Description

Technical Field

[0001] This invention relates to the field of construction technology, specifically to a measuring instrument and method for nighttime auxiliary control of layered pouring height. Background Technology

[0002] With the development of the construction industry and the increasing sophistication of construction techniques, the demands for construction progress are becoming more urgent, often leading construction companies to carry out concrete work at night. Nighttime construction suffers from poor lighting conditions within the formwork, and the inconsistent lighting conditions under different working conditions make it impossible to determine the concrete pouring height, implement various concrete pouring measures, and even guarantee personnel safety. Although numerous studies and standards exist to ensure the safety of workers during nighttime construction, the quality of nighttime construction has not yet received widespread attention from construction workers.

[0003] Currently, the conventional solution to quality problems in nighttime construction is to have management personnel stand by and direct the work overnight. However, this approach alone leads to difficulties in personnel management, slows down construction progress, and increases project costs. Summary of the Invention

[0004] The purpose of this invention is to provide a measuring instrument for nighttime auxiliary control of the layered pouring height, including a housing, a light-transmitting plate, a lamp holder, a light strip, a light-blocking plate, and a transmission mechanism.

[0005] The outer shell is a cubic structure with a hollow interior, a closed bottom, and an open top, with the open side sealed by a cover plate. The four side walls of the outer shell are designated as side wall I, side wall II, side wall III, and side wall IV in a clockwise direction.

[0006] The outer casing has a through hole on its side I, which is arranged along the height direction of the outer casing and extends through the upper and lower ends of the outer casing.

[0007] A light-transmitting plate is installed at the location of the through hole.

[0008] A lamp holder is installed inside the housing. The lamp holder includes an upper crossbar, a lower crossbar, and two opposing vertical bars for connecting the upper and lower crossbars. The upper and lower crossbars can slide up and down along the vertical bars. The lower crossbar is located below the upper crossbar and near the closed end of the housing.

[0009] The upper and lower crossbars are equipped with light-blocking plates on their upper surfaces and light strips on their lower surfaces. The light strips include light strip I and light strip II. Light strip I is installed on the upper crossbar, and light strip II is installed on the lower crossbar. Light strip I and light strip II are different colors.

[0010] An electric push rod is fixed on the lower crossbar, with the telescopic end of the electric push rod facing the upper crossbar.

[0011] The transmission mechanism includes transmission mechanism I and transmission mechanism II.

[0012] The transmission mechanism I and transmission mechanism II are used to adjust the positions of the upper crossbar and the lower crossbar, respectively.

[0013] Furthermore, the transmission mechanism I includes a rotating shaft I, a gear I, a toothed conveyor belt I, a transmission gear I, a roller I, a guide rail, a screw I, and an external knob.

[0014] The rotating shaft I is located inside the cavity of the outer casing, with one end connected to an external knob fixed to the outer casing and the other end connected to gear I. Transmission gears I are mounted on the two ends of the upper crossbar facing sides II and IV. Transmission gear I and gear I mesh with toothed conveyor belt I, respectively.

[0015] The outer shell cavity has two guide rails facing each other, and two vertical rods are located between the two guide rails. The transmission gear I is connected to the roller I set in the guide rails through the screw I.

[0016] The transmission mechanism II includes a rotating shaft II, a gear II, a toothed conveyor belt II, a transmission gear II, a roller II, a guide rail, a screw II, and an inner knob.

[0017] The inner knob and the outer knob are coaxially arranged, the rotating shaft I is a hollow shaft, and the rotating shaft II is located inside the rotating shaft I.

[0018] The rotating shaft II is located inside the cavity of the outer casing, with one end connected to an inner knob fixed to the outer casing and the other end connected to gear II. Transmission gears II are mounted on the two end faces of the lower crossbar facing side II and side IV. The transmission gears II and gear II mesh with the toothed conveyor belt II, respectively.

[0019] The transmission gear II is connected to the roller II set in the guide rail via the screw II.

[0020] Furthermore, when the outer knob is rotated, gear I drives the transmission gear I on the upper crossbar to rotate through the toothed conveyor belt I, and roller I drives the upper crossbar to rise and fall vertically along the guide rail under the action of screw I.

[0021] When knob II is rotated, gear II drives the transmission gear II on the lower crossbar to rotate via toothed conveyor belt II, and roller II drives the lower crossbar to slide along the vertical bar under the action of screw II.

[0022] Furthermore, the outer shell is made of aluminum alloy.

[0023] Furthermore, the outer shell body includes two opposing side plates and a back plate vertically connected to the two side plates, forming a U-shaped cross-section groove with an open end.

[0024] The open edges of the two side plates are provided with Z-shaped connecting plates extending into the groove. The connecting plate includes two stepped surfaces and a transition surface perpendicular to the two stepped surfaces, and the stepped surfaces are arranged parallel to the back plate.

[0025] The light-transmitting panel is installed on a stepped surface away from the side panel and secured with screws.

[0026] Furthermore, a scale is provided on the inner wall of the light-transmitting plate to determine the distance between the upper and lower crossbars.

[0027] Furthermore, the light-transmitting plate and the cover plate are made of PVC board, and the cover plate is fixed to the outer shell by clips or screws.

[0028] Furthermore, the lamp holder is a plastic lamp holder.

[0029] Furthermore, the colors of the light strips I and II are one of the three colors: red, yellow, and blue.

[0030] Another objective of this invention is to provide a method for using a measuring instrument for nighttime-assisted control of layered pouring height, comprising the following steps:

[0031] 1) Install batteries in the LED strip and turn on the power to confirm that the LED strip is intact;

[0032] 2) Adjust the extension length of the electric push rod based on the determined layered pouring height;

[0033] 3) Place the device into the concrete wall that is being poured;

[0034] Turn on LED strip II and adjust the inner knob to lower the lower crossbar until LED strip II is just covered by the concrete and the light-blocking plate on the lower crossbar.

[0035] 4) Turn on LED strip I and adjust the outer knob so that the upper crossbar descends until the bottom surface just touches the end of the telescopic end of the electric push rod;

[0036] 5) Pour concrete until the light strip I is blocked by the concrete and the light-blocking plate on the upper crossbar, completing one layer of pouring;

[0037] 6) Remove the device from the concrete and move it to the next pouring area, repeating steps 3) to 5).

[0038] The technical effects of this invention are undeniable, and its beneficial effects are as follows:

[0039] 1. This device is easy to operate, has a simple structure, low cost, and its main components can be reused. It is safe, aesthetically pleasing, and easy to promote. It can greatly improve construction efficiency and save project costs. It is especially suitable for high shear wall structures that require layered pouring.

[0040] 2. This invention has low requirements for the operating environment and has its own light source. Even in the depths of the wall where external lights cannot reach, it can still clearly distinguish whether the pouring height has been reached, which is more accurate, ensures the implementation of construction measures, and effectively increases the pouring quality.
