Embodiment Construction
[0025] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.
[0026] see figure 1 , the embodiment of the present invention provides a kind of garage top back construction method, wherein, comprises the following steps:
[0027] Step S1: According to the construction situation on the top roof 7a, analyze and determine several load-bearing distribution points of the top roof 7a;
[0028] Step S2: A transition steel beam 1 is straddled between the adjacent structural beams 2 where the load-bearing distribution point of the top floor 7a is located, and the load of the load-bearing distribution point is transferred to the corresponding structural beam 2, that is, the The surface load of the top floor 7a is converted into the line load of the converted steel beam 1 during construction such as stacking and driving, so as to avoid the load caused by the construction on the top floor 7a with...

The invention discloses a garage back-jacking construction method and a back-jacking structure, and belongs to the technical field of back-jacking construction. According to the technical scheme, the garage back-jacking construction method comprises the following steps that bearing load distribution points of a top-layer top plate are determined according to the construction condition; a conversion steel beam is arranged between the structural beams corresponding to the bearing load distribution points in a spanning mode; determining a structural beam needing to be reinforced and the size of a reverse top steel beam used for reinforcing the structural beam according to the erecting condition of the conversion steel beam; in each layer of garage, a reverse top steel beam is additionally arranged on the bottom face of a structural beam needing to be reinforced; and a reverse jacking steel pipe is vertically arranged between the reverse jacking steel beam and the corresponding structural beam of the lower-layer top plate or between the reverse jacking steel beam and the foundation structure. The garage back-jacking construction method has the beneficial effects that the garage back-jacking construction method is convenient and fast to construct, cost-saving, simple, convenient and attractive, a stress system is controllable, and the garage back-jacking structure is convenient and fast to construct, simple in structure, reasonable in layout, convenient to disassemble subsequently and cost-saving.
Description
technical field [0001] The invention relates to the technical field of roof back construction, in particular to a garage roof back construction method and a back roof structure. Background technique [0002] In construction engineering, the construction site on the construction site is getting smaller and smaller, and the roof of the underground garage after construction often needs to be loaded, driven, and constructed; because the design load of the construction garage often cannot meet the requirements of the construction load, it is necessary to carry out the construction of the underground garage. The top plate is back supported. [0003] At present, the roofing of the garage is often carried out through the supporting frame (steel pipe fastener frame, disc buckle frame, wheel buckle frame, etc.), resulting in a full house. Slow, inconvenient construction, poor construction effect, and uncontrollable overall stress system. [0004] How to solve the above technical pro...
