Description

TECHNICAL FIELD

[0001] The utility model relates to the field of masonry ancient tower repair and reinforcement, and particularly relates to a fabricated lining outer hoop composite reinforcement device for a masonry ancient tower. BACKGROUND

[0002] Masonry ancient towers are an important component of ancient masonry structures and an important carrier and valuable heritage in the progress of Chinese civilization over thousands of years, and belong to the category of immovable cultural relics buildings. Ancient towers have undergone environmental erosion, and the building materials have deteriorated and the structural performance has significantly decreased, resulting in water seepage in the eaves and finial of the tower, counterflow of water under the tower foundation, local mortar loss and brick collapse, cracking of the door and niche under the combined action of compression and shear, and overall tilting of the tower body.

[0003] Existing tower repair and reinforcement measures mainly include the addition of buttress columns and the laying of cement mortar reinforced mesh to enhance bearing capacity, the addition of structural columns and ring beams to improve overall stability, and seismic isolation and prestressed reinforcement methods for overall seismic reinforcement of masonry ancient towers.

[0004] CN104153596B discloses a method for overall seismic reinforcement of masonry ancient towers, which involves drilling multiple anchor hole through holes in different tower bodies, eaves, and tower foundations, and using cement mortar for post-repairing. This reinforcement method can improve the overall stress and stability of masonry ancient towers, but it is irreversible because of the through holes in the tower body and the use of original materials. At the same time, the direct connection of anchor rods after welding of the steel band hoop may cause excessive local stress in the tower wall, resulting in damage, and the reinforcement effect needs to be discussed.

[0005] CN221219247U discloses a connecting structure for a reinforced concrete ancient tower wall and a brick masonry, which connects the reinforced concrete ancient tower wall and the outer brick masonry by laying connecting pieces and preformed steel bars, effectively enhancing the overall integrity of the connecting part and improving the bearing capacity. However, this method cannot effectively solve the accelerated damage caused by water seepage in the masonry structure, and there is still a risk of local brick collapse.

[0006] Existing masonry structure repair and reinforcement measures are mostly aimed at modern masonry structures, and there are few repair and reinforcement measures for masonry ancient towers. The existing reinforcement measures still have the following defects:

[0007] (1) Ancient tower repair and reinforcement belongs to the category of cultural relics building protection, and the repair and reinforcement concepts such as large-area slotting / digging and replacement of bonding materials do not follow the basic principles of cultural relics building protection, and the reinforcement method has irreversible impact on the ancient tower body.

[0008] (2) Because the ancient tower is a non-movable cultural relic, the existing reinforcement is mostly achieved by intruding the tower body, which is not suitable for demolition and secondary reinforcement, and some methods cause local damage to the ancient tower body.

[0009] (3) The ancient tower is a high-rise unreinforced masonry structure with a large height-width ratio, which is prone to instability and damage under the condition of damage, and further causes continuous collapse. The tower body is in a compression-shear composite stress state, which is prone to form through cracks and overall inclination, and has poor anti-overturning capacity. The existing methods mainly focus on repairing and supporting local cracks, ignoring the overall stress performance of the ancient tower.

[0010] Therefore, under the premise of following the principles of repairing and protecting cultural relics buildings, it is very important to provide a new masonry ancient tower reinforcement method or device to significantly improve the bearing capacity and stability of the ancient tower and long-term protect the existing ancient tower.

[0029] Compared with the prior art, the utility model has the beneficial effects that:

[0030] (1) The ancient tower is not changed. The prestressed assembly type lining outer hoop composite reinforcement brick and stone ancient tower of the utility model occupies small space, the outer hoop assembly is arranged along the eave ring, and is located in the visual blind area. The reinforcement device does not change the appearance and building shape of the ancient tower, and the disturbance to the tower wall will not damage the building materials inside and outside the tower. While eliminating the structural hidden danger, the force transmission path of the original structure is optimized.

[0031] (2) The reinforcement measure is reversible. When the material performance of the ancient tower wall continuously deteriorates or under the action of rare earthquakes, the newly added lining outer hoop assembly can work together with the original structure to form a hoop effect on the original tower wall, avoid forming through cracks through the constraint force, and effectively improve the stability and bearing capacity of the ancient tower.

[0032] (3)The overall stress performance is good. The composite reinforcing device of the inner lining support steel frame and the outer hoop prestressed cable structure not only improves the shear strength of the tower body, but also improves the ultimate compressive strain and compressive strength of the tower body construction material by the constraint effect of the prestressed cable, prolongs the service life of the construction material. The inner lining outer hoop assembly and the prestressed cable form a common stress structure, strengthen the support of the inner lining support steel frame to the inside of the tower body, greatly improve the anti-overturning capacity of the tower body, and then improve the ductility of the tower body. Meanwhile, the modular prefabricated connecting piece effectively transmits the applied prestress to other parts of the structure, ensuring the stability and carrying capacity of the overall structure.

[0033] (4)The assembly adopts a full assembly mode. The parts have high machining precision in the factory, are light and high-strength, are simple and fast to install on the construction site, do not use welding operation, most of the assembly process has been completed during the prefabrication in the factory, and only simple bolt fixing and prestressed cable anchoring are needed during the on-site installation to realize the connection of the inner lining steel frame and the outer hoop assembly. When necessary, it is more convenient to maintain and replace local components, effectively avoiding the increase in cost caused by large-area demolition during later maintenance.

[0048] The following is combined Figures 1-9 This utility model will be described in detail.

[0049] An assembled lining outer hoop composite reinforcing device for masonry ancient tower, comprising a lining support steel frame inside tower wall 1, an inner and outer anchoring assembly and an outer hoop assembly outside tower wall 1, the lining support steel frame comprising a bottom annular clamping plate 501, a vertical support column 502 and an annular support beam 503; the inner and outer anchoring assembly comprising a tower inner anchoring assembly, a tower outer anchoring assembly and a prestressed anchor cable 6031 passing through the tower wall mortar joint, wherein the tower inner anchoring assembly comprises an inner anchor 6011, an outer anchor 6012 and an anchor sleeve 6013, and the tower outer anchoring assembly also comprises an anchor 6016, a short hollow bolt 6014 and a long hollow bolt 6015; the outer hoop assembly comprising a first prefabricated connecting module 6021, a second prefabricated connecting module 6022, a prefabricated sleeve connecting piece 6023, a high-strength bolt 6024, a prestressed steel cable 6032 and a corner rubber pad 6033; the lining support steel frame is connected with the prefabricated connecting module 602 through the prestressed anchor cable 6031 and the anchoring assembly 601.

[0050] As shown in Figure 1 , the outer hoop assembly is arranged above the eave except the first layer which is arranged below the eave, not only maintaining the original features of the ancient tower, but also effectively improving the compressive and shear strength of the tower wall 1 through the lateral restraint provided by the cable system 603 in the outer hoop assembly, delaying the crushing damage process of the mortar masonry material, and further improving the ductility deformation capacity of the tower body. In addition, the closer the component is to the tower fin, the more obvious the effect of reducing the whipping effect caused by the earthquake.

[0051] As shown in Figure 2 and Figure 3 , a 600*500mm slot is first excavated downward in the tower foundation 3, then the annular clamping plate 501 is placed inside it, ensuring that the bottom of the clamping plate remains horizontal, the slot is excavated 50mm inward to the inner wall bottom, and the operating space for the bolt connection between the annular clamping plate 501 and the vertical support column 502 is reserved. The vertical support column 502 is in close contact with the tower inner wall 1, and its top is connected with the annular support beam 503 through high-strength bolts. Subsequently, cast-in-place concrete is cast in the slot in the tower foundation 3, and after solidification, the surface is weathered to maximize the preservation of the original appearance of the tower. The cast-in-place concrete and the annular clamping plate together constitute the bottom ring beam, preventing adverse effects on the ancient tower caused by uneven settlement of the foundation or large vibration loads.

[0052] The vertical support column 502, the annular support beam 503 and the annular clamping plate 501 jointly constitute a spatial steel frame capable of resisting bending and shearing. The vertical support column 502 has the functions of a buttress column and a construction column, and can enhance the integrity and stability of the ancient tower. According to the principle of minimum intervention, a hole is opened in the mortar joint of the tower wall 1 below the tower eave 2. The diameter of the hole is consistent with the length of the mortar joint. The prestressed anchor cable 6031 passes through the hole to connect the inner lining support steel frame and the outer hoop assembly, thereby forming a composite reinforcing device subjected to common force. Mortar and glutinous rice mortar are injected between the mortar joint and the anchor cable 6031 for fixation. The anchoring assembly 601 and the prefabricated connecting module 602 anchor the two ends of the prestressed anchor cable 6031, thereby realizing the connection between the inner lining support steel frame and the outer hoop assembly, forming a hoop effect on the original tower wall 1, and improving the overall stability of the structure. Since the prestressed anchor cable 6031 does not directly contact the bricks of the tower wall 1, local stress concentration of the bricks caused by direct contact under the action of prestress loss or earthquake can be avoided, thereby preventing local bricks from being subjected to compressive shear failure.

[0053] As shown in Figures 4-6 , a corner rubber pad 6033 is additionally arranged at the corner of the outer wall of the ancient tower, which can avoid the direct contact between the corner of the outer hoop prestressed steel cable 6032 and the tower body, disperse the applied pressure, reduce the local pressure, and reduce the risk of surface damage or wear. Meanwhile, a groove is arranged at the center position of the corner rubber pad 6033, which facilitates the fixation of the prestressed steel cable 6032, avoids the displacement or sliding of the cable, reduces the failure risk caused by stress concentration, and good contact condition helps to reduce the loss of prestress.

[0054] The prestressed steel cable 6032 is folded and passes through the connecting buckle on the prefabricated outer sleeve connecting piece 6023, and is fixed by the high-strength bolt 6024 passing through the connecting buckle. The inner support steel frame members are connected in a lap joint manner. The annular clamping plate 501, the annular support beam 503 and the vertical support column 502 are holed at the corresponding positions at both ends, and are fixed by high-strength bolts. The number is determined according to the size and shape of the ancient tower.

[0055] As shown in Figure 7 and Figure 8 , the outer end of the prestressed anchor cable 6031 is first fixed by the anchor device 6016 of the outer anchoring assembly, and then the long hollow bolt 6015 is inserted to be clamped. The diameter of the anchor device is consistent with the inner diameter of the long hollow bolt 6015. The friction and damping force of the inner wall of the long hollow bolt 6015 fix the anchor device 6016, and the long hollow bolt 6015 is fixed with the second prefabricated connecting module 6022 by the surface thread. The inner end of the prestressed anchor cable 6031 is subjected to preliminary tensioning to ensure that the cable is in a slack-free state, and then prestress is gradually applied. After the target prestress value is reached, the anchoring assembly 601 is used for fixation.

[0056] After the anchor cable passes through the anchor sleeve 6013, the inner anchor 6011 is used to fix the cable, and then the outer anchor 6012 is used to anchor in reverse. The diameter of the anchor is smaller than the inner diameter of the anchor sleeve, but larger than the diameter of the bottom hole. The anchor ensures that the prestress applied to the cable will not be lost during installation. At the same time, due to the existence of the anchor sleeve 6013, the anchor cable is prevented from moving due to the action of earthquake or other loads, so as to avoid damage to the anchor and loss of prestress of the cable. The anchoring mode of the reverse double anchor can effectively resist the instability of the anchor cable caused by external loads, and the double anchoring can provide additional anchoring force to provide additional protection for the connection stability of the prestressed anchor cable.

[0057] The inside of the first and second prefabricated connection modules 6021 and 6022 is half reserved with a recess of the size of the short hollow bolt 6014 and the prestressed steel cable 6032 when prefabricated in the factory, so that the short hollow bolt 6014 is embedded in the inside of the first and second prefabricated connection modules 6021 and 6022. After the high-strength bolt 6024 is aligned with the side hole of the first and second prefabricated connection modules 6021 and 6022, the two are fixed. The surface of the prefabricated sleeve connector 6023 is reserved with a hole aligned with the upper and lower reserved holes of the first and second prefabricated connection modules 6021 and 6022, and the deviation is strictly controlled. The high-strength bolt 6024 is used to fix it, and the installation process of the prefabricated connection module 602 is completed.

[0058] The short hollow bolt 6014 is connected with the first and second prefabricated connection modules 6021 and 6022 by the surface thread, and the prestressed steel cable 6032 is placed in the long recess to avoid the slip of the prestressed steel cable 6032 and the loss of prestress of the steel cable under the action of earthquake or other loads. The prestressed steel cable 6032 is fixed by the outer anchor 6012, and prestress is applied to the steel cable before fixation. Finally, the outer anchor 6012 is clamped into the inside of the short hollow bolt 6014. The high-strength bolt 6024 and the prestressed anchor cable 6031 pass through the gap between the two groups of prestressed steel cables 6032, and there is no direct interaction between the components.

[0059] As Figure 8 and Figure 9As shown, when installing the outer hoop assembly, the prestressed steel cable 6032 of the outer wall is first anchored, and the steel cable passes through the gap reserved between the first prefabricated connecting module 6021 and the second prefabricated connecting module 6022, and the two modules are connected and fixed by the high-strength bolt 6024, then the anchored prestressed cable 6031 is clamped into the long hollow bolt 6015. Subsequently, the steel cable in the tower is anchored after prestressing, and the prestressed steel cable 6032 outside the tower is anchored after prestressing, finally the upper and lower holes of the prefabricated outer sleeve connecting piece 6023, the first prefabricated connecting module 6021 and the second prefabricated connecting module 6022 are aligned, and the high-strength bolt 6024 is screwed in to complete the fixation of the prestressed steel cable 6032 outside the tower.

[0060] The components of the present application can be prefabricated in the factory, and only simple assembly and connection are required during on-site construction, which not only greatly improves the installation speed, but also avoids excessive welding operation, and the installation process is simple, and the local component replacement and maintenance in the later period is more convenient, and the life cycle of the structure system is prolonged. Moreover, the composite reinforcing device used in the present application increases the contact area of the anchoring member and the tower wall, avoids the problem of excessive local stress of the wall body, and ensures the anchoring stability of the inner lining and outer hoop device.

[0061] The above specific embodiments are detailed descriptions of the present application, and cannot be considered as limiting the specific embodiments of the present application to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, some simple deductions and substitutions can be made without departing from the concept of the present application, and all of them should be considered as belonging to the protection scope of the present application.
