Abstract
The utility model relates to a formwork support diagonal bracing system, in particular to the formwork support diagonal bracing system for construction of cast-in-situ concrete large cross-sectional beams. The formwork support diagonal bracing system comprises a fine stone bottom concrete column. A jacking steel tube which is fixed with the fine stone bottom concrete column is arranged on the upper portion of the fine stone bottom concrete column. A steel channel beam which is fixed with the jacking steel tube is arranged on the upper portion of the jacking steel tube. An inclined strut which is obliquely disposed is arranged between the steel channel beam and the fine stone bottom concrete column. The formwork support diagonal bracing system for construction of the cast-in-situ concrete large cross-sectional beams is compact in structure, enables the construction cycle to be shortened, reduces cost input, and is convenient to operate, strong in load bearing capacity and high in stability.
Description
Technical field
The utility model patent relates to a kind of support for shuttering shoring, relates in particular to the support for shuttering shoring of a kind of Cast-in-place concrete heavy in section beam construction.
Background technology
The form that adds large chassis (large tracts of land podium) in the modern building design under large quantities of high-rise high buildings is very common, because of large chassis podium architectural design purposes generally needs large space, its vertical load-bearing concrete wall was few as far as possible when this just required structure design, but the top high building is dwelling house or office design, do not need large space, and high-level structure must have certain vertical load-bearing concrete wall, so just cause top to have a collection of concrete wall directly to drop on the basis, must conversion layer structure be set on podium top or certain layer, the concrete wall on top is dropped on the conversion crossbeam.Press Structural Design Requirement, this conversion crossbeam general section is all bigger, and depth of section is generally more than 2000mm, and what have surpasses 3000mm, and the beam section width is bigger, and great majority are more than the 500mm.The working load of the cast-in-place beam in heavy in section can be very big like this, but the designer often not will consider this working load, this problem of will taking measures during construction to solve or evade during design of building structures.Mainly contain following these schemes so far: 1, commonsense method formwork, adopt the method for placement layer by layer off-loading, crossbeam watered at twice by horizontal direction smash, reach to water again after certain intensity and smash concrete for the second time Deng concrete strength for the first time, can utilize the intensity of concrete for the first time like this, alleviate load, the method must the designer be calculated the back agreement; 2, by overweight template common steel tube or shaped steel formwork, working load is delivered to lower floor by steel pipe or shaped steel, is security consideration, below which floor must establish support layer by layer, till load passed to the building foundation, like this construction input can be very big, and construction is inconvenient; 3, utilize frame column to set up the horizontal supporting member of steel work temporarily, the working load of crossbeam is delivered to the frame column of building by the steel work layer, can avoid load to pass to following which floor flooring like this, but the steel work amount that drops into can be very big, and could construct next step after waiting frame column to reach design strength, can prolong the duration, on frame column, also will add some brackets and embedded part are set, can influence original structure to a certain extent.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, a kind of load-bearing support for shuttering of processing simple, economical and practical, non-structure risk, pollution-free, easy accessibility is provided, and can mixes the support for shuttering shoring of the Cast-in-place concrete heavy in section beam construction of use with common support for shuttering.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The support for shuttering shoring of a kind of Cast-in-place concrete heavy in section beam construction, comprise concrete post at the bottom of the microlith, the top of concrete post is provided with the jacking steel pipe that fixes with it at the bottom of the described microlith, the top of described jacking steel pipe is provided with the steel channel beam that fixes with it, and the concrete intercolumniation is provided with the diagonal brace that diagonally distributes at the bottom of described steel channel beam and the microlith.
As preferably, the upper end of described jacking steel pipe, middle-end and lower end are respectively equipped with the thick pillar steel pipe, the middle-end of described diagonal brace is provided with short steel column, be provided with the diagonal brace steel pipe between described diagonal brace and jacking steel pipe, the thick pillar steel pipe crimping mutually of one end of described diagonal brace steel pipe and upper end, the top crimping mutually of the other end of described diagonal brace steel pipe and short steel column.
As preferably, fix by the diagonal brace bearing between described diagonal brace and steel channel beam, the bottom of described diagonal brace is provided with the diagonal brace base plate that fixes with concrete post at the bottom of the microlith.
Therefore, the support for shuttering shoring of Cast-in-place concrete of the present utility model heavy in section beam construction, compact conformation, the reduction of erection time, reduce the cost input simultaneously, easy to operate, load is strong, and stability is high.
