Advantages and features of the invention will become more apparent from the following description and from the claims. It should be further noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention. For convenience of description, the "upper" and "lower" described below are consistent with the upper and lower directions of the drawings, but this should not be construed as a limitation of the technical scheme of the present invention.
Referring to fig. 1 and 2, the structural composition of the tightness-adjustable armrest outer protective sheath of the present invention is described in detail.
Example 1
As shown in fig. 1 and 2, an outer protective sheath of handrail with adjustable elasticity, including a plurality of end to end and one side open-ended sheath units (not shown), sheath unit open end is towards handrail (not shown), and the cover is established and is set up on the handrail, every sheath unit includes inlayer rubber lining 1 and outer stereoplasm PVC protecting cover 2, outer stereoplasm PVC protecting cover free end length is greater than inlayer rubber lining free end length, for example, the two differ 50mm, outer stereoplasm PVC protecting cover 2 is close to open-ended one end and is equipped with connecting piece 3, the sheath unit passes through connecting piece 3 fastening on the handrail.
In particular, in order to better protect the stair railing, the surface material decoration of the stair railing is not damaged, and a protective sheath is sleeved outside the stair railing. The protective sheath comprises a plurality of sheath units which are connected end to end and are open at one side, the opening direction faces to the stair railing, and the sheath units comprise an inner layer structure and an outer layer structure. The inner layer adopts a soft rubber sheath, so that the abrasion to the surface of the handrail is reduced. The material is softer and has good elasticity, and can buffer the impact of tool machinery or other hard building materials on the armrests to a certain extent, thereby playing a role in protection. The outer layer adopts a flame-retardant hard PVC protecting cover. The hard material can effectively resist the collision of other objects to the handrail, and the PVC is a flame-retardant material, so that the PVC is safer than the traditional soft plastic foam, and is suitable for being used on a construction site. The PVC protecting cover is close to the open end, namely the side wall is provided with a connecting piece 3 which is detachably connected, and the connecting piece 3 can adjust the tightness of the connection between the protecting cover and the handrail.
In particular, the sheath unit has a U-shaped cross section. That is, the outer side of the outer hard PVC cover 2 adopts rounded corners, thereby preventing a constructor from touching scratch when passing.
Further, the connecting piece 3 can be an adjustable bolt and a nut which is matched with the adjustable bolt, the adjustable bolt can be detached before the armrest protecting sleeve is installed, and the adjustable bolt can be fixed by tightening the nut after the armrest protecting sleeve is installed and placed on the armrest. That is, the outer hard PVC protecting cover 2 is provided with a bolt hole at one end close to the opening, and the bolt passes through the bolt hole to lock and fix the protecting cover unit on the handrail.
Of course, in order to improve the connection efficiency between the sheath unit and the handrail, the connecting piece 3 may be a buckle, so that a protruding structure may be disposed on an end of the outer hard PVC protecting cover close to the opening.
Further, in order to better resist the collision of other objects to the handrail, the material decoration of the surface of the handrail of the stair is protected, and the inner rubber lining 1 and the outer hard PVC protecting cover 2 are connected by adopting an adhesive.
Of course, the handrail for protection can be a wooden handrail or a cast iron handrail, and can also be a handrail made of other materials. The outer protective sheath of the handrail can be used for protecting the handrail and preventing the surface of the handrail from being worn.
Example two
With continued reference to fig. 1 and 2, the present embodiment provides a construction method of an tightness-adjustable armrest outer protective sheath according to the present invention, the construction method comprising the steps of:
step one, manufacturing a sheath unit for standby in a factory, wherein the sheath unit comprises an inner layer rubber lining 1 and an outer layer hard PVC protecting cover 2 which are fixedly connected by an adhesive, and a connecting piece 3 is arranged at one end of the outer layer hard PVC protecting cover, which is close to an opening. The section of the sheath unit is U-shaped, so that the sheath unit is attractive in appearance and can prevent sharp corners from scratching the personnel who can contact the side of constructors and the like.
Step two, arranging a plurality of sheath units on the handrail towards the handrail through butt joint openings in sequence. Of course, sheath units with different sizes and different specifications can be designed according to construction requirements, so that the splicing efficiency of the sheath is improved, and meanwhile, the material consumption is reduced.
And thirdly, attaching and locking a plurality of sheath units to the handrail by adjusting the connecting piece 3, so that the whole handrail is protected, and a complete protective sheath is formed. Of course, the tightness of the protective sheath can be adjusted by adjusting the connection 3.
In summary, according to the tightness-adjustable handrail outer protection sheath and the construction method, the sheath units consisting of the inner rubber lining and the outer hard PVC protecting cover are connected end to end, and are detachably and tightly-adjustable fixedly connected outside the handrail through the connecting piece, so that the effect of protecting a finished handrail product can be achieved, paint on the outer surface of the handrail is prevented from falling off and being damaged and deformed due to collision of external force in the construction process, the condition that a bubble film is not protected in place by adopting a traditional protection method is avoided, and the repeated maintenance workload of the finished handrail is reduced. In addition, the outer protective sheath of the handrail capable of being adjusted in an elastic mode can be repeatedly recycled after being disassembled, cost is saved, and material loss is reduced.
The above description is only illustrative of the preferred embodiments of the invention and is not intended to limit the scope of the invention in any way. Any alterations and modifications made by those having ordinary skill in the art in light of the foregoing disclosure are intended to be within the scope of the following claims.
