[Prior Art] A steel/concrete composite structure has, for example, a protrusion provided on the surface of a Η-shaped steel, and a concrete is attached around the Η-shaped steel. In the Η-shaped steel in which the projections are attached, it is known that a projection is provided on the inner surface of the flange (for example, Japanese Patent Laid-Open Publication No. Hei. No. Hei. On the other hand, a wall body using _ steel as a core material has an SRC wall body using a Η-shaped steel 101 as shown in Fig. 27 . The wall system shown in FIG. 27 has a transverse reinforcing bar 1 0 4 which is laid in the lateral direction on the sides of the concrete 1 0 3 ; and a main reinforcing bar which is laid in the longitudinal direction with respect to the transverse 'reinforcing bar 1 0 4 105; and the Η-shaped steel 101 is disposed at the central portion of the wall body. In the wall body, the concrete 1 0 3 , the transverse reinforcing bar 104 and the main reinforcing bar 1 0 5 are integrated to form a steel/concrete structure, but the adhesion of the Η1 1 1 and the concrete 1 0 3 does not fall off. The integration of Η1100 1 and concrete 1 0 3 SUMMARY OF THE INVENTION In the above Patent Document 1, in order to increase the bonding force with concrete, it is preferable to provide a projection on the inner surface of the Η-shaped steel. However, it is preferable to provide a projection and how to arrange it so as to improve the adhesion of concrete. There is no disclosure of force. In fact, according to research by the inventors, it is known that even if a protrusion is provided in the surface of the steel, sufficient adhesion cannot be obtained due to the size and arrangement of the protrusion. 6 312 / invention specification (supplement) / 93-05/93107251 1271465 force Happening. Here, a first object of the present invention is to obtain a steel which is excellent in adhesion to concrete by the size and arrangement of specific projections. In addition, in the wall body shown in Fig. 27, between the horizontal reinforcing bar 104 and the main reinforcing bar 1 0 5 and the concrete 1 0 3, a steel-concrete composite structure is formed, which is mainly in the horizontal reinforcing bar 104 and the main A certain amount of concrete 1 0 3 is placed around the steel bar 1 0 5 . Therefore, the distance of B 1 0 shown in Fig. 27 is necessary to be a certain amount, and as a result, there is a problem that the thickness A1 0 of the wall body is increased. In recent years, in the field of civil engineering and construction, in order to expand the area that can be effectively utilized, there is a tendency to develop the wall of the underground wall and the structural wall of the building. However, in the wall body as shown in Fig. 27, It is difficult to maintain the endurance of the wall while reducing the wall thickness. Here, a second object of the present invention is to obtain a wall body which can reduce the wall thickness. (1) In order to increase the adhesion to the steel, the steel of the present invention has a plurality of protrusions on the inner surface side, and is characterized by: a width b2 of the upper side of the protrusion perpendicular to the cross section of the profile forming the protrusion, and a protrusion height h, a protrusion The pitch P satisfies the following formula. Ρ/hSlO, and P/b2^4 Hereinafter, the basis of the above formula will be described. First, the description will be made on the basis of P / h S 1 0 , and the basis of P / b 2 g 4 will be described next. (A) P / h S 1 0 shows an example of a cross section perpendicular to the profiled steel surface forming the protrusion according to Figs. 18(a) and 18(b), and Fig. 18 (a) shows a protrusion of a trapezoidal cross section, Fig. 1 8 ( b ) A protrusion showing a rectangular section. 312/Invention Manual (Repair)/93-05/93107251 1271465 In the steel and concrete structure, it is indispensable to achieve high endurance and high rigidity, and the two are integrated to obtain steel and concrete. A structure that balances the external force. The integration of steel and concrete means the structure of stress exchange between steel and concrete, so there is sufficient adhesion between steel and concrete (performance appears to be necessary. Attachment of the above-mentioned profiled steel to concrete) The force is generated by the engagement of the protrusion formed on the inner surface of the section steel with the concrete, which depends on the pressure of the concrete to break the ri or the shear failure 7: 2. Here, the pressure breakdown r! refers to the front of the protrusion The shear strength determined by the compression failure of the concrete, and the shear failure r 2 is the shear strength determined by the shear failure of the joint between the protrusion and the concrete. If the general formula indicates the pressure damage r When I and shear destroy r 2 , it becomes the following formula: hx Lx ac hx ac /1λ r, =-L =....................... ........(I)

According to this, it is necessary to obtain the adhesion stress of 1: max for the condition for increasing the adhesion strength by δ inch. In order to obtain the adhesion stress r max , it is necessary to compare τ i and τ 2 , and the following assumptions are made for this. (Hypothesis 1) The axial compressive strength σ c and the shear strength r of the concrete generally used as building materials. The relationship is assumed to be of the following formula (also approximated to the design basis, etc.). τ c = 0 . lx ac -------------------(3) If the relationship between τ !, τ 2 and P/h is displayed based on the above assumption, Figure 19. The smaller of the two failure modes becomes the adhesion stress τ ma X between steel and concrete, but from the above curve, it is shown that P / h = 1 0 is the boundary, and in the following areas, the concrete is broken into shears. The form of failure (depending on r 2) does not change much with respect to 7: max. On the other hand, when it is more than this, concrete failure becomes a form of partial pressure failure (depending on r !), and the decrease in r max becomes remarkable. . Therefore, in order to secure a large adhesion, it is preferable to cause the concrete to be broken into a region in the form of shear failure. Here, in consideration of the error in the relationship between the one-axis compressive strength σ e of the concrete and the shear strength r c , the protrusion pitch at which the stable adhesion stress r max can be obtained satisfies the following equation.

In general, the greater the proportion of concrete on the above-mentioned boundary line (i.e., the smaller the proportion of the upper side b 2 ), the higher the shear strength. The ratio of the protrusion pitch P to the upper edge width b2 of the protrusion and the influence of the shear strength 7:2 between the steel and the concrete can be evaluated by the following formula. τ 2=(P- b2)/ P · rc -------------(5) t: c : shear strength of concrete (5) The performance of the system is considered to depend on the width of the upper edge of the protrusion b The shear strength τ 2 of the strength loss of the length loss of the concrete shearing failure surface is 2, and the concrete shear strength re is multiplied by the shear failure surface length loss rate (Ρ - b2) / P is expressed as r 2 . If the formula (5) is shifted to the left, it becomes 7:2/7: (:=(?- b 2)/ Ρ, and the relationship curve becomes the graph 2 1. According to Fig. 21, it can be seen that in P In the region where /b2 is less than 4, the shearing strength τ 2 drops sharply. In addition, Fig. 2 shows the relationship between the rate of change of the fractional change (first-order differential) of r 2 / rc and P / b 2 . In the case where P / b 2 is 4 or more, the rate of change of the addition is saturated. According to the above, it is necessary to satisfy the following equation in order to maintain the relationship between the protrusion pitch P of the stable adhesion stress and the width b 2 of the protrusion. P/b2 ^ 4 - (6) (2) The profile steel of the present invention has a plurality of protrusions on the inner surface side, and is characterized by being perpendicular to the upper side of the protrusion on the section of the profile steel surface forming the protrusion The width b2, the protrusion height h, and the protrusion pitch P satisfy the following formula: 2 mm $ h $ 50 mm, and 4b2 SPS 1 Oh 10 312 / invention specification (supplement) / 93-05/93107251 1271465 The protrusion height h is set in the above range The reason is as follows. If the height of the protrusion is less than 2 mm, the concrete is laid in the water like a underground wall, by the impurity pair called slime (s 1 ime ) It is difficult to ensure adhesion to the concrete, such as corrosion of adhesion or protrusions, and therefore 2 mm is set as the lower limit. On the other hand, if the height of the protrusion exceeds 50 mm, there is a concern that the perfusion catheter is inserted or pulled up. In the case of rolling, it is preferable to set the upper limit of the height of the protrusion to 5 mm. This is because the height of the protrusion of '5 mm or more is formed by rolling, and the rolling is excessively large. It is necessary to make the load, and it is not economical. In addition, in the case of attaching the protrusion by welding of a bar steel, an angle material, etc., it is preferable to set the lower limit of the protrusion height to 9 mm. This is because if the protrusion height is less than 9 mm, the welding is performed. The reason why the installation work is complicated and the number of installations is large is unrealistic. Moreover, 4b2 SPS 1 Oh, which defines the range of the projection pitch P, is divided into two equations and is Ρ/hS10 and P/b2. ^4. Thus, the relationship specified by the relationship is as described in the above (1). (3) The profile steel of the present invention has a plurality of protrusions on the inner surface side, which is characterized by being perpendicular to the profile steel surface forming the protrusions. In the cross section, the width bi of the lower side of the protrusion, the height h of the protrusion h, and the pitch P of the protrusion satisfy the following expression. 2 mm ShS 50 mm and 41 m SPS 1 Oh In the above relationship, the reason for the 4 b! SP is as follows. The relationship between the width b2 and the width of the lower edge 13! is preferably set to 1 S b! / b 2. If so set, the lower limit of b! / b 2 becomes 1. Here, 11 312 / invention specification (repair) ) /93-05/93107251 1271465 The protrusion width b2 of 4b2$P of the above (2) is replaced by the width b! of the protrusion lower side, and the width b2 of the protrusion of the above (2) is replaced by the protrusion degree b2 of the protrusion, that is, 4biSP . Further, in the case where the projection cross section is a rectangle as shown in Fig. 18(b), b 2 = b 1 = b °, and the projections may be formed by rolling or the like. However, in this case, the profile or the like does not have to be Figure 1 8 (a), Figure 18 (b) shows the ideal trapezoidal i shape. For example, as shown in Fig. 23, the protrusions are slightly triangular in shape in the direction of the front end, and the cross-sectional shape is different depending on the case. In such a case, the conditional expression of the present invention shown in (1) to (3) may be described as long as the design representative value is evaluated. For example, in the example of Fig. 23, it is only necessary to design a representative value as follows (refer to Fig. 24). (A) protrusion height h: a value from the root of the protrusion (ventral side) to a point of 1 / 2 L (L: length of the protrusion (distance from the root of the protrusion to the front end of the protrusion)) (B) width of the protrusion b 1 : from the root of the protrusion ( Value of the ventral side to 1 / 2 L point (C) protrusion width b 2 : value from the root of the protrusion (ventral side) to the point of 1 / 2 L (D) protrusion pitch P: from the root of the protrusion (ventral side) The distance between the center position (width direction) of the 1 / 2 L location, and the value from the base of the protrusion (ventral side) to the lower side of the 1 / 2 L point, is the height h of the height of the h, because the concrete and steel at the location The effective area (the projected area of the side surface of the protrusion) is in the shape of a square. W2/Invention (Supplement)/93_〇5/931〇7251 The upper side of the wide surface is also changed from the moment of change. The reason for the damage of 12 concrete of 12 concretes such as the top of the south side of the south is raised. In addition, regarding the protrusion widths bl, b2 and the protrusion pitch P, because the root portion (ventral side) of the protrusion is at a position of 1 / 2 L, the effective mixed shear length of the concrete and the steel material (the length of the concrete between the adjacent protrusions) is square. The reason why the conditions become equal. (4) The profile steel of the present invention is a section steel in which the ventral surfaces face each other and is plurally established in the wall-direction, and is used as a structural material of the steel/concrete wall body, and has a feature in which the inner surface side of the flange has a plurality of The protrusions are perpendicular to the upper portion b2, the protrusion height h, and the protrusion pitch 该 of the protrusions on the cross section of the Η-shaped steel surface on which the protrusions are formed, and satisfy the following formula. P/hS40, P / b 2 ^ 4 The basis for setting P / b 2 - 4 in the numerical value limitation of the above formula is as described above (1: Ming. Hereinafter, the basis of P / h S 4 0 will be described. The adhesion stress degree τ between the steel-concrete according to the protrusion of the Η-shaped steel is defined as two in comparison with the strength (r !) when the concrete is crushed and the strength (r '2 ) when the concrete shear _ bad form If the numerical value is represented by a general formula and ri and 7:2, it is as described above.

示附設突起Η型鋼1用作為構造材的壁體,顯示僅附設突 起Η型鋼1用作為構造材(參照圖4 (a )),除附設突起Η型 鋼1外還將橫鋼筋4作為構造材(參照圖4 ( b )),進一步將 縱鋼筋5作為構造材(參照圖4 ( c ))。 在圖4 ( a)所示壁體中,附設突起Η型鋼1與混凝土或固 化處理土之間的附著力優良,因此將Η型鋼1與混凝土或 固化處理土 一體化,構成拉伸力主要由鋼負擔,壓縮力主 要由混凝土等負擔的鋼·混凝土構造。 其結果,在Η型鋼與混凝土間無法取得附著的習知例的 情況(參照圖2 7 ),有在與鋼筋1 0 4、1 0 5之間獲得附著而 20 312/發明說明書(補件)/93-05/93107251 1271465 作為鋼·混凝土構造的必要,但在本實施形態中,為取得 與混凝土等的附著,無配置鋼筋1 0 4、1 0 5,或於此等周圍 配置指定厚度以上的混凝土的必要。而且,因為突起形成 於凸緣的内面侧,因此於凸緣外面不需要取得與Η型鋼1 的附著用的混凝土等。 其結果,可將從附設突起Η型鋼1的凸緣外面至壁面的 間隔Β 1,設為較從習知例之凸緣外面至壁面的間隔Β 1 0 小,可減薄壁厚。 另外,構造體本身的耐力增加,因此其亦意味著可減薄 壁厚。 另外,因為本實施形態之壁體係使腹面面對來配置Η型

of the concrete is from the concrete, the width is wide, and the ax ’ is broken. In the area under the lower type 13 1271465, concrete failure becomes a form of shear failure (depending on τ 2), and there is no large change in r, max. On the other hand, if it is more than this, concrete failure becomes a pressure. The form of destruction (depending on τ !), the drop in τ 'max becomes significant. Therefore, in order to secure a large adhesion, it is preferable to determine the protrusion pitch in such a manner that the concrete is broken and formed in a region in which the fracture is broken. According to this relationship, in consideration of the error in the relationship between the one-axis compressive strength σ e of the concrete and the shear strength re, as the shape of the protrusion pitch at which the stable adhesion stress degree 7: ' ma X can be obtained, it is set to P / h S 4 0. (5) The profile steel of the present invention is a Η-shaped profile steel which is formed in the longitudinal direction of the wall body so that the ventral surfaces face each other and is used as a structural material of the steel/concrete wall body, and is characterized in that it is on the inner side of the flange The plurality of protrusions are provided, and the upper side width b2, the protrusion height h, and the protrusion pitch Ρ of the protrusion perpendicular to the Η-shaped steel surface section forming the protrusion satisfy the following formula. The reason why the protrusion height h is 2 mmSh$50 mm in 2 mm ShS 50 mm and 4b2 S P S 40h is as described in the above (2). Further, when 4 b 2 S P S 4 0 h in the range of the projection pitch P is defined, when this is decomposed into two equations, P / h S 4 0 and P / b 2 ^4 are obtained. Therefore, the basis of the P/hS 40 is as described in the above (4). The basis of P/b2 ^ 4 is as described in (1) above. (6) The profile steel of the present invention is a Η-shaped profile steel which is formed in the longitudinal direction of the wall body so that the ventral surfaces face each other and is used as a structural material of the steel/concrete wall body, and is characterized in that it is on the inner side of the flange The plurality of protrusions are provided, and the lower side width b!, the protrusion height h, and the protrusion pitch Ρ of the protrusion perpendicular to the Η-shaped steel surface section forming the protrusion satisfy the following formula. 2mmShS50mm, 15 312/invention specification (supplement)/93-05/93107251 1271465 and WSPSdOh The reason why the protrusion height h is 2 mm$hS50 mm is as described in the above (2). Further, the above-mentioned (5) protrusion upper side width b 2 is replaced by the protrusion lower side width b!, and the substitution is based on the description of (3) above. (7) The steel according to the above aspect (1) to (6) is characterized in that an adhesion reinforcing mechanism is provided on the ventral surface. As the adhesion reinforcing mechanism provided on the ventral surface, it may be a protrusion or a concave portion. In the case of the protrusion, the condition shown in the above (1) to (6) may be satisfied, or it may be unsatisfactory. In either case, by providing an adhesion reinforcing mechanism on the ventral surface of the adhesion reinforcing mechanism, the protrusions provided in the above (1) to (6) can be assisted to improve the adhesion. (8) The steel according to the above aspect (1) to (7) is characterized in that h_tn is obtained when the width of the lower side of the protrusion is 1^. The setting is because if the width In of the lower side of the projection is too narrow, the projection is deformed to reduce the slip-resistance effect of the concrete, and at least the projection height h or more is set. Further, although the above description is directed to the width b of the lower side of the projection, if the width b 2 of the projection is too wide, the shearing area of the concrete is reduced (the shear stress is reduced), and therefore, there is a limit. necessary. However, with respect to this point, the above-mentioned (2) restriction formula for preventing the fall of the shear stress τ 2 has been set to 4 b 2 S Ρ, and therefore there is no need to add it. (9) The steel according to the above aspect (1) to (8), wherein the protrusion is provided on the inner surface and the ventral surface of the flange, and is provided in the specification of the invention. ) /93-05/93107251 1271465 and other two-sided protrusions are integrated. (10) The wall according to any one of the above (1) to (9) is used as a structural material, characterized in that the steel profile faces the outer surface of the flange facing the wall surface along the length of the wall body. The direction is set up in multiples. (11) Further, in the wall body of the above (10), the adjacent steel profiles are connected to each other by a connecting member. (1 2) Further, in the wall body of the above (10), it is characterized in that a transverse reinforcing bar is disposed on a plurality of portions which are in contact with the outer surface of the flange of the steel and in the height direction of the wall. (1 3) Further, in the wall body of the above (1 2), it is characterized in that, between the flanges of the adjacent steel profiles, the inner side of the transverse reinforcing bar is in contact with the horizontal reinforcing bar, and the cross is formed in a cross shape. Set the main reinforcement. (1) Further, in the wall body of the above (1 2) or (1 3), the transverse reinforcing bar is fixed to the outside of the flange of the steel. [Embodiment] (Embodiment 1) Fig. 1 (a) and Fig. 1 (b) are explanatory views of a projection Η section steel 1 according to Embodiment 1 of the present invention, and Fig. 1 (a) is a schematic plan view, Fig. 1 (b) ) is a partial section view taken along line XX. As shown in Fig. 1 (a) and Fig. 1 (b), the projection Η steel 1 of the first embodiment is formed on the four faces of the inner surface of the flange, and a plurality of projections having a rectangular cross section are formed along a plurality of portions in the longitudinal direction of the Η-shaped steel. The longitudinal direction of the projection is configured as the flange width Wf direction. The projection 2 on the inner surface of the flange has a projection height hi, a projection width b, and a projection length L1, and is formed so as not to come into contact with a corner portion formed by the flange and the abdomen. 17 312/Invention Manual (Supplement)/93-05/93107251 1271465 For the shape and arrangement of the protrusions, in order to increase the adhesion to the coagulation, the protrusion pitch P is set to 4 b S P degrees hi is 2 mm $ hlS 50 mm. Further, the protrusion 2 is oriented in a direction parallel to the flange width Wf direction. When the projections 2 are parallel to the width direction of the flange, the adhesion characteristics to the right and left are the same, and there is no difference in strength and weakness, so performance is exhibited. On the other hand, if the direction of the protrusion is inclined obliquely, the characteristics may be obtained by roll forming depending on the direction of the attached movement, and although it has a shape, the difference in characteristics depending on the attachment direction is extremely small. (Embodiment 2) Fig. 2 (a) and Fig. 2 (b) are explanatory views of a steel 1 1 according to an embodiment of the present invention, and Fig. 2 (a) is a partial cross-sectional view taken along line Y-Y of a schematic plan view. In the second embodiment, the projections of the truss steel 1 1 have a rectangular protrusion 2 on the inner surface of the inner surface of the rim and the protrusion 2 of the first embodiment, and the adhesion is strengthened on both surfaces of the abdomen along the length of the bismuth steel. The protrusions 2 that form the ventral surface in the longitudinal direction of the protrusion as the abdomen height direction are respectively formed on the abdomen two degrees h2, the protrusion width b, and the protrusion length L2, and the protrusions 2A on the inner surface of the flange are formed so as not to contact the flange and the abdomen. · Department. Further, the protrusion high shoulder and the protrusion length L2 of the protrusion 2A formed in the abdomen® can be formed with respect to the inner surface of the flange 312/invention specification (supplement)/93-05/93107251 soil or solidified soil S 40hl, and the protrusion is high. The attached protrusion 形 of the shape 2 having a difference in the width direction of the attachment edge formed in the direction in which either side of the protrusion is long is formed, and FIG. 2( b ) is a projection along the 丨 2 The cross section is formed in the same shape as a plurality of partial projections 2 A, and the projections 2 having the projections on the high surface and the angle L h2 formed by the abdomen and the protrusion width b are independently determined. 18 1271465 The shape and arrangement of the protrusions formed on the ventral surface are preferably set to satisfy the protrusion pitch P of 4bSP$40h2 and the protrusion height h2 as in the first embodiment, in order to increase the adhesion to the concrete or the cured soil. 2mm Sh2S50mmo Originally, as long as the adhesion necessary for the protrusion formed on the flange face can be ensured, the protrusion formed on the ventral surface is only used to increase the auxiliary adhesion, and in this case, it is not necessary to satisfy the above-mentioned Shape and configuration. (Embodiment 3) Fig. 3 is a schematic plan view showing a projecting Η-shaped steel 21 according to Embodiment 3 of the present invention. As shown in Fig. 3, the projecting projection Η steel 2 1 of the third embodiment has projections 2 having a projection height hi, a projection width b, and a projection length L1 on the four faces of the inner surface of the flange, and at the same time, a projection height h2 is formed on the ventral surface. A protrusion 2B having a protrusion width b and a protrusion length L3. Further, the projection 2 on the inner surface of the flange and the projection 2B on the ventral surface are formed to be in contact with the corner portion formed by the flange and the abdomen, and the projection 2B on the ventral surface is not formed at the central portion of the ventral surface. By the contact of the above-mentioned corners, the adhesion to the concrete or the solidified soil can be further increased (integration effect). The projection length L3 of the projection 2B formed on the ventral surface of the Η-shaped steel 21 is set to be shorter than the projection length L2 of the projection 2 形成 formed by the ventral surface of the projection Η-shaped steel 11 attached in the second embodiment. Further, the shape and arrangement of the projections, i.e., the projection pitch Ρ, the projection width b, and the projection heights h 1 and h 2 are the same as those of the first and second embodiments. The above-mentioned Embodiments 1 to 3 are provided with the protrusions Η1, 1, 1 and 2, and 19 1912/Invention (Supplement)/93-05/93107251 1271465, the protrusion 2 is such that the protrusion length direction and the flange width are In the case where the directions are parallel, the projections of the projecting Η-shaped steel of the present invention can obtain a certain adhesion even if the projections 2 are formed to be inclined with respect to the flange width direction. The reason is as described above. Further, the method of forming the projections 2 of the first embodiment on the inner surface of the flange may be formed by rolling, or may be cut to a predetermined length by using a projecting member such as an angle member, a round bar, a profiled bar, or a stud. It is fixed to the inner surface of the flange. In the case where the projections 2 are formed by the projecting members, it is preferable to easily fix the steel projecting members. The protrusions 2Α and 2Β can also be formed in the same manner as the protrusions 2. (Fourth Embodiment) Fig. 4 is an explanatory view showing a wall body according to a fourth embodiment of the present invention, and shows a horizontal cross section of a case where a wall body is erected. As shown in Fig. 4, the wall body according to the fourth embodiment is a wall body in which the projecting Η-shaped steel 1 shown in the first embodiment is used as a structural material, and it is shown that only the projecting Η-shaped steel 1 is used as a structural material (see Fig. 4 (refer to Fig. 4 ( a)) In addition to the protruding Η steel 1, the horizontal reinforcing bars 4 are used as the structural members (see Fig. 4 (b)), and the vertical reinforcing bars 5 are further used as the structural members (see Fig. 4 (c)). In the wall body shown in Fig. 4 (a), the adhesion between the protruding Η-shaped steel 1 and the concrete or the solidified treated soil is excellent, so the Η-shaped steel 1 is integrated with the concrete or the solidified treated soil, and the tensile force is mainly composed of Steel load, compressive force is mainly composed of steel and concrete that is burdened by concrete. As a result, in the case of a conventional example in which adhesion between the steel and the concrete is not obtained (see Fig. 27), adhesion is obtained between the steel bars 1 0 4 and 1 0 5 and 20 312 / invention specification (supplement) /93-05/93107251 1271465 It is necessary for the steel/concrete structure. However, in the present embodiment, in order to obtain adhesion to concrete or the like, the reinforcing bars 1 0 4 and 1 0 5 are not disposed, or the surrounding thickness is specified or more. The necessity of concrete. Further, since the projection is formed on the inner surface side of the flange, it is not necessary to obtain concrete or the like for adhering to the Η-shaped steel 1 on the outer surface of the flange. As a result, the gap Β1 from the outer surface of the flange of the protruding Η-shaped steel 1 to the wall surface can be made smaller than the interval Β 10 from the outer surface of the flange of the conventional example to the wall surface, and the thickness can be reduced. In addition, the endurance of the structure itself is increased, so it also means that the wall thickness can be reduced. Further, since the wall system of the present embodiment has the Η-shaped steel 1 disposed on the ventral surface, it is expected that the concrete restraining effect between the flanges of the bismuth steels 1 is over the entire length of the wall width, and the adhesion can be further improved. In other words, as shown in Fig. 5 (a), in the case where there is nothing in the vicinity of the Η-shaped steel 1, cracks occur in the concrete, and the concrete bounded between the flanges is separated in the left-right direction in the figure. Reduce adhesion. On the other hand, as shown in Fig. 5 (b), when the Η-shaped steel 1 is placed facing each other with the ventral surface facing each other, when the concrete sandwiched by the flanges of the respective Η-shaped steels 1 is to be separated, the adjacent portions are restrained from each other to prevent this. Therefore, the adhesion can be maintained, and the endurance of the wall body can be prevented from being lowered. The maximum adhesion stress r ' m ( N / mm 2 ) to the concrete in which the wall of the raised Η steel 1 is attached, and the flanges are not restrained (that is, when one of the protruding steels is attached), Become 2. 7~2 5 times. In addition, in the wall body in which the projecting Η-shaped steel 1 is used as the structural material, if the interval between the centers of the adjacent protruding Η-shaped steels 1 is excessively opened, 21 312/invention specification (supplement)/93-05/ 93107251 1271465 Extremely low endurance and rigidity, for example, there is concern about the occurrence of a blow (a type of brittle failure) on the underground wall, and at the same time, the wall thickness is reduced. Here, the center of the adjacent projecting Η-shaped steel 1 is preferably set to have a flange width of 2.5 times in accordance with the force applied to the wall body. In addition, in the case of constructing a subterranean wall, it is possible to insert a pipe inserted in the adjoining zone (referred to as a perfusion pipe (generally, the diameter is: 2 0 0~ sub, on the other hand, in order to achieve sufficient thinning, it is preferable to smash the steel) The height of the abdomen of 1 is 600 mm or more, and the width of the flange is more than 3 1 5 N / m m2. Next, the wall structure of Fig. 4 (b) is explained. The wall system touches the attached truss steel 1 The outer side of the flange is provided with a horizontal reinforcing bar 4 at a high portion of the wall body. In the case shown in Fig. 4 (b), the resistance of the wall body to the bending of the transverse reinforcing bar 4 is perpendicular. Further, in Fig. 4 ( b) In the wall structure, the transverse reinforcement 4 is the auxiliary I as shown in Fig. 27, and the interval B2 from the outer surface of the flange to the wall surface can be reduced as compared with the case where the concrete 1 0 3 and the reinforcement 10 must be present. The wall structure of Fig. 4 (c) will be explained. The wall system, like the steel bar 4, is also in contact with the inner side of the flange transverse reinforcement 4 to which the adjacent projecting profile steel 1 is attached, and at the same time, the cross-shaped reinforcing bars 5 are crossed. In the wall body, resistance against bending of the wall body and the main steel direction can be increased.

根據上述實施例1〜3驗證了可對沖壓力確保指定的附 著強度的情況。 但是,對實際之壁體具有卓越的作用力,係彎曲、剪斷 力,因此,在僅對沖壓力的性能驗證上,要作為壁體的性 能驗證可以說不夠充分。 在此,本實施例中藉由實際大小尺寸的試驗體來確認 鋼·混凝土壁體對彎曲、剪斷力的性能。 圖1 6為本實施例之試驗體裝置的說明圖,係將Η型鋼1 配置於中心部,由混凝土 3 1包圍在其周圍的構造。其設為

addition, in the wall body, the main reinforcing bar 5 is disposed in the transverse steel I 312 / invention description patching) /93-05/93107251 The effect of the concrete is also reduced by the interval, the 1.0. For the tube of 250 mm), the attachment protrusion Wf is 300 mm. The above-mentioned attachment direction is increased by a plurality of joints, and the outer side of the vertical δ 4 of the main rib 5 is arranged in addition to the transverse direction. 22 1271465 Therefore, by arranging the main reinforcing bars 5, the gap B3 from the outer surface of the flange to the wall surface is not increased, and the entire wall thickness can be formed into a thin wall. Further, in the wall body of the fourth embodiment, in the case of the member wall body, the construction accuracy of the Η-shaped steel member can be improved by connecting the adjacent projecting Η-shaped steels 1 to each other. For example, in the wall structure shown in Fig. 4 (a), for example, flat steel is used as the continuous structural member, and in the case of the member wall, the flat steel is fixed by welding to the flange of the projecting Η-shaped steel 1 by welding. The wall body in which the adjacent Η-shaped steels 1 are connected to each other is fixed to the flat steel to which the projecting Η-shaped steel 1 is attached. Further, in the wall structure shown in FIGS. 4(b) and 4(c), in the case of the member wall body, the transverse steel bar 4 is welded to the flange surface, so that the steel plate structure portion can be connected to the adjacent steel section 1 Walls made of each other. In the wall body in which the adjacent steel profiles 1 are connected to each other by the joint structural member or the transverse steel bars 4, even if the force acts unevenly in the longitudinal direction of the wall body, for example, the earth pressure is applied to the underground wall. By connecting the structural members to the lateral direction, the force can be directed to the ventral surface of the adjacent protruding Η-shaped steel 1, and the restraining force of the concrete sandwiched in the flange surface can be further enhanced. Further, as the transverse reinforcing bars 4 and the main reinforcing bars 5, it is preferable to use a suitable profiled reinforcing bar to increase the adhesion to concrete or the like. Further, in the above-described fourth embodiment, the projecting Η-shaped steel 1 shown in the first embodiment is exemplified, but of course, the Η-shaped steels 1 1 and 2 1 shown in the second and third embodiments may be used as the structural members to form the wall. body. Then, in the case where the slab steels 1 1 and 2 1 shown in the second and third embodiments are used as the structural members to form the wall body, the Η-shaped steels 1 1 and 2 1 and the concrete and the like 23 312 / invention manual (supplement) /93-05/93107251 1271465 The steel angle material is welded to the Η-shaped steel as a protruding member. Further, at the time of the test, the steel jig was used to sandwich the concrete surface on both sides from both sides and was restrained. Load the load on each of the obtained test bodies in the direction indicated by the arrow in Fig. 7, and detect the relative offset at this time, and take the relative offset (mm) on the horizontal axis, and take it on the vertical axis. The adhesion stress τ (N / mm 2) is shown in Fig. 8. The adhesion stress r (N / m m2) is the value of the load minus the sum of the areas of the flanges in contact with the concrete SUM (SUM = (300-12) χ 500 χ 2 = 288000 mm 2 ). The load method is performed by controlling the stamping monotonic load by displacement. In addition, Table 1 collectively shows the maximum adhesion stress Γ ' ma X of each of the above test bodies, the maximum adhesion stress Γ ' 111 a X of each test body, and the ratio of the maximum adhesion stress Γ \ ax of the test body 1 and the maximum load. The relative offset of the time. Further, the allowable value of the relative offset between the steel and the concrete in the case of the steel/concrete wall is assumed to be 5 m m, and therefore the range is compared.

The maximum adhesion stress becomes extremely large. The adhesion strength originally required as the wall structure is 3.0 N / m m2, but in the test body 2 (protrusion pitch P = 5 0 in in ) and the test body 3 (protrusion pitch P 2 100 mm), It is more than 3 · 0 N / m m2, but in the test body 4 (protrusion 25 312 / invention manual (supplement) / 93-05/93107251 1271465 distance P = 150mm), the maximum adhesion stress is less than 3.0 N /mm2. From this fact, it is understood that in order to secure the necessary adhesion strength as the wall structure, it is necessary to satisfy P/hS40 and P/b^4 in the range of the present invention. Namely, by using the projecting Η-shaped steel 1 attached to the inner surface of the flange having the projections in the range of the present invention, a wall body having high endurance and high rigidity can be obtained, and the wall body can be made thinner. (Example 2) The same experiment as in Example 1 was carried out in order to investigate the adhesion characteristics of the rolled formed projections (see Fig. 11 (a), Fig. 1 1 (b) and Fig. 24). In the present embodiment, the comparative example in which the present invention is a test body 5, 9, and 10, and the influence of the verification protrusion pitch is the test body 6, and the comparative example for influencing the influence of the height of the test protrusion is the test body. 7. An example of the present invention for influencing the influence of the direction of the protrusion is the test body 8. Further, at the time of the test, a steel jig was used in the same manner as in the first embodiment, and the concrete surface on the side was sandwiched from both sides to be restrained.

The relationship between the velocity (N/mm2) and the relative offset (mm) 26 312/invention specification (supplement)/93-05/93107251 1271465. It can be seen from Fig. 9 that the maximum offset within the relative offset δ = 5 mm The degree of stress is much greater than that required for the wall structure in the test body 5 (protrusion pitch P = 5 0 Hi m ) The adhesion strength is 3.0 N / m m2, but in the test body 6 (protrusion pitch P = 150 mm), the maximum adhesion stress is less than 3 · 0 N / m m2. From this, it can be known that during rolling When the protrusions are formed, the protrusion pitch P is set to P / h S 4 0, which is effective for obtaining the adhesion strength necessary for the wall structure. (2) The influence of the protrusion height h is considered to examine the influence of the protrusion height. Fig. 10 shows the relationship between the adhesion stress (N / mm2) and the relative offset (mm) of the test body 1, the test body 5, and the test body 7. From Fig. 10, the relative offset (5 = The maximum adhesion stress within 5 mm, in the test body 5 (protrusion height h = 3 ni m ), greatly exceeds the adhesion strength required for the wall structure of 3.0 N / m m2, but in the test body 7 (In the protrusion height h=1.2mn〇, the maximum adhesion stress is less than 3.0 N/mm2. In addition, regarding the test body 9 (protrusion height h = 2 n) m), the test body 10 (protrusion height h = 2.5) Ni in ), as shown in Table 2, the maximum adhesion should be 3. 9 5 N / m m2, 4. 0 1 N / m m2, exceeding the wall structure The adhesive strength to 3 · 0 N / m m2 square from the above results, the protrusion height h to obtain a specified adhesion strength used, preferably within the range of the present invention (P / h S 4 0). (:3) Examination of the influence of the protrusion direction (curved shape) in the case of setting the protrusion of the curved shape shown in Fig. 11 (a) and Fig. 1 1 (b) 27 312 / invention specification (supplement) / 93- 05/93107251 1271465 Simulated wall, tested by repeated loads in the direction indicated by the arrows in the application diagram. As a result, as shown in Fig. 15, a simulated wall body in which a projection Η-shaped steel is attached to the inner surface of the flange having the projections in the range of the present invention on the inner surface of the flange, the maximum load of the displacement of the load point position, and the use thereof are shown. The maximum load of the simulated wall of the non-protrusive Η steel is compared with a value of 1.3 times or more, and it is known that it has high endurance. Further, the rigidity of the dummy wall body in which the inner surface of the flange having the inner surface of the flange having the projections in the range of the present invention is provided with the projection Η-shaped steel is also 1.3 times or more the rigidity of the dummy wall using the non-protrusion Η-shaped steel. . (Embodiment 4) According to the above-described Embodiments 1 to 3, the case where the specified adhesion strength can be ensured by the hedging pressure is verified. However, it has excellent force on the actual wall body, which is bending and shearing force. Therefore, it is not sufficient to verify the performance of the wall as a performance verification of the punching pressure alone. Here, in the present embodiment, the performance of the steel and concrete wall body against bending and shearing force was confirmed by the test body of the actual size. Fig. 16 is an explanatory view of the test body device of the present embodiment, which is a structure in which the Η-shaped steel 1 is disposed at the center portion and surrounded by the concrete 3 1 . It is a structure in which the protective plate 3 3 for protecting the concrete 3 1 is provided at both ends of the test body and the center portion in the axial direction, and is supported at the center portion in the axial direction while supporting both end portions. Further, the specifications of the Η-shaped steel were the same as those of the first embodiment, and the specifications (including the production method and dimensions) of the projections and the specifications of the concrete were the same as those of the test body 5 of the second embodiment. The performance to be possessed as a steel/concrete wall body is obtained by performing calculation based on analysis of 29 312/invention specification (supplement)/93-05/93107251 1271465 F E 。. Moreover, as an analytical specimen, the mechanical properties of the concrete and the Η-shaped steel of the test specimen are determined by the stress-deformation curve (non-linear curve) obtained from the test results of the respective elements, and at the same time, in the concrete and the Η-shaped steel. At the interface, the adhesion characteristics were standardized using the interface elements according to the stamping adhesion test. The test was performed to determine the deflection of the load point when the test body shown in Fig. 16 was loaded on the center portion thereof. Figure 17 is a graph showing the results of this test, with the horizontal axis showing the deflection of the load point (m m ) and the vertical axis showing the load (k Ν ). As can be seen from Fig. 17, the experimental results are in good agreement with the calculated values considering the adhesion characteristics. Therefore, it has been confirmed that the bending and shearing forces have properties expected as steel and concrete walls. (Industrial Applicability) In the present invention, since the plurality of projections are provided on the inner surface side of the steel and the projections are set so as to satisfy the specified numerical condition, the adhesion to the concrete can be increased. As a result, the thickness of the wall can be reduced by using such a steel sheet as a wall material.
