Description

Modularity beam-to-column connection device and attaching method thereof
Technical field
The present invention relates to building engineering equipment technical field, be related in a kind of steel structure modularization building steel structure module it Between connecting joint structure, particularly a kind of modularity beam-to-column connection device and attaching method thereof.
Background technology
With fast development social in the last few years, the improvement of people's living standards, architectural mode are also quietly occurring Change, people to build requirement no longer only focus on house overall structure performance, and the quality for construction and Speed there has also been higher requirement.
Assembled architecture is utilized in the construction style is assembled by plant-manufactured component conveying to job site. The advantage of this building includes that construction speed is fast, climate conditionality is little, saves labour force and can improve construction quality. The development of assembled architecture is the key link of building industrialization, and the final realization means of industrialized building and basic feature.
At present, according to different prefabricated degree, assembled architecture is generally can be divided into using prefabricated unit:Bar element, Plate body unit and modular unit are several, and architectural structure system corresponding to which is:Direct fabricated construction system, precoated plate body unit Structural system and modular architectural structural system.
Modular architectural has the prefabricated ratio of height as a kind of emerging building system, to improve construction quality, Reduction of erection time, use manpower and material resources sparingly, the many-side such as environmental protection has significant advantage, meet for building industrialization and green The demand for development of building.
Modular architectural structural system generally carried out in factory using whole room as single space module unit it is prefabricated, and The inner space of modular unit can be arranged and finishing, transport afterwards makes module reliably connect to construction site using lifting It is connected in building overall.
Steel structure modularization building is referred to transports to building site by attachment structure by the good steel structure module of prefabrication Couple together composition building overall.Steel structure module is the elementary cell of steel structure modularization building, and which combines and connected mode Directly it is closely related with the image and mechanical property of building.Steel structure modularization building is at the early-stage in China, to its steel construction The research of modular connection is seldom and industrialization degree is not high, still exists many in the design of steel structure module attachment means Problem, this is unfavorable for the development of Chinese modular architectural.
Existing steel structure module is built mainly by 3 types.The first kind be with Container Reconstruction into container house:Can Discarded cargo containers are reused, also new container can be transformed so as to possess the building function of needs, advantage is It is sturdy and durable, have the disadvantage that steel using amount is larger and module size is relatively simple;Equations of The Second Kind is the mould constituted using light gauge cold-formed steel shape Block system:Steel using amount is saved, and size is more flexible, and intermodule connection is more convenient, has the disadvantage that bearing capacity is not high, is simply possible to use in low, multilamellar Building;3rd class is the building module being welded using shaped steel, with bearing capacity it is higher, size Selection is more flexible the characteristics of.
And for the building module being welded using shaped steel, its attachment means connects its connected mode, building is directly affected Aesthetic measure and carry situation, therefore, attachment means connect its connected mode for steel structure modularization building for close weight Will.
103993654 A modular assembly formula structure of steel structure building systems of Chinese patent CN, disclose modular assembly Formula structure of steel structure building system, including assembled inner room module and connection member;Wherein, assembled inner room module is applied in factory Work is prefabricated to be completed;The assembled inner room module includes beam, post, floor and the structure added by project demand wherein and sets It is standby;At the construction field (site), can be attached by connector between inner room unit;Connection member includes high-strength bolt, in module At connection hole and exterior wall junction install fill up part and decorative element or the cast-in-place of installation operation hole fills up portion Part, intermodule play the heating pad pipe that the water supply and sewerage pipeline and water supply and sewerage pipeline connection member, intermodule of interconnection function plays interconnection function Road and hot duct connection member, intermodule rise the electric wire and wired portion part and assembled transporting equipment of interconnection function or Stair.Connection member in this patent is mainly high-strength bolt, and this kind of processing mode junction is more, constructs extremely complex, and Firmness can not be ensured.
104763059 A of Chinese patent CN connectors for building, frame structure and the side with connector assembling frame structure Method, discloses a kind of section combination modular architectural connector, outside including a central module and several therefrom center portion parts The connecting portion of extension;The fixing device for tie-beam column material is provided with connecting portion, and wherein, fixing device is screw.This Coupling assembly framework for building is identical with interconnection technique used in aforementioned patent, is the cooperation using screw with bolt.But It is that the workload of this kind of form of construction work greatly, needs each screw to be fixedly connected, and the increase of link position, undoubtedly The risk of loosening can be increased, the bearing capacity of building is reduced.
The content of the invention
