Description

Construction platform suspended from concrete construction columns of building exterior wall

technical field

The utility model relates to a building construction platform, in particular to a construction platform for hanging a concrete structural column of an outer wall of a building.

Background technique

Reinforced concrete frame structure is a widely used structural form in civil buildings. At present, external scaffolding is generally required for the construction of external walls between frames of this structure. External scaffolding has complex structures and large material consumption. Construction High cost defects.

Contents of the invention

The technical task of the utility model is to provide a construction platform with a simple structure and good safety for the suspension of the concrete structural column of the building exterior wall in view of the shortcomings of the above current situation.

The technical solution adopted by the utility model to solve its technical problems is: the concrete structure column of the building exterior wall of the utility model hangs the construction platform. , the lower supporting rods are set at the lower parts of both ends of the frame structure, the upper reinforcing inclined rods connect the uprights and the upper supporting rods, the lower reinforcing rods connect the uprights and the lower supporting rods; the upper supporting rods are provided with pre-tightening screws and cross pins; On the top connecting cross bar, the platform board is arranged on the bottom and/or middle connecting cross bar, and the protective net is arranged on the outer facade and two sides of the frame structure.

The upright column, the connecting cross bar, the upper supporting rod and the lower supporting rod are all made of square steel pipes.

The diameter of the tightening screw is not less than 20mm.

The protective net is dense mesh.

Compared with the prior art, the concrete structure column suspension construction platform of the building exterior wall of the utility model has the following characteristics: the utility model has achieved a scientific design by setting up columns and connecting cross bars, and is simple in structure, easy to move, and can be used many times Turnaround use works well. In the case of no external scaffolding, it provides an operating space for the construction of the concrete structural column of the external wall, ensuring safe construction.

detailed description

With reference to the accompanying drawings of the description, the construction platform suspended by the concrete structural column of the building exterior wall is described in detail below.

The construction platform is suspended by the concrete construction column of the building exterior wall of the utility model. The structure includes a frame structure composed of a column 1 connected with a connecting cross bar 2. Upper support rods 3 are arranged at the upper parts of both ends of the frame structure, and lower supports are arranged at the lower parts of both ends of the frame structure. Rod 4, the upper reinforcing oblique rod 5 connects the column 1 and the upper support rod 3, the lower reinforcing rod 11 connects the column 1 and the lower support rod 4; the upper support rod 3 has a threaded hole and a pin hole respectively provided with a top tightening screw 6 , cross bolt 7. The hoisting ring 8 is arranged on the top connecting crossbar 2, the platform plate 10 is arranged on the bottom and/or middle connecting crossbar 2, and the protective net 9 is arranged on the facade and two sides of the frame structure.

Described column 1, connecting cross bar 2, upper support bar 3, lower support bar 4 all adopt square steel pipe to make.

The diameter of the tightening screw 6 is not less than 20mm.

The protective net 9 is a dense mesh.

The platform board 10 is a 50mm thick wood board.

The cross pin and the hoisting ring are made of HPB300 steel bars with a diameter of 20 mm.

During the construction of the utility model, the steel wire rope is passed through the hoisting ring 8, and the construction platform is hoisted to the installation position by a tower crane. The lower supporting rod 4 is placed on the floor, and screwed into the top tightening screw 6 on the upper supporting rod 3, Block the bottom of the beam, then insert the cross pin 7 into the pin hole on the upper support rod 3, block the inside of the beam, and prevent the platform from tilting out. After the platform is installed, according to the different heights of the structural column construction, the platform slab 10 is laid at the bottom and/or middle of the platform. The platform slab 10 needs to be bound firmly with the connecting cross bar 2 with iron wire to prevent slippage. Hang protective net 9 on facade and two sides at last.

When it needs to be dismantled after the construction is completed, first remove the sundries on the platform, check whether the platform slab 10 is firmly fixed, then fasten the steel wire rope of the tower crane to the hoisting ring 8 to keep the steel wire rope at a relatively short slack length, and then unscrew the top tightening screw 6 and pull it out. Push out the cross pin 7, and finally cooperate with the tower crane to push out the whole platform horizontally by manpower, and hang it to the next installation position by the tower crane. .

The utility model provides a construction platform and a protective device for workers to install and dismantle structural column templates in the outer wall without external scaffolding.
