Description

Technical Field

[0001] The utility model belongs to the technical field of wooden floor construction, in particular to a solid wooden floor keel fixing structure. Background Art

[0002] The floor keel bracket is a bracket used for installing wooden floors. It consists of an upper frame and a lower frame. The keel bracket is a building material used to support the shape and fix the structure. It is used as the skeleton and base material of the building decoration structure. It has good supporting effect and low production cost. It is widely used in various decoration and construction fields.

[0003] Usually, the keels are installed on the ground by independent strip brackets. They need to be leveled before being fixed. Adjusting each individual keel requires high construction precision and technical level, which increases the construction difficulty and cost. The connection and support relationship between the keels may change during the adjustment process, resulting in a decrease in the stability of the overall structure. Therefore, we proposed a wooden floor keel fixing structure. Utility Model Content

[0004] The purpose of the utility model is to provide a solid wood floor keel fixing structure. By setting a leveling component and adjusting the horizontality of the frame, the unevenness of the ground can be compensated, so that the floor will be more flat and beautiful after laying. The base can not only be used to adjust the horizontality, but also serve as a supporting frame, solving the problem that the existing adjustment of each individual keel requires high construction precision and technical level, which increases the construction difficulty and cost, and the connection and support relationship between the keels may change during the adjustment process, resulting in a decrease in the stability of the overall structure.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a solid wood floor keel fixing structure, comprising a frame, wherein the front and back sides of the frame are provided with slide grooves, a keel is provided inside the frame, the front and back sides of the keel are slidably connected to the inner wall of the slide groove, and the four corners of the frame are provided with adjustment holes. The keels can be freely slid and adjusted inside the frame, and the spacing between the keels can be flexibly adjusted according to actual needs. In areas with greater stress, the spacing between the keels can be appropriately reduced to ensure the stability and durability of the wood floor, while in areas with less stress, the spacing between the keels can be appropriately increased to reduce material waste and construction costs.

[0007] A leveling assembly is provided inside the four adjustment holes, and the leveling assembly includes a screw rotatably connected to the inner wall of the adjustment hole, a cross slot is provided on the top of the screw, and a base is provided at the bottom of the frame, the inner wall of the base is threadedly connected to the outer surface of the screw, and the side of the base close to the frame is fixedly connected to the limit rod, and the four corners of the frame are provided with circular holes, and the inner wall of the circular hole is slidably connected to the outer surface of the limit rod to adjust the lifting of the base. The lifting of the base adjusts the height of the four corners of the frame. By adjusting the levelness of the frame, the unevenness of the ground can be compensated, making the floor more flat and beautiful after laying.

[0008] Furthermore, the tops of several of the keels are flush with the top of the frame, and the tops of several of the keels are each provided with adjustment holes 2. The tops of the keels are flush with the tops of the frame to ensure overall flatness, making the wooden floor more flat when laid.

[0009] Furthermore, a support assembly is provided inside several of the adjustment holes 2, and the support assembly includes a bolt rotatably connected to the inner wall of the adjustment hole 2. A cross slot is also provided on the top of the bolt, and the head design of the cross slot bolt makes it more convenient to rotate the bolt.

[0010] Furthermore, square grooves are opened inside several of the keels, and the inner walls of several of the square grooves are slidably connected with support blocks, which provide stable support points for the keels, ensuring that the keels will not shake or move due to external forces after horizontal adjustment.

[0011] Furthermore, a threaded hole is opened at the center of several of the support blocks, and the outer surface of the bolt is threadedly connected to the inner wall of the threaded hole. The bolt is rotated clockwise using a tool, and the rotation of the bolt drives the support block to move toward the ground. Depending on the different distances between each keel and the bottom surface, the moving distance of the support block is also different.

[0012] Furthermore, several of the support blocks are provided with mounting holes on their bottoms and side walls, and the top level of the bolts is lower than the top of the keel. The installers use nails to fix the support blocks to the ground through the mounting holes. The side walls of the support blocks are also provided with mounting holes, and the support blocks can also be fixed to the keel using nails and other fixing parts.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a leveling component. Specifically, the installer uses a tool to turn the screw. As the screw turns, the base is adjusted to rise and fall. The rise and fall of the base adjusts the height of the four corners of the frame. The horizontality of the frame is adjusted to make up for the unevenness of the ground, making the floor more flat and beautiful after laying. The base can not only be used to adjust the levelness, but also serve as a support frame.

[0015] 2. The utility model sets a support assembly, specifically uses a tool to rotate the bolt clockwise, and as the bolt rotates, the support block is driven to move toward the ground. After the support block is moved to contact the ground, the installer uses nails to fix the support block to the ground through the mounting holes. The side walls of the support block are also provided with mounting holes, and the support block and the keel can also be fixedly connected with nails and other fixing parts. The support block provides a stable support point for the keel, ensuring that the keel will not shake or displace due to external force after horizontal adjustment, and preventing the keel from collapsing after the wooden floor is laid.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 As shown, the present invention is a solid wood floor keel fixing structure, comprising a frame 1, wherein opposite sides of the frame 1 are provided with slide grooves 102, a keel 101 is provided inside the frame 1, and the front and back surfaces of the keel 101 are slidably connected to the inner wall of the slide groove 102, and the four corners of the frame 1 are provided with adjustment holes 103;

[0027] The four adjustment holes 103 are each provided with a leveling assembly 2, which includes a screw 202 rotatably connected to the inner wall of the adjustment hole 103. The top of the screw 202 is provided with a cross slot 201. The bottom of the frame 1 is provided with a base 203. The inner wall of the base 203 is threadedly connected to the outer surface of the screw 202. The side of the base 203 close to the frame 1 is fixedly connected to the limit rod 204. The four corners of the frame 1 are provided with a circular hole 205. The inner wall of the circular hole 205 is slidably connected to the outer surface of the limit rod 204. By setting the leveling assembly 2, the installer uses a tool to adjust the screw 202 rotates. Since the screw 202 is installed inside the adjusting hole 103, the top diameter of the adjusting hole 103 is smaller than the diameter of the top of the screw 202. The screw 202 can only rotate on the inner wall of the adjusting hole 103 and cannot move up and down. Therefore, as the screw 202 rotates, the base 203 is adjusted to rise and fall. The rise and fall of the base 203 adjusts the height of the four corners of the frame 1. By adjusting the levelness of the frame 1, the unevenness of the ground can be compensated, making the floor more flat and beautiful after laying. The base 203 can not only be used to adjust the levelness, but also serve as a support for the frame 1.

[0028] The tops of the plurality of keels 101 are arranged horizontally and flush with the top of the frame 1 , and the tops of the plurality of keels 101 are each provided with a second adjustment hole 104 .

[0029] A support assembly 3 is provided inside each of the plurality of second adjustment holes 104 . The support assembly 3 includes a bolt 302 rotatably connected to the inner wall of the second adjustment hole 104 .

[0030] A square groove 105 is formed inside each of the keels 101 , and a support block 301 is slidably connected to the inner wall of each of the square grooves 105 .

[0031] A threaded hole 304 is formed at the center of each of the support blocks 301 , and the outer surface of the bolt 302 is threadedly connected to the inner wall of the threaded hole 304 .

[0032] The bottom and side walls of the support blocks 301 are provided with mounting holes 303, and the top level of the bolt 302 is lower than the top of the keel 101. By setting the support assembly 3, specifically by using a tool to turn the bolt 302 clockwise, the support block 301 is driven to move toward the ground as the bolt 302 rotates. After the support block 301 is moved to contact the ground, the installer uses nails to fix the support block 301 to the ground through the mounting holes 303. The side walls of the support block 301 are also provided with mounting holes 303. Nails and other fixing parts can also be used to fix the support block 301 to the keel 101, thereby enhancing the connection strength between the support block 301 and the keel 101, preventing slippage between the keel 101 and the support block 301, and providing a stable support point for the keel 101, ensuring that the keel 101 will not shake or move due to external force after horizontal adjustment, and preventing the keel 101 from collapsing after laying the wooden floor.

[0033] A specific application of this embodiment is: placing the frame 1 on a planned ground, using a leveling instrument to measure the level of the frame 1, and the installer using a tool to rotate the screw 202. As the screw 202 rotates, the base 203 is adjusted to rise and fall. The limit rod 204 connected to the base 203 slides on the inner wall of the circular hole 205. The limit rod 204 ensures that the base 203 can only move up and down and cannot rotate. By adjusting the rise and fall of the base 203, the height of the four corners of the frame 1 can be adjusted. By adjusting the levelness of the frame 1, the unevenness of the ground can be compensated, making the floor more flat and beautiful after laying. The base 203 can not only be used to adjust the levelness, but also serve as a support for the frame 1.

[0034] A plurality of keels 101 are provided inside the frame 1. The keels 101 can be freely slid and adjusted inside the frame 1. The spacing between the keels 101 can be flexibly adjusted according to actual needs. In areas with greater stress, the spacing between the keels 101 can be appropriately reduced to ensure the stability and durability of the wooden floor. In areas with less stress, the spacing between the keels 101 can be appropriately increased to reduce material waste and construction costs. After determining the position of the keel 101, since there is a gap between the keel 101 and the ground after the corners of the frame 1 are adjusted to be level, the bolt 302 is turned clockwise with a tool. As the bolt 302 rotates, the support block 301 is driven to move toward the ground, and the support block 301 is moved to the ground. After moving to contact with the ground, the installer uses nails to fix the support block 301 to the ground through the mounting holes 303. The side walls of the support block 301 are also provided with mounting holes 303. Nails and other fixing parts can also be used to fix the support block 301 to the keel 101. At this time, the keel 101 is fixed by the support block 301. The support block 301 provides a stable support point for the keel 101, ensuring that the keel 101 will not shake or shift due to external force after horizontal adjustment, and prevents the keel 101 from collapsing after laying the wooden floor. In a humid environment, the support block can prevent ground moisture or water from eroding the keel, thereby playing a moisture-proof role.
