Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present application clearer, embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in various embodiments of the present application in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.

With the rapid development of economy, the construction period becomes a key factor affecting the construction cost. The modular building divides the building into a plurality of space modules, each space module is distributed with box-type structure units, and the box-type structure units are spliced and combined after being transported to the site. The building form can shorten the building period to a great extent, thereby meeting the requirement of short construction period.

The box-type structural unit of the modular building is divided into a skeleton-free system and a skeleton system. The box-type structural unit adopting a framework-free system is generally formed by pouring concrete, the box-type structural unit adopting the framework system generally adopts steel and reinforced concrete as frameworks, and a box body is formed by enclosing light plates. Compared with a box-type structure unit adopting a skeleton-free system, the box-type structure unit adopting the skeleton system has lighter self weight and larger internal space.

In a box-type structure unit adopting a framework system, a beam body is connected with a column body to form an integral frame of a box body. Regarding the size of the integral frame of the box body, the height limit requirements of bridges, tunnels and the like in the transportation process of the box type structure unit and the selection of a crane for field hoisting can be properly selected.

At present, the modular building formed by splicing and combining box-type structural units has high requirement on large internal space in order to obtain wide space. However, in a box-type structural unit having a large internal space, the span of the beam is also large, and the beam is easily deformed when the span is large. In order to improve the stress of the beam body and prevent the beam body from deforming and even breaking, a column is additionally arranged at a part of the beam body to increase the support so as to improve the stress of the beam body.

However, if the support is added to the beam, for example, the center pillar is provided to support the beam, so that the box-type structure units occupy the internal space of the modular building when the modular building is formed by splicing and combining the box-type structure units. When equipment needs to be operated in the interior of the modular building, the center pillars obstruct the moving space of the equipment, and inconvenience is brought to construction or subsequent use.

In order to reduce the number of center pillars in the box-type structural unit and to achieve a supporting effect on the beam, the applicant has found that in a box-type structural unit stacked in two layers one above the other, the box-type structural unit located at the upper layer can be used as a transfer layer, and a supporting structure occupying a small internal space is provided on the beam of the box-type structural unit at the upper layer. Specifically, a diagonal brace or a truss is arranged on the beam body of the upper-layer box-type structural unit.

In the modular building adopting the supporting structure, the beam stress of the upper-layer box-type structure unit is improved, and the beam stress of the upper-layer box-type structure unit can be shared by the supporting structure of the upper-layer box-type structure unit and transmitted to the side columns around the box-type structure unit, so that the middle columns of the lower-layer box-type structure unit, which are used for supporting the beam, can be removed, the number of the middle columns of the box-type structure unit is reduced, and when the box-type structure unit is spliced and combined to form the modular building, a larger inner space is formed, and the building requirement of a large space of a user is met.

Meanwhile, the second support structure is disposed on at least a portion of the top beam 130 of the lowermost box 10 (i.e., the third box 10) in the vertical direction, so that a larger internal space is created for the lowermost box 10 in the modular building formed by splicing and combining while sharing the stress from the bottom beam 120 of the second box 10, and thus a multi-storey large span space is created for the whole multi-storey box 10 when the modular building is formed by splicing and combining.

In some embodiments of the present application, optionally, a plurality of stacked cases 10 are butted along a horizontal direction (parallel to the direction indicated by the arrow Y in fig. 1), the number of the cases 10 is not less than 2, and the side posts 110 of two adjacent cases 10 are connected together.

Since the number of the center pillars 140 inside the housing 10 can be reduced, the modular building formed by splicing and combining a plurality of stacked housings 10 can have a large inner space without a spatial obstacle due to the presence of the center pillars 140 by butting the stacked housings in the horizontal direction. In the modular building as shown in fig. 1, when two cases 10 thus stacked one on top of the other in the vertical direction are horizontally combined by splicing, since the center pillar 140 at the top beam 130 where two adjacent cases 10 located below in the vertical direction are close to each other can be removed, the inner space of the modular building is a combination of the inner spaces of the two cases 10 without the hindrance of the center pillar 140, thereby achieving the construction requirement of a large space of the modular building.
