Description
The present invention can minimize the inflow of rainwater or various foreign substances to reduce the maintenance cost due to corrosion or damage of the structure, easy construction and extend the life of the structure, so only damaged parts need to be replaced during repair In addition to reducing costs, the present invention relates to an expansion joint that can be stably integrated with a structure by increasing the contact area with the structure.
In general, structures such as bridges are subjected to deformation stresses caused by various causes such as temperature changes, creep and shrinkage, construction errors, loading loads, earthquakes and ground subsidence.
If the stress is constrained without being released, there is a risk of cracking and damage to the structure. Therefore, when the structure is constructed, there is a joint gap, which is a gap that is spaced at regular intervals, and there is a separate expansion joint in the joint gap. The device is installed to close the joint gap while smoothly accommodating the dynamic behavior of the structure.
For example, when the structure is a bridge, the bridge is composed of a plurality of bridges at the bottom and a plurality of tops that are seated on the top of the bridges to form a road, and the top plate and the top plate is connected to the top plate and smoothly the dynamic behavior of both tops. The gaps are provided with appropriate clearance widths to accommodate them.
In addition, by connecting and closing the joint gap in a horizontal direction so that the vehicle running on the upper side can run smoothly, rainwater or various foreign substances flow into and fall through the joint gap to contaminate or corrode the lower facilities of the bridge. Flexible expansion joints are installed in the gaps of the joints to prevent them.
Expansion joints have a direct impact on the safety and durability of the structure, and because of the highest damage and replacement frequency in the overall structure of the structure, it should basically be able to provide a complete and durable function of expansion and sealing. It should be excellent in resistance to ultraviolet rays or various chemicals when exposed to the outside, and it should be possible to reduce the traffic control when repairing.
Expansion joints are mainly divided into rubber type and steel type, and most of them are provided with anchor bolts integrally and fixed to the structures on both sides of the joint gap through the anchor bolts, and weld the anchor bolts to each of the rebars planted in the structure. In addition, the non-shrinkage or general concrete is poured to cure the anchor bolt to cure it, so that it is firmly fixed. However, the process of welding the anchor bolt and curing the concrete one by one requires a lot of labor and time. there was.
An object of the present invention is to provide an expansion joint device that can reduce the maintenance costs due to corrosion or damage of the structure by minimizing the inflow of rainwater or various foreign matters.
Another object of the present invention is to provide an expansion joint device that can reduce the cost because the construction is simple and can extend the life of the structure, and only replace damaged parts during repair.
Another object of the present invention is to provide an expansion joint device which can be stably integrated with a structure by increasing the contact area with the structure.
The expansion joint device installed in the joint gap of the structure according to the present invention, the support is formed to be spaced apart from each other to face each other, the support wing is formed to protrude to the lower side of the support fixed to the structure, connecting the connection between the support Support means formed to bend toward the upper direction; Is coupled to the support is supported, both sides are open so as to communicate, the upper surface and the lower surface is formed to be bent toward the lower direction, the expansion and contraction means of the hollow shape formed at least one coupling groove on one side of the outer surface; And an angle coupled to the coupling groove to be placed on the expansion means, and closing the gap. This includes.
Preferably, the outer surface of the support wing, characterized in that one or more first projections are formed in a direction perpendicular to the direction of the support wing.
Preferably, the outer surface of the expansion means is projected in the direction of the structure, characterized in that it comprises two or more coupling wings that are coupled to the structure to secure the expansion means to the structure.
Preferably, the outer surface of the coupling blade, characterized in that one or more second projections are formed in a direction perpendicular to the direction of the projection of the coupling blade.
The expansion joint device of the present invention has an advantage of reducing the maintenance cost due to corrosion or damage of the structure by minimizing the inflow of rainwater or various foreign matters.
In addition, the construction is easy and can extend the life of the structure, there is an advantage that can be reduced because only the damaged parts need to be replaced during repair.
In addition, there is an advantage that can be stably integrated with the structure by increasing the contact area with the structure.
Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
1 is an exploded view of the expansion joint according to an embodiment of the present invention, Figure 2 is an assembly view of the expansion joint according to an embodiment of the present invention.
As shown, the expansion joint according to an embodiment of the present invention is largely configured to include the support means 10, the expansion means 20 and the
The support means 10 is disposed below the
At this time, the
Stretching means 20 is formed in a hollow shape, both sides are open to communicate with each other, the upper surface and the lower surface is bent toward the lower direction, that is formed in a U shape. In addition, at least one
Thus, the expansion means 20 formed in a hollow U shape can be flexibly stretched and can be preferably applied to other structures besides tunnels or underground roadways. Of course, the upper and lower surfaces may be formed in a flat shape, but in this case, the upper surface flatness may be applied to a sidewalk bridge, a stadium, and the like, which should be considered more important.
On the other hand, like the
3 is an installation state diagram of the expansion joint according to an embodiment of the present invention. Here, the expansion joint according to an embodiment of the present invention can be used in various structures, hereinafter will be described by taking an example that is applied to the gap of the bridge.
As shown in FIG. 3, the expansion joint according to an embodiment of the present invention is constructed in a
The
A bolt B, for example, a start bolt is connected to the reinforcing
In the case of the
Such breakage is often caused by rain or foreign matter, such as air introduced into the gap where the expansion joint is installed.
Therefore, the
In addition, even when repairing due to the damage of the
It is to be understood that the present invention is not limited to the above-described preferred embodiments but may be practiced in various ways without departing from the spirit of the present invention. If you grow up, you can easily understand. If the implementation by such improvement, change, replacement or addition falls within the scope of the appended claims below, the technical idea is also regarded as belonging to the present invention.
