Description
Technical field
The present invention relates to building engineering field, the steel wood group of specially a kind of cold bending thin wall Z-shape steel and straw board combination
Close superstructure.
Background technology
With the rapid development of the national economy, China's housing industry has obtained significant progress in recent years, become national warp
One of pillar industry of Ji.In order to ensure the lasting development of residence industry health, accelerating housing industrialization has become housing industry hair
The certainty of exhibition.The World Steel output statistics delivered according to International Steel Association, China's output of steel accounts for the world up to 7.8 hundred million tons within 2013
The 50% of total output.Supply exceed demand for China's output of steel, and steel construction is promoted the use of in dwelling construction and has become China
One of fundamental policies.Steel house major part component can be prefabricated in the factory, and site operation speed is fast, and quality is high, recuperability
By force, it is most suitable for realizing housing industrialization, and the usage amount of steel can be improved.
The reason of limitation steel house promotes and applies at present just has that project cost is high, and steel house project cost
It is the of high cost of superstructure and inside and outside wall board to improve main cause.Therefore it reduces steel house cost and first has to research and development bid
Lattice are reasonable, the superstructure of technology maturation, inside and outside wall board system.The importance of floor system is mainly reflected in its work in total
Occupy very big ratio in journey amount, therefore largely affect the cost and construction speed of entire engineering.Traditional steel
Bar concrete floor from it is great, toughness of material is bad, very big threat is constituted to earthquake-resistant structure.First, for building
Speech, floor quality account for the 50%~60% of building dead weight, and the increase of dead weight causes inertia force to become larger, and because of material itself
Toughness is inadequate, and earthquake-resistant structure is adversely affected；Second, in practice it has proved that bulky floor collapse is to cause people under geological process
The immediate cause of member's injures and deaths.Although the profiled sheet Combined concrete superstructure used at present has greatly reduced floor dead weight,
Due to the presence of concrete slab, dead weight is still very big.
Invention content
The present invention provides a kind of cold bending thin wall Z-shape steel and the steel and wood composite superstructure of straw board combination, it is therefore intended that solves
The project cost of steel house superstructure mentioned above in the background art is high, and traditional concrete floor shock resistance is bad
Problem.
To achieve the above object, the embodiment of the present invention provides a kind of cold bending thin wall Z-shape steel and the steel wood of straw board combination
Composite floor system, including superstructure tablet, the superstructure tablet be straw board, two superstructure tablets up and down parallel distribution, institute
It states and cold bending thin wall Z-shape steel is equipped between two superstructure tablets, the wing plates on two sides of the cold bending thin wall Z-shape steel passes through respectively builds knot
Structure gluing is connected on the superstructure tablet of upper and lower both sides, and the junction of the superstructure tablet and cold bending thin wall Z-shape steel is equipped with self tapping spiral shell
Nail, the cold bending thin wall Z-shape steel are respectively arranged on the left side and the right side cover board strip of paper used for sealing, and the cover board strip of paper used for sealing both ends are equipped with tapping screw,
The cover board strip of paper used for sealing is fixedly connected on by tapping screw between the superstructure tablet of both sides.
Preferably, the cover board strip of paper used for sealing is straw board.
Preferably, it is also filled with heat insulating and sound insulating material between the superstructure tablet of the both sides.
Preferably, the outer surface of the superstructure tablet is covered with metal skin.
Preferably, the cover board strip of paper used for sealing is also respectively provided at both sides the centre position at superstructure tablet both ends.
High-strength light is a big advantage of steel construction, since beam, column component are lighter, so the weight of building cover structure is to entirety
Weight is larger.Superstructure dead weight should be mitigated as possible when selection and design superstructure, superstructure can be thinned after weight reduction, directly drop
The low cost of superstructure part；From mechanical property, a kind of novel compositions superstructure is developed, a combination thereof component load-bearing ability is high,
Dead load is light, ductility is good, conducive to earthquake-resistant structure, is suitable for the civil buildings such as the house for having requirements for fortification against earthquake with important meaning
Justice.
China is large agricultural country, according to statistics, the stalk total amount about 7 × 10 generated every year8T, wherein 60% is rice/wheat straw
Stalk.Current existing utilization ways have：Straw-returning (accounts for about 20%)；(biogas, power generation, solid fuel bar, account for about 15% to the energy
~20%)；Construction material, paper making raw material and various additives etc. (account for about 15%).Still there is the stalk for accounting for total amount half not find
Outlet.Every to receive season, stalk is incinerated or is pushed into river embankment, constitutes the harm to society and environment.It may be said that stalk people
Good economic benefit and social benefit can be obtained again by making plank and can largely consuming agricultural crop straw, be a kind of novel build
Material type., from heavy and light, mechanics index of physics is good, and particularly static bending strength and elasticity modulus is larger, can be used as light-duty wood for it
Structure cladding plate.
Light gauge cold-formed steel shape is the main material for making light section steel structure, it is mainly existed with normal carbon steel plate or steel band
Section bar through roll-in or stamping forming various cross sectional shapes under room temperature.The utilization of its super buckling expands cold-rolled forming section
Use scope；Section molding is flexible, and up to over thousands of kind of specification, section material is reasonably distributed, cross section property coefficient such as the moment of inertia and
Resistance moment is relatively high.Since cold-rolled forming section is mainly used for optimizing cross sectional shape rather than increasing material utilization amount improving component
Bearing capacity, therefore cold-rolled forming section is also referred to as high efficiency section bar.Its process characteristic determines that its metal is reasonably distributed on section,
Good product quality, energy consumption is few, is widely used in building structure.
On this basis, it is proposed that both straw board and light gauge cold-formed steel shape are grouped together, form cold bending thin wall Z
Shaped steel-straw board composite floor, so as to apply in house.
The advantage of the invention is that：Composite floor system can make steel and straw board gives full play to material property, improve clean steel
The rigidity and Carrying Capacity of superstructure and pure wooden superstructure, meet actual demands of engineering；It can be manufactured in factory, on-site consolidation, largely
Reduce on-site construction time；More traditional concrete floor system dead weight is small, overall cost is low, high capacity, ductility are good, is conducive to resist
Shake；The production of composite floor system can also solve the problems, such as national stalk wasted resources, preserve the ecological environment.
