Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular, to a reinforcement positioning device for reinforced concrete pavement. Background Technology

[0002] In reinforced concrete pavements, unlike ordinary concrete pavements, steel bars need to be laid before pouring. The main function of the reinforcement is to control crack width, reduce reflective cracking, and improve overall load-bearing capacity. It is suitable for areas with heavy traffic, uneven foundation settlement, or large temperature differences. Specific functions include: limiting crack propagation, as steel bars can restrain concrete shrinkage cracks and prevent cracks from becoming too wide; improving flexural tensile strength, enhancing the pavement's ability to resist vehicle loads and temperature stress; reducing the number of joints, as the joint spacing can be appropriately increased compared to plain concrete pavements; and adapting to weak foundations: in cases of uneven foundation settlement, steel bars can disperse stress and prevent slab fracture.

[0003] However, when reinforcing concrete pavements, the reinforcing bars need to be accurately fixed to the installation points on the pavement using a positioning device. For example, the formwork device for continuously reinforced concrete pavements provided by Chinese utility model patent CN205382390U uses multiple reserved holes on the formwork body to position and support the reserved reinforcing bars. However, since the position of the formwork body is relatively fixed, it is difficult to flexibly adjust the support position according to the actual position and length of the reinforcing bars. If the positioning position is readjusted, the formwork body and a large number of related construction components need to be moved, which is inconvenient to use and has a significant impact on the reinforcement speed, reducing construction efficiency.

In two adjacent support mechanisms, the first end of the connecting rod is used to insert into the inner hole of the first or second connecting ring of one support mechanism, and the second end of the connecting rod is used to insert into the inner hole of the first or second connecting ring of the other support mechanism. The locking ring is used to connect with the outer circumferential thread of the first connecting ring when the connecting rod is inserted into the first connecting ring to drive the first connecting ring to contract and tighten the connecting rod along the movable notch.

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Those skilled in the art will understand that, unless specifically stated otherwise, the term "comprising" as used in this specification means the presence of the stated features, integers, steps, operations, components, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, components, components, and / or combinations thereof. It should be understood that when we say a component is "connected" to another component, it can be directly connected to the other component or connected via an intermediate component. The term "and / or" as used herein includes all or any unit and all combinations of one or more associated listed items. The terms "first" and "second," etc., in this specification and claims are used to distinguish different objects, not to describe a particular order.

[0031] Figures 1 to 3 The present invention provides a reinforced concrete pavement reinforcement positioning device, which is used to support and position the reinforcing bars in the reinforced concrete pavement reinforcement operation. It can flexibly adjust the positioning position to adapt to the positioning requirements of different reinforcing bars, improve the accuracy and efficiency of reinforced concrete pavement reinforcement, and can adapt to reinforcing bars of different diameters, making it highly applicable.

[0032] Please combine Figure 1 and Figure 2 The reinforced concrete pavement reinforcement positioning device 1000 includes multiple support mechanisms 1 arranged at intervals along the length of the reinforcing bars. Each support mechanism 1 includes a support base 11, an anti-slip sleeve 12, and a clamp assembly 13. The support base 11 has an installation hole 111 extending through it along the line connecting the multiple support mechanisms 1. The anti-slip sleeve 12 is detachably inserted into the installation hole 111, and a portion of the anti-slip sleeve 12 extends axially out of the installation hole 111. The anti-slip sleeve 12 is made of elastic materials such as rubber and silicone to provide better anti-slip effect. The inner hole of the anti-slip sleeve 12 is used to insert the reinforcing bars. The clamp assembly 13 is fitted onto the anti-slip sleeve 12 at the position where it extends out of the installation hole 111 and is used to clamp the anti-slip sleeve 12, thereby clamping and fixing the reinforcing bars through the anti-slip sleeve 12.

[0033] Specifically, the reinforced concrete pavement reinforcement positioning device 1000 supports the reinforcing bars through multiple support mechanisms 1. The specific number and position of each support mechanism 1 can be flexibly adjusted according to the length of the reinforcing bars to meet different positioning and support requirements, thereby ensuring positioning accuracy, facilitating quick insertion of reinforcing bars, and effectively improving reinforcement efficiency. Secondly, the support mechanism 1 includes a support base 11, an anti-slip sleeve 12, and a clamping assembly 13. The anti-slip sleeve 12 is installed in the mounting hole 111 of the support base 11. The reinforcing bar is inserted through the inner hole of the anti-slip sleeve 12, and then clamped by the clamping assembly 13 to achieve clamping and fixing of the reinforcing bar. The locking structure is simple and efficient. The anti-slip sleeve 12 not only prevents the reinforcing bar from slipping and improves the locking strength, but also allows for the replacement of anti-slip sleeves 12 with different inner diameters to accommodate reinforcing bars of different outer diameters, thereby supporting reinforcing bars of different specifications and effectively improving applicability.

[0034] like Figure 1 As shown, the reinforced concrete pavement reinforcement positioning device 1000 also includes a connecting component 2. The connecting component 2 is disposed between two adjacent support mechanisms 1 and connects the two adjacent support mechanisms 1 into a whole. In use, multiple support mechanisms 1 can be connected into a whole in sequence through the connecting component 2 to achieve mutual positioning and fixation of multiple support mechanisms 1, ensuring that multiple support mechanisms 1 are set in a straight line direction, and even if multiple anti-slip sleeves 12 are set coaxially, it is convenient to quickly insert the positioning reinforcement.

[0035] Please combine Figure 2 and Figure 3The support base 11 has a first connecting ring 112 and a second connecting ring 113 on opposite sides. Both the first connecting ring 112 and the second connecting ring 113 have external threads 114, and both the first connecting ring 112 and the second connecting ring 113 have multiple movable notches 115 spaced apart along the circumference.

[0036] Further, the connecting assembly 2 includes a connecting rod 21 and two locking rings 22 rotatably sleeved on opposite ends of the connecting rod 21. The locking rings 22 are provided with internal threads. In two adjacent support mechanisms 1, the first end of the connecting rod 21 is used to insert into the inner hole of the first connecting ring 112 or the second connecting ring 113 of one support mechanism 1, and the second end of the connecting rod 21 is used to insert into the inner hole of the first connecting ring 112 or the second connecting ring 113 of the other support mechanism 1. The locking rings 22 are used to be threadedly connected to the outer circumference of the first connecting ring 112 when the connecting rod 21 is inserted into the first connecting ring 112 to drive the first connecting ring 112 to contract and tighten the connecting rod 21 along the movable notch 115. The locking rings 22 are also used to be threadedly connected to the outer circumference of the second connecting ring 113 when the connecting rod 21 is inserted into the second connecting ring 113 to drive the second connecting ring 113 to contract and tighten the connecting rod 21 along the movable notch 115.

[0037] Specifically, both ends of the connecting rod 21 can be inserted into the first connecting ring 112 of each of two adjacent support mechanisms 1, and both ends of the connecting rod 21 can also be inserted into the second connecting ring 113 of each of two adjacent support mechanisms 1. Alternatively, the first end of the connecting rod 21 can be inserted into the first connecting ring 112 of one support mechanism 1, and the second end of the connecting rod 21 can be inserted into the second connecting ring 113 of the other support mechanism 1. That is, the support mechanism 1 can be positioned so that the first connecting ring 112 faces the first connecting ring 112 of the other support mechanism 1, and the support mechanism 1 can also be positioned so that the first connecting ring 112 faces the second connecting ring 113 of the other support mechanism 1. There is no restriction on the setting direction, which is convenient to use. Secondly, when the connecting rod 21 is inserted into the first connecting ring 112, the locking ring 22 can be threadedly connected to the outer periphery of the first connecting ring 112 to drive the first connecting ring 112 to contract and tighten the connecting rod 21 along the movable notch 115; similarly, when the connecting rod 21 is inserted into the second connecting ring 113, the locking ring 22 can be threadedly connected to the outer periphery of the second connecting ring 113 to drive the second connecting ring 113 to contract and tighten the connecting rod 21 along the movable notch 115. The locking structure is simple, efficient, and easy to assemble and disassemble.

[0038] Furthermore, the outer diameters of the first connecting ring 112 and the second connecting ring 113 gradually increase in the direction toward the support base 11, so that when the locking ring 22 is screwed into the first connecting ring 112 or the second connecting ring 113 through threaded engagement, it can drive the first connecting ring 112 or the second connecting ring 113 to contract and tighten the connecting rod 21 along the movable notch 115. In other embodiments, the inner diameter of the locking ring 22 can also be set to gradually decrease in the direction toward the support base 11, which similarly allows the first connecting ring 112 or the second connecting ring 113 to contract and tighten the connecting rod 21 along the movable notch 115 during the process of the locking ring 22 being screwed into the first connecting ring 112 or the second connecting ring 113 through threaded engagement.

[0039] Preferably, the axes of the first connecting ring 112 and the second connecting ring 113 on the same support base 11 are offset. In this case, the first connecting rings 112 of two adjacent support mechanisms 1 are facing each other, or the second connecting rings 113 of two adjacent support mechanisms 1 are facing each other. That is, the first connecting ring 112 of one support mechanism 1 faces the first connecting ring 112 of another support mechanism 1, and the second connecting ring 113 of one support mechanism 1 faces the second connecting ring 113 of another support mechanism 1. Because the axes of the first connecting ring 112 and the second connecting ring 113 on the same support base 11 are offset, the connecting rods 21 on opposite sides of the same support base 11 can be staggered. Compared with the method of multiple connecting rods 21 being coaxial, the stress positions can be staggered, the torsional strength can be improved, thereby avoiding the offset of the support mechanism 1 and ensuring that multiple support mechanisms 1 are arranged in a straight line.

[0040] Optionally, in other embodiments, the number of first connecting rings 112 and second connecting rings 113 on the same support base 11 can be different. For example, a first connecting ring 112 can be provided on one side of the support base 11, and two second connecting rings 113 can be provided on the other side of the support base 11; or two first connecting rings 112 can be provided on one side of the support base 11, and a second connecting ring 113 can be provided on the other side of the support base 11. The specific number of the first connecting rings 112 and the second connecting rings 113 can be adjusted according to requirements. With the above structure, the number of connecting rods 21 on opposite sides of the support base 11 can be different, which can also stagger the stress positions and improve the torsional strength.

[0041] Preferably, the connecting rod 21 is provided with a limiting groove (not shown in the figure, the same below) extending axially for a predetermined length. The locking ring 22 includes a limiting edge (not shown in the figure, the same below) placed in the limiting groove and used for sliding along the limiting groove. The limiting groove is used to limit the axial sliding stroke of the limiting edge. By cooperating with the limiting groove and the limiting edge, the position of the locking ring 22 is limited, the locking ring 22 is snapped and fixed on the connecting rod 21, and the locking ring 22 is allowed to move within a predetermined range. This facilitates the threaded engagement of the locking ring 22 with the first connecting ring 112 or the second connecting ring 113, while preventing the locking ring 22 from falling off the connecting rod 21, thereby avoiding the loss of parts at the construction site and making it more convenient to use.

[0042] It should be understood that in other embodiments, the connecting component 2 may also include only the connecting rod 21. The connection and fixation of two adjacent support seats 11 can be achieved by inserting the connecting rod 21 into the preset connecting hole on the support seat 11; or the connecting rod 21 can be fixed by fasteners such as clamps and top screws, which can also achieve the positioning and fixation of the connecting rod 21.

[0043] like Figure 2 As shown, the support mechanism 1 also includes a base 14 and a positioning component 15. The bottom end of the support seat 11 has a sleeve hole (not shown in the figure, the same below) adapted to the base 14. The support seat 11 is fitted onto the base 14 through the sleeve hole and is used for vertical movement along the base 14. The positioning component 15 is disposed between the support seat 11 and the base 14 and is used to lock and position the vertical movement of the support seat 11. Through the cooperation of the base 14 and the positioning component 15, the support seat 11 is supported and positioned. After the locking and positioning action of the positioning component 15 is released, the vertical movement of the support seat 11 can be realized. Therefore, the height of each support seat 11 can be flexibly adjusted according to the actual height of the construction site, so that the heights of multiple support seats 11 correspond.

[0044] Preferably, the base 14 has first pin holes 141 extending through opposite sides of the base 14 along a direction perpendicular to the mounting hole 111. Multiple first pin holes 141 are spaced apart along the height direction. The support base 11 has second pin holes 116 corresponding to the first pin holes 141 on opposite sides. The positioning component 15 includes positioning pins 151 that pass through the second pin holes 116 and the first pin holes 141 and extend outwards from opposite sides of the support base 11. That is, the positioning pins 151 penetrate the base 14 and the support base 11. While locking and positioning, the positioning pins 151 also strengthen the support of the support base 11, increasing its support strength.

[0045] Furthermore, multiple second pin holes 116 are spaced apart along the height direction of the support base 11, and multiple positioning pins 151 are provided. The multiple positioning pins 151 are used to be inserted into different second pin holes 116 and pass through the corresponding first pin holes 141. The multiple positioning pins 151 jointly support the support base 11, further improving the support strength and stability of the support base 11.

[0046] like Figure 1 As shown, the support mechanism 1 also includes a clamping component 16 disposed on the base 14. The clamping component 16 is used to clamp and fix the base 14 to a fixed structure on the construction site, such as clamping it to other steel bars. By clamping and fixing the base 14 with the clamping component 16, the base 14 can be prevented from shaking.

[0047] Furthermore, the clamping assembly 16 includes two clamping plates arranged opposite each other, and a compression spring disposed between the two clamping plates. The two clamping plates are hinged to each other at the middle position. The compression spring presses against the first end of the two clamping plates, thereby driving the second end of the two clamping plates to close elastically, realizing the clamping and fastening action.

[0048] like Figure 2 As shown, the opposite ends of the anti-slip sleeve 12 extend axially through the opposite ends of the mounting hole 111, and the clamping assembly 13 is fitted onto each opposite end of the anti-slip sleeve 12. By clamping the opposite ends of the anti-slip sleeve 12 with the two clamping assemblies 13, the reinforcing bars inside the anti-slip sleeve 12 can be strengthened, and the axial positioning of the anti-slip sleeve 12 can also be achieved, preventing the anti-slip sleeve 12 from moving axially relative to the mounting hole 111.

[0049] Furthermore, the clamp assembly 13 includes two clamp rings 131, each with a semi-circular ring structure. The first end of one clamp ring 131 is connected to the first end of the other clamp ring 131 by a screw 132; the second end of one clamp ring 131 is connected to the second end of the other clamp ring 131 by a screw 132, or the second end of one clamp ring 131 is hinged to the second end of the other clamp ring 131. The two clamp rings 131 together clamp the anti-slip sleeve 12, resulting in a simple and efficient locking structure.

[0050] Specifically, in this embodiment, both ends of the hoop 131 are connected to another hoop 131 by screws 132. In other embodiments, one end of the hoop 131 can be hinged to another hoop 131 so that the two hoop 131 can rotate and open and close relative to each other. The other ends of the two hoop 131 are connected by screws, which can also realize the tightening adjustment of the two hoop 131, making it more convenient to use.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
