The support frame system is generally built by criss-cross keel sectional materials at present. A common connecting structure with a clamping type framework, such as a ceiling keel structure with a main light and a secondary dark disclosed in chinese patent 200820176329.3, is mainly composed of a main keel and a secondary keel. The main joist is provided with a plurality of holes for hanging the main joist and at least one rectangular hole for fastening the auxiliary joist. Pull grooves are respectively arranged at the head end and the tail end of the auxiliary keel. The false keel is clamped in the rectangular hole of the main keel through the pull groove, so that the connection between the false keel and the main keel is realized. However, the buckling position between the cross runners and the main runner is limited by the position of the rectangular hole, if the position of the cross runner on the main runner needs to be adjusted, the main runner needs to be detached from a ceiling system and then the rectangular hole is punched on the main runner again, the operation is complicated, and the cross runners cannot be flexibly positioned at any position of the main runner.

In addition, the common loose joint formula fossil fragments connection structure in addition, including main joist, triangle fossil fragments and square decoration panel, two are adjacent be provided with many verticals between the main joist and interval arrangement the triangle fossil fragments, adjacent two be formed with the installation between the triangle fossil fragments the installation window of square decoration panel, four outward flanges of square decoration panel are provided with the limit of bending respectively, a pair of limit of bending in the left and right of square decoration panel is connected adjacent the arranging respectively to the joint on the triangle fossil fragments. The main joist with the cross connection department of triangular keel is provided with hangs the piece, it sets up the pothook to hang the lower tip of piece, the pothook is used for the joint triangular keel, the upper end that hangs the piece is provided with the kink, the kink is used for articulate on the main joist. The construction of the hanger is described in detail in chinese patent 201110333161.9. Similar solutions are also described in chinese patents 201010616220.9 and 201020154098.3. It can be seen that in such a connection scheme through the hanging piece, the hanging piece is connected with the triangular keel and the main keel, but only connected together, and a stable connection relationship is not formed between the hanging piece and the triangular keel, so that the skeleton system is loose and indefinite. The requirement of earthquake resistance cannot be met at all, once an earthquake occurs, the hanging piece is very easy to separate from the main keel or the triangular keel, so that the whole framework system is scattered and falls off, and passerby passing by is injured by crashing.

Detailed Description

The structure of the stable installation type suspended ceiling system applying the technical scheme of the invention is further explained by combining the attached drawings.

As shown in fig. 1, 2 and 3, a novel stable ceiling system includes a stable ceiling structure, specifically including a main beam 1, and when viewed from a cross section, the main beam 1 includes a main beam base 11 for connecting to a suspension rod 4 and a first decoration material joint portion 12 extending from the main beam base 11, the first decoration material joint portion 12 is used for supporting a ceiling decoration material, in this embodiment, the ceiling decoration material is a decoration panel 2, and a panel edge of the decoration panel 2 is supported on the first decoration material joint portion 12. A main beam connection slot 110 with a downward notch is also arranged on the main beam base 11. For the sake of convenience of distinction from the girder connection socket to be mentioned below, the girder connection socket 110 is named a third girder connection socket 110. The third main beam connection slot 110 is located on the first decorator coupler 12. The decorative panel is characterized by further comprising a positioning spring piece 3, wherein the positioning spring piece 3 is used for enabling the head end 311 to be combined with the third main beam connecting slot 110 and enabling the tail end 321 to elastically press against the decorative panel 2 in the installation state, and elastic compression deformation is generated in the vertical direction under the compression action of the third main beam connecting slot 110 and the decorative panel 2, so that downward pressing acting force for fixing the decorative panel 2 on the first decorative material combining part 12 is formed. The third main beam connection slot 110 forms the spring piece combining portion for combining with the head end 311 of the positioning spring piece 3.

Wherein a third main beam connection slot 110 with a downward-arranged notch is further provided on the main beam base 11, and the above-mentioned feature defines that in the ceiling system, the notch of the third main beam connection slot 110 is arranged toward the ground. Thus, the head end 311 of the positioning spring plate 3 needs to be inserted into the third main beam connection slot 110 from bottom to top. When the head end 311 of the positioning spring piece 3 is inserted into the third main beam connecting slot 110, the head end 311 of the positioning spring piece 3 is elastically compressed and deformed to have a tendency of extending upward, so that the head end 311 can approach the bottom 1102 of the third main beam connecting slot 110 as much as possible and cannot easily get over the slot sidewall 1101 of the third main beam connecting slot 110 to be separated from the third main beam connecting slot 110.

The positioning spring pieces 3 are elastically compressible and deformable in the vertical direction under the compression action of the third main beam connecting slot 110 and the decorative panel 2, that is, the positioning spring pieces 3 are provided with an elastic structure capable of being appropriately expanded and contracted in the vertical direction, and the amount of expansion and contraction in the vertical direction can be flexibly adjusted in accordance with the vertical distance between the third main beam connecting slot 110 and the decorative panel 2 supported on the first decorative joint 12. Specifically, as shown in fig. 3, the positioning spring plate 3 is a substantially zigzag sheet metal component, and includes an upper elastic leg 31, a lower elastic leg 32, and a connecting arm 33 connected between the upper elastic leg 31 and the lower elastic leg 32, where the upper elastic leg 31 includes a head end 311 for being combined to the third main beam connecting slot 110, and a bent portion 312 disposed between the head end 311 and the connecting arm 33, and the bent portion 312 is used for being pressed by a hand to drive the head end 311 of the upper elastic leg 31 to move down so as to be combined to the third main beam connecting slot 110; the lower elastic support leg 32 is used for transversely and flatly leaning on the decoration panel 2 to provide stable support for the positioning spring piece 3. According to the above technical solution, in the process of installing the ceiling system, the plate edge of the decorative panel 2 is firstly supported on the first decorative material combining portion 12, then the lower elastic support leg 32 of the positioning spring piece 3 is placed on the decorative panel 2, and the hand applies a downward pressure to the upper elastic support leg 31 by pressing the bending portion 312 downward to make the positioning spring piece 3 generate compressive elastic deformation so that the head end 311 moves downward and is inserted into the third main beam connecting slot 110. The lower elastic legs 32 are stressed and deformed to be transversely and flatly leaned on the decorative panel 2 when the bending part 312 is pressed down by human hands, so that stable support is provided for the positioning spring pieces 3. Of course, in other embodiments, the lower spring leg 32 may already lie transversely flat against the trim panel 2 before being stressed.

According to the above technical solution, firstly, since the notch of the third main beam connecting slot 110 is arranged downward, and the positioning spring piece 3 is matched with an elastic structure which properly extends and contracts in the vertical direction, the head end 311 of the positioning spring piece 3 can be stabilized by the third main beam connecting slot 110, and the head end 311 is prevented from easily separating from the third main beam connecting slot 110 to damage the fixing effect of the positioning spring piece 3 on the decorative panel 2. Therefore, the positioning structure of the positioning spring piece 3 is simple and reliable. Secondly, because the positioning spring pieces 3 can be elastically compressed and deformed in the vertical direction under the compression action of the third main beam connecting slot 110 and the decoration panel 2, this is advantageous in view of the instability of the vertical distance between the third main beam attachment slot 110 and the decorative panel 2 supported by the first decorative material joining portion 12 due to the dimensional errors such as the dimensional errors in the manufacture of the third main beam attachment slot 110, the dimensional errors in the manufacture of the decorative panel 2, and the dimensional errors in the manufacture of the first decorative material joining portion 12, the positioning spring pieces 3 can reliably press and fix the decoration panel 2 on the first decoration material combination part 12, so that the stability of the decoration panel 2 is optimized, and the requirement on the manufacturing precision of the suspended ceiling main beam 1 can be reduced.

As shown in fig. 2, a connection groove group, specifically three main beam connection grooves, is disposed at the top of the main beam base 11, and the connection groove group is disposed on the first decorative material combining portion 12 and the third main beam connection groove 110, so that the structural strength of the main beam base 11 can be strengthened by the connection groove group.

According to the technical scheme, the layout positions and the notch orientations of the three main beam connecting slots (112, 112 ', 113) are different, so that the first support arm 91 and the suspension rod 4 of the transition connection piece 9 can be flexibly and selectively connected to any one of the three main beam connecting slots (112, 112', 113) according to the field installation condition, the ceiling structure and other factors. Specifically, in the present embodiment, the first main beam connection slot 112 has a notch facing to the right side, and the first main beam connection slot 112 'has a notch facing to the left side, and the ceiling main beams 1 in the front-rear alignment or corner position are connected together by means of a connection bracket inserted into the first main beam connection slots (112, 112').

According to the technical scheme, the groove 115a can be utilized to enrich the appearance of the suspended ceiling main beam 1a, so that the stereoscopic impression of the suspended ceiling system is enhanced; alternatively, the cavity of the recess 115a may be used to store functional components, such as speakers, suction fans, lights, etc., to enrich the functionality of the ceiling system. In this embodiment, a mounting region 1150a for positioning the light emitter is provided on a groove wall of the groove 115 a. The LED lamp further comprises a light-transmitting lamp shade 6, and the light-transmitting lamp shade 6 covers the groove 115 a. The outer surface 60 of the light-transmitting cover 6 is flush with the outer surface 120a of the first decorative material joining portion 12 a.
