Description

Technical Field

[0001] The utility model relates to the field of auxiliary positioning of purlin installation, in particular to an auxiliary positioning device for roof purlins. Background Art

[0002] In construction projects, the installation of roof purlins is a crucial link, which is directly related to the stability and safety of the building structure. In order to ensure the accuracy and stability of the purlin installation, it is necessary to use an auxiliary positioning device to locate and fix the position of the purlin. For example, a purlin installation tool with a patent number of CN 216543055 U is provided. The purlin installation tool is provided with a limit portion on the first fixing component to position the purlin to the axial position of the main beam, and a buckle portion is provided under the second fixing component to clamp the main beam. This design is relatively simple and lacks flexibility. First, since the specifications and sizes of the main beams and purlins used in different roof installations may be different and of different thicknesses, the fixings of the prior art cannot adapt to main beams and purlins of different sizes. Secondly, due to the lack of an effective fixing mechanism, the purlins are prone to skew, non-horizontal, and non-perpendicular to the main beam during installation. This not only affects the flatness and aesthetics of the roof, but more importantly, it may cause structural safety hazards and affect the overall stability of the building. Therefore, it is particularly necessary to provide an auxiliary positioning device with better adaptability and stability. Utility Model Content

[0003] The utility model aims at the limitations of the existing purlin auxiliary positioning device in adapting to purlins and main beams of different specifications and sizes and ensuring the clamping stability of the purlins, and proposes a roof purlin auxiliary positioning device.

[0004] The utility model provides a roof purlin auxiliary positioning device, comprising a left support arm, a right support arm and an intermediate support arm. One end of the left support arm and the right support arm are respectively hinged to the intermediate support arm through a hinge, so that the entire device can be folded or unfolded as needed. A lock is provided at the lower end of the hinge, and when the left support arm, the right support arm and the intermediate support arm are fully unfolded and connected in a straight line, the unfolded state can be locked by the lock.

[0005] In addition, it also includes a first clamp, a second clamp and a third clamp. The second clamp and the third clamp are located on both sides of the first clamp. The first clamp is used to clamp the main beam so that the device is firmly connected to the main beam. The second clamp and the third clamp are used to clamp two adjacent purlins so that the purlins can be positioned at a predetermined position. The axial direction of the first clamp is perpendicular to the axial directions of the second clamp and the third clamp, so that the clamped adjacent purlins are perpendicular to the main beam and parallel to each other.

[0006] The first clamp is fixedly connected to the middle support arm through a telescopic rod. When the thickness of the purlin changes, the first clamp can adapt to the change of the thickness of the purlin by telescoping the telescopic rod, ensuring that the main beam can always be attached and clamped.

[0007] Furthermore, the cross section of the telescopic rod is a regular polygon to prevent the first clamp and the middle support arm from rotating relative to each other.

[0008] The second clamp is slidably connected to the left support arm so that the second clamp can slide on the left support arm. Construction personnel can slide the second clamp to adjust the spacing between adjacent purlins. A limiter is provided at the sliding connection between the second clamp and the left support arm so that the second clamp can be locked on the left support arm after being adjusted into place. The third clamp is fixedly connected to the end of the right support arm.

[0009] Furthermore, a scale for adjusting the spacing between adjacent purlins is provided on the side of the left support arm. When the third clamp clamps a purlin, the second clamp can slide with reference to the scale to adjust the spacing between adjacent purlins.

[0010] Preferably, a sliding block is fixedly connected to the upper end of the second clamp, and a sliding groove is formed at the lower end of the left supporting arm, so that the second clamp can slide on the sliding groove.

[0011] Further, the limiting member provided at the sliding connection is a tightening bolt. A threaded hole is provided at the position of the slider corresponding to the slide slot, and when the second clamp needs to be fixed, the tightening bolt is screwed into the threaded hole of the slider to fix the second clamp at a certain position of the slide slot.

[0012] Preferably, the first clamp includes a U-shaped clamp and a first clamping bolt. A threaded through hole is opened on one side wall of the U-shaped clamp, and the end of the first clamping bolt is rotatably connected to a clamp. When the bolt is tightened, the clamp will move closer to the main beam and clamp.

[0013] Preferably, the second clamp is the same as the third clamp, and both include a baffle, a bottom plate, and a support rod. The baffle is used to abut against one side of the purlin, and the support rod is fixedly connected to two ends of the bottom plate. A threaded hole is formed on the support rod, and a second clamping bolt is arranged in the threaded hole. A pressure block is rotatably connected to the end of the second clamping bolt, and the second clamping bolt is tightened so that the pressure block clamps the purlin.

[0014] Compared with the prior art, it has the following beneficial effects:

[0015] The first clamp is fixedly connected to the middle support arm through a telescopic rod. When the thickness of the purlin changes, the first clamp can adapt to the thickness of different purlins by telescoping the telescopic rod, ensuring that the first clamp can always fit and clamp the main beam, thereby improving the applicability of the device.

[0016] Each clamp is clamped by bolts and can adapt to purlins and main beams of different specifications and sizes. This clamping method can improve the stability of purlin positioning, avoid shaking and skewing, and make the purlin installation process more accurate and reliable.

[0017] Each support arm is hinged so that the whole device can be folded or unfolded as needed. At the same time, when placing the purlins, the support arms can be folded to avoid obstruction and facilitate operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0024] Example:

[0025] like Figures 1 to 3As shown, the utility model provides a roof purlin auxiliary positioning device, including a left support arm 1, a right support arm 2 and an intermediate support arm 3. One end of the left support arm 1 and the right support arm 2 is connected to the intermediate support arm 3 through a hinge 4, so that the device can be folded or unfolded according to construction needs. A lock buckle 5 is provided at the lower end of the hinge. When the left support arm 1, the right support arm 2 and the intermediate support arm 3 are fully unfolded and connected in a straight line, the construction personnel can lock the unfolded state through the lock buckle 5. When the purlin 10 is placed on the main beam 9, the support arm can also be folded to avoid obstruction. When storing, the support arm can also be folded for easy carrying and space saving.

[0026] In addition, the device also includes a first clamp 6, a second clamp 7 and a third clamp 8. The second clamp 7 and the third clamp 8 are respectively located on both sides of the first clamp 6, and the three together form a stable clamp combination. The first clamp 6 clamps the main beam 9 to firmly connect the device to the main beam 9. The second clamp 7 and the third clamp 8 clamp two adjacent purlins 10 to position the purlins 10 at a predetermined position. The axial direction of the first clamp 6 is perpendicular to the axial directions of the second clamp 7 and the third clamp 8, so that the clamped adjacent purlins 10 are parallel to each other, thereby improving the flatness and stability of the roof.

[0027] Since the purlin 10 is mounted on the main beam 9, there is a gap between the support arm and the first clamp 6. If the thickness of the purlin 10 increases, the gap will also increase, so that the first clamp 6 cannot completely fit and clamp the main beam 9. The first clamp 6 is fixedly connected to the middle support arm 3 by setting a telescopic rod 11. When the thickness of the purlin 10 changes, the first clamp 6 can adapt to this change by extending and retracting the telescopic rod 11, ensuring that it can always fit and clamp the main beam 9.

[0028] In order to prevent the first clamp 6 and the middle support arm 3 from rotating relative to each other during operation, the telescopic rod 11 is a rod with a regular polygonal cross section.

[0029] The second clamp 7 is slidably connected to the left support arm 1. The second clamp 7 can slide on the left support arm 1, and the construction personnel can adjust the spacing between adjacent purlins 10 according to actual needs. A limiter 12 is provided at the sliding connection so that the second clamp 7 can be fixed on the left support arm 1. The third clamp 8 is fixedly connected to the end of the right support arm 2. A scale 13 is provided on the side of the left support arm 1. After the third clamp 8 clamps a purlin 10, the construction personnel can slide the second clamp 7 with reference to the scale 13 to accurately adjust the spacing between adjacent purlins 10, thereby improving work efficiency and positioning accuracy.

[0030] As another example, Figure 3As shown, the upper end of the second clamp 7 is fixedly connected with a slider 71, and the lower end of the left support arm 1 is provided with a slide groove 72, so that the second clamp 7 can slide along the slide groove 72. When the position of the second clamp 7 needs to be adjusted, the second clamp 7 is slid along the direction of the slide groove 72. A limiter 12 is provided at the sliding connection, and the limiter 12 is a tightening bolt 121. A threaded hole is provided at the position of the slider 71 corresponding to the slide groove 72. The tightening bolt 121 is screwed into the threaded hole of the slider 71 to fix the second clamp 7 at a certain position of the slide groove 72.

[0031] As another example, Figure 2 As shown, the first clamp 6 includes a U-shaped clamp plate 61 and a first clamping bolt 62. A threaded through hole is opened on one side wall of the U-shaped clamp plate 61. The end of the first clamping bolt 62 is rotatably connected to a clamp plate 63. The clamp plate 63 allows the bolt to clamp the main beam 9 between the U-shaped clamp plates 61 when tightened. This not only improves the clamping force of the clamp, but also enables the clamp to adapt to main beams 9 of different thicknesses, thereby improving the versatility of the device.

[0032] As another example, Figure 3 As shown, the second clamp 7 and the third clamp 8 are the same, and both include a baffle 73, a bottom plate 74 and a support rod 75. The baffle 73 is used to abut against one side of the purlin 10, and the support rod 75 is fixedly connected to the two ends of the bottom plate 74. A threaded hole is opened on the support rod 75, and a second clamping bolt 76 is arranged on the threaded hole. The end of the second clamping bolt 76 is rotatably connected to a pressure block 77. When the bolt is tightened, the pressure block 77 will approach the purlin 10 and generate sufficient pressure, thereby clamping the purlin 10. This design allows the clamp to adapt to purlins 10 of different sizes.

[0033] The working principle of the auxiliary positioning device of the roof purlin 10 of this application:

[0034] First, the main beam 9 is clamped using the first clamp 6 to ensure a firm connection between the device and the main beam 9 .

[0035] Then, the right support arm 2 is lowered, the lock buckle 5 is locked, and the clamping bolt of the third clamp 8 is tightened to clamp the first purlin 10 .

[0036] Next, lower the left support arm 1 and lock the buckle 5 in the same way. Clamp another purlin 10 with the second clamp 7. At this time, the left support arm 1, the right support arm 2 and the middle support arm 3 are in the same straight line. Slide the second clamp 7 and adjust the spacing between adjacent purlins 10 with reference to the scale 13 on the left support arm 1. After the adjustment is completed, lock the position of the purlin 10 with the stopper 12. At this time, the two adjacent purlins 10 are parallel to each other and perpendicular to the main beam 9.

[0037] Due to the telescopic performance of the telescopic rod 11 , the first clamp 6 can maintain a close fit and clamping with the main beam 9 by extending and retracting the telescopic rod 11 when the thickness of the purlin 10 changes.

[0038] Each clamp is clamped by bolt compression, which can adapt to purlins 10 of different specifications and sizes and prevent the purlins 10 from tilting or shaking during installation.

[0039] The above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention belong to the protection scope of the present technical solution.
