[0002] Brick arch is a traditional and ancient building structure. This type of structure is a masonry method that uses the lateral pressure between bricks to build a span-bearing structure. By arranging a reasonable spatial form and span-rise ratio, the internal force characteristics of the arch structure are optimized to avoid bending moment and tensile stress in the arch body, and the strong compressive resistance of bricks can be fully utilized. In addition, this type of structure is also fireproof, durable, and beautiful in appearance. It has been widely used in ancient and modern times, both at home and abroad. For ancient brick arch structures that have been baptized by time, due to the influence of complex adverse external forces (earthquakes, load changes, weathering, etc.), the arch body often shows structural cracks with a certain extension length, deformation of the arch axis, and the arch construction material bricks and mortar joint materials are calcined and powdered, and the mechanical strength is reduced.

[0033] Embodiment 1 of the utility model of ancient building brick vault reinforcement and repair structure
[0034] Please refer to Figure 1The utility model discloses an ancient building brick vault reinforcement and repair structure, comprising two ancient building walls 9, a brick arch vault 1 is arranged between the tops of the two ancient building walls 9, and the tops of the two ancient building walls 9 are both provided with restraints, the brick arch vault 1 is located between the two restraints, and the top of the brick arch vault 1 is also provided with a reinforcement member located between the two restraints. The restraints set by the present application are used to provide reverse thrust for the brick arch vault 1, restrain the horizontal displacement of the brick arch vault 1, and the brick arch vault 1 can be reinforced and protected by the arch plate 3. The brick arch vault 1 will produce cracks 10 after the baptism of time, and the generation of the cracks 10 affects the overall stability of the brick arch vault 1. The present application can, under the premise of not destroying the overall structure of the brick arch vault 1, comprehensively consider the structural force characteristics of the brick arch vault 1, and effectively suppress the deformation and instability trend of the brick arch vault 1 through controllable limited degree of concealed intervention measures, thereby ensuring the permanent stability of the cultural relic building and facilitating the inheritance, protection and utilization of the cultural heritage.
[0035] Further, such as Figure 1 As shown, the restraining member is an arch foot reinforcement beam 2, which is cast on the top of the ancient building wall 9, and the arch foot reinforcement beam 2 is in contact with the end of the brick arch 1. The arch foot reinforcement beam 2 is cast with reinforced concrete.
[0036] Further, such as Figure 1 As shown, the arch foot reinforcement beam 2 is arranged along the entire length of the brick arch 1. The arch foot reinforcement beam 2 is used to provide a reverse thrust for the brick arch 1, constrain the horizontal displacement of the brick arch 1, effectively suppress the deformation and instability trend of the brick arch 1, ensure the permanent stability of the cultural relic building, and facilitate the inheritance, protection and utilization of the cultural heritage.

[0043] The utility model further provides a reinforcement and repair structure for ancient building brick vaults, such as Figure 4 As shown, a number of lifting rods are provided between the reinforcement mesh and the arch plate 3. The lifting rods are arranged radially along the brick arch 1 and are used to transfer the load of the brick arch 1 to the arch plate 3, and evenly distribute the load of the brick arch 1 to the arch plate 3, thereby further improving the bearing capacity and stability of the ancient building.
[0044] Further, such as Figure 4 As shown, the lifting rod includes a stainless steel rod body 6 connected to the reinforcement mesh. The stainless steel rod body 6 passes through the brick arch 1, the rock wool isolation layer 4 and the arch plate 3 and is threadedly connected with a stainless steel nut 11. The stainless steel rod body 6 is provided with a thread adapted to the stainless steel nut 11.
[0045] Further, such as Figure 4 As shown, the outer surface of the stainless steel rod body 6 is sleeved with a stainless steel spring 5 and two stainless steel washers 12 located on the side of the arch plate 3 away from the brick arch 1. The stainless steel spring 5 is located between the two stainless steel washers 12. The sides of the two stainless steel washers 12 away from each other are in contact with the stainless steel nut 11 and the arch plate 3 respectively. The stainless steel spring 5 provides appropriate upward support for the brick arch 1 and can also adaptively adjust the force applied to the brick arch 1 according to the temperature difference.
[0046] When in use, a temporary support is first implemented at the bottom of the brick arch 1 where there is a risk of instability to ensure that the brick arch 1 itself is stable during the reinforcement and repair process; in addition, the mortar joints of part of the arch bottom are removed and the brick edges of the arch bottom bricks 13 are ground to a certain width, so as to form a caulking groove with a depth of 3-4cm and a width of 10-12mm between the mortar joints and the arch bottom bricks 13; according to the arrangement spacing of the stainless steel rod body 6, an upward drilling is performed at the brick joint between the two arch bottom bricks 13 to penetrate the entire brick arch 1, so as to form a through-hole for the stainless steel rod body 6 to be installed;
[0047] Use reinforced concrete to cast the arch foot reinforcement beam 2. The two ends of the arch foot reinforcement beam 2 are constrained by other auxiliary facilities according to the ancient building structure. The arch foot reinforcement beam 2 can balance the horizontal thrust of the brick arch voucher 1 at the arch foot to ensure the stability of the brick arch voucher 1.
[0048] The arch foot reinforcement beam 2 and the arch plate 3 are simultaneously tied with steel bars and poured with concrete, and the two form an integral structure. The arch plate 3 is a reinforced concrete arched plate shell structure attached and poured on the top of the brick arch voucher 1 according to the shape of the brick arch voucher 1. Both ends of the arch plate 3 are supported on the arch foot reinforcement beam 2. The arch plate 3 and the brick arch voucher 1 are separated and isolated by a rock wool isolation layer 4. Before pouring concrete, PVC pipes are pre-buried according to the arrangement spacing of the stainless steel rod body 6 to form a through-hole for the stainless steel rod body 6 to install;
[0049] When the arch foot reinforcement beam 2 and the arch plate 3 reach a predetermined strength, the longitudinal mesh monofilament 7 and the transverse mesh monofilament 8 are installed at the mortar joint at the bottom of the brick arch 1. The longitudinal mesh monofilament 7 is buried along the straight caulking groove along the depth direction of the brick arch 1, and the transverse mesh monofilament 8 is buried along the serrated caulking groove along the arc direction of the brick arch 1. The two are connected by welding, and the caulking groove is filled and compacted with mortar paste to form a heavy hook mortar joint 14 to conceal the reinforcement mesh. The stainless steel rod body 6 passes through the installation holes reserved on the brick arch 1 and the arch plate 3. The stainless steel rod body 6 is welded with the longitudinal mesh monofilament 7 or the transverse mesh monofilament 8, and the top is anchored on the arch plate 3 by sequentially wearing a stainless steel nut 11, a stainless steel spring 5 and a stainless steel gasket 12. The stainless steel spring 5 provides appropriate upward support for the brick arch 1, and can also adaptively adjust the force applied to the brick arch 1 according to the temperature difference to avoid the uncoordinated deformation between the two due to temperature changes.
