Description

Technical Field

[0001] The utility model belongs to the technical field of building curtain walls, and particularly relates to a post-embedded part connection structure for post-welding-free. Background Art

[0002] The domestic building curtain wall industry started in the 1980s. After decades of vigorous development and iterative innovation, the overall market volume and technical level have ranked first in the world. Due to the limitations of the era, the functional and ornamental properties of a large number of building envelope structures built in the late 20th century can no longer meet the needs of the new era, and urgent demolition and reconstruction are required. As is well known, the service life of the main structure of general buildings is greater than or equal to 50 years, while the service life of building curtain walls as envelope structures is generally about 25 years. This means that most buildings will face the situation of demolishing and replacing the exterior walls decades after they are put into use. Based on this, we believe that whether based on the current market situation or future expectations, the demolition and renovation of curtain walls in existing projects are a market with broad prospects. The renovation of existing projects needs to retain the original building main structure, resulting in an extremely large usage scenario for post-embedded parts.

[0003] In the installation process of traditional curtain walls, the adapter and the embedded part are often connected by welding technology. However, in the construction process, the splashing of sparks during welding is likely to cause safety accidents such as fires; welding is a special process, with high technical requirements for professional operators, and safety accidents caused by welding quality also occur from time to time. In recent years, in response to national construction goals such as "carbon neutrality", more attention has been paid to environmental protection, and situations such as welding bans and construction stoppages on construction sites due to factors such as heavy pollution weather have become more frequent, seriously restricting the progress of engineering projects.

[0027] Reference Figure 1 As shown, an embodiment of the present utility model provides a connection structure for a post - welded embedded part without welding, including a first connecting piece 1 and a second connecting piece 2.

[0028] Reference Figure 2 and 3 As shown, the first connecting piece 1 includes a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 is a U - shaped structure, and the second connecting portion 12 is a flat - plate structure. The number of the second connecting portions 12 is two, and they are respectively arranged at the two free ends of the first connecting portion 11, and both of the two second connecting portions 12 extend outward.

[0029] A strip - shaped hole 13 is respectively arranged at positions near both ends of the first connecting portion 11 in the width direction, and an avoidance notch 14 is arranged at the middle position of the strip - shaped hole 13.

[0030] The outer surface of the first connecting portion 11 is provided with first anti - slip lines, and the outer side surface of the second connecting portion 12 is provided with second anti - slip lines. The first anti - slip lines and the second anti - slip lines can increase the friction force between the components in contact with them and reduce the probability of loosening or sliding. For example, a gasket will be installed on the outer side of the second anti - slip lines, and the second anti - slip lines can increase the friction force between it and the gasket and reduce the probability of the locking nut loosening.

[0031] At least two first bolt holes 15 are arranged on each second connecting portion 12, and the first bolt holes 15 are located within the range of the second anti - slip lines.

[0032] Reference Figure 4 and 5 As shown, the second connecting piece 2 includes a third connecting portion 21 and a fourth connecting portion 22. Both the third connecting portion 21 and the fourth connecting portion 22 are plate - shaped structures. The number of the fourth connecting portions 22 is two, and the two fourth connecting portions 22 are arranged in parallel at intervals on one side surface of the third connecting portion 21 to form a π - shaped structure. The width dimension of the fourth connecting portion 22 is smaller than the width dimension of the third connecting portion 21. The third connecting portion 21 is used to fit with the first connecting portion 11, and the fourth connecting portion 22 is located on the side of the third connecting portion 21 away from the first connecting portion 11. The third connecting portion 21 is detachably connected to the first connecting portion 11, which is convenient for disassembly and assembly.

[0033] A through hole 23 is provided at a position on the third connecting portion 21 corresponding to the strip-shaped hole 13, and two through holes 23 correspond to each strip-shaped hole 13.

[0034] A third anti-slip pattern is provided on a surface of the third connecting portion 21 close to the first connecting portion 11, and a fourth anti-slip pattern is provided on an outer surface of the fourth connecting portion 22. The third anti-slip pattern fits with the first anti-slip pattern, greatly increasing the friction between the third connecting portion 21 and the first connecting portion 11. The fourth anti-slip pattern can increase the friction with the gasket and reduce the probability of bolt loosening.

[0035] At least two second bolt holes 24 are provided on the fourth connecting portion 22, and the second bolt holes 24 on the two fourth connecting portions 22 correspond to each other one by one.

[0036] During use, an expansion bolt is passed through the first bolt hole 15 to fix the first connecting member 1 to the wall. Then, bolts are passed through the clearance notch 14 into the strip-shaped hole 13, and two bolts are inserted into each strip-shaped hole 13. The distance between the two bolts is adjusted, and then the through hole 23 of the third connecting portion 21 is aligned with the bolts and passed through, so as to fix the second connecting member 2 to the first connecting member 1. Finally, the column is fixed between the two fourth connecting portions 22.

[0037] The present utility model is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present utility model, they are all within the protection scope of the present utility model.
