Detailed description of the invention
as depicted in figs. 1 and 2,adopt steel beam concrete slab on inhering architecture, increase a method for interlayer, concrete steps are as follows:
First, fixed steelring beam 3 on former concrete beam 2;
Secondly, steel ring beam 3 installs multiple steel longeron 6 along the length direction of building, do not allow in the middle of steel longeron 6 to disconnect, steel longeron 6 and steel ring beam 3 connecting portion adopt and are welded to connect;
Then, steel ring beam 3 installs multiple gooseneck 7 along the width of building, gooseneck 7 and steel longeron intersection area disconnect, by gusset plate and steel longitudinal beam welding firm, steel ring beam 3, steel longeron 6 and gooseneck 7 form girder steel;
Finally, pouring reinforcement concrete plate 1 on girder steel, makes girder steel and armored concrete slab form overall structure, so just on inhering architecture, adds interlayer.
Wherein, described steel ring beam 3, steel longeron 6 and gooseneck 7 make with No. 8 channel-section steels or No. 10 channel-section steels or No. 12 channel-section steels, unified, so that jointly stressed by newly-increased steel ring beam 3 by expansion bolt 5 with former concrete beam 2; The diameter of expansion bolt 5 is 12-20 ㎜, and the spacing between adjacent expansion bolt 5 is 200-300 ㎜; Spacing between adjacent steel longeron 6 is 600 ㎜, and the spacing between adjacent gooseneck 7 is 600 ㎜.Gusset plate weld all around is on the web of steel longeron.
Make girder steel and armored concrete slab form overall structure concrete operation method to be: first prop up concrete slab template, then concrete slab reinforcing bar is installed and pipe laying embedded part, finally build floorslab concrete, when girder steel adopts No. 8 channel-section steels to make, girder steel stretches into 20 ㎜ in armored concrete slab, when girder steel adopts 10 or No. 12 channel-section steels to make, girder steel stretches into 40 ㎜ in armored concrete slab; Before concreting plate, girder steel can eliminate rust, but does not allow brushing paint.Armored concrete slab maintenance is no less than 14 days, removes girder steel pollutant, brushing anti-corrosive primer and each two degree of finish paint after tearing a concrete slab template open.
When body of wall 1 increases interlayer, arrange stair activity properly, expediently downstairs use.
With the commercial and residential building of a floor height 5.2 meters, detailed explanation is done to the present invention below.
Certain commercial and residential building, design floor height 5.2 meters, frame construction, air-mixed concrete pieces used for filler wall is built by laying bricks or stones; Each household house 47-52 square metre, after resident family takes house, the first step is exactly structure adding layer, adopts steel beam concrete slab spacer structure to add layer.
First, arrange steel ring beam (making with No. 10 channel-section steels) at middle girder place, be that steel ring beam is fixed on former concrete beam by the expansion bolt of 18 ㎜ with diameter, expansion bolt spacing 250 ㎜ collar tie beam and frame column connecting portion, steel corbel established by pillar;
Install steel longeron again, steel longeron No. 10 channel-section steels are made, and adopt be welded to connect with steel ring beam connecting portion, spacing 600 ㎜;
Install gooseneck, gooseneck No. 10 channel-section steels are made, and adopt and are welded to connect, spacing 600 ㎜ with steel ring beam and steel longeron connecting portion; At steel longeron, gooseneck and steel ring beam jointing position, welding point plate attachment weld is adopted reliably and not to allow to injure steel longitudinal-beam web plate without exception; After acceptance(check), girder steel is eliminated rust on inspection; Must be noted that the setting of stair;
Slab form, can utilize girder steel to install template, but must arrange and shore in beam junction in length and breadth at steel in work progress; During formwork supporting plate, template face is arranged on below girder steel end face 40 ㎜ place, to ensure that girder steel gos deep into concrete slab 30-40 ㎜;
Install reinforcing bar, reinforcing bar adopts II grade or III grade of reinforcing bar of diameter 8 ㎜, rebar spacing 100-150 ㎜, way and double-layer reinforced mesh; Reinforcement net should be firm with channel-section steel spot welding, the elongated setting of upper reinforcement mesh sheet, and protective layer thickness is 15-20 ㎜;
Pipe laying embedded part is arranged, and is arranged, installs acceptance(check) after-pouring concrete by the various pipelines needing to bury underground.
Concrete curing must not be less than 14 days, and (when temperature is lower maintenance 28 days) can form removal,
After form removal, steel beam surface is cleared up, polishing, be coated with priming, each two degree of finish paint.
Service condition of the present invention is:
1. original structure design time considered may increase interlayer newly load, working load and use time load;
2. increase interlayer place and must have the reinforced concrete beam that can transmit load;
3. building storey height comparatively large (floor height is greater than 5 meters), can be separated into 2 layers, to increase using function by an original Rotating fields;
4. this spacer structure comprises newly-increased structural beam slab and original structure two parts, and two parts must form entirety, guarantees that load is rationally delivered on original structure layer, to ensure the use safety of spacer structure.
