Description
Technical field
It the utility model is related to a kind of grey knife for smearing arc chord angle.
Background technology
According to JGJ39-2016《Nursery, kindergarten's code of building design》Regulation, the corner of kindergarten and window erect
Fillet should be made at the external corners such as side.Workmen once encountered Equipment Foundations, air channel during kindergarten's engineering of constructing
The external corner part that a large amount of childs such as basis, step, corner, window can contact.It is all spatula that external corner part, which is plastered usually used,
Chi etc. is hung, causes efficiency of construction relatively low due to lacking special instrument, while existing instrument easily causes and is not easy to smear out rule
Fillet, fillet size of plastering are whard to control to influence the problem of attractive in appearance.
Utility model content
The purpose of this utility model be to provide it is a kind of smear fillet ash knife for kindergarten's engineering, to solve existing male trowel
Ash, which lacks specific purpose tool, causes efficiency of construction is relatively low, is not easy to smear out rule fillet, fillet size of plastering to be difficult to control influence U.S.
The technical problem of sight.
To achieve the above object, the utility model adopts the following technical scheme that：
It is a kind of to smear fillet ash knife for kindergarten's engineering including horizontal one section of operation holding rod, parallel with operating holding rod
One section of face smears circular arc knife bar and attended operation holding rod and smears the connecting rod between fillet knife bar,
The length of the operation holding rod is more than the length for smearing fillet knife bar, and the fillet knife bar of smearing is cut by one section of pipe
Forming, the section of jurisdiction that cross section is fan ring, the central angle corresponding to the section of jurisdiction is 90 degree, big cambered surface of the section of jurisdiction including inner side,
The small cambered surface in outside and side, the big cambered surface are fixedly connected with the connecting rod, and the small cambered surface is to smear fillet forming surface, described
Side is the blade of grey knife.
The connecting rod sets twice, is connected to operation holding rod and smears two ends of fillet knife bar, connecting rod altogether
Spacing be 15-20mm, connecting rod and the termination distance of operation holding rod are 20mm-40mm.
The connecting rod, operate holding rod and smear fillet knife bar and be in same plane, and connecting rod and operation holding rod
And smear vertical between fillet knife bar.
The connecting rod and operate holding rod and smear and be welded to connect between fillet knife bar.
The operation holding rod is not less than 40mm by diameter, and steel pipe of the wall thickness not less than 3mm is made.
The fillet knife bar of smearing is not less than 20mm by diameter, and steel pipe of the wall thickness not less than 2mm is cut into.
The connecting rod is made up of round steel of the diameter not less than 8mm.
The utility model has the characteristics that and beneficial effect compared with prior art：
The utility model using the material such as the existing round steel in building site and steel pipe, made it is a kind of smear the special grey knife of fillet,
The critical component of grey knife smears fillet knife bar using the pipe section of jurisdiction directly cut, and the central angle of the section of jurisdiction remains 90 degree,
The side of section of jurisdiction is blade, and the small cambered surface of section of jurisdiction is to smear fillet forming surface, it is ensured that all smooth smooth-goings of fillet, perception
Well, the size for smearing fillet is unified.The fillet size of plastering of the grey knife is controllable simultaneously, as long as replacing various sizes of section of jurisdiction
Smear out different size of fillet.The utility model can increase substantially the efficiency of construction plastered, have to smear external corner specific purpose tool
There is good economic benefit.
Brief description of the drawings
The utility model is described in more detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 side structure schematic view.
Fig. 3 is use state figure of the present utility model.
Reference：1- operations holding rod, 2- smear fillet knife bar, 3- connecting rods, 4- central angles, the big cambered surfaces of 21-,

Embodiment
Embodiment is a kind of to smear fillet ash knife, including horizontal one section of operation for kindergarten's engineering referring to shown in Fig. 1-3
Holding rod 1, with operating one section of 1 parallel face of holding rod smear circular arc knife bar 2 and attended operation holding rod 1 and smear between fillet knife bar 2
Connecting rod 3.
The length of the operation holding rod 1 is more than the length for smearing fillet knife bar 2, and the fillet knife bar 2 of smearing is by one section of pipe
Cutting forms, cross section is the section of jurisdiction of fan ring, and the central angle 4 corresponding to the section of jurisdiction is 90 degree, and the section of jurisdiction includes the big of inner side
Cambered surface 21, the small cambered surface 22 in outside and side 23, the big cambered surface 21 are fixedly connected with connecting rod 3, and the small cambered surface 22 is
