Description
本發明是鋼管補強撐材及其製造方法,尤其是有關設置在建築物等鋼結構物的鋼管補強撐材及其製造方法。The present invention relates to a steel pipe reinforcing struts and a method for producing the same, and more particularly to a steel pipe reinforcing struts provided on steel structures such as buildings and a method for manufacturing the same.
設置在鋼結構物的鋼管補強撐材是將扁鋼所成的軸材插入補強鋼管對角線的位置,壓縮力作用於軸材的長方向時約束面外(長方向的直角方向)的撓曲,可增大能量吸收能力。The steel pipe reinforcing struts provided in the steel structure are inserted into the diagonal line of the reinforcing steel pipe by the flat steel, and the compression force acts on the outer side of the shaft when the compression force acts on the outer side of the shaft (the direction perpendicular to the long direction) Qu, can increase the energy absorption capacity.
此時,軸材與補強鋼管內面即使滑動而為了防止摩擦聲音的發生或為了降低摩擦,將墊板插入兩者的間隙,或是對鋼結構物的確實設置,在軸材的管軸方向的端部設置比補強鋼管對角線長度寬的寬接頭構件(以下稱「端構件」)。At this time, even if the inner surface of the shaft material and the reinforcing steel pipe are slid, in order to prevent the occurrence of friction sound or to reduce the friction, the backing plate is inserted into the gap between the two, or the steel structure is reliably disposed in the tube axis direction of the shaft material. The end portion is provided with a wide joint member (hereinafter referred to as "end member") which is wider than the diagonal length of the reinforcing steel pipe.
此外,揭示有可容易進行墊片的插入,並可提高端構件形狀的自由度的撐材(與鋼管補強撐材相同)的製造方法(例如,參閱專利文獻1)。In addition, a method of manufacturing a struts (the same as the steel pipe reinforcing struts) which can easily insert the shims and improve the degree of freedom of the shape of the end members is disclosed (for example, see Patent Document 1).
[先前技術文獻][Previous Technical Literature]
[專利文獻][Patent Literature]
[專利文獻1]日本特開2001-132112號公報(第3-4頁、第2圖)[Patent Document 1] JP-A-2001-132112 (pages 3-4, 2)
上述專利文獻1所揭示的撐材的製造方法是將一對鋼板彎曲加工成剖面逆ㄈ字型或剖面ㄑ字型(或可為L字型。以下皆同),配置該等包圍著軸材,並將各個側緣彼此焊接接合形成剖面矩形的補強鋼管。The method for producing a susceptor disclosed in Patent Document 1 is to bend a pair of steel sheets into a cross-sectional inverted shape or a cross-sectional shape (or an L-shaped type. The same applies hereinafter), and the surrounding members are arranged to surround the shaft member. And each side edge is welded to each other to form a cross-sectional rectangular reinforcing steel pipe.
因此,可容易進行墊板的配置,並提升間隙的精度,提高補強效果。此外,可選定端構件的形狀而不為補強鋼管的大小所左右但具有以下的問題。Therefore, the configuration of the mat can be easily performed, and the precision of the gap can be improved to enhance the reinforcing effect. Further, the shape of the end member can be selected without being affected by the size of the reinforcing steel pipe but having the following problems.
(a)補強鋼管為長尺寸,為了精度良好地進行長尺寸的扁鋼的彎曲加工,必須具備有相當能力的高壓機。因此,從製造用之設備上的限制,會導致製造者(applicator)的限定。(a) The reinforcing steel pipe is long in size, and it is necessary to have a high-pressure machine having considerable capability in order to accurately bend the long flat steel. Therefore, restrictions on the device from manufacture can lead to limitations of the applicator.
(b)針對扁鋼的彎曲加工所形成的補強鋼管,軸材相對的補強鋼管外側角部的曲率半徑在扁鋼的板厚為6mm以上的場合,必須要板厚的10倍以上,小於板厚的10倍的場合必須取得特別材料的認定(參照日本建築基準法「H12建告2464第1三號八」)。因此,為確實抑制面外壓曲必須取得特別材料的認定。(b) For the reinforced steel pipe formed by the bending of the flat steel, the radius of curvature of the outer corner portion of the reinforcing steel pipe opposite to the shaft material is required to be 10 times or more the thickness of the flat steel when the thickness of the flat steel is 6 mm or more, which is less than the plate. When it is 10 times thicker, it is necessary to obtain the identification of special materials (refer to the Japanese Building Standards Act "H12 Construction 2464 No. 1 No. 8"). Therefore, in order to suppress the out-of-plane buckling, it is necessary to obtain the identification of special materials.
因此,不須進行彎曲加工,並配置可包圍軸材的補強鋼管的製造方法可考慮將4片扁鋼焊接成角形狀加以組裝方法(以下稱「焊接4面箱」)。但是,使用焊接4面箱作為鋼管補強撐材的補強鋼管的場合,會有以下的問題。Therefore, a method of manufacturing a reinforcing steel pipe that can surround the shaft material without bending is considered to be a method of assembling four flat steels into an angular shape (hereinafter referred to as "welding four-sided box"). However, when a welded four-sided box is used as the reinforcing steel pipe for reinforcing the steel pipe, there are the following problems.
(c)在主軸材的側緣附近,由於藉主軸材的面外壓曲對補強鋼管施加由內側向外擴開的力,因此鋼管角部的焊接上,對板厚內面側有未焊接的部份使用熔透焊接時,會降低補強效果,形成鋼管斷裂的起點。(c) In the vicinity of the side edge of the main shaft material, the force applied from the inside to the reinforcing steel pipe is applied by the out-of-plane buckling of the main shaft material. Therefore, the welding of the corner portion of the steel pipe is not welded to the inner side of the plate thickness. When the part is welded, it will reduce the reinforcing effect and form the starting point of the fracture of the steel pipe.
(d)對鋼管角部的焊接使用焊接板厚全厚的完全熔透焊接的場合,有在鋼管內側(鋼管內面側)設置襯環的必要,會與軸材或墊板接觸,不能確保適當的間隙。(d) When welding the corners of the steel pipe using a full thickness weld with a full thickness of the welded plate, it is necessary to provide a lining ring on the inside of the steel pipe (the inner side of the steel pipe), and it will be in contact with the shaft or the backing plate. Proper clearance.

(I)本發明涉及的鋼管補強撐材是將4片的扁鋼側緣對接,藉部份熔透焊接形成外側角部,並藉著填角焊形成與上述主軸材側緣相對的鋼管內側角隅部,形成為剖面矩形,不須進行扁鋼的彎曲加工,並可對主軸材的面外壓曲產生從鋼管內側的推壓力以防止補強鋼管的破裂。(I) The steel pipe reinforcing struts according to the present invention are obtained by butting four side edges of the flat steel, forming a lateral corner portion by partial penetration welding, and forming a steel pipe inner side opposite to the side edge of the main shaft material by fillet welding. The corner portion is formed into a rectangular cross section, and it is not necessary to perform bending processing of the flat steel, and the outer surface buckling of the main shaft material can generate a pressing force from the inner side of the steel pipe to prevent cracking of the reinforcing steel pipe.
再者,除去和主軸材的側緣相對之鋼管內側角隅部的內面角隅部雖未實施填角焊,但是對於後者不會產生有如前者的應力,因此補強鋼管不會斷裂。Further, although the fillet weld is not performed on the inner corner corner portion of the inner corner portion of the steel pipe which is opposed to the side edge of the main shaft member, the stress does not occur in the latter, so that the reinforcing steel pipe does not break.
並且,在與主軸材的側緣相對的鋼管內側角隅面沒有設置襯環的必要,補強鋼管與軸材或墊板之間,可確保適當的間隙。Further, it is not necessary to provide a liner ring on the inner corner surface of the steel pipe facing the side edge of the main shaft material, and an appropriate gap can be secured between the reinforcing steel pipe and the shaft material or the backing plate.
(II)並且,在補強鋼管的內側角隅部和主軸材側緣的間隙配置有墊板,因此可正確約束主軸材的面外變形(撓曲),且即使兩者滑動仍可獲得摩擦聲的發生防止及摩擦的降低。(II) Further, a backing plate is disposed in the gap between the inner corner portion of the reinforcing steel pipe and the side edge of the main shaft material, so that the out-of-plane deformation (deflection) of the main shaft material can be correctly restrained, and the friction sound can be obtained even if both are slid. The occurrence of prevention and the reduction of friction.
(III)另外,在主軸材的側面設置有扁鋼所成的副軸材,因此可約束軸方向對壓縮力的面外變形,增大吸收能量。(III) In addition, since the sub-shaft member made of the flat steel is provided on the side surface of the main shaft member, the out-of-plane deformation of the compressive force in the axial direction can be restricted, and the absorbed energy can be increased.
(IV)又,在主軸材軸方向的端部設置有比補強鋼管對角線的長度寬的扁鋼所成的端構件,因此可確實形成對鋼結構物的連接,使得主軸材的能量吸收更為確實。(IV) Further, an end member formed of a flat steel having a length longer than a diagonal line of the reinforcing steel pipe is provided at an end portion in the direction of the main shaft axis, so that the connection to the steel structure can be surely formed, so that the energy absorption of the main shaft material is achieved. More certain.
(V)此外,本發明所涉及鋼管補強撐材之製造方法,具有:藉填角焊內側角隅部成最終焊接,並藉部份熔透焊接來臨時焊接外側角部形成補強構件的步驟;藉部份熔透焊接來臨時焊接外側角部進行補強鋼管臨時組裝的步驟;及藉部份熔透焊接來最終焊接外側角部進行補強鋼管最終組裝的步驟,因此不須進行扁鋼的彎曲加工,並可抑制因焊接熱導致鋼管的彎曲或翹曲形成補強鋼管。(V) In addition, the method for manufacturing a steel pipe reinforcing struts according to the present invention has the steps of: forming a final welding by filling the inner corner of the fillet, and temporarily welding the outer corner to form a reinforcing member by partial penetration welding; The step of temporarily welding the outer corners by means of partial penetration welding for the temporary assembly of the reinforcing steel pipes; and the step of finally welding the outer corners by partial penetration welding to complete the final assembly of the reinforcing steel pipes, so that the bending of the flat steel is not required And can prevent the bending or warping of the steel pipe due to welding heat to form a reinforcing steel pipe.
(VI)並以排列配置的半自動焊接機同時進行補強鋼管臨時焊接後之外側角部中的2處外側角部來進行補強鋼管的最終組裝,因此可減少焊接時使鋼管補強撐材旋轉的次數,縮短製造步驟。(VI) The semi-automatic welding machine arranged in a row performs the final assembly of the reinforcing steel pipe at the two outer corners of the outer corner after the temporary welding of the reinforcing steel pipe, thereby reducing the number of times the steel pipe is reinforced by the reinforcing struts during welding. , shorten the manufacturing steps.
(VII)另外,在補強構件臨時組裝之前具有配置墊板的步驟,因此可容易進行墊板的配置,並可提高精度,提升補強效果。(VII) In addition, the step of arranging the backing plate is provided before the temporary assembly of the reinforcing member, so that the configuration of the backing plate can be easily performed, and the precision can be improved and the reinforcing effect can be improved.
(VIII)並在上述主軸材的側面設置有扁鋼所成的副軸材,可約束軸方向對壓縮力的面外變形,增大吸收能量。(VIII) A sub-shaft made of flat steel is provided on the side surface of the above-mentioned main shaft material, and the out-of-plane deformation of the compressive force in the axial direction can be restrained, and the absorbed energy can be increased.
(IX)又由於製造時端構件不貫穿補強鋼管的內部,因此端構件的大小或形狀不會為補強鋼管的大小所左右。因此,可設置比補強鋼管對角線的長度寬的扁鋼所成的端構件,可形成對鋼結構物的連接,使主軸材的能量吸收更為確實。(IX) Since the end member does not penetrate the inside of the reinforcing steel pipe at the time of manufacture, the size or shape of the end member is not affected by the size of the reinforcing steel pipe. Therefore, an end member made of a flat steel having a wider length than the diagonal of the reinforcing steel pipe can be provided, and the connection to the steel structure can be formed to make the energy absorption of the main shaft material more reliable.

The cross-sectional view in the front view direction (the XX cross section in Fig. 1(b)), and Fig. 2(b) are the cross-sectional views in the front view in the enlarged view of the part (a) of Fig. 2 . Further, each drawing is shown by a mode, and the relative size, thickness, and the like of each member are not limited by the dimensions shown in the drawings. In addition, in the description of the common part, the description of the added character "a, b" of the symbol is omitted.
第1圖及第2圖中,鋼管補強撐材100,具有:軸材10;包圍軸材10約束主軸材的面外變形用的補強鋼管20;在軸材10長方向的兩端分別固定,可確實對(未圖示)鋼結構物進行設置用的端構件(相當於接頭構件)30a、30b;及配置在軸材10的側緣與補強鋼管20內面的間隙的墊板40a、40b。In the first and second figures, the steel pipe reinforcing struts 100 have a shaft member 10; a reinforcing steel pipe 20 for surrounding the out-of-plane deformation of the main shaft member surrounding the shaft member 10; and fixed at both ends in the longitudinal direction of the shaft member 10, An end member (corresponding to the joint member) 30a and 30b for providing a steel structure (not shown), and a backing plate 40a, 40b disposed at a gap between the side edge of the shaft member 10 and the inner surface of the reinforcing steel pipe 20 .
軸材10,係由:較補強鋼管20短的扁鋼所成的主軸材11,及分別固定在主軸材11兩側面的扁鋼所成的副軸材12、13所形成,呈剖面十字型。此時,一方副軸材12的側緣和另一方副軸材13的側緣的距離(以下,稱「寬度B2」)是形成小於主軸材11兩側緣間的距離(以下,稱「寬度B1」)(B2<B1)。The shaft member 10 is formed of a main shaft member 11 made of flat steel having a shorter reinforcing steel pipe 20, and sub-shaft members 12 and 13 formed of flat steel fixed to both side faces of the main shaft member 11, respectively, in a cross-shaped cross shape. . At this time, the distance between the side edge of one of the sub-shaft members 12 and the side edge of the other sub-shaft member 13 (hereinafter referred to as "width B2") is smaller than the distance between the side edges of the main-shaft member 11 (hereinafter, referred to as "width" B1") (B2 < B1).
再者,本發明不僅限於軸材10的圖示形態,也可以僅未固定有副軸材12、13的主軸材11。Furthermore, the present invention is not limited to the illustrated form of the shaft member 10, and only the main shaft member 11 to which the sub-shaft members 12 and 13 are not fixed may be used.
補強鋼管20是比軸材10長的剖面四角形的筒狀,將4片扁鋼21、22、23、24的側緣彼此互相焊接結合。The reinforcing steel pipe 20 is a tubular shape having a rectangular cross section longer than the shaft member 10, and the side edges of the four flat steels 21, 22, 23, and 24 are welded to each other.
亦即,在扁鋼21側面對接扁鋼22的側端面呈剖面ㄑ字型,內側角隅部(凹面側的對接部)25a是藉填角焊W1,外側角部(凸面側的對接部)25b是藉部份熔透焊接W4(在長方向斷續地部份熔透焊接W24)來焊接結合。That is, the side end surface of the flat steel 22 on the side of the flat steel 21 has a cross-sectional U-shape, and the inner corner portion (the abutting portion on the concave side) 25a is a fillet weld W1, and the outer corner portion (the abutment portion on the convex side) 25b is welded by a partial penetration weld W4 (partially through the weld W24 in the longitudinal direction).
又,扁鋼23和扁鋼24對接的內側角隅部26a及外側角部26b也同樣實施填角焊W1及部份熔透焊接W4(在長方向斷續地部份熔透焊接W24)。Further, the inner corner portion 26a and the outer corner portion 26b in which the flat steel 23 and the flat steel 24 are butted are also subjected to fillet welding W1 and partial penetration welding W4 (partially penetrated and welded W24 in the longitudinal direction).
此外,扁鋼24的側端面對接於扁鋼21側面呈剖面ㄑ字型,角部(凸面側的對接部)28b是以部份熔透焊接W5(在長方向斷續地部份熔透焊接W35)來焊接結合。此時,角隅部(凹面側的對接部)未施以填角焊。並且,由於扁鋼23和扁鋼22的結合也是同樣,因此省略說明。In addition, the side end surface of the flat steel 24 is butt-joined on the side of the flat steel 21, and the corner portion (the abutting portion on the convex side) 28b is a partial penetration weld W5 (partially melted in the long direction) Through welding W35) to weld the bond. At this time, the corner portion (the abutting portion on the concave side) is not subjected to fillet welding. Further, since the combination of the flat steel 23 and the flat steel 22 is also the same, the description is omitted.
並且,補強鋼管20是藉以上焊接形態所形成,因此彎曲或翹曲少,且無矯正的必要。(對此,在實施形態2中詳細說明。)Further, since the reinforcing steel pipe 20 is formed by the above welding form, it is less curved or warped, and there is no need for correction. (This will be described in detail in the second embodiment.)
端構件30a、30b(以下,匯集或一方稱為「端構件30」),具有:固定於主軸材11的長方向端部的主端構件31,及固定在副軸材12、13的長方向端部的副端構件32、33。主端構件31的兩側面固定著副端構件32、33,呈剖面十字型。The end members 30a and 30b (hereinafter referred to as "end members 30") have a main end member 31 fixed to the longitudinal end portion of the main shaft member 11 and fixed to the longitudinal direction of the sub-shaft members 12 and 13. The secondary end members 32, 33 of the ends. The secondary end members 32, 33 are fixed to both side faces of the main end member 31 in a cross-shaped cross shape.
此時,主端構件31及副端構件32在接近軸方向的補強鋼管20的範圍,寬度變窄,進入到補強鋼管20的內部。另一方面,從補強鋼管20突出的軸方向的端部附近,主端構件31兩側緣間的距離(以下,稱「寬度B3」)及副端構件32的側緣和另一方的副端構件33的側緣的距離(以下,稱「寬度B4」)皆充分大於補強鋼管20之內面對角線的長度。At this time, the main end member 31 and the sub-end member 32 are narrowed in the range of the reinforcing steel pipe 20 in the axial direction, and enter the inside of the reinforcing steel pipe 20. On the other hand, in the vicinity of the end portion in the axial direction from which the reinforcing steel pipe 20 protrudes, the distance between the side edges of the main end member 31 (hereinafter referred to as "width B3") and the side edge of the sub-end member 32 and the other sub-end end The distance of the side edge of the member 33 (hereinafter, referred to as "width B4") is sufficiently larger than the length of the diagonal line inside the reinforcing steel pipe 20.
此外,以上的說明中,雖在主端構件31及副端構件32、33形成有設置於鋼結構物用之螺栓貫穿的貫穿孔34等,但是本發明不僅限於圖式的形態。例如,也可以不設置貫穿孔34等,而是將主端構件31及副端構件32、33的端部焊接結合在鋼結構物。此時,在鋼結構物設置有形成和主端構件31及副端構件32、33所形成端部形狀相同的端部形狀的角撐板。In the above description, the main end member 31 and the sub-end members 32 and 33 are formed with the through holes 34 and the like which are provided in the bolts for the steel structure, but the present invention is not limited to the form of the drawings. For example, the end portions of the main end member 31 and the sub-end members 32 and 33 may be welded to the steel structure without providing the through holes 34 or the like. At this time, the steel structure is provided with a gusset having an end shape having the same shape as that of the end portions of the main end member 31 and the sub-end members 32, 33.
(墊板)(pad)
墊板40是配置在主軸材11的側緣部與補強鋼管20內面的間隙,當主軸材11成面外變形(撓曲)時,適當設定約束面外變形的變形量,可提升補強效果。又,主軸材11的側緣部和補強鋼管20的內面是透過墊板40對接,不會直接滑動,可獲得摩擦聲的發生防止及摩擦的降低。The backing plate 40 is disposed in a gap between the side edge portion of the main shaft member 11 and the inner surface of the reinforcing steel pipe 20. When the main shaft member 11 is deformed (deflected) out of plane, the amount of deformation of the outer surface of the restraining surface is appropriately set, and the reinforcing effect can be improved. . Further, the side edge portion of the main shaft member 11 and the inner surface of the reinforcing steel pipe 20 are butted against each other through the backing plate 40, and the direct friction is prevented from being directly slid, and the occurrence of frictional noise and the reduction in friction can be obtained.
再者,形成墊板的材質並不限定為特定的材質,也可以是硬質的合成樹脂及天然橡膠或人工橡膠等。Further, the material for forming the backing plate is not limited to a specific material, and may be a hard synthetic resin, natural rubber or artificial rubber.

第6圖是說明本發明實施形態3所涉及鋼管補強撐材的製造方法的圖,模式表示第6步驟(S6)的前視方向的剖面圖。並與實施形態2相同部份或相當的部份賦予相同符號,省略一部份的說明。Fig. 6 is a view for explaining a method of manufacturing a steel pipe reinforcing struts according to a third embodiment of the present invention, and a schematic cross-sectional view showing a sixth step (S6) in a front view. The same or equivalent portions as those in the second embodiment are denoted by the same reference numerals, and a part of the description will be omitted.
實施形態3中,藉著具備2連續的焊槍的焊接機(半自動焊接機)執行實施形態2的第6步驟(S6)。焊接機70,具有:作業架71;作業站72;可自由移動地設置在作業架72的作業臂73;設置在作業臂73的焊槍60a、60b;對焊槍60a、60b供應預定電流的電源手段(含控制手段。未圖示);及對焊槍60a、60b供應焊接資材(焊絲、惰性氣體等)的資材供應手段(未圖示)。In the third embodiment, the sixth step (S6) of the second embodiment is executed by a welding machine (semi-automatic welding machine) having two continuous welding torches. The welding machine 70 has a work frame 71, a work station 72, a work arm 73 movably provided on the work frame 72, welding torches 60a and 60b provided on the work arm 73, and a power supply means for supplying a predetermined current to the welding torches 60a and 60b. (including control means. Not shown); and means for supplying materials (not shown) for supplying welding materials (welding wire, inert gas, etc.) to the welding torches 60a, 60b.
第6圖的(a)中,旋轉補強鋼管20使兩側形成有型斜切的扁鋼24(參閱第5圖的(d))呈水平且位於上側,載放於作業台71。In (a) of Fig. 6, the rotary reinforcing steel pipe 20 is formed on both sides. The beveled flat steel 24 (see (d) of Fig. 5) is horizontal and located on the upper side, and is placed on the work table 71.
並且,設置使焊槍前端61a、61b來到形成於扁鋼24兩側的型斜切(外側角部)26b、28b的正上方。And, the welding gun front ends 61a, 61b are arranged to be formed on both sides of the flat steel 24 The type of beveled (outer corners) 26b, 28b directly above.
因此,並移動作業臂73(焊槍前端61a、61b與補強鋼管20的軸方向平行一起移動),同時進行外側角部26b、28b的部份熔透焊接。Therefore, the working arm 73 is moved (the welding gun front ends 61a and 61b move in parallel with the axial direction of the reinforcing steel pipe 20), and at the same time, partial penetration welding of the outer corner portions 26b and 28b is performed.
接著,設置使補強鋼管20逆轉180度使扁鋼22呈水平且來到上面,以下以同樣的順序,同時進行外側角部25b、27b的部份熔透焊接。Next, the reinforcing steel pipe 20 is reversely rotated by 180 degrees so that the flat steel 22 is horizontal and comes to the upper side, and the partial penetration welding of the outer corner portions 25b and 27b is simultaneously performed in the same order.
如上述,臨時焊接後的外側角部中,由於同時最終焊接2處的外側角部進行補強鋼管20的最終焊接,因此可抑制因焊接熱影響導致鋼管的彎曲或翹曲。As described above, in the outer corner portion after the temporary welding, since the outer corner portion of the second welding is simultaneously welded to the final welding of the reinforcing steel pipe 20, it is possible to suppress the bending or warpage of the steel pipe due to the influence of the welding heat.
再者,扁鋼24和扁鋼22的焊接順序何者為先皆可。Furthermore, the welding sequence of the flat steel 24 and the flat steel 22 is the first one.
並且,本發明不僅限於焊接機70的型式,也可以移動作業台71來取代作業臂73。或也可將焊槍60a、60b分別設置在各個的作業臂上。Further, the present invention is not limited to the type of the welding machine 70, and the work table 71 may be moved instead of the working arm 73. Alternatively, the welding guns 60a, 60b may be provided on the respective working arms.

並且,轉動補強鋼管20使外側角部27b及外側角部28b彼此成水平且位於上側,載放在作業台71上。Further, the rotating reinforcing steel pipe 20 has the outer corner portion 27b and the outer corner portion 28b horizontally positioned on the upper side and placed on the work table 71.
因此,設置使焊槍前端61a、61b來到外側角部27b、28b的正上方,移動作業臂73(焊槍前端61a、61b與補強鋼管20的軸方向平行一起移動),同時進行外側角部27b、28b的部份熔透焊接。Therefore, the welding gun front ends 61a and 61b are provided directly above the outer corner portions 27b and 28b, and the working arm 73 is moved (the welding gun front ends 61a and 61b move in parallel with the axial direction of the reinforcing steel pipe 20), and the outer corner portion 27b is simultaneously Partial penetration penetration of 28b.
接著,將補強鋼管20成180度逆轉,設置使外側角部25b、26b彼此成水平且來到上面,以後以同樣的順序,同時進行外側角部25b、26b的部份熔透焊接。Next, the reinforcing steel pipe 20 is reversed at 180 degrees, and the outer corner portions 25b, 26b are placed horizontally and come to the upper surface, and then the partial penetration welding of the outer corner portions 25b, 26b is simultaneously performed in the same order.

(實施例)(Example)
其次,針對比較實施形態1所涉及鋼管補強撐材(與藉著實施形態2涉及的鋼管補強撐材的製造方法所製造的鋼管補強撐材相同,以下有稱「焊接4面箱型」的場合)的實施例,及將一對鋼板彎曲加工成剖面ㄑ字型,配置該等包圍著軸材,並將各個端緣彼此焊接形成剖面矩形的補強鋼管的補強鋼管撐材(以下有稱「ㄑ字型加壓式」)的比較例之性能的實驗說明如下。Next, the steel pipe reinforcing struts according to the first embodiment are the same as those of the steel pipe reinforcing struts manufactured by the method for producing a steel pipe reinforcing struts according to the second embodiment, and the following is the case of "welding four-sided box type". In the embodiment, a pair of steel plates are bent into a cross-sectional U-shape, and the reinforcing steel pipe struts are formed by surrounding the shaft members and welding the respective end edges to each other to form a cross-sectional rectangular reinforcing steel pipe (hereinafter referred to as "ㄑ" The experiment of the performance of the comparative example of the font type "pressure type") is explained below.
第7圖是說明使用於實驗的試片的圖,(a)為實施例的上視圖,(b)為實施例的側視圖、(c)為實施例的前視方向的剖面圖(第7圖的(a)的A-A剖面)、(d)為比較例前視方向的剖面圖。Figure 7 is a view for explaining a test piece used in an experiment, (a) is a top view of the embodiment, (b) is a side view of the embodiment, and (c) is a cross-sectional view of the front view of the embodiment (No. 7) AA cross section (a) and (d) of the figure (a) are cross-sectional views of the comparative example in the front view direction.
第7圖的(a)~(c)中,實施例相對於鋼管板厚9mm,內側填角焊為腳長3mm、外側部份熔透焊接為斜切角度45度、斜切深度為7mm。In (a) to (c) of Fig. 7, the embodiment has a thickness of 9 mm with respect to the steel pipe, the inner fillet weld has a length of 3 mm, and the outer portion has a bevel angle of 45 degrees and a bevel depth of 7 mm.
第7圖的(d)中,比較例針對軸材剖面形狀、鋼管徑及板厚都是與實施例相同,但是補強鋼管的製造方法不同。In (d) of Fig. 7, the comparative example has the same cross-sectional shape, steel pipe diameter, and thickness as the embodiment, but the manufacturing method of the reinforcing steel pipe is different.
表1是顯示實施例及比較例的各條件與進行等幅承載試驗的結果。Table 1 shows the results of the respective examples and comparative examples and the results of carrying out the equal-width load test.
表1中的「重複次數」是表示作為鋼管補強撐材之疲勞特性的指標,顯示軸材的最大耐力以後,到耐力降低至最大耐力的70%為止的重複次數。又,表1中的「累積塑性變形倍率」是表示作為鋼管補強撐材之能量吸收能力的指標,以到達上述重複次數為止的滯後曲線(耐力-變形曲線)的內側面積除以「屈服耐力×屈服變形」的長方形面積後的值。The "number of repetitions" in Table 1 is an index indicating the fatigue characteristics of the steel pipe reinforcing struts, and shows the number of repetitions until the endurance is reduced to 70% of the maximum endurance after the maximum endurance of the shaft material. In addition, the "accumulated plastic deformation ratio" in Table 1 is an index indicating the energy absorption capacity of the steel pipe reinforcing struts, and the inner area of the hysteresis curve (endurance-deformation curve) up to the above-mentioned number of repetitions is divided by "yield endurance × The value after the rectangular area of the yield deformation.
表1中,對於重複次數,實施例(焊接4面箱型)的一方若干多於比較例(ㄑ字型加壓式)。In Table 1, for the number of repetitions, one of the examples (welding four-sided box type) was more than the comparative example (ㄑ-type pressurized type).
並且,對於累積塑性變形倍率雖然實施例的一方形成若干低於比較例的值,但是兩者和相當於大地震兩次量的必要累積塑性變形倍率的「300」比較時是形成充分大的值。並且,兩者的差可謂在誤差的範圍內,因此實施例可謂和比較例相同,具備充分的性能。In addition, in the case of the cumulative plastic deformation magnification, the number of the examples is lower than the value of the comparative example. However, when the two are compared with "300" which is the necessary cumulative plastic deformation magnification corresponding to the large earthquake, the value is sufficiently large. . Further, the difference between the two can be said to be within the range of the error. Therefore, the embodiment can be said to have sufficient performance as in the comparative example.
再者,實施例在耐力低於最大耐力的70%之後,也未見有急遽的耐力降低,最後不會產生鋼管焊接部的斷裂。Further, in the example, after the endurance was less than 70% of the maximum endurance, no impaired endurance was observed, and finally, the fracture of the welded portion of the steel pipe did not occur.

第9圖的(b)及(c)表示的第5步驟中,臨時組裝有補強鋼管20。此時,定位材50a、50b可容易進行補強構件25和補強構件26的對位,並且可提高兩者的對接精度,而可臨時組裝形狀精度高的補強鋼管20。In the fifth step shown in (b) and (c) of Fig. 9, the reinforcing steel pipe 20 is temporarily assembled. At this time, the positioning members 50a and 50b can easily perform the alignment of the reinforcing member 25 and the reinforcing member 26, and the docking accuracy of both can be improved, and the reinforcing steel pipe 20 having high shape accuracy can be temporarily assembled.
並且,定位材50a、50b並非補強鋼管20的強度構件,因此設置可供定位的程度(例如,點焊等)。再者,定位材50a、50b的數量不加以限定,並且,也可以分別設置於扁鋼22及扁鋼24來取代扁鋼21及扁鋼23。此外,也可在形成補強構件25、26之後(執行填角焊W1或部份熔透焊接W2之後)設置定位材50a、50b,也可使用預先設有定位材50a、50b的扁鋼21、23形成補強構件25、26。Further, the positioning members 50a, 50b are not the strength members of the reinforcing steel pipe 20, and therefore are provided for the degree of positioning (for example, spot welding or the like). Further, the number of the positioning members 50a and 50b is not limited, and may be provided in the flat steel 22 and the flat steel 24 instead of the flat steel 21 and the flat steel 23, respectively. Further, the positioning members 50a, 50b may be provided after the reinforcing members 25, 26 are formed (after the fillet welding W1 or the partial penetration welding W2 is performed), and the flat steel 21 provided with the positioning members 50a, 50b in advance may be used. 23 forms reinforcing members 25, 26.
