Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the embodiment of the utility model discloses a mould case in well pit is built in room, including plank sheathing 1, flitch 2 and steel pipe 3, five plank sheathing 1 constitute the box of the open cube structure of suitable for reading, every inside wall of box all vertical laminating has a plurality of flitches 2, flitch 2 adopts the iron nail to be connected fixedly with plank sheathing 1, a plurality of steel pipe 3 vertical cross support is in the box, and the both ends of steel pipe 3 respectively with the inside wall or the 2 butts of flitch of the box that correspond, butt department adopts 2 steel nail part nails to go into the square timber, the steel nail tail end presss from both sides tight steel pipe, the interval that is used for between a plurality of steel pipes 3 of support in the box need enter through concrete side pressure and calculate the back rational arrangement. The steel pipe 3 can be selected from a butt-bracing fastener type steel pipe. The bottom of box is seted up with the anti observation hole 4 that floats of the inner chamber intercommunication of box, and the anti 4 inner wall connections in observation hole that float have steel mesh 5. The steel wire mesh 5 is fixed with the box body through a template strip 6. The anti-floating observation hole 4 is designed by adopting a 30cm multiplied by 30cm steel wire mesh 6 and a 5cm multiplied by 20cmD template strip 6 to be fixed and sealed with the box body. The anti-floating observation hole 4 can be used as an exhaust hole to play an exhaust role, so that bubbles at the bottom of the box body are timely removed through the anti-floating observation hole 4 in the pouring and vibrating processes, the quality of a bottom concrete finished product is prevented from being poor, and the phenomena of holes, honeycombs and the like are avoided.

In this embodiment, wire net anti observation hole 4 that floats has been seted up at the top of box to the condition in the observation box is favorable to.

In this embodiment, the top of box is equipped with steel pipe cross arm 7 to through reinforcing bar pull rod 8 and bottom plate reinforcing bar or stake anchor steel bar welding.

The utility model provides a mould case in well hole is built in room takes off the off-site centralized processing when the construction, then whole hoist and mount get into the basic well hole internal fixation that has accomplished reinforcement. And (3) carrying out anti-floating reinforcement according to anti-floating calculation: firstly, the upper part of the box body is additionally provided with a steel pipe cross arm so as to be welded and connected with a bottom plate steel bar or a pile anchor steel bar through a steel bar; secondly, the upper part of the box body adopts a counter weight measure. And after the reinforcement is finished, performing concrete pouring construction. In specific implementation, the anti-floating reinforcement of the box body is reasonably arranged through calculation. The concrete should be symmetrically poured on four sides in the construction process, the concrete should be vibrated, the hole state should be observed, and the release agent is coated on the outer surface of the wood formwork 1, so that the formwork can be conveniently detached.

The utility model provides a well pit centre form case is built in room has following technological effect:

1. compared with the conventional formwork, the construction method has the advantages that the centralized processing outside the field and the integral hoisting are adopted, the construction efficiency is high, the cross interference on the site is avoided, and the labor is saved. The existing group tower is adopted for hoisting, and the mechanical cost is not increased.

2. Because centralized processing and integral hoisting effectively avoid the crossed construction of steel bar workers and woodworkers, only advance processing is needed, the pit inner formwork box is installed after the steel bar construction is finished, if the formwork is assembled on site, the time consumption is long when the formwork, the inner ribs and the outer ribs, the supports and the like are assembled after the steel bar construction is finished, and therefore the construction period can be effectively saved. Meanwhile, the bottom die is not erected in the traditional erecting mode, the side wall of the pit at the position is used as formwork lifting concrete for construction during concrete pouring, and waiting time is long, so that time can be effectively saved.

3. The active air exhaust can be realized in the concrete pouring process, the vibration effect can be observed, and the concrete pouring quality can be effectively ensured.

4. The construction is safe, and the requirements of site construction are met.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
