Description

Technical Field

[0001] This utility model relates to the field of building structure and floor paving support technology, specifically a wooden floor support frame with a splicing structure. Background Technology

[0002] With the popularization of prefabricated buildings and outdoor flooring systems, wood-plastic composite (WPC) flooring is widely used due to its environmental friendliness, corrosion resistance, and ease of maintenance. However, most existing WPC flooring uses a joist and screw fixing method, which is complex to install, makes it difficult to ensure levelness, and is inconvenient to disassemble.

[0003] While some existing floor support structures do have height-adjustable features, they generally suffer from the following drawbacks: 1. Weak support body: Nuts are directly welded to thin-walled square tubes, resulting in insufficient welding area, which can easily lead to cracking or loosening of threads; 2. Lack of modular design: The supports cannot be quickly assembled, resulting in poor overall flatness and construction efficiency; 3. Simple adjustment structure: insufficient support capacity and poor ground adaptability.

[0004] Therefore, a wooden floor support frame with a splicing structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wooden floor support frame with a splicing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wooden floor support frame with a splicing structure, comprising a first bottom frame, a second bottom frame, and a third bottom frame. Heightening welding nuts are fixedly installed on the four outer surfaces of the first, second, and third bottom frames. Adjusting screws are threaded into the interior of each heightening welding nut. Multiple limiting frames are fixedly installed on the first, second, and third bottom frames by welding. A locking plate is slidably installed within the space enclosed by the limiting frames and the first bottom frame. Snap-fit ​​grooves are fixedly installed at corresponding positions on adjacent first, second, and third bottom frames by welding. One end of the locking plate snaps into the corresponding snap-fit ​​groove.

[0007] Preferably, the card plate is U-shaped.

[0008] Preferably, the adjusting screws have various shapes, with one end of the uppermost adjusting screw having a slot, and the other three having internal hexagonal slots, and the other ends of the multiple adjusting screws having bases made of rubber or nylon.

[0009] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model can realize the rapid assembly and disassembly of multiple units by setting a card plate and a card slot on the bracket.

[0010] (2) This utility model can effectively and quickly complete the floor leveling during construction by adjusting the screw to rotate quickly on the heightening welding nut on the bracket.

[0011] (3) In this utility model, by increasing the wall thickness of the square tube to 1.5mm and using the M6 ​​welding nut, the bearing capacity of the support leg is significantly improved, thus avoiding weld failure.

[0012] (4) In this utility model, the base of the adjusting screw is made of rubber or nylon, which has the functions of anti-slip, vibration reduction and ground protection, and extends service life. At the same time, the setting of the slot or internal hexagonal slot at the other end of the adjusting screw makes it convenient for construction personnel to rotate and adjust the adjusting screw with the corresponding tools.

[0013] (5) This utility model can be applied to different indoor and outdoor environments and has good promotional value. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figure 1-6This utility model provides a technical solution: a wooden floor support frame with a splicing structure, including a first base frame 1, a second base frame 2, and a third base frame 3. Heightening welding nuts 4 are fixedly installed on the four outer surfaces of the first base frame 1, the second base frame 2, and the third base frame 3. Adjusting screws 5 are threaded into the interior of each heightening welding nut 4. The adjusting screws 5 have various shapes, with one end of the uppermost adjusting screw 5 having a slot, and the other three having internal hexagonal slots. The other end of each adjusting screw 5 has a base made of rubber or nylon. Multiple limiting brackets 6 are fixedly installed on the first base frame 1, the second base frame 2, and the third base frame 3 by welding. A locking device is slidably installed inside the space enclosed by the limiting brackets 6 and the first base frame 1. The plate 7 is U-shaped. Corresponding slots 8 are welded and fixedly installed at corresponding positions on adjacent first bottom frames 1, second bottom frames 2, and third bottom frames 3. One end of the plate 7 is engaged with the corresponding slot 8. By using various adjusting screws 5 spirally connected to the corresponding heightening welding nuts 4, it not only facilitates support for the assembled first bottom frame 1, but also ensures that the assembled first bottom frame 1 remains horizontal under different ground conditions using a single adjusting screw 5. Simultaneously, the limiting frame 6 restricts the position of the plate 7. The corresponding arrangement of the plate 7 and the slots 8 allows for convenient splicing and interlocking of the two first bottom frames 1, preventing wobbling after assembly.

[0017] The working principle is as follows: When it is necessary to splice the first base frame 1, the second base frame 2, or the third base frame 3, first place the first base frame 1 in a suitable position, and then rotate the corresponding adjusting screw 5 according to the actual ground conditions. Then, screw the rotating adjusting screw 5 into the heightening welding nut 4 on one side of the first base frame 1 in sequence. When screwing, the base on the adjusting screw 5 should be kept downward. Then, bring the adjacent first base frame 1 close to the placed first base frame 1 so that the snap-fit ​​groove 8 on the adjacent first base frame 1 can be accurately snapped into the position of the snap plate 7 on the other first base frame 1. This allows the two first base frames 1 to be spliced. After splicing, simply use a wrench that matches the groove on the adjusting screw 5 to easily rotate the base of the adjusting screw 5 to contact the ground, so that it can easily support and maintain the balance of the first base frame 1. By repeating the above splicing and leveling installation steps, the first base frame 1 can be easily and quickly supported and used.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
