Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coiled material laying, and more specifically, particularly relates to a pre-laid waterproof coiled material connection structure. Background Art
[0002] At present, since its advent, polymer self-adhesive membrane waterproofing roll has been recognized by more and more people for its convenient construction method and reliable waterproof performance. In just a few years, it has achieved rapid development in the domestic waterproofing industry and has been used in various types of building waterproofing.
[0003] Based on the above, the inventors have discovered the following problems: Since there are many application sites for waterproof membranes and the sizes of the sites are also different, it is always necessary to butt-joint two waterproof membranes. Currently, when butt-jointing two waterproof membranes, the staff directly sets the two waterproof membranes relative to each other, and then squeezes sealant into the butt joint. After the sealant dries, a sealed connection between the two waterproof membranes can be achieved. During the above operation, there is a defect that the staff may accidentally move their hands, thereby causing the butt joint between the two waterproof membranes to be misaligned, affecting the later application of the waterproof membrane.
[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a pre-laid waterproof membrane connection structure is provided, in order to achieve a more practical purpose. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a pre-laid waterproofing membrane connection structure to solve the problem of misalignment when the existing waterproofing membranes are butt-jointed.
[0006] The purpose and effect of the pre-laid waterproofing coiled material connection structure of the utility model are achieved by the following specific technical means:
[0007] A pre-laid waterproofing membrane connection structure comprises a first membrane and a second membrane, wherein a fixing plate is provided at the connection between the first membrane and the second membrane, a mounting portion is provided on the fixing plate, a lower pressure plate is provided on the upper portion of the fixing plate, a connecting groove is provided in the middle portion of the fixing plate, fixing pieces are installed at both ends of the fixing plate, a push rod is provided inside the fixing piece, a cushion block is installed at the bottom of the push rod, limiting columns are installed on both sides of the cushion block, a notch is provided on the side of the fixing piece, a limiting groove is provided on the side of the fixing piece at the lower portion of the notch, and the limiting column is located inside the limiting groove.
[0008] Furthermore, the diameter of the limiting column is matched with the width of the notch and the limiting groove, the notch and the limiting groove form an L shape, and the diameter of the cushion block is matched with the inner diameter of the fixing member.
[0009] Furthermore, there are two push rods, which are respectively located at the two ends of the fixed plate. The upper parts of the two push rods are connected by a cross plate. A push column is installed at the lower part of the cross plate. The cross plate is connected to the upper surface of the lower pressure plate through the push column.
[0010] Furthermore, connecting ears are installed on both sides of the upper part of the fixing member, a movable plate is installed on the push rod, a spring is installed at the lower end of the movable plate, and the lower end of the spring is connected to the connecting ears.
[0011] Furthermore, the size of the mounting portion is matched with the size of the lower pressing plate, and anti-slip grooves are provided on the inner side of the mounting portion and the lower pressing plate.
[0012] Furthermore, the connection ends of the first coil and the second coil pass through the connection groove and are connected to the lower part of the fixing plate.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The utility model drives the horizontal plate and the movable plate to move by moving the push rod downward. When the horizontal plate moves downward, it can drive the pushing column to move downward synchronously. When the pushing column moves downward, it can push the lower pressure plate to move downward. When the lower pressure plate moves downward, it gradually enters the inner side of the installation part and contacts with the upper surface of the connection between the first coil and the second coil. By continuously moving the lower pressure plate downward, force can be applied to the connection between the first coil and the second coil. The anti-slip groove can prevent the first coil and the second coil from moving out of the inside of the connecting groove. The two connected coils are placed in the connecting groove at the same time to fix them, thereby solving the problem of misalignment when the waterproof coils are connected.

The inner diameter of the push rods 12 is adapted, the number of the push rods 12 is two, and they are respectively located at the two ends of the fixed plate 3. The upper parts of the two push rods 12 are connected by a cross plate 16, and a pushing column 17 is installed at the lower part of the cross plate 16. The cross plate 16 is connected to the upper surface of the lower pressure plate 18 through the pushing column 17. When the push rods 12 move downward, the cross plate 16 and the movable plate 13 can be driven to move. When the cross plate 16 moves downward, the pushing column 17 can be driven to move downward synchronously. When the pushing column 17 moves downward, the lower pressure plate 18 can be pushed downward. When the lower pressure plate 18 moves downward, it gradually enters the inner side of the mounting portion 4 and contacts the upper surface of the connection between the first coil 1 and the second coil 2. By continuously moving the lower pressure plate 18 downward, force can be applied to the connection between the first coil 1 and the second coil 2, and the anti-slip groove 5 can prevent the first coil 1 and the second coil 2 from moving out of the inside of the connecting groove 6.
