At present, the connection of the main structural column rib 1 of the building and the transverse rib 11 of the cross beam is mostly connected through binding, so that the labor intensity is high, the efficiency is low, and the consistency and the reliability are insufficient. During construction, the transverse rib 11 is inserted into the main rib 1 in general and is perpendicular to the main rib 1, and the transverse rib 11 and the main rib 1 are crossed, but in order to ensure the strength of the transverse rib 11, the main rib 1 and the transverse rib 11 are bound together, and when the transverse rib 11 and the main rib 1 are crossed, the construction space is relatively small, and basically enough space is not available for binding the main rib 1 and the transverse rib 11, so that the transverse rib 11 is conveniently connected to the upper end of the main rib 1, and the upper end of the main rib 1 is provided with the limiting frame 6 and the fixing mechanism 7.

Wherein, the quantity of spacing frame 6 is the same with the group number of crossbeam muscle, spacing frame 6 includes fixed sleeve 61, connecting rod 62 and locating piece 63, fixed sleeve 61 sets up to sixteen, the specific quantity of fixed sleeve 61 is confirmed according to the quantity of crossbeam owner muscle 1 when actual construction, slip respectively cup joints on the lateral wall of owner muscle 1 and fixed muscle 3, the lateral wall fixedly connected with inserted bar of fixed sleeve 61, the trepanning has all been seted up at the both ends of connecting rod 62, make the both ends of connecting rod 62 cup joint respectively on the inserted bar lateral wall of two adjacent fixed sleeve 61 through the trepanning. The outer side wall of the inserted link is provided with a sliding hole, the positioning block 63 is slidably inserted into the sliding hole, a second elastic piece 631 is further installed in the sliding hole, the second elastic piece 631 is arranged as a spring, and the second elastic piece 631 applies elastic force to the positioning block 63, so that one end of the positioning block 63 slidably extends out from the orifice of the sliding hole. The outer side wall of the connecting rod 62 is provided with a positioning hole, the positioning hole is communicated with the sleeve hole, the sleeve hole of the connecting rod 62 is provided with a round table-shaped hole, therefore, the side wall of the cross section of the sleeve hole is an inclined plane, after the connecting rod 62 is sleeved on the outer side wall of the inserted rod, the side wall of the sleeve hole applies pressure to one end of the positioning block 63, the positioning block 63 is pressed into the sliding hole, after the sleeve hole of the connecting rod 62 is completely sleeved on the inserted rod of the fixed sleeve 61, the positioning block 63 is aligned with the positioning hole of the connecting rod 62, and the positioning block 63 subjected to the elastic force of the second elastic piece 631 stretches out of the sliding hole to be clamped in the positioning hole of the connecting rod 62, and at the moment, the connection of the fixed sleeve 61 and the connecting rod 62 is completed. Of course, the connection between the fixing sleeve 61 and the connecting rod 62 is not limited to the positioning block 63, and the sliding hole of the inserting rod can be emptied, and after the connecting rod 62 is sleeved on the outer side wall of the inserting rod, the positioning hole of the connecting rod 62 is aligned with and communicated with the sliding hole of the inserting rod, and at this time, a bolt can be inserted into the sliding hole and the positioning hole to prevent the connecting rod 62 from being separated from the fixing sleeve 61.

As shown in fig. 14, the outer side wall of the fixing sleeve 61 is connected with a fixing screw 611 in a threaded manner, after the fixing sleeve 61 is sleeved on the outer side wall of the main rib 1 or the fixing rib 3 and the position of the fixing sleeve 61 is determined, the fixing screw 611 is screwed so that one end of the fixing screw 611 extends into the fixing sleeve 61, and one end of the fixing screw 611 contacts the outer side wall of the main rib 1 or the fixing rib 3. Taking the main rib 1 as an example, the fixing screw 611 is screwed, the friction coefficient between the fixing screw 611 and the main rib 1 is increased, and the fixing sleeve 61 is fixed on the main rib 1 through damping.

As shown in fig. 12, the limit frame 6 is provided in a rectangular frame structure, the connecting rod 62 can be replaced according to the distance between the main rib 1 and the fixing rib 3, and after the fixing sleeve 61 is fixed on the outer side walls of the main rib 1 and the fixing rib 3 through the fixing screw 611, the limit frame 6 is made to act like a stirrup 2. At this time, the position of the longitudinal main bar 1 or the fixing bar 3 is kept stable during the concrete pouring process by the limit frame 6. The upper end of the main rib 1 or the fixed rib 3 is prevented from moving in the concrete solidification process by the limiting frame 6, so that the main rib 1 or the fixed rib 3 is ensured to be arranged accurately according to the design requirement, and the bearing capacity and the performance of the whole structure of the upright post are ensured. In the concrete elements of the column, the stop boxes 6 provide lateral restraining forces that help to promote the shear capacity of the structure, helping the concrete resist lateral compressive forces and distortions.

As shown in fig. 11 and 12, the fixing mechanism 7 includes a slide bar 71, a slide sleeve 72 and a pressing bar 73, wherein the slide bar 71 is located above the two connecting rods 62 on both sides of the limit frame 6, and as shown in fig. 13, the two slide bars 71 and the connecting rods 62 are combined into a triangle structure. As shown in fig. 12, two symmetrical fixing mechanisms 7 located on the same horizontal plane are set as a group of fixing pieces, two compression bars 73 of one side fixing mechanism 7 are set as four, two sliding sleeves 72 are fixedly connected to the outer side wall of one compression bar 73, the sliding sleeves 72 on the two compression bars 73 are symmetrically set, and the sliding sleeves 72 are in sliding sleeve connection with the outer side wall of the sliding bar 71.

After the limit frame 6 is installed, as shown in fig. 10 and 11, the transverse bar 11 is slidably inserted between the main bar 1 and the included angle of the slide bar 71. As shown in fig. 11 and 12, by controlling the two compression bars 73 to be separated from each other, the sliding sleeve 72 is driven to slide downwards on the outer side wall of the sliding bar 71, and after the compression bars 73 contact the transverse bar 11, the main bar 1, the sliding bar 71 and the compression bars 73 are clamped on the outer side wall of the transverse bar 11 in a triangular structure. In order to increase the friction coefficient of the main rib 1, the slide bar 71 and the compression bar 73 to the transverse rib 11, the transverse rib 11 is further fixed through damping, and the compression bar 73 is connected with a control frame 74. As shown in fig. 15, an adjusting cylinder 741 is disposed between the control frames 74 of the two compression bars 73 in the fixing mechanism 7, that is, two symmetrical threaded holes are respectively formed at two ends of the adjusting cylinder 741, and the adjusting cylinder 741 is connected to the two control frames 74 through the threaded holes. When in use, the two control frames 74 can be driven to synchronously move (far away from each other or close to each other) by rotating the adjusting cylinder 741, and after the two control frames 74 are far away from each other, the pressing rod 73 can be pressed on the upper end of the transverse rib 11. By screwing the adjusting cylinder 741, the pressure applied by the compression rod 73 to the transverse rib 11 is increased, and then the transverse rib 11 is clamped and fixed through the main rib 1, the sliding rod 71 and the compression rod 73, so that the connection of the transverse rib 11 and the main rib 1 is completed.

Manual ligations are relatively inefficient compared to mechanical attachments. Under the condition of intense engineering progress requirements, manual binding needs a certain technical content and can become a bottleneck of engineering progress. And spacing frame 6 and fixed establishment 7 are prefabricated structure, when the installation, only need adopt the cover (cup joint spacing frame 6 on main muscle 1 and fixed muscle 3), revolve (screw fixing screw 611), insert (peg graft horizontal muscle 11 in the contained angle department of main muscle 1 and slide bar 71), change (rotate a section of thick bamboo 741 and make depression bar 73 downwardly moving) four simple operations can fix horizontal muscle 11 on main muscle 1, consequently, adopt spacing frame 6 and fixed establishment 7 fixed horizontal muscle 11 on main muscle 1 can increase work efficiency, reduce the work degree of difficulty, reduce workman's work burden. The quality of manual ligation is largely dependent on the skill and experience of the worker. There may be differences in lashing quality from worker to worker, which may lead to construction quality inconsistencies, increasing the risk of construction. Therefore, when the main rib 1, the lateral rib 11, and the fixing mechanism 7 are of the same specification, the lateral rib 11 is fixed to the main rib 1 by the stopper frame 6 and the fixing mechanism 7, and the consistency and reliability of the connection of the lateral rib 11 can be increased.

When the tail end of the uppermost main rib 1 is positioned on a floor layer, two main ribs 1 and two fixing ribs 3 are required to be connected by adopting a connecting cylinder 4 and a limiting shell 43, the lengths of the main ribs 1 and the fixing ribs 3 are increased, the connection between the adjacent main ribs 1 and the connection between the adjacent fixing ribs 3 are realized, and at the moment, the transverse ribs 11 can be connected at the connection positions of the two adjacent main ribs 1. When the transverse rib 11 is connected to the joint of two adjacent main ribs 1, taking the main rib 1 as an example, the limit frame 6 of the main rib 1 below is firstly installed, then after the main rib 1 is fixed by the fixing screw 611, one main rib 1 is connected to the upper side of the main rib 1 by the connecting cylinder 4 and the connecting mechanism 5, at this time, the fixing sleeve 61 matched with the limit shell 43 needs to be replaced, and after the fixing sleeve 61 is sleeved on the outer side wall of the limit shell 43, the fixing sleeve 61 is fixed by the fixing screw 611. When the fixing sleeve 61 enables the limiting shell 43 to be installed at the joint of the two main ribs 1, the fixing sleeve 61 can further increase the stability of the two spliced limiting shells 43 and prevent the two limiting shells 43 from being separated.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
