Abstract

The utility model discloses a moisture-proof and heat-proof solid wood structure floor board, wherein the purpose of which is to provide a moisture-proof and heat-proof solid wood structure floor board characterized in that the floor board is not easily cracked and warped. The utility model comprises a dash board, a surface base board, a core board and bottom boards, wherein the core board and the bottom boards are provided with spaced grooves, the bottom boards and the core boards are glued integrally with the surface base board and the dash board in the longitudinal and the transverse directions, and both side surfaces of a long edge of the core board are correspondingly provided with a recess and a tenon. The surface base board is made of at least two layers of multi-layer boards. The floor board has the advantages of high heat transfer speed, small deformation and little surface splitting, and is especially suitable in the north.

Description

Damp proofing and heat-resistant floorboard in solid wood structure

Technical field

The utility model relates to a kind of wood flooring, particularly a kind of moisture resistance heat-resisting wooden floor.

Background technology

North cold weather generally adopts heating, is provided with thermal source below the indoor floor of many top grades, and heating installation is transmitted on the floor, even step in winter so warm sensation is arranged also on the floor.This floor generally is made up of multilayer, is that the top layer is generally thinner topmost, and material is good, and is not only attractive in appearance but also wear-resisting, and price is higher; The second layer is the table substrate; The 3rd layer is central layer, and thicker, the bottom has groove, and the two sides on the long limit of central layer have corresponding groove and tenon, is base plate below again, is by being arranged in parallel with a gap each other with the isometric strip solid wood in floor, and becomes cross-like with the groove of central layer; Four layers of plank are bonding through adhesive, floor into strips, the floor of every strip is by cooperatively interacting between the groove of two sides, the long limit of central layer and the tenon, be spliced into large-area floor, the gap of heating installation between base plate and central layer and table substrate contacts, be transmitted to dash board by the table substrate, make the floor upper surface heating.Because dash board is thinner, add that the temperature difference on logical heating installation and obstructed heating installation floor is big, distortion is serious, because the effect of internal stress, so the often very easy cracking of dash board.Because base plate is by making with the isometric strip solid wood in floor, generally have 1-2 rice long, therefore the distortion of accumulation stack is very big, makes the floor that warpage take place in addition.Influence attractive in appearance and functional performance.

The utility model content

The utility model has overcome the shortcoming that exists in the existing product, and a kind of damp proofing and heat-resistant floorboard in solid wood structure of not easy to crack and warpage is provided.

In order to address the above problem, the utility model is achieved through the following technical solutions: comprise dash board, table substrate, central layer, base plate, central layer and base plate are provided with spaced trenches, base plate and central layer are in length and breadth to being one with table substrate, dash board gummed, two sides, long limit at central layer are shaped on corresponding groove and tenon, and the table substrate is to be made by two-layer at least composite board.Can also vertically be interrupted arrangement by base plate, horizontal adjacent bottom plates fracture staggers mutually.

It is fast to have a heat transfer rate according to the damp proofing and heat-resistant floorboard in solid wood structure of such scheme manufacturing, is out of shape the advantage little, that the surface is not easy to ftracture.

Description of drawings

Fig. 1 is the bottom view of damp proofing and heat-resistant floorboard in solid wood structure;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is that Fig. 1 is at the B-B sectional view.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1, Fig. 2, Fig. 3, be the structural representation of damp proofing and heat-resistant floorboard in solid wood structure.Comprise dash board 1, table substrate 2, central layer 3, base plate 4, central layer 3 and base plate 4 are provided with spaced trenches, and base plate and central layer are one to gluing together with table substrate 2, dash board 1 in length and breadth, are shaped on corresponding groove 5, tenon 6 in the two sides, long limit of central layer 3.And table substrate 2 is made up of three layers composite board, and the wherein two-layer lumber fibre direction and the lumber fibre direction of dash board 1 are perpendicular, such dash board 1 is because pining down of following two layer multi-layer plate transverse fibers limited the distortion of walking crosswise of dash board 1, and dash board 1 just is not easy cracking.In the arrangement of base plate 4, base plate 4 vertically is being interrupted arrangement, and horizontal adjacent bottom plates 4 fractures stagger mutually, makes base plate 4 discontinuous when distortion like this, and internal stress discharges easily, can reduce deflection greatly.Consider the intensity on floor simultaneously, the way that adopts horizontal adjacent bottom plates 4 fractures to stagger mutually solves.

Claims (2)

1, a kind of damp proofing and heat-resistant floorboard in solid wood structure, comprise dash board, table substrate, central layer, base plate, central layer and base plate are provided with spaced trenches, base plate and central layer are in length and breadth to being one with table substrate, dash board gummed, two sides, long limit at central layer are shaped on corresponding groove and tenon, and it is characterized in that showing substrate is to be made by two-layer at least composite board.

2, damp proofing and heat-resistant floorboard in solid wood structure according to claim 1 is characterized in that described base plate vertically is being interrupted arrangement, and horizontal adjacent bottom plates fracture staggers mutually.
