Description

Construction platform without external frame for prefabricated buildings

technical field

The utility model relates to a scaffold, in particular to a construction platform for a prefabricated assembled building.

Background technique

At present, there are potential safety hazards in the prefabricated structure hoisting construction. In actual projects, most of the border protection adopts the traditional cast-in-place protection method, that is, multi-layer full-paved scaffolding, and the high-rise adopts the form of cantilevered frames. Traditional scaffolding It takes a long time to set up and requires a lot of labor. In addition, the setting of the cantilever requires holes to be left on the prefabricated components and scissors to be installed, thereby destroying the integrity and leaving hidden dangers of water seepage, and a series of disadvantages such as inconvenient disassembly also caused the extension of the construction period.

Contents of the invention

The utility model aims at solving the defects of the prior art, and provides a construction platform without an outer frame of a prefabricated assembly building. The utility model provides an operation platform for the installation of the outer wall panels, and protects the borders to ensure the safety and construction efficiency of high-altitude operations.

In order to solve the above technical problems, a construction platform without an outer frame of a prefabricated building, the construction platform includes

A pair of triangular support frames fixed on the prefabricated exterior wall panels;

Platform frame, including the channel steel around as the main beam, the angle steel as the secondary beam, and the main beam and the triangle support frame are welded and connected;

Wooden springboards, above the secondary beams are covered with wooden springboards, and the wooden springboards are bound with iron wires to the secondary beams.

The construction platform without outer frame of a prefabricated building according to claim 1, characterized in that, the enclosure railings of the construction platform are finished railings, the surrounding frames are steel pipes, and there is a steel pipe horizontally at a distance of 800mm from the top and the bottom. The rod is connected with the upright.

In the prefabricated prefabricated building construction platform without an outer frame, the outer facade of the enclosure railings is enclosed by steel wire mesh.

In the construction platform without an outer frame of the prefabricated assembly building, the triangular support frame is fixed on the prefabricated outer wall board by using pull bolts.

The utility model provides an operation platform for the installation of the outer wall panels, and encloses the edges to ensure the safety of operations at high places. Compared with the traditional external scaffolding, the economic cost is saved. The entire high-rise building only needs two floors of operating platforms, which can be used alternately and repeatedly. The disassembly and disassembly of the operating platform is very convenient, and the construction efficiency is greatly improved.

Description of drawings

Below, the utility model will be further described in conjunction with the accompanying drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Please see Fig. 1, the construction platform without outer frame of a kind of prefabricated assembly type building of the present invention is mainly made up of three parts of platform frame, triangular support frame 2, enclosure railing 3. The platform slab frame is made of Q235B steel. The surrounding main beam 1 is 6.5# channel steel, and the secondary beam 4 is L40*4 angle steel with a distance of 400mm. The wooden springboard 5 is fully paved above the secondary beam, and the wooden springboard 5 is tied to the secondary beam with iron wire.

Each platform is provided with two triangular support frames supported by L70*5 angle steel. The support and the main beam of the platform can be fully welded. Two M22 bolts 6 are installed on each triangular support frame. One end of the bolt is welded to the support, and the other end passes through. After prefabricating the reserved holes on the exterior wall panels, tighten the nuts to fix the brackets on the prefabricated exterior wall panels.

The fence railing adopts finished railings. Each railing is 1800mm high and 660mm wide. The surrounding frame is φ28*2 steel pipes. There is a φ28*2.5 steel pipe horizontal bar connected to the vertical bar at a distance of 800mm from the top and bottom, and the railing plane is surrounded by steel wire mesh. Protection, steel wire mesh pitch 50*50, steel wire diameter φ3.
