AI Technical Summary
Existing insulation boards are prone to falling off due to brittle expansion bolts in low-temperature environments, resulting in unstable fixation.
A long bolt for lightweight concrete building insulation structure is designed, including an anchor plate and a bolt column. The top of the bolt column is fixed to the middle of the bottom surface of the anchor plate, and a plug column is set at the bottom of the bolt column. The plug column is thinner to pass through the insulation board. The outside of the bolt column and the anchor plate are provided with an antifreeze layer to prevent low-temperature embrittlement.
Ensure that the bolts are not easily brittle under low temperature conditions, stably fix the insulation board, prevent it from falling off, and increase the service life of the insulation board.

Description
TECHNICAL FIELD
[0001] The utility model relates to building fixed part technical field especially relates to a long bolt for light weight concrete building heat preservation structure. BACKGROUND
[0002] At present, the heat preservation measure of building envelope structure is increasingly strengthened, among which the development of outer wall heat preservation is the most rapid, and the heat preservation effect is also better and better, and the heat preservation board is mainly used for the wall of residence, industry and public building, building roof, swimming pool, cold storage, boiler and some heat preservation engineering with special requirements for waterproof.
[0003] The fixing of the existing heat preservation board usually adopts the mode that the expansion bolt passes through the heat preservation board and is screwed into the cavity, but in the area with low temperature, the expansion bolt is prone to becoming brittle due to the influence of low temperature, thereby causing the heat preservation board to fall off. UTILITY MODEL CONTENT
[0004] In order to solve the above problems, the utility model provides the following scheme:
[0005] A long bolt for light weight concrete building heat preservation structure, including anchor disc and bolt column, the bolt column top is fixed in the anchor disc bottom surface middle part, and the bolt column bottom end is provided with the insertion column, the insertion column diameter is less than the bolt column diameter, and the insertion column lower part outer wall is tapped thread; The bolt column and anchor disc are all provided with anti-freezing layer.
[0006] Further, the length of the bolt column is at least the same as the thickness of the target heat preservation board.
[0007] Further, the length of the untapped thread part of the insertion column is 10mm.
[0008] Further, the diameter of the anchor disc is greater than 60mm.
[0009] The utility model has the advantages that the insertion column is set, the insertion column is thin and convenient to insert and pass through the heat preservation board, the bolt column is ensured to be at least the same as the thickness of the heat preservation board, and the whole bolt passes through the heat preservation board; The bolt column and anchor disc are all provided with anti-freezing layer, and the problem that the whole bolt is prone to brittle fracture due to low temperature is prevented.

[0012] In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention is further described in detail below in conjunction with the embodiments. In order to thoroughly understand the present invention, some specific details will be involved in the following description. In the absence of these specific details, the present invention can still be implemented, that is, those skilled in the art can more effectively introduce the essence of their work to other technicians in the field using these descriptions and statements here. In addition, it should be noted that it should be understood that the specific embodiments described herein are merely used to explain the present application and are not intended to limit the actual scope of protection. All raw materials used in the following examples are commercially available products.
[0013] Example 1: Figure 1 As shown, a long bolt for a lightweight concrete building insulation structure includes an anchor plate 1 and a bolt column 2. The top of the bolt column 2 is fixed to the middle of the bottom surface of the anchor plate 1. The bottom end of the bolt column 2 is provided with a plug-in column 3. The diameter of the plug-in column 3 is smaller than the diameter of the bolt column 2. The lower outer wall of the plug-in column 3 is tapped with a thread 4; the bolt column 2 and the anchor plate 1 are both provided with an antifreeze layer.
[0014] The length of the bolt 2 is at least the same as the target insulation board thickness. The length of the unthreaded portion of the plug-in column 3 is 10 mm. The diameter of the anchor plate 1 is greater than 60 mm.
[0015] The utility model inserts the plug-in column 3 and the bolt column 2 into the insulation board, and the plug-in column 3 passes through the insulation board and cooperates with the gasket 5 and the nut 6 to fix the insulation board; the utility model is provided with a plug-in column 3, the plug-in column 3 is thinner and convenient for inserting and passing through the insulation board, and the bolt column 2 is guaranteed to be at least the same thickness as the insulation board to ensure that the entire bolt passes through the insulation board; the bolt column 2 and the anchor plate 1 are both provided with an antifreeze layer to prevent the problem of the overall becoming brittle and easy to break due to low temperature.
[0016] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
