Description
TECHNICAL FIELD
[0001] The utility model relates to building construction technical field especially relates to a waterproofing membrane's rolling spreading device. BACKGROUND
[0002] When waterproofing membrane is constructed, because the membrane is in the shape of a roll, it needs to be flattened to ensure that the soft pad of the membrane is closely attached to the building surface, thus achieving effective sealing.
[0003] The width of the membrane is fixed, and when it is laid on a building floor, it needs to be connected horizontally in turn, generally in parallel and in the same direction, to ensure close attachment. Usually, the long edges are connected in upper and lower layers, and during the connecting operation, in order to ensure the sealing performance of the connection, the membrane laid on the upper layer needs to be spread after being heated and rolled, and the oil is pressed out and the upper layer of waterproof material is pressed tightly against the material laid on the lower layer, so that the two layers of membrane are spread flat, the edges are overlapped, no gaps are ensured, and the two layers are bonded as a whole, thus achieving the sealing effect.
[0004] The operation method has the following disadvantages: sometimes it cannot be completed at one time, and the connection position needs to be rolled multiple times to press out the oil, and after the oil is solidified and dried, the two layers of membrane can be firmly bonded, and multiple rolling is required to bond the two layers tightly, ensure no gaps, and ensure close adhesion to the floor, which requires more working hours. The current method is to use a roller, a support is passed through the middle of the roller, and then the roller is rolled back and forth. This single-roller rolling method is not convenient for construction because the long-time winding shape of the membrane produces a curling force, which causes the rear end to be raised after the front end is flattened, resulting in continuous raising and flattening of the membrane. Therefore, the adhesion force is required to change the curling characteristics of the waterproof membrane, and the roller needs to be rolled repeatedly and continuously, and at the same time, the membrane needs to be heated to make it spread flat. When the two layers of waterproof membrane are overlapped, the operation is more difficult, the labor intensity is high, and a long time of repeated rolling is required.
[0005] Therefore, the utility model designs a waterproofing membrane rolling spreading device to solve the above problems. CONTENT OF THE UTILITY MODEL
