[0001] The invention relates to the technical field of bonded steel reinforcement structures, in particular to a bonded steel reinforcement structure and an implementation method thereof. Background Art

[0002] Bonded steel reinforcement technology is an effective structural reinforcement method. By bonding steel plates on the surface of concrete components, the bonding force of the adhesive is used to connect the steel plates and concrete into a whole, thereby improving the bearing capacity and rigidity of the structure. At present, this technology has been widely used in the reinforcement and reconstruction projects of various building structures.

[0003] However, some bonded steel reinforcement structures will have errors when the steel plates are glued and installed on the concrete components, and the pressure effect between some bonded steel plates and concrete components is cumbersome, making it impossible for the bonding layer to effectively bond the steel plates; therefore, it does not meet the existing needs.

[0007] Preferably, one end of the connecting sleeve away from the limiting plate is rotatably connected to a first threaded sleeve via a rotating shaft, and the first threaded sleeve is threadedly connected to the outer surface of the threaded rod.

[0008] Preferably, a second threaded sleeve is threadedly connected to the outer surface of the semi-threaded rod at a side of the steel plate away from the concrete member.

[0009] Preferably, a long groove is opened inside the upper end of the semi-threaded rod, and the long groove is movably connected inside a long rod that extends through and extends to the outside of the top end of the semi-threaded rod. The bottom end of the long groove is connected to a connecting groove located inside the semi-threaded rod, and the width of the connecting groove is smaller than the width of the long groove.

[0010] Preferably, the bottom end of the long rod is fixedly connected to a connecting rod that movably extends through the connecting groove, a spring is fixedly connected between the bottom end of the long rod and the bottom end of the long groove, and the spring is wound around the outer surface of the connecting rod.

[0011] Preferably, symmetrical side grooves are provided on both sides of the semi-threaded rod near the bottom end and on the side of the concrete member away from the steel plate, and the bottom ends of the two side grooves are hinged with limit rods, the limit rods are L-shaped, and the upper ends of the limit rods extend obliquely to the outside of the side grooves, and the upper ends of the limit rods abut against the side of the concrete member away from the steel plate.

[0012] Preferably, grooves are provided on both sides of the long rod near the bottom end, the bottom ends of the two side grooves close to each other are connected to the interior of the long groove, and one side of the bottom end of the limit rod extends into the interior of the long groove and is clamped in the corresponding groove.

[0013] Preferably, the steel plate adopts a composite steel plate structure, which is composited by a stainless steel plate and a high-strength steel plate through bonding or welding, and the bonding layer is an epoxy resin adhesive.

[0014] A method for implementing a steel-bonded reinforcement structure comprises the following steps:

[0015] Step 1: First, clean the surface of the concrete component to make it rough, then adjust the two limit plates according to the width of the concrete component, rotate the first threaded sleeve so that the first threaded sleeve thread rotates on the outer surface of the threaded rod, and then drive the limit block at one end of the threaded rod to slide along the inside of the connecting sleeve, so as to adjust the distance between the two limit plates according to the width of the concrete component, so that the two limit plates are clamped on both sides of the concrete component, and then add a layer of permeability enhancement layer to the cleaned surface of the concrete component, and then apply the bonding layer on the permeability enhancement layer, and finally slide the steel plate between the two limit plates and place it on the upper end of the concrete component and the bonding layer, so that the first through hole of the concrete component corresponds to the second through hole of the steel plate;

[0016] Step 2: The semi-threaded rod is passed through the second through hole and the first through hole in sequence, and is arranged outwardly at an angle through the limiting rod. When the limiting rod is located inside the second through hole and the first through hole, the inner walls of the second through hole and the first through hole push the limiting rod to move and shrink to the inside of the side groove. After the limiting rod passes through the first through hole, the upper end of the limiting rod moves out of the side groove and abuts against the side of the concrete member away from the steel plate. Then, by rotating the second threaded sleeve, the second threaded sleeve is threadedly rotated on the semi-threaded rod and approaches the steel plate.

[0017] Step 3: When the bonding layer between the steel plate and the concrete component is solidified, push the long rod to drive the connecting rod to move downward, so that one end of the connecting rod moves and extends to the inside of the connecting groove, and squeezes the spring to compress. At this time, the long rod drives the groove to move downward during the movement, so that the top of the inner wall of the groove squeezes the limit rods on both sides to move and shrink to the inside of the side groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention rotates the first threaded sleeve so that the first threaded sleeve thread rotates on the outer surface of the threaded rod, and then drives the limit block at one end of the threaded rod to slide along the inside of the connecting sleeve, so as to adjust the distance between the two limit plates according to the width of the concrete component, so that the two limit plates are clamped on both sides of the concrete component, and then the steel plate is slidably clamped between the two limit plates and placed on the upper end of the concrete component and the bonding layer, so that the first through hole of the concrete component corresponds to the second through hole of the steel plate, thereby avoiding errors when the concrete component and the steel plate are pasted and installed;

[0020] 2. The present invention allows the semi-threaded rod to pass through the second through hole and the first through hole in sequence, and the limiting rod is arranged to be inclined outward. When the limiting rod is located inside the second through hole and the first through hole, the inner walls of the second through hole and the first through hole push the limiting rod to move and shrink to the inside of the side groove. After the limiting rod passes through the first through hole, the upper end of the limiting rod moves out of the side groove and abuts against the side of the concrete component away from the steel plate. Then, by rotating the second threaded sleeve, the second threaded sleeve is threadedly rotated on the semi-threaded rod and close to the steel plate, thereby cooperating with the limiting rod to squeeze the steel plate close to the concrete component, and applying appropriate pressure to fit the steel plate onto the bonding layer to ensure firm adhesion.

[0021] 3. After the bonding layer between the steel plate and the concrete member is cured, the present invention pushes the long rod to drive the connecting rod to move downward, so that one end of the connecting rod moves and extends to the inside of the connecting groove, and the spring is compressed. At this time, the long rod drives the groove to move downward during the movement, so that the top end of the inner wall of the groove squeezes the limit rods on both sides to move and shrink to the inside of the side groove, thereby releasing the abutment against the concrete member and taking the long rod out from the first through hole and the second through hole.

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figures 1 to 6 The present invention provides an embodiment: a steel-bonded reinforcement structure, comprising a concrete component 1 and a steel plate 2, wherein the steel plate 2 is arranged on one side of the concrete component 1, and an adhesive layer 3 is applied between the sides of the concrete component 1 and the steel plate 2 where they are close to each other, and both sides of the concrete component 1 and the steel plate 2 are adjustable and provided with limit plates 4, and the sides of the two limit plates 4 where they are close to each other are both fitted with the two sides of the concrete component 1 and the steel plate 2, first through holes 101 are opened at the diagonals of the concrete component 1, and second through holes 201 corresponding to the first through holes 101 are opened at the diagonals of the steel plate 2, and a semi-threaded rod 10 is penetrated and connected between each corresponding first through hole 101 and the second through hole 201.

[0031] One side of one of the limit plates 4 is fixedly connected to a connecting sleeve 6, and the other limit plate 4 is fixedly connected to a threaded rod 5 extending into the interior of the connecting sleeve 6 on one side close to the connecting sleeve 6, and one end of the threaded rod 5 extending into the interior of the connecting sleeve 6 is fixedly connected to a limit block 7 slidably connected to the interior of the connecting sleeve 6, and the end of the connecting sleeve 6 away from the limit plate 4 is rotatably connected to a first threaded sleeve 9 through a rotating shaft 8, and the first threaded sleeve 9 is threadedly connected to the outer surface of the threaded rod 5.

[0032] By rotating the first threaded sleeve 9, the first threaded sleeve 9 is threadedly rotated on the outer surface of the threaded rod 5, and then the limit block 7 at one end of the threaded rod 5 is driven to slide along the inside of the connecting sleeve 6, so that the distance between the two limit plates 4 is adjusted according to the width of the concrete component 1, so that the two limit plates 4 are clamped on both sides of the concrete component 1, thereby avoiding errors when the concrete component 1 and the steel plate 2 are pasted and installed.

[0033] The steel plate 2 adopts a composite steel plate structure, which is composed of a stainless steel plate and a high-strength steel plate through bonding or welding. The stainless steel plate provides good corrosion resistance, and the high-strength steel plate provides high-strength bearing performance, which together improve the durability and reliability of the reinforced structure. The bonding layer 3 is an epoxy resin adhesive, which can adapt to different construction environments and requirements. By adding nano-reinforcement materials such as nano-silicon dioxide to the bonding layer 3, the excellent performance of the nano-materials can be used to improve the bonding strength and durability of the bonding layer 3, while reducing dependence on environmental conditions.

[0034] The outer surface of the semi-threaded rod 10 is threadedly connected with a second threaded sleeve 11 on the side of the steel plate 2 away from the concrete member 1. A long groove 1001 is opened inside the upper end of the semi-threaded rod 10. The long groove 1001 is movably connected with a long rod 12 extending through and extending to the outside of the top of the semi-threaded rod 10. The bottom end of the long groove 1001 is connected with a connecting groove 1003 located inside the semi-threaded rod 10, and the width of the connecting groove 1003 is smaller than the width of the long groove 1001. The bottom end of the long rod 12 is fixedly connected with a movable connecting rod 12 extending through and extending to the inside of the connecting groove 1003. A spring 15 is fixedly connected between the bottom end of the connecting rod 14 and the bottom end of the long rod 12, and the spring 15 is wound around the outer surface of the connecting rod 14. Symmetrical side grooves 1002 are provided on both sides of the semi-threaded rod 10 close to the bottom end and on the side of the concrete component 1 away from the steel plate 2. The bottom ends of the two side grooves 1002 are hinged with a limiting rod 13, which is L-shaped, and the upper end of the limiting rod 13 extends obliquely to the outside of the side groove 1002, and the upper end of the limiting rod 13 abuts against the side of the concrete component 1 away from the steel plate 2.

[0035] By rotating the second threaded sleeve 11, the second threaded sleeve 11 is threadedly rotated on the semi-threaded rod 10 and close to the steel plate 2, thereby cooperating with the limiting rod 13 to squeeze the steel plate 2 close to the concrete member 1, and applying appropriate pressure to adhere the steel plate 2 to the bonding layer 3 to ensure firm adhesion.

[0036] Grooves 1201 are provided on both sides of the long rod 12 near the bottom end, and the bottom ends of the sides of the two side grooves 1002 close to each other are connected to the inside of the long groove 1001. One side of the bottom end of the limiting rod 13 extends through the inside of the long groove 1001 and is clamped in the corresponding groove 1201. By pushing the long rod 12, the groove 1201 is driven to move downward during the movement of the long rod 12, so that the top end of the inner wall of the groove 1201 squeezes the limiting rods 13 on both sides to move and shrink to the inside of the side groove 1002, thereby releasing the abutment against the concrete component 1 and taking the long rod 12 out of the first through hole 101 and the second through hole 201.

[0037] The implementation method of the above-mentioned bonded steel reinforcement structure comprises the following steps:

[0038] Step 1: First, clean the surface of the concrete component 1 to make it rough, then adjust the two limit plates 4 according to the width of the concrete component 1, rotate the first threaded sleeve 9 so that the first threaded sleeve 9 is threadedly rotated on the outer surface of the threaded rod 5, and then drive the limit block 7 at one end of the threaded rod 5 to slide along the inside of the connecting sleeve 6, so as to adjust the distance between the two limit plates 4 according to the width of the concrete component 1, so that the two limit plates 4 are clamped on both sides of the concrete component 1, and then a layer of permeability enhancement layer is added to the surface of the cleaned concrete component 1, and then the bonding layer 3 is applied on the permeability enhancement layer, and finally the steel plate 2 is slidably clamped between the two limit plates 4 and placed on the upper end of the concrete component 1 and the bonding layer 3, so that the first through hole 101 of the concrete component 1 corresponds to the second through hole 201 of the steel plate 2;

[0039] Step 2: The semi-threaded rod 10 is passed through the second through hole 201 and the first through hole 101 in sequence, and the limiting rod 13 is arranged to be inclined outward. When the limiting rod 13 is located inside the second through hole 201 and the first through hole 101, the inner walls of the second through hole 201 and the first through hole 101 push the limiting rod 13 to move and shrink to the inside of the side groove 1002. After the limiting rod 13 passes through the first through hole 101, the upper end of the limiting rod 13 moves out of the side groove 1002 and abuts against the side of the concrete member 1 away from the steel plate 2. Then, by rotating the second threaded sleeve 11, the second threaded sleeve 11 is threadedly rotated on the semi-threaded rod 10 and approaches the steel plate 2.

[0040] Step three: After the bonding layer 3 between the steel plate 2 and the concrete member 1 is cured, the long rod 12 is pushed to drive the connecting rod 14 to move downward, so that one end of the connecting rod 14 moves and extends to the inside of the connecting groove 1003, and the squeezing spring 15 is compressed. At this time, the long rod 12 drives the groove 1201 to move downward during the movement, so that the top end of the inner wall of the groove 1201 squeezes the limit rods 13 on both sides to move and shrink to the inside of the side groove 1002.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
