Description

Technical Field

[0001] The present invention relates to the technical field of back bolt anchoring for stone curtain walls, and more specifically, to a strip-shaped back bolt anchoring structure, a stone back bolt anchoring system, and an anchoring method. Background Art

[0002] The existing stone curtain wall back bolt anchoring system has the following problems: 1. The back bolt hole is an inverted conical hole, and the processing method is special. It is not easy to control the processing quality of the back bolt hole, and there is no reliable detection method after the back bolt hole is processed; 2. The force on the stone plate at the position where the back bolt connects the stone is the shear force on the stone around the back bolt hole, and the length of the shear surface of the stone is short; 3. The connection between the back bolt and the hanging piece is a round hole, and the hanging piece can rotate around the back bolt, which easily leads to unreliable on-site installation; 4. The back bolt hole on the stone is small. If there are loose holes in the stone at the processing position of the back bolt hole, it may cause anchoring failure; 5. When the stone back bolt parts and the hanging pieces are produced by different manufacturers, the procurement and assembly are also more troublesome.

[0003] In view of this, the present application is specifically proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing anchoring of the hanging piece and the stone using the inverted conical back bolt hole structure has problems such as a small shear surface and unreliable anchoring. The purpose is to provide a strip-shaped back bolt anchoring structure that can use the clamping force to expand the expansion part outward so as to be stuck into the groove processed in the stone, realizing the anchoring of the hanging piece and the stone.

[0005] The present invention also provides a strip-shaped stone back bolt anchoring system, which uses the structure of the dovetail groove and the outward expansion of the expansion part under pressure to realize the anchoring of the hanging piece and the stone. Compared with the inverted conical back bolt hole, the dovetail groove of the present invention is more convenient to process, and the processing quality is reliable. At the same time, the strip-shaped back bolt makes the shear surface of the stone larger, the force is better, and it is not easy to cause anchoring failure.

[0006] The present invention also provides an anchoring method for the stone and the hanging piece.

[0007] The present invention is realized through the following technical solutions:

[0008] A strip-shaped back bolt anchoring structure includes a strip-shaped support piece and an expansion part; the expansion part is used to be arranged between the support piece and the hanging piece, and the expansion part can generate an outward expansion deformation in width when subjected to the clamping force of the support piece and the hanging piece.

[0009] In the back bolt structure of the present invention, the expansion part can generate an outward expansion deformation when subjected to the clamping force, so that it can be stuck into the groove processed in the stone. Compared with the existing back bolt and the inverted conical back bolt hole anchoring structure, the shear surface of the stone is larger, the force is better and more uniform, avoiding the failure of the entire anchoring structure due to encountering some weak parts. At the same time, the strip-shaped back bolt can prevent the rotation of the hanging piece and the stone after connection.

[0010] It also includes screws and nuts. Screw holes are provided on both the support member and the expansion member. The screw sequentially passes through the screw holes of the support member, the screw holes of the expansion member, and the screw holes of the hanging member and is connected to the nut. By tightening the nut, the support member and the hanging member can clamp and expand the expansion member. In the present invention, the connection between the back bolt and the hanging member is realized by tightening the screw and the nut, and the clamping force of the expansion member is provided. It is more convenient to operate, and at the same time, the provided clamping force is more stable and the connectivity is better.

[0011] The support member is made of aluminum alloy, the expansion member is made of stainless steel or aluminum alloy, and the screws and nuts are also made of stainless steel, so as to ensure the strength of the back bolt structure.

[0012] One side of the expansion member close to the support member has a card slot. The width of the support member gradually increases along the direction away from the expansion member. The support member can be inserted into the card slot to expand the expansion member in the width direction.

[0013] The cross section of the expansion member is in an "M" shape. The side where the middle convex rib of the "M" - shaped expansion member is located faces the support member. When the support member and the hanging member squeeze and clamp the expansion member, the support member squeezes the middle convex rib of the "M" to make it gradually flat, and the two side plates of the expansion member expand outwards for being clamped into the groove of the stone.

[0014] Both the screw and the nut are provided with two. Two screw holes are also provided on both the support member and the expansion member, having two fixed nodes. In this way, when the back bolt is installed with the hanging member, rotation can be avoided.

[0015] One side of the support member away from the expansion member has a groove, and the depth of the groove is the same as the thickness of the screw head. After the support member and the expansion member are placed into the groove of the stone, the end face of the screw head and the end face of the support member can be flush and closely attached to the groove wall, which can provide a better and more stable supporting force for the operation of tightening the nut.

[0016] A strip - shaped stone back - bolt anchoring system includes a stone, a support member, an expansion member, and an aluminum alloy hanging member. A strip - shaped dovetail groove is provided on the back of the stone. Screw holes are provided on the support member, the expansion member, and the hanging member. The screw sequentially passes through the screw holes of the support member, the screw holes of the expansion member, and the screw holes of the hanging member and is connected to the nut. The support member and the expansion member are arranged in the dovetail groove. By tightening the nut, the aluminum alloy hanging member and the support member clamp the expansion member, and the two side edges of the expansion member expand outwards in the width direction and are clamped into the dovetail groove.

[0017] The present invention realizes the anchoring of the aluminum alloy hanging piece and the stone plate by using the dovetail groove and the expanding structure of the back bolt expansion piece. First, the dovetail groove is convenient to process, and its contour is mainly ensured by the shape of the processing tool, with reliable quality. Second, the processed dovetail groove is convenient to detect, which can facilitate the control of the processing quality of the groove. Finally, the combination of the dovetail groove with a strip structure and the strip back bolt can make the shearing surface of the stone larger and the force better, and at the same time, the hanging piece and the stone will not rotate after connection.

[0018] A method for anchoring a stone and a hanging piece includes the following steps: 1) Drill a reverse taper milling cutter into the middle of the back of the stone, and then laterally mill a horizontal dovetail groove; 2) Connect the support piece and the expansion piece with a strip structure to the hanging piece by using screws and nuts; 3) Horizontally place one end where the support piece is located into the dovetail groove until the side wall of the support piece is closely attached to the wall surface of the dovetail groove, and tighten the nut to provide the extrusion force of the expansion piece towards the stone direction. The expansion piece moves towards the support piece direction, and the upper and lower edges of the expansion piece are respectively expanded in the up and down directions under the action of the support piece and thus are clamped into the stone dovetail groove.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] 1. A back bolt anchoring structure provided by an embodiment of the present invention can utilize the clamping force to expand the expansion piece and thus clamp it into the groove processed on the stone, realizing the stable anchoring of the hanging piece and the stone;

[0021] 2. A stone back bolt anchoring system provided by an embodiment of the present invention is convenient to process the dovetail groove, and its contour is mainly ensured by the shape of the processing tool, with reliable quality. Second, the processed dovetail groove is convenient to detect, which can facilitate the control of the processing quality of the groove;

[0022] 3. A stone back bolt anchoring system provided by an embodiment of the present invention can make the shearing surface of the stone larger, the force better and more uniform by using a strip back bolt, avoiding the failure of the entire anchoring structure due to encountering some weak parts, and at the same time avoiding the rotation of the hanging piece;

[0023] / 4. A stone back bolt anchoring system provided by an embodiment of the present invention only needs to process a threaded hole on the hanging piece during use, which can realize the rapid assembly of the stone and the hanging piece, avoiding the situation of non - matching between the back bolt part and the hanging piece.
