Technical Field

[0001] The utility model relates to the technical field of installation, in particular to a node structure at a corner of an exterior wall of a fiber cement board. Background Art

[0002] Fiber cement board is a board made of cement as the basic material and gelling agent, and mineral fiber cement and other fibers as reinforcing materials. It is made through pulping, molding, and curing processes. It has functions such as fire resistance, waterproofing, sound insulation, and thermal insulation. When fiber cement boards are used as exterior walls of wooden structures, it is usually necessary to connect and assemble two fiber cement boards at an angle.

[0003] However, the current assembly method generally connects two fiber cement boards by screws or rivets. This method requires driving the screws or rivets into the fiber cement board, which can easily cause damage to the fiber cement board and affect its use. In addition, during assembly, external tools are required, which makes the operation cumbersome and the assembly efficiency low. Utility Model Content

[0013] Preferably, each end of the fiber cement board body is provided with a notch, and the notch is slidably connected to or separated from the corresponding fixing plate and positioning plate.

[0014] Compared with the existing technology, the advantages of the fiber cement board exterior wall corner node structure provided by the utility model are:

[0015] The utility model rotates the bidirectional screw rod by turning the knob, so that the two movable plates move toward each other, and the two positioning plates on the same side can be pulled toward each other through the corresponding connecting plates and connecting blocks until they are tightly pressed into the recesses on the fiber cement board body.

[0025] The positioning assembly is used to press the two positioning plates 4 on the same side against the upper and lower sides of the corresponding fiber cement board body 2; the positioning assembly includes two cavities 5 symmetrically opened in the fixing frame 1, and a bidirectional screw rod 6 is installed in the two cavities 5 for common rotation, a knob 10 is fixedly installed on the top of the bidirectional screw rod 6, and the surface of the bidirectional screw rod 6 is reversely threadedly connected to two movable plates 7, and the two movable plates 7 are respectively placed in the two cavities 5, and two connecting plates 8 are fixedly installed on the opposite sides of the two movable plates 7, and the connecting plates 8 are movable through the surface of the corresponding cavity 5 and extend to the outside of the fixing frame 1, and each connecting plate 8 extending to the outside of the fixing frame 1 is fixedly installed with a connecting block 9, and the connecting block 9 is connected to the corresponding positioning The ends of the plates 4 are fixed. When connecting the two fiber cement board bodies 2 at the corners, first insert the two fiber cement board bodies 2 between the corresponding two fixed plates 3, and then use an external tool to insert it into the hexagonal groove on the knob 10. Turn the knob 10 to rotate the bidirectional screw rod 6, so that the two movable plates 7 move toward each other, and then the two positioning plates 4 on the same side can be pulled toward each other through the corresponding connecting plates 8 and connecting blocks 9 until they are tightly pressed against the recesses 13 on the fiber cement board body 2.
