Abstract
The utility model provides a trough-shaped main keel which is used in the architectural decoration field, and the utility model comprises a fastening groove. The utility model is characterized in that reinforcing ribs (4, 5) are respectively arranged on sides (2, 3) of the main keel, and long strip-shaped connection holes (6, 7) are respectively arranged on the sides (2, 3) of the main keel. The upper plane of the main keel is provided with a long strip-shaped hole (8). The utility model has high strength, and the utility model has convenient leveling, operation, and use.
Description
The utility model relates to a kind of main joist that is used on the building decorating industry, particularly be a kind of grooved main joist.
The grooved keel that are used at present on the building decorating industry are made up of main joist and the rider keel that matches with it.This main joist two sides do not have muscle, intensity difference, and easily distortion, the accent hole of the tying up hook on its bottom surface is circular, suspension hook one end passes circular hole and with nut it is locked in main joist, leans on special tool during installation.Whether putting in place only relies on sensation, can't look at straight, causes diastema easily, inconvenient operation and to adjust the planeness of decorative panel pretty troublesome even hoist cable occurs and serious quality problems such as planeness take place to adjust rider keel on a vertical line; By the circular port location of its both sides, regulate inconvenient operation during the spreading main joist; Catching groove end face on the main joist is
Type, intensity is low or take material.
In view of above reason, the purpose of this utility model is in order to provide a kind of intensity high grooved main joist.Another purpose of the present utility model is for a kind of not only intensity height but also leveling, grooved main joist easy for operation are provided.
The purpose of this utility model is achieved in that catching groove (9) in the utility model, it is characterized in that reinforcing rib (4,5) is arranged on the side (2,3) of main joist (referring to Fig. 1～Fig. 3).
The strip connecting hole is arranged (referring to Fig. 1～Fig. 3), adjusting, positioning action are conveniently on the side of above-mentioned main joist (2,3).
The plane has strip to transfer hole (8) (referring to Fig. 1～Fig. 3) on the above-mentioned main joist, can be with hanging in the suspension hook the shape of making as shown in Figure 4, it is hung crooked end is passed strip transfer the hole and be fixed on the main joist and slidably hoist cable is housed on the other end, there is adjusting nut the lower end of hoist cable, so regulate the planeness of decorative panel easily.
The end face (10) of above-mentioned catching groove (9) is straight plane (referring to Fig. 1, Fig. 4), intensity height or material-saving.
The utility model intensity height, flexural strength can improve more than 15%, and the spreading steering capability is good, have remedied the error that the technology cumulative limit produces when general assembly; Leveling, easy for operation, material-saving, the energy economical with materials is more than 19% under the constant situation of flexural strength.Widely applicable, can be supporting with dissimilar rider keels.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the utility model scheme of installation.
Referring to Fig. 1～Fig. 3, be symmetrically distributed with to evagination reinforcing rib 4,5 on the two sides 2,3 of the utility model main joist 1, be symmetrically distributed with several or this bar shaped connecting hole 6,7 of dozens of.End face at main joist has several (or dozens of) strips to transfer hole 8.The end face 10 of catching groove 9 is straight plane.
Referring to Fig. 4, during the spreading main joist, spreading connector 11 is placed two main joists that need spreadings respectively, pass strip connecting hole on the two sides with connector again and be located and connect lengthening.When suspension hook 12 is installed, the other end transferring 13 the lower end hooking strip from the end face of main joist the hole to penetrate the main joist the hanging in the suspension hook 12 and hang is equipped with an end moving up and down can be contained in hoist cable 14 on the ceiling, adjusting nut 15 is arranged at the bottom of hoist cable 14, so just can regulate the planeness of decorative panel.
