Embodiment 1

[0082] refer to figure 1, an adjustable beam bottom wedge device includes a pre-embedded component 2, a distance-adjusting component 5, a temporary locking component 4 and an interference component 3, the pre-embedded component 2 is set in the prefabricated beam 1, and the temporary locking component 4 is detachably set On the assembly 2 and the interference assembly 3, the interference assembly 3 is located below the embedded assembly 2, and the side of the interference assembly 3 away from the embedded assembly 2 interferes with the support 6, and the distance adjustment assembly 5 is arranged on the interference assembly 3, and the distance adjustment assembly 5 is used to adjust the distance between the conflicting component 3 and the embedded component 2; during construction, the embedded component 2 is first set in the prefabricated beam 1, the prefabricated beam 1 is lifted, and the conflicting component 3 is installed on the On the pre-embedded component 2, move the pr...

Embodiment 2

[0112] refer to Figure 6 , The difference between this embodiment and Embodiment 1 is that the adjustment groove 22 includes a pitch-adjustable deep groove 24 .

[0113] refer to Figure 6 , the distance adjustment deep groove 24 includes the installation groove 25 that is arranged on the bottom wall of the prefabricated plate 20, the groove width of the installation groove 25 is greater than the outer diameter of the distance adjustment sleeve 51, the notch of the installation groove 25 faces the support 6 side, and the installation groove The groove bottom wall of 25 is provided with hemispherical groove 26.

[0114] The implementation principle of Embodiment 2 of the present application is: when installing, extend the distance-adjusting sleeve 51 and the rotating block 52 into the installation groove 25, and the rotating block 52 extends into the hemispherical groove 26 and aligns with the groove wall of the hemispherical groove 26. In this way, the depth of the rotating...

Embodiment 3

[0124] refer to Figure 7 The difference between this embodiment and Embodiment 1 is that the embedded assembly 2 includes at least two prefabricated blocks 21, and the prefabricated blocks 21 can be embedded in the prefabricated beam 1, or can be welded on the bottom wall of the prefabricated beam 1, In this embodiment, the prefabricated block 21 is pre-embedded in the prefabricated beam 1. The prefabricated block 21 can be two, three, or four. In this embodiment, three prefabricated blocks 21 are used, and the hemispherical groove 23 is arranged on the prefabricated block On the bottom wall of 21, the opening of the hemispherical groove 23 faces the side of the support 6.

[0125] refer to Figure 7 , the prefabricated block 21 is fixed with an anchoring steel bar 29, the anchoring steel bar 29 is pre-embedded in the prefabricated beam 1, the anchoring steel bar 29 can be arranged on the top wall of the prefabricated block 21, can be arranged on the peripheral wall of the p...

Abstract

The invention relates to an adjustable beam bottom wedge-shaped device and a beam body installation technology. The device comprises a pre-embedded assembly arranged in a precast beam and an abutting assembly used for making contact with a support, and the abutting assembly is arranged on the pre-embedded assembly; the abutting assembly is provided with a distance adjusting assembly used for adjusting the distance between the abutting assembly and the pre-embedded assembly. The adjustable beam bottom wedge-shaped device has the advantages that horizontal pressure bearing and vertical force transmission of the support are guaranteed, the hidden danger of plane creeping caused by inclination of the support or a beam body is eliminated, and bias pressure of the support is avoided; the beam body mounting gradient and erection elevation of the fabricated bridge in the mounting process can be adjusted, the counter-force of each support can be adjusted, the support can be prevented from disengaging, it is ensured that the actual pressure value borne by the support is consistent with the design value, the possibility of local damage to the fabricated bridge can be reduced, and the construction quality of the bridge can be improved; and therefore, the maintenance cost of the fabricated bridge in the operation period is reduced, and good social and economic benefits are achieved.

Description

technical field [0001] The application relates to an accessory device of a bridge or a building structure and a construction process of the bridge or a building structure, in particular to an adjustable beam bottom wedge device and a beam body installation process. Background technique [0002] The prefabricated bridge or building structure is a bridge or building structure formed after being processed in a prefabricated component factory, then transported to the construction site for hoisting and splicing. Compared with the traditional construction method of tying steel bars and pouring concrete on site, it has Short construction period, high construction quality, less environmental pollution and other advantages, so the prefabricated bridge or building structure is the development trend of my country's construction and transportation industry. [0003] During the on-site construction of prefabricated bridges or building structures, prefabricated beams need to be hoisted and...
