Abstract
The utility model discloses a cement-concrete road-surface groove-carving device, which comprises a crossbeam, carving teeth, an operating rod and a handheld frame, wherein the carving teeth are inlaid on the lower surface of the crossbeam, the lower end of each carving tooth is arc-shaped, the carving teeth are made of an elastic material, the operating rod is fixed on the rear surface of the crossbeam, and the handheld frame is fixed on the upper surface of the crossbeam. The cement-concrete road-surface groove-carving device has the beneficial effects that: the cement-concrete road-surface groove-carving device has a simple structure and is convenient to operate, so that uniform and consistent carving grooves are formed on a cement-concrete road surface, the standard requirements of relevant specifications on the friction coefficient of the cement-concrete road surface can be completely met, and the damage to the cement-concrete road surface can not be caused in construction; and the cement-concrete road-surface groove-carving device is economical and practical and has low manufacturing cost, the engineering cost can not be greatly increased, and the cement-concrete road-surface groove-carving device is more economical.
Description
Technical field
The utility model relates to a kind of cutting device, particularly a kind of cement concrete pavement cutting device.
Background technology
At present, in construction of cement concrete road surface, in order to reach the technical standard requirement of the relevant surface friction coefficient of related specifications, need form the cutting of pitted skin or formation certain specification on the surface of cement concrete pavement, will reach the friction factor technical standard on road surface like this, the pitted skin on road surface or cutting adopt two kinds of methods to construct in cement concrete pavement construction at present, a kind of is after cement concrete pavement has flattened, before having to form, intensity do not form pitted skin or cutting on the surface on concrete road surface with hairbrush or steel brush, also having a kind of way is after the intensity on concrete road surface forms, use special cutting machinery to form cutting and be called for short " hard cutting " on the surface on road surface, when a kind of method is constructed before adopting, the pitted skin that uses hairbrush to form on the concrete surface, friction factor does not often reach code requirement, be unfavorable for the safety of driving a vehicle, do not reach the acceptance criteria on road surface yet, as when using steel brush to form cutting, work progress brush tooth is easy to the rubble in the concrete or the grains of sand are ticked, make local produce more serious hole groove and pitted skin, the position that forms hole groove and pitted skin after the road surface is open to traffic will be damaged in the short time, must keep in repair.When adopting second method to carry out " hard cutting " construction, because the replacing of the saw blade of gaining machine is frequent, cause construction costs to increase substantially, the engineering cost increasing degree is bigger, and is uneconomical.
Summary of the invention
The purpose of this utility model is not reach requirements in order to solve in cement concrete pavement construction the pitted skin that uses hairbrush to form on the concrete surface, damage concrete surface and " cutting firmly " the high problem of cost when using the steel brush cutting easily and the cement concrete pavement cutting device that provides.
The utility model by crossbeam, carve tooth, action bars and hand-held frame and form, wherein carve tooth be embedded in crossbeam below, the lower end of carving tooth is an arc, quarter, tooth was made by elastomeric material, action bars is fixed on the back of crossbeam, hand-held frame be fixed on crossbeam above.
Operating principle of the present utility model:
The utility model is after the concrete evenness of road surface is intact, the intensity on surface is not used before forming, need two people's compounding practices, at first carrying hand-held frame by the cutting device being put on the surface of road surface one side across the service bridge on the cement concrete pavement by a people, the tooth at quarter that is embedded in the crossbeam lower end is contacted with the road surface, another person draws the opposite side of cutting device to the road surface by the action bars that is fixed on the crossbeam, make and carve tooth and on the road surface, form uniform cutting, because carving the tooth lower end is arc, and be to make by elastomeric material, guaranteed the cutting uniformity on the road surface, when carving tooth and run into the rubble in the concrete and the grains of sand, carving tooth will be upspring, and carves the surface that tooth can road pavement and causes damage.
The beneficial effects of the utility model are:
1, simple in structure, easy to operate, make cement concrete pavement form the cutting of uniformity, can reach the standard-required of relevant specification fully, and in construction, can not cause damage cement concrete pavement to the cement concrete pavement friction factor;
2, economical and practical, cost of manufacture is cheap, can not increase considerably engineering cost, and is both economical.
Description of drawings
Fig. 1 is the utility model schematic perspective view.
1, crossbeam 2, carve tooth 3, action bars 4, hand-held frame.
The specific embodiment
See also shown in Figure 1: the utility model by crossbeam 1, carve tooth 2, action bars 3 and hand-held frame 4 and form, wherein carve tooth 2 be embedded in crossbeam 1 below, the lower end of carving tooth 2 is an arc, carving tooth 2 is made by elastomeric material, action bars 3 is fixed on the back of crossbeam 1, hand-held frame 4 be fixed on crossbeam 1 above.
Claims (2)
1. cement concrete pavement cutting device, it is characterized in that: by crossbeam, carve tooth, action bars and hand-held frame and forms, wherein carve tooth be embedded in crossbeam below, quarter, the lower end of tooth was an arc, action bars is fixed on the back of crossbeam, hand-held frame be fixed on crossbeam above.
2. cement concrete pavement cutting device according to claim 1 is characterized in that: described quarter, tooth was made by elastomeric material.
