Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1 to 3, an embodiment of the auxiliary installation device for the exposed embedded part in the prefabricated part comprises a longan 1, an adapter 2, a positioning pipe 3 and a positioning bolt 4, wherein the positioning pipe is fixedly connected with a cantilever bracket 5, the positioning bolt penetrates through the positioning pipe and is connected with the adapter, the adapter comprises a nut end 21 and a screw rod end 22, the nut end is in threaded connection with the positioning bolt, the nut end is also abutted against the end surface of the positioning pipe, the longan is sleeved on the screw rod end, and the adapter is rotatably arranged in a bolt sleeve 6 through the screw rod end and fixes the longan on the end of the bolt sleeve.

When the device is used, the cantilever support is fixed on a die according to the pre-buried position of the bolt sleeve, the positioning pipe is located above the pre-buried position of the bolt sleeve, a longan is fixed at the end part of the bolt sleeve through the adapter to form a whole, then the whole is placed in the reinforcement cage, then the positioning bolt extends into the positioning pipe from the upper port and extends out from the lower port, the positioning bolt is rotated through holding the bolt sleeve or the adapter by hand, and the positioning bolt is connected with the adapter together, so that the bolt sleeve is effectively hoisted; after concrete placement and jolt, can demolish positioning bolt and cantilever immediately, at first adopt two spanners, rotate the dismantlement to the nut end of positioning bolt and adapter respectively, wherein, the spanner of adapter department is not well changeed, mainly dismantles through the wrong commentaries on classics of positioning bolt, can take off positioning bolt after the separation, it can with cantilever dismantlement afterwards.

At the dismantlement in-process, because the adapter only ends the spacing power of changeing, and do not have axial spacing power, consequently can appear bolt sleeve position after dismantling and sink, only need this moment before cantilever disassembly, can reset through carrying to carrying of adapter nut end, carry and draw the back, nut end and location socle bottom butt are promptly accomplished the restoration promptly, later with cantilever demolish the cantilever can.

After the dismantlement is accomplished, registration arm, positioning bolt and cantilever can circulate and use, and adapter and longan are then not demolishd temporarily, and the adapter blocks up the bolt sleeve, and in the unable bolt sleeve that gets into of concrete, the adapter still sticiss the longan on the bolt sleeve, effectively blocks that the concrete gets into and pollutes the threaded connection portion of bolt sleeve and adapter from between bolt sleeve and the longan, and the convenient dismantlement of adapter.

In order to reduce the use cost, the positioning bolt is composed of a first threaded rod 41 and a first nut 42 screwed on the first threaded rod in a welding and fixing mode, the first threaded rod and the first nut are existing objects in a factory, customization is not needed, and when the positioning bolt is damaged, quick replacement can be achieved. The screw end is the second nut, and the screw rod end is the second threaded rod, and the adapter is formed by second nut and second threaded rod along axial arrangement and welding preparation, and second nut and second threaded rod are current article in the mill, need not the customization, and when damaging, replacement that can be quick, second nut and first nut model are unanimous to first threaded rod can directly be established soon on the second nut, and is simple convenient.

The demolding angle 11 is arranged on the periphery of the surface of the longan, so that the longan is conveniently separated from concrete, and the demolding agent can be coated on the surface of the longan, so that the demolding effect is improved.

In one embodiment, the nut end of the adapter is welded and fixed with the surface of the longan, the adapter and the longan form an integrated structure, and the structure is not scattered, easy to store and not easy to lose; when needs are dismantled the longan, can strike the longan surface earlier, carry out vibration isolation with longan and concrete, adopt the spanner to rotate the nut end afterwards, connect the longan with the adapter and take off from the bolt sleeve.

In an embodiment, the cantilever support includes a fixed base 51, a suspension beam 52 is disposed on the fixed base, and the suspension beam and the positioning tube are directly and fixedly connected together by welding, so that the cantilever support is simple in structure and convenient to manufacture.

Referring to fig. 4, in an embodiment, a guide sleeve 53 is further welded and fixed on the suspension beam, and a quick locking screw 54 is arranged on the guide sleeve.

The above embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto.
