Description

Technical Field

[0001] This invention relates to the field of exterior wall decoration technology, and in particular to the fixing between the exterior wall decorative layer and the masonry wall when the exterior surface of a building is made of exposed brick wall as the decorative layer. Background Technology

[0002] Exposed brick walls, a common type of exterior wall in construction, are frequently used in the reconstruction of historical districts in China due to their diverse surface styles and finishes. However, if used directly as an enclosure structure, exposed brick walls no longer meet the functional requirements of modern buildings in terms of insulation and heat resistance. Therefore, during construction, exposed brick walls are often used as the exterior facade cladding, built on the outside of the secondary structural walls. Furthermore, to ensure the stability of the exposed brick walls, a tie rod must be installed between them and the internal secondary structural walls.

[0003] Currently, the common method used is to connect exposed brick walls with internal secondary structural walls by setting tie bars. However, this method has the following two drawbacks:

[0004] First, the reinforcing bars are connected by friction with the mortar in the joints of the secondary structural walls and the exposed concrete walls. The tie bars are usually plain round steel bars, and it is difficult to guarantee the bond strength between them and the mortar.

[0005] Secondly, the tie bars penetrating the waterproof layer on the surface of the secondary structure will create weak points in the waterproofing of the secondary structure wall, leaving hidden dangers for the waterproofing performance of the building's exterior wall. Summary of the Invention

[0006] This invention addresses the problems and shortcomings of existing technologies by providing a connection device between an exterior wall finish layer and a masonry wall.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] This invention provides a connection device between an exterior wall cladding layer and a masonry wall, characterized by three embedded components: a first embedded component, a connecting component, and a second embedded component. The first embedded component includes a connecting rod at the front end and a toothed anchor plate at the rear end. The connecting component includes a connecting plate and a sliding nut. The second embedded component includes a plate-shaped anchor plate at the front end and an embedded plate at the rear end.

[0009] The toothed anchor plate is fixed inside the secondary structural wall. The top of the connecting rod is threaded and protrudes outside the secondary structural wall. It is connected to the sliding nut. The sliding nut is fixed in the groove in the middle of the connecting plate and can slide up and down. The embedded plate passes through the groove in the connecting plate from the inside of the connecting plate. After the plate anchor plate and the connecting plate are snapped together, they are fixed inside the fair-faced wall. The above structure connects the fair-faced wall and the secondary structural wall into one.

[0010] The toothed anchor plate is a rectangular thin plate with serrated openings on both sides and bottom, and a circular hole with intervals in the middle. The top is welded to the connecting rod. The connecting rod is fitted with a water-sealing plate to block the water seepage path from the sliding nut to the connecting rod. The second embedded component is a T-shaped structure with a long strip of thin plate and protrusions on the surface. The first embedded component, the connecting component, and the second embedded component are all made of stainless steel.

[0011] By using the tie device between the exterior wall finish layer and the masonry wall, an effective tie can be achieved between the exposed concrete wall and the secondary structure wall. By setting up a water-sealing board and waterproof gasket, the waterproof performance of the tie device can be improved, avoiding the situation where the waterproof layer of the wall is damaged due to the installation of the waterproof device, thus preventing the formation of leakage points.

[0012] This device achieves the following innovations:

[0013] 1. Increase anchoring force by setting serrated openings, perforations, and surface embossing in the anchors.

[0014] 2. Improve the waterproof performance of the tie-up device by setting a water-sealing plate and a waterproof gasket.

[0015] 3. By setting a groove on the connecting plate, the size of the anchor plate in the fair-faced concrete wall can be adjusted, avoiding the situation where the horizontal mortar joints of the fair-faced concrete wall and the secondary structural wall are not aligned, making it difficult to install the anchors, or bending and deforming the anchors on site to reduce the anchoring force for installation.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, this embodiment provides a connection device between an exterior wall cladding layer and a masonry wall, which includes a pre-embedded component 1, a connecting component 2, and a pre-embedded component 3. The pre-embedded component 1 includes a connecting rod 11 at the front end and a toothed anchor plate 12 at the rear end. The connecting component 2 includes a connecting plate 21 and a sliding nut 22. The pre-embedded component 3 includes a plate-shaped anchor plate 31 at the front end and an embedded plate 32 at the rear end.

[0023] The toothed anchor plate 12 is fixed inside the secondary structural wall 10. The top of the connecting rod 11 is threaded and protrudes outside the secondary structural wall 10. It is connected to the sliding nut 22. The sliding nut 22 is fixed in the groove 211 opened in the middle part of the connecting plate 21. The embedded plate 32 passes through the groove 211 opened in the connecting plate 21 from the inside of the connecting plate 21, and snaps the plate-shaped anchor plate 31 with the connecting plate 21. The plate-shaped anchor plate 31 is fixed inside the clear water wall 20.

[0024] The construction process involves the following steps:

[0025] 1. When constructing the internal secondary structural wall 10, place the pre-embedded component 1 at the mortar joint. When pre-embedding the pre-embedded component 1, make sure that the inside corner between the toothed anchor plate 12 and the connecting plate 21 is tightly clamped to the outside corner of the masonry wall.

[0026] 2. After the secondary structural wall 10 is completed, a plastering leveling layer, a waterproof layer, and a waterproof protective layer shall be constructed on the outer surface of the secondary structural wall 10 to prevent water from entering the wall.

[0027] 3. Install the waterproof gasket 4 onto the connecting rod 11 of the pre-embedded component 1.

[0028] 4. Pass the embedded plate 32 of the pre-embedded component 2 3 through the groove 211 on the connecting plate 21 of the connecting component 2.

[0029] 5. The connecting component 2 and the second embedded component 2 are screwed onto the connecting rod 11 of the first embedded component 1 through the screw hole on the sliding nut 22 on the connecting component 2. The sliding nut 22 and the thread on the connecting rod 11 are engaged with each other.

[0030] 6. Construct the exposed brick wall 20 for the exterior of the building. By sliding the embedded component 2 3 up and down in the groove 211, adjust the height of the embedded component 2 3 so that the embedded plate 32 of the embedded component 2 3 can be placed in the horizontal mortar joint of the exposed brick wall 20.

[0031] Thus, through the aforementioned connection device between the exterior wall finish layer and the masonry wall, the exposed concrete wall 20 and the secondary structural wall 10 are connected as one.

[0032] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
