Description

Dry-hanging piece with falling warning effect for building outer wall

Technical Field

The invention belongs to the field of building outer walls, and particularly relates to a dry hanging piece with a falling warning effect for a building outer wall.

Background

The back-bolt type connector is also called a dry hanging piece. The traditional wall surface sticking mode is not used any more in the decoration of the prior building wall surface, and the decorative stone is fixed on a fixed bracket which is welded and installed on the wall surface by using a back bolt type connecting piece; the back-bolt type connecting piece is utilized to hang ceramic tiles or stones on the wall surface, so that other decoration materials which are relatively complex in working procedures and have certain pollution to the environment are not needed in building decoration, and the body health of residents and constructors is ensured; meanwhile, after the ceramic tile or the stone is damaged, the ceramic tile or the stone can be conveniently replaced. However, the back-bolt type connector has the following problems:

firstly, as the back bolt type connecting piece is likely to be damaged and broken under long-time wind, rain and rain, the ceramic tiles or the stones connected with the damaged back bolt type connecting piece can fall from a high place without any sign, thereby forming certain potential safety hazard.

Secondly, if one of the whole row of decorative stones is damaged, when the damaged decorative stone needs to be replaced, because each decorative stone in the whole row of decorative stones is arranged next to each other in sequence, after the materials of the gap needing to be supplemented for the two adjacent decorative stones are removed, the space which can be replaced by a constructor is basically equal to the space of the damaged decorative stone. When the damaged decorative stone is taken down and replaced with a new decorative stone, since a space allowing the replacement by a constructor is substantially equal to a space of the damaged decorative stone, there is no additional operating space for an operator to manually place and adjust the new decorative stone, so that the entire row of decorative stones needs to be detached, then the new decorative stone is re-supplemented and arranged at the position of the damaged decorative stone, and finally the supplemented entire row of decorative stones is re-installed. Therefore, it is very troublesome to replace the damaged decorative stone with the conventional back-bolt-type connecting member, and it is necessary to design a novel back-bolt-type connecting member which can independently replace the damaged decorative stone without detaching the whole row of decorative stones.

Thirdly, if the pattern of one decorative stone in the whole row of decorative stones does not meet the decorative requirement and needs to be replaced, the original whole row of decorative stones needs to be completely detached to replace the decorative stone which does not meet the decorative requirement, the replacement is very troublesome, and the efficiency is very low.

The invention designs a dry hanging piece with a falling warning function for an outer wall of a building, and solves the problems.

All the rubber pads 68 of the present invention can be mounted as shown in fig. 24, and other mounting methods known in the art can be used.

The invention reasonably designs the outer diameter of the Y spring 22, so that the end part of the inclined plane of the A inner block 28 and the end part of the inclined plane of the B inner end cannot interfere with the Y spring 22 in the compression and reset processes of the Y spring 22.

The specific working process is as follows: the dry hanging piece of the invention is in an initial state when not being arranged on the decorative stone 12: as shown in fig. 21, the adjusting block 7 is not jacked up, the T-spring 72 is in a pre-tensioned state, the a outer block 34 is in sliding contact with the a push bar 46, the a outer spring 50 on the a outer block 34 is in a tensioned state, and the inclined end of the a inner block 28 passes through the a socket 39 and enters the fixed cylinder 23; the B inner block 29 is in sliding contact with the B push bar 55, the B outer spring 56 is in a natural state, and the inclined end of the B inner block 29 is positioned in the B socket 40; since the spring constant of T-spring 72 is greater than the spring constant of A-outer spring 50, T-spring 72 in its pre-tensioned state maintains A-outer spring 50 in its tensioned state. The A inner block 28 limits the sliding ring 21, the Y spring 22 is in a compressed state, and one end of the sleeve 20 facing the nut 19 penetrates out of the fixed cylinder 23. The end of the pull rope 10 far away from the washer 3 is fixedly connected with the rope ring 9 of the positioning strip 4. The square block 17 is attached to the inner end face of the opening of the square tube 18, the Z spring 16 is in a micro-pressure state, and the tube bottom of the square tube 18 with the rectangular teeth 14 is far away from the positioning strip 4.

The process of installing the dry hanging piece on the decorative stone 12 comprises the following steps: as shown in fig. 3, a back side of the decorative stone 12 is first drilled with a bolt hole 78 by a tool, and then one end of the back bolt 5 having the bit and the grommet 32 is inserted into the bolt hole 78. Since the two clamping strips 15 on the square tube 18 always clamp the positioning strip 4 in the middle, the sleeve 20 can be pressed by rotating the nut 19 by using a tool, the sleeve 20 presses the pressure-protecting ring 32, and the pressure-protecting ring 32 is expanded to fix the back bolt 5 in the bolt hole 78. In the method for mounting the dry hanging member of the present invention on the decorative stone 12 by the back bolt 5, after the back bolt 5 is fixed in the bolt hole 78 of the decorative stone 12, since the hanging member plate 8 is not mounted on the corner brace 1, the inner block 28 a still limits the sliding ring 21, and the Y spring 22 is still in a compressed state, only the relative displacement occurs between the sleeve 20 and the screw rod 25. In this state, the bottom of the square cylinder 18 with the rectangular teeth 14 still has a large distance from the positioning bar 4.

As shown in fig. 2 and 3, before the dry hanging piece of the invention is installed on the corner brace 1, firstly, the transverse plate of the corner brace 1 is fixed on the cross beam 13 by the bolt 2, the decorative stone 12 is manually held, then the gasket 3 fixedly connected with one end of the pull rope 10 on the dry hanging piece passes through the square hole 79 arranged on the vertical plate of the corner brace 1, and the gasket 3 is fixed on the transverse plate of the corner brace 1 by the bolt 2; thus, the dry hanging piece is connected with the corner connector 1 through the pull rope 10.

The flow of installing the dry hanging piece on the corner connector 1 is as follows: manually holding the decorative stone 12, and hanging the hanging plate 8 of the dry hanging piece on the decorative stone 12 on the vertical plate of the corner brace 1; the U-shaped plate 62 on the hanging plate 8 is completely clamped on the top end of the vertical plate of the corner connector 1, and the lower end of the hanging plate 8 is attached to the side face of the vertical plate of the corner connector 1 in an extruding mode.

As shown in fig. 22, when the top end of the vertical plate of the corner connector 1 jacks up the adjusting block 7 in the U-shaped plate 62 to the extreme position, the square plate 71 moving along with the adjusting block 7 stretches the T-shaped spring 72; the adjusting block 7 drives the X rack 66 to move upwards through the connecting rod 63; the upward X rack 66 drives the B rack 54 and the B pushing bar 55 to move towards the B outer block 36 through the B gear 53, the B pushing bar 55 pushes the B outer block 36 to move towards the fixed cylinder 23, the B outer spring 56 is stretched, and the B outer block 36 pushes the B inner block 29 to be inserted into the fixed cylinder 23 from the B socket 40 through the B inner spring 35; the beveled end of the B inner block 29 now just protrudes through the B socket 40, and the side wall of the B inner block 29 facing the a inner block 28 does not protrude through the B socket 40, and the side wall of the B inner block 29 facing away from the a inner block 28 protrudes through the B socket 40. The upward X rack 66 drives the A rack 47 and the A push bar 46 to move away from the A outer block 34 through the A gear 45; under the reset action of the A outer spring 50, the A outer block 34 pulls the A inner block 28 to move towards the A push bar 46 through the A inner guide block 51; when the A outer block 34 pulls the A inner block 28 to move to the limit position in the direction of the A push bar 46 through the A inner guide block 51, the A outer block 34 is still in sliding contact with the A push bar 46, the A outer spring 50 restores to the natural state, and one end of the A inner block 28 with the inclined surface just completely enters the A socket 39. Because all the outer wall surfaces of the A inner block 28 and the two side surfaces of the sliding ring 21 are subjected to smoothing treatment, when the sliding ring 21 has large extrusion force on the side surface of the A inner block 28, the A inner block 28 can still slide from the side surface of the sliding ring 21 with small force; the restoring force of the A outer spring 50 ensures that the A outer block 34 can pull the A inner block 28 to move towards the A push bar 46 through the A inner guide block 51.

Since the beveled end of the a inner block 28 just fully enters the a socket 39, the a inner block 28 no longer provides a stop for the slide ring 21. Under the action of the return of the Y-shaped spring 22 and the action of manually controlling the decorative stone 12 by human assistance, the sliding ring 21 moves towards the bottom of the fixed cylinder 23, the sliding ring 21 pushes the nut 19, the screw 25 and the attached decorative stone 12 to gradually approach towards the vertical plate of the corner brace 1 through the sleeve 20, and the distance between the bottom of the square cylinder 18 with the rectangular teeth 14 and the positioning strip 4 gradually decreases. During the process, the decorative stone 12 can be manually controlled to be finely adjusted up and down to ensure that the decorative stone 12 can be aligned with the whole row of the decorative stone 12; when the decorative stone 12 is manually controlled to be vertically adjusted, the decorative stone 12 drives the sliding block 26 to slide in the square sliding groove 27 of the hanging plate 8 through the back bolt 5.

When the sliding ring 21 moves to the middle position of the A inner block 28 and the B inner block 29, the plurality of rectangular teeth 14 at the bottom of the square tube 18 are meshed with the plurality of rectangular teeth 14 on the positioning strip 4 at the moment, so that the back bolt 5 is limited in the up-and-down moving direction along the square sliding groove 27; if a plurality of rectangle teeth 14 of square tube 18 bobbin base and a plurality of rectangle teeth 14 on the location strip 4 take place the dislocation and when unable mutual interlock, but the fine setting from top to bottom of manual control decoration stone material 12 for the decoration stone material 12 drives square tube 18 on the back of the body bolt 5 and finely tunes from top to bottom, thereby just can make a plurality of rectangle teeth 14 of square tube 18 bobbin base fine tuning to with a plurality of rectangle teeth 14 on the location strip 4 position that take place the interlock, just so can interlock a plurality of rectangle teeth 14 of square tube 18 bobbin base and a plurality of rectangle teeth 14 on the location strip 4 each other, thereby with the back of the body bolt 5 spacing on the direction of reciprocating along direction spout 27.

When the decorative stone 12 is finely adjusted up and down, the decorative stone 12 drives the sliding block 26 to move up and down in the square sliding groove 27 through the fixed cylinder 23 in the back bolt 5, the fixed cylinder 23 drives the A outer block 34 and the B inner block 29 to move up and down through the A square sleeve 41 and the B square sleeve 42 in the process, the A outer block 34 and the B outer block 36 which move up and down are always in sliding fit with the A push strip 46 and the B push strip 55 respectively, and the A push strip 46 can push the A outer block 34 at any time or the B push strip 55 can push the B outer block 36 at any time.

After the plurality of rectangular teeth 14 at the bottom of the square cylinder 18 are mutually meshed with the plurality of rectangular teeth 14 on the positioning strip 4, adjusting hand strength to enable the decorative stone 12 to be close to the corner connector 1, and observing whether the decorative stone is aligned with the mounted decorative stone on the periphery; if the decorative stone is not aligned, the decorative stone is pulled outwards again, so that the plurality of rectangular teeth 14 at the bottom of the square tube 18 are not meshed with the plurality of rectangular teeth 14 on the positioning strip 4; then moving the decorative stone upwards or downwards, and meshing the plurality of rectangular teeth 14 at the bottom of the square cylinder 18 with the plurality of rectangular teeth 14 on the positioning strip 4 again; and then, approaching the decorative stone to the corner connector 1, and observing whether the decorative stone is aligned with the mounted decorative stone on the periphery. After the decorative stone 12 being installed is aligned with the installed decorative stone 12, the outward pulling force on the decorative stone 12 is removed. Since the alignment confirmation of the decorative stone is the alignment confirmed after the engagement of the rectangular teeth 14, the alignment is accurate when the pulling force to the decorative stone 12 is completely removed. After the outward pulling force on the decorative stone 12 is removed, under the reset action of the Y spring 22, the sliding ring 21 located at the middle position of the A inner block 28 and the B inner block 29 continues to move towards the bottom of the fixed cylinder 23, and the sliding ring 21 pushes the nut 19, the screw 25 and the attached decorative stone 12 to gradually approach towards the vertical plate of the corner brace 1 through the sleeve 20. Since the elastic coefficient of the Y spring 22 is larger than that of the Z spring 16 in the present invention, the block 17 on the screw 25 can move in the square tube 18 toward the positioning bar 4 to compress the Z spring 16. When the sliding ring 21 presses the long inclined surface 30 of the B inner block 29, the B inner block 29 retracts into the B inner groove 58 of the B outer block 36, the B inner spring 35 is compressed, and the inclined surface end of the B inner block 29 is pressed into the B socket 40; after the sliding ring 21 passes over the B inner block 29, under the reset action of the B inner spring 35, the B inner block 29 protrudes from the B inner groove 58 again, and the inclined end in the B inner groove protrudes out of the B socket 40 again. As shown in fig. 23, when the sliding ring 21 moves to the bottom of the fixed cylinder 23, the surface of the sliding ring 21 connected with the Y spring 22 is attached to the side surface of the B inner block 29 where the short inclined surface 31 is located, and the B inner block 29 limits the sliding ring 21 between the bottom of the fixed cylinder 23 and the B inner block 29; at the moment, the Y spring 22 is still in a compressed state, the Z spring 16 is extruded into a maximum compressed state by the square block 17, and the compressed Z spring 16 enables the plurality of rectangular teeth 14 on the square tube 18 to be in dead and dead occlusion with the plurality of rectangular teeth 14 on the positioning strip 4, so that the square tube 18 and the positioning strip 4 are firmly limited, and the back bolt 5 is ensured to be firmly limited on the hanging plate 8. When the slip ring 21 moves to the bottom of the fixed cylinder 23, the decorative stone 12 does not move towards the corner brace 1 any more, and the operation of mounting the decorative stone 12 and the dry hanging piece on the corner brace 1 is finished; the newly installed decorative stone 12 is coplanar with the installed decorative stone 12; the pull cord 10 is in a completely relaxed state at this time. Finally, the sealing strips can be installed on the gaps between two adjacent decorative stones 12.

The process of installing the dry hanging pieces on the whole decorative stone 12, the process of installing the corner brace 1 on the cross beam 13 and the process of installing the dry hanging pieces on the corner brace 1 are carried out; particularly, in the process of installing the dry hanging piece on the corner brace 1, if the decorative stone 12 to be installed is to be installed at the middle position of two installed decorative stones 12, the size of the middle position is basically equal to that of the decorative stone 12 to be installed; because the dry hanging piece is arranged on the corner brace 1, when the decorative stone 12 to be arranged is not coplanar with the arranged decorative stone 12, the decorative stone 12 to be arranged is gradually close to the corner brace 1 until the decorative stone 12 to be arranged is coplanar with the arranged decorative stone 12, which means that the decorative stone 12 is arranged, the two sides of the decorative stone 12 are provided with spaces for constructors to manually control the decorative stone 12 in an auxiliary manner or adjust the decorative stone 12 in the process that the decorative stone 12 is gradually close to the corner brace 1.

When the pendant plate 8 in the dry pendant is damaged and broken under long-time wind, rain and rain, the pendant plate 8 can fall off from the corner brace 1; because one end of the pull rope 10 is connected with the corner brace 1, the falling hanging plate 8 can still be connected with the corner brace 1, the decorative stone 12 on the hanging plate 8 can not fall from a high place without any indication, and certain potential safety hazards are avoided. In addition, because the pendant board 8 that drops is held by the stay cord 10 and can't drop, then the pendant board 8 that is held by the stay cord 10 and the subsidiary decorative stone 12 are held and obviously have different from normal decorative stone 12 to can carry out the warning effect of certain degree, let constructor's naked eye can observe unusual decorative stone 12, thereby can change unusual decorative stone 12.

When one of the whole row of decorative stones 12 is damaged, the dry hanging piece of the invention does not need to completely disassemble the original whole row of decorative stones 12 to replace the decorative stones 12, but only needs to replace the damaged decorative stones 12 alone. The process is as follows: the damaged decorative stone 12 is completely crushed, so that a constructor can have enough space for manual operation, and the constructor can manually disassemble the pendant plate 8 in the dry pendant from the corner brace 1; and manually removing the bolt 2 to remove the washer 3 at one end of the pull rope 10 from the corner brace 1, and releasing the soft connection between the dry hanging piece and the corner brace 1, thereby finishing the operation of completely removing the dry hanging piece from the corner brace 1. When a new decorative stone 12 needs to be reinstalled, the specific installation process can refer to the process of installing the dry hanging pieces on the decorative stone 12, the process of installing the corner brace 1 on the cross beam 13, and the process of installing the dry hanging pieces on the corner brace 1.

When the pattern of one decorative stone 12 in the whole row of decorative stones 12 is required to be replaced without meeting the decorative requirement, the sealing strips around the decorative stone 12 to be replaced are removed by a tool, then the tool is inserted into the gap between two adjacent decorative stones 12, and then the decorative stone 12 to be replaced is moved upwards by a small amplitude. Because the square tube 18 in the back bolt 5 is fixed with the positioning strip 4 on the hanging plate 8 in a meshing manner by the rectangular teeth 14, the decorative stone 12 to be replaced can move the hanging plate 8 upwards from the corner brace 1 by a small amplitude through the back bolt 5. Then under the reset action of the T-shaped spring 72, the adjusting block 7 moves downwards by a small amplitude relative to the U-shaped plate 62 in the hanging plate 8; the adjusting block 7 drives the X rack 66 to move downwards in a small range through the connecting rod 63. The X rack 66 moving downwards in a small amplitude drives the A rack 47 and the A push bar 46 to move towards the A outer block 34 in a small amplitude through the A gear 45, the A push bar 46 pushes the A outer block 34 to move towards the fixed cylinder 23 in a small amplitude, the A outer spring 50 is stretched, and the A outer block 34 pushes the A inner block 28 to be inserted into the fixed cylinder 23 from the A socket 39 through the A inner spring 33; the beveled end of the a inner block 28 now exits the a socket 39 a by a small amount. The X rack 66 moving downwards in a small amplitude drives the B rack 54 and the B push bar 55 to move in a small amplitude in a direction away from the B outer block 36 through the B gear 53; under the reset action of the B outer spring 56, the B outer block 36 pulls the B inner block 29 through the B inner guide block 59 to move in the direction of the B push bar 55 by a small amplitude, the side wall surface at the end of the short inclined surface 31 of the B inner block 29 can completely enter the B socket 40, and at the moment, the B inner block 29 cannot limit the sliding ring 21.
