Description

STEEL PLATE WEIR FOR ONE UNITED MANUFACTURING CONCRETE}

The present invention relates to a signboard for integrally forming concrete to enhance the strength of the building and at the same time to reinforce the slab layer partitioning the floor by installing between the pillar and the pillar during building construction, in particular (not equal to each other) thickness By having a "b" section steel having an upper portion of the steel sheet beam, the ease of manufacture as well as reinforcement of the rigidity for shear or bending stress through the thickness adjustment of the section steel, if necessary, the upper bent support piece of the lower web or auxiliary steel Through this, the floor height of the building can be improved.

In general, steel plate beams are installed between the pillars and the pillars of the building, and various types of products are provided for the concrete-integrated steel plate beams filling and curing concrete mortar in the steel plate beams.

In the case of the steel sheet beams provided above, the steel sheet is simply bent or welded into a “U” shape, and the steel sheet beams do not require formwork or reinforcing bars compared with conventional concrete beam forming methods. This has the advantage of improving, shortening the air and having a beautiful appearance.

However, in the case of the steel sheet beams used in the above, the thickness of the steel sheet beams used to thicken the web, which is configured vertically on both sides of the lower steel sheet, that is, the side vertical steel sheet to support the placing pressure of the concrete mortar filled in the steel sheet beam There is a necessity to be made, and as the thickness of the steel sheet increases, the manufacturing cost increases, and this phenomenon has a problem that the thickness of the steel sheet becomes thicker accordingly as the dance of the side vertical steel sheet beams constituting the steel sheet beams increases.

As a means for solving such a problem, there is a patent application No. 10-2011-5145 "steel plate for concrete integral molding" has been published by the applicant of the present invention as an inventor.

That is, as shown in FIG. 24, the vertical vertical steel plate 2 (web) is welded between the upper and lower steel plates 1, 1 ', and plate to form a concrete mortar filling space on the inner surface. In constructing the beam, the concavities and convexities 4 are formed in the vertical direction on the side vertical steel plate 2, so that the rigidity that can support the placing pressure applied to the outer side when concrete mortar is placed on the inner space of the steel plate 3 This improves, and the flat vertical reinforcement plate is welded to both end portions of the side vertical steel plate 2, thereby reinforcing both ends of the side vertical steel plate 2, which are susceptible to weakness due to the unevenness 4. .

Therefore, the inventors of the present invention, the steel plate (3), even if the thickness of the side vertical steel sheet (2) is configured to be able to support the concrete placing pressure to reduce the weight of the steel plate (3) to reduce the production cost, etc. Although it was effective, the upper steel plate (1) (upper flange) formed on the upper surface of the two side vertical steel plate 2 (web) of the steel plate 3, the upper steel plate (1) In addition to the waste of materials in the () configuration, it was difficult to weld with the vertical steel plate 2 (web) on which the unevenness 4 was formed.

In addition, when the slab layer is to be constructed using the steel sheet 3, a deck plate is installed on the upper surface of the steel sheet 3, that is, the upper steel sheet 1 (upper flange), and concrete mortar is poured thereon. As the slab layer is constructed, the height of the slab is lowered as much as the thickness of the slab layer, thereby reducing the space utilization.

Utility model registered and devised by the applicant of the present invention as a means for preventing the lowering of the height caused by installing the deck plate on the upper steel plate 1 (upper plate) as above, and constructing the slab layer thereon 456012 has a corrugated steel beam for integrally forming concrete with improved interlayer height.

By installing the deck plate on the slab layer is installed thereon, it is possible to increase the height between the layers by the interval (L) of the upper steel plate 110 and the fixed plate 140 constituting the steel sheet beam (100).

Therefore, in the case of the steel sheet 100, the height of the floor can be increased by the distance between the upper steel plate 110 and the fixed plate 140, so that the space utilization can be improved, and the unevenness 131 is formed. Cutting the fixed plate 140 on the vertical steel plate 130, was to be difficult to work with welding.

In addition, in the case of the steel sheet provided in the above should be manufactured by manufacturing the steel sheet beam in the production plant according to the use, then welded, there was a disadvantage such as incompatible to change the structure as necessary.
