Description

Building piping earthquake-proof support structure

The present invention relates to a building piping seismic design support structure, and more particularly to a new building piping seismic design support structure that can achieve a seismic design of a building by a simplified structure.

In many cases, new buildings (new buildings) are constructed in a horizontal direction in succession to existing buildings. In the case of new buildings, they are designed and constructed to have sufficient resistance to earthquake loads in accordance with the reinforced standards from the time of construction.

The current passive system of rescue systems is designed to perform its intended function under external influences (load and environmental influences) considered at the design stage. Therefore, if a large safety factor is not taken into account to reflect the uncertainty of external factors, there is a limit that it cannot function under an unexpected load at the design stage and may cause social loss.

In addition, the seismic elements designed according to the current seismic design concept must be dissipated in the structure as plastic deformation after the yielding of the flexural reinforcement, even under the seismic load of the size reflected in the design stage. Therefore, even after the earthquake within the design load damage to the structure is inevitable, there is a problem that requires a lot of restoration cost for the reuse of the structure after the earthquake.

By moving the connecting bracket 42 on the basis of the first end of the support bar 20, the support bar is aligned with the angle of the pipe 2 installed in the direction parallel to the beam 4 of the building. Since it can be coupled to the first end of the (20), even if the pipe (2) is installed in a direction parallel to the beam (4) installed in the building can be coupled to the annular hanger body (10) without restriction to the pipe (2). It is. By turning the hanger body 10 and the connecting bracket 42 which consists of a pair of hanger body pieces 110 on the basis of the support bar 20, a pair of hanger body pieces 110 are raised to raise the beams 4 and Even when the pipe 2 is installed in a side-by-side direction, the pair of hanger body pieces 110 of the hanger body 10 may be fitted to the outer peripheral surface of the pipe 4 to be coupled.

In addition, in another embodiment of the present invention, when the connecting bracket 42 coupled to the first end of the support bar 20 is released from the first end, the annular hanger body 10 may also be easily supported. It can be easily removed from the first end.

Meanwhile, in another embodiment of the present invention, other effects other than the above-described effects are the same as those described in the above-described embodiment of the present invention, and thus redundant description thereof will be omitted.

Meanwhile, in the present invention, the connecting bracket 42 includes an insert connecting bracket piece 42IP and an outer connecting bracket piece 42OP, and a bar insert between the insert connecting bracket piece 42IP and the outer connecting bracket piece 42OP. The groove 42BIG is provided, the inner surface of the insert connecting bracket piece 42IP is disposed to face the inner surface of the outer connecting bracket piece 42OP, and the inner surface of the insert connecting bracket piece 42IP is disposed on the inner surface of the insert connecting bracket piece 42IP. Auxiliary support groove 42SUG is provided.

In addition, a tapered bolt portion BTT is provided at the front end portion of the bolt BT (that is, the end portion opposite to the head portion).

In addition, the support bar 20 is further provided with a bolt through hole 20H penetrated to the inner and outer peripheral surfaces.

Accordingly, the support bar 20 is supported by the bolt BT in the state where the support bar 20 is inserted into the bar insert groove secured between the insert connecting bracket piece 42IP and the outer connecting bracket piece 42OP of the connecting bracket 42. Since it is coupled to the bolt through hole (20H) of the (20), there is an effect that the support force to hold the bolt (BT) to connect the support bar 20 to the connection bracket 42 is higher. This is because the bolt BT is inserted into the bolt through hole 20H of the support bar 20 to support the support bar 20 to prevent it from being separated from the connection bracket 42OP.

In addition, since the lower portion of the bolt BT and the tapered bolt portion BTT further enter the auxiliary support groove 42SUG formed in the insert connecting bracket piece 42IP of the connecting bracket 42, the bolt is pressed closely. Since the BT is prevented from being easily released from the connection fixing piece 4CP by external factors (for example, vibration, etc.), the bolt BT connects the support bar 20 to the connection bracket 42. There is an effect that improves the holding capacity as much as possible.
