Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a protective cover for double elevator shafts. Background Technology

[0002] In the field of building construction, the protection of various openings plays a crucial role. Its core objective is to effectively prevent workers from falling from heights due to accidents and to ensure the safety of construction workers.

[0003] In the construction process of floor slab reinforcement and concrete pouring, protecting the openings in elevator shafts is a critical task. Currently, protective covers are commonly used to cover the elevator shaft openings. However, in actual construction scenarios, when adjacent elevator shafts are located within a building, two separate protective covers are required. Because these two covers are separate, they must be hoisted one by one during the hoisting operation. This multiple-lifting process not only increases the complexity of the construction process but also significantly reduces overall construction efficiency, negatively impacting the project schedule. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem of low construction efficiency caused by the need to set up and hoist two independent protective covers one by one in the process of protecting adjacent elevator shaft openings in the prior art, and to provide a double elevator shaft protective cover.

[0005] This utility model provides a double elevator shaft protective cover, comprising:

[0006] Two protective components are arranged side by side. The protective components have a conical structure and include a base frame. The shape and size of the base frame of the two protective components are respectively adapted to the shape and size of the corresponding elevator shaft.

[0007] The first link, with its two ends respectively connected to the vertices of the two protective components;

[0008] The second link has two ends connected to the midpoint of the first link and the corresponding bottom frame, respectively.

[0009] The bottom of the base frame is provided with a vertical member, and a bolt is provided on the vertical member. The bolt can be rotated to move the end of the bolt away from or close to the vertical member. The end of the bolt is used to abut against the template inside the elevator shaft.

[0010] This utility model provides a double elevator shaft protective cover. The bottom frame is used to align with the edge of the corresponding elevator shaft on the working floor. A first connecting rod connects the two protective components together, allowing the lifting point to be set on the first connecting rod for simultaneous hoisting of both components. A second connecting rod strengthens the connection between the protective component and the first connecting rod, improving the rigidity and stability of the entire device during placement and preventing deformation during hoisting or actual use. The vertical component and the bolt prevent the protective component from sliding relative to the elevator shaft after installation, providing stable fixation. The distance between the bolt end and the vertical component can be changed by rotating the bolt, allowing the end to move away from or closer to the vertical component. During the installation of the protective cover, the bolt is adjusted to move the end towards the template inside the elevator shaft, ultimately ensuring a tight fit between the vertical component and the template inside the elevator shaft. This design facilitates the installation, fixation, and subsequent disassembly of the protective cover.

[0011] This application enables a one-time hoisting operation by connecting the two protective components into a whole, thereby simultaneously completing the protection work of two elevator shafts and effectively improving construction efficiency.

[0012] Both the first connecting rod and the second connecting rod can be made of steel bars, steel pipes or aluminum profiles.

[0013] Preferably, the protective component further includes several main keels, several secondary keels, and a reinforcing frame; one end of each main keel converges and connects together to form the apex of the protective component, and the other end of each main keel is evenly distributed along the bottom frame and connected to the bottom frame; both ends of each secondary keel are connected to the main keel and the bottom frame respectively; the reinforcing frame is located between the bottom frame and the apex and is used to connect all the secondary keels together.

[0014] The bottom frame, the main keel, the secondary keel, and the reinforcing frame can all be made of stainless steel, aluminum profiles, engineering plastics, or steel bars.

[0015] Preferably, the bottom frame, the main keel, the secondary keel, and the reinforcing frame are all made of steel reinforcement. Compared with other materials, steel reinforcement is more readily available on the construction site. The protective components can be made using scrap steel reinforcement, thus effectively reducing manufacturing costs.

[0016] Preferably, both the first connecting rod and the second connecting rod are steel pipes. Compared with reinforcing bars, steel pipes exhibit superior cross-sectional stiffness; compared with aluminum profiles, steel pipes have a cost advantage.

[0017] Preferably, the connection between the first connecting rod and the protective component is detachable, and the connection between the second connecting rod and the base frame is also detachable. This design allows the protective cover to be stored by detaching the two protective components from the first and second connecting rods respectively. Then, the two protective components can be stacked for storage, effectively saving storage space. The detachable connection can be a bolt connection, a pin connection, or a snap-fit ​​connection.

[0018] Preferably, the first connecting rod is provided with two lifting rings, which are located on both sides of the midpoint of the first connecting rod.

[0019] Preferably, a fence is connected above the base frame. The main function of the fence is to prevent personnel from entering the area above the protective component and to prevent personnel from stepping on the protective component, thereby effectively improving the safety of on-site construction.

[0020] The fence is equipped with web members that connect the upper and lower bars. The web members can be uprights, diagonal bars, or arched bars.

[0021] Preferably, the fence includes web members, which are continuous arched structures.

[0022] Preferably, the distance between the vertex of the protective component and the corresponding bottom frame is 400mm-800mm.

[0023] Preferably, the midpoints of two adjacent second links are connected by a third link. The inclusion of this third link further enhances the rigidity and stability of the entire device.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This utility model provides a double elevator shaft protective cover. By connecting the two protective components into a whole, a one-time hoisting operation can be achieved, thereby completing the protection work of two elevator shafts at the same time and effectively improving construction efficiency.

[0041] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0042] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0043] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0044] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0045] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0046] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

Specifically, the vertical member 105 can be made of a section of angle steel, and its top is welded to the base frame 101. The bolts 1051 are connected to the bottom of the vertical member 105 through screw holes. After the protective cover is installed on the corresponding elevator shaft, the vertical member 105 will be positioned inside the elevator shaft template. By rotating the bolts 1051, the ends of the bolts 1051 can move closer to or away from the template corresponding to the elevator shaft. The vertical member 105... Figure 2 Not shown in the image.

Specifically, the spacing between two adjacent secondary keels 103 is 80mm-120mm.

[0054] When the shape of the base frame 101 is rectangular or other polygonal, the other end of each main keel 102 in each protective component 1 is connected to the midpoint of each side segment of the base frame 101.

[0055] In an optional embodiment, the bottom frame 101, main keel 102, secondary keel 103, and reinforcing frame 104 can all be made of steel reinforcement.

The secondary keel 103 is made of Grade III ribbed steel bars with a diameter range of 6mm-8mm. The bottom frame 101 is made by welding four sections of steel reinforcement together end to end.

[0056] In an optional embodiment, both the first connecting rod 2 and the second connecting rod 3 can be steel pipes. Specifically, the diameter of the steel pipe can be 60mm-100mm, and the specific diameter can be 60mm, 70mm, 80mm, 90mm, or 100mm. The wall thickness of the steel pipe can be 1.5mm-3mm.

[0057] In an optional embodiment, the connection between the first link 2 and the protective member 1 can be a detachable connection, and the connection between the second link 3 and the bottom frame 101 can be a detachable connection.

[0059] In an optional embodiment, a fence 106 may be connected above the base frame 101. Specifically, the fence 106 is perpendicular to the plane of the base frame 101. The fence 106 is... Figure 2 Not shown in the image.

[0060] In an optional embodiment, the fence 106 may include web members, which are continuous arched structures. Specifically, the height of the fence 106 is 0.4m-0.8m. The web members may be made of round steel with a diameter of 6mm.

[0063] Compared to a single, independent protective cover, the double elevator shaft protective cover of this application combines two protective covers into one, making the protective cover more stable and preventing the situation where a single, independent protective cover would warp due to being stepped on or other reasons, thus failing to provide adequate protection.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
