Technical Field

The invention belongs to a deformation monitoring method for a support system of a concrete pouring template for building construction, and particularly relates to a deformation monitoring method for a support system of a concrete pouring template for building construction.

Background

The formwork support system may have a certain settlement and displacement due to pressure in the concrete pouring process and a period of time after the concrete pouring, and a collapse accident may occur if the change is too large. In order to reflect the change condition of the high formwork supporting system in time and prevent accidents, the supporting system is required to be subjected to settlement and displacement monitoring.

Disclosure of Invention

The invention aims to provide a deformation monitoring method for a concrete pouring template support system in building construction, which has the advantages of reasonable structure, simple manufacturing process, strong reliability and reusability, does not need personnel to enter the lower part of a template support system frame body for monitoring the deformation of the support system, can realize unmanned detection and improves the safety.

The purpose of the invention is realized as follows: a deformation monitoring method for a concrete pouring template supporting system in building construction comprises the steps of pouring concrete into a template structure supported by the supporting system, fixedly connecting a force transmission rod piece on the supporting system, fixedly connecting a monitoring device on the lower portion of the force transmission rod piece, connecting the monitoring device to a power circuit, mounting a bulb on the power circuit, transmitting a load to the monitoring device through the force transmission rod piece when the template supporting system is loaded, automatically cutting off a power supply through a contact piece of the monitoring device when deformation displacement of the force transmission rod piece exceeds an early warning set value, and extinguishing and alarming the bulb.

The invention is composed of a power supply loop, a force transmission rod connected with a support, a monitoring device, a lamp holder bulb, a fixed mount and a power supply lead.

1. A power supply circuit: a common power supply loop for supplying power by using a common power supply lead has the voltage of 220V.

2. Force transmission rod piece: and the force transmission rod piece is fixed on the template supporting system (steel pipe bracket) and used for monitoring the deformation of the template supporting system. When the template supporting system is loaded, the loaded load is transferred to the monitoring device at the lower part through the force transfer rod piece, and when the deformation exceeds a set value, the monitoring device can automatically cut off the power supply, so that the bulb is turned off. The deformation early warning set value of the force transmission rod piece is 10mm-15 mm.

3. A monitoring device: the monitoring devices are externally provided with protective shells (made of insulating materials, and if the protective shells are made of insulating tapes, the protective shells are wound to avoid hurting people), and are internally provided with two copper contact pieces (detached from the waste sockets) arranged in parallel. The tail end of the contact piece is connected with a power supply and is fixed on the protective shell, and the front end of the contact piece is in lap joint with a power supply lead at the other end of the loop (can be simply fixed by a rubber band). Because the template support is connected into a whole through the fastener, when the support body is deformed (unstability and settlement), the force transmission rod piece is driven to generate displacement downwards or towards the front, back, left and right directions, the lapping length of the front end of the contact piece and the power supply lead at the other end is 10mm, the total stretching length of the force transmission rod piece and the power supply lead fixed on the fixing frame is not more than 5mm, when the displacement reaches 10mm, the front end of the contact piece of the monitoring device is gradually separated from the power supply lead lapped at the fixed end, and the loop is disconnected.

Lamp holder bulb: a common bulb base connected to the loop.

Fixing a frame: the support of fixed lamp holder bulb, the bottom is fixed.
