Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a building construction anti-falling device and a horizontal well. Background Art

[0002] During the pouring process of concrete high-rise buildings, horizontal holes such as elevator shaft holes and other floor holes are reserved. Horizontal holes are key areas for construction safety control and are prone to falling accidents during construction. The protection of horizontal holes usually uses multiple horizontal bars to block the door openings. In this installation method, the spacing between adjacent horizontal bars is large.

[0003] In the related technology, there are anti-fall nets using flexible mesh structures, such as the patent application with publication number "CN220487172U", in which a flexible mesh structure is used as the protective body over a large area. The flexible mesh structure deforms greatly when subjected to a large impact and has insufficient impact resistance, posing certain safety hazards. Summary of the invention

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the first aspect of the utility model provides a construction anti-falling device;

[0006] A second aspect of the utility model provides a horizontal well.

[0007] In view of this, according to the first aspect of the utility model, a falling prevention device for construction is proposed, comprising: an falling prevention component, the falling prevention component comprising two folding parts, the two folding parts are hinged to each other; a pre-embedded frame, the pre-embedded frame encloses the folding mesh frame, the pre-embedded frame is used to be fixedly connected to the well wall of a horizontal tunnel; at least two elastic connectors, one end of at least two elastic connectors are respectively connected to the two folding parts, and the other end of at least two elastic connectors are respectively connected to the pre-embedded frame.

[0008] In this technical solution, the anti-fall assembly includes two folding parts hinged to each other, and the two folding parts can rotate relative to each other to be folded, that is, the two folding parts can be hinged to each other to change the angle between the two folding parts.

[0009] Specifically, when the anti-fall component is not subjected to a falling impact, the two folding parts of the anti-fall component are horizontal, that is, when the anti-fall component is not subjected to an impact, the angle θ1 between the two folding parts ranges from 170° to 190°.

[0010] When a construction worker or an object accidentally falls onto the anti-falling component, the upper surface of the anti-falling component is impacted by the fall, and the angle between the two folded parts becomes smaller, that is, the two folded parts fold to cushion the construction worker or the object. When the anti-falling component is impacted, the angle θ2 between the two folded parts is in the range of 150° to 120°.

[0011] In this technical solution, the embedded frame can be embedded in the wall of the horizontal hole, so as to fix the anti-fall device for construction on the horizontal hole. The embedded frame is enclosed on the outside of the anti-fall component, that is, the enclosed area of ​​the embedded frame is larger than the area of ​​the two folding parts of the anti-fall component. When the embedded frame is enclosed on the outside of the anti-fall component, there is a large gap between the embedded frame and the anti-fall component, ensuring that the anti-fall component will not contact and interfere with the embedded frame, so that the two folding parts in the anti-fall component can be freely folded when impacted to buffer the falling objects.

[0012] In this technical solution, the elastic connector is used to connect the anti-falling component and the embedded frame, the number of the elastic connectors is at least two, each of the two folding parts in the anti-falling component is connected to one end of at least one elastic connector, and the other end of the elastic connector is connected to the inner wall of the embedded frame. The elastic connector is a tensile elastic structure, and when the anti-falling component is folded by impact, the elastic connector is in a stretched state.

[0013] Specifically, the number of elastic connectors is 2N, wherein N elastic connectors are connected between one of the two folding parts and the embedded frame, and the other N elastic connectors are connected between the other folding part and the embedded frame.

[0014] It should be noted that the anti-fall device for construction in the present application is an anti-fall component for anti-fall buffering, which is buffered by folding two folding parts hinged to each other and the stretching elastic force of the elastic connector, without the need to set a large amount of flexible material. When construction workers fall, it can not only provide a better buffering effect, but also prevent the finer fibers of the flexible material from cutting the construction workers, and improve the impact resistance and durability of the anti-fall component.

[0015] In the technical solution of the present application, the anti-fall device for construction includes an embedded frame fixed on the wall of a horizontal hole, and an anti-fall component enclosed by the embedded frame, the anti-fall component and the embedded frame are connected by an elastic connector, and the anti-fall component includes two mutually hinged folding parts. When a construction worker or an object falls on the anti-fall component, the two folding parts in the anti-fall component fold, and the elastic connector connected to the two folding parts is stretched at this time, and the folding of the folding parts and the stretching of the elastic connector are used for buffering, thereby improving the buffering performance of the anti-fall component, and the anti-fall component includes two folding parts, and flexible materials are not selected for a large area, which improves the impact resistance of the anti-fall component and further ensures the safety of the construction workers.

[0016] In any of the above technical solutions, the anti-fall assembly also includes: a hinge shaft connected between the two folding parts, and the two folding parts are connected through the hinge shaft.

[0017] In this technical solution, the anti-fall component also includes a hinge shaft rotatably connected to the two folding parts. The hinge shaft is connected between the two folding parts, and both of the two folding parts can rotate relative to the hinge shaft.

[0018] Specifically, when the anti-fall assembly is impacted, the two folding parts rotate relative to the hinge shaft, so that the folding angle between the two folding parts changes.

[0019] In the technical solution of the present application, a hinge shaft connected between the two folding parts is provided in the anti-fall assembly so that the two folding parts can be hinged together through the hinge shaft, thereby ensuring the stability of the mutual rotation and folding between the two folding parts.

[0020] In any of the above technical solutions, the embedded frame is provided with a limited position slideway;

[0021] The anti-falling component also includes: a limiting slider connected to the hinge shaft, and the limiting slider is slidably connected to the limiting slideway.

[0022] In this technical solution, a limit slideway is provided on the inner side wall of the embedded frame, a limit slider slides in the limit slideway, and the extension direction of the limit slideway is perpendicular to the plane where the anti-falling component is located. The limit slider is fixedly connected to the hinge shaft.

[0023] Specifically, when the anti-falling component is impacted, the two folding parts in the anti-falling component rotate through the hinge shaft, and the two folding parts are folded relative to each other, and the angle between the two folding parts becomes smaller. The hinge shaft slides downward in a direction perpendicular to the plane where the anti-falling component is located under the limit of the limit slider and the limit slideway.

[0024] It should be noted that by setting the stroke of the limit slider in the limit slide, the maximum folding angle between the two folding parts in the anti-fall assembly can be adjusted, wherein the stroke of the limit slider in the limit slide is positively correlated with the maximum folding angle between the two folding parts.

[0025] In the technical solution of the present application, a limit slide is provided on the embedded frame, and a corresponding limit slider is fixedly connected to the hinge shaft. The folding angle and moving direction of the anti-fall assembly are limited by the sliding of the limit slider in the limit slide. Compared with the anti-fall net made of fully flexible materials, it has better stability, avoids secondary injuries to falling persons or objects due to rollover, and improves the safety performance of the anti-fall device in construction.

[0026] In any of the above technical solutions, the number of the limiting slides is two, and the two limiting slides are respectively arranged on two opposite inner side walls of the embedded frame;

[0027] There are two limit sliders, which are respectively arranged at two ends of the hinge shaft.

[0028] In this technical solution, there are two limit slides and two limit sliders, and the limit slides are arranged one by one with the limit sliders. The two limit sliders are respectively fixedly connected to the two ends of the hinge shaft, and the two limit slides are respectively opened on the two inner side walls of the embedded frame, and the two inner side walls where the limit slides are opened are arranged opposite to each other.

[0029] It should be noted that there are four inner side walls in the embedded frame, two of which are provided with limit slideways, and the other two are connected to the two folding parts in the anti-fall assembly through elastic connectors. The inner side wall where the limit slideway is located and the inner side wall connected to the elastic connector are different inner side walls, which avoids the relative sliding of the limit slideway and the slider interfering with the stretching movement of the elastic connector.

[0030] In the technical solution of the present application, by providing two limit sliders and two limit sliders, the stability of the movement of the anti-fall component relative to the embedded frame can be further improved.

[0031] In any of the above technical solutions, the folding portion includes: a net frame; and an anti-falling net fixedly connected to the inner side wall of the net frame.

[0032] In the technical solution of the present application, the folding part includes a net frame and an anti-falling net, the two net frames of the two folding parts are hinged to each other, and the anti-falling net is installed on the inner side walls of the two net frames. The net frame is a rigid structure to improve the stability of the anti-falling assembly including the two folding parts, and the anti-falling net is a grid-like structure that can allow falling objects such as gravel and liquid to pass through the anti-falling net to avoid accumulation on the anti-falling assembly.

[0033] In any of the above technical solutions, the anti-fall net includes a flexible anti-fall net, wherein the mesh area of ​​the flexible anti-fall net ranges from 5 cm to 20 cm.

[0034] In this technical solution, the anti-fall net is set as a flexible anti-fall net, which can further cushion the person or object falling on the anti-fall component, so that the falling person or falling object can have soft contact with the anti-fall component to avoid damage to them.

[0035] In this technical solution, the mesh area of ​​the flexible anti-fall net is set to between 5cm and 20cm, which can ensure that some smaller falling objects and liquids can fall through the flexible anti-fall net and avoid accumulation on the anti-fall component. It can also effectively prevent larger falling objects and falling people from passing through the anti-fall component and contacting the ground.

[0036] In the technical solution of the present application, by selecting a flexible anti-fall net in the anti-fall component and limiting the mesh area of ​​the flexible anti-fall net, the buffering performance of the anti-fall component can be improved. At the same time, it can also ensure that some smaller falling objects and liquids can fall through the flexible anti-fall net, thereby preventing larger falling objects and falling people from passing through the anti-fall component, thereby improving the anti-fall performance.

[0037] In any of the above technical solutions, the elastic connector includes:

[0038] A first fixing member is fixedly connected to the inner wall of the embedded frame;

[0039] An elastic member, one end of which is detachably connected to the first fixing member;

[0040] The second fixing member is fixedly connected to the folding portion, and the second fixing member is detachably connected to the other end of the elastic member.

[0041] In this technical solution, the elastic connecting member includes a first fixing member fixedly connected to the inner wall of the embedded frame, and a second fixing member fixedly connected to the folding part, and an elastic member is connected between the first fixing member and the second fixing member, which can effectively provide a buffering effect for the anti-fall assembly.

[0042] In this technical solution, the first fixing member is detachably connected to the elastic member, and the second fixing member is detachably connected to the elastic member. When installing the anti-fall device for construction, the embedded frame can be installed first, and after the embedded frame is installed, the anti-fall assembly is installed on the embedded frame by connecting the first fixing member, the elastic member and the second fixing member, which simplifies the installation convenience of the anti-fall device for construction.

[0043] It should be noted that the first fixing member and the elastic member can rotate relative to each other, and the second fixing member and the elastic member can rotate relative to each other, thereby improving the flexibility of the elastic connecting member to deform when subjected to force.

[0044] In the technical solution of the present application, the elastic connecting member includes a first fixing member, an elastic member and a second fixing member which are detachably connected to each other. The embedded frame and the anti-falling assembly in the anti-falling device for construction can be installed separately through the elastic connecting member, thereby improving the flexibility and convenience of installing the anti-falling device for construction.

[0045] In any of the above technical solutions, the elastic member is a tension spring.

[0046] In the technical solution of the present application, by selecting the elastic member as a tension spring, when the anti-fall component is impacted, the tension spring is in a tensioned state, thereby improving the buffering performance of the anti-fall component.

[0047] According to the second aspect of the utility model, a horizontal well is proposed, comprising: a well wall and a construction anti-falling device in any of the above-mentioned technical solutions, and thus has all the beneficial technical effects of the construction anti-falling device in any of the above-mentioned technical solutions, which will not be repeated here.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0061] Refer to the following Figures 1 to 5 A construction anti-falling device 100 and a horizontal well 200 according to some embodiments of the present invention are described.

[0062] Figure 1 One of the structural schematic diagrams of the construction anti-falling device provided in some embodiments of the present application is shown, Figure 2 The second structural schematic diagram of the construction anti-falling device provided in some embodiments of the present application is shown. Figure 3 The third structural schematic diagram of the construction anti-falling device provided in some embodiments of the present application is shown as follows: Figure 1 , Figure 2 and Figure 3As shown, the first embodiment of the utility model provides a construction anti-falling device 100, comprising: an anti-falling assembly 110, an embedded frame 120 and at least two elastic connectors 130. The anti-falling assembly 110 comprises two folding parts 112, and the two folding parts 112 are hinged to each other; the embedded frame 120 encloses a folding net frame 1122, and the embedded frame 120 is used to be fixedly connected to the wall of the horizontal hole; one end of the at least two elastic connectors 130 is respectively connected to the two folding parts 112, and the other end of the at least two elastic connectors 130 is respectively connected to the embedded frame 120.

[0063] In this embodiment, the anti-fall assembly 110 includes two folding parts 112 hinged to each other. The two folding parts 112 can rotate with each other to be folded, that is, the two folding parts 112 can be hinged to each other to change the angle between the two folding parts 112.

[0064] like Figure 2 As shown, specifically, when the anti-fall component 110 is not subjected to a falling impact, the two folding portions 112 of the anti-fall component 110 are horizontal, that is, when the anti-fall component 110 is not subjected to an impact, the angle θ1 between the two folding portions 112 ranges from 170° to 190°.

[0065] like Figure 3 As shown, when a construction worker or an object accidentally falls onto the anti-falling assembly 110, the upper surface of the anti-falling assembly 110 is impacted by the fall, and the angle between the two folding portions 112 becomes smaller, that is, the two folding portions 112 are folded to cushion the construction worker or object. When the anti-falling assembly 110 is impacted, the angle θ2 between the two folding portions 112 is in the range of 150° to 120°.

[0066] In this embodiment, the embedded frame 120 can be embedded in the wall of the horizontal hole, so as to fix the construction anti-fall device 100 on the horizontal hole. The embedded frame 120 is enclosed on the outside of the anti-fall component 110, that is, the enclosed area of ​​the embedded frame 120 is larger than the area of ​​the two folding parts 112 of the anti-fall component 110. When the embedded frame 120 is enclosed on the outside of the anti-fall component 110, there is a large gap between the embedded frame 120 and the anti-fall component 110, ensuring that the anti-fall component 110 will not contact and interfere with the embedded frame 120, so that the two folding parts 112 in the anti-fall component 110 can be freely folded when impacted to buffer the falling objects.

[0067] Exemplarily, the embedded frame 120 is provided with fixing holes, and the embedded frame 120 is fixed to the wall of the horizontal well by tightening bolts.

[0068] In this embodiment, the elastic connector 130 is used to connect the anti-falling component 110 and the embedded frame 120. The number of the elastic connectors 130 is at least two. Each of the two folding portions 112 in the anti-falling component 110 is connected to one end of at least one elastic connector 130, and the other end of the elastic connector 130 is connected to the inner wall of the embedded frame 120. The elastic connector 130 is a tensile elastic structure. When the anti-falling component 110 is impacted and folded, the elastic connector 130 is in a stretched state.

[0069] Specifically, the number of the elastic connectors 130 is 2N, wherein N elastic connectors 130 are connected between one of the two folding portions 112 and the embedded frame 120 , and the other N elastic connectors 130 are connected between the other folding portion 112 and the embedded frame 120 .

[0070] Exemplarily, the number of the elastic connectors 130 is six, of which three elastic connectors 130 are connected between one of the two folding portions 112 and the embedded frame 120 , and the other three elastic connectors 130 are connected between the other folding portion 112 and the embedded frame 120 .

[0071] It should be noted that the anti-falling device 100 for construction in the present application is an anti-falling component 110 for anti-falling buffering, and the anti-falling component 110 is buffered by folding two mutually hinged folding parts 112 and the stretching elastic force of the elastic connector 130, without the need to set a large amount of flexible materials. When construction workers fall, it can not only provide a better buffering effect, but also prevent the finer fibers of the flexible material from cutting the construction workers, and improve the impact resistance and durability of the anti-falling component 110.

[0072] In the embodiment of the present application, the anti-falling device 100 for construction includes an embedded frame 120 fixed on the wall of the horizontal hole, and an anti-falling assembly 110 enclosed by the embedded frame 120, the anti-falling assembly 110 and the embedded frame 120 are connected by an elastic connector 130, and the anti-falling assembly 110 includes two mutually hinged folding parts 112. When a construction worker or an object falls on the anti-falling assembly 110, the two folding parts 112 in the anti-falling assembly 110 are folded, and the elastic connector 130 connected to the two folding parts 112 is stretched at this time, and the folding of the folding parts 112 and the stretching of the elastic connector 130 are used for buffering, thereby improving the buffering performance of the anti-falling assembly 110, and the anti-falling assembly 110 includes two folding parts 112, and flexible materials are not selected for a large area, thereby improving the impact resistance of the anti-falling assembly 110, and further ensuring the safety of the construction workers.

[0073] Figure 4Schematic diagram of the structure of the anti-falling assembly 110 in some embodiments of the present application is shown, such as Figure 2 , Figure 3 and Figure 4 As shown, in any of the above embodiments, the anti-fall assembly 110 further includes: a hinge shaft 114 connected between the two folding parts 112 , and the two folding parts 112 are connected through the hinge shaft 114 .

[0074] In this embodiment, the anti-falling assembly 110 further includes a hinge shaft 114 rotatably connected to the two folding parts 112 . The hinge shaft 114 is connected between the two folding parts 112 , and both of the two folding parts 112 can rotate relative to the hinge shaft 114 .

[0075] Specifically, when the anti-falling assembly 110 is impacted, the two folding portions 112 rotate relative to the hinge shaft 114 , so that the folding angle between the two folding portions 112 changes.

[0076] Exemplarily, the hinge shaft 114 includes a shaft body and a bearing. The bearing is sleeved on the shaft body and can rotate relative to the shaft body. The bearing is fixedly connected to the two folding parts 112 so that the two folding parts 112 can rotate smoothly relative to the hinge shaft 114.

[0077] In the embodiment of the present application, a hinge shaft 114 connected between the two folding parts 112 is provided in the anti-fall component 110, so that the two folding parts 112 can be hinged together through the hinge shaft 114, thereby ensuring the stability of the mutual rotation and folding between the two folding parts 112.

[0078] like Figure 1 , Figure 2 and Figure 3 As shown, in any of the above embodiments, the embedded frame 120 is provided with a limited position slideway 140;

[0079] The anti-falling assembly 110 further includes: a limiting slider 116 connected to the hinge shaft 114 , and the limiting slider 116 is slidably connected to the limiting slideway 140 .

[0080] In this embodiment, the inner wall of the embedded frame 120 is provided with a limit slide 140, in which a limit slider 116 slides, and the extension direction of the limit slide 140 is perpendicular to the plane where the anti-falling component 110 is located. The limit slider 116 is fixedly connected to the hinge shaft 114.

[0081] Specifically, when the anti-falling assembly 110 is impacted, the two folding parts 112 in the anti-falling assembly 110 rotate through the hinge shaft 114, and the two folding parts 112 are relatively folded, and the angle between the two folding parts 112 becomes smaller. The hinge shaft 114 slides downward in a direction perpendicular to the plane where the anti-falling assembly 110 is located under the limitation of the limiting slider 116 and the limiting slideway 140.

[0082] Exemplarily, a hydraulic component is further provided in the limiting slide 140 , and the hydraulic component is in contact with the limiting slider 116 . When the limiting slider 116 slides downward, the hydraulic component has a buffering effect on the two folding parts 112 .

[0083] It should be noted that by setting the stroke of the limit slider 116 in the limit slide 140, the maximum folding angle between the two folding parts 112 in the anti-fall assembly 110 can be adjusted, wherein the stroke of the limit slider 116 in the limit slide 140 is positively correlated with the maximum folding angle between the two folding parts 112.

[0084] In the embodiment of the present application, a limiting slide 140 is provided on the embedded frame 120, and a corresponding limiting slider 116 is fixedly connected to the hinge shaft 114. The folding angle and moving direction of the anti-fall assembly 110 are limited by the sliding of the limiting slider 116 in the limiting slide 140. Compared with the anti-fall net 1124 made of fully flexible materials, it has better stability, avoids secondary injuries to falling personnel or objects due to rollover, and improves the safety performance of the construction anti-fall device 100.

[0085] In any of the above embodiments, the number of the limiting slideways 140 is two, and the two limiting slideways 140 are respectively arranged on two opposite inner side walls of the embedded frame 120;

[0086] There are two limit sliders 116 , and the two limit sliders 116 are respectively disposed at two ends of the hinge shaft 114 .

[0087] In this embodiment, there are two limit slides 140 and two limit sliders 116, and the limit slides 140 are arranged one by one with the limit sliders 116. The two limit sliders 116 are respectively fixedly connected to the two ends of the hinge shaft 114, and the two limit slides 140 are respectively opened on the two inner side walls of the embedded frame 120, and the two inner side walls where the limit slides 140 are opened are arranged opposite to each other.

[0088] It should be noted that the embedded frame 120 has four inner side walls, two of which are provided with limited slideways 140, and the other two are connected to the two folding parts 112 in the anti-falling assembly 110 through the elastic connector 130. The inner side wall where the limited slideway 140 is located and the inner side wall connected to the elastic connector 130 are different inner side walls, which prevents the relative sliding of the limited slideway 140 and the slider from interfering with the stretching movement of the elastic connector 130.

[0089] In the embodiment of the present application, by providing two limit sliders 116 and two limit sliders 116 , the stability of the movement of the anti-falling component 110 relative to the embedded frame 120 can be further improved.

[0090] In any of the above embodiments, the folding portion 112 includes: a net frame 1122 ; and an anti-fall net 1124 fixedly connected to the inner wall of the net frame 1122 .

[0091] In the embodiment of the present application, the folding portion 112 includes a mesh frame 1122 and an anti-falling net 1124. The two mesh frames 1122 of the two folding portions 112 are hinged to each other, and the anti-falling net 1124 is installed on the inner side walls of the two mesh frames 1122. The mesh frame 1122 is a rigid structure, which improves the stability of the anti-falling assembly 110 including the two folding portions 112. The anti-falling net 1124 is a grid-like structure, which can allow falling objects such as gravel and liquid to pass through the anti-falling net 1124 to avoid accumulation on the anti-falling assembly 110.

[0092] In any of the above embodiments, the anti-falling net 1124 includes a flexible anti-falling net 1124, wherein the mesh area of ​​the flexible anti-falling net 1124 ranges from 5 cm to 20 cm.

[0093] In this embodiment, the anti-fall net 1124 is set as a flexible anti-fall net 1124, which can further cushion the person or object falling on the anti-fall component 110, so that the falling person or falling object can have soft contact with the anti-fall component 110 to avoid damage caused by the anti-fall component 110.

[0094] In this embodiment, the mesh area of ​​the flexible anti-fall net 1124 is set to between 5 cm and 20 cm, which can ensure that some smaller falling objects and liquids can fall through the flexible anti-fall net 1124 and avoid accumulation on the anti-fall component 110. It can also effectively prevent larger falling objects and falling people from passing through the anti-fall component 110 and contacting the ground.

[0095] In the embodiment of the present application, by selecting a flexible anti-fall net 1124 in the anti-fall component 110 and limiting the mesh area of ​​the flexible anti-fall net 1124, the buffering performance of the anti-fall component 110 can be improved. At the same time, it can also ensure that some smaller falling objects and liquids can fall through the flexible anti-fall net 1124, thereby preventing larger falling objects and falling people from passing through the anti-fall component 110, thereby improving the anti-fall performance.

[0096] In any of the above embodiments, the elastic connecting member 130 includes:
