A kind ofly wait post apart from combination construction for the high end valve of the current conversion station Room
Technical field
The utility model relates to the combination construction in the high end valve of a kind of current conversion station Room, be specifically related to a kind of for the high end valve of the current conversion station Room wait post apart from combination construction, be applicable to ± the 800kV current conversion station.Belong to the DC transmission engineering technical field.
Background technology
At present ± 800kV extra-high voltage direct-current engineering is present whole world highest voltage level, to become the zone be most important part for the valve Room and the change of current in ± 800kV current conversion station place, therefore the structure design in the valve Room is particularly important, the height in the valve Room is 30m approximately, span is 32m approximately, length is 82m approximately, existing valve Room structure design has two kinds, the support body of wall that a kind of valve Room is made of steel column, the valve Room body of wall that steel roof truss reaches by reinforced concrete structure consists of, as shown in Figure 1, the valve Room body of wall of reinforced concrete structure is that RC T shape post distance is the concrete frame structure of 10~11m, and this post is determined apart from becoming layout by the technique specialty according to the change of current, generally can not be adjusted; And the post distance of steel column and position can cooperate definite by structure discipline and technique specialty, consider suspension equipment and arrange the requirement of making an inspection tour the aisle, the steel column post is apart from generally being not more than 9m, in the existing arrangement, steel column aligns with concrete column, and in the middle of concrete column, set up Pin roof truss and a steel column, steel is that 5m to 6.8m does not wait apart from the post distance.This structure has the following disadvantages:
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.

The specific embodiment
Specific embodiment:
Following structure accompanying drawing is further described the utility model.
As shown in Figure 2, the post such as grade that is used for the high end valve of the current conversion station Room that the present embodiment relates to is apart from combination construction, the overall structure in the high end valve of its current conversion station Room adopts Steel-concrete Composite, is concrete frame structure at converter power transformer one side elevation, and its excess-three facade and end face adopt steel work; Do not require that in described steel work steel column 1 aligns with the concrete column 4-1 of converter power transformer side, described steel column 1 adopts equidistant placement.
In the present embodiment:
Described Steel-concrete Composite comprises the support body of wall 2 that is made of steel column 1, the valve Room body of wall 4 that steel roof truss 3 reaches by reinforced concrete structure, described steel roof truss 3 is made of chord member 3-1, horizontal support 3-2 and support bar 3-3, the valve Room body of wall 4 of described reinforced concrete structure is made of reinforced concrete post 4-1, rc-frame-beam 4-2 and masonry filler wall, described reinforced concrete post 4-1 is T-shaped, the valve Room body of wall 4 of described reinforced concrete structure is arranged on the one side in the valve Room, and the support body of wall 2 that described steel column 1 consists of is arranged on its excess-three face in the valve Room; According to the distribution of equipment load, described steel column 1 equidistantly is arranged on and supports on the body of wall 2, and every steel column 1 links to each other with the end of chord member 3-1, and the other end of chord member 3-1 links to each other with rc-frame-beam 4-2.At the chord member 3-1 of steel roof truss 3 converter valve suspention beam 5 and miscellaneous equipment suspention beam 6 are installed.
