Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a pre-buried vibration-damping pipeline hanger structure. Background Art

[0002] In the field of building engineering construction, ventilation ducts, water supply pressure ducts, etc. are usually fixed and hoisted under the basement or the roof of the house through pipe brackets. The traditional construction method is to drill holes in the basement roof through mechanical drilling, install expansion bolts in the holes, and use expansion bolts to connect the hanger and the bracket to support the ventilation ducts and pressure ducts. During the pipe hoisting process, it is necessary to provide a hanging point every 600mm. For large buildings, the construction volume is large.

[0003] During the drilling process, there are often problems such as positioning deviation or errors during the construction process, which may cause the drilling hole to encounter the steel bars in the top plate. In order to avoid damaging the steel bars and affecting the structural strength, it is necessary to drill holes twice to avoid the steel bars, which is time-consuming and labor-intensive during construction.

[0004] After the lifting construction is completed, due to the impact of air volume or water hammer effect in the pipeline, the influence of external factors such as long-term vibration and impact of various pipelines, it is easy to cause the expansion bolts to loosen, affecting the bearing capacity. In severe cases, the bolts will loosen and fall off, lose their supporting capacity, and then cause the pipe body to deflect, bend or even break, eventually leading to air and water leakage, resulting in quality accidents and affecting the use function.

DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0021] like Figure 1-2 As shown, a pre-buried vibration-damping pipe hanger structure consists of two parts: a mounting box body 1 and a hanger rod 2, and is used for adjustable hanging of the buffer chamber of the basement air duct and other pipes.

[0022] The installation box body 1 is pre-embedded and pre-installed in the steel frame of the top plate 3 before the top plate is cast. The installation box body 1 is a metal shell or a plastic shell. The installation box body 1 is sunken into the building top plate 3 to be cast, and a sunken fault surface 4 is left between the plane of its bottom and the bottom surface of the concrete top plate 3. In order to fix the installation box body 1, a limiting ear 5 is installed on its side. The limiting ear 5 adopts an L-shaped anchor bar or an angle iron. Before casting, the limiting ear 5 is fixed to the steel bar of the top plate 3, so that the installation box body is fixed. This pre-embedded construction method can ensure the accuracy of the position of each hanging point during the construction process, and will not cause any damage to the cast concrete top plate during the installation of the hanger.

[0023] The bottom of the installation box body 1 is open, and a bottom plate 6 is installed on the inner side of the opening. The bottom opening of the installation box body 1 is as follows: the bottom of the two opposite side surfaces is bent inward at right angles twice to form a horizontal support surface 7 and a vertical upward limit surface 8; a mounting groove 9 is formed between the two limit surfaces 8 for mounting the bottom plate 6. The two ends of the bottom plate 6 are bent downward at right angles to form two right-angle limit portions 10 at the two ends. The bottom plate 6 is loaded into the installation box body 1 from the mounting groove 9, and the bottom surfaces of the two right-angle limit portions 10 of the bottom plate 6 are correspondingly supported on the two support surfaces 7 of the installation box body, and are limited by the corresponding limit surfaces 8; there is an adjustment gap between the two right-angle limit portions 10 of the bottom plate 6 and the limit surface 8 of the installation box body 1, and there is a gap between the bottom surface of the bottom plate 6 and the top surface of the limit surface 8. It is convenient for the bottom plate 6 to have adjustment space in the installation box body 1 when vibration occurs. A waist-shaped hole 11 is provided in the middle of the bottom plate 6, and the length direction of the waist-shaped hole 11 is perpendicular to the limiting direction of the limiting surface 8. The suspension rod 2 passes through the waist-shaped hole 11, and there is also space for adjustment of the suspension rod 2 in the waist-shaped hole 11.

[0024] The suspension rod 2 is a screw rod, the upper end of the suspension rod 2 is installed in the installation box body 1, and the lower end of the suspension rod 2 is fixedly connected to the installation frame of the pipeline. The interior of the installation box body 1 is a cavity, and a vibration reduction structure is installed at one end of the suspension rod 2 located in the installation box body. The vibration reduction structure consists of a tray 12, a spring 13, a rubber block 14 and a nut 15. The tray 12 is a U-shaped tray and is welded to the top of the suspension rod 2. The rubber block 14 is fixedly installed in the tray 12 and cooperates with the inner top surface of the installation box body 1; the setting of the rubber block 14 is used to prevent the top of the suspension rod 2 from colliding with the installation box body 1 when the suspension rod 2 is extended and retracted under vibration. The spring 13 is sleeved on the suspension rod 2 and squeezed between the tray 12 and the bottom plate 6. When the suspension rod 2 is hoisting the pipeline, it is in a stressed state, and the spring is compressed. When the pipeline vibrates, the force on the suspension rod 2 changes. The extension and retraction of the spring can buffer the impact and provide an adjustment space for the suspension rod to adapt to vibration in the vertical direction. A spring washer is installed on the suspension rod 2, and the spring washer is located between the top surface of the spring 13 and the bottom plate 5. In order to limit the expansion and contraction of the spring 13, a nut 15 is installed on the suspension rod 2, and the nut 15 is pressed against the bottom surface of the bottom plate 6.

[0025] A sealing plate 16 is installed at the bottom of the installation box body 1, and the sealing plate 16 blocks the installation groove 9 at the bottom of the installation box body. The sealing plate 16 is connected to the bottom plate 6 by a screw. At the same time, a plastic panel 17 is filled in the gap between the installation box body 1 and the bottom surface of the concrete casting surface to ensure the beauty of the hanging point. The hanging rod 2 passes through the plastic panel 17 and the sealing plate 16.
