Abstract
The utility model relates to a cross support fixing system, in particular to a cross support fixing system of cast-in-place concrete large-section beam construction. The cross support fixing system comprises a pair of fine stone bottom concrete columns which are distributed at intervals, a jacking steel pipe fixed with each fine stone bottom concrete column is arranged on the upper portion of each fine stone bottom concrete column, a channel steel beam fixed with the jacking steel pipes is arranged on the upper portion of a position between the jacking steel pipes, and a bottom horizontal tube is arranged between the fine stone bottom concrete columns. Inclined supports are arranged between the bottoms of the fine stone bottom concrete columns and the bottom of the channel steel beam, inclined support steel pipes are arranged between the jacking steel pipes and the inclined supports, and the inclined support steel pipes stretch downwards and are fixed with the bottom horizontal tube. The cross support fixing system of cast-in-place concrete large-section beam construction is compact in structure, shortens construction periods, reduces cost investment, and is convenient to operate, strong in bearing ability, and high in stability.
Description
Technical field
The utility model relates to a kind of cross support fixed system, relates in particular to the cross support fixed system 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 cross support fixed system 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 cross support fixed system of a kind of Cast-in-place concrete heavy in section beam construction, comprise concrete post at the bottom of the microlith that pair of spaced distributes, the top of concrete post is provided with the jacking steel pipe that fixes with it at the bottom of the described microlith, top between described jacking steel pipe is provided with the steel channel beam that fixes with it, the concrete intercolumniation is provided with the bar of sweeping the floor at the bottom of the described microlith, be provided with diagonal brace between the bottom of concrete post and steel channel beam at the bottom of the described microlith, be provided with the diagonal brace steel pipe between described jacking steel pipe and diagonal brace, described diagonal brace steel pipe extends downwards and the bar of sweeping the floor fixes.
As preferably, locate with the jacking steel pipe mutually by the thick pillar steel pipe upper end of described diagonal brace steel pipe, and the middle-end of described diagonal brace steel pipe is located with diagonal brace mutually by short steel pipes, and described diagonal brace and diagonal brace steel pipe are the square crossing shape and distribute.
As preferably, the described bar of sweeping the floor is parallel distribution up and down with steel channel beam, and described diagonal brace fixes by diagonal brace fixed bit and steel channel beam.
Therefore, the cross support fixed system 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.
