Description

Inclined wire mesh frame rock wool board

technical field

The utility model relates to the field of building thermal insulation materials, in particular to a rock wool board with obliquely inserted wire steel wire grids.

Background technique

With the development of science and technology, the construction technology has also been continuously improved. The insulation technology is widely used in the construction of buildings. The insulation material used today is generally rock wool board, and the rock wool board is fixed on the building by wet paste or dry hanging technology. However, due to the relatively poor technical indicators such as the tensile and shear strength of the existing rock wool board itself, the wet-laid rock wool external thermal insulation system has instability and potential safety hazards, especially after the country puts forward new requirements for external thermal insulation and fire protection , the existing rock wool boards can no longer meet the requirements of today's construction industry for rock wool boards. Therefore, prior art should be further improved.

Utility model content

The purpose of this utility model is to provide a rock wool board with obliquely inserted steel wire grid to overcome the above-mentioned shortcomings in the current prior art.

The purpose of this utility model is to realize through the following technical solutions:

A rock wool board with obliquely inserted steel wire mesh frame, including a rock wool board, one side of the rock wool board is covered with a concave-convex low-carbon galvanized steel wire mesh; the other side of the rock wool board is obliquely inserted with several galvanized Steel wire, wherein one end of the galvanized steel wire obliquely inserted into the rock wool board is positioned and connected to the low-carbon galvanized steel wire mesh, and the other end of the galvanized steel wire extends out of the rock wool board.

Preferably, the center distance of the low-carbon galvanized steel wire mesh groove is 100mm, the height is 10mm, the mesh size is 50mm×50mm, and the diameter is Φ2.0mm; the diameter of the galvanized steel wire is Φ2.5mm, extending out of the rock The outer length of the wool board is 45mm, and the obliquely inserted galvanized steel wires per square meter of the rock wool board shall not exceed 200.

Preferably, one end of the galvanized steel wire obliquely inserted into the rock wool board is connected to the low-carbon galvanized steel wire mesh by welding.

The beneficial effects of the utility model are as follows: 1. The bonding force between the utility model and the cast-in-place reinforced concrete reaches more than 0.45Mpa, and as the base layer of the decorative brick, it fully meets the "External Wall Decorative Brick Engineering Construction and Acceptance Regulations" JGJ126-2000 And the technical standard requirements of JGJ110-97 "Inspection Standards for Bonding Strength of Decorative Bricks in Construction Engineering"; it is basically not compressed during the concrete pouring process, which ensures that the flatness of the plastered base and the effective insulation thickness are basically unchanged, and will not cause problems due to The plaster layer is too thick and the outer layer cracks; 2. The high shear strength of the utility model ensures the vertical stability of the facing brick layer; 3. The utility model is a non-combustible A-level thermal insulation material, and the thermal conductivity The plastic board is equivalent, fully meeting the country's dual requirements for external heat preservation, fire protection and heat preservation performance. the

Detailed ways

As shown in Figure 1, a kind of obliquely inserted wire steel wire grid rock wool board described in the embodiment of the present invention includes a rock wool board 1 with a board length of 2400 mm and a board width of 600 mm. One side of the rock wool board 1 is provided There is a low-carbon galvanized steel wire mesh 2, and a number of galvanized steel wires 3 are obliquely inserted on the other side of the rock wool board 1, and one end of the galvanized steel wire 3 extending out of the rock wool board 1 is welded with the low-carbon galvanized steel wire mesh 2 , the other end of the galvanized steel wire 3 stretches out of the rock wool board 1; the low-carbon galvanized steel wire mesh 2 is a convex-concave structure, and the low-carbon galvanized steel wire mesh 2 is provided with a mesh groove 4, and the center of the mesh groove 4 The distance is 100mm, the height of the mesh groove 4 is 10mm, the mesh of the low-carbon galvanized steel wire mesh 2 is 50mmx50mm, and the diameter of the mesh is 2.0mm; the diameter of the galvanized steel wire 3 is 2.5mm, and the galvanized steel wire 3 The length extending out of the rock wool board 1 is 45 mm; the number of galvanized steel wires 3 is no more than 200 per square meter.

During specific implementation, as shown in Figure 2, the rock wool board 1 with the design thickness of the obliquely inserted wire mesh rock wool board is 2400mm long and 600mm wide; 100mm, height 10mm, low-carbon galvanized steel wire mesh 2 with a mesh size of 50mm×50mm and a diameter of Φ2.0mm; galvanized steel wire 3 with a diameter of Φ2.5mm and a length extending out of the rock wool board of 45mm , and no more than 200 obliquely inserted galvanized steel wires 3 per square meter of rock wool board; obliquely inserted galvanized steel wires 3 are welded with low-carbon galvanized steel wire mesh 2, and the strength of the solder joints: tensile strength ≥ 300N. During construction, the galvanized steel wire 3 protruding 45mm from the rock wool board is bound together with the shear wall reinforcement according to the built-in method of the large formwork. After the concrete is poured, the rock wool board and the shear wall become a close indivisible whole. When performing the plastering layer 5, it is necessary to add a standard alkali-resistant glass fiber mesh to improve the crack resistance of the plastering layer.
