Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular, to a tool for pressing in concrete pavement joints. Background Technology

[0002] In road construction, road surfaces need to be cut at regular intervals to accommodate the thermal expansion and contraction of the concrete. These cuts need to be filled with shrinkage material. For damaged existing cuts and expansion joints in older road surfaces, shrinkage material also needs to be filled after widening the joints. Currently, this is generally done manually, which not only consumes a lot of manpower and has low construction efficiency, but also results in incomplete and unsightly filling of the joints, failing to meet construction specifications and easily causing road surface bulges and poor driving comfort.

[0003] In response, Chinese utility model patent CN207812214U provides a roller-type concrete joint filler material pressing tool, which includes a roller, a rotating shaft, and a handle. The roller has an opening in the center, and the rotating shaft is bent to close the opening by passing through the center hole of the roller. Both ends of the rotating shaft are fixed to the handle. In use, the roller is pushed along the gaps in the concrete pavement by the handle, and the joint filler material can be pressed into the gaps using the roller. The structure is simple and the operation is convenient and quick, which can improve the pressing effect compared to manual pressing. However, since the gaps in the concrete pavement have a certain depth, if the roller goes too deep into the gap, the joint filler material will be pressed too deeply, and the upper layer of the gap will not be filled. If the roller only rolls along the upper layer of the gap, the lower layer of the gap will not be filled densely, which will not meet the construction specifications. Utility Model Content

[0004] This invention provides a concrete pavement joint filling tool to solve the technical problem that existing concrete pavement joint filling tools have poor filling effect and cannot ensure that the bottom and top layers of the concrete pavement joints are filled densely.

[0005] According to one aspect of the present invention, a concrete pavement joint filling tool is provided, comprising a support, a first roller and a second roller spaced apart on the support along the joint filling direction, the first roller including an extrusion plate for rolling along the joint of the concrete pavement and pressing the joint filler into the bottom layer of the joint, the second roller including a limiting wheel and a pressing protrusion ring disposed in the middle of the limiting wheel, the pressing protrusion ring being used to embed into the joint of the concrete pavement and compact the joint filler, the limiting wheel being used to roll against the upper surface of the concrete pavement and limit the pressing depth of the pressing protrusion ring.

[0006] Preferably, the bracket includes a support rod and a telescopic assembly. The telescopic assembly is connected to the middle of the support rod and its length is adjustable. The telescopic assembly is inclined downward in a direction away from the support rod. The first roller is rotatably disposed at the bottom end of the telescopic assembly, and the second roller is rotatably disposed at the bottom end of the support rod.

[0007] Preferably, the telescopic assembly includes a fixed tube, a telescopic tube, and a locking member. The fixed tube is fixed to the support rod, the telescopic tube is sleeved on the fixed tube and used for telescopic movement relative to the fixed tube, and the locking member is used to lock the telescopic tube relative to the fixed tube.

[0008] Preferably, the fixed tube has a plurality of positioning holes spaced apart along its length, and the telescopic tube has a locking hole. The telescopic tube is used to telescopically move relative to the fixed tube until the locking hole aligns with any one of the positioning holes. The locking member includes locking bolts that are sequentially inserted and fixed in the locking hole and the positioning hole.

[0009] Preferably, the support rod is a steel pipe, and the bracket further includes a grip handle horizontally disposed on the upper part of the support rod.

[0010] Preferably, the axial width of the pressing ring is adapted to the gap width of the concrete pavement.

[0011] Preferably, the axial width of the extrusion sheet is smaller than the axial width of the pressure ring.

[0012] Preferably, both ends of the pressing ring have chamfered structures.

[0013] Preferably, the concrete pavement joint filling tool further includes two mounting frames respectively mounted on the support, the mounting frames being equipped with bearings, and the first roller and the second roller being fitted onto the bearings of the two mounting frames in a one-to-one correspondence.

[0014] Preferably, the mounting bracket is provided with a scraper above the bearing, the scraper being used to scrape off the sealant adhering to the first roller or the second roller.

[0015] This utility model has the following beneficial effects:

[0016] 1. The concrete pavement joint filling tool provided by this utility model has a first roller and a second roller spaced apart along the filling direction. The first roller can extend into the bottom layer of the gap and compact the joint filler through the extrusion plate. The second roller precisely controls the compaction depth through the cooperation of the limiting wheel and the pressing convex ring, so that the pressing convex ring can roll and compact the material along the upper layer of the gap. In use, the first roller and the second roller are pushed by the bracket to roll along the gap of the concrete pavement in sequence. First, the joint filler is squeezed into the bottom layer of the gap by the first roller, and the excess joint filler is squeezed to the opposite sides of the extrusion plate. Then, the excess joint filler is compacted into the gap by the second roller, ensuring that the bottom layer and the upper layer of the gap can be filled densely, meeting the construction specifications. It can also precisely control the depth of the joint filler relative to the upper surface of the concrete pavement, avoiding excessive pressing and causing deep gaps in the pavement, and also avoiding the joint filler bulging and affecting driving comfort.

[0017] 2. The concrete pavement joint filling tool provided by this utility model includes a support rod and a telescopic component. The telescopic component is connected to the middle of the support rod and its length is adjustable. The telescopic component is inclined downwards in a direction away from the support rod. A first roller is rotatably mounted at the bottom end of the telescopic component, and a second roller is rotatably mounted at the bottom end of the support rod. By adjusting the length of the telescopic component, the first and second rollers can be aligned on the same horizontal line, while the tilt angle of the support rod can be adjusted, making it easier for operators of different heights to hold and use, thus improving ease of use. More importantly, by adjusting the tilt angle of the support rod, the center of gravity of the support can also be adjusted, thereby adjusting the downward pressure on the first and second rollers. This prevents the first roller from applying too much pressure, causing the extrusion plate to completely squeeze out the joint filler in the gap, and also prevents the first roller from applying too little pressure, thus failing to compact the joint filler and improving the compaction effect.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

Detailed Implementation

[0024] 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.

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.

[0026] Figure 1 and Figure 2 The present invention provides a concrete pavement joint filling tool for pressing joint filler into the gaps of concrete pavement. The tool has a simple and efficient overall structure, can be assembled from materials obtained on the construction site, and can ensure the compactness, integrity and aesthetics of the joint filling, meeting the requirements of construction specifications and eliminating the need for rework.

[0027] like Figure 1As shown, the concrete pavement joint filling tool 1000 includes a support 1, a first roller 2, and a second roller 3. The first roller 2 and the second roller 3 are spaced apart at the bottom of the support 1 along the joint filling direction, meaning that the rolling directions of the first roller 2 and the second roller 3 are in a straight line, so that the first roller 2 and the second roller 3 can roll sequentially along the joint. Specifically, the first roller 2 includes an extrusion plate 21 for rolling along the joint of the concrete pavement and pressing the joint filler into the bottom layer of the joint. The extrusion plate 21 is a circular thin sheet structure with a thickness less than the width of the joint, so that the extrusion plate 21 can penetrate deep into the interior of the joint.

[0028] Please combine Figure 2 The second roller 3 includes a limiting wheel 31 and a pressing protrusion 32 disposed on the middle part of the limiting wheel 31. The pressing protrusion 32 is used to embed into the gap of the concrete pavement and compact the joint filler. The limiting wheel 31 is used to roll against the upper surface of the concrete pavement and limit the pressing depth of the pressing protrusion 32.

[0029] In the concrete pavement joint filling tool 1000, a first roller 2 and a second roller 3 are spaced apart along the filling direction. The first roller 2 can extend into the bottom layer of the gap and compact the joint filler through the extrusion plate 21. The second roller 3 precisely controls the compaction depth through the cooperation of the limiting wheel 31 and the pressing ring 32, so that the pressing ring 32 can roll along the upper layer of the gap to compact the filler. In use, the bracket 1 pushes the first roller 2 and the second roller 3 to roll along the gap of the concrete pavement in sequence. First, the first roller 2 squeezes the joint filler into the bottom layer of the gap, and the excess joint filler is squeezed to the opposite sides of the extrusion plate 21. Then, the second roller 3 compacts the excess joint filler into the gap, ensuring that both the bottom and upper layers of the gap are filled densely, meeting the construction specifications. It can also precisely control the depth of the joint filler relative to the upper surface of the concrete pavement, avoiding excessive pressing that would cause deep gaps in the pavement, and also avoiding the joint filler bulging out and affecting driving comfort.

[0030] Furthermore, the axial width of the limiting wheel 31 is more than twice the axial width of the pressing ring 32, so that the limiting wheel 31 can fully conform to the upper surface of the concrete pavement and roll, thereby improving stability.

[0031] Furthermore, the axial width of the limiting wheel 31 on both sides of the pressing ring 32 is greater than the axial width of the pressing ring 32, which further improves stability and prevents the limiting wheel 31 from entering the gap of the concrete pavement.

[0032] Preferably, the support 1 includes a support rod 11 and a telescopic assembly 12. The telescopic assembly 12 is connected to the middle of the support rod 11 and its length is adjustable. The telescopic assembly 12 is inclined downwards in a direction away from the support rod 11. The first roller 2 is rotatably disposed at the bottom end of the telescopic assembly 12, and the second roller 3 is rotatably disposed at the bottom end of the support rod 11. By adjusting the length of the telescopic assembly 12, the first roller 2 and the second roller 3 are aligned on the same horizontal line, while the tilt angle of the support rod 11 can be adjusted, making it easier for operators of different heights to hold and use, thus improving ease of use.

[0033] More importantly, by adjusting the tilt angle of the support rod 11 through the telescopic component 12, the downward pressure on the first roller 2 and the second roller 3 can also be adjusted, so as to... Figure 1 Taking the direction shown as an example, when the upper part of the support rod 11 tilts to the left (i.e., the tilt angle increases in the direction away from the first roller 2), the center of gravity of the bracket 1 is closer to the second roller 3, and the downward pressure applied to the first roller 2 decreases. Conversely, when the tilt angle of the upper part of the support rod 11 in the direction away from the first roller 2 decreases, the center of gravity of the bracket 1 is closer to the first roller 2, and the downward pressure applied to the first roller 2 increases. Therefore, during use, the tilt angle of the support rod 11 can be adjusted according to the actual pressing state to adjust the pressing force of the first roller 2. This avoids excessive pressing force of the first roller 2, which would cause the extrusion plate 21 to completely squeeze out the sealant in the gap, and also avoids insufficient pressing force of the first roller 2, which would fail to compact the sealant, thus improving the pressing effect.

[0034] Furthermore, the telescopic assembly 12 includes a fixed tube 121, a telescopic tube 122, and a locking member (not shown in the figure, the same below). The fixed tube 121 is fixed to the support rod 11, the telescopic tube 122 is sleeved on the fixed tube 121 and used for telescopic movement relative to the fixed tube 121, and the locking member is used to lock the telescopic tube 122 relative to the fixed tube 121. The telescopic tube 122 and the fixed tube 121 can be made of ordinary steel pipes. The telescopic adjustment is achieved through the nesting cooperation of the telescopic tube 122 and the fixed tube 121, and the length adjustment structure is simple and efficient.

[0035] Furthermore, the fixed tube 121 has a plurality of positioning holes 1211 spaced apart along its length, and the telescopic tube 122 has a locking hole 1221. The telescopic tube 122 is used to telescopically move relative to the fixed tube 121 until the locking hole 1221 aligns with any one of the positioning holes 1211. The locking component includes locking bolts that are sequentially inserted and fixed in the locking hole 1221 and the positioning hole 1211. By sequentially inserting and fixing the locking bolts in the locking hole 1221 and the positioning hole 1211, the axial positioning of the telescopic tube 122 relative to the fixed tube 121 can be achieved, thereby locking and fixing the telescopic tube 122.

[0036] In other embodiments, the locking member may also include a hoop provided on the telescopic tube 122, and the telescopic tube 122 clamps the fixed tube 121 through the hoop, which can also achieve the locking and fixing of the telescopic tube 122 relative to the fixed tube 121.

[0037] Preferably, the support rod 11 is made of steel pipe, and the bracket 1 further includes a grip handle (not shown in the figure, the same below) horizontally disposed on the upper part of the support rod 11. Specifically, the grip handle can also be made of steel pipe, and the grip handle is vertically disposed relative to the support rod 11 and extends in the horizontal direction so that the operator can grip and use it. The grip handle can also be covered with a rubber sleeve, cloth sleeve or other anti-slip structure.

[0038] In one embodiment, the grip handle is located only on one side of the support rod 11. The operator can hold the support rod 11 with one hand to push and roll, and hold the grip handle with the other hand to control the rolling direction. In another embodiment, the grip handle can also be located on opposite sides of the support rod 11. In this case, the operator can hold the two grip handles with both hands respectively, push the concrete pavement joint filling tool 1000 to move as a whole to roll and fill the joints, and can also adjust the rolling direction in real time.

[0039] Preferably, the axial width of the pressing ring 32 is adapted to the gap width of the concrete pavement, that is, the axial width of the pressing ring 32 is equal to the gap width of the concrete pavement, or the axial width of the pressing ring 32 is 0.1-1mm smaller than the gap width of the concrete pavement, so that the pressing ring 32 can fully compact the joint filler in the gap and ensure the filling effect.

[0040] Preferably, the axial width of the extrusion piece 21 is smaller than the axial width of the pressing ring 32, so that the extrusion piece 21 can be inserted into the bottom layer of the concrete pavement gap without interference, further improving the filling effect.

[0041] Preferably, both ends of the pressing ring 32 are provided with chamfered structures 321. While the pressing ring 32 is rolling and filling the joint, the chamfered structures 321 can make the joint filler form a chamfer between the joint filler and the side wall of the concrete pavement joint, so that the joint filler can fully adhere to the joint of the concrete pavement, improve the adhesion and tightness of the joint filler, and improve the sealing effect.

[0042] Preferably, the concrete pavement joint filling tool 1000 further includes two mounting frames 4 respectively disposed on the bracket 1. Each mounting frame 4 is equipped with a bearing 41, and the first roller 2 and the second roller 3 are correspondingly fitted onto the bearings 41 of the two mounting frames 4. That is, the mounting frames 4 are provided at the bottom end of both the telescopic component 12 and the bottom end of the support rod 11. The first roller 2 is mounted on the bearing 41 of the mounting frame 4 at the bottom end of the telescopic component 12, and the second roller 3 is mounted on the bearing 41 of the mounting frame 4 at the bottom end of the support rod 11. Both the first roller 2 and the second roller 3 are fixed in place by the bearings 41, which improves the smoothness of rotation of the first roller 2 and the second roller 3 and prevents jamming.

[0043] Preferably, the mounting bracket 4 is provided with a scraper 42 above the bearing 41. The scraper 42 is used to scrape off the sealant adhering to the first roller 2 or the second roller 3, so as to avoid the sealant adhering and fixing to the first roller 2 or the second roller 3 and affecting the subsequent sealant pressing effect.

[0044] Specifically, the mounting frame 4 includes two legs respectively disposed on the axial ends of the bearing 41, and a crossbeam horizontally disposed above the bearing 41 and connecting the two legs into a whole. The crossbeam and the two legs together form a gantry structure with high structural strength and will not interfere with the filling and pressing operation of the first roller 2 and the second roller 3.

[0045] Furthermore, the scraper 42 is made of flexible materials such as rubber and silicone, and the scraper 42 is detachably connected to the crossbeam so as to disassemble and replace the scraper 42 and facilitate cleaning and maintenance of the scraper 42.

[0046] 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.
