DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model relates to a cantilever type steel beam upper scaffold vertical rod fixing device. Figures 1-6 The cantilever type steel beam upper scaffold vertical rod fixing device will be described in detail.

[0027] The cantilever type steel beam upper scaffold vertical rod fixing device of the utility model mainly comprises an upper connecting plate 4, an upper connecting rod 5, a sleeve 6, a sleeve pipe 8, a lower connecting rod 11 and a lower connecting plate 12. The upper connecting plate 4 and the lower connecting plate 12 are located above and below the steel beam 7 respectively, and one end of the steel beam 7 is fixed through the embedded plate 13. The lower connecting rod 11 passes through the lower connecting plate 12 and is fixedly connected with the lower connecting plate 12 through the first nut 21, and the upper connecting rod 5 passes through the upper connecting plate 4. The upper connecting rod 5 is provided with the second nipple 102 located above the upper connecting plate 4 and threadedly connected with the second nut 22.

[0028] The sleeve 6 is fixed at the top of the lower connecting rod 11, and the bottom of the upper connecting rod 5 is provided with the first nipple 101 threadedly connected with the internal thread of the sleeve 6, and the upper connecting rod 5 and the lower connecting rod 11 are connected through the sleeve 6, so that the device can adapt to steel beams 7 of different heights. The lower connecting rod 11 is composed of the sleeve 6 and a rod, and the sleeve 6 is fixed at the top of the lower connecting rod 5. The inside of the sleeve 6 is provided with the internal thread threadedly connected with the first nipple 101 at the bottom of the upper connecting rod 5.

[0029] AsFigure 5 and Figure 6 As shown, a sleeve 8 is fixed in the middle of the upper connecting plate 4. The sleeve 8 is connected to the upper connecting plate 4 by full welding to ensure its load-bearing capacity. The scaffold uprights (the bottom end of the steel pipe disc buckle frame) can be directly inserted into the sleeve 8.

[0030] like Figure 2 As shown, the lower part of the lower connecting rod 11 has a third thread 103 and a fourth thread 104 with opposite directions of rotation and threaded to the first nut 21. The two first nuts 21, which are distributed opposite to each other, are located on the top and bottom surfaces of the lower connecting plate 12 and are tightened to fix the lower connecting rod 11 to the lower connecting plate 12.

[0031] To ensure a secure connection between the nut and the connecting plate, a first washer 31 is provided between the first nut 21 and the lower connecting plate 12, and a second washer 32 is provided between the second nut 22 and the upper connecting plate 4.

[0032] Because the device of this utility model can be assembled into a fixed device, it needs to have a certain load-bearing capacity. Therefore, there are certain requirements for the device itself, and the main body material of this device is Q235. The upper connecting rod 5 has only two threaded positions, namely the first thread 101 and the second thread 102. The lower connecting rod 11 has only two threaded positions at the lower part, namely the third thread 103 and the fourth thread 104. A baffle 1 is welded to the top of the upper connecting rod 5 to prevent the upper connecting rod 5 from falling during disassembly. The upper connecting rod 5 is connected to the connecting plate 4 by a second nut 22 to facilitate subsequent disassembly.

[0033] like Figure 3 and Figure 4 As shown, the four corners of the upper connecting plate 4 and the lower connecting plate 12 are respectively provided with connecting holes 9 for the upper connecting rod 5 and the lower connecting rod 11 to pass through. The connecting holes 9 are elongated ellipses and extend in the width direction of the steel beam 7. The size of the connecting holes 9 is determined according to the diameter of the upper and lower connecting rods. Because the modular arrangement of the scaffolding may not always result in eccentricity, causing the sleeve 8 to not correspond to the bottom of the scaffolding upright, the connecting holes 9 are designed as elongated ellipses so that the connecting rods can move left and right to accommodate different types of steel beams 7.

[0034] Compared to the lower connecting plate 12, the upper connecting plate 4 has an additional sleeve 8 to facilitate the installation of scaffold uprights. The size of the sleeve 8 is consistent with the style of common steel pipes and scaffolding on the market.

[0035] The use of the cantilevered steel beam scaffolding upright fixing device of this utility model is divided into two steps: installation and disassembly.

[0036] 1. Installation equipment: the first nut 21 and the first gasket 31 on the top are passed through the lower end of the lower link 11, then the lower link 11 is passed through the connecting hole 9 of the lower connecting plate 12, the first nut 21 and the first gasket 31 on the bottom are passed through the lower end of the lower link 11, then the first nuts distributed on the top are tightened, so that the lower link 11 and the lower connecting plate 12 are fixed, the third thread hole 103 and the fourth thread hole 104 on the top and bottom of the lower connecting plate 12 are positive and negative threads, which can avoid the sliding of the first nut 21 on the bottom when the first nut 21 on the top is tightened, and can ensure that the link rod does not move up and down. The upper link 5 adopts the same steps, the second nut 22 and the second gasket 32 are passed through the upper link 5, then the upper link 5 is passed through the connecting hole 9, the bottom of the upper link 5 is provided with the first thread hole 101, which is threadedly connected with the sleeve 6 on the lower link 11, finally the device is vertically sleeved into the steel beam 7, then the nuts at the upper and lower connecting plates are tightened, and the device splicing is completed.

[0037] 2. Disassembly of the device: first, loosen the nuts fixing the upper and lower links, when the second nut 22 is screwed through the range of the second thread hole 102, the upper link 5 naturally descends, because the top end of the upper link 5 is provided with the baffle 1, at this time the device is still a whole, but the upper connecting plate 4 can move up and down because the second nut 22 has been loosened, and can be taken out from the steel beam 7.

[0038] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can understand the transformation or replacement within the technical range disclosed by the present application, which should be covered in the scope of the present application.
