The hollow shell is characterized in that a first through hole 11 is formed in the center of the bottom surface of the hollow shell, a spiral surface 111 is arranged on the edge of the first through hole 11, and the spiral surface 111 comprises two inclined portions 1111 which are symmetrically distributed by taking the central shaft of the first through hole as a central symmetry axis. The end parts of the inner side wall of the first through hole corresponding to the two inclined parts 1111 are respectively provided with a abdicating groove 1112 for the protrusion 2211 on the hanger to pass through. In use, the support portion is pre-fabricated on the lower surface of the building panel to facilitate assembly during construction.
As shown in fig. 11 to 12, the first connecting structure 2 is used for connecting the support part 1 with the upper end of the support tube 3, and the first connecting structure 2 comprises a cross arm 21, a connecting rod 22 and a lock nut 23;
the connecting part of the connecting rod 22 and the supporting part is provided with a hanger 221, the side wall of the top of the hanger is provided with two protruding parts 2211 which are symmetrically distributed along the axial direction of the connecting rod 22, and the two protruding parts 2211 are respectively contacted with the corresponding inclined parts 1111; namely, the upper part of the hanger is in an arrow shape, the arrow point shape is mainly used for guiding the hanger, and the shoulders at the lower side of the arrow are used for sliding and screwing on the spiral track of the first through hole of the hollow shell. In the assembling process, the top of the hanger penetrates from one side of the first through hole to the other side of the first through hole from the abdicating groove, at the moment, the protruding part is in contact with the inclined part, and the protruding part moves from the lowest point to the highest point of the inclined part through clockwise or anticlockwise rotation, so that the connecting rod and the supporting part are firmer and firmer. The outer surface of the side wall of the middle part of the hanging tool 221 is provided with an external thread 2212, namely a screw rod, which is used for adjusting the height of the cross arm, pushing the cross arm high when the mold is loaded, and lowering the cross arm when the mold is unloaded.

The inner side surface of the other end of the sleeve ring is provided with an internal thread 412;
the guide sleeve 42 comprises a circular ring body 421, an extension 422 and an outer edge 423, the extension 422 is arranged at the inner circle edge of the circular ring body and extends in the direction perpendicular to the circular ring body, the outer edge 423 of the guide sleeve is arranged at the outer circle edge of the circular ring body and extends in the direction perpendicular to the circular ring body, the extension directions of the extension 422 and the outer edge 423 of the guide sleeve are the same, and the annular groove 424 is formed between the extension 422 and the outer edge 423 of the guide sleeve; the distance between the free end of the outer edge of the guide sleeve and the annular body is smaller than the distance between the free end of the extension part and the annular body. The width of the annular groove is adapted to the wall thickness of the support tube.
The lateral wall that the one end of tourus was kept away from to extension 422 has lead angle 4221, plays the guide effect when being convenient for assemble with the stay tube, also reduces rigid impact between the two simultaneously, avoids causing the impaired of stay tube embedding annular groove part, if wear and tear for a long time, can influence the fit clearance grow gradually of stay tube and annular groove, and then influence structural stability. Of course, it is also possible to coat the outer side wall of the free end of the extension with a lubricating material, which further reduces wear. In addition, the middle part of extension has along the hollow out construction 4222 of circumference distribution, under the condition that ensures that structural strength reaches the requirement, can effectively save the consumptive material. In addition, the part of the extension part embedded in the supporting pipe is contacted with the inner side wall of the supporting pipe, so that the supporting effect is realized, the gap between the extension part and the supporting pipe is eliminated, and the connection stability is improved.
The outer side wall of the nut 43 is provided with an external thread 431, namely an external tooth, which is matched with the internal thread 412 at the other end of the lantern ring, and is used for fastening with the lantern ring, so that the nut is ensured to rotate only within a limited range at any time and not fall off. The inner side wall of the nut 43 is provided with an internal thread 432 which is in threaded connection with the threaded rod 52 on the support seat 5. The two ear parts 433 symmetrically arranged are arranged on the outer surface of the side wall of the nut, so that the nut is convenient to adjust.
As shown in fig. 16, a threaded rod protector 434 is welded to the lower surface of the nut 43, and the inner diameter of the threaded rod protector 434 is larger than the outer diameter of the threaded rod to prevent the threaded rod and the nut from being contaminated and ensure the normal use of the threaded rod.
