Description

Waterproof laying equipment and waterproof laying method for coiled material

Technical Field

The invention relates to construction equipment and a construction method thereof in the field of building waterproofing, in particular to coiled material waterproof layer laying equipment with an anti-adhesion isolating membrane covered on the surface and a coiled material waterproof laying method.

Background

The waterproof roll is a flexible building material product which can be curled into a roll shape and is mainly used for resisting external rainwater and underground water leakage at the positions under building walls, roofs, tunnels, highways, bridges and the like, is used as a leakage-free connecting material between an engineering foundation and a building, is a first barrier for waterproofing of the whole engineering, and plays a vital role in the whole engineering.

The present commonly used waterproof coiled material in building waterproofing comprises a waterproof coiled material with a self-adhesive layer on the surface and an anti-sticking isolating film covered on the self-adhesive layer, such as a self-adhesive waterproof coiled material, a wet-laid waterproof coiled material and the like. However, most of the existing construction processes are generally completed by manual operation, and the defects or disadvantages of low construction efficiency, high labor intensity, high labor cost, huge volume of waste anti-sticking isolation film garbage generated, serious environmental pollution and the like exist. In addition, the manual film tearing is also easy to cause the phenomena of low construction efficiency and material waste because the front and the back of the adhesive layer of the coiled material are mistakenly touched and bonded together.

Through searching related technical documents, the inventor finds that the related published documents comprise a Chinese utility model patent with publication number CN207727862U and publication date of 2020, 08 and 14 days, "a roll material tiling forming machine", and a Chinese invention patent application with publication number CN111717697A and publication date of 2020, 8 and 14 days, "an uncoiling and coiling machine for laying waterproof roll materials", although the above-mentioned materials are replaced by manual film tearing and manual laying by mechanical construction, and anti-sticking isolating film recovery devices are arranged, the defects still exist. Firstly, in waterproofing membrane laying process, must guarantee that the coiled material exhibition is rolled up and antiseized barrier film retrieves synchronous, otherwise can take place to cause antiseized barrier film to be broken in the recovery process because of retrieving fast that the speed of roll-up is slow, perhaps the exhibition is rolled up fast and retrieve the condition emergence that untimely causes the laying of coiled material area membrane. And the receipts membrane roller among the above-mentioned prior art all lacks synchronizer with the exhibition roll roller, can't realize its coiled material exhibition book and antiseized barrier film recovery process synchronous. In CN207727862U, "a roll material laying forming machine", it adopts a gear engagement mode to ensure that the laying roll and the protective film winding roll rotate synchronously, but because the roll material radius on the waterproof roll material supporting roll and the film collecting radius on the protective film winding roll change in real time during the construction operation, the linear velocity of the film collecting and the film spreading changes in real time, so that the synchronous rotation can only ensure that the angular velocity in the processes of film spreading and film collecting is relatively constant, and the linear velocity cannot be ensured to be the same; also like CN111717697A "an uncoiling and coiling machine for laying waterproof rolls", it adopts the active film coiling mode of a film coiling motor. Therefore, the prior art cannot ensure proper film collecting tension, so that the anti-sticking isolating film of the coiled material is broken when the film collecting linear speed is greater than the coiled material unwinding linear speed; when receiving the membrane linear velocity and being less than coiled material exhibition book linear velocity, the coiled material protection film will unable in time be retrieved, causes the condition emergence that the coiled material "takes the membrane" laid. Secondly, the tensile device that provides of coiled material exhibition book is all lacked to the exhibition book roller among the above-mentioned prior art, can't provide effectual tensile to the exhibition book coiled material, and then leads to coiled material waterproof layer laying process to produce the defect that quality requirement that the waterproof layer laid can't be satisfied such as fold.

In addition, in CN111717697A "lay waterproofing membrane's uncoiling rolling machine", the roll-out roll adopts central siphon "axle expansion" device as the location locking device of roll-out coiled material central siphon, because of the bloated tight principle of central siphon axle expansion device (the axle that expands inserts in the coiled material central siphon, the bloated tight unit inflation of axle that expands causes the axle external diameter grow of expanding and then the bloated coiled material central siphon), it is best to decide in the 10mm scope that its axle external diameter size that expands is less than central siphon internal diameter size, when this kind of size deviation is too big, then the condition that can expand the inefficacy takes place, so adopt the mode of the bloated tight coiled material central siphon of the axle that expands will lead to "the axle" can't insert because of the transport in the middle of the coiled material central siphon that factor produced outward appearance deformation, cause the defect emergence of the unable quilt equipment use of above-mentioned outward appearance deformation's coiled material. All lack core shaft pipe locking device on receiving the membrane roller, the antiseized barrier film of coiled material directly twines on receiving the membrane roller, leads to the antiseized barrier film of coiled material and receives the membrane roller separation difficulty, has seriously reduced the efficiency of construction.

The coiled material laying and blanking method comprises the following steps:

firstly, preparation work of laying and blanking of coiled materials:

mounting the coil, separating the upper half bearings of the

semicircular bearings

201 and 202, removing the coil take-up spool 21 from the semicircular bearing 201/202 → removing the coil mandrel tube locking clip 222 on the coil take-up spool 21 furthest from the first actuator (the coil mandrel tube locking clip 221 on the proximal end from the first actuator remains locked with the take-up spool) → inserting the coil take-up spool 21 into the coil mandrel, pressing one end of the coiled material core shaft tube into the coiled material core shaft tube locking clamp 221 which is near the first transmission device → remounting the locking clamp 222 which is taken off on the unwinding shaft and pressing the locking clamp into the coiled material core shaft tube, positioning and locking the locking clamp and the unwinding shaft → placing the unwinding shaft and the coiled material fixed on the unwinding shaft back into the semicircular bearing 201/202, and the upper half of the split semicircular bearing 201/202 is reinstalled. At this point, the coil installation is complete.

Installing the film winding core shaft tube, taking out the film winding core shaft tube locking chuck 322 (the core shaft tube locking chuck 321 and the film winding shaft which are the most proximal ends of the third transmission devices 36 are always kept in a locking state) on the film winding shaft 31, pressing the film winding shaft 31 into the film winding core shaft tube 310, pressing one end of the film winding core shaft tube into the core shaft tube locking chuck 321, reinstalling the taken-off locking chuck 322 on the film winding shaft, pressing the locking chuck 322 into the film winding core shaft tube, and positioning and locking the chuck and the film winding shaft. And finishing the installation of the film-winding core shaft tube.

Uncovering the anti-sticking isolating film on the lower surface of the coiled material installed on the coiled material winding device, and winding and fixing the anti-sticking isolating film on the film-winding mandrel pipe 310; and (3) turning on a power switch in the electric control device to supply power to each electric device of the equipment, and at the moment, the film collecting motor 34 works and drives the film collecting shaft 31 to rotate to further tighten the anti-sticking isolation film of the coiled material on the film collecting core shaft tube 310.

And secondly, laying a waterproof layer of the coiled material, aligning the equipment on a base surface to be constructed, holding the outermost end of the coiled material and pulling the coiled material out of the equipment, stepping on the coiled material out of the equipment by one person for positioning, pulling or pushing the equipment in the opposite direction by another person, controlling the running direction of the equipment through an equipment handrail, laying the uncoiled coiled material on the waterproof base surface, and synchronously rotating a film collecting shaft to recover an anti-sticking isolation film of the uncoiled coiled material.

When the equipment is pulled or pushed to perform uncoiling and paving on the waterproof base surface, the torque borne by the uncoiling shaft 21 is gradually increased to provide uncoiling tension for the coiled material, when the actual torque borne by the uncoiling shaft 21 is larger than or equal to the set torque of the magnetic powder brake 231, the magnetic powder brake 231 slips, and at the moment, the uncoiling shaft 21 rotates passively and starts to perform coiled material uncoiling and paving.

When the film is rolled up and unwound by the coiled material, the linear speed of the film winding is always greater than the speed of the film winding and unwinding, so that the film winding torque actually borne by the film winding shaft is always greater than or equal to the set torque of the magnetic powder clutch 331, that is, the magnetic powder clutch 331 is always in a slipping state while the film winding shaft 31 is winding the film, thereby ensuring that the processes of the film winding and unwinding of the coiled material are always synchronous.

When pulling/pushing equipment stops, the unwinding shaft stops rotating, at the moment, the film winding shaft 31 continuously tensions the anti-sticking isolation film of the coiled material, when the torque borne by the film winding shaft 31 is larger than or equal to the torque set value of the magnetic powder clutch 331, the magnetic powder clutch 331 slips, the film winding shaft stops rotating, and the film winding stops.

Thirdly, blanking of coiled materials: the invention is used as the material for the coiled material when the waterproof construction parts which are not suitable for being directly unrolled and laid by using equipment, such as irregular-shaped base surfaces (such as structural parts of a bottom plate foundation pit, a foundation beam, a top plate high-low span and the like) or facades (such as structural parts of a ground storehouse vertical wall, a top plate main body facade, a roof parapet and the like) are used: and locking wheels below the equipment support, preventing the equipment from moving, holding one end of the coiled material and pulling the end out of the equipment to the length required by the waterproof base surface, synchronously recovering the anti-sticking isolating film of the coiled material in the process, cutting the coiled material according to the required material length, and finishing the blanking process of the coiled material.
