Description

Technical Field

[0001] This utility model relates to the field of building wall technology, and in particular to a truss and a structure that does not require disassembly and has sound insulation function. Background Technology

[0002] With the development of technology, the production of floor slabs has gradually changed from precast slabs to cast-in-place slabs. Casting is carried out by combining trusses and formwork, and the formwork is removed after molding to form the floor slab. Cast-in-place slabs ensure the uniformity with the cavity and improve the overall strength. In addition, due to the iterative upgrading of technology, cast-in-place floor slabs that do not require demolition have emerged.

[0003] When constructing a non-removable concrete slab, a base plate is used as a permanent formwork for pouring concrete, and trusses are installed on the base plate to provide rigidity, eliminating the need for traditional scaffolding support. After pouring, the floor slab is formed. The trusses are generally prefabricated and need to be spliced ​​according to the actual construction site during the use stage. In the existing technology, truss splicing is carried out by welding. However, since a large number of trusses need to be arranged during construction, welding requires a lot of time and uses a lot of welding materials. In addition, improper operation during truss welding may cause problems such as fire. Utility Model Content

[0004] The purpose of this utility model is to provide a truss and a structure that does not require disassembly and has sound insulation function, which can solve the above-mentioned technical problems.

[0005] This utility model provides a truss, comprising:

[0006] A plurality of first support ribs and a plurality of second support ribs, wherein the plurality of first support ribs and the plurality of second support ribs are staggered;

[0007] Several load-bearing structures are set on the first supporting rib;

[0008] Several first connecting devices and several second connecting devices are respectively disposed at both ends of the first supporting rib.

[0009] As a further technical solution, the load-bearing structure includes: several load-bearing units, which are arranged adjacent to each other on the first support rib.

[0010] As a further technical solution, the force-bearing unit is connected to the first supporting rib to form a triangular support structure.

[0011] As a further technical solution, the first connecting device includes:

[0012] A connecting rod is provided at one end of the first support rib; and a pusher is provided at one end of the connecting rod.

[0013] The sleeve is installed on the connecting rod.

[0014] As a further technical solution, one end of the sleeve is provided with an inner inclined surface, and in the connected state, the push head contacts the inner inclined surface.

[0015] As a further technical solution, the pusher head is a truncated cone, and the truncated cone is adapted to the inner inclined surface.

[0016] As a further technical solution, the connecting rod includes:

[0017] The fixed section is located at one end of the first support bar; one end of the connecting section is connected to the fixed section, and the other end is connected to the jacking head.

[0018] As a further technical solution, the fixed section is provided with external threads; the sleeve is provided with internal threads, and the fixed section and the sleeve are threadedly connected.

[0019] As a further technical solution, the sleeve is also provided with several openings, which divide one end of the sleeve into several limiting blocks.

[0020] This utility model also proposes a structure that does not require disassembly and has sound insulation function, including a first plate layer, a heat insulation and sound insulation layer and a second plate layer arranged in sequence, and also includes a truss; a plurality of first connecting devices and a plurality of second connecting devices are connected on adjacent trusses;

[0021] A number of first support ribs and a number of second support ribs are placed on the first slab; the surface layer is placed on the first slab, and a number of first support ribs, a number of second support ribs and a number of load-bearing structures are placed inside.

[0022] The technical solution of this utility model uses a plurality of first supporting ribs, a plurality of second supporting ribs, and a plurality of load-bearing structures to provide overall support.

Detailed Implementation

[0034] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] like Figure 1-6 As shown, the truss proposed in this utility model includes:

[0038] A plurality of first support ribs 100 and a plurality of second support ribs 200 are provided, and the plurality of first support ribs 100 and a plurality of second support ribs 200 are arranged alternately; the number of the plurality of first support ribs 100 and a plurality of second support ribs 200 is determined according to the actual situation, and is not further limited in this utility model; in addition, the plurality of first support ribs 100 and a plurality of second support ribs 200 are fixed together by welding, and the included angle between the first support ribs 100 and the second support ribs 200 after fixing is 90°;

[0039] Several load-bearing structures 300 are set on the first support rib 100; of course, depending on the manufacturing needs, several load-bearing structures 300 can also be set on the second support rib 200, subject to the actual situation; through the cooperation of several load-bearing structures 300, several first support ribs 100 and second support ribs 200, the whole structure is supported after forming; several first connecting devices 400 and several second connecting devices 500 are respectively set at both ends of the first support rib 100; during on-site construction, the number and length of the trusses are selected as needed, and the adjacent trusses are set relative to each other. The first connecting devices 400 and second connecting devices 500 on the adjacent trusses are connected, and the first connecting devices 400 and second connecting devices 500 are fixed together after the first connecting devices 400 are operated, thereby completing the connection between the adjacent trusses.

[0040] The technical solution of this utility model uses a plurality of first support ribs 100, a plurality of second support ribs 200, and a plurality of load-bearing structures 300 to provide overall support. At the construction site, after two first support ribs 100 are positioned opposite each other, the connection between adjacent first support ribs 100 is achieved by the docking of a first connecting device 400 and a second connecting device 500. Compared with the prior art, this eliminates the need for welding between the first support ribs 100; the connection between adjacent first support ribs 100 is achieved directly by docking the first connecting device 400 and the second connecting device 500. Furthermore, each first support rib 100 is provided with a plurality of first connecting devices 400 and a plurality of second connecting devices 500, which further increases the strength of the connected adjacent first support ribs 100. Simultaneously, the absence of welding material reduces costs and avoids problems such as fires.

[0041] like Figure 1 As shown, the force-bearing structure 300 includes several force-bearing units 301, which are arranged adjacently on the first support rib 100. During use, the force-bearing units 301 are subjected to force respectively, which can better withstand external forces and improve the stability of the force-bearing structure 300. The force-bearing units 301 and the first support rib 100 are connected to form a triangular support structure. In this utility model, the force-bearing units 301 can be welded to the first support rib 100 by welding metal rods, or they can be welded to the first support rib 100 by bending metal rods. The specific method depends on the actual situation, and this utility model will not be further described.

[0042] like Figure 3 and Figure 5As shown, the first connecting device 400 includes a connecting rod 401 and a sleeve 403. The connecting rod 401 is disposed at one end of the first support rib 100, and a push head 402 is provided at one end of the connecting rod 401. The sleeve 403 is disposed on the connecting rod 401. Specifically, the connecting rod 401 can be fixed to one end of the first support rib 100 by welding to ensure the connection strength between the connecting rod 401 and the first support rib 100. The sleeve 403 can rotate on the connecting rod 401, and after rotation, the sleeve 403... One end of the sleeve 403 contacts the push head 402 and deforms outward under the action of the push head 402. Since the sleeve 403 is placed inside the second connecting device 500, after the sleeve 403 is deformed, it contacts the inside of the second connecting device 500, thus completing the fixation of the sleeve 403 to the inside of the second connecting device 500. In this utility model, the second connecting device 500 is a tubular structure, and anti-slip textures can also be radially provided on the inner wall of the second connecting device 500 to improve the connection strength between the second connecting device 500 and the sleeve 403.

[0043] like Figure 2 One end of the sleeve 403 is provided with an inner inclined surface 431. In the connected state, the push head 402 contacts the inner inclined surface 431. Specifically, the push head 402 is a truncated cone, and the truncated cone is adapted to the inner inclined surface 431. When the sleeve 403 rotates on the connecting rod 401, one end of the sleeve 403 moves toward the position of the push head 402, thereby causing the inner inclined surface 431 to gradually contact the push head 402. During the contact process, one end of the sleeve 403 gradually deforms and then contacts the inner wall of the second connecting device 500 after deformation, thus completing the connection between the sleeve 403 and the second connecting device 500.

[0044] like Figure 6 As shown, the sleeve 403 is also provided with several openings 432, which divide one end of the sleeve 403 into several limiting blocks 433. In this utility model, the number of openings 432 is set as needed. At least two openings 432 are required in this utility model to divide one end of the sleeve 403 into two limiting blocks 433. This ensures that the limiting blocks 433 are subjected to a more uniform force from the pushing head 402 after deformation under the action of the pushing head 402. Preferably, in this utility model, four openings 432 are provided. An opening 432 is formed, and one end of the sleeve 403 is divided into four limiting blocks 433. When one end of the sleeve 403 gradually contacts the push head 402, the limiting blocks 433 move away from the axis and then contact the inner wall of the second connecting device 500. Since the push head 402 contacts the inner inclined surface 431, the limiting blocks 433 are in contact with the inner wall of the second connecting device 500. Under the action of friction, the limiting blocks 433 are connected to the inner surface of the second connecting device 500.

[0045] like Figure 5As shown, the connecting rod 401 includes a fixed section 411 and a connecting section 412. The fixed section 411 is located at one end of the first support rib 100. One end of the connecting section 412 is connected to the fixed section 411, and the other end is connected to the push head 402. The fixed section 411 is welded to the first support rib 100. The fixed section 411 is also used to connect to the sleeve 403, allowing the sleeve 403 to move on the fixed section 411 during rotation. The fixed section 411 has an external thread (not shown in the figure), and the sleeve 403 has an internal thread (not shown in the figure). The fixed section 411 and the sleeve 403 are threadedly connected. During use, the sleeve 403 is rotated, causing it to move on the fixed section 411 under the action of the thread. During the movement, one end of the sleeve 403 contacts the push head 402. As the position of the sleeve 403 continues to change, the push head 402 pushes the limiting block 433 to deform, completing the internal connection with the second connecting device 500.

[0046] In addition, to facilitate operation of the sleeve 403, several operating surfaces 434 are provided on the outer surface of the sleeve 403. During use, the sleeve 403 can be rotated by contacting the operating surfaces 434 with a tool (such as a wrench). Simultaneously, using a tool allows for maximum operation of the sleeve 403, ensuring the stability of the connection between the limiting block 433 and the second connecting device 500. Of course, in this invention, multiple first connecting devices 400 and second connecting devices 500 need to be used simultaneously to distribute the force on the first connecting devices 400 and second connecting devices 500, thereby improving the stability of the connection between the first connecting devices 400 and second connecting devices 500.

[0047] like Figure 7 and Figure 8 As shown, this utility model also proposes a structure that does not require disassembly and has sound insulation function, including a first plate layer 601, a thermal insulation and sound insulation layer 602 and a second plate layer 603 arranged sequentially, and also including a truss; a plurality of first connecting devices 400 and a plurality of second connecting devices 500 on adjacent trusses are connected; a plurality of first supporting ribs 100 and a plurality of second supporting ribs 200 are placed on the first plate layer 601; a surface layer 604 is placed on the first plate layer 601, and the plurality of first supporting ribs 100, a plurality of second supporting ribs 200 and a plurality of load-bearing structures 300 are placed inside; in this utility model, the first plate layer 601 and the second plate layer 603 are both lightweight concrete layers; thereby reducing the overall weight while ensuring strength; the thermal insulation and sound insulation layer 602 contains shale ceramsite, which can better absorb sound and improve the sound insulation effect; the surface layer 604 is a decorative layer, which is used for contact with the outside during subsequent use.

[0048] It should be noted that, depending on the usage, a first connecting device 400 and a second connecting device 500 can be respectively set at both ends of the second support rib 200; during the usage stage, the connection between the upper and lower ends and the left and right sides of the truss can be made more flexibly, thereby improving the installation efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
