Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment one, as shown in fig. 1 and 2.
A concrete structure object external corner arc forming structure comprises a body 1.
The body 1 is in a strip-shaped triangular prism shape, and an edge of one side surface of the body is an inwards-concave arc surface. Correspondingly, the longitudinal section of the body 1 is a right-angled isosceles triangle with the hypotenuse being an inward concave arc. The length of the body 1 is determined according to the size of a concrete structure. The radius of the arc surface is 40-100mm.
The arc surface is provided with a plurality of mounting holes I2 which penetrate through the body 1. The mounting hole I2 is perpendicular to the two right-angle sides of the triangle and is positioned at the middle point of the right-angle sides. The distance between the two mounting holes I2 on the same side is about 300mm.
The mounting hole I2 is a stepped hole, the big end faces inwards, the small end faces outwards and is matched with the round-head self-tapping screw, so that the round-head self-tapping screw can penetrate through the mounting hole I and then is connected with a pouring template of a concrete structure, and the body is fixed on the template. Meanwhile, the head of the round head self-tapping screw is embedded into the large end of the mounting hole I, so that the appearance of a forming surface is prevented from being influenced. Preferably, the round head self-tapping screw can be selected from M2.3 × 14.
The body 1 is fixed at an included angle of a pouring template of a concrete structure, and the arc surface faces the concrete structure, so that a fillet is directly formed at the corner of the concrete structure after demoulding.
The body can also be pasted on the template through materials such as double faced adhesive tape and the like, so that the construction is convenient.
The body can be made of solid plastics and other materials, and is easy to process and low in cost.
The embodiment is suitable for the condition that the external corner of the concrete structure is formed by the included angle of two templates, namely the vertical external corner. During the use, pack into this embodiment simultaneously when the template installation, adopt the screw to twist into both sides template at two right-angle faces and fix, embedding template degree of depth 1cm.
Example two, as shown in figures 3 and 4.
The structure of the present embodiment is substantially the same as that of the first embodiment, and the main difference is that the longitudinal section of the main body 1 of the present embodiment is a right trapezoid with an inward concave arc-shaped oblique side, and the oblique side of the main body is an equiangular triangle. A plurality of mounting holes II3 which penetrate through the body 1 are arranged between the upper bottom and the lower bottom of the trapezoid. The mounting hole II3 is also a stepped hole, the big end faces inwards, the small end faces outwards, and the mounting hole is perpendicular to the bottom edge of the trapezoid. The present embodiment is applicable to a case where the external corner of the concrete structure is formed by a single-sided form, i.e., a horizontal external corner. When the concrete side elevation control line is used, after the template is installed, the concrete side elevation control line is released from the side face of the template, marks are made, and the concrete side elevation control line is installed and screwed into the side template according to the elevation control line. Preferably, the bottom of the screw can be additionally provided with a gasket to increase the stress, so that the screw is prevented from damaging the body.
At present, a manual cutting and polishing mode is basically adopted when the external corner of a structure is processed in a construction site, so that the construction period is influenced, and manpower is wasted. The utility model discloses simple structure, convenient for material collection can be pre-buried contained angle department in the template before concrete structure pours to can directly form required fillet on concrete structure thing after the form removal, avoided pollution such as noise, dust that produce in the past at the external corner in-process of polishing, and reduced the manual work, shortened because of the time limit for a project of external corner cost of polishing, effectively improved efficiency of construction and quality.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
