Description

Technical Field

[0001] The utility model belongs to the technical field of floor installation, and in particular relates to an assembled floor component. Background Art

[0002] Floors are panels installed on the ground. According to their materials, they can be divided into wooden floors, cement floors, ceramic tiles and other floors. For floors made of materials such as cement tiles, a cement layer needs to be laid on the ground, and then the floors are laid one by one. This method is the mainstream method of floor laying at present, but the disadvantages are also very obvious:

[0003] It is reflected in: 1. The construction period is relatively long. Specifically, the laying is cumbersome and requires laying a cement layer. The drying of the cement layer takes time. In addition, during the laying process, cement needs to be applied to the back of the tile. When the laying surface is large, the workload is very large;

[0004] 2. During the later use, once the floor cracks or breaks, it will be cumbersome to repair and replace it. It is necessary to break the damaged tiles in advance, hollow out the laying position randomly, and then lay the cement base before laying the tiles.

[0005] 3. Most electrical wires and water pipes can only be buried under the paved ground. Once repair and maintenance are required, the floor needs to be removed, and the inspection is cumbersome.

[0006] Similarly, although wooden floors are simpler to lay than ceramic tiles and other floors, they are also more complicated to lay. Similarly, when electrical wires, water pipes and other components laid underground fail, it is very difficult to troubleshoot. In addition, wooden floors are expensive to build and the cost of laying them is relatively high.

[0007] Therefore, based on the above-mentioned determination of traditional floor tiles, the current assembly method of floor laying is gradually replacing the traditional method. The assembly method of floor laying is not only easier to lay, but also the assembly method of floor adopts a hollow design, so it is convenient to run wires and lay pipes at the bottom of the floor, and once a fault occurs, it can be easily and quickly detected, and it can be installed immediately after maintenance, which is very economical and practical.

[0008] However, due to the hollow design of the assembled floor, its stability is not high. As the use time increases, the gaps between the floors gradually increase, resulting in a decrease in its aesthetics. The fundamental reason is that the skeleton of the assembled floor shifts relative to each other as the use time increases. After the traditional lock structure is buckled, as the floor skeleton deviates, the lock structure is easy to detach and dislocate. Utility Model Content

[0009] Based on the above background, the purpose of the utility model is to provide a prefabricated floor assembly.

[0010] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0011] An assembled floor assembly comprises a plurality of sequentially assembled floor units, wherein the floor units comprise a motherboard and a sub-board assembled on the motherboard;

[0012] The motherboard and the daughterboard both include a board frame, and the board frame is fixedly connected with a plurality of horizontal frames arranged in parallel and a plurality of vertical frames arranged perpendicular to the horizontal frames and in parallel;

[0013] A plurality of filling holes are formed between the horizontal frame and the vertical frame, and the filling holes are filled with insulation boards;

[0014] The motherboard and the daughterboard are assembled by a snap-on structure;

[0015] The clamping structure includes a plurality of clamping holes opened on the side of the motherboard, and the daughterboard is integrally formed with a plurality of clamping protrusions clamped on the clamping holes;

[0016] The clamping protrusion and the clamping socket are locked by an elastic locking structure;

[0017] After the motherboard and the daughterboard are assembled, the floor is installed on the top surface of the motherboard and the daughterboard.

[0018] Preferably, the bottoms of the motherboard and the daughterboard are fixedly connected with a plurality of height-adjusting support members;

[0019] The height-adjusting support comprises a base installed on the installation ground, and a height-adjusting screw is threadedly connected to the top of the base;

[0020] The height adjustment screw is threadedly connected to the corresponding motherboard and the daughterboard.

[0021] Preferably, the bayonet includes a rectangular bayonet portion and an arc-shaped bayonet portion integrally formed with the rectangular bayonet portion;

[0022] The clamping protrusion includes a rectangular protrusion matched with the rectangular bayonet portion and an arcuate protrusion integrally formed with the rectangular protrusion; the arcuate protrusion matches with the arcuate bayonet portion;

[0023] The elastic locking structure is arranged on the rectangular convex part.

[0024] Preferably, the elastic locking structure comprises two locking balls elastically mounted on the side walls of the rectangular protrusion respectively, and the side walls of the rectangular bayonet portion are respectively provided with locking grooves for locking the locking balls.

[0025] Preferably, the locking ball includes a spherical portion that is locked in the locking groove, the spherical portion is integrally formed with a cylindrical portion, the rectangular convex portion is provided with a sliding groove connected to a cylindrical groove of the cylindrical portion, the cylindrical portion is fixedly connected with a small spring, and the small spring is fixedly connected in the cylindrical groove.

[0026] Preferably, the bottom of each of the floor units is fixedly connected with a reinforcing rib structure;

[0027] The reinforcing rib structures are respectively located at the bottom of the motherboard and the sub-board.

[0028] Preferably, the reinforcing rib structure comprises a plurality of longitudinal ribs and transverse ribs arranged alternately with the longitudinal ribs;

[0029] The longitudinal ribs are fixedly connected to the bottom of the longitudinal frame, and the transverse ribs are fixedly connected to the bottom of the transverse frame.

[0030] Preferably, the longitudinal ribs and the transverse ribs are both curved.

[0031] Preferably, a plurality of mounting threaded holes are respectively provided on the top surfaces of the motherboard and the sub-board, and the floor is fastened to the mounting threaded holes by bolts.

[0032] The utility model has the following beneficial effects:

[0033] 1. During the working process, when the mother and child boards are assembled, they push each other directly. Since the card ball is curved, it is inserted into the card slot. During the insertion process, the small spring is compressed. This method can achieve convenient card connection and installation. The card ball and card slot on both sides cooperate to fully connect and install the mother and child boards. The advantages of this card connection structure are not only high card connection stability, but also convenient disassembly. Specifically, in the actual working process, the mother and child boards need to be separated by force during maintenance and disassembly. Because of the curved card ball and curved card slot design, they can be pulled apart relatively easily. However, traditional lock buckles are very easy to break after a little force due to aging after years of use, and it is more troublesome to disassemble. And as the force time increases, the lock buckle structure is easy to loosen.

[0034] 2. The reinforcing rib structure is designed to improve the deformation resistance of the mother-child board. Specifically, the reinforcing rib structure includes a plurality of longitudinal ribs and transverse ribs staggered with the longitudinal ribs; the longitudinal ribs are fixedly connected to the bottom of the longitudinal frame, and the transverse ribs are fixedly connected to the bottom of the transverse frame. The shapes of the longitudinal ribs and the transverse ribs are both curved. The curved shape design increases its pulling surface, thereby further enhancing the stability of the mother-child board.

[0045] Example 1

[0046] like Figure 1-5 As shown, a prefabricated floor assembly includes a plurality of floor units assembled in sequence, wherein the floor unit includes a motherboard 1 and a sub-board 2 assembled on the motherboard 1 (specifically, one motherboard 1 and four sub-boards 2 form a unit, and the construction is carried out according to the unit combination, which is not only efficient but also greatly reduces the construction workload). At the same time, according to the existing method, a plurality of mounting threaded holes (not shown in the figure) are respectively opened on the top surfaces of the motherboard 1 and the sub-board 2, and the floor (not shown in the figure) is fastened to the mounting threaded holes by bolts.

[0047] The motherboard 1 and the subboard 2 are used in a snap-fit ​​manner to prevent the motherboard 1 and the subboard 2 from being dislocated during the actual working process. Specifically, the motherboard 1 and the subboard 2 are assembled through a snap-fit ​​structure; the snap-fit ​​structure includes a plurality of snap-fit ​​ports 11 opened on the side of the motherboard 1, and the subboard 2 is integrally formed with a plurality of snap-fit ​​protrusions 21 snap-fitted to the snap-fit ​​ports 11; the snap-fit ​​protrusions 21 and the snap-fit ​​ports 11 are locked by an elastic lock structure; after the motherboard 1 and the subboard 2 are assembled, the floor is installed on the top surface of the motherboard 1 and the subboard 2.

[0048] The above-mentioned snap-fit ​​structure is located on the four side walls of the motherboard 1 and the daughterboard 2. Therefore, the motherboard 1 and the daughterboard 2 are snapped together from the four sides, and then the motherboard 1 and the daughterboard 2 are fully snapped into one body, so that the motherboard 1 and the daughterboard 2 do not loosen during the working process.

[0049] By improving the snap-fit ​​structure as follows, the locking force is increased to prevent loosening after long-term use, specifically as follows: the snap-fit ​​11 includes a rectangular snap-fit ​​part and an arc snap-fit ​​part integrally formed with the rectangular snap-fit ​​part; the snap-fit ​​21 includes a rectangular convex part matched with the rectangular snap-fit ​​part and an arc convex part integrally formed with the rectangular convex part; the arc convex part matches with the arc snap-fit ​​part. The snap-fit ​​11-snap-fit ​​21 structure designed in this way realizes seamless snap-fit, and the motherboard 1 and the sub-board 2 are not easy to shake and deviate after assembly.

[0050] Meanwhile, an elastic locking structure is provided on the rectangular protrusion. Specifically, the elastic locking structure includes two locking balls 22 elastically mounted on the side walls of the rectangular protrusion, and the side walls of the rectangular bayonet are respectively provided with a slot for locking the locking balls 22. The locking ball 22 includes a spherical portion that is locked in the slot, and the spherical portion is integrally formed with a columnar portion 221, and the rectangular protrusion is provided with a columnar groove that is connected to the columnar portion 221 by a sliding groove, and a small spring 222 is fixedly connected to the columnar portion 221, and the small spring 222 is fixedly connected in the columnar groove.

[0051] During operation, when the mother and child boards 2 are assembled, they push each other directly. Since the card ball 22 is a curved surface, the card ball 22 is inserted into the card slot. During the insertion process, the small spring 222 is compressed. This method is used to facilitate the card connection and installation. The card balls 22 and card slots on both sides cooperate to fully connect and install the mother and child boards 2.

[0052] The advantages of this clamping structure are not only high clamping stability, but also convenient disassembly. Specifically, in the actual work process, when it is necessary to repair and disassemble, the mother and child boards 2 are separated by force. Because of the curved clamping ball 22 and the curved clamping groove design, they can be pulled out relatively easily. However, the traditional lock buckle is very easy to break after a little force due to aging after years of use, and it is more troublesome to disassemble. And as the force is applied for a longer time, the lock buckle structure is easy to loosen.

[0053] Example 2

[0054] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the motherboard 1 and the sub-board 2 include a board frame, on which are fixedly connected a plurality of horizontal frames 32 arranged in parallel and a plurality of vertical frames 31 arranged perpendicular to and in parallel with the horizontal frames 32; a plurality of filling holes 33 are formed between the horizontal frames 32 and the vertical frames 31, and according to the existing method, the filling holes 33 are filled with insulation boards of suitable shape and size.

[0055] At the same time, similar to the existing method, the bottom of the motherboard 1 and the daughterboard 2 are fixedly connected with several height adjustment support members 4; the height adjustment support member 4 includes a base installed on the installation ground, and the top of the base is threadedly connected with a height adjustment screw; the height adjustment screw is threadedly connected to the corresponding motherboard 1 and daughterboard 2.

[0056] During construction, the height is adjusted by raising the support members to ensure the flatness of the paving.

[0057] Example 3

[0058] like Figure 1-5As shown, in this embodiment, based on the structure of embodiment 1, the bottom of the floor unit is fixedly connected with a reinforcing rib structure 5. The reinforcing rib structure 5 is used to increase the stability of the structure of the mother-child board 2, such as the compression resistance and deformation resistance, to avoid deformation of the mother-child board 2 during long-term use, resulting in an increase in gaps.

[0059] Specifically, the reinforcing rib structure 5 is located at the bottom of the motherboard 1 and the sub-board 2 respectively.

[0060] The reinforcing rib structure 5 adopts the following structural design to improve the reinforcing deformation resistance of the mother-child board 2. Specifically, the reinforcing rib structure 5 includes a plurality of longitudinal ribs 52 and transverse ribs 51 staggered with the longitudinal ribs 52; the longitudinal ribs 52 are fixedly connected to the bottom of the longitudinal frame 31, and the transverse ribs 51 are fixedly connected to the bottom of the transverse frame 32.

[0061] The longitudinal ribs 52 and the transverse ribs 51 are both curved. The curved shape design increases the pulling surface, thereby further enhancing the stability of the mother-child board 2.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
