Ancient building beam joint reinforcing and repairing structure

Abstract

The application discloses an ancient building beam joint reinforcing and repairing structure, which comprises two side columns, a bracing strip arranged at the top of the columns, a first tenon arranged at the top of the columns and inserted into the bracing strip, a corridor beam fixed on the two bracing strips, a bracing column inserted at the top of the bracing strip, a rafter inserted at the top of the bracing column, vertical columns tenon-connected between the rafters, and a seat arranged at the bottom of the vertical columns and inserted at the top of the corridor beam. The support of the positioning sleeve is arranged to support the bottom of the side bracing plate, so that the bracing plate is effectively supported in the middle of the corridor beam and assists the support of the corridor beam on the vertical column. The second tenon is arranged to limit the corridor beam from being separated upward from the groove on the bracing strip, and the separation limiting mechanism is used to limit the transverse separation of the bracing strip and the corridor beam. Therefore, after reinforcing and repairing, the connection between the corridor beam and the bracing strip is not easy to be separated, and the stability of the support of the rafter under the two-bridge bracing top method is ensured.

Description

Technical Field

[0001] This invention belongs to the field of ancient building restoration technology, specifically relating to the reinforcement and restoration structure of beam nodes in ancient buildings. Background Technology

[0002] The main structure of the ancient corridor is constructed entirely of wood, with wooden pillars supporting the roof on both sides. The tops of the wooden pillars are joined with wooden support strips by mortise and tenon joints, and the front and rear wooden support strips are glued and fixed by diagonal tenons. The tops of the wooden support strips are fixed to the supporting beams of the corridor roof using a two-bridge support method, as follows: the tops of the support strips are joined with the support pillars by mortise and tenon joints, and the support pillars are joined with the supporting beams by mortise and tenon joints. The supporting beams are fixed together by mortise and tenon joints and secured with wooden dowels. The bottoms of the support pillars are supported by brackets on the corridor beams.

[0003] However, due to the long construction of this type of ancient corridor, the mortise and tenon joints are prone to loosening, especially in the location where the double-bridge support method is used. In addition to supporting the side supports, the corridor beams also provide vertical support for the side beams. Loosening of the mortise and tenon joints can easily cause the connection with the corridor beams to become disconnected. Therefore, a repair structure that can reinforce the beam joints in this location is provided. Summary of the Invention

[0004] The purpose of this invention is to provide a reinforcement and repair structure for the beam joints of ancient buildings, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reinforcement and repair structure for the crossbeam joint of an ancient building, comprising columns on both sides, a support strip set on the top of the columns, a first tenon set on the top of the columns and inserted into the support strip, a corridor crossbeam fixed to the support strips on both sides, a support column inserted into the top of the support strip, a support edge inserted into the top of the support column, a pendant tenoned between the support edges, and a base set at the bottom of the pendant and inserted into the top of the corridor crossbeam.

[0006] The top of the column is provided with a positioning sleeve, and the column, positioning sleeve and support strip are provided with insert strips. The bottom two sides of the corridor beam are provided with stop strips. The stop strips and support strips are laterally inserted with second tenons. The top of the support strip is provided with a limited release mechanism, which is used to limit the lateral separation of the support strip and the corridor beam.

[0007] Preferably, the positioning sleeve is formed by fixing two half-sleeves;

[0008] The two semi-sleeves are fitted with positioning pins on the column, and the two semi-sleeves are both limited by limiting forks at their joints.

[0009] Preferably, the limiting mechanism includes a sleeve plate fitted onto the support column, and pins are vertically inserted into the sleeve plate, the corridor beam, and the support bar.

[0010] Preferably, the positioning sleeve is provided with a side brace, and the top of the side brace is fixed with a support plate, which is supported on the top of the corridor beam.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] After the connector strip is inserted into the connector, it mates with the first tenon inserted into the support strip, achieving a stable installation of the column and the support strip. The positioning sleeve provides support, allowing the side brace to support the bottom of the support plate, effectively supporting the support plate in the middle of the corridor beam and assisting the corridor beam in supporting the vertical column. The second tenon prevents the corridor beam from disengaging upwards from the slot on the support strip, while the detachment limiting mechanism prevents the support strip and corridor beam from disengaging laterally. Therefore, after reinforcement and repair, the connection between the corridor beam and the support strip is less likely to detach, ensuring the stability of the support for the side beam under the two-bridge jacking method.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The structure for reinforcing and repairing the beam joints of ancient buildings includes two columns 1 on both sides, a support strip 2 on top of the column 1, a first tenon 3 on top of the column 1 and inserted into the support strip 2, a corridor beam 4 fixed to the two support strips 2 on both sides, a support column 5 inserted into the top of the support strip 2, a support edge 6 inserted into the top of the support column 5, a pendant 7 tenoned between the support edges 6, and a base 8 set at the bottom of the pendant 7 and slidably inserted into the top of the corridor beam 4.

[0020] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the column 1 is tightly fitted with a positioning sleeve 9. The front and rear parts of the column 1, the positioning sleeve 9 and the support strip 2 are provided with insertion interfaces. Insertion strip 12 is driven into the insertion interface. The insertion strip 12 has a double conical structure. When the insertion interface is inserted into the insertion strip 12, it cooperates with the first tenon 3 to be inserted into the support strip 2, so as to achieve a stable installation of the column 1 and the support strip 2. The bottom sides of the corridor beam 4 are fitted with stop strips 13. The stop strips 13 and the support strip 2 are horizontally driven into the second tenon 14. The setting of the second tenon 14 restricts the corridor beam 4 from disengaging upward from the slot on the support strip 2. The top of the support strip 2 is provided with a limited disengagement mechanism. The limited disengagement mechanism is used to restrict the support strip 2 and the corridor beam 4 from disengaging laterally.

[0021] See Figure 2 and Figure 3 The positioning sleeve 9 is fixed by two semi-shaped sleeves; among them, the two semi-shaped sleeves are connected to the column 1 by positioning pins 10, and both ends of the positioning pins 10 are riveted flat to prevent the positioning pins 10 from disengaging from the column 1 and the semi-shaped sleeves. The forks opened at the edges of the two semi-shaped sleeves are each inserted with a limiting fork 11, which is a U-shaped rod. The setting of the limiting fork 11 helps to prevent the two positioning sleeves 9 from disengaging.

[0022] See Figure 2. Figure 3 and Figure 4 The limiting mechanism includes a sleeve plate 15 that is slidably sleeved on the support column 5, and vertically driven pins 16 on the sleeve plate 15, the corridor beam 4, and the support bar 2.

[0023] Therefore, the setting of the detachment restriction mechanism can effectively prevent the support bar 2 from separating laterally from the corridor beam 4.

[0024] See Figure 2 and Figure 3 The inner half of the positioning sleeve 9 is integrally provided with a side support 17. The top of the side support 17 is pressed and supports the support plate 18, and the support plate 18 is supported on the top of the corridor beam 4.

[0025] The bottom of the support plate 18 is supported by the side brace 17, so that the support plate 18 is effectively supported on the bottom middle side of the corridor beam 4.

[0026] The working principle of this embodiment is as follows:

[0027] After the connector strip 12 is inserted into the connector, it is then inserted into the support strip 2 in conjunction with the first tenon 3, thus achieving a stable installation of the column 1 and the support strip 2.

[0028] The support of the positioning sleeve 9 enables the side brace 17 to support the bottom of the support plate 18, so that the support plate 18 is effectively supported in the middle of the corridor beam 4, and assists the corridor beam 4 in supporting the vertical column 7.

[0029] The second tenon 14 is designed to prevent the corridor beam 4 from disengaging upward from the slot on the support bar 2, while the release mechanism is used to prevent the support bar 2 and the corridor beam 4 from disengaging laterally.

[0030] Therefore, after reinforcement and repair, it can ensure that the connection between the corridor beam 4 and the support strip 2 is not easily disconnected, and ensure the stability of the support for the side 6 under the second bridge support method.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
