Description

TECHNICAL FIELD

[0001] The utility model belongs to ceiling installation technical field, concretely relates to a cross connecting piece for ceiling joist installation. BACKGROUND

[0002] The existing two mutually perpendicular ceiling joists are usually connected by setting a flange sheet on the end of one joist, and then locking the flange of the end of the joist on the side wall of the other mutually perpendicular joist through a bolt assembly, so as to realize the connection of the two longitudinal and transverse intersecting joists. The whole process is inconvenient to install and time-consuming.

[0003] The applicant submitted a utility model patent application with the application number 202421775904.7 on July 25, 2024, which discloses a connection structure of a ceiling joist, simplifying the connection of two longitudinal and transverse intersecting joists. However, the connection structure disclosed in the utility model patent can only connect two joists at the same time, i.e., it can only connect two ceiling modules at the same time, which cannot meet the demand of connecting four ceiling joists at the corner of a ceiling module at the same time. SUMMARY

[0004] In order to solve the above-mentioned problems existing in the prior art, the utility model aims to provide a cross connecting piece for ceiling joist installation.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] A cross connecting piece for ceiling joist installation, comprising a channel steel base body, the channel steel base body is provided with a transverse clamping groove at both ends along the length direction; the side wall of the channel steel base body is provided with a clamping piece body formed by bending along the width direction; the transverse clamping groove and the clamping piece body are respectively used for connecting two groups of mutually perpendicular joists.

[0007] As an option, the clamping piece body is punched and formed by bending through the channel steel base body.

[0008] As an option, the material of the channel steel base body is selected from light steel or aluminum.

[0009] The utility model has the beneficial effects that:

[0010] This invention provides a cross-shaped connector for installing ceiling joists, comprising a channel steel base. Horizontal snap-fit ​​grooves are provided at both ends of the channel steel base along its length, allowing connection of ceiling joists on two ceiling modules at both ends of the channel steel base by snapping these grooves into the ceiling joists. Snap-fit ​​pieces are also provided along the width of the channel steel base, connecting the ceiling joists on both sides of the channel steel base in the width direction. This invention can simultaneously connect ceiling joists at both ends of the channel steel base along its length and on both sides of its width, connecting up to four ceiling modules at once, overcoming the limitation of existing connection structures that can only connect two mutually perpendicular joists simultaneously. Furthermore, the snap-fit ​​pieces along the width of the channel steel base are formed directly by bending the side wall of the channel steel base, simplifying processing, increasing production efficiency, and making them readily available and easy to use.

[0011] Fig. 1 This is a schematic diagram of the structure of this utility model.

[0012] Fig. 2 and Fig. 3 This is a schematic diagram showing the connection relationship between the snap-fit ​​plate and the ceiling joists.

[0013] In the diagram: 1-channel steel base, 2-horizontal connecting groove, 3-clamping plate, 4-ceiling keel. Detailed Implementation

[0014] In this embodiment, as Figs. 1-3 The diagram shows a cross-shaped connector for installing ceiling joists. It includes a channel steel base 1, with transverse snap-fit ​​grooves 2 at both ends along its length. The sidewalls of the channel steel base 1 are provided with bent snap-fit ​​pieces 3 along their width. The transverse snap-fit ​​grooves 2 and snap-fit ​​pieces 3 are used to connect two sets of joists that are perpendicular to each other. The snap-fit ​​pieces 3 are formed by punching and bending from the steel base 1.

[0015] Specifically, during processing, an I-shaped punching tool is used to first punch an I-shaped hole on the side wall of the channel steel base 1, thus leaving two independent pieces on the side wall of the channel steel base 1; then the pieces punched from the channel steel base 1 are bent 90° outward to form the snap-fit ​​piece 3.

[0016] This utility model, by providing transverse snap-fit ​​grooves 3 at both ends of the channel steel base 1 along its length, allows the transverse snap-fit ​​grooves 3 to snap into the ends of the ceiling joists 4, thus enabling the connection of the ceiling joists 4 on two ceiling modules at both ends of the channel steel base 1 along its length; and by providing snap-fit ​​pieces 3 along the width of the channel steel base 1, the snap-fit ​​pieces 3 can be used to connect the ceiling joists 4 on both sides of the channel steel base 1 along its width (e.g., Fig. 2 and Fig. 3The utility model discloses can connect the furred rafter 4 of the length direction both ends and width direction both sides of the section steel base body 1 simultaneously, can connect four furred ceiling modules simultaneously at most, has overcome the defect that the prior art connecting structure can connect only two mutually perpendicular furred rafters simultaneously. Meanwhile, the clamping piece body of the width direction of the section steel base body 1 is formed by the side wall of section steel base body 1 directly through blanking and bending, and the processing is simple, the production efficiency is high, is easy to obtain and convenient to use.

[0017] Optionally, the material of the section steel base body 1 is selected from light steel or aluminum.
