Abstract
The utility model belongs to the technical field of expansion joints, and discloses a bridge expansion device, which has the main technical characteristics that vertical steel plates, that are arranged in pair and provided with anchor bolts, are included; the vertical steel plates are bent; a rubber body integrated with the vertical steel plates is arranged between the vertical steel plates arranged in pair; the rubber body is integrated with the upper parts of the vertical steel plates; a stiffening horizontal steel plate is arranged in the rubber body; the middle of the rubber body takes the shape of an arch with a flat top surface; and grooves are formed on the top surface of the rubber body. In the bridge expansion device, the bent vertical steel plates are in contact with bridge body concrete to serve the supporting function; the bent vertical steel plates and the rubber body are integrated into a whole, so that the expansion device has good leak tightness, and can achieve functions of displacement, vehicle running and watertightness. The stiffening horizontal steel plate improves the carrying capacity of the expansion device. The expansion device has the advantages of whole firmness, smooth surface, attractive appearance, and good expansion, waterproof, dustproof, shock-absorbing and noise-reducing functions.
Description
Technical field
The utility model belongs to the shrinkage joint technical field, relates in particular to a kind of bridge extension joint.
Background technology
Need to install stretching device in the bridge construction.Current stretching device comprises the shaped steel that has groove of paired setting, is provided with rubber weather strip between shaped steel.This stretching device rubber strip is V-shaped, and there is groove fit protruding and shaped steel at two ends, fits or top pressure increase as off size, can rubber weather strip be pulled out, and waterproof is impacted.
The utility model content
The technical problem that the utility model will solve just provide a kind of firmly, good airproof performance and bridge extension joint attractive in appearance.
For addressing the above problem, the technical scheme that the utility model adopts is: comprise the upright steel plate of the paired setting that has anchor bolt, described upright steel plate is a bending-like, is provided with the rubber bodies that is connected as a single entity with upright steel plate between the upright steel plate that is provided with in pairs.
Its additional technical feature is: the top of described rubber bodies and upright steel plate is connected as a single entity; Be provided with the plain plate of putting more energy in the described rubber bodies; The middle part of said rubber bodies is the arch on plane for end face; The end face of said rubber bodies has groove.
A kind of bridge extension joint that the utility model provided; In the end of the beam body that is provided with in pairs or beam body and the platform end of carrying on the back; The upright steel plate of two bending-likes is set in pairs, be provided with between the upright steel plate of bending-like with upright steel plate through the sulfuration or the bonding rubber bodies that is connected as a single entity.Like this, the upright steel plate of bending contacts with the beam body concrete, and supporting is provided, and the upright steel plate of bending-like becomes as a whole with rubber bodies, makes can satisfy displacement, driving, waterproof effect by the stretching device good airproof performance.When the stretching device pressurized or when being drawn, the rubber physical efficiency is connected with the upright steel plate of bending-like securely, is not stripped from and draws back, and is safe and reliable.And be provided with the plain plate of putting more energy in the rubber bodies, then improved the supporting capacity of stretching device.The middle part of rubber bodies is the arch on plane for end face, and stretching device integral body is firm, surfacing, good looking appearance.The end face of rubber bodies has groove, and flexible, waterproof and dustproof and damping noise reduction effect are better.During installation anchor bolt is connected with beam body reinforcing bar, reinforces.The bridge extension joint segmentation is manufactured, and fills waterproofing materials between adjacent two sections, fixes with connecting bolt.
Description of drawings
Fig. 1 is the structural representation of a kind of bridge extension joint of the utility model.
The specific embodiment
Explain further details below in conjunction with the structure of accompanying drawing to a kind of bridge extension joint of the utility model.
As shown in Figure 1; A kind of bridge extension joint that the utility model provided comprises the upright steel plate 1 of the bending-like of paired setting, and upright steel plate 1 has anchor bolt 2, and upright 1 of the steel plate of the bending-like that is provided with in pairs is provided with the rubber bodies 3 that is connected as a single entity with upright steel plate 1; Rubber bodies 3 is connected as a single entity with the top of upright steel plate 1; Be provided with the plain plate 4 of putting more energy in the rubber bodies 3, the middle part of rubber bodies 3 is the arch on plane for end face, and the end face of rubber bodies 3 has groove 5.
A kind of bridge extension joint that the utility model provided; In the end of the beam body that is provided with in pairs or beam body and the platform end of carrying on the back; The upright steel plate 1 of two bending-likes is set in pairs, 1 of the upright steel plate of bending-like be provided with upright steel plate 1 through the sulfuration or the bonding rubber bodies that is connected as a single entity 3.Like this, the upright steel plate 1 of bending contacts with the beam body concrete, and supporting is provided, and 3 one-tenth of the upright steel plate 1 and the rubber bodies of bending-like are as a whole, make can satisfy displacement, driving, waterproof effect by the stretching device good airproof performance.When the stretching device pressurized or when being drawn, rubber bodies 3 can be connected with the upright steel plate 1 of bending-like securely, is not stripped from and draws back, and is safe and reliable.And be provided with the plain plate 4 of putting more energy in the rubber bodies 3, then improved the supporting capacity of stretching device.The middle part of rubber bodies 3 is the arch on plane for end face, and stretching device integral body is firm, surfacing, good looking appearance.The end face of rubber bodies 3 has groove 5, and flexible, waterproof and dustproof and damping noise reduction effect are better.During installation anchor bolt 2 is connected with beam body reinforcing bar, reinforces.The bridge extension joint segmentation is manufactured, and fills waterproofing materials between adjacent two sections, fixes with connecting bolt.
