TECHNICAL FIELD
[0001] The utility model belongs to the technical field of fabricated building, especially relates to a fabricated wall component laser positioning device. BACKGROUND
[0002] The fabricated wall component is a building part for constituting the wall of a building, which is prefabricated in a factory and transported to a construction site, and then hoisted to a designed position by hoisting equipment for installation. When the fabricated wall component falls on the designed installation position, each steel bar hole reserved at the bottom needs to be aligned with each steel bar embedded in the ground. The above process usually relies on the naked eye observation, judgment and command of the construction personnel, and visual deviation is easy to exist through naked eye observation, so that the fabricated wall component is not easy to quickly align in place. In addition, a positioning ruler can also be used to assist the fabricated wall component to align the installation position in the construction site. The positioning ruler with a size just the same as the length size of the fabricated wall component can position the two side faces of the fabricated wall component by using the two end faces, but there are often fabricated wall components with different length sizes in the walls constituting the building, so different sizes of positioning rulers need to be configured, which not only has high cost, but also needs to rely on the naked eye observation and judgment of the observation personnel to determine whether the side face of the fabricated wall component is aligned with the end face of the positioning ruler, and visual deviation and the problem that the fabricated wall component is not easy to quickly align in place are also easy to exist.

Embodiments
[0023] A prefabricated wall component laser positioning device, as shown in Figure 1 The main components are a laser level 1, a positioning base plate 2, a long ruler 3, a short ruler 4, a first positioner 5, and a second positioner 6.
[0024] As shown in Figure 1 The positioning base plate 2 is a long strip-shaped plate structure made of stainless steel, aluminum alloy or plastic.
[0025] As shown in Figure 1 and Figure 2 The long ruler 3 is fixed to the top surface of the positioning base plate 2 and extends along the length direction of the positioning base plate 2. The top surface of the long ruler 3 is provided with a plurality of scale lines indicating length, the adjacent scale lines have a spacing of 1mm, and the corresponding numerical identifiers are provided. The center of the top surface of the long ruler 3 is provided with a numerical identifier "0" indicating the starting point as zero. On both sides of the numerical identifier "0", from near to far, at the 10cm, 20cm, 30cm, etc. integer multiple scale lines from the "0" scale line, the numerical identifiers "10", "20", "30", etc. are provided, indicating the length unit number from the starting point. The structure of the above long ruler 3 is a conventional ruler structure, which will not be described here.
[0026] As shown in Figure 1 and Figure 2 The short ruler 4 is provided with two, both of which are fixedly arranged on the top surface of the positioning base plate 2 and extend along the length direction of the positioning base plate 2, and both of which are parallel to the long ruler 3. Based on the scale lines of the long ruler 3, the installation spacing between the two short rulers 4 on the positioning base plate 2 can be measured. The top surface of the short ruler 4 is also provided with a plurality of scale lines indicating length, the adjacent scale lines have a spacing of 1mm, and the corresponding numerical identifiers are provided at 1cm, 2cm, 3cm, etc. indicating the length unit number from the starting point. The structure of the above short ruler 4 is a conventional ruler structure, which will not be described here.
[0027] Specifically, as shown in Figure 2As shown, both ends of the short ruler 4 are fixedly provided with second positioning devices 6 for suspending the short ruler 4 on the top surface of the positioning base plate 2. The short ruler 4 is fixed on the positioning base plate 2 by the two second positioning devices 6, and a certain distance is made between the short ruler 4 and the positioning base plate 2.
[0028] like Figures 1 to 3 As shown, each short ruler 4 is equipped with a sliding first locator 5, and each first locator 5 is fixedly equipped with a laser level 1; the first locator 5 can slide and adjust its position on the short ruler 4, thereby adjusting the position of the laser level 1, and can further adjust the distance between the two laser levels 1 within a certain range based on the length of the short ruler 4, so as to adapt to the installation and positioning requirements of prefabricated wall components of different lengths and sizes.
[0029] Specifically, such as Figure 4 and Figure 5 As shown, the first locator 5 includes a positioning slider 5.1 and a locking bolt 5.2. The positioning slider 5.1 has a slot 5.3 through which a short ruler 4 can pass. Specifically, the slot 5.3 is T-shaped and passes through the bottom surface of the positioning slider 5.1. The side wall of the positioning slider 5.1 has an internal threaded hole that communicates with the slot 5.3. The locking bolt 5.2 is threaded into the internal threaded hole. Tightening the locking bolt 5.2 causes its inner end to abut against the short ruler 4 in the slot 5.3, which can fix the first locator 5 on the short ruler 4. After loosening the locking bolt 5.2, the positioning slider 5.1 can slide on the short ruler 4 to adjust its position, thereby adjusting the distance between the two laser levels 1.
[0030] like Figure 5 As shown, the structure of the second positioner 6 is the same as that of the first positioner 5, so that the short ruler 4 and the second positioner 6 can be detachably connected, which is convenient for disassembly and assembly; the bottom end of the second positioner 6 is welded or glued to the positioning base plate 2.
[0031] The short ruler 4 is a steel ruler with a certain degree of rigidity and is not easily bent, enabling it to support the weight of the first locator 5 and the laser level 1. The short ruler 4 can be an existing product, such as a steel ruler with a maximum measuring length of 20cm or 30cm. The two short rulers 4 are symmetrically arranged on the positioning base plate 2 with the number "0" as the center. The maximum number on each short ruler 4 is located at the end furthest from the center of the positioning base plate 2. The installation structure of the short ruler 4 makes it easier to measure the distance between the two laser levels 1 more intuitively. For example, for a prefabricated wall component with a length of 1m, the two laser levels 1 only need to be adjusted to the number "50" indicating a length of 50cm at the left and right ends of the long ruler 3, specifically, the beam emitted by the laser level 1 coincides with the scale line at the number "50" on the long ruler 3.
[0032] In a preferred embodiment, the long ruler 3 is a tape measure or a ruler, which is glued to the top surface of the positioning base plate 2.
[0033] Alternatively, the long ruler 3 can be integrally formed with the positioning substrate 2, and the top surface of the positioning substrate 2 can be printed with several equally spaced scale lines along the length direction to form the long ruler 3.
[0034] In this embodiment, the laser level 1 is an existing product, which is sold on online or offline shopping platforms, such as the ZhonNa small laser level with red cross and red vertical line. The first locator 5 and the second locator 6 are both sold on online shopping platforms, such as the BTE20MM locator, which is suitable for holding short rulers 4 with a width of 15~20mm. The long ruler 3 can be a 70-0-70cm center ruler.
[0035] The working principle of this embodiment is as follows:
[0036] When hoisting prefabricated wall components at a construction site, this laser positioning device is used to position the installation location of the prefabricated wall components. The position of the first locator 5 is adjusted by sliding on the short ruler 4, thereby adjusting the position of the laser level 1. Based on the length of the prefabricated wall components, the distance between the two laser levels 1 on the positioning base plate 2 is pre-adjusted with the scale line of the long ruler 3 as a reference. This distance represents the installation length of the prefabricated wall components.
[0037] like Figure 3 As shown, in this embodiment, two short rulers 4 are fixed on the positioning base plate 2, with their ends aligned with the 40cm and 60cm scale lines of the long ruler 3, respectively. The lengths occupied by the laser level 1, the first locator 5, and the second locator 6 on the short rulers 4 are 4cm, 2cm, and 2cm, respectively. The positioning beam emitted by the laser level 1 is located at its center. Therefore, the minimum distance between the two positioning beams emitted by the two laser levels 1 corresponds to the 44-0-44 scale line on the long ruler 3, which is 88cm, while the maximum distance corresponds to the 56-0-56 scale line on the long ruler 3, which is 112cm. Therefore, the fixed position of the two short rulers 4 on the positioning base plate 2 makes the laser positioning device suitable for installing prefabricated wall components with a positioning length range of 88~112cm.
[0038] When the fabricated wall component is installed on site, the positioning base plate 2 is laid on the ground in front of the installation position of the fabricated wall component, the two laser levels 1 are turned on to emit positioning light beams, and the positioning light beams of the two laser levels 1 are respectively aligned with the installation positions of the left and right end faces of the fabricated wall component. When the fabricated wall component is hoisted and installed, the two sides of the fabricated wall component are respectively aligned with the positioning light beams emitted by the two laser levels 1, and then the fabricated wall component is lowered, so that the fabricated wall component can be quickly positioned and placed in the specified installation position.
[0039] Based on fabricated wall components of different lengths, the positions of the laser levels 1 can be adjusted on the short ruler 4, so that the distance between the two laser levels 1 on the positioning base plate 2 is adjusted to adapt to the length of the fabricated wall component. The two positioning light beams emitted by the laser positioning device are used to position the two sides of the fabricated wall component, so that the fabricated wall component can be quickly aligned with the installation position. Embodiment

After the second positioners 6 at the two ends of the short ruler 4 are detached from the positioning base plate 2, the two second positioners 6 are fixedly installed at other positions on the positioning base plate 2, so that the position of the short ruler 4 on the positioning base plate 2 can be adjusted, and the distance between the two short rulers 4 on the positioning base plate 2 can be adjusted, which is suitable for the installation and positioning requirements of fabricated wall components of different lengths.
[0041] Specifically, in the embodiment, the bottom surface of each of the second positioners 6 is glued to the top surface of the positioning base plate 2 by double-sided tape, so that the second positioner 6 and the positioning base plate 2 can be detachably connected.
[0042] In addition, other detachable connection structures can also be used between the second positioner 6 and the positioning base plate 2. For example, a vacuum suction cup is arranged on the bottom surface of the second positioner 6, and the vacuum suction cup is fixedly attached to the top surface of the positioning base plate 2 by suction. Alternatively, a sliding groove extending along the length direction of the positioning base plate 2 is formed on the positioning base plate 2, the cross section of the sliding groove is inverted T-shaped, a bolt is arranged in the sliding groove, the head of the bolt can be embedded in the sliding groove, the bolt penetrates through the second positioner 6 and is provided with a nut, after the nut is tightened, the nut and the head of the bolt clamp and fix the second positioner 6 and the positioning base plate 2 together, and after the nut is loosened, the second positioner 6 can be slid along the sliding groove to adjust the distance between the two short rulers 3.
