Abstract
The utility model relates to an assembly type steel-concrete structure combined hollow floor. The assembly type steel-concrete structure combine hollow floor comprises a concrete board (3), a grid steel board (5), a plurality of bolts (1), a plurality of nuts (2) and a plurality of steel pipe sleeves (4), wherein one end of each bolt (1) penetrates through the grid steel board (5), each bolt (1) is sleeved with the corresponding steel pipe sleeve (4), the concrete board (3) is placed at the top ends of the steel pipe sleeves (4), the concrete board (3) is in parallel with the grid steel board (5), each bolt (1) penetrates through the concrete board (3), and the top end of each bolt (1) is provided with the corresponding nut (2). By means of the characteristics of ultra-high strength, tenacity, impact resistance, fire resistance, corrosion resistance, high density, high durability and the like of high-performance material, the assembly type steel-concrete structure combined hollow floor overcomes the defects that a prefabricated part is large in self weight, difficult to convey, inconvenient to maintain and troublesome to lift, and the structural component having excellent performance is provided for housing industrialization.
Description
Technical field
This practicality has related to a kind of assembling steel-concrete structure combined hollow floor, specially refers to a kind of prefabrication, and construction is simple, the composite floor of convenient transportation.
Background technology
Precast assembly structure has the feature of " green construction ", " energy-conserving and environment-protective ", and industrialization flowing water prefabricated units industrialization degree is high; Reusable after the disposable input of moulding form and production equipment, consumptive material is few, economizes on resources and expense; The impact of construction on surrounding enviroment can be avoided or alleviate to site assembly, connection; The utilization of prefabrication and assembly construction technique, drops into relatively human resources and reduces; Mechanization degree is significantly improved, and labor intensity of operating staff is effectively alleviated; The assembling of prefabricated units, shortens the engineering construction cycle; Batch production precast unit, does not adopt wet trade, thereby reduced on-site concrete, waters the generation that pounds " rubbish source ", adopts precast unit, makes constructional materials in transportation, handling, stacking, material controlling process, has reduced various dust pollutions.
Summary of the invention
The present utility model object is to solve the large problem of existing concrete slab weight, and a kind of assembling steel-concrete structure combined hollow floor is provided, and it has reduced dead load, is convenient to transportation.
In order to complete this practical goal of the invention, this practicality by the following technical solutions:
A kind of assembling steel-concrete structure combined hollow floor of the present utility model, wherein: it comprises: concrete slab, grid steel plate, several bolts, several nuts and several steel pipe sleeve pipes, one end of several bolts is through grid steel plate, on above-mentioned each bolt, be set with a steel pipe sleeve pipe, concrete slab is placed on the top of steel pipe sleeve pipe, concrete slab is parallel to above-mentioned grid steel plate, and above-mentioned each bolt, through concrete slab, is equipped with a nut on the top of each bolt;
A kind of assembling steel-concrete structure combined hollow floor of the present utility model, wherein: described bolt is uniformly distributed along the horizontal and vertical of grid steel plate;
A kind of assembling steel-concrete structure combined hollow floor of the present utility model, wherein: described grid steel plate comprises: several vertical steel bands and several horizontal steel bands, placement parallel to each other between vertical steel band, placement parallel to each other between horizontal steel band, vertical steel band and the horizontal steel band layout that is perpendicular to one another, on the contact point of vertical steel band and horizontal steel band, have through hole, each bolt is through through hole;
A kind of assembling steel-concrete structure combined hollow floor of the present utility model, wherein: described concrete slab is high strength fibre concrete slab more than intensity 80MPa.
A kind of assembling steel-concrete structure combined hollow floor of the present utility model is compared with existing similar concrete segment, the utility model utilizes the superhigh intensity of very-high performance fibrous concrete member, toughness, impact resistance, fire-resistant, corrosion resistant, the features such as compactness height and high-durability, in conjunction with steel structure framework and mounting fastener, employing engineering is pre-formed, field module assembling construction process, because main structure adopts ultra-high concrete material, reasonable stress, deadweight is 20% of traditional components, prefabricated units have been overcome from great, transport not difficult, member safeguards that inconvenience waits lifting trouble, for housing industrialization provides a kind of structural element of superior performance.
