Abstract
Description
Technical Field
[0001] This utility model relates to the field of floor installation technology, and in particular to a wooden floor and its connectors. Background Technology
[0002] Existing wooden flooring strips are typically laid indoors. Each strip has tongue and groove joints on both sides along its longitudinal direction, which are then joined together to form a smooth and flat floor surface. However, outdoors, such as in recreational areas like courtyards, where the ground is uneven, a wooden joist must first be erected to create a flat surface before the wooden flooring strips are nailed onto the joist frame. Grooves should be left between the wooden flooring strips to prevent water accumulation or deformation due to thermal expansion and contraction.
[0003] However, after the above design, the gaps between the wooden floor strips are easily filled with mud and sand, which leads to a decrease in drainage performance. At the same time, the mud and sand and impurities transmit the force of thermal expansion and contraction to the wooden floor strips on both sides, which will still cause the wooden floor strips to deform.

[0052] Please see Figure 1-6 This utility model provides a technical solution: a wooden floor connector, comprising:
[0053] The main body 4 of the strip connector includes:
[0054] The cavity drainage baffle 41 has its inlet end located at the top and its outlet ends located at the bottom on both sides. The cavity drainage baffle 41 fills the space between the strip-shaped wooden floor body 2 on both sides, and the upper surface of the cavity drainage baffle 41 is on the same plane as the upper surface of the strip-shaped wooden floor body 2. Water enters from the inlet end at the top of the cavity drainage baffle 41 and is discharged from the outlet ends at the bottom on both sides.
[0055] A metal filter screen is fixedly installed inside the liquid inlet end above the cavity drainage baffle 41. The metal filter screen can reduce the amount of mud and impurities entering the cavity drainage baffle 41. The impurities entering the cavity drainage baffle 41 are periodically cleaned from the liquid outlets on both sides below the cavity drainage baffle 41. The cleaning method can be spray rinsing.
[0056] The lower edges of the front and rear side walls of the cavity drainage baffle 41 are integrally formed with strip-shaped horizontal plates 42;
[0057] The front and rear side walls of the cavity drainage baffle 41 are uniformly fixed with wedges 43 along the length direction;
[0058] Countersunk screws 44 are evenly inserted along the length of the strip-shaped horizontal plate 42;

[0069] Elastic rubber strips 412 are attached and fixed at the front and rear opening edges of the cavity partition body 411. The elastic rubber strips 412 are elastic elements that undergo elastic deformation after being subjected to force.
[0070] Furthermore, the outer end of the elastic rubber strip 412 is bonded and fixed to the inner edge of the strip cover plate 413 on the same side;
[0071] The wedge 43 is uniformly fixed to the outer side of the strip cover plate 413 along the length direction.

[0077] The strip-shaped horizontal plates 42 on both sides of the strip connector body 4 are respectively inserted into the connecting grooves 3 of the adjacent strip-shaped wooden floor body 2, and a gap is left between the outer end of the strip-shaped horizontal plate 42 and the inner wall of the corresponding connecting groove 3 away from the cavity drainage partition 41.
[0078] The wedges 43 on both sides of the strip connector body 4 are inserted and snapped into the side wall of the strip wooden floor body 2 on the same side.
[0079] In some embodiments, in order to lock and limit the left and right positions of the strip-shaped wooden floor body 2 on both sides by the locking of the wedge 43 and the metal slot 22, the front and rear side walls of the strip-shaped wooden floor body 2 are provided with mounting slots 21 corresponding to the wedge 43 of the adjacent strip-shaped connector body 4.
[0080] Metal slots 22 are glued and fixed inside the mounting slot 21, and the wedges 43 of the strip connector body 4 are inserted and snapped into the corresponding metal slots 22.
[0081] In some embodiments, in order to ensure the strength of the engagement between the wedge 43 and the metal slot 22, the inner cavity of the metal slot 22 is triangular, and the shape of the wedge 43 is triangular to match the inner cavity of the metal slot 22.
[0082] In some embodiments, to enhance the waterproof performance of the strip-shaped wooden floor body 2, the surface of the strip-shaped wooden floor body 2 is coated with a waterproof coating 5.
[0083] In some embodiments, in order to fill the gap between the outer end of the strip horizontal plate 42 and the inner wall of the connecting groove 3 by the rubber layer 6 to avoid the cavity problem, and at the same time, the rubber layer 6 can expand and contract with the elastic structure to cope with the thermal expansion and contraction between adjacent strip wooden floor bodies 2, the outer end of the strip horizontal plate 42 is glued and fixed with the rubber layer 6 and the rubber layer 6 is in contact with the inner wall of the corresponding connecting groove 3.
[0084] In some embodiments, in order to fill the connecting groove 3 of the edge strip wooden floor body 2 and avoid the problem of edge cavity in the wooden flooring, a filling plate 7 is inserted into the connecting groove 3 of the edge strip wooden floor body 2.
[0085] Working principle:
[0086] The strip-shaped wooden floor body 2 is laid horizontally and evenly on the joists 1. The strip-shaped horizontal plate 42 of the strip connector body 4 is horizontally fixed to the upper end of the joists 1 by countersunk screws 44. The front and rear edges of the bottom of the strip-shaped wooden floor body 2 are provided with connecting grooves 3. The strip-shaped horizontal plates 42 on both sides of the strip connector body 4 are respectively inserted into the connecting grooves 3 of the adjacent strip-shaped wooden floor body 2. The wedges 43 on both sides of the strip connector body 4 are inserted and locked into the side wall of the strip-shaped wooden floor body 2 on the same side. The cavity drainage baffle 41 of the strip connector body 4 fills the gap between the adjacent strip-shaped wooden floor bodies 2.
[0087] The upper surface of the cavity drainage baffle 41 is on the same plane as the upper surface of the strip-shaped wooden floor body 2. Water enters from the liquid inlet at the top of the cavity drainage baffle 41 and exits from the liquid outlets at the bottom on both sides. A metal filter screen is fixedly installed inside the liquid inlet at the top of the cavity drainage baffle 41. The metal filter screen can reduce the amount of mud and impurities entering the cavity drainage baffle 41. Impurities entering the cavity drainage baffle 41 are periodically cleaned from the liquid outlets at the bottom on both sides of the cavity drainage baffle 41. The cleaning method can be spray rinsing. Both the front and rear ends of the cavity drainage baffle 41 are elastic structures. The elastic structure deforms with the force of thermal expansion and contraction of the wooden floor strips on both sides. The pressure will not be applied to the wooden floor strips on both sides, thus avoiding deformation of the wooden floor strips.
