Problems solved by technology

[0003] With the development of the timber industry and the needs of the container industry for glulam, a large number of glulam has been applied to the container floor; due to the limitations of equipment and processing methods, the size of the existing glulam can only be limited by the production of glulam. However, it is impossible to manufacture glulam with a length dimension that meets the length requirements of the container. Therefore, the existing container floor needs to be assembled from multiple processed and formed glulam. Wide-bottom beams are set at the splicing position to support the glulam floor. When the length of the container is fixed, the smaller the size of the processed single floor, the more the number of single floors used. The container bottom frame setting The more wide-bottomed beams there are, this greatly increases the production cost of the container; therefore, how to process glulam with a larger format to apply to the container floor is an important problem faced by glulam when applied to containers.

Embodiment 1

[0039] like figure 2 As shown, the length of the product in this embodiment is 12403mm, the width is 305mm, and the thickness is 28mm, such as Figure 4 The tree species of the product unit strip shown is tussah, and the extension method in the grain direction adopts the finger joint method. The glue used for the width in the transverse grain direction and the extension in the grain direction is polyurethane glue, and it can also be hot melt adhesive or phenolic resin glue. like image 3 As shown, in order to increase the strength of use, the joints of the unit strips of the present invention are staggered by distances d1, d2, d3, d4, and d5, all of which are not less than 100 mm.

[0040] The product of this embodiment adopts the following production method:

[0041] a Sawing: According to the requirements, the solid wood boards that have been dried to 8%-12% are processed into unit strips with a width of 25.5mm, a thickness of 30mm and a length of 200-1500mm (such as Fi...

Embodiment 2

[0051] like Image 6 Shown, the present embodiment product is bamboo glulam, and product length is 8588mm, and width is 1160mm, and thickness is 28mm, and product unit bar is bamboo chip 61 (see Figure 7 ), the method of lengthening in the direction of the grain adopts the hooking method, and the glue used for the width of the horizontal grain and the lengthening in the direction of the grain is isocyanate glue, which can also be modified by tannin glue or melamine.

[0052] The specific manufacturing steps of the above-mentioned laminated materials are as follows:

[0053] a` sawing: the bamboo slices with a thickness of 4.2mm and a width of 30mm are soaked in preservatives and dried to a moisture content of 8%-12%. The smaller bamboo slices 621 and 622 are spliced ​​into the required width, and the bamboo slices are hooked and tenoned 611 at both ends of the length direction using a comb machine;

[0054] b`Sizing: apply glue to both sides and ends of the unit strip in th...

Abstract

The invention discloses a manufacturing method of a long-breadth laminted wood, which is intermittent continuous production. The invention also discloses the laminted wood manufactured by the method, and the laminted wood can be 5mm or any size larger than 5mm in length, can meet the requirement of length of a bottom plate of a container, and reduce the arrangement of a wide bottom crossbeam of the container so as to reduce the manufacturing cost of the container.

Description

technical field [0001] The invention relates to a wooden board and a manufacturing method thereof, in particular to a long-format laminated timber for a container floor and a manufacturing method thereof. Background technique [0002] Glulam has good physical and mechanical properties such as tensile and compressive resistance, and has the characteristics of small materials and good use, and has long been used for building structural beams and household floors. [0003] With the development of the wood industry and the demand for glulam in the container industry, a large number of glulam have been applied to the bottom of the container; due to the limitations of equipment and processing methods, the size of the existing glulam can only be limited by the size of the production of glulam. Therefore, the existing container bottom plates need to be assembled from multiple processed and formed laminated materials, which requires that the bottom frame of the container corresponds ...
