Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anchor system including a rotatable anchor system,

The present invention relates to a coordinate measuring apparatus, and more particularly, to an apparatus for measuring a position of an anchor socket installed on a bridge pier by arbitrarily changing the position of the anchor socket, And an anchor socket for supporting the anchor socket, and a maintenance type rotary anchor system capable of improving fixation force of the anchor socket and preventing bridge deformation from occurring.

Generally, bridges are influenced by dynamic loads and impact forces due to traffic, strong winds, earthquakes, etc., and also changes in temperature due to seasonal changes cause displacements such as elongation and contraction.

Accordingly, the Bridge Bearing Apparatus is installed to smoothly absorb the horizontal force and displacement of the bridge to smooth the seismic function of the bridge and increase the durability life.

The bridge is installed between the upper structure of the bridge and the structure of the bridge, so that all the load transferred from the bridge is transmitted to the bridge.

Such an apparatus is developed in various forms.

Generally known bridge devices consist of an upper plate coupled with the upper structure of the bridge, a lower plate fixed to the bridge, and a member slidably interposed between the upper and lower plates to absorb deformation and impact of the upper structure.

However, when such a coordinate system is fixed to a pier, it is mainly fixed by using an anchor socket. At this time, the pier is already completed, and since the bed portion provided for installing the coordinate system is reinforced Interference problems arise when installing anchor sockets. In other words, the bed part may be provided in advance when designing for the installation of a calibration device, and in some cases, a bed part may be provided by digging the upper surface of the pier to see the reinforcing bars, Since it is necessary to cure after being poured, a firm fixing force can be maintained, so that the reinforcing bars are inevitably exposed to the bed portion.

Furthermore, the anchor sockets are designed to allow at least 4.5 times the diameter of the concrete to penetrate into the concrete in order to prevent the fly-out failure when the concrete is poured and fixed to the pier (to prevent the concrete from falling off due to the leverage of the anchor subjected to shear) Therefore, the anchor socket must be inserted at a depth consistent with the regulations, whatever the case may be.

However, it is difficult to insert the anchor socket into the prescribed depth unless the reinforcing bars are placed in the bed portion of the pier, so as to avoid this.

For example, in order to maintain the depth of penetration of the anchor socket, it is necessary to artificially open or cut the interfering reinforcing bars in the pier. In this case, the load bearing capacity of the pier may be deformed, and the length of the anchor socket may be cut, Not only violates the regulations, but eventually destroys the issue of fire-out.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, an orthopedic device according to the present invention includes a universal structure, such as an upper plate 100 fixed to an upper structure of a bridge, and a lower plate 100 fixed on a bridge A lower plate 200 and an elastic body 300 interposed between the upper plate 100 and the lower plate 300 to absorb and buffer the relative flow of the upper structure of the bridge.

At this time, the elastic body 300 includes a rubber 310 having elasticity, and a reinforcing plate 320 disposed between the rubber 310 and equally spaced. Although not shown, a sliding member (not shown) is interposed between the elastic body 300 and the upper plate 100.

In this case, the sliding member is combined with the Teflon sheet and the stainless steel plate to absorb the horizontal deformation (horizontal displacement) of the upper plate fixed to the upper structure of the bridge by a sliding method, thereby preventing the elastic body 300 from causing shear deformation , The elastic body 300 absorbs and absorbs the vertical load.

Four anchor sockets 400 are assembled to the lower end of the lower plate 200. The anchor sockets 400 are placed on the bed part of the bridge pier and the concrete is placed thereon. And is fixed on the pier.

The structure of the above-described teaching apparatus adopts a known structure, and various kinds of teaching apparatuses as shown in Figs. 1B and 1C can be applied to the present invention. However, the present invention is not limited to the structure of the coarse apparatus itself, but is characterized by a special structure for installing an anchor socket to be described later. Therefore, the feature of the present invention will be described in detail below.

The structure for installing the anchor socket corresponding to the main feature of the present invention may have the following three embodiments.

[First Embodiment]

The structure for installing the anchor socket according to the first embodiment of the present invention is equally provided in the vicinity of the four corners of the lower plate 200 as shown in FIG.

Therefore, only one of these four will be exemplarily described.

Referring to FIG. 2, an annular protrusion 410 protrudes from an upper surface of the anchor socket 400.

The annular protrusion 410 has a predetermined depth of the bolt groove 412 formed therein.

A bolt hole 210 is vertically formed in the vicinity of the four corners of the lower plate 200 and an anchor bolt 220 is inserted into the bolt hole 210.

A rubber ring 420 is interposed between the anchor socket 400 and the lower plate 200 and a rubber washer 430 is inserted between the lower plate 200 and the head 222 of the anchor bolt 220. [ ).

Here, the rubber ring 420 is not a generally known simple ring, but a cylindrical member made of rubber material. Inside the rubber ring 420, the annular protrusion 410 is inserted therein, (422).
In addition, the anchor bolt 220 and the anchor socket 400 may be joined together to form a straight line, and the straight line may be installed so as not to be perpendicular to the lower plate 200.

2 (a), the annular protrusion 410 is inserted into the fitting hole 422, and then the upper portion of the annular protrusion 410 is formed in an empty state with a predetermined space S, Thereby inducing the rubber ring 420 to be more easily deformed when the socket 400 is opened.

The anchor bolt 220 is formed with a circular flange-shaped head portion 222 having a larger diameter than the bolt diameter. The rubber washer 430 has a bolt diameter corresponding to the anchor bolt 220 And the outer diameter of the rubber washer 430 is formed to be equal to or larger than that of the head portion 222 so that when the anchor bolt 220 is fastened, the head portion 222 can be tightened .

The bolt hole 210 formed in the lower plate 200 is formed to be larger than the bolt diameter of the anchor bolt 220 so that the bolt hole 210 can be inclined. It is possible to induce the deformation more smoothly together with the rubber ring 420.

Particularly, the reason for forming the annular protrusion 410 to be fitted in the rubber ring 420 on the upper surface of the anchor socket 400 is to maintain a stable fixed relationship by increasing the adhesion force.

In addition, although the rubber ring 420 may be of various sizes, it is preferable to use a rubber ring having a height of 10-40 mm and a diameter of 20-150 mm. If the height is less than 10 mm, the height is too low, It is preferable that the height is limited to the above range because it is difficult to design the rebar avoiding design because the angle is small and if it exceeds 40 mm, the amount of the load is increased due to the applied load and the leveling is very difficult.

In the case of the diameter, too, the diameter is less than 20 mm, which is too small to be bent, and when it exceeds 150 mm, the diameter becomes too wide and the angle at which it can be bent becomes small.

The working relationship for the construction of the teaching apparatus according to the present invention having such a configuration is as follows.

2 (a), when the reinforcing bars T and the anchor sockets 400 are not interfered with each other, the anchor sockets 400 may be vertically positioned as they are without being bent.

At this time, in order to maintain the height of the calibration apparatus, it is necessary to appropriately adjust the installation height by using a computer bolt (not shown), to form a mold around the upper surface of the pier, to fill and fill the concrete mortar, It is possible to accurately and quickly construct the teaching apparatus according to the present invention.

The anchor bolts 220 are inserted into the bolt holes 210 from the upper portion to the lower portion of the lower plate 200 under the interposition of the rubber ring 420 and the rubber washer 430, It is needless to say that the lower end is fixed to the bolt groove 412 provided on the annular protrusion 410 of the anchor socket 400 to fix the anchor socket 400.

2 (b), when the reinforcing bars T laid on the bed portion of the bridge pier and the anchor socket 400 to be installed overlap each other, the anchor socket 400 is slightly pulled outward It opens.

The space S is formed between the upper end of the annular protrusion 410 and the fitting hole 422 formed in the rubber ring 420. The anchor bolt 220 is fixed to the upper end of the anchor socket 400, The rubber ring 420 can be easily deformed so that the anchor socket 400 can be opened. As a result, the reinforcing bar T can be arranged to be dislocated, thereby eliminating the difficulty of installation due to interference.

In this way, when the placement of the reinforcing bars T is completed, the process of forming the formwork, pouring the concrete, and curing are performed in the same manner.

As described above, since the anchor socket 400 can be easily installed by avoiding the reinforcing bars T on the bed portion of the piers without deteriorating the fastening force, The anchor socket 400 is advantageous in that the structure for avoiding the rebar (T) of the anchor socket 400 is simple and simple, and the manufacturing cost is low. .

In addition, according to the present invention, unlike the conventional method, the maintenance facility is convenient. For example, when the calibration device is damaged or replaced due to other reasons, a hydraulic jack is installed between the bridge and the bridge The concrete mortar penetrates into the gap between the anchor bolt and the lower plate and is cured in a completely fixed state, so it is very difficult and difficult to unlock the anchor bolt. However, in the structure according to the present invention, since the rubber washer acts as a sealing material between the head portion and the lower plate of the anchor bolt, the concrete mortar can not penetrate into the gap, so there is almost no anchored bolt.

Therefore, it is advantageous in that the convenience of maintenance can be remarkably improved because the anchor bolt is removed from the jacked up state during the maintenance work for replacement, and then the shaft device itself is slightly lifted and then pushed to the side. This can be similarly applied to the other embodiments described below.

[Second Embodiment]

3, the anchor socket 220 including the anchor bolts 220, the rubber washers 430, the rubber rings 420, and the anchor sockets 400 are formed in the same manner as in the first embodiment But the structure of the anchor socket 400 is slightly deformed to further simplify the structure.

That is, the upper end of the anchor socket 400 is flat, and the bolt groove 412 is directly formed at the center of the upper surface so that the lower end surface of the rubber ring 420 and the upper end surface of the anchor socket 400 are in surface contact Respectively.

Therefore, in this case also, when the reinforcing bars T (see FIG. 2) are to be avoided, if the anchor sockets 400 are opened, the rubber rings 420 are deformed and interference with the reinforcing bars T can be avoided. .

In the third embodiment as well as the first embodiment described above, when the bolt holes 210 formed in the lower plate 200 are viewed in the depth direction, when the vertical cross-section of the bolt hole 210 is formed to have an inverted trapezoidal shape, So that the anchor socket 400 can be more smoothly opened when the anchor socket 400 is opened.

In addition, the construction method is the same as the first embodiment described above.

[Third Embodiment]

4, the anchor socket 400 including the anchor bolts 220, the rubber washers 430, the rubber rings 420, and the anchor socket 400 are formed in the same manner as in the second embodiment But the structure of the rubber ring 420 is slightly deformed to further suppress the shaking of the anchor socket 400.

That is, the anchor socket 400 is formed by directly forming a bolt groove 412 at the top and the top of the flat top in the same manner as in the second embodiment.

On the other hand, the rubber ring 420 is formed in a lower part of the fitting hole 422 in which the anchor bolt 220 is inserted, a socket groove 422 which is larger than the fitting hole 422 and in which a part of the upper end of the anchor socket 400 can be fitted. (424) are further formed.

Therefore, the diameter of the rubber ring 420 should be larger than the diameter of the anchor socket 400.

Particularly, it is preferable to form a gap of 10-20 mm between the inner diameter of the socket groove 424 and the outer diameter of the rubber ring 420 in order to induce smooth bending.

Since the anchor bolt 220 is fastened to the bolt groove 412 of the anchor socket 400 in a state where a part of the upper end of the anchor socket 400 is inserted into the rubber ring 420, And the fluidity, that is, the shaking is minimized.

Therefore, in this case also, when the reinforcing bars T (see FIG. 2) are to be avoided, if the anchor sockets 400 are opened, the rubber rings 420 are deformed and interference with the reinforcing bars T can be avoided. .

In addition, the construction method is the same as the first embodiment described above.
