Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Example 1: referring to fig. 1 and 2, the pure plane solid wood flooring includes a floor board body 100, and a locking structure 200 disposed on four sides of the floor board body 100, wherein the locking structure 200 includes a male tongue component and a female tongue component formed by milling. When the floor block body 100 is rectangular, the tongue member includes a long-side tongue disposed on the long side of the floor block body 100 and a short-side tongue disposed on the short side of the floor block body 100, and the long-side tongue and the short-side tongue are respectively located on the two tongue side surfaces 120 of the floor block body 100; the female tenon part comprises a long-side female tenon arranged on the long side of the floor block body 100 and a short-side female tenon arranged on the short side of the floor block body 100, and the long-side female tenon and the short-side female tenon are respectively positioned on two female tenon side surfaces 130 of the floor block body 100; the two tongue sides 120 and the two female tongue sides 130 form four sides of the floorboard body 100. In the present embodiment, the surface 110 of the floor board body 100 is directly connected to the two tongue sides 120 and the two tongue sides 130, and both have a right angle included angle of 90 ° with the surface 110; after assembly, the upper edge of the tongue side 120 abuts the upper edge of the box side 130, i.e., there is surface contact between the tongue side 120 and the box side 130.

Borrow by above-mentioned structure, through the structure setting of no chamfer to and the structure setting that the top edge of assembly back tenon side 120 and the top edge of box side 130 leaned on, thereby can avoid assembling and leave the gap between back floor and the floor, and then do benefit to the cleanness and the health on ground, also do benefit to the wholeness and the pleasing to the eye of shop dress face.

Further, the tenon part includes a tenon portion 201, a tenon protrusion 202 disposed on a lower bottom surface of the tenon portion 201, and a tenon root elevation 203, and generally, the tenon root elevation 203 is inwardly closed, so that a protruding length of the tenon portion 201 on the lower bottom surface thereof is greater than a protruding length on an upper surface thereof, and an acute included angle α of 54 to 56 ° (e.g., 55 °) is formed between a locking surface 207 of the tenon protrusion 202 and a longitudinal section of the floor board body 100. The female tenon part comprises a female tenon part 204 in tenon fit with the male tenon part 201, a female tenon concave part 205 arranged on the upper surface of the female tenon part 204 and used for accommodating the male tenon convex part 202, and a female tenon end vertical surface 206. After the tenon is matched, the locking surface 207 is in surface contact fit with the locking surface 208 of the female tenon concave part 205, and the transverse locking of the male tenon part and the female tenon part is realized through the surface contact fit of the locking surface 207 and the locking surface 208. Therefore, the inclination angle of the lock catch surface 207 is set to be 54-56 degrees, and the lock catch surface 207 and the locking surface 208 are in surface contact fit structural arrangement after tenon fit, so that the lock catch surface and the locking surface form self-locking after tenon fit. By utilizing the self-locking of the locking surface 207 and the locking surface 208, the tightness of the tenon matching of the male tenon part and the female tenon part can be improved, thereby effectively avoiding the influence of the size change of the floor board body 100 on the abutting relation between the upper edge of the male tenon side surface 120 and the upper edge of the female tenon side surface 130. For example, when the floor slab body 100 shrinks in size in a geothermal environment, the self-locking of the locking surface 207 and the locking surface 208 can effectively prevent the large expansion gap between the tenon side surface 120 and the mortise side surface 130 due to the locking and unlocking caused by shrinkage tension.

In order to reserve a sufficient expansion gap between two adjacent assembled floor board bodies 100, referring to fig. 3, after the male tongue side surface 120 and the female tongue side surface 130 are matched, an expansion gap of 0.05-0.2 mm is formed between the male tongue part and the female tongue part. Specifically, a telescopic gap l of 0.05 to 0.2mm (e.g., 0.1mm) is formed between the front end surface of the tenon 201 and the bottom surface of the mortise 204₁And is disclosedAn expansion gap l of 0.05-0.2 mm (e.g. 0.1mm) is formed between the tenon root vertical surface 203 and the female tenon end vertical surface 206₂. As will be understood by those of ordinary skill in the art,/₁And l₂The expansion gap values may be the same or different. Meanwhile, the tenon root vertical surface 203 and the bottom surface of the floor block body 100 and the mortise end vertical surface 206 and the bottom surface of the floor block body 100 are in transitional connection through a bottom surface chamfer 140, the bottom surface chamfer 140 and the horizontal plane form an acute included angle of 45 degrees, and the height h of the bottom surface chamfer 140 is 1-2.5 mm (for example, 2.0 mm).

Example 2: the difference between the embodiment 2 and the embodiment 1 is that, referring to fig. 4 and 5, an obtuse included angle beta of 97-103 degrees is formed between the side surface 130 of the female tenon and the surface 110₁When assembled, the pin side 120 and the box side 130 are in surface contact engagement. For example, the obtuse included angle β of 100 ° between the box side 130 and the surface 110₁The side 120 of the tongue forms an acute angle beta of 80 DEG with the surface 110₂. By beta₁And beta₂When the shrinkage of the floor block body 100 is too large, the gap between the tenon side 120 and the mortise side 130 can be visually eliminated to a certain extent by the surface fit of the inclined surfaces therebetween. Furthermore, as is well known to those skilled in the art, in order to smoothly assemble the tongue member into the groove member, the upper top surface of the groove portion 204 is inclined, and when the groove side 130 and the surface 110 form an obtuse included angle β of 97-103 degrees₁In this case, the side surface 130 of the mortise and tenon portion 204 and the top surface of the mortise and tenon portion 204 are formed at an angle close to vertical, thereby improving the structural strength of the portion formed by the surface 110, the side surface 130 of the mortise and tenon portion 204 and the top surface of the mortise and tenon portion.

Example 3: the difference between the embodiment 3 and the embodiment 1 is that, referring to fig. 6 and 7, an obtuse included angle beta of 97-103 degrees is formed between the side surface 130 of the female tenon and the surface 110₃After assembly, an acute included angle gamma of 1-3 degrees is formed between the side surface 120 of the male tenon and the side surface 130 of the female tenon. For example, the dovetail side 130 may have an obtuse included angle β of 98 ° with the surface 110₃The side 120 of the tongue forms an acute angle beta of 80 DEG with the surface 110₄FromAfter assembly, the upper edges of the tongue side 120 and the groove side 130 abut against each other, and an acute included angle γ of 2 ° is formed between the tongue side 120 and the groove side 130. Therefore, compared with the technical scheme of the embodiment 2, the installation noise caused by the surface contact between the tenon side surface 120 and the mortise side surface 130 can be effectively avoided.

Example 4: the difference between the embodiment 4 and the embodiments 1 to 3 is that, referring to fig. 8 and 9, a balance groove 300 is formed between the tongue side surface 120 and the tongue portion 201, and the balance groove 300 is formed to penetrate the length direction of the floor board body 100. The opening depth of the balance groove 300 is 5-10 mm, and the opening width is 0.2-0.3 mm. Through the arrangement of the balance groove 300, cutting is formed between the tenon side surface 120 and the tenon part 201 to a certain extent, so that the dry shrinkage, wet expansion and change rule of the solid wood material comprehensive single board and the solid wood material in the thickness area of the floor block body 100 where the tenon side surface 120 is located is realized, that is, the dry shrinkage, wet expansion and contraction rate of the solid wood material in the thickness area of the floor block body where the tenon side surface 120 is located is reduced.

Example 5: the pure plane solid wood flooring of examples 1-4 was produced by the following machining steps:

s1, four-side polishing, namely performing four-side polishing on the upper surface, the lower surface and two side surfaces of the blank for manufacturing the pure-plane solid wood floor by using a four-side planer;

s2, a primer process, namely sanding the selected front surface and coating a plurality of primer paints (for example, 6 to 8 primer paints);

s3, a lock catch processing procedure, namely manufacturing a lock catch structure 200 on the periphery of the intermediate material coated with the primer;

s4, a finishing process, namely, performing multiple (for example, 2-4) finishing paint passes on the coated primer;

and S5, coating edge sealing paint or coating liquid and wax on the periphery of the lock catch structure 200.

Example 6: the pure plane solid wood floors of examples 1-4 can also be produced by the following machining steps:

step S2, a primer and finish procedure, sanding the selected front surface, and coating a plurality of primer paints (for example, 6 to 8 channels) and a plurality of finish paints (for example, 2 to 4 channels);

and S4, coating edge sealing paint or coating liquid and wax on the periphery of the lock catch structure 200.

In the embodiments 5 and 6, the mirror frame effect formed by painting on the surface of the pure plane solid wood floor is effectively avoided through the steps of painting first (only painting primer or complete painting) and then locking and buckling.

Example 7: the blank used to make the solid wood flooring may also be waxed prior to the machining steps of examples 5, 6. Wherein, the wax injection step comprises the following stages in sequence:

s1 and a quick drying stage, wherein the treated material with the initial water content of 60-65% is placed in a wax liquid at 75-80 ℃ for treatment for 16-26 h until the water content of the treated material is reduced to 30-35%;

s2 and an intermediate drying stage, namely heating the wax liquid to 85-90 ℃ at a heating rate of 2.8-3.2 ℃/h, and preserving heat for 12-18 h after the temperature reaches a set temperature until the water content of the treated material is reduced to 15-20%;

and S3 stage and wax injection stage, wherein the treated material is treated in wax liquid at 100-110 ℃ for 2-16 h, the vacuum degree in a wax injection container is set to be 0.06-0.07 MPa, and cold water is continuously introduced into the top of the wax injection container in the whole wax injection stage.

In this embodiment, before the S1 stage, referring to fig. 10, the processed material 400 is stacked layer by layer, and the processed materials 400 of adjacent layers are spaced apart from each other by the spacer 500. The interval between adjacent parting strips 500 is 30 ~ 40cm, and two parting strips 500 of head and the tail are located the head end and the end of being handled material 300 length direction respectively. After the stacked processed timber piles are fastened in three directions (the upper surface and the lower surface of the timber piles can be fastened with one side surface by adopting any stacking frame in the prior art), the timber piles are overturned by 90 degrees and then are hoisted into a wax injection container. Thus, referring to fig. 11, the material 400 to be processed is horizontally placed in the longitudinal direction of the wax injection container, that is, the material 400 to be processed is horizontally placed in the liquid surface of the wax liquid in the longitudinal direction and is vertically placed in the wax liquid. Preferably, as shown with reference to FIG. 12, the division bar 500 has an "H" shape in cross section.

In the embodiment, the continuous introduction of cold water into the top of the wax injection container is realized by arranging a cold water pipe on the top of the wax injection container in a coiled mode. The cold water pipe can be connected with a cold water source and also can be connected with a water outlet of the heat pump machine. That is, the water vapor discharged from the wax injection container after drying the material to be treated passes through the heat pump unit, and the heat is recovered by the heat pump unit and used for heating the apparatus, condensed into condensed water, and introduced into the cold water pipe.

In this embodiment, the processed material 400 with a relatively high initial water content is placed in the high-temperature wax liquid in the rapid drying stage, at this time, in the wax liquid with a relatively high temperature, a large amount of moisture in the processed material 400 is discharged rapidly, so that a certain degree of sealing effect is formed on the surface of the processed material 400 by using the speed of water migration discharge in the processed material 400 and the speed difference of water dissolution and replacement in the wax liquid, a replacement channel between the moisture in the processed material 400 and the wax liquid is increased, the impregnation rate and the impregnation depth of the wax liquid are improved, and therefore it is ensured that the pure-plane solid wood floor after wax liquid impregnation hardly undergoes shrinkage and wet expansion in the use process. Meanwhile, by increasing the replacement passage of the water and the wax liquid inside the material 400 to be processed, the processing temperature and the processing time in the S3 stage (wax injection stage) can be effectively reduced, thereby avoiding the excessive carbonization of the material to be processed caused by the excessively high wax injection processing temperature and the excessively long wax injection processing time and affecting the color of the material.

Example 8: the blank used to make the solid wood flooring may also be waxed prior to the machining steps of examples 5, 6. Wherein, the wax injection step comprises the following stages in sequence:

the step S3 and the step S of shaking and drying, namely heating the wax liquid to 100-110 ℃ at a heating rate of 1.5-2.0 ℃/h, stopping heating for 10-20 min every 1-1.5 h (stopping heating for 15min every 1.5h in the embodiment) in the heating process, stopping heating for 2-4 times (stopping heating for 3 times in the embodiment), and continuously introducing cold water into the top of a wax injection container in the whole shaking and drying stage;

and S4 stage and wax injection stage, wherein the treated material is treated in wax liquid at 100-110 ℃ for 2-16 h, the vacuum degree in a wax injection container is set to be 0.06-0.07 MPa, and cold water is continuously introduced into the top of the wax injection container in the whole wax injection stage.

In this embodiment, the heating is stopped (oscillation drying) 2 to 4 times in the oscillation drying stage to repeatedly form a temperature gradient of high inside and low outside and a water content gradient of high outside and low inside the material to be processed 400, so that the displacement of water and wax, that is, the discharge of water and the dipping of the wax liquid can be effectively promoted, and the dipping rate and the dipping depth of the wax liquid can be increased. Meanwhile, the processing temperature and the processing time in the S4 stage (wax injection stage) can be effectively reduced, so that excessive carbonization of the processed material and influence on the material color of the processed material caused by the excessively high wax injection processing temperature and the excessively long wax injection processing time are avoided. In addition, the pure-plane solid wood floor blank prepared by the wax injection method of the embodiment has relatively high final water content, so that the pure-plane solid wood floor blank can relatively well adapt to regional environments with large annual humidity span.
