For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 3 As shown, the embodiment of the utility model discloses a cement concrete road reinforcement rod quick installation device. The device comprises a hard rod 1, on which a plurality of pressure columns 2 are arranged at equal intervals, the pressure columns 2 are perpendicular to the hard rod 1, and the pressure columns 2 are parallel to each other.

[0027] The arrangement spacing of these lower pressure columns 2 is equal to the required cutting distance of the steel bar tie rod 5, the length of the lower pressure column 2 is equal to the required installation depth of the steel bar tie rod 5, and a positioning device 3 is provided at the lower end of the lower pressure column 2, and the positioning device 3 positions the steel bar tie rod 5. A handle 4 is provided at each end of the hard rod 1.

[0028] See also Figure 3 The quick installation device can press the steel bar tie rod 5 into cement concrete. When the hard rod 1 is pressed down, the lower pressure column 2 applies pressure to the steel bar tie rod 5 and presses the steel bar tie rod into cement concrete.

[0029] In one embodiment, the hard rod 1 and the pressure column 2 are both steel pipes. The hard rod 1 can also be made of other materials such as a wooden rod. When a steel pipe is used, the hard rod 1 and the pressure column 2 can be made of a steel pipe with a diameter of 50 mm. That is, the diameters of the hard rod 1 and the pressure column 2 are both 50 mm. In this embodiment, the hard rod 1 can be made of a whole steel pipe, but in other embodiments, the hard rod 1 can also be made of two steel pipes spliced ​​together. When splicing, flanges are welded at the ends of the two steel pipes, and the two flanges are fixed together by bolts to achieve the purpose of connecting to a complete hard rod. Alternatively, a wooden stick or steel pipe is set as an intermediate connecting piece, and the two ends of the intermediate connecting piece are respectively inserted into the ends of the two steel pipes. The diameter of the wooden stick or steel pipe is roughly equal to the inner diameter of the hard rod 1, and the two steel pipes can also be connected to form a complete hard rod. When the hard rod is spliced, it can be disassembled and shortened in length, so that it can be placed in the truck bed of a vehicle, and can be transported using a small vehicle, which improves the flexibility during transfer.

[0030] In one embodiment, the lower pressure column 2 is welded to the hard rod 1. When the lower pressure column 2 is welded to the hard rod 1, the connection is reliable and compact. In addition, the lower pressure column 2 can also be fixed to the hard rod 1 by a connecting member such as a bolt. The lower pressure column 2 can also be made of materials such as an aluminum tube to reduce weight and make it more convenient for operators to operate.

[0031] In one embodiment, the arrangement spacing of the pressure column 2 is 90cm and the length is 10cm. That is to say, the required installation depth of the steel bar pull rod 5 pressed into the cement concrete is 10cm, and the required spacing for blanking is 90cm. The arrangement spacing refers to the distance between two adjacent pressure columns 2. When measuring, it can be the closest distance between the outer walls of the two pressure columns 2, or it can be the distance between the center lines of the two pressure columns 2. The difference in the measured values ​​of the two can be regarded as an acceptable error range, because the positioning accuracy requirements of the pressure column 2 are not high. According to different requirements, the arrangement spacing of the pressure column 2 can be set to different values.

[0032] In one embodiment, the positioning device 3 is two steel columns welded to the lower end of the lower pressure column 2. The length of the steel column is 3 cm and the diameter is 14 mm. The number of the lower pressure columns 2 is 6.

[0033] like Figure 3As shown, when in use, two operators lift the hard rod 1 by the handles 4 at both ends of the hard rod 1, place the quick installation device on the center line of the road, and place a steel bar 5 at the positioning device 3 under each down-pressure column 2, that is, place the steel bar 5 between the two steel columns, and make the steel bar 5 roughly vertical to the hard rod 1, and the center point of the steel bar 5 is located at the center of the lower end of the down-pressure column 2. Then, press the hard rod 1 downward with force, the lower end of the down-pressure column 2 contacts the steel bar 5 and transmits pressure to the steel bar 5, and these steel bar 5 enter the cement concrete that has just been laid on the ground and has not yet hardened and is still in a flowing state under pressure. Then, lift the hard rod 1 upward, and the steel bar 5 remains in the cement concrete. The cement concrete road steel bar quick installation device can quickly locate the position of the steel bar 5 at one time, and quickly press these steel bar 5 into the cement concrete at one time, which is efficient, easy to operate, and improves the construction speed.

[0034] Compared with the traditional construction method, the present application can change the 6m wide concrete road from the original process of half-casting, first casting half, waiting for the cement concrete to solidify before removing the formwork and continuing to cast the other half, to the current one-time casting, thereby improving the efficiency of steel bar installation and providing a guarantee for the completion of the project on schedule. The application of the steel bar fast installation device shortens the construction period, improves the template turnover rate, reduces the investment in labor costs, and improves the economic benefits of the project.

[0035] The following is the test data on the test section.

[0036] A 270-meter concrete pavement of a certain road project was used as a test section. When the quick installation device was used for construction, the center line of the pavement was imported into the GPS in advance. One person stood at the longitudinal joint of the pavement and measured the center line position with the GPS, one person held one end of the tool, one person held the other end, and one person held a ruler to place the steel bar tie rod. After the steel bar tie rod was placed, it was pressed into the concrete, which was one round.

[0037] According to on-site statistics, it takes 20 seconds to find the center line, 10 seconds for 2 people to ensure the horizontal position, and 15 seconds for 1 person to place 6 steel bars and press them into the concrete. A total of 45 seconds

[0038] 301 steel rods need to be placed 51 times, 45 seconds each time, which means 38.25 minutes, with a rest time of 5 minutes, for a total of 43 minutes.

[0039] When using manual installation of a single steel bar, import the center line of the pavement into the GPS in advance. One person stands at the longitudinal joint of the pavement, holding the GPS to measure the center point and one end of the tool. Two people are needed to pull the line horizontally, and another person needs to hold the other end of the tool vertically to ensure that it is perpendicular to the longitudinal joint and start placing the steel bars with the tool and pressing them into the concrete. This is one round.

[0040] It takes 15 seconds to find the center line, 2 people pull the line horizontally for 10 seconds, and 1 person places a steel bar and presses it into the concrete for 5 seconds, for a total of 30 seconds. 301 steel bars need to be placed, 301 times, 30 seconds each time, which takes 150.5 minutes, and a rest time of 10 minutes, for a total of 160.5 minutes.

[0041] In summary, on the 270m test section, the use of this quick installation device saved 117.5 minutes and greatly improved the efficiency of steel bar tie rod installation.
