Description

Technical Field

[0001] The utility model belongs to the technical field of external wall thermal insulation, and relates to an anchor and a tensile-resistant sandwich composite thermal insulation building block. Background Art

[0002] The sandwich composite insulation block is a composite insulation block composed of three layers of inner leaf block, insulation board and outer leaf block. It has the advantages of good insulation performance, low cost and convenient construction.

[0003] At present, the connection between the outer leaf block and the inner leaf block in the sandwich composite insulation block is mainly connected by metal connectors. Although the metal connectors are easy to insert, there are also some problems. For example, the connection of the metal connectors mainly uses the friction between the surface of the metal connectors and the materials of the outer leaf block and the inner leaf block. The high-strength tensile performance of the metal connectors cannot significantly improve the connection performance between the outer leaf block and the inner leaf block. Too few metal connectors will affect the performance of the sandwich composite insulation block. Too many metal connectors will not only increase the application cost of the sandwich composite insulation block, but also reduce the insulation performance of the insulation block. Summary of the invention

[0004] The utility model proposes a tie piece and a tensile-core composite heat-insulating building block to solve the problems existing in the prior art, aiming to overcome the defect of low connection strength of the existing metal connecting pieces connecting the outer leaf blocks and the inner leaf blocks.

[0005] The utility model is achieved in this way:

[0006] A fastener, characterized in that it includes a connecting portion with an opening in a first plane and a first plug-in portion and a second plug-in portion in a second plane, the first plane is inclined relative to the second plane, the connecting portion is between the first plug-in portion and the second plug-in portion, the connecting portion has two ends at the opening position, the first plug-in portion and the second plug-in portion have a connecting end and a free end, the connecting ends of the first plug-in portion and the second plug-in portion are respectively connected to the two ends of the opening of the connecting portion, and the distance between the first plug-in portion and the second plug-in portion gradually increases from the connecting end to the free end or is arranged in parallel.

[0007] An elastic heat-insulating sleeve is provided on the outer surface of the connecting portion, and a cutout is provided on the elastic heat-insulating sleeve.

[0008] The connecting portion is in an arc shape, a square shape, a U shape or an M shape with an opening.

[0009] A tensile-resistant sandwich composite thermal insulation building block, characterized in that it includes the above-mentioned anchor piece, and also includes an inner leaf block, an outer leaf block, and an insulation board located between the outer leaf block and the inner leaf block, the connecting part is arranged in the outer leaf block or the inner leaf block, and the first plug-in part and the second plug-in part pass through the insulation board and extend to the inner leaf block or the outer leaf block.

[0010] The connecting portion is M-shaped, and the tip of the middle portion of the connecting portion is inserted into the heat insulation board.

[0011] The first plane where the connecting portion is located is in a horizontal plane, and the first plug-in portion and the second plug-in portion are inclined upward or downward along the second plane;

[0012] Alternatively, the second plane where the first plug-in portion and the second plug-in portion are located is in a horizontal plane, and the first plane where the connecting portion is located is inclined upward or downward.

[0013] The first plane where the connecting portion is located is a vertical plane and is perpendicular to the adjacent planes of the insulation board and the outer blade plate. The first plug-in portion and the second plug-in portion are inclined to the left or to the right along the second plane.

[0014] The second plane where the first plug-in portion and the second plug-in portion are located is a vertical plane and is perpendicular to the adjacent planes of the insulation board and the outer blade plate. The first plug-in portion and the second plug-in portion are inclined to the left or to the right along the second plane.

[0015] The first plug-in portion and the second plug-in portion are both provided with mounting holes, and the sandwich composite thermal insulation building block further comprises a connecting piece with two insertion parts, and the two insertion parts of the connecting piece are respectively arranged in the mounting holes of two different anchors.

[0016] The sandwich composite thermal insulation building block also includes a support member, and two ends of the support member are respectively connected to the first plug-in portion and the second plug-in portion to prevent the first plug-in portion and the second plug-in portion from approaching or moving away from each other.

[0017] The utility model has the following beneficial effects:

[0018] (1) When the sandwich composite thermal insulation block with an anchor is subjected to horizontal tension, a first blocking force is formed between the anchor and the plug-in portion because the connecting portion and the two plug-in portions of the anchor are respectively arranged on two relatively inclined different planes; a second blocking force is formed between the anchor and the plug-in portion because the two plug-in portions are arranged to extend obliquely to both sides; there is also friction between the anchor and the outer leaf block and the inner leaf block. The first blocking force, the second blocking force and the friction force jointly prevent the inner leaf block and the outer leaf block from separating from each other, thereby greatly improving the tensile strength of the sandwich composite thermal insulation block.

[0019] (2) An elastic insulation sleeve with a cutout is provided on the outer surface of the connection portion. The elastic insulation sleeve can conveniently wrap the connection portion in the middle by utilizing the elastic cutout, thereby preventing the metal tie parts from quickly transferring heat between the outer leaf block and the inner leaf block, thereby effectively improving the insulation performance of the sandwich composite insulation block.

[0020] (3) The insertion part and the mounting hole are plugged into each other to connect the connector to the first plug-in part and the second plug-in part of different anchors respectively. When the sandwich composite thermal insulation block is subjected to horizontal tension, the two anchors can work together. The connector can prevent the inner leaf block or the outer leaf block from moving away from the insulation board, so that the anchor can better hold the outer leaf block and the inner leaf block, further reducing the reliance on the friction between the anchor and the outer leaf block and the inner leaf block, and further improving the tensile strength of the sandwich composite thermal insulation block.

[0021] (4) The connecting portion of the anchor is arranged on a vertical plane, and the first plug-in portion and the second plug-in portion are tilted to the left or right along the second plane to pass through the insulation board and inserted into the inner leaf block or the outer leaf block. This can not only greatly improve the tensile strength of the sandwich composite insulation block, but also utilize the high compressive strength of the connecting portion of the metal material to improve the compressive strength and shear strength of the sandwich composite insulation block, thereby greatly improving the comprehensive mechanical properties of the block.

[0022] (5) When the connecting portion is arranged on a vertical plane or the first plug-in portion and the second plug-in portion are arranged on a vertical plane, a support member is arranged between the first plug-in portion and the second plug-in portion of the anchor member, so that the connecting portion and the support member can withstand greater pressure when the sandwich composite insulation building block is under pressure, thereby greatly improving the compressive strength of the building block.

The first plug-in portion 420 and the second plug-in portion 430 have a connecting end and a free end, the connecting ends of the first plug-in portion 420 and the second plug-in portion 430 are respectively connected to the two ends of the opening of the connecting portion 410, and the spacing between the first plug-in portion 420 and the second plug-in portion 430 gradually increases from the connecting end to the free end, and the first plug-in portion 420 and the second plug-in portion 430 form an eight-shaped shape. In other optional embodiments, the first plug-in portion 420 and the second plug-in portion 430 may also be arranged in parallel.

[0053] The anchor 400 may be made of metal material, and the outer surface of the anchor 400 has a galvanized layer or an epoxy resin layer.

The inner leaf block 200 and the outer leaf block 100 can be made of materials such as ceramsite aerated concrete blocks, lightweight aggregate concrete blocks, foamed concrete blocks or foamed cement blocks, and the inner leaf block 200 and the outer leaf block 100 are formed in the form of casting.

[0054] like Figure 5 As shown, the first plane 440 is inclined at an angle a relative to the second plane 450, and the angle a is 10°-30°, and the connecting portion 410 is an overall U-shaped with an opening. In other optional embodiments, the connecting portion 410 may be square, Ω-shaped, or arc-shaped with an opening.

[0055] In order to prevent the metal anchor 400 from quickly transferring heat between the outer blade block 100 and the inner blade block 200 , an elastic insulation sleeve 500 is provided on the outer surface of the connecting part 410 . The elastic insulation sleeve 500 is provided with a cutout 510 , and the connecting part 410 is installed through the cutout 510 .

[0056] like Figure 1 As shown, the connecting portion 410 is arranged in the outer blade block 100, the first plug-in portion 420 and the second plug-in portion 430 pass through the insulation board 300 and extend to the inner blade block 200, the first plane 440 where the connecting portion 410 is located is in a horizontal plane, and the first plug-in portion 420 and the second plug-in portion 430 are inclined upward along the second plane 450.

The combined effect of these three pulling forces can greatly improve the tensile strength of the sandwich composite insulation block.

The other structures of this embodiment are consistent with those of the fourth embodiment.

[0067] In other optional embodiments, the connecting portion 410 may also be inclined upward relative to the horizontal plane.

[0069] In the first to fifth embodiments, at least one of the first plane 440 and the second plane 450 is in a horizontal state. In this embodiment, both the first plane 440 and the second plane 450 are in a vertical state. Fig.13 As shown, Fig.13 The first plane 440 where the connecting portion 410 is located is a vertical plane and is perpendicular to the adjacent planes of the insulation board 300 and the outer blade. The first plug-in portion 420 and the second plug-in portion 430 are inclined to the left or right along the second plane 450.

[0078] The other structures of this embodiment are consistent with those of the first embodiment.

[0079] Embodiment 9

[0083] Embodiment 10

[0084] The supporting member 700 of the ninth embodiment is provided with round holes 720 at both ends. Fig. 22 As shown, end grooves 730 are provided at both ends of this embodiment, the openings of the two end grooves 730 face opposite to each other, and the first plug-in portion 420 and the second plug-in portion 430 are respectively inserted into the two end grooves 730.

[0085] Embodiment 11

[0086] The supporting member 700 of the ninth embodiment is provided with round holes 720 at both ends. Fig.23 As shown, side grooves 740 are provided at both ends of this embodiment, the openings of the two side grooves 740 face the same direction, and the first plug-in portion 420 and the second plug-in portion 430 are respectively inserted into the two side grooves 740.

[0088] like Figure 24-26 As shown, the connection portion 410 of this embodiment is M-shaped, and the middle tip 480 of the connection portion 410 is inserted into the insulation board 300 .

[0089] Since the production of high-tensile sandwich insulation composite blocks adopts the method of first inserting the anchor 400 into the insulation board 300 and then casting the outer leaf block 100 and the inner leaf block 200 on both sides of the insulation board 300, the existing anchor 400 is usually inserted at a single point or two points. When the insulation boards 300 on both sides of the insulation board 300 are cast, the anchor 400 can easily shift its position, affecting the tensile strength of the block.

[0090] This embodiment uses the first plug-in part 420, the second plug-in part 430, and the middle tip 480 of the M-shaped plug-in part to insert the insulation board 300 to form a three-point insertion and stable support fixing method, so that the anchor 400 will not be offset when the outer leaf block 100 and the inner leaf block 200 are cast on both sides of the insulation board 300, thereby ensuring the tensile strength of the block.

[0091] Among them, since the connecting part 410 and the first plug-in part 420 and the second plug-in part 430 are in different planes, the insertion points of the first plug-in part 420, the second plug-in part 430 and the middle tip 480 of the plug-in part are not in the same straight line, a stable triangular fixing structure can be formed.

[0092] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
