Description

Technical Field

[0001] The utility model specifically relates to a transverse position indicating air-filled bag column adapted for measuring inside a corridor. Background Art

[0002] During the building renovation process, when measuring the building floor height and it is impossible to enter the room for measurement, it is necessary to measure the span, depth and floor height of the building through the stairwell. Usually, the floor height of the two platforms at the upper and lower vertical positions can be directly measured in the case of two flights of stairs. When encountering a three-flight staircase, when there is a non-positive vertical correspondence between the top surface and the bottom surface of the floor, usually the position can only be estimated by the surveyor holding the distance meter. It is difficult and difficult to measure at home. Even if it is possible to measure at home, only the distance between the bottom surface of the upper floor slab and the top surface of the lower floor slab can be measured. This measurement method also has disadvantages. The lack of a floor thickness makes it impossible to directly obtain the floor thickness value. Due to the different types of renovated buildings and the differences in design structures, there are differences in floor height. The stairwell floor height lacks an equivalent part that can be guided to the specified measurement position, making it difficult to directly and accurately obtain the floor height measurement data. There is a lack of relevant auxiliary tools that can adapt to the emergency and on-demand adjustment of existing measuring instruments to obtain the vertical measurement point position. Utility Model Content

[0003] In order to overcome the defects of the prior art, a lateral position indicating air bag column adapted for measurement inside a corridor is provided to solve the above problems.

The air bag column is arranged vertically, the lower end of the air bag column is fixedly connected to the chassis, the upper end of the air bag column is provided with a light emitting reference plate, the light emitting reference plate comprises a sheet-like bag body and a first semiconductor laser component, the bottom surface of the sheet-like bag body is a first measuring reference surface for matching a measuring instrument, the outer wall of the sheet-like bag body is provided with a first semiconductor laser component, and the light emitting port of the first semiconductor laser component is arranged toward the wall surface where an entrance door is located.

[0005] The beneficial effects of the utility model are:

[0006] The utility model is used in the work of acquiring building data in the renovation project of old residential areas. It can realize accurate vertical measurement in the corridor without entering the house, and cooperate with the measuring instrument to provide data at any vertical position to provide a horizontal reference position. It is simple to operate and convenient to change positions.

[0028] Specific embodiment five: This embodiment is a further limitation of specific embodiments one, two, three or four, the airbag column 2-2 includes a main airbag column 2-2-1, a sub-airbag column 2-2-2 and an annular adhesive sheet 2-2-3, the main airbag column 2-2-1 and the sub-airbag column 2-2-2 realize a staged use process, wherein the main airbag column 2-2-1 is vertically arranged below the sub-airbag column 2-2-2, the lower end of the main airbag column 2-2-1 is fixedly connected to the chassis 2-1, the upper end of the main airbag column 2-2-1 is coaxially provided with an annular adhesive sheet 2-2-3, the lower end of the sub-airbag column 2-2-2 is connected to the upper end of the airbag column 2-2-1 through the annular adhesive sheet 2-2-3, and the upper end of the sub-airbag column 2-2-2 is provided with the light emitting reference plate 5. An adhesive sheet bonded to the annular adhesive sheet 2-2-3 is provided on the light emitting reference plate 5. When it is necessary to start the inflation of the sub-sac column 2-2-2, the annular adhesive sheet 2-2-3 is separated from the adhesive sheet to release the sub-sac column 2-2-2. When it is not necessary to start the inflation of the sub-sac column 2-2-2, the annular adhesive sheet 2-2-3 is bonded to the adhesive sheet, and the sub-sac column 2-2-2 in the squeezed and folded state is squeezed into the main capsule column 2-2-1.

[0029] Furthermore, inflation and deflation holes are respectively provided on the main bag column 2-2-1 and the auxiliary bag column 2-2-2 to realize inflation in stages as needed. When the main bag column 2-2-1 still fails to reach the predetermined reference position for measurement after being inflated to the maximum limit height, the auxiliary bag column 2-2-2 is started to inflate, thereby achieving the effect of extending its own height for a second time, thereby assisting the main bag column 2-2-1 to reach the predetermined height. By overlapping the heights of the main bag column 2-2-1 and the auxiliary bag column 2-2-2, it can be ensured that the bag column 2-2 is adapted to measure buildings at different heights, thereby improving the universal performance of the utility model.

[0030] Furthermore, the maximum limit height of the main column 2-2-1 in the inflated state is 1.5m, and the maximum limit height of the auxiliary column 2-2-2 in the inflated state is 0.3m, so that the main column 2-2-1 and the auxiliary column 2-2-2 can cooperate to adapt to various residential building types with different heights.

[0031] When the utility model is used for field measurement in a building with a floor height of 3m, the main bag column 2-2-1 needs to be opened, and the auxiliary bag column 2-2-2 does not need to be opened. Only the main bag column 2-2-1 needs to be inflated. The top of the main bag column 2-2-1 is provided with an uninflated auxiliary bag column 2-2-2 and a light emitting reference plate 5. The light beam emitted by the light emitting reference plate 5 is irradiated on the root of the wall 21 where the entrance door is located until the light beam emitted by the light emitting reference plate 5 is ensured to be flush with the horizontal ground 22 where the entrance door is located, and then the main bag column 2-2-1 can be stopped from being inflated.

[0032] When the utility model is used for field measurement in a building with a storey height of 3 to 3.6 m, it is necessary to inflate the main bag column 2-2-1 and the auxiliary bag column 2-2-2 at the same time. The inflation order is to inflate the main bag column 2-2-1 first, and then inflate the auxiliary bag column 2-2-2.

The main bag column 2-2-1 and / or the auxiliary bag column 2-2-2 can be stopped from being inflated until the light beam emitted by the light emitting reference plate 5 is flush with the horizontal ground 22 where the entrance door is located.

[0033] Furthermore, the height of the auxiliary column 2-2-2 ranges from 0 to 30 cm. The auxiliary column 2-2-2 is activated as needed in case of emergency when the floor height is higher than 3 m.

[0034] Furthermore, the outer diameter of the auxiliary column 2-2-2 is smaller than the outer diameter of the main column 2-2-1. This arrangement is to ensure support and height enhancement while reducing the pressure on the main column 2-2-1. In addition, the different diameters can also ensure that surveyors can quickly identify the floor height specifications of the building being measured.

[0035] Specific embodiment six: This embodiment is a further limitation of specific embodiments one, two, three, four or five. The main airbag column 2-2-1 in the airbag column 2-2 is formed by a plurality of columnar airbags arranged vertically in sequence along the height direction.

[0042] Furthermore, the bottom surface of the chassis 2-1 can be bonded with an adhesive layer after the positioning hoop 1 is pulled out. When the chassis 2-1 is taken out from the horizontal opening 4, it can be bonded to the horizontal surface at the step position or the stair turning position through the adhesive layer, further stabilizing the position of the chassis 2-1.

[0043] Furthermore, when the shape of the chassis 2-1 is elliptical, the corresponding transverse cross-sectional shape of the positioning hoop 1 is elliptical, which is used to adapt to stair handrail support rods 20 with different outer diameters to enclose and wrap them.
