Description

Technical Field

[0001] This utility model relates to the field of top plate positioning and marking technology, and in particular to a top plate positioning and marking device. Background Technology

[0002] Before installing the roof support and hanger, the fixed points of the support and hanger, i.e. the positions of the installation bolts, need to be marked. The conventional practice is to first mark the lines on the roof, and then the construction workers need to use a steel tape measure on the scaffold to measure the distance on the marked lines and mark the fixed points. This method requires measuring and marking personnel, as well as personnel to stabilize and move the scaffold, which is not only labor-intensive but also involves high-altitude operations and poses certain safety hazards.

[0003] How to solve the above problems is the research topic of this plan. Utility Model Content

[0004] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides a top plate positioning and marking device.

[0005] The technical solution includes a telescopic ruler, a marker slot 1, a marker slot 2, and a fastening screw;

[0006] The telescopic scale includes an outer rod and an inner rod that is slidably sleeved inside the outer rod. Both the inner rod and the outer rod have scale lines on their outer walls.

[0007] The outer rod has a threaded hole on its bottom outer wall, and the top of the fastening screw is a threaded rod, the threaded rod part of which is threaded to match the threaded hole on the outer rod;

[0008] The top of the fastening screw passes through the threaded hole and abuts against the outer wall of the inner rod.

[0009] The inner and outer rods of the telescopic ruler are connected by a sliding sleeve. The threaded hole at the bottom of the outer rod matches the threaded rod of the fastening screw, which can abut against the outer wall of the inner rod to fix the length of the telescopic ruler. Marker slot one and marker slot two are used to fix the markers. The distance between the markers is determined by adjusting the length of the telescopic ruler, and the positioning and drawing of lines is performed using the principle of a compass.

[0010] The bottom of the fastening screw is designed as a handheld end, and a rubber anti-slip sleeve is provided on the outer wall of the handheld end. The rubber anti-slip sleeve increases the friction between the hand and the handheld end, preventing slippage during operation. The middle part of the fastening screw is designed as a telescopic rod. The telescopic rod design increases the flexibility of the fastening screw, allowing its length to be adjusted according to actual needs, making it better adaptable to telescopic rulers of different lengths.

[0011] Both the first and second marker slots have openings that match the markers, and the markers are secured in the slots with wire or rope. This securing method ensures that the markers are stable in the slots and will not loosen during drawing. This marker securing method is simple and effective, and using wire or rope also makes it easy to replace the markers, making the operation convenient.

[0012] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: This device is mainly used to mark the positions of the bolts, the fixing points of the roof support brackets, before installation. Through the cooperation of a telescopic ruler and a marker pen slot, combined with a laser line projector, the positioning of the roof support points can be quickly achieved. Compared with traditional methods, it eliminates the need for multiple people to cooperate in measurement and scaffolding movement, greatly reducing labor input and saving time. The device is simple, can be fabricated on-site, and can be quickly put into use for roof positioning and marking, improving the overall construction progress. The operation process is simple; after determining the second point, repeated double-point positioning can begin, making it easy to master. Furthermore, it avoids construction workers performing high-altitude operations on scaffolding, reducing safety hazards and ensuring the personal safety of construction workers.

[0019] Example 1

[0020] See Figure 1 This utility model provides a top plate positioning and marking device, including a telescopic ruler, a marker pen slot 1, a marker pen slot 2, and a fastening screw 3;

[0021] The telescopic scale includes an outer rod 5 and an inner rod 4 that is slidably sleeved inside the outer rod 5. Both the inner rod 4 and the outer rod 5 have scale lines on their outer walls.

[0022] A threaded hole is provided on the bottom outer wall of the outer rod 5, and the top of the fastening screw 3 is set as a threaded rod 301, which is threaded to match the thread of the threaded hole on the outer rod 5.

[0023] The top of the fastening screw 3 passes through the threaded hole and abuts against the outer wall of the inner rod 4.

[0024] The bottom of the fastening screw 3 is set as a hand-held end 302, and a rubber anti-slip sleeve is provided on the outer wall of the hand-held end 302.

[0025] The middle part of the fastening screw 3 is set as a telescopic rod.

[0026] Both marker slot 1 and marker slot 2 have slots that match the markers, and the markers are fixed in the slots by wire or rope.

[0027] The specific method for using this device is as follows:

[0028] 1. Before use, first determine the bracket spacing, adjust the length of the outer rod 5 and inner rod 4, and after determining the length with the telescopic ruler, tighten and fix it firmly with the fastening screw 3;

[0029] 2. Place the two markers into marker slot 1 and marker slot 2 respectively, and fix them in the slots with wire or rope. Use the principle of compass to position and draw lines.

[0030] 3. In the construction area of ​​the roof slab, the positions of the rows of fixing points, i.e., the bolts, are determined using a laser line projector;

[0031] 4. When using the device, measure the distance on the ground to determine the first fixed point using a plumb bob, and place the laser line projector. Turn on and adjust the laser line projector. The intersection of the two vertical projection lines is the first fixed point. Place the tip of one of the markers of the device, with the determined spacing, on the first fixed point as the center to draw a circle. The intersection of this circle with the projection line projected on the top plate by the laser line projector is the second point. Then, draw a circle with the tip of the marker at the second point as the center to obtain the third point. Repeat this process. The two markers serve as fulcrums for each other, which can quickly complete the positioning and line laying.
