Embodiment 1

[0111] Example 1 The wooden door frame seismic reinforcement structure with upper channel steel overall length arrangement + lower channel steel overall length arrangement

[0112] The wooden door frame of a traditional residential building is proposed to be reinforced with the wooden door frame seismic reinforcement structure with the upper channel steel full length arrangement + the lower channel steel full length arrangement, as shown in Figure 1 to Figure 8 shown. The implementation steps are as follows:

[0113]Step 1: Open the upper groove 3-1 and the upper groove 5a-1 on the door frame beam 1-1. Open the lower groove 4-1 and the lower slot 5b-1 on the door frame column 2-1. 16-1 is the pedestrian door in the wooden door frame. The length of the door frame beam is 3m, the diameter of the door frame beam made of round wood is 0.18m, the height of the door frame column is 2.5m, the diameter of the door frame column made of round wood is 0.2m, and the depth of the upper ...

Embodiment 2

[0119] Example 2: Wooden door frame anti-seismic reinforcement structure with upper channel steel part arrangement + lower channel steel part arrangement

[0120] The wooden door frame of a farm house is planned to be reinforced with an anti-seismic reinforcement structure of wooden door frame with upper channel steel part arrangement + lower channel steel part arrangement, as shown in Figure 9 to Figure 15 shown. The implementation steps are as follows:

[0121] Step 1: Open the upper groove 3-2 and the upper groove 5a-2 on the door frame beam 1-2. Open the lower groove 4-2 and the lower slot 5b-2 on the door frame column 2-2. 16-2 is the pedestrian door in the wooden door frame. The length of the door frame beam is 3m, the diameter of the door frame beam made of round wood is 0.18m, the height of the door frame column is 2.5m, the diameter of the door frame column made of round wood is 0.2m, and the depth of the upper and lower grooves is 0.05m ,Such as Figure 9 shown....

Embodiment 3

[0127] Example 3 The wooden door frame seismic reinforcement structure with the upper channel steel arranged in full length + the lower channel steel partially arranged

[0128] The wooden door frame of an existing village and town building is proposed to be reinforced by the wooden door frame seismic reinforcement structure with the upper channel steel arranged in full length and the lower channel steel partly arranged, as shown in Figure 16 ~ Figure 23 shown. The implementation steps are as follows:

[0129] Step 1: Open the upper groove 3-3 and the upper groove 5a-3 on the door frame beam 1-3. Open the lower groove 4-3 and the lower slot 5b-3 on the door frame column 2-3. 16-3 is the pedestrian door in the wooden door frame. The length of the door frame beam is 3m, the diameter of the door frame beam made of round wood is 0.18m, the height of the door frame column is 2.5m, the diameter of the door frame column made of round wood is 0.2m, and the depth of the upper and lo...

Abstract

The invention relates to an aseismic reinforcing method of a wood door frame structure. The aseismic reinforcing method is characterized in that aseismic reinforcing is conducted on the intersection parts of door frame beams and door frame columns in a wood door frame, and thus an aseismic reinforcing structure of the wood door frame is formed. According to the aseismic reinforcing method, the angular displacement value of included angles of the intersection parts of the door frame beams and the door frame columns in the reinforced wood door frame can be significantly decreased, a pedestrian door in the wood door frame is effectively prevented from being clamped in an earthquake, and the valuable escape time is won for residents in the possible earthquake hazard.

Description

technical field [0001] This patent relates to an anti-seismic reinforcement method for a wooden door frame structure, which belongs to the field of reinforcement of wooden door frames. Background technique [0002] In earthquake disasters, the wooden door frames of traditional houses are often squeezed and deformed severely. Before the earthquake, the wooden door frame was a rectangular or approximately rectangular structure, and the angle between the intersection of the door frame beam and the door frame column was a right angle or approximately a right angle. After the earthquake, the wooden door frame was extruded and deformed into a parallelogram structure, and the door frame beam and door frame column The angle extrusion deformation of the intersecting parts is acute angle or obtuse angle. Therefore, the doors that were originally an important escape route for the victims of the earthquake area were stuck in the earthquake, making it difficult or even impossible to ope...
