Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wood structure reinforcement, and in particular relates to a wood structure reinforcement structure. Background Art
[0002] Cracks are one of the most common defects in wood. The impact of wood cracks on structural strength and stability varies to different degrees in different parts of the component.
[0003] For wooden rods in wooden trusses that only bear tension or pressure, a few slight cracks that are basically parallel to the axis of the rods have little effect on the bearing capacity of the components. However, cracks that appear at the shear surface and near the shear surface of the lower chord joint of the truss and its wooden plywood, or any other part that bears shear force will significantly reduce the shear strength of the wooden components, causing damage to the connection of the components, and in severe cases, the roof truss will collapse. Oblique cracks in other rods of the truss will also have an adverse effect on the truss. For compressive components, if the cracks are long and deep, the components will be divided into two halves, thereby reducing the rigidity of the components, and in severe cases, the components will lose stability. For bending components, longitudinal cracks appear on the bending side, which reduces the shear surface of the components. In particular, the shear stress at the ends of the components is the largest, and the side cracks will increase the shear deformation of the components, causing the upper and lower halves of the components to displace due to shear deformation.
[0004] When repairing cracked wooden columns, the traditional method is to fill and bond the cracks with glue according to the degree of cracking. When the cracks are larger and can be clearly seen, alum is added to newspaper scraps or wood scraps, and clean water is poured in. Stir evenly, and then the mixture is poured into the gap and the cracks are repaired after solidifying. However, this method of repair requires sandpaper to be used for polishing after the filler has solidified. In addition, there is a risk of damage to the furniture during the polishing process. At the same time, the repaired cracks will form a repair area that is obviously different from the color of the original wood structure, which affects the uniformity of the entire appearance. At the same time, the problem of decreased supporting force caused by the cracks cannot be effectively compensated. Utility Model Content

[0025] See also Figures 1 to 4The utility model provides the following technical solutions: a wood structure reinforcement structure, including a steel support plate 1, the inner sides of both ends of the steel support plate 1 are hinged with extrusion flip plates 2, and a clearance groove for cooperating with the rotation of the extrusion flip plate 2 is opened between the inner side of the steel support plate 1 and the extrusion flip plate 2, a pleated connecting plate 21 is fixedly connected between one side of the extrusion flip plate 2 and the inner side of the end of the steel support plate 1, and two through grooves 11 are opened inside the steel support plate 1, and the two through grooves 11 are distributed up and down;
[0026] A traction steel wire rope 3 is fixedly connected to one side of the extrusion flip plate 2, and the other ends of the two traction steel wire ropes 3 respectively pass through the inside of the two through grooves 11 and then pass through the outside of the steel support plate 1. The outer end of the traction steel wire rope 3 is fixedly connected to a fixing plate 31. Installation grooves 12 are provided on both sides of the steel support plate 1, and the positions of the two fixing plates 31 correspond to the positions of the two installation grooves 12 respectively.
[0027] Under the action of the steel support plate 1, good support can be provided to the area where cracks appear in the wooden structure column after being replaced, thereby avoiding the situation where the support performance of the entire wooden structure column decreases after being partially cut.
[0028] In this embodiment, the steel support plate 1 is the basic frame of the entire wood structure reinforcement structure, and is also used to provide a connection carrier for the extrusion flip plate 2. The two extrusion flip plates 2 installed on the inner side of the steel support plate 1 are used to extrude and pull the wood structure columns with cracks, and by extruding the wood structure columns on the outside, the cracks on the wood structure columns are assisted to close, thereby reducing the adverse effects of further enlargement of the cracks on the wood structure columns on the supporting performance of the wood structure columns. The traction steel wire rope 3 installed on one side of the extrusion flip plate 2 and passing through the inside of the steel support plate 1 is used to pull the extrusion flip plate 2, wherein the outer end of the traction steel wire rope 3 installed on the left extrusion flip plate 2 extends from the right side of the steel support plate 1 to the outside, while the traction steel wire rope 3 installed on the right extrusion flip plate 2 The outer end of the steel support plate 1 extends from the left side of the steel support plate 1 to the outside. When it is necessary to reinforce the wooden structure column with cracks, first, the wooden block in the cracked area on the wooden structure column is cut off with a tool, and the cutting groove is matched with the steel support plate 1. Then, the reinforcement assembly formed by the steel support plate 1 and the extrusion flip plate 2 is placed in the cutting groove, and then the outer end of the traction wire rope 3 is pulled outward. At this time, the extrusion flip plate 2 is flipped toward the direction close to the wooden structure column after being pulled by the traction wire rope 3, and the outer side of the wooden structure column is squeezed. After the outer side of the wooden structure column is squeezed, the crack compression can be performed on the cracked area. Then, the end of the traction wire rope 3 is fixed to the inside of the installation groove 12 by the fixing plate 31 to complete the reinforcement of the cracked wooden structure column.
[0029] With the cooperation of the extrusion flip plate 2 and the traction wire rope 3, the outside of the area where cracks appear on the wooden structure pile can be squeezed, and the cracks on the wooden structure can be compressed by squeezing on the outside of the wooden structure column to assist in the recovery of the crack area. At the same time, it can reduce the adverse effects caused by further expansion of the crack range after cracks appear on the wooden structure column again.
[0030] A glue injection groove 4 is formed between the inner side of the steel support plate 1 and the outer side of the wooden structure column, and the inside of the glue injection groove 4 is injected with internal strong adhesive 41, and the steel support plate 1 and the wooden structure column are fixed by the internal strong adhesive 41; wherein the internal strong adhesive 41 is used to provide a connecting carrier for the fixation between the steel support plate 1, the extruded flip plate 2 and the wooden structure column, and when the fixing component is placed inside the cutting groove, the internal strong adhesive 41 is applied to the inside of the cutting groove and one side of the steel support plate 1 and the extruded flip plate 2.
[0031] It should be noted that the outside of the steel support plate 1 is fixedly connected to the log pile outer plate 5 by an external strong adhesive 51, and the log pile outer plate 5 forms a flat plane with the outside of the wooden structure column; after the crack compression of the outer side of the wooden structure column is completed by the extrusion flip plate 2, the log pile outer plate 5 on the wooden block cut from the wooden structure column is cut and separated, and after the cutting is completed, the log pile outer plate 5 is bonded to the outside of the steel support plate 1 by the external strong adhesive 51, so that the entire wooden structure column can still maintain its original appearance after reinforcement.
[0032] It should also be noted that an elastic protective plate 22 is fixedly connected between one side of the extrusion flip plate 2 and the inner side of the steel support plate 1, and the arc surface of the elastic protective plate 22 is concave toward the clearance groove between the steel support plate 1 and the extrusion flip plate 2; wherein the elastic protective plate 22 plays a protective role to prevent the internal strong adhesive 41 from entering the clearance groove and affecting the flipping of the extrusion flip plate 2.
[0033] Two through holes 32 are provided inside the steel support plate 1 for the outer end of the traction wire rope 3 to pass through, and the two through holes 32 correspond to the positions of the two through grooves 11 respectively; wherein the through holes 32 are used to provide a space for the end of the traction wire rope 3 to pass through to the outside, wherein the outer end of the traction wire rope 3 passes through the through holes 32 to the outside in order to prevent the squeezing of the flip plate 2 and the two sides of the steel support plate 1 from interfering with the penetration of the traction wire rope 3.
[0034] In this embodiment, the two side edges of the log pile outer plate 5 are located outside the two side edges of the steel support plate 1. At this time, the outside of the log pile outer plate 5 can form a closed whole with the outer surface of the wooden structure column.
[0035] Under the effect of the log pile outer plate 5, after the cracked wooden structure column is reinforced and repaired, the exterior can still maintain a good original shape, reducing the inharmoniousness of the appearance of the wooden structure column after the cracks in the wooden structure column are repaired.
[0036] The working principle and use process of the utility model are as follows: when it is necessary to reinforce a wooden structure column with cracks, firstly, the wooden block in the cracked area on the wooden structure column is cut off with a tool, and the cutting groove is matched with the steel support plate 1, and then the outer side of the steel support plate 1 and the extrusion flip plate 2 and the inside of the cutting groove are coated with internal strong adhesive 41. After the internal strong adhesive 41 is coated, the reinforcement assembly formed by the steel support plate 1 and the extrusion flip plate 2 is placed in the cutting groove, and then the outer end of the traction wire rope 3 is pulled outward. At this time, the extrusion flip plate 2 is flipped in the direction close to the wooden structure column after being pulled by the traction wire rope 3. The outer side of the wooden structure column is squeezed, and after the outer side of the wooden structure column is squeezed, the crack compression can be performed on the cracked area, and then the end of the traction wire rope 3 is fixed to the inside of the installation groove 12 through the fixing plate 31 to complete the reinforcement of the wooden structure column with cracks. After the crack compression after squeezing the outer side of the wooden structure column by the squeezing flip plate 2 is completed, the log pile outer plate 5 on the wooden block cut from the wooden structure column is cut and separated, and after the cutting is completed, the log pile outer plate 5 is bonded to the outside of the steel support plate 1 by the external strong adhesive 51, so that the entire wooden structure column can still maintain its original appearance after reinforcement.
