Description
技术领域 technical field
本实用新型涉及建筑结构技术领域，具体涉及一种钢结构梁柱节点。 The utility model relates to the technical field of building structures, in particular to a beam-column node of a steel structure.
背景技术 Background technique
近年来，钢结构的应用越来越广泛。与其他结构形式相比，建筑钢结构具有卓越的抗震性能，在历次地震中震害较少，经受得住考验，很少发生整体破坏和倒塌现象。但是同时也发现在地震中，钢结构经常会发生局部破坏：框架节点区的梁柱焊接连接脆性破坏；竖向支撑的整体和局部破坏；柱脚的柱翼缘和柱子底板的破裂等。其中钢柱与钢梁节点处发生破坏的几率最大，约占所有局部破坏的七成以上。主要因为在强震作用下，节点处受力较集中，极易发生变形。 In recent years, the application of steel structures has become more and more extensive. Compared with other structural forms, architectural steel structures have excellent seismic performance, have less earthquake damage in previous earthquakes, can stand the test, and seldom have overall damage and collapse. But at the same time, it is also found that in earthquakes, local damage often occurs in steel structures: brittle failure of beam-column welded connections in the frame joint area; overall and local damage of vertical supports; cracking of column flanges at column feet and column bottom plates, etc. Among them, the joints of steel columns and steel beams have the highest probability of failure, accounting for more than 70% of all local failures. The main reason is that under the action of strong earthquakes, the stress on the nodes is relatively concentrated, and deformation is very easy to occur.

具体实施方式 Detailed ways
下面结合附图和实施例对本实用新型做进一步说明：一种钢结构梁柱节点，包括钢柱1以及与钢柱1连接的钢梁。所述钢柱1为方形钢管，所述钢梁为H型钢，包括腹板2a和翼缘2b，所述翼缘2b焊接在钢柱1上，此连接方式可以更好的传力，有利于提高节点的抗弯能力。所述腹板2a两侧设有与钢柱1和钢梁连接的等边角钢3。所述钢柱1的四个侧面分别开有八个螺栓孔，腹板2a两侧各有四个，本实用新型中钢柱1的四个侧面上均设有钢梁，实际应用中，用户可以根据需要设定四个或小于四个的钢梁。所述钢梁的腹板2a上开有四个螺栓孔，所述等边角钢3的两个面上各开有四个螺栓孔。所述钢梁通过腹板2a上的螺栓孔、等边角钢3底面的螺栓孔以及高强度螺栓与等边角钢3连接，所述钢柱1通过侧面上的螺栓孔、等边角钢3竖面上的螺栓孔以及高强度螺栓与等边角钢3连接。等边角钢3的设置以及与钢柱1和钢梁之间所采用的高强度螺栓连接方式，改善了钢结构梁柱节点的延性，有利于增强节点的抗震能力。所述钢梁在梁端翼缘2b两侧分别设有钢侧板4，所述钢侧板4焊接在钢柱和钢梁的梁端翼缘两侧，钢侧板4的宽度为50mm~100mm，长度为400mm~900mm。因为翼缘2b在钢侧板4远端位置处宽度突然变窄，所以当地震发生时，变形更容易发生在宽度突然变窄的部位，解决了现有技术中变形集中出现在节点处的问题，进一步提高了钢结构整体的抗震性能。 The utility model will be further described below in conjunction with the accompanying drawings and embodiments: a beam-column node of a steel structure, comprising a steel column 1 and a steel beam connected to the steel column 1 . The steel column 1 is a square steel pipe, and the steel beam is an H-shaped steel, including a web 2a and a flange 2b, and the flange 2b is welded on the steel column 1. This connection method can transmit force better, which is beneficial to Improve the bending resistance of nodes. The two sides of the web 2a are provided with equilateral angle steel 3 connected with the steel column 1 and the steel beam. The four sides of the steel column 1 are respectively provided with eight bolt holes, and there are four on both sides of the web 2a. Steel beams are arranged on the four sides of the steel column 1 in the utility model. In practical applications, users Four or less steel beams can be set as required. Four bolt holes are opened on the web plate 2a of the steel beam, and four bolt holes are opened on the two surfaces of the equilateral angle steel 3 respectively.
