Wherein, the latch keel 2 and the pinch plate 6 can also be other structures matched with each other in the prior art.
The building suspended ceiling structure capable of shortening the distance between the building suspended ceiling structure and the ceiling plate has the following technical advantages:
firstly, the latch keels 2 are installed on the ceiling 1 through the wall connecting pieces 3, and the wall connecting pieces 3 are embedded into the ceiling 1, so that the distance between the ceiling 1 and the buckle plates 6 is obviously shortened, and especially compared with the prior art, the distance between a suspender and a main keel is saved, so that the building ceiling structure is suitable for being used in a low-rise room;
secondly, the first movable part 33 and the second movable part 34 of the wall connecting piece 3 can deflect, when the mounting hole 11 is not strictly vertical, the latch keel 2 can still be horizontal, because the mounting hole 11 is difficult to ensure to be strictly vertical in the actual construction process, if the wall connecting piece 3 does not have the adjusting function, but an adjustable suspender in the prior art is omitted, once the mounting hole 11 is slightly inclined, the mounting of the latch keel 2 is influenced;
in addition, the wall connecting piece 3 has a height adjusting function, so that the height of the latch keel 2 can be conveniently adjusted during installation, and the latch keel 2 can be at a reasonable design height; the adjustable principle of the wall connecting piece 3 is as follows: the elastic tube 325 has elasticity, and contacts with the beads 324, so that the beads 324 can be elastically pushed outwards, when the inner tube 32 is inserted into the expansion tube 31, the beads 324 are pressed against the inner wall of the expansion tube 31, the inner tube 32 is not easy to fall off, and the inner tube 32 can still move up and down at the moment, so that the height adjustment is realized; the bead 324 is arranged at two positions in the expansion tube 31, namely, the bead 324 is arranged in the arc-shaped groove 317, the force applied to the bead 324 is small, and the up-and-down movement of the inner tube 32 is relatively easy; the other is that the beads 324 are outside the arc-shaped groove 317, that is, the inner tube 32 rotates a certain angle, at this time, the accommodating space of the beads 324 is reduced, the beads are closer to the elastic tube 325, the inner tube 32 is clamped more tightly, and a larger force is needed to adjust the height of the inner tube 32; wherein the elastic tube 325 may be an elastic rubber tube. The beads 324 have the benefit of two states: when the latch keel 2 is installed on the second movable member 34 (the tubular member 341 of the second movable member 34 is passed through the circular hole 21 of the latch keel 2 and the lower thread turn 345 is screwed, but the thread turn 345 is not screwed), the inner pipes of the wall connecting members 3 in the whole row are easy to move up and down, the latch keels 2 can be adjusted to a reasonable position (rough adjustment), after the adjustment is completed, the second movable member 34 is rotated to make the beads 324 be separated from the arc-shaped grooves 317, thus, the latch keel 2 can be fixed to the ceiling with the increased clamping force of the beads 324, and the latch keel 2 can be finely adjusted up and down with a large force, and finally the screw ring 345 is tightened, in such a manner, the height can be adjusted, and the installation is more convenient, so that a longer suspender in the prior art can be saved;
the wall connecting piece 3 can be firmly arranged on a ceiling by the tensioning function, and forms powerful support for the latch keels 2 and the buckle plates 6 and the like below the wall connecting piece; the principle of the tensioning function is that after the core tube 35 is inserted, the top of the core tube 35 abuts against the partition 311 through rotation of the core tube 35, the central pull rod 37 penetrates through the core tube 35, and when the nut 373 on the third external thread section 372 at the bottom of the central pull rod 37 is locked step by step, the central pull rod 37 moves downwards, so that the expansion block 36 is pulled downwards, and the matched expansion foot 314 is opened to enable the expansion tube 31 to be tensioned in the mounting hole 11; in the wall connecting piece 3, the core pipe 35 is very critical, and not only plays a role in tensioning, because the top of the core pipe 35 is provided with the second external thread section 351 matched with the screw hole 322, after the core pipe 35 is screwed into the screw hole 322, the core pipe 35 and the inner pipe 32 are connected into a whole, and after tensioning, the core pipe 35 is firmly fixed, so that the inner pipe 32 can not be adjusted up and down, the position of the latch keel 2 is completely fixed, the core pipe 35 can not shift in the using process, the problem caused by aging of the elastic rubber pipe can not occur, and the whole suspended ceiling is in a stable state.
As a further improvement of this embodiment: the bead hole 323 is provided with a rubber ring 329 in a clamping way at the outer side (as shown in figure 11), or the bead hole 323 is in a shape with a large inner part and a small outer part (as shown in figure 12), so that the improvement can ensure that the beads are not easy to fall out of the bead hole and are convenient to install.
In order to meet the requirements of low-rise and high-rise houses, the distance between the ceiling 1 and the buckle plate 6 is preferably not more than ten centimeters.
The building suspended ceiling structure capable of shortening the distance between the suspended ceiling structure and the ceiling plate has the advantages that: compared with the prior art, the main keel and the suspender are saved, the distance between the buckle plate and the ceiling is greatly reduced, and the novel ceiling is particularly suitable for the current residence with the height of 2.9 meters in China; meanwhile, the structure is firm, the installation is convenient, and the practicability is strong.
The above-described embodiments are merely illustrative of the concept of the present invention, and it is obvious that the scope of protection of the patent is not limited to the above-described embodiments.
Various equivalent modifications or additions to the above-described embodiments, which may occur to persons skilled in the art, are intended to be covered by the present patent.
