Description
本發明是有關於一種補強構件，特別是有關於一種包括對地震產生時的地震能量進行吸收的軸向力構件、以及對所述軸向力構件進行加強的加強管的補強構件。 The present invention relates to a reinforcing member, and particularly to a reinforcing member including an axial force member that absorbs seismic energy when an earthquake occurs and a reinforcing tube that reinforces the axial force member.
先前，設置於建築構造物上、用以應對地震產生的補強構件包括對地震能量進行吸收的軸向力構件、以及當壓縮力在軸向力構件的長度方向上起作用時對面外(與長度方向垂直的方向)的撓曲進行限制的加強材料，在壓縮軸向力起作用時亦防止軸向力構件的整體挫屈(buckle)的產生或使產生時間延遲，從而產生穩定的軸向變形，增大地震能量的吸收能力。 Previously, the reinforcement members installed on building structures to deal with earthquakes include axial force members that absorb seismic energy, and when the compression force acts in the longitudinal direction of the axial force members, they (The direction perpendicular to the direction) the reinforcing material that limits the deflection, and prevents the occurrence of the overall buckle of the axial force member when the compression axial force acts, or delays the generation time, thereby generating stable axial deformation , Increase the absorption capacity of seismic energy.
並且，專利申請人已揭示一種補強構件，可排除用以將軸向力構件及加強材料配置成規定形態的焊接作業或在軸向力構件與加強材料之間填塞砂漿(mortar)的作業，而容易地進行製造，並且可防止重量的增加(例如，參照專利文獻1)。 Moreover, the patent applicant has disclosed a reinforcing member, which can exclude welding operations for arranging the axial force member and the reinforcing material into a prescribed form or the operation of filling the mortar between the axial force member and the reinforcing material, and It is easy to manufacture, and an increase in weight can be prevented (for example, refer to Patent Document 1).
[專利文獻1]日本專利特開2013-112949號公報(第4-5頁，圖1) [Patent Document 1] Japanese Patent Laid-Open No. 2013-112949 (page 4-5, Fig. 1)
所述專利文獻1所揭示的補強構件是在貫穿加強管的由條鋼構成的軸向力構件的兩端分別螺紋連接著U形夾(clevis)。而且，經由與加強管及軸向力構件分別螺合的止動環，加強管的一個端部螺紋固定於軸向力構件的一個端部。另一方面，在軸向力構件的另一個端部，螺紋固定有由鋼管構成的套筒(sleeve)，套筒的長度方向上的大致一半侵入至加強管內，剩餘的大致一半自加強管露出。此時，在套筒的外周與加強管的內周之間，形成有規定大小的間隙。因此，所述補強構件獲得如下顯著的效果：可不進行焊接作業而使軸向力構件相對於加強管配置於規定的位置，並且可排除在軸向力構件與加強材料之間填塞砂漿的作業。 The reinforcing member disclosed in the above-mentioned Patent Document 1 is that a U-shaped clamp (clevis) is screwed to both ends of an axial force member made of bar steel that penetrates a reinforcing tube. Furthermore, one end of the reinforcement tube is screwed to one end of the axial force member via stop rings that are screwed to the reinforcement tube and the axial force member, respectively. On the other hand, at the other end of the axial force member, a sleeve made of a steel pipe is screwed, and approximately half of the length of the sleeve intrudes into the reinforcing tube, and the remaining approximately half is from the reinforcing tube Exposed. At this time, a gap of a predetermined size is formed between the outer periphery of the sleeve and the inner periphery of the reinforcing tube. Therefore, the reinforcing member has a remarkable effect that the axial force member can be arranged at a predetermined position with respect to the reinforcing tube without welding operation, and the operation of stuffing the mortar between the axial force member and the reinforcing material can be eliminated.
但是，套筒的壁厚需要小於加強材料的內徑與軸向力構件的外徑之差的一半，另一方面，加強材料的內表面較佳為位於與軸向力構件的外表面相近的位置，以便發揮加強性能。 However, the wall thickness of the sleeve needs to be less than half of the difference between the inner diameter of the reinforcing material and the outer diameter of the axial force member. On the other hand, the inner surface of the reinforcing material is preferably located close to the outer surface of the axial force member Position in order to play enhanced performance.
因此，套筒的壁厚自身具有限度，藉由所述限度，當套筒的彎曲耐力小時，有可能在套筒的自加強管露出的範圍內因彎曲而產生屈服。如此一來，在加強管的另一個端面與螺紋固定於軸向力構件的另一個端部的U形夾的端部之間，由於原本沒有加強管，且套筒亦已屈服，故而在其間，軸向力構件有可能產生挫屈。 Therefore, the wall thickness of the sleeve itself has a limit by which, when the bending endurance of the sleeve is small, it is possible to yield due to bending in the range where the self-reinforcing tube of the sleeve is exposed. In this way, between the other end face of the reinforcing tube and the end of the U-shaped clamp screwed to the other end of the axial force member, since there is no reinforcing tube originally, and the sleeve has also yielded, there is , Axial force members may produce buckling.
因此，需要一種藉由替代套筒的機構來提高(大的)彎曲耐力的補強構件。 Therefore, there is a need for a reinforcing member that improves (large) bending endurance by a mechanism that replaces the sleeve.
本發明是因應所述需要而成，目的在於提供一種彎曲耐 力高的(大的)補強構件。 The present invention is made in response to the above-mentioned needs, and aims to provide a bending resistance High (large) reinforcement members.
(1)本發明的補強構件的特徵在於包括：軸向力構件；加強管，所述軸向力構件所貫穿，用以對所述軸向力構件的面外變形進行限制；卡口，設置有所述軸向力構件的長度方向上的一個端部及所述加強管的長度方向上的一個端部；卡口U形夾(clevis)，以朝向與所述軸向力構件及所述加強管相反的方向突出的方式而設置於所述卡口，成為用以設置於建築構造物上的接口；強化材料，設置有所述軸向力構件的長度方向上的另一個端部；以及強化材料U形夾，以朝向與所述軸向力構件相反的方向突出的方式而設置於所述強化材料，成為用以設置於建築構造物上的接口；且所述強化材料包圍自所述加強管的長度方向上的另一個端面算起的規定的範圍。 (1) The reinforcing member of the present invention is characterized by comprising: an axial force member; a reinforcing tube penetrated by the axial force member to limit out-of-plane deformation of the axial force member; a bayonet, provided There is one end in the longitudinal direction of the axial force member and one end in the longitudinal direction of the reinforcing tube; a bayonet clevis (clevis) to face the axial force member and the The reinforcing tube is provided on the bayonet in such a manner that it protrudes in the opposite direction, and becomes an interface for being provided on the building structure; the reinforcing material is provided with the other end portion of the axial force member in the longitudinal direction; and A reinforced material U-shaped clip is provided on the reinforced material so as to protrude in a direction opposite to the axial force member, and becomes an interface for being provided on a building structure; and the reinforced material surrounds from the The specified range from the other end face of the reinforcing tube in the longitudinal direction.
(2)又，其特徵在於包括：軸向力構件；加強管，所述軸向力構件所貫穿，用以對所述軸向力構件的面外變形進行限制； 強化材料，分別設置於所述軸向力構件的長度方向上的兩端；以及強化材料U形夾，以朝向與所述軸向力構件相反的方向突出的方式而分別設置於各個所述強化材料上，成為用以設置於建築構造物上的接口；且所述強化材料分別包圍自所述加強管的長度方向上的端部算起的規定的範圍。 (2) Furthermore, it is characterized by comprising: an axial force member; a reinforcing tube through which the axial force member penetrates to limit out-of-plane deformation of the axial force member; Reinforcement materials are respectively provided at both ends of the axial force member in the longitudinal direction; and U-shaped clips of reinforcement materials are respectively provided at each of the reinforcements so as to protrude in a direction opposite to the axial force member In terms of material, it becomes an interface for installation on a building structure; and the reinforcing materials each surround a predetermined range from the end in the longitudinal direction of the reinforcing tube.
(3)此外，如所述(1)或所述(2)，其特徵在於：所述強化材料的包圍所述加強管的範圍的內徑在長度方向上為固定，所述範圍的外徑越接近於所述加強管的長度方向上的中央越變小。 (3) In addition, as described in (1) or (2), the inner diameter of the range of the reinforcing material surrounding the reinforcing tube is fixed in the longitudinal direction, and the outer diameter of the range The closer to the center in the longitudinal direction of the reinforcing tube, the smaller.
(i)本發明的補強構件是將加強管的長度方向上的一個端部設置於卡口，自加強管的長度方向上的另一個端面算起的規定的範圍由強化材料所包圍。即，強化材料是包圍加強管的外周的構件，而並未對其厚度進行限制，因此與現有的套筒(配置於軸向力構件與加強管的間隙)相比，可增大外徑(內徑亦同)及壁厚，故而可提高剛性。 (i) The reinforcing member of the present invention is provided with one end portion of the reinforcing tube in the longitudinal direction at the bayonet, and a predetermined range from the other end surface of the reinforcing tube in the longitudinal direction is surrounded by the reinforcing material. That is, the reinforcing material is a member that surrounds the outer periphery of the reinforcing tube, and its thickness is not limited. Therefore, compared with the existing sleeve (disposed in the gap between the axial force member and the reinforcing tube), the outer diameter can be increased ( The inner diameter is the same) and the wall thickness, so the rigidity can be improved.
此時，自加強管的長度方向上的另一個端面算起的規定的範圍是藉由剛性高的強化材料來限制變形，因此軸向力構件的挫屈的產生得以抑制，故而可成為彎曲耐力高的(大的)補強構件。 At this time, the predetermined range from the other end surface of the reinforcing tube in the longitudinal direction is limited by the reinforcement material with high rigidity, so the occurrence of the buckling of the axial force member is suppressed, so it can become the bending endurance High (large) reinforcement members.
(ii)又，當自加強管的長度方向上的兩個端部算起的規定的範圍分別由強化材料所包圍時，可獲得所述效果，並且由於不 需要卡口，故可減少零件的種類，從而可對製造成本或庫存成本進行抑制。 (ii) In addition, when the prescribed ranges from the two ends in the longitudinal direction of the reinforcing tube are surrounded by the reinforcing material, the effect can be obtained, and since the A bayonet is required, so the types of parts can be reduced, and the manufacturing cost or inventory cost can be suppressed.
(iii)此外，強化材料的外徑越朝向前端(越接近於加強管的長度方向上的中央)越變小，因此可確保長度方向上的各位置的強度，而且促進重量的減輕以及使設計性提高。 (iii) In addition, the outer diameter of the reinforcing material becomes smaller toward the front end (closer to the center in the longitudinal direction of the reinforcing tube), so the strength at each position in the longitudinal direction can be ensured, and weight reduction and design can be promoted Sexual improvement.

At this time, the central axis of the mounting hole 44 intersects the central axis of the disc-shaped portion 41 perpendicularly (it does not mean that it crosses geometrically and accurately, but industrially).
再者，以上是將卡口30與卡口U形夾40分別個別地加以製造，且藉由螺紋連接而將兩者加以一體化，但本發明並不限定於此，亦可藉由燒嵌等機械接合或焊接等冶金接合來將兩者加以一體化，或者，亦可藉由澆鑄等而將兩者自一開始即製造成一體。 Furthermore, the above is to separately manufacture the bayonet 30 and the bayonet U-shaped clip 40 separately, and integrate the two by screw connection, but the present invention is not limited to this, and can also be embedded by burning They can be integrated by mechanical bonding or metallurgical bonding such as welding, or they can be made into one from the beginning by casting or the like.
(強化材料) (Reinforced material)

A female thread 56 is formed on the other end surface 50 b of the disc-shaped portion 55, and a female thread 51 is formed in a form penetrating through the center.
而且，軸向力構件10的公螺紋12b螺合於母螺紋51，強化材料U形夾60的公螺紋65(關於該點將在後文描述)螺合於母螺紋56。 Further, the male thread 12 b of the axial force member 10 is screwed to the female thread 51, and the male thread 65 of the reinforcing material clevis 60 (which will be described later on this point) is screwed to the female thread 56.
此外，筒狀部52的內徑在長度方向上為固定，筒狀部52的中心軸、母螺紋51的中心軸及母螺紋56的中心軸相一致，筒狀部52包圍著加強管20的長度方向上的另一個端部21b(自端面20b算起的規定距離的範圍)(自加強管20的長度方向上的另一個端面20b算起規定距離的範圍侵入至筒狀部52)。 In addition, the inner diameter of the cylindrical portion 52 is fixed in the longitudinal direction. The central axis of the cylindrical portion 52, the central axis of the female screw 51, and the central axis of the female screw 56 coincide with each other. The cylindrical portion 52 surrounds the reinforcing tube 20.

又，在筒狀部52的外表面上，形成有越接近於長度方向的一個端面(與前端相同)50a外徑越變小的錐形部50c。因此，賦予了使加強管20的光滑性得到強化的印象，故而設計性得到提高。 In addition, on the outer surface of the cylindrical portion 52, a tapered portion 50c having a smaller outer diameter is formed closer to one end surface (the same as the front end) 50a in the longitudinal direction. Therefore, the impression that the smoothness of the reinforcing tube 20 is strengthened is given, so that the designability is improved.

強化材料U形夾60與卡口U形夾40相同，作為用以設置於建築構造物(未圖示)上的接口而發揮作用，包括圓盤狀部分61、設置於圓盤狀部分61的另一個端面的板狀部分62、貫穿板狀部分62的安裝用孔66、以及形成於圓盤狀部分61的外周的公螺紋65。此時，安裝用孔66的中心線與公螺紋65的中心線垂直地交叉(並非指在幾何學上準確地交叉，而是以工業上的精度進行交叉)。 The reinforcing material clevis 60 is the same as the bayonet clevis 40 and functions as an interface for installation on a building structure (not shown), including a disc-shaped portion 61 and a disc-shaped portion 61 The plate-like portion 62 on the other end face, the mounting hole 66 penetrating the plate-like portion 62, and the male screw 65 formed on the outer periphery of the disc-like portion 61. At this time, the center line of the mounting hole 66 crosses the center line of the male screw 65 perpendicularly (it does not mean that it crosses geometrically accurately, but crosses with industrial precision).
再者，強化材料U形夾60具有與卡口U形夾40相同的形狀。 Furthermore, the reinforcing material clevis 60 has the same shape as the bayonet clevis 40.
再者，以上是對強化材料50與強化材料U形夾60分別個別地加以製造，且藉由螺紋連接而將兩者加以一體化，但本發明並不限定於此，亦可藉由燒嵌等機械接合或焊接等冶金接合來將兩者加以一體化，或者，亦可藉由澆鑄等而將兩者自一開始即製造成一體。 Furthermore, the above is the manufacturing of the reinforcing material 50 and the reinforcing material U-shaped clip 60 separately, and the two are integrated by screw connection, but the present invention is not limited to this, and can also be embedded by burning They can be integrated by mechanical bonding or metallurgical bonding such as welding, or they can be made into one from the beginning by casting or the like.
(作用效果) (Effect)
補強構件100是將加強管20的長度方向上的一個端部21a設置於卡口30，且自加強管20的長度方向上的另一個端部20b算起的規定的範圍由強化材料50的筒狀部52所包圍。即，筒狀部52是包圍加強管20的外周的構件，而並未對其厚度進行限制，故而與現有的套筒(配置於軸向力構件與加強管的間隙)相比，可增大外徑(內徑亦同)及壁厚，因此可提高剛性。再者，為了防止因強化材料U形夾60過分地旋轉變形而發生偏心(eccentricity)，而導致彎曲力矩大幅度作用至加強管20，理想的是由筒狀部52包圍的長度lk就和加強管20(與「挫屈限制材料」相同)的外徑與強化材料50的內徑的差ek的關係而言，為ek/lk≦0.05。 The reinforcing member 100 is a cylinder in which one end portion 21a of the reinforcing tube 20 in the longitudinal direction is provided in the bayonet 30, and a predetermined range from the other end portion 20b of the reinforcing tube 20 in the longitudinal direction is a tube of the reinforcing material 50 The shape 52 is surrounded. That is, the cylindrical portion 52 is a member that surrounds the outer periphery of the reinforcing tube 20, and its thickness is not limited, so it can be increased compared to the conventional sleeve (arranged between the axial force member and the reinforcing tube) The outer diameter (the same as the inner diameter) and the wall thickness can increase the rigidity. Furthermore, in order to prevent eccentricity due to excessive rotation deformation of the reinforcing material clevis 60, which causes a large bending moment to act on the reinforcing tube 20, it is desirable that the length l k surrounded by the cylindrical portion 52 be The relationship between the difference e k of the outer diameter of the reinforcing tube 20 (the same as the “buckling restricting material”) and the inner diameter of the reinforcing material 50 is e k / l k ≦ 0.05.
如此一來，自加強管20的長度方向上的另一個端面20b算起的規定的範圍藉由剛性高的強化材料50的筒狀部52來限制變形，因此可抑制軸向力構件10的挫屈的產生(關於該點將另外詳細說明)。 In this way, the predetermined range from the other end surface 20b in the longitudinal direction of the reinforcing tube 20 is restricted by the cylindrical portion 52 of the high-rigidity reinforcing material 50, so that the axial force member 10 can be prevented from falling The generation of flexion (more on this point will be explained in detail).
又，強化材料50的外徑越朝向長度方向上的一個端面50a(前端)(越接近於加強管20的長度方向上的中央)越變小，因此可確保長度方向上的各位置的強度，而且促進重量的減輕以及使設計性提高。 Furthermore, the outer diameter of the reinforcing material 50 decreases toward the one end surface 50a (front end) in the longitudinal direction (closer to the center in the longitudinal direction of the reinforcing tube 20), so the strength at each position in the longitudinal direction can be ensured. It also promotes weight reduction and design improvement.
又，軸向力構件10的兩端分別螺紋連接於卡口30及強化材料50，因此藉由將各個螺紋設為相反方向(例如，將公螺紋12a及母螺紋31設為右螺紋，將公螺紋12b及母螺紋51設為左螺紋)， 可調整安裝用孔44與安裝用孔66的距離，因此補強構件100的設置變得容易。 In addition, since both ends of the axial force member 10 are screwed to the bayonet 30 and the reinforcing material 50, respectively, by setting the respective threads in opposite directions (for example, by setting the male thread 12a and the female thread 31 to the right thread, the male thread Thread 12b and female thread 51 are left threads), Since the distance between the mounting hole 44 and the mounting hole 66 can be adjusted, installation of the reinforcing member 100 becomes easy.

圖4(a)及圖4(b)是表示用以對本發明的實施形態1的補強構件的性能進行確認的負載試驗的結果的荷重-應變線圖，圖4(a)是試驗體1號，圖4(b)是試驗體2號。負載試驗是交替地反覆賦予軸向力構件10的壓縮及拉伸的雙擺動負載。 4 (a) and 4 (b) are load-strain diagrams showing the results of a load test for confirming the performance of the reinforcing member according to Embodiment 1 of the present invention, and FIG. 4 (a) is test body No. 1 Figure 4 (b) is the test body No. 2. The load test is a double-oscillating load that alternately compresses and stretches the axial force member 10.
在圖4(a)中，首先，將軸向力構件10壓縮僅0.25%(將卡口U形夾40的安裝用孔44的中心與強化材料U形夾60的安裝用孔66的中心的「距離l」縮短僅6.25mm)。此時，壓縮荷重及壓縮應變示於第1象限。其次，將軸向力構件10拉伸僅0.25%(將距離l拉伸僅6.25mm)。此時，拉伸荷重及拉伸應變示於第3象限。 In FIG. 4 (a), first, the axial force member 10 is compressed by only 0.25% (the center of the mounting hole 44 of the bayonet clevis 40 and the center of the mounting hole 66 of the reinforcing clevis 60 "The distance l" is shortened by only 6.25mm). At this time, the compressive load and compressive strain are shown in the first quadrant. Secondly, the axial force member 10 is stretched by only 0.25% (the distance l is stretched by only 6.25 mm). At this time, the tensile load and tensile strain are shown in the third quadrant.
進而，將軸向力構件10壓縮僅0.5%(將距離l縮短僅12.5mm)，其次，將軸向力構件10拉伸僅0.5%(將距離l拉伸僅12.5mm)。 Furthermore, the axial force member 10 is compressed by only 0.5% (the distance l is shortened by only 12.5 mm), and secondly, the axial force member 10 is stretched by only 0.5% (the distance l is stretched by only 12.5 mm).
然後，將使軸向力構件10壓縮僅1.0%(將距離l縮短僅25mm)，其次，使軸向力構件10拉伸僅1.0%(將距離l拉伸僅25mm)的負載設為一個週期，將所述一個週期重複5次。 Then, the load to compress the axial force member 10 by only 1.0% (shortening the distance l by only 25 mm), and secondly, to stretch the axial force member 10 by only 1.0% (to stretch the distance l by only 25 mm) is set as one cycle , Repeat the one cycle 5 times.
接著，最後將使軸向力構件10壓縮僅2.0%(將距離l縮短僅50mm)，其次，使軸向力構件10拉伸僅2.0%(將距離l拉伸僅50mm)的負載設為一個週期(以下稱為「最終週期」)，重複所述一個週期直至軸向力構件10產生挫屈或斷裂為止。 Then, finally, the compression of the axial force member 10 by only 2.0% (shortening the distance l by only 50 mm), and secondly, the load for stretching the axial force member 10 by only 2.0% (the stretch of the distance l by only 50 mm) is set to one The cycle (hereinafter referred to as the "final cycle") repeats the one cycle until the axial force member 10 buckles or breaks.
如此一來，試驗體1號在重複三次最終週期，並進行第四次拉伸時，軸向力構件10產生斷裂。 In this way, when the test body No. 1 was repeated three times in the final cycle and was stretched for the fourth time, the axial force member 10 was broken.
在圖4(b)中，試驗體2號與試驗體1號同樣，在重複三次最終週期，並進行第四次拉伸時，軸向力構件10產生斷裂。 In FIG. 4 (b), the test body No. 2 is the same as the test body No. 1. When the final cycle is repeated three times and the fourth stretching is performed, the axial force member 10 breaks.
即，試驗體1號及試驗體2號均顯示如下情況：由於軸向力構件10未發生挫屈，故而藉由加強管20及強化材料50，使得軸向力構件10的面外變形受到限制。 That is, both test body No. 1 and test body No. 2 show the following: Since the axial force member 10 does not collapse, the out-of-plane deformation of the axial force member 10 is restricted by the reinforcing tube 20 and the reinforcing material 50 .
圖5是表示用以對作為比較材料的現有補強構件的性能進行確認的負載試驗的結果的荷重-應變線圖。負載試驗是與試驗體1號、試驗體2號同樣地，交替地反覆賦予軸向力構件10的壓縮及拉伸的雙擺動負載。 FIG. 5 is a load-strain diagram showing the results of a load test to confirm the performance of a conventional reinforcing member as a comparative material. The load test is a double-oscillating load that alternately compresses and stretches the axial force member 10 in the same manner as the test body No. 1 and the test body No. 2.
在圖5中，試驗體3號在進行一個週期的0.1%的壓縮及拉伸，兩個週期的0.25%的壓縮及拉伸、以及兩個週期的0.5%的壓縮及拉伸的負載之後，進行1.0%的壓縮時，軸向力構件910發生挫屈。 In Figure 5, test body No. 3 is subjected to a load of 0.1% compression and stretching in one cycle, 0.25% compression and stretching in two cycles, and 0.5% compression and stretching in two cycles. When 1.0% compression is performed, the axial force member 910 collapses.
因此，已確認，本發明的強化材料50是即使與現有補強構件900的套筒970相比，彎曲耐力亦高的(大的)補強構件。 Therefore, it has been confirmed that the reinforcing material 50 of the present invention is a (large) reinforcing member having a higher bending resistance than the sleeve 970 of the conventional reinforcing member 900.
圖6(a)及圖6(b)是說明本發明的實施形態2的補強構件的圖，圖6(a)是側視圖，圖6(b)是主要部分的側視剖面圖。再者，對與實施形態1相同的部分或者相當的部分標註相同的符號，並且省略一部分的說明。各構件的相對大小或板厚等並不限定於所圖示的尺寸。 6 (a) and 6 (b) are diagrams illustrating a reinforcing member according to Embodiment 2 of the present invention, FIG. 6 (a) is a side view, and FIG. 6 (b) is a side cross-sectional view of a main part. In addition, the same parts as those in Embodiment 1 or the corresponding parts are denoted by the same symbols, and a part of the description is omitted. The relative size, plate thickness, etc. of each member are not limited to the illustrated dimensions.
在圖6(a)及圖6(b)中，補強構件200包括：軸向力構件10；加強管20，軸向力構件10所貫穿，用以包圍軸向力構件10而對軸向力構件10的面外變形進行限制；卡口230，設置有軸向力構件10的長度方向上的一個端部11a及加強管20的長度方向上的一個端部21a；卡口U形夾40，以朝向與軸向力構件10及加強管20相反的方向突出的方式而設置於卡口230，成為用以設置於建築構造物(未圖示)上的接口；強化材料250，設置有軸向力構件10的長度方向上的另一個端部11b；以及強化材料U形夾60，以朝向與軸向力構件10相反的方向突出的方式而設置於強化材料250，成為用以設置於建築構造物(未圖示)上的接口。 In FIG. 6 (a) and FIG. 6 (b), the reinforcing member 200 includes: an axial force member 10; a reinforcing tube 20 through which the axial force member 10 penetrates to surround the axial force member 10 against the axial force The out-of-plane deformation of the member 10 is restricted; the bayonet 230 is provided with one end 11a in the longitudinal direction of the axial force member 10 and one end 21a in the longitudinal direction of the reinforcing tube 20; the bayonet U-shaped clip 40, The bayonet 230 is provided so as to protrude in the direction opposite to the axial force member 10 and the reinforcement tube 20, and becomes an interface for installation on a building structure (not shown); the reinforcing material 250 is provided with an axial direction The other end portion 11b of the force member 10 in the longitudinal direction; and the reinforced material U-shaped clip 60 are provided on the reinforced material 250 so as to protrude in a direction opposite to the axial force member 10, and are used for installation in the building structure Interface on objects (not shown).
即，在補強構件200的卡口230及強化材料250上，並未形成分別形成於補強構件100(實施形態1)的卡口30的外表面及強化材料50的外表面上的錐形部30c及錐形部50c。而且，除了該點以外，補強構件200與補強構件100相同。 That is, the tapered portion 30c formed on the outer surface of the bayonet 30 of the reinforcing member 100 (Embodiment 1) and the outer surface of the reinforcing material 50 are not formed on the bayonet 230 and the reinforcing material 250 of the reinforcing member 200, respectively And the tapered portion 50c. Except for this point, the reinforcing member 200 is the same as the reinforcing member 100.
因此，補強構件200與補強構件100同樣，經強化材料250強化的加強管20對軸向力構件10的面外變形進行限制，因此彎曲耐力升高(增大)，並且製造成本變得便宜。 Therefore, in the reinforcement member 200, as in the reinforcement member 100, the reinforcement tube 20 reinforced with the reinforcement material 250 restricts the out-of-plane deformation of the axial force member 10, so the bending endurance increases (increases), and the manufacturing cost becomes cheap.
即，當分別澆鑄卡口230及強化材料250時，模具變得簡單。又，可藉由鋼管彼此的焊接接合、或鋼管與圓板(或者形成有中心孔的圓盤)的焊接接合來便宜地製造。 That is, when the bayonet 230 and the reinforcing material 250 are cast separately, the mold becomes simple. In addition, it can be manufactured inexpensively by welding joints between steel pipes or welding joints between steel pipes and a circular plate (or a disc with a central hole).
圖7(a)及圖7(b)是說明本發明的實施形態3的補強構件的圖，圖7(a)是側視圖，圖7(b)是主要部分的側視剖面圖。再者，對與實施形態1相同的部分或者相當的部分標註相同的符號，並且省略一部分的說明。各構件的相對大小或板厚等並不限定於所圖示的尺寸。 7 (a) and 7 (b) are diagrams illustrating a reinforcing member according to Embodiment 3 of the present invention. FIG. 7 (a) is a side view, and FIG. 7 (b) is a side cross-sectional view of a main part. In addition, the same parts as those in Embodiment 1 or the corresponding parts are denoted by the same symbols, and a part of the description is omitted. The relative size, plate thickness, etc. of each member are not limited to the illustrated dimensions.
在圖7(a)及圖7(b)中，補強構件300包括：軸向力構件10；加強管20，軸向力構件10所貫穿，用以包圍軸向力構件10而對軸向力構件10的面外變形進行限制；一側強化材料350a，設置有軸向力構件10的長度方向上的一個端部11a及加強管20的長度方向上的一個端部21a；強化材料U形夾60，以朝向與軸向力構件10及加強管20相反的方向突出的方式而設置於一側強化材料350a，成為用以設置於建築構造物(未圖示)上的接口；另一側強化材料350b，設置有軸向力構件10的長度方向上的另一個端部11b及加強管20的長度方向上的另一個端部21b；以及強化材料U形夾60，以朝向與軸向力構件10及加強管20相反的方向突出的方式而設置於另一側強化材料350b，成為用以設置於建築構造物(未圖示)上的接口。 In FIGS. 7 (a) and 7 (b), the reinforcing member 300 includes: an axial force member 10; a reinforcing tube 20 through which the axial force member 10 penetrates to surround the axial force member 10 and oppose the axial force The out-of-plane deformation of the member 10 is restricted; one side of the reinforcing material 350a is provided with one end 11a in the longitudinal direction of the axial force member 10 and one end 21a in the longitudinal direction of the reinforcing tube 20; 60. It is provided on one side of the reinforcement material 350a so as to protrude in the direction opposite to the axial force member 10 and the reinforcement tube 20, and becomes an interface for installation on a building structure (not shown); the other side is reinforced Material 350b, provided with the other end portion 11b in the longitudinal direction of the axial force member 10 and the other end portion 21b in the longitudinal direction of the reinforcement tube 20; and a reinforced material clevis 60 to face the axial force member 10 and the reinforcing tube 20 are provided on the other side of the reinforcing material 350b such that they protrude in the opposite direction, and become an interface for installation on a building structure (not shown).
即，補強構件300中，代替補強構件100(實施形態1) 的卡口30，而包含一側強化材料350a，且一側強化材料350a及另一側強化材料350b與強化材料50相同。 That is, the reinforcing member 300 replaces the reinforcing member 100 (Embodiment 1) The bayonet 30 includes one side reinforcing material 350a, and one side reinforcing material 350a and the other side reinforcing material 350b are the same as the reinforcing material 50.
因此，加強管20的一個端部21a與藉由另一側強化材料350b而強化的另一個端部21b同樣地，藉由一側強化材料350a而強化。而且，除了該點以外，補強構件300與補強構件100相同。 Therefore, one end 21a of the reinforcing tube 20 is strengthened by the one-side reinforcing material 350a in the same manner as the other end 21b strengthened by the other-side reinforcing material 350b. Except for this point, the reinforcing member 300 is the same as the reinforcing member 100.
因此，補強構件300由於經一側強化材料350a及另一側強化材料350b強化的加強管20對軸向力構件10的面外變形進行限制，故而彎曲耐力升高(增大)，並且製造成本變得便宜。 Therefore, in the reinforcing member 300, the reinforcing tube 20 strengthened by the one-side reinforcing material 350a and the other-side reinforcing material 350b restricts the out-of-plane deformation of the axial force member 10, so the bending endurance increases (increases) and the manufacturing cost Become cheap.
即，由於不需要製造卡口30，故而不需要用以澆鑄卡口30的模具，並且構成補強構件300的零件的種類變少，因此庫存管理變得容易。 That is, since it is not necessary to manufacture the bayonet 30, a mold for casting the bayonet 30 is not necessary, and the types of parts constituting the reinforcing member 300 are reduced, so inventory management becomes easy.
再者，補強構件300包含一對強化材料50，但亦可包含一對強化材料250來代替強化材料50。 Furthermore, the reinforcing member 300 includes a pair of reinforcing materials 50, but a pair of reinforcing materials 250 may be included instead of the reinforcing materials 50.
根據本發明，能夠以簡單的構造來獲得彎曲耐力高的(大的)補強構件，因此亦可對具有各種形態的剖面形狀的軸向力構件進行應用，故而可廣泛用作可因應建築構造物的各種要求的各種補強構件。 According to the present invention, a (large) reinforcing member having high bending resistance can be obtained with a simple structure, and therefore it can also be applied to axial force members having various forms of cross-sectional shapes, so it can be widely used as a building structure Reinforcement components of various requirements.
