Description
Technical Field
The utility model relates to a building construction equipment field specifically is a truss structure is device slowly falls at uniform velocity.
Background
The truss is a steel structural component commonly used in building construction, and at present, after the assembly of large-scale truss structure is accomplished, the support frame is descended to the mode that adopts the extraction backing plate mostly during the uninstallation, and the mode that adopts jack and backing plate to combine together is as slowly falling the device when few structures uninstall. If a base plate extraction mode is adopted, damage risks are increased due to uneven stress of the structure in the unloading process, and the support suddenly drops due to the influence of bearing capacity when the support drops, so that certain potential safety hazards exist; and if the mode of combining the jack and the base plate is adopted, the operation is complicated, and the bearing contact surface of the top surface of the jack is too small.
SUMMERY OF THE UTILITY MODEL
The utility model provides a truss structure is device slowly falls at uniform velocity, and it is big to bear the contact surface, can place multiple support body, safe and reliable, easy operation.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a truss structure is device that slowly falls at uniform velocity, includes restraint festival and from restraint festival upper end male bearing festival, the inboard bottom of restraint festival placed the quicksand, the lower extreme of bearing festival contact with the quicksand, the lower part lateral wall of restraint festival on be provided with and unload husky mouth, unload and be provided with detachable metal stopper on the husky mouth.
Preferably, the restraining joint is formed by welding a 30mm steel plate serving as a bottom plate and a phi 500mm multiplied by 10mm steel pipe serving as a restraining wall.
Preferably, the bearing joint is a sealed welding structure, a steel plate with the thickness of 20mm is used as a bottom plate, a steel pipe with the diameter of 440mm multiplied by 10mm is used as a bearing wall, and a steel plate with the thickness of 20mm is used as a top sealing plate.
Preferably, the sand unloading openings are uniformly arranged around the circumference by 4 and are made of internal thread steel pipes with the diameter of 30mm multiplied by 5 mm.
Preferably, the metal plug is a hexagon bolt matched with the sand unloading opening.
Compared with the prior art, the beneficial effects of the utility model are that:
the bearing contact surface is large, various frame bodies can be placed, the application is wide, the size is small, the weight is light, an operator can easily move, safety and reliability are realized, and the operation is simple.

fig. 2 is a top view structural diagram of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1-2, the utility model relates to a truss structure is slow descending device at uniform velocity, including restraint festival 1 and from restraint 1 upper end male bearing festival 3, restraint 1's inboard bottom placed the quicksand 2, bearing festival 3's lower extreme and quicksand 2 contact, restraint 1's lower part lateral wall on be provided with and unload husky mouth 4, unload husky mouth 4 on be provided with detachable metal stopper 5.
As an embodiment of the utility model, the constraint joint 1 adopts a 30mm steel plate as a bottom plate and a phi 500mm multiplied by 10mm steel pipe as a constraint wall, and the two are welded together; the bearing joint 3 is a sealed welding structure and is made of a 20mm steel plate as a bottom plate, a phi 440mm multiplied by 10mm steel pipe as a bearing wall, a 20mm thick steel plate as a top sealing plate, 4 sand unloading openings 4 are uniformly arranged around the circumference and are made of phi 30mm multiplied by 5mm internal thread steel pipes; wherein, the metal plug 5 is a hexagon bolt matched with the sand unloading opening 4.
When the sand-loading and unloading device is used, the sand-loading and unloading port 4 is arranged at a position 50mm away from the bottom of the restriction joint 1, then the metal plug 5 is used for plugging the sand-loading and unloading port, the quicksand 2 is poured into the restriction joint 1 after the sand-loading and unloading device is completed, finally the bearing joint 3 is placed, the bearing joint 3 is connected with the truss frame body at the upper end, then the metal plug 5 is opened to slowly discharge the quicksand 2, and the slow descending of the bearing joint 3 can be realized.
While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
