Description

Formwork support system for integral casting of beam plate and L-shaped hanging plate at the bottom of the beam

Technical field

The invention relates to a formwork support system for beam plate pouring in a cast-in-place concrete factory building, and in particular to a formwork support system for integrally pouring beam plates and L-shaped hanging plates at the bottom of the beam.

Background technique

For cast-in-place large-span concrete frame structure factories with high floor heights (for example, factories with a floor height of more than 6 meters and a span of more than 8 meters), the conventional construction method is: first pour the foundation floor of the completed factory building, and then On the foundation floor, a pouring formwork support frame for the upper frame beam plate is set up. On the upper part of the pouring formwork support frame, a concrete pouring formwork system for the upper frame beam and slab is constructed. After the steel bars of the beam and slab are tied, concrete is poured to form the upper concrete beam. and the overall structure of the slab; long-span factory buildings with higher storey heights are generally designed with long-span doors and windows under the outer beams around the upper concrete beam slab. Since the height of long-span doors and windows is within the range of about 3 meters, in order to reduce the load on the upper floor The load of the concrete frame beam is generally designed with an L-shaped cast-in-place concrete hanging plate between the top of the long-span door and window and the bottom of the upper frame beam. The L-shaped cast-in-place concrete hanging plate and the concrete beam on top form a C-shaped concrete whole. Structure, long-span doors and windows are installed below the L-shaped cast-in-place concrete hanging panels; this structure not only reduces the load of the upper concrete beams, saves concrete component materials, but also meets the installation requirements of factory doors and windows; in view of this common The structure of the concrete beam and the L-shaped hanging plate is adopted. The existing technology is to separately support the concrete pouring formwork of the beam plate and the concrete pouring formwork of the L-shaped hanging plate, and adopt the step-by-step pouring of the concrete beam plate and the hanging plate under the beam. To complete the construction, that is, first support the concrete pouring formwork of the upper frame beam plate and complete the concrete pouring. After the concrete strength of the upper beam plate reaches the dismantling standard, remove the pouring formwork of the upper frame beam plate and then support it a second time. The formwork of the L-shaped cast-in-place concrete hanging board, and the second pouring of the L-shaped cast-in-place concrete hanging board; when the concrete pouring of the L-shaped cast-in-place concrete hanging board is carried out, since the top of the concrete hanging board has been poured with the completed concrete beam Closed, only an outward-inclined concrete pouring funnel can be set up to realize the pouring of L-shaped cast-in-situ concrete hanging panels; this conventional construction method has the following problems: (1) Grading of beam plates and L-shaped hanging panels Formwork erection and staged pouring take a long time, which greatly extends the construction time; (2) The concrete pouring of the beam plate and L-shaped hanging plate is staged, forming a joint gap at the connection between the two, which is prone to leakage water phenomenon; (3) After the L-shaped concrete siding is poured, the concrete bumps formed by the pouring funnel need to be removed, which is time-consuming and material-intensive, and also affects the appearance of the factory facade; if The concrete pouring formwork for the beam plate and the L-shaped hanging plate at the bottom of the beam is designed as an integrated formwork support structure, and the integral concrete pouring method is used. There are also the following problems: (1) The concrete level of the pre-poured L-shaped hanging plate at the bottom of the beam A sealing formwork needs to be set up on the upper part of the slab to ensure that concrete will not overflow here during the concrete pouring process of the L-shaped hanging plate at the bottom of the beam; but the sealing formwork will prevent the concrete from the horizontal plate of the L-shaped hanging plate at the bottom of the beam. Vibration cannot proceed normally; (2) During concrete pouring, since the pouring formwork of the vertical plate of the L-shaped hanging plate at the bottom of the beam is slender and set vertically, the top of the internal space of the vertical formwork is in contact with the large-area beam plate. The spaces are connected together. During the concrete pouring process, a large impact force will be exerted on the formwork on both sides of the vertical plate of the L-shaped hanging plate at the bottom of the beam, which can easily lead to the phenomenon of expansion; (3) Due to the pre-poured L-shaped hanging plate at the bottom of the beam, The hanging board and the pre-cast upper beam are in a C-shaped shape. How to build a stable formwork support structure in the C-shaped groove, and how to firmly support the formwork at the upper end of the C-shaped opening and transfer the support force smoothly It became a difficult problem that needed to be solved on site when it was placed on the supporting frame of the whole hall.

After the integrally poured beam plate and the L-shaped hanging plate at the bottom of the beam are finally solidified, the height-adjustable top support 10 is rotated to separate the height-adjustable top support 10 from the horizontal cantilever beam steel pipe 11, and the supporting steel pipe column 9 in the C-shaped opening is removed. , after the left support back corrugation 14 of the left vertical formwork of the L-shaped hanging board and the left vertical formwork 15 of the L-shaped hanging board, remove the horizontal cantilever beam steel pipe 11 and the pre-cast beam bottom formwork support wooden corrugation 12 and the pre-cast beam. Bottom formwork 13; then, by rotating the top adjustable top support 27 of the vertical support pole, the top connection of the top adjustable top support 27 of the vertical support pole to the L-shaped hanging plate bottom formwork support beam 4 is released, and the L-shaped hanging plate is removed. The bottom formwork supports the cross beam 4 and its L-shaped hanging board bottom formwork longitudinally supports the wooden corrugations 5 and the L-shaped hanging board bottom formwork 6; finally, the full hall bracket 1 is dismantled, and the beam plate and the beam bottom L-shaped hanging board are constructed.
