Description
Technical field
This utility model relates to measuring on bridge dot structure technical field, measures control point in particular to a kind of wall-attachment.
Background technology
Cable-stayed bridge main-beam is owing to being limited by the intervisibility between the influence of topography, installation accuracy and girder measuring control point and ground control point, often survey when setting main beam linear and lack enough measurement control point or checkpoint, thus add task difficulty and operating cost, cause the waste of man power and material, installation accuracy does not reaches requirement yet, have impact on site operation progress.
The prior art point of observation that generally broad view, place are higher near bridge is installed total powerstation and is observed, such as mountain top or the area of hill-side broad view.But total powerstation is set up on mountain top, one total powerstation can only be in the different same sections of time period control, end bay girder, or two total powerstations are in the same sections of control of same time period, end bay girder, and end bay control point can only control end bay, in in control point can only control across, have a strong impact on scene construction speed.
Summary of the invention
The purpose of this utility model seeks to solve the deficiency of above-mentioned background technology, it is provided that a kind of wall-attachment measures control point.
The technical solution of the utility model is: a kind of wall-attachment measures control point, it is characterised in that: include measuring instrument anchor point and survey crew anchor point；Described measuring instrument anchor point includes the fixing bar being fixed on Sarasota sidewall and the gripper shoe of its upper surface holding level being arranged on fixing bar；Described survey crew anchor point includes the operating platform being fixed on Sarasota sidewall；Described operating platform is positioned at the underface of fixing bar and gripper shoe, and between operating platform and gripper shoe, spacing distance is 1～1.5m.
Further also include the first pre-embedded steel slab being embedded in Sarasota sidewall；The end of described fixing bar is fixed on the first pre-embedded steel slab by bolt arrangement.
Further also including the diagonal brace that lower end is fixed on Sarasota sidewall, diagonal brace upper end is fixing forms stable three-legged structure on the supporting plate with gripper shoe.
Further also include the second pre-embedded steel slab being embedded in Sarasota sidewall；The end of described operating platform is fixed on the second pre-embedded steel slab by bolt arrangement.
The end, one end of the most described operating platform Sarasota dorsad is provided with guardrail.
This utility model simple in construction, by installing fixing bar and gripper shoe support measuring instrument equipment at Sarasota sidewall, the operating platform of Sarasota sidewall is as the standpoint of operator, on Sarasota, this is to measure point to solve unsighted problem, reduce the difficulty measuring operation, improve measurement efficiency, also save substantial amounts of man power and material, there is great promotional value.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model；
Fig. 2: front view of the present utility model；
Wherein: 1 operating platform；2 guardrails；3 first pre-embedded steel slabs；4 diagonal braces；5 fix bar；6 gripper shoes；7 second pre-embedded steel slabs.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1～2, a kind of wall-attachment measurement control point, including measuring instrument anchor point and survey crew anchor point, measuring instrument anchor point is used for installing measuring instrument, and survey crew anchor point is for the standpoint as survey crew.Wherein, measuring instrument anchor point includes the gripper shoe 6 of fixing bar 5 and its upper surface holding level being arranged on fixing bar 5 being fixed on Sarasota sidewall, the present embodiment pre-buried first pre-embedded steel slab 3 on Sarasota sidewall in advance, by the way of bolt or welding, the end of fixing bar 5 is fixed on the first pre-embedded steel slab 3 again, fixes and between bar 5 and Sarasota sidewall, be additionally provided with diagonal brace 4.The lower end of diagonal brace 4 is fixed on Sarasota sidewall, and its upper end is fixed on the lower surface of fixing bar 5, forms stable triangular support configurations with fixing bar 5.Junction point between diagonal brace 4 and fixing bar 5 is positioned at the lower section of gripper shoe 6.Placing measuring instrument in gripper shoe 6, therefore, the upper surface of the gripper shoe 6 of the present embodiment keeps level.
Survey crew anchor point includes the operating platform 1 being fixed on Sarasota sidewall, operating platform 1 is positioned at fixing bar 5 and the underface of gripper shoe 6, operating platform 1 is for the standpoint as survey crew, for flat board or truss structure, between operating platform 1 and gripper shoe 6, spacing distance is 1～1.5m, it is simple to operator stand measurement.
Being embedded with the second pre-embedded steel slab 7 on Sarasota sidewall, the second pre-embedded steel slab 7 is positioned at the lower section of the first built-in fitting 3, and operating platform 1 is fixed on the second built-in fitting 7 by bolt or welding manner.The end, one end of operating platform 1 Sarasota dorsad is provided with guardrail 2.Guardrail 2 is vertically fixed on the upper surface of operating platform 1.
During use, by adapter, measuring instrument is arranged in gripper shoe 6, on operating platform 1 on survey crew, measures measuring and calculating by the measuring instrument in gripper shoe 6.
During measurement: 1, according to GPS control point or JM control point coordinate, utilize total powerstation to do connecting traverse or back traverse calculates girder wall-attachment and measures the coordinate at control point；
The Coordinate Conversion that 2, wall-attachment is measured control point becomes with bridge longitudinally as X-axis, is laterally the construction coordinate system of Y-axis, controls the plan-position of girder；
3, measuring installation total powerstation on control point at a wall-attachment and make survey station point, on another wall-attachment measurement control point, installation pedestal is as backsight point, and on ground, a control point is as checkpoint, sets up coordinate system, coordinates centering prism directly can carry out field lofting；
4, two wall-attachments are measured control point and are all located at the top of girder, do not affected by sight line during measurement, and the distance between 2 can control longer than the length of on-the-spot girder, thus can reach, with the measuring method of " long limit control minor face ", to decrease the measurement error that girder plane is first.
By this utility model, the elevation face measuring girder is turned to above girder by ground, it is possible to make the measurement work of girder not affected by sight line, improve work efficiency.And checked by identical control point when measuring girder, it is to avoid error of centralization when sighting mark error during Instrument observation and different control point observation, improve the installation accuracy of cable-stayed bridge main-beam, also ensure that site operation progress.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
