Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides the following technical solutions:

[0028] The grooved precast slab of the composite concrete two-way stressed thermal insulation roof includes a precast slab body 1. Protective frames 4 are arranged on both the front side and the rear side of the precast slab body 1.

A fixing mechanism 7 is arranged inside the adjustment grooves 11. Four connecting mechanisms 5 are arranged on the opposite sides of the two protective frames 4. Four limiting grooves 9 are provided on the opposite sides of the two protective frames 4.

[0029] The fixing mechanism 7 includes a number of limiting pads 701, an adjustment plate 702, a moving block 703, two adjustment columns 704 and two handles 705. The top of the limiting pad 701 contacts the bottom of the precast slab body 1. The top of the adjustment plate 702 is fixedly connected to the bottom of the limiting pad 701. The top of the moving block 703 is fixedly connected to the bottom of the adjustment plate 702. The surface of the moving block 703 is slidably connected to the inside of the adjustment groove 11. The top of the adjustment column 704 extends into the adjustment plate 702 and is rotatably connected to the inside of the adjustment plate 702. The top of the handle 705 is fixedly connected to the bottom of the adjustment column 704.

[0030] In this embodiment: By moving the two protective frames 4 to the front side and the rear side of the surface of the precast slab body 1, it is convenient to protect the surface of the precast slab body 1 by the protective frames 4. By fixedly connecting the top of the handle 705 to the bottom of the adjustment column 704, it is convenient for the handle 705 to drive the adjustment plate 702 to move through the adjustment column 704, so that the adjustment plate 702 drives the limiting pad 701 to contact the bottom of the precast slab body 1. By the limitation of the adjustment plate 702 through the moving block 703 inside the adjustment groove 11, the precast slab body 1 can be driven to move to a suitable position for fixation, thus facilitating the transportation and installation of precast slab bodies 1 of different specifications and reducing damage to the surface of the precast slab body 1.

[0031] Specifically, as Figure 1 、 Figure 3 、 Figure 4 shown, eight limiting blocks 501 are arranged on the opposite sides of the two protective frames 4. The side of the limiting block 501 close to the limiting groove 9 extends into the limiting groove 9 and is in close contact with the inside of the limiting groove 9.

[0032] Specifically, as Figure 1 、 Figure 3 、 Figure 4 shown, a connecting sleeve 502 is fixedly connected between the opposite sides of the two limiting blocks 501. A connecting frame 503 is fixed inside the connecting sleeve 502.

[0033] Specifically, as Figure 2 、 Figure 4As shown, protective pads 504 are fixedly connected to both the top and bottom of the inner wall of the connecting frame 503, and the surfaces of the two protective pads 504 in contact with each other are in contact with the surface of the steel bar 14.

[0034] In this embodiment: By making the surface of the limiting block 501 closely contact the inside of the limiting groove 9, it is convenient for the limiting groove 9 to limit the connecting sleeve 502 through the limiting block 501, achieving the effect of limiting the connecting sleeve 502.

[0035] Specifically, as Figure 3 shown, moving grooves 8 are opened on both sides of the bottom of the adjusting groove 11, and the surface of the adjusting column 704 is threadedly connected to the inside of the moving groove 8.

[0036] Specifically, as Figure 1 、 Figure 3 shown, buffer pads 10 are fixedly connected to both sides of the two adjusting grooves 11 in contact with each other, and the surfaces of the two buffer pads 10 in contact with each other are in contact with the front side and the rear side of the precast slab 1 respectively.

[0037] In this embodiment: By making the surface of the adjusting column 704 threadedly connected to the inside of the moving groove 8, it is convenient for the adjusting column 704 to drive the adjusting plate 702 to move through the moving groove 8, achieving the effect of driving the adjusting plate 702 to move.

[0038] Specifically, as Figure 1 、 Figure 2 shown, two installation grooves 2 are opened on the left side of the precast slab 1, two connecting columns 3 are fixedly connected to the inside of the installation grooves 2, and two installation plates 6 are fixedly connected to the right side of the precast slab 1.

[0039] Specifically, as Figure 5 shown, three support grooves 12 are opened on both sides of the two protective frames 4 in opposite directions, and two protective cotton 13 are fixedly connected to both sides of the two protective frames 4 in opposite directions.

[0040] In this embodiment: By making the right side of the connecting column 3 fixedly connected to the right side of the inner wall of the installation groove 2, it is convenient for the precast slab 1 to be installed through the installation groove 2 and the connecting column 3, achieving the effect of facilitating the installation of the precast slab 1.

[0041] Working principle: When transporting the precast slab body 1, by moving two protective frames 4 to the front and rear sides of the surface of the precast slab body 1, the opposite sides of the two buffer pads 10 are respectively in contact with the front and rear sides of the precast slab body 1, so as to buffer and protect the front and rear sides of the precast slab body 1. The handle 705 drives the adjusting plate 702 to move inside the moving groove 8 through the adjusting column 704, so that the adjusting plate 702 drives the limiting pad 701 to contact the bottom of the precast slab body 1. By limiting the moving block 703 of the adjusting plate 702 inside the adjusting groove 11, the precast slab body 1 can be driven to move to a suitable position for fixation. Then, the connecting frame 503 drives the connecting sleeve 502 to move on the surface of the steel bar 14, so that the connecting sleeve 502 can be conveniently moved into the limiting groove 9 through the limiting block 501 for limitation. The opposite sides of the two protective pads 504 are both in contact with the surface of the steel bar 14, which reduces the damage caused by the steel bar 14 colliding with other objects when the precast slab moves, thus facilitating the transportation and installation of precast slab bodies 1 of different specifications, reducing the damage to the surface of the precast slab body 1, and solving the problems that due to the large size and heavy weight of the precast slab, large mechanical equipment is required in the transportation and installation processes, increasing the construction cost and difficulty, and the precast slab is prone to collision and damage during the transportation and installation processes.

[0042] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
