Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deck plate used as a floor plate of a steel structure or the like, and in particular, it is used by inserting a bayonet collar into a bayonet reinforcing rib to connect a plurality of sheets in the width direction and placing concrete on the upper surface thereof. It is about deck plates.

[0002]

[Prior art]

 Reinforcing ribs are provided between the plurality of flat plate portions and at the end portions of one flat plate portion so as to project to the back surface, and the reinforcing ribs at the end portions of the flat plate portions are used as reinforcing ribs for insertion, and the horizontal brim at that end is used for the plate thickness. The deck plate, which is formed into a receiving collar that is lower by an amount corresponding to the above, while the other flat plate is bent downward at a right angle to form a plug-in collar, is disclosed in Japanese Utility Model Publication No. 60-89325 and Japanese Utility Model Publication No. 64325. This is a publicly known one proposed in Japanese Patent Publication No. 2908.

[0003]

[Problems to be solved by the device]

 By the way, in the deck plate described in Japanese Utility Model Laid-Open No. 60-89325, the two mating surfaces of the parallel portions (vertical web portions) of the reinforcing ribs are connected to each other by spot welding, seam welding, rivets, adhesive, etc. Since it sticks, it is possible to prevent the accident of concrete leaking out by opening the parallel part of the reinforcing ribs when pouring concrete, which is the purpose of this invention. There is a problem that the workability is poor, such as it is difficult to insert when inserting between parts, and once it is inserted it does not come off and it is difficult to lay it again.

On the other hand, in the deck plate described in Japanese Utility Model Laid-Open No. 64-2908, a protrusion groove is formed inside the parallel portion on the receiving flange side between the parallel portions of the reinforcing ribs for insertion, and a lower portion is provided at the tip of the receiving flange. While the inclined parts facing each other are provided, the insert flange is provided with a protrusion engaging with the protruding groove, and the flat plate part on the insert flange side is provided with a groove engaging with the inclined part. Although the plug can be prevented from slipping out of the parallel part of the plug-in reinforcing rib when the plug is connected to the plug-in reinforcing rib, the shape of the plug-in reinforcing rib and the plug-in flange is complicated. There is a problem that the manufacturing cost is high.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a reinforcing rib for insertion and a flange with a relatively simple shape, and the reinforcing flange for insertion has a reinforcement. It provides a deck plate with a structure that is easy to insert into the parallel parts of the ribs and at the same time relatively difficult to remove.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the deck plate according to the present invention is provided with reinforcing ribs projecting to the back surface between a plurality of flat plate portions and at one end portion of one flat plate portion. The reinforcing ribs of the above are used as the reinforcing ribs for insertion, and the horizontal flange at the end is formed into the receiving flange that is lower by the plate thickness, while the end of the other flat plate part is bent downward at a right angle to form the inserting flange. In this deck plate, the parallel portions of the reinforcing ribs for insertion are welded at predetermined intervals, and notches are provided at positions corresponding to the welding of the insertion flange.

[0007]

[Action]

 Since the parallel portions of the reinforcing ribs for insertion are welded at a predetermined interval, a gap sufficient for the insertion flange can be formed in the non-welded portion. In addition, since the notch is provided at the position corresponding to the above-mentioned welding of the insert flange, the weld flange and the surrounding area where it is difficult to make a gap can be escaped and the insert flange can be inserted between the parallel parts of the insert reinforcing ribs. The insertion is relatively easy and the removal is relatively easy, which improves the workability.

[0008] In order to enjoy such an action, it is not particularly limited, but it is desirable that the welding interval of the reinforcing rib for insertion is 250 to 700 mm, and if the interval is 250 mm or less, the insertion collar can be inserted. However, it is difficult to insert it again when it is forcibly inserted. On the other hand, when it is 700 mm or more, it becomes easy to insert the insert flange easily and at the same time, the locking function becomes insufficient. In addition, the size of the notch part of the insert brim is preferably notched so that the edge is separated from the center of the weld by 30 mm or more, and if it is smaller than this, it is difficult to replace it when inserting it by force. Become. Spot welding or seam welding can be used as the welding means.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of a deck plate according to the present invention, in which a is a front sectional view, b is a right side view of a, and c is a left side view of a.

The deck plate 1 is manufactured by roll-forming a thin steel plate. In this example, a reinforcing rib 5 composed of parallel portions 3 and 3 bent downward and a flange portion 4 having a triangular cross section continuously formed at the lower end thereof is formed between three flat plate portions 2. The parallel portions 3 and 3 are spot-welded 6 at predetermined intervals.

At the right end portion of the flat plate portion 2 at the right end (left and right in the figure), the parallel portions 7, 7 are bent downward and a flange portion having a triangular cross section continuously formed at the lower end thereof. 8 is formed with a reinforcing rib for insertion 9 having a cross-sectional shape similar to that of the above-mentioned reinforcing rib 5, and a horizontal brim at the end thereof is received to form a brim 10 which is bent by a thickness lower than that of the brim 10. Spot welding 11 is performed at predetermined intervals on the parallel portions 7, 7.

On the other hand, at the left end portion of the flat plate portion 2 at the left end, an insert flange 12 is formed by bending downward at a right angle, and spot welding 11 applied to the parallel portions 7 and 7 of the insert reinforcing rib 9 is formed therein. A notch 13 is formed at the same interval as the notch 13, and the notch 13 is cut to a size of 30 mm or more from the center of the spot weld 11 to the edge of the notch 13.

By the way, the interval between the spot welds 11 in the parallel portions 7 and 7 of the deck plate 1 having the above-described structure is formed to be 500 mm, and the notch 13 of the insert flange 12 is the same as the interval between the spot welds 10 (500 mm). ) And the size of the two pieces of deck plates 1 and 1 formed by notching the size from the center of the spot weld 11 to the edge of the notch 13 to 30 mm or more. Was inserted between the parallel portions 7, 7 of the other reinforcing rib 9 for insertion, and the insertion state was investigated. As a result, it was found that the insertion was relatively easy and the adjustment and movement of the insertion position was relatively easy, and the workability was good.

[0014]

[Effect of device]

 As described above, in the deck plate of the present invention, the shape of the reinforcing rib for insertion and the flange for the insertion may be a relatively simple shape which has been conventionally adopted, and the insertion flange can be easily inserted into the parallel portion of the reinforcing rib for insertion. At the same time, it is relatively difficult to pull out, so that the deck plates can be easily connected in the width direction during laying, and can be laid again, and the workability is good without deformation due to concrete placement.
