Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hoisting hole protection device. Background Art

[0002] During the construction process, it is often necessary to transport construction materials or construction equipment from the lower building to the upper building. Therefore, a lifting hole is usually left on the floor of the building to facilitate lifting the inspected materials and construction equipment from the lifting hole to the upper building. In order to prevent workers from falling from the hole, protective fences are usually placed around the lifting hole, and danger warning signs are placed on the protective fences.

[0003] In the prior art, a protective fence is formed by installing a customized protective mesh on a mobile support and the protective fence is arranged around the circumference of the hoisting hole. In some protective fences, in order to maintain the stability of the protective fence, the bottom of the mobile support is usually covered with a heavy object to reduce the possibility of movement and tipping of the mobile support.

[0004] However, the protective fence in the above-mentioned prior art is still prone to deviation and collapse when subjected to a large impact, causing safety hazards. Utility Model Content

[0005] In view of this, the utility model provides a hoisting hole protection device to solve the problem that when the protective fence is subjected to a large impact, it will deviate and topple over, causing safety hazards.

[0006] The utility model provides a hoisting hole protection device, comprising: embedded parts, which are multiple and spaced apart around the circumference of the hoisting hole, the embedded parts are preset in the concrete structure of the floor and the top is exposed from the upper side of the floor; a fence, comprising a plurality of protection frames which are connected end to end in sequence and are jointly arranged around the circumference of the hoisting hole, the protection frames comprising a plurality of columns, a waist cross bar and a top cross bar, the bottoms of the plurality of columns are respectively connected to the tops of the corresponding embedded parts, the waist cross bar is connected to the middle of the column, and the top cross bar is connected to the top of the column.

[0007] Beneficial effect: By setting embedded parts preset in the floor slab, and then connecting the protective frame with the embedded parts through columns to form a fence, the fence is fixedly set around the lifting hole. The whole fence structure is firm and stable. Moreover, since it is directly connected to the floor slab through the embedded parts, the fence is not easy to topple or move when subjected to external force, which effectively improves the safety of the operators.

[0008] In an optional embodiment, the waist cross bar and the top cross bar are both connected to the upright posts via fasteners.

[0009] Beneficial effects: Since the waist cross bar and the top cross bar are connected to the columns by fasteners, the entire fence is assembled in a detachable connection manner, which is convenient for transportation and storage. In addition, all components except the embedded parts can be disassembled and reused. The embedded parts themselves are completely embedded in the floor slab during the secondary pouring of the floor slab after the lifting work is completed, avoiding obstacles to normal walking on the floor slab.

[0010] In an optional embodiment, the embedded part is a channel steel, and the column is connected to the top of the embedded part via a fastener.

[0011] Beneficial effect: By using channel steel as embedded parts, on the one hand, the structural strength is guaranteed; on the other hand, since channel steel is a common building material with high replaceability and low cost, the construction difficulty and cost are effectively reduced.

[0012] In an optional embodiment, it also includes a plurality of reinforcement members arranged on the inner side of the fence, wherein the reinforcement members are arranged between two adjacent protective frames, wherein the first end of the reinforcement member is connected to the waist cross bar of one of the protective frames, and the second end of the reinforcement member is connected to the waist cross bar of another of the protective frames.

[0013] Beneficial effect: By arranging reinforcements on the inner side of the fence and making the reinforcements support the waist cross bars of any two adjacent protective frames respectively, the structural strength of the fence is improved, and a supporting structure for each protective frame is formed on the inner side of the fence, further reducing the possibility of the fence tipping toward the lifting hole.

[0014] In an optional embodiment, the reinforcement member includes a supporting portion and two connecting portions respectively arranged at both ends of the supporting portion, the supporting portion is rod-shaped and the angles between the supporting portion and the waist cross bars of two adjacent protective frames are acute angles, and the connecting portion has a snap-fitting groove, which is adapted to the cross-sectional shape of the corresponding waist cross bar.

[0015] Beneficial effect: By setting an acute angle between the support part and the waist cross bars of two adjacent protective frames, a stable triangular support structure is formed between the support part and the two waist cross bars, and then the support part is connected to the two waist cross bars through a connecting part with a clamping groove to avoid the separation of the reinforcement and the protective frame, so that each reinforcement can firmly connect and support each protective frame from the inside of the fence. Each protective frame is not easy to topple toward the direction of the lifting hole, nor is it easy to move independently. In the event that the connection between the column and the embedded part of a certain protective frame fails accidentally, the position and posture of the protective frame can still be maintained through the connection of the reinforcement, thereby providing safety protection for the operators before the fence is repaired.

[0016] In an optional embodiment, the cross-sectional outer contours of the uprights, waist crossbars and top crossbars are all rectangular.

[0017] Beneficial effects: Since the cross-sectional outer contours of the uprights, waist cross bars and top cross bars are all rectangular, each component has sufficient contact area when connected, preventing each component from rotating or displacing, thereby affecting the stability of the entire protective frame. At the same time, since the cross-sectional shape of the waist cross bar is adapted to the snap-in groove, the waist cross bar with a rectangular contour cooperates with the snap-in groove, so that the reinforcement is more firmly connected to the corresponding waist cross bar.

[0018] In an optional embodiment, the connecting portion is detachably connected to the waist cross bar via a fastener.

[0019] Beneficial effects: The connection rod further reduces the possibility of the reinforcement being separated from the waist crossbar, thereby improving the stability of the structure. In addition, the fasteners are used to achieve a detachable connection, making the structure easy to install and disassemble, and it can be recycled.

[0020] In an optional embodiment, a protective mesh is further included, and the protective mesh is detachably connected to the protective frame.

[0021] Beneficial effect: The protective mesh is set on the protective frame, which further reduces the risk of workers falling through the protective frame, and also prevents the possibility of other objects falling into the lifting hole through the gaps in the protective frame.

[0022] In an optional embodiment, a fixing frame is provided on the connecting portion, and the fixing frame includes a first structural rod and two second structural rods arranged on the first structural rod. When the protective mesh is installed on the protective frame, the first structural rod is located on the side of the protective mesh away from the protective frame, and the two second structural rods pass through different mesh holes on the protective mesh and are respectively connected to the connecting portion by fasteners.

[0023] Beneficial effect: By setting up a fixing frame, the protective mesh can be quickly fixed to the protective frame, and the two second structural rods of the fixing frame pass through different mesh holes of the protective mesh, and then cooperate with the first structural rod to press the protective mesh to fix the protective mesh. The operator operates the fasteners through the mesh holes of the protective mesh to connect the fixing frame to the connecting part. Compared with the method of wrapping the protective mesh on the protective frame with wire, the operation is simpler and more labor-saving. At the same time, by setting the fixing frame on the connecting part, since the fixing frame simplifies the installation of the protective mesh, the operator will actively use the fixing frame to fix the protective mesh when installing the protective mesh. Therefore, to a certain extent, it avoids the situation where the operator fails to install the reinforcement on the protective frame due to illegal simplification of operation or forgetfulness.

[0024] In an optional embodiment, a plurality of mesh hooks are provided on the waist cross bar, and the mesh hooks include a bearing portion and a limiting portion, the bearing portion is arranged in a horizontal direction, and the limiting portion is located at one end of the bearing portion away from the waist cross bar and extends obliquely upward.

[0025] Beneficial effect: By setting the mesh hook, it is convenient to pre-position the protective mesh when installing it, and it replaces the fixed frame to bear part of the weight of the protective mesh, preventing the protective mesh from detaching from the protective frame, thereby improving the structural reliability.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0034] During construction, it is usually necessary to transport equipment or building materials from the lower building to the upper building. One way is to directly lift the equipment and building materials from the outside of the building to the window of the target floor, but this lifting method is greatly affected by the weather and is not suitable for buildings with complex external structures or large floor areas. Another way is to set lifting holes on the floor slab of the building and directly transport the equipment or building materials through the lifting holes inside the building.

[0035] In the related art, in order to reduce the risk of workers falling near the hoisting hole, a fence 200 is generally set around the hoisting hole and a warning sign is hung, and the bottom of the fence 200 is pressed down with a heavy object to fix the fence 200. However, the fence 200 fixed by this method is not stable and is prone to fall down when subjected to external forces such as impact, posing a safety hazard.

[0036] The present application proposes a method of setting an embedded part 100 in the concrete structure of a floor slab and fixing the structure to the embedded part 100, so as to obtain a hoisting hole protection device with good impact resistance and high safety.

[0037] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0038] According to an embodiment of the utility model, a lifting hole protection device is provided, including: embedded parts 100, having multiple and spaced distribution around the lifting hole, the embedded parts 100 are preset in the concrete structure of the floor and the top is exposed from the upper side of the floor; a fence 200, including multiple protection frames 201 connected end to end and jointly arranged around the lifting hole, the protection frame 201 includes multiple columns 2011, waist cross bars 2012 and top cross bars 2013, the bottoms of the multiple columns 2011 are respectively connected to the tops of the corresponding embedded parts 100, the waist cross bars 2012 are connected to the middle of the columns 2011, and the top cross bars 2013 are connected to the tops of the columns 2011.

[0039] In this embodiment, by setting the embedded parts 100 preset in the floor slab, and then connecting the protective frame 201 with the embedded parts 100 through the columns 2011 to form the fence 200, the fence 200 is fixedly set in the circumference of the lifting hole. The structure of the entire fence 200 is firm and stable. In addition, since it is directly connected to the floor slab through the embedded parts 100, the fence 200 is not easy to topple or shift when subjected to external force, which effectively improves the safety of the operators.

[0040] It should be noted that the present embodiment does not limit the specific form of the embedded part 100, and the embedded part 100 may be an angle steel or other shapes and structures. The embedded part 100 is embedded in the floor slab during the pouring process of the floor slab, and after the hoisting construction is completed, it is buried in the second pouring floor slab structure as the floor slab is poured.

[0041] Specifically, the shape of the fence 200 is adapted to the shape of the hoisting hole. Exemplarily, the hoisting hole is rectangular. Accordingly, the fence 200 includes four protective frames 201, and each protective frame 201 is parallel to the corresponding side of the hoisting hole. In the protective frame 201, the column 2011 can be connected to the embedded part 100 by fasteners. In some embodiments not shown, the column 2011 can also be connected to the embedded part 100 by welding, plugging, etc. In addition, the connection between the column 2011, the waist crossbar 2012 and the top crossbar 2013 can be achieved by fasteners, or by welding, plugging, etc. The fasteners can include parts with fastening and connecting functions such as screws and bolts.

[0042] In one embodiment, the waist cross bar 2012 and the top cross bar 2013 are both connected to the column 2011 by fasteners.

[0043] In this embodiment, since the waist cross bar 2012 and the top cross bar 2013 are connected to the column 2011 by fasteners, the entire fence 200 is assembled in a detachable connection manner, which is convenient for transportation and storage. In addition, all components except the embedded parts 100 can be disassembled and reused. The embedded parts 100 themselves are completely embedded in the floor slab during the secondary pouring of the floor slab after the lifting work is completed, so as to avoid obstruction to normal walking on the floor slab.

[0044] In one embodiment, the embedded component 100 is a channel steel, and the column 2011 is connected to the top of the embedded component 100 through a fastener.

[0045] In this embodiment, by using channel steel as the embedded part 100, on the one hand, the structural strength is guaranteed, and on the other hand, since the channel steel is a common building material, it is highly replaceable and low in cost, which effectively reduces the construction difficulty and construction cost.

[0046] In one embodiment, it also includes a plurality of reinforcement members 300 disposed on the inner side of the fence 200 , the reinforcement member 300 is disposed between two adjacent protective frames 201 , the first end of the reinforcement member 300 is connected to the waist cross bar 2012 of one protective frame 201 , and the second end is connected to the waist cross bar 2012 of another protective frame 201 .

[0047] Specifically, this embodiment does not limit the specific form of the reinforcement 300. The reinforcement 300 can be a rod-shaped member that is placed between the waist cross bars 2012 of two adjacent protective frames 201. In some embodiments not shown, the reinforcement 300 can also be a part of other shapes such as angle iron.

[0048] In this embodiment, by setting a reinforcement 300 on the inner side of the fence 200, and making the reinforcement 300 support the waist cross bars 2012 of any two adjacent protective frames 201 respectively, the structural strength of the fence 200 is improved, and a supporting structure for each protective frame 201 is formed on the inner side of the fence 200, thereby further reducing the possibility of the fence 200 tipping toward the lifting hole.

[0049] In one embodiment, the reinforcement member 300 includes a support portion 301 and two connecting portions 302 respectively arranged at both ends of the support portion 301. The support portion 301 is rod-shaped and the angles between it and the waist cross bars 2012 of two adjacent protective frames 201 are both acute angles. The connecting portion 302 has a snap-in groove 3021, and the snap-in groove 3021 is adapted to the cross-sectional shape of the corresponding waist cross bar 2012.

[0050] In this embodiment, by setting an acute angle between the support part 301 and the waist cross bars 2012 of two adjacent protective frames 201, a stable triangular support structure is formed between the support part 301 and the two waist cross bars 2012, and then the support part 301 is connected to the two waist cross bars 2012 through a connecting part 302 with a snap-in groove 3021, so as to avoid the separation of the reinforcement 300 and the protective frame 201, so that each reinforcement 300 can firmly connect and support each protective frame 201 from the inside of the fence 200, and each protective frame 201 is not easy to topple toward the direction of the lifting hole, nor is it easy to move independently. In addition, in the event that the connection between the column 2011 of a protective frame 201 and the embedded part 100 fails accidentally, the position and posture of the protective frame 201 can still be maintained through the connection of the reinforcement 300, thereby providing safety protection for the operating personnel before the fence 200 is repaired.

[0051] In one embodiment, the cross-sectional outer contours of the upright column 2011 , the waist cross bar 2012 and the top cross bar 2013 are all rectangular.

[0052] In this embodiment, since the outer contours of the cross-sections of the upright column 2011, the waist cross-bar 2012, and the top cross-bar 2013 are all rectangular, each component has a sufficient contact area when connected, preventing the components from rotating or displacing and thus affecting the stability of the entire protective frame 201. At the same time, since the shape of the clamping groove 3021 matches the cross-sectional shape of the waist cross-bar 2012, the reinforcing member 300 is more firmly connected to the corresponding waist cross-bar 2012 through the cooperation of the waist cross-bar 2012 with a rectangular contour and the clamping groove 3021.

[0053] In one embodiment, the connecting portion 302 and the waist cross-bar 2012 are detachably connected by fasteners.

[0054] In this embodiment, the connecting rod further reduces the situation where the reinforcing member 300 is separated from the waist cross-bar 2012, improving the structural stability. In addition, the detachable connection is achieved through fasteners, making the structure simple to install and拆卸, and it can be recycled.

[0055] In one embodiment, it further includes a protective mesh sheet (not shown in the figure), and the protective mesh sheet is detachably connected to the protective frame 201.

[0056] In this embodiment, the protective mesh sheet is arranged on the protective frame 201, further reducing the situation where the operating personnel fall through the protective frame 201 and preventing other objects from falling into the hoisting hole through the gaps on the protective frame 201.

[0057] In one embodiment, a fixing frame 400 is provided on the connecting portion 302. The fixing frame 400 includes a first structural rod 401 and two second structural rods 402 arranged on the first structural rod 401. When the protective mesh sheet is installed on the protective frame 201, the first structural rod 401 is located on the side of the protective mesh sheet away from the protective frame 201, and the two second structural rods 402 pass through different mesh holes on the protective mesh sheet and are respectively connected to the connecting portion 302 by fasteners.

[0058] Specifically, the first structural rod 401 and the second structural rod 402 are integrally arranged and form a "匚"-shaped frame.

[0059] In this embodiment, by providing a fixing frame 400, the protective mesh can be quickly fixed to the protective frame 201. The two second structural rods 402 of the fixing frame 400 pass through different mesh holes of the protective mesh, and the first structural rod 401 presses the protective mesh to fix the protective mesh. The operator operates the fasteners through the mesh holes of the protective mesh to connect the fixing frame 400 with the connecting part 302. Compared with the method of wrapping the protective mesh around the protective frame 201 with wire, the operation is simpler and more labor-saving. At the same time, by providing the fixing frame 400 on the connecting part 302, since the fixing frame 400 simplifies the installation of the protective mesh, the operator will actively use the fixing frame 400 to fix the protective mesh when installing the protective mesh. Therefore, to a certain extent, it is avoided that the operator fails to install the reinforcement 300 on the protective frame 201 due to illegal simplification of operations or forgetfulness.

[0060] In one embodiment, a plurality of mesh hooks 500 are provided on the waist cross bar 2012, and the mesh hooks 500 include a bearing portion 501 and a limiting portion 502. The bearing portion 501 is arranged in the horizontal direction, and the limiting portion 502 is located at one end of the bearing portion 501 away from the waist cross bar 2012 and extends obliquely upward.

[0061] In this embodiment, by providing a mesh hook 500, it is convenient to pre-position the protective mesh when installing it, and replace the fixed frame 400 to bear part of the weight of the protective mesh, preventing the protective mesh from detaching from the protective frame 201, thereby improving the structural reliability.

[0062] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
