Description

Technical Field

[0001] This utility model relates to the field of wood flooring manufacturing technology, and in particular to a wood flooring with its own joists. Background Technology

[0002] Flooring is a building material used for the surface layer of a house's ground or floor, primarily made of wood or other materials. Wood flooring, in particular, is the most popular choice due to its ease of processing, good elasticity and plasticity, excellent temperature regulation properties, and high strength-to-weight ratio. The joist structure in wood flooring provides advantages such as comfortable foot feel, sound insulation, shock absorption, and resistance to deformation. While a moisture barrier is laid during installation of wood flooring with a joist, and the joist layer creates a channel for air circulation, in reality, workers walking on and dragging tools across the moisture barrier during installation can easily tear or puncture it. Furthermore, lower-quality moisture barriers age over time, losing their functionality. In addition, moisture from the ground, such as in ground-floor apartments, during the humid season in southern regions, and at bathroom entrances, can seep into the joist layer along gaps in walls and baseboards. Simultaneously, the joist layer also absorbs moisture from the air. Furthermore, accidental intrusion of liquid water in daily life, such as pet urine, spilled water, or rainwater entering through windows, makes the joist layer of the wood flooring susceptible to dampness, leading to rot, mold, deformation, warping, and squeaking. Therefore, it is necessary to provide a type of wood flooring with excellent ventilation and moisture-proof properties. Utility Model Content

[0003] The purpose of this invention is to provide a wooden floor with a built-in keel, which has excellent ventilation and moisture-proof performance.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wooden floor with a built-in keel, comprising a floor body and a keel, wherein a dovetail groove is formed on the bottom surface of the floor body, a dovetail tenon is formed on the top of the keel, the dovetail tenon is embedded in the dovetail groove, the bottom surface of the keel protrudes from the bottom surface of the floor body, the keel is provided with a first channel, the two ends of the first channel are formed with mating joints, the side of the first channel is connected to a second channel, and the side wall of the second channel is provided with a through hole.

[0005] By adopting the above technical solution, this utility model uses a dovetail tenon and dovetail groove structure to connect the joists and the flooring body into a whole, eliminating the need for nails and glue during installation. The bottom surface of the joists protrudes from the bottom surface of the flooring body, forming a space between the flooring body and the flooring after installation, namely the joist layer, achieving the effects of moisture resistance and good foot comfort after the wood flooring is installed.

[0006] During the installation of wood flooring, multiple floorboards with their own joists are spliced ​​together to form the entire floor. The joists are also spliced ​​sequentially, and the first channels on the joists are spliced ​​sequentially as well. The joints of adjacent first channels fit tightly together to achieve sequential connection. After multiple first channels are spliced, one end is sealed with a wooden plug or similar material, and the other end is used to connect to an exhaust device. The exhaust device creates negative pressure, causing moisture inside the joist layer to be expelled sequentially through the through holes, second channels, and first channels. Compared to waiting for moisture inside the joist layer to dissipate naturally, this method can quickly and effectively expel moisture, achieving active ventilation and moisture prevention, and reducing corrosion and mold growth on the joists.

[0007] A further feature of this invention is that the four sides of the floor body are provided with latches or snap fasteners for interconnection.

[0008] By adopting the above technical solution, the overall installation is convenient and quick.

[0009] A further feature of this invention is that the floor body is a multi-layer solid wood floor.

[0010] A further feature of this invention is that the keel material is wood, metal, or plastic.

[0011] By adopting the above technical solution, when the keel material is wood, you can choose wood of the same material as the floor body, or you can choose wood of a different material from the floor body.

[0012] A further feature of this invention is that the bottom surface of the keel protrudes from the bottom surface of the floor by a distance greater than 1 mm.

[0013] A further feature of this invention is that the number of keels is multiple, and the spacing between the keels along the length of the floor body is 200-600 mm.

[0014] A further feature of this invention is that the depth of the dovetail groove is 5-40 mm, and the length of the dovetail groove is less than or equal to the width of the floor body.

[0015] A further feature of this invention is that the bottom surface of the floor body is provided with multiple back grooves, the back grooves are opened along the length direction of the floor body, the depth of the back grooves is 3-15 mm, and the spacing between the back grooves is 20-100 mm.

[0016] By adopting the above technical solution, the purpose of creating the back groove is to prevent the floor itself from deforming.

[0017] A further feature of this invention is that the second channel is made of flexible tubing, the number of keels is at least two, each keel has a groove on both sides, a movable member is provided between two adjacent keels, a slider is provided on the side of the movable member, the slider is located in the groove, a mounting base and a stop are fixed on the side wall of the keel, a return spring is installed between the mounting base and the movable member, the return spring acts on the movable member to press the second channel against the stop, and an adjustment line is fixed on the side of the movable member away from the return spring.

[0018] By employing the aforementioned technical solution, the space within the joist layer is not completely sealed. Over time, dust and debris from the house will gradually accumulate within the joist layer. This dust may also contain dust mites, mold spores, pet dander, and other contaminants. When people walk, sweep, or vacuum on the wooden floor, the resulting airflow disturbances can cause dust to re-enter the indoor air through the floor gaps, posing a health threat. Furthermore, the debris accumulated in the joist layer becomes a food source for pests. However, opening the floor for cleaning would damage the floor structure, making restoration difficult and costly.

[0019] Based on this, this utility model utilizes an exhaust device, a first channel, and a second channel to extract moisture from the keel layer, and can also extract dust and debris accumulated within the keel layer. Since multiple first channels are sequentially connected to form a single integrated channel, and this integrated channel simultaneously connects to multiple second channels, if all second channels are extracted simultaneously, the suction force at the through-hole of each second channel will be relatively weak, resulting in limited effectiveness in extracting dust and debris. Although equipping a high-powered suction device could solve the above problems, issues related to cost, size, and transportation make it impractical.

[0020] This invention features a structure with a return spring and adjusting lines. In the non-suction state, the return spring acts on the movable part, and the second channel, connected to the movable part, is made of flexible tubing and is pressed against the stop block, thus being in a blocked state. With the suction device running, the operator pulls the first adjusting line, causing the movable part and the second channel to move, opening the second channel and allowing the suction of moisture, debris, and dust from the keel layer. The movement of the movable part also expands the suction range of the second channel. When the operator releases the first adjusting line, the return spring causes the movable part and the second channel to reset, and the second channel is once again pressed against the stop block, remaining blocked. The operator then pulls the second adjusting line, repeating this process multiple times to complete the suction of dust and debris.

[0021] The present invention is further configured such that: the keel is provided with multiple guide rings, and the adjustment line passes through the guide rings; the reset spring is made of plastic; the number of floor bodies is multiple and they are spliced ​​together in sequence, the keels on the bottom surfaces of the multiple floor bodies are connected in sequence, the floor body located at the outermost edge has a through hole, and the first channel of the keel on the bottom surface of the outermost floor body is connected to a flexible hose, and the through hole allows the adjustment line and the flexible hose to pass through.

[0022] By adopting the above technical solution, the guide ring is used to guide and limit the adjustment line. The return spring is made of plastic, not metal, to avoid rusting.

[0023] The beneficial effects of this utility model are as follows: This utility model adopts a dovetail groove and dovetail tenon structure to connect the joists and the floor body into a whole. It eliminates the need for nails and glue during installation. The bottom surface of the joists protrudes from the bottom surface of the floor body, ensuring that there is a space height between the wood floor and the ground after installation, achieving the purpose of moisture prevention while ensuring the feel of the floor underfoot. The joists improve the stability of the wood floor to a certain extent. The nail-free installation also avoids damage to the pre-buried pipelines when using nails during installation. The wood floor of this utility model is convenient and quick to install. Attached Figure Description
