Description

Technical Field

[0001] The utility model relates to the technical field of insulation board construction, in particular to an insulation board installation anchor bolt. Background Art

[0002] Insulation board is a construction material used for building exterior walls, which is mainly used to improve the thermal performance of buildings. Conventional insulation board material is rock wool, which has good fire resistance and thermal insulation properties. When installing rock wool board, it is necessary to drill holes in the rock wool board and use insulation anchors to drive into the holes to fix the rock wool board. Conventional insulation anchors are fastened by pressing the fixed disc at the rear end on the outer surface of the rock wool board, but this disc has a large area and needs to be embedded in the rock wool board during installation, which will cause larger circular holes to be pressed out on the rock wool board. This large area of ​​circular holes will bring about a more obvious thermal bridge effect. Although the interior will be filled with rock wool later, it will still cause a higher heat exchange, thereby reducing the overall thermal insulation performance.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. The embodiments in the application and the features in the embodiments can be combined mutually without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0027] As Figures 1-8 The utility model discloses an anchor bolt, which is applied to thermal insulation board construction and installation, in particular to a thermal insulation board installation anchor bolt, which comprises an expansion pipe 1 and a fixed bolt 11 arranged in the expansion pipe 1, and the rear end of the expansion pipe 1 is provided with a fixed pipe 2 in communication with the inside of the expansion pipe 1, a plurality of groups of notches 21 are uniformly arranged on the fixed pipe 2, clamping plates 22 capable of being unfolded outward are hingedly arranged in the notches 21, and a transmission assembly is arranged in the fixed pipe 2 and mounted on the clamping plates 22.

[0028] The fixed bolt 11 is rotated and inserted into the expansion pipe 1, and at the same time, the clamping plates 22 are unfolded outward through the transmission assembly. The product changes the style of the transmission thermal insulation anchor bolt, removes the fixed disc at the rear end, adds the fixed pipe 2, and arranges the clamping plates 22 on the fixed pipe 2. When the product is punched into the rock wool board and the fixed bolt 11 is rotated to deform and tighten the expansion pipe 1, the fixed bolt 11 also synchronously drives the clamping plates 22 to unfold in the rock wool board to form a clamping, so that a large hole is avoided on the outer surface of the board body, and the overall thermal insulation effect is improved.

[0029] In an embodiment, the bottom of the clamping plate 22 is hinged with the sidewall of the notch 21, the rear end of the fixing bolt 11 is provided with a pushing head 3; the transmission assembly comprises a movable ring 31 movably limited in the fixing tube 2 and a connecting rod 32 hinged with the pushing head 3 and the clamping plate 22 respectively; when the fixing bolt 11 is rotated and extended into the expansion tube 1, the pushing head 3 at the rear end of the fixing bolt 11 will move towards the inside of the fixing tube 2, and then abut on the movable ring 31 and push it, and the movable ring 31 will push the clamping plate 22 to expand outward through the connecting rod 32, so as to expand into a larger clamping surface in the rock wool board, thereby stabilizing the board body.

[0030] In an embodiment, a plurality of limiting sliding grooves 4 are uniformly arranged on the sidewall of the fixing tube 2, the movable ring 31 is provided with a limiting clamping arm 41 which is limited to slide in the limiting sliding groove 4, and a deformable supporting rod 5 is arranged between the limiting clamping arm 41 and the sidewall of the limiting sliding groove 4; when the limiting clamping arm 41 slides downward in the limiting sliding groove 4, the supporting rod 5 is deformed, and the arrangement of the limiting clamping arm 41 stabilizes the upward and downward movement of the movable ring 31, and the supporting rod 5 is arranged to prevent the movable ring 31 from automatically sliding downward in the normal state and causing the clamping plate 22 to expand, and the supporting rod 5 can be made of plastic or nylon material, which is relatively long and thin, and only provides static support for the movable ring 31; when the pushing head 3 abuts on the movable ring 31 and moves downward, the supporting rod 5 will be compressed and deformed, bent or broken by the limiting clamping arm 41, thereby not affecting the expansion of the clamping plate 22 during use of the anchor bolt.

[0031] In an embodiment, the inner wall of the fixing tube 2 is further provided with a limiting ring 6 located below the movable ring 31 for limiting the movable ring 31, and the upper surface of the limiting ring 6 is higher than the hinged position of the connecting rod 32 and the clamping plate 22; since the force of the fixing bolt 11 extending into the expansion tube 1 is relatively large, the movable distance of the movable ring 31 relative to the fixing tube 2 is limited by the arrangement of the limiting ring 6; when the movable ring 31 moves to the position of the limiting ring 6, it will not move relative to the fixing tube 2, but will be extended into the fixing tube 2 synchronously with the expansion tube 1, thereby avoiding that the structure of the connecting rod 32 is damaged due to the movable ring 31 being abutted and moved by the pushing head 3 below the hinged position of the clamping plate 22 and the movable ring 31 during the process of the fixing bolt 11 being rotated and extended into the fixing tube 2.

[0032] In an embodiment, the outer surface of the clamping plate 22 is provided with a sawtooth surface 7 inclined on one side of the expansion tube 1; the sawtooth surface 7 is arranged to generate a larger friction force between the clamping plate 22 and the rock wool board, thereby improving the clamping stability.

[0033] In an embodiment, the fixed pipe 2 is provided with a filling pipe 8 for filling the heat preservation material on the outer surface of one end of the expansion pipe 1, and the inner surface of the filling pipe 8 is provided with an annular tooth surface 81; when the fixed bolt 11 is completely screwed into the inside of the expansion pipe 1 to make it expand tightly, the inside of the filling pipe 8 forms a small hole on the outer surface of the plate body, at this time, a small amount of rock wool or other heat preservation material can be filled in the inside to seal, and at the same time, the annular tooth surface 81 is used to make the material have a large friction with the side wall of the filling pipe 8, so that the material is not easy to fall off.

[0034] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
