Abstract

The utility model discloses a plastic steel hollow porous internal corner template, belongs to a section bar for manufacturing a cast-in-place concrete mould, and aims to provide an internal corner template which is light in mass, low in cost and capable of being vertically used. The internal corner template comprises a right-angle-shaped body. The body (1) is of a hollow structure. A plurality of bearing ribs (2) which divide a cavity of the body into a plurality of pore cavities (3) are arranged in the cavity of the body. The pore cavity (3) located in the corner of the body is of a trapezoid or semicircular structure. The two right angle edges of the body (1) are respectively provided with a reinforcing rib (6) which stretches towards the right angle inner side. Connecting protruding blocks (5) are arranged on the inner sides of the reinforcing ribs (6). The plastic steel hollow porous internal corner template is simple in structure, high in hardness, not prone to deforming or cracking, light in mass and convenient to demount, has acid-alkali corrosion resistance and the anti-moth and antiflaming functions, and is a novel section bar which can replace a wooden internal corner template or a bamboo glue internal corner template or a steel internal corner template.

Description

Plastic-steel hollow porous internal corner formwork

Technical field

The utility model relates to the construction formwork that a kind of cast-in-situ concrete is used, and relates in particular to a kind of internal corner formwork for cast-in-situ concrete.

Background technology

Internal corner formwork is a kind of section bar of making cast-in-situ concrete mould, and the quality of its quality directly affects the quality of engineering construction.At present, widely used internal corner formwork mainly contains wooden internal corner formwork, bamboo glue internal corner formwork and steel internal corner formwork.The defects such as wooden internal corner formwork and bamboo glue internal corner formwork exist yielding or splitting, and high, the reusable number of times of coefficient of losses is few; Although steel internal corner formwork can overcome the above-mentioned defect of wooden internal corner formwork or bamboo glue internal corner formwork, but have that cost is high, heavy, easily cause the deficiencies such as cement products sur-face peeling when construction dismounting difficulty, easily corrosion, form removal.

Summary of the invention

In order to overcome the defect existing in prior art, the utility model aims to provide the plastic-steel hollow porous internal corner formwork that a kind of quality is light, cost is low, can be repeatedly used.

To achieve these goals, the utility model is by the following technical solutions: it comprises rectangular-shaped body, body is hollow structure, has some supporting ribs that are divided into a plurality of vestibules in the cavity of this body, and the vestibule that is positioned at this body corner is trapezoidal or semicircular structure; At two right-angle sides of body, respectively have one to vertically extending reinforcement rib inside right angle, there is connection projection each inner side of strengthening rib.

The corner of each vestibule is knuckle; Connection projection is trapezium structure; There is the dowel that connects two right-angle side inner sides in the corner of body.

Compared with the prior art, the utility model is owing to having adopted technique scheme, it is the main hollow loose structure of making that traditional internal corner formwork has been changed into by polyvinyl chloride (PVC) material, therefore both avoid wooden internal corner formwork and bamboo glue internal corner formwork is yielding or splitting, the few defect of high, the reusable number of times of coefficient of losses, overcome again the deficiencies such as steel internal corner formwork cost is high, heavy, construction dismounting difficulty, easy corrosion, form removal trouble; Not only have similar wood can saw, can dig, can bonding, available nail or the suitability for secondary processing such as screw is fixing, but also have hardness high, be difficult for strain cracking, acid-alkali-corrosive-resisting, the plurality of advantages such as mothproof, fire-retardant, quality is light, form removal is convenient, cost is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: body 1, supporting rib 2, vestibule 3, dowel 4, connection projection 5, reinforcement rib 6.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

As shown in Figure 1: rectangular-shaped body 1 is hollow structure, in the cavity of this body, there are some supporting ribs 2 that are divided into a plurality of vestibules 3; Wherein, the vestibule 3 that is distributed in 1 liang of right-angle side of body is square or rectangular configuration, the vestibule 3 that is distributed in body 1 corner for trapezoidal or (with) semicircular structure (being distributed in the present embodiment, the vestibule 3 of body 1 corner for trapezoidal and semicircle).At two right-angle sides of body 1, respectively have one to vertically extending ribbed 6 inside right angle, the inner side of each ribbed 6 have by fixture (not shown) and other template (not shown) fasten connect be connected projection 5.

For fear of stress, concentrate, at the corner of each vestibule 3, all adopt round-corner transition.

For fear of stress, concentrate, simultaneously also for the ease of connecting with described fixture, connecting projection 5 is trapezium structure.

In order to improve intensity and rigidity, in the corner of body 1, there is the dowel 4 of connection two right-angle sides inner sides.

The utility model surfacing is smooth, good toughness, intensity are high, and length can customize as required.
