Abstract
The utility model provides an upper and lower double -deck concrete slab structure for girder steel, the both sides welding of girder steel upper end has upper reinforced concrete supporting angle steel, and permanent template is shelved on upper concrete slab supporting angle steel, the girder steel lower extreme still is equipped with the reinforced concrete of lower floor, and the concrete slab of lower floor supporting angle steel welds on the girder steel, suspends reinforcing bar and spacer bar interval arrangement in midair, and weld respectively on girder steel and supporting steel plate at both ends. The utility model discloses a double -deck reinforced concrete floor, to the girder steel, the lower floor sets up reinforced concrete board difficulty, and it increases the supporting steel plate processing to adopt. The adoption is suspended the reinforcing bar in midair and is welded the lower flange department in the steel beam web plate position with the supporting steel plate, and the concrete slab of lower floor can not produce adverse effect to the part of the lower flange of girder steel like this. It is thus clear that, with the multi -region check individual layer concrete slab contrast that is used for the girder steel for the upper and lower double -deck concrete slab of girder steel makes only district's check of whole room, obtains to seal smooth room ceiling, reduces ventilation system's complexity, is convenient for remove the hydrogen that gathers, satisfies functional requirement, eliminates operation hidden danger, has better comprehensive benefit.
Description
Technical field
The utility model relates to the concrete board constructions in power plant, especially relates to a kind of Dual-layer concrete board constructions for girder steel.
Background technology
The battery room of power plant is generally positioned at main building or centralized Control is indoor, sometimes has hydrogen and overflows, gather at battery room ceiling in battery room.Usually in battery room, be provided with ventilation system, drain the hydrogen gathered in time.Therefore require that the ceiling of battery room is smooth, and should not furred ceiling be established.The battery room being arranged in main building or centralized Control indoor is general not at top layer, and its ceiling is not roofing, is also furnished with other room above, if the secondary beam of ceiling turned over, can affect room, top.In addition because battery room ceiling is separated into multiple districts lattice by transverse and longitudinal secondary beam, the hydrogen gathered is divided into multiple part, cause Design of Ventilation System complicated, and operation exists hidden danger.Even if turn on ceiling secondary beam, because battery room ceiling is the ground of a upper floor simultaneously, require smooth equally, even if adopt light material to fill, also can increase deadweight, cause expense to increase.Due to the existence of floor amount of deflection, easily ftracture in ground, upper strata, sense organ is bad.
Utility model content
The purpose of this utility model is to provide a kind of Dual-layer concrete board constructions for girder steel, closes smooth ceiling, reduce ventilation system complexity, eliminate and run hidden danger, improve the object of comprehensive benefit to reach to obtain.
For achieving the above object, the utility model provides a kind of Dual-layer concrete board constructions for girder steel, comprise girder steel, top reinforcement concrete slab, it is characterized in that: both sides, girder steel upper end are welded with top reinforcement concrete slab supporting angle steel, permanent template is shelved on the concrete slab supporting angle steel of upper strata; Girder steel lower end is also provided with lower floor's armored concrete slab, and lower-layer concrete plate supporting angle steel is welded on girder steel, and suspention reinforcing bar and bearing bar interval are arranged, two ends are welded on girder steel and supporting steel plate respectively.
For preventing the stressed displacement of supporting steel plate, the oblique layout of bearing bar.
The utility model adopts double layer reinforced concrete floor, and for girder steel, lower floor arranges armored concrete slab difficulty, adopts and increases supporting steel plate process.Adopt suspention reinforcing bar supporting steel plate to be welded in the bottom flange place of steel beam web plate position, such lower-layer concrete plate can not have a negative impact to the local of the bottom flange of girder steel.The oblique layout of bearing bar, if produce lateral force to supporting steel plate during construction, can play a supporting role, prevent supporting steel plate from conjugating.
If adopt light material that required absolute altitude is filled out at lower-layer concrete plate top, and as the template of upper strata concrete slab, then add the deadweight of whole floor, levels concrete slab is stressed also indefinite in addition.If adopt profiled sheet to make permanent bed die, cost is higher, also will purchase separately, construction inconvenience.Adopt supporting angle steel to be welded on girder steel, wooden form be shelved on supporting angle steel as permanent template, very convenient just can colligation upper strata concrete slab reinforcing bar concreting.
Visible, contrast with the multi-grid one-course concrete plate for girder steel, Dual-layer concrete slab for girder steel makes whole room only have district's lattice, obtain and close smooth room ceiling, reduce the complexity of ventilation system, be convenient to the hydrogen gathered to drain, content with funtion demand, eliminate and run hidden danger, there is good comprehensive benefit.
Accompanying drawing explanation
Fig. 1 is the Dual-layer concrete board constructions plan view for girder steel;
Fig. 2 is used for the Dual-layer concrete slab cross section A-A section of structure of girder steel;
The Dual-layer concrete board constructions detail drawing of Fig. 3 girder steel.
Detailed description of the invention
With reference to Fig. 1, with reference to Fig. 2, with reference to Fig. 3, the utility model comprises top reinforcement concrete slab, permanent template 9, the partition wall 12 that girder steel 1, lower-layer concrete plate supporting angle steel 2, upper strata concrete slab supporting angle steel 3, lower-layer concrete plate supporting steel plate 4, the lower floor's armored concrete slab suspending reinforcing bar 5, bearing bar 6, lower plywood reinforcing bar 7 and lower plywood concrete eight formation in midair, top plate reinforcing bar 10 and top plate concrete 11 are formed.During installation, first install girder steel 1, then lower-layer concrete plate supporting angle steel 2 is welded on girder steel 1.Suspention reinforcing bar 5 and bearing bar 6 interval are arranged, two ends are welded on girder steel 1 and supporting steel plate.Following formwork, colligation lower plywood reinforcing bar 7, then builds lower plywood concrete eight.Next upper strata concrete slab supporting angle steel 3 is welded on girder steel 1, permanent template 9 is shelved on supporting angle steel 3.Colligation top plate reinforcing bar 10, then builds top plate concrete 11.Until lower plywood intensity meets the demands, after stripping, build partition wall 12 by laying bricks or stones.
