Technical Field

[0001] The utility model relates to the technical field of curtain wall embedded parts, in particular to a curtain wall embedded part used for grouting and leveling old masonry. Background Art

[0002] It is quite common to add aluminum curtain walls to the facade renovation projects during the upgrading and renovation of old urban areas and residential areas. Aluminum curtain walls are added to the exterior walls of old masonry houses. The traditional method of aluminum curtain walls is to make curtain wall keels first and then lay aluminum plates. The specific installation process is: drill holes to implant chemical anchor bolts → install buried plates → weld curtain wall keels → install curtain walls.

[0003] The traditional installation process mentioned above has many steps and a long construction period; the steel structure keel consumption is large and the cost is high; the curtain wall structure is heavy and the original structure has a high safety risk; the embedded plate is fixed with chemical anchor bolts, and the qualified guarantee rate of chemical anchor bolts implanted in old masonry walls is not high, leaving safety hazards to the structural safety of the project; and the old masonry exterior wall is loaded heavily, increasing the structural safety risk of the original masonry house. Summary of the invention

[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide a grouting and leveling curtain wall embedded part for old masonry. The grouting and leveling curtain wall embedded part can be used to install the aluminum plate curtain wall on the old masonry, and the structural keel-free installation can be achieved. The use of this embedded part greatly simplifies the curtain wall installation process, which not only saves construction time, but also saves engineering costs. Moreover, since this process does not require structural keels, the weight of the aluminum plate curtain wall is greatly reduced, and the impact on the structural safety of the original old wall is smaller.

[0005] The technical solution adopted by the utility model to achieve its technical purpose is: a grouting and leveling curtain wall embedded part for old masonry, including a pre-embedded part, the pre-embedded part includes a plurality of anchor bars, one end of the plurality of anchor bars is cross-fixed and connected, and the other end is fixed with an anchor plate, the outer walls of the plurality of anchor bars are provided with a spiral hoop for welding and fixing, the plurality of anchor bars are welded together with the spiral hoop through the spiral hoop, and the spiral hoop can act as a thread, so as to facilitate the spiral connection of the embedded part.

[0006] A grouting hole is provided inside the anchor plate, and a closed sleeve is fixed on one side of the anchor plate. An overflow hole is provided on one side of the closed sleeve. A grouting catheter is inserted into the grouting hole, and micro-expansion fast-strength C fine stone concrete is injected at high pressure from the bottom of the hole until slurry flows out of the overflow hole.

[0007] The embedded part is screwed into the installation hole opened inside the wall by rotation.

[0008] Preferably, four anchor bars are provided, one end of each anchor bar is bent and cross-welded, and the cross-welding can increase the stability of one end of the anchor bar and make it less likely to deform.

[0009] Preferably, the hole of the mounting hole is arranged horizontally, and the hole diameter is mm and the depth is mm.

[0010] Preferably, a plurality of embedded parts are provided, and after they are rotated and screwed into the mounting holes, the verticality of the plurality of embedded parts remains consistent, so that the surfaces of the aluminum plate are basically in the same plane after installation.

[0011] Preferably, the closed sleeve is sleeved outside the other end of the anchor bar and the spiral hoop, and after the embedded part is screwed into the installation hole by rotation, one end of the closed sleeve is tightly pressed against the outer wall of the wall.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the grouting and leveling curtain wall embedded parts used for old masonry, the grouting and leveling curtain wall embedded parts can be used to install the aluminum plate curtain wall on the old masonry, and the installation without structural keels can be achieved; and the use of this embedded part greatly simplifies the curtain wall installation process, which not only saves construction time but also saves engineering costs; furthermore, since this process does not require structural keels, the weight of the aluminum plate curtain wall is greatly reduced (about half), and the grouting and leveling curtain wall embedded parts can also be integrated with the house wall, which has less impact on the structural safety of the original old wall, achieving multiple goals at one stroke.

The channel of the mounting hole 101 is horizontally set, and the opening diameter is 85mm and the depth is 170mm. There are multiple embedded parts 2. After they are rotated and screwed into the mounting hole 101, the vertical verticality of the multiple embedded parts 2 remains consistent.
