Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a construction structure of a small opening in an aluminum mold with reserved bolt holes for a climbing frame support. Background Art

[0002] At present, the attached lifting scaffold (hereinafter referred to as climbing frame) is widely used in many high-rise and super high-rise buildings. Its wall-mounted support is fastened to the building structure through through-wall bolts. During the construction process, the accuracy of the reserved position of the bolt hole of the wall-mounted support is very important. When the structural formwork system selects the aluminum alloy formwork (hereinafter referred to as aluminum formwork) system, the reservation of the bolt hole of the wall-mounted support is to open the hole in advance during the processing of the exterior wall aluminum formwork. However, the diameter of the bolt of the climbing frame support is greater than or equal to 32mm. According to the rules of the aluminum formwork rental industry, if the opening size is less than 10mm, no additional fee will be charged. If the opening size is greater than or equal to 10mm, the billing will increase dramatically. The first traditional reservation scheme requires the PVC sleeve to be embedded when tying the steel bars, but when pouring concrete, the PVC sleeve is very easy to deviate, resulting in inaccurate reserved hole positions. After removing the formwork, it is necessary to open holes again on the main structure, which increases the construction cost. The most important thing is to destroy the integrity of the main structure, thereby affecting the safety performance of the main structure. The second traditional reservation solution requires drilling holes in the aluminum formwork in advance. The diameter of the climbing frame support bolts is greater than or equal to 32mm. According to the rules of the aluminum formwork rental industry, if the hole size is greater than or equal to 10mm, the billing will increase dramatically, which will significantly increase the construction cost. Therefore, the present utility model was born. Utility Model Content
