Description

Technical Field

[0001] This utility model belongs to the field of ceiling engineering technology, specifically a hemispherical universal hanger for ceiling keel. Background Technology

[0002] As a key carrier of force transmission, the structural design of ceiling joist connectors directly affects the stability and aesthetic appearance of the ceiling system. Traditional solutions use stamped Z-shaped steel components, achieving a rigid vertical connection between the hangers and the joists via bolts. In orthogonal ceiling systems, this approach offers advantages such as simple structure and a clear force transmission path. However, this structure has the following inherent drawbacks:

[0003] 1. When the hanger rod and the keel are not perpendicular, it is common in irregular structures such as curved ceilings and sloping ceilings. The rigid bending structure of the Z-shaped part cannot compensate for the angle deviation, resulting in the twisting of the installation surface or connection failure.

[0004] 2. Angular deviations force components to undergo localized plastic deformation, and stress concentration points are formed at locations prone to bending under dynamic loads, thus reducing fatigue life.

[0005] 3. Each angle adjustment requires on-site cutting, bending, and re-drilling, increasing the complexity of high-altitude operations and making the construction of irregular ceilings too time-consuming. Utility Model Content

[0006] The main purpose of this utility model is to provide a hemispherical universal hanger for ceiling keel that allows for multi-angle adjustment of the hanger rod and the keel.

[0007] The hemispherical universal hanger for ceiling keel provided by this utility model includes a hanger rod, a ball head, a ball head seat, a ball head cover, and a connector. The ball head is a hemisphere with an internal threaded interface at the top, and the lower end of the hanger rod is threadedly connected to the ball head. The ball head seat has a hemispherical groove at the top that matches the outer contour of the ball head, and a load-bearing plate at the bottom. The ball head cover is fitted onto the outside of the ball head seat, and its top has a through hole for the hanger rod to pass through. The connector is located at the bottom of the ball head seat. The ball head is rotatably embedded in the groove of the ball head seat, forming a multi-directionally adjustable spherical sub-mechanism.

[0008] In one embodiment of the above-mentioned lifting device, the top of the ball head cap is provided with a locking assembly, including a nut screwed onto the lifting rod and a washer located under the nut, and force is applied to the ball head cap by tightening the nut.

[0009] In one embodiment of the above-mentioned lifting component, the bearing plate of the ball head seat is a rectangular plate with two sets of symmetrical riveting holes at its bottom; the connecting component is a U-shaped stamped component, including a web plate and two side flanges, and the flanges are provided with mounting holes corresponding to the riveting holes of the ball head seat.

[0010] In one embodiment of the above-mentioned lifting component, the ball head seat and the keel connector are fixedly connected by anti-loosening rivets.

[0011] In one embodiment of the above-mentioned lifting component, the ball head cap is a hemispherical stamped part, and the curvature of its inner cavity is consistent with the outer contour of the ball head seat.

[0012] In one embodiment of the above-mentioned lifting component, the lifting rod is a fully threaded rod.

[0013] In one embodiment of the above-mentioned lifting component, the ball head seat is made of cast steel, and the ball head cover is made of hot-dip galvanized steel sheet.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the cooperation of the ball head, ball head cap, and ball head seat, a rotatable universal ball joint is formed. This structure allows the hanger and keel to be adjusted at multiple angles when not perpendicular, without the need for additional tools or complex adjustments; it significantly improves the adaptability of the hanger and meets the installation requirements of irregular ceilings such as curved or angled surfaces; it ensures that the ceiling transition layer is flat, straight, and firm, avoiding stress concentration or deformation caused by angle deviation;

[0016] 2. Standardize each component into a threaded connection and a sleeve-type structure to achieve pre-assembly on the ground and rapid on-site installation, simplifying the traditional multi-step fixing process, which can be completed with only basic tools; improve construction efficiency and shorten the construction period; the connection process is quick and convenient, reducing human error and rework.

[0022] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1 and Figure 2 As shown in this embodiment, the hemispherical universal hanger for ceiling joists includes a hanger rod 1, a ball head 2, a ball head cover 3, a ball head seat 4, and a connector 5. The hanger rod is movably connected to the ball head seat via the ball head, the ball head cover covers the outside of the ball head seat, and the connector is fixed to the bottom of the ball head seat. The components are modularly assembled through threaded connections and riveting.

[0024] The lifting rod 1 uses an M12 fully threaded rod body.

[0025] Ball head 2 is a hemispherical structure with an internal threaded interface at the top, and its outer contour radius of curvature matches the inner cavity of ball head seat 4.

[0026] The lower end of the boom 1 is rigidly connected to the threaded interface of the ball head 2 by clockwise screwing.

[0027] like Figure 4 As shown, the ball head seat 4 is an irregularly shaped cast steel part, including a rectangular support plate at the bottom and a hemispherical groove at the top. The curvature of the inner cavity of the groove matches the outer contour of the ball head 2, and a through hole is opened at the top for the lifting rod 1 to pass through; two sets of riveting holes are symmetrically opened at the bottom.

[0028] like Figure 3 As shown, the ball head cap 3 is stamped into a hemispherical shell shape from a 3mm hot-dip galvanized steel sheet, and the curvature of its inner cavity is consistent with the outer contour of the ball head seat 4. A through hole is opened at the center of its top, and the hanger 1 extends to the outside after passing through the through hole.

[0029] The top of the ball head cap 3 is also equipped with a stainless steel nut and a flat washer, and axial pressure is applied to the cap by tightening the nut.

[0030] Connector 5 is a U-shaped stamped part, including a web and two side flanges. The flanges are symmetrically stamped with riveting holes, which are fixed to the bottom riveting holes of the ball head seat 4 with anti-loosening rivets; the web has a keel mounting hole in the center for connecting the keel.

[0031] The working principle of this embodiment is as follows:

[0032] The ball joint and ball joint seat form a spherical sub-mechanism, allowing stepless angle adjustment of the hanger relative to the ball joint seat within a conical space when not locked. This structure can compensate for non-perpendicular installation deviations between the hanger and the keel, adapting to topological changes in curved ceilings.

[0033] When tightening is required, the stainless steel nut is screwed onto the threaded section of the boom extension, and the flat washer presses the ball head cap together. During tightening, pressure is transmitted through the cap to the ball head seat, ultimately locking the ball head into the groove of the ball head seat.

[0034] In this embodiment, the force transmission path is as follows: the hoisting load is transmitted to the ball head via the hoisting rod, and then evenly distributed to the bearing plate of the ball head seat through spherical contact. After locking, the ball head cap forms a covering constraint, preventing the ball head from detaching and enhancing shear strength. Finally, the load is transmitted to the keel through the U-shaped structure of the connector, ensuring continuous and stable force flow.

[0035] like Figure 5 As shown, the construction advantage of this embodiment lies in its standardized threaded connection for pre-assembly on the ground. First, the hanger rod is screwed onto the ball joint; then, the ball joint is fitted into the ball joint seat; finally, the ball joint seat is fixed to the connector, and the ball joint cap is fitted into the hanger rod. During on-site installation, only the component needs to be hoisted to the transfer layer, the nut tightened to lock the ball joint, and then the keel fixed using the connector. The modular design reduces high-altitude work steps and improves installation accuracy.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
