Background technique

Steel structure modular building is a new type of building form, which is composed of a series of complete modular units. The modular unit is prefabricated and finished in the factory, and then the complete modular unit is shipped to the site for splicing and installation. The steel structure module building is essentially the application of the construction concept of maximizing factory work and minimizing on-site work. Most of the work is done in the factory, and only assembly is required on site. The prefabrication rate is extremely high, and it is a high-end product of prefabricated buildings. Due to its own construction characteristics, it has outstanding advantages such as excellent production quality, fast construction speed, green environmental protection, saving manpower and material resources, and ensuring project quality. It is a new and emerging architectural form with broad development prospects.

The construction method of modular buildings is different from traditional buildings. The most critical step is to integrate complete modular units on site. Therefore, the connection nodes between modular units are extremely important. At present, domestic research on modular buildings is increasing, but the form of modular connection nodes is relatively lacking, which seriously restricts the development of modular buildings. Proposing a new type of inter-unit connection node, which can not only achieve fast and convenient on-site installation, no welding on site, but also meet the requirements of structural safety and reliable mechanical performance, is an urgent problem to be solved.

The technical solution adopted by the present invention to solve the technical problems existing in the known technology is as follows: a mortise-and-mortise plug-type modular building corner connection node, comprising a mortise piece and a mortise piece, and the mortise piece is provided with a horizontal connecting column plate and a The vertical tenon of the horizontal connecting column plate, the socket piece adopts a cuboid structure, and is provided with two bottom surfaces, two connecting beam sides and two exposed sides, and a bottom surface of the socket piece is provided with the A module column is connected to the other bottom surface of the mortise piece in the mortise groove matched with the tenon head, and the tenon head and the socket piece are connected by a bolt.

The tenon piece adopts a T-shaped structure.

The plug is provided with a larger diameter head and a threaded tail, the tail of the plug is threadedly connected with the socket, and the head of the plug is locked on the exposed side of the socket.

A backing plate is provided under the head of the latch.

The invention has the advantages and positive effects that the corner connection of the upper and lower module units of the module building can be realized, the structure is simple and reasonable, the welding is not required on site, the installation is convenient and quick, and it is an efficient and reasonable connection node form.

Detailed ways

In order to further understand the content of the invention, features and effects of the present invention, the following embodiments are exemplified and described in detail with the accompanying drawings as follows:

Please refer to FIG. 1 to FIG. 5 , a mortise-and-mortise plug-type modular building corner connection node includes a tenon piece 1 and a mortise piece 2, and the tenon piece 1 is provided with a horizontal connecting column plate 1-2 and a The vertical tenon 1-1 of the column plate 1-2, the socket part 2 adopts a rectangular parallelepiped structure, and is provided with two upper and lower bottom surfaces, two connecting beam sides and two exposed sides, and a bottom surface of the socket piece 2 is provided. There is a mortise groove 2-1 matched with the tenon 1-1, and a module column is connected on the other bottom surface of the mortise 2. The tenon 1-1 and the mortise 2 are connected by a bolt 4, so it is necessary to Pin holes 1-3 and 2-2 are provided on the tenon 1-1 and the socket 2.

In this embodiment, the tenon member 1 adopts a T-shaped structure. The plug 4 is provided with a head with a larger diameter and a threaded tail, the tail of the plug 4 is threadedly connected with the socket 2, and the head of the plug 4 is locked on the socket of the socket 2. On the exposed side, the part connecting the pin hole 2-2 on the socket 2 with the tail of the plug 4 should be a threaded fixing hole 2-2-1. A backing plate 3 is provided under the head of the plug 4 , and the backing plate 3 has a protective effect on the socket 2 .

During application, the socket 2 can be arranged above or below, and the application of the present invention is described as follows with the example that the socket 2 is arranged above:

In the factory, the upper module column 5 is welded on the upper bottom surface of the socket 2, and the two modular floor beams 6 are respectively welded on the two connecting beam sides of the socket 2 to form an upper module unit; the lower module column 8 is welded on the tenon The horizontal connecting column plate 1-2 of the component 1 is welded with a ceiling beam 7 on the side surfaces of the two connecting beams of the lower module column 8 to form a lower module unit.

During on-site construction, align the mortise 2-1 with the tenon 1-1, insert the tenon 1-1 into the mortise 2-1 smoothly, and then insert the pin 4, and the tail of the pin 4 is threadedly connected with the fixing hole 2-2-1 , and tighten it so that its head is in close contact with the backing plate 3, so far the upper and lower modular units are spliced. The upper and lower module units are connected to a reliable whole through the node area, and the connection nodes can meet the mechanical performance requirements of tensile, shear and bending resistance, and can realize no welding on site, and the installation is convenient and fast. The specific connection dimensions such as tenon and mortise can be calculated and adjusted according to the force of the node domain to meet the force requirements.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments. Under the inspiration of the present invention, personnel can also make many forms without departing from the scope of the present invention and the protection scope of the claims, which all belong to the protection scope of the present invention.
