Set up hoist and mount connecting piece 72 is in order to have certain position adjustment surplus along furred ceiling fossil fragments 4 length direction (be right-and-left direction promptly), and on the one hand can reply hoist and mount expansion bolt 8 fixed connection and have little size deviation in the position of basic top, and on the other hand can also adjust the hunch-up degree of whole furred ceiling by a small margin, because the furred ceiling is close to the more condition emergence that the center department collapses downwards that appears more easily, consequently can be through adjusting along fossil fragments length direction the position of hoist and mount connecting piece 72, adjusted hoist and mount expansion bolt 8 the hookup location of furred ceiling on the right-and-left direction promptly, can set up the hoist and mount expansion bolt 8 that is close to the furred ceiling intermediate position slope by a small margin, thereby make it right furred ceiling fossil fragments 4 form the oblique application of force state that draws of a small margin, can effectively prevent the problem that the furred ceiling from collapsing downwards.

In general, the locking structure 73 is required to be provided in two, spaced apart positions, i.e. a left-right position, the locking structure 73 comprises a locking block 731, a locking fastener 732, the locking block 731 is generally square in structural shape, one part of which is supported on the hoisting connecting piece 72, the other part of which is supported on the supporting base 71, the top end of the locking fastener 732 penetrates and is fixedly connected with the locking block 731, the bottom end penetrates and is fixedly connected with the supporting base 71 and the beam part 42, the locking fastener 732 may be specifically configured as a screw rod with two ends respectively sleeved with a nut, and the nut is screwed after the two ends of the screw rod penetrate through the screw rod, so that the hoisting connector 72 is vertically clamped by the supporting base 71 and the locking block, thereby completing the position locking of the hoisting connector 72, the lifting connector 72 can be slid along the support base 71 to adjust its position before the nuts are tightened.

More specifically, the hoisting connector 72 includes a suspended ceiling base portion 721 erected on the supporting base 71, and two stopping portions 722 connected to the suspended ceiling base portion 721. The ceiling base portion 721 and the stopping portion 722 are both of a flat plate structure and are of an integral structure, the ceiling base portion 721 is horizontally arranged, and the stopping portion 722 is substantially vertically arranged. The two ceiling keels 4 of the stopping portion 722 are arranged at intervals in the length direction and are used for being respectively abutted against the two locking blocks 731, so that the two locking blocks 731 can clamp the hoisting connecting piece 72 in the horizontal direction, and the looseness of the hoisting connecting piece 72 in the left and right directions can be avoided. The locking blocks 731 are provided with kidney-shaped holes which penetrate through up and down and extend along the length direction of the ceiling keel 4, the top ends of the locking fasteners 732 penetrate through the kidney-shaped holes, when the locking blocks 731 are installed, the top ends of the locking fasteners 732 can not be locked with the locking blocks 731, so that the locking blocks 731 integrally press the hoisting connecting piece 72 and can also slide in the left and right directions relative to the locking fasteners 732, one locking block 731 is pushed to complete position adjustment, after the locking block 731 and the top ends of the locking fasteners 732 are fixed, the other locking block 731 is pushed, the two locking blocks 731 are abutted against the corresponding abutting parts 722 to complete horizontal clamping, and after the locking blocks are fixed, vertical clamping is completed, namely, the hoisting connecting piece 72 is locked on the supporting base.

As for the support base 71, more specifically, the support base 71 includes a support base 711 supported on the cross beam portion 42 and supported by the locking block 731, and two support sides 712 connected to the support base 711, the support base 711 and the support sides 712 each having a flattened plate-like structure and being an integral structure, so that the support base 71 as a whole has a U-shaped structure. The two support sides 712 extend vertically and are spaced apart widthwise of the ceiling grid 4, i.e., in tandem. The top edge of the supporting side part 712 is divided into three sections, the middle section is an erection section 712-i for erecting the ceiling base 721, the two ends connected with each other are supporting sections 712-j for supporting the locking blocks 731, the ceiling base 721 is erected on the erection sections 712-i of the two supporting side parts 712, and the two locking blocks 731 are supported on the supporting sections 712-j of the two supporting side parts 712. The structure that support pedestal 71 is whole to be the U type makes all there is certain space between furred ceiling basal part 721 and the support basal part 711 can be convenient for from furred ceiling basal part 721 below with hoist and mount expansion bolt 8 and furred ceiling basal part 721 fixed connection, consequently can run through furred ceiling basal part 721 with hoist and mount expansion bolt 8 and come both fixed connection, the junction site and be located the bottom surface of furred ceiling basal part 721, this kind runs through fixed connection's mode again and can strengthen hoist and mount expansion bolt 8 and hang up the intensity of furred ceiling fossil fragments 4, does benefit to the overall stability who improves the furred ceiling.

In addition, it is noted that the portion of the ceiling base 721 that can be supported by the locking block 731, the support sections 712-j, are all tilted, and the magnitude of the tilt is the same. When the lifting connecting piece 72 slightly shifts back and forth, one locking block 731 is also shifted, and the horizontal height of the locking block 731 is increased, so that the distance between the locking block 731 and the supporting base 711 is increased, and the dead force of the top end of the locking fastener 732 on the locking block 731 is increased, thereby preventing further position shift.

The support base 71 further includes slide plates 713, the slide plates 713 are sandwiched between the support base 711 and the cross member portion 42, and the slide plates 713 are upwardly protruded along both side edges in the width direction of the ceiling runner 4 and supported at the corners of the cross member portion 42 and the side standing portions 41. The provision of the sliding pad 713 may leave a gap between the support side 712 and the side standing portion 41 of the ceiling runner 4, and since the support base 71 is installed from one end of the ceiling runner 4 and slides to a suspended position, the sliding pad 713 may reduce a contact area between the support base 71 and the ceiling runner 4 so as to be more easily slid, and since the sliding pad 713 is supported at corners of the beam portion 42 and the side standing portion 41, a limit effect may be also exerted, and in addition, the surface of the sliding pad 713 may be made smoother by a deep polishing process.

The ceiling connecting member 72 further includes two ceiling side portions 723 connected to the ceiling base 721 and spaced apart from each other in the width direction of the ceiling runner 4, that is, the two ceiling side portions 723 are in tandem and have a flat plate-like structure, the ceiling side portions 723 extend upward from the ceiling base 721, the top ends of the ceiling side portions 723 have third bending portions 7231 bent inward and engaged with the first bending portions 411, the structure between the runner connecting member 6 and the ceiling runner 4 is similar to that described above, and the description of the functions is omitted. In addition, a gap is formed between the ceiling side portion 723 and the side standing portion 41, and the gap is also a buffer space for aging and deformation after a long time.

The suspended ceiling side portions 723 and the side edges of the stopping portions 722 are connected, so that the two suspended ceiling side portions 723 and the stopping portions 722 form a surrounding structure, namely, the hoisting connecting piece 72 is in a square structure, and the overall structural strength of the hoisting connecting piece is improved.
