Abstract

The utility model relates to a solid wood composite ground heating floor, which is formed by compounding a face board, a shim board, a core board and a bottom board into integration from the top down, wherein the core board is composed of a plurality of plates alternately provided with certain longitudinal spaces which form transverse channels of the floor. The bottom board is composed of a plurality of bar boards alternately provided with certain transverse spaces which form longitudinal channels of the floor. The longitudinal channels of the bottom board and the transverse channels of the core board are crosswise communicated to form a net-shaped channel of the floor. Mutually vertical and crisscross fibers of adjacent boards can avoid deformation and crack by heat and wet. The floor is laid on keel frames between which heating pipes are positioned, so heat of the heating pipes fully flows in the boards via the net-shaped channel and is conducted to the skin layer of the floor, so that the floor can be quickly heated up with favorable ground heating effects.

Description

Wood composite floor heating floorboard

Technical field

The utility model relates to a kind of as the ornamental wooden floor in flooring, especially for the wood composite floor heating floorboard of ground heating.

Background technology

In recent years, along with the raising of living standards of the people, the ground decoration in the room uses wooden floor more at large; Particularly winter cold the northern area of China and part southern area, solid wood geothermal energy floor is more and more accepted by people.This heating floor is laid the steam heating pipe top of flooring, and heat spreads from bottom to top by the floor, and whole room is evenly heated up, and has overcome the defective that traditional steam heat formula steam heating pipe causes indoor changes in temperature inequality easily, makes the people feel more comfortable.But the shortcoming of present heating floor is to be heated easily to cause that the solid wood monomer shrinks the distortion that warps.

Summary of the invention

The purpose of this utility model provide a kind of can effectively overcome because of variations in temperature warp the distortion wood composite floor heating floorboard.

By panel, backing plate, central layer and base plate each layer be composited one, wherein, several plates with certain longitudinal pitch alternately be made of from top to bottom by central layer for this heating floor, and this longitudinal pitch forms the interconnection on floor; Base plate is made of with certain horizontal spacing alternately several stripe board, and this horizontal spacing forms the vertical passage on floor; The vertical passage of base plate communicates with the interconnection of central layer is crisscross, forms the netted passage on floor.

In addition, the downside of backing plate can be laid with lateral trench, and corresponding one by one the coincideing of each interconnection of each groove and central layer links to each other.This scheme makes interconnection extend to backing plate, and heat-transfer effect is better.

The periphery of this heating floor is processed with tenon, the groove that can peg graft and piece together mutually with adjacent floor.

In sum, the laminate material is gluing is combined into one by four on this floor, because the fiber of adjacent each sheet material is orthogonal, crisscross, when environment temperature or humidity variation, this cross structure makes all directions balancing of stresses on floor, therefore can avoid producing the problem of distortion, cracking, contraction, expansion, arch camber.Central layer each plate and each stripe board of base plate between arrange in length and breadth, form the netted passage that communicates in length and breadth simultaneously.This floor is laid on the keel frame, and the heating pipe on ground is between keel; The heat of heating pipe is fully circulated in plate by netted passage and conducts to the top layer on floor, is heated up rapidly in this floor, and the ground thermal effect is very desirable.

Description of drawings

Fig. 1 is the perspective view of this wood composite floor heating floorboard.

Fig. 1 (1) is the A-A sectional view of Fig. 1.

Fig. 2 (1)～Fig. 2 (4) represents this heating floor split structural representation of each layer from top to bottom.

Fig. 3 is the upward view of Fig. 1.

According to Fig. 1 and in conjunction with shown in Fig. 2 (1)～Fig. 2 (4), this heating floor is followed successively by panel 1, backing plate 2, central layer 3 and base plate 4 from top to bottom, more than each layer is gluing is combined into one; Wherein the downside of backing plate 2 has lateral trench 21[referring to 2 (2)], central layer 3 is formed [referring to 2 (3)] by several plates 3-n alternately with certain longitudinal pitch, spacing between each adjacent plate links to each other the interconnection 31 of mutual group cost heating floor with corresponding one by one the coincideing of each lateral trench 21 of its top backing plate 2; Base plate 4 forms [referring to 2 (4)] by several stripe board 4-n alternately with certain horizontal spacing, and the spacing between each stripe board forms vertical passage 41, and it intersects in length and breadth with the interconnection 21 of the central layer 3 of its top and communicates, and forms netted passage (see figure 3).

From Fig. 3 as seen, each stripe board 4-n of base plate 4 and each plate 3-n of central layer 3 are crisscross, and each vertical passage 41 and interconnection 31 crisscross communicating are netted passage.

The horizontal section structure on Fig. 1 (1) presentation graphs 1 floor, from visible compound four laminate materials, 1,2,3,4 section shapes mutually of this figure, the edge of the left and right sides of Fig. 1 (1) (being the transverse ends on Fig. 1 floor) is processed into concavo-convex alternate tenon e and groove f, the edge at vertical two ends on this floor also is provided with same tenon, groove structure, is convenient to peg graft between the adjacent floor piece together mutually.

The specific embodiment

In this heating floor, panel 1 is the lignum vitae thin plate, and backing plate 2, central layer 3 and base plate 4 can be with the timber of softers such as pine or China fir.

The following steps manufacturing can be adopted in this floor:

Earlier with backing plate 3 with as the sheet material of central layer 3 (can by several sections independently sheet material form) be bonded into one, bonding firmly back is offered interconnection 31 with special-purpose machinery to central layer, passage can reach the downside (being groove 21) of backing plate 2 deeply, and the central layer 3 that links to each other with backing plate 2 bondings is slit into some small plate 3-n simultaneously.

Then will be bonding as the whole sheet material and the above-mentioned central layer surface of base plate 4, bonding firmly back is offered vertical passage 41 with special-purpose machinery to base plate 4, make this vertical passage 41 and above-mentioned interconnection 31 crisscross communicating, simultaneously, the base plate 3 that links to each other with central layer 3 bondings is slit into some stripe board 4-n.

After above technology was finished, plate body placed stress release under the constant temperature, then with panel 1 compoiste adhering on the surface of backing plate 2, make four layers of composite plate.

Last needed tenon e, the groove f of being cut in the edge of above-mentioned composite plate.
