Description

  The present invention relates to construction management technology in the construction technology field based on level detection.

In the construction field, horizontal control is an important elemental technology, such as finishing the concrete surface cast for building floor construction horizontally. Techniques for measuring the horizontal include angle level measurement using a bubble-filled level, total station, and measurement using a laser. In the construction field, height management such as horizontal is used as construction management technology, such as horizontal installation of concrete placing surfaces, pillar management, and beam inclination.
For example, in Patent Document 1 (Japanese Patent Laid-Open No. 7-18861) and Patent Document 2 (Japanese Patent Laid-Open No. 3-69759), a laser transmitter placed on the floor and a floor concrete placing and leveling machine were installed. An apparatus for performing level control of a concrete placing floor by a receiver is disclosed.
In the invention described in Patent Document 3 (Japanese Patent Application Laid-Open No. 7-208983), a technique that enables leveling while measuring a level by installing a laser light emitter and attaching a light receiver to the leveler. The light emitter is installed outside the leveling surface, and it is necessary to install a plurality of light emitters to cover the entire leveling surface. Measurement is not possible due to obstruction, and the measurement efficiency also decreases.
Patent Document 4 (Japanese Patent Application Laid-Open No. 2011-153423) uses a technique in which a laser is rotated and projected to the surroundings, where a light emitter is installed outside the leveling surface and there are people around the surface. Cannot be measured because the laser is blocked. Since these techniques do not record measurement results, it is not possible to record the progress.

1. In construction technology, level detection is a basic technology, and level detection using a barometric pressure sensor does not require the use of a total station or laser, and the level at which the barometric pressure sensor is located is not affected by the line of sight. Can be detected.
2. By comparing the atmospheric pressure data measured at the reference point with the atmospheric pressure data measured at other points, it is possible to grasp the height difference and the inclination. The detected atmospheric pressure data can be converted into “millimeter” or the like, or displayed as atmospheric pressure data itself.

The present invention is an invention in which a barometric pressure sensor is installed in a building or structure under construction, a construction machine, an instrument, etc., and construction management is performed by detecting elevation and inclination using measured atmospheric pressure data. At the construction site, if the numerical value of the measured atmospheric pressure is basically the same, the invention is applied to the field of architecture and civil engineering, focusing on showing the same level. A small and highly accurate barometric sensor having a temperature correction function and the like has been developed, and attention is paid to the use thereof.
In the construction field, horizontal and vertical are the most basic elements, and level adjustment greatly affects construction accuracy. Generally, measurement is performed using a surveying technique or a laser. These techniques need to be able to see the measurement location, and it is difficult to obtain measurement information in real time. For example, when constructing concrete floors, it is necessary to measure at intervals and intermittently perform leveling for adjustment for unevenness. . In the floor construction of a large area, it is difficult to go into and out of the adjustment point, which is a time-consuming work.
In the present invention, by mounting a small and high-precision barometric sensor on a building frame or construction equipment, the level of the place where the barometric sensor is located is always grasped and utilized for construction management of construction work.

The present invention installs atmospheric pressure sensors at a plurality of measurement target locations on a construction site, obtains atmospheric pressure data from these atmospheric pressure sensors, and uses the obtained multiple atmospheric pressure differences between locations where atmospheric pressure sensors are installed. This is a construction height management method for obtaining a difference in height or inclination of the building. It can also be used for a method of detecting the height by using a certain pressure sensor as a fixed point as reference data and providing another pressure sensor in a construction work device to obtain a difference from the location where the device exists. Further, in a moving work device, a means for grasping the position of the work device such as a position detection sensor and an atmospheric pressure sensor can be used in combination to detect the trajectory of the work device and the height of the moving surface.
Although the required accuracy differs depending on the work, the floor finishing work can be managed with a height resolution of 1 mm and a coordinate resolution of about 1 cm.

This construction height management method consists of these atmospheric pressure sensors, if necessary, various sensors such as position detection sensors, work equipment, recording / analysis / control devices, display devices, wireless LAN, etc. It is summarized in the construction management system. A system that measures height and position information with high accuracy in real time can be obtained by using a camera image viewed from the level of the height measurement sensor and the position measurement sensor.
Position information is measured and recorded using a camera, GPS, beacon, WIFI, or the like as a position detection sensor.
The place where the atmospheric pressure sensor is installed is the floor, beam, deck plate, ground leveling under construction, and the construction equipment such as dredging, dragonfly, floor finishing robot, heavy equipment for leveling, etc. Work.
For example, a floor finishing robot equipped with an atmospheric pressure sensor and a position detection sensor can perform leveling processing that reflects irregularities in real time. Work efficiency increases and finishing accuracy also increases.
In the present invention, the level measurement result can be notified to the measurer immediately using the numerical value, sound, light and the like on the spot. Since the level measurement result and measurement position can be recorded and displayed immediately on a portable terminal or the like, the finish can be confirmed immediately, and immediate measures such as correction can be taken. The measurement position and measurement result can be recorded as numerical information.

The main fields of application of the present invention are as follows.
(A) Measure the level when placing concrete slabs.
By performing level measurement continuously, it becomes possible to level the level accuracy of the entire floor well.
(B) In the construction considering the shape change during construction such as a beam, the height is measured when necessary.
Appropriate peeling can be set in consideration of deformation due to its own weight.
(C) Always measure the deflection of the slab deck.
It is possible to detect deformation that sags due to deflection and improves quality and detects fall (risk).
(D) After construction of the concrete slab, measure the finished shape.
Continuous measurement can be easily performed, and high-precision construction management is possible.
(E) Others A barometric pressure sensor is installed in the stripped part of a reinforcing bar or RC beam to measure the height.
When installing base materials, sashes, doors, and furniture, measure the floor and mounting height.

Looking at the height state displayed on the monitor 41, the operator 56 operates the controller 56a to steer the floor finishing robot 7 and adjust the leveling work as needed.
FIG. 1B shows an example in which the height difference of the concrete placing surface 53 is divided into meshes and a height difference of 5 mm or more is displayed with respect to the reference surface. The operator sees this state and operates the floor finishing robot to perform the leveling work within the standard.

The embodiment regarding the floor slab concrete placement construction management system using a dragonfly and a trowel is shown in FIGS. This is an example in which a register mark or scissors provided with an atmospheric pressure sensor is used instead of the floor finishing robot used in the first embodiment.
Examples of leveling dragonflies and trowels used in this embodiment are shown in FIGS.

<Embodiment 3: Construction management system applied to a building frame as a construction frame>
When building a building, it is fundamental to assemble a building frame consisting of pillars and beams. If this basic frame is distorted, the building will be defective, so the horizontal and vertical of the frame are important construction management elements. This management is also proceeding with confirmation using surveying technology, etc., but has the same problems as described above.
In this embodiment, a construction management system and a management method for installing and managing a pressure sensor and a positioning sensor on a beam are used.
A simple model of the frame and an example of sensor arrangement are shown in FIG. FIG. 8A shows a building under construction at the construction site 100, and four columns 61a, 61b, 61c, 61d and five beams 62a, 62b, 62c, 62d, 62e between and between the columns.

FIG. 8B shows an example in which barometric pressure data observed by the barometric sensor linked to the positioning sensor is converted into a height display and displayed in mm units at the frame plane and at each sensor position.
When the deviation exceeding the allowable range occurs while viewing this display data, the height adjustment work is performed.

<Embodiment 4: Construction management system applied to the back surface of the deck plate>

The deck plate and slab have their own weight, finishing material load, floor load, and so on.
Since the deck plate is a bent steel plate, concentrated raw concrete concentrates, and concentrated load is generated, which may cause the deck plate to bend more than expected and collapse. It is a system that observes and manages.

FIG. 9A shows a situation where the deck plate 52 laid on the beam is viewed from the lower floor. A level sensor 16 and a positioning sensor 2 using an atmospheric pressure sensor are installed on the back surface of the deck plate. In this example, both sensors are arranged in the center section divided by the beam so as to detect bending.
This embodiment also includes a relay device for data obtained from the sensor, a PC for processing and calculating data, and a monitor for displaying deflection.

The state before placing the ready-mixed concrete on the deck plate 52 is used as a reference state, and the pressure sensor data is used to measure the amount of subsidence that the deck plate is bent and deformed after placing the concrete.
FIG. 9B shows a display screen example 42 in which the concrete placement surface on which concrete is placed is mapped and the amount of settlement is displayed. In this display example, the deflection is managed in units of 5 mm.

By using a positioning sensor that detects a position and an atmospheric pressure sensor in combination with the moving body, it is possible to detect a realistic height change along the movement trajectory.
Therefore, the present invention has the following remarkable effects.
By using it to measure the finished shape after placing concrete slabs, it is possible to easily measure the unevenness of the flat surface and save it as electronic data, which makes it easy to manage quality control data.
It is possible to install a pressure sensor and a positioning sensor on a concrete leveler and level it while measuring the level during placement.
The level measurement result can be notified to the measurer on the spot using numerical values, sound, light, and the like.
The level measurement result and measurement position are recorded and displayed immediately on a portable terminal or the like, the finish can be confirmed immediately, and correction and other immediate measures are possible.
The measurement position and measurement result can be recorded as numerical information.
By installing it on the beam, deformation can be measured constantly, and easy and highly accurate construction management is possible.
By installing it at the bottom of the deck plate, it is possible to perform safe construction by constantly monitoring the subsidence state during slab placement.
