Description

Technical Field

[0001] This utility model mainly relates to the field of prefabricated buildings, specifically a prefabricated building keel installation structure. Background Technology

[0002] Prefabricated construction transfers a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated construction first installs the longitudinal beams, then the upper and lower horizontal beams, and finally the intermediate joists. Currently, there are two main methods for installing the joists: external hanging and internal embedding. External hanging installation structures occupy more space, while internal embedding installation requires double fixing to both the joists and longitudinal beams, which is more difficult to operate and install due to limited space. Utility Model Content

The longitudinal beam has a through hole allowing the keel to pass through. Connectors A and B each include a mating groove adapted to the side of the keel and an outer flange edge. Connector A has a plug groove, and connector B has a plug joint that mates with the plug groove. When connectors A and B are mated, the mating grooves of connectors A and B align to form the outer contour of the keel. The flange edge has flange mounting holes for bolt connection with the longitudinal beam.

[0005] Preferably, the longitudinal beam is a C-shaped steel, and an extension arm is provided on the flange side. The end of the extension arm is provided with a folded edge that abuts against the side wall of the C-shaped steel longitudinal beam. The folded edge has a folded edge mounting hole for bolt connection with the side wall of the longitudinal beam.

[0013] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application. Example

[0014] As shown in the figure, the prefabricated building keel installation structure of this utility model includes a longitudinal beam 1, a keel 2, and connectors A and B. The longitudinal beam 1 is fastened to the foundation by bolts, and crossbeams are installed at the top and bottom of the longitudinal beam 1. The longitudinal beam 1 is a C-shaped steel beam with through holes 11 that allow the keel to pass through. The keel passes through the through holes 11 and is installed on the longitudinal beam 1 for attaching and installing insulation boards, wall panels, and other materials, and also serves as an installation channel for water and electricity pipes.

[0015] Connector A and connector B mate together, and through the mating assembly of connector A and connector B, they serve as the connecting parts for the installation of keel 2. During installation, connector A and connector B are installed in an vertical position.

[0016] In this embodiment, both connector A and connector B include a mating groove 31 that mates with the side of the keel 2 and an outer flange edge 32. When connector A and connector B are mated together, the mating grooves 31 of connector A and connector B mate to form the outer contour of the keel 2, and the diameter of the two mating grooves 31 is slightly larger than the diameter of the keel 2, so that the keel 2 can be more stably supported and fixed, thus completing the installation of the keel 2.

[0017] Connector A has a insertion slot 33, and connector B has a plug 34 that mates with the insertion slot 33. In this embodiment, the insertion slot 33 is a trapezoidal slot, and the plug 34 is a trapezoidal head. The trapezoidal slot and the trapezoidal head are fitted together. Through the insertion fit, connector A and connector B can be assembled as a whole, thereby allowing the keel 2 to be installed stably. The separate structure of connector A and connector B makes it easier to install on the keel 2 and provides stable load-bearing capacity for the keel 2.

[0018] The flange edge 32 has flange mounting holes for bolting to the longitudinal beam 1. Elongated holes are formed around the top of the through hole 11 in the longitudinal beam 1. The flange mounting holes of the connectors correspond to these elongated holes, allowing connectors A and B to be fixed to the longitudinal beam 1 by tightening the bolts. In this embodiment, threaded holes are formed on the side of connector A or connector B, and fastening bolts are installed in these holes. The tightening action of the fastening bolts secures the keel 2 installed inside, preventing it from sliding. Example

[0019] Compared with Embodiment 1, the structures of connector A and connector B are different in this embodiment. In this embodiment, an extension arm 35 is connected to the flange edge 32 of the connector. The extension arm 35 can be processed by welding or bending. The end of the extension arm 35 is provided with a flange 36 that abuts against the side wall of the C-shaped steel longitudinal beam 1. The flange 36 has flange mounting holes for bolt connection with the side wall of the longitudinal beam 1. The side of the longitudinal beam 1 has elongated holes, and the flange mounting holes correspond to the elongated holes. By tightening the bolts, the connection between connector A and connector B and the two sides of the longitudinal beam 1 can be realized.

[0020] In this implementation, the keel can be installed more stably through the double fixing of the flange edge 32 and the folded edge 36. Example

[0021] In addition to Embodiments 1 and 2, this embodiment further includes a tightening mechanism 4. Connector A and connector B have extension sleeves 37 at their bottoms that mate with through holes 11. During installation, the left and right sidewalls of the extension sleeves 37 contact the inner sidewalls of the through holes 11. One of the connectors has a protruding ring 38 on its extension sleeve 37, which faces downwards during installation. The tightening mechanism 4 includes a tightening ring 41 and a tightening stud 42, and is tensioned between the extension sleeve 37 and the bottom of the through hole 11. The tightening mechanism 4 supports the bottom of the installed keel 2 and levels it. When the tightening mechanism 4 is tightened, its top abuts against the protruding ring 38.

[0022] Specifically, the tightening ring 41 is threadedly connected to the tightening stud 42. The tightening stud 42 has a suspension part on its outer wall. The top of the tightening stud 42 mates with the convex ring 38. The bottom of the tightening ring 41 is provided with a slot 43 adapted to the thickness of the longitudinal beam 1. In use, the slot 43 is engaged with the bottom edge of the through hole 11, and then the tightening stud 42 is unscrewed, increasing the relative length between the stud 42 and the tightening ring 41. The top of the stud 42 tightens the keel 2, leveling and supporting the keel 2 during installation.
