Description

Anti-seismic upper connectors for external wall hanging panels

technical field

The utility model relates to a connecting piece for a hanging board on an outer wall of a building, in particular to an anti-seismic upper connecting piece for a hanging board on an outer wall.

Background technique

With the continuous improvement of the industrialization technology level of the construction industry, more and more prefabricated buildings are being promoted and applied. Beam connection, the structure of the existing external wall hanging board connectors is mostly embedded in the external wall hanging board, and the hook is installed on the frame beam. When installing, the hook is hooked to the cross bar to realize the external wall hanging board. Fixed installation. The current connection method of external wall hanging boards has little room for adjustment during installation, and has high requirements for the position accuracy of embedded parts during construction, making production and assembly difficult, which affects the production and construction progress. Moreover, the existing connecting piece between the external wall hanging board and the frame beam is a rigid connection, and a slight relative displacement occurs between the frame beam and the external wall hanging board when the temperature changes or the earthquake is encountered in the later use of the building. The displacement will cause damage to the connection nodes between the frame beam and the external wall siding, causing the building's external wall to fall off; the existing external wall siding cannot be adjusted after installation, and it is difficult to ensure uniform joints between adjacent external wall sidings. Affects the regularity of the appearance of the building.

Utility model content

The purpose of the utility model is to provide an anti-seismic upper connector of an external wall hanging board, which can solve the problems existing in the prior art.

In order to achieve the above object, the utility model is realized through the following technical solutions: comprising a horizontal plate, one end of the horizontal plate is provided with a horizontal strip hole, the length direction of the horizontal strip hole is parallel to the width direction of the horizontal plate, and bolts are installed in the horizontal strip hole, The bolts are connected with the screw holes on the pre-embedded connectors through threads. The embedded connector includes a flat plate, on which a through hole is opened, a nut is installed on one side of the through hole, the screw hole of the nut is connected with a bolt through a thread, and an embedded pile is arranged on one side of the flat plate where the nut is installed. The bolts pass through the screw holes of the pre-embedded connectors, and fastening nuts are installed at the ends of the bolts. A spacer is installed between the head of the bolt and the cross plate. A pre-embedded body is provided at the end of the horizontal plate away from the transverse strip hole, and the pre-embedded body and the pre-embedded connector are located on the same side of the horizontal plate.

The utility model has the advantages that: the installation position between the frame beam and the outer wall can be adjusted, which reduces the requirement for the accuracy of the embedded parts during construction, and at the same time reduces the difficulty of production and assembly, which is conducive to improving production and construction efficiency. When there is a relative displacement between the external wall hanging board, the connecting piece itself can move within a certain range to avoid damage to the connecting piece.

detailed description

The anti-seismic upper connector of the external wall hanging panel described in the utility model comprises a horizontal plate 1, and one end of the horizontal plate 1 is provided with a horizontal strip hole 2, and the length direction of the horizontal strip hole 2 is parallel to the width direction of the horizontal plate 1, and the horizontal strip shape A bolt 3 is installed in the hole 2, and the bolt 3 is connected with the screw hole on the pre-embedded connector through threads. When making the external wall hanging panels, two sets of pre-embedded connectors are pre-embedded on the top of the external wall hanging panels. Before the external wall hanging panels are installed, the two sets of horizontal plates 1 are fixed and installed on the frame beams at the positions corresponding to the embedded connectors. , when installing the external wall hanging board, connect the bolt 3 from the top of the horizontal plate 1 through the horizontal strip hole 2 and then connect it with the screw hole on the corresponding embedded connector, and the bolt 3 can move laterally within the range of the horizontal strip hole 2 , so the position of the external wall hanging panels can be fine-tuned after installation to ensure that the joints between the external wall hanging panels are neat. A gap larger than the thickness of the horizontal plate 1 can be reserved between the head of the bolt 3 and the embedded connector. When the building encounters temperature changes or earthquakes in the later stage of use, the relative displacement between the frame beam and the external wall hanging plate will occur. When the displacement occurs, the bolt 3 can move horizontally or vertically in the horizontal strip hole 2 to offset the force generated by the displacement on the connecting piece itself, so as to ensure that the connecting piece will not be damaged.

The pre-embedded connector of the utility model can adopt various structures, for example, a pre-embedded sleeve with threads can be used, and the preferred structure is: the pre-embedded connector includes a flat plate 4, and a through hole is opened on the flat plate 4 5. A nut 6 is installed on one side of the through hole 5, and the screw hole of the nut 6 is connected with the bolt 3 through threads, and a pre-embedded pile 7 is installed on the side of the plate 4 where the nut 6 is installed. When pre-embedded, the flat plate 4 can be flush with the top surface of the external wall siding, which can protect the nut 6 and the internal thread, prevent the external wall siding from colliding and damaging the connecting parts during transportation, and at the same time prevent the concrete around the connecting parts Cracking occurs. The pre-embedded pile 7 of the utility model can adopt various forms, such as a screw rod, a crotch, a cylinder with a convex ring or a concave pattern, and the like.

In the utility model, in order to increase the contact area between the bolt 3 and the transverse plate 1, a gasket 9 can be installed between the head of the bolt 3 and the transverse plate 1.

The utility model can be used for the connection between the concrete frame beam or the steel structure frame beam and the hanging board of the external wall. When the frame beam is a steel structure, the horizontal plate 1 can be connected with the frame beam by means of welding, riveting or bolt connection; when the frame When the beam is a concrete structure, the embedded body 10 can be arranged at the end of the horizontal plate 1 away from the horizontal strip hole 2. The embedded body 10 and the embedded connector are located on the same side of the horizontal plate 1. When making a concrete frame beam, the horizontal The pre-embedded body 10 of the plate 1 is pre-embedded into the frame beam to realize the connection between the horizontal plate 1 and the frame beam.
