Abstract

The utility model relates to a timber formwork for pouring cylindrical columns, which comprises a cylindrical timber mold formed by a plurality of perpendicular battens. The timber formwork is characterized in that a plywood is lined on the inner side of the timber mold, the outer side of the timber mold is sleeved with multiple layers of batten groups from top to bottom, each batten group is formed by a plurality of battens distributed uniformly, the inner side surface of each batten which is arc-shaped can cling to the timber mold, and the battens in the upper and lower batten groups are in staggered arrangement. The timber formwork has the advantages that as the outer side of the timber mold is provided with the multiple layers of batten groups clinging to the timber mold and the battens in the upper and lower batten groups are in staggered arrangement, the timber mold is uniform in stress without affecting quality of poured cylindrical columns. The timber mold is further sleeved with stirrups for fastening the timber mold, thereby being capable of properly reducing outer periphery supporting points, and reducing pouring occupation area.

Description

A kind of cylindrical column cast wooden form

Technical field

The utility model relates to a kind of wooden form, is used to pour into a mould the wooden form of cylindrical column in particularly a kind of builing industry.

Background technology

In building operations, usually need to pour into a mould cylindrical column, the cast template structure of traditional cylindrical column and common rectangular cylinder template are basic identical, and promptly the template of the type of imitating with the cylinder that needs cast is used in the inboard, and establish the bracing frame of support shuttering in the outside of template.It exists shortcoming to be: the bracing frame that need set up is more, accounts for area, and the discontinuity of template, and the easy deformation and the mould that rises influence casting quality.

The utility model content

The technical problems to be solved in the utility model provides a kind of stressed even and not space consuming cylindrical column cast wooden form.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of cast wooden form of cylindrical column, include the cylindrical wooden model that some vertical battens are formed, its innovative point is: the inboard of described wooden model is lined with veneer, the outside is with several layers of flitch group from top to bottom, described flitch group is made of several uniform flitches, the circular arc of the medial surface of described flitch for being close to wooden model, and described upper and lower flitch group flitch each other is staggered and arranges.

Further, be with the stirrup of fastening wooden model on the wooden model of described every layer of flitch group upper surface.

Advantage of the present utility model is: the outside by wooden model is provided with the several layers of flitch group of being close to wooden model, and upper and lower flitch group flitch each other is staggered and arranges, make wooden model stressed evenly, do not influence the cylindrical column quality that cast is come out.Also be with the stirrup of fastening wooden model on the wooden model, can suitably reduce the peripheral strong point, the floor space that reduces to pour into a mould.

Description of drawings

Fig. 1 is the structural representation of the utility model cylindrical column cast with wooden form.

Fig. 2 is along the sectional view of A-A line among Fig. 1.

Fig. 3 is the structural representation of stirrup in the utility model.

The specific embodiment

As shown in Figure 1, 2, 3, comprise wooden model 1, veneer 2, flitch group 3, stirrup 4.

Above-mentioned wooden model 1 by some vertical battens form one cylindrical, the inboard of this wooden model is lined with veneer 2, the outside is with several layers of flitch group 3.Every layer of flitch group 3 is evenly distributed on wooden model 1 outside by several flitches 5 and constitutes, the medial surface of described flitch 5 is the circular arc of wooden model 1 lateral surface of can fitting, it is fixedlyed connected with the lateral surface of wooden model 1 by screw, each flitch group 3 flitch 5 each other is staggered arranges, and makes the stressed more even of whole wooden model 1.Be with stirrup 4 on the wooden model 1 of every layer of flitch group 3 upper surface, be used for whole fastening wooden model 1, also support bar can be set according to circumstances outside the flitch group 3.Adopt the wooden form cast cylindrical column of this structure, wooden model when cast stressed evenly, can not produce quality influence to the cylinder of cast.

Claims

1. a cylindrical column is poured into a mould and is used wooden form, include the cylindrical wooden model that some vertical battens are formed, it is characterized in that: the inboard of described wooden model is lined with veneer, the outside is with several layers of flitch group from top to bottom, described flitch group is made of several uniform flitches, the circular arc of the medial surface of described flitch for being close to wooden model, and described upper and lower flitch group flitch each other is staggered and arranges.

2. wooden form is used in cylindrical column cast according to claim 1, it is characterized in that: the stirrup that is with fastening wooden model on the wooden model of described every layer of flitch group upper surface.
