In order to realize the technical purpose, the utility model adopts the following scheme: the supporting structure for the formwork of the overhanging cornice on the steel bar net rack comprises a bracket, a cross beam, a supporting hook, a supporting plate and a limiting clamp; the both sides of support are fixed with the support hook respectively, and the top of support is connected with the crossbeam, and the crossbeam card is in spacing clamp, and spacing clamp is fixed in the backup pad.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a support is placed in the reinforcing bar rack, utilizes the support hook to support the reinforcing bar rack, and the crossbeam card is at flitch backup pad lower surface, and the backup pad is scaffold frame vertical support's holding surface, and simple to operate has improved structural stability, guarantees the supporting effect, reduction of erection time to this structure simple manufacture, construction convenience, it is with low costs.

Furthermore, two ends of the cross beam are respectively connected with a support, the supports are of arc-shaped frame structures, and the support hooks are fixed on the middle upper portion of the supports.

Furthermore, a joist is placed on the joist hook at the same side, and the joist supports the steel bar net rack.

Furthermore, the limiting clamp is of a C-shaped groove structure, and an opening of the C-shaped groove is arranged downwards.

Detailed Description

In order to fully understand the objects, features and functions of the present invention, the following detailed description of the present invention is given, but the present invention is not limited thereto.

As shown in fig. 1 and 2, the utility model provides a pair of a bearing structure for hang cornice formwork on reinforcing bar rack comprises support 1, crossbeam 2, support hook 3, backup pad 6 and stopper 4. The support 1 is an inverted U-shaped structure, the upper parts of legs at two sides of the support 1 are respectively welded with an arc-shaped supporting hook 3 with an upward opening, and the arc-shaped supporting hook 3 supports upper-layer steel bars of a steel bar net rack. The upper end middle part fixedly connected with crossbeam 2 of support 1, preferred, a support 1 is fixed respectively at crossbeam 2 both ends, constitutes a stirrup bearing structure. Crossbeam 2 wears to adorn in stopper 4, and stopper 4 is C type groove that the opening is down, and C type groove is fixed on the lower surface of backup pad 6, prevents that backup pad 6 from taking place to control the skew.

The specific operation method of site construction comprises the following steps:

the method comprises the steps that HPB300 phi 12-phi 18 steel bars are used for bending into an arc shape, the upper ends of two arc-shaped legs are welded to form a support 1, the top of the support 1 is firmly welded with one end of an HPB335 phi 12-phi 18 steel bar with a proper length, the other end of the HPB335 phi 12-phi 18 steel bar is welded with the top of the other support 1, and the top steel bar between the two supports 1 serves as a cross beam 2 of a supporting structure.

According to the thickness of the reinforced concrete structure plate, a reinforced hook is welded on the outer side of each pair of supports 1 at a proper height position away from the bottom as a supporting hook 3, so that the novel stirrup supporting structure is formed by the supports 1, the cross beam 2 and the supporting hook 3.

The method comprises the steps of selecting a batten with the cross-sectional dimension of 100mm multiplied by 100mm as a supporting plate 6, embedding a pair of bolts at the bottom surfaces of two ends of the batten respectively, enabling the bolts to be exposed out of the bottom surfaces of the batten at a certain height, enabling the end portions of the bolts arranged in pairs to form a C-shaped clamping groove with a downward opening, using the C-shaped clamping groove as a limiting block, sliding the cross beam 2 into the C-shaped clamping groove from the end portions, and preventing the batten from sliding in the left and right directions relative to the upper portion of the cross beam 2.

After the structure board reinforcement bottom reinforcing bar, according to hanging relevant factors such as eave plate thickness, support distance, height, two are a pair of novel stirrup bearing structure of arranging, then select the suitable reinforcing bar of diameter and length to place on the joist 3 as joist 5, and the structure board reinforcing bar is binded, places the structure board top layer reinforcing bar on joist 5, and the structure board top layer reinforcing bar of another direction of ligature is through support 1,

joist

3, 5 bearing structure board reinforcing bar rack of joist. And finally, placing the bottom of the vertical supporting rod of the supporting frame system of the overhanging eave board on the upper part of the top surface of the batten, and then carrying out bracket installation, as shown in figure 3.

The utility model discloses with conventional for formwork bearing structure contrast, have following advantage: (1) The eaves plate and the lower concrete structural plate do not need to be divided into two parts for construction, the construction speed is high, and the consumed construction period is short; (2) the manufacturing is simple, and the construction is convenient; (3) the leveling of the supporting surface is easy to control, and the construction effect is good; (4) the process is less to implement and the efficiency is high; (5) the system and installation period is short, and the installation speed is high; (6) the loss is small, and the construction cost is low; (7) the steel bar can also be used as a horse stool bar, and the application range is wide; (8) the stability is good, the supporting effect is good, and no potential safety hazard exists.
