] The cross-sectional shape of the concrete rib 3 can be square, rectangular, circular, or elliptical; it can be flexibly selected according to the span, load, and construction conditions. Square and rectangular concrete ribs are convenient for formwork production and are suitable for standardized construction. Circular concrete ribs can reduce stress concentration and are suitable for dynamic load scenarios. Elliptical concrete ribs can balance stiffness and material usage and optimize economy.

[0027] The support member 21 is one or a combination of steel bars, sheet metal parts, or structural steel.

[0028] Example 1: When the truss 2 is equipped with two support members 21, firstly, a folded lug 211 is folded out at the top of the support member 21, then the lower rib 22 and the middle rib 23 are welded to one side of the support member 21, and the top of the two support members 21 are welded together using the upper rib 24. The folded angles of the folded lugs 211 of the two support members 21 are opposite and the bottoms are separated, so that the two support members 21 form a symmetrical triangular structure, which effectively increases the overall stability of the truss 2. During the fabrication of the floor deck, it effectively prevents the truss 2 from tilting and increases the compressive strength. The upper rib 24 is welded on the symmetrical line of the two support members 21. After the concrete rib 3 is poured, the upper rib 24 is exposed outside the concrete rib 3.

[0029] Example 2: When the truss 2 is provided with two support members 21 and several top ribs 24, firstly, a folded ear 211 is folded out at the top of the support member 21, then the bottom rib 22 and the middle rib 23 are welded to one side of the support member 21, and several top ribs 24 are used to weld the tops of the two support members 21 together. The folded angles of the folded ears 211 of the two support members 21 are opposite and the bottoms are separated, so that the two support members 21 form a symmetrical triangular structure. The top ribs 24 are welded on the symmetrical line of the two support members 21. After the concrete rib 3 is poured, at least one top rib 24 is poured into the concrete rib 3, and the rest are exposed outside the concrete rib 3.

[0030] Example 3: When a support member 21 is provided on the truss 2, the lower reinforcement 22 and the middle reinforcement 23 are first accurately welded to both sides of the support member 21 according to the design dimensions and positions. Then, the upper reinforcement 24 is welded to the top of the support member 21. The bottom of the support member 21 is poured into the concrete base plate 1, and the upper reinforcement 24 is poured into the concrete rib 3 along with the top of the support member 21, forming an I-shaped structure with the concrete base plate 1 and the concrete rib 3.

[0031] In the pouring process of this utility model, the thermal insulation board 4 is first placed at the bottom layer, and the concrete base slab 1 is poured on the thermal insulation layer 4. The thermal insulation board 4 and the concrete base slab 1 can be connected by adhesive or mechanical anchors. Before the concrete base slab 1 initially sets, the fabricated truss 2 is accurately placed according to the design spacing and position. A vibrating device is placed on the truss 2 to vibrate the bottom of the truss 2 into the concrete base slab 1, ensuring that the bottom reinforcement 22 is completely embedded in the concrete base slab 1. The vibration is compacted to ensure a firm connection. Then, a template is installed on the top of the truss 2, and the concrete ribs 3 are poured, so that the top of the truss 2 is poured into the concrete ribs 3.

[0032] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
