Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to the field of roof arc chamfering construction technology, specifically referring to a one-time forming tool for roof arc chamfering. Background Technology
[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.
[0003] In the construction of building structures and decoration, traditional roof chamfering largely relies on manual labor. Workers depend on experience to control the curvature of the chamfer and apply mortar. During construction, the mortar material cannot be directly formed into a curved surface; it must first be roughly shaped into a polygonal groove, and then further refined through multiple manual processes. Figure 1 As shown, the parapet wall 1 is set vertically and along the front-to-back direction. At the right base of the parapet wall 1, a curved chamfer 2 needs to be set along the front-to-back direction. First, a triangular groove shape (i.e.,...) is created. Figure 1 The initial construction of the shape by on-site workers (3) followed by subsequent manual operations, using mortar to fill the two corners (i.e. Figure 1 The process of completing the curved chamfer requires filling and perfecting part 4) before construction. This method is not only inefficient and affects the construction progress, but also has poor results. The construction quality largely depends on the experience and skill level of the workers, making it difficult to ensure that the curvature of the curved chamfer flashing is uniform and consistent, resulting in an unsightly roof appearance and possibly even affecting the drainage function.
[0004] Therefore, it is desirable to provide a tool for one-time forming of curved roof chamfers, which can form curved roof chamfers in one step, with good forming effect, improving construction quality and efficiency. Utility Model Content

[0041] In use, during the construction of the curved chamfer 2 on the roof, after the initial shape 3 is formed by the on-site workers, this utility model is placed on the initial shape 3, so that the curved plastic plate 6 abuts against the initial shape 3. Then, cement mortar is poured in through the cement mortar inlet 14, and force is applied to the operating handle 7 exposed on the second curved plate 9, so that the lower end of the operating handle 7 moves in the first slide groove and the second slide groove 15 along the arc direction of the first curved plate 8 and the arc direction of the second curved plate 9, respectively. The curved plastic plate 6 is moved along its arc direction, no longer blocking some or all of the perforations 13. Cement mortar can flow in through the perforations 13 to fill the part 4 that needs to be filled to complete the curved chamfer. By moving the operating handle 7 back and forth, the curved plastic plate 6 is moved back and forth, so that cement mortar can be repeatedly applied to the initial construction shape 3 of the workers on site until a complete curved chamfer shape is formed (the curvature of the curved plastic plate 6 is the curvature of the roof curved chamfer 2). The construction is then completed.
[0042] Therefore, using this invention, cement mortar is poured into the cavity through the cement mortar inlet. The operating handle slides back and forth in the first and second sliding grooves, causing the curved shaping plate to move repeatedly. Through perforations, cement mortar can flow in during the movement of the curved shaping plate, thus filling the area requiring further filling to complete the curved chamfer, forming the curved chamfer surface layer. Therefore, this invention can effectively utilize tools to fill and shape the required areas, achieving one-time molding and completion, with good shaping, consistent curvature control, and excellent construction results.
[0043] In summary, the roof arc chamfering one-time forming tool of this utility model can form roof arc chamfers in one step, with good forming effect, improving construction quality and efficiency. It has an ingenious design, simple structure, easy manufacturing, and low manufacturing cost, making it suitable for large-scale promotion and application.
