Technical Field

[0001] The utility model relates to the technical field of safety protection equipment for steel structure installation, in particular to a safety rope hanging support structure for a steel roof truss. Background Art

[0002] According to the statistics of accidents in the construction industry in recent years, the incidence of high-altitude fall accidents is the highest and most dangerous. The lack of safety belt hanging points or lifelines in the high-altitude working areas is one of the main causes of high-altitude fall accidents. In order to scientifically prevent the safety risks of high-altitude working on the construction site, when installing the steel roof purlins and roof horizontal supports, it is necessary to tie a lifeline (safety rope) on the main roof beam. Usually, an angle steel is welded on the flange of each roof frame as a support rod. Then connect the wire rope to complete the installation of the safety rope.

[0003] After the construction is completed, the existing method needs to cause certain damage to the steel structure before the support rod can be removed, which is time-consuming and labor-intensive and cannot be repeated. The existing detachable safety rope support rod cannot meet the needs of fixing H-shaped steel with an inclined bottom surface. For example, the patent with publication number CN220395270U discloses an adjustable safety rope suspension pole support device for high-altitude operations on steel structures. The device can simultaneously fix both sides of the H-shaped steel wing plate through the X-shaped hinge of the first connecting plate and the second connecting plate, making it more stable and ensuring the safety of workers. It can also adapt to H-shaped steels of different sizes and improve work efficiency. It is only suitable for H-shaped steels with flat bottom structures. For I-shaped ...

[0004] In view of this, we propose a steel roof truss safety rope hanging support structure. Through an adjustable angle vise, the support rod can be fixed on the surface of the I-beam with different inclination angles, thereby improving the use range of the support rod. Utility Model Content

A fixing ring is installed on the surface of the rod body, and one of the two clamps installed on the base can be removed according to needs. When the support rod is fixed at both ends of the I-beam, the support rod can use two clamps to fix at the corners of the I-beam, so that the support rod is fixed more firmly. Since the fixing plate and the inclination axis are connected to the fastening bolt through the rotating shaft, the fixing plate will not be driven to rotate during the rotation of the fastening bolt, so that the fixing plate can always maintain a fixed direction.

[0009] Preferably, the fastening bolt and the top plate maintain an inclination angle of 140° to 260°, and since the fixing plate of the vise is installed on the surface of the inclination axis, the vise can be fixed on the surface of the inclined I-beam.

[0010] Preferably, the two clamps are perpendicular to each other, and the rod body is perpendicular to the base. Through the two clamps that are perpendicular to each other, the support rod can be fixed to the corner of the I-beam using two vises at the same time.

[0011] Preferably, the rod body is threadedly connected to the base, a limiting joint is provided at the top of the rod body, and a threaded structure is provided on the surface of the limiting joint. The limiting bolt on the surface of the limiting joint can be removed, and then the rod body is connected through the threaded connection of the limiting joint, so that the two rod bodies are connected, thereby increasing the height of the rod body, by setting the rod body and the limiting joint.

[0012] Preferably, the limit joint has a groove structure built in, and a limit bolt is passed through one side of the limit joint. The groove structure can fix the steel wire rope to limit the movement of the steel wire rope, and the limit bolt passing through can further fix the steel wire fixed inside the limit joint.

[0014] The utility model provides a steel roof truss safety rope hanging support structure, which has the following beneficial effects:

[0015] (1) The steel roof truss safety rope hanging support structure is provided with a vise so that when the support rod is installed on the surface of the I-beam, the top plate of the vise fits the inclined surface of the bottom end of the I-beam through the inclination axis, so that the vise of the clamp at the bottom end of the support rod is firmly fixed on the surface of the I-beam, thereby expanding the use range of the support rod and reducing the occurrence of the situation where the support rod cannot be installed.

[0016] (2) The steel roof truss safety rope hanging support structure is provided with a rod body and a limit joint, so that when the support rod faces a steel house with a large span, the height of a single support rod may not be enough, and the height of the rod body needs to be increased. The limit bolt on the surface of the limit joint can be removed, and then the rod body is connected through the threaded connection of the limit joint to connect the two rod bodies, thereby increasing the height of the rod body, which is more efficient than traditional welding.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0025] A steel roof truss safety rope hanging support structure includes a rod body 1 and a base 2, the bottom end of the rod body 1 is provided with a base 2, the base 2 is provided with two clamps 3, the bottom ends of the two clamps 3 are respectively provided with a vise 4, the vise 4 includes a top plate 41 and an inclination shaft 42, the bottom end of the top plate 41 is connected with the inclination shaft 42, the inclination shaft 42 passes through the connecting shaft 43, the rotating shaft 43 is connected to the fastening bolt 44, and the fastening bolt 44 passes through the bottom end of the clamp 3. A fixing ring 5 is installed on the surface of the rod body 1, and the two clamps 3 installed on the base 2 can be removed one by one according to needs. When the support rod is fixed to the two ends of the I-beam, the support rod can use two clamps 3 to fix it at the corners of the I-beam, so that the support rod is fixed more firmly. Since the fixing plate and the inclination shaft 42 are connected to the fastening bolt 44 through the rotating shaft 43, the fixing plate will not be driven to rotate during the rotation of the fastening bolt 44, so that the fixing plate can always maintain a fixed direction.

[0026] The fastening bolt 44 and the top plate 41 maintain an inclination angle of 140° to 260°. Since the fixing plate of the vise 4 is installed on the surface of the inclination shaft 42, the vise 4 can be fixed on the surface of the inclined I-beam, effectively improving the application range of the support rod.

[0027] The two clamps 3 are perpendicular to each other, and the rod body 1 is perpendicular to the base 2. Through the two clamps 3 that are perpendicular to each other, the support rod can be fixed to the corner of the I-beam using two vises 4 at the same time to keep the support rod stable.

[0028] The rod body 1 is threadedly connected to the base 2, and a limit joint 6 is arranged at the top of the rod body 1. A threaded structure is arranged on the surface of the limit joint 6. The limit bolt on the surface of the limit joint 6 can be removed, and then the rod body 1 is connected through the thread of the limit joint 6 to connect the two rod bodies 1, thereby increasing the height of the rod body 1. By arranging the rod body 1 and the limit joint 6, when the support rod faces a steel house with a larger span, the height of a single support rod may not be enough, and the height of the rod body 1 needs to be increased.

[0029] The limit joint 6 has a groove structure built in, and a limit bolt is passed through one side of the limit joint 6. The steel wire rope can be fixed by the groove structure to limit the movement of the steel wire rope, and the steel wire fixed inside the limit joint 6 can be further fixed by the passing limit bolt to limit the range of movement of the steel wire rope and enhance the stability of the support rod fixing the steel wire rope.

[0030] When the steel roof truss safety rope hanging support structure of the utility model is used, it is necessary to determine the span of the steel roof structure, prepare a suitable number of support rods according to the width, install two clamps 3 on the support rods at both ends, and install one clamp 3 on the remaining support rods, and then the support rods can be installed at equidistant lengths, and the clamps 3 of the support rods are clamped into the edge of the I-beam, so that the top plate 41 of the vise 4 fits against the bottom edge of the I-beam through the inclination shaft 42, and then start to tighten the fastening bolt 44, which rotates along the bolt so that the inclination shaft 42 and the top plate 41 at the upper end of the rotating shaft 43 gradually rise, so that the vise 4 bites into the edge of the I-beam, and the vise 4 on one side is synchronized so that the support rods are all fixed on the steel roof end. After the crossbeam is installed, the steel wire rope can be passed through. The steel wire is fixed on the fixing bolt on the surface of the rod body 1, and one is fixed in the groove of the limit joint 6. When the support rod faces a steel house with a larger span, the height of a single support rod may not be enough, and the height of the rod body 1 needs to be increased. The limit bolt on the surface of the limit joint 6 can be removed, and then the rod body 1 is connected through the threaded connection of the limit joint 6, so that the two rod bodies 1 are connected, thereby increasing the height of the rod body 1. Compared with the traditional method, after the construction is completed, it is necessary to cause certain damage to the steel structure before removing the support rod, which is time-consuming and labor-intensive. The device can be reused and can be applied to the surface of I-beams and H-beams, effectively improving construction quality and reducing construction costs.
