Specific implementation mode

[0038] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative work belong to the scope protected by the present utility model.

[0039] Embodiment:

[0040] The anchor bolt for the gap between the sealable tray and the rock wall provided in this embodiment is as Figures 2 - 6 shown, and it includes an anchor rod body 100, an anchor head 200, a tray 300, a pressing block 400, a sealing gasket 500 and a pressing pad part 600, wherein:

[0041] The outer wall of the bolt body 100 is provided with external threads. The bolt body 100 can be a solid steel bar or a hollow steel pipe. The anchor head 200 is installed at one end of the bolt body 100. The anchor head 200 can be a drill bit, an expansion shell anchor head or an ordinary grouting anchor head. Of course, if the bolt body 100 is a hollow steel pipe, the drill bit also needs to be provided with a slurry-retaining hole. Moreover, a slurry plug needs to be installed on the side of the tray 300 away from the pressing block 400.

[0042] The tray 300 is sleeved on the bolt body 100. The pressing block 400 is provided with a threaded through hole 450. The bolt body 100 is screwed into the threaded through hole 450. Therefore, by turning the pressing block 400, the pressing block 400 can be moved along the axial direction of the bolt body 100. The pressing block 400 is used to press the tray 300 against the rock wall 700. The sealing gasket 500 is fixedly connected to the outer edge of the tray 300. The pressing pad part 600 is installed on the pressing block 400. The pressing pad part 600 is used to apply pressure on the sealing gasket 500 to press the sealing gasket 500 against the rock wall 700.

[0043] During use, the bolt body 100 is placed in the hole opened in the engineering structure. The bolt body 100 is anchored in the hole by using the anchor head 200 or grouting. Then, the pressing block 400 is turned to press the tray 300 against the rock wall 700 by using the pressing block 400. Then, the pressing pad part 600 is controlled to press the sealing gasket 500 against the rock wall 700 by using the pressing pad part 600. Since the sealing gasket 500 is located at the outer edge of the tray 300, the sealing gasket 500 pressed against the rock wall 700 will seal the gap 800 between the tray 300 and the rock wall 700 from the outside.

[0044] Through the above structure, the bolt capable of sealing the gap between the tray and the rock wall closes the gap 800 between the tray 300 and the rock wall 700 by means of the sealing gasket 500 pressed against the rock wall 700, thereby preventing water and dust from entering the gap 800 between the tray 300 and the rock wall 700. Therefore, the bolt is less affected by rain and dust during use, has a longer service life, and higher anchoring firmness during use.

[0045] Optionally, the briquette 400 in this embodiment includes a circular plate 410, a cylinder 420, and a hexagonal prism 430. The cylinder 420 is disposed between the circular plate 410 and the hexagonal prism 430, and the circular plate 410, the cylinder 420, and the hexagonal prism 430 are coaxial. The threaded through hole 450 penetrates the circular plate 410, the cylinder 420, and the hexagonal prism 430. The outer diameter of the hexagonal prism 430 and the outer diameter of the circular plate 410 are both larger than that of the cylinder 420. The circular plate 410 is located on the side close to the tray 300, and the pressing pad portion 600 is connected to the cylinder 420. The setting of the hexagonal prism 430 facilitates applying torque to the briquette 400, and then twisting the briquette 400. The circular plate 410 is in direct contact with the tray 300, thus facilitating applying pressure to the tray 300.

[0046] Located to facilitate the tool to exert force on the hexagonal prism 430 and also to prevent the tool from reaching the cylinder 420 of the briquette 400. In this embodiment, a retaining ring 440 is provided on the outer wall of the hexagonal prism 430. The retaining ring 440 is located close to the cylinder 420. In this way, when the tool is clamped on the hexagonal prism 430, the tool contacts the retaining ring 440, and the retaining ring 440 blocks the tool from continuing to move forward and reaching the position where the cylinder 420 is located.

[0047] An alternative implementation of this embodiment is as follows: The above-mentioned pressing pad portion 600 includes a connecting rod 610, a bolt 630, and a pressing strip 640, where:

[0048] One end of the connecting rod 610 is connected to the cylinder 420. An enlarged surface block 620 is integrally formed at the other end of the connecting rod 610. A screw hole corresponding to the sealing gasket 500 is opened in the enlarged surface block 620. The screw hole penetrates the above-mentioned enlarged surface block 620, and the screw hole corresponds to the position of the above-mentioned sealing gasket 500. The bolt 630 is screwed into the screw hole. The head end of the bolt 630 is located on the side close to the sealing gasket 500. The pressing strip 640 is padded between the bolt 630 and the sealing gasket 500. The bolt 630 applies pressure on the pressing strip 640 to press the sealing gasket 500 against the rock wall 700, that is, the bolt 630 applies pressure on the pressing strip 640, thereby pressing the pressing strip 640 against the sealing gasket 500, and further pressing the sealing gasket 500 against the rock wall 700.

[0049] During specific use, when the tray 300 is pressed tightly through the briquette 400, the pressing strip 640 is immediately placed on the sealing gasket 500, and then the bolt 630 is twisted so that the bolt 630 tightly presses on the pressing strip 640. More preferably, in this embodiment, a counterbore 641 is opened in the pressing strip 640, and the above-mentioned bolt 630 is inserted into the counterbore 641. In this way, the positioning and limiting of the bolt 630 and the pressing strip 640 are further carried out, so that the pressing strip 640 is less likely to slip during use.

[0050] Optimally, as Figures 2 - 6As shown, the pressing pad portion 600 in this embodiment further includes a ring 650. One end of the connecting rod 610 is fixedly connected to the outer ring wall of the ring 650. The ring 650 is rotatably sleeved on the cylinder 420, and both ends of the ring 650 are respectively in contact with the circular plate 410 and the hexagonal prism 430. In this way, the connecting rod 610 is rotatably connected to the pressing block 400. Therefore, no matter what angle the pressing block 400 rotates to, it will not affect the use of the pressing pad portion 600. During specific use, after the pressing block 400 presses the tray 300, the connecting rod 610 and the bolt 630 are rotated to a suitable position, and then the pressing strip 640 is placed on the gasket 500. Then, the bolt 630 is rotated so that the bolt 630 is inserted into the counterbore 641 on the pressing strip 640 and the pressing strip 640 is pressed tightly.

[0051] Optionally, the outer contour shape of the tray 300 is square. Gaskets 500 are fixedly connected to the four outer side walls of the tray 300. The number of connecting rods 610 is four. Each connecting rod 610 is provided with a bolt 630, and each bolt 630 is provided with a pressing strip 640. The four pressing strips 640 respectively press the gaskets 500 on the four outer side walls of the tray 300. In this way, by using the gaskets 500 on the four outer side walls of the tray 300, the gaps 800 between various parts of the tray 300 and the rock wall 700 can be better sealed.

[0052] In this embodiment, the gasket 500 can be directly bonded to the outer side wall of the tray 300 by adhesive. As another implementation manner of this embodiment, as Figure 7 shown, a frame 310 is fixedly provided on the side edge of the tray 300 close to the pressing block 400. A connection hole is formed between the frame 310 and the tray 300. The gasket 500 is a rubber gasket, and an insertion platform 510 is provided on one side edge of the gasket 500. The insertion platform 510 is inserted into the connection hole and fixedly bonded by adhesive. In this way, the gasket 500 is more firmly connected to the tray 300.

[0053] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
