Problems solved by technology

However, setting a high-altitude assembly tire frame platform under the reticulated shell will result in time-consuming, labor-intensive, laborious, and affect the construction period
If the reticulated shell needs to cross the complex working conditions of the non-stop running ground belt conveyor in the large-span space, then the construction method of setting a high-altitude assembly tire frame platform under the reticulated shell is even more useless
[0003] Therefore, there are above-mentioned inconveniences and problems in the arrangement of the high-altitude assembly tire frame platform under the known reticulated shell.

Embodiment 1

[0027] Baosteel Ironworks Phase I and Phase II Mixing Yard BA, BB and Auxiliary Yard OA, OB Closed Renovation Project. The project address is located in the raw material yard area of ​​the third phase of Baosteel Co., Ltd. ironworks. The project structure is a space reticulated shell structure. The B-type closed stockyards of the BA and BB mixing yards of the project adopt three-core cylindrical reticulated shells with a span of 114.8 m, length 640m, height 51.5m, grid size 4.2m, reticulated shell thickness 3.75m, after considering the thickness of external purlins, the total thickness is about 4.25m. Adopt the form of lower chord support, according to the actual conditions provided by the site, the grid installation adopts the construction method of "cumulative assembly of the grid, and the gradual sliding of the tire frame", and erect the grid tire frame on the 1-3 / A-B axis of the mixing yard. Assembling platform, grid tire frame assembly platform is inside the A-B axis, the...

Embodiment 2

[0033] Except that the concrete column 1 is a post-installed steel embedded part, the others are the same as the embodiment 1.

[0034]The present invention has substantive features and significant technical progress. The double-rail sliding support structure of the large-span network frame assembly tire frame platform of the present invention is composed of the bottom support rail and the side support rail, forming the entire tire frame platform sliding system. , can realize the smooth sliding of the tire frame reticulated shell, improve the efficiency of sliding work, and ensure the progress requirements of the project.

Abstract

Provided are double-track slip support structures for a large-span net rack assembly bed-jig platform. Two sides of a net-rack span are correspondingly equipped with the double-track slip support structures. Each double-track slip support structure comprises a lateral slip steel rail system and a vertical slip steel rail system and is characterized in that each lateral slip steel rail system comprises multiple concrete columns (1), lateral slip steel rail blocking beams (3) and a lateral slip steel rail (5); the vertical slip steel rail system comprises a bed-jig spherical-hinge support bracket (8) and a vertical slip steel rail (12), wherein the bed-jig spherical-hinge support bracket and the lateral slip steel rail (5) are correspondingly arranged; and a bed-jig spherical-hinge support (7) is accommodated in the upper center of the bed-jig spherical-hinge support bracket. Each double-track slip support structure comprises the lateral slip steel rail system and the vertical slip steelrail system. A device is simple in structure and convenient in manufacture. Each lateral slip steel rail system and each vertical slip steel rail system are stable in structures. Therefore, the net-rack bed-jig platform smoothly and stably slips so that the advantage of improving slip engineering efficiency is acquired.

Description

technical field [0001] The invention relates to a support structure, in particular to a double-track sliding support structure of a large-span network frame assembly tire frame platform. Background technique [0002] With the continuous strengthening of national environmental protection measures, open-air raw material storage yards in metallurgy, coal, and electric power industries will gradually be closed in the form of grid greenhouses to reduce raw material loss and dust. Most of the open-air raw material storage yards have large spans and long lengths, and there are large-scale reclaiming equipment inside. Therefore, grid greenhouses need to be built high and the spans are getting larger and larger. This makes the installation of the reticulated shell structure more and more dangerous. In order to ensure the safety of the workers who install the reticulated shell structure at high altitude, it is generally necessary to set up a high-altitude assembly tire frame platform ...
