[0002] During the installation and construction of nuclear power units, most types of pipe mounting frames are in the form of embedded plates. The pipe mounting frames include brackets and square steel (square steel is square steel with equal length and width). Before installing the brackets, the square steel needs to be welded to the embedded plates. Before welding the square steel on the embedded plates, it is necessary to draw lines on the embedded plates reserved for civil engineering according to the specific engineering drawings to determine the specific installation position. When the on-site operation team performs the traditional bracket layout operation, they first draw a cross center line on the embedded plate according to the bracket positioning given in the drawings.

[0003] The traditional way to determine the welding position of square steel on the embedded plate is to use the cross center line as the reference, and use a level and a protractor to draw a schematic wireframe of the bracket welding shape and the area that needs to be polished.

[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1As shown, an embodiment of the utility model provides a bracket embedded plate marking and positioning tool, comprising: a plate body 10, a positioning hole 101 for positioning is opened on the plate body 10, and the positioning hole 101 has at least a first hole wall and a second hole wall perpendicular to each other;

[0024] At least one zigzag hole 103 is formed on the plate body 10, and each two adjacent hole walls in the zigzag hole 103 are perpendicular to each other, and the two parallel hole walls are parallel to the first hole wall. The center point of the zigzag hole 103 is located on the connecting line where the plane where the first hole wall is located and the plane where the second hole wall is located intersect.

[0025] Specifically, the two lines of the cross center line of the first hole wall and the second hole wall of the positioning hole 101 are aligned to determine the position of the plate body 10 on the embedded plate. After the determination is completed, a schematic wireframe of the square steel is directly drawn in the circular hole 103, which simplifies the marking process, saves time and effort, and improves work efficiency. Workers can choose to grind on the embedded plate according to the position of the schematic wireframe to facilitate the subsequent welding of the square steel and the embedded plate.

[0026] According to an embodiment of the present invention, a plurality of meandering holes 103 are provided, and the center points of the plurality of meandering holes 103 coincide with each other.

[0027] A plurality of circular holes 103 are provided, which can correspond to a plurality of square steels of different specifications, and thus can position brackets of different specifications, so that the scope of use is wider and the practicability is stronger.

[0028] Furthermore, the length directions of the circular holes 103 of different specifications are the same, and several groups of circular holes 103 can be opened in the limited space of the plate body 10, so that the positioning tool can be applicable to square steels of more specifications.

[0029] It should be noted that each of the zigzag holes 103 corresponds to a square steel of a certain size, and the length and width of the zigzag hole 103 are the same as the length and width of the square steel of the corresponding size.

[0030] Of course, in this embodiment, if the length directions of the plurality of serpentine holes 103 are different, the positioning hole 101 is formed by a plurality of L-shaped holes (the two hole walls of the L-shaped hole are perpendicular to each other, and each L-shaped hole corresponds to a serpentine hole 103, that is, one of the side walls of the L-shaped hole is parallel to the length direction of the serpentine hole 103), and then the position of each corresponding serpentine hole 103 can be confirmed according to the L-shaped hole. Its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.

[0031] Of course, the positioning hole 101 can also be a regular cross-shaped hole, and the intersection of the regular cross-shaped hole is aligned with the intersection of the cross center line, so as to determine the position of the center point of the plate body 10 on the embedded plate.

[0032] Furthermore, the two sides of the cross-shaped hole corresponding to the square steel specification are aligned with the two lines of the center cross line, and then the exact position of the plate body 10 on the embedded plate is determined, and the corresponding line is drawn in the round hole 103.

[0033] Furthermore, a connecting line where the plane where the first hole wall is located and the plane where the second hole wall is located intersect is recorded as a positioning line.

[0034] According to an embodiment of the present invention, the serpentine hole 103 is composed of two L-shaped holes, and the two L-shaped holes are not connected.

[0035] Specifically, the circular hole 103 is composed of two L-shaped holes. The two L-shaped holes are not connected to prevent the plate body 10 from being split into multiple plates, thereby reducing the processing difficulty of the plate body 10. The two L-shaped holes are symmetrical in center, and their center points are located on the positioning line.

[0036] It should be noted that the L-shaped hole is composed of two mutually perpendicular and connected first strip holes and second strip holes. The longer the first strip holes and the second strip holes are, the more complete the schematic wireframe of the square steel is, and the grinding range can be more precise.

[0037] According to an embodiment of the present invention, the zigzag hole 103 is composed of two concave holes, and the two concave holes are not connected.

[0038] Specifically, the circular hole 103 is composed of two concave holes, and the two concave holes are not connected to prevent the plate body 10 from being split into multiple plates, thereby reducing the difficulty of processing the plate body 10 .

[0039] Furthermore, both ends of the two concave holes are not connected, which enhances the strength of the plate body 10. Optionally, the two concave holes are recorded as a first scored hole and a second scored hole, wherein one end of the first scored hole is connected to one end of the second scored hole, and the other end of the first scored hole is not connected to the other end of the second scored hole. This design method enables the square steel schematic wireframe to be drawn directly without interruption, which is more convenient.

[0040] According to an embodiment of the present invention, the positioning hole 101 is a rectangular hole. The positioning hole 101 can be a rectangular hole. The connecting line where the first side wall and the second side wall of the rectangular hole intersect is the positioning line. This design has two alignment methods:

[0041] First method:

[0042] Step 1: First, align the intersection point of the connecting line where the first side wall and the second side wall intersect with the intersection point of the cross center line;

[0043] Step 2: align it with one of the cross center lines through the first side wall, or align it with the other line of the cross center line through the second side wall.

[0044] Second method:

[0045] Step 1: Align the first side wall with one of the center lines of the cross;

[0046] Step 2: Move the plate 10 and align it with another line of the cross center line through the second side wall.

[0047] Optionally, the positioning hole 101 is an L-shaped hole, and the connecting line where the first side wall and the second side wall of the L-shaped hole intersect is the positioning line, and the positioning method thereof is the same as that of the rectangular hole.

[0048] Specifically, the plate body 10 is a square plate, and the size of the square plate is the same as the specification of the square steel. Therefore, the plate body 10 itself can also be used for marking and positioning, and the position of the square steel on the embedded plate is determined by the position of the drawn square steel schematic wireframe.

[0049] Of course, in this embodiment, the plate body 10 can also be a circular plate, a polygonal plate, etc.

[0050] Furthermore, a size mark is engraved on the same side of each zigzag hole 103 .

[0051] According to an embodiment of the utility model, size marks are engraved on the same side of each serpentine hole 103, so that when square steels of different specifications are needed, the corresponding serpentine hole 103 can be quickly found and lines can be drawn inside the serpentine hole 103, thereby improving work efficiency.

[0052] Of course, in this embodiment, by attaching a specification label of the corresponding square steel on the same side of each zigzag hole 103, the zigzag holes 103 corresponding to square steels of different specifications can also be quickly found, thereby improving work efficiency. The purpose does not deviate from the design concept of the utility model, and therefore, should belong to the protection scope of the utility model.

[0053] As a specific embodiment, an auxiliary piece for hand-holding is installed on the board body 10. Installing the auxiliary piece for hand-holding on the board body 10 can facilitate quick taking of the board body 10.

[0054] The auxiliary part includes an extension plate 30, and a handle 20 is fixedly connected to the extension plate 30. The setting of the handle 20 can facilitate the worker to quickly take the next embedded plate to mark the line after marking the embedded plate, and because the handle 20 is set, it can be faster and more convenient to adjust the position of the plate body 10 on the embedded plate.

[0055] Handle 20 The small tube is bent into a semi-arc shape to fit the hand, one end of which is welded to the plate body 10 and the other end is welded to the extension plate 30 for easy picking up.

[0056] As a specific embodiment, a reinforcing plate 102 is fixedly connected to the plate body 10 .

[0057] The overall structure of the positioning tool is simple. The plate body 10 itself is a two-millimeter thick plate. Due to its thin thickness, the entire positioning tool is light and easy to carry without physical effort. However, due to its thin thickness and the multiple round holes 103 on the plate body 10, its strength is relatively low. Therefore, a reinforcing plate 102 is welded on the plate body 10 to strengthen the strength of the plate body 10 and make it less prone to damage.

[0058] The thickness of the reinforcing plate 102 is 1 mm to 3 mm. According to an embodiment of the present invention, the thickness of the reinforcing plate 102 is 1 mm.

[0059] Furthermore, the reinforcing plate 102 and the handle 20 are located on the same side of the plate body 10, so as not to interfere with the marking work. The welding position of the reinforcing plate 102 can just not block the round hole 103 (such as Figure 1 ), which is convenient for marking operation.

[0060] In this embodiment, the sizes of the plurality of serpentine holes 103 are 50*50, 60*60, 80*80, 100*100, 120*120, 140*140, and 160*160 (in millimeters).

[0061] The width of the zigzag hole 103 is determined according to the brush tip. A groove width of 3 mm is selected to facilitate marking 3 mm in the zigzag hole 103. When the plate body 10 is a square plate, the size of the plate body 10 is 180*180 (mm). In this embodiment, when the plate body 10 is a square plate, the positioning tool can meet the marking work of a 50-180 mm bracket on site. When the plate body 10 is a plate of other shapes, the positioning tool can meet the marking work of a 50-160 mm bracket. The positioning tool is light in weight and is easy to carry compared to traditional tooling.

[0062] Directions:

[0063] Step 1: align the first side wall and the second side wall of the positioning hole 101 with the two side walls of the cross center line respectively to determine the position of the plate body 10;

[0064] Step 2: Find the size mark of the corresponding square steel according to the size specification of the selected bracket, and use a marker to draw a line in the round hole 103 of the corresponding size mark.

[0065] Compared with the traditional marking mode, the use of this positioning tool can save 40″ of time and reduce investment by 50%, which can greatly improve the on-site marking speed, optimize the marking process, reduce labor intensity, and improve work efficiency.
