Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the present invention provides an elastic anti-seismic device for wooden beams. On the one hand, for the bending deformation of wooden beams caused by instantaneous impact load and periodic fatigue damage, the device can The generated elastic force and the friction force between the laminates offset and absorb part of the energy, thereby prolonging the yield time of the failure process; on the other hand, improving the elastic deformation capacity of the wooden beam, when the failure load is not enough to make the wooden beam reach the plastic yield stage This device is able to restore the wooden beams to their original state when

Embodiment 1

[0050] Such as figure 1 As shown, the elastic anti-seismic device of the wooden beam includes several layers of wooden boards 2 arranged under the wooden beam 1. The wooden board 2 has at least two layers, and two U-shaped clamps 3 are used to tightly fix the two parts of the wooden beam 1 and the wooden board 2. end, the opening 4 of the U-shaped clamp 3 faces downward, that is, the U-shaped clamp 3 is installed on the upper end surface and side of the wooden beam 1, the opening 4 is provided with a pull bolt hole, and the pull bolt 5 runs through the Both ends of the pull bolt holes are fixed by nuts 6; the opening positions of the pull bolt holes are prefabricated according to the sum of the thickness of the plank 2 of all layers and the thickness of the wooden beam 1, and the two U-shaped clamps 3 along the Plank 2 length direction is set by actual distance; U-shaped clamp 3 inboard width is equal to described wooden beam 1 width, and U-shaped clamp 3 side height exceeds t...

Embodiment 2

[0072] Such as Figure 5 ~ Figure 7 As shown, the elastic anti-seismic device of the wooden beam includes several layers of equal-length wooden boards 2 arranged under the wooden beam 1, the wooden boards 2 are at least two layers, and the U-shaped clamp 3 tightly fixes the wooden beam 1 and the wooden board 2, so The opening 4 of the U-shaped clamp 3 faces downward, that is, the U-shaped clamp 3 is installed on the upper end surface and the side of the wooden beam 1, and the lower end of the U-shaped clamp 3 extends toward the middle of the plank 2 and forms a cross brace 9. The two cross braces 9 are all provided with through holes, and the corresponding positions of the planks 2 and the through holes are provided with positioning holes, and the positioning bolts 7 are interference fit and located at the corresponding through holes and the In the positioning hole, the interference fit of the interference fit is 0.1-0.2mm. The upper end surface of the U-shaped clamp 3 is cov...

Embodiment 3

[0085] Such as Figure 8-9 As shown, the difference between the present embodiment and embodiment 2 is only that the elastic anti-seismic device of the wooden beam includes several layers of planks 2 arranged in a fish-belly shape arranged below the wooden beam 1, and the planks 2 are at least three layer, and the U-shaped clamp 3 tightly fixes the wooden beam 1 and the wooden board 2 . There are at least three U-shaped clamps 3 .

Abstract

The invention discloses an elastic anti-seismic device for a wooden beam, which comprises several layers of wooden boards (2) arranged under the wooden beam (1), and at least two U-shaped clamps (3) tightly fix the wooden beam (1) and the wooden board ( 2), the opening (4) of the U-shaped clamp (3) is facing downward, and the opening (4) is provided with a pull bolt hole, and the pull bolt (5) passes through the rear ends of the pull bolt hole are fixed by nuts (6); the upper end surface of the U-shaped clamp (3) is provided with at least two through holes, and the corresponding positions of the wooden beam (1) and the through holes are provided with positioning holes, and the positioning The bolt (7) is located in the corresponding through hole and the positioning hole in a loose fit. The invention also discloses an installation method of the elastic anti-seismic device of the wooden beam. The invention can carry out environmental-friendly and high-efficiency repair in accordance with the self-shock-absorbing type of wooden houses for wooden beams without damage, cracks, small bending deformation, or about to break.

Description

technical field [0001] The invention relates to an elastic anti-seismic device for wooden beams and an installation method thereof, belonging to the technical field of wooden building environmental protection restoration. Background technique [0002] Wooden houses enjoy the reputation of "breathing houses" because they can automatically adjust the humidity. When the humidity is high, the wooden house can automatically absorb moisture, and when it is dry, it will release water from its own cells, thus playing a role of natural regulation. The wooden structure house is a healthy residence with many advantages such as green environmental protection, health, comfortable living, safety, closeness to nature, long service life and unique design style. [0003] Human beings have used wooden houses in the world for thousands of years. A large number of ancient buildings in China (such as pavilions, platforms, buildings, pavilions, pavilions, towers, pavilions, houses, and brackets) ...
