Description

Bidirectional anti-seismic support for air duct

Technical Field

The utility model relates to the field of air pipe installation, in particular to a bidirectional anti-seismic support for an air pipe.

Background

Along with the continuous improvement of the building safety requirement, facilities such as water, heating, electricity, fire control and the like of the building need anti-seismic design so as to ensure that secondary damage is avoided when the facilities are damaged by earthquake. Avoiding casualty of personnel and reducing economic loss. The ductwork of existing air conditioning systems is typically suspended from the ceiling using a pair of vertical hangers. When external disturbance occurs, the air duct is prone to swing, and then falls off, or the air duct is disconnected due to swing in all directions.

Disclosure of Invention

In order to enhance the stability and the shock resistance of the air duct installation, the utility model aims to provide a bidirectional shock-resistant bracket for an air duct.

In order to achieve the above purposes, the technical scheme adopted by the utility model is as follows:

a bidirectional anti-seismic support for an air pipe comprises a hanger and a support frame, wherein the air pipe is arranged on the support frame, one end of the hanger is connected with the support frame, the other end of the hanger is connected with a ceiling, the support frame comprises an upper cross beam and a lower cross beam which are positioned on the upper side and the lower side of the air pipe, the two corresponding ends of the upper cross beam and the lower cross beam are fixedly connected through bolts, and the hanger is fixedly connected with the upper cross beam; the hanger comprises multiple hanging rods connected with two ends of the upper cross beam, each end of the upper cross beam is at least connected with two hanging rods, one of the two hanging rods is a vertical hanging rod, and the other hanging rod is at an included angle of 45 degrees with the vertical hanging rod and is positioned in a cross section perpendicular to the length direction of the air pipe together with the vertical hanging rod.

Furthermore, the hanger at least comprises a side-pulling hanger rod parallel to the section of the air pipe in the length direction, and the side-pulling hanger rod and the vertical hanger rod form an included angle of 45 degrees.

Furthermore, the upper and lower beams lock the air pipes from the upper and lower sides of the air pipes.

Furthermore, the contact surfaces of the upper and lower beams and the air pipe are wrapped by rubber layers.

And furthermore, the hanging bracket is composed of a plurality of C-shaped channel steels, and the outer wall of the hanging bracket is provided with a zinc coating.

After the technical scheme is adopted, the utility model has the beneficial effects that: the gallows that utilizes many square boxes is fixed to the support frame, no matter any direction takes place the vibration, all has corresponding jib to provide support and reduce the harm that the vibration produced to it. This technical scheme simple structure, it is effectual to combat earthquake.

Detailed Description

The following detailed description of embodiments of the utility model is provided in conjunction with the accompanying drawings:

as shown in the figure, the bidirectional anti-seismic support for the air duct is used for supporting the rectangular air duct 1. The rectangular air pipe 1 is suspended on a ceiling by a plurality of earthquake-proof supports distributed at equal intervals. The anti-seismic support consists of a hanging bracket and a support frame.

The hanger comprises an upper cross beam 2, a lower cross beam 3 and a screw type anchor bolt 4 which connects two corresponding ends of the upper cross beam and the lower cross beam. The upper cross beam and the

lower cross beams

2 and 3 are distributed on the upper side and the lower side of the rectangular air pipe 1, the upper cross beam and the

lower cross beams

2 and 3 are C-shaped channel steel, and zinc coatings are plated on the surfaces of the C-shaped channel steel to prevent corrosion. Screw crab-bolt 4 is taut and the lock with upper and

lower crossbeam

2,3, firmly fixes rectangle tuber pipe 1 between upper and

lower crossbeam

2,3, for providing the buffering, avoids damaging the tuber pipe, sets up the rubber layer on the contact surface of upper and

lower crossbeam

2,3 and rectangle tuber pipe 2, perhaps wraps up the buffer layer in upper and

lower crossbeam

2,3 outsides.

The support frame is composed of a pair of supporting units, and two ends of the upper cross beam 2 are respectively connected with one supporting unit. The bottom and the entablature 2 fixed connection of support frame, the top and the ceiling fixed connection of support frame are fixed the gallows through the support frame to the realization is fixed rectangular tuber pipe 1. In order to ensure the anti-seismic effect, the supporting unit comprises three supporting rods, the bottoms of the three supporting rods are fixedly connected to the end part of the upper cross beam 2, the first supporting rod 5 is vertically arranged and perpendicular to the top surface of the rectangular air pipe 1, and the second supporting rod 6 is obliquely pulled at 45 degrees and is parallel to the ventilation section of the rectangular air pipe 1; the third support rod 7 is also obliquely arranged at 45 degrees and is parallel to the side surface of the air pipe in the length direction. Three dimensions of three bracing piece in the space provide three-dimensional support to the gallows, and no matter which direction takes place vibrations, all can effective antidetonation.

Alternatively, the three support rods may be arranged in an inverted tetrahedral shape, the vertex of the tetrahedral shape is connected with the end of the upper beam 2, and three corner points of the ground of the tetrahedral shape are fixed to the ceiling. In order to improve the connection stability, the top of each support rod is welded with a connecting plate 8, and the connecting plates 8 are fixedly installed on the ceiling through screws.
