Embodiment Construction
[0015] The main construction process of the high-rise building beam-type transfer layer steel pipe support superimposed pouring one-time forming construction method of the present invention is as follows figure 1 Shown:
[0016] Step A, determine the scheme of adding reinforcement to the auxiliary steel beams of the transfer floor and the beams and slabs of the first and second floors of the transfer floor. In the structural design stage of high-rise buildings, due to consideration of wind loads and earthquake loads, the load effect is reflected in the lower beams and columns with larger cross-sectional dimensions, more reinforcement, and higher bearing capacity. During the construction of the lower part, since the upper load, construction vibration load and most of the wind load have not been applied to the structure, the beams and columns of the lower part of the structure have a large bearing capacity reserve. During the construction of the transfer floor, the bearing capa...

The invention relates to a once molding construction method of a beam-type conversion layer of a high-rise building by steel pipe supporting and laminated pouring. The once molding construction method comprises the following steps of: determining a reinforcing steel bar addition scheme of an auxiliary steel beam of a conversion layer and a first beam plate and a second beam plate lower than the conversion layer; mounting a template support frame of the second beam plate lower than the conversion layer, paving a template of the second beam plate lower than the conversion layer, manufacturing a reinforcing steel bar structure of the second beam plate lower than the conversion layer, and pouring concrete to the second beam plate lower than the conversion layer; mounting a template support plate of the first beam plate lower than the conversion layer, paving a template of the first beam plate lower than the conversion layer, and manufacturing a reinforcing steel bar structure of the first beam plate lower than the conversion layer; mounting the auxiliary steel beam of the conversion layer, mounting the template support frame of the beam plate of the conversion layer, paving the template of the beam plate of the conversion layer, and manufacturing the reinforcing steel bar structure of the beam plate of the conversion layer; pouring the concrete to the first beam plate lower than the conversion layer and the conversion layer; and dismantling the template support frame of the beam plate of the conversion layer, the auxiliary steel beam, and the template support frames of the first beam plate and the second beam plate lower than the conversion layer. According to the once molding construction method disclosed by the invention, supporting materials of the template can be reduced, the construction period is reduced, and the engineering quality of the beam plate is ensured.
Description
technical field [0001] The invention relates to a construction method for a transfer floor of a high-rise building. Background technique [0002] Since the use functions of different building floors in high-rise buildings require different space division and arrangement, different structural forms are required, and a transitional structure is set at the junction of the two structures, which is the transfer floor. The beam-slab section of the beam-type transfer floor is large, self-heavy, and difficult to construct. At present, two beam-type transfer-story formwork support schemes are commonly used in engineering for the construction of beam-type transfer floors: the load transfer method of multi-layer formwork and the superimposed pouring method of formwork support. The multi-layer formwork support of the load transfer method requires all the formwork support frames from the bottom surface to the beam slab of the transfer floor to be reserved after the concrete pouring of t...
