Through the cooperation of nut and adjusting bolt, adjusting bolt passes trompil and the intraductal steel pipe contact of steel pole sleeve, and then further improves the stability between steel pipe and the joist.
Preferably, connecting holes for fixing the joist board are formed at two ends of each joist. The preset connecting holes are convenient to connect and fix with the scaffold board when the scaffold board is laid later.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the sleeve is arranged in the gap between the two joists, the sleeve can slide left and right in the gap to adjust the position, the limiting plates are arranged on the upper side and the lower side of the steel rod sleeve, so that horizontal supporting force is provided for the steel rod sleeve, the stability is high, the step of integrally pulling up the steel rod sleeve and the frame body through the horizontal rod is reduced, the arrangement is flexible, when the steel rod sleeve is installed with an external scaffold board, the steel rod sleeve is fixed with the two joists through the connecting holes by using the bolts, a worker can adjust the scaffold board in real time, the operation is convenient, the steel rod sleeve is provided with the holes, and the adjusting bolts are screwed into the nuts at the holes to contact with the steel pipes in the steel rod sleeve, so that the stability of the fixation of the joists and the steel pipes is improved.
Drawings
FIG. 1 is a top view of the present utility model;
FIG. 2 is a front view of the present utility model;
the steel bar support comprises a 1-joist, a 11-gap, a 12-connecting hole, a 13-hollow groove, a 2-sleeve, a 21-steel bar sleeve, a 22-limiting plate, a 23-opening, a 24-adjusting bolt, a 3-fixing plate and a 4-fixing bolt.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, a double-groove steel joist 1 includes 2 symmetrical parallel joists 1, a gap 11 is left between 2 joists 1, a sleeve pipe sleeve 2 is adjustably installed in the gap 11, a hollow groove 13 is provided at the web position of each joist 1, a plurality of fixing bolts 4 for preventing the sleeve pipe sleeve 2 from moving are provided in the hollow groove 13, and a fixing plate 3 is connected between 2 joists 1. The sleeve 2 can slide in the gap 11 to adjust the position.
Each sleeve 2 comprises a steel rod sleeve 21 for passing through a steel pipe, limiting plates 22 are sleeved on the upper side and the lower side of the steel rod sleeve 21 exposed out of the gap 11, and 2 limiting plates 22 are contacted with the joist 1. The limiting plate 22 can prevent the steel rod sleeve 21 from swinging in the gap 11, so that the steel rod sleeve 21 can always keep a vertical state, and meanwhile, horizontal supporting force is provided for the steel rod sleeve 21, and stability is improved.
