Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruler for measuring a deviation amount of a structure position, and in particular, it can easily measure a deviation amount from a reference position of a pile installed in the ground or a sewer pipe installed in a trench. At the same time, the present invention relates to a ruler for measuring the amount of deviation of a structure position, which allows the amount of deviation to be easily confirmed even by a construction photograph taken.

[0002]

2. Description of the Related Art In pile foundation work, the construction accuracy of piles is indicated by a control allowance value on the design drawings and specifications, and the flatness of the design reference position is determined by the finished shape inspection at the pile head position. The amount and direction of such a positional shift (hereinafter, such a positional shift amount is referred to as a deviation amount) is checked.
In the conventional measurement of the deviation amount of this pile P, as shown in FIG.
The reference lines 51, 52 in the direction orthogonal to the Y-axis are marked out, and the reference lines 51, 52 or the water thread stretched above the reference lines 51, 52 (stretching is used as a reference for surveying and position indexing). Of synthetic fiber made of synthetic fiber), the component deviations ΔX and ΔY of the pile core and the X and Y axis reference lines 51 and 52, respectively, are measured to obtain the measured value, and further calculated. Center deviation amount Δ (deviation between pile core and reference core)
Was calculated. In addition, in the work form management record, the construction photo of each pile after construction is recorded as a work form inspection photo.

[0003]

By the way, when the construction management as described above is performed, the central deviation amount indicating the positional deviation of the constructed piles is left as a numerical value in the finished shape management table, etc. There is a problem in that it is not possible to know the deviation amount information as a finished product even when looking at the corresponding finished product inspection photograph. In order to solve this problem, the deviation amount of the pile to be measured should be measured, the central deviation amount should be calculated, and the value should be entered on a blackboard or the like and copied into a part of the construction photograph. However, in this case, it is necessary to measure the component deviation amount, perform a simple calculation, transfer the calculated value to the blackboard, and take a picture in parallel. It is extremely inefficient work since it requires the use of workers, etc. to measure and photograph.

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, to enable a small number of people to easily measure the deviation amount of a pile, and to confirm the measured deviation amount in a construction photograph. It is to provide a ruler for measuring the deviation amount of a structure position that can be imprinted.

[0005]

In order to achieve the above object, the present invention is directed to an orthogonal reference line having an orthogonal origin substantially at the center position of a ruler plate surface and a concentric circle having a predetermined interval with the orthogonal origin as a central point. A structure outer shape line having a shape, a plurality of orthogonal scale lines parallel to the orthogonal reference line, a light-transmitting plate drawn on the ruler plate surface, the orthogonal reference line with the structure outer line as a guide. Set on the upper surface of the structure while keeping parallel to the structure reference core line, and directly read the deviation amount between the orthogonal origin and the surveying thread stretched above the structure reference core line on the ruler plate surface. It is characterized by doing so.

Further, the orthogonal reference line having an origin substantially at the center position of the ruler plate surface having an outer shape following the outer shape of the structure and a plurality of orthogonal scale lines parallel to the orthogonal reference line are described above. Set the ruler plate drawn on the surface of the ruler plate on the upper surface of the structure with the orthogonal reference line and the structure reference core line parallel to each other, and stretch it above the orthogonal origin and above the structure reference core line. The deviation amount from the surveying yarn is directly read on the surface of the ruler plate.

Further, on the surface of a ruler plate having an inscribed edge shape imitating the outer shape of the structure and capable of being divided into a plurality of parts as a whole, the inner inscribed edge is imitated by the outer shape of the structure. An orthogonal reference line that is orthogonal to the center position of the structure when the ruler plate is set and a scale line parallel to the orthogonal reference line are drawn, and the deviation between the orthogonal reference line and the structure reference core line is drawn. The feature is that the quantity is read directly.

It is preferable that the ruler plate is provided with, at a part of a side edge thereof, at least one bubble tube arranged so that one of the orthogonal reference lines becomes a horizontal axis.

When the bubble tube is provided, the ruler plate is set on the end surface of the tubular structure laid on the foundation so that one of the orthogonal reference lines becomes a horizontal axis and forms a substantially vertical plane. Then, it is preferable that the ruler plate is collimated by a surveying instrument and the deviation amount between the orthogonal reference line and the tubular structure center position is directly read.

Further, a light-transmissive direct ruler having a straight scale with the orthogonal origin of the orthogonal reference line formed on the ruler plate as the center of rotation and having the orthogonal origin as the scale origin is attached to the ruler plate. However, it is preferable to directly read the deviation amount between the orthogonal origin and the surveying thread stretched above the structure reference core line by the direct scale of the light transmissive direct ruler.

[0011]

According to the present invention, an orthogonal reference line whose origin is substantially the center of the surface of a ruler plate made of a light-transmissive plate, and a structure having a concentric shape with a predetermined distance from the origin of the orthogonal origin. An outline and a plurality of orthogonal graduation lines parallel to the orthogonal reference line are drawn on the ruler plate surface, and the parallel to the orthogonal reference line and the structure reference core line is maintained with the structure outline as a guide. By setting it on the upper surface of the structure and allowing the deviation amount between the orthogonal origin and the surveying thread stretched above the structure reference core line to be directly read on the ruler plate surface,
Since the position of the structure having various outer dimensions can be easily aligned through the light-transmitting plate, the center position of the target structure can be easily determined in any case. The structure deviation amount can be easily obtained by directly reading the distance from the object reference core line.

Further, an orthogonal reference line having an origin substantially at the center position of a ruler plate surface having an outer shape following the outer shape of the structure and a plurality of orthogonal scale lines parallel to the orthogonal reference line are described above. Set the ruler plate drawn on the surface of the ruler plate on the upper surface of the structure with the orthogonal reference line and the structure reference core line parallel to each other, and stretch it above the orthogonal origin and above the structure reference core line. By directly reading the deviation amount from the surveying yarn on the surface of the ruler plate, the center position of the structure of the target dimension can be easily determined, and the distance between the center position and the structure reference core line is directly read. Therefore, the amount of structural deviation can be easily obtained.

Further, on the surface of a ruler plate having an inscribed edge shape imitating the outer shape of the structure and capable of being divided into a plurality of parts as a whole, the inner contact edge is imitated by the outer shape of the structure. An orthogonal reference line that is orthogonal to the center position of the structure when the ruler plate is set and a scale line parallel to the orthogonal reference line are drawn, and the deviation between the orthogonal reference line and the structure reference core line is drawn. The orthogonal reference line set so as to pass through the structure center determined from the outer shape of the structure even in the case where the center position cannot be directly obtained by directly reading the amount. By reading the distance from the structure reference core line, the component deviation amount of the structure can be easily obtained.

By attaching the ruler plate to a part of the side edge, at least one bubble tube arranged so that one of the orthogonal reference lines becomes the horizontal axis is detachably attached, The deviation amount measuring ruler can be applied even when the upper surface of the structure constitutes a vertical plane.

When the bubble tube is provided, the ruler plate is set on the end surface of the tubular structure laid on the foundation so that one of the orthogonal reference lines becomes a horizontal axis and forms a substantially vertical plane. Then, the ruler plate is collimated by a surveying instrument, and the deviation amount between the orthogonal reference line and the tubular structure center position can be directly read.

Further, a light-transmissive direct ruler having a straight scale with the orthogonal origin of the orthogonal reference line formed on the ruler plate as the center of rotation and having the orthogonal origin as the scale origin is attached to the ruler plate. However, the displacement amount can be easily measured by directly reading the deviation amount between the orthogonal origin and the surveying thread stretched above the structure reference core line by the direct scale of the light-transmissive direct ruler. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the ruler for measuring the deviation amount of a structure according to the present invention will be described below with reference to FIGS. Figure 1
FIG. 4 is an explanatory diagram showing a state in which a deviation amount measuring ruler 10 is set on the pile head of a steel pipe pile P having a pile diameter (φ300 mm as an example) as a structure whose deviation amount is to be measured. As shown in the figure, the pile head of the steel pipe pile P is made of leveled concrete 50.
Of the deviation amount measuring ruler 10 is placed at the top end position of the pile. This deviation amount measuring ruler 10 is made of a transparent resin plate having a square shape, and its surface is centered on the intersection of the reference cross lines 11 and 12 and the reference cross lines 11 and 12 which are orthogonal reference axes as shown in FIG. A large number of concentric circles 13 as points, and grid graduation lines 14, 15 with the reference cross line as the X-axis and the Y-axis with the center point as the origin are drawn. In the present embodiment, each of these lines is drawn by printing, but fine groove lines may be engraved and the fine groove lines may be colored. At this time, the direction of deviation from the reference position of the pile can be identified at a glance by changing the used color for each quadrant. When the deviation amount measuring ruler 10 is used for collimating the degree of positional deviation of the installation center point of a tubular structure such as a sewer pipe laid in the trench, the reference cross line X-axis 11 can be used as the horizontal axis. Thus, the bubble tube 16 is provided at the plate end surface position.

Here, the deviation amount measuring ruler 10 shown in FIG.
The installation method and the usage method thereof will be described with reference to FIGS. 1 and 3. As shown in FIG. 3, water threads 61 are provided at predetermined intervals in the vertical and horizontal directions so that the reference core position of the pile can be confirmed as an intersection from the tension 60 installed around the pile foundation on which the leveling concrete 50 has been constructed. Stretch 62. Further, the deviation amount measuring ruler 10 is placed on the pile P. At this time, the deviation amount measuring ruler 10 is a transparent plate, and the reference cross lines 11 and 1
Since a concentric circle is drawn with the intersection of 2 as the center, the deviation amount measuring ruler 10 is adjusted according to the pile outer diameter while confirming the position of the pile P having a circular cross section through this concentric circle as a ruler.
The reference cross wires 11 and 12 and the reference core wires 63 and 64 are installed on the pile head so that they are parallel to each other. At the same time, centering of the pile center can be performed. Further, as shown in FIG. 1, the hanging thread 65 is fitted to the intersection of the water threads 61 and 62 stretched above the deviation amount measuring ruler 10 (upper point of the pile reference position), and the plumb bob 66 is moved to the deviation amount measuring ruler. It is possible to determine the component deviation amounts ΔX and ΔY (see FIG. 9) of the pile P that has been hung up to 10 and directly read the grid scales 14 and 15 (see FIG. 2) pointed by the swinging tip 66a.

Further, a light-transmissive transparent resin straight ruler 17 as shown in FIG. 8 is rotatably attached to the deviation amount measuring ruler 10 so that the straight ruler origin 17a coincides with the reference axis origin. Then, lower the transparent resin straightedge 17 and swing the tip 66a.
(Refer to Fig. 1) Positioning is performed so as to connect with, and the center deviation amount can be directly obtained by directly reading the scale 18 of the transparent resin straightedge 17 and the value can be immediately measured on a blackboard for inspection. You can fill it out. It is needless to say that the deviation amount on the deviation amount measuring ruler 10 can be measured in the same manner by using an ordinary straight ruler. If a construction photo is taken in any state, each deviation amount can be directly read from the construction photo. Therefore, it is also possible to directly create a workmanship management table from a workmanship photograph after construction. When piles are constructed in a wide range, as shown in Fig. 3, the Transit T is installed on the pile street and the deviation amount of each pile is calculated by X for each pile row.
The deviation amount data can be efficiently collected by measuring the direction and the Y direction at once.

FIG. 4 is an explanatory view showing an example in which a deviation amount measuring ruler 10 is used to measure a pipe installation error or the like in laying a buried sewer pipe. Trench 21 as shown
A deviation amount measuring ruler 10 is attached to an end surface of a reinforced concrete pipe 20 laid inside. The deviation amount measuring ruler 10 has a bubble tube 16 positioned on the upper side edge, and the bubble tube 16 allows the reference cross lines 11 and 12 to be attached so as to indicate horizontal lines and vertical lines. In this state, the laser sight L is installed with reference to the base point position of the existing manhole or the like and the center pile. At this time, the laser sighting device L is installed so that the design pipe center gradient (pipe laying gradient in the longitudinal direction) of the sewer pipe and the optical axis of the laser oscillation light B coincide with each other. By thus collimating the deviation amount measuring ruler 10 with the laser sighting device L, the spot position S on the deviation amount measuring ruler 10 is read and the deviation amount from the pipe center position of the reinforced concrete pipe 20 installed is confirmed. be able to.

FIG. 5 shows a deviation amount measuring ruler 30 for measuring the deviation amount of a pile having a predetermined pile diameter. The deviation amount measuring ruler 30 is a circular plate having a diameter equal to the outer diameter of the pile P, as shown in FIG. Therefore, the deviation amount measuring ruler 30 is placed on the top of the pile, and the X-axis and Y-axis directions of the reference cross lines 31, 32 are set to the ground ink (reference core line).
By aligning in parallel with 63 and 64, a function equivalent to that of the deviation amount measuring ruler 30 shown in FIG. 1 is exerted. In FIG. 5, the known surveying pin 67 is vertically lowered from the intersection of the water threads 61 and 62 to index the reference core position. The deviation amount of the pile P can be immediately measured by reading the coordinates on the deviation amount measuring ruler 30 of the surveying pin. It is needless to say that there is no functional difference from the plumb bob in FIG. 1, and various methods can be adopted based on a known surveying operation.

FIGS. 6 and 7 show a deviation amount measuring ruler 40 which is effective when the center position of the cross section of the target structure cannot be obtained. Deviation amount measuring ruler 40 having an inscribed edge shape that follows the outer shape of a structure with the pile P as an example
From the outside of the structure, and the distance from the ground ink (reference core line) on the leveling concrete near the structure to the center indicator line as the orthogonal reference lines 41 and 42 of the deviation amount measuring ruler 40 (component deviation amount). ΔX, ΔY) is measured for each of the X axis and the Y axis, and the amount of deviation from the reference position of the structure is measured. The deviation amount measuring ruler 40 is made of a ring-shaped plate material whose inner diameter (ring inner diameter) is substantially equal to the outer diameter of the pile P and which can surround the outer circumference of the pile P, as shown in FIG. A hinge 45 is formed at one end of the half-divided ruler plate, and the pile P is sandwiched and set as shown in FIG. And the stopper 46
The other end is locked to form a ring-shaped deviation amount measuring ruler 40 at the outer peripheral position of the pile P. Alternatively, a permanent magnet having a predetermined magnetic pole may be incorporated in the end surface of the ruler plate, and the ends of the ruler plate having a half-divided shape may be attracted by a magnetic force to form a ring shape. At this time, the deviation amount measuring ruler 40
When set in the state shown in FIG. 2B, the center indicating lines 41 and 42 located at orthogonal positions are further distributed to the both sides from the center indicating lines 41 and 42 in a predetermined dimension scale line 4 when set in the state of FIG.
3, 44 are drawn. By measuring the distance between the center indicating lines 41 and 42 and the ground ink (reference core lines) 63 and 64, the component deviation amounts ΔX and ΔY between the pile core and the reference core can be directly read and obtained. In this way, various cross-sectional shapes when the center position of the structure cannot be directly obtained include, for example, a temporary earth retaining pile P using a H-shaped steel as shown in FIG. 7 and a rectangular cross-section column. Even in this case, if the deviation amount measuring ruler 40 is used, the deviation amount between the center of various structures and the reference core line can be easily obtained.

Further, the deviation amount measuring ruler 10 shown in FIG.
Since a light-transmitting property was used, a transparent resin plate was used, but the deviation amount measuring ruler 3 shown in FIGS. 5, 6, and 7 was used.
0, 40 can be made of various materials such as resin, plywood, and metal such as aluminum, and it is also preferable to have a two-fold structure with a hinge or the like for convenience of transportation. Note that FIG.
The grid and concentric circle scales shown in are added for explanation, and the dimensions that match the size of various deviation amount measuring rulers,
It goes without saying that it is preferable to set the accuracy scale.
