In this way, when pouring the concrete blocks on both sides, the problem of reducing the reserved space of the post-pouring strip will not occur due to excessive impact force during pouring. This improves the accuracy of the reserved position of the post-pouring strip and avoids affecting the subsequent construction. Attached Figure Description

Detailed Implementation

[0028] Example 1, as Figures 1-4As shown, a concrete post-pouring strip structure for building engineering includes a post-pouring strip groove 5 reserved between the ground 1 and two concrete blocks 4. Support templates 6 are provided on both sides of the inner wall of the post-pouring strip groove 5. Several adjustable support devices 2 are provided between one side of the two support templates 6. The adjustable support device 2 includes two support plates 24 and a bracket 21. A limit device 3 is provided between one side of the support plate 24 and one side of the support template 6. Threaded rods 22 are fixedly connected to both sides of the bracket 21. A sleeve 23 is sleeved on the outer surface of the threaded rod 22. One end of the sleeve 23 is fixedly connected to one side of the support plate 24. A screw hole block 25 is rotatably connected to one side of the sleeve 23. The screw hole block 25 is threadedly connected to the outer surface of the threaded rod 22. When installing the support template 6 on both sides of the post-pouring strip groove 5 to separate it from the concrete block 4, first place the two support plates 24 in the inner wall of the post-pouring strip groove 5, so that one side of them abuts against the ground 1. Then, hold the screw hole block 25 and rotate it on the threaded rod 22 on the bracket 21 to move it to one end to a certain position. This can push the sleeve 23 and the support plate 24 to move to both ends until they abut against one side of the two support templates 6, thus supporting and reinforcing them. In this way, when pouring the concrete blocks 4 on both sides, the problem of reducing the space reserved for the post-pouring strip will not occur due to excessive impact force during pouring. This improves the accuracy of the reserved position of the post-pouring strip and avoids affecting the later construction.

[0029] Reference Figure 2 As shown in the figure, this embodiment discloses that a plurality of protrusions 26 are fixedly connected to the outer surface of the screw hole block 25, and the plurality of protrusions 26 are arranged at equal intervals. By setting the protrusions 26, the contact area and contact friction of the outer surface of the screw hole block 25 can be increased, making it easier to hold and screw it manually. A bearing 27 is fixedly connected to one side of the screw hole block 25, and the inner ring of the bearing 27 is fixedly connected to the outer surface of the sleeve 23. By setting the bearing 27, the rotational wear between the screw hole block 25 and the sleeve 23 can be reduced, and the service life of both can be improved.

[0030] Reference Figure 2 As shown in the figure, this embodiment discloses that telescopic rods 28 are symmetrically fixedly connected to both sides of the bracket 21, and one end of the telescopic rod 28 is fixedly connected to one side of the support plate 24. By setting the telescopic rods 28, the movement direction of the support plate 24 can be fixed and limited, so that the support plate 24 will not shake when it moves, which facilitates the support operation. Several reinforcing rods 29 are fixedly connected to the outer surface of one end of the sleeve 23, and one end of the reinforcing rod 29 is fixedly connected to one side of the support plate 24. By setting the reinforcing rods 29, the connection area between the support plate 24 and the sleeve 23 bracket 21 can be increased, making the connection more firm and stable, and less prone to breakage and damage.

[0031] Reference Figure 3 and Figure 4As shown, this embodiment discloses a limiting device 3 comprising two limiting blocks 31. One side of the limiting block 31 is fixedly connected to one side of the support plate 24. A plurality of limiting grooves 32 are provided on one side of the support template 6, and the limiting blocks 31 are inserted into the inner wall of the limiting grooves 32. A plurality of limiting rods 33 are rotatably connected to one side of the support template 6. When the support plate 24 is placed between the two support templates 6 for support and limiting, the distance between the two support plates 24 can be adjusted first. Then, the limiting blocks 31 on one side of the support plate 24 are inserted into the limiting grooves 32, and the limiting rods 33 are rotated to a certain angle so that one side abuts against the limiting block 31. This limits the support plate 24 to one side of the support template 6, making it less prone to lateral swaying during support and reinforcement, resulting in more stable support.

[0032] Reference Figure 3 and Figure 4 As shown, this embodiment discloses that the cross-section of the limiting block 31 is T-shaped, and the cross-section of the limiting groove 32 is T-shaped. By setting both the limiting block 31 and the limiting groove 32 to T-shapes, the support plate 24 can be more firmly and stably supported when supporting the support template 6, and is less prone to shaking. An anti-slip block 34, made of rubber, is fixedly connected to one side of the limiting block 31. By setting the anti-slip block 34, the contact friction on one side of the limiting block 31 can be increased, so that when the limiting rod 33 rotates to a certain angle and one side abuts against the limiting block 31, the anti-slip block 34 will make the abutment more firm.

[0033] The working principle is as follows: When the support template 6 is installed on both sides of the post-pouring strip groove 5 to separate it from the concrete block 4, first, according to the distance between the two support templates 6, manually hold the protrusion 26 and the screw hole block 25 and rotate them on the threaded rod 22 on the bracket 21 to move them to one end to a certain position. Under the limiting action of the telescopic rod 28, the sleeve 23 and the support plate 24 can be pushed to move to both ends to a certain position. Then, the limiting block 31 on one side of the support plate 24 is inserted into the limiting groove 32. Then, the limiting rod 33 is rotated to a certain angle so that one side of it abuts against the limiting block 31, limiting the support plate 24 on one side of the support template 6 and supporting and reinforcing it. In this way, when pouring the concrete blocks 4 on both sides, the problem of reducing the space reserved for the post-pouring strip will not occur due to excessive impact force during pouring, thus improving the accuracy of the reserved position of the post-pouring strip and avoiding affecting the later construction.
