[0001] The invention relates to the technical field of cross-laminated timber manufacturing, in particular to a mold for manufacturing curved surface cross-laminated timber and a method for manufacturing curved surface cross-laminated timber. Background Art

[0002] Cross-laminated timber (CLT) is a new type of wood building material. It uses wood squares stacked orthogonally and glued together to form solid wood panels. The area and thickness can be customized. The characteristic of cross-laminated timber is that the wood with staggered horizontal and vertical grains is glued together to achieve better strength.

[0003] Currently, most cross-laminated timber structures are large-panel structures, that is, the surface is flat.

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

[0012] The top of the rotating rod head is supported by a support plate, and the gap between the support plate and the plurality of roller pressing heads is used to place the cross-laminated timber that has been coated with glue and is to be pressed;

[0013] When the first screw moves downward, the roller pressure head is used to apply pressure to the orthogonal glued timber and the supporting plate that have been coated with glue and are to be pressed, thereby causing the orthogonal glued timber and the supporting plate to deform. The deformed orthogonal glued timber and the supporting plate are supported by the rotating rod head and the top of the supporting head.

[0046] The top of the rotating rod head 503 supports a support plate 6, and the gap between the support plate 6 and the plurality of roller pressing heads 202 is used to place the cross-laminated timber 7 that has been coated with glue and is to be pressed.

[0047] like Figure 5 When the first screw rod 2011 moves downward, the roller pressure head 202 is used to apply pressure to the orthogonal glued timber 7 and the supporting plate 6 that need to be pressed, thereby causing the orthogonal glued timber 7 and the supporting plate 6 to deform. The deformed orthogonal glued timber 7 and the supporting plate 6 are supported by the rotating rod head 503 and the top of the supporting head 302.

[0048] The first telescopic assembly 2, the second telescopic assembly 3, the suspension 4, and the base frame 5 are all multiple and the number is the same; the multiple suspensions 4 are evenly spaced along the width direction of the base 1, and the multiple base frames 5 are evenly spaced along the width direction of the base 1.

[0049] Each suspension 4 includes two lifting drive mechanisms 401 and a movable suspension 402 , and the telescopic ends of the two lifting drive mechanisms 401 are respectively connected to the two ends of the movable suspension 402 .

[0051] The lifting drive mechanism 401 adopts a hydraulic cylinder, the cylinder body of the hydraulic cylinder is connected to the top of the base 1, and the telescopic rod of the hydraulic cylinder is connected to the movable suspension 402.

[0052] like Figure 2The base 1 includes a bottom plate 101, a cross beam 102 and a vertical beam 103, each of the bottom plate 101 and the cross beam 102 is provided with one, the cross beam 102 is connected between the tops of the two vertical beams 103, and the bottom plate 101 is connected between the bottoms of the two vertical beams 103; the lifting drive mechanism 401 is connected to the lower surface of the cross beam 102; the base 502 is connected to the upper surface of the bottom plate 101.

[0053] The first screw lift 201 is a manual screw lift or an electric screw lift; the second screw lift 301 is a manual screw lift or an electric screw lift.

[0054] This embodiment also provides a method for manufacturing a mold for manufacturing curved surface cross-laminated timber, comprising:

[0055] Step 1, start all the lifting drive mechanisms 401, and multiple lifting drive mechanisms 401 are retracted to the shortest state. The telescopic ends of the lifting drive mechanisms 401 drive multiple movable suspensions 402 to move upward together, so that the roller pressure heads 202 at the lower ends of the first screw rods 2011 in the multiple first telescopic components 2 are all away from the supporting plate 6, and then the telescopic ends of the lifting drive mechanisms 401 stop moving upward;

[0056] Step 2: Figure 1-4 , the support plate 6 is placed on the rotating rod heads 503 at the tops of all the prisms 501, and the cross-laminated timber 7 to be pressed is placed on the support plate 6. At this time, the support plate 6 is supported on the top of the rotating rod heads 503;

[0057] Step 3, according to the bending degree of the curved surface cross-laminated timber, the extension lengths of the first screw rod 2011 in the first telescopic assembly 2 and the second screw rod 3011 in the second telescopic assembly 3 are respectively adjusted; after the adjustment is completed, all the lifting drive mechanisms 401 are started, the lifting drive mechanism 401 drives the movable suspension 402 to move downward, the movable suspension 402 drives the first telescopic assembly 2 to move downward, the first screw rod 2011 in the first telescopic assembly 2 moves downward, and the roller pressure head 202 at the lower end of the first screw rod 2011 applies pressure to the cross-laminated timber 7 and the supporting plate 6 that have been coated with glue and are to be pressed, thereby causing the cross-laminated timber 7 and the supporting plate 6 to deform, and the deformed cross-laminated timber 7 and the supporting plate 6 are supported by the rotating rod head 503 and the top of the supporting head 302; the lifting drive mechanism 401 adopts a hydraulic cylinder, and a pressure sensor is installed in the hydraulic cylinder, and the pressure value detected by the pressure sensor is used to control the downward force of the lifting drive mechanism 401;

[0058] Step 4: Figure 5-7As shown, after pressure is applied to the cross-laminated timber 7 and the supporting plate 6 for a period of time, the glue in the cross-laminated timber 7 is solidified, and the lifting drive mechanism 401, the first telescopic assembly 2 and the second telescopic assembly 3 are reset to obtain the curved cross-laminated timber.

[0059] The supporting plate 6 installed in the present invention is supported by the second screw rod 3011 of the second telescopic assembly 3. The curvature of the cross-laminated timber 7 and the supporting plate 6 can be adjusted separately by the second telescopic assembly 3 connected thereto and the first telescopic assembly 2 above. The installed supporting plate 6 can realize processing of curved surfaces with different curvatures and realize repeated use. The supporting plate 6 is made of a flexible plastic plate for easy molding.

[0060] Both ends of the base 1 of the present invention are connected to a lifting drive mechanism 401. When the orthogonal glued timber 7 is extruded, the first screw 2011 is driven downward by the lifting drive mechanism 401, and the roller pressure head 202 applies pressure to the orthogonal glued timber 7 that has been coated with glue and is to be pressed and the supporting plate 6, thereby causing the orthogonal glued timber 7 and the supporting plate 6 to be deformed. The deformed orthogonal glued timber 7 and the supporting plate 6 are supported by the rotating rod head 503 and the top of the supporting head 302.

[0061] When it is necessary to prepare cross-laminated timber 7 with different curvatures, it is only necessary to adjust the different heights of the first screw 2011 of the first screw lifting device 201 and the different heights of the second screw 3011 in the second screw lifting device 301, so as to achieve the pressing of cross-laminated timber 7 with different curvatures. It should be noted that the length of the screw extension in this article can be experimented in advance according to the cross-laminated timber with different curvatures to obtain specific results, and then the results can be input into the control system to control the first screw lifting device 201 using an electric screw lifting machine, the second screw lifting device 301 using an electric screw lifting machine, and the lifting drive mechanism 401 using a hydraulic cylinder. When the lifting drive mechanism 401 using a hydraulic cylinder is controlled, the flow rate and pressure of the liquid are controlled by a flow control valve to control the operation of the hydraulic cylinder, and the control method adopts the existing technology. In addition, the height of the lower end of the first screw rod 2011 in the first screw rod lifting device 201 located at the top and the height of the upper end of the second screw rod 3011 in the second screw rod lifting device 301 located at the bottom are matched and controlled, thereby ensuring that the top curvature and bottom curvature of the orthogonal glued timber 7 are consistent. The specific height setting can be obtained through multiple experiments.

[0062] Before preparing the curved orthogonal glued timber, the present invention needs to prepare multiple wooden board layers first, that is, glue is applied to the sides of multiple strip wooden boards, and then the multiple strip wooden boards are glued side by side horizontally to form a wooden board layer of about 10-15 mm, and then the surfaces of the multiple wooden board layers are glued, and the multiple wooden board layers are staggered according to the horizontal and vertical grains and arranged up and down, and then placed on a supporting plate 6 to prepare the curved orthogonal glued timber.

[0063] The mold and manufacturing method for manufacturing curved cross-laminated timber can be applied to the pressing of cross-laminated timber 7 with different curvatures. Compared with the existing method, the mold and manufacturing method have low cost, high efficiency and good versatility.

[0064] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
