Two edges positioned at the bottom in the figure 4 are longer, so that the two edges can be conveniently fixed on the bottom rib 1 through the binding wires. Usually one stirrup 2 is placed at each of the four corner positions of one of the mould boxes 7.

Referring to fig. 1 to 4, based on the same technical concept as the reinforced structure of the formwork, the present invention further provides a construction method of a concrete structure, which may be a construction method of a basement roof, the method mainly comprising the following steps: arranging and paying off a die box 7 → positioning and binding C6 (the diameter of the HRB400 steel bar is 6 mm) double U-shaped horseshoe-shaped stirrup → installing the die box 7 → binding C12 ribbing 3 → reinforcing and pressing the self-locking nylon cable tie and a bottom rib 1 → tying a bottom rib 1 and a square log rib 6 → binding gluten 8 and pouring concrete.

In the construction method of a concrete structure provided by this embodiment, the stirrup 2 is fixed on the bottom rib 1 through the tie wire, and the press rib 3 and the bottom rib 1 are fixedly connected through the first nylon tie 4, so that the mold box 7 can be prevented from floating or inclining when concrete is poured; the first nylon cable tie 4 has a self-locking function, and the pressing rib and the bottom rib are conveniently fixed; the first nylon cable tie 4 can not rust in the later period, and the price is cheaper than that of an iron wire.

The concrete construction steps of the construction method of the basement top plate refer to the following steps:

1. mould box 7 arrangement paying-off

After the basement top plate template is laid, arranging, positioning and paying off of the mold boxes 7 are carried out on the surface of the template according to the construction blueprint.

2. C6 double U shape stirrup 2 (stirrup 2 can also be called stool or stool tendon) positioning binding

C6 reinforcing steel bars are adopted to manufacture C6 double U-shaped horse stool ribs, and 4 horse stool ribs are bound at the lower part of each 600X 300 (length, width and height) mold box 7; the split heads are firmly bound with the top plate bottom rib 1 through binding wires; wherein, the bottom rib 1 is paved on the upper surface of the template, and the square wood secondary ridge 6 is supported on the lower surface of the template.

3. Mounting of the mould box 7

The hollow mould boxes 7 are arranged according to the positioning lines, and the two U-shaped split heads at the bottom are prevented from loosening in the arrangement process.

4. C12 ribbing 3 banding

The hollow mould boxes 7 are reinforced by C12 deformed steel bars, and each mould box 7 is reinforced by a C12 deformed steel bar in two directions.

5. Self-locking nylon cable tie reinforcement

The self-locking nylon cable ties are oppositely pulled to reinforce the pressing ribs 3 and the bottom ribs 1, and one self-locking nylon cable tie (namely the first nylon cable tie) is tied at each of the four side positions of the die box 7 by the four-way pressing ribs 3 of each 600 x 300 die box 7; the tensile strength of the ribbon satisfies 0.7KN tensile force.

After the self-locking nylon cable tie is reinforced, whether each hollow mold box 7 is positioned and placed neatly and accurately is checked, and the position deviation is not larger than 5 mm. And the deviated hollow mold box 7 is subjected to positioning correction, so that the sizes of a web plate and a flange of the hollow mold box 7 meet the design requirements.

6. Bottom rib 1 and formwork support tie

In order to ensure that the mold box 7 does not float upwards integrally in the concrete pouring process, after the mold box 7 is fixed on the base of the bottom rib 1 by the aid of the pressing rib 3 and the binding belt, the bottom rib 1 and the secondary edges of the plate mold are bound and connected by the binding belt to form a whole, and accordingly the anti-floating effect is achieved. The concrete construction method comprises the following steps:

the bottom rib 1 and the secondary edge binding connection point of the plate template are horizontally spaced by the binding belt and are not more than 1.3 m (about 2 mold boxes 7 spaced) distributed with points and pulled.

7. Gluten 8 binding and concrete pouring

The gluten 8 can be connected and fixed with each other through iron wires.

Before concrete pouring, whether the position of the mold box 7 is accurate and whether the mold box 7 is damaged should be checked again to ensure that the upper mold box 7 and the lower mold box 7 are aligned and fixed and cannot be misplaced. The damaged mould box 7 should be repaired or plugged by effective measures to prevent the concrete from leaking into the mould box to reduce the hollow rate of the slab. When concrete is poured, the vibrator is prevented from directly contacting the die box 7 to cause damage to the die box 7.

Because the width and the surface layer of the hollow floor rib beam are smaller, in order to ensure the concrete pouring quality, strict requirements are imposed on concrete aggregate, and the maximum particle size of the crushed stone should not exceed 25. The slump of the concrete is not less than 160 mm.

The direct placement of construction implements and materials on the form 7 is prohibited and the construction operator must not step directly on the form 7. The hoisting weight in construction should drop on the backing plate, should set up the backing plate and support the backing plate on the steel reinforcement skeleton erected at the support of the commercial concrete conveying pipe.

The concrete pump emptying should pay attention to the distance between the discharge hole and the hollow mold box 7, so that the hollow mold box 7 is prevented from being damaged by impact caused by concrete. The flow of the concrete to be pumped should be controlled and the gear of the delivery pump should be reduced to reduce the impact force on the hollow mould box 7.

The concrete pouring adopts a 'secondary pouring one-step forming method', namely 500-plate thick layered pouring, 1/2 rib height of primary pouring, and secondary concrete forming is carried out before the initial setting of the concrete. The concrete vibrating rod should be vibrated to protect the hollow mold box 7, the reinforcing steel bars and the self-locking nylon cable ties, so that the reinforcing measures are prevented from being damaged during vibration.

In summary, according to the reinforced structure of the mold box provided by the utility model, the stirrup 2 is fixed on the bottom rib 1 through the binding wire, and the pressing rib 3 and the bottom rib 1 are fixedly connected through the first nylon binding belt 4, so that the mold box 7 can be prevented from floating or inclining when concrete is poured; the first nylon cable tie 4 and the cable tie have a self-locking function, so that the pressing rib and the bottom rib can be conveniently fixed; the first nylon cable tie 4 can not rust in the later period, and the price is cheaper than that of an iron wire.

The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the present invention.
