Abstract

The invention relates to a large-span large-load pre-stress double-T plate and single-T plate frame structure system which comprises a longitudinal frame beam, large-span pre-stress double-T plates and single-T plate and a large-span frame cross beam, and is characterized in that the double-T plates and single-T plate are mounted on the two sides of a frame column. The large-span frame cross beam is arranged on the lower parts of the wing edge panels of the two double-T plates and single-T plate, so that (1) the special structure form of the double-T plates and single-T plate is utilized, the cross beam is arranged at the height from a wing plate to a rib bottom, the span is large and the load is also large, the height from the rib top to the wing plate is also higher and the frame cross beam can be arranged in the structure, and (2) the work load on the frame cross beam is endured by the double-T plates and single-T plate, the large-span pre-stress cross beam does not endure the upper work load any more and only endures the dead load and the horizontal force, and the cross height and the material cost are greatly saved.

Description

A kind of large-span prestressing force T plate, single T plate framework structural system

Art: building materials field.

Technical background: large-span prestressed T plate, it is extensive and outstanding that single T plate is used for the buildings such as single storey industry workshop, but use in multilayer large-span factory building or other large-span frame structure, cruciform bracing cross section is too high and cost is difficult to too greatly realization, severally to nobody shows any interest in, but, due in recent years, the raising of ordinary steel intensity, the development of Building technology, beam section span-depth radio constantly improves, by original 1/12, develop into 1/15 even 1/18, little span (10-14 rice) during large span is generally (10-30 rice) starts active, bring into use in the object of construction production of particular/special requirement once in a while.If but add again large load, and its cross section will break through 1/10, and even 1/8, even design load only has 10-15KN/m ², for 10 meters with the building of upper span, it is more than 1 meter or more than 1.4 meters that deck-molding will reach more than 1/10, and this generally becomes line of demarcation, forbidden zone architectural, and its floor height and cost are all large, is difficult to realize, and 15-24 rice span, 20-50KN/m ²building very general, floor height reaches more than 1/8, deck-molding, the floor height height of also having arrived more than 1.9-3 rice, for limit for height and again by highly receipts set-fee multi storied factory building, need reduce by the building of 1 layer to 2 layers, and about the cost of beam adds that furred ceiling expense reaches the half of whole factory building cost, just be more difficult to achieve, this belongs to a head-on blow, a mortal blow in fact to the new line that the large-span frame beam structure that this just always be nobody shows any interest in ties up to special engineering project, and visible large span is added large load and just is more difficult to achieve.

Summary of the invention: the invention provides a kind of large-span prestressing force T plate, single T plate framework structural system to solve an above difficult problem:

On the longeron of frame column both sides, symmetrical breaking puts 2 T plates at face angle or single T plate, breach symmetry further behind its face angle is stuck on frame column and is stitched together, or be placed on bracket disconnected to 2 T plates or single T plate, cruciform bracing is placed further at 2 T plate frange plate basifacials, utilize the higher space of large span again at the bottom of large Loading Plate wing plate to rib further thus the floor height do not affected shared by beam, main three aspects of load further on independent like this crossbeam, deadweight, horizontal force, working load is (as earthing, fire fighting truck, goods, concrete in-situ layer etc.) in, it only bears deadweight and horizontal force, working load is then by T plate, single T plate bears, which reduces its depth of section and Master Cost even furred ceiling expense and being achieved.Further, described large load refers to that design load Qd is at 7KN/m ²above.

Accompanying drawing explanation

Fig. 1 is a kind of large-span prestressing force T plate, single T plate framework crossbeam system floor map

Fig. 2 is a kind of large-span prestressing force T plate, single T plate framework crossbeam system elevational schematic view

It 1 is post; 2 is cruciform bracing; 3 is T plate; 4 for being stuck in the T plate on frame column, single T plate face chamfer breach.

Detailed description of the invention: the T plate 3 of band chamfer mouth 4, break and be placed on frame column 1 liang of side girder, cruciform bracing 2 is set under T plate 3 edge of a wing of post 1 both sides.

So just make full use of the special structure form of T plate 3 and the larger feature of large-span rib high larger space, arrange crossbeam, and do not account for or account for less floor height, crossbeam 2 does not just bear working load and reduces depth of section and material construction is achieved.

Claims

1. a large-span prestressing force T plate, single T plate framework structural system, comprise frame rails, large-span prestressed T plate, single T plate, large-span frame crossbeam, it is characterized in that: in frame column both sides, T plate, single T plate are installed, large-span frame crossbeam is arranged on two T plates, single T plate frange plate basifacial, like this: both can utilize T plate, the distinctive form of structure of single T plate, height upper and lower at the bottom of wing plate to rib arranges crossbeam, because large span is again large load, thus rib height is comparatively large to the height of wing plate, can not account for or occupy with space less; Working load again on cruciform bracing is just born by T plate, single T plate, and large-span prestressed crossbeam just no longer bears top working load, and only bears deadweight and horizontal force, just greatly saves depth of section and material construction.

2. a kind of large-span prestressing force T plate as claimed in claim 1, single T plate framework structural system, it is characterized in that: after angle, face can be cut away by 2 large-span prestressed T plates in frame column both sides, single T plate, 2 plate breach symmetries are stuck on post and are stitched together, also large-span prestressed T plate, single T plate can be broken and be placed on bracket, cruciform bracing is set at the frange plate basifacial of 2 plates.

3. a kind of large-span prestressing force T plate, single T plate framework structural system as claimed in claim, is characterized in that: described large load refers to that design load Qd is at 7KN/m ²above.
