Description

Technical Field

[0001] The utility model relates to a fixing device for waterproof coiled material, in particular to a core rod of multi-layered waterproof coiled material. Background Art

[0002] Waterproof membrane is a basic material used for paving in buildings for the purpose of achieving waterproofing. Waterproof membrane can be made of a variety of materials. The main laying and fixing methods of waterproof membrane include adhesive fixing system, mechanical fixing system, etc. The adhesive fixing system fixes the waterproof membrane through coatings, and the mechanical fixing system fixes the waterproof membrane through external fixings and other structures and materials. The waterproof membrane used for mechanical fixing systems and other fixing methods is a multi-layer structure. The multi-layer materials mainly realize the functions of water isolation, heat preservation, and air isolation. When paving, the multi-layer materials need to be paved in sequence, which requires a long working time and needs to be pre-fixed, which is not conducive to rapid construction, and therefore needs to be improved. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and provide a multi-layer waterproof coiled material core rod.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: the core rod includes a winding drum and a material head clamp, the winding drum is a cylindrical structure, the outer ring surface of which is used to wind the coiled material, a material embedding groove is provided on the winding drum, and a material head clamp is provided corresponding to the material embedding groove, one end of the material head clamp is rotatably connected to the winding drum, and a material clamping gap is formed after the material head clamp and the material embedding groove are clamped together, and the end of the coiled material is clamped and fixed in the material clamping gap, and the outer surface of the material head clamp is arc-shaped and is arranged in a contour with the outer arc surface of the winding drum. The winding drum is the main structure for winding waterproofing coiled material, and the material head clamp is provided on its surface, and the material head clamp can clamp the edge of the coiled material and wind it in the forward direction. In the state of winding and wrapping tightly, the material head clamp will not loosen, and can maintain the flatness of the coiled material during paving, and maintain a certain tension, thereby improving the paving efficiency.

[0005] Furthermore, a rotating shaft rod is coaxially arranged in the winding drum, and both ends of the rotating shaft rod are arranged beyond the end surface of the winding drum, and the winding drum and the rotating shaft rod are rigidly connected by a connecting body. The rotating shaft rod protrudes outward to form an axial end structure, which can be used in conjunction with the winding frame to improve construction efficiency.

[0006] Furthermore, the surfaces of the material head clamp and the material insertion groove are both provided with clamping teeth, and the tooth shapes of the clamping teeth are arranged opposite to each other and pressed into the material of the coil. The clamping teeth can increase the clamping reliability and have a better clamping effect for coils with smooth surfaces such as thermal insulation materials.

[0007] Furthermore, the surface of the coil drum is attached with an anti-skid adhesive tape, which is arranged near the edge of the embedding groove and is extended along the arc surface. The anti-skid adhesive tape increases the surface friction of the coil drum, enhances the fitting effect between the coil surface and the coil drum surface, and has better flatness during winding and unwinding.

[0008] Furthermore, the material head clamp and the material coil are staggered with hinged ears, and the adjacent hinged ears are respectively formed on the material head clamp and the material coil, and all the hinged ears are coaxially connected through a through pin, and the material head clamp is rotated around the through pin. The connection distance of the hinged ears is long, and the coaxial effect of the rotation of the material clamp is good, which can be used for coils with longer widths and better paving construction efficiency.

[0009] Furthermore, there are more than two material head clamps arranged circumferentially on the material coil, and the material slots are arranged relatively to the number of material head clamps. With multiple material clamps, multiple layers or multiple materials of coils can be wound on the same roll, so that one-time paving of multiple materials can be achieved, and the rapid fixing of mechanical fixing parts can be combined to achieve a better rapid paving purpose.

[0010] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the roll-state fixing structure of the waterproofing membrane, which can fix the winding end of the membrane, and can achieve smooth winding under the condition of a fixed foundation, so as to maintain the overall surface quality of the membrane and achieve better paving construction quality. In addition, multiple layers can be fixed and wound on the same roll to achieve one-time paving of multiple materials, which greatly reduces the construction time and is suitable for various emergency waterproofing facilities.
