Description
Technical Field
The utility model belongs to the technical field of the construction technology and specifically relates to a bridge expansion joint anchor district concrete crack repair structure is related to.
Background
Bridge expansion joints: it is referred to that in order to meet the requirement of deck deformation, expansion joints are usually provided between two beam ends, between a beam end and an abutment, or at the hinge joint of a bridge.
The bridge expansion joint is arranged at the weak part of the two end structures and is exposed in the nature for a long time, so that the environment is severe. With the increase of traffic volume and the increase of automobile load capacity, the repeated impact action of wheel load is directly born, and the abrasion and fatigue of materials can often occur, so that the bridge structure is easy to damage and the position which is difficult to repair is easy to be damaged when the concrete is anchored in the bridge expansion joint.
Therefore, it is desirable to provide a concrete crack repair structure for an anchoring area of a bridge expansion joint to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an easily construct, restoreed bridge expansion joint anchor district concrete crack restoration structure.
The technical scheme of the utility model is that: the concrete crack repairing structure comprises a repairing groove, a grouting material layer and a supporting piece, wherein the grouting material layer extends downwards from the repairing groove, the supporting piece is clamped in the repairing groove and is arranged along the length direction of the repairing groove, the supporting piece comprises a connecting part and a butting part, the connecting part is horizontally arranged, the butting part extends towards the same side along two ends of the connecting part, the butting part is matched with the side wall of the repairing groove, and a plurality of through pouring holes are formed in the butting part; a repairing glue layer is arranged above the supporting piece; the repair groove is of a trapezoidal structure with an upper opening larger than a lower opening.
Preferably, the support member is made of a rubber material.
Preferably, the connection portion and the abutting portion are connected by an arc chamfer.
Preferably, the connecting portion of the support member has a hardness greater than that of the abutting portion.
Preferably, the support member is disposed adjacent to a lower end of the repair groove.
Preferably, a polymer adhesive layer is coated between the abutting part and the side wall of the repair groove.
Preferably, the repair glue layer is an RT-4 repair filling material layer.
Compared with the prior art, the beneficial effects of the utility model are that: the supporting pieces are used for supporting the damaged concrete blocks in the repairing grooves, and then the grouting material layer is poured, so that the blocks can be healed. Meanwhile, the supporting piece has a better sealing effect; the RT-4 rapid repairing material is adopted, so that the rapid setting is high and strong, and the later strength is not shrunk; non-shrinkage, micro-expansion and adhesive properties; the traffic can be opened in a short time (2-4 hours), the construction process is simple, and the traffic passage is not influenced.
Drawings
Fig. 1 is the utility model provides a cross section structure sketch map of bridge expansion joint anchor district concrete crack repair structure.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" used herein refer to the directions of the drawings, and do not limit the structure of the drawings.
As shown in fig. 1, the utility model provides a structure is restoreed to bridge expansion joint anchor district concrete crack includes restoration groove 1, certainly 1 downwardly extending's in restoration groove grout material layer 2, the card is located in restoration groove 1, along the support piece 3 that 1 length direction in restoration groove set up.
And (4) mechanically chiseling the crack positions into a trapezoidal structure with an upper opening larger than a lower opening.
The support piece 3 comprises a connecting part 31 arranged horizontally and an abutting part 32 arranged along two ends of the connecting part 31 in an extending mode towards the same side, the abutting part 32 is matched with the side wall of the repairing groove 1, and a plurality of through pouring holes 33 are formed in the abutting part 32.
The supporting piece 3 is installed in the repairing groove 1, and polymer adhesive 4 is coated between the abutting part and the side wall of the repairing groove, so that the abutting part and the repairing groove are glued and sealed. Grouting material is poured along the pouring hole 33.
The supporting member 3 is made of rubber material, and has good elasticity. The connecting part 31 and the abutting part 32 are provided with arc chamfers in a switching way, so that stress concentration can be reduced. In the strut member 3, the hardness of the connecting portion 31 is greater than that of the abutting portion without forming the casting hole 33, the casting hole 33 is formed in the connecting portion 31, and after the grouting is completed, the casting hole 33 is closed to provide a certain rigidity to the connecting portion 31. The support piece 3 is arranged close to the lower end of the repair groove 1, more space is provided for the repair glue layer 5 arranged above the support to fill up the repair material, the repair requirement is met, and the service life is prolonged.
The repair glue layer 5 is an RT-4 repair filling material layer, so that the repair material is not shrunk or slightly expanded, has strong bonding capability with the original concrete, has excellent durability and fatigue load resistance, can be normally constructed at the ambient temperature of more than 5 ℃, and can meet the requirement of traffic opening within 4 hours.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
