Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0017] The method of the present invention is based on the standard structural requirements and construction methods of the traditional full-hole fastener-type steel pipe scaffolding (refer to JGJ130-2011 safety technical specifications for fastener-type steel pipe scaffolding in building construction, etc.), adding anti-side movement diagonal braces, specifically The implementation mode is: take the building below 3 meters of general story height as an example to illustrate, as the full hall fastener type steel pipe scaffolding of formwork support, set up two steps of equal steps. In the horizontal and vertical directions of the central part of the first floor, a row of diagonal braces is respe...

The invention discloses a method for lateral displacement resistance of full-fastener-type steel tube scaffolds. The method for lateral displacement resistance of the full-fastener-type steel tube scaffolds is used for a building lower than 3 meters. The full-fastener-type steel tube scaffolds serve as building formwork supports and are erected in a mode of equal step pitch. A row of inclined supports are arranged in the center of a storey in the transverse direction, a row of inclined supports are arranged in the center of the storey in the longitudinal direction, and the height of each inclined support is equal to the step pitch of the scaffolds. The upper end of each inclined support is fixed with an upright through a rotary fastener and the lower end of each inclined support is fixed with inclined support fixing soles through rotary fasteners. The angle between each inclined support and the ground is 45degrees-60degrees. The space between every two inclined supports is equal to that of every two uprights. The method is on the basis of the standard construction requirements and the standard construction method of traditional full-fastener-type steel tube scaffolds, the lateral displacement resistant inclined supports and the inclined support fixing soles are additionally arranged, the large-wave curved instability mode of the full-fastener-type steel tube scaffolds is changed, and the overall stable bearing capacity of the full-fastener-type steel tube scaffolds is improved or the step pitch of the high and large formwork full-fastener-type steel tube scaffolds is increased under the condition of the same overall stable bearing capacity.
Description
[0001] technical field [0002] The invention relates to a formwork support technology, that is, to improve the bearing capacity of a floor formwork support through a steel pipe fastener type full hall scaffolding anti-side displacement structure, and belongs to the technical field of building construction. Background technique [0003] Mantang fastener-type steel pipe scaffolding is widely used in engineering as a floor formwork support. The bearing capacity of the steel pipe scaffolding with full fasteners as the floor formwork support is based on experiments and theoretical research, and is guaranteed by the specific structure corresponding to the experimental and theoretical bearing capacity research, forming the current national norms and safely carrying out engineering practice. [0004] In the relevant current national codes, a specific structure including vertical poles, longitudinal horizontal poles, horizontal horizontal poles, vertical scissor braces, horizontal s...
