Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The invention discloses a monitoring method of a cast-in-place support, which is characterized in that a laser emitter 5 is arranged on a pier stud 9 at one end of a support 8, a laser receiver 6 is arranged on the pier stud 9 at the other end of the support 8, and the laser receiver 5 is connected with an audible and visual alarm; a group of adjustable shutters 7 are arranged on a laser beam path between the laser transmitter 5 and the laser receiver 6, and the shutters 7 are connected with a bracket 8; when the support 8 is deformed and subsides beyond a safe range, the path of the laser beam is blocked by the light chopper 7, so that the laser receiver 6 is out of support and the light signal is deactivated, and an alarm is given. The laser transmitter 5 and the laser receiver 6 are mounted close to the side of the column of the carriage 8, ensuring that the path of the laser beam is within the adjustment range of the shutter 7. The light chopper 7 is fixed on the vertical rod of the bracket 7 through the hoop 4, and the position of the hoop 4 on the vertical rod of the bracket 7 is adjusted to adjust the up-down position of the light screen 1. The hoop 4 is connected with the shading plate 1 through a telescopic rod 3; the left and right positions of the light screen 1 are adjusted through the telescopic rod 3 connected with the hoop 4, so that laser beams pass through the U-shaped notch 2 on the light screen. When the light shielding plates 1 are adjusted, the light shielding plates 1 are sequentially adjusted backwards from one end of the group of light shielding plates 1 closest to the laser emitter 5; firstly, the black gummed paper is pasted at the U-shaped gap 2, the position of the U-shaped gap 2 through which the laser beam passes is determined by the light spot 10 irradiated on the black gummed paper by the laser beam, one light shielding plate 1 is adjusted, and one black gummed paper is torn off until all the light shielding plates 1 are adjusted. The gap of the U-shaped gap 2 is downward, and the length of the U-shaped gap 2 is within a safe deformation range; when the light screen 1 is adjusted, the initial position A of the laser beam is at the central position of the lower part of the U-shaped notch 2; when the support 7 is in the safe deformation range, the laser beam moves upwards to the position B along the U-shaped notch 2, when the support 7 deforms to exceed the safe range, the laser beam moves to the position C shielded by the U-shaped notch 2, and the light shielding plate 1 blocks the audible and visual alarm to give an alarm. When the shading plate 1 is adjusted, the deflection deformation position is larger near the middle part of the support 7 and the initial position of the laser beam is closer to the notch position A of the U-shaped notch 2 according to the adjustment of the deformation condition of the support 7.
The light shield for monitoring the cast-in-place bracket used in the method of the invention is shown in figures 1 and 2, and comprises a light shielding plate 1; the shading plate 1 is provided with a U-shaped notch 2 with a downward notch; one side of the shading plate 1 is connected with a hoop 4 through a telescopic rod 3.
Examples
For example, as shown in fig. 1 and 2, a laser emitter 5 is arranged on one side of a pier stud 9, a laser receiver 6 is arranged on the pier stud 9 on the other corresponding side, and the laser receiver 6 is connected with an audible and visual alarm device, so that the laser receiver 6 is normal when receiving a laser signal during working, otherwise, the audible and visual alarm device generates an alarm signal. The light chopper 7 is arranged near the top of the vertical rod of the bracket 8, the hoop 4 on the light chopper 7 is connected with the vertical rod of the bracket 8, and the light chopper 7 is connected with the hoop 4 through the telescopic rod 3 so as to adjust the position. When the laser support is installed, the laser transmitter 5 and the laser receiver 6 are installed firstly, and a laser route is determined to ensure that laser passes through the edge of the support 8. Open laser emitter 5, follow laser emitter 5 and pass through route along laser and install light screen 1 one by one, can cover black paper on light screen 1 during the installation for confirm that laser passes through the position of regulation, tear black paper after the light screen 1 is fixed well in the installation, guarantee that laser passes through U-shaped breach 2. When the shading plate 1 is installed, the deformation condition of the bracket 8 is adjusted, and the initial position of the light spot 10 with larger deflection is close to the point A. Because support 8 is compressed during the construction, the light spot can remove to B, as long as support 8 does not take place to exceed predetermined deflection, laser receiver 6 can receive laser signal all the time, so can not take place the police dispatch newspaper, nevertheless if certain root member piece takes place great settlement or skew, laser can be sheltered from to light screen 1, just sends the police dispatch newspaper when laser receiver 6 can not receive the laser, reminds the operation personnel to stop the construction to the inspection consolidates the support. Thereby the cast-in-place construction operation is safer.
