The pressure can be evenly distributed on the beams around the top frame 1. Meanwhile, the bottom frame 2 can be stressed uniformly. And the supporting capability of the whole frame is greatly improved by the support of the supporting beams 8 at the two sides.

In the 5 installation of mullion, anticreep board 4 receives the butt and removes backward, and buffer spring 23 receives the compression, and buffer spring 23 can play the effect of buffering, avoids taking place great rocking in the 5 use of mullion, can improve the anticreep ability of fixing bolt 15 upper nut simultaneously, and 5 in use of mullion are more firm. The outer hanging rack can replace the existing scaffold, saves the installation space and improves the installation convenience. Also make constructor have good stability when being under construction on the stores pylon, constructor and stores pylon all can not take place to rock, and the precision during construction obtains promoting, is difficult for bumping between the outside wallboard and damages in the work progress, can reduce the influence of rocking the bring in the installation. The whole bearing capacity is larger, and more construction articles can be placed. The installation before the construction and the dismantlement after the construction are all comparatively convenient, can adapt to the efficient use of modern fabricated building. In the process of keeping construction stable and fast, the outer hanging rack has the functions of protecting dust from flying and avoiding falling objects and improving the safety of constructors.

In the stores pylon use, one end stretches out the outside external stores pylon body that is used for the installation top of building, and stores pylon body act as the scaffold frame and cooperate the use. The inside that the staff produced when building outside construction can be lost into storing groove 9 is stored, and the rubbish that the work interval dropped or other impurity also can fall into the inside of storing groove 9 and place, have avoided the high altitude thing that falls in the work progress, have improved the security in the work progress. And the storing groove 9 can be freely dismantled and installed below the bottom frame 2 through the buckle 10 and the slide rail plate 34, the rubbish stored in the storing groove 9 can be collected and cleaned in a unified mode subsequently, the storing groove 9 can be dismantled and replaced after being damaged, and the cost of subsequent maintenance is low. Some cooling water can be put into in advance to the inside of storing groove 9, can put out a fire with water when the conflagration breaks out, reduces the risk that the conflagration spreads.

In the work progress, if there is dust or other building debris to produce, can be with the dustproof curtain 25 of underframe 2 tip pulling downwards, one of them dustproof curtain 25 of pulling can drive another dustproof curtain 25 and move downwards together, and then two dustproof curtains 25 can shelter from the cover with the outer end of pylon, and dustproof curtain 25 can play certain isolated effect, reduces the harm that the dust drifted away and brought the environment. Can bond through the magic subsides of outside from taking after dustproof curtain 25 expandes, can splice the dustproof curtain 25 that has elasticity in below both sides, can improve dirt-proof performance. And the dust curtain 25 can be unfolded or stored by the handle bar 33. The joint 31 at handle pole 33 top inserts the bottom of bevel gear 30, twists handle pole 33 and can drive bevel gear 30 and rotate, and then drives the drive gear 32 rotation of both sides to drive winding axle 24 and rotate, realize accomodating or expanding of dustproof curtain 25. The positioning rod 26 can position the winding shaft 24 under the pressing of the pressing spring 28, so that the dust-proof curtain 25 is prevented from being driven to rotate by the winding shaft 24 under the action of self gravity, and the dust-proof curtain 25 can be stably stopped at a certain position. And does not interfere with the normal movement of the dust curtain 25 in use.

When dangerous condition takes place, constructor can improve the chance of existence through descending rope 12 downstream, avoids leading to dangerous emergence in time because of the rescue. The escape device composed of the descending rope 12 and the pulleys is a high-rise rope escape device commonly used in the market, and the purchased escape device can be installed on the top frame 1 when the outer hanging frame is manufactured, so that the subsequent installation step is omitted. And the assembled building can be installed mullion 5 and top frame 1 and underframe 2 when prefabricated, and each part of the subsequent assembled building can drive the external hanging rack to hoist uniformly when assembled, so that the assembled building is safer and more efficient. The whole external hanger can be quickly disassembled after construction, the fixing bolt 15 and the bearing plate 7 left over in the building can be removed or used for other purposes according to actual requirements, subsequent construction is convenient to recycle, different working environments can be adapted, and construction cost is saved.
