Abstract

The utility model relates to a glass fiber reinforced plastics cylindrical formwork capable of being spread in the radial direction, which is characterized in that connections between the formwork bodies are U-shaped edgings, a left and a right channel steels are respectively fixed in the two U-shaped edgings by screw bolts and nuts, and the connections are fixed by the screw bolts and nuts, the top end of the formwork is provided with a circular post tie which is made of angle steels, four U-shaped ear rings are homogeneously distributed on the front surface of the circular post tie, and two semi-circular post ties are arranged on the bottom surface, and the middle portion thereof is fixed by screw bolts and the nuts. The glass fiber reinforced plastics cylindrical formwork capable of being spread in the radial direction has simple manufacturing technique and low cost, compared with a traditional forming circular post tie, the formwork of the utility model has the advantages of low cost, convenient transportation, light weight, convenient assembly, wear resistance and alkali resistance, smooth surface, rapid construction, more turnover number, post quality guaranteeing and the like.

Description

Radially deployable type Fiberglass in Round Column Formwork

Technical field

The utility model relates to the template that a kind of construction work is used, especially radially deployable type Fiberglass in Round Column Formwork.

Background technology

At present, in construction work concrete cylindrical work progress, though the used template of tradition has wooden form, steel work tubular template, glass fiber reinforced plastic tubular template, these several templates to obtain using widely, but the shortcoming that has oneself separately. wooden form is to utilize narrower batten to be combined into circular arc, though do not take machinery in the work progress, but because seam is too many, cause assembly unit speed slow, take a lot of work, the template number of turnover of assembly unit is low, also expend a large amount of timber, do not meet the industrial policy that country saves the timber energy; And because the seam of assembled formwork is too many, though the concrete cylindrical of cast has a lot of vestiges. the steel work template number of turnover is many, but because its quality is bigger, expend great amount of manpower and machinery expenses in the assembly unit process, assembly unit speed is slow, work efficiency is low, this template expends a large amount of steel, the cost height, the construction costs height is simultaneously because this template all is that two semicircles are assembled into cylinder type, and short transverse is by the more piece assembly unit, so the concrete cylindrical of construction vertically has two seams, and many seams are radially arranged, so the cylinder of construction has two vertical and many horizontal vestiges; The similar steel form of glass fiber reinforced plastic tubular formwork structure, this template construct need be made different heart moulds in advance according to the variation of pillar diameter and height, cause high because of the heart is molded, and template is shaped, need certain thickness and reinforcement, so manufacturing cost height, cause construction costs to improve. simultaneously, because having scholar, glass fiber reinforced plastics composite material becomes characteristic, so the glass fibre reinforced plastic cylinder mould is in transportation, install, deposit in the process yielding, assemble back tubular low precision, cause the cylinder low precision of cast, influence construction quality. and the cylinder of this template construction vertically also has two seam vestiges.

The utility model content

In order to overcome the deficiency that existing templates exists, the utility model provides a kind of novel radially deployable type Fiberglass in Round Column Formwork, this radially deployable type Fiberglass in Round Column Formwork has solved conventional template construction concrete cylindrical the technical problem that cylinder complicated, construction is of low quality, template construct speed is slow, consumptive material big, transportation is inconvenient, recycling rate of waterused is low, the template cost is high has been installed.

The technical scheme that its technical problem that solves the utility model adopts is: radially deployable type Fiberglass in Round Column Formwork, it is that the junction of template body is U type flanging respectively, be fixed with left channel-section steel and right channel-section steel with bolt, nut in the two U type flangings, the junction is fixed with bolt, nut, its top has angle steel to make circular tie, four U type earrings of even branch are arranged above the circular tie, and there are two semicircle ties the bottom surface, fixes with bolt, nut in the middle of it.

The utility model is according to hydromechanical principle, at engineering site, with thickness uniformly and can launch and closed glass fiber reinforced plastic plate body closure, surround the approximate cylinder of sealing, behind the fluid concrete, plate body is under the effect that is subjected to from the chutable concrete tension of inside, and the cylindrical shell radial section inside of sealing can be subjected to the identical normal stress of size, and all approximate cylinder body portions will inevitably rise into by the circular cylinder body of standard.

Radially deployable Fiberglass in Round Column Formwork is fixed with channel-section steel at plate body flanging place, along flanging and channel-section steel equally distributed bolt hole is arranged, make the plate body closure by the bolt connection. plate body circle Qu Jingdu height, inner surface is smooth, the concrete cylindrical of construction has only a vertical abutment joint vestige. the radially deployable Fiberglass in Round Column Formwork of the utility model dispatch from the factory and transportation in be that expansion shape can tabular, also can be irregular circular-arc, closed at the construction field (site) assembling, straightening.

The beneficial effects of the utility model are, this radially deployable type Fiberglass in Round Column Formwork, fundamentally having solved conventional template and added the error of man-hour in circularity control. radially deployable shape Fiberglass in Round Column Formwork length of run is exactly the cylinder girth, the height of cylinder highly just. therefore, manufacture craft is simple, cost is low, compare with traditional shaping column-form have that cost is low, convenient transportation, in light weight, easy to assembly, wear, alkali resistant, smooth surface, speed of application is fast, the number of turnover is many, ensure advantages such as cylinder quality.
