[0045] A method for hanging and fixing a tunnel waterproof cloth 8, comprising:

[0046] Steps for installing connecting rod 2: First, connect connecting rod 2 to sleeve 1;

[0047] Pre-installation steps of the pressing block 4: insert the front end of the pressing block 4 into the through hole of the sleeve 1, such as Figure 2 As shown;

[0048] Steps for determining the installation position: put the sleeve 1 with the connecting rod 2 and the pressing block 4 installed in the designated position, close to the surface of the waterproof cloth 8; adjust the position of the connecting rod 2 so that the connecting rod 2 is pressed against the surface of the waterproof cloth 8;

[0049] Fixing steps: Hold the end of the connecting rod 2, aim the nail gun with the nail 7 installed at the nail hole 6, and drive the nail 7 in. The fixing effect is as follows: Figure 3 or Figure 4 As shown. After the nail 7 is driven in, the pressing block 4, the sleeve 1 and the connecting rod 2 are fixed, which can provide good support for the waterproof cloth 8. It should be noted that in the fixing step, the front end of the nail gun is against the pressing block 4, which will have a better effect and prevent the pressing block 4 from falling.

[0050] The above installation method can conveniently hang the waterproof cloth 8, improving the installation efficiency. The pressing block 4 and the sleeve 1 can be fixed by a nail 7, and due to the effect of the connecting rod 2, the fixing area can reach dozens of times of the nail 7, thereby greatly reducing the number and density of the nails 7 required.

[0051] Embodiment 2

[0052] A special fixing device for hanging a tunnel waterproof cloth 8, comprising:

[0053] Sleeve 1: used to be attached to the surface of the waterproof cloth 8, and a through hole is provided on the sleeve 1 for the pressing block 4 to slide, and is used in conjunction with the pressing block 4;

[0054] The pressing block 4 is used to connect with the sleeve 1. A protrusion is provided at the rear end of the pressing block 4. The protrusion cooperates with the sleeve 1 to prevent the pressing block 4 from entering the sleeve 1. The pressing block 4 is provided with a nail hole 6 for the nail 7 to pass through.

[0055] Connecting rod 2: arranged on sleeve 1, a plurality of connecting rods 2 are radially extended outward from sleeve 1, and are used to compress waterproof cloth 8 and increase the fixing area of ​​a single nail 7.

[0056] The outer wall of the sleeve 1 of the present invention is provided with a connecting rod 2, and a pressing block 4 is arranged in the sleeve 1. At the moment when the tip of the nail 7 is shot into the masonry 9, the pressing block 4 is driven to insert into the sleeve 1, and the connecting rod 2 presses the waterproof cloth 8. The fixing area can reach dozens of times that of the nail 7, thereby greatly reducing the number and density of the nails 7 required and improving the work progress of hanging the waterproof cloth 8.

[0057] Embodiment 3

[0058] A special fixing device for hanging a tunnel waterproof cloth 8, comprising:

[0059] Sleeve 1: used to be attached to the surface of the waterproof cloth 8, and a through hole is provided on the sleeve 1 for the pressing block 4 to slide, and is used in conjunction with the pressing block 4;

[0060] The pressing block 4: a matching structure is provided at its front end for connecting with the sleeve 1, and a protrusion is provided at the rear end of the pressing block 4, which matches with the sleeve 1 to prevent the pressing block 4 from entering the sleeve 1; the pressing block 4 is provided with a nail hole 6 for the nail 7 to pass through;

[0061] Connecting rod 2: arranged on sleeve 1, multiple connecting rods 2 are radially extended outward from sleeve 1, and are used to press waterproof cloth 8 and increase the fixing area of ​​single nail 7;

[0062] Matching structure: a clamping groove 41 is arranged at the front end of the pressing block 4, and a clamping ring 1.1 is arranged on the inner wall of the through hole of the sleeve 1 to match the clamping groove 41. The clamping groove 41 and the clamping ring 1.1 can also be a clamping cavity and a clamping tooth structure.

[0063] Different from the second embodiment, the present embodiment is provided with a clamping ring 1.1 and a clamping groove 41, and the fixation between the pressing block 4 and the sleeve 1 is increased on the basis of the fixation of the nail 7. After the pressing block 4 and the sleeve 1 are fixed together, the structure of the whole device is more solid and the stability is better.

[0064] Furthermore, the clamping groove 41 is an annular groove, and the clamping ring 1.1 is an annular protrusion.

[0065] Embodiment 4

[0066] For the installation of the connecting rod 2, this embodiment provides the following solutions:

[0067] The sleeve 1 is provided with mounting holes for mounting the connecting rods 2. The multiple mounting holes are evenly distributed on the sleeve 1 in a circumferential manner. The number of mounting holes is six, and the number of connecting rods 2 is the same as the number of mounting holes. The number and arrangement of the connecting rods 2 can be more diverse. The multiple connecting rods 2 are evenly distributed in a circumferential manner, and the connecting rods 2 are close to the waterproof cloth 8 while extending radially.

[0068] The connecting rod 2 is detachably connected to the sleeve 1. The connecting rod 2 is threadedly connected or snap-connected to the sleeve 1, which is convenient for storage before use and quick assembly when in use.

[0069] Embodiment 5

[0070] like Figure 5 As shown, each connecting rod 2 is provided with a cushion block 3 at one end away from the sleeve 1, so as to prevent the waterproof cloth 8 from being stabbed or scratched by the connecting rod 2. The front of the cushion block 3 is an arc surface, and the two sides of the arc surface are in contact with the waterproof cloth 8.

[0071] like Figure 6As shown, the pad 3 is made of rubber material and has a certain elasticity to prevent hard materials from cutting the waterproof cloth 8. When the connecting rod 2 applies pressure to the pad 3, the arc surface will deform, the contact area between the two sides and the waterproof cloth 8 will increase, and the waterproof cloth 8 will be hung more firmly.

[0072] An internal thread column 13, such as a copper internal thread column 13, is provided on the pad 3. The rubber of the pad 3 is wrapped on the internal thread column 13 by a hot melt process, and a connecting hole is provided on the connecting rod 2. The pad 3 is fixed to the end of the connecting rod 2 through the internal thread column 13 and the screw 12 (the screw 12 passes through the connecting hole and is connected to the internal thread column 13).

[0073] Embodiment 6

[0074] The edge of the protruding portion is provided with a convex edge 5 facing the side of the sleeve 1. The top of the outer wall of the pressing block 4 is provided with a convex edge 5, and the bottom surface of the convex edge 5 gradually approaches the waterproof cloth 8 from the inner circle to the outer circle, forming an inclined surface for pressing the connecting rod 2 toward the waterproof cloth 8. The middle part of the pressing block 4 is provided with a nail hole 6 for the nail 7 to pass through.

[0075] Furthermore, the surface where the convex edge 5 contacts the connecting rod 2 is set as a curved surface with a smooth transition, so as to avoid stress concentration and prevent the connecting rod 2 from being damaged or bent.

[0076] Embodiment 7

[0077] like Figure 7-10 In this embodiment, a pressing mechanism is also provided, and the pressing mechanism cooperates with the convex edge 5 to act on the connecting rod 2.

[0078] like Figure 8 As shown, the extrusion mechanism includes an assembly port 1.2 and an installation cavity 10 provided on the sleeve 1, and the installation cavity 10 is provided below the assembly port 1.2. The installation cavity 10 is used to install a spring 11, and the spring 11 is connected to the end of the connecting rod 2. The spring 11 enters the installation cavity 10 through the assembly port 1.2. The function of the spring 11 is to generate a resistance force when the convex edge 5 squeezes the connecting rod 2. Since the end of the connecting rod 2 can move toward the bottom of the installation cavity 10 under the action of the spring 11, the convex edge 5 can avoid damaging the connecting rod 2. At the same time, under the action of the elastic force, the end of the connecting rod 2 can be squeezed, and the end of the connecting rod 2 is fixed under the joint action of the spring 11 and the convex edge 5.

[0079] Similar to the embodiment, since the sleeve 1 and the pressing block 4 are not fixed or assembled before the nail 7 is driven in, the nail gun needs to be pressed against the pressing block 4 to prevent the pressing block 4 from falling. In order to solve the above problem, the embodiment also provides an assembly structure, which includes a positioning groove 1.3 arranged on the side wall of the assembly opening 1.2 and a positioning block 42 arranged at the bottom of the pressing block 4. A positioning bar 43 is arranged on the side wall of the positioning block 42. The positioning bar 43 is used in conjunction with the positioning groove 1.3 to fix (or preliminarily fix) the pressing block 4 and the sleeve 1.

[0080] Furthermore, there is a certain angle (obtuse angle) between the connecting end 2.1 of the connecting rod 2 and the connecting rod 2 body. This arrangement facilitates the connection end 2.1 to be pressed down and is also convenient for fixing with the top end of the spring 11.

[0081] Embodiment 8

[0082] On the basis of the seventh embodiment, the connecting end 2.1 of the connecting rod 2 and the spring 11 are first installed so that the bottom of the spring 11 contacts the bottom of the installation cavity 10. At this time, the entire spring 11 or a part of the spring 11 is in the installation cavity 10. The depth of the assembly opening 1.2 is greater than the height of the positioning block 42. At least two positioning strips 43 are arranged on the side wall of the positioning block 42, and different positioning strips 43 are arranged along the height direction of the side wall of the positioning block 42.

[0083] In the pre-assembly step of the pressing block 4, the front end of the pressing block 4 enters the through hole of the sleeve 1, so that at least one positioning strip 43 of the positioning block 42 enters the positioning groove 1.3. Fig. 9 As shown, since there are multiple positioning strips 43 at the same height, all positioning strips 43 at the same height need to enter the corresponding positioning groove 1.3. At this time, the pressing block 4 and the sleeve 1 are pre-assembled together, and since the assembly opening 1.2 is blocked by the positioning block 42, the connecting rod 2 or the spring 11 will not fall off.

[0084] Fixing step: hold the end of a connecting rod 2. Since the pressing block 4 has been installed, there is no need to worry about the pressing block 4 falling off. Align the nail 7 with the nail hole 6 and drive the nail 7 in. Under the action of the end of the nail 7, the pressing block 4 is forced to move toward the waterproof cloth 8. The positioning strip 43 that has been assembled to the positioning groove 1.3 squeezes out of the positioning groove 1.3, and the rear positioning strip 43 squeezes into the positioning groove 1.3. After fixing, due to the role of the positioning block 42, the positioning strip 43 and the positioning groove 1.3, the connection between the pressing block 4 and the sleeve 1 is tighter. The upper part of the connecting rod 2 is firmly connected under the action of the convex edge 5 and the spring 11.

[0085] The advantages of this embodiment are also:

[0086] 1. By setting the connecting rod 2, it is possible to achieve multi-point fixing with high efficiency by nailing 7 at one time.

[0087] 2. The connecting rod 2 extends radially, and the connecting rod 2 can be held during construction, and the operator's hand is away from the muzzle of the nail gun, which is more convenient and reduces safety risks.

[0088] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
