Description

Technical Field

[0001] The utility model relates to the field of auxiliary positioning, and specifically relates to an auxiliary positioning device for the installation of building steel beams. Background Technique

[0002] Steel beams are steel components widely used in building and structural engineering, with advantages such as strong load-bearing capacity, high construction efficiency, and good economy. It is welded or riveted by steel plates or sections, and the cross-sectional shape is mostly I-shaped, H-shaped, box-shaped, etc., which can adapt to various complex stress conditions. One of the main advantages of the beam is its high strength and light weight characteristics, and it has a wide range of applications in projects such as large buildings, bridges, and industrial factories.

[0003] When installing steel beams, most of them are hoisted. First, the column is tied with a single wire rope, and the lifting point is selected at a position 1 / 3 of the column length from the column end. The column is lifted by the rotation method, and the steel column is lifted to the installation position. When installing and fixing, usually workers fix the connecting plates between the steel beams with bolts. Often, they also need to hold the bolts steadily by hand to position them, and then hammer the bolts into the bolt holes.

[0004] Since the workers still need to hold the bolts steadily by hand for positioning and then hammer them during the installation of the above-mentioned steel beams, there are actually problems of slightly deviated positioning and the possibility of hitting the hand. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an auxiliary positioning device for the installation of building steel beams to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A device includes a steel beam, a connecting plate, and a fixing component. The fixing component is composed of a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are rotationally connected through a rotating shaft. The outer wall of the first clamping plate and the second clamping plate in contact with each other is provided with a first clamping groove corresponding to the bolt, and the outer wall of the second clamping plate is provided with a second clamping groove corresponding to the first clamping groove. The end of the rotating shaft is provided with a sleeve corresponding to the fixing hole, and a ventilation component is arranged in the sleeve. Moreover, the distance between the sleeve and the second clamping groove is the same as the distance between the fixing holes.

[0007] By adopting the above technical solution, the outer wall of the sleeve is in contact with the inner wall of the fixing hole. The ventilation component in the sleeve will reduce the resistance when the sleeve enters the fixing hole, making the sleeve enter the fixing hole more smoothly, so that the fixing component is fixed more accurately and stably on the outer wall of the connecting plate, ensuring the stability of the positioning.

[0008] Furthermore, the combination of the first clamping plate and the second clamping plate is designed in a scissor shape, and handles are installed at the ends of the first clamping plate and the second clamping plate.

[0009] By adopting the above technical solution, the first clamping plate and the second clamping plate will not easily fall off during movement, ensuring that the first clamping plate and the second clamping plate will fix the screw rod. The handle eliminates the operation of manually holding the screw rod, ensuring the safety of fixation.

[0010] Furthermore, the diameter of the sleeve corresponds to the diameter of the fixing hole, and the end corners of the fixing hole are designed with chamfers.

[0011] By adopting the above technical solution, when the sleeve is inserted into the fixing hole, the fixing hole restricts the sleeve. When the sleeve is taken out, the sleeve is pulled out of the fixing hole, realizing the convenient removal of the sleeve, so that the sleeve is convenient to enter and also convenient to take out.

[0012] Furthermore, the ventilation component is composed of through holes and side grooves. The through holes are penetratedly opened on the sleeve and the rotating shaft, and the through holes on the sleeve and the rotating shaft are connected.

[0013] By adopting the above technical solution, the resistance of the sleeve entering the fixing hole is reduced, making the sleeve enter the fixing hole more smoothly and ensuring the smooth movement of the sleeve and the rotating shaft.

[0014] Furthermore, multiple groups of side grooves are equiangularly opened on the outer wall of the sleeve, and the side grooves are designed as semi-circular grooves.

[0015] By adopting the above technical solution, the friction and resistance when the outer wall of the sleeve contacts the inner wall of the fixing hole are reduced, and thus the sleeve enters the fixing hole more smoothly.

[0016] Furthermore, the first clamping groove and the second clamping groove have the same shape, and the diameters of the first clamping groove and the second clamping groove correspond to the diameter of the sleeve.

[0017] By adopting the above technical solution, while the screw rod is fixed, the first clamping groove and the second clamping groove are tightly closed together, so that the screw rod is fixed near the fixing hole where the sleeve is fixed, thereby ensuring the fixed position of the first clamping plate and the second clamping plate during use.

[0018] In summary, the main beneficial effects of the present utility model are as follows:

[0019] The present utility model is provided with a first clamping plate, a second clamping plate and a sleeve. Under the action of the sleeve, the rotating shaft is fixed in the fixing hole, effectively positioning the position of the connecting plate to be fixed. At the same time, the bolt rod is clamped and fixed by the first clamping plate and the second clamping plate. Hold the handle tightly, eliminating the action of manually stabilizing the screw rod, improving the convenience of the fixing operation, and at the same time reducing the probability of hitting the hand when knocking the bolt. When the first clamping plate and the second clamping plate are opened, loosen the handle and pull the sleeve out of the fixing hole, so that the positioning restriction is released, and the position to be fixed can be easily replaced.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0026] The following will describe the embodiments according to the overall structure of the present utility model.

[0027] An auxiliary positioning device for installing a building steel beam, as Figure 1 - Figure 4 shown, includes a steel beam 21, a connecting plate 22 and a fixing component. The fixing component is composed of a first clamping plate 1 and a second clamping plate 3. The first clamping plate 1 and the second clamping plate 3 are rotatably connected through a rotating shaft 5. The first clamping plate 1 and the second clamping plate 3 will fix the bolt. The outer wall of the first clamping plate 1 and the second clamping plate 3 in contact with each other is provided with a first clamping groove 2 corresponding to the bolt, and the outer wall of the second clamping plate 3 is provided with a second clamping groove 4 corresponding to the first clamping groove 2. The first clamping groove 2 and the second clamping groove 4 limit the screw rod. The end of the rotating shaft 5 is provided with a sleeve 6 corresponding to the fixing hole 23, and a ventilation component is provided in the sleeve 6. Moreover, the distance between the sleeve 6 and the second clamping groove 4 is the same as the distance between the fixing hole 23 and the fixing hole 23. When the sleeve 6 is inserted into the fixing hole 23, the outer wall of the sleeve 6 is in contact with the inner wall of the fixing hole 23. The ventilation component in the sleeve 6 will reduce the resistance when the sleeve 6 enters the fixing hole 23, making the sleeve 6 enter the fixing hole 23 more smoothly, so that the fixing component is more accurately and stably fixed on the outer wall of the connecting plate 22, ensuring the stability of the positioning.

[0028] Please refer to Figure 1 and Figure 3, after the first splint 1 and the second splint 3 are combined, they are designed in a scissor shape, and handles 11 are installed at the ends of both the first splint 1 and the second splint 3. Under the action of the first splint 1 and the second splint 3, the screw can be restricted by the first splint 1 and the second splint 3, and because the sleeve 6 is restricted, the first splint 1 and the second splint 3 will not fall off easily during movement, ensuring that the first splint 1 and the second splint 3 will fix the screw. The handle 11 eliminates the operation of manually holding the screw, ensuring the safety of fixation.

[0029] Please refer to Figure 1 , the diameter of the sleeve 6 corresponds to the diameter of the fixing hole 23, and the end corners of the fixing hole 23 are designed with bevels. When the sleeve 6 is inserted into the fixing hole 23, the fixing hole 23 restricts the sleeve 6. When the sleeve 6 is taken out, the sleeve 6 is pulled out of the fixing hole 23, realizing the convenient removal of the sleeve 6, so that the sleeve 6 is convenient to enter and also convenient to take out.

[0030] Please refer to Figure 1 , the ventilation component is composed of a through hole 7 and a side groove 8. The through hole 7 is penetrated and opened on the sleeve 6 and the rotating shaft 5, and the through holes 7 on the sleeve 6 and the rotating shaft 5 are connected. Under the action of the through hole 7, the resistance of the sleeve 6 entering the fixing hole 23 is reduced, making the sleeve 6 enter the fixing hole 23 more smoothly, ensuring that the sleeve 6 and the rotating shaft 5 can move smoothly.

[0031] Please refer to Figure 1 , multiple groups of side grooves 8 are equiangularly opened on the outer wall of the sleeve 6, and the side grooves 8 are designed as semi-circular grooves, ensuring the smooth sliding of the sleeve 6 in the fixing hole 23. The side grooves 8 reduce the friction and resistance when the outer wall of the sleeve 6 contacts the inner wall of the fixing hole 23, and thus the sleeve 6 enters the fixing hole 23 more smoothly.

[0032] Please refer to Figure 1 and Figure 3 , the shapes of the first clamping groove 2 and the second clamping groove 4 are the same, and the diameters of the first clamping groove 2 and the second clamping groove 4 correspond to the diameter of the sleeve 6. The first clamping groove 2 and the second clamping groove 4 restrict the screw. At the same time, the sleeve 6 cooperates with the first splint 1 and the second splint 3 to enter the fixing hole 23, so that while the screw is fixed, the first clamping groove 2 and the second clamping groove 4 are tightly closed together, making the screw fixed near the fixing hole 23 where the sleeve 6 is fixed, thus ensuring the fixed position when the first splint 1 and the second splint 3 are used.

[0033] The working principle of the utility model is as follows: when the steel beam 21 needs to be installed, firstly, the sleeve 6 is placed in the fixing hole 23 of the connecting piece of the steel beam 21, and then the bolt rod is placed in the first clamping groove 2 and the second clamping groove 4, and inserted into the fixing hole 23. The through hole 7 in the sleeve 6 reduces the resistance of the sleeve 6 when entering the fixing hole 23, and the side groove 8 on the outer wall of the sleeve 6 also reduces the resistance of the sleeve 6 when entering the fixing hole 23. At this time, the sleeve 6 is fixed in the fixing hole 23 and is tightly attached to the inner wall of the fixing hole 23. At the same time, the handle 11 is tightened to tighten the first clamping plate 1 and the second clamping plate 3, and the bolt is fixed, and then the bolt is struck; the handle 11 is loosened, and the sleeve 6 is pulled out of the fixing hole 23 to release the positioning restriction, so that the fixed position can be easily changed.
