Coiled material waterproof laying equipment and coiled material waterproof laying method

Abstract

The invention discloses coiled material waterproof laying equipment and a coiled material waterproof laying method, and belongs to the field of waterproof buildings. The equipment and method are used for integrated equipment operation in the waterproof construction processes such as coiled material unfolding, film collecting, laying, coiled material unfolding, film collecting and discharging, and the equipment comprises an unfolding shaft and a film collecting shaft which are rotationally connected to an equipment support. Core shaft tube locking devices are respectively mounted on the unfolding shaft and the film collecting shaft and are used for locking and fixing the coiled material and collecting the core shaft tube. An unfolding torque limiting device is used for providing tension required for unfolding the coiled material by the unfolding shaft. And a film collecting motor provides the film collecting tension required by the film collecting shaft for the recovery of a coiled material anti-sticking isolating film through the film collecting torque limitation. The equipment and method are mainly applied to spreading and laying of wet-laid or self-sticking waterproof coiled materials and discharging construction of the coiled materials.

Description

technical field [0001] The invention relates to construction equipment and a construction method in the field of building waterproofing, in particular to a coiled material waterproof layer laying equipment whose surface is covered with an anti-adhesive isolation film, and a coiled material waterproof laying method. Background technique [0002] Waterproof membrane is mainly used for the bottom of building walls, roofs, tunnels, highways, bridges and other places to resist external rainwater and groundwater leakage. It is a flexible building material product that can be rolled into rolls. The non-leakage connection material between objects is the first barrier for waterproofing of the entire project and plays a vital role in the entire project. [0003] At present, the commonly used waterproof membranes in building waterproofing include a type of waterproof membrane with a self-adhesive layer on the surface and an anti-adhesive barrier film on the "adhesive layer", such as "s...

AI Technical Summary

Problems solved by technology

First of all, in the process of laying the waterproof membrane, it is necessary to ensure that the unwinding of the coil and the recovery of the anti-adhesive release film are synchronized, otherwise the anti-adhesive release film will be broken during the recovery process due to the fast recovery speed and the slow unwinding speed, or The unwinding speed is fast and the recovery is not timely, resulting in the situation of laying the coiled material with film

However, in the above-mentioned prior art, the take-up roller and the unwinding roller lack a synchronous device, so it is impossible to realize the synchronization of the unwinding of the coil and the recovery process of the release film.

For example, in CN207727862U "a coiled material flat forming machine", it adopts the gear meshing mode to ensure that the laying roller and the protective film winding roller rotate synchronously, but because the coiled material radius on the waterproof coiled material support roll and the protection film in the construction work The radius of film winding on the film winding roller changes in real time, so the linear speed of film winding and unwinding changes in real time, so its synchronous rotation can only ensure that the angular velocity during the process of unwinding and winding is relatively constant, while The line speed cannot be guaranteed to be the same; another example is CN111717697A "an uncoiling and rewinding machine for laying waterproof coiled material", which adopts the active filming method of the filming motor

Therefore, above-mentioned prior art all can't guarantee suitable film tension, thus all can occur when film line speed is greater than coil material unwinding line speed, coil material anti-adhesive separation film will be pulled off; When the material unwinding line speed is low, the protective film of the coil will not be recovered in time, resulting in the occurrence of the "film" laying of the coil

Secondly, the unwinding rollers in the above-mentioned prior art all lack a device for providing coil unwinding tension, and cannot provide effective stretching tension for the unrolling coil, which in turn leads to wrinkles in the process of laying the waterproof layer of the coil and cannot meet the requirements of the waterproof layer. Defects in laying quality requirements

[0005] In addition, in CN111717697A "an uncoiling and rewinding machine for laying waterproof coiled material", the unwinding roller adopts the "expanding shaft" device of the mandrel tube as the positioning and locking device for the mandrel tube of the unwinding coil, because the mandrel tube expands The expansion principle of the shaft device (the expansion shaft is inserted into the mandrel tube of the coiled material, and the expansion unit of the expansion shaft expands so that the outer diameter of the expansion shaft becomes larger and then the coiled mandrel tube is tightened), which determines that the outer diameter of the expansion shaft is smaller than the mandrel tube The inner diameter of 10mm is the best. When the deviation of this size is too large, the expansion failure will occur. Therefore, the expansion shaft is used to tighten the coil mandrel tube, which will cause the "expansion shaft" to be unable to be inserted. Among the coil mandrel tubes whose appearance is deformed due to transportation and other factors, the defect that the above-mentioned deformed coil cannot be used by the equipment occurs.

There is no mandrel tube locking device on the winding rollers, and the anti-adhesive release film of the coil is directly wound on the winding roller, which makes it difficult to separate the anti-stick separation film from the winding roller, which seriously reduces the construction efficiency
