Description

Technical Field

[0001] The present application relates to the technical field of support frame equipment, and in particular to a simple support frame for a channel steel formwork. Background Art

[0002] During the concrete pouring process of water conservancy and hydropower construction, before pouring the concrete base plate and cushion layer, formwork needs to be erected to control the size of the structure. For cushion layers and base plates with a small thickness (generally 0.1 to 0.3 meters), channel steel is usually used as the formwork. When in use, the side with the wing plate faces outward and the side without the wing plate faces inward as the formwork. After the channel steel is placed, fixed piles need to be driven at intervals to fix the channel steel to prevent the channel steel from deflecting during the concrete pouring process. The traditional method of fixing the channel steel generally uses a short steel bar head, which is close to the channel steel and driven on the base surface to fix the channel steel. Since the steel bar head needs to be close to the channel steel, it is easy to cause the channel steel position to shift during driving, and the operation is relatively inconvenient. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides a simple support frame for channel steel formwork, which can prevent the position of the channel steel from being easily offset when the channel steel is fixed and installed.

[0004] The present application discloses a simple support frame for a channel steel formwork, comprising a channel steel, and also comprising: a fixed sleeve, a rotating shaft, a connecting shaft, a second sleeve, and a fastening nail; the fixed sleeve is fixedly arranged on one side of the channel steel with a wing plate, the rotating shaft is arranged in the fixed sleeve, the two ends of the rotating shaft are connected to the connecting shaft, the two connecting shafts are connected to each other, and the connecting ends are connected to the second sleeve, and the fastening nail is inserted in the second sleeve.

[0005] Optionally, the rotating shaft is connected to two connecting shafts to form a triangular bracket.

[0006] Optionally, a retaining ring is provided on the upper portion of the rotating shaft, and the retaining ring abuts against the top of the fixed sleeve.

[0024] In response to the above problems, an embodiment of the present application provides a simple support frame for a channel steel formwork. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 The illustrated simplified support frame for a channel steel formwork comprises a channel steel 1, a fixed sleeve 2, a rotating shaft 3, a connecting shaft 4, a second sleeve 5, and a fastening nail 6. In this application, the fixed sleeve 2 is fixedly mounted on the side of the channel steel 1 with the wing plate, and the rotating shaft 3 is disposed within the fixed sleeve 2. Thus, the rotating shaft 3 can carry other components mounted thereon and rotate on the fixed sleeve 2. Connecting shafts 4 are connected to both ends of the rotating shaft 3. The two connecting shafts 4 are connected to each other, and the connecting ends are connected to the second sleeve 5. The fastening nail 6 is inserted into the second sleeve 5.

[0026] Thus, a fixing sleeve 2 is provided on the side of the channel steel 1 with the flange, and a second sleeve 5 is connected to the fixing sleeve 2 by a connecting shaft, and then a fastening nail 6 is passed through the fastening nail 6 and fastened to the ground. When in use, the second sleeve 5 is pulled out, and when not in use, it is rotated under the flange of the channel steel 1. The fastening position of the fastening nail 6 is extended by the connecting shaft 4, thereby preventing the fastening nail 6 from being close to the channel steel 1 when fastening the channel steel 1, causing the channel steel 1 to be accidentally deflected during installation.

[0027] In one embodiment, Figure 2 As shown, to improve support stability, the rotating shaft 3 is connected to two connecting shafts 4 to form a triangular bracket. In actual use, a steel pipe with a length of L = 5cm and a diameter of 20 is used as a fixed sleeve 2. A steel pipe with a length of L = 8cm and two steel bars with a length of L = 20cm are used to form the triangular bracket. Each steel bar is welded together. Before welding, the Φ20 steel sleeve is passed through the short side steel bars of the triangular bracket, and then the triangular bracket is welded together. The fixed sleeve 2 is welded to the side of the channel steel 1 with the wing plate. At this time, the triangular bracket can be rotated by the fixed sleeve 2. At the other end of the triangular bracket, a steel pipe with a length of L = 8cm and a diameter of 20 is welded and fixed as a second sleeve 5. A 30cm long Φ18 steel bar is used as a fastening nail 6. One end is made into a pointed cone shape, and the other end is welded to a Φ25 circular steel arc gasket to prevent the fixing rod from falling off the sleeve when the channel steel is transported. On the side of the channel steel with the wing plate, a group of brackets of this application is welded every 1 to 2 meters.

[0028] In one embodiment, Figure 2 As shown, due to the use of a triangular bracket, in order to prevent the top of the triangular bracket from falling and scratching the fixed sleeve 2, a retaining ring 31 is provided on the upper part of the rotating shaft 3, and the retaining ring 31 abuts against the top of the fixed sleeve 2.

[0029] In one embodiment, Figure 2 As shown, in order to facilitate the folding of the triangular bracket, a torsion spring 32 is provided between the retaining ring 31 and the fixed sleeve 2 .

[0030] In one embodiment, to prevent the fastening nail 6 from falling out, a thread is provided at the center of the middle portion of the second sleeve 5, and a thread is provided at the middle portion of the fastening nail 6. The thread at the middle portion of the second sleeve 5 is threadedly connected to the thread at the middle portion of the fastening nail 6. In this way, when the second sleeve 5 is folded, the thread at the middle portion of the second sleeve 5 is threadedly connected to the thread at the middle portion of the fastening nail 6 to prevent it from falling out upward. The threaded connection of the present application is set according to the specific folding requirements. For example, when the tripod is set as a right-angle tripod with the right-angle side at the bottom, the thread of the fastening nail 6 is set at its bottom. The specific position setting is set according to the needs and is not limited to a specific position.

[0031] In one embodiment, Figure 3As shown, in order to facilitate the fastening nail 6 to be stored in the side of the channel steel along with the tripod, the present application sets a rotating shaft seat 41 on one side of the tripod, and a rotating shaft 52 is set on the rotating shaft seat 41. One side of the rotating shaft 52 is rotated and connected to a sleeve 51, and finally fixedly connected to the second sleeve 5. In this way, the fastening nail 6 can be stored horizontally in the channel steel 1 according to the rotation of the tripod, which is convenient for transportation.
