Abstract
The utility model discloses a cement concrete pillar and construction method, pack cement concrete including at least 2 sections cement concrete pillar festival sections and the shell of parcel on cement concrete pillar, cement concrete pillar festival section in including 2 at least parallels and isometric steel pipe, fixed through horizontal union coupling between the steel pipe, ring flange and lower flange dish have been welded respectively to the upper and lower both ends of cement concrete pillar festival section, are connected through last ring flange and lower flange dish between the cement concrete pillar festival section. The utility model discloses an effect lies in tying has economized the material, has also alleviateed cement concrete pillar's weight. Simultaneously, use the mode of multistage cement concrete festival section connection for the construction is convenient more easy.
Description
Technical field
The utility model relates to road and bridge building trade, is specifically related to a kind of cement concrete pillar and construction method thereof.
Background technology
Existing road and bridge building trade, what the construction method of cement concrete pillar generally adopted is take reinforcing bar as skeleton, is then equipped with supporting post mould casting cement concrete.
Publication number is that CN103088964A discloses a kind of steel pipe foam cement concrete combination column and construction method thereof, comprise a root post body, column body comprises steel pipe, the foam cement concrete be cast in steel pipe, be arranged in steel mesh reinforcement on outer wall of steel pipe and outsourcing cement concrete layer, be connected with flange bellmouth by flange between steel pipe, be placed with pad between flange and flange bellmouth, wherein foam cement concrete can adopt Fly ash foam cement concrete or haydite foam cement concrete.
The shortcoming of prior art is that own wt is too large, and the material of at substantial.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is that proposing one can reduce own wt and save the easy cement concrete pillar of material construction and construction method thereof.
For reaching above-mentioned effect, concrete scheme of the present utility model is as follows:
A kind of cement concrete pillar, comprise at least 2 sections of cement concrete pillar sections, joined end to end by flange between each cement concrete pillar sections, its key is: described cement concrete pillar sections comprises at least two steel pipes be welded in parallel between upper flange plate and lower flange, filling concrete concrete in steel pipe, steel pipe two ends are evenly distributed on flange circumferentially.
Adopt cement concrete pillar sections composition, because each section of cement concrete pillar weight is little, alleviate difficulty of construction; Steel duct filling concrete concrete enhances the support strength of steel pipe, and what drastically reduce the area cement concrete uses doses simultaneously.
Further, be welded and fixed by transverse tube between described steel pipe, the shearing between steel pipe can be enhanced.
Further, welding between the described upper flange plate of adjacent described cement concrete pillar sections and lower flange and by screw bolt reinforcing, and be surrounded by shell outside cement concrete pillar sections.Making cement concrete pillar sections two ends be provided with flange makes the connection between cement concrete pillar sections convenient.
Preferably, described cement concrete pillar sections is welded with three steel pipes by the even circumferential distribution of flange.Three steel pipes are evenly distributed on flange and form Triangle-Profile, can improve the stability of cement concrete pillar.
Further, described lower flange and upper flange plate are provided with three circular holes, and the position of circular hole is corresponding with the position of steel pipe, is provided with wire lath in circular hole.
Its effect is that wire lath can the concrete bond strength of refinforced cement, makes the connection of each cement concrete pillar sections more firm.
Preferably, the cross section of described steel pipe and flange is all circle, and its diameter ratio is 1:3, and steel pipe is near the edge of flange.Its effect is to impact the bearing strength of cement concrete pillar again by the amplitude peak consumption that reduces mixed earth simultaneously.
Preferably, described cement concrete pillar segmental length is 2 meters.Its effect is the cement concrete pillar that arbitrarily can mix into arbitrary height according to the needs of actual conditions.
Remarkable result of the present utility model: replace the reinforcing bar of prior art with steel pipe, and in steel pipe filling concrete concrete, only fix with transverse tube between steel pipe, knot has economized material, also mitigates the weight of cement concrete pillar.Meanwhile, the mode using multistage cement concrete sections to connect, makes construction easily convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of cement concrete pillar, the circular housing 6 comprising adjacent two sections of cement concrete pillar sections 9 and be wrapped on cement concrete pillar; This circular housing 6 is fixed along the edge of flange.The lower end of each section of cement concrete pillar sections 9 is welded with lower flange 2a upper end and is welded with upper flange plate 2b, is joined end to end between adjacent two sections of cement concrete pillar sections 9 by lower flange 2a and upper flange plate 2b.First be fixedly connected with bolt between upper flange plate 2b and lower flange 2a, the edge then along upper flange plate 2b and lower flange 2a welds.
Cement concrete pillar sections 9 comprises three round steel pipes 3, and steel pipe 3 is evenly distributed on flange circumferentially, and distribute in triangle disposition, the two ends up and down of steel pipe are welded on upper flange plate 2b and lower flange 2a respectively.The diameter of steel pipe 3 and the diameter ratio of flange are 1:3, filling concrete concrete in steel pipe.Fixed by transverse tube 1 reinforcement of weld between steel pipe 3, the both ends horizontal of transverse tube is welded on the outer wall of adjacent two steel pipes 3.Cement concrete pillar sections 9 length is 2 meters.
Lower flange 2a and upper flange plate 2b is provided with three circular holes 7, and the position of circular hole 7 and the position of steel pipe 3 are corresponding to distribute equally in triangle disposition, and circular hole is also provided with wire lath 8.
The construction method of above-mentioned cement concrete pillar is as shown in Figure 4:
(1) cement concrete pillar sections step is made:
The even circumferential distribution of the two ends of three steel pipes 3 by flange is welded on upper flange plate 2b and lower flange 2a respectively, described flange is provided with the circular hole corresponding with the position of steel pipe.Transverse tube reinforcement of weld used each other by steel pipe, and the two ends of transverse tube respectively horizontal welding are connected on the outer wall of adjacent two steel pipes 3;
(2) cement concrete pillar is made:
From ground, erect first cement concrete pillar sections, and to the filling cement of this cement concrete pillar sections;
The upper flange plate 2b of first cement concrete pillar sections fixes the lower flange 2a of second cement concrete pillar sections, first connect through bolt between upper flange plate 2b and lower flange 2a, again the edge of these upper and lower two flange is welded, again to second cement concrete pillar sections placing cement concrete, by that analogy, until complete the cement concrete placing of a cement concrete pillar sections topmost;
(3) spary anti-corrosion material: column outer wall is propped up to whole cement concrete and carries out anti-corrosion material spary;
(4) shell is wrapped up: by flange outer, to whole cement concrete pillar parcel shell.
