Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering construction, and in particular to a safety shoe cover for building engineering steel bar panel acceptance. BACKGROUND

[0002] In the process of building construction and acceptance, the steel bar joint, bending and size quantity on the steel bar panel need to be checked and accepted by the construction personnel. The construction personnel need to walk on the steel bar panel during the acceptance process. Since the new employees just enter the front-line engineering work, they lack the work experience of walking on the steel bar panel, and are prone to slipping, falling and other safety accidents, which brings inconvenience to the construction acceptance work. Therefore, it is necessary to provide a safety shoe cover for building engineering steel bar panel acceptance. SUMMARY

[0003] The technical problem to be solved by the present application is that the detection personnel walk on the steel bar panel in the steel bar engineering acceptance, and are prone to slipping, falling and other safety accidents due to unstable foot stepping. A safety shoe cover for building engineering steel bar panel acceptance is disclosed. Four sliding blocks moving up and down are installed at four ports of a cross-shaped installation groove in the bottom surface of the shoe, and the lapped steel bars are clamped in the installation groove under the action of the spring elastic force, effectively increasing the contact area of the shoe sole and the lapped steel bars, and avoiding the occurrence of personal safety accidents.

[0004] The technical solution adopted by the present application to solve the technical problem is: a safety shoe cover for building engineering steel bar panel acceptance, comprising a shoe sole and a strap arranged above the shoe sole. A cross-shaped installation groove is arranged in the middle of the bottom surface of the shoe sole along the front and rear ends and the left and right ends. Four sliding blocks are respectively arranged at the four ports of the installation groove and are in sliding connection with the inner side of the installation groove. Two symmetrically arranged installation holes are longitudinally arranged in the interior of each sliding block. A spring is arranged in each installation hole and is connected with the inner top surface of the installation groove. The sliding blocks are movably arranged in the installation groove through the spring.

[0005] A first connecting rod is connected between the two sliding blocks at the left and right ends in the installation groove. A second connecting rod and a third connecting rod are respectively arranged on the opposite surfaces of the two sliding blocks at the front and rear ends in the installation groove and are connected with the first connecting rod. A first hanging ring and a second hanging ring in one piece are respectively arranged below the second connecting rod and the third connecting rod.

[0006] Inside the sole, two parallel support rods, matching the first and second hanging rings, are arranged on both sides of the first connecting rod. The second and third connecting rods are respectively fitted onto the first and second support rods via the first and second hanging rings below, and the second connecting rod and the first support rod, and the third connecting rod and the second support rod respectively form a lever structure.

[0007] Furthermore, a sliding groove matching the slider is provided on the inner side of the mounting groove corresponding to the position of the slider, and the slider moves up and down inside the mounting groove along the sliding groove.

[0008] Furthermore, the top surface of the slider has a through hole corresponding to the spring position, one end of the spring extends through the through hole to the outside of the slider and connects to the top surface inside the mounting groove, and the other end of the spring is fixed to the bottom surface inside the mounting hole.

[0009] Furthermore, the second connecting rod is provided with a first arc-shaped hook with a groove in the middle at one end near the first connecting rod, and the second connecting rod is engaged with the outer periphery of the first connecting rod through the first arc-shaped hook at the end;

[0010] The diameter of the third connecting rod is the same as the width of the groove at one end of the second connecting rod. The third connecting rod is provided with a second arc-shaped hook at one end near the first connecting rod. The third connecting rod is located at one end of the second arc-shaped hook, which extends into the groove at the middle of the first arc-shaped hook on the second connecting rod and is engaged with the outer periphery of the first connecting rod.

[0011] Furthermore, the side of the sole is provided with a first perforation and a second perforation that match the outer diameter of the first support rod and the second support rod, respectively, and both the first perforation and the second perforation extend into the interior of the sole.

[0012] The first support rod and the second support rod extend through the first and second perforations, respectively, through the first and second hanging rings, into the interior of the shoe sole, and are movably connected to the first and second hanging rings.

[0013] Furthermore, the inner part of the sole located outside the mounting groove has a grid-like hollow structure, and an insole is provided on the top surface of the sole above the grid-like hollow structure. The insole is fixed to the sole surface by adhesive.

[0014] Furthermore, a rubber buffer pad is provided on the bottom surface of the slider, and the buffer pad is fixed to the bottom surface of the slider by adhesive.

[0015] Furthermore, the outer surface of the slider has a square structure or an arc-shaped surface structure.

[0016] Furthermore, the first connecting rod, the second connecting rod, the third connecting rod, the first support rod, the second support rod, and the four sliders are all made of stainless steel.

[0017] The first connecting rod, the second connecting rod, the third connecting rod, and the corresponding slider are all fixedly connected by welding.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: a safety shoe cover for the acceptance of steel reinforcement panels in building engineering, by opening a cross-shaped installation groove on the bottom surface of the shoe sole, installing four sliders at the four ends of the installation groove and slidingly connecting them to the inner side of the installation groove, and by opening a set of symmetrically distributed installation holes on the sliders, with springs installed inside the installation holes and connected to the top surface of the installation groove on the bottom surface of the shoe sole, when the slider in the installation groove on the bottom surface of the shoe sole contacts the surface of the overlapping steel reinforcement on the steel reinforcement panel, the slider moves upward along the groove under the action of the center of gravity pressure, the spring contracts, and under the action of the spring force, not only is the overlapping steel reinforcement clamped in the installation groove, but the contact area between the shoe sole and the overlapping steel reinforcement is also increased;

[0019] By setting a first connecting rod between two sliders at the left and right ends of the sole, and setting a second connecting rod and a third connecting rod between two sliders at the front and rear ends of the sole respectively, which are connected to the first connecting rod, the second connecting rod and the third connecting rod form a lever structure with the first support rod and the second support rod connected to the inside of the sole. Since the two overlapping steel bars are not on the same plane, by using the lever principle, when the sliders at the front and rear ends of the sole are locked with the top overlapping steel bar, the sliders move upward, causing the other ends of the second and third connecting rods to press down on the first connecting rod, thereby locking the sliders at the left and right ends of the sole onto the bottom overlapping steel bar surface. When the inspector walks on the steel bar panel, he only needs to place the cross-shaped mounting groove on the bottom of the sole at the intersection of the overlapping steel bar panel, which can effectively increase the contact area between the user's foot and the steel bar surface and protect the user's personal safety.

[0020] By designing the other ends of the second and third connecting rods as arc-shaped hook structures, and by opening a groove on the first arc-shaped hook at one end of the second connecting rod that matches the second arc-shaped hook at one end of the third connecting rod, it is easy to install the second and third connecting rods on the first connecting rod.

[0021] By setting cushioning pads on the bottom of the four sliders on the sole, the friction between the sliders and the steel reinforcement is increased, further enhancing the anti-slip effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9This invention provides a technical solution: a safety shoe cover for the acceptance of steel reinforcement panels in building engineering, including a shoe sole 1 and a strap 2 disposed above the shoe sole 1. The bottom surface of the shoe sole has a cross-shaped mounting groove 11 along the front and rear ends and the left and right ends. At the four ends of the mounting groove 11, a slider 3 is installed and slidably connected to the inner side of the mounting groove 11. Each of the four sliders 3 has two symmetrically distributed mounting holes 31 longitudinally arranged inside. A spring 4 connected to the inner top surface of the mounting groove 11 is installed inside each mounting hole 31. The sliders 3 can be telescopically moved inside the mounting groove 11 by the springs 4. The external structure of the strap 2 in this embodiment is a conventional and general structure. Only part of the structure is shown in Figure 1 of this application, and will not be described in detail here.

[0035] A first connecting rod 5 is connected between two sliders 3 located at the left and right ends inside the mounting groove 11. A second connecting rod 6 and a third connecting rod 7 connected to the first connecting rod 5 are respectively provided on the opposite surfaces of the two sliders 3 located at the front and rear ends inside the mounting groove 11. A first hanging ring 61 and a second hanging ring 71 with an integral structure are respectively provided below the second connecting rod 6 and the third connecting rod 7.

[0036] Inside the sole 1, two first support rods 8 and 9, which are matched with the first hanging ring 61 and the second hanging ring 71, are arranged parallel to each other on both sides of the first connecting rod 5. The second connecting rod 6 and the third connecting rod 7 are respectively fitted onto the first support rod 8 and the second support rod 9 through the first hanging ring 61 and the second hanging ring 71 below. The second connecting rod 6 and the first support rod 8, and the third connecting rod 7 and the second support rod 9 respectively form a lever structure.

[0037] Please see Figure 4 The inner side of the mounting groove 11 is provided with a sliding groove 12 that matches the position of the slider 3. The slider 3 moves up and down inside the mounting groove 11 along the sliding groove 12.

[0038] Please see Figure 4 The top surface of the slider 3 has a through hole 32 that matches the spring 4. One end of the spring 4 extends through the through hole 32 to the outside of the slider 3 and is connected to the top surface inside the mounting groove 11. The other end of the spring 4 is fixed to the bottom surface inside the mounting hole 31.

[0039] Please see Figure 9 The second connecting rod 6 is provided with a first arc-shaped hook 62 with a groove 63 in the middle at one end near the first connecting rod 5. The second connecting rod 6 is engaged with the outer periphery of the first connecting rod 5 through the first arc-shaped hook 62 at the end.

[0040] The diameter of the third connecting rod 7 is the same as the width of the groove 63 at one end of the second connecting rod 6. The third connecting rod 7 is provided with a second arc-shaped hook 72 at one end near the first connecting rod 5. The third connecting rod 7 is located at one end of the second arc-shaped hook 72, which extends into the groove 63 located in the middle of the first arc-shaped hook 62 on the second connecting rod 6 and is engaged with the outer periphery of the first connecting rod 5.

[0041] Please see Figure 1 The shoe sole 1 has a first through hole 13 and a second through hole 14 on one end of the first support rod 8 and the second support rod 9, respectively, which are matched with the outer diameter of the first support rod 8 and the second support rod 9. Both the first through hole 13 and the second through hole 14 extend into the inside of the shoe sole 1.

[0042] The first support rod 8 and the second support rod 9 extend through the first through hole 13 and the second through hole 14, through the first hanging ring 61 and the second hanging ring 71, and into the inside of the sole 1, and are movably connected to the first hanging ring 61 and the second hanging ring 71.

[0043] Please see Figure 1 The interior of the sole 1, located outside the mounting groove 11, has a grid-like hollow structure. An insole 14 is provided on the top surface of the sole 1 above the grid-like hollow structure. The insole 14 is fixed to the surface of the sole 1 by adhesive. In this embodiment, the sole 1 is made of high-molecular polyester material.

[0044] Please see Figure 2 The bottom surface of the slider 3 is provided with a rubber buffer pad 10, which is fixed to the bottom surface of the slider 3 by adhesive.

[0045] Please see Figure 1 The outer surface of the slider 3 is either square or arc-shaped; in this embodiment, the outer surfaces of the sliders at the front and rear ends are square, and the outer surfaces of the sliders at the left and right ends are arc-shaped.

[0046] In this embodiment, the first connecting rod 5, the second connecting rod 6, the third connecting rod 7, the first support rod 8, the second support rod 9, and the four sliders 3 are all made of stainless steel.

[0047] Among them, the first connecting rod 5, the second connecting rod 6, the third connecting rod 7 and the corresponding slider 3 are all fixedly connected by welding.

[0048] Working principle: When inspectors climb onto the steel reinforcement panel for inspection, firstly, anti-slip safety shoe covers are secured to the inspectors' shoes using two sets of straps 2. Because the cross intersections on the steel reinforcement panel of the building project are formed by two steel bars overlapping in a cross shape (e.g., ... Figure 10As shown), when the inspector, wearing safety shoe covers, walks on the cross-shaped section of the steel reinforcement panel, the installation groove 11 of the cross-shaped structure on the bottom of the shoe sole 1 is aligned with the cross-shaped lapped steel reinforcement 100 at the cross-shaped section as the inspector walks on the steel reinforcement panel.

[0049] Since a slider 3 is installed at each of the four ports of the mounting slot 11, the slider 3 can move along the mounting slot 11.

[0050] The inner side of the sliding groove 12 moves up and down. When the four sliders 3 in the mounting groove 11 on the bottom surface of the shoe sole 1 contact the surface of the reinforcing bar, under the pressure of the inspector's center of gravity, the sliders 3 move up along the sliding groove 12 on the inner side of the mounting groove 11, and the reinforcing bar is inserted into the mounting groove 11. Since a set of symmetrically distributed mounting holes 31 are arranged longitudinally on the sliders 3, and a spring 4 connected to the inner top surface of the mounting groove 11 is installed inside the mounting holes 31, the spring force of the spring 4 can accurately clamp onto the surface of the reinforcing bar. Since the two reinforcing bars that intersect in a cross shape are not on the same horizontal plane, in order to ensure that all four sliders 3 on the shoe sole can be clamped onto the intersecting reinforcing bars, a second connecting rod 6 and a third connecting rod 7 are welded to the opposite surfaces of the sliders 3 at the front and rear ends of the bottom of the shoe sole 1, respectively. The first hanging ring 61 and the second hanging ring 71 located below the second connecting rod 6 and the third connecting rod 7 inside the shoe sole are connected to the reinforcing bars. A first support rod 8 and a second support rod 9 are installed respectively. The first support rod 8 and the second support rod 9 form a lever structure with the second connecting rod 6 and the third connecting rod 7 respectively. In addition, a first connecting rod 5 is connected between the two sliders 3 on the left and right sides of the bottom surface of the sole 1 and is connected to the other end of the second connecting rod 6 and the third connecting rod 7. Utilizing the lever principle, when the sliders 3 at the front and rear ends of the sole 1 are locked with the overlapping top steel bar, the sliders 3 move upward, causing the other ends of the second connecting rod 6 and the third connecting rod 7 to press down the first connecting rod 5 and move downward, thereby locking the sliders 3 at the left and right ends of the sole 1 onto the overlapping bottom steel bar surface. When the inspector walks on the steel bar panel, he only needs to place the cross-shaped mounting groove 11 on the bottom surface of the sole at the intersection of the overlapping steel bar panel, which can effectively increase the contact area between the user's foot and the steel bar surface and protect the user's personal safety.

[0051] To facilitate fixing the other ends of the second connecting rod 6 and the third connecting rod 7 to the first connecting rod 5, the ends of the second connecting rod 6 and the third connecting rod 7 near the first connecting rod 5 are designed with a first arc-shaped hook 62 and a second arc-shaped hook 72 that match the outer diameter of the first connecting rod 5. A groove 63 matching the second arc-shaped hook 72 is provided on the first arc-shaped hook 62 at the position corresponding to the second arc-shaped hook 72, which is more conducive to installing the other ends of the second connecting rod and the third connecting rod onto the first connecting rod 5. In addition, a buffer pad 10 is provided on the bottom surface of the slider 3, which effectively increases the friction between the slider 3 and the steel bar surface, further playing an anti-slip role.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
