Technical Field
[0001] This utility model belongs to the field of external wall insulation construction technology, specifically, it relates to a limiting and fixing device for building insulation boards. Background Technology
[0002] Currently, with economic and social development and technological progress, there is a growing demand for external wall insulation systems that possess excellent thermal insulation, fire resistance, and waterproofing performance. The steel wire mesh combined with insulation board and cast-in-place concrete wall insulation system has successfully overcome the limitations of traditional insulation technologies and is widely used in green building and construction industrialization processes. However, existing technologies lack reliable anchoring between the steel wire mesh and the insulation board, which may lead to positional displacement of the steel wire mesh during construction. This affects the orderly bonding of the insulation core material, the steel wire mesh, and the concrete, thereby reducing the wall's thermal insulation performance and construction quality.

The first connecting plate 3, the second connecting plate 4, and the fixing plate 2 are integrally formed, and the first connecting plate 3 and the second connecting plate 4 are both perpendicular to the fixing plate 2.
[0026] The wire mesh composite insulation board cast-in-place concrete wall insulation system includes a wire mesh 10, an insulation board 9, an outer formwork 11, and an inner formwork 12. A limiting connector 1 is fixed to the insulation board 9 by plastic anchors. The wire mesh 10 is connected to the insulation board 9 via a first slot 31 and a second slot 41. The insulation board 9 is placed between the outer formwork 11 and the inner formwork 12. During concrete pouring, the concrete fills the space between the wire mesh 10, the insulation board 9, and the inner and outer formwork, forming a robust wall structure.
[0027] The wire mesh 10 is welded from transverse and longitudinal wires. The fixing plate 2, the first connecting plate 3, and the second connecting plate 4 are made of plastic. The longitudinal wires are inserted into the first slot 31, and the transverse wires are inserted into the second slot 41. The limiting connector 1 limits and fixes the wire mesh 10, so the wire mesh 10 will not shift during the pouring process, ensuring the stability of the positional relationship between the insulation board 9 and the wire mesh 10.
[0028] The plastic anchor includes an anchor rod 51 and a cap 52. The anchor rod 51 includes an expansion section and a main body section. One end of the main body section is provided with a limiting disc 53. The expansion section of the anchor rod 51 passes through the insulation board 9 and the fixing plate 2 and is connected to the cap 52. The end of the cap 52 away from the fixing plate 2 is connected to the outer template 11.

The main body section is embedded in the insulation board 9, and the length of the main body section is adapted to the thickness of the insulation board 9. The limiting disc 53 is in contact with the inner surface of the insulation board 9.
[0029] The limiting and fixing anchor 7 is made of steel bars and has a catch 71. The catch 71 is a cross-shaped structure formed by welding a first cross arm and a second cross arm. The length of the first cross arm is greater than the diameter of the limiting and fixing anchor 7, and the length of the second cross arm is adapted to the diameter of the limiting and fixing anchor 7.

The two stops are horizontally set on both sides of the locking hole, and the distance between the two stops is the same as the diameter of the limiting and fixing anchor 7. Adjust the catch 71 so that the second cross arm is horizontal and the first cross arm is vertical. Then insert the limiting and fixing anchor 7 into the locking hole, and then rotate the catch 71 so that the first cross arm is horizontal and the second cross arm is vertical. At this point, one end of the first cross arm is limited by the latch 6, and the other end is limited by the stop block. The ear 71 is fixed in the engagement gap 8.
