Abstract
The invention discloses a construction process for a reinforced concrete coal hopper of a power plant main building. The problems that construction of an existing coal hopper is complex, and manpower is wasted are solved. The construction process comprises the following steps that (1) large beams on the four sides of the top of the hopper are formed through pouring, and steel plates are pre-embedded into the large beams correspondingly; (2) a steel platform is lifted by pull rods, and the tops of the pull rods are fixed to the steel plates correspondingly; (3) a template support is installed on the steel platform; (4) concrete is poured layer by layer by one time from the lower portion of a hopper opening to the upper portion until poured to the lower portions of the surrounding large beams and combined with the lower portions of the large beams tightly; (5) a support template is arranged at the top of a hopper top floor, and concrete is poured for the hopper top floor; and (6) the template support, the support template, the steel platform and the pull rods are removed. According to the construction process, the steel platform is adopted for supporting, and the weight of the reinforced concrete coal hopper and construction loads are all borne by the steel platform and are not borne by any floor board under the hopper, so that construction is convenient, operation is easy, and usage of manpower is reduced.
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, it is arranged on main building frame structure frame top higher position, commonly reach more than absolute altitude 20m, owing to armored concrete coal hopper weight is too big, during construction, each floor can not undertake armored concrete coal hopper weight and construction loads under it, tradition formwork construction mode, it is successively set up bracing frame from one layer of ground, each floor below reinforced steel concrete coal hopper, thus at armored concrete coal hopper lower floor place as support for shuttering platform, carrying out formwork construction.This tradition formwork construction mode is complicated, waste of manpower.
Summary of the invention
In order to improve the problems referred to above, it is an object of the invention to provide a kind of power plant main power house armored concrete coal hopper construction technology.
To achieve these goals, the technical solution used in 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) build four limit crossbeams of funnel, and in crossbeam pre-embedded steel slab；
(2) a steel platform is lifted with pull bar, and by the top of pull bar and Interal fixation；
(3) installation form bracing frame on steel platform, is used for supporting funnel template；
(4) from bell mouth lower to upper part successively primary concreting concrete, build to surrounding crossbeam bottom, and be combined tightly with crossbeam bottom；
(5) at funnel storey setting support shuttering, and funnel floor concreting is carried out；
(6) form removal bracing frame, support shuttering, steel platform and pull bar.
Further, described crossbeam both sides are pre-buried two groups of steel plates respectively, and pull bar is four, is fixed with a block plate respectively.
Yet further, described steel platform is square structure, and four pull bars are connected to four angles of steel platform.
It addition, described formwork-support is the scaffold set up by steel pipe.
The present invention adopts three construction sections to build, and the first construction section is first constructed the surrounding crossbeam of funnel, the second construction section construction funnel, the top floor plate of the 3rd construction section construction funnel；Such sequence of construction adds upper connecting rod, steel platform etc. so that all reinforced concrete soil hopper weight and construction loads are by steel platform bearer, and each floor plates under funnel does not carry funnel weight and construction loads；So that construction is quick more smoothly, also greatly reduce manpower simultaneously.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
A kind of power plant main power house armored concrete coal hopper construction technology, comprises the following steps:
(1) build four limit crossbeams of funnel, and in crossbeam pre-embedded steel slab；
(2) a steel platform is lifted with pull bar, and by the top of pull bar and Interal fixation；
(3) installation form bracing frame on steel platform, is used for supporting funnel template；
(4) from bell mouth lower to upper part successively primary concreting concrete, build to surrounding crossbeam bottom, and be combined tightly with crossbeam bottom；
(5) at funnel storey setting support shuttering, and funnel floor concreting is carried out；
(6) form removal bracing frame, support shuttering, steel platform and pull bar.
The present invention is built by three construction sections, successively sets up bracing frame thus avoiding from one layer of ground, each floor below reinforced steel concrete funnel so that construction process becomes simple, and it is also very convenient to construct, and improves efficiency of construction.
Specifically, described crossbeam both sides are pre-buried two groups of steel plates respectively, and pull bar is four, is fixed with a block plate respectively.By four groups of steel plates and four pull bars, it is possible to that is fixed by steel platform is more firm, it is also possible to carry more construction loads, it is ensured that the safety of work progress.
In order to ensure the stability of steel platform, described steel platform is square structure, and four pull bars are connected to four angles of steel platform.By being arranged on four angles of steel platform, it is possible to reserve mid portion for installing funnel template, convenient operation, and it is positioned at four angles, it is possible to the uniform steel plate construction loads that steel platform bears being transferred in crossbeam.
For the ease of installation and removal formwork-support, described formwork-support is the scaffold set up by steel pipe.When practice of construction, it is possible to according to practical situation, it is possible to set up satisfactory formwork-support, thus convenient is supported, simultaneously because set up by steel pipe, dismounting, install all very convenient, improve efficiency of construction.
What deserves to be explained is, the present invention adopts steel platform to be supported, and whole reinforced concrete soil hopper weight and construction loads, by steel platform bearer, each floor plates under funnel do not carry funnel weight and construction loads so that easy construction, simple to operate, decrease manpower.
According to above-described embodiment, the present invention just can be realized well.What deserves to be explained is; under premise based on said structure design, for solving same technical problem, even if some making in the present invention are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the present invention, therefore it should also be as in protection scope of the present invention.
