Description

Technical Field

[0001] The present invention belongs to the technical field of wooden structure building supports, and particularly relates to a support structure for the renovation of wooden structure buildings. Background Technique

[0002] At present, there is a large stock of existing wooden structure buildings in our country, which cover a large number of historical and cultural heritage protection buildings. They are precious cultural heritages of the Chinese nation and contain rich historical and cultural values. Due to changes in the use purposes of wooden structure buildings and structural damages, etc., it is necessary to renovate and reinforce them. However, at present, the existing reinforcement technologies and methods are mainly used for buildings with structural forms such as brick-concrete structures, concrete structures, and steel structures, and the reinforcement and repair methods for wooden structure buildings need to be studied and innovated.

[0003] Due to the influence of wind, rain erosion and human activities on wooden structure buildings, and the lack of effective maintenance at the same time, different degrees of aging, damage, etc. have occurred. Many main load-bearing members such as wooden beams and columns are severely cracked and decayed, and have basically lost their bearing capacity and need to be removed and replaced; while the wooden beams and columns with characteristic carved patterns record social development and historical changes and have extremely high historical and cultural values. It is necessary to follow the principle of "preserving the status quo and restoring the old as it was", retain the original style, which puts forward higher requirements for the design of the reinforcement plan.

[0004] The existing wooden structure reinforcement and repair mainly include column pier connection, column replacement, partial replacement of beam, purlin, rafter and wing angle, component tenon pulling reinforcement, etc. These reinforcement forms do not enhance the overall stability and safety of wooden structure buildings, but only restore the original stress-bearing capacity of the structure, and it is difficult to meet the requirements of the existing structural design specifications, especially in the case of increased use loads caused by changes in building functions. Therefore, it is necessary to make improvements. Summary of the Invention

[0005] The purpose of the present invention is to provide a support structure for the renovation of wooden structure buildings to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A support structure for the renovation of wooden structure buildings, including side wall steel plates. There are two side wall steel plates. U-shaped notches are opened in the middle of the upper ends of the two side wall steel plates. Support blocks are connected to both sides of the upper ends of the two side wall steel plates and located on both sides of the U-shaped notches. A support steel plate is provided on the upper end surface of the support block. A horizontal support plate is installed on the upper end of the support steel plate through screws.

[0023] The present invention provides a support structure for the renovation of a wooden structure building as shown in Figures 1-6 , including side wall steel plates 1. There are two side wall steel plates 1. U-shaped notches 8 are opened in the middle of the upper ends of the two side wall steel plates 1. Support blocks 4 are connected to both sides of the upper ends of the two side wall steel plates 1 and located on both sides of the U-shaped notch 8. The shape of the support block 4 is set as a T shape. The upper ends of the side wall steel plates 1 are stuck at the corners on both sides of the support block 4 and fixed by welding. The upper end surface of the support block 4 is provided with a support steel plate 6. The horizontal support plate 5 is installed on the upper end of the support steel plate 6 by screws. Mounting holes 2 are provided at the bottom of the side wall steel plates 1. Support columns 3 are connected through screws in the mounting holes 2. Strengthening supports 16 are provided inside the side wall steel plates 1 and at the bottom of the U-shaped notch 8. The setting of the strengthening supports 16 can increase the support area, reduce the local pressure, and reduce the extrusion deformation of the original structural wooden beam of the support.

[0024] The support block 4 is internally provided with a cavity. An installation block 7 is arranged in the cavity of the support block 4. The installation block 7 is arranged as a hollow structure and has an opening at the lower end surface. A lifting mechanism is arranged in the installation block 7. The lifting mechanism includes a fixed block 9 and a sliding block 10. Fixed blocks 9 and sliding blocks 10 are arranged at the top of the inner cavity of the installation block 7 and the bottom of the inner cavity of the support block 4. A lead screw 12 is rotatably arranged at the bottom of the inner cavity of the support block 4. The lead screw 12 passes through the fixed block 9 and the sliding block 10, and the lead screw 12 is threadedly connected to the sliding block 10. The upper and lower fixed blocks 9 and sliding blocks 10 cross-connect two rotating rods 11, and the middle parts of the two rotating rods 11 are rotatably connected by a pin; the thread directions on both sides of the middle part of the lead screw 12 are opposite. There are two groups of lifting mechanisms. When the lead screw 12 rotates, the sliding blocks 10 of the two groups of lifting mechanisms move outward to raise the installation block 7. The support steel plate 6 is arranged at the upper end of the installation block 7. One end of the lead screw 12 is connected to a rotating head 13. An internal hexagonal hole is opened inside the rotating head 13. By inserting a tool into the internal hexagonal hole to rotate the rotating head 13, the lead screw 12 is driven to realize lifting. An insertion hole 14 is opened on the outside of the rotating head 13. A plug 15 is screwed in the insertion hole 14. The outer end of the plug 15 is hexagonal in shape, and a slotted screwdriver slot is opened on the plug 15. A wrench or a slotted screwdriver can be used for the disassembly and assembly of the plug 15.

[0025] During the use of the support structure for the renovation of wooden structures, the dimensions of the original structural wooden beam are measured, and a U-shaped notch 8 is made on the sidewall steel plate 1 according to the measured dimensions of the original structural wooden beam. Then, the support column 3 is installed. The original structural wooden beam is stuck in the U-shaped notch 8, so that the support column 3 and the sidewall steel plate 1 support the original structural wooden beam. A certain number of horizontal support plates 5 are taken according to requirements and connected to the support steel plates 6 on the adjacent sidewall steel plates 1. The support steel plates 6 can bear the load transmitted from the upper floor slab, and the height of the support steel plates 6 can be adjusted according to the height of the upper support position, which is convenient and practical; when adjusting, a tool is inserted into the rotating head 13 in the insertion hole 14, and the tool is rotated to drive the lead screw 12 to rotate, driving the sliding blocks 10 of the two groups of lifting mechanisms to move outward, so that the installation block 7 rises and the support steel plate 6 rises, and the height adjustment is completed, which is very convenient; the installation block 7 is arranged as a hollow structure, and the relevant components of the lifting mechanism are stored inside, saving space.
