However, when the roofs are laid with corrugated steel sheets, they need to be waterproofed and waterproof rolls are laid on the corrugated steel sheets. The surface of the corrugated steel sheets is uneven, which makes it difficult to lay the waterproof rolls. Therefore, a layer of steel wire mesh can be laid on the surface of the corrugated steel sheets first, and the surface of the corrugated steel sheets can be leveled. Finally, the waterproof rolls are laid on the steel wire mesh. However, the contact area between the steel wire mesh and the waterproof rolls is small, and the waterproof rolls are not easy to fix on the steel wire mesh. Therefore, a device is needed to connect and fix the steel wire mesh and the waterproof rolls so that the waterproof rolls can be more firmly connected to the steel wire mesh to achieve a good waterproof effect.

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1 As shown, a nail-free gasket includes a clamping block 1, and an insertion portion 2 and a locking portion 3 are provided on the clamping block 1. The insertion portion 2 and the locking portion 3 are connected. The open end of the insertion portion 2 is located at one end of the clamping block 1. Before laying the waterproof membrane, a steel mesh is first welded and fixed on the corrugated steel plate. The steel mesh is formed by a plurality of steel wires crossing horizontally and vertically. Then the clamping block 1 is connected to the steel mesh. A plurality of clamping blocks 1 are evenly distributed on the steel mesh. During the fixed connection process between the two In the process, first insert the clamping block 1 into the steel mesh so that the steel wire is inserted into the extension part 2, then rotate the clamping block 1 to make the steel wire enter the locking part 3, and fix the clamping block 1 to the steel mesh. Finally, the waterproof membrane and the clamping block 1 are fixed by hot-melt welding to complete the laying of the waterproof membrane. Since the steel mesh can be shaped into a plane after being laid on the corrugated steel plate, and the fixed connection between the nail-free gasket and the steel mesh is convenient and quick, it is more convenient to lay the waterproof membrane and avoid water leakage in the later stage.

[0025] Furthermore, a pad 4 is provided at one end of the clamping block 1, and the clamping block 1 and the pad 4 are both circular structures. The size of the pad 4 is larger than that of the clamping block 1 to increase the contact area between the nail-free gasket and the waterproof membrane. The clamping block 1 and the pad 4 are made of polymer plastic material, and the clamping block 1 and the pad 4 are integrally molded. The clamping block 1 is fixedly connected to the steel mesh, and the extending portion 2 and the locking portion 3 are both arranged on the clamping block 1.

[0026] Furthermore, the side of the pad 4 away from the clamping block 1 is flat, and the side of the pad 4 away from the clamping block 1 is provided with anti-slip grooves to prevent the waterproof roll from sliding. The waterproof roll is laid and welded to the side of the pad 4 away from the clamping block 1.

[0027] Furthermore, if Figure 2 As shown, the extension portion 2 includes a first connecting groove 5 and a second connecting groove 6, the first connecting groove 5 is vertically arranged on the clamping block 1, and the open end of the first connecting groove 6 is located at the end of the clamping block 1 away from the pad 4, the first connecting groove 5 is a "cross" structure, which can divide the clamping block 1 into four fixed blocks evenly, and the steel wire mesh is a steel wire cross-arranged horizontally and vertically, so the first connecting groove 5 can be inserted at the intersection of the steel wires, the second connecting groove 6 is horizontally arranged on the clamping block 1, the second connecting groove 6 is connected to the first connecting groove 5, and there are four second connecting grooves 6, which are respectively located on the four fixed blocks. After the steel wire is inserted into the first connecting groove 5, since the first connecting groove 5 and the second connecting groove 6 are connected, and the second connecting groove 6 is horizontally arranged, the steel wire can be clamped into the second connecting groove 6 by rotation, and the fixed gasket will not fall off the steel wire mesh at this time. Finally, the waterproof membrane can be laid on the pad 4.

[0028] In another embodiment, if Figure 1 and Figure 3 As shown, the clamping block 1 is also provided with a locking portion 3, and the locking portion 3 includes a third connecting groove 7 and a fixing groove 8. The third connecting groove 7 is vertically arranged on the clamping block 1, and the third connecting groove 7 is connected to the second connecting groove 6. The fixing groove 8 is horizontally arranged on the clamping block 1, and the fixing groove 8 is connected to the third connecting groove 7. The fixing groove 8 and the second connecting groove 6 are arranged in parallel. The size of the fixing groove 8 is the same as the diameter of the steel wire, and the fixing groove 8 and the first connecting groove 5 are arranged at a certain angle, which is 30-45 degrees in this embodiment. There are four fixing grooves 8 and three connecting grooves 7, respectively located on four fixed blocks. After the steel wire enters the second connecting groove 6, since the second connecting groove 6 and the third connecting groove 7 are connected, and the third connecting groove 7 and the fixing groove 8 are connected, the steel wire can be entered into the third connecting groove 7 by pulling the nail-free gasket, and finally the steel wire is clamped into the fixing groove 8 by rotating the nail-free gasket, so that the steel wire mesh is fixedly connected to the nail-free gasket, which is convenient for the subsequent laying of the waterproof membrane.

[0029] In another embodiment, if Figure 4As shown, the first connecting groove 5 is an "I"-shaped structure, which can divide the clamping block 1 into two fixed blocks evenly. There are two second connecting grooves 6, and the two second connecting grooves 6 are located on the same fixed block. The second connecting groove 6 is connected to the first connecting groove 5. During the connection between the clamping block 1 and the steel mesh, the steel wire on the steel mesh is inserted into the first connecting groove 5, and then the steel wire is moved to the second connecting groove 6. The nail-free gasket can be hung on the steel mesh without falling off and separating. Finally, the waterproof membrane is laid on the pad 4 for welding and fixing.
