DETAILED DESCRIPTION

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0043] like Figures 1 to 11 As shown, the present invention provides an energy-dissipating connection structure and an assembled concrete shear wall device.

[0044] An energy-absorbing connection structure comprises a first energy-absorbing part, a second energy-absorbing part, a first fixing part and a second fixing part; when the first energy-absorbing part is subjected to a load in a first direction, the first energy-absorbing part is deformed to consume the energy of the load in the first direction; when the second energy-absorbing part is subjected to a load in a second direction, the second energy-absorbing part is deformed to consume the energy of the load in the second direction; wherein the first direction and the second direction are perpendicular to each other, and the first energy-absorbing part and the second energy-absorbing part are arranged along the second direction.

[0045] The first fixing part is detachably connected to the first energy consuming part, the first fixing part is used to control the deformation of the first energy consuming part along the first direction, and the first fixing part is detachably connected to the external connecting body; the second fixing part is detachably connected to the second energy consuming part, the second fixing part is used to control the deformation of the second energy consuming part along the second direction, and the second fixing part is detachably connected to the external connecting body.

[0046] The first energy consuming part and the second energy consuming part in the present invention consume the load energy in the first direction and the second direction by deforming in the first direction and the second direction, thereby realizing energy consumption. The present invention prevents the external connector from being damaged by the load through the deformation of the first energy consuming part and the second energy consuming part.

[0047] The present invention controls the first energy consuming part to deform along the first direction through the first fixing part, and controls the second energy consuming part to deform along the second direction through the second fixing part, so as to prevent the first energy consuming part and the second energy consuming part from deforming under no external load and ensure the normal operation of the external connector.

[0048] The present invention uses a detachable connection between the first fixing part and the first energy consuming part, the second fixing part and the second energy consuming part, the first fixing part and the external connecting body, and the second fixing part and the external connecting body. When the first energy consuming part and / or the second energy consuming part is severely damaged, the first energy consuming part and / or the second energy consuming part can be replaced to restore the use function of the external connecting body.

[0049] In this embodiment, the first energy-consuming part and the second energy-consuming part are both formed by a special structure of the energy-consuming plate 101 and the deformable part 202, so that the stiffness of different positions is different, resulting in a stiffness difference. When a load is applied to them, due to the existence of the stiffness difference, the energy-consuming plate 101 and the deformable part 202 are deformed to consume the load energy. Of course, the first energy-consuming part and the second energy-consuming part can also be elastic parts of normal structure. When a load is applied to them, the entire energy-consuming part is deformed. Later, under the action of elasticity, the deformation disappears, and energy is consumed in this process. Of course, the energy-consuming part can also be a plastic part of normal structure or an elastic part of special structure, etc., as long as the load energy it receives is consumed through deformation.

[0050] like Figure 2-Figure 3 As shown, this embodiment discloses a first buckling energy dissipation connection assembly, which includes a first energy dissipation portion and a first fixing portion; the first energy dissipation portion is an energy dissipation plate 101, and the energy dissipation plate 101 is provided with buckling grooves 102 on both sides of the second direction, and the buckling grooves 102 are used to reduce the stiffness of the deformation area of ​​the energy dissipation plate 101; the first fixing portion includes a first constraint plate 103 and a second constraint plate 110 arranged in parallel and at intervals, and the energy dissipation plate 101 is arranged between the first constraint plate 103 and the second constraint plate 110 and is detachably connected thereto.

[0051] Since the energy dissipation plate 101 is provided with buckling grooves 102 on both sides of the second direction, the width of the deformation area of ​​the energy dissipation plate 101 between the two buckling grooves 102 is significantly smaller than the width of other areas, which makes the stiffness of the energy dissipation plate 101 in the deformation area smaller than the stiffness of other areas; when the energy dissipation plate 101 is subjected to an external load in the first direction, the energy dissipation plate 101 buckles and deforms in the deformation area, thereby consuming the load energy received by itself and realizing energy dissipation. The first constraint plate 103 and the second constraint plate 110 in the first fixing part constrain the energy dissipation plate 101 to deform only along the first direction. The first constraint plate 103 and the second constraint plate 110 provide out-of-plane constraints for the energy dissipation plate 101 and cause multi-order buckling, thereby effectively improving its compressive bearing capacity.

[0052] Preferably, one end of the energy consuming plate 101 in the first direction is fixedly connected to the energy consuming end plate 104, and the other end of the energy consuming plate 101 in the first direction is detachably connected to the first constraint plate 103 and the second constraint plate 110; the other end of the first constraint plate 103 and the second constraint plate 110 in the first direction is fixedly connected to the constraint end plate 105.

[0053] The energy-dissipating end plate 104 and the restraining end plate 105 are both detachably connected to the external connector, and the energy-dissipating end plate 104 and the restraining end plate 105 are used to apply a first direction load to the energy-dissipating plate 101 .

[0054] First, the energy-absorbing end plate 104 and the constraint end plate 105 are both detachably connected to the external connector. When the external connector is subjected to a load, the energy-absorbing end plate 104 and the constraint end plate 105 transfer the load and apply it to the energy-absorbing plate 101. The energy-absorbing plate 101 bends and deforms, thereby consuming the load energy it is subjected to and achieving energy consumption, thereby protecting the external connector from the influence of the load and enabling it to be used normally later.

[0055] Secondly, when the external load is large or the destructive force is strong, the energy dissipation plate 101 undergoes large deformation and suffers great damage. The energy dissipation end plate 104, the constraint end plate 105 and the external connector are disassembled, and the disassembled first buckling energy dissipation connection assembly 1 is further disassembled. The energy dissipation plate 101, the first constraint plate 103 and the second constraint plate 110 are separated, and a new energy dissipation plate 101 is replaced, and a new first buckling energy dissipation connection assembly is assembled and installed on the external connector to restore the external connector to its use function. In this embodiment, the energy dissipation end plate 104 and the energy dissipation plate 101 are an integrated structure. When the energy dissipation plate 101 is replaced, the energy dissipation end plate 104 needs to be replaced together.

[0056] Of course, the end of the energy dissipation plate 101 close to the external connector can be directly detachably connected thereto, or other intermediate connectors can be selected to connect the energy dissipation plate 101 to the external connector, such as a T-shaped plate, etc. The ends of the first constraint plate 103 and the second constraint plate 110 close to the external connector can also be directly detachably connected thereto, or other intermediate connectors can be selected to connect the first constraint plate 103 and the second constraint plate 110 to the external connector, respectively.

[0057] Preferably, the energy-absorbing end plate 104 and the restraining end plate 105 are arranged perpendicular to the energy-absorbing plate 101. The energy-absorbing end plate 104 and the restraining end plate 105 can better bear the load force and apply the load force to the energy-absorbing plate 101, that is, better transfer the load received and apply it to the energy-absorbing plate 101, and the energy-absorbing plate 101 bends and deforms, thereby consuming energy to the maximum extent and ensuring the safety of the external connecting parts.

[0058] Preferably, the energy dissipation plate 101 is arranged with the same width as the first constraint plate 103 and the second constraint plate 110, and one end of the energy dissipation plate 101 is inserted into one side of the first constraint plate 103 and the second constraint plate 110, so that one side of the energy dissipation plate 101 overlaps with the first constraint plate 103 and the second constraint plate 110, and the first constraint plate 103 and the second constraint plate 110 cover the entire area of ​​the buckling groove 102. When the energy dissipation plate 101 is deformed, the first constraint plate 103 and the second constraint plate 110 limit the out-of-plane displacement of the energy dissipation plate 101, that is, the deformation displacement of the energy dissipation plate 101 can only occur between the first constraint plate 103 and the second constraint plate 110. At the same time, there is a certain space between the side of the first constraint plate 103 and the second constraint plate 110 close to the energy dissipation end plate 104 and the energy dissipation end plate 104, so as to ensure that the energy dissipation plate 101 can be displaced between the first constraint plate 103 and the second constraint plate 110 when the energy dissipation plate 101 is deformed.

[0059] According to a further optimization scheme, an oblong hole 106 is provided on the energy dissipation plate 101, and the oblong hole 106 is arranged along the first direction. A sliding rod 107 is slidably provided in the oblong hole 106, and both ends of the sliding rod 107 are detachably connected to the first constraint plate 103 and the second constraint plate 110 respectively.

[0060] When the external connector is subjected to a load in the first direction, the load is transmitted to the energy dissipation plate 101 through the energy dissipation end plate 104 and the constraint end plate 105, and since the first constraint plate 103 and the second constraint plate 110 limit the out-of-plane displacement of the energy dissipation plate 101, that is, the deformation displacement of the energy dissipation plate 101 can only occur between the first constraint plate 103 and the second constraint plate 110, the load acts on the energy dissipation plate 101, and since the sliding rod 107 is detachably connected to the first constraint plate 103 and the second constraint plate 110, When the energy dissipation plate 101 is deformed, since the oblong hole 106 is arranged along the first direction, the sliding rod 107 is slidably set in the oblong hole 106. When the energy dissipation plate 101 is deformed and displaced, it can only be displaced along its height direction by the restriction generated by the sliding rod 107 and the oblong hole 106. The oblong hole 106 is used to limit the movement of the energy dissipation plate 101 in the first direction, which means that the energy dissipation plate 101 can move within the length range of the oblong hole 106 under the action of the load in the first direction, and will not exceed this range.

[0061] Preferably, the buckling groove 102 is arranged in the middle of both sides of the energy absorbing plate 101, the oblong hole 106 is arranged on the side of the energy absorbing plate 101 close to the energy absorbing end plate 104, and the energy absorbing plate 101 is provided with an ordinary circular hole on the side away from the energy absorbing end plate 104, and the oblong hole 106 and the ordinary circular hole are respectively arranged on the upper and lower sides of the buckling groove 102; the first constraint plate 103 and the second constraint plate 110 are provided with ordinary circular holes at positions opposite to the oblong hole 106, the buckling groove 102 and the ordinary circular hole on the energy absorbing plate 101, and bolts are passed through the corresponding holes, and the first constraint plate 103, the second constraint plate 110 and the energy absorbing plate 101 are detachably connected by bolts, and the sliding rod 107 mentioned above is also preferably a bolt.

[0062] Among them, the energy dissipation plate 101 is provided with gaskets 109 on both sides of the ordinary circular hole and the oblong hole, and a gasket 108 is provided in the buckling groove 102. The gasket 108 is in conflict with the first constraint plate 103 and the second constraint plate 110. The gasket 109 and the gasket 108 ensure that the constraint plate and the energy dissipation plate 101 are in conflict with each other. When the outside is subjected to a load in the first direction, the gasket 109 and the gasket 108 are used to ensure uniform force between the first constraint plate 103, the second constraint plate 110 and the energy dissipation plate 101.

[0063] like Figure 4-Figure 5 As shown, this embodiment discloses a second buckling energy dissipation connection assembly, which includes a second energy dissipation portion and a second fixed portion; the second energy dissipation portion includes a first fixed plate 201, a second fixed plate 203, and a plurality of deformable members 202 fixedly arranged between the first fixed plate 201 and the second fixed plate 203, the cross-sectional areas at both ends of the deformable members 202 are larger than the middle cross-sectional area, the plurality of deformable members 202 are arranged at intervals, and the first fixed plate 201 and the second fixed plate 203 are respectively detachably connected to the second fixed portion.

[0064] Since the cross-sectional areas at both ends of the deformable member 202 are larger than the middle cross-sectional area, the middle stiffness of the deformable member 202 is smaller than the stiffness at both ends. This causes the middle region of the deformable member 202 to bend and deform when the deformable member 202 is subjected to an external load in the second direction, thereby consuming the load energy received by itself and achieving energy dissipation. In addition, the deformable member 202 in the present application is provided with multiple ones, thereby improving the bearing capacity and energy dissipation capacity of the second energy-consuming part, effectively reducing damage to the deformable member 202, and reducing the number of times the deformable member 202 is replaced.

[0065] The specific dimensions of the deformable member 202 in this embodiment are as follows: Figure 5As shown, the entire component is 460 mm long and 460 mm high, the first fixed plate 201 is 80 mm wide, the first fixed plate 201 is 15 mm thick, the upper and lower ends of the deformable member 202 are 60 mm wide, and the middle part of the deformable member 202 is 20 mm wide. It should be noted that this size is used as the standard in the present invention, and this type of deformable member 202 can be set with deformable members 202 of different sizes according to different construction conditions.

[0066] Preferably, the deformable member 202 and the energy dissipation plate 101 are arranged at the same height, so that when the external connection member is subjected to a load, the two can jointly consume the load energy and work simultaneously to prevent the load energy from being concentrated in a certain component and accelerating the damage of the component.

[0067] Preferably, the second fixing portion includes a fixed limiting element, which is detachably connected to the first fixing plate 201 and the second fixing plate 203, and is used to limit deformation of the first fixing plate 201 and the second fixing plate 203, and is detachably connected to the external connecting piece.

[0068] First, the fixed limiting element is detachably connected to the first fixed plate 201 and the second fixed plate 203. When the external connecting body receives a load in the second direction, the fixed limiting element transfers the load in the second direction and applies it to the deformable member 202. The deformable member 202 bends and deforms, thereby consuming the load energy received by itself and achieving energy dissipation, thereby protecting the external connecting body from the influence of the load and allowing it to be used normally afterwards.

[0069] Secondly, when the external load in the second direction is large or the destructive force is strong, the deformation of the deformable member 202 is large, and the deformable member 202 itself is greatly damaged. The fixed limiting element and the external connector are disassembled, and the disassembled second buckling energy dissipation connection assembly is further disassembled, and the deformable member 202 and the fixed limiting element are separated, and a new deformable member 202 is replaced, and a new second buckling energy dissipation connection assembly is assembled and installed on the external connector to restore the external connector to its use function. In this embodiment, the deformable member 202 and the first fixing plate 201 and the second fixing plate 203 are an integrated structure. When replacing the deformable member 202, the first fixing plate 201 and the second fixing plate 203 need to be replaced together.

[0070] Again, the fixed limiting element limits the deformation of the first fixing plate 201 and the second fixing plate 203, ensuring that the second energy consuming part can only be deformed in the deformable member 202, ensuring the connection strength between the fixed limiting element and the first fixing plate 201 and the second fixing plate 203 respectively, and after the deformable member 202 is deformed in the later stage, it is ensured that the second energy consuming part can be disassembled and separated from the second fixing part, so as to facilitate replacement with a new one and avoid the technical problem that the first fixing plate 201 and the second fixing plate 203 cannot be disassembled due to deformation.

[0071] A further optimized solution is provided, in which the fixed limiting element includes a first fixed angle steel 207 and a second fixed angle steel 208, which are arranged on both sides of the first fixed plate 201 and the second fixed plate 203 and are detachably connected thereto, and an anchor plate 204 is arranged on one side of the first fixed angle steel 207 and the second fixed angle steel 208 close to the external connector, and the anchor plate 204 is detachably connected to the first fixed angle steel 207 and the second fixed angle steel 208, respectively, and the anchor plate 204 is connected to the external connector.

[0072] The first fixed angle steel 207 and the second fixed angle steel 208 clamp and fix the first fixed plate 201, and the first fixed angle steel 207 and the second fixed angle steel 208 clamp and fix the second fixed plate 203. The rigidity of the first fixed angle steel 207 and the second fixed angle steel 208 is used to improve the rigidity of the first fixed plate 201 and the second fixed plate 203 to prevent them from deforming when the deformable member 202 is deformed; at the same time, the anchor plate 204 is detachably connected to the first fixed angle steel 207 and the second fixed angle steel 208 respectively, further preventing the first fixed plate 201 and the second fixed plate 203 from deforming; the anchor plate 204 is connected to the external connector, and while the anchor plate 204 bears the second direction load on the external connector, the second direction load is transferred to the deformable member 202 through the first fixed angle steel 207 and the second fixed angle steel 208 and the first fixed plate 201 and the second fixed plate 203.

[0073] Preferably, the anchor plate 204 is arranged perpendicular to the deformable member 202. The anchor plate 204 can better bear the second direction load borne by the external connecting member and transfer the load in this direction to the deformable member 202, that is, better transfer and apply the second direction load to the deformable member 202, so that the deformable member 202 bends and deforms, thereby consuming energy to the maximum extent and ensuring the safety of the external connecting member.

[0074] The first fixed angle steel 207, the second fixed angle steel 208 and the first fixed plate 201 are detachably connected by bolts and nuts, the first fixed angle steel 207, the second fixed angle steel 208 and the second fixed plate 203 are detachably connected by bolts and nuts, the first fixed angle steel 207 and the anchor plate 204 are detachably connected by bolts and nuts, and the second fixed angle steel 208 and the anchor plate 204 are detachably connected by bolts and nuts. Of course, the present application can also realize detachable connection by various methods such as plug-in and snap-in. For example, a snap-in column is fixedly provided on one side of the first fixed plate 201 close to the first fixed angle steel 207, and a snap-in hole matching the snap-in column is opened on the first fixed angle steel 207. The other end of the snap-in column is fixed and limited by a nut or other fastener to realize the detachable connection between the first fixed plate 201 and the first fixed angle steel 207. Other detachable connections can also be realized by this method, or other methods can be selected to realize detachable connection.

[0075] A prefabricated concrete shear wall device comprises the above-mentioned energy dissipation connection structure, a prefabricated concrete wall and a concrete layer 5, wherein the prefabricated concrete wall is arranged along a first direction, and a first fixing portion and a second fixing portion are both detachably connected to the prefabricated concrete wall; the concrete layer 5 is fixedly arranged between two adjacent groups of prefabricated walls above and below.

[0076] In this embodiment, the first direction is the vertical direction, and the second direction is the horizontal direction, that is, the assembled concrete walls are arranged up and down, as shown in FIG. Figure 1 The one-to-one arrangement described in the above may also be an upper and lower staggered arrangement, that is, one prefabricated concrete wall arranged at the top corresponds to two prefabricated concrete walls arranged at the bottom, or two prefabricated concrete walls arranged at the top correspond to one prefabricated concrete wall arranged at the bottom.

[0077] The energy-dissipating connection structure is arranged between the upper and lower assembled concrete walls, and the energy-dissipating connection structure connects the upper and lower assembled concrete walls through the first fixing part and the second fixing part. When the assembled concrete wall is subjected to loads in the first direction and the second direction, the first energy-dissipating part and the second energy-dissipating part deform in the first direction and the second direction to consume the load energy in the first direction and the second direction, thereby achieving energy dissipation. The present invention prevents the assembled concrete wall from being damaged by the load through the deformation of the first energy-dissipating part and the second energy-dissipating part.

[0078] The concrete layer 5 is fixedly arranged between the two adjacent groups of prefabricated concrete walls. The concrete layer 5 has compressive strength, which enables it to withstand greater loads and shear forces, significantly improves the bearing capacity and overall stability of the prefabricated shear wall, and can absorb a large amount of energy during the stress process.

[0079] A further optimized solution is that several groups of load transfer elements are fixedly arranged inside the prefabricated wall, and the load transfer elements are detachably connected to the first fixing part and the second fixing part; some load transfer elements in the two adjacent groups of prefabricated concrete walls are inserted into the concrete layer, and the two load transfer elements are overlapped. The load transfer elements and the concrete layer 5 organically fix and connect the prefabricated concrete walls arranged up and down, thereby improving the bearing capacity and overall stability of the entire shear wall. At the same time, the load transfer elements are detachably connected to the first fixing part and the second fixing part, and the prefabricated concrete walls arranged up and down, the first energy absorbing part and the first fixing part are organically connected by the load transfer elements, and the prefabricated concrete walls arranged up and down, the second energy absorbing part and the second fixing part are organically connected by the load transfer elements. Preferably, the load transfer elements can be longitudinal bars, reinforcing bars, etc., which can be selected according to needs.

[0080] A further optimized solution is that a pre-embedded single-sided sleeve 205 and a pre-embedded mechanical sleeve 206 are fixedly provided on one side of the anchor plate 204 close to the prefabricated concrete wall, and the pre-embedded single-sided sleeve 205 and the pre-embedded mechanical sleeve 206 are arranged in the prefabricated concrete wall; the pre-embedded mechanical sleeve 206 is connected to the load transfer element, and the pre-embedded single-sided sleeve 205 and the pre-embedded mechanical sleeve 206 are both detachably connected to the fixed limiting element. The embedded single-sided sleeve 205 and the embedded mechanical sleeve 206 are fixedly connected to the anchor plate 204 by welding. When the prefabricated concrete wall is manufactured, the embedded mechanical sleeve 206 is first connected to the load transfer element, and then the anchor plate 204, the embedded single-sided sleeve 205 and the embedded mechanical sleeve 206 are embedded in the prefabricated concrete wall, so that the anchor plate 204, the embedded single-sided sleeve 205, the embedded mechanical sleeve 206 and the prefabricated concrete wall form an integrated structure, and then the first prefabricated concrete wall 3 and the second prefabricated concrete wall 4 are cast. The cast anchor plate 204 can be directly and detachably connected to the fixed limiting element, which is convenient for later installation.

[0081] like Figure 1 The present invention describes a prefabricated concrete shear wall device with a specific scheme. The prefabricated concrete shear wall device includes a first prefabricated concrete wall 3 and a second prefabricated concrete wall 4 arranged one by one in the upper and lower parts. The energy dissipation connection structure includes a first buckling energy dissipation connection component 1, a concrete layer 5, and a second buckling energy dissipation connection component 2. The first buckling energy dissipation connection component 1 and the second buckling energy dissipation connection component 2 are each provided with two groups, and the concrete layer 5 is provided with three groups. The three are arranged in sequence along the horizontal direction, that is, in the order of the first buckling energy dissipation connection component 1, the concrete layer 5, the second buckling energy dissipation connection component 2, the concrete layer 5, the second buckling energy dissipation connection component 2, the concrete layer 5 and the first buckling energy dissipation connection component 1.

[0082] The load transfer elements inside the first prefabricated concrete wall 3 include the first end longitudinal reinforcement 301, the first lap longitudinal reinforcement 302 and the first middle longitudinal reinforcement 303, and the load transfer elements inside the second prefabricated concrete wall 4 include the second end longitudinal reinforcement 401, the second lap longitudinal reinforcement 402 and the second middle longitudinal reinforcement 403; the first end longitudinal reinforcement 301 is arranged on both sides of the first prefabricated concrete wall 3 in the horizontal direction, and the second end longitudinal reinforcement 401 is arranged on both sides of the second prefabricated concrete wall 4 in the horizontal direction, the end of the first end longitudinal reinforcement 301 passes through the energy-absorbing end plate 104 and is fixed by a nut, the end of the second end longitudinal reinforcement 401 passes through the constraint end plate 105 and is fixed by a nut, the end of the first end longitudinal reinforcement 301 and the end of the second end longitudinal reinforcement 401 are both threaded, and the thread of the end of the longitudinal reinforcement is threadedly connected with the nut to achieve a detachable connection. The energy-absorbing plate 101, the first constraint plate 103 and the second constraint plate 110 are in the same plane as the first prefabricated concrete wall 3 and the second prefabricated concrete wall 4.

[0083] One end of the first lap longitudinal reinforcement 302 is arranged in the first prefabricated concrete wall 3 and fixedly connected thereto, and the other end of the first lap longitudinal reinforcement 302 is arranged in the concrete layer 5 and fixedly connected thereto; one end of the second lap longitudinal reinforcement 402 is arranged in the second prefabricated concrete wall 4 and fixedly connected thereto, and the other end of the second lap longitudinal reinforcement 402 is arranged in the concrete layer 5 and fixedly connected thereto; and the first lap longitudinal reinforcement 302 and the second lap longitudinal reinforcement 402 are arranged one by one and overlap each other. Among them, the concrete layer 5 is a UHPC high-strength concrete layer, and the lap length of the first lap longitudinal reinforcement 302 and the second lap longitudinal reinforcement 402 is ten times the diameter of the first lap longitudinal reinforcement 302 or the second lap longitudinal reinforcement 402, so that the first prefabricated concrete wall 3 and the second prefabricated concrete wall 4 are connected together. Due to the high-strength performance of UHPC concrete, the prefabricated concrete shear wall connection can be made more secure.

[0084] The overlap of UHPC high-strength concrete materials improves the overall structural stiffness and ductility. UHPC high-strength concrete has ultra-high compressive strength, which enables it to withstand greater loads and shear forces, significantly improving the bearing capacity and overall stability of the prefabricated shear wall. It can absorb a large amount of energy during the stress process, showing good ductility and toughness. For the prefabricated shear wall under the action of earthquakes, it can provide better anti-collapse ability and deformation coordination ability, and meet the design requirements of the shear wall device.

[0085] The interior 206 of the embedded mechanical sleeve is a step structure, one end of the first middle longitudinal reinforcement 303 is arranged in the first prefabricated concrete wall 3 and fixedly connected thereto, and the other end of the first middle longitudinal reinforcement 303 is connected to the embedded mechanical sleeve 206; one end of the second middle longitudinal reinforcement 403 is arranged in the second prefabricated concrete wall 4 and fixedly connected thereto, and the other end of the second middle longitudinal reinforcement 403 is connected to the embedded mechanical sleeve 206; the first fixed angle steel 207, the anchor plate 204 and the embedded single-sided sleeve 205 are detachably connected by bolts, the first fixed angle steel 207, the anchor plate 204 and the embedded mechanical sleeve 206 are detachably connected by bolts, the second fixed angle steel 208, the anchor plate 204 and the embedded single-sided sleeve 205 are detachably connected by bolts, and the second fixed angle steel 208, the anchor plate 204 and the embedded mechanical sleeve 206 are detachably connected by bolts.

[0086] Furthermore, the deformable member 202 and the energy dissipation plate 101 in the present invention may be connected to the first assembled concrete wall 3 and the second assembled concrete wall 4 in a different manner than the above-mentioned manner. The first buckling energy dissipation connection assembly 1 and the second buckling energy dissipation connection assembly 2 may be fixed to the first assembled concrete wall 3 and the second assembled concrete wall 4 by means of detachable fixed connection such as threaded connection, clamping connection or pin connection. When it is necessary to replace the first buckling energy dissipation connection assembly 1 or the second buckling energy dissipation connection assembly of a different type, it is only necessary to remove the constraint plate or the connecting angle steel. Only the deformation member 202 and the energy dissipation plate 101 need to be replaced, and there is no need to replace the integral structure formed by the deformation member 202 and the energy dissipation plate 101 or the integral structure formed by the connecting angle steel and the shuttle plate. In other words, the first buckling energy dissipation connection assembly 1 and the second buckling energy dissipation connection assembly 2 in the present invention can meet the shock absorption requirements of different structures by only replacing the deformation member 202 and the energy dissipation plate 101 (that is, the present invention can quickly replace different types of energy dissipation parts). The flexibility of the assembled replaceable energy dissipation parts in the present invention is further improved, the downtime for maintenance is further shortened, and the maintenance cost is further reduced.

[0087] A construction method of an assembled concrete shear wall device based on an energy dissipation connection structure, the specific steps of which include:

[0088] Step S1: preparing a first buckling energy dissipation connection assembly 1, a second buckling energy dissipation connection assembly 2, a first prefabricated concrete wall 3, and a second prefabricated concrete wall 4 in a factory;

[0089] Step S2: transporting the prefabricated components to the construction site, and installing the first prefabricated concrete wall 3 and the second prefabricated concrete wall 4;

[0090] Step S3: disposing the second buckling energy dissipation connection assembly 2 between three points of the first prefabricated concrete wall 3 and the second prefabricated concrete wall 4, and connecting them by bolts;

[0091] Step S4: overlapping the first overlapping longitudinal reinforcement 302 in the first prefabricated concrete wall 3 and the second overlapping longitudinal reinforcement 402 in the second prefabricated concrete wall 4, and molding and pouring UHPC high-strength concrete grouting material into the overlapping part;

[0092] Step S5: The first buckling energy dissipation connection assembly 1 is set at the connection between the first prefabricated concrete wall 3 and the second prefabricated concrete wall 4 at both ends, the end of the first end longitudinal reinforcement 301 passes through the energy dissipation end plate 104 and is fixed by a nut, and the end of the second end longitudinal reinforcement 401 passes through the constraint end plate 105 and is fixed by a nut.

[0093] When the assembled shear wall is subjected to external force in the vertical direction, the first buckling energy dissipation connection assembly 1 on one side is pulled, the first buckling energy dissipation connection assembly 1 on the other end is compressed, and the energy dissipation plates 101 on both sides are displaced in the vertical direction, one energy dissipation plate 101 is compressed and deformed, and the other energy dissipation plate 101 is stretched and deformed, and energy dissipation is achieved through deformation. When an earthquake occurs, its effect on the shear wall is a reciprocating load, that is, the first buckling energy dissipation connection assembly 1 is alternately compressed and stretched, and the energy dissipation plate 101 is repeatedly deformed, thereby achieving reciprocating energy dissipation. In this embodiment, the first buckling energy dissipation connection assembly 1 arranged on both sides in the horizontal direction provides vertical energy dissipation capacity and self-reset capacity, and prevents the bottom concrete on both sides from being damaged under the action of tension; at the same time, the second buckling energy dissipation connection assembly 2 at the bottom at the three-point point can provide sufficient shear bearing capacity for the assembled concrete shear wall, ensuring that the walls on both sides of the bottom of the shear wall will not be damaged by shear after being weakened, avoiding the damage of the bottom concrete at both ends of the shear wall when it is vibrated, and effectively improving the energy dissipation capacity of the assembled shear wall. The device has the characteristics of reasonable force, simple structure, good earthquake resistance, strong self-reset ability, and small post-earthquake damage. However, it should be noted that the modular buckling energy dissipation member and the shuttle plate connector in the present invention are not limited to being installed on buildings.

[0094] In this embodiment, by installing the replaceable second buckling energy dissipation connection assembly 2 at the three-point point of the assembled concrete shear wall and the first buckling energy dissipation connection assembly 1 at the end, the overall shear wall has better shear bearing capacity and energy dissipation capacity under reciprocating load, effectively reducing the damage to the components, and the damaged deformable parts 202 and energy dissipation plates 101 can be replaced after the earthquake. Effectively realizing the restoration of its use function without repair or with a little repair after the earthquake is a current research hotspot and future development trend of earthquake engineering. The structure has the characteristics of reasonable force, simple structure, high bearing capacity, high efficiency energy dissipation, and recoverable function after the earthquake. It realizes effective shock absorption of different structures without dismantling the overall shear wall.

[0095] It should be noted that "replaceable" in the present invention means that under the action of an earthquake, the energy absorbing plate 101 in the first buckling energy absorbing connection assembly 1 and the deformable member 202 in the second buckling energy absorbing connection assembly 2 are deformed under repeated loads, and the purpose of replaceability can be achieved by replacing the deformable member 202 and the energy absorbing plate 101.
