Description

TECHNICAL FIELD

[0002] Building Information Modeling, referred to as BIM, is a computer tool widely used in architecture, engineering and civil engineering. Modular building is a kind of building technology that adopts factory batch production, direct hoisting, splicing and installation at the construction site. Compared with traditional building projects, modular building has the advantages of shortening the construction period at the construction site, reducing the number of workers at the construction site, and reducing construction waste. With the development and progress of society, and the pursuit of green, environmental protection and energy saving concept, modular building is more and more recognized and accepted, especially in the past ten years, the development and demand of multi-story, high-rise and super high-rise modular housing are more and more extensive, and the connection between modular buildings is becoming more and more important.

[0003] Modular building is commonly known as box building, that is, each unit module is similar to a box with six faces. Since modular building is composed of unit modules in the shape of a box, most of them are stacked by hoisting during the specific stacking process. However, the current hoisting equipment will produce a large swing when connecting the building modules, which may cause damage to the inside of the module, and after hoisting is completed, the construction personnel need to disconnect, which is low in hoisting efficiency. For the stacked building modules, a fixing device is often needed to stably connect them. Currently, hinges, shafts, screws and other connecting means are used to connect these modules during installation. During building construction, construction workers need to spend a lot of time installing bolts, and when the building needs to be disassembled, construction workers need to spend a lot of time again to disassemble the bolts. Moreover, construction workers often need to install or disassemble bolts in the air, and the angle of construction workers working in the air is very limited, making it extremely difficult to disassemble some bolts or even unable to ensure that the bolts are tightened well, thereby affecting the stability and safety of the building. Therefore, there is a need for an effective automatic locking and disassembling construction method for the transportation and stacking of building modules on the market. SUMMARY

[0034] Please refer to Figures 1 to 10The present invention provides a technical solution: a modular building based on BIM, including a hoisting plate 1 and a building module 2. The upper surface of the building module 2 is provided with a plurality of locking pin mechanisms 200 for easy locking. The lower side of the hoisting plate 1 is provided with a plurality of locking mechanisms 100 that lock with the locking pin mechanisms 200. The upper left and right sides of the building module 2 are provided with a plurality of locking mechanisms 300 for easy locking with other building modules 2. The locking mechanism 300 is provided with a gain mechanism 400 to improve the locking effect. The lower side of the locking mechanism 300 is fixedly connected to the surface of the building module 2 with a plurality of L-shaped pressure blocks 3. The L-shaped pressure blocks 3 are fixedly provided with L-shaped grooves 4 inside.

[0035] The locking mechanism 100 includes a fixing block 101 and a wedge block 106. The locking mechanism 100 locks the pin mechanism 200 through the fixing block 101 and the wedge block 106. The gain mechanism 400 includes a mating part 402 and a plug rod 411. The gain mechanism 400 increases the stability of the locking of the snap-fit ​​mechanism 300 through the mating part 402 and the plug rod 411. The upper end face of the fixing block 101 is fixedly connected to the lifting plate 1. Figure 1 As shown, a vertical groove 102 is fixedly formed in the middle of the fixing block 101, and a horizontal groove 103 is fixedly formed on the left side of the interior of the fixing block 101. The horizontal groove 103 communicates with the vertical groove 102. A sliding rod 104 is slidably connected to the left side of the fixing block 101. The sliding rod 104 moves inside the horizontal groove 103. A wedge block 106 is fixedly connected to the right end of the sliding rod 104. A return spring 105 is sleeved on the surface of the sliding rod 104. One end of the return spring 105 is fixedly connected to the left end face of the interior of the horizontal groove 103, and the other end of the return spring 105 is connected to the wedge block 106.

The hoisting equipment controls the hoisting plate 1 to move downwards, and the fixed shaft 201 inserts into the vertical groove 102. The wedge block 106, under pressure, moves outwards. When the wedge block 106 contacts the lower arc-shaped section of the arc-shaped slider 204, the arc-shaped slider 204 releases pressure on the wedge block 106. The wedge block 106 resets under the action of the return spring 105, and the arc-shaped slider 204 moves upwards under thrust. Figure 3As shown, the locking mechanism 100 drives the pin mechanism 200 to move, and the pin mechanism 200 drives the building module 2 to a designated position.

When the upper end of the arc surface slider 204 contacts the inclined surface of the wedge block 106, the wedge block 106 resets under the action of the wedge block 106, thereby releasing the locking operation of the locking mechanism 100 on the pin mechanism 200.
