Abstract
The utility model relates to a three-dimensional expansion device for bridge construction. The three-dimensional expansion device comprises a main toothed plate 5, an auxiliary toothed plate 7, an embedded anchoring device, a connecting bolt 1, a U-shaped waterproof rubber strip 4 and a rubber strip clamping plate 6, the three-dimensional expansion device is improved in that bolt holes 2 are arranged on the main toothed plate 5 and the auxiliary toothed plate 7, a sleeve 3 is arranged on the embedded anchoring device, and an internal thread is arranged on the sleeve 3; one end of the connecting bolt 1 is fixed in the sleeve 3 of the embedded anchoring device, and the other end of the connecting bolt 1 penetrates through the bolt holes 2 of the main toothed plate and the auxiliary toothed plate and are anchored by nuts; aligning holes matched with the bolt holes 2 are arranged on the rubber strip clamping plate 6, and two sides of the U-shaped waterproof rubber strip 4 are fixed on the embedded anchoring device through the rubber strip clamping plate 6. The three-dimensional expansion device has simple structure and obvious effects such as water resistance, dust prevention, noise control, skid prevention and bumping prevention and can be widely used for various bridges.
Description
Technical field
The utility model belongs to the bridge extension joint technical field.Be specifically related to be used for the three-dimensional stretching device of bridge construction.
Background technology
In bridge design, stretching device is the bridge critical piece, and is in concrete-bridge, loosening easily or cut off destruction such as cause that tooth plate comes off through the anchor bolt of effect repeatedly of vehicle.Simultaneously, because the rotation of the uneven and beam-ends of concrete leveling layer below the tooth plate, occur easily coming to nothing at flexible slip end tooth, problem such as broken teeth; Can cause problems such as the not good noise of road-ability is big, jumping car.In use also can enter dust and foreign material easily, owing to the structure reason can not be removed these deposits fully, draining in time will cause damage to stretching device in flexible process.
The utility model content
In order to solve problems such as bolt anchoring rapid wear that the board-like stretching device of present domestic steel comb exists, broken teeth, the utility model provides the three-dimensional stretching device that is used for bridge construction.
Concrete technical solution is as follows:
The three-dimensional stretching device that is used for bridge construction, comprise main tooth plate 5, secondary tooth plate 7, pre-buried anchor device, connecting bolt 1, U type waterproof adhesive tape 4, adhesive tape pressing plate 6, improvement is: described main tooth plate 5 and secondary tooth plate 7 are provided with bolt hole 2, pre-buried anchor device is provided with sleeve 3, and sleeve 3 is provided with internal thread; One end of described connecting bolt 1 is fixed on 3 li in the sleeve of pre-buried anchor device, and the other end passes the bolt hole 2 nut anchoring on the major and minor tooth plate, and described U type waterproof adhesive tape 4 both sides are fixed on the pre-buried anchor device with adhesive tape pressing plate 6.
Described adhesive tape pressing plate 6 is provided with the registration holes that matches with bolt hole 2.
Described major and minor tooth plate is provided with anti-skidding line.
The technical problems to be solved in the utility model just provide a kind of can waterproof and dustproof, the stretching device of noiseproof, anti-skidding, anti-jump car.
Useful technique effect of the present utility model is:
On pre-buried anchor device, sleeve is set, after bolt passes tooth plate, is anchored in the sleeve that is arranged on the anchor device base plate, fastening with nut simultaneously through row, the hidden danger that can prevent in the stretching device use because of the initiation of problems such as nut loosening is set like this; U type waterproof adhesive tape fixes on the pre-embedded device with adhesive tape pressing plate and bolt anchoring, can well play harm such as preventing rainwater, dirt sand.This stretching device is simple in structure, and effect such as waterproof and dustproof, noise control, anti-skidding, anti-jump car is obvious, can be widely used in the different types of rridges.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Figure number: 1 connecting bolt; 2 bolts hole; 3 sleeves; 4 U type waterproof adhesive tapes; 5 main tooth plates; 6 adhesive tape pressing plates; 7 secondary tooth plates; 8 expansion bolts; 9 bridge deck pavements.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment: referring to Fig. 1, Fig. 2, the three-dimensional stretching device that is used for bridge construction, comprise main tooth plate 5, secondary tooth plate 7, pre-buried anchor device, connecting bolt 1, U type waterproof adhesive tape 4, adhesive tape pressing plate 6, adhesive tape pressing plate 6 usefulness stainless steel materials are made, and which is provided with the registration holes that matches with bolt hole 2.The pre-buried anchor device of stretching device is installed on the bottom surface of preformed groove with expansion bolt 8, and pre-buried anchor device is provided with sleeve 3, and sleeve 3 is provided with internal thread; Described main tooth plate 5 and secondary tooth plate 7 are provided with bolt hole 2, one end of described connecting bolt 1 is fixed on 3 li in the sleeve of pre-buried anchor device, the other end passes the registration holes of adhesive tape pressing plate 6 and the bolt hole 2 on the major and minor tooth plate, uses the nut anchoring again, is in the bolt hole 2 after the nut anchor is tight.
U type waterproof adhesive tape 4 both sides are fixed on the pre-buried anchor device with adhesive tape pressing plate 6.
Major and minor in addition tooth plate is provided with block anti-skidding line.
