Description
Technical field
The present invention relates to civil engineering combination beam, more particularly to light-duty spliced steel-concrete building plate composite flat beam and its construction
Method.
Combination beam is a kind of girder construction combined by steel and concrete material, and this girder construction has given full play to two
The mechanical advantage of kind material, makes structure obtain larger rigidity and bearing capacity.Compared to common reinforced beam, combination
The construction period of beam is shorter, good toughness, possesses its incomparable advantage.
Concrete floor is held in steel beam flange as a kind of new structure type by composite flat beam, and by the girder steel wing
Edge welds shear connector, is tamped using cast-in-place concrete, among girder steel is embedded in into concrete floor, realized in superstructure afterwards
The state of secondary beam is not set, so as to meet the requirement of " arch without beam ", therefore, it is possible to reduce structure floor height to the full extent so that
The useful space of architecture storey increases, and its shortcoming is：1st, conventional composite beam causes fire protecting performance poor because steel leak outside,
It is also required to use fireproof coating in use；2nd, because girder steel depth of section is smaller, section rigidity is relatively low preferably to fit the flat beam of conventional combination
For in the structure of medium and small span, and dead load is larger, and construction is also relatively complicated.
The content of the invention

Inverted T shaped girder steel junction steel plate 7 is fixed between 2 lower ends, the steel plate of falling tabula 5 is set between the front and back end of web 2 for the section steel beam of falling T.
Further, the height of described horizontal steel column 6 is not less than the 1/2 of the height of web 2.
The construction method of light-duty spliced steel-concrete building plate composite flat beam, its step are：
Step 1：Multiple H profile steels are subjected to segmentation and form multiple inverted T shaped steel；Multiple shaped steel of falling T are set up in parallel, inverted T shaped
Steel be arranged side by side after web 2 between light construction filler 4 is set；
Step 2：The top of each web 2 of inverted T shaped steel is provided with the rectangle shearing resistance tenon 22 and shearing resistance groove 23 to distribute alternately；
A row preformed hole 24 is provided with web 2, preformed hole is located at the lower section of rectangle shearing resistance tenon 22 and shearing resistance groove 23, and preformed hole 24 connects
The reinforcing bar of concrete building intralamellar part；
Step 3：Distribution bar or pipeline are stretched into the preformed hole 24 of the web 2 of inverted T shaped steel, casting concrete, shape
Into light-duty spliced steel-concrete building plate composite flat beam.
Beneficial effects of the present invention：
The present invention uses inverted T shaped steel, eliminates top flange, while employs rectangle shearing resistance tenon 22 and shearing resistance groove 23, significantly
Economy and the construction period of composite flat beam are improved, web 2 is directly protruding into inside floor, it is only necessary to the inverted T shaped girder steel of polylith
Rigidity can be lifted by carrying out splicing, simplify work progress, lifting construction speed.
