Description

不連續鋼板圍束鋼筋混凝土連接梁Discontinuous steel plate enclosed reinforced concrete connecting beam

本揭露有關於一種不連續鋼板圍束鋼筋混凝土連接梁。The present disclosure relates to a reinforced concrete connecting beam surrounded by discontinuous steel plates.

鋼筋混凝土剪力牆(shear wall)或結構牆(structural wall)，因可提供相當的面內強度與勁度，常設計為抵抗側向力的主要構件，但建築需求有時須沿著牆高度方向作規則開孔，如電梯門開孔或採光窗開孔等，開孔將原先單面牆體分成兩個或數個牆體，而牆體與牆體間則以橫向構件相連，此系統一般稱為耦合剪力牆系統(coupled shear wall system)，而連接牆體間的橫向構件一般稱之為連接梁(coupling beam)。當連接梁淨跨距與梁深比偏低的時候，過去研究顯示需要配置對角線鋼筋使連接梁具有一定韌性。Reinforced concrete shear wall (shear wall) or structural wall (structural wall), because it can provide considerable in-plane strength and stiffness, it is often designed as the main component to resist lateral force, but sometimes the building needs to be along the height of the wall Make regular openings in the direction, such as elevator door openings or lighting window openings. It is generally referred to as a coupled shear wall system, and the transverse members connecting the walls are generally referred to as coupling beams. When the ratio of the net span of the connecting beam to the beam depth is low, past studies have shown that it is necessary to configure the diagonal reinforcement to make the connecting beam have a certain toughness.

梁淨跨距與梁深的比值稱跨深比(aspect ratio)，目前鋼筋混凝土結構設計規範要求低跨深比且高剪力之鋼筋混凝土連接梁須配置對角線鋼筋。雖然研究證實含有對角線鋼筋的鋼筋混凝土梁具有良好的耐震行為，但是對角線鋼筋的施工困難，易造成施工品質下降且不利於工期。其他設計方案也有使用鋼梁取代鋼筋混凝土梁的案例，但是鋼梁需要在其他鋼筋混凝土構件內錨定，而錨定的施工細節並不容易，且鋼梁在施工現場的定位也有精確度的問題，難以普及。The ratio of the net span of the beam to the depth of the beam is called the aspect ratio. The current design specifications for reinforced concrete structures require that reinforced concrete connecting beams with low span-to-depth ratio and high shear force must be equipped with diagonal reinforcement. Although studies have confirmed that reinforced concrete beams containing diagonal steel bars have good seismic behavior, the construction of diagonal steel bars is difficult, which is likely to cause a decline in construction quality and is not conducive to the construction period. Other design schemes also use steel beams to replace reinforced concrete beams, but steel beams need to be anchored in other reinforced concrete components, and the construction details of anchoring are not easy, and the positioning of steel beams on the construction site also has problems with accuracy , difficult to popularize.

因此，需要一種韌性好、施工簡單快捷，且當受到外力作用後能夠在維持建築設計強度的條件下具有最大變形量的連接梁來解決上述遇到的問題。Therefore, there is a need for a connecting beam with good toughness, simple and quick construction, and a maximum deformation amount under the condition of maintaining the architectural design strength when subjected to external force to solve the above-mentioned problems.

在以下描述中，將詳細敘述許多特定細節以使讀者能夠充分理解以下的實施例。然而，可在無此等特定細節之情況下實踐本揭露之實施例。在其他情況下，為簡化圖式，熟知的結構與裝置僅示意性地繪示於圖中。In the following description, numerous specific details are set forth in detail to enable the reader to fully understand the following embodiments. However, embodiments of the present disclosure may be practiced without these specific details. In other instances, well-known structures and devices are shown schematically in the drawings for simplicity of illustration.

第1圖繪示本揭露一比較例之對角線不連續鋼板圍束鋼筋混凝土連接梁10的示意圖。目前規範要求低跨深比且高剪力之鋼筋混凝土連接梁須配置對角線鋼筋。如第1圖所示，鋼筋連接梁結構10包含縱向鋼筋110、全斷面橫向鋼筋120、對角線鋼筋130。研究證實含有對角線鋼筋的鋼筋混凝土連接梁在低跨深比且高剪力需求下確實具有良好的耐震行為，然而，對角線鋼筋的配筋形式於現場施工相當困難。具體的說，對角線鋼筋在梁跨度中央交錯造成鋼筋排列擁擠，且對角線鋼筋必須有一定的伸展長度，因此必須斜向***豎向構件如剪力牆的邊界構材內，要避免鋼筋衝突非常困難，再加上規範對於橫向鋼筋的量與間距都有一定要求，再次造成施工難度增加，進而造成施工品質不佳且耗費工期。FIG. 1 is a schematic diagram of a reinforced concrete connecting beam 10 surrounded by diagonal discontinuous steel plates according to a comparative example of the present disclosure. The current specification requires reinforced concrete connecting beams with low span-to-depth ratio and high shear force to be equipped with diagonal reinforcement. As shown in FIG. 1 , the reinforcing bar connecting beam structure 10 includes longitudinal reinforcing bars 110 , full-section transverse reinforcing bars 120 , and diagonal reinforcing bars 130 . Studies have confirmed that reinforced concrete connecting beams containing diagonal steel bars do have good seismic behavior under low span-to-depth ratio and high shear force requirements. Specifically, the staggered diagonal reinforcement in the center of the beam span causes the reinforcement to be crowded, and the diagonal reinforcement must have a certain extension length, so it must be inserted obliquely into the boundary members of vertical members such as shear walls. Rebar conflict is very difficult, and the specification has certain requirements for the quantity and spacing of transverse reinforcement, which again increases the difficulty of construction, resulting in poor construction quality and time-consuming construction.

In various embodiments, the fixation element 280 includes a screw and a nut. Specifically, the screw rod penetrates through the first ventral steel plate 240 and the second ventral steel plate 250, and both ends of the screw rod are locked with nuts.

請繼續參閱第2圖及第3圖，在多個實施例中，不連續鋼板圍束鋼筋混凝土連接梁20可更包含複數個固定元件290貫穿第一翼側鋼板260及第二翼側鋼板270。在多個實施例中，所述固定元件290包含螺桿和螺帽。具體的說，螺桿貫穿第一翼側鋼板260及第二翼側鋼板270，螺桿的兩端再以螺帽鎖緊。Please continue to refer to FIG. 2 and FIG. 3 , in various embodiments, the discontinuous steel plate surrounding reinforced concrete connecting beam 20 may further include a plurality of fixing elements 290 penetrating the first wing steel plate 260 and the second wing steel plate 270 . In various embodiments, the fixation element 290 includes a screw and a nut. Specifically, the screw rod passes through the first wing steel plate 260 and the second wing steel plate 270, and both ends of the screw rod are locked with nuts.

上述固定元件280/290與多塊鋼板240/250/260/270各自用於提供鋼筋混凝土連接梁腹面與翼面一定量的壓力，例如0.05Ag×fc’至0.1 Ag×fc’，其中Ag為鋼筋混凝土連接梁被圍束面之面積，如就第一表面而言，此處Ag表示第一表面之表面積，fc’ 為混凝土抗壓強度。應注意，本揭露並未限制固定元件的數量。The above-mentioned fixing elements 280/290 and the plurality of steel plates 240/250/260/270 are respectively used to provide a certain amount of pressure on the reinforced concrete connecting beam web and the airfoil, such as 0.05Ag×fc' to 0.1 Ag×fc', where Ag is The area of the enclosed surface of the reinforced concrete connecting beam, such as the first surface, where Ag represents the surface area of the first surface, and fc' is the concrete compressive strength. It should be noted that the present disclosure does not limit the number of fixing elements.

須說明的是，鋼筋混凝土連接梁腹面與翼面各自具有被鋼板覆蓋的一中央區域以及一外圍區域，且此外圍區域環繞中央區域。也就是說，此外圍區域的寬度為2cm至5cm。當不連續鋼板圍束鋼筋混凝土連接梁20在承受往復載重(如地震力作用)下能將損傷集中在外圍區域內。此外，應注意，在滿足結構規範設計要求下，鋼筋混凝土連接梁需有至少一組橫向鋼筋設置於外圍區域(或間隙)內，以確保外圍區域具有足夠的韌性。It should be noted that each of the reinforced concrete connecting beam web and the airfoil has a central area and a peripheral area covered by the steel plate, and the peripheral area surrounds the central area. That is, the width of this peripheral area is 2 cm to 5 cm. When the reinforced concrete connecting beam 20 surrounded by discontinuous steel plates is subjected to reciprocating loads (such as earthquake forces), the damage can be concentrated in the peripheral area. In addition, it should be noted that under the design requirements of the structural code, the reinforced concrete connecting beam needs to have at least one set of transverse steel bars arranged in the peripheral area (or gap) to ensure that the peripheral area has sufficient toughness.

可以理解的是，本揭露的不連續鋼板圍束鋼筋混凝土連接梁20，因其中央區域被鋼板所包覆固定住，相較於外圍區域，此中央區域具有較強的傳力機制，因此當不連續鋼板圍束鋼筋混凝土連接梁20在承受往復載重(如地震力)作用下，此中央區域不易產生明顯的破壞。It can be understood that the discontinuous steel plate-enclosed reinforced concrete connecting beam 20 of the present disclosure has a stronger force transmission mechanism in the central region than the peripheral region because the central region is covered and fixed by the steel plate. Under the action of the reciprocating load (such as seismic force) of the discontinuous steel plate-enclosed reinforced concrete connecting beam 20, the central area is not likely to be significantly damaged.

以下的實驗例係用以詳述本揭露之特定態樣，並使本發明所屬技術領域中具有通常知識者得以實施本發明。然而，以下的實施例不應用以限制本發明。以下，將列舉比較例與實施例以驗證本揭露的功效。The following experimental examples are used to describe specific aspects of the present disclosure in detail, and to enable those skilled in the art to which the present invention pertains to practice the present invention. However, the following examples should not be used to limit the present invention. Hereinafter, comparative examples and examples will be listed to verify the efficacy of the present disclosure.

實驗例:短梁往復載重實驗Experimental example: short beam reciprocating load test

本實驗例利用水平千斤頂提供水平往復位移，用以模擬現實鋼筋混凝土連接梁受力後的情形。第4圖繪示本揭露一實施例之不連續鋼板圍束鋼筋混凝土連接梁20經受力後的測試照片。由第4圖可看出，本揭露實施例之不連續鋼板圍束鋼筋混凝土連接梁經受力測試並移除鋼板後，不連續鋼板圍束鋼筋混凝土連接梁的損壞區域大部分集中於原本鋼板與混凝土牆面之間的間隙處，而被鋼板覆蓋之混凝土牆面部分大致未受損壞。This experimental example uses a horizontal jack to provide a horizontal reciprocating displacement to simulate the actual situation of a reinforced concrete connecting beam under stress. FIG. 4 shows a test photo of the discontinuous steel plate-enclosed reinforced concrete connecting beam 20 subjected to force according to an embodiment of the present disclosure. It can be seen from FIG. 4 that after the discontinuous steel plate-enclosed reinforced concrete connecting beam of the embodiment of the present disclosure is subjected to a force test and the steel plate is removed, most of the damaged areas of the discontinuous steel plate-enclosed reinforced concrete connecting beam are concentrated in the original steel plate. The gap between it and the concrete wall, and the part of the concrete wall covered by the steel plate is largely undamaged.

第5圖繪示本揭露一比較例之對角線不連續鋼板圍束鋼筋混凝土連接梁10經受力後的測試照片。由第5圖可看出，本揭露比較例之不連續鋼板圍束鋼筋混凝土連接梁經歷類似位移歷時後，此不連續鋼板圍束鋼筋混凝土連接梁的損壞為不具規則性且受損程度較廣。FIG. 5 shows a test photo of the reinforced concrete connecting beam 10 surrounded by diagonal discontinuous steel plates of a comparative example of the present disclosure after being subjected to force. It can be seen from FIG. 5 that after the discontinuous steel plate-enclosed reinforced concrete connecting beam of the comparative example of the present disclosure has experienced a similar displacement duration, the damage of the discontinuous steel plate-enclosed reinforced concrete connecting beam is irregular and the damage degree is relatively extensive. .

綜上所述，本揭露的不連續鋼板圍束鋼筋混凝土連接梁以固定元件將四片鋼板設置於鋼筋混凝土連接梁的側邊，以提供側向微壓且連續的圍束條件。各鋼板與混凝土牆面之間所保留的間隙，可以使得建築物在受到不可避免的外力負載(例如，地震)下，將大部分的損傷集中於間隙中。本發明之不連續鋼板圍束鋼筋混凝土連接梁經實驗證實可以在大變形量需求下維持其設計強度。To sum up, the discontinuous steel plates of the present disclosure enclose the reinforced concrete connecting beam with four steel plates arranged on the sides of the reinforced concrete connecting beam by means of fixing elements, so as to provide lateral slight pressure and continuous confinement conditions. The gaps reserved between each steel plate and the concrete wall can cause most of the damage to be concentrated in the gaps when the building is subjected to an unavoidable external force load (eg, earthquake). The discontinuous steel plate surrounding reinforced concrete connecting beam of the present invention has been proved by experiments that it can maintain its design strength under the requirement of large deformation.

雖然本揭露已以實施方式揭露如上，然其並非用以限定本揭露，任何熟習此技藝者，在不脫離本揭露之精神和範圍內，當可作各種之更動與潤飾，因此本揭露之保護範圍當視後附之申請專利範圍所界定者為準。Although the present disclosure has been disclosed as above in embodiments, it is not intended to limit the present disclosure. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure protects The scope shall be determined by the scope of the appended patent application.
