Abstract
A segment with positioning cushions comprises concrete, a reinforcement cage and the positioning cushions. The segment is characterized in that the positioning cushions support the reinforcement cage by the aid of molds, the positioning cushions and the reinforcement cages are embedded into the cast concrete so that the segment is formed, and each positioning cushion consists of a positioning seat homogeneous with the concrete and a positioning socket which are connected fixedly. Compared with the prior art, the segment with the positioning cushions has the advantages that firm connection is realized since the positioning seats are homogeneous with the concrete; tensile strength of the segment is increased due to accurate positioning of the reinforcement cage, water seepage caused by deformation and ageing of plastic cushions is eliminated, and the reinforcement cage is effectively protected against rusting; further, the positioning cushions made of concrete are simple in process, low in cost and fine in durability, prolongs the service life of the segment, and avoids accident potential.
Description
Technical field
A kind of section of jurisdiction with spacer pad of the utility model, what relate to is the technical field of the underground space, is applied to construction of tunnel.
Background technology
Plastic cushion is generally all used in producing in domestic section of jurisdiction; yielding; can't guarantee protective layer thickness; and the aging back of plastic cushion produces the slit; between the slit easily the infiltration, the corrosion reinforcing cage reinforcing bar; cause the intensity of section of jurisdiction to descend, directly influence the application life of section of jurisdiction, quickened the existence of accident potential.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, according to the section of jurisdiction technical requirements, design a kind of limited bayonet and imbed the syndeton of positioning seat, reach the location deck and combine, can not produce a kind of section of jurisdiction with spacer pad because of infiltration corrosion reinforcing bar cage with the section of jurisdiction homogeneity.Its technology is achieved in that the structure that comprises concrete, reinforcing cage, spacer pad, it is characterized in that: spacer pad is by mould bearing bar cage, spacer pad, reinforcing cage are imbedded to water in the concrete of smashing and are formed the section of jurisdiction, and described spacer pad is by forming with the structure that the positioning seat of concrete homogeneity is fixedlyed connected with limited bayonet.Obvious advantage and the effect of implementing this technology are: at first overcome above-mentioned defective, because positioning seat and concrete homogeneity, it is firm to connect, because the accurate positioning of reinforcing cage has improved the compressive strength of section of jurisdiction, has stopped that plastic cushion is yielding, the generation of the aging infiltration phenomenon that is produced, guarantee that effectively reinforcing cage is not by corrosion, and concrete spacer pad technology is simple, and cost is low, good endurance, prolong the application life of section of jurisdiction, avoided the generation of accident potential.
Description of drawings,
Fig. 1 is a structural representation of the present utility model;
Wherein, 1-positioning seat, 2-limited bayonet, 3-section of jurisdiction, 4-reinforcing cage, 5-concrete, 6-spacer pad.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
See accompanying drawing 1, spacer pad 6 is by mould bearing bar cage 4, and spacer pad 6, reinforcing cage 4 are imbedded to water and formed section of jurisdiction 3 in the concrete of smashing 5, and spacer pad 6 is by forming with the structure that the positioning seat 1 of concrete 5 homogeneities is fixedlyed connected with limited bayonet 2.
See accompanying drawing 1, at first, the limited bayonet 2 of injection mo(u)lding is put into the mould of spacer pad 6, water the positioning seat of smashing with concrete 5 homogeneities 1, positioning seat 1 is fixedlyed connected with limited bayonet 2, spacer pad 6 was made in maintenance in 28 days.Reinforcing cage 4 is put into high-precision section of jurisdiction 3 to be watered and smashes mould; example; a spacer pad 6 to be set at a distance of the 400mm spacing; 4 limited bayonets 2 are snapped in respectively on four main muscle of reinforcing cage 4; positioning seat 1 bottom surface of spacer pad 6 is smash mould with watering of section of jurisdiction 3 respectively and is offseted; reinforcing cage 4 is accurately positioned watering and smashes in the mould; reinforcing cage 4 protective layer thickness errors are at ± 2mm; disturbing concrete 5; location deck 1 is combined, through steam curing 12 hours, the demoulding with section of jurisdiction 3 homogeneities; maintained 28 days, and made section of jurisdiction 3.
Claims (2)
1. section of jurisdiction with spacer pad comprises the structure of concrete, reinforcing cage, spacer pad, and it is characterized in that: spacer pad is by mould bearing bar cage, and spacer pad, reinforcing cage are imbedded to water in the concrete of smashing and formed the section of jurisdiction.
2. a kind of section of jurisdiction with spacer pad according to claim 1 is characterized in that: described spacer pad is by forming with the structure that the positioning seat of concrete homogeneity is fixedlyed connected with limited bayonet.
