Description

An operating platform for installing lattice columns

technical field

The utility model relates to an operating platform for buildings, in particular to an operating platform for installing lattice columns during the construction process of a high-rise building transfer layer Bailey frame platform, and belongs to the technical field of building construction.

Background technique

High-rise buildings often need to build transfer floor beret platforms due to structural changes between floors.

According to the retrieval, Chinese utility model patents with application numbers 201010135856.1 and 201410337666.6 disclose a construction method for the transfer floor of a high-rise building beam structure and a construction method for a Bailey beam suspension formwork support system. In view of the above-mentioned existing technologies, there are shortcomings such as the need to build a full hall support frame, which makes it difficult to ensure reliable support of each floor, affects the construction period of the transfer floor, and the stability of the load-bearing platform suspended by the boom is not good.

In order to overcome the above-mentioned shortcomings in the prior art, the applicant proposes a construction method for a high-rise building transition story Bailey frame platform supported by a sectioned structure lattice column. This method does not need to set up a full hall support frame, the load-bearing shape is ideal, and it is easy to ensure the construction period of the transfer floor without being limited by the location of the transfer floor; and it is easy to implement, and the Bailey frame platform formed by the support is stable and reliable, which can ensure quality and construction. Safety.

Contents of the invention

The purpose of this utility model is: provide a kind of operation platform that can conveniently and quickly construct lattice column support and install segmental structure lattice column, thereby realize the construction of the high-rise building conversion layer Bailey frame platform supported by constructing lattice column method to create better conditions.

In order to achieve the above-mentioned purpose, the operating platform for installing lattice columns of the present invention includes a "concave"-shaped countertop enclosure made of solidly connected profiles. The inner profile of the opening of the enclosure matches the outer profile of the lattice column to be installed. The upper surface of the surrounding frame is covered with a fixed metal plate, and the outer periphery of the upper surface is welded with a fixed guardrail.

When in use, clamp and fix the operating platform of the present utility model outside the installed base lattice column section, and after the current lattice column section is installed and fixed in place, move the operating platform to the top to proceed The installation of a section of lattice column; this cycle, until the top of the lattice column reaches the required elevation; very convenient and safe.

A further improvement of the utility model is that two cantilever beams extending into the opening toward the opening are fixedly connected to the outer side of one end of the surrounding frame. When in use, the cantilever beam is inserted into the installed lattice column section, so that the operating platform is more stable and plays a role of safety guarantee.

A further improvement of the utility model is that horizontal ear plates with holes are respectively welded and fixed on both sides of the opening end of the surrounding frame, and vertical ear plates with holes are welded and fixed on the outer periphery at intervals. In this way, with the help of the lug plate, it is more convenient whether it is lifting the operating platform or fixing it with the lattice column section.

detailed description

Embodiment one

The transfer layer of the high-rise building in this embodiment is located above the ninth floor. During construction, it is first necessary to pass pre-buried at the positions below the girders of the transfer layer corresponding to the two sides of the lattice column foundation 1-2 connected with the building foundation 1-1. Anchor bolts 1-3 are installed with lattice columns 1 distributed at intervals. The lattice column 1 of this embodiment is shown in Fig. 1, and the standard tower sections 1-4 of the tower crane are used to splice them section by section from bottom to top.

During splicing and installation, the tool-type operating platform 2 shown in Fig. 2, Fig. 3 and Fig. 4 is adopted. The platform 2 has a "concave"-shaped surrounding frame 2-1 welded by channel steel profiles, and the upper surface of the surrounding frame 2-1 is Covering and fixing patterned steel plate 2-2, the inner profile of the opening matches the outer profile of the standard tower section, and the outer periphery of the upper surface is welded with a guardrail 2-3 made of fixed steel pipes; The cantilever beam 2-4 extending into the opening in the direction, the two sides of the opening end are respectively welded and fixed with horizontal ear plates 2-5 with holes, and the outer circumference is welded and fixed with vertical ear plates 2-6 with holes; Install the operation platform 2 on the outside of the installed standard tower section, lift it with the help of lug plates and connect it with the installed standard tower section, and insert the cantilever beam into the installed standard tower section to play a role of safety protection; when the current tower After the section is installed and fixed in place, remove the fasteners at the lug plate, move the operating platform 2 to the top, and then install the last lattice column section. This cycle is repeated until the top of the lattice column reaches the desired level that is flush with the floor to be converted.

Practice has proved that the tool-type operating platform of this embodiment is flexible and convenient to use, safe and reliable. It can not only be used step by step when installing the same lattice column, but also can be used alternately between lattice columns, thereby significantly reducing construction materials. It saves the stacking space and helps to shorten the construction time.
