Abstract
An antiskid indentation device for a concrete pavement. The utility model comprises indentation main rods, wherein the number of the indentation main rods is 2 or more than 2, and the indentation main rods are arranged in parallel; two ends of the indentation main rod are respectively and fixedly provided with 1 connecting rod, and the connecting rods and the indentation main rod are perpendicular to each other to form a rectangle; an operating handle is fixedly arranged on the connecting rod; two ends of the indentation main rod are tilted upwards, and form an included angle larger than 90 degrees with the horizontal main body part of the indentation main rod. The road surface anti-skid indentation depth and distance guaranteeing device has the advantages of being simple and practical in structure, convenient to manufacture, low in cost, capable of being repeatedly used, capable of effectively guaranteeing the depth and distance of pavement anti-skid indentations, guaranteeing safety of road traffic of steep slope construction and effectively improving construction efficiency.
Description
Technical Field
The utility model relates to an anti-skidding indentation device especially relates to a concrete road surface anti-skidding indentation device.
Background
In order to ensure the driving safety of vehicles on the construction sidewalk of the steep slope in the mountainous area, when a concrete pavement is laid, the surface layer needs to be treated by adopting anti-skid measures, and the traditional method is that workers carry out indentation treatment one by using long and thin wooden sticks or directly embed reinforcing steel bars on the surface layer as anti-skid measures. Because the construction pavement is long in inner distance and large in width, the worker can take time and labor to perform indentation by using a wooden stick one by one, the depth and line type of the indentation cannot be guaranteed, the antiskid requirement of a pavement surface layer is difficult to meet, and the attractiveness and the practicability are poor; the embedded steel bars greatly increase the material cost of construction and reduce the construction efficiency.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects that the existing steep slope construction pavement is treated by anti-skid measures, the anti-skid requirement of a pavement surface layer is difficult to meet, and the appearance and the practicability are poor; construction material cost increases, and the efficiency of construction reduces not enough, the utility model provides a concrete road surface antiskid indentation device.
The utility model provides a technical scheme that its technical problem adopted is: an antiskid indentation device for a concrete pavement comprises indentation main rods, wherein the number of the indentation main rods is 2 or more than 2, and the indentation main rods are arranged in parallel; two ends of the indentation main rod are respectively and fixedly provided with 1 connecting rod, and the connecting rods and the indentation main rod are perpendicular to each other to form a rectangle; an operating handle is fixedly arranged on the connecting rod.
Furthermore, two ends of the indentation main rod are tilted upwards, and form an included angle larger than 90 degrees with the horizontal main body part of the indentation main rod.
Further, the number of the indentation main rods is 3-5.
The indentation main rod comprises an indentation sleeve and an indentation rod, the indentation rod moves in the indentation sleeve, and the indentation rod and the indentation sleeve are axially fixed through a set screw.
The beneficial effects of the utility model are that, simple structure, practicality, the preparation is convenient, and is with low costs, can reuse, and the effectual degree of depth and the interval of guaranteeing road surface antiskid indentation guarantee the safety of abrupt slope construction pavement driving, effectively improve the efficiency of construction.
Drawings
Fig. 1 is a schematic structural diagram of the anti-skid indentation device for a concrete pavement of the utility model.
Fig. 2 is a schematic structural diagram of an embodiment of the present invention.
In the figure: 1. the pressing mark main rod, 2 connecting rods, 3 operating handles, 4 pressing mark sleeves, 5 pressing mark rods and 6 set screws.
Detailed Description
The present invention will be further explained with reference to the drawings and examples. However, it should be understood by those skilled in the art that the present invention is not limited to the specific embodiments listed, and should be included within the scope of the present invention as long as the spirit of the present invention is met.
See figure 1. The utility model relates to a concrete road surface antiskid indentation device, including indentation mobile jib 1, connecting rod 2, operating handle 3, the quantity of indentation mobile jib 1 is 2 or more than 2; preferably, the number of the indentation main rods 1 is 3-5. The plurality of indentation main rods 1 are arranged in parallel, two ends of each indentation main rod 1 are respectively and fixedly provided with a connecting rod 2, and the connecting rods 2 and the indentation main rods 1 are perpendicular to each other to form a rectangle; an operating handle 3 is fixedly arranged on the connecting rod 2.
Furthermore, two ends of the indentation main rod 1 tilt upwards, and form an included angle larger than 90 degrees with the horizontal main body part of the indentation main rod 1; preferably, the included angle is 130-135 degrees.
Referring to fig. 2, the indentation main rod 1 comprises an indentation sleeve 4 and an indentation rod 5, wherein the indentation rod 5 can move along an inner hole of the indentation sleeve 4, so that the length of the indentation main rod 1 of the indentation device can be adjusted and fixed according to the width of a construction access. A plurality of set screw holes are sequentially arranged along the axial direction of the indentation sleeve 4, and the indentation rod 5 and the indentation sleeve 4 are axially fixed by the set screws 6.
Preferably, the number of the indentation main rods 1 is 4, the 4 indentation main rods 1 are arranged at equal intervals, and the distance between every two adjacent indentation main rods 1 is 15-25 cm. 4 ends and connecting rod 2 fixed connection of 1 one end of 4 indentation mobile jib, 4 ends and another connecting rod fixed connection of the other end, indentation mobile jib 1 adopts welding mode fixed connection with connecting rod 2 usually. The operating handle 3 is fixedly connected with the connecting rod 2 through welding.
When the pavement surface layer is laid, 2 constructors respectively put the indentation device down in sequence along the pavement surface layer laying direction through the operating handle 3 at two ends of the indentation device and press traces. The indentation device can finish a plurality of indentations at one time, and the concrete does not have crack phenomenon after being reinforced, thereby ensuring the line type of the indentations and controlling the beauty and coordination of the pavement surface layer.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims.
