Embodiment 1

[0039] like figure 1 As shown, a flexible connection pipe 4 for earthquake-isolated buildings includes a corrugated pipe 11 and a joint 15 arranged at the end of the corrugated pipe 11, and a mesh sleeve 12 is sleeved on the outside of the bellows 11, and the mesh sleeve 12 and the joint The junction of 15 is fixed with net cover pressing ring 14, so that net cover 12 is fixed on the outside of bellows 11. In particular, a circular thermoplastic rubber liner 13 is provided inside the corrugated pipe 11 to improve the tensile strength and deformability of the flexible connecting pipe 4 and facilitate the removal of residues accumulated in the corrugated pipe 11 .

[0040] In order to prevent the rubber gasket 13 from collapsing under the pressure-free state, the rubber gasket 13 and the bellows 11 are bonded with Chemlock.

[0041] As a preference of this embodiment, the thickness of the rubber gasket 13 is 3 mm, the thickness of the single ring corrugation of the bellows 11 i...

Embodiment 2

[0052] Using the flexible connecting pipe 4 described in Embodiment 1, the thickness of the rubber gasket 13 is 3 mm, the thickness of the single ring corrugation of the bellows 11 is 1.8 mm, and the pitch between the corrugations is 3.5 mm.

[0053] When the flexible connecting pipe 4 needs to be installed vertically, such as image 3 As shown, this embodiment provides the specific technological process for the installation of flexible connection pipes for earthquake-isolated buildings as follows:

[0054] Step 1: Determine the net height of the isolation layer 2, determine the net height of the isolation layer 2 according to the use of the isolation layer 2 (underground garage, basement, etc.), and further determine the installation position and length of the flexible connecting pipe 4, flexible The length of the connecting pipe 4 should meet the displacement requirement of not less than the displacement of the isolation support under rare earthquakes;

[0055] Step 2: Duri...

Embodiment 3

[0061] When the flexible connecting pipe 4 described in Embodiment 1 is installed in the shock-isolation layer 2 in a horizontal direction, as Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides the specific technological process for the installation of flexible connection pipes for earthquake-isolated buildings as follows:

[0062] Step 1: Determine the net height of the isolation layer 2, determine the net height of the isolation layer 2 according to the use of the isolation layer 2 (underground garage, basement, etc.), and further determine the installation position and length of the flexible connecting pipe 4, flexible The length of the connecting pipe 4 should meet the displacement requirement of not less than the displacement of the isolation support under rare earthquakes;

[0063] Step 2: Pre-embed the fixed platform embedded parts 9 at appropriate positions on the top and bottom plates of the seismic isolation layer 2, and lay a ground-type mobile...

Abstract

The invention discloses a flexible connecting pipeline and a construction method for using the flexible connecting pipeline in base isolated buildings. The flexible connecting pipeline comprises a corrugated pipe and a joint connected to the end part of the corrugated pipe, wherein a net cover sleeves the corrugated pipe; a net cover pressing ring is arranged at the connecting part of the net cover and the joint; a circular thermoplastic rubber gasket is arranged on the inner side of the corrugated pipe. The flexible connecting pipeline is suitable for the base isolated buildings. The construction method comprises the following steps of 1) determining a net height of an isolation layer, 2) installing an isolation layer pipeline, 3) installing a fixed rack, 4) installing the flexible connecting pipeline. The flexible connecting pipeline is large in deformability and high in tensile strength, and residues accumulated in the pipeline are easy to clean. By the construction method, the problems that the isolation layer pipeline cannot deform during an earthquake and how pipelines are connected flexibly are solved; the method is easy to perform; the integral security of the base isolated buildings after the earthquake is improved; secondary disasters are prevented from being caused by the damaging of the isolation layer pipeline during the earthquake; the expectation effect of the base isolated buildings is achieved.

Description

technical field [0001] The invention belongs to the technical field of building earthquake isolation, relates to a flexible connecting pipe suitable for earthquake-isolated buildings, and also relates to a construction method for installing the flexible connecting pipe in an earthquake-isolation layer pipe. Background technique [0002] Earthquake is one of the most serious natural disasters faced by human society. The most tragic scene left by an earthquake to society is the destruction and collapse of buildings. Seismic isolation building is to install a seismic isolation device at the base of the building or a certain position to form a seismic isolation layer, which isolates the upper structure from the lower foundation, so as to consume seismic energy, avoid or reduce the transmission of seismic energy to the upper part, and can More effectively guarantee the safety of the upper structure and internal personnel and equipment. [0003] Building seismic isolation techno...
