Description

一种介于预制钢筋混凝土结构体之间的连接结构及用于该钢筋混凝土结构体的钢筋配置方法Connection structure between prefabricated reinforced concrete structures and steel bar configuration method for the reinforced concrete structures 技术领域Technical field
本发明是关于一种提供多种连接混凝土结构体的技术，特别是针对各种预制或预铸元件可于工地快速组装的连接技术。The present invention relates to a technology for providing a variety of connecting concrete structures, in particular to a connecting technology for various prefabricated or precast elements that can be quickly assembled on site.
发明背景Background of the invention
传统的钢筋混凝土结构墙，柱结构体包括纵向钢筋(例如：金属钢条)与开放型式(open)拉筋和封闭(close)箍筋(tie)，该拉筋与箍筋垂直于纵向钢筋且以一距离间隔设置形成柱状。箍筋与拉筋的主要目的在于横向束制纵向钢筋。常见箍筋的柱状结构为正方体和长方体。In a traditional reinforced concrete structure wall, the column structure includes longitudinal steel bars (for example, metal steel bars), open ties and close ties, which are perpendicular to the longitudinal steel bars and They are arranged at intervals to form a columnar shape. The main purpose of stirrups and braces is to bundle longitudinal steel bars transversely. The columnar structure of common stirrups is cube and cuboid.
对于圆形箍筋柱，闭合形式的箍筋是一个圆形造型。另一种用来替代圆形闭合式箍筋则是连续的螺旋螺纹钢筋。对于圆形箍筋柱来说，许多研究和文献表示利用连续的螺旋螺纹钢筋，相较利用圆形闭合式箍筋，其具有更高的强度与延展性。For a circular stirrup column, the closed form of the stirrup is a circular shape. Another alternative to circular closed stirrups is continuous spiral threaded steel bars. For circular stirrup columns, many studies and documents indicate that the use of continuous spiral rebar has higher strength and ductility than the use of circular closed stirrups.
对于钢筋混凝土的墙体来说，纵向钢筋多使用拉筋和封闭箍筋约束，没有使用螺旋钢筋箍筋作为约束或连接预制件。习知的预制钢筋混凝土结构体采用与现浇混凝土结构相似的钢筋设计，纵向钢筋由拉筋和封闭箍筋所环绕。For reinforced concrete walls, the longitudinal steel bars are mostly restrained by tie bars and closed stirrups, and spiral reinforcement stirrups are not used as restraints or connection prefabs. The conventional precast reinforced concrete structure adopts a steel bar design similar to the cast-in-situ concrete structure, and the longitudinal steel bars are surrounded by ties and closed stirrups.

上述***的缺点在于需要现场建置模板以及固设钢筋，进而拖慢施工时间。因此，如何改良现有接合混凝土结构体技术是需要的，特别对于大楼施工可以舍弃现场建置模板而增加施工速度的改良技术。The disadvantage of the above system lies in the need to build templates and fix steel bars on site, which slows down the construction time. Therefore, how to improve the existing technology of joining concrete structures is needed, especially for building construction, the improved technology that can abandon the on-site construction template and increase the construction speed.

具体实施方式detailed description
图1A，1B及1C所示为两预制墙面的连接示意图。图1A为预制墙面A和B的俯视图：图1B为预制墙面A和B立体图。所述两个预制墙面可以是独立的预制壁板(panel)或是两个相邻预制结构模块的侧墙墙面.亦或是，其他预制结构例如组件、柱、梁、地板或台面等结构体。螺旋式的钢筋连接件1和2分别浇注于所述两预制混凝土结构体的一端并与预制混凝土结构体同高。图中以螺旋形状绘制，本案具有通常技艺人士知悉任何具有周期性连发样式的连接件皆可适用，例如W形状或正弦形状等。所述螺旋式的钢筋连接件或其他连发样式的连接件自预制墙面延伸，并于混凝土结构体一侧形成一连续的空洞。螺旋的几何形状由其直径、螺距和旋转方向所界定。Figures 1A, 1B and 1C show the connection diagrams of two prefabricated walls. Figure 1A is a top view of prefabricated walls A and B; Figure 1B is a three-dimensional view of prefabricated walls A and B. The two prefabricated walls can be independent prefabricated panels or side walls of two adjacent prefabricated structural modules. Or, other prefabricated structures such as components, columns, beams, floors or countertops, etc. Structure. Spiral steel reinforcement connectors 1 and 2 are respectively cast on one end of the two precast concrete structures and have the same height as the precast concrete structures. The figure is drawn in a spiral shape. In this case, those skilled in the art know that any connector with a periodic burst pattern is applicable, such as a W shape or a sinusoidal shape. The spiral steel bar connector or other continuous-fired connector extends from the prefabricated wall and forms a continuous cavity on one side of the concrete structure. The geometry of the spiral is defined by its diameter, pitch and direction of rotation.
如图1A所示，螺旋式的钢筋连接件1和2的部分外露于两预制墙面6的端部。如 果结构体需要强度强度时，可设置纵向钢筋7(例如：钢筋条(Rebar))于螺旋式钢筋连接件1,2中，然而此设置非绝对必要的。在施工场内，两预制墙面A和B的端部相互对应设置，端部的设计样式对应两者连接的需要，且只会在端部间的表面外形成一个大约20毫米的间隔3的间隙。两预制墙面的端部间另会形成一空间5，其空间大小对应于第三螺旋连接件4自预制墙面的端部的上方***所需要的大小。第三螺旋连接件4的直径可选择地小于部分浇注(cast)于预制墙面的螺旋式钢筋连接件1,2，让第三螺旋连接件4得以插设于两预制墙面之间的空间。As shown in Fig. 1A, parts of the spiral steel reinforcement connectors 1 and 2 are exposed at the ends of the two prefabricated walls 6. If the structure requires strength, longitudinal reinforcement 7 (for example: Rebar) can be installed in the spiral reinforcement connector 1,2, but this setting is not absolutely necessary. In the construction site, the ends of the two prefabricated walls A and B are set corresponding to each other. The design style of the ends corresponds to the need for connection between the two, and only a space of about 20 mm 3 is formed outside the surface between the ends. gap. A space 5 is formed between the ends of the two prefabricated walls, and the size of the space corresponds to the size required for the third screw connector 4 to be inserted above the ends of the prefabricated wall. The diameter of the third screw connector 4 can be optionally smaller than the spiral steel reinforcement connector 1 and 2 partially cast on the prefabricated wall, so that the third screw connector 4 can be inserted in the space between the two prefabricated walls .
螺旋连接件4具有和螺旋式钢筋连接件1,2一样的旋转方向以及一样的螺距(然而，螺旋式钢筋连接件1,2是可以具有较大的螺距，以使得作为彼此螺旋连接时可以有较大的间距)。值得注意的是，只要是可以旋转进入螺旋式钢筋连接件1,2的任何螺旋形式的螺旋连接件4皆可适用。螺旋的属性样式，只要螺旋连接件4可以向下旋转***孔洞而不会阻碍到其他钢筋，皆可选择对应的选转方向与螺距。The screw connection 4 has the same rotation direction and the same pitch as the screw connection 1 and 2 (however, the screw connection 1 and 2 can have a larger screw pitch, so that it can be used as a screw connection. Larger spacing). It is worth noting that as long as it is a spiral connection piece 4 in any spiral form that can rotate into the spiral reinforcement connection piece 1,2, it is applicable. For the attribute style of the spiral, as long as the spiral connector 4 can be rotated downward and inserted into the hole without obstructing other steel bars, the corresponding direction and pitch of the rotation can be selected.
两预制墙面之间的间隔3可选择性地通过填缝条或其他手段密封后，空间5透过浇注混凝土或灌浆来完成结构体的连接。值得注意的，此手段不涉及到模板作业，可以加速施工的速度。After the space 3 between the two prefabricated walls can be selectively sealed by caulking strips or other means, the space 5 is connected by pouring concrete or grouting to complete the structure. It is worth noting that this method does not involve formwork operations and can speed up the construction speed.
图1所示的连接也适用于连接有角度交接的预制钢筋混凝土结构体。进一步的，图1的连接也可以应用到多于两个结构体的连接，例如集成多个墙面单元(wall element)。螺旋钢筋自各墙面单元的端部部分外露，浇注的方法使外露于墙面的螺旋钢筋不会阻碍后续螺旋连接钢筋的***；最后一个螺旋连接件于施工现场以向下旋转***结构体所形成的空间，当螺旋连接件***至最底部时，空间5通过浇注混凝土或是灌浆来完成结构体的连接。The connection shown in Figure 1 is also suitable for connecting precast reinforced concrete structures with angled junctions. Further, the connection of FIG. 1 can also be applied to the connection of more than two structural bodies, for example, integrating multiple wall elements. The spiral steel bars are exposed from the end of each wall unit. The method of pouring makes the spiral steel bars exposed on the wall not obstruct the insertion of the subsequent spiral connection steel bars; the last spiral connector is inserted into the structure by rotating downwards at the construction site. When the screw connector is inserted to the bottom, the space 5 is completed by pouring concrete or grouting to complete the connection of the structure.
图1所示的连接其优势在于让两预制墙面间和其他混凝土结构体的垂直连接可以不需要模板。只会于灌浆前需要密封的小空隙间隔3而已。更着，互相扣住的螺旋钢筋可以在混凝土连接受到挤压和外力时提供一个制约限制，增加强度。The advantage of the connection shown in Figure 1 is that the vertical connection between the two prefabricated walls and other concrete structures does not require formwork. Only the small gap space 3 that needs to be sealed before grouting. What's more, the interlocking spiral steel bars can provide a restriction and increase the strength when the concrete connection is subjected to extrusion and external force.
如图2所示，浇注于预制单元的周期性钢筋是通过弯曲(bent)一个连续(continuous)钢筋条至W形状。被弯曲而形成W形状1的钢条被浇注于预制墙面单元A,B之中，其根据墙面的长度设置，优选地与墙面等高。部分W形状的钢条突出于预制墙面单元中，外露的钢条则间隔式地与混凝土表面形成多个空间4。W形状的钢条可以通过焊接方式于墙面单元内形成一纵向钢筋(longitudinal reinforcement)来加强锚固。墙面单元A和墙面单元B于工地放置后会形成一空间6，W形状钢条延伸至所述空间6之中。螺旋连接件3自墙面的顶端以向下旋转作动***于所述的空间6内。由于W形状的钢条被弯折与设置，螺旋连接件3的收合路径(sweeping path)可以穿过W形状的钢条与混凝土所形成的空间4。当螺旋连接件3***至底部后，空间6则通过混凝土浇注或是灌浆来完成连接工作。As shown in Figure 2, the periodic steel bars poured in the precast unit are bent to a W shape by a continuous steel bar. The steel bars bent to form the W shape 1 are cast in the prefabricated wall units A and B, which are set according to the length of the wall, preferably the same height as the wall. Part of the W-shaped steel bars protrude from the prefabricated wall unit, and the exposed steel bars form multiple spaces 4 with the concrete surface at intervals. The W-shaped steel bar can be welded to form a longitudinal reinforcement (longitudinal reinforcement) in the wall unit to strengthen the anchoring. After the wall unit A and the wall unit B are placed on the construction site, a space 6 is formed, and the W-shaped steel bar extends into the space 6. The screw connector 3 is inserted into the space 6 by rotating downward from the top of the wall. Since the W-shaped steel bar is bent and arranged, the sweeping path of the spiral connector 3 can pass through the space 4 formed by the W-shaped steel bar and concrete. After the screw connector 3 is inserted to the bottom, the space 6 is connected by concrete pouring or grouting.
图2示意多种连接的应用，其可以用不同角度来连接元件，也可以是T型接合。借此可以清楚发现，此连接方式可以轻易的接合两个或多个元件，其优势在于不需要工地建设模板。只需要在灌浆前密封间隔3的小空隙而已。Figure 2 illustrates the application of multiple connections, which can connect components at different angles, or T-joints. It can be clearly found that this connection method can easily join two or more components, and its advantage is that it does not require a construction site template. It is only necessary to seal the small gap of interval 3 before grouting.
如图3A与3B所示，多个纵向钢筋2焊接在螺旋钢筋1的***以形成一螺旋钢筋组件3，图中所示螺旋钢筋组件3具有四个纵向钢筋2。所述螺旋钢筋组件3根据结构体 的需要对应适合的位置浇注于预制墙面之中。一般来说，结构体计算于墙体的端部会需要较多螺旋钢筋组件，设置于墙面中段部份的螺旋钢筋组件间距可以较大。螺旋钢筋组件3的多个纵向钢筋2将会成为预制墙面的主要钢筋，其通过焊接受螺旋钢筋束制，因此不再需要其他的拉筋或箍筋约束纵向钢筋2。预制墙面元件于生产时，其可通过使用一可以取出的模具或填充物料或其他适合的手段于浇注时，如图3C切面1-1所示，让螺旋钢筋组件3的空洞4仍保持空洞而不会填有混凝土。As shown in FIGS. 3A and 3B, a plurality of longitudinal steel bars 2 are welded on the periphery of the spiral steel bar 1 to form a spiral steel bar assembly 3. As shown in the figure, the spiral steel bar assembly 3 has four longitudinal steel bars 2. The spiral steel bar assembly 3 is poured into the prefabricated wall at a suitable position according to the needs of the structure. Generally speaking, the structure requires more spiral reinforcement components at the end of the wall, and the spacing between the spiral reinforcement components in the middle of the wall can be larger. The multiple longitudinal steel bars 2 of the spiral steel bar assembly 3 will become the main steel bars of the prefabricated wall, which are bundled by the spiral steel bars by welding, so other ties or stirrups are no longer needed to constrain the longitudinal steel bars 2. When the prefabricated wall element is produced, it can be poured by using a removable mold or filling material or other suitable means, as shown in section 1-1 of Figure 3C, so that the cavity 4 of the spiral steel component 3 remains hollow. It will not be filled with concrete.
图3B所示两种螺旋钢筋连接件，用作连接预制件。第一种是单螺旋钢筋连接件，使纵向钢筋6焊接于一个螺旋钢筋5的内侧。第二种为双螺旋连接件，纵向钢筋10被置于两个以旋转角度180°分隔螺旋互扣的螺旋钢筋8，9之中并焊接于其内侧。如图3C 2-2切面所示，连接件螺旋钢筋5的直径设计为略小于螺旋钢筋组件3，但与螺旋钢筋组件3具有一样的螺距。故此于吊装前，能如图3C左图所示用旋转的方式将螺旋连接件转入上部预制墙的主要螺旋空洞4的底部，完全隐藏于空洞4之中。上部的预制墙吊装时，使其空洞4与一下部有相似钢筋结构的预制墙顶部的空洞4进行对位。施工人员可以将工具8***上部预制墙的空洞4，或其他方法控制螺旋连接件5向下旋转使螺旋连接件的一半移动至下部预制墙的主要螺旋钢筋组件之中，然后注浆或浇注混凝土填满空洞4。水泥浆或混凝土凝固后，上部与下部预制墙的纵向钢筋2和纵向钢筋6的搭接，以及螺旋钢筋1和螺旋钢筋5的重叠，形成有效的结构作用来传递上部与下部预制墙纵向钢筋2的内力。螺旋连接件5更进一步的穿过至上、下预制墙的连接处，其可以增强连接处的剪力耐受强度。Figure 3B shows two types of spiral reinforcement connectors, which are used to connect preforms. The first type is a single spiral steel bar connector, which welds the longitudinal steel bar 6 to the inner side of a spiral steel bar 5. The second type is a double helix connection. The longitudinal steel bars 10 are placed in two spiral steel bars 8, 9 separated by a rotation angle of 180°, and welded to the inside. As shown in the section 2-2 of Fig. 3C, the diameter of the connecting piece spiral reinforcement 5 is designed to be slightly smaller than the spiral reinforcement assembly 3, but has the same pitch as the spiral reinforcement assembly 3. Therefore, before hoisting, the spiral connector can be rotated into the bottom of the main spiral cavity 4 of the upper prefabricated wall in a rotating manner as shown in the left picture of FIG. 3C, and is completely hidden in the cavity 4. When the upper precast wall is hoisted, the cavity 4 is aligned with the cavity 4 on the top of the lower precast wall with similar steel structure. The construction staff can insert the tool 8 into the cavity 4 of the upper precast wall, or control the screw connector 5 to rotate downward to move half of the screw connector to the main spiral steel component of the lower precast wall, and then grouting or pouring concrete Fill the hole 4. After the cement slurry or concrete is solidified, the overlap of the longitudinal reinforcement 2 and the longitudinal reinforcement 6 of the upper and lower precast walls, and the overlap of the spiral reinforcement 1 and the spiral reinforcement 5, form an effective structural function to transfer the longitudinal reinforcement 2 of the upper and lower precast walls Internal force. The screw connection member 5 further penetrates the connection between the upper and lower prefabricated walls, which can enhance the shear resistance strength of the connection.
图3A至3C所示的连接其优势在于不需要任何模板，螺旋钢筋组件已经对纵向钢筋提供侧向束制，因此可以避免或降低需要密集人力处理的箍筋作业。螺旋钢筋组件可以透过工厂自动化来进行生产，特别是通过使用焊接机器人。过去，墙面或柱体的水平接合处的抗剪强度是偏弱的，因为只有垂直钢筋的连接。本案创新的利用螺旋钢筋穿过连接处的结果，可以增强连接处的抗剪强度，适合应用于地震带区域。The advantage of the connection shown in Figures 3A to 3C is that it does not require any formwork, and the spiral steel bar component has provided lateral binding to the longitudinal steel bars, so it can avoid or reduce the stirrup operations that require intensive manpower processing. Spiral steel components can be produced through factory automation, especially by using welding robots. In the past, the shear strength of the horizontal joints of walls or columns was weak, because only vertical steel bars were connected. In this case, the innovative use of spiral steel bars passing through the joints can enhance the shear strength of the joints and is suitable for use in seismic zones.
图4示意两预制楼板的接合，实质上类似两个预制墙面以水平方式接合成板，但有做一些调整。预制板A和预制板B留有一个小间隔1相邻放置,大约20毫米的距离。螺旋连接组件包括焊接有纵向钢筋2的螺旋钢筋3，该设计与图3C的设计类似，也可以用单螺旋或双螺旋连接件设计。图4所示，预制楼板的边缘以适当的间距7形成有多个空洞空间4。各空洞空间4被设计具有足够大的空间来放置螺旋连接组件。其中一边的预制板具有较深的空洞空间，其深度足以暂时存放置螺旋连接组件即可。Figure 4 illustrates the joining of two prefabricated floor slabs, which is essentially similar to joining two prefabricated walls in a horizontal manner to form a slab, with some adjustments. The prefabricated board A and the prefabricated board B are placed next to each other with a small space 1 at a distance of about 20 mm. The spiral connection component includes a spiral steel bar 3 welded with longitudinal steel bars 2. The design is similar to the design of FIG. 3C, and a single screw or double screw connection design can also be used. As shown in FIG. 4, the edge of the prefabricated floor slab is formed with a plurality of hollow spaces 4 at appropriate intervals 7. Each hollow space 4 is designed to have a large enough space to place the screw connection components. The prefabricated board on one side has a relatively deep hollow space, which is deep enough to temporarily store the screw connection components.
一线材5或是其他连接组件牢固的绑在螺旋连接件的一端，另一端则延伸至两预制板间的间隙。当预制板定位后，预制板A和预制板B的空洞空间4相互匹配与面对面。通过拉扯线材5或其他方法来让螺旋连接件移动至对面预制板之中。于最终位置，螺旋连接件等长6嵌入于两预制板之中。螺旋连接组件完成定位后，接着将浆液填满间隔与空洞空间来完成结构体的连接。完成连接后，螺旋连接组件的纵向钢筋能承受连接处的弯矩，而螺旋钢筋则会承受连接处的剪力。图4所示的连接不需要任何模板，只需要在灌浆前密封小空隙间隔即可。A wire 5 or other connecting component is firmly tied to one end of the screw connection, and the other end extends to the gap between the two prefabricated plates. After the prefabricated board is positioned, the hollow spaces 4 of the prefabricated board A and the prefabricated board B match and face each other. Pull the wire 5 or other methods to move the screw connector to the opposite prefabricated board. In the final position, the screw connector 6 is embedded in the two prefabricated plates. After the screw connection components are positioned, the gaps and void spaces are filled with slurry to complete the connection of the structure. After the connection is completed, the longitudinal reinforcement of the spiral connection component can bear the bending moment at the connection, and the spiral reinforcement will bear the shear force at the connection. The connection shown in Figure 4 does not require any template, only small gaps need to be sealed before grouting.
如图5-9所示，其示意有本发明更一步的范畴，此实施例为预制墙面A与预制墙面B以面对面的方式连接。预制墙面的内墙面(internal face)面对面设置。于预制程序中，如图6透视图与图7俯瞰切图所示，多个空洞1形成于内墙面上，根据结构体的设计 需求，各空洞1以适当的间距来设置。空洞1可由半圆形或其他剖面形状形成，并沿着预制墙面的高度垂直延伸。预制墙面A的空洞对应于预制墙面B的空洞，两空洞面对面形成一个沿着墙高的连续通道。As shown in Figures 5-9, which illustrate the further scope of the present invention, in this embodiment, the prefabricated wall A and the prefabricated wall B are connected in a face-to-face manner. The internal faces of the prefabricated walls are set face to face. In the prefabrication process, as shown in the perspective view of FIG. 6 and the top view of FIG. 7, a plurality of cavities 1 are formed on the inner wall. According to the design requirements of the structure, the cavities 1 are arranged at appropriate intervals. The cavity 1 can be formed by a semicircle or other cross-sectional shapes, and extends vertically along the height of the prefabricated wall. The cavity of prefabricated wall A corresponds to the cavity of prefabricated wall B, and the two cavities face each other to form a continuous passage along the height of the wall.
如图5所示，被弯曲至W型的钢筋条浇注于预制墙的前述连续通道1中，并有部分弯折钢筋条伸出预制墙外。W形状的钢筋条通过嵌入的方式牢固锚定地设置于预制混凝土中。另外，为了取得锚固，W形状的钢筋条更可于预制墙身中焊接纵向钢筋筋3。W形状的钢筋条与预制墙的内墙面形成三角形的空洞，W形状的钢筋条的属性由宽度(width)与齿距(pitch)来定义。As shown in Figure 5, the steel bars bent to the W shape are cast in the aforementioned continuous channel 1 of the precast wall, and some of the bent steel bars extend outside the precast wall. The W-shaped steel bars are firmly anchored in the precast concrete by embedding. In addition, in order to obtain anchorage, W-shaped steel bars can be welded with longitudinal steel bars 3 in the precast wall body. The W-shaped steel bar and the inner wall of the prefabricated wall form a triangular cavity. The properties of the W-shaped steel bar are defined by width and pitch.
在预制墙面正确地设置于施工场地的位置之后，如图5和8所示，与预制墙面等高的螺旋钢筋以旋转作动的方式从墙面的顶部***穿孔2。螺旋钢筋的螺距与W形状的钢筋条的齿距相同。螺旋形状的直径被设计能够让螺旋钢筋穿过形成于W形状的外露钢筋条与预制墙面的内墙面间的三角形的空洞2。预制墙面A和预制墙面B的W形状的钢筋条呈现一种交错形式，以供螺旋钢筋向下前进时，螺旋钢筋可以穿过两墙面的所有三角形的空洞2。因此，螺旋钢筋和W形状的钢筋条不一定会碰触到彼此，但两者形成交扣的样式。After the prefabricated wall is correctly set at the location of the construction site, as shown in Figures 5 and 8, the spiral steel bars with the same height as the prefabricated wall are inserted into the perforation 2 from the top of the wall in a rotating manner. The pitch of the spiral steel bar is the same as the pitch of the W-shaped steel bar. The diameter of the spiral shape is designed to allow the spiral steel bar to pass through the triangular cavity 2 formed between the exposed steel bar of the W shape and the inner wall of the prefabricated wall. The W-shaped steel bars of the prefabricated wall A and the prefabricated wall B present a staggered form, so that when the spiral steel bars advance downward, the spiral steel bars can pass through all the triangular holes 2 of the two walls. Therefore, the spiral steel bar and the W-shaped steel bar may not touch each other, but they form an interlocking style.
当螺旋钢筋进入到墙面的底部后，混凝土浇注或注浆至穿孔3和填满所有的空洞。待混凝土或浆液硬化后，结构体的内力得以通过坚固的混凝土或浆液从螺旋钢筋传送到W形状的钢筋里。如此一来，两预制墙面A和B可以共同承受结构体的荷载，其结构性能相当于同两个墙体合计厚度的现浇钢筋混凝土墙体。After the spiral steel bar enters the bottom of the wall, the concrete is poured or grouted to the perforation 3 and fill all the cavities. After the concrete or grout is hardened, the internal force of the structure can be transmitted from the spiral steel bar to the W-shaped steel bar through the strong concrete or grout. In this way, the two prefabricated walls A and B can jointly bear the load of the structure, and their structural performance is equivalent to the cast-in-situ reinforced concrete wall with the combined thickness of the two walls.
本案新的连接方法可用于连接两个以上的墙面，如图9所示的实施例，本实施例有四个墙面A,B,C,D。预制墙A和预制墙B并排设置，预制墙C和预制墙D并排设置。该些预制墙是一个完整墙面的组合部件，其透过上述的接合方法或是其他手段。于四个预制墙连接处，其通过螺旋钢筋连接件来移转结构的力。The new connection method in this case can be used to connect more than two wall surfaces. As shown in the embodiment shown in FIG. 9, this embodiment has four wall surfaces A, B, C, and D. Precast wall A and precast wall B are arranged side by side, and precast wall C and precast wall D are arranged side by side. The prefabricated walls are composite parts of a complete wall surface, which are made through the above-mentioned joining method or other means. At the connection of the four prefabricated walls, it transfers the force of the structure through the spiral reinforcement connector.
值得注意的是，穿孔除了可以是圆形以外，其也可以是任何可以形成于预制墙端部并可用注浆填补的形状。被弯折成W形状并浇铸于墙面端部的钢筋条是由工厂所生产，部分W形状的钢筋向外延伸至穿孔中。于各墙面的W形状钢筋具有与对应墙面相同一致的齿距，或是对应墙面齿距的倍数或分数比例的齿距，以供形成空洞让各W形状的钢筋可以相互连接。It is worth noting that, in addition to being circular, the perforation can also be any shape that can be formed at the end of the precast wall and filled with grouting. The steel bars bent into a W shape and cast on the end of the wall are produced by the factory, and part of the W-shaped steel bars extend outward into the perforations. The W-shaped steel bars on each wall have the same tooth pitch as the corresponding wall, or a tooth pitch corresponding to a multiple or a fraction of the wall tooth pitch, so as to form a cavity so that the W-shaped steel bars can be connected to each other.
于施作工地，四个预制墙放置在一起以形成一个沿着墙高的连续通道。螺旋钢筋连接件的螺距具有与W形状钢筋相同的齿距，并以向下旋转作动的方式***所述连续通道。W形状钢筋于预制墙面所形成的三角型空洞/孔洞与螺旋钢筋连接件的螺距路径匹配。因此，螺旋钢筋得以顺利的进入到墙的底部，以使得即便螺旋钢筋和W形状的钢筋条不一定会碰触到彼此，但螺旋钢筋与四个预制墙的W形状钢筋呈现互扣的样式。At the construction site, four prefabricated walls are placed together to form a continuous passage along the wall height. The screw pitch of the spiral steel bar connector has the same pitch as the W-shaped steel bar, and is inserted into the continuous channel in a downward rotation actuation manner. The triangular cavity/hole formed by the W-shaped steel bar on the prefabricated wall matches the pitch path of the spiral steel connector. Therefore, the spiral steel bar can smoothly enter the bottom of the wall, so that even though the spiral steel bar and the W-shaped steel bar may not touch each other, the spiral steel bar and the W-shaped steel bar of the four precast walls present an interlocking style.
混凝土浇注或注浆至连续的通道和填满所有的空间。结构体的内力得以穿过螺旋钢筋和W形状的钢筋条，借此令四个预制墙结构有效的连接起来。Concrete is poured or grouted into continuous channels and fills up all spaces. The internal force of the structure can penetrate the spiral steel bar and the W-shaped steel bar, thereby effectively connecting the four prefabricated wall structures.
如图10所示，图10描述一个以三个本发明螺旋结构连接的方案。于预制程序中，空洞1形成于混凝土墙的内表面，并根据结构设计需求，空洞1间具有适当的间距。该空洞1可为半圆形或是其他形状，并垂直沿着预制墙的墙高延伸。预制墙A面对具有相似空洞的预制墙B，以形成一个沿着墙高延伸的连续通道。上述的W形状钢筋改为由两个螺旋钢筋6取代，该两个螺旋钢筋6具有相同的高度并分别浇注于预制墙面，并于各螺旋有一 部分延伸出预制墙来凸出于连续通道内。该螺旋钢筋通过嵌入预制混凝土的方式使该螺旋钢筋牢固锚定于预制墙面中。连接螺旋钢筋7与两个螺旋钢筋6互相紧扣。As shown in Fig. 10, Fig. 10 describes a scheme of connecting three spiral structures of the present invention. In the prefabrication process, the cavities 1 are formed on the inner surface of the concrete wall, and according to the structural design requirements, the cavities 1 have an appropriate spacing. The cavity 1 can be semicircular or other shapes, and extends vertically along the height of the prefabricated wall. The precast wall A faces the precast wall B with similar voids to form a continuous channel extending along the wall height. The above-mentioned W-shaped steel bars are replaced by two spiral steel bars 6 which have the same height and are respectively cast on the prefabricated wall, and a part of each spiral extends out of the prefab wall to protrude from the continuous channel . The spiral steel bar is firmly anchored in the precast wall by embedding the precast concrete. The connecting spiral steel bar 7 and the two spiral steel bars 6 are fastened to each other.
如图11所示，螺旋钢筋的属性由其螺距(pitch)与半径(diameter)来定义。当预制墙面于施作工地正确摆放后，一个具有和墙面等高的第三个螺旋钢筋/螺旋连接件7自墙的顶部以旋转作动方式***穿孔之中。浇铸于各墙面的螺旋钢筋具有与第三螺旋钢筋相同一致的螺距，或是呈现倍数的螺距。As shown in Figure 11, the properties of the spiral reinforcement are defined by its pitch and diameter. When the prefabricated wall is correctly placed at the construction site, a third spiral steel bar/screw connector 7 with the same height as the wall is inserted into the perforation in a rotating manner from the top of the wall. The spiral steel bar cast on each wall has the same pitch as the third spiral steel bar, or a multiple of the pitch.
根据上述的设计，第三螺旋钢筋7将不会被第一和第二的螺旋钢筋给阻碍，其可以于通道内穿至预制墙的底部。如图12所示，所述三个螺旋钢筋不一定会相互碰触，但连接螺旋钢筋7与两个螺旋钢筋6互相紧扣。According to the above design, the third spiral steel bar 7 will not be hindered by the first and second spiral steel bars, and it can penetrate to the bottom of the precast wall in the channel. As shown in FIG. 12, the three spiral steel bars may not necessarily touch each other, but the connecting spiral steel bars 7 and the two spiral steel bars 6 are fastened to each other.
图13示意以上的连接方式可连接2个以上，如4个墙体。墙体A与B面对面的放置，墙体C和D也一样。A，B，C，D的端部放置在一起。四个预制墙体于接合处，组合形成可以是圆形或是其他适合的形状的空洞8。四组螺旋钢筋于工厂浇注于墙体A，B，C，D的端部。螺旋钢筋9的部分向外延伸至墙体外凸出于空洞之中。于施工现场，四个墙面放置在一起并且形成沿着墙高的连续通道。一个和螺旋钢筋具有相同螺距螺旋钢筋11以由上向下旋转作动的方式***所述连续通道。浇注于墙面端部的的螺旋钢筋9与一旁螺旋钢筋垂直错开1/4螺距的距离，以使螺旋钢筋连接件11向下穿越，并呈现交错但不会受到阻碍。螺旋钢筋连接件11与四个螺旋钢筋9不一定会相互碰触，但会呈现互扣的样式。Figure 13 shows that the above connection method can connect more than two, such as four walls. Walls A and B are placed face to face, as are walls C and D. Place the ends of A, B, C, and D together. The four prefabricated walls are combined at the joint to form a cavity 8 that can be circular or other suitable shapes. Four sets of spiral steel bars are cast at the end of the wall A, B, C, D at the factory. The part of the spiral steel bar 9 extends outward to protrude into the cavity outside the wall. At the construction site, the four walls are placed together and form a continuous passage along the height of the wall. A spiral steel bar 11 having the same pitch as the spiral steel bar is inserted into the continuous channel in a manner of rotating upward and downward. The spiral steel bars 9 cast on the end of the wall are vertically staggered by a distance of 1/4 pitch from the spiral steel bars on the side, so that the spiral steel bars 11 pass downwards and appear staggered but not hindered. The spiral steel connection piece 11 and the four spiral steel bars 9 may not necessarily touch each other, but they will show an interlocking style.
混凝土浇注或注浆至连续的通道和填满所有的空间。结构体的内力得以穿过该些螺旋钢筋之间，令四个预制墙有效地结构性连接起来。Concrete is poured or grouted into continuous channels and fills up all spaces. The internal force of the structure can penetrate between the spiral steel bars, so that the four precast walls are effectively connected structurally.
以上所述的纵向钢筋与螺旋钢筋可以用其他金属或碳纤维等适当的结构物料条状物代替。The above-mentioned longitudinal steel bars and spiral steel bars can be replaced by other suitable structural materials such as metal or carbon fiber.
