Description
Technical field
The utility model relates to a kind of instrument drawing angle for negative and positive angle, belongs to the realm of building construction.
Background technology
Classification of waterproof is divided into level Four according to water protection standards by underground construction, and setting up defences according to underground project waterproof requires to select one to two kinds of waterproof measures.In current design, the waterproof measure that agent structure is often selected is waterproof concrete+waterproof roll or waterproof concrete+water-repellent paint.
In " Technical code for water proof in underground engineering " (GB50108), coil waterproof layer 4.3.7 article requires that circular arc or 45 ° of slope angles should be made by negative and positive angle place, and coating waterproof layer 4.4.10 article, 4.7.5 article, bentonite waterproof material waterproofing layer all require that in the arc-shaped or slope angle should be done in basic unit's negative and positive angle.In " underground waterproof engineering inspection of quality specification " (GB50208), coil waterproof layer 4.3.5 article requires that circular arc or 45 ° of slope angles should be made in basic unit's negative and positive angle, and coating waterproof layer 4.4.4 article, 4.7.3 article, bentonite waterproof material waterproofing layer all require that circular arc or slope angle should be made in basic unit's negative and positive angle.
Ductility and the toughness of coiled material have the limit, at negative and positive angle 90 ° hard curved, coiled material easily ftractures or fractures, and the paving of circular arc or slope angle also can ensure the paving quality of coiled material, can not produce the phenomenon of hollowing or ponding.Coating is smeared square position is also bad, is not easy painting and puts in place, can cause in uneven thickness, affect waterproof effect.The construction that circular arc or slope angle are conducive to waterproofing course is made at negative and positive angle, ensures construction of waterproof layer quality.
In the past in site operation, less demanding to basic unit's negative and positive angle, often can't carry out specially treated to negative and positive angle in construction.Along with building operations regulation and standardization, become more meticulous, many building sites require more and more higher to the based process of waterproofing course, unit in charge of construction also starts to pay attention to the process at negative and positive angle, but the operant level of workman is limited, claying knife is adopted arbitrarily to strike off, angle differs, and the negative and positive angle planeness after construction is poor, and impression quality is poor.Pvc pipe is cut half by some employings, carries out drawing angle, inconvenient operation with the pvc pipe of semicircle.
Utility model content
The technical problems to be solved in the utility model, provides a kind of instrument drawing angle for negative and positive angle, changes the shape of original claying knife, be processed into circular arc, and increase and be flexibly connected, while circular arc is made at the negative and positive angle meeting code requirement, simple operations again, convenient construction uses.
The utility model is realized by following proposal: a kind of instrument drawing angle for negative and positive angle, it mainly comprises woodenly smears tool plate and wooden handle, described wooden tool plate of smearing is by arc plate, left tiltedly straight plate and the right side tiltedly straight plate composition, one end of described arc plate is linked on a described left side tiltedly oblique straight plate of straight plate and the described right side respectively, form integral structure, described arc plate is provided with 2 handles connecting holes: left handle connecting hole and right handle connecting hole, described wooden handle is made up of cross handle and perpendicular handle, described cross handle is flexibly connected with described left handle connecting hole, described perpendicular handle is flexibly connected with described right handle connecting hole, described cross handle is movably attached to described left handle connecting hole from the back side inner corner trim of described arc plate, form inner corner trim when described perpendicular handle is movably attached to described right handle connecting hole from the back side inner corner trim of described arc plate and smear tool, described cross handle is movably attached to described left handle connecting hole from the front external corner of described arc plate, male trowel tool is formed when described perpendicular handle is movably attached to described right handle connecting hole from the front external corner of described arc plate.
Described left handle connecting hole and described right handle connecting hole are in the same horizontal line.
Described cross handle and described perpendicular handle orthogonal, and the length of described cross handle is longer than described perpendicular handle.
The beneficial effects of the utility model are:
1, the utility model is a kind of draws the instrument at angle to adopt for negative and positive angle woodenly to smear tool, change the shape of original claying knife, be processed into circular shape, handle connecting hole is all provided with on wooden tool plate two sides of smearing, handle can be flexibly connected with the handle connecting hole smearing any one side of tool plate, smears tool respectively as male trowel tool and inner corner trim;
2, the utility model is a kind of draws the tool construction at angle simple for negative and positive angle, and convenient construction uses, and turn improves efficiency of construction, reduces labour intensity, accelerating construction progress.
