Description

  The present invention relates to a building construction position confirmation method of a building, and more particularly, to a building construction position confirmation method using a GPS receiver including a GPS antenna and a GPS receiver and a computer in which drawing creation software is incorporated.

  For example, when a new residential building is constructed on a residential building site, a site survey is generally performed prior to the start of construction. In order to determine the position of the building on the site, a territorial rope is struck by hitting a small pile and laying a rope or string. Furthermore, as a temporary object for displaying the position, height, root cutting width, depth, and the like of the foundation of the building, an operation of installing a way of making consisting of a way pile and a way through is performed. In addition, as the foundation work of the building, ground work in which crushed stones and the like are spread on the roots and thrown away concrete, and work to install reinforcement, foundation formwork, etc. are performed.

  These operations will be performed with high accuracy while surveying by, for example, a plurality of workers, but in particular, for example, a housing development site has just been created and no buildings have been built around it. When there is only a slight amount, the site where the building is to be built may be misunderstood by misunderstanding the position of the boundary pile. In addition, information such as a significant change in the layout of the building may not be transmitted accurately, or the construction may be misunderstood while the building position of the building is largely incorrect due to a mistake in posting to the landline confirmation sheet, etc. is there.

  These fundamental construction errors are due to human errors and rarely occur, but once they occur, the foundation and building must be dismantled and replaced, resulting in enormous costs. As well as a major loss of trust. For this reason, it is desired to develop a method that can prevent such a human error. However, for example, only a method that requires a double or triple check is employed, and a double or triple method is also employed. Even with this check, human error is not completely prevented.

  On the other hand, a system has been developed in which a GPS receiver is used to confirm the soundness of a structure by confirming the position of a measurement point by receiving radio waves from a GPS satellite (for example, Patent Document 1). ).

The data including the information on the data is stored in the database unit, and predetermined information can be displayed on the display 15 or output from the printer.

  The GPS receiver 10 is a known device having a function of measuring the latitude and longitude of a measurement point by receiving radio waves from a GPS satellite 16, and includes a GPS antenna 11 and a GPS receiver 12, and further includes an operation A display unit 14 is provided. As such a GPS receiver 10, a product “NetSurv G6” (manufactured by Japan GPS Solutions Co., Ltd.), which is a first-class GPS surveying instrument certified by the Geospatial Information Authority of Japan, can be used.

  In the present embodiment, the GPS receiver 10 uses the data from the national electronic reference point network (see FIG. 3) managed by the Geospatial Information Authority / Japan Survey Association as correction data. It has a function to receive via the Japan Surveying Association, which makes it possible to measure the latitude and longitude of the measurement point more efficiently.

  Furthermore, in this embodiment, the GPS receiver 10 causes the operation display unit 14 to display measurement data related to the latitude and longitude of the measurement point measured by the GPS receiver 12 after receiving the radio wave by the GPS antenna 11. And can be transmitted to the computer 13 connected via the wired or wireless communication network 17 by an operation from the operation display unit 14.

  In this embodiment, at the time of surveying the site 20 where the residential building is built, as shown in FIG. 2, at least one point in the site is used as a reference point P 0, and the position coordinates based on the latitude and longitude of the reference point P 0 are obtained. Measured by the GPS receiver 10, the position coordinates are dropped on the site map on the drawing creation software, and the latitude and longitude of the required points of the residential building or site map designed on the drawing creation software are calculated and the computer 13 is stored.

  That is, in the site survey, as shown in FIG. 2, for example, the corner facing the road 21 of the site 20 where the partitioned residential building is to be constructed is selected as the reference point P0, and the reference pile is provided. A GPS antenna 11 and a GPS receiver 12 are installed at the reference point P0. If the GPS receiver 10 is operated after installing the GPS antenna 11 and the GPS receiver 12 at the reference point P0, the GPS antenna 11 receives radio waves from, for example, the GPS satellite 16 or the national electronic reference point network. In about 20 minutes, the position coordinates based on the latitude and longitude of the reference point can be easily measured with an accuracy of, for example, about ± 2 mm. The measured position coordinates can be appropriately displayed on the operation display unit 14 for confirmation, and can be transmitted to the computer 13 via the communication network 17 and taken into the computer 13 in which the drawing creation software is incorporated. It is like that.

  In addition, as a method of taking in the computer 13 the position coordinates based on the latitude and longitude of the reference point P0 measured by the GPS receiver 10, an external storage means such as a floppy (registered trademark) disk or a CD-ROM is used. It is also possible to adopt a method of taking in the position coordinates by directly inputting them into the computer 13 manually.

  In the present embodiment, the computer 13 incorporates drawing creation software. Drawing creation software is a well-known program software that has a function of creating a drawing by being incorporated in a computer, and has x-coordinates, y-coordinates, z-coordinates, etc. It can be created easily, and the position coordinates of each point on the drawing can be easily calculated. As such drawing creation software, for example, various known CAD software (JWCAD, AUTOCAD), draw software, paint software, and the like can be used.

  In this embodiment, the site map of the site 20 where the residential building is built is created on the drawing creation software of the computer 13, and corresponds to the reference point P0 of the created site map. The position coordinates based on the latitude and longitude of the reference point P0 captured by the computer 13 are dropped into the position. In addition, on the drawing creation software of the computer 13, a building design drawing is created while taking into consideration the layout of the building in the created site map, or a pre-created building design drawing is taken in, By arranging at a predetermined position, the work of determining the position of the building in the site map is performed.

  Furthermore, when the design position of the building in the site map is determined, as the required points P1, P2,... On the design map based on the position coordinates by the latitude and longitude of the reference point P0 dropped into the site map, for example, A plurality of points located at the boundary, for example, the position coordinates of the outer shape of the building drawn by the center line of the outer peripheral wall by the latitude and longitude of the corners and corners of the building are calculated, and these calculated required points P1 , P2..., The position coordinates based on the latitude and longitude are stored in the data storage unit of the computer 13 together with the position coordinates based on the latitude and longitude of the reference point P0.

  In this embodiment, when the ground rope or the way of spending is installed, as shown in FIG. 3, GPS reception is performed at a position considered to be the same as the reference point P0 or the required points P1, P2,. By installing the apparatus 10 and measuring the position coordinates according to the latitude and longitude, from the error between the measured latitude and longitude and the latitude and longitude of the reference point P0 or the required points P1, P2,. Check the position of the ground rope or how to spend.

  That is, when starting the construction work of a residential building, when the ground rope and the way of spending are installed, as shown in FIG. 3, for example, when the reference pile provided as the reference point P0 in the site survey remains, The GPS antenna 11 and the GPS receiver 12 are installed at the reference pile, and by receiving radio waves from the GPS satellite 16 and the national electronic reference point network, the position coordinates based on the latitude and longitude of this position are measured. The position coordinates based on the latitude and longitude of the position considered to be the same as the measured reference point P0 are taken into the computer 13, for example, and the position based on the latitude and longitude of the reference point P0 on the design drawing stored in the data storage unit A pass / fail determination is made as to whether or not the reference pile remaining on the site 20 can be used as it is as the reference point P0 as compared with the coordinates.

  Here, the position coordinates based on the latitude and longitude of the reference point P0 on the design drawing stored in the data storage unit of the computer 13 are preloaded into the operation display unit 14 of the GPS receiver 10 via the communication network 17. Thus, the pass / fail judgment of the reference point P0 can be quickly performed on the site 20. Further, when position coordinates based on the latitude and longitude of the position considered to be the same as the reference point P0 are taken into the computer 13 from the GPS receiver 10 via the communication network 17, the computer 13 determines whether the reference point P0 is acceptable or not. It is also possible to send the determination result back to the operation display unit 14 of the GPS receiver 10.

On the design drawing are the points and entering corner points, the GPS receiver 10 is installed on the actual site 20 at a position that seems to be the same as these required points P1, P2,. The position coordinates based on the latitude and longitude are measured, and the measured position coordinates are taken into the computer 13, for example, according to the latitude and longitude of the required points P1, P2,... On the design drawing stored in the data storage unit. Compared with position coordinates. Then, a new reference point P0 can be provided from the error of the compared position coordinates, and the position coordinates based on the latitude and longitude of the newly provided reference point P0 are set as the required points P1, P2,. It can be easily calculated from the coordinates of latitude and longitude measured at the same location.

  Furthermore, in this embodiment, the GPS receiver 10 is installed at a position considered to be the same location as the reference point P0 or the required points P1, P2,. By measuring the position coordinates, the position of the concrete, reinforcement, or foundation formwork is discarded from the error between the measured latitude and longitude and the latitude and longitude of the reference point P0 or the required points P1 and P2 stored in the computer 13 Can be confirmed.

  That is, in this embodiment, at the time of construction work, for example, the reference point P0 whose position is confirmed at the start of the construction work of a residential building, the newly established reference point P0, or the required points P1, P2,. The GPS receiver 10 is installed at the position considered to be the same location as the position coordinate by latitude and longitude, and the measured position coordinates are taken into the computer 13, for example, and stored in the data storage unit It is compared with the position coordinates based on the latitude and longitude of the required point on the figure. And it becomes possible to confirm easily the position of abandoned concrete, reinforcement, or a foundation formwork from the error of the compared position coordinates.

  In the present embodiment, the computer 13 in which the drawing creation software is incorporated can be used, for example, in a field office for building construction of a residential building. A portable computer 13 can also be brought into the site 20 for use. Furthermore, for example, it can be operated as a host computer provided at the head office and capable of comprehensively managing a large number of building works.

  Further, in the present embodiment, by incorporating various programs into the computer 13, the display 15 connected to the computer 13 has a construction management record screen as shown in FIG. Along with the figure, in the entry field 22 for filling in the latitude and longitude of the reference point calculated in the site survey and multiple required points, and at the time of setting up the rope or way of use, at the time of construction, construction of a residential building, etc. An actual measurement value entry field 23 for entering the actual measurement values of the latitude and longitude of the reference point and a plurality of required points, and an evaluation field 24 for displaying the evaluation results of these errors are displayed. It is also possible to promptly confirm the construction accuracy at the time of setting up the way of spending, at the time of construction work, for the construction of a residential building.

  Thus, according to the building position confirmation method of the present embodiment, at the time of surveying the site 20 where the residential building is built, at least one point is set as the reference point P0, and the position coordinates based on the latitude and longitude of the reference point P0 are obtained. While measuring with the GPS receiver 10, the latitude and longitude of the required points P1, P2 are calculated and stored in the computer 13, and the reference point P0 or the required points P1, P2 are set at the time of installation of the ground rope or way of use.・ Because work is done after confirming the latitude and longitude of, by managing the position of the site 20 and the building based on the information of the latitude and longitude measured using the GPS receiver 10, human error It is possible to effectively avoid a large error in the building position of the building.
