Description

Technical Field

[0001] This utility model relates to the field of clamp technology, specifically a U-shaped clamp for fixing distribution beams. Background Technology

[0002] Currently, in the construction of cast-in-place box girders, the support system commonly used is a steel pipe-Bailey beam support. The main structural form, from bottom to top, consists of the support foundation, steel pipe, load-bearing beam, Bailey beam, distribution beam, and upper disc-lock support.

[0003] When installing existing distribution beams and Bailey beams, it is generally necessary to install additional fixing mechanisms on the Bailey beams, and then use bolts on the fixing mechanisms to install the Bailey beams and distribution beams together. This is cumbersome to install, and the fixing mechanism cannot be adjusted according to the size of the Bailey beams and distribution beams during installation, resulting in poor performance. In use, the bolts fixing the Bailey beams and distribution beams are easily loosened by factors such as vibration, making the installation unstable.

[0004] Therefore, a U-shaped clamp for fixing the distribution beam is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a U-shaped clamp for fixing distribution beams, which can solve the problem of unstable installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped clamp for fixing a distribution beam, including a U-shaped elbow, both ends of which are provided with threaded holes, each threaded hole having a connecting rod inside, the outer surface of the connecting rod being provided with a first external thread, the first external thread being threadedly connected to the inner wall of the threaded hole; Each of the connecting rods is coaxially mounted with a sliding rod at its top. A clamping steel plate is provided between two sliding rods. Each sliding rod slides through the end of the clamping steel plate. Each sliding rod is coaxially fitted with a fastening nut on its side. A second external thread is provided on the side of each sliding rod. The second external thread is threadedly connected to the corresponding fastening nut. Each sliding rod has a first washer and a second washer coaxially fitted on its side. The bottom of the first washer abuts against the top of the clamping steel plate. An elastic connecting piece connects the first washer and the second washer. A pressure ring is installed at the bottom of the fastening screw sleeve. The bottom of the pressure ring abuts against the top of the second washer.

[0007] Preferably, the diameter of the sliding rod is the same as the end diameter of the U-shaped bend.

[0008] Preferably, the two ends of the U-shaped elbow are provided with a third external thread, and when the clamping steel plate is located between the two ends of the U-shaped elbow, the inner wall of the fastening sleeve engages with the third external thread.

[0009] Preferably, a plurality of anti-slip grooves are provided on the top of the second gasket and the bottom of the pressure ring. When the fastening nut is tightened, the pressure ring engages with the anti-slip grooves on the second gasket.

[0010] Preferably, the elastic connecting piece is made of an elastic metal material.

[0011] Preferably, the surfaces of the U-shaped elbow, the fastening nut, the first external thread, the second external thread, and the third external thread are all provided with a galvanized layer.

[0012] Preferably, the top of the clamp steel plate is equipped with several reinforcing ribs.

[0013] Compared with the prior art, this utility model provides a U-shaped clamp for fixing the distribution beam, which has the following beneficial effects: 1. By rotating the sliding rod, the connecting rod can be rotated. The distance between the sliding rod and the end of the U-shaped elbow can be adjusted by the fit between the first external thread and the threaded hole. Thus, the length of the clamp can be adjusted as needed to improve the performance.

[0014] 2. The elastic force of the elastic connecting piece can apply a reaction force to the fastening threaded sleeve, increasing the friction between the fastening threaded sleeve and the second external thread. The anti-slip groove on the pressure ring and the second washer limits the fastening threaded sleeve, preventing it from loosening, ensuring a stable installation and improving the installation effect.

[0015] 3. A U-shaped clamp can be formed by using a U-shaped elbow and a sliding rod. The clamp steel plate and fastening bolts can be used to fix the Bailey beam chord to the distribution beam, which is convenient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please see Figure 1 - Figure 4 In this embodiment, a U-shaped clamp for fixing a distribution beam includes a U-shaped elbow 1. Both ends of the U-shaped elbow 1 are provided with threaded holes 8. Each threaded hole 8 has a connecting rod 14 inside. The outer surface of the connecting rod 14 is provided with a first external thread 5. The first external thread 5 is threadedly connected to the inner wall of the threaded hole 8. A sliding rod 7 is coaxially installed on the top of each connecting rod 14. By rotating the connecting rod 14, the connecting rod 14 can be controlled to move along the threaded hole 8 in cooperation with the first external thread 5. In this way, the distance between the sliding rod 7 and the end of the U-shaped elbow 1 can be adjusted, and the length of the clamp can be controlled as needed.

[0020] like Figure 1 and Figure 2 As shown, a clamping steel plate 12 is provided between the two sliding rods 7. Each sliding rod 7 slides through the end of the clamping steel plate 12, and a fastening nut 4 is coaxially fitted on the side of each sliding rod 7. A second external thread 6 is provided on the side of each sliding rod 7. The second external thread 6 is threadedly connected to the corresponding fastening nut 4. In actual use, through the cooperation of the clamping steel plate 12 and the sliding rod 7, it can be fitted onto the distribution beam and the Bailey beam chord. Then, by tightening the fastening nut 4, the clamping steel plate 12 can be pressed against the side of the distribution beam or the Bailey beam chord, fixing the distribution beam and the Bailey beam chord together, which is convenient for fixing.

[0021] It should be noted that, as Figure 1 and Figure 4As shown, the diameter of the sliding rod 7 is the same as the end diameter of the U-shaped elbow 1. Both ends of the U-shaped elbow 1 are provided with a third external thread 15. When the clamping steel plate 12 is located between the two ends of the U-shaped elbow 1, the inner wall of the fastening sleeve 4 engages with the third external thread 15. When the height of the distribution beam and the Bailey beam chord is less than the length of the U-shaped elbow 1, when the clamping steel plate 12 contacts the surface of the Bailey beam chord or the distribution beam, both ends of the clamping steel plate 12 will be fitted onto the U-shaped elbow 1. At this time, the worker rotates the fastening sleeve 4 to the end of the U-shaped elbow 1 and, under the action of the third external thread 15, tightly squeezes the second washer 13, pressing the clamping steel plate 12 tightly against the side of the Bailey beam chord or the distribution beam, thus completing the installation.

[0022] It should be noted that the top of the clamp steel plate 12 is equipped with several reinforcing ribs 10. The reinforcing ribs 10 can increase the structural strength of the clamp steel plate 12, so that the clamp steel plate 12 will not deform or bend during use.

[0023] like Figure 2 and Figure 3 As shown, each sliding rod 7 has a first washer 11 and a second washer 13 coaxially fitted on its side. The bottom of the first washer 11 abuts against the top of the clamping steel plate 12. An elastic connecting piece 2 connects the first washer 11 and the second washer 13. A pressure ring 9 is installed at the bottom of the fastening screw sleeve 4. The bottom of the pressure ring 9 abuts against the top of the second washer 13. The elastic connecting piece 2 is made of elastic metal material. In actual use, when the fastening screw sleeve 4 is tightened, the pressure ring 9 at the bottom of the fastening screw sleeve 4 will squeeze the second washer 13, causing the second washer 13 to move with the fastening screw sleeve 4. At this time, the elastic connecting piece 2 is squeezed and deformed. The reaction force generated by the deformation will push the fastening screw sleeve 4, increasing the friction between the fastening screw sleeve 4 and the second external thread 6, and preventing the fastening screw sleeve 4 from loosening during use.

[0024] like Figure 3 As shown, several anti-slip grooves 3 are provided on the top of the second washer 13 and the bottom of the pressure ring 9. When the fastening nut 4 is tightened, the pressure ring 9 engages with the anti-slip grooves 3 on the second washer 13. Through the cooperation of the anti-slip grooves 3, the pressure ring 9 and the second washer 13 can be limited, so that the pressure ring 9 will not rotate relative to the second washer 13, thereby limiting the fastening nut 4 and preventing the fastening nut 4 from loosening.

[0025] It should be noted that the surfaces of the U-shaped elbow 1, the fastening screw 4, the first external thread 5, the second external thread 6, and the third external thread 15 are all coated with a galvanized layer. This provides corrosion protection for the surfaces of the U-shaped elbow 1, the fastening screw 4, the first external thread 5, the second external thread 6, and the third external thread 15, preventing them from being oxidized and corroded by the external environment during use.

[0026] The working principle of the above embodiments is as follows: During installation, the worker rotates the sliding rod 7, which drives the connecting rod 14 to rotate. With the cooperation of the first external thread 5 and the threaded hole 8, the distance between the sliding rod 7 and the U-shaped elbow 1 can be adjusted. After adjustment, the worker places the distribution beam, and the two ends of the U-shaped elbow 1 pass through the Bailey beam chord and the distribution beam. Then, the two ends of the clamp steel plate 12 are put on the corresponding sliding rod 7, and the first shim 11 and the second shim 13 are put on the corresponding sliding rod 7, so that the bottom of the first shim 11 contacts the top of the clamp steel plate 12. Then, the fastening sleeve 4 is placed on the corresponding end of the sliding rod 7 and tightened. During the tightening process, the fastening sleeve 4 will push the second washer 13 to move. When the second washer 13 moves, it will squeeze the elastic connecting piece 2, causing the elastic connecting piece 2 to deform. The deformation generates a reaction force, which can increase the friction between the fastening sleeve 4 and the second external thread 6, preventing the fastening sleeve 4 from loosening. Under the reaction force, the first washer 11 will also push the first washer 11 to press tightly against the top of the clamping steel plate 12, so that the bottom of the clamping steel plate 12 presses tightly against the surface of the distribution beam or Bailey beam chord, fixing the distribution beam to the Bailey beam chord.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
