Description

Technical Field

[0001] The utility model relates to the technical field of scaffold installation, in particular to a scaffold anchoring member system used in curtain wall panel construction technology. Background Art

[0002] During the construction of building frame curtain wall, double-row scaffolding is usually used as the construction platform for workers to install. The scaffolding is tied to the main structure to maintain the overall stability of the scaffolding. The scaffolding is tied in two steps and three spans, that is, the scaffolding has two steps (the step height is generally set to 1.8 meters), and the span is set to 1.8 meters or 2 meters. This requires a height of 3.6 meters. A span of 3.6 meters or 4 meters requires four ties with the main structure. When the curtain wall panel cannot be installed and the scaffolding needs to be dismantled, the dismantling work is stopped after the first step is dismantled. The curtain wall panel installation workers will tie the ties at the ties. The panels that cannot be installed are installed and glued, and then the scaffolding workers remove the next scaffolding. This work is repeated in a cycle, which is very inconvenient, with many processes, a long construction period, and low work efficiency. It requires close cooperation between scaffolding workers, curtain wall installers, and glue workers, and the construction is difficult. Moreover, when installing a large area of ​​curtain wall, the panels that cannot be installed at the tie points need to be selected, stored in one place, and renumbered and marked at the locations where they need to be installed later, which reduces work efficiency and increases the work of selection, handling, storage, secondary transportation, and re-installation, which prolongs the construction period and increases construction costs.

[0103] The weld foot height refers to the distance from the bottom surface to the highest part on both sides of the weld or in multiple layers of surfacing during the welding process. This parameter has an important impact on the quality and effect of welding, because it not only affects the strength and sealing of the weld, but also affects the heat-affected zone and deformation degree of the weld. If the weld foot height is too high, the size of the heat-affected zone will increase, resulting in excessive deformation, while if it is too low, it will affect the strength and sealing of the weld. Therefore, in welding, it is necessary to determine the size of the weld foot height according to the requirements and specific circumstances of the welding. In one embodiment of the present scheme, the weld foot height is 4mm, which can better meet the welding quality requirements.

[0162] Through the scheme of the embodiment of the utility model, the analysis and calculation results meet the requirements of the specification. The technical scheme solves the problem of scaffolding wall tie rods for frame curtain wall panels with gaps greater than or equal to 10mm, and achieves the goal of still using scaffolding to construct frame curtain walls. The curtain wall panels can be installed in a closed manner at one time, without having to drop the panels at the connection position, and can be installed by patching the holes when the scaffolding is dismantled in the future, thereby improving the installation efficiency, shortening the installation period, reducing the cost, and eliminating the additional work of multiple transportation, storage and preservation of panels that cannot be installed at one time due to the traditional tie method; the design and construction process technology of the scheme are scientific and reasonable, with strong versatility, suitable for the use of scaffolding tie rods for frame curtain wall systems, can be used in different projects, saves materials and is environmentally friendly, can be repeatedly used in construction, and can be used in multiple projects, with a high degree of assembly.

[0163] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
