Abstract
The utility model relates to a reinforced concrete combination masonry grid beam with long span, which is characterized in that the utility model consists of a grid beam submontane joist(1), a tie column(2), filling materials(3) and structural beam and slab(4), the lower joist(1) is fixedly connected with the structural beam and slab(4) by the tie column(2), the filling materials are filled around the tie column(2). Both the lower joist(1) and the structural beam slab(4) are reinforced concrete structure. The utility model has the advantages of reducing material, saving cost and shortening construction period.
Description
Technical field: the utility model relates to a kind of large-span steel-reinforced concrete combined masonry grid beams.
Background technology: in China's economic construction coastal area with fastest developing speed, the construction of many industrial occupancys is being filled out extra large beach on the ground recently since the reform and opening-up, and these newly construct the factory buildings and often adopt pile foundation to support superstructure.Because the face of land is for stablizing factory building and warehouse (the live load 10KN/M higher to some instructions for uses as yet in its sedimentation of banketing recently
2-30KN/M
2) designer generally adopts pile foundation to support earth construction, this class earth construction often adopts reinforced concrete cast-in-situ beam slab system.The investment of its earth construction of single is accounted for the 40%-60% of whole building investment.Usually the earth construction that designs on soft base generally adopts span comparatively economical less than 12 meters reinforced concrete beam and plate, but such pile foundation supporting capacity be not fully utilized (it is higher to join a coefficient) often.The brick external mold of general employing when this class formation is constructed in addition, waste of material is bigger, and construction period is longer simultaneously.Therefore the earth construction that designs on the existing soft base exists: 1, for reducing the pile foundation that beam span is provided with, and owing to the geology reason, bearing capacity foot often, economic indicator is bad.The stock mould consumption is big when 2, constructing, and increases construction costs.3, the construction period is longer.
Summary of the invention: the purpose of this utility model is a kind of large-span steel-reinforced concrete combined masonry grid beams of design, and it can reduce material, saves cost, shortens the construction period.
The purpose of this utility model realizes by following technical method, design a kind of large-span steel-reinforced concrete combined masonry grid beams, it is characterized in that: grid beams is by joist (1), constructional column (2), packing material (3), structure beam slab (4) are formed down, following joist (1) is fixedlyed connected with structure beam slab (4) by constructional column (2), at constructional column (2) packing material (3) is arranged all around.
Described joist (1) down is a reinforced concrete structure with structure beam slab (4).
Described constructional column (2) is a masonry component.
On the face of soft base, build pile cap by certain distance, build down joist simultaneously, following joist adopts steel concrete; On following joist, reserve and get in touch with structure construction post reinforcing bar down, build the web packing material by laying bricks or stones by the masonry structure requirement; Build superstructure beam slab and constructional column concrete, superstructure beam and constructional column concrete are steel concrete.The constructional column of last underbeam is got maximum tension stress by steel concrete axial tension component arrangement of reinforcement.
Characteristics of the present utility model are: 1, reduce the steel concrete consumption.2, the construction mould of the time need not laying bricks.3, the rigidity of structure is big, can strengthen the span of earth construction, makes full use of pile foundation supporting capacity (it is low to join a coefficient).4, cost is low, bearing capacity height, easy construction.
It can also embody by the cost in actual engineering contrast, is twin spans 18.0M reinforced concrete cast-in-situ post light-steel roofing structure as certain warehouse, and building length overall 117.0M, post be apart from 9.0M, width 36.0M, the high 6.8M of capital.Engineering geology distributes as follows: the face of land is a 3.0M-4.0M backfill recently, is downwards 40M-45M mud, is middle weathered rock formation then.Mobile load 15KN/M2 is used on ground.By " " mode designs warehouse floor to reinforced concrete cast-in-situ grid beams plated construction, be with 84 of 500 pile for prestressed pipe, the about 4000M of total length, ground and the about 2000M of cushion cap concrete amount, the about 260T of reinforcing bar, tile floor mould 1600M.Adopt the utility model mode to design warehouse floor: only to use 54 of 500 pile for prestressed pipe, the about 2400M of total length, ground and the about 1200M of cushion cap concrete amount, the about 150T of reinforcing bar, 1100M3 lays bricks, the price differential of two kinds of used constructional materialss of design scheme of contrast is about 30%, is about 40% as considering operating expenses construction costs difference, this shows that the benefit of saving cost is considerable.
Below in conjunction with the embodiment accompanying drawing the utility model is done furtherly:
Description of drawings: accompanying drawing 1 is that embodiment illustrates schematic diagram.
Among the figure: 1, following joist; 2, constructional column; 3, packing material; 4, structure beam slab.
The specific embodiment: large-span steel-reinforced concrete combined masonry grid beams, to form by following joist 1, constructional column 2, packing material 3, structure beam slab 4, following joist 1 is fixedlyed connected with structure beam slab 4 by constructional column 2, and packing material 3 is arranged around constructional column 2.Following joist 1 is reinforced concrete structures with structure beam slab 4; Constructional column 2 is masonry components.Total requires to press the method construction of masonry back, promptly builds a wall earlier and afterwards waters constructional column and top board, and it is stressed jointly that steel concrete and brickwork are closely combined as a whole, and satisfies structure for the masonry component durability and uses design reference period.
On the face of soft base, build pile cap by certain distance, build down joist 1 simultaneously, following joist 1 adopts reinforced concrete structure; Structure is reserved on following joist 1 and is got in touch with structure construction post reinforcing bar 2 down at a certain distance, builds web packing material 3 by laying bricks or stones by the masonry structure requirement, and web packing material 3 is flushed with constructional column reinforcing bar 2; On web packing material 3, build superstructure beam slab and constructional column concrete 4, superstructure beam and the constructional column concrete 4 same steel concrete that adopt.Constructional column reinforcing bar 2 is got maximum tension stress, presses steel concrete axial tension component arrangement of reinforcement.Total requires to press the method construction of masonry back, promptly builds a wall earlier and afterwards waters constructional column and top board, and it is stressed jointly that steel concrete and brickwork are closely combined as a whole, and satisfies structure for the masonry component durability and uses design reference period.
Form the drag system by structural mechanics and material mechanics principle, make it stressed reasonable, and can reduce construction costs again.
