Description

Self-locking mortise and tenon modular building connection nodes

technical field

The invention relates to a central column connection node of upper and lower module units in a modular building, more specifically, the connection node is suitable for the central column, side column and corner column of the module connection.

Background technique

The steel structure modular building is a highly prefabricated building. It divides the traditional house into a single room or a certain three-dimensional building space as a building module unit. It can be prefabricated and processed in the factory in advance, and transported to the site for installation and connection after completion. With the advantages of fast construction speed, green environmental protection, and saving manpower and material resources, it is a new emerging architectural form with broad development prospects.

The modular building is different from the traditional building construction method. The traditional building generally has a single column and four beams at the middle node, while the modular building has its module units processed in the factory and transported to the site for assembly, which results in a modular building in the middle. There are "eight columns and sixteen beams" connection nodes at the connection nodes. After all, there is no welding space at the connection position, and the connection method is difficult to deal with, which seriously restricts the development of modular buildings. At present, there are very few connection methods for domestic modular buildings, and the research is very limited. limited. It is an urgent problem to propose a new type of steel structure module connection node, which can achieve fast and convenient on-site installation, minimize welding to achieve no welding on site, and meet the requirements of structural safety and reliable mechanical performance.

Contents of the invention

The invention mainly provides a connection node of upper and lower module units in a modular building, which can meet the requirements of fast construction speed, no welding on site, simple structure and convenient installation. Technical scheme of the present invention is as follows:

A self-locking mortise and tenon type modular building connection node, including a self-locking tenon, a self-locking mortise and a mortise sleeve, used to connect the upper module column and the corresponding lower module column, wherein the self-locking The sockets include a plurality of upper sockets and a plurality of lower sockets, the upper sockets are respectively arranged on the lower ends of the upper columns of the upper module columns, and the lower sockets are respectively arranged on the upper ends of the lower columns of the lower module columns; The locking tenon includes a plurality of upper tenons and a plurality of lower tenons fixedly connected together; part or all of the outer surfaces of the upper tenons and the lower tenons are stepped, and part or all of the inner surfaces of the upper tenons and the lower tenons are also stepped. It is stepped, and the steps of the corresponding upper mortise and upper mortise and the corresponding lower mortise and lower mortise match each other.

As a preferred embodiment, a shank sleeve is provided on the outer surface of each of the upper shank and the lower shank.

The invention can solve the connection problem of the upper and lower modular units in the modular building. The structure of the nodes is simple and reasonable, and can achieve fast and convenient installation, which is a reasonable way to connect nodes.

detailed description

As shown in FIG. 1 , the self-locking mortise and tenon type modular building connection node of the present invention includes a mortise 7 , a mortise connection plate 8 , a mortise 9 , a mortise connection plate 10 and a mortise sleeve 11 . Among them, the mortise 7 is welded on the mortise connecting plate 8, the mortise 9 is first welded together with the mortise connecting plate 10, then the mortise sleeve 11 is welded to the mortise connecting plate, and then the whole is welded to the upper module column 1 , and finally the floor beam 2 is welded to the upper module column 1 and the socket 11 respectively. The remaining modular columns are treated in the same way. This moment, the modular unit with the shank is finished.

The opposite sides of the self-locking mortise are stepped. The number of steps and the size of the mortise can be adjusted according to the force of the connection node, and must be completely matched with the mortise. There is a gap between the two rows of mortise. During the construction process, the upper module passes through. Gravity or some kind of measures allow the tenons to be inserted into the mortise. During the insertion process, the gap between the tenons can provide space for the two rows of tenons to expand and contract inward. After all the tenons are inserted into the mortise, the tenons will automatically return to their original positions. It is automatically locked with the shank, and the upper and lower module units are connected. Through the joint action of self-locking mortise, self-locking mortise and casing, the connection node can meet the mechanical performance requirements of tensile, shear and bending resistance, and can realize no welding on site.

As shown in Figure 2 and Figure 3, there is a certain gap between the two rows of tenons. When the upper and lower modules are transported to the site for assembly, first place the self-locking tenons on the top of the lower module unit column, and then hoist the upper module unit to the installation Under the gravity of the upper module unit, the mortise shrinks inward. After the mortise is fully inserted into the mortise, the mortise automatically returns to its original position, and the tenon and mortise are automatically locked. At this point, the upper and lower module units are installed.

Figure 5 shows the shape of the mortise and mortise after the connection is completed. Through the joint action of the self-locking mortise, self-locking mortise and sleeve, the joint can meet the mechanical performance requirements of tensile, compressive, shear and bending resistance , the number of mortises for the center column, side column and corner column is 8, 4 and 2 respectively, and the upper and lower tenons of the tenon connecting plate are arranged symmetrically. Bi-directional, the arrangement direction of half of the mortise can be adjusted, that is, it can be rotated 90 degrees, and at this time, the inner mortise of the column can be adjusted accordingly. The mortise and tenon length of the self-locking joint needs to be determined after calculation.
