The enhanced closed profiled steel sheet of the utility model provides product support for realizing large-span beamless space; the product has strong applicability, and can be used as a roof, a floor and other suitable purposes; the production technology and the process are simple, the manufacturing cost is low, and the popularization and the application are easy.
Description
Technical Field
The utility model relates to an enhancement mode closed die mould steel sheet belongs to assembly type building technical field.
Background
The large part of the bearing capacity of the building structure is used for bearing the dead weight, the strength-to-weight ratio (the ratio of the bearing capacity to the dead weight) is an extremely important index for measuring building materials and building products, particularly for plate-type crossing flexural members, the strength-to-weight ratio is a key factor, in addition, the larger the dead weight is, the larger the earthquake action is, and the dead weight is one of the decisive factors of the structure and the basic design.
At present, light boards at home and abroad are mainly color steel composite boards, and the defects that the light boards need to be matched with profile steel purlins for use in order to realize a certain span, the construction process is complex, and the light boards cannot be used as floor boards particularly. Some lightweight concrete plates are also produced in domestic markets, but the lightweight concrete plates have poor strength-to-weight ratio and complex manufacturing process, are limited in application, and basically cannot be used as floor plates with certain span.
In steel structure house building, the floor structure mostly adopts profiled steel sheet floor support plate. The floor system has the advantages of short construction period, convenient field operation, excellent building integrity and the like. Because the floor carrier plate is applied the volume extensively in steel construction building, consider the economic nature of floor carrier plate, the profiled sheet base plate generally adopts less thickness value. Meanwhile, the dead weight of the common concrete is large, and the dead weight of the concrete occupies a large proportion in external load, so that the allowable unsupported clear span of the profiled steel plate is usually not more than 3 m. When the floor span is great, often need set up secondary beam or interim support, bring inconvenience for the construction, increased engineering cost moreover.
Disclosure of Invention
The invention aims to provide a closed profiled steel sheet, which is used for overcoming the technical defects.
In order to achieve the purpose, the upper flange cavity of the conventional closed profiled steel sheet is filled with materials, so that the section inertia moment of the profiled steel sheet is increased, the strength and the rigidity of the profiled steel sheet are increased, the deflection of the profiled steel sheet under the load action is reduced, the unsupported span of the profiled steel sheet is increased, and the use cost performance of the profiled steel sheet is improved.
An enhanced closed profiled steel sheet comprising a closed profiled steel sheet having an upper flange cavity, characterized by: the upper flange cavity of the closed profiled steel sheet is provided with a filling material, and the filling material and the profiled steel sheet are integrated.
The reinforced type closed profiled steel sheet as described above is characterized in that: the close-fitting double-web plate of the closed profiled steel sheet is connected with a reinforcement, and the closed cavity at the upper flange can bear the external force increased when the filling material is filled.
The reinforced type closed profiled steel sheet as described above is characterized in that: the close-fitting double web connection of the closed profiled steel sheet is by means of adhesive bonding, welding or mechanical joining.
The reinforced type closed profiled steel sheet as described above is characterized in that: the filling material in the cavity of the upper flange of the closed profiled steel sheet adopts injection molding, concrete or metal profiles.
The reinforced type closed profiled steel sheet as described above is characterized in that: once filled, the filler material will not be disassembled from the closed profiled steel sheet and will act together with the closed profiled steel sheet.
Further, the closed-type profiled steel sheet is a metal plate having a thickness of not more than 2.0 mm.
Compared with the prior art, the beneficial effects of the utility model reside in that: under the conditions of light weight, high strength and equal span and load of the profiled steel sheet, the self weight is lighter than that of the traditional profiled steel sheet floor slab, and product support is provided for realizing a large-span beamless space; the product has strong applicability, and can be used as a roof, a floor and other suitable purposes; the production technology and the process are simple, the manufacturing cost is low, and the popularization and the application are easy.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1, a reinforced type closed profiled steel sheet includes a closed profiled steel sheet 1 having an upper flange cavity 2, a filler 3 in the upper flange cavity 2 of the closed profiled steel sheet 1, and the filler 3 is integrated with the profiled steel sheet 1. Furthermore, the close-fitting double webs 4 of the closed profiled steel sheet 1 are connected with a reinforcement, and the closed cavity at the upper flange can bear the external force increased when the filling material is filled after the reinforcement. The close-fitting double webs 4 of the closed profiled steel sheet 1 are connected by welding. The filling material 3 in the upper flange cavity 2 of the closed profiled steel sheet 1 is made of concrete material, and after solidification, the filling material and the closed profiled steel sheet act together to bear load. The closed-type profiled steel sheet was a galvanized steel sheet having a thickness of 1.0 mm.
Example 2
Still as shown in fig. 1, schematically, a reinforced type closed profiled steel sheet includes a closed profiled steel sheet 1 having an upper flange cavity 2, a filler material 3 in the upper flange cavity 2 of the closed profiled steel sheet 1, and the filler material 3 is integrated with the profiled steel sheet 1. Furthermore, the close-fitting double webs 4 of the closed profiled steel sheet 1 are connected with a reinforcement, and the closed cavity at the upper flange can bear the external force increased when the filling material is filled after the reinforcement. The close-fitting double webs 4 of the closed profiled steel sheet 1 are connected by adhesion. The filling material 3 in the upper flange cavity 2 of the closed profiled steel sheet 1 is an injection moulding material, which acts together with the closed profiled steel sheet to bear the load. The closed-end profiled steel sheet is a thin-walled steel sheet with a thickness of 0.8 mm.
The invention has been described in connection with the accompanying drawings and examples, which are not intended to be limiting and are shown in the drawings as illustrative of one embodiment. It should be understood by those skilled in the art that other persons may make similar or equivalent designs to the present invention in light of the teachings of the present invention. It is to be noted that all obvious modifications and similar or equivalent arrangements are included within the scope of protection of the present invention, without departing from the design spirit of the present invention.
