Detailed ways

The specific embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the utility model. Although the invention has been described in conjunction with preferred specific embodiments thereof, these embodiments are illustrative only and do not limit the scope of the invention.

Referring to FIG. 1 , a fastening device for waterproofing membranes on soft ground roofs includes bolts 1 , blooming tubes 2 , gaskets 3 and nuts 4 . The bolt 1 is a galvanized bolt of Φ4 mm, and the head of the bolt 1 is a round head, oblate head or countersunk head, so as to prevent the head of the bolt 1 from being in contact with the waterproof membrane for a long time and causing damage to the waterproof membrane . The flowering tube 2 is made of Φ8*80 mm galvanized steel pipe, the flowering tube 2 is set on the shaft of the bolt 1, and the tube wall at the end of the flowering tube 2 away from the head of the bolt 1 is evenly distributed along the circumferential direction. A plurality of splitting grooves 201, the extension direction of the splitting grooves 201 is parallel to the axis of the flowering tube 2 and one end of the splitting grooves 201 leads to the end face of the flowering tube 2 away from the head of the bolt 1, the length of the splitting grooves 201 is 20 mm , referring to FIG. 2 and FIG. 3 , there are four split grooves 201 uniformly distributed along the circumferential direction on the tube wall at the end of the flowering tube 2 away from the head of the bolt 1 . The diameter of the gasket 3 is 30 mm, and the thickness is 2 mm. It is made of circular galvanized steel plate. The gasket 3 is set on the stem of the bolt 1, and is arranged on the head of the bolt 1 and the close bolt of the flowering tube 2. 1 Between the other ends of the head, the gasket 3 is mainly to increase the stress area of the waterproof membrane, reduce the damage to the waterproof membrane due to local force, and achieve a better fastening effect. The gasket 3 The edge is provided with an arc-shaped chamfer 301, which also prevents the gasket 3 from being in contact with the waterproof membrane for a long time and causing damage to the waterproof membrane. The nut 4 is a galvanized nut, and the nut 4 is threadedly connected with the stem of the bolt 1, and is arranged at the end of the flowering tube 2 away from the head of the bolt 1, and a circle of skirt 401 is arranged on the nut 4 along the circumference, and the The diameter of the outer contour of the skirt 401 is larger than the diameter of the switch barrel.

When in use, referring to Fig. 4, holes are pre-drilled on the waterproof coiled material 5, the mortar leveling layer 6 and the soft foundation roof 7, and the fastening device is pre-assembled. Then put the nut 4 of the fastening device into the hole. If the process of putting it in is not smooth, you can use a small hammer to tap it properly. Finally, use a pistol drill to screw the head of the bolt 1 of the fastening device, see Figure 5. When screwing, the nut 4 rises along the stem of the bolt 1, and tightens the nut 4 at the end of the flowering tube 2 away from the head of the bolt 1. The pipe wall is extruded, so that the pipe wall of the source is scattered around in the shape of petals and is firmly connected with the soft foundation roof 7 .
