Shown in Fig. 2 to Fig. 5 is the construction process figure of bridge expanssion joint construction of the present invention.
Embodiment
Below with reference to the accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention
And discussion, it is clear that as described herein is only a part of example of the present invention, is not whole examples, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example, belongs to protection scope of the present invention.
For the ease of the understanding to the embodiment of the present invention, make further by taking specific embodiment as an example below in conjunction with accompanying drawing
Illustrate, and each embodiment does not constitute the restriction to the embodiment of the present invention.
As shown in figure 1, the bridge expanssion joint construction that the present invention is provided, including expansion joint substrate material and expansion joint sealing
Agent material, replaces existing type steel expansion joint.
Expansion joint substrate material includes fast hardening concrete basic unit 1 and elastic polyurethane concrete topping 2.Fast hardening concrete
Basic unit 1 is cast in the both sides of the reserved notch at expansion joint, and the section of the fast hardening concrete basic unit 1 of both sides has " recessed " shape structure；
Elastic polyurethane concrete topping 2 is cast in fast hardening concrete basic unit 1, the elastic polyurethane concrete topping 2 of both sides it is disconnected
Face has " convex " shape structure, and the fast hardening concrete basic unit 1 with both sides is connected respectively.By convex configuration form increase with
The build-in force and frictional force of fast hardening concrete basic unit 1, without setting reinforcing bar to be anchored.
Fast hardening concrete basic unit 1 possesses the characteristics such as big rigidity, early epistasis, easy mix, and the presetting period is short, and strength enhancing is fast,
It is applied to undertake the load that surface layer is transmitted with rigidity, and the characteristic of early epistasis and easy mix is beneficial to rapid construction, is made such flexible
Seam is applied to the replacing at existing disease expansion joint, repairing construction.Elastic polyurethane concrete topping 2 is by good elasticity absorption
The impulsive force of vehicle, stress form is better than the rigid collision of concrete topping, in the range of its bearing capacity, increases substantially flexible
Stitch service life.
Expansion joint sealant material includes sealant bed die 4 and sealant 3.Sealant bed die 4 be arranged on expansion joint it
Between, sealant 3 can inject expansion joint on this basis, so as to be sealed to expansion joint, sealant 3 uses polyurethane material
Constitute, with great rate elongation, caking property and water proofing property, to replace the watertight rubber band of existing type steel expansion joint, resistance completely
Only in road surface current immersion expansion joint.
As shown in Figures 2 to 5, the manufacturing step of bridge expanssion joint of the invention construction is as follows：
（1）The reserved notch dimensional depth 15-20cm, width 15cm at expansion joint（Or existing expansion joint disease notch coagulation
Soil is cut）, dust, chip are then removed, side form cystosepiment is installed（It is easy to disassemble）；
（2）In the intraoral surface smear interfacial agents of preformed groove, fast hardening concrete underlayment 1 is then poured, and by pressing mold, make
The section of fast hardening concrete underlayment 1 is in " recessed " shape, " recessed " shape mouthful dimensional depth 7cm, width 10cm, 3 × 3cm of sagging recess；
（3）Fast hardening concrete underlayment 1 is pre-hardening after 2 hours（Depending on presetting period is according to actual conditions, simply lift herein
Example explanation）, pressing mold is taken out, treats that surface no moisture is excessive, is used to increase poly- in the external coating silane coupling agent of fast hardening concrete underlayment 1
Cohesive force between urethane elastic concrete surface layer 2 and fast hardening concrete underlayment 1, silane coupling agent finger touches slightly dry after-pouring polyurethane bullet
Property concrete topping 2；
（4）After the completion of elastic polyurethane concrete topping 2 is prepared according to two-component, appropriate aggregate is mixed（Grain can be used
Footpath is not more than 1cm hair side cobblestone）, after-pouring is stirred on fast hardening concrete underlayment 1, passes through mix goose ovum
The modulus of elasticity of elastic polyurethane concrete topping 2 formed after stone, solidification is small, possesses preferable elasticity, can effectively absorb wheel punching
Energy is hit, is hardly damaged；
（5）Side form cystosepiment is removed after the initial set of elastic polyurethane concrete topping 2, sealant bed die is filled in expansion joint
4（Foam rods are used to be not limited thereto as sealant bed die, but the present invention in the present embodiment）, inject close into expansion joint
Agent 3 is sealed, injection depth is the 1/2 of expansion joint width, and the top surface of sealant 3 is slightly below the top of elastic polyurethane concrete topping 2
Face；
（6）Can open to traffic after pouring completion 1 hour to elastic polyurethane concrete topping 2（This is stretched for shaped steel
Contracting seam replaces maintenance construction）.
Compared to prior art, advantage of the invention is that：
1st, constructing operation is simple, rapid, you can applied to newly building bridge engineering, it can also be used to which existing disease expansion joint is replaced
Generation and maintenance, can reach the effect of short time open to traffic in the Renewal process of existing disease expansion joint；
2nd, anti-fatigue performance, endurance quality, corrosion resistance are good, normal service life 10 years or shock resistance 2,000,000 times；
3rd, sealant has 100% rate elongation, is applicable to below 8cm all width-telescopics seam.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
It should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
It is defined.
