Abstract
The utility model discloses a height-adjustable scraping ruler, including the chi body, but height-adjusting's bolt is installed separately at the both ends of chi body, the chi body forms adjustable height with the construction road surface, works as the one end of chi body and corresponding bolted connection department with the other end of chi body and corresponding bolted connection department are not when same height, the chi body forms adjustable angle with the construction road surface. Set up the bolt through the both ends of chi body, make the situation that highly adaptation is different between chi body and the construction road surface through adjusting two bolts, the high control range is wide 0 ~ 50 mm. When the two bolts are at the same height, the ruler body is in a linear state and is suitable for a road surface without a slope; when two bolts are in not co-altitude, the chi body is the tilt state, is applicable to the road surface that has the slope, and adjustable slope (angle) scope is 0 ~ 1 degree.
Description
Technical Field
The utility model relates to a construction tool technical field specifically is a height-adjustable scraping ruler.
Background
A screed is a long ruler tool used to screed surfaces in plastering or cementing operations. At present, in the construction process of an expressway, asphalt is paved on the surface of the expressway to form an expressway asphalt pavement, after the asphalt pavement is finished, the asphalt surface is leveled by using a scraping rule, and because some road surfaces in the expressway have gradients and the heights of all the road surfaces are different, the scraping rule in the prior art cannot meet the requirements of the road surfaces with the gradients and the heights of the road surfaces.
Therefore, a scraping rule capable of meeting the requirements of the road surface with the gradient and the road surface with different heights is needed at present.
SUMMERY OF THE UTILITY MODEL
A primary object of the utility model is to provide a height-adjustable sliding rule solves among the prior art technical problem that the sliding rule can't satisfy the demand that has slope road surface and different road surface height.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a height-adjustable scraping ruler, includes the chi body, but the both ends of chi body are installed height-adjusting's bolt respectively, but the chi body forms adjustable height with the construction road surface, works as the one end of chi body and corresponding bolted connection department with the other end of chi body and corresponding bolted connection department are not when the same height, the chi body forms adjustable angle with the construction road surface.
Further optimize, the chi body is the aluminum alloy sliding rule. The scraping ruler made of the aluminum alloy material has good processability and high hardness, and can be used for uniformly troweling asphalt on the surface of a highway when the scraping ruler trowels the asphalt.
Further optimizing, the height of the bolt is 50-100 mm. The height of 50 ~ 100mm of bolt makes the distance adjustable setting 50 ~ 100mm between chi body and the construction road surface to adapt to the situation on the construction road surface of different pitch thickness.
Further preferably, the length of the ruler body is 3 m. The length of chi body has decided the application range of scraping the chi, and 3 m's length can be applicable to the construction road surface of the overwhelming majority.
Further optimizing, the adjustable angle is 0-1 degree. Because the highway slope on the highway is less, and the length of scraping chi is limited, so the adjustable angle of 0 ~ 1 degree is convenient for the scraping chi to adapt to the slope demand on road surface.
Further optimizing, the adjustable height is 0-100 mm. The adjustable height of 0-100 mm is adjusted according to the height of the bolt.
Further preferably, the bottom end of the bolt is provided with a ball head part or a chamfer part. In the scraping process, the ball head part or the chamfer part of the bottom wall of the bolt cannot damage the structure of the original road surface.
The utility model has the advantages that: 1. set up the bolt through the both ends of chi body, make the situation that highly adaptation is different between chi body and the construction road surface through adjusting two bolts, the high control range is wide 0 ~ 100 mm. 2. When the two bolts are at the same height, the ruler body is in a linear state and is suitable for a road surface without a slope; when two bolts are in not co-altitude, the chi body is the tilt state, is applicable to the road surface that has the slope, and adjustable slope (angle) scope is 0 ~ 1 degree. 3. The design of the ball head part or the chamfer part at the bottom end of the bolt ensures that the scraping ruler can not damage the pavement structure in the scraping process.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.
The embodiment 1 of the utility model is as shown in figures 1-3: the utility model provides a height-adjustable scraping ruler, includes chi body 1, but the both ends of chi body 1 are installed height-adjusting's bolt 2 respectively, chi body 1 forms adjustable height with the construction road surface, works as the one end of chi body 1 and corresponding bolt 2 junction with the other end of chi body 1 and corresponding bolt 2 junction are not when same height, chi body 1 forms adjustable angle with the construction road surface.
The ruler body 1 is an aluminum alloy scraping ruler.
The height of the bolt 2 is 50-100 mm.
The length of the ruler body 1 is 3 m.
The adjustable angle is 0-1 degree.
The adjustable height is 0-100 mm.
The bottom end of the bolt 2 is provided with a ball head part 3 or a chamfer part.
The utility model discloses a concrete operating procedure as follows: use when the user needs the utility model discloses when floating the pitch on the construction road surface, confirm the slope on construction road surface earlier, if construction road surface does not have the slope, adjust 2 bolts to same height at 1 both ends of chi body, according to the thickness of pitch again, the thickness that the distance adapted pitch between adjustment scale and the construction road surface, then will remove the utility model discloses make a round trip to remove repeatedly on the construction road surface to the pitch that will construct the road surface is floating.
When there is the slope on the road surface of being under construction, adjust 2 bolts to different heights at 1 both ends of chi body for the scope of adjustable slope (angle) is between 0 ~ 1 degree, again according to the thickness of pitch, adjusts the thickness that the distance adapts to pitch between scale and the road surface of being under construction, then will remove the utility model discloses make a round trip to move repeatedly on the road surface of being under construction to the pitch that will construct road surface is floating.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
