Abstract

(57) [Summary] (Corrected) [Purpose] When constructing reinforced concrete buildings, the bolts and nuts of the steel joints will interfere, so part of the deck plate for concrete placement must be cut out. Therefore, it is necessary to reinforce this excised part.-Provide the deck plate notch reinforcing support plate. [Structure] Deck plate notch reinforced support in which front and rear ends of long sides of a reinforcing support plate 1a having a Z-shaped section and having appropriate width and length are attached to the upper side of H-shaped steel of a steel frame connecting portion J with bolts and nuts B It is a plate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 Since this invention interferes with the bolts and nuts of the steel joints when constructing a reinforced concrete building with a steel frame structure, a part of the deck plate for concrete placement must be cut off. Therefore, since this cut-off portion must be reinforced, this is a device for a reinforcing support plate.

[0002]

[Prior art]

 Conventionally, in the above cases, a flat steel plate was attached to the steel frame joint by electric welding to reinforce it in order to receive the cut-out portion of the deck plate. The heating of the tensioned part reduces the frictional force and hinders it. Therefore, if the number of welded parts is reduced, the placed concrete may leak or drop in some cases, so improvement was required.

[0003]

[Problems to be solved by the device]

 Therefore, the object of the present invention is to provide a reinforcing support material that is rigid, has a simple shape, is easy to manufacture, and is easy to install in order to strengthen and support the deck plate when it is cut off as described above. I am trying.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is intended to reinforce a notch portion of a deck plate, the first of which is to connect the front and rear ends of the long side of a reinforcing support plate having a Z-shaped cross section and an appropriate width and length with a steel frame connection. It is a reinforcing support plate for the notch of the deck plate, which is attached and fixed to the upper side of the H-shaped steel by bolts and nuts. A second aspect of the present invention is a deck plate in which a bolt hole empty top and bottom sandwiching portion to be fitted and fixed to the upper side of the H-shaped steel in the steel frame connecting portion is formed at both ends to have an appropriate width and length, and a reinforcing support plate for the notch portion. Is.

[0005]

[Action]

 The first reinforcing support plate of the present invention constructed as described above is attached to the upper side of the H-shaped steel of the steel frame connecting part by fixing both ends of one long side with bolts and nuts as shown in FIG. Since the long side is extended to the outside, the notch in the deck plate can be fully replenished from below to support it. Further, the second reinforcing support plate of the present invention has the upper and lower portions of the H-shaped steel in the steel frame connecting portion formed with the bolt hole upper and lower clamping portions for fitting and fixing at both ends as shown in FIG. The notch of the deck plate can be reinforced and supported by attaching it to the required part of the deck with bolt nuts.

[0006]

【Example】

 An embodiment will be described with reference to the drawings. The first aspect of the present invention is to reinforce the notch O of the deck plate D in the steel frame connecting portion J in FIG. A reinforcing support plate 1a for a notched portion of a deck plate is formed by fixing both ends of one long side of the support plate 1a by bolts and nuts B for attaching a connecting plate P to the steel frame connecting portion J. In the second aspect of the present invention, in FIG. 3, the bolt hole 4 which is fitted and fixed to the upper side of the H-shaped steel at the steel-frame connecting portion J is formed with the empty upper and lower clamping portions 3 having appropriate widths and lengths formed at both ends. It is the reinforcing support plate 1b of the cutout portion of the deck plate.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Unlike the conventional method of attaching a thin iron plate to the steel frame connection portion to reinforce and support the notch of the deck plate, the present invention has a simple shape and is easy to manufacture and easy to attach. Therefore, no trouble will occur. Since there are two types of invented products, you can select and use one depending on the construction conditions.
