Disclosure of Invention
The utility model provides an assembled bracket segment aiming at the problem of slow speed of traditional full framing erection, when the full framing is erected, a plurality of segments which are processed in advance can be combined according to the requirement, thereby realizing the rapid erection of the bracket; in addition, the support joint is in pin joint and screw joint by welding, so that the mounting and the dismounting are convenient, the stress performance of the support is improved, the reuse rate of materials is improved, and the construction cost is reduced.
The technical scheme of the utility model as follows:
an assembled scaffold segment, comprising: the device comprises 4 upright columns arranged according to 4 vertexes of a rectangle, and adjacent upright columns are connected through a plurality of cross rods and diagonal braces; a rectangular top plate is welded at the top of each upright post, and a positioning column protruding upwards is arranged in the middle of each top plate; the bottom of each upright post is welded with a rectangular bottom plate, and a positioning hole with the diameter equal to that of the positioning column on the top plate is arranged in the middle of the bottom plate; and bolt holes are respectively arranged at the upper corresponding 4 corners of the top plate and the bottom plate.
The utility model discloses predetermine reference column and locating hole in montant top and bottom, the connection otic placode is established to the montant side. When the support is erected, the plurality of sections can be butted up and down through the positioning columns and the positioning holes according to needs and are connected and fixed through bolts, or the plurality of supports are transversely connected through cross rods and inclined support rods through ear plates on the side surfaces of the vertical rods, so that the support can be erected quickly; the bracket sections adopt section steel as basic components, adopt an assembly structure, only need to be connected by pin shafts and bolts, have no on-site welding operation, can ensure the stress performance of the bracket, avoid damaging each component member of the bracket, improve the material reuse rate and save the cost.

Detailed Description
As shown in fig. 1, 2, 3 and 4, the utility model comprises 4 upright posts 1 arranged according to 4 vertexes of a rectangle, and adjacent upright posts 1 are connected through a plurality of cross bars 2 and inclined stay bars 3; a rectangular top plate 4 is welded at the top of each upright post 1, and a positioning column 5 protruding upwards is arranged in the middle of the top plate; the bottom of each upright post is welded with a rectangular bottom plate 6, and a positioning hole 7 with the same diameter as the positioning column on the top plate is arranged in the middle of the bottom plate; and bolt holes 8 are respectively arranged at the upper corresponding 4 corners of the top plate and the bottom plate.
The utility model can adopt an assembly structure, and a pair of ear plates 9 are respectively welded on the upper edge of each upright post 1 at regular intervals along the longitudinal direction and on the front, back, left and right sides 4 sides; two ends of each cross rod 2 are connected with ear plates 9 on the opposite sides of the two upright posts through pin shafts; the two ends of each inclined stay bar 3 are respectively connected with the lug plates 9 on the upright posts 1 and the middle of the cross bar 2 through pin shafts.
As a specific implementation mode, the upright posts 1 and the cross bars 2 are made of double-spliced channel steel, the notches of the double-spliced channel steel are opposite, and a certain distance is reserved between two channel steel webs and the two channel steel webs are welded and connected through a plurality of connecting blocks 10; two ends of the cross rod 2 are respectively provided with a connector 11, one end of each connector 11 is welded between two channel steels of the cross rod, and the other end of each connector 11 is connected with a pair of lug plates on the stand column through a pin shaft; a pin hole penetrating through the cross rod is formed between two channel steel webs in the middle of the cross rod, the inclined support rod 3 is a square tube, one end of the inclined support rod is connected with an ear plate on the stand column through a pin shaft, and the other end of the inclined support rod is inserted between the two channel steels of the cross rod in the middle of the cross rod and is connected with the cross rod through a pin shaft.
The utility model discloses during the concrete implementation, stand, horizontal pole, bracing are accomplished at the processing field preparation in advance, weld the otic placode on the stand in advance, predetermine the pinhole on the otic placode, and the pinhole also sets up in advance at horizontal pole both ends and centre and bracing piece both ends.
