Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to a pre-embedded sliding groove connector and construction method for cantilevered scaffolding for flower baskets. Background Technology

[0002] With the advancement of technology, urban buildings are becoming increasingly taller, and scaffolding is an indispensable technical means in the construction process. Cantilevered scaffolding has become an important component of scaffolding.

[0003] Traditional cantilever scaffolding requires a fixed end length exceeding 1.25 times the cantilever length, and leaves openings in the exterior wall, increasing construction difficulty and the risk of future water seepage. A more common type of cantilever scaffolding in recent years, known as "flower basket scaffolding," uses pre-embedded bolts to connect with the cantilevered I-beams, reducing the amount of I-beams used and avoiding the risks of patching holes and water seepage in the exterior wall. This technique requires precise positioning of the pre-embedded bolts, and the tightness of the nuts during anchoring directly affects the safety of the scaffolding. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pre-embedded sliding groove connector and construction method for cantilever scaffolding for flower baskets, so as to solve the problems of difficulty in positioning pre-embedded bolts and difficulty in controlling the quality of bolt connections in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is: a pre-embedded sliding groove connector for a cantilevered scaffold, comprising an embedded part and an I-beam; the front of the embedded part has two opposing sliding grooves along the longitudinal direction, and the back of the embedded part has anchoring bars; one end of the I-beam is fixed with a connecting plate, the connecting plate has a through hole on one side of the I-beam, and a nut is fixed at the position corresponding to the through hole on the connecting plate, and a bolt is installed on the nut; when installing the I-beam, the connecting plate is first slid into the sliding groove of the embedded part, and then the bolt is tightened so that its tail abuts against the embedded part, thereby fixing one end of the I-beam to the exterior wall of the building structure, while the other end of the I-beam supports the scaffolding uprights.

[0006] Furthermore, the embedded part is a steel plate, and two symmetrically arranged L-shaped steel plates are welded longitudinally on the front side of the embedded part, with each L-shaped steel plate forming a groove with the embedded part.

[0007] Furthermore, the length of the groove is equal to the length of the connecting plate.

[0008] Furthermore, the length of the embedded part is not less than twice the length of the connecting plate.

[0009] Furthermore, there are two anchor bars, which are distributed on the back of the embedded part at intervals. Each end of the anchor bar is provided with a vertical hook, and one end is welded to the embedded part.

[0010] Furthermore, one end of the I-beam is welded to the center of the connecting plate, and the other end supports the scaffolding uprights during use.

[0011] Furthermore, in use, the embedded part is embedded in the building structure, and the outer wall of the groove is flush with the outer facade of the building structure.

[0012] Based on the same inventive concept, this invention also provides a construction method for the above-mentioned pre-embedded sliding groove connector for cantilevered scaffolding for flower baskets, specifically including the following steps: Step 1: Before installing the exterior wall formwork, first embed the pre-embedded parts horizontally into the building structure; Step 2: After the exterior wall formwork is removed, once the concrete strength reaches the design requirements, the connecting plate of the I-beam slides into the groove on the front of the embedded part, so that the I-beam fixed on the connecting plate is perpendicular to the exterior facade of the building structure. Step 3: Screw the bolt into the nut of the connecting plate so that the tail of the bolt abuts against the embedded part; Step 4: The external scaffold uprights are vertically installed on the I-beams.

[0013] Furthermore, in step one, the anchor bars on the back of the embedded parts are firmly welded to the main reinforcement bars of the building structure, and the outer wall of the chute is flush with the outer facade of the building structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The construction method for connecting the I-beam to the building is simple, highly operable, and easy to implement. Embedded parts are components pre-installed during the building structure construction process, and the I-beam is connected to these embedded parts via connecting plates and tightened with bolts, thus achieving the installation and fixation of the I-beam. When dismantling the I-beam, simply loosen the bolts to allow it to slide out, which improves project quality and speeds up the project progress. 2. Compared with traditional cantilever scaffolding, the I-beams of this invention cantilever from the exterior wall of the building, which greatly reduces the amount of I-beams used and the use of anchor end pre-embedded rings, saving engineering costs and achieving the goal of cost reduction and efficiency improvement. It also avoids the risk of leakage caused by poor sealing of wall openings. 3. Compared with the existing basket-type cantilever scaffolding, the present invention adopts a pre-embedded part and an I-beam sliding connection, which avoids problems such as difficulty in positioning pre-embedded bolts and difficulty in controlling installation quality, and greatly improves the construction speed.

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.

[0018] Reference Figures 1 to 5 This embodiment provides a pre-embedded sliding groove connector for a cantilevered scaffold, including an embedded part 1 and an I-beam 2; the front of the embedded part 1 has two opposing sliding grooves 11 along the longitudinal direction, and the back of the embedded part 1 has anchoring bars 12; one end of the I-beam 2 is fixed with a connecting plate 21, and the connecting plate 21 has a through hole (not shown in the figure) on one side of the I-beam 2, and a nut 22 is fixed at the position corresponding to the through hole on the connecting plate 21, and a bolt 23 is installed on the nut 22; when installing the I-beam 2, the connecting plate 21 is first slid into the sliding groove 11 of the embedded part, and then the bolt 23 is tightened so that its tail abuts against the embedded part 1, thereby fixing one end of the I-beam 2 to the outer wall 4 of the building structure, while the other end of the I-beam 2 can support the scaffolding uprights 3.

[0019] In this embodiment, the embedded part 1 is a steel plate. Two symmetrically arranged L-shaped steel plates are welded longitudinally on the front side of the embedded part 1. A groove 11 is formed between each L-shaped steel plate and the embedded part 1. The length of the groove 11 is equal to the length of the connecting plate 21.

[0020] In this embodiment, the length of the embedded part 1 is not less than twice the length of the connecting plate 21.

[0021] In this embodiment, there are two anchor bars 12, which are distributed on the back of the embedded part 1 at intervals. Each end of the anchor bar 12 is provided with a vertical hook, and one end is welded to the embedded part 1.

[0022] In this embodiment, one end of the I-beam 2 is welded to the center of the connecting plate 21, and the other end supports the scaffolding uprights 3 during use.

[0023] In use, the embedded part 1 is embedded in the building structure, and the outer wall of the sliding groove 11 is flush with the outer facade of the building structure's outer wall 4.

[0024] This embodiment also provides a construction method for the pre-embedded sliding groove connector for the above-mentioned flower basket cantilever scaffolding, which specifically includes the following steps: Step 1: Before installing the exterior wall formwork, first embed the embedded part 1 horizontally into the building structure, and weld the anchor bar 12 on the back of the embedded part 1 firmly to the main bar of the building structure. The outer wall of the sliding groove 11 is flush with the exterior facade of the exterior wall 4 of the building structure. Step 2: After the exterior wall formwork is removed, once the concrete strength reaches the design requirements, the connecting plate 21 of the I-beam 2 slides into the groove 11 on the front of the embedded part 1, so that the I-beam 2 fixed on the connecting plate 21 is perpendicular to the exterior facade of the building structure exterior wall 4. Step 3: Screw the bolt 23 into the nut 22 of the connecting plate 21 so that the tail of the bolt 23 abuts against the embedded part 1; Step 4: The external scaffold uprights 3 are vertically installed on the I-beam 2.

[0025] Because the connection method of the present invention uses a pre-embedded groove to connect with the I-beam, installation and disassembly are convenient and quick, and leakage caused by inadequate sealing of wall openings is avoided.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
