Description

Technical Field

[0001] The present invention relates to the field of building materials, and in particular to a limiting component for a silicon-graphene thermal insulation board and a silicon-graphene thermal insulation board comprising the limiting component. Background Art

[0002] As a new type of fireproof (fireproof grade A2) insulation material combining organic and inorganic materials, silicon graphene insulation board has the characteristics of light weight, high strength and high toughness, and has been applied to the field of exterior wall insulation. In order to further improve its strength indicators such as bending load and meet the requirements for use in non-disassembly formwork, at least one layer of steel wire mesh is often embedded in the production process before the raw material composition is pressurized and heated in the mold for finalization. However, since the raw material composition is in a gel-like state before heating and finalization, it is difficult to place the embedded steel wire mesh in the required position according to the set requirements. When more than one layer of steel wire mesh is added, the spacing between the steel wire meshes is more difficult to control. At the same time, when the silicon graphene insulation board is used as a non-disassembly insulation formwork, when the necessary inner and outer formworks are used to pull the steel bars, additional holes need to be opened on the silicon graphene insulation formwork. Since the position of the steel wire mesh cannot be controlled, holes will also be opened in the steel wire mesh, which increases the difficulty of construction and affects the construction efficiency. The above problems are issues that need to be urgently solved in the application field of silicon graphene insulation boards. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art. The present invention provides a limiting component for a silicon-graphene insulation board and a silicon-graphene insulation board containing the limiting component.

[0004] The present invention is achieved through the following technical solutions:

[0005] A limiting component for a silicon-graphene insulation board comprises a straight barrel-shaped limiting body, the outer surface of the limiting body has at least one supporting portion protruding outwardly, and the supporting portion is used to place a supporting steel wire mesh.

[0006] Furthermore, the limiting body has a through hole therein, and the through hole penetrates the limiting body along the axial direction of the limiting body, and the through hole is used for passing the tension steel bar or connecting with the blind head.

[0007] Furthermore, the inner wall surface of the through hole has a connecting portion, and the connecting portion is used to be connected to a connecting component.

[0008] Furthermore, the support portion is annular in shape, and surrounds the outer circumferential surface of the limiting body.

[0009] Furthermore, both ends of the limiting body have abutment portions respectively, and the abutment portions protrude outwardly from the outer surface of the limiting body along the axial direction of the limiting body.

[0010] Furthermore, the abutting portion is annular in shape, and surrounds the outer circumferential surface of the limiting body.

[0011] Furthermore, the limiting body, the supporting portion and the abutting portion are integrally formed, and the materials of the limiting body, the supporting portion and the abutting portion are all metal or plastic.

[0012] A silicon-graphene insulation board comprises an insulation board body, a plurality of steel wire mesh sheets and at least one limiting component for the silicon-graphene insulation board as described above, wherein the limiting body and the plurality of steel wire mesh sheets are arranged in the insulation board body, and the ends of the steel wire mesh sheets are placed on the supporting portion.

[0013] Furthermore, the thickness of the insulation board body is the same as the height of the limiting body, and the end surfaces at both ends of the limiting body are respectively located on the same plane as the top surface and the bottom surface of the insulation board body.

[0014] Furthermore, the limiting body has a through hole therein, and the through hole passes through the limiting body and the insulation board body.

[0033] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses a silicon graphene insulation board, which includes an insulation board body 1, at least one limiting component 2 for the silicon graphene insulation board, and a plurality of steel wire meshes 3. The limiting component 2 for the silicon graphene insulation board includes a straight barrel-shaped limiting body 21, and the outer surface of the limiting body 21 has at least one supporting portion 22 extending outward and protruding, and the supporting portion 22 is used to place and support the steel wire mesh 3.

[0035] The limiting body 21 and several steel mesh sheets 3 are all arranged in the insulation board body 1, and the end of the steel mesh sheet 3 is placed on the support part 22. The support part 22 can support and lean against the steel mesh sheet 3, and can effectively limit the height of the steel mesh sheet 3 in the limiting component 2, that is, the steel mesh sheet 3 can be limited in the thickness direction of the insulation board body 1 through the support part 22. At the same time, the relative position of the steel mesh sheet 3 can also be adjusted so that the position of the steel mesh sheet 3 in the insulation board body 1 meets the preset requirements. Thereby, the overall structural strength of the silicon-graphene insulation board is ensured, the stability of the silicon-graphene insulation board is greatly improved, and its service life is extended. Among them, the material of the insulation board body 1 is silicon-graphene insulation material.

[0036] The support portion 22 is annular in shape and surrounds the outer peripheral surface of the limiting body 21. The support portion 22 supports and abuts against a plurality of surrounding steel mesh sheets 3, and the support connection has high stability, thereby ensuring the limiting effect on the plurality of steel mesh sheets 3. At the same time, the structure is simple and the processing and manufacturing are convenient.

[0037] The thickness of the insulation board body 1 is the same as the height of the limiting body 21, and the end faces at both ends of the limiting body 21 are respectively located on the same plane as the top and bottom surfaces of the insulation board body 1. This makes the outer surface of the silicon-graphene insulation board smooth without any unevenness. At the same time, the limiting body 21 is arranged in the insulation board body 1 to effectively enhance the overall structural strength of the silicon-graphene insulation board, and effectively prevent the insulation board body 1 from being squeezed and damaged. In this embodiment, the height of the limiting component 2 can be 20-100mm. Of course, the height of the limiting component 2 can be adjusted accordingly according to the thickness requirements of the silicon-graphene insulation board. To ensure that the height of the limiting body 21 is the same as the thickness of the silicon-graphene insulation board.

[0038] The inner wall surface of the through hole 211 has a connecting portion, and the connecting portion is used to connect with the connecting component. The connecting portion is connected with the external connecting component, so that the limit body 21 can be connected with the external connecting component through the through hole 211, and the structural connection strength is enhanced, and the stability is high. Among them, the connecting portion can be an internal thread, and the internal thread is connected to the external connecting component through the threaded connection, and the connecting portion can be a slot or a hook. The specific structure of the connecting portion is not limited, as long as it can be connected with the external connecting component.

[0039] The material of the limiting component 2 can be metal or plastic, that is, the materials of the limiting body 21, the supporting part 22 and the abutting part 23 can all be metal or plastic. The limiting body 21, the supporting part 22 and the abutting part 23 are integrally formed. The overall structural strength of the limiting component 2 is further strengthened, and the stability of the silicon graphene insulation board is greatly improved.

[0040] The two ends of the limiting body 21 are respectively provided with abutting parts 23, and the abutting parts 23 extend outwardly from the outer surface of the limiting body 21 along the axial direction of the limiting body 21. The abutting parts 23 extend outwardly along the outer surface of the silicon-graphene insulation board, thereby increasing the supporting contact area between the limiting component 2 and the outside, further protecting the insulation board body 1, and greatly improving the stability of the silicon-graphene insulation board. Among them, the abutting part 23 is in an annular shape, and the abutting part 23 surrounds the outer peripheral surface of the limiting body 21. The abutting part 23 has high support and abutment stability, and has a simple structure and is easy to process and manufacture.

[0041] The limiting body 21 has a through hole 211 therein, and the through hole 211 penetrates the limiting body 21 along the axial direction of the limiting body 21. The through hole 211 is used to pass the tension steel bar or to connect with the blind end. The through hole 211 can be used to connect with the blind end. By connecting with the blind end through the through hole 211, the through hole 211 is blocked to avoid leakage.

[0042] The through hole 211 can also be reserved for the tension steel bar 10 to pass through. When used in construction, the tension steel bar 10 will pass through the through hole 211, so that the tension steel bar 10 will pass through the silicon graphene insulation board, the concrete layer 20 and the inner formwork 30 in sequence, and the two ends of the tension steel bar 10 are connected to the tension steel bar 10 by fasteners. The limiting component 2 can pass through the through hole 211 to allow the tension steel bar 10 to pass through and realize the reinforcement of the tension steel bar 10, thereby avoiding the expansion and explosion of the mold during the pouring of the concrete layer 20. At the same time, when painting and leveling in the later stage, the through hole 211 is filled with mortar. Among them, the outer formwork support 40 and the inner formwork support 50 are respectively arranged on the outer side of the silicon graphene insulation board and the inner side of the inner formwork 30, so as to further strengthen the structural connection strength, improve the actual application effect of the silicon graphene insulation board, and prevent safety hazards.

[0043] The through hole 211 penetrates the limiting body 21 and the insulation board body 1. The tensioning steel bar 10 penetrates the limiting body 21 and the insulation board body 1 when passing through the through hole 211, thereby penetrating the silicon graphene insulation board. Preferably, the inner diameter of the through hole 211 is 10-22 mm.

[0044] In making the silicon-graphene insulation board of this embodiment, one of the making methods includes the following steps:

[0045] Step 1: laying the raw materials of the silicon-graphene insulation board in a mold of the silicon-graphene insulation board;

[0046] Step 2: Place the limiting component 2 in the mold and insert it into the raw material of the silicon graphene insulation board so that the end of the limiting component 2 will abut against the inner wall surface of the mold;

[0047] Step three, placing a steel mesh 3 on the raw material of the silicon graphene insulation board and abutting against the support portion 22 on the outer wall of the limiting component 2;

[0048] Step 4, laying the raw materials of the silicon graphene insulation board in the mold of the silicon graphene insulation board;

[0049] Step 5, pressurizing and maintaining the pressure on the mold containing the raw materials;

[0050] Step 6: demoulding and curing after heating and shaping;

[0051] Step seven, remove the excess residual silicon graphene insulation board raw materials in the mold cavity.

[0052] Among them, the steel wire mesh 3 installed in the silicon-graphene insulation board can be a single layer or multiple layers. When installing multiple layers of steel wire mesh 3, it is only necessary to repeat the above steps three and four in a cycle.

[0053] In making the silicon-graphene insulation board of this embodiment, there is also a manufacturing method comprising the following steps:

[0054] Step 1: placing the limiting component 2 in a mold made of a silicon graphene insulation board;

[0055] Step 2: The steel wire mesh 3 to be placed is butted against the support portion 22 on the outer wall of the limiting component 2;

[0056] Step three, laying the raw materials of the silicon-graphene insulation board in the mold where the limiting component 2 and the steel wire mesh 3 are placed, and the raw materials of the silicon-graphene insulation board will reach the raw material laying amount required by the silicon-graphene insulation board manufacturing process after passing through the mesh of the steel wire mesh 3;

[0057] Step 4, pressurizing the mold and then maintaining the pressure;

[0058] Step 5: demoulding and curing after heating and shaping;

[0059] Step six: remove excess residual silicon graphene insulation board raw materials from the mold cavity.

[0060] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
