The efficiency is low, and the installation of the eaves support system is difficult, which increases the construction difficulty and costs a lot.

Due to the tight construction period, construction factors or climate reasons, the construction period has to be shortened. The lower concrete slab and the upper cantilever cornice are poured and constructed at the same time. This requires that the support on the steel grid must be firm and stable, otherwise the overall support frame will be prone to instability. , Overturning and other quality accidents occurred. The construction method of vertically supporting and fixing the formwork on the traditional reinforced grid is mainly to lay steel plates on the reinforced grid, level the steel plates through welding backing plates to ensure that they are on the horizontal plane, install vertical steel pipe supports on the steel plates, and pour concrete on the bottom slab Cut off the steel pipe when finished.

This construction method has limitations: (1) It is inconvenient to lift and install the steel plate, and it is difficult to fix; (2) It is difficult to control the flat leveling of the steel plate, with low precision and poor construction effect; (3) It is necessary to remove the steel pipe, steel plate and backing plate in the later stage Large investment and high construction cost; (4) Many implementation procedures, low efficiency and long construction period.

Detailed ways

In order to fully understand the purpose, features and effects of the utility model, the utility model will be described in detail through the following specific implementation methods, but the utility model is not limited thereto.

As shown in Figures 1 and 2, the utility model provides a support structure for supporting the formwork of the cantilevered eaves on the reinforced grid, which consists of a bracket 1, a beam 2, a hook 3, a support plate 6 and a limit block 4 composition. The support 1 is an inverted U-shaped structure, and the upper parts of the legs on both sides of the support 1 are respectively welded with an arc-shaped support hook 3 with an opening facing upwards, and the arc-shaped support hook 3 supports the upper steel bars of the steel bar grid. The middle part of the upper end of the bracket 1 is fixedly connected with a beam 2, and preferably, a bracket 1 is respectively fixed at both ends of the beam 2 to form a stirrup support structure. The crossbeam 2 is installed in the limit block 4, and the limit block 4 is a C-shaped groove with the opening facing downward. The C-shaped groove is fixed on the lower surface of the support plate 6 to prevent the support plate 6 from shifting left and right.

The specific operation method of on-site construction:

Use HPB300φ12~φ18 steel bars to bend into an arc shape, and weld the upper ends of the two arc-shaped legs to form a bracket 1. The top of the bracket 1 is welded firmly with one end of a HPB335φ12~φ18 steel bar of appropriate length, and the other end is connected to the top of another bracket 1. Welding, the top reinforcement between the two brackets 1 serves as the beam 2 of the supporting structure.

According to the thickness of the reinforced concrete structural slab, a steel bar crotch is welded on the outside of each pair of supports 1 at a suitable height from the bottom as the support hook 3, so that a novel stirrup support structure is formed by the support 1, the beam 2, and the support hook 3.

Select a wooden square with a cross-sectional size of 100mm×100mm as the support plate 6, and insert a pair of bolts at the bottom of the two ends of the wooden square. The bolts are exposed to a certain height from the bottom of the wooden square. Type draw-in groove, as stopper, crossbeam 2 is slid in the C-type draw-in groove by end, prevents that wooden side slides in crossbeam 2 top relatively left-right direction.

After the steel bars on the structural slab are bound to the bottom steel bars, according to the thickness of the cantilevered eaves, the distance between the brackets, the height and other related factors, two pairs of new stirrup support structures are arranged, and then steel bars with appropriate diameters and lengths are selected and placed on the brackets 3 as supports. Beam 5, bind the steel bars of the structural slab, place the top steel bar of the structural slab on the joist 5, bind the top steel bar of the structural slab in the other direction, and support the steel bar grid of the structural slab through the bracket 1, the bracket 3, and the joist 5. Finally, place the bottom of the vertical pole of the support frame system of the cantilevered cornice on the upper surface of the wooden square, and then the support can be installed, as shown in Figure 3.
