Description

A kind of measurement control method of building operations horizontal member size

Technical field

The present invention relates to a kind of measurement control method of building operations horizontal member size, particularly a kind of accurate control that utilizes accurate measuring apparatus such as Geoplane and Sopwith staff to realize by the control line that sealing is set building unit is constructed.

Background technology

The building operations horizontal member mainly is meant the beam slab in the concrete structure, and its dimension survey control method is mainly in the control in structure construction stage.In the structure construction stage, after the horizontal member formwork erection is finished, on the wall column reinforcing bar of horizontal shuttering two ends suitable for reading, copy the high 0.5m control line of mark, draw little white line to fuse, come the planeness and the absolute altitude of controlling level template by the distance of measuring between control line and the horizontal member template, also utilize the 0.5m control line to control the concreting absolute altitude during horizontal member concreting; Lack measurement control measure to room periphery squareness.

The measurement control method of above-mentioned traditional building operations horizontal member since be subjected to cautious very little; lack control method to squareness, standard width of a room in an old-style house depth; cause horizontal member planeness, the error of perpendicularity of constructing big; can not finely satisfy the requirement of concrete structure engineering construction inspection rules; for guaranteeing the uniformity of size, pick cutter afterwards and repair, influence thickness of protection tier; stress form has brought very big workmanship hidden danger to engineering.

Summary of the invention

The measurement control method that the purpose of this invention is to provide a kind of building operations horizontal member size, the objective of the invention is in order to overcome the shortcoming and defect part in the existing building construction member size Control method, by by advanced detecting instruments such as Geoplanes, control line is measured in utilization comprehensively, from thin control, improve the construction precision of building operations scantling, improve engineering construction quality.

For achieving the above object, the present invention adopts following technical scheme:

A kind of measurement control method of building operations horizontal member size, construction sequence is as follows:

Step 1 installs the soffit formwork of the horizontal member of intend adjusting, and its bottom supporting has the holder of U type;

Step 2, the measurement control line of lower floor's horizontal member that will be through checking draws the upper surface of surveying to the soffit formwork of the horizontal member of intending adjusting from the unwrapping wire mouth by laser transit, emit the main control line, then according to the distance of each horizontal member sideline and main control line on the drawing, at the soffit formwork template position line suitable for reading of emitting suitable for reading, according to template position line suitable for reading, measure the limit mould, hang mould, beam size suitable for reading and building periphery squareness;

Step 3 is inserted into Geoplane on lower floor's horizontal member of the horizontal member of intending adjustment;

Step 4, the Geoplane self leveling is opened the switch in the scanner, presses " H " button, discharges horizontal datum;

Step 5, in same measured zone, choose four angle points and intersection of diagonal thereof as measuring point apart from its sideline 30cm～40cm place, lay Sopwith staff at point position, read on the Sopwith staff and the horizontal datum value corresponding, be the vertical distance between horizontal member soffit formwork soffit and the horizontal datum;

Step 6 as reference point, is calculated all the other points and reference point deviates with the maximum value of above-mentioned numerical value;

When step 7, deviate≤3mm, need not to adjust the soffit formwork of intending the horizontal member adjusted, deviate〉3mm, finely tune back repeating step five according to deviate to the soffit formwork of the horizontal member intending adjusting, until all the other point and reference point deviation of reading value≤3mm.

The horizontal member of the described plan adjustment of step 1 is concrete slab or concrete beam.

The described same measured zone measuring point of step 5 also comprises the mid point of same sideline two angle point lines.

The U type holder of the soffit formwork of the horizontal member that the adjacent support plan of the described angle point of step 5 is adjusted.

Compared with prior art the present invention has following characteristics and beneficial effect:

(1) utilize accurate measuring apparatus such as Geoplane and Sopwith staff to realize the accurate control that building unit is constructed by the control line that sealing is set.

(2) by size according to measured zone, determine the quantity of measuring point, increase the precision of measuring.

(3) by at the template template position line suitable for reading that is provided with suitable for reading, guaranteed the accurate positioning of concrete component to be built, avoid effectively to control horizontal concrete component in the traditional approach drawback of its size, guaranteed squareness, the standard width of a room in an old-style house depth size in room.
