Abstract
The utility model discloses a plastic steel hollow porous external corner template and belongs to a section bar used for producing a cast-in-place concrete die and is aimed at providing the external corner template which is light in weight and low in cost and is reusable for multiple times. The plastic steel hollow porous external corner template comprises a right-angle-shaped body. The body (1) is of a hollow structure. Supporting ribs (2) used for separating an empty cavity into multiple hole cavities (3) are arranged in the empty cavity of the body. The hole cavities (3), disposed at the corner of the body, are of trapezoid or semi-circular structures. At least two reinforcing ribs (4), which vertically extend outside right angles, are respectively arranged at two right angle edges of the body (1). Connection projections (5) are arranged at insides of the reinforcing ribs (4) respectively disposed at right-angle ends of the body (1). The plastic steel hollow porous external corner template is simple in structure, high in hardness, light in weight and convenient in form removal and is not easily deformed or cracked and is acid-base corrosion-resistant, mothproof and anti-flaming and is the novel section bar capable of replacing a wooden external corner template, a bamboo external corner template or a steel external corner template.
Description
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 external angle formwork for cast-in-situ concrete.
Background technology
External angle formwork is a kind of section bar of making concrete casting injection molding corner, and the quality of its quality directly affects the quality of engineering construction.At present, widely used external angle formwork mainly contains wooden external angle formwork, bamboo glue external angle formwork and steel external angle formwork.The defects such as wooden external angle formwork and bamboo glue external angle formwork exist yielding or splitting, and high, the reusable number of times of coefficient of losses is few; Although steel external angle formwork can overcome the above-mentioned defect of wooden external angle formwork or bamboo glue external angle 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 external angle 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; Two right-angle sides at body have respectively at least two reinforcement ribs that extend to right angle outside vertical; Wherein, there is connection projection the inner side that lays respectively at the reinforcement rib of body two terminations, right angle.
The corner of each vestibule and the junction of respectively strengthening rib and body are knuckle; Connection projection is trapezium structure.
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 external angle formwork has been changed into by polyvinyl chloride (PVC) material, therefore both avoid wooden external angle formwork and bamboo glue external angle 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 external angle 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, reinforcement rib 4, connection projection 5.
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 two reinforcement ribs 4 that extend to right angle outside vertical, and lay respectively at inner side that those two of termination, 1 liang of right angle of body strengthen ribs 4 have by fixture (not shown) and other template (not shown), fasten connection be connected projection 5.
For fear of stress, concentrate, the corner of each vestibule 3 all adopts round-corner transition; In like manner, each junction of strengthening rib 4 and body also adopts knuckle.
For fear of stress, concentrate, simultaneously also for the ease of connecting with described fixture, connecting projection 5 is trapezium structure.
The utility model surfacing is smooth, good toughness, intensity are high, and length can customize as required.
Claims (3)
1. a plastic-steel hollow porous external angle formwork, comprise rectangular-shaped body, it is characterized in that: body (1) is hollow structure, in the cavity of this body, have some supporting ribs (2) that are divided into a plurality of vestibules (3), the vestibule (3) that is positioned at this body corner is trapezoidal or semicircular structure; Two right-angle sides at body (1) have respectively at least two reinforcement ribs (4) that extend to right angle outside vertical; Wherein, there is connection projection (5) inner side that lays respectively at the reinforcement rib (4) of body (1) two termination, right angle.
2. plastic-steel hollow porous external angle formwork according to claim 1, is characterized in that: the corner of each vestibule (3) and respectively strengthen rib (4) and be knuckle with the junction of body (1).
3. plastic-steel hollow porous external angle formwork according to claim 1 and 2, is characterized in that: connect projection (5) for trapezium structure.
