Detailed Description

The inventive concept will be described in detail below with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate that other ways of implementing the present invention on the basis of the preferred embodiment will also fall within the scope of the present invention. In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "longitudinal", "transverse", etc., are used with reference to the directions as illustrated in the accompanying drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.

Referring to fig. 1-2, wherein fig. 1 shows a prefabricated building 1 for a tunnel according to a preferred embodiment of the present invention, fig. 2 is an exploded view of a shock absorbing mechanism 30 of fig. 1. As shown in fig. 1 and 2, the prefabricated building 1 according to the present invention includes a prefabricated vertical beam 10, a prefabricated upper beam 20, a damping mechanism 30, and the like. The prefabricated vertical beam 10 and the prefabricated upper beam 20 can be transported to a construction site after the pouring prefabrication of a pouring workshop is finished in advance, or can be assembled after the pouring prefabrication is carried out on the construction site.

Referring to fig. 1, prefabricated vertical beams 10 can be fixed to both sides of a tunnel, and protrusions 11 protruding upward and having a hemispherical shape are formed at positions on the upper surface thereof. The projecting portions 11 extend substantially to both sides in the thickness direction of the precast girders 10. In particular, if the prefabricated upright beam 10 is formed in a column structure, the protrusion 11 covers substantially the entire upper surface of the prefabricated upright beam 10. The prefabricated uprights 10 are generally assumed to be positioned adjacent to the side walls of the tunnel on both sides, and the lower part can be fixed to the underlying foundation by means of cast-in-place and/or anchor-fastening. Other connection methods commonly used in the art, such as socket joint fixing, may also be used between the prefabricated vertical beam 10 and the foundation, and are not described herein again.

Note that the term "hemispherical shape" in the present invention does not mean that the protrusion 11, the depression 21, or the metal partition 32 exactly spans over a hemisphere, and in fact, the span of each portion or member may be slightly smaller than that of a hemisphere. For example, the central angle θ corresponding to the projection 11 of the precast girders 10 is preferably set to any angle in the range of 90 ° to 180 °. It will be appreciated that the central angles of the recess 21 and the metal partition 32 are now of the same design, thereby ensuring that they fit into one another.

With continued reference to fig. 1, the prefabricated upper girders 20 can be erected and fixed on the prefabricated vertical girders 10 positioned at both sides of the tunnel. The lower surfaces of both ends of the prefabricated upper girder 20 are respectively formed with depressions 21 matching the shape of the protrusions 11. In some embodiments of the precast upper girder 20 having a large span, as shown in fig. 1, another precast column 50 may be optionally added to the middle of the precast upper girder 20, thereby increasing the overall strength of the precast structure.

Referring to fig. 2 in conjunction with fig. 1, the shock-absorbing mechanism 30 provided between the recess 21 of the prefabricated upper girder 20 and the protrusion 11 of the prefabricated upright girder 10 is composed of a first elastic shock-absorbing pad 31, a metal spacer 32, and the like. Specifically, the damping mechanism 30 is provided with a first elastic damping pad 31, a metal partition 32, and a first elastic damping pad 31, which are stacked in sequence from top to bottom. The upper first elastic cushion 31 can be attached to the upper surface of the protrusion 11, and the lower first elastic cushion 31 is attached to the lower surface of the recess 21. The thickness of the first elastic cushion 31 is preferably set to not less than 6cm, for example, 8cm, 10cm, or the like. The first elastic cushion 31 is preferably provided as a rubber pad, thereby ensuring that it can withstand a relatively heavy upper beam and withstand the stress applied by the prefabricated upper beam 20 in a vibration environment.

The metal spacer 32 sandwiched by the first elastic cushion 31 on both the upper and lower sides has a shape matching the shape of the protrusion 11 and the recess 21. Preferably, the metal separator 32 is made of a metal material having high hardness and deformation resistance, for example, the metal separator 32 may be made of alloy steel. The metal partition plate 32 interposed between the two first elastic shock absorbing pads 31 can improve the deformation resistance of the shock absorbing mechanism 30, and prevent the rubber pads from being partially rolled and folded.

After the prefabricated building 1 is assembled, when various types of vibration occur in the tunnel due to the driving of passing vehicles or the earthquake at the tunnel location, the prefabricated upper beam 20 can slightly move in any direction relative to the prefabricated vertical beam 10 through the cooperation of the hemispheroid-shaped protrusion part 11 and the depression part 21 and the shock absorption mechanism 30 between the two, so that the prefabricated building 1 has certain flexibility to a certain extent, and the risk that the prefabricated building 1 made of rigid materials breaks and collapses is solved.

With continued reference to fig. 1, in a preferred embodiment the prefabricated upper beam 20 consists of a horizontally extending horizontal beam portion 22 and a vertically extending vertical beam portion 23. Wherein, the vertical beam portion 23 is provided with an anchoring member capable of penetrating the wall thickness thereof. Correspondingly, the prefabricated upright beams 10 are also correspondingly provided with anchors which may extend through the wall thickness thereof. The prefabricated building 1 further comprises a fixing plate 40 that can be penetrated by both the anchor at the vertical beam section 23 and the anchor at the prefabricated girder 10. When the device is used, the upper end and the lower end of the fixing plate 40 are respectively sleeved on the anchoring part positioned on the vertical beam part 23 and the anchoring part positioned on the prefabricated vertical beam 10, and the nut is screwed, so that the fixing plate 40 can wrap the damping mechanism 30, and the damping mechanism 30 is prevented from obviously displacing relative to the prefabricated vertical beam 10 and the prefabricated upper beam 20.

Alternatively, the metal diaphragm 32 is formed with vertical arms 32A at both ends thereof, respectively, and the vertical arms 32A are formed with fastening holes through which the anchors pass. At this time, the vertical arm 32A has a function equivalent to that of the fixing plate 40. It will be appreciated that the vertical arm 32A and the fixed plate 40 may be used in the same solution.

Although only the damper mechanism 30 composed of two first elastic damper pads 31 and one metal spacer 32 is described above, the damper mechanism 30 may be provided with more elastic damper pads in fact. In a preferred embodiment, two second elastic shock absorbing pads may be added to the shock absorbing mechanism 30. Wherein a second elastic cushion can be arranged between each first elastic cushion 31 and the metal separator 32. The thickness of the second elastic cushion is smaller than the thickness of the first elastic cushion 31.

For the prefabricated upright beam 10 of the prefabricated building 1, it may be formed in the form of a wall body, thereby forming a prefabricated upright wall.

Referring to fig. 3, there is shown a schematic cross-sectional view of a metal separator 32' according to another preferred embodiment of the present invention. Unlike the metal separator 32 shown in fig. 1 and 2, in this embodiment, the metal separator 32' has a wave shape having peaks and valleys in at least one cross section parallel to the thickness direction of the metal separator. Preferably, the metal separator 32' has a wave shape in any cross section parallel to the thickness direction of the metal separator. For convenience of description, the metal separator 32 'may have a wave shape in any vertical section when the metal separator 32' is horizontally placed with its protruding side facing upward.

For the corrugated metal separator 32', the distance D (half wavelength) between adjacent peaks and valleys is taken from any value within the interval of 30cm to 80cm, for example, 50cm, 60cm, etc., which can be set according to the overall size and weight of the prefabricated building 1. In general, the larger the overall size and the larger the weight of the prefabricated building 1, the larger the distance D can be set; conversely, the distance D may be set to a smaller value.

When the metal partition plate 32' is provided in a wave shape, the upper and lower surfaces of the rubber pad are correspondingly provided in a wave shape.

Advantageously, the damping mechanism 30 of this embodiment can be more firmly integrated with the prefabricated upper girder 20 and the prefabricated upright girder 10, and the damping mechanism 30 is not easily displaced with respect to the prefabricated upper girder 20 and the prefabricated upright girder 10 while having a good damping effect.
