Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass curtain wall installation, and particularly relates to a glass curtain wall glass fixing device. BACKGROUND

[0002] The glass curtain wall is a novel and beautiful building wall decoration method, which refers to the building envelope structure or decoration structure which can have a certain displacement capacity relative to the main structure and does not share the action of the main structure. According to different factors such as glass type, installation method and supporting structure, the glass curtain wall can be divided into the following five types: full glass curtain wall, glass brick curtain wall, point connection type glass curtain wall, frame type glass curtain wall and cable structure glass curtain wall. The point connection type glass curtain wall is composed of a glass panel, a point support device and a supporting structure, and has the stability of steel structure, the lightness of glass and the precision of machinery.

[0003] The glass of the point type glass curtain wall is fixed by a stainless steel claw piece penetrating through a pre-drilled hole on the glass, and then the glass is bonded to the frame structure by using structural adhesive. The support of the glass is mainly connected to the supporting structure by the metal connection piece. The stress system of the point type glass curtain wall is not on the frame structure compared with the general glass curtain wall. Therefore, the cooperation between the metal connection piece and the glass needs to be precise and accurate to achieve strong support effect on the glass. When the glass is punched, a slight error is inevitably generated in the position of the mounting hole on the glass. The conventional fixed connection piece cannot adjust the installation position according to the position of the mounting hole, which will lead to an increase in the scrap rate of single glass in the glass curtain wall. Since the area of the glass in the curtain wall is large and the manufacturing and processing cost is also very high, the glass processing cost will be further increased if the single glass is scrapped due to a slight error. At the same time, since the fixed connection piece cannot adapt to the slight error, the single glass needs to be accurately clamped to the fixed connection piece when the fixed connection piece is installed with four glasses, which requires high installation operation precision, and this will obviously reduce the installation efficiency. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application provides a glass curtain wall glass fixing device to solve the problem that the fixed connection piece cannot adapt to the position error of the mounting hole and thus cannot be installed on the glass when the position of the glass mounting hole exists.

[0005] To achieve the above purpose, the basic scheme of the present application is as follows: a glass curtain wall glass fixing device, comprising a supporting seat, further comprising:

[0006] A plurality of length-adjustable connection claws;

[0007] The connecting adjusting assembly between the connecting claw and the supporting seat comprises a steering seat, a plurality of adjusting rods and fixing bolts, the adjusting rods are arranged between the steering seat and the supporting seat, a rubber layer is wrapped on the side wall of the adjusting rod, a plurality of embedding grooves for the axial embedding of the adjusting rods and the rubber layers are arranged on the upper surface of the supporting seat, a connecting groove is communicated between two adjacent embedding grooves, the embedding groove and the connecting groove are communicated to form a ring-shaped adjusting groove, and the central angle between the two adjacent embedding grooves is less than or equal to 5°; the steering seat and the supporting seat are both provided with fixing holes in threaded connection with the fixing bolts, and the fixing holes are coaxially arranged with the ring-shaped adjusting groove; and the connecting claw is fixedly connected with the steering seat.

[0008] The technical principle of the present application is that when the glass is installed, the glass is first transferred to the frame structure, and then the fixing bolts at the fixing holes are loosened; then the steering seat is rotated, the steering seat is rotated relative to the supporting seat, and the steering seat drives the adjusting rods and the rubber layers to synchronously rotate; a single adjusting rod and a rubber layer pass through the connecting groove and enter the next embedding groove; since the central angle between the two adjacent embedding grooves is less than or equal to 5°, the central angle of the ring-shaped adjusting groove occupied by the embedding groove and the connecting groove is relatively small, and the steering seat can be rotated by an angle less than 5° around the counterbore when the adjusting rod and the rubber layer shift by one embedding groove, and the rotation of the steering seat can be stopped, and the rotation angle of the steering seat can be precisely adjusted through the adjusting rod, the rubber layer, the embedding groove and the connecting groove.

[0009] When the diameter of the installation hole on the glass and the axis of the connecting claw are located on the same radial radius of the ring-shaped adjusting groove, the rotation of the steering seat is stopped; then the length of the connecting claw is controlled so that the end of the connecting claw is opposite to the installation hole on the glass, and the matching between the entire glass curtain wall glass fixing device and the installation hole on the glass is completed, and then the connecting claw is connected with the installation hole.

[0010] Through the cooperation between the length-adjustable connecting claw and the steering seat and the supporting seat, the circumferential and radial positions of the end of the connecting claw are changed, the fine adjustment and cooperation with the position of the installation hole on the glass are facilitated, and the installation between the glass curtain wall glass fixing device and the glass is more reliable, efficient and convenient.

[0011] Further, a limiting ring is fixedly installed on the side of the steering seat close to the supporting seat, a ring-shaped flange is fixedly arranged on the inner wall of the end of the limiting ring away from the steering seat; the supporting seat is provided with a sliding groove for the axial movement of the limiting ring and the flange, and the longitudinal section profile of the sliding groove is in the shape of “L”; the sliding groove is coaxially arranged with the ring-shaped adjusting groove, and when the limiting ring and the flange abut against the bottom of the sliding groove, the end of the fixing bolt abuts against the bottom of the fixing hole.

[0012] When the steering seat is rotated relative to the support seat, the steering seat is first pulled to move away from the support seat, and the steering seat drives the adjusting rod, the rubber layer, the limiting ring and the flange to move away from the support seat, at this time, the limiting ring and the flange are loose with the sliding groove, and the rubber layer is also slightly loose with the embedded groove; when the flange abuts against the inner wall of the sliding groove, the pulling of the steering seat is stopped, the flange can abut against the sliding groove to lock the movement of the steering seat, and the adjusting rod and the rubber layer are prevented from being separated from the annular adjusting groove, which reduces the contact area between the annular adjusting groove and the rubber layer, so that the annular adjusting groove and the rubber layer are slightly loose, and the angle of the steering seat and the connecting claw is conveniently adjusted.

[0013] Further, the thickness of the horizontal section of the longitudinal section profile of the sliding groove is greater than or equal to the depth of the annular adjusting groove.

[0014] When the angle of the connecting claw is adjusted to the position, the steering seat is pressed into the support seat, the adjusting rod and the rubber layer are pressed into the embedded groove and the connecting groove, and the limiting ring and the flange slide to the bottom of the sliding groove; when the limiting ring and the flange slide to the bottom of the sliding groove, the end of the adjusting rod and the rubber layer abut against the bottom of the embedded groove and the connecting groove, and the close fit between the steering seat and the support seat is realized.

[0015] Further, the radial width of the connecting groove is greater than the diameter of the adjusting rod and less than the outer diameter of the rubber layer.

[0016] Through the above arrangement, when the rubber layer rotates relative to the connecting groove, the rubber layer is deformed by the inner wall of the connecting groove and the steel cable structure, and slowly enters the next embedded groove; during rotation, the deformation of the rubber layer causes a slight vibration of the hand, which facilitates the perception of the rotation angle of the steering seat, and the rotation of the steering seat is stopped in time.

[0017] Further, the number of embedded grooves is consistent with the number of adjusting rods.

[0018] Through the above arrangement, the embedded groove and the adjusting rod are one-to-one corresponding, so that after the steering seat abuts against the support seat, the steering seat and the support seat are closely fitted; at the same time, when the steering seat is rotated, the adjusting rods can provide interaction force to each other, so that the corresponding adjusting rod can stably enter the next embedded groove.

[0019] Further, the central angle of the single embedded groove occupying the annular adjusting groove is less than or equal to 3°.

[0020] Through the above arrangement, the spacing between the adjacent two adjusting grooves is further reduced, and the rotation angle of the steering seat can be more accurately controlled.

[0021] Further, the connecting claw comprises a connecting head and a connecting frame, the connecting frame comprises a first connecting rod and a second connecting rod, one end of the first connecting rod is fixedly connected with the steering seat, a length adjusting part is connected between the other end of the first connecting rod and one end of the second connecting rod, and the other end of the second connecting rod is fixedly connected with the connecting head.

[0022] Through the above setting, when the length of the adapter claw is controlled, the length of the first connecting rod and the second connecting rod is controlled by the length adjusting part, and the length of the first connecting rod and the second connecting rod is stable.

[0023] Further, the length adjusting part is a connecting sleeve, the connecting sleeve is coaxially sleeved on the first connecting rod and the second connecting rod, one end of the connecting sleeve is fixedly connected with the first connecting rod, and a first thread is arranged on the inner wall of the other end of the connecting sleeve. A second thread matched with the first thread is arranged on the outer wall of the end of the second connecting rod close to the first connecting rod.

[0024] Through the above setting, by screwing the second connecting rod on the connecting sleeve, the overlapping length of the connecting sleeve and the end of the second connecting rod is controlled, and then the length of the entire adapter claw is controlled. The control mode is simple and reliable, and the connection between the first connecting rod and the second connecting rod is stable.

[0025] Further, the connecting sleeve is provided with a welding hole in communication with the connecting sleeve at the end close to the first connecting rod.

[0026] Through the above setting, after the length of the adapter claw is adjusted, a welding wire is inserted into the welding hole, the welding wire is melted into the hollow of the connecting sleeve, and the connecting sleeve is filled, and at the same time, the welding of the connecting sleeve, the first connecting rod and the second connecting rod is realized. The full welding mode can improve the connection strength between the connecting sleeve, the first connecting rod and the second connecting rod, and then achieve the effect of strongly supporting the glass.

[0027] Further, a connecting head fixedly connected with the end of the first connecting rod close to the steering seat is fixedly arranged on the side of the steering seat away from the support seat, a counterbore in communication with the fixing hole is arranged on the connecting head, and the fixing bolt abuts against the counterbore of the connecting head.

[0028] Through the above setting, the adapter claw is fixed to the steering seat through the connecting head, and the installation and positioning of the fixing bolt are more stable due to the arrangement of the counterbore. BRIEF DESCRIPTION OF DRAWINGS
