Description

Building material panel connectors

The invention relates to a connecting piece connected between a building material panel and a wall or a ceiling, especially a building material panel connecting piece for dry construction.

In the prior art, when the building material panels are installed on the wall, if the building material panels are heavy or more attention is paid to safety, dry construction is often used to fix the building material panels. The common dry construction is to use two L-shaped plates between the wall and the building material boards. The vertical boards of the two L-shaped boards are respectively locked on the wall and the building material boards, and the horizontal boards of the two L-shaped boards are locked up and down. After stacking and leaning against each other, a carriage bolt is used to vertically penetrate and lock the horizontal plate body of the two L-shaped plates, thereby fixing the building material plate body on the wall through the two L-shaped plates. However, such a fixing method requires a certain distance between the wall and the building material board. There are two main reasons:

First, in order to allow the horizontal plates of the two L-shaped plates to stack up and down, and to form holes on the L-shaped plates for the carriage bolts to pass through, the horizontal plates of the L-shaped plates must have a certain length, specifically The minimum length of the horizontal plate body is also 3 centimeters, and this results in a distance of at least 3 centimeters between the building material plate body and the wall, and is usually about 5 to 10 centimeters.

Second, the carriage bolts need to be rotated by tools, and in order to allow the tools to be operated and rotated, there must be a certain distance between the wall and the building material board as the operating space.

Therefore, there must be a certain distance between walls and building material panels, and this distance will be compressed to the indoor space. Moreover, the building material panels on the front, rear, left, and right sides protrude inward, and the overall indoor space is actually reduced a lot, especially now that every inch of land is expensive, and it is necessary to avoid space restriction as much as possible. Therefore, the way of fixing the building material panels in the prior art, Really needs to be improved.

In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a building material panel connector, which can greatly reduce the distance between the building material panel and the wall or ceiling.

In order to achieve the above creation purpose, the technical means used in this creation is to design a building material panel connector (first embodiment), which is used to connect a joint surface and a building material panel, and one side of the building material panel An engaging groove is concavely formed; the building material plate body connector includes a base plate, which passes through an inner hole and an outer hole; and used to fix the base plate on the joint surface; an outer connecting piece, which has an opposite inner end and an outer end, and the inner end of the outer connecting piece is threaded through the outer hole screwed on the base plate The inner hole and the outer hole of the base plate are parallel to each other, and the outer end of the outer connecting piece is adjacent to the engaging groove of the building material board body; an engaging disc is sleeved and screwed to the outer connecting piece, And it is used to pass through the engaging groove of the building material board.

In order to achieve the above creation purpose, this creation further provides a building material board connector (second embodiment), which is used to connect a joint surface and a building material board body, and one side of the building material board body is concavely formed with a card The joint groove; the building material plate body connector includes an external piece, which is used to pass through and fix in the joint surface; an engaging plate, which is sleeved and screwed to the external piece, and is used to pass through the building material plate in the engaging groove of the body.

When this creation is used, in the first embodiment, firstly, the base plate is attached to the joint surface (wall or ceiling), and then the internal connector penetrates the inner hole of the base plate and is fixed in the joint face, so as to fix the base plate on the joint surface. on the surface; then move the building material board to the position corresponding to the outer hole of the base plate on the side of the building material board, and then insert the engaging disk into the engaging groove on the side of the building material board (pre-processed shape) In the last step, it is enough to pass the outer connecting piece through the outer hole of the screw-fitting plate and the substrate, so that the engaging plate is connected to the substrate through the outer connecting piece, the substrate is fixed on the joint surface through the inner connecting piece, and the engaging plate is also At the same time, the building material board is restricted by the through-fitting groove.

In the second embodiment, after the building material board is moved to the position to be installed, the engaging plate is penetrated into the engaging groove on the side of the building material plate, and then the external parts are threaded through the engaging plate And it just needs to be threaded and combined in the joint surface (wall or ceiling). In this way, the engaging plate is connected to the joint surface through the external parts, and the engaging plate also restricts the building material board by passing through the engaging groove.

When using this creation, you can use the same two sets of this creation at the same time:

When used on the wall, two sets of original creations are respectively used on the bottom side and top side of the upright building material board. For this creation on the bottom side, the engaging disc hooks the bottom side of the building material board, and the external parts support the building material board upward; for this creation on the top side, the engaging disc hooks the top side of the building material board. Therefore, the two sets of book creations can hook up and down the building material board so that it will not fall inside and outside, and can also support the building material board.

When used in the ceiling, two sets of original creations are respectively used on opposite sides of the horizontal building material board. At this time, the external parts can be used to limit the lateral movement of the building material board, and the clamping plate supports the building material board upwards.

The advantage of this creation is that when the first embodiment is assembled at the beginning, that is, when the inner connector fixes the base plate on the joint surface, the building material plate body has not been installed, so the construction space will not be limited by the building material plate body to facilitate construction; and In the second embodiment, this step may not be required. Then, when the building material board moves closer, it is only necessary to rotate the external connection part (for example, through an electric tool), and the external connection part will continuously move toward the base plate due to screwing and finally screw the engaging disc and the base plate at the same time (first embodiment) or Simultaneously, the engaging plate is screwed and inserted into the joint surface (the second embodiment). At this time, although there is a building material plate body and the construction space is limited, only the external parts need to be simply rotated, so the construction can still be carried out easily. The overall installation process of this creation is quite simple.

And, the installation of the external connection part of this creation only needs to be constructed (rotated) from the outside, and does not need to be constructed between the building material board body and the wall (or ceiling), so it is not necessary to reserve construction space and the distance can be reduced. Finally, compared with the prior art that uses two L-shaped boards stacked up and down and requires a certain distance, in the first embodiment of this creation, there is only one wall (or ceiling) between the building material board and the wall (or ceiling). ) substrate, so the spacing can be greatly reduced; in the second embodiment, it can even be considered that there is no element between the building material board and the wall (or ceiling), and the spacing can even be reduced to 0.1 cm at this time, so this creation can be greatly improved. Reduce spacing.

This creation achieves the creative purpose of facilitating construction and reducing the distance between the building material board body and the wall (or ceiling) by this.

The advantage of this invention is that at the beginning of assembly, that is, when the inner connector 20 fixes the base plate 10 on the joint surface 90, the building material plate body 80 has not been installed, so the construction space will not be limited by the building material plate body 80 to facilitate construction. Then when the building material board 80 moves closer, it is only necessary to rotate (preferably with an electric tool) the external connection part 30 (for example, from the non-circular groove 31), and the external connection part 30 will continuously move towards the base plate 10 due to screwing and finally screw simultaneously. Although the construction space is limited due to the building material board body 80 at this time when the joint plate 40 and the base plate 10 are engaged, only the external connecting member 30 needs to be simply rotated, so the construction can still be carried out easily. The overall installation process of this creation is quite simple.

Moreover, the installation of the external connection piece 30 of the present invention only needs to be constructed (rotated) from the outside. Even when it is disassembled, the external connection piece 30 can also be rotated from the gap between the two building material boards 80. Construction is carried out between the board body 80 and the wall (or ceiling), so there is no need to reserve construction space and the distance can be reduced. Furthermore, there is only one base plate 10 attached to the wall (or ceiling) between the building material board body 80 and the wall (or ceiling), so the distance can be greatly reduced.

This creation achieves the creative purpose of facilitating construction and reducing the distance between the building material board body and the wall (or ceiling) by this.

In addition, during the installation process, the inner hole 11 of the substrate 10 is a long hole to facilitate adjusting the position of the substrate 10 , and then adjust the position of the outer connecting member 30 relative to the inner connecting member 20 . After the building material panels 80 are installed, the positions of the engaging disc 40 and the building material panels 80 can also be fine-tuned by rotating the external member 30 (adjusting the spacing), so that the spacing between all the building material panels 80 relative to the joint surface 90 can be consistent .

This creation can be used for building exterior walls, interior decoration, light partitions, wooden partitions, etc. This creation is mainly used for dry construction, but it is also possible to further coat cement mortar.

Please refer to FIG. 6 and FIG. 7 , the present invention may further include a lamp 60 connected to an outer end of the external member 30 , and the lamp 60 may be an LED lamp or other light-emitting elements. And preferably, the external connection part 30 is a tubular body, and the wires of the lamp 60 are inserted into the external connection part 30 from the outer end of the external connection part 30, and then run out from the inner end or the side wall of the external connection part 30, thereby The wires can be hidden behind the building material board body 80 .

Moreover, the present invention can further have a reinforcing piece 70, which is sheathed and screwed to the outer connecting piece 30, and is used to abut against an outer surface of the building material plate 80, whereby it can double abut against the building material together with the engaging plate 40 The board body 80 is especially suitable for the situation of hanging the ceiling upside down, and can achieve the effect of double support. In addition, an accommodating groove 82 can be correspondingly provided on the outer surface of the building material board body 80 to accommodate the reinforcing piece 70 , so as to prevent the reinforcing piece 70 from protruding from the outer surface of the building material board body 80 .

In the foregoing embodiments, the base plate 10 is flat, but please refer to FIG. 8 , in another embodiment, the base plate 10 may include an inner plate portion 13 and an outer plate portion 14 . The inner plate portion 13 is used to abut against the joint surface 90 , and the outer plate portion 14 is more protruding than the inner plate portion 13 (closer to the building material plate body 80 ). The inner hole 11 is formed on the inner plate portion 13 , and the outer hole 12 is formed on the outer plate portion 14 . This can be applied to various purposes, and when necessary, the outer plate portion 14 can also be made to lean against the inner surface of the building material plate body 80, so that the building material plate body 80 and the joint surface 90 are clamped against the base plate 10 to ensure that each The distance between a building material plate body 80 and the joint surface 90 is consistent.

Please refer to Fig. 9, the second embodiment of the building material board connector of this invention is similar to the first embodiment, the only difference is that the second embodiment does not have the base plate 10 and the inner connector 20, but directly uses the outer connector 30 To be fixed on the joint surface 90 by passing through, the outer connecting member 30 can preferably be an internal compression bolt, an auxetic bolt (anchor bolt) or a self-tapping screw, but not limited thereto. In this way, the structure is simplified. For example, when the external connection part 30 is an internal force bolt, the expansion sleeve 32 is first placed in the groove of the joint surface 90, and then the locking plate 40 is placed on the locking plate body 80 of the building material. In the groove 81, then rotate the outer connecting piece 30 so that it finally screws the engaging disc 40 and the expansion sleeve 32 at the same time and then expands the expansion sleeve 32. For example, if the external connection part 30 is a self-tapping screw, the engaging disc 40 is placed in the engaging groove 81 of the building material board body 80, and then the external connecting part 30 is directly rotated so that it is finally screwed to the engaging disc 40 at the same time and fixed. Just within the joint surface 90 .

In the second embodiment, there is no element between the building material board 80 and the wall (or ceiling), so the distance between the building material board 80 and the joint surface 90 can be reduced to 0.1 cm, which can greatly reduce the distance.

The second embodiment differs from the first embodiment only in the way of bonding to the joint surface 90, and the rest are roughly the same, for example, the engaging plate 40 is a circular plate, the external connection part 30 has a non-circular groove 31, and further includes a lamp 60 and a reinforcement The part 70 and the external connection part 30 are pipe bodies and the like, which will not be repeated here.
