PRECAST PANEL TO PANEL CONECTIONS USING TEMPORARY PLATE    

INTRODUCTION :

To explain the application and detailing requirements of temporary loose plate connections used in precast panel-to-panel joints. This document outlines the types of connections (parallel and corner), their structural purpose during erection, and their specific use in warehouse and multistorey buildings. It also highlights the importance of accurate detailing for cast-in ferrules and placement considerations to avoid clashes with structural elements like roof steel.

The plate connection used in Precast Panel to Panel connection depends on weight, wind, loading, and shape. The plate also contributes to the additional strength of the panels.

These connections are used after erection, as they are already structural connections at the panel bottom (grout tube with dowel bars), along with the brace connection. After that, an additional temporary plate is connected from panel to panel for extra strength.

THE LOOSE PLATE TYPE OF CONNECTION:

1. Panel to panel (Parallel).
2. Perpendicular panel with corner connection.

This type of connection is commonly used for panel-to-panel connections.

1.PANEL TO PANEL (PARALLEL):

2.PERPENDICULAR PANEL TO PANEL CONNECTIONS AT CORNER JOINT

APPLICATIONS:

WAREHOUSE BUILDING CONDITION.

The panel-to-panel connection adds additional strength and also helps with propping.

The loose plate connects to the panel surface with the help of cast-in ferrules.

This type of connection is mostly used in warehouse projects, and the plate is usually not removed after erection.

The detailer should provide exact locations with dimensions for cast-in ferrules. For example, refer to the drawing below.

This type of connection is placed inside the building to avoid affecting the exterior appearance.

MULTISTORE BUILDING.

Basically, precast panel-to-panel connections involve steel loose plate connections to support the erection process. Mostly, this type of plate connection is temporary.

Once the precast wall is erected, the loose plate is connected to the cast-in ferrules with the support of propping.

Once panel erection is completed, the loose plate will be removed. The main reason for removing the plate is to achieve the panel finish.

This type of connection is placed inside the building to avoid affecting the exterior appearance.

NOTES:

    Generally, position all precast connections below the roof steel to avoid clashes with any roof steel works. When placed above the roof steel, they may interfere with the installation or alignment of roof components.
