Description

Technical Field

[0001] This application relates to a modular connection structure for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to the process of prefabricating components such as floor slabs and stairs in a factory, transporting them to the construction site, and then connecting these components to complete the overall assembly of the building. Because prefabrication in the factory allows for assembly line production, the quality of the components is guaranteed, and production costs are lower. Therefore, the most important aspect of prefabricated construction is the effective connection of these components. Currently, connecting plates and bolts are commonly used. This assembly method is relatively simple and efficient, but it may present construction difficulties for some internal prefabricated components. Most importantly, this structural form has relatively poor seismic resistance, and auxiliary methods are now being used to minimize this problem. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a modular connection structure for prefabricated buildings, comprising a lower connecting part, an upper connecting part on the lower connecting part, a connecting screw between the upper and lower connecting parts, a lower connecting threaded section on the lower connecting part that is threadedly connected to the connecting screw, and an inner mounting cavity within the upper connecting part. The connecting screw is inserted into the inner mounting cavity, and an inner connecting mortar section is filled into the inner mounting cavity. In this application, one end of the connecting screw of the intermediate connecting part is threadedly connected to the lower connecting part, while the top is reinforced by filling with cement mortar to form an inner connecting mortar section, thereby improving the connection, enhancing structural stability, and increasing construction efficiency. Due to the cement concrete structure used here, compared to steel structure connections, its seismic resistance is significantly improved.

[0004] Preferably, a number of auxiliary connecting nuts are provided on the connecting screw located in the inner connecting mortar section.

[0005] Preferably, several reinforcing connecting rods are provided on the outside of the auxiliary connecting nut.

[0006] Preferably, a lower connecting plate is provided on the upper part of the lower connecting part, and the lower connecting thread section is provided on the lower part of the lower connecting plate. An upper connecting plate is provided on the lower part of the upper connecting part, and the connecting screw passes through the upper connecting plate, the lower connecting plate, and the lower connecting thread section in sequence from top to bottom.

[0007] Preferably, an intermediate connecting plate is provided between the upper connecting plate and the lower connecting plate, and annular grooves are provided on the upper and lower sides of the intermediate connecting plate, with annular sealing rings provided in the annular grooves.

[0008] Preferably, an intermediate connecting plate is provided between the upper connecting plate and the lower connecting plate. Annular grooves are respectively provided on the upper part of the intermediate connecting plate and the upper part of the lower connecting plate, and an annular sealing ring is provided within each annular groove. The intermediate connecting plate in this application can improve the sealing effect, and the use of two different types of annular sealing rings allows the intermediate connecting structure to act as a buffer between the upper and lower connecting plates.

[0009] Preferably, a number of vertical positioning rods are provided on the intermediate connecting plate, and positioning holes that cooperate with the vertical positioning rods are provided on the upper connecting plate.

[0010] Preferably, there are two vertical positioning rods arranged opposite each other, and they are semi-circular cylinders in shape. The positioning hole is a circular hole formed on the central connecting plate and fitted into the semi-circular cylinder. By setting vertical positioning rods, this application can more conveniently fix the position of the upper connecting part. Since both the lower and upper connecting parts are part of the assembly during construction, the vertical positioning rods provide a good structural reference for the overall positioning of the upper connecting part after the lower connecting part is assembled.

[0011] Preferably, the lower connecting threaded section is a connecting nut, and the lower connecting threaded section is fixedly welded to the lower part of the lower connecting plate.

[0012] This application can bring the following beneficial effects: 1. In this application, one end of the connecting screw of the intermediate connector is connected to the lower connecting part by thread, while the top is formed by filling cement mortar to form an inner connecting mortar section to enhance the connection, improve the stability of the structure, and increase the construction efficiency. Due to the cement concrete structure here, compared with the steel structure connection, its seismic resistance is greatly improved.

[0013] 2. The intermediate connecting plate in this application can improve the sealing effect, and the intermediate connecting structure can play a buffering role for the upper and lower connecting plates by setting two types of annular sealing rings.

[0014] 3. By setting a vertical positioning rod, this application can more conveniently fix the position of the upper connecting part. Since both the lower and upper connecting parts are part of the assembly during construction, the setting of the vertical positioning rod provides a good structural reference for the overall positioning of the upper connecting part after the lower connecting part is assembled.
