化や交通量の増大により床版の損傷が著しく、その補修
に膨大な費用がかけられている。(Prior Art) Reinforced concrete slabs have been widely used in road bridges, urban expressway viaducts, and the like. However, due to the increased weight of vehicles and the increase in traffic volume, the floor slabs are severely damaged, and a huge amount of money is spent on repairing them.

のずれ防止作用を付加しておく必要がある。In the composite structure of steel plates and concrete that make up such composite slabs, the steel plate acts as a formwork before the concrete hardens, and after hardening, the steel plate and concrete are integrated to create a composite structure. In order to obtain this structure, the rigidity of the plate must be ensured to withstand the weight of the concrete during concrete pouring, and the steel plate and concrete must be bonded together so that the steel plate and concrete become one body after the concrete hardens. It is necessary to add an action to prevent slippage.

What you can't do. Furthermore, when used as a formwork during concrete hardening, it may be necessary to separately reinforce beams or the like to prevent out-of-plane deformation, and the current construction method lacks rationality.

There is. As a preventive measure, it may be possible to increase the number of structural steels installed, but this poses problems such as an increase in steel cost and welding man-hours, and the possibility that the structural steels act as foreign objects in the concrete and cause defects during concrete filling. There are problems such as increasing numbers of people.

成構造を採用している。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention applies a shaped steel member, for example, to a steel plate having continuous unevenness formed on the surface, for example, a steel plate having diamond-shaped continuous protrusions. A composite structure is adopted in which a steel plate and concrete are integrated by joining a plurality of shaped steel members at predetermined intervals in the direction and burying the shaped steel members in concrete.

目状にしている突起をいう。Here, continuous unevenness refers to a surface structure formed by continuous depressions or protrusions or repeated unevenness. For example, when providing diamond-shaped continuous protrusions, the continuous protrusions are curved. If it is provided in a mesh pattern, it is best to press it together with the 4-metal plate at 4 degrees Celsius.
It refers to a protrusion in which protrusions raised above a certain height extend continuously in a straight line on the surface, and where the protrusions intersect with each other to create a diamond-like pattern on the surface of the subdivision.

設定できる。Shaped steel members are not just plate-like members; their specific shape does not matter as long as they exert a kind of pressing effect on concrete, and their arrangement may be irregular to some extent even if they are arranged parallel to the surface of the steel plate. However, from the viewpoint of workability, it is preferable to arrange them in parallel in a certain direction. The interval etc. can be set as appropriate.

（作用）
以下、本発明の概要を実施例に対応する図面により説明

ート３中に埋没させることにより、鋼板１とコンクリー
ト３とを一体化させた合成構造である。As shown in FIG. 1, the present invention involves welding, etc., a shaped steel member 2 in a fixed direction at a predetermined interval on one side of a steel plate 1 having a continuous uneven portion 8 consisting of diamond-shaped continuous protrusions 6. It is a composite structure in which the steel plate 1 and the concrete 3 are integrated by joining a plurality of them and embedding the shaped steel member 2 in the concrete 3 as shown in FIG.

一定の高さ以上で***した突条１１が直線状に連続して
その面上を延び、突条が互いに交差して小区画の面部分
１２を菱目状に画定している突起をいう。The steel plate 1 having the diamond-shaped continuous projections 6 has a surface shape as shown in FIG. 3, and the diamond-shaped continuous projections 6 are as follows.
It refers to a protrusion in which protrusions 11 raised above a certain height extend linearly and continuously on the surface, and the protrusions intersect with each other to define the surface portion 12 of the subdivision in a diamond pattern.

には限定されないが、コンクリートの現場打設を考慮す
ると、コンクリートとの付着強度の信転性の点より２１
以上あるのが望ましい。As a method for manufacturing the steel plate 1 having the diamond-shaped protrusions, a method of transferring the protrusions to the rolled steel plate by a continuous hot rolling method using a grooved roll is highly productive and effective. The size of the diamonds and the height of the protrusions are not particularly limited, but considering the on-site placement of concrete, the size of the diamonds and the height of the protrusions are 21
It is desirable that there be more than that.
また、菱目状の区画の内角θは１００以上とするのが望
ましい、これは、コンクリートとの付着強度に関係し、
菱目状の区画の内角θが１０°より小さくなると、憂目
の区画内の面部分１２へのコンクリートの充填が阻害さ
れ、付着強度が急激に低下するためである。In addition, it is desirable that the internal angle θ of the diamond-shaped section is 100 or more. This is related to the adhesive strength with concrete,
This is because if the internal angle θ of the diamond-shaped section is smaller than 10 degrees, the filling of concrete into the surface portion 12 within the diamond-shaped section is inhibited, and the adhesion strength is sharply reduced.
第４図は、予備試験として形鋼部材を用いない場合につ

度との関係を示したものである。FIG. 4 shows the relationship between the interior angle of the diamond-shaped section and the adhesion strength between the steel plate and concrete in the case where no shaped steel members were used as a preliminary test.

起の高さは４．５ ｖｓＯものを用いた。As a result of testing according to the pull-out test method commonly used for adhesion testing of deformed reinforcing bars, it was found that the adhesion strength sharply decreased when the internal angle of the concave section became less than 10''.The concrete shown in Table 1 was used. It was poured to a constant thickness.The height of the diamond-shaped protrusions was 4.5 vsO.

しを防止することが出来る。With this composite structure, compared to the case of using the studs mentioned above as the conventional technology, the step of setting the stand can be omitted, and the diamond-shaped continuous protrusions also have the effect of improving the out-of-plane rigidity of the steel plate, so it is possible to avoid concrete It is possible to prevent protrusion during pouring.

る。Table 1 Concrete used in the test On the other hand, compared to a conventional structure in which a steel plate without protrusions and a shaped steel member are joined and concrete is poured, even if shear force occurs at the interface between the steel plate and concrete, the rhombus Since it has sufficient adhesion strength due to the continuous eye-shaped protrusions, it is possible to prevent cracks from occurring in the concrete due to displacement.
（実施例） 次に図面に従って実施例について説明する。(Example) Next, embodiments will be described according to the drawings.

とコンクリートとが一体化した合成構造となっている。FIG. 1 shows a T-shaped steel member 2 joined over its entire length by welding onto a steel plate l having diamond-shaped continuous protrusions 6 shown in FIG. As shown in the figure, by burying the shaped steel member 2 in the concrete 3, a composite structure in which the steel plate and concrete are integrated is obtained.

も得られる。Furthermore, the web portion 4 of the shaped steel member 2 is not of the light layer type shown in FIG. 1, but is partially cuffed as shown in the schematic side view of FIG. In the case of a non-filled type or a truss type, the web portion 4 may be of a non-filled type or a truss type made of folded plates or reinforcing bars 7 as shown in the same schematic side view in FIG. Because the concrete flows through the cut part, the filling of concrete around the shaped steel member becomes more reliable compared to the optical layer type, resulting in improved workability and crack resistance.

Since the spread angle α of the bearing pressure reaction force 6 due to the flange portion 5 can be expected to have a spread of approximately 30″, the distance l from the end of the flange portion to the end of the adjacent flange portion is k, assuming that the height of the web portion is h. It is desirable that ≦3h.
