Description

Technical Field

[0001] This utility model relates to the field of dougong (bracket set) repair, and in particular to a dougong seismic reinforcement connection. Background Technology

[0002] Dou-gong is a unique structural feature of Chinese architecture. At the junction of columns and beams, layers of arch-shaped load-bearing structures are added from the top of the column, called arches. The square wooden blocks placed between the arches are called dou, and together they are called dou-gong. Dou-gong provides strong earthquake resistance to buildings.

[0003] The dougong is a large timber component in ancient architecture, also known as a dadou, and was called loudou before the Song Dynasty. It is the lowest supporting component in the dougong assembly, and is generally used above the center line of the column. The lougong has a cross opening to hold the front, back and left and right arches.

[0004] If cracks appear in the bracket set (dougong), and are not repaired promptly, they will affect the stability of the building, potentially causing the bracket set to break and the building to collapse during an earthquake. Traditionally, when repairing ancient buildings, the bracket sets in the bracket structure are mostly replaced with new ones. However, this often results in a noticeable color difference between the replaced bracket sets and the original bracket set, failing to achieve the goal of restoring the building to its original state. To address these shortcomings, we propose a seismic-resistant reinforcement connection method for the bracket set. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a seismic-resistant reinforcement connector for dougong (bracket set).

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a dougong (bracket set) seismic reinforcement connector, comprising:

[0007] The bracket body is composed of a square block, with a cross groove on the upper surface of the square block for the bracket to be inserted, and a pin hole on the lower surface of the square block for the column to be inserted. The cross groove divides the upper surface of the square block into four protruding blocks.

[0008] The reinforcement structure consists of a bottom reinforcement structure for the square block, a protruding block reinforcement structure, and an end face reinforcement structure for the square block.

[0009] The square block end face reinforcement structure includes a reinforcement plate, dovetail pins fixedly installed on the front and back of the reinforcement plate, a clearance groove opened in the bottom wall of the cross groove, a dovetail groove opened in the inner wall of the clearance groove, and an assembly assembly disposed between the reinforcement plate and the clearance groove.

[0010] Preferably, the assembly includes a pin groove formed on the surface of the reinforcing plate and the inner wall of the clearance groove, and a pin inserted into the inner wall of the pin groove.

[0011] Preferably, the bottom reinforcement structure includes a reinforcement ring, a groove formed at the bottom of the square block, an insertion groove formed on the inner wall of the reinforcement ring, and a connecting pin fixedly installed at the upper end of the reinforcement ring.

[0012] Preferably, the inner top wall of the groove has a connecting hole for inserting a connecting pin.

[0013] Preferably, the inner diameter of the insertion groove is adapted to the inner diameter of the pin hole.

[0014] Preferably, the protrusion reinforcement structure includes a through groove formed in the inner wall of the dovetail groove, insertion holes formed on the lower surface of the protrusion and the upper surface of the square block, and a pin that can be inserted into the inner wall of the insertion hole.

[0015] Preferably, the through groove can separate the protruding block and the square block into two parts.

[0016] Preferably, there are multiple connecting pins arranged in a circumferential array on the upper surface of the reinforcing ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a square block end face reinforcement structure, when cracks occur in the bottom wall of the cross groove, firstly, a clearance groove is opened in the inner bottom wall of the cross groove, then a dovetail groove is opened in the inner wall of the clearance groove. After that, the reinforcement plate can be inserted into the clearance groove, and the dovetail pin will be inserted into the dovetail groove. Thus, the square blocks on both sides of the cross groove can be connected into one piece by using the reinforcement plate, thereby improving the strength of the square blocks. Moreover, the dougong body can be reinforced without replacing the dougong body or changing the appearance of the dougong body, thus achieving restoration to its original state and improving the earthquake resistance of the dougong and the building.

[0019] 2. By setting up a bottom reinforcement structure for the square block, firstly, a groove that matches the reinforcement ring is opened on the bottom of the square block, then a connecting hole is opened on the inner wall of the groove, and then the connecting pin is inserted into the connecting hole, so that the bottom of the square block and the reinforcement ring can be assembled into one piece, thereby enhancing the strength of the bottom of the square block.

[0020] 3. By setting up a reinforced structure with raised blocks, when cracks occur between the raised blocks and the cross groove, a through groove can be opened in the dovetail groove to separate the raised blocks and the square blocks into two parts. Then, insertion holes can be opened on the opposite sides of the raised blocks and the square blocks respectively. Then, pins can be inserted into the insertion holes on the raised blocks and the square blocks respectively, so that the raised blocks and the square blocks can be assembled into one piece, thereby improving the strength between the raised blocks and the square blocks.

[0033] When a crack appears in the inner bottom wall 11 of the cross groove, firstly, a relief groove 22 is opened in the inner bottom wall of the cross groove 11, then a dovetail groove 23 is opened in the inner wall of the relief groove 22, and pin grooves 30 are opened in both the inner wall of the relief groove 22 and the surface of the reinforcing plate 20. Then, the reinforcing plate 20 can be inserted into the relief groove 22, and the dovetail pin 21 will be inserted into the dovetail groove 23. Then, the pin 31 is inserted into the pin groove 30 to fix the reinforcing plate 20. Thus, the square blocks 10 on both sides of the cross groove 11 can be connected into one piece by the reinforcing plate 20, thereby improving the strength of the square blocks 10.
