Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a horizontal protective device for an elevator shaft. Background Art

[0002] According to Section 4.2.3 of the JGJ80-2016 "Technical Specifications for Safety of Construction Height Work," before entering the elevator installation process, a horizontal safety net should be installed every 10 meters and no more than two floors in the shaft. Isolation and protection facilities should be installed above the construction floor in the elevator shaft.

[0003] Existing elevator shaft horizontal protection often involves installing a circle of steel pipes on the inner wall of the shaft with a horizontal net suspended in the middle. This requires manual entry and removal before elevator installation, which is quite dangerous. This type of protection uses a large amount of steel pipe, which must be cut to the shaft dimensions, resulting in waste.

[0004] Problems with existing technologies:

[0005] Due to the differences in the shafts, steel pipes need to be cut, which is time-consuming and labor-intensive. The cut steel pipes are not easy to return, and the steel pipe fasteners used for protection generate rental fees every day. The multi-layered use of the original horizontal nets increases costs, and it is difficult to remove them later. The steel pipes and fasteners protrude from the shaft wall, posing a risk of secondary injury.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0023] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0024] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0025] like Figures 1 to 2 As shown, a horizontal protection device for an elevator shaft according to a preferred embodiment of the present invention includes multiple single-layer soft protection structures and hard protection structures; each single-layer soft protection structure includes multiple eyelet expansion bolts 3, steel wire ropes 2 and a single-layer safety net 1; multiple eyelet expansion bolts 3 are arranged on the concrete walls 7 and concrete beams 8 around the elevator shaft; the steel wire rope 2 is passed through the eyelets of multiple eyelet expansion bolts 3 to form a closed loop of steel wire rope loop; the single-layer safety net 1 is hung on the steel wire rope loop; the hard protection structure includes multiple steel pipes 5 and multiple multi-layer boards 6; multiple steel pipes 5 are cross-arranged between the concrete wall 7 and the concrete beam 8 and between the concrete wall 7 and the concrete wall 7; multiple multi-layer boards 6 are fully spread on the multiple steel pipes 5.

[0026] In some embodiments, a soft protection structure is provided every two floors, and the distance between the two soft protection structures is no more than 10 meters. This design is mainly for safety, to avoid excessive acceleration in case an object or operator falls due to too large a distance.

[0027] In some embodiments, each soft protective structure also includes an oil wire rope lock buckle 4, which is used to lock and fix the two ends of the steel wire rope 2 in the eye rings of multiple eye ring expansion bolts 3, and the oil wire rope lock buckle 4 is arranged on one side of the elevator door. This design makes it more convenient to install and remove the oil wire rope lock buckle 4.

[0028] In some embodiments, a hard protective structure is provided at the motor shaft on the first floor, and the side of the hard protective structure close to the elevator door is lower than the side away from the elevator door. The hard protective structure is mainly used to prevent small objects from falling from the upper floor to the lower floor. The safety net cannot catch them, but the hard protective structure can block them. In addition, the dropped objects will roll along the slope to the side of the elevator door for easy cleaning.

[0029] In some embodiments, a hard protective structure is provided every two single-layer soft protective structures, and the distance between each hard protective structure and the single-layer soft protective structure is no more than two floors and no more than 10 meters.

It is best that half of the distance between adjacent eyelet expansion bolts 3 is less than or equal to 500 mm.

[0031] See also Figure 2 In some embodiments, the spacing between the multiple steel pipes 5 of the hard protective structure is less than or equal to 500 mm.

[0032] In some embodiments, the elevator shaft horizontal protection device also includes a double-layer soft protection structure (not shown). The double-layer soft protection structure is installed two meters above the bottom of the elevator shaft. In particular, buildings with multi-story basements must be equipped with a double-layer soft protection structure. The double-layer soft protection structure is basically the same as the single-layer structure, except that it uses a double-layer safety net hung on the wire rope loop. The double-layer safety net can be used by stacking two single-layer safety nets 1 together.

[0033] In summary, the horizontal protection device of the elevator shaft of the present invention has the following advantages: the horizontal protection device of this scheme has a simple structure and is easy to install and dismantle. After dismantling, the damage to the wall is small and the wall is easy to restore; the wire rope and the net can be reused, and there is no need to consume steel pipe fasteners and other materials, thereby reducing material waste; the locking end is located at the elevator door, which is convenient for later unlocking and dismantling; there is no increase in the rental cost of materials such as steel pipe fasteners during construction and use; the soft net has no protruding hard objects and will not cause secondary injuries, which can significantly reduce secondary injuries caused by falling from the hole.
