The utility model is used for land fan bulky concrete form.

Description

Land fan large-volume concrete formwork

The technical field is as follows:

the utility model relates to a land fan bulky concrete form.

Background art:

a large-volume concrete structure of a land wind turbine is a main stress structure of the wind turbine, and the quality of the concrete structure is very important for long-term safe and stable operation of the wind turbine. Because the environment of the fan is different, the mechanical property and the durability of the concrete structure are required to be high, and in the actual construction process, the construction process cannot meet the relevant standard requirements easily, so that the mechanical property and the durability of the mass concrete are reduced, and the large hidden danger is brought to the safe and stable operation of the fan.

In the production and processing processes of the common template, the size is not standard, so that the follow-up installation is not qualified, the distance between the common template and the reinforcing steel bar is not uniform, and the concrete construction quality can not be ensured under the condition that the thickness of the concrete protective layer is larger or smaller.

The connection of the templates is hard connection, the adjustment is difficult, the templates deform after long-time use, and the phenomena of unevenness, cracking, cellular pitted surface, cavities, exposed ribs, mold running, air holes, surface cracks, slurry leakage and the like occur on the surfaces, so that the quality of concrete is influenced.

The common die has no connection structure among all parts, is integrally bound and connected through the steel wire rope, needs a plurality of people to simultaneously carry out work in the construction process, has high construction difficulty, cannot meet the requirements of construction specifications, is difficult to adjust a template, and increases the labor cost.

The utility model has the following contents:

the utility model aims at providing a land fan bulky concrete form, through house type structure with guarantee the tolerance template, solved the stress state on circular basis.

The above purpose is realized by the following technical scheme:

a large-volume concrete template of a land fan is a circular structure formed by splicing a plurality of single templates, and two adjacent single templates are fixed through fixing bolts;

the single template is of an arc-shaped structure, and clamping arms are arranged at two ends of the single template.

The large-size concrete formwork of the onshore fan is characterized in that an included angle between the clamping arm and the tangential direction of the arc-shaped surface of the single formwork is an acute angle.

Has the advantages that:

1. the utility model discloses form by the concatenation of several standard tolerance's template monomer, applicable in the concrete foundation of different diameters, have better commonality, convenient equipment. Particularly, the arc-shaped member is adopted, so that the problem that a stress model of a polygonal structure is not ideal by adopting a common template in the prior art is solved.

2. The utility model discloses a have mechanical connection structure between each module, the piecemeal concatenation is more easy operation between the template that standardized tolerance is, reduces construction operating personnel, saves the cost, and simultaneously, the piecemeal is assembled and also can be ensured the concrete protective layer thickness between each part and the reinforcing bar, satisfies the construction specification requirement.

3. The utility model discloses through bolted connection between each monomer template, connect closely, stably, the leakproofness is better, has solved standardized template and has solved original ordinary template unevenness, fracture, exposed muscle, race mould, gas pocket, surface crack, low quality phenomena such as thick liquid leak, ensures concrete quality.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of portion A of FIG. 1;

FIG. 3 is a schematic diagram of the structure of a monomer template;

in the figure: 1. fixing the bolt; 2. clamping arms; 3. a monomer template; 4. the space is adjusted.

The specific implementation mode is as follows:

referring to fig. 1-3, a large-volume concrete formwork of a land fan is a circular structure formed by splicing a plurality of single formworks 3, and two adjacent single formworks are fixed through fixing bolts 1;

the single template is of an arc-shaped structure, and clamping arms 2 are arranged at two ends of the single template.

An included angle between the clamping arm and the tangential direction of the arc-shaped surface of the single template is an acute angle;

the space of centre gripping is adjustment space 4 between the arm lock of two adjacent monomer templates, as the concrete foundation to different diameters, adjusts the monomer template of different numbers and carries out the amalgamation, simultaneously when carrying out the amalgamation because the arm lock with the arc face tangential of monomer template between the contained angle be the acute angle for keep the laminating state between two adjacent monomer template terminal surfaces, the leakproofness is better, has solved phenomenons such as surface unevenness, fracture, honeycomb pitted surface, cavity, exposed rib, running mould, gas pocket, surface crack, hourglass thick liquid, ensures the concrete quality.

The clamping arm between two adjacent monomer templates is fixed through the fixing bolt, so that the fixed positions of the two monomer templates can be kept unchanged, and the stability after fixing is guaranteed.

Claims (2)

1. The utility model provides a large volume concrete template of land fan, characterized by: the template is a circular structure formed by splicing a plurality of single templates, and two adjacent single templates are fixed through fixing bolts;

the single template is of an arc-shaped structure, and clamping arms are arranged at two ends of the single template.
