Embodiment 1
[0048] Attached below figure 1 - attached Figure 12 The anchor piece disclosed in this embodiment is further described;
[0049] Refer to attached Figure 1-Figure 3 As shown, the external thermal insulation anchor of the outer wall includes a sleeve 12, a disc 1 is fixed at one end of the sleeve 12, an expansion spring is fixed at the other end of the sleeve 12, and a space connecting the disc 1 and the expansion spring is provided in the middle of the sleeve 12. The cavity 2, the expansion spring includes a plurality of obliquely arranged rods 3, the end of the rods 3 is fixed with a chuck 4, and the rods 3 can move away from the axis of the sleeve 12 under the action of an external force to expand to the outside of the sleeve 12. After the expansion spring expands, the shear force with the base wall increases the pull-out force of the external thermal insulation anchor of the external wall;
[0050] In this embodiment, the expansion spring is provided with four rods 3, ...
Embodiment 2
[0060] When the above anchors are applied to concrete solid walls, the specific use is as follows Figure 6-Figure 9 As shown, the specific process is:
[0061] exist Image 6 Shown base wall body 5, special-purpose adhesive 6, adopt drilling rig to drill on the insulation layer 7. Punch using Figure 4 The drill bit shown is the same as the diameter and length of the casing 12, and the drill bit diameter is D. During the drilling process, the drill bit is kept vertical to the base wall, and the hole length is slightly longer than the length of the outer wall insulation anchor casing length. Then grind the annular groove on the hole wall of the base wall, using Figure 5 The groove-grinding drill bit shown has a diameter of D, the length of the protruding part at both ends of the connecting rod is d, and the depth of the side of the annular groove close to the insulation layer is the same as the length of the casing. Remove the drill bit and replace it with a grooved drill...
Embodiment 3
[0067] When the above-mentioned anchors are applied to the hollow block wall, the specific use is as follows: Figure 10-Figure 12 As shown, the specific process is:
[0068] exist Figure 10 The base wall body 5 shown, the special adhesive 6, and the insulation layer 7 are drilled with a drilling rig. use Figure 4 A drill bit having the same diameter and length as the casing 12 is shown, and the drill bit diameter is D. Such as Figure 10 As shown, after the drilling is completed, the hole only includes the non-enlarging head part 8 of the channel, the diameter of the channel is D, and the hole communicates with the internal cavity 11 of the hollow block wall.
[0069] Such as Figure 11 As shown, the sleeve of the anchor is put into the hole, and the rod at the lower part of the sleeve passes through the non-expanding head part of the tunnel, so that the chuck 4 enters the inner cavity 11 of the hollow block wall.
[0070] Such as Figure 12 As shown, knock the screw...
