Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to the technical field of metal roof supports, and specifically refers to an adjustable support for controlling the slope of a metal roof. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc.

[0003] With the development of modern architecture, metal roofs are increasingly used, and often appear in the roof construction of large public buildings such as airports and factories. However, for roofs with large slope changes or special-shaped structures, when installing the main purlin, it is necessary to continuously adjust the angle of the purlin support according to the slope of the roof to ensure that the shape of the main purlin meets the design requirements. Due to the small demand for this type of structure, there are almost no mature adjustable supports on the market that can be used to control the slope of metal roofs. The existing purlin supports are all fixed supports. One approach is to cut, adjust, weld and process the fixed supports on site so that the slope of the main purlin meets the requirements. This approach is not only time-consuming and labor-intensive, but also easily causes the problem of uneven installation of the purlins. A more conventional approach is to customize the base of the fixed support, produce it at a certain angle, and then transport it to the site for welding and use, so as to achieve the problem of adjusting the angle of the metal roof support. However, due to the frequent construction errors between the site and the drawing design, after multiple magnifications, the produced supports often cannot be used on site, resulting in a large loss of construction period and materials.

[0004] Therefore, it is desired to provide an adjustable support for controlling the slope of a metal roof, which can adjust the angle according to the slope of the roof, save time and labor, and improve construction quality and efficiency. Utility Model Content
