The invention will be further elucidated and described with reference to the drawings and embodiments. The utility model discloses in the technical characteristics of each embodiment under the prerequisite that does not conflict each other, all can carry out corresponding combination.

As shown in fig. 1-3, for the utility model discloses a synchronous measuring device for component promotes in-process that provides in a preferred embodiment, the device is used for realizing carrying out the single-point observation to the promotion component 7 that upwards promotes in the construction. Its essential element can divide into flexible scale 6 and measurement base, and common steel tape measure or dish chi in the flexible scale 6 can adopt the construction, and the measurement base then can utilize common structural component on the construction site to assemble, its detailed structure of following specific description.

The main body of the measuring base is a steel seat beam 1, the top surface and the bottom surface of the steel seat beam 1 are both planes, and the steel seat beam 1 can be directly made of I-steel in the embodiment. The bottom surface of the steel seat beam 1 needs to be provided with at least one base fixing piece 2 for fixing the steel seat beam 1 on the terrace 9. Generally, the base fixing member 2 can be realized by using expansion bolts, when the upper member needs to be observed at a certain position, the measuring base can be moved to the position, then the expansion bolts are used for penetrating through screw holes on the bottom surface of the steel seat beam 1 and being driven into the terrace 9, so that the base fixing member 2 and the steel seat beam 1 are fixed, and the base fixing member 2 can be separated from the steel seat beam 1 again after the observation is finished. Of course, in some fields which are not suitable for anchoring by expansion bolts, the temporary fixation of the steel seat beam 1 can be realized by directly ballasting the bottom plate of the steel seat beam 1 by using a heavy object.

A group of ruler reading external members are arranged on the top surface of the steel seat beam 1 and can be installed on the top of the flange plate on the upper portion of the I-shaped steel. The ruler set comprises a lower support part 3, an upper support part 4, a sleeve 5 and a ruler reading mark 10, wherein the lower support part 3 and the upper support part 4 both adopt round steel in the embodiment, and other rigid structural parts such as round steel tubes and square steel tubes (the lower support part 3) can completely meet the use requirements. Referring to fig. 3, two round steel bars as the lower support members 3 are coaxially welded and fixed to the flange plate of the i-shaped steel at a certain interval, and two ends of a round steel bar as the upper support member 4 are welded to the two round steel tubes of the lower portion, thereby forming a bridge structure. Thus, a gap is formed between the two lower supporting pieces 3 and the upper supporting piece 4 and the top surface of the I-shaped steel, and the gap is used for the flexible graduated scale 6 at the high position to pass through. In the device, in order to play the effect of falling the chi and prevent that flexible scale 6 from breaking, can establish a sleeve pipe 5 at the outside cover of upper portion support piece 4, be convenient for flexible scale 6 to walk around smoothly when protecting flexible scale 6. The sleeve 5 may be made of circular PVC or steel pipe, and its surface should be smooth to reduce the friction with the flexible scale 6. The sleeve 5 and the upper support 4 may be fixed by welding, gluing, etc. After the sleeve 5 is sleeved, a gap for the flexible graduated scale 6 to pass through is still formed between the lower part of the lower support 3 on the two sides of the sleeve 5 and the top surface of the steel seat beam 1.

Referring to fig. 1, one end of a flexible graduated scale 6 is fixed on a lifting member 7 to be measured through a connecting piece 8, and the other end of the flexible graduated scale is horizontally tensioned on the top surface of the steel seat beam 1 after being attached to the surface of the sleeve 5 and turned. The connecting piece 8 can be a round steel elbow, is fixed at the target measuring position of the lifting component 7 to be measured, and the end part of the flexible graduated scale 6 is bound or clamped and fixed on the round steel elbow before the component is lifted.

In the synchronous measuring device, the free end part of the flexible graduated scale 6 positioned on the ground can apply proper tension force, so that the horizontal section above the I-steel is tensioned, and the reading accuracy is ensured; simultaneously under the guide of steel saddle roof beam, transmit tensile force to perpendicular unsettled flexible scale 6 sections on, make flexible scale 6 begin to produce tensile force to the unsettled section between the connecting piece 8 from the perpendicular mark 11 position of scale, the scale can utilize its self tensile force to improve its stability from this, avoids appearing rocking, and the influence to the steel rule such as wind-load when the elimination of maximize distance is higher.

The synchronous measuring device in the above embodiment is only provided with one set of reading rule suite, so that only single-point observation can be realized. However, in some construction scenarios, the large span structures such as the net rack, the air corridor, the steel truss and the like need to be synchronously observed in the whole lifting/jacking process. Generally, in the implementation process of the construction schemes, in order to prevent large deflection deformation or initial stress concentration, the requirements of synchronism and structural deformation limitation are placed on a plurality of structural key positions, and therefore the requirement of simultaneous observation of multiple points is generated. The utility model discloses on the basis of above-mentioned embodiment, can further arrange the multiunit on 1 top surface of steel seat roof beam according to site conditions and technical requirement and read the chi external member, realize the multiple spot and survey the use simultaneously, its device basic structure is similar with preceding embodiment, and the difference only lies in on 1 top surface of steel seat roof beam and has arranged the multiunit and read the chi external member.

The angle and direction of the upward extension of the different flexible scales 6 can be different, but the horizontal sections of the upward extension of the flexible scales on the top surface of the steel seat beam 1 after passing through the sleeve 5 are preferably kept horizontally tensioned, and the distance between the horizontal sections is not required to be too large. Referring to fig. 6, the same upper round steel can be erected on the multiple groups of reading rule kits through the multiple lower round steels, and the upper round steel and the lower round steel are arranged vertically or horizontally. Then two adjacent lower round steel and the upper round steel section of top constitute a set of support frame of reading the chi external member, and independent PVC sleeve pipe or circular steel tube are established as reading the chi guide rail to each section upper portion round steel outside cover.

Multiple sets of scale kits may share the same scale mark 10 to facilitate the observation of synchronicity and structural distortion at key locations of different structures. In addition, in order to ensure the accuracy of reading, in the multiple sets of reading ruler sets, the size of the sleeves 5 is preferably the same, and the distance between the sleeves and the top surface of the steel seat beam 1 is the same.

Of course, except for the cases shown in fig. 4 to 6, the ruler sets can also adopt independent multi-group parallel arrangement forms, so that the ruler sets can be flexibly added when observation points need to be added temporarily.
