Description

Technical Field

[0001] The utility model relates to the technical field, in particular to the technical field of newly adding curtain wall keels at the corners of old masonry houses and post-embedded parts. Background Art

[0002] When it is necessary to add aluminum curtain wall to an old masonry house, Figure 7 For this type of structure, the original house does not have structural columns at the corners, and the walls are aging. If it is necessary to add a structure at the corner, it is necessary to install post-embedded parts on the original corner walls. The post-embedded parts are fixed to the original walls by chemical anchors or expansion anchors. For specific practices, please refer to the "Technical Code for Post-Anchoring of Masonry Structures" T / CECS497-2017. However, according to Article 7.0.3 of the code, if an anchor with a diameter of 10mm is used, the minimum distance between the anchor and the edge of the substrate shall not be less than 4hef, ​​that is, not less than 240mm. When the cantilevered aluminum plate is set at the corner, embedded parts and anchors are required at the corner. Traditional post-embedded parts are as shown in the attached manual. Figure 8 As shown, this type of post-embedded part is directly fixed to the bottom surface of the corner by anchor bolts. At this time, the anchor bolts are often only tens of millimeters away from the edge of the substrate, which cannot meet the requirements of the regulations at all. It is also very easy to cause wall splitting and damage, anchor bolt failure, and quality and safety accidents. In addition, the force direction is single, the stability is poor, and it is easy to loosen and fall off. A new type of post-embedded part is needed, and the existing post-embedded parts need to be punched before installation. In order to improve the accuracy during the punching process, the post-embedded parts need to be attached to the wall surface to facilitate the positioning of the holes. This requires another person to assist in punching and press the post-embedded parts on the wall surface. The process is cumbersome and requires the assistance of others. Summary of the invention
