Description

Technical Field

[0001] The present invention relates to the field of elevator shaft construction, and particularly to an elevator shaft verticality adjusting device and a construction method thereof. Background Art

[0002] Since the verticality of the elevator shaft has a great influence on the installation of elevator equipment in the later stage and its later use, the construction verticality requirements for the elevator shaft are relatively high during elevator shaft construction. Generally, the verticality is required to be controlled within 0 to +50 mm, and the requirements are often higher in super high-rise projects. In addition, since the construction of super high-rise elevator shafts usually uses a tube formwork for construction, the construction environment is relatively enclosed and the operating space is limited. Therefore, it is difficult to control the verticality of the elevator shaft during construction. In traditional construction methods, measurement methods such as gravity plumb bobs are mostly used, with low construction efficiency and difficult to ensure construction quality.

The formwork support unit is connected to the wall, the formwork frame unit is arranged inside the formwork support unit, and the relative position between the formwork frame unit and the formwork support unit is adjusted through the adjusting unit.

[0006] The laser measurement unit includes a laser emitting device and a laser receiving device.

The wall bolts pass through the formwork support unit, the electric bolt adjusting device can adjust the screwing-in amount of each wall bolt, and the first control box receives the signals of each laser receiving device and provides input signals for the electric bolt adjusting device.

[0009] Preferably, the adjusting unit further includes 4 verticality sensors fixed on the formwork support unit, with 1 verticality sensor corresponding to each of the four walls. Each verticality sensor is respectively connected to the first control box in signal.

[0010] Preferably, there are 8 wall-through bolts, with 2 wall-through bolts corresponding to each of the four walls, and the two wall-through bolts on the same wall are distributed vertically.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In order to more fully describe the technical solutions of the above invention, specific embodiments are listed below to prove the technical effects; it should be emphasized that these embodiments are used to illustrate the present invention and not to limit the scope of the present invention.

[0032] The elevator shaft verticality adjustment device provided by the present invention is as Figures 1 to 3As shown in the figure, it includes a bobbin mold unit and a laser measurement unit. The bobbin mold unit includes a formwork support unit 10, a formwork frame unit 20, and an adjustment unit 30. The formwork support unit 10 is connected to the wall. The formwork frame unit 20 is arranged inside the formwork support unit 10, and the relative position between the formwork frame unit 20 and the formwork support unit 10 is adjusted through the adjustment unit 30. The main body of the formwork frame unit adopts a steel profile frame, which is stable and durable. The laser measurement unit includes a laser emission device 41 and a laser reception device 42. There are at least 3 laser emission devices 41, which are fixedly installed on the shear wall 01 at the bottom of the elevator shaft. There are 4 laser reception devices 42, which are respectively fixedly installed at the four corners of the bottom of the formwork frame unit 20 to ensure that each laser reception device 42 can receive laser signals within a certain range. The laser reception devices 42 are respectively signal-connected to the adjustment unit 30. When the laser reception device 42 receives the laser emitted by the laser emission device 41, the position information and verticality information of the formwork frame unit 20 can be obtained through information processing, and then the verticality adjustment of the formwork frame unit 20 is completed through the adjustment unit 30. The operation is simple, the accuracy is high, and the safety is good.

[0033] Preferably, please refer to Figure 1 and Figure 2 in particular. The adjustment unit 30 includes a plurality of wall-through bolts 31, an electric bolt adjustment device 32, and a first control box 33. The wall-through bolts 31 pass through the formwork support unit 10. The electric bolt adjustment device 32 can adjust the screwing-in amount of each wall-through bolt 31, and then control the position of the formwork frame unit 20 in contact with the end of the wall-through bolt 31. The first control box 33 receives the signals of each laser reception device 42 and provides input signals for the electric bolt adjustment device 32. In other words, the first control box 33 uses the signals of the laser reception devices 42 as input signals and outputs control signals for the electric bolt adjustment device 32, with high control accuracy and the ability to avoid errors caused by manual operation.

[0034] Preferably, please continue to refer to Figure 1 and Figure 2 in particular. The adjustment unit 30 further includes 4 verticality sensors 11 fixed on the formwork support unit 10, with one verticality sensor 11 corresponding to each side of the four walls. Each verticality sensor 11 is respectively signal-connected to the first control box 33. In this application, the verticality of the formwork frame unit 20 is measured based on the formwork support unit 10, and the verticality of the formwork support unit 10 can be guaranteed by the verticality of the shear wall 01, ensuring the accuracy of the measurement.

[0035] Preferably, please continue to refer to Figure 1 and Figure 2, for each position of the formwork unit 20, there are 8 through-wall bolts 31, with 2 through-wall bolts 31 provided corresponding to each side of the four walls, and the two through-wall bolts 31 on the same wall are distributed vertically, so as to ensure that the adjustment of the formwork unit 20 can meet the construction requirements.

[0036] Preferably, please continue to refer to Figure 1 and Figure 2 , the laser receiving device 42 is connected to the first control box 33 and is used to control the 4 through-wall bolts 31 located at the lower part of each wall; the verticality sensor 11 is connected to the first control box 33 and is used to control the 4 through-wall bolts 31 located at the upper part of each wall. Specifically, during construction, the 4 through-wall bolts 31 at the lower part can be adjusted according to the signal of the laser receiving device 42 to adjust the position of the formwork unit 20. After the position is fixed, the 4 through-wall bolts 31 at the upper part can be adjusted according to the signal of the verticality sensor 11 to adjust the verticality of the formwork unit 20. The operation is convenient and the accuracy is high.

[0037] Preferably, please continue to refer to Figure 1 and Figure 2 , the formwork unit 20 further includes a climbing mechanism. The climbing mechanism includes a second control box 21 and a climbing track 22 installed on the wall. The second control box 21 controls the formwork unit 20 to lift along the climbing track 22. That is to say, the formwork unit 20 climbs in a track type, with high safety and automated operation, reducing the construction difficulty. Preferably, a limiter and an anti-falling device are further provided on the climbing mechanism to further improve safety.

[0038] Preferably, the laser emitting device 41 includes a base (not shown) that can be adjusted horizontally and a laser emitting light source (not shown) installed on the base. For example, it can be observed whether the bubble in the base is centered to adjust whether the base is in a horizontal state, so as to ensure that the laser emitting device 41 is horizontal, that is, the emitted laser is in the vertical direction; the laser emitting light source can rotate to emit laser, so that the laser receiving device 42 can receive the laser on a straight line, avoiding the laser being a fixed point, which is difficult to align and adjust; in addition, when using it next time, turn on the laser power supply and simply recheck to be able to use it normally.

[0039] The present invention also provides a construction method of an elevator shaft verticality adjustment device as described above, including the following steps:

[0040] S1: Perform positioning and lofting at the bottom of the elevator shaft, and obtain 4 control lines 02 for the verticality of the elevator shaft by taking about 10 cm away from the shear wall of the elevator shaft, as Figure 3 shown;

[0041] S2: At least three of the laser emitting devices 41 are installed at the bottom of the elevator hoistway, such that the three laser emitting devices 41 are respectively located at the middle of a control line 02, as shown in Figure 3 and the levelness of the laser emitting devices 41 is adjusted. For example, the base is adjusted to center the bubble to ensure that the laser emitting devices 41 emit vertical lasers that coincide with the control line 02. Preferably, after the laser emitting devices 41 are installed in step S2, protective measures can also be taken for the laser emitting devices 41. For example, soft and hard floor protections are set at about 10 cm away from the shear wall 01. While achieving protection, it is ensured that the emitted lasers are not blocked.

[0042] S3: After the relative height between the formwork unit 20 and the formwork support unit 10 is adjusted, the laser emitting devices 41 are turned on. The adjustment unit 30 adjusts the position and perpendicularity of the formwork unit 20 according to the laser signals received by the laser receiving devices 42. The specific adjustment method can be as follows: First, the four wall-piercing bolts 31 at the lower part are adjusted according to the signals of the laser receiving devices 42 to adjust the position of the formwork unit 20. After the position is fixed, the four wall-piercing bolts 31 at the upper part are adjusted according to the signals of the perpendicularity sensors 11 to adjust the perpendicularity of the formwork unit 20.

[0043] S4: After positioning is completed, the wall-piercing bolts 31 are adjusted to fix the relative positions of the formwork unit 20 and the formwork support unit 10. After positioning and perpendicularity verification, preparation for concrete pouring is made.

[0044] S5: After the concrete pouring is completed and the formwork can be removed, the relative height between the formwork unit 20 and the formwork support unit 10 is adjusted. Specifically, the wall-piercing bolts 31 are loosened, and the second control box 21 is started to make the formwork unit 20 climb upward along the climbing track 22. Steps S3 to S4 are repeated to start the construction of the next standard floor until the construction of the elevator hoistway is completed.

[0045] This method is simple in construction, high in safety, and has relatively low requirements for the construction environment.

[0046] In summary, the elevator shaft verticality adjustment device and its construction method provided by the present invention. The device includes a cylinder formwork unit and a laser measurement unit. The cylinder formwork unit includes a formwork support unit 10, a formwork frame unit 20, and an adjustment unit 30.
