Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1 and 2, the assembled ceiling structure disclosed by the invention comprises an installation frame 4 fixedly arranged on the peripheral wall, a plurality of keels 1 and a plurality of grids 2, wherein the keels 1 are vertically arranged in the installation frame 4, and the number of the keels 1 is smaller than that of the grids 2. The opening that keel 1's cross section was personally submitted door style of calligraphy setting and keel 1 is towards ground, and many 1 mutual intervals of fossil fragments and parallel arrangement, keel 1 is provided with many jib 3 that are fixed in the ceiling wall body along its length direction interval, connects 1 middle part of fossil fragments through jib 3 to avoid keel 1 middle part undercut under the action of gravity, improve keel 1's installation intensity. A plurality of bars 2 interval parallel arrangement in fossil fragments 1 below, and be equipped with installation component 5 between bar 2 and the fossil fragments 1 to be connected bar 2 and fossil fragments 1, with the installation intensity of reinforcing bar 2.
Referring to fig. 1 and 3, the number of groups of installation component 5 corresponds the setting with the radical of fossil fragments 1, and every group all includes the closure 52 with fossil fragments 1 parallel arrangement and a plurality of pendants 51 along the setting of closure 52 length direction interval, and the number of pendant 51 equals with the radical of bars 2 and with bars 2 fixed connection, and the closure 52 slides and sets up in fossil fragments 1 inboard, and can with fossil fragments 1 fixed connection after the closure 52 slides. When the locking piece 52 is fixed with the keel 1 after sliding, the hanging piece 51 is hung with the locking piece 52, so that the connection between the grid 2 and the keel 1 is realized.
Referring to fig. 3 and 4, in order to facilitate the locking piece 52 to slide in the keel 1, the length of the locking piece 52 is smaller than that of the keel 1, the baffles 11 are arranged at the openings at the two ends of the keel 1, the space between the two baffles 11 is smaller than that of the locking piece 52, when one end of the locking piece 52 enters between the keel 1 and the baffles 11, the other end of the locking piece 52 enters between the keel 1 and the baffles 11 through the sliding locking piece 52, and therefore the locking piece 52 slides on the baffles 11. In order to facilitate the hanging connection between the fixing piece and the locking piece 52, the section of the hanging piece 51 is C-shaped, and the opening of the hanging piece 51 faces one side of the grid bar 2, namely the opening direction of the hanging piece 51 is vertical to the length direction of the grid bar 2; the locking element 52 comprises a connecting plate 521 connected with the keel 1 and a plurality of hitching plates 522 fixedly arranged on the inner side of the connecting plate 521, wherein the hitching plates are arranged at the opening of the connecting plate 521 and close the opening of the connecting plate 521. Before installing the grid 2, the locking piece 52 slides towards the end part of one end of the keel 1, so that the hanging plate 522 is staggered with the hanging piece 51; after the grid 2 is installed, the locking element 52 is slid toward the inner side of the hanger 51, so that the hanging plate 522 is placed in the middle of the hanger 51, and the two are in a hanging state.
Referring to fig. 3, in order to improve the connection stability between the grid 2 and the keel 1, the openings of two adjacent hanging pieces 51 on the same grid 2 face opposite directions, so that when the hanging pieces 51 are hung with the locking pieces 52, the locking pieces 52 do not tend to turn over to one side because the openings of the hanging pieces 51 are the same. Meanwhile, in order to ensure that the installation components 5 are arranged identically and avoid the type distinction of the keel 1 with the locking piece 52 during installation, the sliding directions of the locking pieces 52 on two adjacent keels 1 are opposite, so that the lengths of the locking pieces 52 are equal.

For making things convenient for fossil fragments 1 and connecting lath 521 to be connected with jib 3, the one end that jib 3 deviates from the ceiling wall body is equipped with external screw thread 31, and jib 3 runs through behind fossil fragments 1 and the connecting lath 521 threaded connection have a nut 33, and jib 3 is located the upper end of external screw thread 31 and is equipped with fixed be equipped with the conflict ring 32, through the threaded connection between nut 33 and the jib 3, under the combined action of nut 33 and conflict ring 32 for fossil fragments 1 are fixed on jib 3 with connecting plate 522.
Referring to fig. 3 and 4, the keel 1 is provided with a plurality of through holes 12 at intervals along the length direction thereof, and in order to facilitate the threaded connection of the nuts 33 on the hanger rods 3, the through holes 12 are all arranged in the gaps between two adjacent grid bars 2, and the distance between two adjacent grid bars 2 is equal to the width of the grid bars 2; the hanger bar 3 passes out of the keel 1 through the through hole 12, and the diameter of the through hole 12 is smaller than that of the nut 33. In order to ensure the stability of the connection between the locking element 52 and the keel 1 after sliding and lifting, the connecting plate 521 is provided with a plurality of fixing bolts 53 at intervals along the length direction thereof, the fixing bolts 53 penetrate through the keel 1 through the through holes 12 and are in threaded connection with fixing nuts 54, and the keel 1 and the locking element 52 are fixedly connected through the matching of the fixing nuts 54 and the fixing bolts 53. To ensure that the fixing bolt 53 does not interfere with the sliding of the locking element 52 within the keel 1, the height of the fixing bolt 53 is slightly less than the distance that the locking element 52 moves up.
Referring to fig. 4, in order to avoid the tendency that the grid 2 inclines to one side due to the displacement between the hanging member 51 and the hanging plate 522 when the locking member 52 is fixed to the keel 1, the upper end surface of the hanging plate 522 is provided with a plurality of insertion blocks 5221, in this embodiment, the number of the insertion blocks 5221 is three, the central connecting line of the three insertion blocks 5221 is triangular, the hanging member 51 is provided with an insertion hole 511 corresponding to the insertion block 5221, the insertion block 5221 is in insertion fit with the insertion hole 511, and the size of the insertion hole 511 is slightly larger than that of the insertion block 5221, so that the insertion of the insertion block 5221 and the insertion hole 511 is facilitated.
Referring to fig. 2 and 4, flanges 21 are outwardly turned at two ends of the grid bar 2, connecting bolts penetrate through the flanges 21, and the connecting bolts are in threaded fit with the mounting frame 4, so that the grid bar 2 is fixedly connected with the mounting frame 4. In a similar way, the two ends of the keel 1 are also provided with folded edges 13 similar to the two ends of the grid bars 2, and the keel 1 is fixedly connected with the installation frame 4 through the thread fit between the bolts and the installation frame 4. For the installation of making things convenient for fossil fragments 1 and bars 2, the lower extreme inner wall of installation frame 4 can be dismantled and be equipped with flange 41 that the cross-section is the L type, and the interval between two relative flanges 41 is less than the length that corresponds fossil fragments 1 that need install or the length of bars 2, and flange 41 is formed by modes such as expansion bolts or riveting concatenation with installation frame 4 by a plurality of L type angle steel. When the keel 1 and the grid 2 are installed, the keel 1 and the grid 2 can be placed on the retaining edge 41 in advance; after the grid 2 and the installation frame 4 are fixedly connected, the lower section of the grid 2 is abutted against the flange 41, so that the grid 2 and the keel 1 are conveniently installed on the installation frame 4, and the stability of the installation of the grid 2 on the installation frame 4 is improved.
