Embodiment Construction

[0027] Such as figure 1 , figure 2 Shown:

[0028] The steel-reinforced concrete conjoined transfer layer suspended formwork support system consists of two parts:

[0029] 1) Steel-reinforced concrete conjoined transfer beam 3 (consisting of steel main beam 1 and concrete) adopts self-supporting formwork (consisting of steel main beam 1, steel tie rod 5, channel steel 9 and straight thread sleeve 10), the concrete, The weight of steel bar and formwork and construction live load are transferred to steel girder 1 through multiple pairs of evenly distributed steel tie rods 5;

[0030] 2) The concrete floor 4 of the transfer floor adopts the conventional floor formwork support 6, and the steel structure refuge floor 7 suspended by several steel suspenders 2 from the lower part of the transfer floor bears various loads of the floor formwork support 6.

[0031] 1. A conjoined load-bearing structure is composed of a steel-reinforced concrete conjoined transfer layer and a suspend...

Abstract

The invention relates to a construction method of a suspension type template support in high-position conjoined structure. The construction method comprises the working procedures of installing a tank type steel hanging post, installing steel beams and profiled steel plates, welding shearing-resistance studs, bonding reinforcing bar nets and pouring floor bearing plate concrete to accomplish the construction of the suspension type template support in the high-position conjoined structure. The invention overcomes the defects of large use level of support materials, long mounting and demounting construction period, high reinforcing expense, high construction cost, large dead weight, large construction difficulty and the like existing in the traditional method of bearing full supports and erecting high-altitude heavy operation platforms. The invention sufficiently utilizes the bearing capacity of a conversion-floor steel girder so that the combined floorslab in the conversion floor is used as an operation platform for erecting the template support in the construction stage and is used as a permanent refuge floor of an ultrahigh-rise building in the usage stage, thereby ensuring the safety of high-altitude work, saving the construction expense and increasing the use area. The steel girders are used as stiff reinforcing bars in the work of steel skeleton concrete conjoined structure to together bear the structural dead weight and the construction load which are gradually increased in each layer of the upper part of the steel girder.

Description

technical field [0001] The invention relates to a high-level conjoined structure in a high-rise building, in particular to a construction method for a suspended formwork support of a high-level conjoined structure. Background technique [0002] There are more and more buildings with aerial corridors or conjoined structures between the twin towers of high-rise commercial and residential buildings and office buildings. Whether the construction technology of the formwork support system for the transfer floor formwork support system of the high-altitude conjoined concrete structure of these buildings is reasonable will directly affect the project. The key to the construction of the transfer floor structure is to select the correct formwork support construction technology. Before the present invention, formwork support construction technology has: [0003] The first is to adopt the traditional load-bearing full hall support frame. After measures are taken to reinforce the roof ...
