具体实施方式detailed description
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
实施例1Example 1
如图2、图3所示，磁悬浮工程接触轨预埋槽道，包括两个并排安装的槽道本体，所述槽道本体通过连接钢筋相互连接，每个所述槽道本体上均设置有安装孔，这些安装孔的位置一一对应(即，一个槽道本体上安装孔的位置与另一个槽道本体上安装孔的位置在槽道本体长度方向上的投影相互重合，安装孔的位置一一对应)，用于安装固定件与所述轨道梁固定相连。As shown in Figure 2 and Figure 3, the pre-buried channel of the contact rail of the maglev engineering includes two channel bodies installed side by side. The channel bodies are connected to each other through connecting steel bars, and each channel body is provided with Mounting holes, the positions of these mounting holes correspond to each other (that is, the position of the mounting hole on one channel body and the projection of the position of the mounting hole on the other channel body on the length direction of the channel body coincide with each other, and the position of the mounting hole One-to-one correspondence), used to install the fixture and fixedly connect with the track beam.
本实施例中的磁悬浮工程接触轨预埋槽道预埋在轨道梁两侧，如图1A、1B和1C所示，该接触轨安装底座孔间距为125mm(即，这两个槽道本体其安装孔中心轴线所处平面之间的平面间距为125mm)，至少包括4个定位孔(即每个槽道本体上至少有两个安装孔)，每个定位孔的直径均为14mm，满足M12螺栓与接触轨底座的安装。该预埋槽道采用两根槽道并排安装，并采用两根10mm直径的钢筋进行连接固定，使两根槽道在125mm间距下固定不变。The pre-buried channel of the contact rail of the magnetic levitation engineering in this embodiment is pre-embedded on both sides of the track beam, as shown in Figures 1A, 1B and 1C, the hole spacing of the contact rail installation base is 125mm (that is, the two channel bodies The plane spacing between the planes where the central axis of the mounting hole is located is 125mm), including at least 4 positioning holes (that is, there are at least two mounting holes on each channel body), and the diameter of each positioning hole is 14mm, meeting M12 Installation of bolts and contact rail base. The pre-buried channel is installed side by side with two channels, and is connected and fixed by two steel bars with a diameter of 10mm, so that the two channels are fixed at a distance of 125mm.
铆钉选择M12的圆形钢结构(铆钉直径优选为12mm)，受力方面与M12螺栓与接触轨底座的安装配套。横向相比扁钢减小了占用空间，尽量避免与轨道梁结构钢筋的冲突。The rivets are M12 round steel structures (the diameter of the rivets is preferably 12mm), and the force is matched with the installation of the M12 bolts and the base of the contact rail. Compared with the flat steel in the horizontal direction, the occupied space is reduced, and the conflict with the structural steel bars of the track beams is avoided as much as possible.
由于轨道梁采用混凝土结构，为提高该接触轨预埋槽道与轨道梁的连接强度，接触轨预埋槽道优选在轨道梁混凝土浇筑阶段即预埋在轨道梁中，与轨道梁形成整体，因此，为便于该接触轨预埋槽道的安装施工以及安装精度，在混凝土浇筑阶段，该接触轨预埋槽道往往需要通过轨道梁钢模板进行定位与施工。为便于具体的施工操作，可以在固定两根槽道的10mm直径的钢筋中间焊接一块L形的钢片，钢片一端和轨道梁模板内侧紧贴，钢片紧贴面设计一个小孔，用于铝锚钉与钢模板固定，后期拆卸模板时将铝锚钉拉断即可。Since the track beam adopts a concrete structure, in order to improve the connection strength between the busbar pre-buried channel and the track beam, the busbar pre-buried channel is preferably embedded in the track beam during the concrete pouring stage of the track beam, and forms a whole with the track beam. Therefore, in order to facilitate the installation and installation accuracy of the contact rail pre-buried channel, the contact rail pre-buried channel often needs to be positioned and constructed through the track beam steel formwork during the concrete pouring stage. In order to facilitate specific construction operations, an L-shaped steel sheet can be welded between the 10mm-diameter steel bars that fix the two channels. One end of the steel sheet is closely attached to the inner side of the track beam formwork, and a small hole is designed on the surface of the steel sheet. The aluminum anchors are fixed to the steel formwork, and the aluminum anchors can be broken when the formwork is disassembled later.
槽道长度优选为330mm，接触轨底座可以在槽道本体上灵活调整位置(如图3所示)，满足轨道梁上部空间的安装要求及接触轨固定要求。The length of the channel is preferably 330mm, and the position of the contact rail base can be flexibly adjusted on the channel body (as shown in Figure 3), which meets the installation requirements of the upper space of the track beam and the contact rail fixing requirements.
槽道材质采用Q235B钢，具有良好的强度和防腐性能，Q235B钢表面还可以采用3级热镀锌处理。The channel is made of Q235B steel, which has good strength and anti-corrosion performance. The surface of Q235B steel can also be treated with 3-grade hot-dip galvanizing.
具有以下优点：Has the following advantages:
1)槽道间距125mm，尤其适合接触轨底座孔间距125mm安装要求。1) The channel spacing is 125mm, which is especially suitable for the installation requirements of the contact rail base hole spacing of 125mm.
2)改变铆钉为M12圆钢形式，占用空间少，且安全可靠。2) Change the rivets to M12 round steel, which takes up less space and is safe and reliable.
3)采用一种铝锚钉与预制轨道梁的固定方式。3) A fixing method of aluminum anchors and prefabricated track beams is adopted.
4)槽道长度选择330mm，满足接触轨在竖向的移动调整量。4) The length of the channel is selected as 330mm to meet the vertical movement adjustment of the contact rail.
5)材料选择Q235B强度高，3级热镀锌耐腐蚀。5) The material selection is Q235B with high strength and grade 3 hot-dip galvanized for corrosion resistance.
城市轨道交通磁悬浮系统车辆是悬浮模式，采用轨道梁结构，轨道梁上面敷设F轨；车辆牵引动力电源采用敷设在轨道梁两侧的正负极接触轨供电；接触轨采用C型结构，授流方式为侧面授流。轨道梁一般采用预制预应力桥梁结构，不允许在轨道梁上采用打孔安装锚栓方式；而接触轨需固定在轨道梁两侧，本发明中的接触轨预埋槽道解决了不打孔安装接触轨的需求；该预埋槽道需满足接触轨安装，并适用于在轨道梁的预埋。The vehicle of the urban rail transit maglev system is in the suspension mode, adopting the track beam structure, and the F rail is laid on the track beam; the traction power supply of the vehicle is powered by the positive and negative contact rails laid on both sides of the track beam; The way is side flow. The track beam generally adopts prefabricated prestressed bridge structure, and it is not allowed to use the method of drilling and installing anchor bolts on the track beam; while the contact rail needs to be fixed on both sides of the track beam. The contact rail pre-buried channel in the present invention solves the problem of not drilling holes The requirements for installing contact rails; the embedded channel needs to meet the installation of contact rails and is suitable for pre-embedding in track beams.
