Description

Technical Field

[0001] The present invention relates to a building material, particularly to a connection component for connecting and supporting two adjacent building material plates and fixing them to a wall. Background Art

[0002] In the prior art, two adjacent building material plates (such as stone slabs or tiles) need to be fixed to a wall through an iron part group respectively. Each iron part group includes two L-shaped iron parts and at least one set of bolts and nuts. This method has many installation procedures and can only be operated on-site during construction. The constructor must reach into the space between the building material plate and the wall to assemble and combine the two L-shaped iron parts, and then fix them with fixing parts such as bolts and nuts.

[0003] However, generally, the gap between the building material plate and the wall is usually very narrow, and it is actually not convenient for users to reach into it. If further complicated procedures such as assembling the two L-shaped iron parts and fixing the bolts are to be carried out, it will be quite difficult. In addition, if it is found that the position of the building material plate needs to be adjusted after construction is completed, the whole installation must be removed and reinstalled.

[0073] The following further elaborates on the technical means adopted by the present invention to achieve the intended invention purpose in conjunction with the drawings and the preferred embodiments of the present invention.

[0074] Please refer to Figure 1 、 Figure 3 、 Figure 7 and Figure 10 , the present invention is used to be combined with a first building material board body A1 and a second building material board body A2, and fix the first building material board body A1 and the second building material board body A2 on a wall A3. The first building material board body A1 and the second building material board body A2 can be arranged vertically or horizontally. The present invention mainly includes two forms: a three-piece form and a two-piece form. Among them, the three-piece form includes three connecting members, and the two-piece form includes two connecting members. In these two forms, each connecting member is formed by cutting or bending a metal sheet. And regardless of which form, the preferred structures for combining with the first building material board body A1 and the second building material board body A2 include three types, namely lock holes, flat cone pieces, and eight-shaped pieces; and, the preferred combination methods between these connecting members include four types, namely central single socket type, T-shaped socket type, double notch type on both sides, and left-right dislocation type.

[0075] That is to say, through the permutation and combination of three combination structures with the building material board body and four combination methods between the connecting members, the three-piece form and the two-piece form can each form twelve preferred embodiments, a total of twenty-four preferred embodiments. In order to completely and concisely illustrate each structure, the following only takes four preferred embodiments with the lowest combination repeatability of each structure as the main illustrative embodiments, without repeating each structure by combining and matching one by one, but the combination of each structure is not limited to the following combinations.

[0076] Please refer to Figure 1 、 Figure 2 and Figure 3 , the first embodiment of the present invention is a three-piece type, and adopts a keyhole structure with a left-right dislocation type. In the first embodiment, the composite building material board body connection component includes a first connecting piece 10, a second connecting piece 20 and a third connecting piece 30, that is, a three-piece type.

[0077] The first connecting piece 10 includes a first flat part 11, a first joint part 12 and a first connecting part 13. The first flat part 11 is parallel to the first building material board body A1 and is adjacent to or abuts against the first building material board body A1. The direction of the first building material board body A1 facing the first flat part 11 is defined as an installation direction, or backward, and vice versa is forward. The first joint part 12 is formed on the first flat part 11 and is used for joining with the first building material board body A1. Specifically, in the first embodiment, the first building material board body A1 has a board body joint hole, and the first joint part 12 is a through hole formed through the first flat part 11 and is used for a fixing member (such as a screw) to pass through and be inserted and joined with the board body joint hole, that is, a keyhole structure. The board body joint hole is a general screw hole in the first embodiment, so that the fixing member can be directly locked to the first building material board body A1 through the through hole of the first joint part 12. Or, in other embodiments of the keyhole structure, the board body joint hole can also be a two-stage hole (for the specific description of the two-stage hole, please refer to the third embodiment). In this way, the through hole of the first joint part 12 can also be matched with the screw head of a screw or the outer clamping part of a connecting rod to be inserted into the two-stage hole, so as to hang the first building material board body A1. In addition, the first joint part 12 is a long through hole extending up and down, so that it is convenient to adjust the position after the screw is locked up and down. The first connecting part 13 is formed on the first flat part 11. Specifically, the first connecting part 13 is a tab protruding from the edge of the first flat part 11 and deviates from the center of the first flat part 11 in the direction perpendicular to the installation direction (such as the up-down direction or the left-right direction).

[0078] The second connecting member 20 and the first connecting member 10 are arranged vertically, and include a second flat portion 21, a second engaging portion 22, and a second connecting portion 23. The second flat portion 21 is parallel to the second building material plate body A2, adjacent to or abuts against the second building material plate body A2, and the second flat portion 21 and the first flat portion 11 are located at the same position in the installation direction (front-back direction), that is to say, both are abutted against the same imaginary plane. The second engaging portion 22 is formed on the second flat portion 21 and is used to engage with the second building material plate body A2. In the first embodiment, the specific structure and use of the second engaging portion 22 are exactly the same as those of the first engaging portion 12, that is, both are keyhole structures, but in other embodiments, the specific structure and use of the second engaging portion 22 can also be different from those of the first engaging portion 12. The second connecting portion 23 is formed on the second flat portion 21 and is engaged with the first connecting portion 13. Specifically, the second connecting portion 23 is a tab protruding from the edge of the second flat portion 21 and deviates from the center of the second flat portion 21 in a direction perpendicular to the installation direction (such as the up-down direction or the left-right direction). The first connecting portion 13 and the second connecting portion 23 are located at the same position in the installation direction (front-back direction), and the first connecting portion 13 and the second connecting portion 23 are staggered front and back in a direction perpendicular to the installation direction. In other words, the first connecting portion 13 and the second connecting portion 23 can be staggered up and down or left and right, that is, in a left-right offset manner.

[0079] The third connecting member 30 is disposed between the first connecting member 10 and the second connecting member 20 and extends backward, and has an engaging hole 31. The first connecting portion 13 and the second connecting portion 23 are both inserted into the engaging hole 31, whereby the first connecting member 10, the second connecting member 20, and the third connecting member 30 are engaged with each other. In the first embodiment, the third connecting member 30 is inserted between the first building material plate body A1 and the second building material plate body A2, and has a pin hole 32 located between the first building material plate body A1 and the second building material plate body A2, so that a pin can be further used to strengthen the connection with the first building material plate body A1 and the second building material plate body A2; however, this is not limited in other embodiments. And, in the first embodiment, the pin hole 32 is an elongated hole, so that the position can be adjusted left and right, but it can also be a round hole.

[0080] In addition, in the first embodiment, after the third connecting member 30 extends backward, it is bent upward and extends to form an L-shaped plate body, and a through hole 33 is formed on the vertical section of the L-shaped plate body, so that it can be directly fixed to the wall A3 by fixing members such as screws. And the through hole 33 can be an elongated hole extending up and down or left and right, whereby the position fixed to the wall A3 can be adjusted. However, this is not limited in other embodiments. For example, please refer to Figure 4 and Figure 5, in the second embodiment, the third connecting member 30A can also be merely a flat plate body extending rearward, and is formed with a perforation 33A, and then combined with an additional L-shaped iron piece to be fixed to the wall A3. And in this case, the perforation 33A can be a long hole extending in the front-back or left-right direction, whereby the front-back or left-right relative position between the third connecting member 30A and the L-shaped iron piece can be adjusted. That is to say, in the three-piece embodiment, the third connecting member 30 can be directly fixed to the wall A3 in an L shape, or be a flat plate body and then indirectly fixed to the wall A3 through the L-shaped iron piece.

[0081] Furthermore, in the first embodiment, the first flat plate portion 11 has a first insert slot notch 111, and the first insert slot notch 111 is formed on the same edge of the first flat plate portion 11 as the first connecting portion 13. The first insert slot notch 111 deviates from the center of the first flat plate portion 11 in the left-right direction, and the deviating position is symmetric with the first connecting portion 13 with respect to the center of the first flat plate portion 11, and the first insert slot notch 111 is recessed in a direction opposite to the protruding direction of the first connecting portion 13. The second flat plate portion 21 has a second insert slot notch 211, and the second insert slot notch 211 is formed on the same edge of the second flat plate portion 21 as the second connecting portion 23. The second insert slot notch 211 deviates from the center of the second flat plate portion 21 in the left-right direction, and the deviating position is symmetric with the second connecting portion 23 with respect to the center of the second flat plate portion 21, and the second insert slot notch 211 is recessed in a direction opposite to the second connecting portion 23. The first connecting portion 13 passes through the engaging hole 31 and is inserted into the second insert slot notch 211, and the second connecting portion 23 passes through the engaging hole 31 and is inserted into the first insert slot notch 111. In other words, in the first embodiment, the first connecting member 10 and the second connecting member 20 are actually two identical components mirror-engaged with each other. However, in other left-right offset structures, this is not limited thereto, and the first insert slot notch 111 and the second insert slot notch 211 may not be provided. In this case, the first connecting portion 13 does not pass through the engaging hole 31 and abuts against the edge of the second flat plate portion 21, and the second connecting portion 23 does not pass through the engaging hole 31 and abuts against the edge of the first flat plate portion 11.

[0082] Please refer to Figure 4 , Figure 5 and Figure 6 , the second embodiment of the present invention is also a three-piece type like the first embodiment, but adopts an eight-character piece with a central single jack type. The structure of the second embodiment is basically the same as that of the first embodiment, and the differences are as follows.

[0083] In the second embodiment, the first flat portion 11A of the first connecting member 10A includes a main body portion 110A and a recessed portion 14A. The main body portion 110A and the second flat portion 21A are located at the same position in the installation direction, and the first engaging portion is formed on the main body portion 110A. The recessed portion 14A is connected to the main body portion 110A, deviates from the main body portion 110A in the installation direction (backward), and a front-back step difference is formed between the recessed portion 14A and the main body portion 110A. Specifically, the recessed portion 14A is bent backward at the bottom edge of the main body portion 110A and then bent downward. The whole is still parallel to the main body portion 110A but retreats backward from the first building material plate body A1 by a distance. The first connecting portion 13A is a tab protruding from the edge of the recessed portion 14A and is inserted into the engaging hole 31A. The second connecting portion 23A is a tab protruding from the edge of the second flat portion 21A and is inserted into the engaging hole 31A. The first connecting portion 13A and the second connecting portion 23A are staggered in the front-back direction in the installation direction, and the first connecting portion 13A and the second connecting portion 23A are located at the same position in the direction perpendicular to the installation direction; that is, the first connecting portion 13A and the second connecting portion 23A are located at the same position in the up-down direction or the left-right direction, and the first connecting portion 13A and the second connecting portion 23A are staggered in the front-back direction, that is, a central single jack type. That is to say, in the second embodiment, the width of the engaging hole 31A is equal to the width of one tab but the depth is equal to the thickness of two tabs. On the contrary, in the first embodiment, the width of the engaging hole is equal to the width of two tabs but the depth is equal to the thickness of one tab. Due to the front-back step difference of the recessed portion 14A, the first connecting portion 13A and the second connecting portion 23A can be staggered in the front-back direction, and at the same time, the main body portion 110A of the first flat portion 11A and the second flat portion 21A can still maintain the same degree of adjacency or abutment to the first building material plate body A1 and the second building material plate body A2. However, in other embodiments, there may be no main body portion 110A and recessed portion 14A, and the first flat portion 11A is a flat body formed by bending a continuous portion. In this case, when the first connecting portion 13A and the second connecting portion 23A are staggered in the front-back direction, the first flat portion 11A and the second flat portion 21A are also staggered in the front-back direction. In other words, the first flat portion 11A is slightly away from the first building material plate body A1.

[0084] In addition, in the second embodiment, the first building material plate body A1 has two fitting grooves A11, and two openings A111 are formed on the edges of the two fitting grooves A11 of the first building material plate body A1; in a cross-section perpendicular to the extending direction of the two fitting grooves A11, the two fitting grooves A11 are in a V-shape. The first engaging portion 12A includes two engaging pieces 121A. The two engaging pieces 121A are formed on the first flat plate portion 11A and are arranged left and right. The two engaging pieces 121A are parallel to the up and down direction, and extend obliquely backward (forward) and toward each other. The shapes of the two engaging pieces 121A match the shapes of the two fitting grooves A11, so that the two engaging pieces 121A can enter the two fitting grooves A11 through the two openings A111. In other words, the two engaging pieces 121A present a V-shape in a horizontal cross-section, and this V-shape does not change due to the up and down movement of the cross-section, that is, the V-shaped piece structure. The two engaging pieces 121A can be fitted into the V-shaped grooves formed on the back of the first building material plate body A1, and can enter the V-shaped grooves from the lower openings, thereby preventing the first building material plate body A1 from tipping forward and detaching; and, planting bar glue can be filled into the V-shaped grooves to strengthen the fixation. Furthermore, in the second embodiment, the third connecting member 30A only extends horizontally backward and does not bend upward anymore, so that an additional L-shaped iron piece can be used to fix the third connecting member 30A on the wall A3.

[0085] Please refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , the third embodiment of the present invention is a two-piece type, and a flat conical piece with double notches on both sides is adopted. The third embodiment only includes the first connecting member 10B and the second connecting member 20B and does not include the third connecting member, that is, a two-piece type. And, in the third embodiment, the structures of the first connecting member 10B and the second connecting member 20B are basically the same as the basic structures of the second embodiment, the difference being that the second connecting member 20B includes a fixed plate portion 24B in the third embodiment to replace the third connecting member. The fixed plate portion 24B is bent and formed at the edge of the second flat plate portion 21B and extends backward. The second connecting portion 23B is formed on the fixed plate portion 24B and has two connecting notches 231B, and the two connecting notches 231B are respectively formed on both side edges of the fixed plate portion 24B in the direction (up and down direction or left and right direction) perpendicular to the installation direction. And the first connecting portion 13B in the third embodiment is that two inserting pieces protrude from the edge of the retracting portion 14B of the first flat plate portion and are respectively inserted into the two connecting notches 231B. Thereby, the two inserting pieces sandwich the fixed plate portion 24B left and right, and the two connecting notches 231B limit the two inserting pieces front and back, and the first connecting portion 13B is engaged with the second connecting portion 23B, that is, the double-notch type on both sides.

[0086] In the third embodiment, the fixed connection plate portion 24B extends horizontally backward and is fixed to an additional L-shaped iron piece through a perforation and screw nuts, and is fixed to the wall A3 through the additional L-shaped iron piece. However, in other embodiments, the end of the fixed connection plate portion 24B can also be bent upward and extended with perforations, so that it can be directly fixed to the wall A3 like the third connecting member in the first embodiment.

[0087] In addition, in the third embodiment, the first building material plate body A1 has a plate body coupling hole A12. The plate body coupling hole A12 is a two-stage hole, that is, the plate body coupling hole A12 includes an inner engaging section A121 and an outer penetrating section A122 that are connected and communicate along the installation direction. The cross-sectional area of the inner engaging section A121 is larger than that of the outer penetrating section A122. The first coupling portion 12B includes an inner penetrating portion 121B and an outer engaging portion 122B. The inner penetrating portion 121B is formed on the first flat plate portion 11B and extends in the reverse installation direction (forward). The shape of the inner penetrating portion 121B matches the shape of the outer penetrating section A122 of the plate body coupling hole A12, so that the inner penetrating portion 121B can be movably received in the outer penetrating section A122 up and down. The outer engaging portion 122B is formed at one end of the inner penetrating portion 121B away from the first flat plate portion 11B and extends and expands left and right. The cross-sectional area of the outer engaging portion 122B is larger than that of the inner penetrating portion 121B; the outer engaging portion 122B is used to penetrate into the plate body coupling hole A12 of the first building material plate body A1; the shape of the outer engaging portion 122B matches the shape of the outer penetrating section A122 of the plate body coupling hole A12, so that the outer engaging portion 122B can pass through the outer penetrating section A122; the shape of the outer engaging portion 122B matches the shape of the inner engaging section A121 of the plate body coupling hole A12, so that the outer engaging portion 122B can be movably received in the inner engaging section A121 up and down; when the outer engaging portion 122B moves upward in the inner engaging section A121, the outer engaging portion 122B is restricted by the outer penetrating section A122 and cannot exit the plate body coupling hole A12. By means of the inner penetrating portion 121B and the outer engaging portion 122B, the first coupling portion 12B can penetrate into the two-stage hole on the back surface of the first building material plate body A1 to hang the first building material plate body A1, that is, a flat cone piece structure. And, planting bar glue can be filled in the two-stage hole to strengthen the fixation.

[0088] Please refer to Figure 11 , the fourth embodiment of the present invention is also two-piece, and uses a flat cone piece with a T-shaped jack. The structure of the fourth embodiment is basically the same as that of the third embodiment, and the differences are as follows.

[0089] The second connecting portion 23C has a clamping hole 231C and a clamping notch 232C. The clamping notch 232C is recessed in the circumferential edge of the clamping hole 231C in the reverse installation direction (forward). In the direction perpendicular to the installation direction (such as the up-down direction or the left-right direction), the distance between the two ends of the clamping hole 231C is greater than the distance between the two ends of the clamping notch 232C. The first connecting portion 13C includes a first narrow portion 131C and a first wide portion 132C. The first narrow portion 131C is connected to the edge of the retracted portion 14C of the first flat plate portion and passes through the clamping notch 232C. The first wide portion 132C is connected to one end of the first narrow portion 131C away from the retracted portion 14C. In the direction perpendicular to the installation direction (such as the up-down direction or the left-right direction), the distance between the two ends of the first wide portion 132C is less than the distance between the two ends of the clamping hole 231C and greater than the distance between the two ends of the clamping notch 232C. That is to say, the first connecting portion 13C is a T-shaped sheet, and the second connecting portion 23C is a T-shaped hole. After the first wide portion 132C passes through the clamping hole 231C, the first narrow portion 131C can move to pass through the clamping notch 232C. Thus, the first wide portion 132C with a larger width will be clamped by the clamping notch 232C with a smaller width, so that the first connecting member 10C cannot be directly separated from the second connecting member 20C upward, that is, the T-type socket type.

[0090] The three preferred structures of the keyhole, the flat cone sheet and the figure-eight sheet for combining with the first building material plate body A1 and the second building material plate body A2, as well as the four combination methods between the central single socket type, the T-type socket type, the double notch type on both sides and the left-right dislocation type of the connecting members, are all described in the above first to fourth embodiments. These structures can be combined arbitrarily and can all be applied to two-piece or three-piece, with a total of twenty-four matching methods.

[0091] For example, if the T-type socket type is adopted in the three-piece type, then:

[0092] The third connecting member has a clamping hole and a clamping notch. The clamping notch is recessed in the circumferential edge of the clamping hole in the direction reverse to the installation direction. In the direction perpendicular to the installation direction, the distance between the two ends of the clamping hole is greater than the distance between the two ends of the clamping notch. The first connecting portion is a tab protruding from the edge of the first flat portion and includes a first narrow portion connected to the edge of the first flat portion. The first narrow portion is inserted into the clamping notch. A first wide portion is connected to one end of the first narrow portion away from the first flat portion. In the direction perpendicular to the installation direction, the distance between the two ends of the first wide portion is less than the distance between the two ends of the clamping hole and greater than the distance between the two ends of the clamping notch. The second connecting portion is a tab protruding from the edge of the second flat portion and includes a second narrow portion connected to the edge of the second flat portion. The second narrow portion is inserted into the clamping notch. A second wide portion is connected to one end of the second narrow portion away from the second flat portion. In the direction perpendicular to the installation direction, the distance between the two ends of the second wide portion is less than the distance between the two ends of the clamping hole and greater than the distance between the two ends of the clamping notch. The first connecting portion and the second connecting portion are staggered in the installation direction. And a recessed portion can be further combined therewith to keep the first flat portion in abutment or adjacent while staggering front and back.

[0093] If the two-side double-notch type is adopted in the three-piece type, then:

[0094] The third connecting member has two connecting notches which are respectively formed on the two side edges of the third connecting member in the direction perpendicular to the installation direction. The first connecting portion is two tabs protruding from the edge of the first flat portion and are respectively inserted into the two connecting notches. The second connecting portion is two tabs protruding from the edge of the second flat portion and are respectively inserted into the two connecting notches. The first connecting portion and the second connecting portion are staggered in the installation direction. And a recessed portion can be further combined therewith to keep the first flat portion in abutment or adjacent while staggering front and back.

[0095] If the central single-jack type is adopted in the two-piece type, then:

[0096] The second connecting member includes a fixed plate portion bent at the edge of the second flat portion; the second connecting portion is formed on the fixed plate portion and has a clamping hole; the first connecting portion is a tab protruding from the edge of the first flat portion and is inserted into the clamping hole. And a recessed portion can be further combined therewith to keep the first flat portion in abutment or adjacent while staggering front and back.

[0097] Please refer to Figure 12, the basic structure of the fifth embodiment of the present invention is the same as that of the second embodiment. The difference is that in the fifth embodiment, the first connecting member 10D includes a plurality of first engaging portions 12D. One of the first engaging portions 12D is a perforation formed through the first flat plate portion 11D and is used for a first fixing member to pass through. And, the second connecting member 20D includes a plurality of second engaging portions 22D. One of the second engaging portions 22D is a perforation formed through the second flat plate portion 21D and is used for a second fixing member to pass through.

[0098] Please refer to Figure 13 , the basic structure of the sixth embodiment of the present invention is the same as that of the third embodiment. The difference is that in the sixth embodiment, the first connecting member 10E includes a plurality of first engaging portions 12E. One of the first engaging portions 12E is a perforation formed through the first flat plate portion 11E and is used for a first fixing member to pass through. And, the second connecting member 20E includes a plurality of second engaging portions 22E. One of the second engaging portions 22E is a perforation formed through the second flat plate portion 21E and is used for a second fixing member to pass through.

[0099] Please refer to Figure 14 , the basic structure of the seventh embodiment of the present invention is the same as that of the fourth embodiment. The difference is that in the seventh embodiment, the first connecting member 10F includes a plurality of first engaging portions 12F. One of the first engaging portions 12F is a perforation formed through the first flat plate portion 11F and is used for a first fixing member to pass through. And, the second connecting member 20F includes a plurality of second engaging portions 22F. One of the second engaging portions 22F is a perforation formed through the second flat plate portion 21F and is used for a second fixing member to pass through.

[0100] In summary, whether in the two-piece or three-piece type, the first connecting member and the second connecting member can both have two engaging portions. And one of the engaging portions is a long perforation (i.e., a keyhole structure) the same as that of the first embodiment, while the other can be a flat cone piece or an eight-character piece. In addition, the forms of the two engaging portions can all be applied to the four engaging methods of the central single jack type, the T-shaped jack type, the double notch type on both sides, and the left-right dislocation type.

[0101] The advantages of the present invention are as follows. In the three-piece embodiment, the first connecting member 10 and the first building material plate body A1 can be assembled first, and the second connecting member 20 and the second building material plate body A2 can be assembled first. When arriving at the construction site, only the third connecting member 30 needs to be combined on the wall, and then the two building material plate bodies A1 and A2 can be quickly inserted onto the third connecting member 30 through the first connecting member 10 and the second connecting member 20. In the two-piece embodiment, the first connecting member 10 and the first building material plate body A1 can be assembled first. When arriving at the construction site, only the second connecting member 20 needs to be combined on the wall and with the second building material plate body A2, and then the first building material plate body A1 can be quickly inserted onto the second connecting member 20 through the first connecting member 10. The present invention can be pre-installed thereby, greatly reducing the operation difficulty at the construction site, and facilitating the operation even in a narrow gap.

[0102] Moreover, in the three-piece embodiment, it is more convenient to finely adjust the position of the first building material plate body A1 through the first connecting member 10 and the third connecting member 30, and to finely adjust the position of the second building material plate body A2 through the second connecting member 20 and the third connecting member 30. In the two-piece embodiment, it is more convenient to finely adjust the position of the first building material plate body A1 through the first connecting member 10 and the second connecting member 20.

[0103] Therefore, the present invention is not limited by a narrow gap, and can simplify the construction method and speed up the construction speed.
