Description

Technical Field

[0001] This utility model belongs to the field of splicing technology between building panels, and specifically relates to a novel invisible connecting column structure. Background Technology

[0002] In the construction industry, in order to speed up on-site construction, panels are usually produced in factories and then assembled on-site to form structures such as walls and floors. Among them, the splicing technology between panels is the key technology to realize the prefabrication of wall and floor structures.

[0003] Traditional splicing methods, such as flat-joint wall panels, require glue to fill the gaps, while V-joint wall panels suffer from uneven installation defects. Although existing seamless wall panels use a snap-fit ​​structure to achieve rapid splicing, they still have the following technical bottlenecks: existing snap-fit ​​splicing requires secondary grooving to process the mortise and tenon structure, which increases processing complexity and costs. At the same time, the mortise and tenon contact surface is designed in a stepped shape, which is prone to stress concentration and deformation during thermal expansion and contraction.

[0004] Therefore, the inventors designed a new type of invisible connecting column structure. Utility Model Content

[0005] The purpose of this invention is to provide a novel invisible connecting column structure that enables rapid connection between plates and can be hidden inside.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A novel concealed connecting column structure is characterized by comprising a first connecting column and a second connecting column. The first connecting column and the second connecting column are respectively fixedly installed on the side of the inner support layer of two panels that need to be spliced ​​together. The connection between the two panels is achieved through the connection between the first connecting column and the second connecting column. Both the first connecting column and the second connecting column are hidden inside the surface layer of the panels. The first connecting column and the second connecting column that need to be connected are close together. A connecting buckle is fixedly provided on the side of the first connecting column, and a buckle hole is provided on the side of the second connecting column. The connecting buckle is tightly fastened in the buckle hole. A sealing groove is provided at the front of the connection seam between the first connecting column and the second connecting column, and a waterproof strip is embedded in the sealing groove.

[0008] A further technical solution of this utility model is as follows: the connecting buckle includes a mounting base plate and a connector fixed on the front side of the mounting base plate. The side of the first connecting post is provided with a mounting hole. The mounting base plate of the connecting buckle is fixedly connected to the inner side of the mounting hole. The connector of the connecting buckle extends out from the mounting hole to the outer side and is used to connect with the buckle hole.

[0009] A further technical solution of this utility model is as follows: the connector includes a cylindrical connecting part and an annular limiting part set at the front end. The buckle hole is a butterfly hole with an upper end larger than the annular limiting part and a lower end narrower. When connecting, the connector enters from the upper end of the buckle hole and slides downward to lock into the lower end of the buckle hole.

[0010] A further technical solution of this utility model is that the inner surface of the annular limiting part is a conical surface.

[0011] A further technical solution of this utility model is: the front corners of the first connecting post and the second connecting post are respectively recessed, thereby forming a sealing groove.

[0012] A further technical solution of this utility model is: the joint between the surfaces of the two boards that need to be spliced ​​together is filled with sealant.

[0013] A further technical solution of this utility model is as follows: the inner support layer of the plate includes a metal frame, and the first connecting column and the second connecting column are both fixedly connected to the metal frame by threaded connectors.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model adds a first connecting post and a second connecting post to the inner side of the board, and sets a connecting buckle and a buckle hole on the first connecting post and the second connecting post respectively. When connecting the boards, the connecting buckle is fastened into the buckle hole to achieve the connection. The connection efficiency is high. After the connection, the connecting post will be hidden inside the surface of the board and will not be exposed. In addition, a waterproof strip is provided in front of the joint to make the splice waterproof. Attached Figure Description

[0029] The present invention will be further described below with reference to embodiments.

[0030] Example 1:

[0031] like Figures 1 to 7As shown, two panels that need to be spliced ​​together are connected using the novel invisible connecting column structure of this embodiment. The splicing of panels typically involves splicing along a straight line and splicing at corners; this embodiment illustrates the splicing of two panels along a straight line. The panels involved mainly include an inner support layer 300 and a surface layer 400 fixed to the front of the inner support layer 300. The inner support layer 300 provides support strength for the panels, and the surface layer 400 can be made of ceramic tile, wood panel, slab, marble slab, color steel plate, etc. The inner support layer 300 includes a grooved metal frame 301 and an aluminum honeycomb panel 302 located in the recessed space of the metal frame 301. Of course, in other embodiments, the novel invisible connecting column structure of this embodiment can also be used in panels with other structures; the panel in this embodiment is just one example.

[0032] The novel concealed connecting column structure of this embodiment includes a first connecting column 100 and a second connecting column 200. Both the first connecting column 100 and the second connecting column 200 are square tubes and can be made of materials such as aluminum or stainless steel. The first connecting column 100 and the second connecting column 200 are respectively fixed to the side of the inner support layer 300 of the two plates that need to be spliced ​​together. Specifically, they are fixed to the metal frame 301 by a first screw 303, which is a threaded connector.

[0033] The side of the surface layer 400 of the board extends to the front of the connecting column, so that the first connecting column 100 and the second connecting column 200 are both hidden inside the surface layer 400 of the board. In this way, after the connection is made, the connecting column will be hidden inside and will not be exposed, ensuring that the aesthetics of the wall or floor formed by splicing will not be affected.

[0034] like Figure 3 As shown, in this embodiment, connecting buckles 600 are fixed at intervals along the height direction on the side of the first connecting post 100. Specifically, the connecting buckle 600 includes a mounting base plate 603 and a connector. The connector is fixed to the front of the mounting base plate 603 by a second screw 605. The side of the first connecting post 100 has a mounting hole 101. In this embodiment, both the mounting base plate 603 and the mounting hole 101 are square. The width of the mounting hole 603 is greater than the width of the mounting base plate 603, allowing the mounting base plate 603 to pass through the mounting hole 101 from the outside. The mounting base plate 603 is fixedly connected to the inside of the mounting hole 101 by a third screw 606, making the mounting base plate 603 hidden inside. The head of the third screw 606 is recessed into a countersunk hole on the side of the first connecting post 100, keeping the side of the first connecting post 100 flat. The connector of the connecting buckle 600 protrudes from the mounting hole 101 to the outside. Figure 6As shown, the connector includes a cylindrical connecting part 602 and an annular limiting part 601. The rear end of the cylindrical connecting part 602 is fixedly connected to the mounting base plate 603. The annular limiting part 601 is located at the front end of the cylindrical connecting part 602. The diameter of the annular limiting part 601 is larger than that of the cylindrical connecting part 602. The inner surface of the annular limiting part 601 is a conical surface 604.

[0035] like Figure 2 As shown, a buckle hole 201 is provided on the side of the second connecting post 200. In this embodiment, the buckle hole 201 is a butterfly hole with an upper end size larger than the annular limiting part 601 and a lower end width that narrows. The lower end width of the buckle hole 201 is smaller than the diameter of the annular limiting part 601. When connecting, the connector enters from the upper end of the buckle hole 201 and slides down to lock onto the lower end of the buckle hole 201. After the connection is completed, the tapered surface 604 contacts the inner side of the lower end of the buckle hole 201. The tapered surface 604 enables the first connecting post 100 and the second connecting post 200 to fit tightly together.

[0036] In this embodiment, the front corners of the first connecting post 100 and the second connecting post 200 are respectively recessed, thereby forming a sealing groove 501 at the front of the joint between the first connecting post 100 and the second connecting post 200. A waterproof strip 500 is embedded in the sealing groove 501, thereby achieving sealing and waterproofing at the joint.

[0037] The position of the first screw 303 connecting the first connecting post 100 corresponds to the position of the mounting hole 101, and the position of the first screw 303 connecting the second connecting post 200 corresponds to the position of the snap hole 201.

[0038] The process of splicing the panels using the novel invisible connecting column structure in this embodiment is as follows:

[0039] Before installation, the first connecting post 100 and the second connecting post 200 must be fixedly installed. Specifically, the first connecting post 100 and the second connecting post 200 are respectively attached to the sides of the inner support layer 300 of the board, and the first screw 303 is installed through the mounting hole 101 or the snap hole 201, thereby fixing the first connecting post 100 and the second connecting post 200 to the boards to be spliced. Then, the mounting base plate 603 of the connecting buckle 600 is inserted into the inside of the mounting hole 101, and the third screw 606 is connected to fix the connecting buckle 600 in place.

[0040] During splicing, a waterproof strip 500 is placed at the sealing groove 501. The first connecting post 100 and the second connecting post 200 of the two boards to be spliced ​​are then placed together, with the connectors entering from the upper end of the snap hole 201. The boards are then slid relative to each other, causing the connectors to slide downwards and engage with the lower end of the snap hole 201. The tapered surface 604 tightens the first connecting post 100 and the second connecting post 200 together. A sealant 401 is then filled into the joint between the surfaces 400 of the two boards. The sealant 401 can be a grout, cement, or a special filler powder, etc., to complete the splicing.

[0041] Example 2:

[0042] like Figure 8 As shown, Embodiment 2 involves splicing two perpendicular plates. The connecting buckle 600 is fixed on the side of the first connecting post 100 facing the second connecting post 200. The splicing between the two plates is also achieved through the novel invisible connecting post structure.

[0043] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
