Description

Technical Field

[0001] This utility model relates to the field of ancient building restoration technology, specifically to a roof eaves and rafter structure for ancient building restoration. Background Technology

[0002] The eaves rafter is a key component in the roof structure of ancient buildings. Located at the eaves, it directly supports the roof material and transfers the load to the purlins or beams below. The eaves rafter structure is mainly made of wood and is mostly round or square. The diameter or side length is adjusted according to the scale of the building. The common eaves rafter structure is directly installed below the eaves purlin. When in use, a semi-circular groove is carved on the purlin, and the end of the eaves rafter is inserted into it to enhance stability. Wooden or bamboo nails are used to fix the eaves rafter to the purlin.

[0003] For example, Chinese patent CN215254042U, entitled "A Roof Eaves Rafter Structure for Ancient Building Repair," includes two eaves columns and two main columns. Eaves purlins are fixedly connected to the top surfaces of the two eaves columns, and support purlins are fixedly connected to the top surfaces of the two main columns. A plurality of eaves rafters arranged in an array are rotatably connected between the eaves purlins and the support purlins. The top surfaces of both the support purlins and the eaves purlins are provided with a plurality of placement grooves for the eaves rafters to be inserted. A stop block is fixedly connected to one end of each eaves rafter. The top surface of the support purlin is provided with a retaining groove that communicates with the placement groove and is used to accommodate the stop block. The support purlin is provided with a limiting member for restricting the rotation of the eaves rafters. Both ends of the plurality of eaves rafters are provided with insertion grooves, and insertion blocks located in the insertion grooves are inserted into both ends of each eaves rafter. The insertion blocks are slidably connected to the support purlins and the eaves purlins, respectively.

[0004] While the aforementioned existing technologies can enable the use of eaves rafter structures, in practical applications, on the one hand, the fixing effect of the eaves rafters is not good enough. Usually, the eaves rafters are placed in the grooves inside the eaves columns, which makes the eaves rafters prone to swaying on the eaves columns, thus reducing the stability of the roof. On the other hand, it is difficult to adjust the placement position of the eaves rafters. Usually, the grooves are fixed on the main columns, making it difficult to place the eaves rafters in the appropriate position for different situations, thus reducing the practicality of the eaves rafter structure. Therefore, it does not meet the current needs. In response, we propose an eaves rafter structure for the restoration of ancient building roofs. Utility Model Content

[0005] The purpose of this utility model is to provide a method for repairing the roof eaves and rafters of ancient buildings, so as to solve the problems of insufficient fixing effect of the eaves and rafters and the problem of adjusting the placement position of the eaves and rafters mentioned in the background art.

The upper and lower parts of the clamping plates and the interior of the connecting seat are provided with first through holes. The first through holes are through-holes.

[0009] Preferably, a number of second slots are provided both inside the lower part of the eaves column 3 and inside the upper part of the pressure plate. The second slots are through-type structures and correspond to the positions of the first through holes on the clamping plate. Four second insert rods are provided at the front end of the eaves column 3. The second insert rods extend to the rear end of the eaves column 3 through the second slots and the first through holes.

The front and rear ends of the snap-fit ​​rod extend to the outside of the second through hole, and the snap-fit ​​rod is snapped and fixed to the gold pillar.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can fix the eaves rafter body by means of a clamping plate and a pressure plate. When the eaves rafter body is installed, the first insert rod has been inserted into the first slot. At this time, the operator places the pressure plate on the eaves column. The lower end of the eaves column is in contact with the eaves rafter body, and the T-shaped snap-fit ​​plates at both ends of the eaves column are snap-fitted and fixed with the snap-fit ​​groove. Then, the clamping plate is placed into the limiting cavity and adjusted to a suitable position until the clamping plate is in contact with the eaves rafter body. At the same time, the first through hole on the clamping plate corresponds to the position of the second slot. Then, the second insert rod is aligned with the opening of the second slot and inserted into the second slot until the second insert rod passes through the clamping plate through the first through hole, so that the eaves rafter body is fixed on the eaves column, thereby improving the fixing effect of the eaves rafter body.

[0015] (2) This utility model can adjust the eaves rafter body to a suitable position and then fix it through the first slot and the second slot. Before installing the eaves rafter body, adjust the position of the eaves rafter body according to the specific needs. At this time, the operator pushes the eaves rafter body so that one end of the eaves rafter body slides inside the installation cavity. At the same time, the eaves rafter body moves on the eaves column until the eaves rafter body is moved to a suitable position. At this time, the first through hole on the connecting seat corresponds to the position of the first slot. Then, the first insert rod is aligned with the opening of the first slot and pushed into the first slot. The lower end of the first insert rod extends to the bottom of the first slot. Then, the eaves rafter body is fixed in the subsequent way, thereby improving the flexibility of fixing the eaves rafter body in different positions.

[0016] (3) This utility model can limit the lower end of the first insertion rod by means of the snap-fit ​​rod and the second through hole. When the eaves rafter body is installed, the initial fixation of the eaves rafter body has been completed. The operator holds the snap-fit ​​rod and aligns it with the opening of the second through hole. At this time, the operator uses a tool to knock the snap-fit ​​rod into the second through hole until one end of the snap-fit ​​rod penetrates the second through hole and the snap-fit ​​rod is snapped and fixed to the lower end of the gold column, thus completing the fixation of the first insertion rod and improving the firmness of the eaves rafter structure installation.
