Description
Technical field
The present invention relates to a kind of measuring method of scaffold upright rod verticality, relate in particular to a kind of measuring method of high formwork support system vertical rod verticality.
Background technology
Vertical rod is the compression-member that transmits construction loads in the framing scaffold; During installation if any excessive initial eccentricity apart from or initial bending; Stress to vertical rod is totally unfavorable, the framing scaffold load-bearing capacity is reduced even causes caving in because of unstability, and the bitter lesson of a lot of this respects is arranged both at home and abroad.
In all kinds of cave-in accidents that China takes place, falsework caves in and occupies larger specific gravity, and tall and big hall building (room) cover mold board mount is because the pipe personnel that execute that build on the scope of operation are more, and when caving in, the number of casualties tends to surpass 20 people.Get into 2010, China recurs new airport, Kunming and is building 3 framing scaffold accidents such as access bridge collapse accident, causes the serious consequence that 23 people are dead, 43 people are injured altogether.According to statistics, 49 of building safety accidents took place in the whole nation altogether to May in 2010 1, and wherein the framing scaffold cave-in accident has 11, and death toll accounts for 25.60% of total death toll.Firmly build portion summed up 2010 and Eleventh Five-Year Plan since the building safety production work time point out that in accident total amount and total toll decline, the accident total amount is still bigger.627 of house municipal works production safety accidents, dead 772 people were taken place in 2010 altogether; Accident plays 57 of number minimizings compared with the same period of last year; Death toll reduces by 30 people; Above accident plays number and death toll rises 38.10% and 37.76% on year-on-year basis respectively, the reason that this wherein just has the falsework cave-in accident constantly to take place but production safety reaches more greatly.When all kinds of construction brackets in carrying and using cave-in accident take place, all can cause quite serious consequence mostly.The total collapse accident that particularly tall and big concrete building (room) lid and bridge falsework take place in building often all can cause heavy casualties, enormous economic loss and bad social influence.Cause the wound that is difficult to make up not only can for wrecked personnel family, also can seriously jeopardize the survival and development of enterprise, and bring huge pressure can for engineering safety at different levels supervision department.Fastener type framing scaffold vertical rod out of plumb in setting up process makes vertical rod produce additional bending moment; Directly influence the stable bearing capacity of falsework; There is the distortion situation of crooked vertical rod in certain to have the scholar to pass through site test mensuration; Moderate finite deformation just takes place in discovery under stressed very little situation, greatly reduced the stable bearing capacity of framing scaffold.
Vertical rod is most important a kind of rod member in the fastener type steel pipe scaffold, its installation the safety and the performance of function of perpendicularity deviation value size direct relation framing scaffold, therefore, carry out the measurement of vertical rod verticality, the strict vertical rod verticality of controlling.The workman confirms the verticality of vertical rod usually through observation in actual engineering, and observation is unfavorable for the control of high-supported formwork system security owing to subjectivity, randomness are forced to such an extent that error is bigger.Under the lower situation of scaffold building height; The overweight plumb line of normal open measures the vertical rod verticality, but for the high-supported formwork system, because support body is generally higher; Tend to above 8 meters; Utilize the weight line to measure the vertical rod verticality and cause winding easily, and support body bottom shelter is more, be difficult to realize accurately measuring.There is unit in charge of construction to adopt the verticality of instrument measurement scaffold upright rods such as guiding ruler; Guiding ruler can be surveyed length and be generally 2 meters, therefore, surveys the scaffold upright rod verticality with guiding ruler; Need segmentation to carry out; Though certain feasibility is arranged, can not reflect the deviation of whole vertical rod verticality fully, it is bigger influenced by site environment.Feng Yong etc. in order to survey the verticality of support body vertical rod, adopt transit in " based on the falsework safety research of field measurement ", the vertical rod of actual measurement falsework is in the deflection of support body both direction.In the high-supported formwork system,, there are many defectives, are difficult to realize, and need repeatedly to move instrument, very inconvenience for adopting transit to survey the vertical rod verticality because less and the blocking of enclosing etc. on every side of spacing set up in vertical rod.
Summary of the invention
Defective or deficiency to above-mentioned prior art existence; The objective of the invention is to; Provide a kind of convenience, accurately, receive construction environment to influence the less measuring method that is used for high-supported formwork system vertical rod verticality; This method has adopted a kind of high-supported formwork system vertical rod squareness measurement instrument, greatly facilitates the measurement of vertical rod verticality.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of measuring method of high-supported formwork system vertical rod verticality; It is characterized in that; This method adopts the survey instrument that is combined by measuring junction and reading end, and said measuring junction is provided with the horizontal telescopic rod and vertical telescopic rod that has scale, is connected with rule on this horizontal telescopic rod and the vertical telescopic rod; This rule one end is provided with Level plate, on this Level plate RF transmitter is installed; Also be provided with the horizontal telescopic rod and vertical telescopic rod that have scale on the said reading end, this horizontal telescopic rod is provided with rule with vertical telescopic rod, specifically measures according to the following steps.
Because the rule on the measuring junction has Level plate, can make RF transmitter maintenance level, carry out the vertical transmission that vertical rod is squinted by means of its infrared ray that sends, can reflect the deviant of vertical rod upper end really with respect to its lower end.
Method of the present invention has solved the routine measurement method and has been difficult to the problem that realizes in the high-supported formwork system construction environment, has convenient, fastly, accurate, receives construction environment to influence advantages such as less.
