Description

Technical Field

[0001] The utility model relates to the technical field of wire laying and positioning, in particular to a wire laying and positioning device for a buckling-restrained brace embedded part. Background Art

[0002] In construction projects, the buckling-restrained brace technology is an important part used to improve the seismic resistance in building structures. The buckling-restrained brace can not only bear and transfer loads, but also provide additional energy dissipation capacity during an earthquake, thereby protecting the main structure from serious damage. The accurate wire laying and positioning of the buckling-restrained brace embedded part is crucial for ensuring the safety and stability of the structure. The existing wire laying and positioning methods usually rely on manual measurement and marking using tools such as theodolites and total stations.

[0003] However, practice shows that the existing wire laying and positioning methods for buckling-restrained brace embedded parts have the following problems: Tools such as theodolites and total stations require professional technicians to operate and involve complex measurement steps to ensure the accurate position of the embedded part in the vertical direction. The whole process takes a long time, reducing the construction efficiency.

[0004] Therefore, it is necessary to invent a wire laying and positioning device for a buckling-restrained brace embedded part to solve the above problems. Content of the Utility Model

[0005] The utility model provides a wire laying and positioning device for a buckling-restrained brace embedded part to solve the problem of low construction efficiency caused by complex measurement steps and long time consumption in the existing wire laying and positioning method for buckling-restrained brace embedded parts.

[0006] The utility model is implemented by adopting the following technical scheme:

[0007] A wire laying and positioning device for a buckling-restrained brace embedded part includes a telescopic cross bar. Two plumb bobs are suspended on the telescopic cross bar and are distributed left and right. The central axes of the two plumb bobs and the central axis of the telescopic cross bar are all on the same vertical plane. A laser is installed at the bottom end of each plumb bob.

[0008] Further, a vertically penetrating chute is opened on the telescopic cross bar. A slider is tied to the top end of the vertical line of each plumb bob, and the slider is slidably connected to the chute.

[0009] Further, the telescopic cross bar includes an outer tube. Inner tubes are inserted at both ends of the outer tube. Fixing holes are opened on the outer surfaces at both ends of the outer tube. A nut is threadedly connected to each fixing hole, and the tail end of each nut abuts against the outer surface of the corresponding inner tube.

[0010] Further, scale lines are engraved on the telescopic cross bar.

[0011] Furthermore, mounting plates are fixed to the tops of both ends of the telescopic cross bar, and mounting holes are formed in each mounting plate.

[0012] Furthermore, the telescopic cross bar is made of a square tube.

[0013] The structure of the utility model is reasonably and reliably designed. Two points can be determined by the light rays emitted by two lasers, and according to the principle that two points determine a straight line, the straight line where the embedded position of the buckling restraint brace embedded part is located can be quickly determined, or the embedded position of the embedded part can be directly determined by the light rays emitted by the laser, improving the accuracy and efficiency of positioning, solving the problem that complex measurement steps are required in the traditional method to determine the setting-out position of the buckling restraint brace embedded part, simplifying the setting-out and positioning process, effectively improving the construction efficiency, and ensuring the position accuracy of the embedded part; at the same time, the adjustable length of the telescopic cross bar and the mobility of the plumb bob enhance the adaptability of the device and are applicable to different construction environments; furthermore, it has the advantage of being easy to operate.

[0017] A setting-out and positioning device for a buckling restraint brace embedded part, as shown in Attach Figure 1 ~Attach Figure 2 shown, includes a telescopic cross bar. Two plumb bobs 1 distributed left and right are suspended on the telescopic cross bar, and the central axes of the two plumb bobs 1 and the central axis of the telescopic cross bar are all on the same vertical plane. A laser 2 is installed at the bottom end of each plumb bob 1.

[0018] In the utility model, the telescopic cross bar is used to support the two plumb bobs 1 to ensure that the light rays emitted by the laser 2 are vertically downward. The central axes of the plumb bobs 1 and the central axis of the telescopic cross bar are all on the same vertical plane to ensure that the laser 2 provides an accurate positioning reference. Two points can be determined by the light rays emitted by the two lasers 2, and according to the principle that two points determine a straight line, the straight line where the embedded position of the buckling restraint brace embedded part is located can be quickly determined, or the embedded position of the embedded part can be directly determined by the light rays emitted by the laser 2, improving the accuracy and efficiency of positioning, solving the problem that complex measurement steps are required in the traditional method to determine the position of the buckling restraint brace embedded part, and simplifying the setting-out and positioning process.

[0019] A sliding groove 3 that penetrates up and down is provided on the telescopic cross bar. A slider 4 is tied to the top end of the vertical line of each plumb bob 1, and the slider 4 is slidably connected to the sliding groove 3.

[0020] The structural design of the sliding groove 3 allows the slider 4 on the plumb bob 1 to slide on the telescopic cross bar, enabling the plumb bob 1 to adjust its position as needed, increasing the flexibility of the device, and allowing the position of the plumb bob 1 to be adjusted according to actual requirements, thus adapting to different construction scenarios.

[0021] The telescopic cross bar includes an outer tube 5. Inner tubes 6 are inserted at both ends of the outer tube 5. Fixed holes are provided on the outer surfaces at both ends of the outer tube 5. A nut 7 is threadedly connected to each fixed hole, and the tail end of each nut 7 abuts against the outer surface of the corresponding inner tube 6.

[0022] By adjusting the relative positions of the outer tube 5 and the inner tube 6, the length of the telescopic cross bar can be changed to meet actual needs, improving the adaptability of the device. At the same time, it is also convenient for transportation and storage; the nut 7 is used to lock the length of the telescopic cross bar.

[0023] Scale lines are engraved on the telescopic cross bar.

[0024] The structural design of the scale lines facilitates reading the actual length of the telescopic cross bar, thereby accurately adjusting the length of the telescopic cross bar or positioning the plumb bob 1 to ensure the accuracy of wire laying and positioning.

[0025] Mounting plates 8 are fixed to the top of both ends of the telescopic cross bar. Mounting holes are provided on each mounting plate 8.

[0026] The structural design of the mounting plate 8 is used to fix the device to the support structure at the construction site, thereby ensuring the stability and reliability of the entire device during use and preventing it from being easily displaced.

[0027] The telescopic cross bar is made of a square tube.

[0028] The following further elaborates on the present utility model through specific embodiments. It should be noted that the present utility model is not limited to the following embodiments. Embodiment 1

[0029] In this embodiment, a rectangular cross beam is provided in the construction scenario. Two columns are provided on the lower surface of the rectangular cross beam, and the central axes of the two columns and the central axis of the rectangular cross beam are all on the same vertical plane. The buckling-restrained brace needs to be arranged between the rectangular cross beam and the two columns, and there is a known embedded part fixing point at the midpoint of the central axis of the lower surface of the beam section between the two columns. Now, two target embedded parts need to be installed on the ground. At this time, the known embedded part fixing point can be used as the starting point for wire laying.

[0030] When using this device, first fix the telescopic crossbar through the mounting plate 8 at the known fixed points of the embedded parts, so that the known fixed points of the embedded parts are located on the central axis of the upper surface of the telescopic crossbar, and the central axis of the upper surface of the telescopic crossbar coincides with the central axis of the lower surface of the rectangular crossbeam. Then, according to the actual needs on site, adjust the relative positions of the outer tube 5 and the inner tube 6 to adjust the length of the telescopic crossbar. After adjustment, fix it with the nut 7. Then, adjust the position of the plumb bob 1 by sliding the slider 4 in the chute 3. After adjustment, start the two lasers 2 to emit laser lines vertically downward to the ground. Then, according to the two laser points, the straight line where the two target embedded parts are located can be determined. The points where this straight line intersects the opposite side surfaces of the two columns are the fixed points of the two target embedded parts. Thus, the use of this device is completed; it overcomes the problem of low construction efficiency caused by the complex measurement steps and long time consumption in the existing method for laying out and positioning the embedded parts of the buckling-restrained brace. Embodiment 2

[0031] In this embodiment, a rectangular crossbeam is provided in the construction scene. The lower surface of the rectangular crossbeam is provided with two columns, and the central axes of the two columns and the central axis of the rectangular crossbeam are all on the same vertical plane. The buckling-restrained brace needs to be arranged between the rectangular crossbeam and the two columns, and there is already a known fixed point of the embedded part at each of the two intersection points of the central axis of the lower surface of the rectangular crossbeam and the opposite side surfaces of the two columns. Now, a target embedded part needs to be installed on the ground.

[0032] When using this device, first determine the central axis and the midpoint of the lower surface of the rectangular crossbeam according to the two known fixed points of the embedded parts. Then, fix the telescopic crossbar through the mounting plate 8 at the midpoint of the central axis of the lower surface of the rectangular crossbeam, so that the central axis of the lower surface of the rectangular crossbeam coincides with the central axis of the upper surface of the telescopic crossbar, and record the scale line of the telescopic crossbar at the midpoint of the central axis of the lower surface of the rectangular crossbeam. Then, adjust the position of one of the plumb bobs 1 by sliding the slider 4 in the chute 3 so that it is located at the recorded scale line. Then, start the laser 2 to emit a laser line vertically downward to the ground. At this time, the laser point projected on the ground is the fixed point of the target embedded part. Thus, the use of this device is completed; it overcomes the problem of low construction efficiency caused by the complex measurement steps and long time consumption in the existing method for laying out and positioning the embedded parts of the buckling-restrained brace.
