Description

Technical Field

[0001] The utility model relates to the technical field of house exterior wall insulation, in particular to a pull-out resistance detection fixture for exterior wall insulation anchor bolts. Background Art

[0002] When installing thermal insulation on the exterior walls of houses, thermal insulation anchor bolts are often used to fix the insulation boards. The pull-out resistance of the thermal insulation anchor bolts becomes a key factor restricting the service life of thermal insulation on the exterior walls of houses. When the existing thermal insulation anchor bolt pull-out resistance detection fixture clamps the anchor bolt plate and pulls it outward, the anchor bolt plate is often stressed on both sides, and the force is uneven. Therefore, it is easy to deform during the continuous pulling process. Once the anchor bolt plate is deformed, it will lead to the inability to continue to apply the outward pulling load, and the test can only be stopped and the final result can only be recorded. In this way, it is difficult to detect the limit value of the pull-out bearing capacity for the thermal insulation anchor bolts with higher pull-out resistance, resulting in inaccurate test results. Summary of the invention

[0003] The utility model aims to provide a pull-out resistance detection fixture for external wall thermal insulation anchor bolts in view of the defects of the prior art.

[0004] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0005] The external wall insulation anchor anti-pull-out force detection fixture described in the utility model comprises a fixture body of an integrated structure formed by a horizontal top plate, a horizontal bottom plate, a left vertical plate and a right vertical plate, a connecting head which is screwed and fixedly connected to an anchor puller is vertically arranged at the center of the upper surface of the horizontal top plate, a U-shaped slot for clamping the external wall insulation anchor is opened from front to back in the middle of the horizontal bottom plate, and the left and right side edges of the U-shaped slot are inclined structures inclined inward from top to bottom; a sealing plate is adapted to be inserted at the notch of the U-shaped slot, and the sealing plate has a first state of being inserted into the U-shaped slot, and a second state of being removed from the U-shaped slot, and when the sealing plate is in the first state, the sealing plate and the U-shaped slot are combined to form a square fixing opening for fixing the external wall insulation anchor.

[0006] Furthermore, the left and right side edges of the U-shaped slot are inclined structures with a slope of 45°.

[0007] The advantage of the utility model lies in that a U-shaped slot is opened on the horizontal bottom plate of the clamp body, and a sealing plate is adapted to be inserted at the notch of the U-shaped slot, thereby forming a square fixing opening for fixing the external wall insulation anchor bolt, so that the anchor plate at the top of the external wall insulation anchor bolt can be firmly clamped above the horizontal bottom plate, and the anchor rod body below the anchor plate can vertically pass through the square fixing opening, so that when the pull-out force test of the external wall insulation anchor bolt is carried out, the anchor plate can be subjected to more uniform force, and the possibility of deformation of the anchor plate during continuous pulling is reduced, which is conducive to accurately detecting the pull-out bearing capacity limit value of the external wall insulation anchor bolt and improving the accuracy of the test result.

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0013] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0014] like Figure 1-3As shown, the external wall insulation anchor anti-pull-out force detection fixture described in the utility model includes a fixture body of an integrated structure formed by a horizontal top plate 1, a horizontal bottom plate 2, a left vertical plate 3 and a right vertical plate 4; specifically, the thickness of the horizontal top plate 1, the horizontal bottom plate 2, the left vertical plate 3 and the right vertical plate 4 are consistent, all of which are 0.3 cm, and at the same time, the length of the horizontal top plate 1 and the horizontal bottom plate 2 is 7 cm, and the height of the left vertical plate 3 and the right vertical plate 4 is 2 cm, so that a cavity 5 that can accommodate the upper end anchor plate 101 of the external wall insulation anchor 100 is formed on the inner side of the horizontal top plate 1, the horizontal bottom plate 2, the left vertical plate 3 and the right vertical plate 4.

[0015] A connector 6 is vertically arranged at the center of the upper surface of the horizontal top plate 1. The connector 6 is a joint of a cylindrical structure, and an internal thread 7 that can be screwed with an anchor puller is arranged on its inner wall. A U-shaped card slot 8 for clamping the external wall insulation anchor 100 is opened from front to back in the middle of the horizontal bottom plate 2. The U-shaped card slot 8 is horizontal, and its slot width is 2 cm, which is greater than or equal to the thickest diameter of the anchor body 102 of the external wall insulation anchor 100, so as to ensure that the anchor body 102 of the external wall insulation anchor 100 can vertically pass through the U-shaped card slot 8; at the same time, the left and right side edges of the U-shaped card slot 8 are inclined structures that are inclined from top to bottom inward, and the slope feet of the two inclined structures are both 45°.

[0016] In addition, a sealing plate 9 is inserted at the notch of the U-shaped slot 8, and the left and right side edges of the sealing plate 9 are overlapping inclined surfaces with a slope foot of 135°, so as to match the left and right side edges of the U-shaped slot 8, so that the sealing plate 9 can be firmly and horizontally inserted into the notch of the U-shaped slot 8; in this way, the sealing plate 9 can have a first state of being inserted into the U-shaped slot 8, and a second state of being removed from the U-shaped slot 8, the first state is a working state for performing pull-out resistance detection of the external wall insulation anchor bolt 100, and the second state is a loading state for placing the external wall insulation anchor bolt 100, and when the sealing plate 9 is in the first state, the sealing plate 9 and the U-shaped slot 8 can just enclose a A square fixing opening 10 is used to fix the external wall insulation anchor 100. The square fixing opening 10 can make the anchor plate 101 on the top of the external wall insulation anchor 100 firmly stuck above the horizontal bottom plate 2, and the anchor rod body 102 below the anchor plate 101 can vertically pass through the square fixing opening 10, so that when the pull-out resistance of the external wall insulation anchor 100 is tested, the anchor plate 101 can be more evenly stressed through the four edges of the square fixing opening 10, reducing the possibility of deformation of the anchor plate 101 during continuous pulling, which is conducive to accurately detecting the pull-out bearing capacity limit of the external wall insulation anchor 100 and improving the accuracy of the test results.
