Description
技术领域technical field
本发明属于建筑机械技术领域，特别是涉及一种带剪力架的内爬塔式起重机支护结构。The invention belongs to the technical field of construction machinery, in particular to an inner climbing tower crane support structure with a shear frame.
背景技术Background technique
用于高层和超高层建筑的塔式起重机通常采用外挂或内爬式两种方式支撑在建筑物上，并随着建筑物的升高而升高，外挂或内爬是根据建筑物施工的需要而确定的。Tower cranes used in high-rise and ultra-high-rise buildings are usually supported on the building in two ways: external hanging or internal climbing, and rise as the building rises. External hanging or internal climbing is based on the needs of building construction. And sure.
目前所用的带剪力架的内爬塔式起重机支护结构基本上有两种结构形式。一种是由两根爬升主梁、支座、支腿等部分组成的支护结构，主梁两端与墙体连接。内爬式塔机安装在电梯井道内，由于安装构造要求，必须在电梯井剪力墙上埋上预埋件，两个主梁的四个支座与事先埋好的预埋件支座通过螺栓连接，这种内爬支撑结构比较简单。但由于塔机支座置于主梁上表面，塔机传递到主梁的水平力在主梁上产生扭矩，并传递到两端的支座上，不利于主梁和两端支座的受力状态。也有的在两根主梁之间加装水平连接杆，但由于对主梁的扭转没有抑制作用，并不能改善主梁的受力状态，由于主梁支座上都有塔机支撑框架，所以水平连接杆对改善梁体的受力状态没有实际意义。At present, there are basically two structural forms of the internal climbing tower crane support structure with shear frame. One is a support structure composed of two climbing main beams, supports, outriggers and other parts, and the two ends of the main beam are connected with the wall. The internal climbing tower crane is installed in the elevator shaft. Due to the requirements of the installation structure, embedded parts must be embedded on the shear wall of the elevator shaft. The four supports of the two main girders pass through the pre-buried embedded parts Bolt connection, this internal climbing support structure is relatively simple. However, since the tower crane support is placed on the upper surface of the main girder, the horizontal force transmitted from the tower crane to the main girder generates a torque on the main girder and is transmitted to the supports at both ends, which is not conducive to the stress on the main girder and the supports at both ends state. There are also horizontal connecting rods installed between the two main girders, but because there is no restraint on the torsion of the main girder, the stress state of the main girder cannot be improved. Since the main girder supports have tower crane support frames, so The horizontal connecting rod has no practical significance to improve the stress state of the beam body.
另一种内爬支护结构在第一种内爬结构的基础上在主梁的一侧安装水平斜撑杆，一般为三根水平斜撑杆，杆的另一端与墙体相连，两个主梁的四个端部分别与左右两面墙体相连，两个主梁之间通过塔机支撑框架连接，这种内爬结构通过水平斜撑杆将塔机产生的水平力直接传递到墙体上，能够改善主梁梁体和主梁两端墙体的受力状态。但需要增加支撑水平斜撑杆的与墙体连接处的预埋件，安装过程也比较复杂，并增加了塔机的支护成本。Another internal climbing support structure is based on the first type of internal climbing structure. Horizontal diagonal bracing rods are installed on one side of the main beam, generally three horizontal diagonal bracing rods. The other end of the rods is connected to the wall. The four ends of the beam are respectively connected to the left and right walls, and the two main beams are connected by the supporting frame of the tower crane. This internal climbing structure directly transmits the horizontal force generated by the tower crane to the wall through horizontal diagonal braces. , which can improve the stress state of the main girder body and the walls at both ends of the main girder. However, it is necessary to increase the embedded parts at the connection between the horizontal diagonal brace and the wall, the installation process is also relatively complicated, and the support cost of the tower crane is increased.
本发明所述的内爬式塔式起重机支护结构，包括两个主梁、两个主梁间的剪力架、支座及连接件，所述剪力架为两个，在两个主梁间平行设置，沿两主梁法向中心线对称，每个主梁两端分别安装有与墙体预埋件连接的连接件。内爬支护结构主梁受到塔机水平力作用时将产生扭矩，并发生扭转变形，剪力架斜支杆具有保持剪力架形状不变的作用，与剪力架连接后两主梁各自的扭转变形受到约束，从而将主梁各自的扭矩转变到梁端支座上的垂直载荷，改善了主梁的受力状态，主梁端部连接处的受力状态，同时也改善了支撑主梁墙体的受力状态，并且这种支护结构安装过程简单，容易操作，能够降低支护成本。The support structure of the inner climbing tower crane according to the present invention comprises two main girders, a shear frame between the two main girders, a support and a connector. The beams are arranged in parallel and symmetrical along the normal center line of the two main beams, and the two ends of each main beam are respectively installed with connecting pieces connected with the embedded parts of the wall. When the main girder of the internal climbing support structure is subjected to the horizontal force of the tower crane, it will generate torque and undergo torsional deformation. The oblique struts of the shear frame can keep the shape of the shear frame unchanged. The torsional deformation of the main girder is constrained, so that the respective torques of the main girder are transformed into the vertical load on the beam end support, which improves the stress state of the girder, the stress state of the connection at the end of the girder, and also improves the support of the main girder. The stress state of the beam wall, and the installation process of this support structure is simple, easy to operate, and can reduce support costs.
