Description

Technical Field

[0001] This invention relates to the field of orthogonal glulam manufacturing technology, specifically a mold for manufacturing curved orthogonal glulam and a method for manufacturing curved orthogonal glulam. Background Technology

[0002] Cross-laminated timber (CLT) is a new type of wood building material. It is made by cross-laminated timber planks glued together, and the area and thickness can be customized. The characteristic of CLT is that it glues together timber with cross-grained and cross-grained wood to achieve better strength.

[0003] Currently, most cross-laminated timber is a large-panel structure, meaning the surface is flat.

[0004] If curved cross-laminated timber is to be produced, a custom-made curved panel is required to press the cross-laminated timber together. If the curvature of the cross-laminated timber needs to be changed, another curved panel with a corresponding curvature needs to be used to press the cross-laminated timber together. This method is costly, inefficient, and has limited versatility. Summary of the Invention

[0008] The suspension includes a lifting drive mechanism and a movable suspension. The lifting drive mechanism is connected to the top of the base, and the telescopic end of the lifting drive mechanism is connected to the movable suspension to drive the movable suspension to rise and fall.

[0009] The base frame includes a prism and a base. The base is connected to the bottom of the foundation. Both ends of the base are fixedly connected to the prism, and the top of the prism is rotatably connected to a rotating rod.

[0011] The second telescopic assembly comprises a plurality of second screw rod lifting devices, which are respectively connected to the base, and are used to drive the second screw rod lifting device to move up and down.

[0012] The top of the rotating rod head supports a supporting plate, and the gap between the supporting plate and the plurality of roller pressing heads is used to place the orthotropic glued wood that has been coated with glue and is to be pressed.

[0013] When the first screw rod moves downward, the roller pressing head is used to apply pressure to the orthotropic glued wood that has been coated with glue and is to be pressed and the supporting plate, so that the orthotropic glued wood and the supporting plate are deformed, and the deformed orthotropic glued wood and the supporting plate are supported by the top of the rotating rod head and the supporting head.

[0018] As a further improved technical solution of the present application, the base comprises a bottom plate, a cross beam and vertical beams, the bottom plate and the cross beam are each provided with one, the cross beam is connected between the top portions of the two vertical beams, and the bottom plate is connected between the bottom portions of the two vertical beams.

[0019] The lifting drive mechanism is connected to the lower surface of the cross beam.

[0028] The present application has the following advantages:

[0029] 1. The supporting plate installed in the present application is supported by the second telescopic assembly, and the bending degree of the orthogonal laminated wood and the supporting plate can be changed by changing the stroke of the first lead screw in the first telescopic assembly and the second lead screw in the second telescopic assembly.

[0056] Step 2, as Figures 1-4 , the supporting plate 6 is placed on the rotating rod head 503 at the top of all the prisms 501, and the orthogonal glulam 7 to be pressed and combined is placed on the supporting plate 6, at this time, the supporting plate 6 is supported on the top of the rotating rod head 503;
