Abstract
A light high-strength sandwich plate comprises a lower surface plate and an upper surface plate, wherein the lower surface plate and the upper surface plate are connected through edge vertical plates positioned on two sides to form a frame structure with a cavity; the cavity of the frame structure is divided into a plurality of spaces by at least one neutral plate, each space is provided with a support frame, the left side and the right side of each support frame are abutted against the side wall of the corresponding side, and the upper side and the lower side of each support frame are respectively abutted against the inner side surface of each abutting plate; the lateral surface of butt plate with the inner wall in space meets, the utility model discloses a poplar material preparation forms, and itself just has light in weight's advantage, adopts and adds the support frame of establishing the cross shape in the frame, has reduced the weight of solid multiply wood before and does not reduce its structural strength, accomplishes the effect that had both reduced weight right holding strength, still sets up the butt plate that is used for increasing lifting surface area in addition below the support frame, guarantees joint strength.
Description
Technical Field
The utility model relates to a light-duty high strength sandwich panel belongs to sandwich panel technical field.
Background
The existing sandwich plate (sandwich plate) is a composite plate which is formed by adding a core layer between two surface plates and combining the core layer through bonding or other modes, has good designability, and is characterized by having good comprehensive use performance and lighter weight while obtaining the performance of a design target, and having higher material utilization rate.
Therefore, how to efficiently utilize a large amount of domestic fast-growing wood resources, particularly poplar resources, how to produce a material with a larger volume and meeting the requirement under the consumption of the same wood volume, and simultaneously having higher physical and mechanical properties is a problem in the technical field of the existing wood structure.
Based on the above problems, the inventors propose a lightweight high-strength sandwich panel.
Disclosure of Invention
Technical problem to be solved
The utility model aims at providing a light-duty high strength sandwich panel based on above-mentioned idea.
(II) technical scheme
The utility model realizes the purpose through the following technical proposal, a light high-strength sandwich plate comprises a lower surface plate and an upper surface plate, wherein, the lower surface plate and the upper surface plate are connected through edge vertical plates positioned at both sides to form a frame structure with a cavity;
the cavity of the frame structure is divided into a plurality of spaces by at least one neutral plate, each space is provided with a support frame, the left side and the right side of each support frame are abutted against the side wall of the corresponding side, and the upper side and the lower side of each support frame are respectively abutted against the inner side surface of each abutting plate;
the outer side surface of the abutting plate is connected with the inner wall of the space.
Furthermore, the shape of the support frame is a cross frame.
Furthermore, the support frame is in a cross shape formed by extruding poplar wood powder.
Furthermore, the joints of the support frame, the abutting plate, the middle vertical plate, the lower surface plate and the upper surface plate are connected and matched by adhesive layers.
Further, the lower surface plate, the upper surface plate, the side vertical plate, the middle vertical plate and the abutting plate are all made of poplar materials.
Compared with the prior art, the utility model has the advantages that:
adopt poplar timber material preparation to form, itself just has light in weight's advantage, adopts to add the support frame of establishing the cross shape in the frame, has reduced the weight of solid multiply wood before and does not reduce its structural strength, accomplishes the effect that both reduces weight right side holding strength, still sets up the butt plate that is used for increasing the lifting surface area in addition below the support frame, guarantees the joint strength.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
