Description

Technical Field

[0001] This utility model belongs to the technical field of precast concrete components, specifically relating to a lightweight concrete component. Background Technology

[0002] As technology continues to advance, people's standards for using their surroundings are also gradually increasing. In the construction field, in order to ensure a relatively constant temperature effect in indoor spaces, insulation systems are constructed in the early stages of building construction. A common method is to use insulated concrete bricks or components for wall construction.

[0003] Chinese Patent Publication No. CN218091253U discloses a thermal insulation concrete component, including a concrete layer, an insulation layer installed on top of the concrete, a crack-resistant surface layer provided on top of the insulation layer, and a flame-retardant and sound-insulating device provided between the insulation layer and the crack-resistant surface layer; the flame-retardant and sound-insulating device includes a lower connecting layer, a sound insulation board, and an upper connecting layer, with the lower connecting layer installed on the side of the insulation layer near the crack-resistant surface layer, the upper connecting layer installed on the side of the crack-resistant surface layer near the insulation layer, and a sound insulation board provided between the lower connecting layer and the upper connecting layer.

[0004] Existing thermal insulation concrete components require the addition of many functional layers or structures to improve their thermal insulation, flame retardancy, and sound insulation properties, resulting in heavy concrete components that are unsuitable for buildings with lightweight requirements.

[0005] Therefore, how to reduce the weight of concrete components without compromising their thermal insulation, flame retardancy, sound insulation, and protective effects is a problem that needs to be solved in this field. Utility Model Content

[0006] In view of the above-mentioned technical problems of existing concrete components, the purpose of this utility model is to provide a lightweight concrete component. By setting an insulation layer, a flame-retardant layer, a sound insulation layer on the outside of the concrete block and setting a cavity inside the protective layer, the structural weight can be reduced without reducing the insulation, flame-retardant and protective effects of the concrete component.

[0007] To achieve the above objectives, the present invention provides a lightweight concrete component comprising a concrete block, wherein a heat insulation layer, a flame retardant layer, a sound insulation layer, and a protective layer are sequentially provided on both ends of the concrete block, and a cavity is provided inside the concrete block, and the protective layer is connected to the concrete block by an elastic element.

[0008] Furthermore, each end of the concrete block is provided with a placement groove, and the heat insulation layer, flame retardant layer, and sound insulation layer are sequentially placed in the placement groove, with the outer surface of the sound insulation layer flush with the surface of the concrete block.

[0009] Furthermore, the sound insulation layer has several cavities inside, each cavity being filled with sound insulation material or sound absorption material.

[0010] Furthermore, the protective layer is composed of a protective plate and an elastic element. The elastic element is connected between the protective plate and the concrete block. The elastic element is a rubber body, which is bonded to both the protective plate and the concrete block.

[0011] Furthermore, the concrete block is composed of two parts with identical structures and symmetrical arrangement. One end face of each part is provided with a mounting groove for embedding the insulation layer, flame retardant layer, and sound insulation layer.

[0012] The other end face is provided with a groove, and the split body is provided with a corresponding connecting hole. The two split bodies are symmetrically arranged and connected, so that the grooves on the two split bodies are combined to form a cavity for the insulation vacuum body to be placed. Fasteners are used to pass through the connecting holes on the two split bodies to make the two split bodies detachably connected.

[0013] Furthermore, the split end face is also provided with several grooves, so that the grooves on the two splits can be combined to form several cavities.

[0014] Furthermore, the elastic member is provided with a first connector and a second connector at both ends. The second connector is fixedly connected to the protective plate. The second connector has an opening, which corresponds to the connecting hole on the split body. In this way, the fastener passes through the opening on the second connector and the connecting hole on the two split bodies in sequence to fix the second connector and the two split bodies together. The second connector is squeezed between the fastener and the split bodies.

[0015] Furthermore, the surface of the sound insulation layer is provided with a number of micro-holes corresponding to the cavity, the micro-holes are connected to the cavity, and the cavity is connected to the outside through the holes.

[0016] The lightweight concrete component provided by this utility model can greatly improve the protective effect of the protective layer by utilizing the elastic properties of the elastic element. By setting a heat insulation layer, a flame retardant layer, and a sound insulation layer on the outside of the concrete block, and setting a cavity inside the protective layer, the structural weight can be reduced without reducing the heat insulation, flame retardant and protective effect of the concrete component.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0027] Example 1:

[0028] See Figure 1 The diagram shown is a structural schematic of the lightweight concrete component provided by this utility model.

[0029] As shown in the figure, the lightweight concrete component provided by this utility model includes a concrete block 100 as one component.

[0030] Among them, the two ends of the concrete block 100 are respectively provided with a heat insulation layer 200, a flame retardant layer 300, a sound insulation layer 400, and a protective layer 500.

[0031] The concrete block 100 has a cavity 110 inside, and the protective layer 500 is connected to the concrete block 100 by an elastic element 520.

[0032] The concrete components provided in this solution are treated with a flame-retardant layer 300 and a sound-insulating layer 400 to reduce noise and flames from the outside world.

[0033] Furthermore, the protective layer 500 can buffer the impact and collision of the outside world relative to the concrete block 100. In this solution, the protective layer 500 and the concrete block 100 are further connected by an elastic element 520. The elastic properties of the elastic element 520 can greatly improve the protective effect of the protective layer 500.

[0034] By providing a cavity 110 inside the concrete block 100, the structural weight of the concrete block 100 can be greatly reduced.

[0035] Furthermore, the cavity 110 can be composed of a single cavity or a number of cavities.

[0036] Furthermore, in order to improve the reliability of the connection between the concrete block 100 and the insulation layer 200, the flame retardant layer 300, and the sound insulation layer 400, the concrete block 100 is provided with a placement groove 130 at both ends, and the insulation layer 200, the flame retardant layer 300, and the sound insulation layer 400 are placed in the placement groove 130 in sequence, with the outer surface of the sound insulation layer 400 flush with the surface of the concrete block 100.

[0037] With the installation groove 130, the insulation layer 200, flame retardant layer 300, and sound insulation layer 400 can be embedded therein, and the installation groove 130 can restrict the horizontal movement of each layer.

[0038] This solution does not limit the shape of the concrete block 100 and its internal cavity 110, which can be determined according to actual needs. For example, the concrete block 100 is preferably rectangular, and the cavity 110 is preferably elliptical or rectangular.

[0039] The insulation layer 200 can be an aerogel layer, a rock wool board layer, or a ceramic board layer.

[0040] The flame retardant layer 300 can be a nano-alumina layer or a nano-silicate layer.

[0041] The sound insulation layer 400 has several cavities 410 inside, each cavity 410 is filled with sound insulation material or sound absorption material, and external noise can be absorbed or blocked by the noise reduction material or sound insulation material in the cavity 410.

[0042] The aforementioned sound-absorbing material is preferably a granular or foamed material to form a porous structure, including one or a mixture of glass wool, polyester fiber sound insulation cotton, centrifugal glass wool, rock wool, mineral wool, and plant fibers.

[0043] The sound insulation material mentioned above is preferably one or a combination of steel plate, lead plate, and brick wall.

[0044] The protective layer 500 is composed of a protective plate 510 and an elastic element 520. The elastic element 520 is connected between the protective plate 510 and the concrete block 100. The elastic element 520 is a rubber body, which is bonded to the protective plate 510 and the concrete block 100 respectively.

[0045] When the protective layer 500 is impacted by external forces, the elastic element 520 can undergo elastic deformation to buffer the impact.

[0046] Example 2:

[0047] This embodiment describes the structure of the concrete block 100 based on embodiment 1. The rest of the structure is the same, so it will not be described in detail here.

[0048] In Example 1, the concrete block 100 is an integral structure, while in this example, the concrete block 100 is a split structure. When the concrete block 100 is split, the two are connected in a detachable manner, and it is constructed by connecting two modular splits. When different sizes are required, the modular splits can be disassembled and replaced to improve the overall applicability of the concrete component.

[0049] like Figure 2 The concrete block 100 is composed of two parts 101. The two parts 101 have the same structure and are arranged symmetrically. One end face of the part 101 is provided with a mounting groove 130, in which the insulation layer 200, the flame retardant layer 300, and the sound insulation layer 400 can be embedded.

[0050] The other end face is provided with a groove 111, and the split body 101 is provided with a corresponding connecting hole 112. The two split bodies 101 are symmetrically arranged and connected, so that the grooves 111 on the two split bodies 101 are merged to form a cavity 110. Fasteners 600 are used to pass through the connecting holes 112 on the two split bodies 101 so that the two split bodies 101 can be detachably connected.

[0051] By removing the fastener 600, the two parts 101 can be separated to allow for flexible adjustments to the parts 101.

[0052] Furthermore, such as Figure 3 The aforementioned split end face can also be provided with several grooves 111, so that the several grooves 111 on the two splits 101 can be combined to form several cavities 110.

[0053] Example 3:

[0054] This embodiment describes the structure of the protective layer 500 based on embodiment 2. The rest of the structure is the same, so it will not be described in detail here.

[0055] In Example 2, the protective layer 500 and the concrete block 100 are fixedly connected, while in this example, the protective layer 500 and the concrete block 100 are detachably connected so that the protective layer 500 can be disassembled.

[0056] like Figure 3The elastic member 520 has a first connector 530 and a second connector 540 at both ends. The second connector 530 is fixedly connected to the protective plate 510. The second connector 540 has an opening, which corresponds to the connection hole 112 on the split body 101. In this way, the fastener 600 passes through the opening on the second connector 540 and the connection hole 112 on the two split bodies 101 in sequence to fix the second connector 540 and the two split bodies 101 together. The second connector 540 is squeezed between the fastener 600 and the split body 101. If disassembly is required, only the fastener 600 needs to be removed.

[0057] Example 4:

[0058] This embodiment describes the structure of the sound insulation layer 400 based on embodiment 1. The rest of the structure is the same, so it will not be described in detail here.

[0059] To further improve the noise reduction effect of the 400 sound insulation layer, such as Figure 4 In this embodiment, the surface of the sound insulation layer 400 is provided with a plurality of micro-holes 420 corresponding to the cavity 410. The micro-holes 420 are connected to the cavity 410, and the cavity 410 is connected to the outside through the through holes 410 to enhance sound transparency so that it can be fully absorbed by the sound-absorbing material inside the cavity 410.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
