Abstract
Description
Technical Field
[0001] The utility model belongs to the field of road construction, and particularly relates to a wet cutting seam device for road concrete. Background Art
[0002] In order to avoid the disadvantages of the traditional cutting seam process for concrete pavement, such as high noise and high cost, the wet cutting seam process is mostly adopted for concrete roads at present. After the concrete reaches a certain strength, workers use a wet cutting seam machine to cut seams, and a seam is cut every 3-4 m along the width direction of the road. When using the wet cutting seam machine to cut seams, workers need to place a square wooden block on one side of the wet cutting seam machine to ensure the straightness of the cutting seam. This method cannot completely limit the wet cutting seam machine, and there is still a deviation space on the other side of the wet cutting seam machine, making it difficult to ensure the straightness. In addition, during construction, it is necessary to continuously measure with a ruler to determine the position of the next cutting seam, and the process is cumbersome and discontinuous. Sometimes, if there are measurement errors on both sides of the road, it will also cause the cutting seams to be skewed and not parallel to each other. Summary of the Invention
[0003] The problem to be solved by the present invention is to overcome the deficiencies of the background art and provide a wet cutting seam device for road concrete.
[0004] The present invention is achieved by the following technical solutions:

The wet cutting seam machine includes a cutting seam plate, a cutting seam knife is fixedly arranged in the middle of the bottom surface of the cutting seam plate. An expansion rod is hinged upward on the upper surface of the cutting seam plate, and a fixing nut is arranged at the hinged position. Baffles are vertically arranged upward on the periphery of the cutting seam plate except for the edge close to the expansion rod side. The device also includes two parallel limiting strip blocks. The length of the limiting strip blocks is greater than the width of the road. Screws are fixedly arranged at both ends of the limiting strip blocks. Adjusting strip blocks are arranged on both sides of the limiting strip blocks. Horizontal adjusting holes are arranged on the adjusting strip blocks. The screws pass through the adjusting holes, and the screws can slide left and right along the adjusting holes. The limiting strip blocks and the adjusting strip blocks are fixed together by fastening nuts on the screws. The device also includes a number of L-shaped plates symmetrically arranged along the length direction of the road on both sides of the road. The adjusting strip blocks can slide along the L-shaped plates when placed on the L-shaped plates.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.
[0017] This embodiment includes a wet cutting seam device commonly used by workers. The wet cutting seam device includes a cutting seam plate 1, and a cutting seam knife 2 is fixedly installed downward in the middle of the bottom surface of the cutting seam plate 1. These are all conventional structures of existing wet cutting seam devices and will not be elaborated here. In this embodiment, a telescopic rod 3 is hinged upward on the upper surface of the cutting seam plate 1. The cutting seam plate 1 and the telescopic rod 3 are hinged through a fixed shaft. The bottom end of the telescopic rod 3 can rotate around the fixed shaft to adjust the inclination angle of the telescopic rod 3. A fixing nut 4 is provided on the fixed shaft at the hinge joint. By tightening the fixing nut 4, the telescopic rod 3 is fixed to keep its inclination angle. A baffle 5 is integrally provided vertically upward on the periphery of the cutting seam plate 1 except for the edge near the telescopic rod 3.
[0018] The device of this embodiment further includes two parallel limiting bar blocks 6. Square timbers commonly used on construction sites are selected as the limiting bar blocks 6. The length of the limiting bar blocks 6 is greater than the width of the road, and the limiting bar blocks 6 are placed parallel to the road width direction. Screws 7 are fixed outward at both ends of the limiting bar blocks 6. Adjusting bar blocks 8 are provided on both sides of the limiting bar blocks 6. Short square timbers can also be selected as the adjusting bar blocks 8. Horizontal adjusting holes 9 are provided on the adjusting bar blocks 8. The screws 7 of the limiting bar blocks 6 pass through the adjusting holes 9, and the screws 7 can slide left and right along the adjusting holes 9. The distance between the two limiting bar blocks 6 is adjusted through the screws 7. The distance between the two limiting bar blocks 6 is determined according to the width of the wet cutting saw. Threaded fastening nuts 10 are connected to the screws 7, and the limiting bar blocks 6 and the adjusting bar blocks 8 are fixed together through the fastening nuts 10 on the screws 7.
[0019] This embodiment further includes several L-shaped plates 11 on both sides of the road. The L-shaped plates 11 are symmetrically arranged along the road length direction. One L-shaped plate 11 is drawn on each side in the attached drawing. The adjusting bar blocks 8 on both sides are respectively placed on the L-shaped plates 11 and can slide back and forth along the L-shaped plates 11. Among them, the height of the vertical plate 12 of the L-shaped plate 11 is lower than the height of the screw 7, so that the L-shaped plate 11 does not interfere with the adjustment of the limiting bar blocks 6. Scales are provided on the vertical plate 12. The spacing of the cutting seams is determined according to the scales on the vertical plate 12, eliminating the frequent measurement process.
[0020] In this embodiment, the above-mentioned L-shaped plates 11 can be made of L-shaped steel commonly seen on construction sites. To further ensure the stability of the L-shaped plates 11, screw holes are preferably provided at both ends of the L-shaped plates 11, and screws 13 are driven into the screw holes to fix the L-shaped plates 11 on the ground.
[0021] During construction, after the concrete reaches a certain strength, first adjust the distance between the two limiting bar blocks 6 according to the width of the wet cutting saw used, so that the outer sides of the two opposite baffles 5 of the wet cutting saw just stick to the inner sides of the two limiting bar blocks 6, making the wet cutting saw clamped between the two limiting bar blocks 6 and only able to slide between the two limiting bar blocks 6. After adjustment, tighten the fastening nuts 10 to fix the limiting bar blocks 6 and the adjusting bar blocks 8 together. Then, arrange the L-shaped plates 11 on the ground on both sides of the road according to the distance between the adjusting bar blocks 8 on both sides, so that the inner side of the vertical plate 12 of the L-shaped plate 11 can touch the adjusting bar block 8. Drive the screws 13 into the ground to fix the L-shaped plates 11. Determine the number of fixed L-shaped plates 11 according to the situation. Then place the wet cutting saw between the two limiting bar blocks 6, adjust the length and inclination of the telescopic rod 3, and fix the telescopic rod 3 through the fixing nut 4. Then one worker gently holds the limiting bar block 6 or the adjusting bar block 8, and another worker pushes the wet cutting saw between the two limiting bar blocks 6. After cutting, according to the scale on the vertical plate 12 of the L-shaped plate 11, hold the screw 7 and slide the device along the L-shaped plate 11 to the next cutting position to perform the next cutting seam.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
