Description
技术领域technical field
本实用新型涉及涉及一种站台雨棚结构,特别涉及一种倾斜钢管混凝土树状柱站台雨棚结构。The utility model relates to a platform canopy structure, in particular to an inclined steel tube concrete tree column platform canopy structure.
背景技术Background technique
一般来说,雨棚在搭建的时候,以平顶的居多,尤其是对于钢结构或玻璃钢结构,往往也都使用这样的设计,这样的设计能达到很强的美观性,但其也表现出不足的方面,即其排水系统往往会受到影响。这种结构在遭受大暴雨或大雪的时候,积累的雨雪往往会产生巨大的荷载,增加梁、柱等构件的负担。此外,雨水对于下面支柱以及其他构件的腐蚀,会减少雨棚的使用寿命。为了解决排水问题,使站台雨棚的两排柱倾斜不同的角度,可使得雨棚自然产生一定的坡度,进而实现有组织排水。常见的站台雨棚,结构会受到列车进出站产生的风荷载、自重、地震产生的惯性力等荷载的作用,这些荷载最终都会传递到柱,使得柱底端弯矩较大,使得基础的造价增加。使用倾斜柱站台雨棚结构,柱身向外侧倾斜,自身重力可平衡掉一部分柱底端弯矩。由此设计时可减少柱控制截面的弯矩,降低柱身及基础的造价。此外,在地震作用下,相对于传统直立的柱子,两个方向倾斜的柱子可有效抵抗地震产生的水平惯性力Generally speaking, when the canopy is built, most of them are flat-roofed, especially for steel structures or fiberglass structures, such designs are often used. Such designs can achieve strong aesthetics, but they also show On the downside, its drainage system tends to suffer. When this structure suffers from heavy rain or snow, the accumulated rain and snow will often generate huge loads, which will increase the burden on beams, columns and other components. In addition, rainwater will corrode the pillars and other components below, which will reduce the service life of the awning. In order to solve the drainage problem, the two rows of columns of the platform canopy are inclined at different angles, which can make the canopy naturally produce a certain slope, and then realize organized drainage. The common platform canopy, the structure will be affected by the wind load generated by the train entering and leaving the station, the self-weight, the inertial force generated by the earthquake, etc. These loads will eventually be transmitted to the column, resulting in a large bending moment at the bottom of the column, making the cost of the foundation Increase. Using the inclined column platform canopy structure, the column body is inclined to the outside, and its own gravity can balance part of the bending moment at the bottom of the column. In this way, the bending moment of the column control section can be reduced during the design, and the cost of the column body and the foundation can be reduced. In addition, under the earthquake, compared with the traditional upright columns, the columns inclined in two directions can effectively resist the horizontal inertial force generated by the earthquake
近几十年来,钢管混凝土柱在土木工程特别是建筑结构领域得到越来越广泛地运用。钢管混凝土柱就是同时利用钢和混凝土的优点,使两种材料组合后的整体工作性能要明显优于二者性能的简单叠加,极大地提升其综合性能。作为站房柱,混凝土柱不如型钢美观,而纯钢结构又受到其稳定性的制约,因而规避两者缺点的钢管混凝土柱便应运而生。In recent decades, CFST columns have been used more and more widely in civil engineering, especially in the field of building structures. Concrete-filled steel tube columns use the advantages of steel and concrete at the same time, so that the overall performance of the combination of the two materials is significantly better than the simple superposition of the performance of the two, greatly improving its comprehensive performance. As a station building column, the concrete column is not as beautiful as the section steel, and the pure steel structure is restricted by its stability. Therefore, the steel pipe concrete column that avoids the shortcomings of the two came into being.
对于复杂的上部结构,一个束状柱头可提供多个支点,可分散原先一个节点的内力,使得支撑面扩大,减轻节点的负担。此外,在地震多发地区,节点区域往往破坏严重,钢结构节点便于工厂预制和灾后的修复工作,节点更换方便高效,不需要或仅需要少量的现场的湿作业。综合以上几方面的原因,倾斜钢管混凝土树状柱站台雨棚便应运而生。For complex superstructures, a beam-shaped column head can provide multiple fulcrums, which can disperse the internal force of the original node, expand the supporting surface, and reduce the burden on the node. In addition, in earthquake-prone areas, the joint area is often severely damaged. Steel structure joints are convenient for factory prefabrication and post-disaster repair work. The joint replacement is convenient and efficient, and no or only a small amount of on-site wet work is required. Combining the above reasons, the canopy of the inclined steel tube concrete tree column platform came into being.

具体实施方式detailed description
下面结合附图对本实用新型作进一步描述。以下实施例仅用于更加清楚地说明本实用新型的技术方案,而不能以此来限制本实用新型的保护范围。Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.
如图1、2和3所示,一种倾斜钢管混凝土树状柱站台雨棚,包括雨棚架,以及罩在雨棚架上方的挡雨板,其特征是,所述雨棚架包括立柱3、固定在立柱3上方的纵向桁架1和横向桁架2;所述纵向桁架1和横向桁架2首尾通过柱头4连接组成长方形框架,所述柱头4采用树状柱头,用于连接纵向桁架1、横向桁架2和立柱3,每个所述树状柱头连接一个立柱3、一个横向桁架2以及至少一个纵向桁架1,通过若干个树状柱头拼合成宽为纵向桁架,长为若干横向桁架的雨棚架;所述横向桁架2两侧的立柱均朝横向桁架2的中心方向倾斜,其中一侧立柱的倾斜角大于另一侧的倾斜角。As shown in Figures 1, 2 and 3, an inclined steel tube concrete tree column platform canopy includes a canopy frame and a rain shield covering the top of the canopy frame, and the feature is that the canopy frame includes a column 3. The longitudinal truss 1 and the transverse truss 2 fixed on the top of the column 3; the longitudinal truss 1 and the transverse truss 2 are connected from head to tail through the column head 4 to form a rectangular frame, and the column head 4 adopts a tree-like column head for connecting the longitudinal truss 1, Horizontal trusses 2 and columns 3, each of the tree-shaped column heads connects a column 3, a horizontal truss 2 and at least one longitudinal truss 1, and a plurality of tree-shaped column heads are combined to form a longitudinal truss in width and a length of several horizontal trusses Scaffolding: the uprights on both sides of the transverse truss 2 are all inclined towards the center of the transverse truss 2, and the inclination angle of the uprights on one side is greater than that on the other side.
本实施例中,所述立柱3均采用完全相同的钢管混凝土结构。In this embodiment, the columns 3 all adopt the same steel tube concrete structure.
本实施例中,所述柱头4与纵向桁架1、横向桁架2以及立柱3通过焊接连接。In this embodiment, the column head 4 is connected with the longitudinal truss 1 , the transverse truss 2 and the column 3 by welding.
本实施例中,所述倾斜角为立柱3与铅垂线的夹角,一侧的夹角为20度,另一侧的夹角为15度。In this embodiment, the inclination angle is the angle between the column 3 and the vertical line, the angle on one side is 20 degrees, and the angle on the other side is 15 degrees.
本实施例中,所述树状柱头分为下弦分支和上弦分支,所述下弦分支包括下弦锚5和与下弦锚一体成型的向外扩散的若干下弦树枝6,所述上弦分支包括上弦锚7和与上弦锚一体成型的向外扩散的若干上弦树枝8,其中下弦锚5浇筑在混凝土中,与立柱一起预制,上弦锚7和其中一个下弦树枝6焊接连接,所述上弦树枝8通过焊接连接横向桁架2或者纵向桁架1,树状柱头大大减轻节点的负担而且增加了美观效果。具体的:下弦锚的作用在将横向或纵向桁架的剪力传递给立柱,转换为立柱所承受的轴力和弯矩。下弦锚浇筑在混凝土中,保证柱头与立柱的连接,不至立柱与柱体脱落。下弦锚的一个树枝用于与上弦锚焊接,而其他树枝的作用在于与其相邻的横向或纵向的下弦杆相连。与桁架连接是同侧的上弦树枝和下弦树枝分别连接桁架的上下端。能够减轻节点的负担的原理:对于一般的梁柱节点(或者是桁架的节点),横梁传来的剪力将在节点部位产生巨大的应力,因而在地震等灾害发生时,节点往往先产生破坏。而此种柱头节点,将横向或纵向桁架的上弦、下弦传来的剪力分别传递给立柱,而非一次性直接传递,因而可以达到减少柱头节点负担的效果。In this embodiment, the tree-like stigma is divided into a lower chord branch and an upper chord branch, the lower chord branch includes a lower chord anchor 5 and a plurality of lower chord branches 6 integrally formed with the lower chord anchor and spreads outward, and the upper chord branch includes an upper chord anchor 7 and a number of upper string branches 8 that are integrally formed with the upper string anchors and spread outward, wherein the lower string anchors 5 are poured in concrete and prefabricated together with the columns, and the upper string anchors 7 are welded to one of the lower string branches 6, and the upper string branches 8 are connected by welding Horizontal truss 2 or vertical truss 1, the tree-like column head greatly reduces the burden on nodes and increases the aesthetic effect. Specifically: the function of the lower chord anchor is to transmit the shear force of the horizontal or longitudinal truss to the column, and convert it into the axial force and bending moment borne by the column. The lower chord anchor is poured in concrete to ensure the connection between the column head and the column, so that the column and the column body will not fall off. One branch of the lower chord anchor is used for welding with the upper chord anchor, while the other branches are used to connect with its adjacent transverse or longitudinal lower chord. The connection with the truss is that the upper and lower chord branches on the same side are respectively connected to the upper and lower ends of the truss. The principle of reducing the burden on nodes: For general beam-column nodes (or truss nodes), the shear force transmitted by the beam will generate huge stress at the node, so when disasters such as earthquakes occur, the nodes are often damaged first . This kind of column head node transmits the shear force transmitted from the upper and lower chords of the horizontal or longitudinal truss to the column respectively, instead of directly transmitting it at one time, so the effect of reducing the burden on the column head node can be achieved.
搭建过程:Build process:
1、事先做好立柱的基础,基础可采用柱下独立基础的形式,基础材料可选用钢筋混凝土或纯钢结构形式。因立柱外包钢管,故立柱可较方便得与钢材连接。立柱吊装施工完毕后,用细石混凝土做填缝处理;1. Prepare the foundation of the column in advance. The foundation can be in the form of an independent foundation under the column, and the foundation material can be reinforced concrete or pure steel structure. Because the uprights are covered with steel pipes, the uprights can be connected with steel more conveniently. After the column hoisting construction is completed, the fine stone concrete is used for caulking;
2、待填缝混凝土具备一定强度以及立柱沉降均匀后,将柱头的下弦杆分支焊接至两个纵向桁架的下弦杆以及所相邻的横向下弦杆上,形成矩形的框架,待变形稳定后再焊接柱头的上弦杆分支,并将上弦杆分支以此与对应的桁架上弦杆相连;2. After the joint-filling concrete has a certain strength and the settlement of the column is uniform, the lower chord branch of the column head is welded to the lower chord of the two longitudinal trusses and the adjacent horizontal lower chord to form a rectangular frame. Weld the upper chord branch of the column head, and connect the upper chord branch with the corresponding truss upper chord;
3、依照上述步骤,以此施工,直至所有的杆件安装完毕。3. Follow the above steps to carry out construction until all the rods are installed.
