Abstract
The utility model relates to a collection substrate for measuring a steel column with an ultrahigh steel structure; the concave part of a datum mark platform of the utility model coats the right angle part on the outer side of a steel component; the lower end supporter of the datum mark platform is obliquely supported on the steel component and is welded as well as fixed; a laser hole is arranged on the datum mark platform; the upper surface of the datum mark platform is welded and fixed with the supporter; an apparatus platform is fixed on the supporter; a bolt hole used for connecting the measuring apparatus is arranged on the apparatus platform; the utility model is suitable for the construction measurement of a steel structure; when a steel structure framework is mounted before a floor slab construction, no operation surfaces are measured in the air and the measuring apparatus can not be spanned. The utility model can be attached to the side wall of the steel structure to carry out measuring, thus improving the measuring precision and ensuring the safety of the personnel and the devices.
Description
Affiliated technical field
The utility model has related to building construction measurement.This measurement update pedestal has solved the difficult problem of no operatton face when superelevation layer steel construction particular surroundings is measured.
Background technology
When the structural steelwork construction survey, when steel structure frame was installed prior to floor slab construction, the scope of operation was not measured in the high-altitude, can't set up surveying instrument.
The utility model content
This patent is applied to the construction survey of the three phases A of China International Trade Centre stage engineering Steel Structure Installation.This utility model is applicable to the Construction of Steel Structure measurement, and when steel structure frame was installed prior to floor slab construction, the scope of operation was not measured in the high-altitude, can't set up surveying instrument.This utility model can be measured on the sidewall attached to steel construction, has improved measuring accuracy, has guaranteed the safety of personnel and equipment.
The technical scheme that its technical matters that solves the utility model adopts is: reference point platform recess is encased right angle, steel member outside part, diagonal brace is supported in reference point platform lower end, and also welding is fixing on the steel member, on the reference point platform, laser hole is arranged, weld fixed support above the reference point platform, fix an instrument platform in the support, a bolt hole that is used to connect surveying instrument is arranged on the instrument platform.
(1) control line:
Determine to install and measure the position of proofreading and correct pedestal for four jiaos in work layer.
(2) fixedly connected:
Reference point platform recess is encased right angle, steel member outside part, and employing is welded to connect; Diagonal brace is supported in reference point platform lower end, and also welding is fixing on the steel member.
(3) draw the survey benchmark:
Adopt laser vertical instrument that the reference mark is thrown and measure the reference point platform, must draw simultaneously at every turn and survey four reference points, form closed figures.
(4) measurement update:
Set up total powerstation when proofreading and correct the steel column verticality on a reference mark, after strict centering was just flat, another reference point of backsight was finished orientation, adopts total powerstation polar method or collimation line method, control steel column verticality.
The beneficial effects of the utility model are:
(1) measuring accuracy height:
Steel frame was prior to floor slab construction in working in the past, and the steel frame construction exceeds 4 to 5 layers on floor even higher, and the high-altitude does not have the scope of operation, can't transmit datum mark, instrument can only be set up on the low layer floor, causes the instrument elevation angle too big, and measuring accuracy is low.This utility model can steel column attached to the lifting operation layer on, both can be used as the transmission reference point, can directly measure again, improved measuring accuracy greatly.
(2) flexible efficient height:
The utility model can arbitrarily be installed, dismantle according to on-site actual situations processing along with the continuous rising of Construction of Steel Structure, establishes the station flexibly, can repeatability use, for in-site measurement provides a great convenience.
(3) stability is high:
The distortion of himself compact conformation of this member is little, adopts with steel column to be welded to connect, and advantages of higher stability and security are arranged, many unfavorable factors such as overcome the site operation collision, scrunch.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural map.
1. instrument platforms among the figure, 2. bolt hole 3. supports, 4. laser hole, 5. reference point platform 6. steel members.
Embodiment
Claims (1)
1. superelevation layer steel construction steel column measurement update pedestal, it is characterized in that: reference point platform (5) recess encases right angle, steel member (6) outside part, diagonal brace is supported in reference point platform lower end, and also welding is fixing on the steel member, laser hole (4) is arranged on reference point platform (5), welding fixed support (3) above the reference point platform (5), support on (3) and fix an instrument platform (1), a bolt hole (2) that is used to connect surveying instrument is arranged on the instrument platform (1).
