Description

Three-side connecting structure of building board

Technical Field

The utility model relates to a panel connected mode, in particular to trilateral connection structure of building board.

Background

The wood as a natural material has good air permeability, environmental protection and enough supporting strength, and also becomes a continuous building material under the condition of establishing a virtuous cycle tree planting mechanism. The fire-resistant time performance of the wooden beam column is proved to be not inferior to that of the steel frame structure in the aspect of fire prevention. Along with the improvement of environmental awareness of people and the requirements for residential houses, the wooden building structure is more and more favored by people. As a panel building, a large panel member is required for a wall panel or a roof, and the length of the panel member can reach several meters, so that rapid construction on site is facilitated, and therefore, how to make the connected panels have a firm connection structure which is convenient for construction is an important part for promoting the development of a wooden building.

In the prior art, the large-scale plates and the wood structure walls are connected and fixed in a metal connecting piece, a wood screw connection, a wood tenon connection and the like, and in the connecting and fixing modes, the metal and wood screw connection is inconvenient to operate, the overall strength is low, and the durability is poor.

In a plate building, three plates are often required to be butted to form a three-surface extending structure, for example, an upper plate and a lower plate are butted with a horizontal plate to form a wall and a horizontal partition structure. At this time, the conventional wood tenon structure cannot form a three-side butt joint structure.

In addition, the tenon and mortise are processed on the large-size plate or the wall body after the wood tenon connection, the wood tenon connection needs a crane for hoisting during the connection, and the operation is difficult during the hoisting butt joint and the tenon and mortise fixing of the large-size plate or the wall body because the tenon and mortise require tight matching. For the connecting edge of a long plate, tight tenon-and-mortise combination is guaranteed, and accumulated errors cannot exist in the length of several meters, so that the two plates are required to be pressed and inserted through an external force hammer when being butted, and the method can hardly be realized in practice. Even if the traditional dovetail groove and dovetail insert structure is adopted, the problem of difficult butt joint also exists.

Another problem with the sheet material connecting structure is that the two sheets connected to each other are locked to each other in one direction, and easily pulled off in the other direction. For example, the traditional dovetail groove and dovetail insert structure are locked in the vertical direction, and are easy to pull out in the horizontal or vertical direction. It is an ideal connection structure if the locking in the three-dimensional direction can be realized after the plugging.
