Description

Modular building and construction method thereof

Technical field

The invention relates to a modular building and a construction method thereof, belonging to the technical field of construction.

Background technique

A modular building is generally formed by stacking multiple modular building units similar to containers. The material, structure and thickness of each modular building unit are the same. When multiple modular building units are stacked in the vertical direction At this time, the module building unit at the lowest level will bear the weight of all module building units above it, which will inevitably affect the overall structural stability of the building. Therefore, the height (number of floors) of this type of stacking modular building will be strictly limited. Under normal circumstances, it is not suitable for buildings with more than 6 floors. If you want to make a breakthrough in building height, you must design the modular building units on different floors in a personalized way. For example, design the structural strength of the lower module building unit to be higher than that of the upper module building unit; Even so, the shear resistance of high-rise modular buildings has also been challenged.

The application of existing steel structure buildings in high-rise and super high-rise buildings is becoming more and more mature, and it has gradually become the mainstream construction technology, which is the development direction of future buildings. The main structure of steel structure buildings has the characteristics of high construction efficiency, but the main structure is completed The construction volume of back wall panels and floor slabs is huge, and the construction efficiency is not as good as prefabricated buildings and modular buildings.

Summary of the invention

In order to overcome the problems in the prior art, the present invention provides a modular building and a construction method thereof, so as to improve the construction efficiency of middle and high-rise buildings and reduce the amount of construction on the construction site. The specific technical solutions are as follows.

A modular building is characterized in that it comprises a main structure and a building module unit, the main structure has a plurality of accommodation spaces; the building module unit is accommodated in the accommodation space of the main structure, and the building module unit It is fixedly connected with the main structure.

Further, the building module unit is a prefabricated component, which at least includes a bottom surface, a left side surface, a top surface and a right side surface connected in sequence. Preferably, the building module unit is prefabricated by integral casting.

Further, a plurality of the building module units are contained in the accommodating space, and the building module units are arranged in the accommodating space along a depth direction and/or a height direction.

Further, the accommodation space is distributed along the horizontal direction and/or the height direction of the main structure.

Preferably, the main structure is a frame structure, a frame tube structure or a frame shear structure.

Preferably, the main structure adopts a steel structure, which includes uprights and beams, the containing space is surrounded by a plurality of uprights and a plurality of beams, and the containing space is located between two adjacent layers of beams.

Preferably, the building module unit is provided with openings for installing doors and/or windows; pipelines are embedded in the building module units, and the pipelines can form water, electricity, and gas circuits. The edges and/or corners of the building module unit are embedded with a connecting structure for connecting with the main structure, and the connecting structure may be a connecting box, a embedded sleeve, a fastener, or a welding piece.

Based on the same inventive concept, the present invention also relates to the construction method of the above-mentioned modular building, which mainly includes the following steps:

1) Construction of the building foundation. After the completion of the building foundation construction, the main structure shall be constructed layer by layer;

2). After the construction of the first layer of beams of the main structure is completed, hoist the building module unit to the top of the layer of beams;

3). Fixedly connect the building module unit to the main structure;

4). Repeat steps 3) and 4) until the top layer of the building is completed.

Compared with the prior art, the biggest feature is to separate the load-bearing component (main structure) of the building and the functional separation component (building modular unit) of the building. In the existing building system, the main structure (such as the frame-shear structure) not only plays the role of load-bearing, but also plays the role of functional zoning. Floors and wall panels are either constructed after the main structure or at the same time as the main structure. , Construction efficiency is low. For modular buildings, limited by the structural strength of a single module, modular buildings are only suitable for low-rise buildings. The main structure of the modular building of the present application mainly plays the role of bearing and shear resistance, and can be used in middle and high-rise buildings; the modular building units mainly play the role of using functional partitions. The construction method of the present invention is simple, and the construction efficiency is greatly improved compared with the existing middle and high-rise buildings. The prefabricated production of the building module unit is completed in the factory in advance, transported to the construction site, hoisted and fixed, and the workload on the construction site is greatly reduced . The modular building of the present invention can be applied to buildings with 10-40 floors and has excellent efficiency advantages.
