Description

PVC trapezoidal roofing dividing strip Technical Field The utility model relates to the technical field of roofing engineering, in particular to a PVC trapezoid roofing dividing strip. Background In the construction of a clean industrial factory building with a steel structure, the roof area of the building is obviously larger than that of conventional buildings such as houses, and the casting amount of the disposable rigid concrete waterproof protective layer is huge. In addition, the steel structure is easily influenced by external temperature change and other factors, and generates trace deformation, so that the cracking prevention control difficulty of the roof waterproof protective layer is extremely high. With the continuous improvement of the score ratio of roof subsection engineering in various provide quality goods or brilliant prize scores, the construction quality of the large-span roof separation joint is increasingly concerned. The roofing dividing seam is used as a manual seam arranged on the roofing leveling layer and the rigid protective layer, and the expansion and the warping are reduced by reducing the unit area, so that the roofing dividing seam is a key measure for preventing irregular cracking of the roofing. However, the existing roof separation joint construction process has a plurality of defects. The traditional separation joint material has poor effects in stress dispersion and deformation resistance, is difficult to meet the deformation requirement of a steel structure roof, has unreasonable inward tilting waterproof coating, cannot accurately coat each part in the crack, has low prefabrication degree of the material in the construction process, has low construction efficiency and higher cost, and is difficult to meet the requirement of modern industrial factory building construction. In view of the above, the present utility model provides a PVC ladder roofing separator strip to solve the above problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a PVC trapezoid roof dividing strip, which solves the defects of the existing roof dividing seam construction process. The traditional separation joint material has poor effects in stress dispersion and deformation resistance, is difficult to meet the deformation requirement of a steel structure roof, has unreasonable inward tilting waterproof coating, cannot accurately coat each part in the crack, has low prefabrication degree of the material in the construction process, has low construction efficiency and higher cost, and is difficult to meet the requirement of modern industrial factory building construction. The PVC trapezoid roof separation strip comprises a roof separation assembly, wherein the roof separation assembly comprises a separation strip body, the separation strip body is of an inverted trapezoid shape with a wide upper part and a narrow lower part, an inner cavity and liquid outlet holes are formed in the separation strip body, the inner cavity is formed in the separation strip body, the liquid outlet holes are formed in the side ends of the inner cavity, the liquid outlet holes are distributed at the two ends of the separation strip body, and the liquid outlet holes are used for uniformly outputting waterproof paint. Preferably, the internal groove is arranged in the separating strip body, and the internal groove is used for dividing the separating strip body into two parts, so that the separating strip body has stronger deformability and can bear larger extrusion force of concrete expansion at two ends. Preferably, the roof separation assembly further comprises a rubber cushion, the rubber cushion is also in an inverted trapezoid shape with a wide upper part and a narrow lower part, the rubber cushion is fixed in the inner groove, and the rubber cushion is used for absorbing extrusion force of the separation strip bodies at two ends. Preferably, the roof separation assembly further comprises a waterproof cover plate, the waterproof cover plate is mounted at the top end of the separation strip body, and the waterproof cover plate is used for being waterproof. Preferably, the spout has been seted up to waterproof apron bottom, separate strip body top fixedly connected with slide rail, spout sliding connection is in the slide rail. Preferably, a filling port is formed in the top end of the sliding rail, and the filling port is used for pouring waterproof paint into the inner cavity. The utility model discloses a PVC trapezoid roof dividing strip which has the beneficial effects that the PVC trapezoid roof dividing strip is designed by adopting a trapezoid cross section bevel edge, can more efficiently disperse stress generated by temperature change and material shrinkage and expansion, has higher hardness, has stronger bending resistance than an extruded sheet, effectively ensures the structural stability of a roof, and can uniformly diffuse waterproof coating into a joi
