Abstract
The utility model relates to a measurement control bench with a nuclear island inner structure, belonging to the nuclear power civil engineering construction technical field. The measurement bench has a bracket comprising a bottom bracket and at least one stage of upper bracket, wherein, the bottom bracket consists of three supporting legs and three beams for connecting the two adjacent supporting legs, the upper end of each supporting leg is fixed with a connecting flange, the upper bracket consists of three supporting rods corresponding to the bottom bracket and transoms for connecting adjacent supporting rods, the upper end and the lower end of the supporting rod are respectively fixed with the connecting flange corresponding to the bottom bracket, the measurement bench further comprises a triangular head plate which can be fixed on a top bracket. The measurement control bench can provide a stable operation board for the nuclear island inner structure civil engineering survey operation, thereby bringing great convenience to the measurement operation of the nuclear island inner structure, guaranteeing the measurement quality and basically avoiding the conflicts of the measurement operation and other constructions in the nuclear island inner structure.
Description
Technical field
The utility model relates to a kind of civil engineering of nuclear island inner structure and measures aid, and especially a kind of nuclear island inner structure is measured the control frame, belongs to nuclear power civil engineering technical field.
Background technology
In the nuclear island inner structure, the special embedded part that positioning accuracy request is high is a lot, therefore need measure comparatively accurately.But nuclear island inner structure space is narrow and small, and therefore irregular structure is measured operation and had bigger the conflict with other construction activities in the civil engineering process, and particularly the tower crane influence to the reactor core place is bigger.
The utility model content
The purpose of this utility model is: at the problem that above prior art exists, propose a kind of nuclear island inner structure that can effectively improve nuclear island inner structure measurement quality and measure the control frame.
In order to reach above purpose, nuclear island inner structure of the present utility model is measured the control frame and is contained support, described support comprises bottom bracket and one-level upper layer bracket at least, described bottom bracket is made of with three crossbeams that are connected adjacent two supporting legs three supporting legs, the upper end of every supporting leg is fixed with joint flange, described upper layer bracket is made of corresponding with bottom bracket three support columns and the crosspiece that connects the adjacent supports post, the fixing respectively joint flange corresponding with bottom bracket of the upper and lower side of described support column also comprises the triangle top board that can be fixed on the superiors' support.
This measurement control frame can be measured operation for nuclear island inner structure civil engineering provides a stable operation platform, thereby greatly facilitate the measurement operation of nuclear island inner structure, guarantee to measure quality. and can avoid measuring conflicting of other constructions in operation and the nuclear island inner structure substantially.

Embodiment
Embodiment one
The nuclear island inner structure of present embodiment is measured the control frame as shown in Figures 1 to 4, is made up of triangle upper layer bracket (highly being respectively 500mm, 1000mm, 2000mm) and a dismountable top board of the high A type bottom bracket of 500mm and B, C, three kinds of model specifications of D.Bottom bracket as shown in Figure 1, three supporting leg A1 lay respectively at the place, summit of equilateral triangle, fixing between adjacent two supporting legs by crossbeam A2 welding, the upper end of every supporting leg A1 is welded with oval-shaped joint flange A3, is drilled with bolt hole (referring to Fig. 3) near the focus of each oval joint flange.
The upper layer bracket of three kinds of height specifications as shown in Figure 2, constitute by corresponding with bottom bracket three support column B1 and the crosspiece B2 that connects the adjacent supports post, be connected by "＞" font crosspiece B2 welding between each adjacent supports post B1, the upper and lower end of each support column B1 welds the fixing oval joint flange (referring to Fig. 3) corresponding with bottom bracket respectively.
In addition, be shaped on the bolt hole corresponding near three summits of triangle top board shown in Figure 4, therefore can be fixed on as required on the superiors' support with joint flange.
When in construction, needing to measure, A type bottom bracket is installed at first, thereon with the good top board of bolt, can be carried out the measurement operation of low layer with that again; Along with the progress of engineering, in the time of need carrying out the measurement of higher level, can pull down top board, the triangle upper layer bracket of as one sees fit B, C, D type being installed respectively installs top board once more then, carries out the measurement operation of corresponding height.
Like this, the location of the higher special built-in fitting of the common built-in fitting of different layers high position and bearing accuracy, Equipment Foundations, concrete structure all can be measured accurately.Facts have proved, the nuclear island inner structure of present embodiment is measured the control frame and is had the following advantages: in measuring process, this measurement bay can be installed in nuclear island inner structure reactor core tower crane inside, promptly saved the space, can not clash again with nuclear island inner structure construction equipment, thereby measure operation for nuclear island inner structure civil engineering a stable operating platform is provided, improved the measurement efficiency of operation greatly, and guaranteed the measurement quality.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
