Description

Technical Field

[0001] The invention belongs to the technical field of building structure curtain walls, and in particular relates to a device for realizing a three-way adjustment function of a curtain wall through a steel structure support. Background Art

[0002] With the rapid development of the construction industry, the continuous improvement of the level of construction technology, and the continuous improvement of people's aesthetic concepts, a large number of complex, high-tech, and beautiful building curtain walls have emerged. In particular, the glass curtain wall is a beautiful and novel method of building wall decoration, which is a significant feature of the modernist high-rise building era. The glass curtain wall has a good visual effect, and the light transmittance of the glass is very good. The intensity of indoor artificial lighting during the day can be greatly reduced. At present, glass with energy-saving properties such as thermal insulation and heat insulation, such as low-emissivity glass, has been widely used, which can save a lot of energy. The glass curtain wall can be divided into an exposed frame glass curtain wall and a hidden frame glass curtain wall. The main structure of the glass curtain wall is a building enclosure structure or decorative structure that has a certain displacement capacity relative to the main structure and does not share the effects of the main structure. The wall has two types of single-layer and double-layer glass. The special shape is used in the structure to highlight the novelty of the design and fully reflect the aesthetic effect of the design. The earliest curtain wall surface was made of steel materials, but nowadays, aluminum alloy keels and glass are mostly used. Especially when using hidden frame glass curtain walls, the glass is bonded to the aluminum frame with silicone structural sealant. The aluminum frame is completely hidden behind the glass to form a large area of ​​full glass mirror. The glass and the aluminum frame are completely bonded by structural adhesive. The invisible glass curtain wall structure needs to bear the dead weight of the glass, the wind load borne by the glass, and more external forces, as well as the influence of temperature changes. If the glass curtain wall is fixed only by sealant, there is an unstable fixation, which is prone to safety hazards and is not conducive to the stability of the building itself. On the other hand, most of the existing invisible glass curtain walls are often unable to be modified after installation, and the building curtain wall can only be dismantled and rebuilt, which will cause great waste. Summary of the invention

DETAILED DESCRIPTION

[0034] Embodiment 1: During the pouring process of the exterior wall 8 of a high-rise building, the embedded parts set in advance at intervals should have equal spacing, the same height, and should all be on the same horizontal plane, and the outer ends should all be on the same vertical plane. However, in fact, there is often a problem of position uncertainty deviation of each embedded part when pouring the exterior wall, resulting in the need for necessary adjustments during the curtain wall installation process. In view of the problem that the existing bracket used for curtain wall installation does not have the horizontal angle and vertical angle adjustment function, this embodiment uses a curtain wall multi-directional and multi-angle adjustment bracket that can adjust various angles and positions simultaneously.

[0035] The embedded part 11 used in this embodiment is as follows Fig. 9 and Fig.10 As shown, it is a strip-shaped structure, one side of which is open to form a transverse strip-shaped groove, and the strip-shaped groove includes an inner wide groove 11 and an outer narrow groove 12 , and the width of the inner wide groove 11 is greater than the width of the outer narrow groove 12 . Figure 5 It can be seen from the figure that the inner wide groove 11 has a rectangular cross section, and can also have a triangular or hexagonal cross section or other cross sections, as long as the width of the inner wide groove 11 is greater than the width of the outer narrow groove 12. Figure 1 and Fig.10 It can also be seen that the main body of the root bolt 2 is a screw rod, an inner clamping head is arranged at its inner end, and the threaded section at its outer end is used to connect and fix the nut 22, and the strip-shaped inner clamping head 21 is a rectangular body.

[0036] like Figure 1 and Fig. 9 As shown, a bolt 2 is installed at each end of the strip groove, and the following conditions are met: the width of the rectangular body is not greater than the width of the outer narrow groove 12, and the length of the rectangular body is greater than the width of the outer narrow groove 12 but less than the width of the inner wide groove 11. Figure 1 When the root bolt 2 and the strip-shaped inner clamp 21 shown in the figure are inserted into the strip groove, the strip-shaped inner clamp 21 is kept horizontal so that it can be inserted into the outer narrow groove 12. After the strip-shaped inner clamp 21 enters the inner wide groove 11 and rotates 90 degrees, the strip-shaped inner clamp 21 becomes vertical as shown in the figure. Figure 4 As shown, it cannot fall off from the bar groove.

[0037] Based on the above structure and assembly relationship, the root bolts 2 on both sides can slide laterally in the strip grooves respectively, that is, the preliminary lateral adjustment function is realized.

[0038] like Figure 1 As shown, a middle support point 6 is mounted in the middle of the strip-shaped groove, and a middle support spherical body 61 protrudes outward from the middle support point 6.

[0039] like Figure 1 As shown, an outer bracket 3 is installed at the position of the root bolt 2 and fixed. Figure 5-Figure 7The outer bracket 3 shown includes a transverse plate 31 and vertical plates 32 vertically connected on both sides, and the vertical plates 32 on both sides are in a symmetrical relationship.

[0040] like Figure 3 and Figure 5 As shown, arc adjustment holes 34 are respectively provided at both ends of the horizontal plate 31 as vertical rotation adjustment holes, and the center of the arc coincides with the center of the middle spherical body 61; the root bolts 2 located on both sides of the strip groove are led out from the corresponding vertical rotation adjustment holes and fixed by the fixing nut 22.

[0041] like Figure 1 As shown, the middle spherical body 61 of the middle support 6 is supported on the middle part of the inner wall of the outer bracket 3. Therefore, when the fixing screw nuts 22 on the root bolts 2 on both sides are tightened and adjusted respectively, the outer bracket 3 can be controlled to rotate horizontally along the middle support 6. Figure 2 As shown, the outer bracket 3 is adjusted horizontally. Similarly, when the screw nuts 22 at both ends are locked, the outer bracket 3 can be adjusted to rotate vertically. Figure 4 As shown, the vertical rotation adjustment function of the outer bracket 3 is realized.

[0042] Based on the above structure, the lateral movement function, horizontal rotation adjustment function and vertical rotation adjustment function of the outer bracket 3 can be realized. The above adjustment function is due to the fact that the embedded part 11 may have various non-standard position adjustments. The outer bracket 3 is detected by the leveling instrument, and the outer bracket 3 is moved into position to keep it horizontal, and the outer bracket 3 is located at the same horizontal position and the same vertical position as the adjacent outer bracket 3. The outer bracket 3 is locked by fixing the nut 22. After the outer bracket 3 is locked, the longitudinal movement adjustment and lifting adjustment are performed on the basis of the outer bracket 3.

[0043] like Figure 5 As shown, longitudinal flat holes are respectively provided on the vertical plates 32 as longitudinal adjustment holes 35. The longitudinal adjustment holes 35 on the vertical plates 32 on both sides are crossed by the cross-connecting screw rods 4. Figure 1 and Figure 3 The end of the cross-connecting screw 4 outside the vertical plate 32 is fixedly connected to the end fixing nut 41, and the middle section of the cross-connecting screw 4 between the vertical plates 32 on both sides is installed with a limited adjustment nut 42.

[0044] Therefore, the cross-connecting screw rod 4 can be adjusted in translation along the longitudinal direction, and the cross-connecting screw rod 4 can be fixed by the end fixing nuts 41 at both ends.

[0045] A hanging member 5 is hung on the cross-connecting screw rod 4, and the hanging member 5 is connected to the curtain wall body. The hanging member 5 is positioned and fixed by a limit adjustment nut 42. Figure 8The hanging part 5 shown includes a vertical curtain wall connecting plate 51 and a hanging plate 52, and a deep groove 53 is formed between the two plates. The deep groove 53 is seated on the cross-connecting screw 4, and a screw hole is provided at the top of the deep groove 53 and an end height fine-tuning wire 54 is installed. The lower end of the height fine-tuning wire is supported on the cross-connecting screw 4.

[0046] In the above structure, after the outer bracket 3 is adjusted horizontally, horizontally, vertically and horizontally before the curtain wall body is installed, the height of both ends of the curtain wall body is adjusted respectively through the height fine-tuning wire after the curtain wall is installed, thereby realizing the function of adjusting the position and angle of the curtain wall body at any position. The bracket has a simple structure, low cost, easy batch manufacturing and convenient use.

[0047] Embodiment 2: Based on Embodiment 1, a middle support spherical groove 65 is provided in the middle of the inner wall of the outer bracket 3, and the middle support spherical body 61 is matched and fitted in the middle support spherical groove 65. The support spherical groove is used to constrain the position of the outer bracket 3 and the middle support point 6. Since the arc adjustment holes 34 on both sides of the outer bracket 3 have constrained the corresponding root bolt 2 positions, the middle support spherical body 61 and the root bolts 2 on both sides can be constrained together by providing the middle support spherical groove 65 structure in this embodiment, that is, the synchronous translation function of the three is realized. No matter where the outer bracket is translated horizontally, the three can be ensured to move synchronously, so that the middle support point 6 is always located in the middle of the root bolts 2 on both sides, that is, located in the middle of the outer bracket 3, to ensure symmetrical adjustment of the two ends when the angle is adjusted.

[0048] Embodiment 3: Based on Embodiment 1, the middle support 6 includes a middle support spherical body 61, a strip inner clamp 62 and a neck 63. The strip inner clamp 62 is a rectangular body. The width of the rectangular body is not greater than the width of the outer narrow groove 12. The length of the rectangular body is greater than the width of the outer narrow groove 12 but less than the width of the inner wide groove 11. The strip inner clamp 62 is installed in the inner wide groove 11, and the neck 63 is installed in the outer narrow groove 12, and then rotated 90 degrees. Further, a joint plate 7 is installed on the outer side of the root bolt 2 and the middle support 6 at the same time, such as Fig.12 As shown, the joint plate is provided with positioning holes 71 for installing the corresponding root bolts 2 and the middle support 6, and the root bolts 2 on both sides and the middle support 6 in the middle are connected as a whole. The joint plate is used to constrain the position of the outer bracket 3 and the middle support 6. In this embodiment, the assembly is provided as shown in FIG. Fig.12 After the connected plate 7 is shown, the positions of the middle support spherical body 61 and the root bolts 2 on both sides can be constrained together, that is, the synchronous translation function of the three is realized. No matter where the outer parts are translated horizontally, the three can be ensured to move synchronously, so that the middle support point 6 is always located in the middle of the root bolts 2 on both sides, that is, located in the middle of the outer bracket 3, ensuring symmetrical adjustment of the two ends when adjusting the angle.

[0049] Embodiment 4: Based on embodiment 3, Fig.13As shown, the middle support 6 includes a middle support spherical body 61, a strip inner clamp 62 and a neck 63. The strip inner clamp 62 is a rectangular body, the width of which is not greater than the width of the outer narrow groove 12, and the length of which is greater than the width of the outer narrow groove 12 but less than the width of the inner wide groove 11. The strip inner clamp 62 is installed in the inner wide groove 11, and the neck 63 is installed in the outer narrow groove 12, and then rotated 90 degrees. Fig.14 As shown, the neck 63 is a screw segment, which can be threadedly connected with the spherical middle spherical body 61. Further, the neck 63 is provided with a thread and a locking nut 64 is installed, and the locking nut 64 is located outside the outer narrow groove 12 and supported at the notch of the outer narrow groove 12 of the embedded part 11.

[0050] Example 5: On the basis of Example 1 or 2, in order to prevent the root bolt 2 from rotating naturally during the assembly process, a root lock nut is further threadedly installed on the root bolt 2. The root lock nut is located outside the outer narrow groove 12 and supported on the notch of the outer narrow groove 12 of the embedded part 11, so that the root bolt 2 can be fixed and constrained in the strip groove through the root nut without rotating and sliding.
