Description

Technical Field

[0001] The invention relates to the technical field of building safe construction passages, and in particular to a building safe construction passage structure capable of reducing the risk of injuries caused by falling objects. Background Art

[0002] Construction safety passages refer to passages demarcated in construction sites, engineering sites and other construction sites to ensure the safety of construction personnel and equipment. The purpose of setting up construction safety passages is to achieve the following functions:

[0003] 1. Divert the flow of people: There are usually many people on the construction site. In order to prevent people from crossing, the passage can guide the flow of people in the right direction to avoid congestion and traffic chaos.

[0004] 2. Prevent collisions: There are often large-scale machinery and transport vehicles coming and going at the construction site. By setting up safe passages, it can be ensured that there is a sufficient safe distance between construction workers and machinery and vehicles to avoid accidental collisions.

[0005] 3. Prevent falling: During high-altitude construction or cantilever operations, protective railings, safety nets, etc. can be set up in the construction safety passage to prevent people or objects from falling from heights and ensure the safety of construction workers.

[0006] 4. Management facilities: By setting up construction safety passages, the construction site can be managed, which facilitates the supervision of the work of construction personnel and ensures that the work is carried out in accordance with the specifications.

[0007] In terms of preventing falls, most of the time, guardrails are used to support and protect the sides, and safety nets are set up above to block falling objects. The materials generally used for the protective nets of building safety construction passages include polyethylene, polypropylene filaments, polypropylene, nylon, etc. These materials have the characteristics of high tensile strength and excellent elasticity, which can ensure the safety of falling objects under normal circumstances. However, this type of protective net also has the defect of insufficient bearing capacity. If a serious collapse problem occurs at the construction site and a large number of falling objects continue to fall, the general protective net will be directly smashed through, and the entire protective structure will be destroyed, resulting in failure to provide effective protection for workers. Summary of the invention

[0008] The invention discloses a safe construction passage structure for buildings that can reduce the risk of injuries caused by falling objects. The invention aims to solve the technical problem that if a serious collapse problem occurs at a construction site and a large amount of falling objects continue to fall, a general protective net will be directly smashed through, and the entire protective structure will be damaged, resulting in failure to provide effective protection for workers.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A safe construction passage structure for reducing the risk of injury from falling objects, comprising: a falling object resisting mechanism, a side guiding mechanism arranged on the falling object resisting mechanism, a plurality of columns arranged at the bottom of the falling object resisting mechanism, and a side protection mechanism arranged on the columns;

[0011] The falling object blocking mechanism includes two side support shells, a side support frame connected between the two side support shells, a winding shaft arranged in the side support shells, a wire rope net wound around the winding shaft, and elastic nets arranged on both sides of the wire rope net;

[0012] The two ends of the winding shaft are respectively fixedly connected with a first gear, and each first gear is respectively meshed with a second gear, a first support shaft is simultaneously connected between the two second gears, and a central support is movably connected to the middle section of the first support shaft, a first torsion spring is simultaneously connected between the central support and the first support shaft, a side sleeve is arranged on the outside of the elastic net, and the outer walls of the opposite sides of the two side support frames are respectively connected with an inner support rod through a fixed frame, and the side sleeve is movably sleeved on the outside of the inner support rod;

[0013] The outer walls of the two side support shells on the opposite side are respectively fixedly connected with an upper guide plate and a lower guide plate from top to bottom, and the lower guide plate is wider than the upper guide plate, the outer walls on the two sides facing each other of the upper guide plate are respectively fixedly connected with an upper folding plate and a central folding plate from top to bottom, and one side of the upper folding plate and the central folding plate are simultaneously connected with a side baffle plate, and the inner walls of the two side support shells on the opposite side are respectively penetrated with a through groove, and the through groove is located between the upper guide plate and the lower guide plate;

[0014] The two ends of the wire rope net are respectively attached to the winding shafts on both sides, and a clamping frame is connected to the outer wall of one side of the winding shaft by bolts, and the clamping frame is used to fix the wire rope net;

[0015] A groove is arranged at the center of the elastic net, and the fixing frame is connected to the groove.

[0016] By providing a falling object resistance mechanism, if the falling object is heavy, after the falling object falls onto the wire rope net, the impact force of its fall can drive the wire rope net with poor elasticity to fall, and during the falling process, the first torsion spring is stretched to extend the wire rope net on the shaft, thereby providing a buffering force for heavy objects to the wire rope net synchronously with the first torsion spring. Compared with directly using an elastic net, under this structure, under the dual effects of ensuring firmness and providing buffering force, the load-bearing capacity of the protective structure can be optimized to the greatest extent, thereby reducing the risk of falling object injuries. At the same time, under the action of the folding structure composed of the upper folding plate, the center folding plate, the upper guide plate and the lower guide plate, the elastic net can be guided to be unfolded or recovered during the loosening or rewinding of the wire rope net. With the setting of the inner support rod, the elastic nets on both sides of the wire rope net in the falling resistance area can be kept unfolded, thereby expanding the falling object storage capacity of the wire rope net, and effectively blocking falling object fragments, thereby optimizing the protection effect.

[0017] In a preferred solution, the side guide mechanism includes a plurality of L-shaped guide frames, and the bottom end of each L-shaped guide frame is respectively connected to a presser foot, and the two sides of the plurality of L-shaped guide frames located on both sides are connected to the outer wall of the side support frame through a hinge seat;

[0018] The outer walls of the two L-shaped guide frames located in the middle are respectively connected to the second support shaft, and the outer cover of the second support shaft is connected to the support cover, which is fixed to the outer wall of the side support frame and connected to one side of the adjacent L-shaped guide frames;

[0019] A second torsion spring is connected between the second support shaft and the inner wall of the support cover, one end of the second support shaft passes through the support cover and is connected to a paddle, and a support frame is fixedly connected to an outer wall of one side of the second support shaft;

[0020] A plurality of thorn needles are equidistantly arranged at one end of the support frame, a slot is penetrated through the top of the support cover, and a fixing plate is fixedly connected to the slot by bolts, and a tempered glass bracket is fixedly connected to the bottom end of the fixing plate;

[0021] The tempered glass support comprises a folded corner, and a plurality of needles are fitted corresponding to the folded corner, and the top outer wall of each side support frame is respectively fixedly connected to the limited position support frame.

[0022] By providing a side guiding mechanism, if the construction site is abnormal and there is a large amount of falling objects falling continuously, the safe construction passage needs to be used as an evacuation passage. If a large amount of falling objects repeatedly impact the top of the obliquely arranged L-shaped guide frame, or repeatedly impact the wire rope net and drive it to fall, the multiple impacts on the pressure foot can drive multiple needles to repeatedly impact the corners of the tempered glass bracket, which can break the tempered glass bracket and eliminate the limiting effect on the support frame, so that the top ends of the L-shaped guide frames on both sides are against each other, and the resistance to falling objects is strengthened by forming a triangular bracket, and the falling objects are guided by the inclined surface to fall from both sides, thereby avoiding excessive weight on the top and causing the channel to collapse, thereby ensuring the stability of the channel during the evacuation process.

[0023] In a preferred solution, the side protection mechanism includes a first connecting rod, a third connecting rod and a fourth connecting rod, and the first connecting rod, the third connecting rod and the fourth connecting rod are hinged to each other from top to bottom, the first connecting rod is hinged to the tail end of each presser foot, and the bottom end of the fourth connecting rod is connected to the bottom plate through a hinge;

[0024] The outer wall of one side of the column at both ends is fixedly connected with a side support, and the bottom plate is fixedly connected between adjacent side supports, columns and between two adjacent columns, and the inner walls of the side supports and columns are respectively provided with sliding grooves;

[0025] The hinges of the first and third links are hinged with a second link at the same time, and one end of the second link is connected to a slider, which is movably connected in the slide slot, and the outer walls on the same side of multiple third and fourth links are simultaneously connected to a protective net.

[0026] A side protection mechanism is provided between multiple columns, which is mainly used to prevent workers from walking between the columns on a daily basis. When the multiple L-shaped guide frames in the side guide mechanism pop up, the third connecting rod and the fourth connecting rod can drive the protection net to bend inward, so that the third connecting rod and the fourth connecting rod can push inward in the multiple columns. While the protection net is used as a protection against debris, it can also serve as a reminder of the narrowing of the channel, ensuring that people can pass quickly from the center of the channel, avoiding excessive contact with the edge and contact with falling objects guided to both sides by the side guide mechanism, thereby further ensuring safety during the evacuation process.

[0027] From the above, it can be seen that a safe construction passage structure for reducing the risk of injuries caused by falling objects comprises: a falling object resistance mechanism, a side guiding mechanism arranged on the falling object resistance mechanism, a plurality of columns arranged at the bottom of the falling object resistance mechanism and a side protection mechanism arranged on the columns; the falling object resistance mechanism comprises two side support shells, a side support frame connected between the two side support shells, a winding shaft arranged in the side support shells, a wire rope net wound around the winding shaft and an elastic net arranged on both sides of the wire rope net; the two ends of the winding shaft are respectively fixedly connected to a first gear, and each first gear is respectively meshed with a second gear, a first support shaft is simultaneously connected between the two second gears, and the middle section of the first support shaft is movable The outer wall of the two side support shells is connected to the inner support rod through a fixed frame, and the side sleeve is movably connected to the outer wall of the inner support rod; the outer wall of the two side support shells is fixedly connected to the upper guide plate and the lower guide plate from top to bottom, and the lower guide plate is wider than the upper guide plate; the outer walls of the two opposite sides of the upper guide plate are fixedly connected to the upper folding plate and the center folding plate from top to bottom, and the upper folding plate and the center folding plate are connected to the side baffle at the same time; the inner wall of the two side support shells is penetrated by a through groove, and the through groove is located between the upper guide plate and the lower guide plate. The construction safety construction channel structure that can reduce the risk of falling objects has the technical effect of optimizing the load-bearing capacity of the protective structure to a large extent under the dual effects of ensuring firmness and providing buffering force, thereby reducing the risk of falling objects.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The invention discloses a building safety construction passage structure capable of reducing the risk of injury from falling objects, which is mainly used in the scene of building a safety construction passage.

[0040] Reference Figure 1-Figure 4 , a building safety construction passage structure capable of reducing the risk of injury from falling objects, comprising: a falling object resisting mechanism 2, a side guiding mechanism 3 arranged on the falling object resisting mechanism 2, a plurality of columns 1 arranged at the bottom of the falling object resisting mechanism 2, and a side protection mechanism 4 arranged on the columns 1;

[0041] The falling object blocking mechanism 2 includes two side support shells 201, a side support frame 202 connected between the two side support shells 201, a winding shaft 209 arranged in the side support shell 201, a wire rope net 212 wound around the winding shaft 209, and an elastic net 210 arranged on both sides of the wire rope net 212;

[0042] The two ends of the shaft 209 are respectively fixedly connected with the first gear 204, and each first gear 204 is respectively meshed with the second gear 205, and the first support shaft 207 is simultaneously connected between the two second gears 205, and the middle section of the first support shaft 207 is movably connected with the central support 208, and the first torsion spring 206 is simultaneously connected between the central support 208 and the first support shaft 207, and the outer side of the elastic net 210 is provided with a side sleeve 213, and the outer walls of the opposite sides of the two side support frames 202 are respectively connected with the inner support rod 214 through the fixing frame 211, and the side sleeve 213 is movably sleeved outside the inner support rod 214;

[0043] The outer walls of the two side support shells 201 on the opposite side are respectively fixedly connected with an upper guide plate 203 and a lower guide plate 219 from top to bottom, and the lower guide plate 219 is wider than the upper guide plate 203. The outer walls of the upper guide plate 203 on the opposite sides are respectively fixedly connected with an upper folding plate 216 and a central folding plate 217 from top to bottom, and one side of the upper folding plate 216 and the central folding plate 217 is simultaneously connected with a side baffle 218. The inner walls of the two side support shells 201 on the opposite side are respectively penetrated with a through groove 220, and the through groove 220 is located on the upper guide plate 203. The structure mainly realizes safety protection by catching the falling objects through the steel wire rope net 212, wherein the elastic force of the first torsion spring 206 and the meshing resistance between the first gear 204 and the second gear 205 can ensure the stable support of both ends of the steel wire rope net 212. If the falling object is heavy, after the falling object falls onto the steel wire rope net 212, the impact force of its fall can drive the steel wire rope net 212 with poor elasticity to fall, and during the falling process, the first torsion spring 206 stretches to extend the steel wire rope net 212 on the winding shaft 209, thereby being able to engage with the first torsion spring 206 to prevent the steel wire rope net 212 from falling. A torsion spring 206 synchronously provides a buffer force for heavy objects to the wire rope net 212. Compared with directly using an elastic net, under this structure, under the dual effects of ensuring firmness and providing buffer force, the load-bearing capacity of the protective structure can be optimized to a large extent, thereby reducing the risk of falling objects causing injuries. At the same time, under the action of the folding structure composed of the upper folding plate 216, the center folding plate 217, the upper guide plate 203 and the lower guide plate 219, the wire rope net 212 is passed through the upper guide plate 203 and the lower guide plate 219, and the elastic net 210 is formed by the upper folding plate 216 and the lower guide plate 219. The central folding plate 217 passes through the plates 203, and is located between the elastic net 210 and the wire rope net 212 at the edge of the fold. Based on the settings of the side sleeves 213 and the inner support rods 214, the elastic net 210 can be guided to be unfolded or recovered during the loosening or rewinding of the wire rope net 212. With the setting of the inner support rods 214, the elastic nets 210 on both sides of the wire rope net 212 in the falling resistance area can be kept unfolded, thereby expanding the amount of falling objects that can be stored in the wire rope net 212, and effectively blocking falling object fragments, thereby optimizing the protection effect.

The top outer wall of each side bracket 202 is fixedly connected to the limited position bracket 301 respectively.

If a large amount of falling objects repeatedly impact the top of the obliquely arranged L-shaped guide frame 302, or repeatedly impact the wire rope net 212 and drive it to fall, multiple impacts on the presser foot 305 can drive multiple needles 307 to repeatedly impact the folded corner of the tempered glass bracket 311. Based on the material of the tempered glass bracket 311, the limiting effect of the support frame 308 can be guaranteed under normal conditions to ensure that multiple L-shaped guide frames 302 are located on the side and will not cause excessive More shielding, and when the thorn needle 307 repeatedly impacts the most vulnerable position of the corner, the tempered glass bracket 311 can be broken, eliminating the limiting effect on the support frame 308, and under the action of the second torsion spring 306, the L-shaped guide frames 302 on both sides can be rotated inward, and under the action of the limiting support frame 301, the top ends of the L-shaped guide frames 302 are abutted against each other, and the resistance to falling objects is strengthened by forming a triangular bracket, and the falling objects are guided by the inclined surface to fall from both sides, thereby avoiding the collapse of the channel caused by excessive weight on the top, thereby ensuring the stability of the channel during the evacuation process. At the same time, based on the fact that the tempered glass bracket 311 is fixed by bolts with the fixing plate 310, when the L-shaped guide frame 302 is not damaged, the tempered glass bracket 311 can be replaced separately and fixed with bolts to achieve the reuse of the construction channel.

While using the protective net 409 as a debris protection, it can also serve as a reminder of the narrowing of the channel, ensuring that people can pass quickly from the center of the channel, avoiding excessive contact with the edge position and contact with falling objects guided to both sides by the side guide mechanism 3, thereby further ensuring safety during the evacuation process.

[0054] Working principle: This structure mainly realizes safety protection by catching falling objects through the set steel wire rope net 212, wherein the elastic force of the first torsion spring 206 and the meshing resistance between the first gear 204 and the second gear 205 can ensure the stable support of both ends of the steel wire rope net 212. If the falling object is heavy, after the falling object falls onto the steel wire rope net 212, the impact force based on its fall can drive the steel wire rope net 212 with poor elasticity to fall, and during the falling process, the first torsion spring 206 stretches to extend the steel wire rope net 212 on the shaft 209, thereby providing a buffering force for heavy objects to the steel wire rope net 212 synchronously with the first torsion spring 206.

With the setting of the inner support rod 214, the elastic nets 210 on both sides of the wire rope net 212 in the falling resistance area can be kept in the deployed state, thereby expanding the falling object storage capacity of the wire rope net 212, and effectively blocking the falling object fragments, thereby optimizing the protection effect.
