DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-3This application is described in further detail.

[0023] The present application embodiment discloses a building measurement and setting out auxiliary fixed-point device. Figure 1-3 A construction surveying and setting out auxiliary fixed-point device comprises a base 5, the base 5 comprises a sleeve 501, a nail holding assembly 6 is installed on the inner side of the sleeve 501, the nail holding assembly 6 comprises a connecting tube 602 fixedly installed on the sleeve 501, a leveling nail 7 is installed in the connecting tube 602, a hollow telescopic rod 4 is installed on the upper end of the sleeve 501, a support frame 2 is fixedly installed on the upper end of the hollow telescopic rod 4, the support frame 2 comprises a bracket 201 fixedly installed on the hollow telescopic rod 4, a connecting piece is hinged at the upper end of the bracket 201, a prism 1 is installed on the connecting piece, an embedded nail assembly 3 is installed inside the hollow telescopic rod 4, the embedded nail assembly 3 comprises a pressure rod 301 movably installed inside the hollow telescopic rod 4, the pressure rod 301 can move along the Z axis and is coaxial with the leveling nail 7;

[0024] By adopting the above technical solution, using the prism 1 hinged to the bracket 201 through a connecting piece, after the layout point is determined, the position of the prism 1 relative to the bracket 201 can be adjusted so that there is no obstruction above the pressure rod 301, and then the pressure plate 303 is pressed down to move the pressure rod 301 downward to push the leveling nail 7, and the leveling nail 7 is pushed out of the connecting tube 602 to preliminarily embed the layout point, without lifting the prism and the centering rod, and then burying the leveling nail.

[0025] Reference Figure 2 The connecting member includes a connecting seat 202 hinged on the bracket 201, and a rotating shaft 203 is rotatably installed on the connecting seat 202. The end of the rotating shaft 203 is connected to the prism 1. The bracket 201 is symmetrically provided with two connecting holes with the hinge point as the center. A positioning hole is provided on the connecting seat 202, and a pin 204 is installed in the positioning hole. The positioning is performed by the pin 204 to improve the accuracy of the flip adjustment. The pin 204 slides through the corresponding connecting hole. The bracket 201 and the connecting seat 202 are hinged to realize that the prism 1 can be flipped left and right relative to the bracket 201 to avoid affecting the push-down operation of the pressure rod 301. At the same time, it can also rotate around the axis of the rotating shaft 203 to adjust the angle.

[0026] Reference Figure 2 The hollow telescopic rod 4 includes a plurality of sleeves that are connected to each other. Damping is installed on the inner sides of two adjacent sleeves to increase friction and achieve stopping at any position. A guide sleeve 302 is fixed on the pressure rod 301. The guide sleeve 302 is slidably connected to the inner wall of the innermost sleeve. The upper end of the pressure rod 301 slides through the bracket 201 and is connected to a pressure plate 303. The guide sleeve 302 and the sleeve are used for guidance to prevent the pressure rod 301 from deflecting when it moves downward.

[0027] Reference Figure 3, foot pedals 502 are installed on both sides of the sleeve 501 to facilitate the staff to step on them and prevent the pressure rod 301 from deflecting when it is pressed down. An elastic element is also provided between the connecting tube 602 and the pressure nail piece 603 in the sleeve 501. The pressure nail piece 603 includes a push rod 6031 slidably installed in the connecting tube 602. A guide ring 6032 is also sleeved on the upper end of the push rod 6031. The elastic element is a spring 601. The spring 601 is slidably sleeved on the spring 601 and is located between the guide ring 6032 and the connecting tube 602. The push rod 6031, the connecting tube 602, and the pressure rod 301 are on the same axis. A damping is installed on the inner side of the connecting tube 602 to increase the friction with the level nail 7 and prevent the level nail 7 from sliding off under the action of gravity.

[0028] The implementation principle of the auxiliary fixed-point device for building measurement and layout in the embodiment of the present application is as follows: the device is transported to the vicinity of the measurement point, and the base 5 is placed steadily on the ground. The hollow telescopic rod 4 is unfolded and adjusted to a suitable height. The prism 1 is rotated to the top of the pressure rod 301, and is initially fixed by the pin 204. By adjusting the angle and position of the prism 1, it is ensured that there is no obstruction above the prism, and the surveying instrument is used to perform preliminary positioning of the layout point, according to the positioning result. The staff steps on the pedals 502 on both sides of the base to ensure that the device is stable. Then remove the pin 204, turn the prism 1 to the other side, press down the pressure plate 303 or tap it with a hammer, so that the pressure rod 301 slides along the inside of the hollow telescopic rod 4, and pushes the pressure nail piece 603 to extend outward. The leveling nail 7 moves out of the connecting tube 602 under the push of the pressure nail piece 603, and the preliminary embedding of the layout point is completed. Release the pressure plate 303, and the pressure rod 301 is reset under the action of the elastic element 601, but the leveling nail 7 remains in the embedded position. The level nail 7 is finally fixed, such as by tapping with a hammer.
