[0002] The traditional wooden formwork of the square box is the same as the wooden formwork of the cylinder structure. It uses pure wood as the skeleton and superimposes solid wood as the outer edge working surface of the wooden formwork. Although such a wooden formwork ensures the rigidity of the wooden formwork, it also has the following disadvantages: The superposition of solid wood on the outer edge will consume more wood, and the superposition and processing of wood will consume a lot of man-hours. Due to the superposition of wood, the increase in the joint surface between the boards will affect the mold release, and the moisture content of wood is difficult to stabilize due to changes in air humidity.

Embodiment 1

[0033] as attached figure 1 As shown, a wooden formwork with a square box structure whose working surface is the inner wall surface, the solid wood strips 1 are spliced ​​and fixed together to enclose a quadrilateral skeleton, and the multilayer boards 2 are fixed on the skeleton to form an openable and closed square box. Laminate 2 is used as the working surface of the box, and plastic foam 3 is filled between the laminate 2 and the solid wood strip 1 . The solid wood strips 1 and the solid wood strips 1 can be connected with nails or falcons. The multi-layer board 2 and the solid wood strip 1 can be fixed by nails, or can be directly clamped together, and the multi-layer board 2 and the multi-layer board 2 can be connected by nails or glued together.

Embodiment 2

[0035] as attached figure 2 As shown, a wooden formwork with a square box structure whose working surface is the outer wall surface, the solid wood strips 1 are fixed together to form a cross-shaped skeleton, the multilayer boards 2 are fixed on the four edges of the skeleton, and the multilayer boards 2 surround a It is a square box, and the outer wall surface of the box is a working surface, and foam plastic 3 is filled between the solid wood strip 1 and the multi-layer board 2 .

Embodiment 3

[0037] A kind of preparation method of multi-layer board, see attached image 3 , including a brass board 202 and a wood board 201 , the wood board 201 is pasted on both sides of the brass board 202 .

[0038] The preparation method is as follows,

[0039] S1: Soak a 10mm thick wooden board and a 3mm thick brass plate in 0.1mol / L sodium hydroxide solution for 5 minutes, then soak in 0.1mol / L dilute hydrochloric acid solution for 5 minutes, and then place Ultrasonic treatment in deionized water for 20 minutes, and finally blow dry with airflow at 45°C to 50°C; the volume ratio of oxygen in the airflow is 15%, the proportion of nitrogen is 82%, and the humidity of the airflow is 35%, and the flow rate of the gas is 7m / s ;

[0040] S2: Dissolve 1 part of silica nanoparticles evenly in 300 parts of water-based glue, maintain the temperature of the water-based glue at 55°C, then put the wooden board 201 and the brass board 202 in the water-based glue, and make the wooden board on...

Abstract

The invention discloses a wooden mold of a square box structure. The wooden mold includes a plurality of solid wood strips, and further includes composite boards, the solid wood strips are connected together to form a skeleton, the composite boards are disposed on the periphery of the skeleton, the composite boards enclose a square box which can be opened and closed, and the inner wall or the outer wall of the box is a working surface; and when the inner wall of the box is the working surface, the skeleton is located outside the box, and when the outer wall of the box is the working surface, the skeleton is located in the box. The wooden mold of the square box structure has the following beneficial effects that compared with solid wood, the composite boards are less prone to absorbing water, cannot crack when used and are higher in accuracy, and more convenience and more economy are achieved compared with solid wood stacking.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a wooden mold with a square box structure. Background technique [0002] The traditional wooden formwork of the square box is the same as the wooden formwork of the cylinder structure. It uses pure wood as the skeleton and superimposes solid wood as the outer edge working surface of the wooden formwork. Although such a wooden formwork ensures the rigidity of the wooden formwork, it also has the following disadvantages: The superposition of solid wood on the outer edge will consume more wood, and the superposition and processing of wood will consume a lot of man-hours. Due to the superposition of wood, the increase in the joint surface between the boards will affect the mold release, and the moisture content of wood is difficult to stabilize due to changes in air humidity. Cracking or deformation of wooden formwork caused by control. Contents of the invention [0003] The present inventio...
