Description

Edge Distance Checking Device for Bridge Bearing}

The present invention relates to a device for use in measuring the edge distance of a bridge bearing, and more particularly, it has a simple structure and enables accurate measurement of the edge distance, and can give portability as well as ease and convenience according to use. It relates to a bridge bearing edge distance measuring device.

In general, a bridge is constructed to include a bridge girder on which a vehicle or a person moves on an upper portion, an abutment or pier for supporting the bridge girder on the lower portion, and a support provided between the abutment or pier and the bridge girder.

That is, by providing the support, as well as the fixed load on the bridge girder side, as well as the moving load generated while the vehicle moves, the displacement in the direction of the bridge axis due to the change of temperature or the displacement and expansion due to impact such as wind power and seismic force. It functions to extend the life cycle of the bridge by accepting the displacement.

In this way, the support provided on the upper surface of the abutment or pier is constructed to secure an effective edge distance structurally for safety, and the support in the bridge axis direction to have the most efficient load resistance structure against the fixed and moving loads of the bridge girder. It is required to secure a certain number or more in the distance between the brigade and the podium of a shift or pier.

In addition, the edge distance of the bridge bearing represents the distance from the edge of the bearing to the edge of the lower part of the bridge (alternate or pier) when the bearing is made of steel, and an anchor to fix the bearing when the bearing is provided with an elastic body. It represents the distance from the center of the bolt to the edge of the lower part of the bridge (alternate or pier).

In addition, the edge distance of these bridge bearings is used in the safety diagnosis and inspection of the bridge.

In order to measure the edge distance of the bridge support, a method of measuring using a tape measure was used in the past, but there was a problem that a large measurement error occurred because it was necessary to read the scale that matches vertically at the edge of the lower part of the bridge by the naked eye. .

Incidentally, when the edge distance is as short as 10cm, the measurement error may be small, but there is a problem that the measurement error inevitably increases as the edge distance increases.

In particular, the method of using a tape measure in the related art has a problem of increasing the measurement error as the sag increases as the withdrawal distance of the steel band (tape measure) pulled out from the main body increases, and the operator holding the steel band (tape measure) pulled out from the main body There is a problem in that the accuracy of the measurement is degraded due to factors such as the case of shaking or movement of the hand.

Accordingly, in order to solve the conventional problems associated with measuring the edge distance of the bridge bearing, Korean Patent No. 10-1615962 (hereinafter referred to as'Patent Document 1') states that "the end of the support is vertically continuous with the support member. The right angle groove formed by the support member and the support is coupled and is seated at the edge of the pier, and the end of the measuring member is coupled to the upper end of the support member, and the support member is coupled to the end of the support and the measuring member through a rotational part. And the support member and the measuring member combined with the support member are folded in parallel with the support member, and the movable scale member is provided to slide in the measuring member so that the edge distance of the support can be measured at the rear end of the measuring member. Disclosed is a support edge distance measuring device for ".

However, Patent Document 1 has a problem in that the measurement accuracy may still be degraded, such as the position of the starting point may be changed when the operator's hand shaking or movement occurs due to poor fixation on the bridge support side, and the structure in which the ruler slides There are structural disadvantages such as unnecessarily lengthening the length, and there is a problem that inevitably causes inconvenience during handling and storage.

In addition, it is not suitable to measure the structurally accurate edge distance (the distance from the center of the anchor bolt of the bridge bearing to the edge of the lower part of the bridge (alternate or pier)), so it has a limitation in measuring the bearing edge distance.

In addition, in Korean Patent No. 10-1972767, a magnet holder adsorbed on the upper part of the bridge; Vertical guide pipe installed on the magnet holder; An upper lifting clamp having an upper vertical cutout hole and a dovetail groove; An upper lifting stop bolt fixing the upper lifting clamp to the vertical guide pipe; A micro-moving clamp having a dovetail protrusion coupled to the dovetail groove and having an upper horizontal incision hole; A fine adjustment mechanism for raising and lowering the fine moving clamp; An upper rotating rod inserted into the upper horizontal incision hole; An upper rotation stop bolt that stops the upper rotation rod; An upper laser holder having an upper reference surface; An upper laser distance measuring unit for detecting an upper measuring distance; A lower lift clamp having a lower vertical incision hole formed therein; A lower lift stop bolt fixing the lower lift clamp to the vertical guide pipe; A lower horizontal incision hole formed in the lower lifting clamp; A lower rotating rod inserted into the lower horizontal incision hole; A lower rotation stop bolt for stopping the rotation of the lower rotation rod; A lower laser holder having a lower reference surface; Disclosed is an edge distance measuring device for bridge safety diagnosis including a lower laser distance measuring unit that detects the lower measuring distance.

However, Patent Literature 2 has a configuration that measures the distance using a laser, which is structurally very complex and has difficulty in carrying and handling by an operator, as well as being large in length and volume, taking up a lot of space during storage. There is a problem.
