Further, the cambered surface bearing of trend of base plate and horizontal direction have angle theta, and 0 ° of < θ < 30 °.
Further, the arc diameter of the horizontal section of base plate is 50mm.
Further, base plate adopts 1.2mm stainless steel to make.
Further, the stock of L-type connecting rod is telescopic bar.
Further, handle is wood handle or rubber handle.
The one that the utility model provides smears arc perching knife, easily can complete internal corner part and smear arc process, no matter be can reach due effect from size or radian requirement, ensure applying ointment or plaster completely of waterproofing course and basic unit, can not occur that this position waterproofing course is piled up cracking, departed from the phenomenon of basic unit again, ensure waterproof construction quality.
Detailed description of the invention
Be clearly and completely described the technical solution of the utility model below in conjunction with accompanying drawing, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
The structure chart smearing arc perching knife that Fig. 1 provides for the utility model embodiment, as shown in Figure 1, the one that the utility model provides smears arc perching knife, comprises base plate 1, connecting rod 2 and handle 3, and base plate 1 is strip, and the horizontal section of base plate 1 is circular arc; Connecting rod 2 is L-type, and its one end is welded on the center of base plate 1 concave surface, and the other end is connected with handle 3, and the bearing of trend of handle 3 is consistent with the length direction of base plate 1.
As shown in Figure 2, bearing of trend and the horizontal direction of the cambered surface of base plate have angle theta, and 0 ° of < θ < 30 °, when θ is tending towards 0 °, base plate 1 tends towards stability, and is applicable to the internal corner part of process Rouno Cormer Pregrinding Wheel; When θ is tending towards 30 °, the radian of base plate 1 is gradually large, is applicable to the internal corner part of process compared with small round corner, and arc perching knife can be suitable for different large small round corner smears arc process, to meet the different radian size required for smearing of making like this.
Wherein, the material of base plate 1 adopts 1.2mm stainless steel, and stainless steel mass-energy prevents from getting rusty, and increases the service life; Certain base plate 1 can be also wooden or irony, only requires that bottom surface must be smooth; The material of handle 3 is wooden or rubber, and convenient construction personnel grasp, and the shape of handle 3 can have multiple, and the lateral cross section of such as handle 3 is circular or square, can also be polygon or semicircle; In addition, handle 3 and L-type connecting rod can be dismountablely be connected or be fixedly connected with, and such as one end of handle 3 is provided with hole, and passing hole is set in the quarter butt end of L-type connecting rod.
On the basis of above embodiment, the arc diameter D=50mm of the horizontal section of base plate 1; According to the requirement of waterproofing design and job specfication, the size of inner corner trim being smeared to arc carries out detailed understanding, namely inner corner trim require smear arc process transition right angle handing-over and arc diameter requirement is 50mm, therefore the perching knife of the arc diameter D=50mm of the horizontal section of a kind of base plate of special design, makes to smear arc size and radian all meets the requirements.Process inner corner trim is when smearing arc, and perching knife respectively launches 25mm in the plane of right angle and facade, and avoiding too high or widely affects next step construction (as decorations such as patch blocks) of waterproof.Because after construction of waterproof layer; the cement mortar rigid course of 20mm to 30mm is done on waterproofing course surface; and then carry out patch block or other decorations; after fish tail and waterproof layer is finished; the radian at this position is completely coating again to be covered; do not affect aesthetic property, final surface layer or the smooth vertical and horizontal right angle of the thin subsides of glue for tile or thick subsides the foot of a wall position inner corner trim.
On the basis of above embodiment, the stock of L-type connecting rod 2 is telescopic bar, and when not needing to use this perching knife, the telescopic direction of quarter butt along stock can be shunk, saving takes up room.Telescopic bar has multiple implementation, and such as expansion link comprises pipe and interior bar, and pipe is set on interior bar, and pipe is provided with multiple hole, and interior bar is provided with the elastic bumps coordinated with hole.
By above embodiment, the one that the utility model provides smears arc perching knife, be not suitable for the special of internal corner part for existing market to smear arc instrument, ad hoc meter is released, to plaster perching knife with arc, cement mortar can be carried out or arc construction smeared by waterproofing and leakage-stopping treasured, neither waste material, can increase work efficiency again, can also ensure that all inner corner trim radian sizes are unified.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
