Technical Field

The invention relates to a novel large formwork platform system, in particular to a foldable large formwork top pouring platform bearing support.

Background

The large formwork system is a common formwork system, and is widely applied to construction of various concrete structures due to the characteristics of light weight, high rigidity, high construction speed, simplicity and convenience in construction operation and the like. In order to facilitate the binding of reinforcing steel bars, the installation of embedded parts and the pouring of concrete on site, a working platform needs to be configured at the top of the large formwork. The current large formwork top pouring platform support has the following problems:

1. the traditional top pouring platform support of the large formwork is of a fixed tripod structure manufactured by welding profile steel components, the top pouring platform can only be assembled in advance at a construction site, and the platform after the assembling process and the assembling are completed needs to occupy a large amount of fields, so that a great deal of inconvenience is brought to construction.

2. After the large formwork and the pouring platform are combined, the top platform extends outwards, so that the combined large formwork cannot be stacked in an overlapping mode, and more finished product stacking areas need to be planned. This is increasingly the conflict between the limited narrow construction plant area and the required stacking area for the forms for most projects.

3. A large amount of manpower and material resources are consumed when the traditional top pouring platform support is assembled on site, and a great deal of inconvenience is caused to site management.

4. Fixed A-frame main platform is only a fixed angle, when the slope of a pouring structural plane changes, the platform cannot be leveled along with the change of the slope of the structural plane, and an operator can only stand on an inclined working platform to operate, so that construction and site safety management are inconvenient.

Preferably, the pressure-bearing inclined rod 4 is movably connected with the lower connecting support.

The foldable top pouring platform bearing support, the platform walkway plate and the railing are assembled to form the top pouring platform together. By means of the folding functional design of the structure, the platform can be turned upwards to coincide with the plane of the railing.

The cross rod is a main girder of the walkway plate and the upright rod is a main girder of the railing. Both are standardized components. The platform walkway plate is connected with the cross rod through a mounting hole in the cross rod, and the railing enclosure is connected with the vertical rod through a mounting hole in the vertical rod. The design of the assembled components of the structure realizes the standardized prefabrication of the working platform and the railing in a factory.

The beneficial effects of the invention are as follows: 1. the foldable large formwork top pouring platform force-bearing support can be folded into a linear shape, the occupied space of transportation and storage is small, the storage and transportation space is saved, and the storage and transportation cost is reduced. 2. The mounting hole that foldable horizontal pole was reserved makes things convenient for platform adjustment installation angle, has improved site operation personnel's construction travelling comfort and security. 3. The design of assembled parts makes work platform and railing realize the standardized prefabrication of mill, 4, the maintenance of standardized product platform component and impaired subassembly change link at later stage are faster simpler, have greatly practiced thrift the time and the cost of maintaining.

In conclusion, the structure mainly solves the problem of contradiction of stacking the large formwork with the platform on a construction site, indirectly optimizes the transportation and storage management of the bearing support of the large formwork top pouring platform, improves the factory assembly degree and product quality control of the large formwork top pouring platform, reduces the total cost of the formwork, and improves the convenience and safety of site construction.
