Description

Special formwork for small diameter circular columns

technical field

The utility model relates to a concrete construction template, in particular to a special template for small-diameter circular columns.

Background technique

In the formwork support process of circular columns, the commonly used formwork is wooden strip assembly formwork or shaped steel formwork. The wood strip assembly formwork is manually assembled wooden strips outside the iron sheet, which is inefficient, has large errors, and is easy to be damaged during the demolition process. After one use, it is necessary to manually replace and reinforce the spliced wooden strips, and repair and polish the cylinder; The shaped steel formwork needs to be ordered by the factory, which takes a long time and is heavy. Lifting equipment is required for hoisting and the cost is high.

Utility model content

The technical problem to be solved by the utility model is to provide a special formwork for small-diameter circular columns, which is quick and convenient to construct, and the poured concrete can achieve clear water effect without repairing and grinding.

The utility model solves the technical problem of the small-diameter circular column special formwork, including two PVC semicircular pipes, and the two sides of the PVC semicircular pipes parallel to the length direction are provided with strip flanges. The strip method The flange is provided with a plurality of first connecting holes, and the two PVC semicircular pipes are connected into a cylindrical pipe through a connecting piece passing through the first connecting holes.

Further, the two ends of the PVC semicircular pipe perpendicular to the length direction are provided with arc-shaped flanges, and the arc-shaped flanges are provided with a plurality of second connection holes.

Further, the arc-shaped flange is riveted on the PVC semicircular pipe through rivets.

Further, the strip flange is riveted on the PVC semicircular pipe through rivets.

Further, the strip flange is made of angle steel.

Further, arc-shaped ribs are provided on the outer surface of the PVC semicircular pipe.

Further, there are at least two curved ribs.

Further, the arc ribs are welded on the strip flanges.

Further, the connecting piece is a buckle.

Further, the connecting piece is a U-shaped buckle.

The beneficial effects of the utility model are:

1. The formwork is closely connected, with less splicing and less seams. The poured concrete cylinder is not only smooth but also well formed, which can achieve the effect of clear water;

2. The formwork can be quickly installed on the construction site through simple processing, and the construction is convenient and fast; because the semi-circular pipe made of PVC material is light in weight, easy to support the formwork, and does not require hoisting equipment, the construction speed can be improved;

3. After grouting, there is no running out of grout, no bursting of the mold, and only need to disengage the buckle of the formwork when demoulding.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figures 1 to 3, the special formwork for small-diameter circular columns of the present invention includes two PVC semicircular pipes 1, and strip flanges 3 are arranged on both sides of the PVC semicircular pipes 1 parallel to the length direction. , the strip flange 3 is provided with a plurality of first connecting holes 4, and the two PVC semicircular pipes 1 are connected into a cylindrical pipe through a connecting piece passing through the first connecting holes 4.

Wherein, the small-diameter circular column refers to a circular column with a diameter ≤ 500 mm. The strip flange 3 is provided to connect the two PVC semicircular pipes 1 into a cylindrical shape, and the first connecting hole 4 is provided for the convenience of connection. The two PVC semicircular pipes 1 can be connected into a cylindrical pipe by using a connecting piece. The formwork can be quickly installed on the construction site through simple processing, and because the semicircular pipe made of PVC material is not only light in weight, but also easy to handle and assemble, and does not require hoisting equipment, which can increase the construction speed; due to the assembly of two semicircular pipes As a formwork, there are few seams, and the inner surface of the PVC semicircular pipe is very smooth. The poured concrete is not only smooth but also well formed, and can achieve the effect of clear water without repairing and polishing; it is also wear-resistant and has a long service life; when demoulding, only need The template can be disassembled by removing the connecting piece, which is convenient and quick.

In order to facilitate the splicing of the upper and lower ends of the special formwork for multiple small-diameter circular columns to adapt to pouring circular columns of different heights, as a preferred embodiment, the two ends of the PVC semi-circular pipe 1 perpendicular to the length direction are provided with arcs. The arc-shaped flange 2 is provided with a plurality of second connection holes 5 . The upper and lower two small-diameter circular column special formworks can be connected by using the connecting piece to pass through the second connecting hole 5 .

The arc-shaped flange 2 can be connected to the PVC semi-circular pipe 1 by bolts, screws, etc., but for the sake of simple structure and convenient connection, as a preferred embodiment, the arc-shaped flange 2 is riveted on the PVC semi-circular pipe 1 by rivets. superior.

The strip flange 3 can be connected to the PVC semicircular pipe 1 by bolts, screws, etc., but for the sake of simple structure and convenient connection, as a preferred embodiment, the strip flange 3 is riveted on the PVC semicircular pipe 1 by rivets. superior.

In order to facilitate the connection of two PVC semicircular pipes 1 and maintain sufficient strength, as a preferred embodiment, the strip flange 3 is made of angle steel.

In order to further increase the strength of the special formwork for small-diameter circular columns, as a preferred embodiment, the outer surface of the PVC semicircular pipe 1 is provided with arc-shaped ribs 6 . As a preferred embodiment, there are at least two curved ribs 6 . A plurality of curved ribs 6 are evenly distributed on the PVC semicircular pipe 1 along the length direction.

The arc-shaped rib 6 can be directly riveted on the PVC semicircular pipe 1 , and as a preferred embodiment, the arc-shaped rib 6 is welded on the strip flange 3 . Like this, just can not cause harm to the PVC semicircular pipe 1.

In order to facilitate connection, as a preferred embodiment, the connecting member is a buckle. Further, the connecting piece is a U-shaped buckle. In this way, it is not easy to fall off after being stuck.
