Description

Technical Field

[0001] This application relates to the field of construction design for splicing and extending steel reinforcement cages, specifically to a steel reinforcement cage splicing guide device and a steel reinforcement cage splicing system. Background Technology

[0002] With the advancement of science and technology and the rapid development of transportation infrastructure, bridge construction has made great strides. In the construction of steel reinforcement cages for bridge engineering or pile foundation engineering, the precise connection of the upper and lower steel reinforcement cages is a key technology. Whether the upper and lower steel reinforcement cages can be precisely connected has a great impact on the subsequent concrete pouring and the quality of the finished product.

[0003] In related technologies, when connecting the upper rebar cage, which is a rebar cage to be extended, to the lower rebar cage, which is a reserved joint of a rebar cage that has been installed or poured, a crane is usually used to lift the upper rebar cage above the lower rebar cage. Each rebar is then manually connected to the correct position one by one. After that, the sleeve is screwed into the lower and upper rebar cages respectively, and the upper and lower rebar cages are connected into a whole using the sleeve.

[0004] However, using only sleeves to connect the upper and lower steel reinforcement cages makes the upper steel reinforcement cage, which is lifted by a crane, susceptible to slight swaying due to wind force and lifting point deviation. Manual adjustment of the position of individual steel bars is required before inserting the sleeve, making the connection time-consuming. Summary of the Invention

[0005] This application provides a rebar cage docking guide device and a rebar cage docking system, which can solve the technical problems in related technologies where the docking of upper and lower rebar cages is only achieved by using sleeves. The upper rebar cage hoisted by the crane is easily affected by wind force and hoisting point deviation, resulting in slight swaying. Manual adjustment of the position of individual rebars is required before inserting them into the sleeve, which is time-consuming.

[0006] In a first aspect, embodiments of this application provide a rebar cage docking guide device, comprising: a connecting operation mechanism for connecting to a rebar, the connecting operation mechanism having a rebar receiving cavity, a first operating groove being provided on the side wall of the connecting operation mechanism, the rebar receiving cavity communicating with the outside through the first operating groove; and a tapered guide portion connected to the connecting operation mechanism, the tapered guide portion having an inlet cavity, the inlet cavity being coaxially arranged with the rebar receiving cavity, and the inlet cavity communicating with the rebar receiving cavity.

[0007] In conjunction with the first aspect, in one embodiment, the connecting operation mechanism includes: a connecting fixing part having a rebar fixing cavity; an operating part connected to the connecting fixing part, the rebar receiving cavity being opened in the operating part and communicating with the rebar fixing cavity, the operating part being sandwiched between the connecting fixing part and the conical guide part, and the first operating groove being opened in the side wall of the operating part.

[0008] In conjunction with the first aspect, in one embodiment, the tapered guide portion includes a tapered segment and a connecting segment fixed to the tapered segment. The tapered segment is fixed to one end of the connecting segment away from the operating portion. The inner sidewall of the connecting segment is provided with a first connecting thread, and the outer periphery of the operating portion is provided with a second connecting thread that mates with the first connecting thread.

[0009] In conjunction with the first aspect, in one embodiment, the connecting and fixing part includes a first connecting member and a second connecting member, the first connecting member and the second connecting member forming the rebar fixing cavity, and the first connecting member and the second connecting member being movably connected; the operating part includes a first operating member, the first operating member being fixed to the first connecting member, the operating part further including a second operating member fixed to the second connecting member, the first operating member and the second operating member forming the rebar receiving cavity, and the second operating member being movably connected, the first operating member having a first operating groove.

[0010] In conjunction with the first aspect, in one embodiment, the side wall of the second operating member is provided with a second operating groove, which communicates with the steel bar receiving cavity.

[0011] In conjunction with the first aspect, in one embodiment, one side of the first operating member is connected to the second operating member via a hinge mechanism, and the other side is detachably connected to the second operating member via a first connecting assembly.

[0012] In conjunction with the first aspect, in one embodiment, the tapered guide portion includes: a first guide member and a second guide member, the first guide member and the second guide member forming the inlet cavity; and a second connecting assembly, the first guide member and the second guide member being detachably connected via the second connecting assembly.

[0013] In conjunction with the first aspect, in one embodiment, the second connecting component includes: a first connecting block, the first connecting block being fixed to the first guide member, the first connecting block having a first through hole; a second connecting block, the second connecting block being fixed to the second guide member, the second connecting block having a second through hole; and a connecting bolt, the connecting bolt passing through the first through hole and the second through hole, and one end of the connecting bolt being fitted with a connecting nut.

[0014] Secondly, embodiments of this application provide a rebar cage docking system, which includes the rebar cage docking guide device as described above. The rebar cage docking system further includes a sleeve for connecting to the rebar, and the sleeve is housed in the rebar receiving cavity, wherein the outer diameter of the sleeve is smaller than the inner diameter of the rebar receiving cavity.

[0015] The beneficial effects of the technical solutions provided in this application include: The guide device is connected to the lower reinforcing bar by connecting the operating mechanism, so that part of the lower reinforcing bar is located in the reinforcing bar receiving cavity, and part of the upper reinforcing bar can be hoisted into the inlet cavity of the conical guide, and part of it can also be located in the reinforcing bar receiving cavity. Then, the sleeve is extended into the reinforcing bar receiving cavity from the first operating groove to connect the upper and lower reinforcing bars. It should be understood that the conical guide and the connecting operating mechanism can work together to play a certain limiting role for the upper reinforcing bar, reducing its influence from wind force or hoisting point deviation. This solves the problem in related technologies that the upper reinforcing bar is easily affected by wind force and hoisting point deviation, and that manual adjustment of the position of a single reinforcing bar is required repeatedly before inserting the sleeve, resulting in long connection time.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0020] This application provides a rebar connection guide device, which can solve the technical problems in related technologies where the connection of upper and lower rebars is only achieved through a sleeve. The upper rebars lifted by the crane are easily affected by wind force and lifting point deviation, resulting in slight swaying. Manual adjustment of the position of a single rebar is required repeatedly before it can be inserted into the sleeve, which is time-consuming.

[0021] See Figure 1 The diagram illustrates a rebar connection guide device provided in this application embodiment. It may include: a connecting operating mechanism for connecting to the rebar, the connecting operating mechanism having a rebar receiving cavity 121, and a first operating groove 1231 formed on the side wall of the connecting operating mechanism, the rebar receiving cavity 121 communicating with the outside through the first operating groove 1231; and a tapered guide portion 2 connected to the connecting operating mechanism, the tapered guide portion 2 having an inlet cavity 21, the inlet cavity 21 being coaxially arranged with the rebar receiving cavity 121 and communicating with the rebar receiving cavity 121. It should be understood that in specific use, the connecting operating mechanism should be connected to the lower rebar, and the tapered guide portion 2 is indirectly connected to the lower rebar through the connecting operating mechanism. The tapered guide portion 2 has a tapered structure, with the inner diameter of the end of the tapered guide portion 2 away from the connecting operating mechanism being larger than the inner diameter of the end closest to the connecting operating mechanism, facilitating the upper rebar to extend into the rebar receiving cavity 121 from the tapered guide portion 2. It should be noted that in the embodiments of this application, the upper reinforcing bar refers to one of the reinforcing bars in the upper reinforcing bar cage, and the lower reinforcing bar refers to one of the reinforcing bars in the lower reinforcing bar cage.

[0022] In this embodiment, the guiding device is connected to the lower reinforcing bar via a connecting operating mechanism, so that a portion of the lower reinforcing bar is located in the reinforcing bar receiving cavity 121. A portion of the upper reinforcing bar can be hoisted into the inlet cavity 21 of the conical guide 2, and a portion of it can also be located within the reinforcing bar receiving cavity 121. The inlet cavity 21 of the conical guide 2 is flared, which can significantly expand the access range of the upper reinforcing bar. Even if the upper reinforcing bar hoisted by the crane sways due to wind or hoisting point deviation, it can still be guided by the cavity wall of the conical guide 2 to a coaxial area with the lower reinforcing bar. The inlet cavity 21 and the reinforcing bar receiving cavity of the connecting operating mechanism are connected. The cavity 121 is coaxially connected, allowing the upper reinforcing bar, guided by a guide, to directly enter the cavity for initial positioning, reducing repeated manual adjustments. Subsequently, a sleeve is inserted into the reinforcing bar cavity 121 from the first operating groove 1231 to connect the upper and lower reinforcing bars. The inner diameter of the reinforcing bar cavity 121 should be larger than the outer diameter of the sleeve, and the length of the first operating groove 1231 along the reinforcing bar axial direction should be greater than the length of the sleeve to avoid affecting subsequent sleeve screwing operations. This ensures that when the sleeve is screwed along the reinforcing bar axial direction, there is sufficient space to avoid obstruction by the first operating groove 1231, allowing for smooth connection with the upper and lower reinforcing bars. In this embodiment, the tapered guide 2 and the connecting operating mechanism can cooperate to provide a certain limiting effect on the upper reinforcing bar, reducing its susceptibility to wind or lifting point deviation. This solves the problem in related technologies where the upper reinforcing bar is easily affected by wind and lifting point deviation, requiring repeated manual adjustments to the position of individual reinforcing bars before inserting the sleeve, resulting in long connection times.

[0023] In some optional embodiments, the connecting operation mechanism may include: a connecting fixing part 11 having a rebar fixing cavity; an operating part 12 connected to the connecting fixing part 11, a rebar receiving cavity 121 formed in the operating part 12 and communicating with the rebar fixing cavity; the operating part 12 being sandwiched between the connecting fixing part 11 and the conical guide part 2; and a first operating groove 1231 formed in the side wall of the operating part 12. In this embodiment, the connecting fixing part 11 can be fixed to the lower rebar, which is located in the rebar fixing cavity. A portion of the lower rebar extends from the rebar fixing cavity into the rebar receiving cavity 121. Because the conical guide part 2 is connected to the end of the operating part 12 away from the connecting fixing part 11, and the guide cavity 21 communicates with the rebar receiving cavity 121, after a portion of the upper rebar extends into the guide cavity 21, one end of the lower rebar and one end of the upper rebar can approach each other. Specifically, when using a sleeve to connect upper and lower reinforcing bars, threads can be made at both ends of the upper reinforcing bar near the lower reinforcing bar, so that the upper and lower reinforcing bars are threadedly connected to the sleeve. In this embodiment, the sleeve can be used by first fixing the connecting fixing part 11 to the lower reinforcing bar with one end threaded. The operator can observe the specific position from the first operating groove 1231 and make the threaded part of the lower reinforcing bar extend into the reinforcing bar receiving cavity 121. Then, the upper reinforcing bar skeleton is hoisted, and the corresponding upper reinforcing bar in the upper reinforcing bar skeleton that needs to be connected with the lower reinforcing bar is inserted from the opening of the conical guide part 2. At this time, the threaded end of the upper reinforcing bar is close to the threaded end of the lower reinforcing bar, but the two are still separated from each other. Then, the sleeve is inserted into the reinforcing bar receiving cavity 121 from the first operating groove 1231 and screwed between the upper and lower reinforcing bars. There should be operating space for screwing tools, such as wrench, between the inner wall of the reinforcing bar receiving cavity 121 and the outer wall of the sleeve.

[0024] In this embodiment, under the guidance of the tapered guide 2, even if the lifting point of the upper reinforcing bar has a certain deviation during hoisting, it can still extend from the tapered guide 2 into the inlet cavity 21 and partially into the reinforcing bar receiving cavity 121. At this time, the upper reinforcing bar is initially positioned under the joint limitation of the operating part 12 and the tapered inlet cavity 21, reducing the manual repeated adjustment of the position of the upper reinforcing bar, quickly completing the initial positioning, improving the docking efficiency, and laying a precise foundation for subsequent sleeve connection. Preferably, the bottom of the threaded area of ​​the lower reinforcing bar is at the same level as the bottom edge of the first operating groove 1231, so that the operator can clearly observe the fit between the threaded area of ​​the lower reinforcing bar and the sleeve when screwing the sleeve, and the sleeve screwing process is not obstructed by the first operating groove 1231, so that the threaded connection with the threaded area of ​​the lower reinforcing bar can be completed smoothly.

[0025] In some optional embodiments, the tapered guide 2 is detachably connected to the operating part 12. It should be understood that the detachable connection of the tapered guide 2 to the operating part 12 facilitates the replacement of the appropriate tapered guide 2 according to the diameter of the reinforcing bar, improving the versatility of the device. In addition, during construction, the tapered guide 2 may deform or wear its port due to excessive deviation when hoisting the reinforcing bar, causing the reinforcing bar to violently impact the inner wall or port of the tapered guide 2. The detachable connection between the tapered guide 2 and the operating part 12 allows for individual replacement of the tapered guide 2 after it is damaged, reducing maintenance costs and facilitating transportation and storage.

[0026] In some optional embodiments, the tapered guide portion 2 includes a tapered segment and a connecting segment 23 fixed to the tapered segment. The tapered segment is fixed to the end of the connecting segment 23 away from the operating part 12. The inner sidewall of the connecting segment 23 is provided with a first connecting thread 231, and the outer periphery of the operating part 12 is provided with a second connecting thread 122 that mates with the first connecting thread 231. That is, the operating part 12 and the tapered guide portion 2 can be detachably connected by a threaded connection. The engagement of the first connecting thread 231 and the second connecting thread 122 ensures that the tapered guide portion 2 and the operating part 12 are precisely aligned and firmly connected. The threaded connection also allows for quick connection. It should be understood that the tapered segment tapers uniformly from the end away from the operating part 12 to the end closer to the operating part 12, while the connecting segment 23 is cylindrical with the same diameter at all heights to achieve alignment with the operating part 12.

[0027] See Figure 4As shown, in some other embodiments, the connecting and fixing part 11 includes a first connecting member 112 and a second connecting member 113, the first connecting member 112 and the second connecting member 113 forming the steel bar fixing cavity, and the first connecting member 112 and the second connecting member 113 are movably connected; the operating part 12 includes a first operating member 123, the first operating member 123 is fixed to the first connecting member 112, the operating part 12 also includes a second operating member 124 fixed to the second connecting member 113, the first operating member 123 and the second operating member 124 form the steel bar receiving cavity 121, and the second operating member 124 is movably connected to the first operating member 123, and the first operating member 123 has a first operating groove 1231. That is, the first connector 112 and the second connector 113 are separate designs, as are the first operating component 123 and the second operating component 124. Specifically, the first connector 112 and the first operating component 123 are fixed to each other and integrally formed, and the second connector 113 and the second operating component 124 are fixed to each other and integrally formed. Integral forming can reduce splicing gaps, improve overall strength, and reduce positioning deviations caused by loose connections under stress. Through the movable connection of the first connector 112 and the second connector 113, and the movable connection of the second operating component 124, the connecting fixing part 11 and the operating part 12 can be quickly installed and disassembled. Especially during disassembly, it is not necessary to remove the connecting fixing part 11 and the operating part 12 as a whole from the end of the upper reinforcing bar. The device can be disassembled by directly opening and closing the component laterally, saving construction time. At the same time, the connecting fixing part 11 and the operating part 12 can also be used for the construction of the next segment of the reinforcing bar skeleton, realizing the reverse use of the device and saving construction costs.

[0028] See Figure 3 As shown, in some optional embodiments, the second operating member 124 has a second operating groove 1241 on its side wall, and the second operating groove 1241 communicates with the rebar receiving cavity 121. Preferably, the first operating groove 1231 and the second operating groove 1241 are arranged on opposite sides of the operating member along the axis of the rebar receiving cavity 121, so as to form a symmetrical operating space on the side wall of the operating part 12. This avoids the sleeve being blocked by the cavity wall when it is screwed due to the single-sided slot. Moreover, the cooperation of the first operating groove 1231 and the second operating groove 1241 allows the operator to apply force from both sides of the rebar at the same time or work alternately. Especially for large-diameter and long threaded sleeves, the cooperation of both sides can improve the screwing stability and connection efficiency.

[0029] In some optional embodiments, one side of the first operating member 123 is connected to the second operating member 124 via a hinge mechanism 125, and the other side is detachably connected to the second operating member 124 via a first connecting assembly 126. Specifically, the first side of the first operating member 123 is hinged to the first side of the second operating member 124, and the second side of the second operating member 124 is detachably connected to the second side of the second operating member 124. Since the first connecting member 112 is fixed to the first operating member 123 and integrally formed, and the second connecting member 113 is fixed to the second operating member 124 and integrally formed, the opening and closing of the first connecting member 112 and the second connecting member 113 can be realized simultaneously through the hinged opening and closing and the detachable connection of the first operating member 123 and the second operating member 124, thereby quickly and laterally fitting or removing the lower reinforcing bar. This arrangement makes the device more flexible during installation and disassembly, and if the device position needs to be adjusted or components replaced laterally, it can also be conveniently operated by disassembling the first connecting assembly 126.

[0030] In some optional embodiments, the tapered guide portion 2 may include: a first guide member 24 and a second guide member 25, the first guide member 24 and the second guide member 25 forming the inlet cavity 21; and a second connecting assembly 26, the first guide member 24 and the second guide member 25 being detachably connected via the second connecting assembly 26. That is, the tapered guide portion 2 can be connected or disassembled via the cooperation of the first guide member 24 and the second guide member 25, enabling lateral application or disassembly to the reinforcing bar without needing to insert it from the end of the reinforcing bar. It can also be directly opened and closed laterally to achieve its own disassembly, saving construction time. Furthermore, it can be used for the construction of the next segment of the reinforcing bar skeleton, realizing the reusability of the device and saving construction costs.

[0031] See Figure 2As shown, in some optional embodiments, the second connecting component 26 may include: a first connecting block 261, fixed to the first guide member 24, the first connecting block 261 having a first through hole; a second connecting block 262, fixed to the second guide member 25, the second connecting block 262 having a second through hole; and a connecting bolt 263, passing through the first through hole and the second through hole, with a connecting nut 264 fitted at one end of the connecting bolt 263. Preferably, the first connecting block 261 is welded to the first guide member 24, and the second connecting block 262 is welded to the second guide member 25. The first connecting block 261 and the second connecting block 262 respectively have coaxial first and second through holes. After the connecting bolt 263 passes through the two through holes and is locked with the connecting nut 264, a detachable connection between the first guide member 24 and the second guide member 25 is achieved. Compared to connection methods such as snap-fit, the bolt-nut connection in this embodiment has adjustable locking force and strong anti-loosening ability, and can maintain the closed state of the guide member during long-term use or impact, thus ensuring guiding accuracy as much as possible. In this embodiment, the second connecting component 26 may include two sets, which are symmetrically arranged along the axis of the tapered guide portion 2, and both are used to connect the first guide member 24 and the second guide member 25. Preferably, the first connecting component 126 may have the same structure as the second connecting component 26, and the connecting blocks of the first connecting component 126 are welded and fixed to the first operating member 123 and the second operating member 124 respectively.

[0032] This application embodiment also includes a rebar cage docking system, which includes the rebar cage docking guide device as described above. The rebar cage docking system may further include: a sleeve for connecting to the rebar, and the sleeve is housed in the rebar receiving cavity 121, wherein the outer diameter of the sleeve is smaller than the inner diameter of the rebar receiving cavity 121. The rebar cage docking system may include the rebar cage docking guide device of any of the above embodiments, and will not be described again here.
