Abstract

The utility model discloses a horizontal web member formula prestressed concrete pillar, it includes that mid portion is the pillar body and the prestressing force owner muscle of setting in pillar body inside of I shape, all there is a chamfer plane in the bight at four exterior angles of pillar body, and this chamfer plane is the obtuse angle with the plane included angle at two limits places at this angle respectively. The in -process of putting into production, loading and unloading, consolidating and transport for long -distance, the utility model discloses a pillar four corners is difficult to damage, also no longer causes the injury to the staff who scrambles the pillar.

Description

Horizontal web member formula prestressed concrete pillar

Technical field

The utility model relates to electrification railway contact net facility, particularly relates to a kind of horizontal web member formula prestressed concrete pillar.

Background technology

At present, China's electric railway distance travelled has reached more than 20,000 kilometers, nearly 1,000,000 of the concrete pillar of use, and wherein more than 90% is horizontal web member formula prestressed concrete pillar (hereinafter referred to as square pillar).

Fang Zhizhu is in process of production because limiting by existing mold, the corner of prefabricated shaping back prop is acute angle or right angle, and in production, handling, reinforcing and long-distance transport process, pillar corner very easily produces damage, cause product to produce open defect, serious causing scraps.And in the later stage of pillar uses, when installing or overhaul the equipment of column upper section, constructor needs free-hand climbing pillar, and sharp-pointed corner is also easy causes minor injury to constructor, there is potential safety hazard.

Utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of horizontal web member formula prestressed concrete pillar is provided, in production, handling, reinforcing and long-distance transport process, this pillar corner is not easy to damage, and also no longer damages the staff of climbing pillar.

For achieving the above object, technical solution of the present utility model is: a kind of horizontal web member formula prestressed concrete pillar, and it comprises mid portion is the pillar body of I shape and the main muscle of prestressing force being arranged on pillar body interior; It is characterized in that, there is a chamfer plane in the bight at four exterior angles of described pillar body, and this chamfer plane is obtuse angle with the plane included angle at the place, two limits at this angle respectively.

After product is carried out chamfering, product can be reduced in a large number at production, transport and erection stage to the unexpected injury of product pillar corner, minimizing product defects and maintenance cost; And can unexpected injury to people in corresponding minimizing later stage use procedure; Significantly can improve the aesthetics of product appearance.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the present embodiment comprises pillar body 1 that mid portion is I shape and is arranged on the main muscle of prestressing force of pillar body 1 inside.There is a chamfer plane 2 in the bight at four exterior angles of pillar body 1, and this chamfer plane 2 is obtuse angle with plane included angle α and β at the place, two limits 3 and 4 at this angle respectively.

Above-described embodiment is only preferred and exemplary, and those skilled in the art can carry out the improvement of equivalent technologies according to the description of this patent, it is all in the protection domain of this patent.
