Curtain wall back bolt type hanging piece

Abstract

This utility model relates to a back-bolt type curtain wall hanger. A Y-shaped guide strip is placed horizontally upside down. The upper branch of the Y-shaped guide strip slides in a groove on the upper part of a C-shaped guide strip. A slider on the lower part of the C-shaped guide strip slides in a groove formed by the upward arching of the lower branch of the Y-shaped guide strip. A limiting block extends upward from one end of the bottom of the groove. A limiting hole is provided on the slider corresponding to the limiting block, so that when the limiting block engages with the limiting hole, the two threaded holes on the upper part of the C-shaped guide strip and the upper branch of the Y-shaped guide strip are aligned. By setting a limiting hole on the slider and a limiting block in the groove, the relative positioning of the Y-shaped guide strip and the C-shaped guide strip is achieved. The alignment of the two threaded holes is achieved simply by engaging the limiting hole and the limiting block. This avoids the need for construction workers to repeatedly adjust the position of the Y-shaped guide strip relative to a fixed C-shaped guide strip to achieve the alignment of the two threaded holes, which is required in existing technologies. The relative positioning of the C-shaped guide strip and the Y-shaped guide strip in the back-bolt type hanger can be completed quickly, improving construction efficiency.

Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to a curtain wall back-bolt type hanger. Background Technology

[0002] With the rapid development of modern building curtain wall technology, the back-bolted dry-hanging system has been widely used in curtain wall projects using stone and ceramic panels due to its advantages such as convenient installation and structural stability. In existing technologies, back-bolted hangers typically employ a structure where C-shaped and Y-shaped guide strips are interlocked, and the curtain wall panels are fixedly connected by bolts (e.g., ...). Figure 8 ).

[0003] However, in actual construction, it was found that due to installation and positioning deviations between the C-shaped and Y-shaped guide strips, misalignment of the upper threaded holes frequently occurred when they were plugged in. This misalignment often required construction workers to repeatedly adjust the position of the Y-shaped guide strip relative to the fixed C-shaped guide strip, and sometimes even required on-site hole enlargement. This not only significantly reduced construction efficiency but also easily led to uneven preload on the connectors, affecting the safety performance of the curtain wall system. Especially in high-altitude working environments, manual alignment operations increased both construction safety hazards and project costs. Utility Model Content

[0004] The purpose of this utility model is to provide a curtain wall back-bolt type hanger to solve the above-mentioned problems existing in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A curtain wall back-bolt type hanger includes a C-shaped guide strip and a Y-shaped guide strip. The Y-shaped guide strip is placed horizontally upside down. The upper branch of the Y-shaped guide strip is slidably disposed in the groove of the upper part of the C-shaped guide strip. The lower slide strip of the C-shaped guide strip is slidably disposed in the groove formed by the upward arching of the lower branch of the Y-shaped guide strip. A limit block is provided at the bottom end of the groove opening. The slide strip has a limit hole corresponding to the limit block, so that when the limit block and the limit hole are engaged, the two threaded holes on the upper part of the C-shaped guide strip and the upper branch of the Y-shaped guide strip are aligned.

[0007] The beneficial effects of this utility model are: by setting a limiting hole on the slide bar and a limiting block in the groove, the relative positioning of the Y-shaped guide bar and the C-shaped guide bar can be achieved. The two threaded holes can be aligned by engaging the limiting hole and the limiting block. This avoids the need for construction workers to repeatedly adjust the position of the Y-shaped guide bar relative to the fixed C-shaped guide bar in the prior art to achieve the alignment of the two threaded holes. It can help construction workers quickly complete the relative positioning of the C-shaped guide bar and the Y-shaped guide bar in the back bolt type hanger, thus improving construction efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the spherical protrusion on the inner side of the limiting block is engaged with the spherical concave hole on the limiting hole.

[0010] The further beneficial effect of adopting the above is that the spherical protrusion and spherical concave hole clamping can limit the displacement of the slide bar in both the lateral and longitudinal directions within the groove, thereby improving the alignment accuracy of the threaded hole.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Example 1

[0023] like Figures 1 to 6As shown, a curtain wall back-bolt type hanger includes a C-shaped guide strip 1 and a Y-shaped guide strip 2. The Y-shaped guide strip 2 is placed horizontally upside down. The upper branch of the Y-shaped guide strip 2 is slidably disposed in the groove on the upper part of the C-shaped guide strip 1. The lower slide strip 11 of the C-shaped guide strip 1 is slidably disposed in the groove 21 formed by the upward arching of the lower branch of the Y-shaped guide strip 2. A limiting block 211 is provided at the bottom end of the groove 21. The slide strip 11 is provided with a limiting hole 111 corresponding to the limiting block 211, so that when the limiting block 211 is engaged with the limiting hole 111, the two threaded holes 12, 22 on the upper part of the C-shaped guide strip 1 and the upper branch of the Y-shaped guide strip 2 are aligned.

[0024] By setting a limiting hole 111 on the slide bar 11 and a limiting block 211 in the groove 21, the relative positioning of the Y-shaped guide bar 2 and the C-shaped guide bar 1 can be achieved. The two threaded holes can be aligned by engaging the limiting hole 111 and the limiting block 211. This avoids the need for construction workers to repeatedly adjust the position of the Y-shaped guide bar 2 relative to the fixed C-shaped guide bar 1 in the prior art to achieve the alignment of the two threaded holes. It can help construction workers quickly complete the relative positioning of the C-shaped guide bar 1 and the Y-shaped guide bar 2 in the back bolt type hanger, thus improving construction efficiency.

[0025] Example 2

[0026] like Figures 1 to 6 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0027] The spherical protrusion 2111 on the inner side of the limiting block 211 engages with the spherical concave hole 112 on the limiting hole 111. When the spherical protrusion 2111 and the spherical concave hole 112 engage, the displacement of the slide bar 11 in both the lateral and longitudinal directions within the groove 21 can be restricted, further improving the relative positioning accuracy of the Y-shaped guide bar 2 and the C-shaped guide bar 1, thereby improving the alignment accuracy of the threaded hole.

[0028] The upper surface of the connecting piece 23 of the Y-shaped guide strip 2 has a wavy toothed surface. It can be engaged with the pad with a wavy toothed surface at the bottom for auxiliary positioning. The contact surfaces between the C-shaped guide strip 1 and the Y-shaped guide strip 2 are polished. This reduces the friction between the contact surfaces, saving the labor of construction workers and construction time.

[0029] Example 3

[0030] like Figures 1 to 6 As shown, this embodiment is a further improvement on any one of embodiments 1 to 2, as detailed below:

[0031] Both C-shaped guide strip 1 and Y-shaped guide strip 2 are made of aluminum alloy. Aluminum alloy is easy to process, has low density and high strength, making it suitable for large-area use in dry-hanging curtain walls. In specific implementation, C-shaped guide strip 1 and Y-shaped guide strip 2 are made of 6063-T5 aluminum alloy.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
