1) this structure is arranged because satisfying steel column and concrete column lateral alignment, makes the total layout be subjected to the impact of technology arrangement;
2) the steel column post apart from does not wait and post distance less than normal, material usage is large;
3) the steel work specification is many, the number of components is many, and processing is complicated, installation period is long.
The another kind of valve Room is made of the knee wall of all steel rod structure, and reinforced concrete wall of increase separates the valve Room and change of current variation as fire wall outside steel column.The weak point of this structure:
1) steel column of change of current change side is arranged and is easily conflicted difficult coordination with the sleeve pipe of converter transformer valve side;
2) cost of this structure is high, and construction is trouble.
The utility model content
The purpose of this utility model is for overcoming above deficiency, provide a kind of for the high end valve of the current conversion station Room wait post apart from combination construction, this structural manufacturing process flexible arrangement reduces the difficulty of structure design, reduces the consumption of steel, thereby reduces production costs.
The purpose of this utility model can reach by taking following technical scheme:
A kind ofly wait post apart from combination construction for the high end valve of the current conversion station Room, its design feature is: the overall structure in the high end valve of the current conversion station Room adopts Steel-concrete Composite, be concrete frame structure at converter power transformer one side elevation, its excess-three facade and end face adopt steel work; Do not require that in described steel work steel column aligns with the concrete column of converter power transformer side, described steel column adopts equidistant placement.
In engineering design, can determine flexibly the post distance according to the distribution of equipment load.
The purpose of this utility model can also reach by taking following technical scheme:
Further, described Steel-concrete Composite comprises that the support body of wall, the steel roof truss that are made of steel column reach the valve Room body of wall by reinforced concrete structure, described steel roof truss is made of chord member, horizontal support and support bar, the valve Room body of wall of described reinforced concrete structure is made of reinforced concrete post, rc-frame-beam and masonry filler wall, described reinforced concrete post is T-shaped, the valve Room body of wall of described reinforced concrete structure is arranged on the one side in the valve Room, and the support body of wall that described steel column consists of is arranged on its excess-three face in the valve Room; According to the distribution of equipment load, described steel column equidistant placement is supporting on the body of wall, and every steel column links to each other with an end of chord member, and the other end of chord member links to each other with rc-frame-beam.
The beneficial effects of the utility model:
The utility model does not require that steel column aligns with RC T shape post, has reduced the difficulty of structure design owing to adopting Steel-concrete Composite.Determine flexibly the steel column distance according to the equipment load, thereby enlarged the steel column spacing, reduced the consumption of steel, also reduced rod member quantity and the specification kind of structure, reduced the cost in the valve Room.Make steel roof truss and steel column stressed evenly by the steel column equidistant placement, and reduced the difficulty that processing is installed, accelerated programming.
