Description
Technical field
The utility model has designed a kind of architecture storey absolute altitude detector, and this instrument uses simple, and reliable and stable, the life-span is long.
Background technology
When floor is built in traditional building shop the workman must strict detection layers with layer between height, the levelness of template, parameters such as flatness.Generally speaking, need strict requirement (table 1) construction, and guarantee the described template acceptance requirement of table 2 according to GB50209-2002 " building ground engineering construction quality acceptance specification ".Just so far, this loaded down with trivial details TT&C task mainly relies on manpower to accomplish.
Table 1 flooring and ground construction acceptance criteria
The permissible variation and the method for inspection that table 2 cast-in-place structural template is installed
The method of manual measurement is generally following: construction personnel guarantees absolute altitude through on scaffolding steel pipe, laying template; Survey crew uses the 2m guiding ruler above template then; Other each item indexs (flatness, the bed die surface absolute altitude and the gradient etc.) of plank are laid in the inspection of instruments such as wedge shape clearance gauge and spirit-leveling instrument.The adjustment template (inserting wedge through under the template) from the below is measured, adjustment more again then.Could begin next step building operation up to standard compliant acceptance specification.This method needs the workman to rely on the operation of self operating experience and standard to guarantee the accuracy of measuring.Because standard is accurate to the millimeter level so the operation of measuring the workman is required than higher, must be very careful careful in the time of detection, personnel demand is also many, complex operation, it is not very accurate obtaining the result at last yet.To sum up; The result that this measuring method is brought is:
precision whether depend on when survey crew is measured standard operation fully, error is very big in the reality, accidentalia is fairly obvious, confidence level is lower;
efficiency of measurement and precision are low; Working strength is big, and personnel demand is many.
The utility model content
The purpose of the utility model is to overcome existing the problems referred to above in manual detection flooring each item index, and a kind of architecture storey absolute altitude detection system is provided, and is easy to use, and precision is high.
For achieving the above object, the design of the utility model is:
This system is divided into two parts, hand-held set and detector main body, system can realize measuring automatically and data acquisition through the detector main body like this; The monitoring in real time thereby real time data that receives each item index that computing needing to obtain by the operator through hand-held set then is achieved, because measurement target (whole floor) area is very big, and complex circuit in the building site; Be unfavorable for dragging the line operation; So the mode through wireless networking not only can solve large-area splicing problems of measurement, simultaneously; Radio operation; The cable of the wire communication of avoiding is too much, influences the interference of other work, thereby can realize accurately apace the The real time measure to laying template each item index through above step total system.
According to above-mentioned design, the utility model has adopted following mechanism and scheme:
A kind of architecture storey absolute altitude detector; Comprise apparatus subject and hand-held set; It is characterized in that said hand-held set is connected through the spi interface with main control chip by hand-held set wireless networking module, main control chip and liquid crystal display and button connect and compose the hand-held set subscriber interface module; The structure of said detector main body is: the vertical rotating mechanism that laser range sensor is housed connects a horizontal rotary mechanism through a web joint; This lower horizontal rotating mechanism is installed on the tripod for building, and said vertical rotating mechanism side is equipped with detector subject radio networking module and detector subject user interface module.
