Abstract

The invention relates to a reinforcement binding and jointing operating room. The operating room is a cubic structure formed by welding lower, middle and upper layer section steels; the bottom of the operating room is open; steel pipes are uniformly inserted in both the lower layer section steel and the middle layer section steel of the operating room to respectively form a lower layer operating platform and a middle layer operating platform; and a safety protective net is fixed on the outer periphery of the operating room. The invention also relates to a reinforcement binding and jointing method which comprises the following steps of: firstly, independently making the operating room; using an inner die of which a pier body is completed as a support and assembling an inner die of which a pier body is not poured; then temporarily fixing the operating room and the inner die; and assembling a detachable operating platform to carry out reinforcement construction, assembling an outer die after checking that the construction is qualified, and finally carrying out concreting. The reinforcement binding and jointing operating room and the reinforcement binding and jointing method are simple and convenient to operate; the construction safety is improved; and the reinforcement binding and jointing operating room and the reinforcement binding and jointing method can also be applied to the reinforcement binding and jointing construction of other inclined and curved structures and the like.

Background technology
In existing bridge construction, for the colligation of bridge pier shaft reinforcing bar, what routine adopted is the auxiliary construction method setting up scaffolding platform, need set up the scaffolding platform of corresponding height, but connect height for the colligation of large hollow pier reinforcing bar during construction, owing to being subject to the thickness of hollow pier wall and highly affecting, instability factor becomes many, makes reinforcing bar binding connect high construction and can become relative complex, difficulty, if constructed according to a conventional method, both cannot ensure construction safety, and can construction speed be delayed again.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of reinforcement construction process of hollow pier shaft can be made to become safe, convenient and efficiently reinforcing bar binding connect high operating room and reinforcing bar binding connects high method.
In order to solve the problems of the technologies described above, the invention provides a kind of reinforcing bar binding and connect high operating room, described operating room is the cube structure be welded by lower floor, middle level and upper strata three stratotype steel, the bottom opening of described operating room, lower floor's shaped steel and the middle level shaped steel of described operating room are all evenly equipped with steel pipe, and forming lower floor and middle level operating platform respectively, the periphery of described operating room is fixed with safety guard net.
Further, the Internal periphery size of described operating room is identical with the outer profile size of pier shaft to be built.
Further, described operating room is temporarily fixed on the internal mold of pier shaft to be built.
Further, described steel pipe is detachable steel tube, and described detachable steel tube forms the detachable operating platform of the detachable operating platform of lower floor and middle level respectively.
The present invention also provides a kind of reinforcing bar binding to connect high method,
Step one, smooth place is produced reinforcing bar binding and connects high operating room;
Step 2, utilizes the internal mold of having built hollow pier shaft to support, assembled go out the internal mold of pier shaft to be built;
Step 3, utilizes the internal mold of pier shaft to be built to support, and the reinforcing bar binding made is connect high operating room entirety and withholds on pier shaft to be built, and fix with the internal mold temporary weld of pier shaft to be built;
Step 4, connects in high operating room at reinforcing bar binding and wears detachable steel tube, assembled go out detachable operating platform;
Step 5, constructor carries out colligation to the reinforcing bar of pier shaft to be cast and connects height, after passed examination, reinforcing bar binding operating room entirety is hung pier shaft;
Step 6, installs the external mold of pier shaft to be cast, pours into a mould pier shaft concrete after passed examination.
The present invention is stressed clearly, structure is simple, easily manufactured, with low cost, constructing operation is easy, improves working security, and the present invention is through suitably improving, and the reinforcing bar binding that also can be applicable to the structure such as other inclination, curve connects high construction.
Accompanying drawing explanation
