Description

一种柔性悬挂式模块建筑结构Flexible hanging module building structure 技术领域Technical field
本发明属于土建技术领域,具体是一种柔性悬挂式模块建筑结构。The invention belongs to the technical field of civil engineering, in particular to a flexible suspended module building structure.
背景技术Background technique
模块建筑是一种预制装配式三维盒子单元,一个单元里一般是1-3个房间,模块单元一般采用钢结构制造,模块制作及设备安装占总建造工程量的90%,均在工厂流水线上完成,机械化和工业化程度高,并降低污染排放。制造厂家把外墙、装修、家具、设备等全部整合到这个盒子单元(模块)中,运往现场进行吊装拼接,不仅结构部分施工便捷,还免去了后期的装修等工作。The module building is a prefabricated three-dimensional box unit. One unit is usually 1-3 rooms. The module unit is generally made of steel structure. The module production and equipment installation account for 90% of the total construction work, all on the factory assembly line. Completed, mechanized and industrialized, and reduced pollution emissions. The manufacturer integrates the exterior wall, decoration, furniture, equipment, etc. into the box unit (module), and transports it to the site for hoisting and splicing. Not only the structural part is convenient to construct, but also the post-renovation work is eliminated.
相对于其他预制装配结构,模块建筑的优点主要有以下几方面:由于高度整合,免去了后续的装修、设备管线安装等工序,进一步缩短建造时间、节省现场人力;每个模块自成结构体系,无论是运输、吊装还是就位,都无须额外的支撑件,可以采用较为便捷的堆放式就位;工厂的流水线式装修、安装设备的方式,进一步提高室内品质,更符合商品住宅的市场要求。Compared with other prefabricated assembly structures, the advantages of modular building mainly include the following aspects: due to the high integration, the subsequent decoration, equipment pipeline installation and other processes are eliminated, further shortening the construction time and saving the manpower on site; each module has its own structural system. Whether it is transportation, hoisting or in place, no additional support is needed, and it can be conveniently placed in place; the factory's assembly line decoration and installation equipment can further improve the indoor quality and meet the market requirements of commercial housing. .
基于以上几方面的优点,模块建筑适用于但不限于以下场合:工期紧迫的工程,例如需要按期住进新生的学校宿舍;人手奇缺的工程,例如边远地区的成规模建设;气候恶劣的工程,例如冬季施工;对装修品质有特殊要求的工程,例如是星级酒店等。Based on the advantages of the above aspects, the modular building is applicable to, but not limited to, the following occasions: projects with tight schedules, such as the need to live in new school quarters on schedule; projects that are lacking in manpower, such as scale construction in remote areas; For example, winter construction; works with special requirements for decoration quality, such as star-rated hotels.
然而,模块内部的构件限于空间要求、连接方便的要求及自重限制,构件尺寸有限,无法达到很高的水平向承载力,因而在目前实际工程应用中,多高层模块建筑需要外加抗水平力结构,以帮助模块建筑承载,可以是混凝土核心筒或其它形式。模块把所受到的水平向荷载通过有效连接传递给核心筒,模块本身仅承受竖向荷载以及极小量的水平荷载。因此,在高层的模块建筑案例中,模块+混凝土核心筒的结构形式被普遍采用,抗水平地震力体系仅有核心筒一道防线,是较为不合理的结构形式。模块给核心筒传递过大的水平荷载,往往造成很大的材料用量。另一方面,在高层的模块建筑案例中,模块的自重直接向下传递,底部的模块承受过大的竖向荷载,增加了模块内部构件尺寸,进而又增加结构自重,影响使用功能。However, the components inside the module are limited by space requirements, convenient connection requirements and self-weight restrictions. The components are limited in size and cannot achieve high horizontal bearing capacity. Therefore, in current practical engineering applications, multi-high-rise module buildings need to be added with horizontal force resistance structure. To help the module building load, it can be a concrete core tube or other form. The module transmits the horizontal load received to the core barrel through an effective connection, and the module itself is only subjected to vertical loads and a very small amount of horizontal load. Therefore, in the case of high-rise modular construction, the structural form of the module + concrete core tube is generally adopted, and the horizontal seismic force system only has a core tube and a line of defense, which is a relatively unreasonable structural form. The module delivers excessive horizontal loads to the core barrel, often resulting in large material usage. On the other hand, in the high-rise module construction case, the self-weight of the module is directly transmitted downward, and the module at the bottom is subjected to excessive vertical load, which increases the size of the internal components of the module, thereby increasing the structural weight and affecting the use function.

Each damper 5 plays a role when the module 3 and the core tube structure 1 move relative to each other. The damper 5 also has a certain elastic stiffness to provide the horizontal stiffness of the module 3 structure. A limit buffer device 7 is disposed between the vertically adjacent modules 3, and the limit buffer device 7 is used to prevent the vertical adjacent module 3 from colliding vertically when the horizontal relative displacement is large. Specifically, as shown in FIG. 3, the limit buffer device 7 comprises two interconnected rods 8, the free ends of which are respectively connected to the vertically adjacent modules 3, one of which is connected to the bottom corner of the upper module 3 and the other of which is connected The lower corner of the lower module 3 and the upper module 3 are vertically adjacent.

This type A rod set acts as a lever to reduce the elongation of the wire rope proportionally and avoid premature breakage. The floor of each module 3 is connected to the core tube structure 1 through a damper 5, and the damper 5 plays a major energy-consuming role when the module 3 and the core tube structure 1 move relative to each other. The damper 5 has a certain elastic rigidity to provide The horizontal stiffness of the module 3 structure. Further, when only the wind load acts, since the damper 5 acts as a sliding load, the damper 5 does not slip, and the wind load can be directly transmitted to the core barrel structure 1. As shown in FIG. 4, the ceiling beam 10 of the module is provided with an extension section outside the beam-column node, and the ceiling beam is provided with a stiffener 12 at a corresponding position.

The epitaxial section of the ceiling beam of the module acts to allow the suspension rod 4 to oscillate within a certain range without causing a collision. A diagonal support member 6 is also provided in each module 3, and the diagonal support member 6 reinforces the structure of the module from the inside. As shown in FIG. 5, a slidable prefabricated floor slab 15 is disposed between each module 3 and the core tube structure 1 so that the two can move relative to each other while maintaining relative movement. The channel steel 20 is pre-embedded in the prefabricated floor panel 15. Before the pre-buried channel steel 20 and the connecting steel plate 19 have been connected by high-strength bolts 18, the steel plate 19 is connected with the beam-column joints at the module floor for on-site welding, and the other end of the prefabricated floor panel 15 is placed. On the groove of the core tube floor panel 17, both sides of the resting contact surface are provided with a pre-embedded contact steel plate 21, which can form a frictional sliding. A pre-buried anti-collision steel plate 22 is disposed on the vertical end surface of the groove, and the above embedded parts each have a pre-embedded anchor rib 23 welded thereto. A module interlayer damper 16 is further disposed between the vertically adjacent modules 3, and the two ends of the module interlayer damper 16 are respectively connected to the floor beam column node of the upper module 3 and the ceiling beam 5 column node of the lower module 3.
