Description

Technical Field

[0001] The present application relates to the technical field of building construction measurement, and in particular to an anti-interference floor elevation measurement device and a precise measurement method thereof. Background Art

[0002] During construction, control lines serve as reference lines to help construction workers control the size, elevation and position of components such as floor slabs, walls, columns and beams during the pouring of concrete, bricklaying, and installation of doors and windows. Construction workers can detect deviations in a timely manner and make necessary corrections to ensure the accuracy and consistency of the building structure.

[0003] In the prior art, the control line measurement method for each floor of a building is mainly carried out by using a laser line marker. A laser line marker is a tool that uses laser technology for measurement. It guides the laser beam emitted by the laser device into the telescope tube and makes it shoot out along the sighting axis, thereby achieving horizontal measurement. In elevation measurement, the laser line marker ensures that the laser beam is shot out horizontally, providing the user with an accurate horizontal line, thereby helping to perform precise measurement and marking.

[0004] When installing this type of laser marking instrument, it is usually set up on a floor slab (hereinafter defined as the measuring floor slab) to measure the elevation of components such as walls, columns and beams on the measuring floor slab; however, during the construction process, the movement of on-site personnel on the measuring floor slab and the vibration of construction machinery will be directly transmitted to the laser marking instrument, causing the laser marking instrument to shake to a certain extent, thereby reducing the accuracy of the measuring elevation, and even the measuring error exceeds the limit allowed by the specification, so further improvement is needed.

[0007] By adopting the above technical scheme, through the setting of the penetration rod, the penetration rod is used to penetrate the measuring floor. When the laser line marker is installed, the support frame is placed on the ground or the next floor of the measuring floor. After the penetration rod is penetrated through the measuring floor, it is extended to the measuring floor and connected and fixed to the laser line marker, so that the laser line marker can be placed on the measuring floor and measure the elevation of the target (wall, column, etc.) on the measuring floor; the setting of the penetration rod prevents the laser line marker from directly contacting the measuring floor, thereby reducing the shaking amplitude of the support frame caused by the walking of on-site personnel on the measuring floor or the operation of construction machinery, thereby keeping the laser line marker as still as possible, and improving the measurement accuracy of the laser line marker.

[0008] Optionally, the support seat is rotatably mounted with a rotating shaft, and the adjustment assembly includes an adjusting screw, a connecting rod and an adjusting piece.

[0017] By adopting the above technical scheme and setting the limiting member, when the laser line marker, the penetration rod and the support seat are connected to each other, the limiting member forces the central axis of the mounting tube to be perpendicular to the plate surface of the mounting seat (that is, the plate surface of the mounting seat is perpendicular to the penetration rod), so that the laser line marker on the mounting seat remains in a horizontal state to measure the elevation of the target; after the elevation measurement is completed, the penetration rod is removed from the support seat, and the limiting member is separated from the limiting effect on the mounting seat, and the plate surface of the mounting seat flips under the action of its own gravity, and the plate surface of the mounting seat can be rotated to be parallel to the central axis of the mounting tube to store the mounting seat, thereby reducing the space occupancy rate of the overall structure, and the penetration rod can drive the laser line marker to pass through the measuring floor to recover the penetration rod and the laser line marker, thereby greatly improving the convenience of disassembly of the overall structure.

By driving the rotating head to rotate, the rotating shaft is driven to rotate to adjust the height of the support seat. After the support seat is adjusted to the set height, the through rod is sleeved on the rotating shaft, so that the rotating shaft is inserted into the insertion groove and the rotating head is inserted into the anti-rotation groove. The limit column can limit the free rotation of the rotating shaft, reduce the possibility of free rotation of the rotating shaft, and cause the height of the support seat to change, thereby improving the stability of the overall structure.

Both ends of the limiting arc strip 71 are fixedly connected to the bottom wall of the mounting seat 6. The outer peripheral wall of the mounting tube 61 is provided with a rotation groove 612 for the limiting arc strip 71 to penetrate; the outer arc surface of the limiting arc strip 71 is provided with a limiting groove 711, and the penetration rod 2 is provided with a plug-in groove 22 for the rotation shaft 13 to be plugged in, and the two ends of the plug-in groove 22 respectively pass through the two ends of the penetration rod 2.

[0051] Reference Figure 8 , Fig. 9 The limiting rod 72 is slidably installed in the plug-in slot 22, and the two ends of the limiting rod 72 are extended along the length direction of the through-rod 2. When the rotating shaft 13 is plugged into the plug-in slot 22 (that is, the through-rod 2 is installed on the upper surface of the support seat 11), the rotating shaft 13 forces the upper end of the limiting rod 72 to be exposed in the plug-in slot 22 to be plugged into the limiting slot 711 of the limiting arc bar 71, and when the limiting rod 72 is inserted into the limiting slot 711 of the limiting arc bar 71, the central axis of the mounting tube 61 is perpendicular to the plate surface of the mounting seat 6.

[0052] It should be noted that, in the present embodiment, the limiting rod 72 comprises a plurality of second unit rod bodies (the plurality of second unit rod bodies are not specifically shown in the figure), the plurality of second unit rod bodies are arranged corresponding to the plurality of first unit rod bodies, and each second unit rod body is slidably installed in the corresponding first unit rod body so as to be able to slide along the length direction of the through-rod 2; two adjacent second unit rod bodies abut against each other to combine to form a limiting rod 72 of a certain length.

[0053] Reference Figure 8 , Fig. 9 The counterweight block 63 is embedded with a first magnet 631, and the outer peripheral wall of the mounting tube 61 is embedded with a second magnet 613. When the plate surface of the mounting seat 6 rotates to be parallel to the central axis of the mounting tube 61, the first magnet 631 and the second magnet 613 are magnetically attracted to each other.

[0054] Reference Fig.10 The lower end surface of the limiting rod 72 is provided with a rotation-stop groove 721, the shape of which is matched with the shape of the rotating head 131 of the rotating shaft 13. When the penetration rod 2 is sleeved on the rotating shaft 13, the rotating head 131 of the rotating shaft 13 matches and is inserted into the rotation support groove of the limiting rod 72.

[0055] Reference Fig.10 , Fig.11In this embodiment, the second mounting member 81 includes a snap-on column 812 and a snap-on ring 813. The snap-on column 812 is fixedly mounted on the upper surface of the support seat 11. A groove is provided on the bottom wall of the mounting plate 8. The snap-on ring 813 is fixedly mounted on the inner wall of the groove. The snap-on ring 813 is elastically arranged. An inlet and outlet are provided on the outer peripheral wall of the snap-on ring 813 for the snap-on column 812 to enter and exit. When the bottom wall of the mounting plate 8 abuts against the upper surface of the support seat 11 and the rotating shaft 13 is inserted into the insertion groove 22, the snap-on ring 813 is snap-on to the snap-on column 812. The side wall of the snap-on ring 813 located at the inlet and outlet is integrally formed with a guide block 814. The guide block 814 has a guide surface 815. The guide surface 815 is used for the snap-on column 812 to abut against, so as to guide the snap-on ring 813 to deform, thereby opening the inlet and outlet to facilitate the entry and exit of the snap-on column 812.

[0056] The implementation principle of Example 3 of the present application is as follows: after the laser marking instrument 3 is completed, the penetration rod 2 is removed from the support seat 11. At this time, the limiting rod 72 is separated from the rotating shaft 13 and falls under the action of its own gravity, so that the upper end of the limiting rod 72 is separated from the limiting groove 711 of the limiting arc bar 71, and the mounting seat 6 is flipped under the action of the counterweight block 63, so that the plate surface of the mounting seat 6 is rotated to be parallel to the central axis of the mounting tube 61, thereby reducing the space occupancy rate of the mounting seat 6, so that the operator can lower the penetration rod 2, and the laser marking instrument 3 can pass through the penetration groove 91 of the measuring floor 9, so as to facilitate the disassembly of the laser marking instrument 3, and the operator can disassemble and assemble the overall structure on the ground or the next floor of the measuring floor 9, which greatly improves the convenience of disassembly of the overall structure.
