Description

Template supporting system for integrally pouring beam plate and beam bottom L-shaped hanging plate
Technical Field
The invention relates to a beam slab pouring formwork support system in a cast-in-place concrete factory building, in particular to a formwork support system for integrally pouring a beam slab and a beam bottom L-shaped hanging plate.
Background
For a concrete frame structure factory building with high cast-in-situ large-span layer height (for example, a factory building with the layer height of more than 6 meters and the span of more than 8 meters), the conventional construction method is as follows: firstly pouring a foundation slab of a factory building, building a pouring template support frame of an upper frame beam slab on the completed foundation slab, constructing a concrete pouring template system of an upper frame beam and slab on the upper part of the pouring template support frame, and pouring concrete after binding steel bars of the beam and slab to form an integral structure of the upper concrete beam and slab; the large-span high-rise factory building, under the peripheral outside roof beam of upper concrete beam slab, there is large-span door and window generally designed, because the high range of about 3 meters of door and window of large-span is high, in order to lighten the load of the upper concrete frame beam, there is L-shaped cast-in-place concrete link plate between roof and upper frame beam bottom of large-span door and window, L-shaped cast-in-place concrete link plate and concrete beam on its roof, form a C-shaped concrete integral structure, install the large-span door and window again below L-shaped cast-in-place concrete link plate; the structure not only reduces the load of the upper layer concrete beam and saves the concrete member material, but also meets the installation requirement of doors and windows of a factory building; aiming at the commonly adopted concrete beam and the lower L-shaped hanging plate structure, the prior art is to finish construction by respectively supporting a concrete pouring template of a beam plate and a concrete pouring template of an L-shaped hanging plate and adopting a mode of pouring the concrete beam plate and the lower hanging plate step by step, namely, firstly supporting the concrete pouring template of an upper frame beam plate and finishing concrete pouring, after the concrete strength of the upper frame beam plate reaches the dismantling standard, dismantling the pouring template of the upper frame beam plate, secondly supporting the template of the L-shaped cast-in-place concrete hanging plate, and secondarily pouring the L-shaped cast-in-place concrete hanging plate; when the concrete pouring of the L-shaped cast-in-place concrete hanging plate is carried out, as the top of the concrete hanging plate is sealed by the poured concrete beam, only a concrete pouring hopper which is inclined outwards can be arranged, so that the casting of the L-shaped cast-in-place concrete hanging plate is realized; the conventionally employed construction method has the following problems: (1) The beam slab and the L-shaped hanging plate are erected and poured in a repeated mode, so that the time consumption is long, and the construction time is greatly prolonged; (2) The concrete of the beam plate and the L-shaped hanging plate is poured in batches, and a stubble joint gap is formed at the joint of the beam plate and the L-shaped hanging plate, so that the water leakage phenomenon is easy to occur; (3) After the pouring of the L-shaped concrete hanging plate is completed, chiseling and removing treatment is required to be carried out on the concrete convex blocks formed by the pouring hopper, so that time and material are consumed, and the appearance of the outer vertical face of the factory building is influenced; if the concrete pouring templates of the beam slab and the beam bottom L-shaped hanging plate are designed into an integrated template supporting structure form, and an integrated concrete pouring method is adopted, the following problems are presented: (1) A sealing template is required to be arranged at the upper part of a concrete horizontal plate of the pre-cast beam bottom L-shaped hanging plate so as to ensure that the concrete cannot overflow at the position of the beam bottom L-shaped hanging plate in the concrete pouring process; however, the sealing template makes the vibration of the concrete at the horizontal plate of the beam bottom L-shaped hanging plate not normally performed; (2) In the concrete pouring process, as the pouring template of the vertical plate of the beam bottom L-shaped hanging plate is slender and vertically arranged, the top end of the internal space of the vertical template is communicated with the large-area beam plate space, and in the concrete pouring process, a large impact force is generated on the templates on the two sides of the vertical plate of the beam bottom L-shaped hanging plate, so that the expansion phenomenon is easy to occur; (3) Because the pre-poured beam bottom L-shaped hanging plate and the pre-poured upper beam are in a C-shaped shape, how to construct a stable template supporting structure in the C-shaped groove and how to stably support the template at the upper end in the C-shaped opening and stably transfer supporting force to the full-hall supporting frame becomes a problem to be solved on site.
