Description

Solid wood flooring for fast, non-destructive, warp-resistant installation

technical field

The utility model relates to a solid wood floor used for fast, non-destructive and warp-proof installation.

Background technique

The structures of most of the existing solid wood floors are that the two lateral sides of the floor and the two longitudinal end faces of the floor are respectively provided with mutually matching flat tenons and flat grooves. When paving, first fix the floor with the wooden keel pre-fixed on the ground with inclined floor nails, and then connect the two floor boards through the flat tenons and flat grooves. This pavement method has the following problems in actual operation: 1. Since several floor nails pass through the floor obliquely and then extend into the keel, the floor nails form a lateral extrusion force on the floor. If the extrusion force is too large, the side edges of the floor will be arched. Therefore, the surface of the paved wooden floor will be uneven, forming a phenomenon that the joints of adjacent floors are higher and the middle of the floor is lower. 2. Since the floor nails are inclined downward to fix the floor boards, and the position of the floor nails nailed into the floor boards and the keel is manually mastered by the paving personnel based on experience, the tightness of the contact between the floors is not easy to grasp, resulting in pre-set joints at the joints. The gaps are uneven, and after experiencing a humid or dry climate, the floor is prone to deformation such as arching or depression caused by inconsistent size changes between the upper and lower surfaces. 3. After the installation is completed, if there is a color difference between the floors or other quality problems are found during use and the floor needs to be replaced, the floor nails must be pulled out, which will inevitably damage the floor at the nails and cause waste. 4. It takes a long time to install the floor and the efficiency is low.

Utility model content

The purpose of this utility model is to provide a solid wood floor for fast non-destructive and anti-warping installation. Using the solid wood floor can quickly complete the laying of the floor; the installation will not damage the solid wood floor, and the floor can be reused after removal; and after installation The floor can effectively avoid upward or downward warping.

The solid wood floor for fast, non-destructive and anti-warping installation is provided with mutually matching tongue-shaped tenons and tongue-shaped grooves on the two lateral sides of the floor, respectively, and the tongue-shaped tenons and tongue-shaped grooves are respectively provided with matching protrusions and recesses. When the tongue-shaped tenon and the tongue-shaped groove of two adjacent floors are matched, the protruding part extends into the concave part to limit the translation of one floor relative to the other in the transverse direction and the warping in the direction perpendicular to the floor surface. curved; on the two longitudinal end faces of the floor, there are respectively provided with flat tenons and flat grooves which cooperate with each other; on the back of the floor, grooves are respectively arranged near the two ends.

When the above-mentioned solid wood floor is installed, the following steps are included: in the longitudinal direction, match the flat tenon of one solid wood floor with the flat groove of the other solid wood floor; extend the two ends of an elastic clip into the vertically adjacent grooves of the two solid wood floors respectively Inside, use the elastic force of the elastic clip to connect the two solid wood floors vertically; in the horizontal direction, match the tongue-shaped tenon of one solid wood floor with the tongue-shaped groove of the other solid wood floor. The elastic clip is preferably in a "U" shape. Preferably, there is a protruding rib in the middle of the bottom of the elastic clip to increase its elasticity.

Cooperate the tongue-shaped tenon and the tongue-shaped groove of two adjacent floorboards, and the protruding part extends into the concave part, which limits the translation of one floorboard relative to the other floorboard in the direction perpendicular to the side with the tongue-shaped tenon (horizontal direction). The tongue-shaped tenon extends into the tongue-shaped groove, and the tongue-shaped groove limits the displacement of the tongue-shaped tenon in the direction perpendicular to the floor surface, so it can effectively prevent the floor from warping in the direction perpendicular to the floor surface. The spring clips limit the longitudinal translation of one floor relative to the other. In the longitudinal direction, matching the flat tenon of one solid wood floor with the flat groove of another solid wood floor can prevent the floor from warping laterally. The installation does not require floor nails to be nailed into the floor, and will not damage the floor; it will not cause lateral force to the floor, and the floor is relatively flat. The gap between the floors is guaranteed by the processing quality of the floor, not by hand, so the gap is even. The installation is time-saving and labor-saving, fast and efficient. When dismantling, just remove the elastic clip, the floor will not be damaged, and the floor can be reused.

The specific shapes and structures of the tongue-shaped tenon and tongue-shaped groove can be varied. For example, the tongue-shaped tenon is located in the middle of the side, and the lower part of the tongue-shaped tenon has a zigzag protrusion; of course, corresponding to the tongue-shaped tenon, the lower part of the tongue-shaped groove has a Zigzag indentation. As a preferred shape and structure of the tongue-shaped tenon and tongue-shaped groove, the tongue-shaped tenon is located in the middle of the side, the front end of the tongue-shaped tenon has a downward arc-shaped protrusion, and the rear end of the tongue-shaped tenon has an upward concave portion; Corresponding to the tenon, the front end of the tongue-shaped groove has a downward arc-shaped recess corresponding to the arc-shaped protrusion of the tongue-shaped tenon, and the rear end of the tongue-shaped groove has an upward protrusion corresponding to the concave portion of the tongue-shaped tenon.

Detailed ways

Example 1

Referring to the solid wood floor for quick and non-destructive anti-warping installation shown in Fig. Arc tongue groove 5. The tongue-shaped tenon 4 protrudes outward along the middle part of the side surface 2 ; its front end has a downward arc-shaped protrusion 6 , and its rear end has an upward concave portion 8 .

The tongue-shaped groove 5 corresponding to the tongue-shaped tenon 4 is recessed inwardly along the middle part of the side surface 3 ; its front end has a downward arc-shaped concave portion 9 , and its rear end has an upward protrusion 7 .

On the two opposite end surfaces 12 and 13 in the length direction (longitudinal direction) of the floor, there are provided flat tenons 14 and flat grooves 15 which cooperate with each other. The flat tenon 14 protrudes outward along the middle part of the end face 12 ; the flat groove 15 is recessed inward along the middle part of the end face 13 . Grooves 16 , 17 are provided on the floor back surface 10 near the floor end surfaces 12 , 13 respectively.

Referring to Fig. 3-5, when the above-mentioned solid wood floor is installed and laid, the wooden keel is fixed on the ground. tenon joint. Then use the two ends of the steel elastic clip 18 of " U " shape to stretch respectively in the vertically adjacent grooves 16 , 17 of the two solid wood floors, and connect the two solid wood floors longitudinally with the elastic force of the elastic clip, limiting the The longitudinal translation of one floor relative to another. When the flat tenon and flat groove are matched, it can prevent the floor from warping laterally. Then in the horizontal direction (the floor width direction), the arc-shaped tongue-shaped tenon 4 of a piece of solid wood floor is matched with the arc-shaped tongue-shaped groove 5 of another piece of solid wood floor for tenon joint. During the tenon joint, the arc-shaped protrusion 6 cooperates with the arc-shaped recess 9 , and the protrusion 7 cooperates with the recess 8 . Cooperating projections and recesses limit translation of one floorboard relative to the other in a direction perpendicular to the side of the floorboards having the tongue (transversely). The tongue-shaped tenon 4 extends into the tongue-shaped groove 5, and the tongue-shaped groove limits the displacement of the tongue-shaped tenon in the direction perpendicular to the floor surface, so it can effectively prevent the floor from warping in the direction perpendicular to the floor surface. In this way, the adjacent solid wood floors are connected to each other in the horizontal direction, the vertical direction and the direction perpendicular to the floor surface and float on the wooden keel. There are protruding ribs 19 in the middle of the bottom of the elastic clip to increase its elasticity.

The installation of this floor will not damage the notch (tongue-shaped tenon, tongue-shaped groove, flat tenon, flat groove) of the solid wood floor, and the floor can be reused after removal; the notch structure of the floor has the effect of restricting the floor from moving up and down The installed floor can effectively avoid warping upwards or downwards.

When the floor of this embodiment is installed and laid, it can ensure that there is no gap between the finally installed floor and the wall. This is not possible in the existing floor that is provided with mutually matching flat tenons and flat grooves on the two lateral sides of the floor and the two longitudinal end faces of the floor respectively.

Example 2

Referring to the solid wood floor for quick and non-destructive anti-warping installation shown in FIG. 6, tongue-shaped tenons 2 and tongue-shaped grooves 3 that cooperate with each other are provided on two opposite sides in the width direction (horizontal direction) of the floor 1. The tongue-shaped tenon 2 protrudes outward along the middle part of the side; its lower part has a zigzag protrusion 13 . The tongue-shaped groove 3 corresponding to the tongue-shaped tenon 2 is recessed inward along the middle part of the other side; its lower part has a zigzag recessed part 14 . The two opposite end faces in the length direction (longitudinal direction) have the same flat tenons and flat grooves as in Embodiment 1, and the same grooves as in Embodiment 1 are also opened on the back (refer to Figure 2).

Referring to FIG. 6 , when the tongue-shaped tenon 2 of a solid wood floor is matched with the tongue-shaped groove 3 of another solid wood floor for tenon joint in the transverse direction, the protruding part 13 is matched with the concave part 14 . The vertically connected structure is the same as in Embodiment 1 (refer to FIGS. 4 and 5).

Comparing Examples 1 and 2, from the tooth-shaped surface of the tongue-shaped tenon, the tongue-shaped tenon (groove) in embodiment 1 is an arc-shaped tongue-shaped tenon (groove), and the tongue-shaped tenon (groove) in embodiment 2 is Zigzag tongue-shaped tenon (groove), these two kinds of tongue-shaped tenon (groove) have identical function in the utility model, but the floor with zigzag tongue-shaped tenon (groove) has its deficiency in production and installation process. We know that the thickness of the floor is 18mm, and the maximum thickness of the zigzag tenon (groove) is less than 6mm. At the front end of the zigzag tongue (groove), the thickness is even smaller. Because the wood is relatively brittle, the tenon tip is easy to collapse ; and the sawtooth undulation on the zigzag tongue-shaped tenon (groove) is very small, generally less than 0.5mm, and it is difficult to play the role of tightening and preventing falling off when matching between adjacent floors.
