Embodiment Construction

[0042] The following is attached figure 1 to attach Figure 11 The present invention is further described in detail with specific examples.

[0043] It should be noted that the structural beams and slabs include structural beams and structural slabs. The roof back reinforcement of the structural beams and slabs in this embodiment takes the roof back reinforcement of the basement roof 2 as an example. The basement roof layer is referred to as B0 floor below, and the basement negative floor is referred to as B1 The second floor of the basement is referred to as the B2 floor, and the third floor of the basement is referred to as the B3 floor. Of course, the method of this embodiment is also applicable to the reinforcement of other structural beams and slabs, and is not limited to the reinforcement of the basement roof 2 .

[0044]It should also be noted that the top-return belt area referred to in the present invention refers to a band-shaped area artificially divided on the st...

Abstract

The invention relates to the field of buildings, and provides a structural beam plate back-to-top reinforcing method. The structural beam plate back-to-top reinforcing method comprises the following steps that a to-be-reinforced floor arranged in a back-to-top zone area and a corresponding position on the to-be-reinforced floor are preliminarily determined according to a load on a structural beam plate, and a back-to-top supporting assembly is arranged below the back-to-top zone area; a back-to-top overall model is established; the bearing capacity of the structural beam plate is judged according to a model calculation result; if the bearing capacity is insufficient, the setting number of the back-to-top zone areas is continuously increased on the same floor and/or the setting number of the back-to-top zone areas is increased on the next floor, and then re-modeling is carried out until the bearing capacity meets the preset requirement; and setting of the final back-to-top zone area is determined, and construction of the back-to-top supporting assembly of the corresponding area is completed. A basement top plate is divided into a plurality of span plates by providing the back-to-top zone, the plate span of the basement top plate is reduced, the bearing capacity of the basement top plate is improved, a large number of full framing does not need to be erected, and therefore the construction cost is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a roof back reinforcement method for structural beams and slabs. Background technique [0002] During the construction process of the construction project, temporary construction operations such as piled loads and heavy vehicles on the basement roof are unavoidable, corresponding to the temporary construction load. Due to construction characteristics and work efficiency requirements, the temporary construction load generated by large and medium-sized engineering vehicles is generally larger , and is generally larger than the design load of the basement roof, so under the action of this type of construction load, there will be safety hazards or even damage risks to the basement roof structure. This kind of load value is large and the action time is short, which only occurs occasionally in the construction stage. If this part of the load is considered in the design pr...
