Description

Technical Field

[0001] The utility model relates to a temporary stair handrail used in building construction. Background Art

[0002] During the construction process, the handrails on the side of the stairs need to be installed after the interior decoration is almost completed and the stairs have been tiled. Before this, there are no handrails on the side of the stairs for protection, which poses certain safety hazards.

[0003] Therefore, in order to meet the needs of safe construction, it is necessary to install temporary handrails on the sides of the stairs in the prior art. The existing temporary handrails are mainly steel structures and are installed by bolt fixing. It is necessary to drill holes in the stair steps, and the steps need to be repaired later, which is troublesome. The installation is also troublesome, and it cannot be installed if the angle is not right.

[0004] To this end, we designed a temporary stair handrail for construction that is more versatile and has fewer openings. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a temporary stair handrail for building construction which has stronger versatility and fewer openings.

[0006] The utility model is realized by the following technical solutions:

[0007] A temporary stair handrail for construction includes a column, a base is arranged at the bottom of the column, a connecting hole is vertically penetrated at the top of the base, a supporting component is installed through the column, more than one supporting component is provided, and can slide along the axial direction of the column and can also rotate coaxially along the column, a safety rope is assembled through the supporting component, and is intercepted on the outside of the stairs by the safety rope.

[0008] Preferably, the supporting assembly comprises a sleeve, an axle rod and a sleeve are fixedly provided at the outer wall of the sleeve, the axle rod and the sleeve are on the same diameter line of the sleeve, a wire winding drum is rotatably mounted on the axle rod, a wire winding groove is provided on the outside of the wire winding drum, a first screw is cooperated between the wire winding drum and the axle rod, a rotating rod is rotatably mounted through the sleeve, a second screw is cooperated between the sleeve and the rotating rod, a through groove is radially penetrated at the outer wall of the rotating rod, a wire fixing plate is inserted in the through groove, the wire fixing plate slides laterally along the through groove, a sliding groove penetrating the through groove is provided at the outer wall of the rotating rod, a third screw is cooperated through the sliding groove, the third screw is screwed into the wire fixing plate, one end of the safety rope is fixed in the winding groove, the remaining part is wound in the winding groove, and the other end of the safety rope is fixed by the wire fixing plate after being pulled out.

[0009] Preferably, rubber ball heads are embedded on the outside of the shaft rod and the rotating rod.

[0010] Preferably, the wire fixing plate is provided with a first wire threading hole and a second wire threading hole, and the first wire threading hole and the second wire threading hole are respectively arranged above and below the rotating rod. On the wire fixing plate, a third wire threading hole is arranged above the first wire threading hole, and a fourth screw that is inserted into the third wire threading hole is screwed into the top of the wire fixing plate. The safety rope passes through the first wire threading hole, passes through the second wire threading hole after being bent, and then passes around the winding drum, and finally passes through the third wire threading hole. The fourth screw is screwed down to fix the safety rope.

[0011] Preferably, the safety rope is an inelastic hemp rope or a steel wire rope.

[0012] Preferably, a plurality of locking grooves are annularly distributed on the outer wall of the shaft, and the first screw is screwed into the locking groove.

[0013] The beneficial effects of the utility model are:

[0014] Advantage 1: This device can meet the temporary protection needs of stairs with different inclinations and is more versatile. During installation, there is no need to drill holes in the stair steps, thus avoiding the cracking of the stair steps. Only a small number of holes need to be drilled on each transfer platform to fix the columns, making later repairs relatively simple.

[0015] Advantage 2: This device uses a safety rope as lateral protection. While effectively preventing people from falling from the side of the stairs, the safety rope can also be quickly removed when carrying long objects, providing construction convenience.

[0016] Advantage three: the safety rope can be wound on the winding drum under normal conditions, which makes the storage volume of the equipment smaller, more lightweight, easier to load, and reduces transportation costs. BRIEF DESCRIPTION OF THE DRAWINGS

A safety rope 3 is assembled through the supporting component 2 and is intercepted on the outside of the stairs by the safety rope 3.

[0028] In this embodiment, two supporting components 2 are provided.

[0029] See also Figure 2 , Figure 3 and Figure 4 As shown, the support assembly 2 includes a sleeve 201, an axle rod 202 and a sleeve 203 are fixedly provided on the outer wall of the sleeve 201, the axle rod 202 and the sleeve 203 are on the same diameter line of the sleeve 201, a winding drum 204 is rotatably mounted on the axle rod 202, a winding groove 205 is provided on the outside of the winding drum 204, a first screw 206 is matched between the winding drum 204 and the axle rod 202, a rotating rod 207 is rotatably mounted through the sleeve 203, a second screw 208 is matched between the sleeve 203 and the rotating rod 207, A through slot 209 is radially penetrated at the outer wall of the rotating rod 207, and a fixing plate 210 is inserted into the through slot 209. The fixing plate 210 slides laterally along the through slot 209. A sliding slot 211 penetrating the through slot 209 is provided on the outer wall of the rotating rod 207. A third screw 212 is cooperated with the sliding slot 211. The third screw 212 is screwed into the fixing plate 210. One end of the safety rope 3 is fixed in the winding groove 205, and the remaining part is wound in the winding groove 205. The other end of the safety rope 3 is pulled out and fixed through the fixing plate 210.

[0030] A fifth screw 555 is provided between the pipe sleeve 201 and the column 1 .

[0031] In the above technical solution, the rotation angle of the rotating rod 207 is adjusted according to the inclination of the stairs, so that the fixing plate 210 is in an inclined state, so that after the safety rope 3 is fixed by the fixing plate 210, the safety rope 3 located between the two supporting components 2 is parallel to the stairs.

[0032] In the above technical solution, the wire winding drum can slide along the shaft rod 202 and be reasonably adjusted according to the edge position of the stairs, and the wire fixing plate 210 can also slide and adjust.

[0033] See also Figure 2 As shown, rubber ball heads 232 are embedded on the outside of the shaft rod 202 and the rotating rod 207 .

The safety rope 3 passes through the first threading hole 221, passes through the second threading hole 222 after being bent, and then passes around the winding drum 204, and finally passes through the third threading hole 223. The fourth screw 224 is screwed down and fixes the safety rope 3.

[0036] In the above technical solution, after being coiled, the safety rope 3 forms a structure of two strands at the top and one strand at the bottom, thereby increasing the protective performance.

[0037] The safety rope 3 is an inelastic hemp rope.

[0038] Hemp rope is low cost, strong, and can be easily coiled on a reel when not in use.

[0039] See also Figure 2 As shown, a plurality of locking grooves 299 are distributed in an annular manner on the outer wall of the shaft rod 202 , and the first screws 206 are screwed into the locking grooves 299 .

[0040] The locking groove 299 can prevent the winding drum from rotating after the first screw 206 is pushed in, thereby increasing the protection stability of the device.
