Description of the embodiments
The present application is described in further detail below with reference to the accompanying drawings.
Examples
The embodiment of the application discloses shaped steel platform of unloading of encorbelmenting, refer to fig. 1, 2, including connecting girder 110 and the platform body 100, connect girder 110 and connect in the platform body 100 through reinforced structure. The two connecting main beams 110 are arranged at intervals, the gap length between the two connecting main beams is 2100mm, the secondary beams 111 are welded on the lower side of the overhanging part of the connecting main beam 110, the connecting main beam 110 is I-steel, and the secondary beams 111 are channel steel.
Referring to fig. 3 and 4, guardrails 112 are fixedly installed at both sides of the secondary beam 111, and the overhanging portion is reinforced by a wire rope 121. The pull ring 120 is embedded in the upper wall body, and the pull ring 120 is welded at the overhanging part of the connecting girder 110, and is pulled by the steel wire rope 121. The fixed fender bank 113 that is provided with of connection girder 110 downside, the inboard conflict of fender bank 113 is in the outer wall department of the platform body 100, mainly through welded fastening connection in connection girder 110, forms the reinforcement effect of conflict.
Referring to fig. 5 and 6, the reinforcing structure in this embodiment includes an embedded bolt 130 embedded in the platform body 100, and a pressing plate 131 fixedly connected to the embedded bolt 130 and abutting against the upper side of the connecting main beam 110, where the embedded bolt 130 is U-shaped, and its closed position is embedded in the platform body 100, and its opening position wraps the connecting main beam 110, and the embedded depth is at least 80mm. The pressing plate 131 is provided for the two ends of the embedded bolt 130 to penetrate out, and the penetrated part is in threaded connection with a double nut.
Reinforcing steel bars 132 are arranged at the bent angles of the embedded bolts 130, and reserved gaps are reserved between the reinforcing steel bars 132 and the bent angles and are positioned at the center positions of the bent angles. And a wood pad 114 is arranged on the lower side of the connecting girder 110, and the thickness of the wood pad 114 ranges from 15 mm to 25mm.
Meanwhile, wood plugs 140 are filled between the two sides of the connecting girder 110 and the embedded bolts 130, the extending length of the wood plugs 140 in the vertical direction is approximately half of the whole length of the connecting girder 110, and the filling requirement is that the wood plugs are positioned in the middle of the connecting girder 110.
The distance between the wooden plugs 140 and the embedded bolts 130 is greater than the distance between the two sides of the connecting girder 110 and the embedded bolts 130. That is, the width of the wooden plug 140 is greater than the width of the upper side of the single side of the connecting girder 110, so that the wooden plug 140 is used as a direct abutting part, thereby having better buffering and abutting effects.
The principle of the embodiment of the application is as follows: the unloading platform is lifted by a tower crane. When in hoisting, the hooks at four corners are hung firstly, and primary signals are transmitted, but only the platform can be lifted slightly, and the cable-stayed steel wire rope 121 can be formally hoisted after being loosened. The four corners hauling ropes of the lifting hook should be equal in length, so that the platform is ensured to be stable in the lifting process. After being hoisted to a preset position, the main beam of the platform is fixed with the ground anchor, then the steel wire rope 121 passes through the embedded hanging buckle, the nut and the steel wire rope 121 clip are fastened after the length of the steel wire rope 121 is adjusted to a proper position, and the tower crane lifting hook can be loosened after the steel wire rope 121 is hoisted to the preset position. One acceptance is required to be lifted once. The weight-limiting cards of the discharge platform should be hung in a distinct position near the platform.
Examples
Unlike embodiment 1, referring to fig. 7, in order to enable the wooden plug 140 to achieve the requirement of plugging both sides of the connection girder 110, however, in the present embodiment, the wooden plug 140 is provided as a separate structure due to the fact that the wooden plug 140 is not easily controlled in size, the wooden plug 140 includes plug units 141 provided at intervals, elastic members provided between the plug units 141, and locking members provided between the plug units 141 for fixing the extended state of the elastic members. It should be noted that the chock units 141 are thinner wooden blocks, and the two chock units 141 are used to abut against the embedded bolts 130 and the connecting girder 110.
Referring to fig. 8 and 9, in the present embodiment, the elastic member is a spring 142, and the locking member is inserted between gaps of the spring 142 for locking the extension length of the spring 142. A lock box 150, typically welded, is also secured to the outside of the pre-buried bolt 130. The locking member is a locking rod 152 movably disposed on the locking box 150 along a horizontal direction, wherein two sides of the locking box 150 are provided with locking long slots 151 along a direction parallel to the spring 142 for the locking rod 152 to pass through. One end of the locking lever 152 has an abutment block 153 for abutting against the outer wall of the locking box 150, and the other end thereof is screw-coupled with a locking block 154.
Referring to fig. 8, it is noted that the spring 142 in this embodiment is an unconventional spring, and the spring 142 in this embodiment has a plurality of vertically arranged locking interference sections 143 for interfering with the locking lever 152, as compared with a normal spring. Specifically, the locking interference section 143 has a section at the head and tail of each turn, for better direct interference with the locking lever 152, and the vertically disposed locking interference section 143 will provide support in a direction perpendicular to the block 140 of the wooden plug.
Referring to fig. 9 and 10, in order to avoid deflection of the spring 142 during the stretching process, a separate outer protrusion 144 is provided on the locking abutting section 143, and the separate outer protrusion is also embedded into and adapted to the locking long groove 151, so that the position of the locking abutting section 143 can be seen, and the spring 142 can be circumferentially limited. At this time, the locking rod 152 is fully inserted and can be abutted against the locking abutting section 143, and after locking, the whole body is a complete supporting body along the horizontal direction, so that the extension state of the spring 142 is fixed, the whole wood plug 140 can be repeatedly used and can be adapted to different space ranges, and meanwhile, the plug block units 141 on two sides can still realize the protection and buffering effects on the whole body.
It should be noted that, the diameter of the locking rod 152 may be selected according to the actual fillable space, and since the locking rod 152 itself will be fixed to the locking box 150 at both ends, the diameter thereof is not necessarily the same as that of the locking slot 151, and further, the spring 142 may have a certain deformation space by embedding the locking rod 152 and may also be used as a buffer space when the structure is changed.
The embodiments of the present invention are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
