Abstract

The utility model belongs to bridge bearings technical field, which discloses a seismic steel bearing. The utility model is mainly characterized in that the utility model comprises an upper bearing plate, a middle steel plate, a steel liner and a lower bearing plate. The steel liner is semicircular cylinder shaped or semi elliptical cylinder shaped. In the seismic steel bearing provided by the utility model, the steel liner is designed to be semicircular cylinder shaped or semi elliptical cylinder shaped, therefore, the steel liner has a radian in only one direction. The bearing can only rotate in an angle in the radian direction and can not rotate in the other direction, therefore, the special requirement of one-way rotation angle is met.

Description

The antidetonation steel support

Technical field

The utility model belongs to the bridge pad technical field, relates in particular to a kind of antidetonation steel support.

Background technology

In bridge construction, need to use bridge pad, and ball shaped steel bearing is widely used especially owing to the energy any rotation angle.But in the bridge design of some special occasions, need the bearing can only unidirectional corner, do not need comprehensive corner, this moment, ball shaped steel bearing just can not meet the needs of.

The utility model content

Problem to be solved in the utility model just provides a kind of antidetonation steel support that can only vertical or horizontal corner.

For addressing the above problem, the technical scheme that the utility model antidetonation steel support adopts is: comprise upper bracket plate, middle steel plate, steel liner plate and lower support plate, described steel liner plate is semicircle column type or semiellipse column type.

Its additional technical feature is: the suitable bridge of described steel liner plate is to setting.

Antidetonation steel support provided by the utility model compared with prior art, steel liner plate is designed to semicircle column type or semiellipse column type, steel liner plate only has radian in one direction like this, bearing can only produce corner in this radian direction, and cannot not be rotatable, thereby satisfied the specific (special) requirements of unidirectional corner in another direction.

Description of drawings

Fig. 1 is the direction across bridge structural representation of the utility model antidetonation steel support;

Fig. 2 is that the suitable bridge of antidetonation steel support is to structural representation;

Fig. 3 is the structural representation of steel liner plate.

The specific embodiment

Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model antidetonation steel support.

As shown in Figure 1, 2, the utility model antidetonation steel support comprises upper bracket plate 1, middle steel plate 2, steel liner plate 3 and lower support plate 4, and steel liner plate 3 is semicircle column type or semiellipse column type.As shown in Figure 3, steel liner plate 3 is the semiellipse column type, can certainly be the semicircle column type.

During use, when steel liner plate 3 along bridges when being provided with, the cross section of its direction across bridge is illustrated in figure 1 as arc, its along bridge to the cross section be illustrated in figure 2 as rectangle, like this, steel liner plate 3 can produce corner at direction across bridge, and along bridge to can not producing corner, thereby satisfy the specific (special) requirements of unidirectional corner.

Claims (2)

1. the antidetonation steel support comprises upper bracket plate, middle steel plate, steel liner plate and lower support plate, it is characterized in that: described steel liner plate is semicircle column type or semiellipse column type.

2. antidetonation steel support according to claim 1 is characterized in that: the suitable bridge of described steel liner plate is to setting.
