Description

Technical Field

[0001] The present invention belongs to the technical field of structural engineering, and in particular relates to a modular building system of circular steel tube corrugated plate concrete special-shaped columns and H-shaped steel composite beams. Background Art

[0002] At present, new urbanization construction is underway in my country, and many places are undergoing demolition and reconstruction. However, traditional building structure types have high energy consumption during the construction phase, serious environmental pollution, difficult recycling of building resources and long construction periods. There are many contradictions between the development of the construction industry and people's demand for industry development. In response to the country's 2030 "carbon peak" policy, prefabricated buildings have become the future direction of the construction industry.

[0003] Compared with traditional prefabricated buildings, modular buildings are prefabricated buildings with a higher degree of industrialization. They have made significant improvements in technological innovation and standardization of architectural design, mechanized production, equipment supply and matching, construction and installation, etc., with a high industrialization ratio, and have the advantages of fast construction speed, low project cost, reusable components, and low construction noise. They meet my country's requirements for the development of green buildings. In the context of building industrialization, as the advantages of modular structures gradually become more prominent, they are being recognized and popularized by society and are developing rapidly. The design of early modular buildings was relatively simple, and modular design at the level of building decoration engineering was not considered, and the interior decoration was relatively rough. The protruding columns and pipelines of traditional rectangular cross-sections not only affect the appearance but also occupy the usable space of the building. Most of their application scenarios are temporary construction sites, etc. However, with the transformation and upgrading of building industrialization and the development of multi-story buildings, higher demands are put forward for modular building structure design that can be used for multi-story and permanent buildings. Due to the influence of module unit size, the cross-section of the main load-bearing components of traditional modular buildings is small, and there are problems with stress and stability. Strict structural design and calculation are usually required to improve the stability of the structure, or additional core tubes and support frames are required. It is difficult to meet the stress requirements of its development into multi-story buildings, so it needs to be improved. Summary of the Invention

During on-site installation, it is only necessary to connect the relevant connections between modules and carry out the decoration construction of the connection parts.

[0076] Box-type standard modules A to C are prefabricated in the factory, which increases the speed of on-site construction.

[0077] Among them, the box-type standard modules A to C can be assembled in the factory prefabrication stage, and the processing of each component is completed first during processing.

[0078] The factory-prefabricated steel parts of the box-type standard modules only require welding to be connected.

[0079] The water supply 61 , air conditioning 62 , and power supply 63 in the box-type standard modules A to C can pass through the openings of the H-shaped steel honeycomb composite beams 161 and 171 inside the H-shaped steel honeycomb composite beams 16 and 17 .

[0080] The shape of the honeycomb holes of the H-shaped steel honeycomb composite beams 16 and 17 can be at least one of circular, rectangular, hexagonal, etc., or a combination thereof, and can also be a solid web section.

[0082] By pouring concrete in the circular steel tube frame column 114 and the end pull-out members in the node connection module to form a reliable anchor, high-strength concrete such as steel slag concrete, steel fiber concrete, and carbon fiber concrete can be chosen to be discarded or replaced according to design requirements.

[0083] Among them, the new circular steel tube corrugated plate concrete special-shaped column modules 11 to 41 are poured with lightweight aggregate concrete during component processing, and can be discarded or replaced with ceramsite concrete, steel slag concrete, steel fiber concrete, carbon fiber concrete and other concrete according to design requirements.

[0085] Among them, the H-shaped steel connecting plate is divided into an inner plate 215 and an outer plate 216. The outer plate 216 has a small hole that only needs to be able to accommodate the end anti-pullout parts 51 of the node connection modules E, F, and G; the inner plate 215 has a circular hole with the same outer diameter as the round steel tube frame column 114, and the round steel tube frame column 114 is inserted into the circular hole of the inner plate 215 and welded to the outer surface.

[0086] The H-shaped steel connecting plate is divided into an inner plate 215 and an outer plate 216 and is welded to the H-shaped steel honeycomb beams 161 and 171 of the H-shaped steel honeycomb composite beams 16 and 17 by groove welding during prefabrication in the factory.

[0087] Among them, connector 1 E, connector 2 F and connector 3 G in the node connector modules E, F and G adopt a split design. Connector 1 E, connector 2 F and connector 3 G can adopt an integrated design according to the stiffness requirements of the building design, that is, the perforated steel plates in the node connector modules E, F and G are replaced with "T"-shaped, "L"-shaped and "X"-shaped integral steel plates.

[0088] When constructing the cast-in-place foundation, the node connection modules E, F, and G need to be embedded in advance.

[0089] Among them, the concrete of the second upper prefabricated plate 12.5, the second lower prefabricated plate 13.5, and the outer peripheral frames 121.5 and 131.5 of the tooth-shaped coupled prefabricated layered floor slabs 12 and 13 is extended and filled into the outer peripheral contours of the H-shaped steel honeycomb beams 161 and 171, and forms H-shaped steel honeycomb composite beams 16 and 17 with the H-shaped steel honeycomb beams 161 and 171. The mutual combination of the floor slabs and the H-shaped steel honeycomb composite beams 16 and 17 greatly improves the bending resistance of the two, reduces the beam height, and improves the building's usable clearance.

[0090] The second upper precast panel 12.5 and the second lower precast panel 13.5 may be cast in concrete of one or more kinds of ordinary concrete and lightweight aggregate concrete, and the backfill layer of the floor heating pipe 135 may be made of one of lightweight backfill materials such as pebble concrete, cement mortar, ceramsite concrete, and foamed cement.
