Description

Technical Field

[0001] The present invention relates to the field of construction engineering technology, and in particular to a tie assembly for a composite thermal insulation wall structure. Background Art

[0002] With the increasing demands for energy conservation and fire protection in buildings, external insulation can no longer fully meet industry needs. Currently, the integration of insulation and structure in cast-in-place concrete composite shear walls with built-in insulation is becoming increasingly popular. This involves placing a grid panel composed of insulation boards and steel mesh in the center of the wall. During construction, concrete is poured simultaneously on both sides to form a composite insulation structure system.

[0003] After searching, the public (announcement) number CN213296749U discloses a point-connected built-in thermal insulation composite wall tie assembly, including a pull rod and a positioner. The pull rod is set through the insulation board, and the two ends of the pull rod are respectively set as conical heads, and the conical heads are connected to the frustum. Positioners are installed at both ends of the pull rod. The positioner includes a base, a support part, and a positioning column. The base is a circular ring structure, and the support part is fixed on the upper part of the base... This application has the advantages of easy use, simple operation, labor saving, and reduced labor intensity of workers, and has a good effect on fixing the insulation board. However, the length of the pull rod of this application cannot be adjusted, so it is not suitable for use with insulation boards of different sizes, which reduces the applicability of the device.

[0004] In summary, how to make the tie rods suitable for insulation boards of different sizes and improve their applicability is a technical problem that needs to be solved urgently. To this end, we propose a tie assembly for composite insulation wall structures. Utility Model Content

The plate is set, the inner wall of the steel bar inlet groove is provided with a steel bar groove, the interior of the fixed tube is slidably inserted with a sliding rod, the right end of the sliding rod passes through the middle of the limit plate and extends to its outside, the right end of the sliding rod is provided with a limiting assembly, and a circular plate is provided inside the fixed sleeve near the left side of the insulation board, the left end of the fixed tube passes through the second through hole and is fixedly connected to the circular plate, and a third through hole is provided on the circular plate, the third through hole is provided for the sliding rod to pass through, thereby increasing the adjustment range when adjusting the total length of the sliding rod and the fixed tube. A plurality of limiting grooves are provided on the outside of the sliding rod, and a fixing bolt is threadedly inserted on the fixing tube, and the fixing bolt and the limiting groove are used in conjunction with each other.

[0006] According to the technical solution provided in the embodiment of the present application, the limit assembly includes a groove symmetrically opened on the outside of the sliding rod, the internal sliding connection of the groove is connected to a limit block, a spring is fixedly connected between the limit block and the inner bottom wall of the groove, and the limit block is arranged in an inclined surface on the side away from the sliding rod.

[0007] According to the technical solution provided in the embodiment of the present application, the plurality of limit grooves are arranged in sequence from left to right, and the distances between two adjacent limit grooves are equal.

[0008] According to the technical solution provided in the embodiment of the present application, a threaded hole is provided on the fixing tube, and the fixing bolt is threadedly inserted into the threaded hole.

[0009] According to the technical solution provided in the embodiment of the present application, a sliding groove is provided on the sliding rod, and a limiting strip adapted to the sliding groove is fixedly connected to the inner wall of the fixed tube.

[0010] According to the technical solution provided in the embodiment of the present application, the plurality of connecting rods are arranged in a ring array, and the distance between two adjacent connecting rods is equal.

[0011] According to the technical solution provided in the embodiment of the present application, sliding grooves are symmetrically provided on the inner wall of the groove, and a matching sliding block is slidably connected inside the sliding groove, and the sliding block and the limit block are integrally formed.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Release the fixation of the slide rod and drive the slide rod inside the fixed tube to move, so that the total length of the fixed tube and the slide rod can be adjusted, so that it is suitable for use with insulation boards of different sizes, which improves the applicability of the device. After the adjustment is completed, screw the fixing bolt into the corresponding limit groove to complete the limit fixation of the slide rod.

[0014] 2. When the limit plate and the fixed sleeve are arranged on the outside of the sliding rod, it is only necessary to drive the fixed sleeve on the right side of the insulation board to move to the left. Since the limit block is arranged at an inclined surface on the side away from the sliding rod, the fixed sleeve on the right side of the insulation board can squeeze the limit block when it moves to the left. The limit block is squeezed and moves and squeezes the spring. The spring is squeezed and contracts until the first through hole on the fixed sleeve on the right side of the insulation board moves to the left side of the limit block. At this time, the thrust generated by the spring reset causes the limit block to return to its original position, thereby forming a limiting effect on the fixed sleeve on the right side of the insulation board. In summary, the operation is simple, time-saving and labor-saving, and effectively improves the work efficiency of workers. BRIEF DESCRIPTION OF THE DRAWINGS

The second through hole 14 is for the fixing pipe 11 to pass through when installing the fixing pipe 11. The setting of the first through hole 23 facilitates the installation of the limit plate 2. A steel bar inlet groove 5 is provided on the fixing sleeve 6. The notch of the steel bar inlet groove 5 is set back to the insulation board 1. The inner wall of the steel bar inlet groove 5 is provided with a steel bar groove 4. The steel bar inlet groove 5 and the steel bar groove 4 are both prior art. Their functions refer to a point-connected built-in insulation composite wall tie assembly with a publication (announcement) number of CN213296749U, which will not be described in detail herein.

[0025] The interior of the fixed tube 11 is slidably plugged with a slide rod 7, the right end of the slide rod 7 passes through the middle of the limit plate 2 and extends to its outside, the right end of the slide rod 7 is provided with a limit assembly, and a circular plate 19 is provided inside the fixed sleeve 6 near the left side of the insulation board 1, the left end of the fixed tube 11 passes through the second through hole 14 and is fixedly connected to the circular plate 19, a third through hole 18 is provided on the circular plate 19, and the third through hole 18 enables the slide rod 7 to pass through when it moves inside the fixed tube 11, and a plurality of limit grooves 15 are provided on the outside of the slide rod 7, and the plurality of limit grooves 15 are arranged in sequence from left to right, and two adjacent limit grooves 1 are arranged in sequence. 5, the spacing between them is equal, a fixing bolt 16 is threadedly inserted on the fixing tube 11, a threaded hole 17 is opened on the fixing tube 11, the fixing bolt 16 is threadedly inserted into the inside of the threaded hole 17, the fixing bolt 16 and the limiting groove 15 are used in conjunction with each other to release the fixation of the slide bar 7, and drive the slide bar 7 inside the fixing tube 11 to move, so that the total length of the fixing tube 11 and the slide bar 7 can be adjusted, so that it is suitable for use with insulation boards 1 of different sizes, thereby improving the applicability of the device. After the adjustment is completed, the fixing bolt 16 is screwed and inserted into the corresponding limiting groove 15 to complete the limit fixation of the slide bar 7.

[0026] See also Figure 2 The limit assembly includes a groove 20 symmetrically opened on the outside of the slide rod 7, the inner sliding connection of the groove 20 is a limit block 8, a spring 21 is fixedly connected between the limit block 8 and the inner bottom wall of the groove 20, the limit block 8 is arranged in an inclined surface away from the slide rod 7, and the inner wall of the groove 20 is symmetrically provided with a sliding groove 12, and the inner sliding connection of the sliding groove 12 is adapted to the sliding block 22.

The limiting block 8 moves to squeeze the spring 21, and the spring 21 is squeezed and contracts until the first through hole 23 on the fixing sleeve 6 on the right side of the insulation board 1 moves to the limiting When it reaches the left side of the positioning block 8, it stops moving. At this time, the spring 21 resets and the limit block 8 returns to its original position, thereby forming a limiting effect on the fixing sleeve 6 on the right side of the insulation board 1, and then drives the sliding rod 7 to move to the left, and makes the limit plate 2 fit on the right side of the insulation board 1 (the connecting rod 3 is used to fix the fixing sleeve 6 and the limiting ring 9 on the left side of the insulation board 1 and the fixing sleeve 6 and the limiting plate 2 on the right side of the insulation board 1, and the connecting rod 3 is installed before the insulation board 1 is fixed.), then screw the fixing bolt 16, and insert the lower end thread of the fixing bolt 16 into the inside of the corresponding limiting groove 15, and then fix the two fixing sleeves 6 on the wire mesh through the cooperation of the steel bar inlet groove 5 and the steel bar groove 4, thereby completing the fixation of the insulation board 1.
