Abstract
The invention discloses a kind of power plant main power house armored concrete coal hopper construction technology, the problem of improving complicated existing coal hopper construction, waste of manpower.The present invention comprises the following steps：（1）Pour four side crossbeams of funnel, and the pre-embedded steel slab in crossbeam；（2）A steel platform is lifted with pull rod, and by the top of pull rod and Interal fixation；（3）The installation form supporting rack in steel platform；（4）From bell mouth lower to upper part successively primary concreting concrete, pour to surrounding crossbeam lower part, and combined tightly with crossbeam lower part；（5）In funnel storey setting support shuttering, and carry out funnel floor concreting；（6）Form removal supporting rack, support shuttering, steel platform and pull rod.The present invention is supported using steel platform, and whole reinforced concrete soil hopper weight and construction loads are carried by steel platform, and funnel weight and construction loads are not carried in each floor plates under funnel so that and it is easy for construction, it is easy to operate, reduce manpower.
Description
Technical field
The present invention relates to a kind of power plant main power house armored concrete coal hopper construction technology.
Background technology
Armored concrete coal hopper on power plant main power house frame structure frame, be arranged on main building frame structure frame top compared with
Eminence, commonly reaches more than absolute altitude 20m, and since armored concrete coal hopper weight is too big, each floor cannot be held under it during construction
Armored concrete coal hopper weight and construction loads, traditional formwork construction mode are carried on a shoulder pole, is successively to set up supporting rack for one layer from ground,
Each floor below reinforced steel concrete coal hopper, so as to be put down at armored concrete coal hopper lower floor as support for shuttering
Platform, carries out formwork construction.This tradition formwork construction mode is complicated, waste of manpower.
The content of the invention
In order to improve the above problem, it is an object of the invention to provide a kind of power plant main power house armored concrete coal hopper to apply
Work technique.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of power plant main power house armored concrete coal hopper construction technology, comprises the following steps：
（1）Pour four side crossbeams of funnel, and the pre-embedded steel slab in crossbeam；
（2）A steel platform is lifted with pull rod, and by the top of pull rod and Interal fixation；
（3）The installation form supporting rack in steel platform, is used to support funnel template；
（4）From bell mouth lower to upper part successively primary concreting concrete, pour to surrounding crossbeam lower part, and and crossbeam
Lower part combines tight；
（5）In funnel storey setting support shuttering, and carry out funnel floor concreting；
（6）Form removal supporting rack, support shuttering, steel platform and pull rod.
Further, pre-buried two groups of steel plates are distinguished in the crossbeam both sides, and pull rod is four, is carried out respectively with one block of steel plate
It is fixed.
Yet further, the steel platform is square structure, and four pull rods are connected to four angles of steel platform.
In addition, the formwork-support is the scaffold set up by steel pipe.
The present invention is poured using three construction sections, and the first construction section is first constructed the surrounding crossbeam of funnel, and second constructs
Section construction funnel, the top floor plate of the 3rd construction section construction funnel；Such sequence of construction makes plus pull rod, steel platform etc.
Obtain whole reinforced concrete soil hopper weight and construction loads is carried by steel platform, funnel weight is not carried in each floor plates under funnel
Amount and construction loads；So that construction is more smoothly quick, while also greatly reduce manpower.
Embodiment
With reference to embodiment, the invention will be further described, and embodiments of the present invention include but not limited to following reality
Apply example.
Embodiment
A kind of power plant main power house armored concrete coal hopper construction technology, comprises the following steps：
（1）Pour four side crossbeams of funnel, and the pre-embedded steel slab in crossbeam；
（2）A steel platform is lifted with pull rod, and by the top of pull rod and Interal fixation；
（3）The installation form supporting rack in steel platform, is used to support funnel template；
（4）From bell mouth lower to upper part successively primary concreting concrete, pour to surrounding crossbeam lower part, and and crossbeam
Lower part combines tight；
（5）In funnel storey setting support shuttering, and carry out funnel floor concreting；
（6）Form removal supporting rack, support shuttering, steel platform and pull rod.
The present invention is poured by three construction sections, and supporting rack is successively set up so as to avoid one layer from ground, is reinforced
Each floor below reinforced concrete soil hopper so that construction process becomes simple, and it is also very convenient to construct, and improves construction
Efficiency.
Specifically, pre-buried two groups of steel plates are distinguished in the crossbeam both sides, and pull rod is four, is consolidated respectively with one block of steel plate
It is fixed.By four groups of steel plates and four pull rods, can fix steel platform is more firm, can also carry more construction lotuses
Carry, ensure that the safety of work progress.
In order to ensure the stability of steel platform, the steel platform is square structure, and four pull rods are connected to
Four angles of steel platform.By being arranged on four angles of steel platform, center section can be reserved and be used to funnel template be installed, it is convenient
Operation, and it is located at four angles, the construction loads that uniformly can be born steel platform is transferred to the steel plate in crossbeam.
For the ease of mounting and dismounting formwork-support, the formwork-support is the scaffold set up by steel pipe.In reality
When border is constructed, satisfactory formwork-support can be set up according to actual conditions, so that more convenient prop up
Support, simultaneously because set up by steel pipe, dismounting, installation are very convenient, improve construction efficiency.
What deserves to be explained is the present invention is supported using steel platform, whole reinforced concrete soil hopper weight and construction lotus
Load is carried by steel platform, and funnel weight and construction loads are not carried in each floor plates under funnel so that easy for construction, operation letter
It is single, reduce manpower.
According to above-described embodiment, the present invention can be realized well.What deserves to be explained is before based on said structure design
Put, to solve same technical problem, some made in the present invention are used without substantive change or polishing
Technical solution essence still as the present invention, therefore it should also be as within the scope of the present invention.
