Description

Technical Field

[0001] The invention relates to the technical field of roof waterproof protection construction, in particular to a roof partition joint construction device and a use method thereof. Background Art

[0002] The roof surface layer of a building refers to the portion above the roof structure, including the roof screed, insulation layer, waterproof layer, rigid protective layer, and finishing layer. Surface screed joints are pre-set joints in the roof screed, rigid waterproof layer, and rigid protective layer to reduce cracks. The rigid protective layer is only formed with V-shaped grooves on the surface, known as surface screed joints. Providing a certain number of screed joints can reduce the area of a single concrete layer, thereby reducing deformation due to expansion and warping, effectively preventing and limiting the occurrence of cracks.

[0003] The construction quality of roof partition joints is difficult to control. The use of post-cutting to set partition joints can easily damage the waterproof layer. The use of wooden strips and other methods to set partition joints cannot achieve a straight and beautiful effect. Those skilled in the art have conducted research and improvements on this. For example, a concrete roof partition joint construction structure with application number CN202322120963.2 connects multiple square tubes through connecting components, which can divide the floor into several rectangles. Later, the overall gluing is performed by punching holes in the upper surface of the square tubes and injecting glue or peeling the upper surface of the square tubes from the square tubes. However, this technical solution is difficult to ensure the accurate arrangement of the square tubes and the structural strength of the device. It is necessary to preset correction blocks in advance to limit the square tubes, which increases labor intensity and cost.

[0004] Therefore, the applicant, based on many years of rich experience in design, development and actual production in the relevant industry, has studied and improved the existing structure and deficiencies, and provided a roof partition joint construction device and its use method, in order to achieve a more practical purpose.

[0036] The included angles between the limiting plate 63 and the side surfaces of the positioning shell 61 on both sides are both 135°.

[0037] The fixing frame 7 includes an annular seat 71, the outer wall of the annular seat 71 is connected with a fixing rod 72, the bottom outer side of the fixing rod 72 is connected with a positioning column 73, a threaded tube 74 passes through the annular seat 71, the upper part of the outer wall of the threaded tube 74 is connected with a retaining ring 75, and the top of the retaining ring 75 is circumferentially connected with a plurality of shifting blocks 76 to facilitate the rotational installation of the threaded tube 74, and the threaded tube 74 is connected to the threaded hole 62 through a thread.

[0040] The roofing surface layer 1 includes a concrete base layer 11, a waterproof layer 12, and a protective layer 13, which are arranged in order from bottom to top. The concrete base layer 11 serves as the bottom structure and mainly provides support and leveling.

The annular seat 71 is placed on the top of the positioning shell 61. The positioning column 73 at the bottom of the fixing rod 72 can be inserted into the guide hole 53. The threaded tube 74 is inserted into the threaded hole 62 and rotated. The retaining ring 75 can abut against the upper surface of the annular seat 71 for fixed clamping.

[0046] The square tube 4, the docking shell 5, the assembly seat 6 and the fixing frame 7 form an integral body, and glue can be injected into the interior along the threaded tube 74 to ensure the width, straightness and aesthetics of the partition seam 3.

[0047] In summary, the present invention has a reasonable structural design. It utilizes a roof surface layer in combination with a rigid protective layer for waterproof protection. The concrete base serves as a bottom structure to support and level the floor. The waterproof layer can effectively prevent moisture from penetrating into the base. The protective layer can withstand long-term trampling and friction without being easily damaged. After the fine stone concrete is poured, a relatively uniform and dense protective layer is formed, achieving a good protective effect.

[0048] In the present invention, the rigid protective layer is divided into several rectangular areas by grid seams. The square tubes in the grid seams are evenly spaced and distributed in a cross shape around the assembly seat. The docking shell extends into the assembly seat and abuts against the limit plate. The end of the injection tube extends into the opening of the docking shell. The annular seat is located on the top of the positioning shell. The positioning column and the guide hole are matched and docked. The installation is accurate and convenient, and the structural strength of the device can be guaranteed.

[0049] In the present invention, the threaded tube can be inserted into the threaded hole for rotation, and the retaining ring is used to fix and clamp the annular seat, so that the square tube, the docking shell, the assembly seat and the fixing frame form a whole, which is convenient for overall glue injection inside and is beneficial to ensuring the width, straightness and aesthetics of the partition seam.
