Description

An Ancient Building Wooden Column Dovetail Tenon Pier Joint Reinforcement Structure

technical field

The utility model relates to the technical field of protection and repair of ancient building columns, in particular to an ancient building wooden column dovetail pier joint reinforcement structure.

Background technique

The column is the component that vertically bears the upper load in the large wooden frame of the ancient building, and it is one of the most important components that constitute the building. The pillars are in contact with the ground or exposed to the outdoors all the year round, and are eroded by wind and rain, so they are very easy to decay. The wooden columns concealed in the wall are more likely to decay due to damp, poor ventilation and other reasons. Most of the decay of wooden pillars occurs at the root, and in this case, local repairs to the decayed parts are required. The means of treatment shall be determined according to the decay of the column root. When the damaged area of the column is not more than 1/3 of the cross-sectional area of the column or the base of the exposed column is severely decayed but the height from the bottom of the column does not exceed 1/5 of the height of the bottom layer of the column or The damaged length of the concealed column shall not be greater than 1/3 of the column height (bottom height), and the method of piering the column foot should be adopted. Pier connection is to cut off the rotten part of the column and replace it with new material. A common practice is to do half-mortise pier joints. The structure is to cut off 1/2 of the diameter of the connected columns as the overlapping part, and the stubble part is fastened with 2-3 iron hoops to enhance the integrity.

Although this traditional column root pier connection method has a certain degree of rigidity, the integrity and seismic performance of the overlapping parts are insufficient, and the phenomenon of displacement of the stubble part is very easy to occur, resulting in uneven stress on the column root. Uniform subsidence or ground vibration can easily cause the pier connection part of the column to loosen and shift in the up and down direction or left and right directions, resulting in failure of the reinforcing iron hoop, thus threatening the safety of the joint.

Utility model content

The purpose of this utility model is to provide a dovetail tenon pier joint repair structure for ancient building columns, which can ensure the stiffness of the pier joints and strengthen the overall structure of the pier joints without changing the ancient building raw materials and construction technology principles. performance and anti-seismic performance to solve the problems mentioned in the background technology.

An ancient building wooden column dovetail pier joint reinforcement structure, including the original column and pier-connected new column, the pier-connected new column includes dovetail tenon, new column facade and base, and the new column facade is arranged above the base along the vertical direction There is a dovetail tenon above the facade of the new column. The dovetail tenon is in a symmetrical dovetail shape. The width and length of the plane of the tenon are consistent with the width and length of the plane on the facade of the new column. The interval is an acute angle, and there is a mortise above the elevation of the original column section, and the dovetail tenon is inserted into the mortise of the original column section, so that the original column and the pier-connected new column are fixed together by mortise and tenon connection, and are reinforced with iron hoops at the overlap of the pier joints .

As a further description of the above-mentioned technical solution, the shape of the mortise is the same as that of the dovetail tenon, and they are interference fit.

As a further description of the above technical solution, the overlapping length of the two connected wooden columns should be 2~3 times of the column diameter.

As a further description of the above-mentioned technical solution, 2-3 iron hoops are used to lock and reinforce the overlapping joints of the piers.

Compared with the prior art, the utility model has a simple structure and a reasonable structure. On the basis of insisting on not changing the raw materials of ancient buildings and the principle of construction technology, the pier connection of the column root not only ensures the rigidity of the stubble connection part, but also strengthens the rigidity of the pier connection part. Flexibility and integrity.

detailed description

Below in conjunction with specific embodiment, the utility model is described further. It should be understood that the following examples are only used to illustrate the utility model but not to limit the scope of the utility model.

Referring to Figures 1-3, the utility model provides an ancient architectural wooden column dovetail pier connection reinforcement structure, which includes the original column 1 and the pier-connected new column 2, and the pier-connected new column 2 includes the dovetail tenon 201 and the new column facade 202 And the base 203, the new column facade 202 is arranged on the top of the base 203 along the vertical direction, the top of the new column facade 202 is provided with a dovetail tenon 201, and the dovetail tenon 201 is in a symmetrical dovetail shape, and the width and length of the tenon plane are the same as the new The width and length of the plane on the column facade 202 are consistent, and the angle between the inner hypotenuse of the tenon tail and the new column facade 202 is an acute angle. The purpose is to increase the force-bearing area of the new column and make the joint more stable. There is a mortise 101 on the top, and the dovetail mortise 201 is inserted into the mortise 101 of the cross-section of the original column 1, so that the original column 1 and the pier-connected new column 2 are connected and fixed together, and are reinforced with iron hoops 3 at the overlap of the pier.

The shape of the mortise 101 is the same as that of the dovetail tenon 201, which is an interference fit. The purpose of adopting the overlapping structure of the dovetail tenon pier is to prevent the pier-joined columns from sliding and shifting. Tight, increasing the stability of the node.

The overlapping length of the two connected wooden columns should be 2~3 times of the column diameter, the purpose is to strengthen the original column 1 and pier the new column 2, so that the force is more in line with the mechanical principle.

2-3 iron hoops 3 are used to lock and strengthen the pier joint overlap, the purpose is to make the reinforced structure more stable.

working principle:

When carrying out pier connection repairs of damaged ancient buildings, the decayed columns must be dismantled before pier connection to stabilize adjacent beams and beams; secondly, the damaged original column 1 should be excavated and sawed to remove the corresponding part, and then pier connection should be selected according to the remaining part The dovetail mortise and tenon pattern is used as the overlapping part. In order to prevent the sliding and shifting of the pier-connected columns, the dovetail mortise and mortise joints are used. The road iron hoop 3 is reinforced; finally, the overlapping surfaces of the connecting columns must be sawed and chiseled to ensure that the overlapping joints are closely matched.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
