Description
Technical Field
The invention relates to a steel structure floor slab, in particular to a wedge-shaped middle rib floor slab.
Background
In the technical scheme commonly used for steel structures in the storage industry, floor panels are generally divided into two types, wherein one type is an S-shaped rolled floor slab, the floor slabs are mutually buckled and connected during installation, and then a floor slab fastener is installed to be connected with a floor slab beam; the other is C-shaped rolled floor slab, which is tightly attached together during installation and connected with the floor beam by self-tapping screws. The floor panel processing technology under the heavy load working condition is mostly rolling, and the reinforcing rib is welded in the place where the reinforcing rib needs to be manufactured after forming.
The main technical problems are as follows: firstly, the S-shaped rolled floor slab is inconvenient to install and high in cost. After the S-shaped floor slabs are buckled and connected with each other, a fastener needs to be installed from the bottom of the floor; the cost of the fastener is high. And secondly, the surface of the C-shaped rolled floor slab is uneven after splicing and installation. There is no mutual spacing connection structure between the C-type floor slabs. And fourthly, under the condition that the floor plate is long, the reinforcing ribs need to be turned and moved when being welded, the manual operation is inconvenient, the reinforcing ribs are inconvenient to weld, and the surface treatment needs to be carried out for many times after the welding.
Especially, the cost of surface treatment is higher and higher according to the current environmental protection requirement, the repeated surface treatment not only increases the cost, but also increases the pressure of environmental protection, and when the galvanized coil is adopted to manufacture the heavy-load floor slab, the floor slab and the reinforcing rib can not be connected by adopting the traditional welding mode. The galvanized material is not easy to weld, the strength after welding is not enough, and the welding position needs secondary surface treatment.
Disclosure of Invention
The invention aims to solve the technical problems and provides a wedge-shaped middle rib floor which can be manufactured by using a galvanized material without welding.
The technical scheme of the invention is as follows: the utility model provides a muscle floor in wedge, contains top surface, both sides face and along the inside bottom turn-ups of bending of both sides face, wholly bends by the steel sheet and forms, the side is perpendicular, inside has additional strengthening in the middle of the top surface, additional strengthening is the top surface and inwards bends into triangle-shaped space, the summit in triangle-shaped space cracks and is located on the top surface, the base in triangle-shaped space with the bottom turn-ups height of inwards bending is unanimous.
Furthermore, two rows of round holes are arranged beside the intersection line of the top surface and the side surface, and bolt holes are arranged on the bottom flanging and opposite to the round holes.
Furthermore, the top surface is provided with a plurality of long holes, and the long holes are formed by inward stamping and flanging.
Furthermore, the long holes are distributed on two sides of the top slot, and are regularly and symmetrically arranged in a mode of alternately arranging a horizontal shape, an inner splayed shape and an outer splayed shape in sequence.
Further, the steel sheet is a galvanized sheet.
Has the advantages that: at present, the yield of S-shaped floor slabs and C-shaped floor slabs is larger, and in most cases, heavy-load floor slabs with reinforcing ribs are welded, if the floor slabs are completely changed into a new structural form of wedge-shaped middle ribs, the welding cost of the reinforcing ribs is greatly saved. Meanwhile, the galvanized sheet is bent, so that secondary surface treatment is not needed, and the galvanized sheet is environment-friendly and can be recycled. The wedge-shaped notches on the two sides have the advantage of being assembled smoothly. The middle rib is formed by bending at one time without welding, and two ends of the middle rib fall on the cross beam to play a role in reinforcement. The mounting holes on the two sides are provided with windows for mounting bolts, and the short screws can penetrate into the mounting holes to be directly mounted, so that the prior long screw and the prior fastener are replaced, and the unevenness of the surface is avoided. Meanwhile, the holes on the surface of the floor slab are punched inwards, the surface is enhanced, and meanwhile, the light-transmitting window can be provided for the lower layer, so that the floor slab is attractive and practical.

Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
As shown in fig. 1, the wedge-shaped middle rib floor slab comprises a top surface 8, two side surfaces 9 and bottom flanges 10 which are bent inwards along the two side surfaces 9, the whole slab is formed by bending galvanized coiled materials, the side surfaces 9 are vertical, a reinforcing structure middle rib 3 is arranged in the middle of the top surface 8, the top surface is bent inwards to form a triangular space, a top slit 11 of the triangular space is located on the top surface 8, and the bottom side of the triangular space is consistent with the bottom flanges 10 in height.
As shown in figure 3, the side surfaces of the floor slabs are respectively provided with a male groove 2 and a female groove 1, and the two floor slabs can be butted with each other to ensure the flatness. The floor slab is formed by bending the middle ribs integrally without secondary processing. When the screw is processed, a certain amount of the seam 11 is reserved, when the screw is installed, the seam 11 on the top surface is completely closed through extrusion on two sides, and then the screw is fixed. The bottom edge of the triangle also falls on the cross beam, thus playing the role of supporting the middle part of the floor slab.
Two rows of round holes 5 are arranged beside the intersection line of the top surface and the side surface, and bolt holes 6 are arranged at the positions, opposite to the round holes, of the bottom flanging. As shown in fig. 1, is fixed to the cross member. The round hole 5 reserved on the floor can be drilled through the round hole 5 by a self-tapping screw and is connected with the floor beam on the turned edge of the floor, the installation is convenient and beautiful, no fastener is needed, the assembly cost is reduced, and the floor is more reliable.
As shown in fig. 2, the top surface has a plurality of elongated holes, which are formed by inwardly punching the flanges 4. The surface is provided with flanging holes to increase the strength of the panel and meet the requirements of lighting and fire fighting. The long holes are distributed on two sides of the top slit, and are alternately and symmetrically arranged in a horizontal, inner splayed and outer splayed mode in sequence. Meets the requirements of lighting and fire fighting.
