Description
Technical field
The utility model relates to Architectural Equipment technical field, particularly relates to a kind of high and big die plate deformation of timbering monitoring device.
Background technology
At present, high frame formwork at more than height 8m or span more than 18m, also or concentration line load be greater than 20kN/m, be all considered to the position that construction risk is larger, must falsework deformation monitoring be carried out on request.Propose a kind of imagination of shuttering supporting monitoring new method of simple, intuitive herein, namely implement monitoring standard module deformation of timbering with laser instrument, the advantage of the method be fast, in real time, safety and be convenient to observation.
The weak point of conventional monitoring methods
High frame formwork cave-in accident is one of serious accident type that in building engineering construction, occurrence frequency is higher, once there is template cave-in accident, not only can cause injures and deaths and the business property loss of construction operation personnel, and larger social negative effect can be produced.Therefore this construction one is to the great attention of each side that is subject to taking part in building, and high frame formwork requires to take various measures to guarantee work progress safety, and deformation of timbering monitoring is exactly a wherein important content.But traditional monitoring method exists some defects, practice of construction demand can not be met completely in theory.
Current monitoring scheme example main contents are as follows:
" 1, monitoring project: sedimentation, displacement, distortion.
2, layout of the monitoring points: position, monitoring point is arranged in girder span centre and limit vertical rod.
3, use transit and level meter to monitor, its precision should meet detection requirement.
If 4 internal light are not enough, then in supporting frame inside, lighting are installed, and are necessary for the low-voltage lighting light fixture adopting safe voltage.
5, before deposit concrete, in casting process and cast after, should assign specially monitoring personnel to support system carry out continue observation, until built.
6, when sedimentation deformation exceedes permissible value, report project manager and company's relevant technologies, safety, quality department, and sent the instruction whether stopping building and evacuate personnel by project manager.
……”
Although above-cited monitoring scheme is widely adopted in a lot of engineering, we are not difficult to find out that this monitoring method comes with some shortcomings part, and these not enough schemes that will cause are difficult to implement, or, even if do not have due effect by scheme execution yet.
1, observation procedure itself existing problems, are difficult to Timeliness coverage danger million.As long as just meaningful when being first soil matrix with spirit-leveling instrument observation sedimentation bottom, support body basis is if roof support with reinforced concrete, support body bottom can not sink, but topple over to side or fracture at vertical rod joint, so the spirit-leveling instrument being arranged on terrace position does not observe sign of caving in, just late when distortion can be found.Transit can carry out continuing observation to place's observation station after fixedly sighting, but needs the position of observation can not only have a place, this just need the observation personnel simultaneously setting up multiple stage instrument and respective numbers just can accomplish Timeliness coverage caves in sign reporting to the police.Only obviously above-mentioned requirements can not be met with observation personnel in scheme.
2, the point can observed very little.Although a lot of observation stations can be planned to the greatest extent in scheme, but effectively cannot observe these " point " in fact at all, can only monitor for a long time at the position easily seen for one or two of edge, and the observation station that major part is positioned at inside, formwork district can be blocked in the vertical rod as thick forest, be difficult to observe, unless allowed observation personnel take a risk to enter below the template in cast, this is strictly prohibited.
3, insufficient light, is difficult to observation.Formwork regional nature light is blocked, very dim, if night deposit concrete; completely invisible.Therefore also mention in scheme and illumination measures be set, however with Low voltage lamp illumination, carry out construction operation still can, for optical instrument observation then very inadequate.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of high and big die plate deformation of timbering monitoring device, enough observation stations, is convenient to Real-Time Monitoring, and alarm.
The utility model for achieving the above object, by the following technical solutions:
A kind of high and big die plate deformation of timbering monitoring device, it is characterized in that: comprise scaffold tubes, conduit and red laser pen, described red laser pen is fixed in described conduit, described conduit is placed in described scaffold tubes, be provided with filling material between described conduit and scaffold tubes, described scaffold tubes outside is provided with fastener.

Fig. 2 is test structure figure of the present utility model;
Fig. 3 is trystate figure of the present utility model;
Fig. 4 is application structure figure of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiments.Shown in Fig. 1 and Fig. 4, the utility model provides a kind of high and big die plate deformation of timbering monitoring device, comprise scaffold tubes 1, conduit 2 and red laser pen 3, described red laser pen is fixed in described conduit, described conduit is placed in described scaffold tubes, be provided with filling material 4 between described conduit and scaffold tubes, described scaffold tubes outside is provided with fastener 5.The two ends of described conduit and scaffold tubes are filled with mortar.Label layer 6 is scribbled outside described scaffold tubes.The length of described scaffold tubes is 3 meters.
Because the hot spot of ruddiness pen is comparatively large, remote observation precision can decrease.For this problem, again the setting of laser instrument is done and a bit improved, original 1m scaffold tubes is changed into 3m pipe, front end and intended deformations larger portion position locking, rear end rotary buckle and intended deformations smaller part position locking, even if there occurs very little distortion like this, because the angle of steel pipe there occurs change, the survey station of the laser projected outside 30 ~ 50m can occur obviously to conjugate, the amplitude of deformation that the slight change that long distance is exaggerated angle is reacted.Because the position of observation station and survey station is all planned in advance, the hot spot displacement amplitude caused by practical distortion can be simulated in advance in CAD, and make corresponding scoring ring radius according to alarming value.The deformation accuracy that certain this method is measured is still lower, but our object be find cave in sign and and alarm, so this precision enough technician make accurate judgement.
Method for making: the utility model uses a red laser that can use source interface, (a green glow price is more expensive, and thermal value is 10 times of ruddiness, can not continue to light, therefore will select red laser pen).Owing to being low pressure low current, common telephone wire can be used as power lead.Prepare the long common scaffold tubes of a 1m again, the orange paint that on pipe, brush is eye-catching, and paste " No. 0 observation station " mark.A PVC conduit also can be overlapped again in inside, and fill up polyphenyl or other light filling things between pvc pipe and steel pipe, gap between two ends fills mortar, also can use additive method, as long as fixed by this bimetallic tube.Laser pen is filled in the pvc pipe one section of internal layer, laser pen clamping plug sternly allows it motionless by available batten or paperboard strip.Power lead passes the power supply connecting far-end from the other end of pvc pipe.So easy laser beam emitting device has just completed.
As shown in Figures 2 and 3, test method, the utility model steel tube fastener has set up height 1.5m, and span is about " desk " of 6m as bearing platform 7, directly be locked on the leger of bearing platform with fastener by the short scaffold tubes that laser instrument is housed, position is out of shape maximum at span centre.Opening laser instrument regulates brightness to reduced levels (reduction thermal value), red hot spot is found with a black flour plywood form 8 in the place of distance 20m, template is fixed well at firm position rack, as survey station, then by target paper printed in advance, paste after target center aims at hot spot or fix in template with drawing pin, the dark-coloured art paper of target, do not use white printer paper, avoid strong reflective dazzling.The size of the different radii mark distortion of scoring ring, inner ring is spot diameter, and outmost turns scoring ring is that preset alarm withdraws value.After all completing, start in " desk " upper loading, because span is very large, single steel pipe has found out obvious downwarp at once.And the hot spot on target deviate from target center as in anticipation, and reach alarming value very soon.
The above is feasible under test conditions, if but input practicality still has the problem that need solve.Topmost problem is that most of common laser pen can not continually be lighted (as 24 hours), can burn laser instrument like this.We have pulled down the laser instrument on a written-off optical lasers transit, and it is no problem that this laser instrument precision is high, far firing range and can continuing is lighted, but such laser equipment is somewhat expensive.Taking in building site to tear open in operation has just lost more than gain once damage.If but do not require 24 hours to continue start, such as same position to be measured is equipped with two ruddiness pens, alternately lights by conputer controlled power settings, just can effectively address this problem.
Compared with prior art, the utility model possesses following advantage, by this device with laser instrument, the safety zone far away in distance high-supported formwork district arranges receiving target, if support body there occurs distortion, facula position on receiving target is bound to change, if the warning amplitude that amplitude of variation exceedes setting in advance just gives the alarm, stops pouring into a mould and allowing workmen withdraw.Laser instrument price is not high, can Reusability.Want to observe how many points just arrange how many laser instruments, no matter where, as long as find the gap between the vertical rod of support body horizontal vertical accurately, laser just can wear out in the position of observation station.Round-the-clockly can observe, be particularly useful for the engineering of casting concrete at night.Observation personnel close to formwork district, by seeing the hot spot just energy judge templet deformation of projection, both a people need not can observe multiple spot simultaneously, also can many people observing a bit simultaneously.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
