Abstract
The utility model provides a combined floor of bar-mat reinforcement sheets and profiled steel sheets by adopting spot welding and relates to load bearing units of building structure floor system. The combined floor can not only be used in industrial buildings but also in civil buildings and public buildings and especially can be greatly used in high-rise buildings, super high-rise buildings and steel structure buildings. By adopting the spot welding to properly connect the bar-mat reinforcement sheets and top flanges of the profiled steel sheets, the whole bar-mat reinforcement sheets play the role of shearing resistance, can improve the capacity of bending resistance and shearing resistance of the combined floor and enhance working performance of a combined floor of profiled steel sheets and concrete. Meanwhile, by adopting the spot welding to connect the bar-mat reinforcement sheets and top flanges of the profiled steel sheets, engineering construction can be accelerated, construction quality can be enhanced, and cost and labor can be saved.
Description
Technical field
The utility model technology relates to the bearing unit of building structure floor system, both can be used for industrial construction, also can be used for civilian construction and public building.Especially in high level, super highrise building and steel building, use in a large number.
Background technology
Existing homemade light face profiled sheet, and the concavo-convex rib profiled sheet of introducing in recent years of open type are furnished with corresponding socket cap weldering nail, porcelain ring and welding machine special, and certain application is arranged in high level, super highrise building, industrial construction.But at home, mostly profiled sheet is used as template and is used, do not give full play to the effect of profiled sheet, thereby on material, caused certain waste.In addition, the antiskid of light face open-type profiled sheet itself moves ability, and main mode of failure is reflected in the inefficacy that is connected of concrete and profiled sheet, and the need horizontal shear reinforcement of burn-oning in the steel plate top flange improves its shear resistance.Stipulate to need the half-arc type weld length of 50mm at present in the engineering, this causes the site operation trouble, labor intensive, and unfavorable factors such as poor welding quality have limited the application and the development of this type of steel plate to a certain extent.According to this situation, welded steel fabric sheet that we propose and profiled sheet spot welding form composite floor will play conclusive effect for the development that promotes this structure.
Summary of the invention
The utility model purpose is to provide a kind of Profiled Steel Sheet and Concrete Composite Floor form, is connected with the spot welding of profiled sheet top flange by the welded steel fabric sheet, plays the quickening speed of application, improves construction quality, saves cost and artificial effect; Simultaneously, utilize the welded steel fabric sheet, can improve the bending resistance shear resistance of compoboard, improve profiled sheet-concrete composite behaviour.
To achieve these goals, invent a kind of welded steel fabric sheet and profiled sheet top flange spot welded type composite floor form, comprise profiled sheet (see figure 1), welded steel fabric sheet (see figure 2), peg, wherein the welded steel fabric sheet is to be welded by horizontal bar reinforcing bar and vertical concrete steel muscle; It is characterized in that: lay the welded steel fabric sheet on the profiled sheet, wherein transverse reinforcement in the welded steel fabric sheet and profiled sheet crest location are spot-welded together.Longitudinal reinforcement places the below of transverse reinforcement.
Preferably, described profiled sheet is made up of the thin open-type profiled sheet of plate hight.
Preferably, to select diameter for use be 6 or 8 plain steel-bar to the horizontal shear reinforcement in the welded steel fabric sheet.Along plate longitudinal direction equidistant placement.Spacing is 100-300.
Preferably, it is 335 indented bars that the longitudinal reinforcement in the welded steel fabric sheet is selected intensity for use, is arranged in each groove of profiled sheet.
Preferably, transverse reinforcement and the spot welding of profiled sheet top flange are arranged in the shear span position of composite floor.
According to said structure, the form of the utility model reinforced mesh and profiled sheet spot welding structurally has following beneficial effect:
(1) improves the supporting capacity of plate, improve the stress performance of composite floor.Transverse reinforcement in the welded steel fabric and profiled sheet top flange are spot-welded together, and the welded steel fabric integral anti-shearing improves the bending resistance antiskid and moves ability, and then improves the supporting capacity of composite floor, improves the stress performance of composite floor.
(2) improve construction quality, accelerate speed of application, save manually material.The conventional method regulation, during profiled sheet top flange welding transverse reinforcement, weld length should be less than 50mm, and this influences speed of application and construction quality, labor intensive to a certain extent greatly.And the form of employing reinforced mesh and profiled sheet spot welding, this phenomenon can improve.Describe implementation process of the present utility model in detail below in conjunction with accompanying drawing, so that design philosophy of the present utility model is done deep understanding.
Description of drawings
Fig. 1 is a kind of light face open-type profiled sheet of employing of the present utility model;
Fig. 2 is the utility model transverse reinforcement, the longitudinal reinforcement that adopt and takes the lead peg;
Fig. 3 is the welded steel fabric sheet of employing of the present utility model;
Fig. 4 is the form of structure that the utility model forms;
The specific embodiment
With reference to Fig. 1-4, the utility model is a kind of welded steel fabric sheet and profiled sheet top flange spot welded type composite floor form, comprises profiled sheet 1, transverse reinforcement 2, longitudinal reinforcement 3, peg 4.Transverse reinforcement 2 and longitudinal reinforcement 3 when carrying out floor slab construction, at first carry out the laying of profiled sheet 1 at first at the prefabricated formation welded steel fabric of reinforcing bar streamline processing space sheet 5, carry out the installation of peg 4 then, and each is striden or strides layout every one.Then begin the work of mating formation and being connected of welded steel fabric sheet 5 with profiled sheet 1, the net sheet is mated formation and is carried out according to arrangement diagram, and welded steel fabric sheet 5 carries out spot welding by transverse reinforcement 2 with the top flange of profiled sheet 1 with being connected of profiled sheet 1 and is connected to form an integral body.
In a word, characteristics of the present utility model are to burn-on the welded steel fabric sheet to form a kind of new form of structure at profiled sheet top flange point, this form of structure is by the whole participation of welded steel fabric sheet shearing resistance, thereby improve the supporting capacity of compoboard greatly, simultaneously, by better simply spot welding form, can accelerate speed of application, improve construction quality, save cost and artificial effect.
