Description

Building fastener device

Technical Field

The utility model relates to a building fastener device especially indicates a can improve stability and convenient to use's building fastener device.

Background

Currently, tiles (or other building boards) are attached to the walls of a building to make the building more beautiful. Traditionally, tile splicing is performed by a so-called wet process, i.e., the tile is directly attached to the whole of the wall surface of a building after applying cement to the wall surface. The wet construction method is easy to construct and low in cost, but under the condition of constant climate change, the ceramic tiles are easily affected by thermal expansion and cold contraction due to large area of the ceramic tiles directly contacting the wall surface, and further are easy to crack or fall off to cause danger.

In order to solve the problems of the above wet construction method, a so-called dry construction method has been developed, in which two inclined slits are formed in a tile, and then supporting plates extending obliquely at both sides of the tile are inserted into the two slits, and the supporting plates are fixed to the wall surface of a building. Under the dry working method, the ceramic tile is less affected by the expansion and contraction of heat.

However, the two supporting portions of the supporting plate are entirely embedded in the slot of the tile, i.e. the tile only obtains supporting force through the two supporting portions, which is relatively insufficient in terms of stability. In addition, the distance between the two support parts is fixed in the dry construction method, so the slot of the tile must be very accurate to align and insert the support parts when the slot is dug (for example, in a construction site), which is not very convenient in use.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Please refer to fig. 1, which is a schematic diagram illustrating a usage status of the first preferred embodiment of the present invention. In fig. 1, there is shown a construction fastener device 1 for hanging and splicing construction boards (e.g. marble, heat insulation boards, etc.) such as ceramic tiles 5 to a wall surface 61 (e.g. an outer wall surface) of a building 6, so as to achieve the purpose of beauty (or heat insulation, etc.) of the building 6.

Please refer to fig. 2 and fig. 3, wherein fig. 2 is a perspective view of a first preferred embodiment of the present invention, and fig. 3 is an exploded view of the first preferred embodiment of the present invention. In fig. 2 and 3, a construction fastener device 1 is shown, which comprises a first supporting plate 2, a second supporting plate 3 and a locking member 4. Wherein, the first supporting plate 2 is bent to form a first assembling portion 21 and a first supporting portion 22 which are staggered with each other, as shown in the figure, the first supporting plate 2 is firstly transversely extended to form the first assembling portion 21, then is bent downwards, and then is transversely bent and extended to form the first supporting portion 22; similarly, the second supporting plate 3 is bent to form a second assembling portion 31 and a second supporting portion 32 which are offset from each other, and the bending manner of the second supporting plate 3 is the same as that of the first supporting plate 2.

The multi-bending design of the first supporting plate 2 and the second supporting plate 3 not only can reduce the risk of deformation caused by thermal expansion and cold contraction, but also can help to buffer the impact force during earthquake.

In the first supporting plate 2, the first assembling portion 21 has a first through hole 211, a portion of the first supporting portion 22 extends with a first engaging portion 221 in a downward slope, and in this embodiment, the other portion of the first supporting portion 22 except the first engaging portion 221 includes a first bottom surface 222; similarly, in the second supporting plate 3, the second assembling portion 31 is provided with a second through hole 311, a portion of the second supporting portion 32 is inclined downward to extend a second engaging portion 321, and in this embodiment, the other portion of the second supporting portion 32 except for the second engaging portion 321 includes a second bottom surface 322, and the first bottom surface 222 and the second bottom surface 322 are located on the same plane.

As can be seen from fig. 2 and 3, the second assembling portion 31 of the second supporting plate 3 and the first assembling portion 21 of the first supporting plate 2 are overlapped with each other such that the second through hole 311 corresponds to the first through hole 211. The first through hole 211 is a slot type in the embodiment, and the second through hole 311 is a circular shape in the embodiment, but not limited thereto, that is, the second through hole 311 may be designed to be a slot type and the first through hole 211 may be designed to be a circular shape at the same time, or both the first through hole 211 and the second through hole 311 may be designed to be slot types. In addition, the first through holes 211 and/or the second through holes 311 are not limited to be formed in a slot shape as a whole, and the first through holes 211 and/or the second through holes 311 may be formed in a slot shape only partially.

In the present embodiment, the first supporting plate 2 is bent to form a space 20, the space 20 is located below the first assembling portion 21, and the second assembling portion 31 is overlapped below the first assembling portion 21 and located in the space 20. The section of the second assembling portion 31 after being bent is in the shape of an inverted U in the present embodiment, but only a part of the second assembling portion 31 may be in the shape of an inverted U after being bent.

In addition, the locking member 4 shown in fig. 2 and 3 includes a bolt 41 and a nut 42, wherein the bolt 41 passes through the first through hole 211 of the first supporting plate 2 and the second through hole 311 of the second supporting plate 3, and the nut 42 is screwed to the bolt 41, thereby locking the first supporting plate 2 and the second supporting plate 3 to each other.

Fig. 4 is a side view of a combination of a building fastener device and a tile according to a first preferred embodiment of the present invention, and fig. 1 to 3 are also provided. As shown in the figure, the tile 5 is obliquely dug with two grooves 51 corresponding to the first engaging portion 221 of the first supporting plate 2 and the second engaging portion 321 of the second supporting plate 3. In this embodiment, the first fitting portion 221 and the second fitting portion 321 are inclined oppositely, so the two grooves 51 of the tile 5 are also inclined oppositely and dug to correspond to the first fitting portion 221 and the second fitting portion 321.

When the tiles 5 are to be hung and attached, the first engaging portion 221 of the first supporting plate 2 and the second engaging portion 321 of the second supporting plate 3 are respectively engaged with the two grooves 51 of the tiles 5, and then the locking member 4 is engaged with other supporting members 62 (e.g., L-shaped iron sheets) to hang and attach the tiles 5 on the wall surface 61 of the building 6. In practical use, the building fastener device 1 can be used alone without being matched with other supporting members and directly locked on the wall surface, i.e. the building fastener device can be used in multiple purposes.

The above-mentioned construction fastener device 1 can hang the tile 5 in such a way that the first engaging portion 221 and the second engaging portion 321 are designed like eagle claw (claw type) to firmly fasten the construction boards such as tile 5 deeply into the root, so that the construction boards, even the large-sized construction boards, can be more securely and firmly combined with the wall surface 61 of the building 6. In addition, the building fastener device 1 is located behind the tile 5, which can hide the building fastener device 1 on the back of the building board, so that the whole visual effect on the front of the building board is more beautiful.

When the first engaging portion 221 of the first supporting plate 2 and the second engaging portion 321 of the second supporting plate 3 are respectively engaged with the two grooves 51 of the tile 5, a slight error may be generated in the positions of the two grooves 51 due to practical construction, and at this time, the relative position between the first supporting plate 2 and the second supporting plate 3 can be finely adjusted by using the structural design of the slot-shaped through hole, so that the first engaging portion 221 and the second engaging portion 321 are respectively engaged with the two grooves 51. In other words, the structural design of the slot-shaped through hole can improve the convenience of use. Furthermore, as mentioned above, the second assembling portion 31 is bent in an inverted U-shape, so that the structural strength can be increased, and the second assembling portion 31 can be prevented from interfering with the first supporting plate 2 when the position between the first supporting plate 2 and the second supporting plate 3 is to be finely adjusted.

Through the structure design, the ceramic tile 5 can be directly processed and hung on the building fastener device 1 on site, and the effects of safety, firmness, quick assembly and flexible application are achieved.

In addition, the other portions of the first supporting portion 22 except the first engaging portion 221 and the other portions of the second supporting portion 32 except the second engaging portion 321 can also be used to support the tile 5, so as to relatively improve the stability of the tile 5. In detail, referring to fig. 4, the first bottom surface 222 of the other portion of the first supporting portion 22 except the first engaging portion 221 and the second bottom surface 322 of the other portion of the second supporting portion 32 except the second engaging portion 321 are located on the same plane, so that the other portions directly contact the tile 5 to increase the contact area therebetween, thereby increasing the frictional supporting force, and furthermore, an adhesive (not shown) such as epoxy resin may be further coated between the other portions and the tile 5 to further improve the stability when the tile 5 is hung and tiled.

It should be noted that one tile 5 is not limited to fit only one construction fastener device 1, in other words, depending on the size of the tile 5, one tile 5 can fit multiple construction fastener devices 1, and the position of the recessed groove 51 of the tile 5 (i.e. the position where the construction fastener device 1 hangs the tile 5) can also be varied according to the actual requirement, for example, the recessed groove 51 can be disposed at any position of the middle or edge of the tile 5.
