Description

Brickwork pier type energy dissipation device

Technical Field

The utility model relates to the technical field of energy dissipation and shock absorption, in particular to a brickwork buttress type energy dissipation device.

Background

In a general building structure, a filler wall is usually arranged for functional division and external enclosure, wherein masonry walls built by using building blocks and mortar are common filler walls. These masonry walls do not belong to the main structure but provide some additional rigidity to the main structure. Because the tensile strength of the building blocks and the mortar is not high, the bonding strength of the mortar and the interface of the building blocks is also low, and under the action of an earthquake, the masonry wall bears a large earthquake action and is easy to damage and collapse, thereby causing certain influence on the main structure.

In the prior art, in order to improve the safety of the main body structure, energy dissipaters (also called dampers) can be arranged in the main body structure to form an energy dissipation and shock absorption (vibration) structure, so as to reduce the seismic action of the main body structure. The energy dissipater generally adopts the support form or buttress form to be connected with major structure's beam column in the building, and major structure's energy dissipation cushioning effect is mainly realized through the energy dissipater. In particular, the dissipater may generate friction or elastic-plastic hysteresis deformations such as bending, shearing, twisting, etc. to dissipate or absorb energy in the seismic input structure, thereby reducing the seismic response of the host structure. Compared with the support type connection of the energy dissipater, the buttress type connection has the advantages of small influence on building functions, convenience in door and window opening, low manufacturing cost, convenience in construction, capability of directly and effectively ensuring the energy dissipater to play an energy dissipation role in force transmission path and wide application range, and is widely applied.

However, when the existing pier-type energy dissipater is used in a masonry wall, the following problems exist: 1) currently, when energy dissipaters are arranged in a structure, the connection reliability must be considered so that the damper can exert its energy dissipation effect in the earthquake process, therefore, the buttress and the beam column connected with the damper usually need to be particularly reinforced, and meanwhile, in order to ensure the connection reliability of the buttress, the damper and the beam column, the buttress usually adopts reinforced concrete or steel materials. However, on the one hand, the buttress made of reinforced concrete or steel material is difficult to use in brick structure and brick-concrete structure, and is very troublesome to apply. Taking an energy dissipation buttress of a reinforced concrete structure as an example, the traditional reinforced concrete buttress usually adopts cast-in-place construction, the cast-in-place energy dissipation buttress needs to go through the processes of reinforcing steel bar binding, formwork sealing, grouting and the like, a damper must be ensured between two buttresses, the damper and the buttress need to be provided with embedded parts for connection, and the construction process is complex and time-consuming. On the other hand, the use of reinforced concrete or steel materials for the piers inevitably results in additional costs which are acceptable for important buildings but may be less acceptable for general buildings or rural buildings. 2) When adopting reinforced concrete or steel material as buttress in brick structure, brick-concrete structure, buttress and brick wall can't become an organic whole, need additionally to increase the apron in the outside when the wall is decorated.

For the problem that the construction process of a cast-in-place energy dissipation buttress is troublesome, the prior art also provides a buttress for a prefabricated energy dissipation device, for example, a buttress and energy dissipation device connecting node disclosed in the chinese patent zl 202021511391.0, a connecting assembly is pre-embedded on the pier body of the buttress, when assembling the energy dissipation device, a constructor can perform the prefabricated forming of the connecting assembly and the pier body in a workshop, and only the energy dissipation device needs to be connected with the connecting assembly on site, but the buttress does not need to be cast on site, so that the installation steps of the energy dissipation device are reduced, and the installation time of the energy dissipation device is shortened. However, the above solution still has the problems of high additional cost and additional cover plate for wall decoration.

In summary, it is an urgent need to solve the above technical problem to provide a buttress energy dissipater with convenient material availability, simple process, low cost, and especially suitable for brick structure or brick-concrete structure building.

Examples

Referring to fig. 1, a masonry pier type energy dissipater according to an embodiment of the present invention is shown.

The masonry pier energy dissipater 200 comprises a damping portion 210 and piers 220. The damping portion is installed in the body structure 100 through the buttress 220.

The main body structure 100 is preferably a frame structure, and may specifically include an upper beam 110, a lower beam 120, a left side column/shear wall 130, and a right side column/shear wall 140.

The buttress 220 serves as a mounting structure for the damper 210. In particular arrangements, the top and bottom ends of the buttress 220 are rigidly connected to the host structure 100, and there is a gap between the sides of the buttress 220 and the host structure 100. One or more abutments 220 may be provided in the body structure 100 as required. When one buttress 220 is arranged, the buttress 220 is arranged in the middle of the main body structure 100, and gaps are reserved between two sides of the buttress 220 and the left side and the right side of the main body structure 100. When a plurality of buttresses 220 are arranged, the buttresses 220 can be arranged at intervals in the main body structure 100, a first gap is reserved between the buttresses 220 arranged on the left side and the right side and between the left side and the right side of the column/shear wall, a second gap can be reserved between two adjacent buttresses 220, and the widths of the first gap and the second gap can be the same or different. Preferably, the first gap and the second gap have different widths.

The abutment 220 comprises at least an upper abutment 221 and a lower abutment 222 connected by a damping portion 210. The upper buttress 221 and/or the lower buttress 222 are masonry buttress constructed from a plurality of masonry units. Under shock excitation, the upper pier 221 and the lower pier 222 can be relatively displaced by the damping portion 210 to dissipate energy, and simultaneously drive the damping portion to absorb and dissipate seismic energy.

In this embodiment, each of the buttresses of the buttress 222 may be directly formed by building a plurality of masonry units in the vertical direction and the horizontal direction, the building of the masonry units may use building mortar, and the plurality of masonry units of one buttress portion form a rigid whole.

The masonry units are preferably polymer blocks, cement blocks, sintered bricks, gypsum blocks, wood blocks, metal blocks or composite material blocks and the like, and the masonry mortar can adopt high-grade cement mortar. In specific implementation, the masonry unit blocks can be solid blocks, porous blocks or hollow blocks, and the utility model is not limited herein.

The damping portion 210 is capable of damping vibrations, dissipating or absorbing energy in the seismic input structure. The manner in which energy is dissipated or absorbed may be active or passive. For example, energy in the seismic input structure can be dissipated or absorbed by the damping portion 210 producing elastic-plastic hysteresis deformation such as bending, shearing, torsion, etc.; or the energy in the seismic input structure can be dissipated or absorbed by the friction generated by the damping portion 210; energy in the earthquake input structure can be dissipated or absorbed by combining a deformation energy dissipation mode and a friction energy dissipation mode. According to the requirement, the damping part can also adopt other energy consumption modes, such as stirring energy consumption, hydraulic energy consumption and the like.

When the damping part 210 is provided, various dampers, such as a rod-type viscous damper, a viscoelastic damper, a metal friction-type damper, a metal shear-type damper, a lead viscoelastic damper, etc., may be installed between the buttresses of each part of the buttresses 220 as needed; it is also possible to arrange layers of energy dissipating material between the parts of the buttresses 220, said damping being formed by the damping properties of the energy dissipating material. So long as the damping portion 210 allows the pier 220 to undergo relative displacement between floors and is capable of dissipating or absorbing energy in the seismic input structure.

Preferably, the upper buttress and the lower buttress are both masonry buttresses, and the damping part can be a deformation energy dissipation material layer or a friction energy dissipation material layer arranged between the masonry buttresses.

Specifically, the deformation energy dissipation material layer is preferably a viscoelastic damping layer (or viscoelastic layer). When the upper buttress and the lower buttress generate relative displacement, the viscoelastic damping layer is driven to generate shear hysteresis deformation at the same time, so that the energy in the earthquake input structure can be dissipated or absorbed, and the earthquake reaction of the structure is reduced.

By way of example and not limitation, the viscoelastic damping layer may be made of one or more of low-hardness high-damping rubber with viscoelasticity, asphalt, high-performance mortar, and the like.

The friction energy dissipation material layer is preferably a metal friction plate, a nonmetal friction plate or a metal nonmetal composite friction plate. When the upper buttress and the lower buttress generate relative displacement, the friction plates between the masonry buttresses are driven to generate friction, so that the energy in the earthquake input structure can be dissipated or absorbed, and the earthquake reaction of the structure is reduced.

As a typical example and not by way of limitation, the friction plate may employ a steel-steel friction plate, a steel-copper friction plate, a steel-lead friction plate, a copper-lead friction plate, a wood-wood friction plate, or the like.

In a preferred embodiment of this embodiment, the damping part 210 may comprise a damping layer (the abutment 220 is divided into two parts) horizontally arranged between the upper abutment and the lower abutment, and as shown in fig. 1, a flexible connection of the upper abutment 221 and the lower abutment 222 may be formed by the damping layer, so that the upper abutment 221 and the lower abutment 222 can move horizontally relative to each other through the damping part 210.

Specifically, the top end of the upper buttress 221 is rigidly connected to the upper frame rail 110 of the main body structure 100 and the other end thereof is connected to the damping layer, and the bottom end of the lower buttress 222 is rigidly connected to the lower frame rail 120 of the main body structure 100 and the other end thereof is connected to the damping layer. Under vibration excitation, the upper buttress 221 moves with the upper frame beam 110 of the body structure and the lower buttress 222 moves with the lower frame beam 120 of the body structure based on the aforementioned damping layer, enabling horizontal relative displacement between the upper buttress 221 and the lower buttress 222.

Referring to fig. 2, a deformation state of the damper portion 210 is illustrated when the damper portion 210 is a viscoelastic damper layer and horizontal relative displacement occurs between the upper buttress 221 and the lower buttress 222. At this time, the upper surface of the viscoelastic damping layer is fixedly connected with the upper buttress 221, the lower surface of the viscoelastic damping layer is fixedly connected with the lower buttress 222, the main body structure 100 can generate vibration under the excitation of the vibration, the upper frame beam 110 and the lower frame beam 120 of the main body structure 100 can generate reciprocating relative motion, the upper buttress 221 rigidly connected with the upper frame beam is driven to move together when the upper frame beam 110 moves, and the lower buttress 222 rigidly connected with the lower frame beam moves together when the lower frame beam 120 moves, so that the upper buttress 221 and the lower buttress 222 also generate horizontal reciprocating relative motion to consume energy, and meanwhile, the viscoelastic damping layer is forced to generate shear hysteresis deformation to absorb and dissipate the energy of the earthquake.

Referring to fig. 3, a state of the damper portion 210 is illustrated when the damper portion 210 is a friction plate and a horizontal relative displacement occurs between the upper abutment 221 and the lower abutment 222. At this time, the lower portion of the upper buttress 221 may be fixedly mounted with the friction plate 211, and the upper portion of the lower buttress 222 may be fixedly mounted with the friction plate 212. The main body structure 100 can generate vibration under the excitation of the vibration, the upper frame beam 110 and the lower frame beam 120 of the main body structure 100 can generate reciprocating relative motion, the upper frame beam 110 drives the upper buttress 221 rigidly connected with the upper frame beam to move together when moving, and the lower frame beam 120 drives the lower buttress 222 rigidly connected with the lower frame beam to move together when moving, so that the upper buttress 221 and the lower buttress 222 also generate horizontal reciprocating relative motion to consume energy, and meanwhile, friction is forced to generate between the

friction plates

211 and 222, and the energy of the earthquake is absorbed and dissipated.

The way of fixedly mounting the friction plates on the upper buttress 221 and the lower buttress 222 may be bolt connection, pin connection, embedded part connection, adhesive connection, etc., and any connection structure capable of fastening and connecting two objects may be used to mount the friction plates on the buttress, which should not be taken as a limitation to the present invention.

In another embodiment of this embodiment, the number of the damping portions may be multiple, such as two, three, four or more. At this time, a plurality of damping portions are layered in the buttress, and a plurality of horizontal damping layers are formed in the buttress, and referring to fig. 4, a buttress structure in which two horizontal damping layers are formed in the buttress is exemplified.

Adjacent damping layers are connected through a middle buttress 233, through which a flexible connection is formed between the middle buttress 223 and the upper buttress 221, between the middle buttress 223 and the lower buttress 222 and between the middle buttress 223 (when there are more than three damping layers, there are at least 2 middle buttresses, and at this time the middle buttresses are also connected through damping layers). In this embodiment, the middle buttress 223 preferably also adopts a masonry structure, and at this time, the middle buttress is a masonry buttress constructed by a plurality of masonry units.

Specifically, the top end of the upper buttress 221 is rigidly connected to the upper frame beam 110 of the main body structure, and the other end is connected to the uppermost damping layer, and the bottom end of the lower buttress 222 is rigidly connected to the lower frame beam 120 of the main body structure, and the other end is connected to the lowermost damping layer. Under the excitation of vibrations, the upper buttress moves with the upper frame beam of the main structure and the lower buttress moves with the lower frame beam of the main structure, and the middle buttress 223 and the upper buttress 221, the middle buttress 223 and the lower buttress 222 and the middle buttress 222 are horizontally displaceable relative to each other through the aforementioned horizontal damping layer.

Referring to fig. 5, a deformation state of the damper portion 210 is illustrated when the damper portion 210 is a viscoelastic damper layer and horizontal relative displacements occur between the middle buttress 223 and the upper buttress 221 and between the middle buttress 223 and the lower buttress 222. At this time, the upper surface of the first viscoelastic damping layer is fixedly connected with the upper buttress 221, the lower surface of the first viscoelastic damping layer is fixedly connected with the middle buttress 223, the upper surface of the second viscoelastic damping layer is fixedly connected with the middle buttress 223, and the lower surface of the second viscoelastic damping layer is fixedly connected with the lower buttress 222.

The main body structure 100 can generate vibration under the excitation of the vibration, the upper frame beam 110 and the lower frame beam 120 of the main body structure 100 can generate reciprocating relative motion, the upper frame beam 110 drives the upper buttress 221 rigidly connected with the upper frame beam to move together when moving, and the lower frame beam 120 drives the lower buttress 222 rigidly connected with the lower frame beam to move together when moving, so that horizontal reciprocating relative motion is generated between the middle buttress 223 and the upper buttress 221 and between the middle buttress 223 and the lower buttress 222 to consume energy, and meanwhile, the first viscoelastic damping layer and the second viscoelastic damping layer are forced to generate shear hysteresis deformation to absorb and dissipate the energy of the earthquake.

Referring to fig. 6, a state of change of the damping portion 210 is illustrated when the damping portion 210 is a friction plate and horizontal relative displacements occur between the middle abutment 223 and the upper abutment 221 and between the middle abutment 223 and the lower abutment 222. At this time, the lower portion of the upper buttress 221 may be fixedly mounted with the friction plate 211, the upper portion of the lower buttress 222 may be fixedly mounted with the friction plate 212, and the upper and lower surfaces of the middle buttress 223 are respectively mounted with the

friction plates

212 and 211.

The main body structure 100 can generate vibration under the excitation of the vibration, the upper frame beam 110 and the lower frame beam 120 of the main body structure 100 can generate reciprocating relative motion, the upper frame beam 110 drives the upper buttress 221 rigidly connected with the upper frame beam to move together when moving, and the lower frame beam 120 drives the lower buttress 222 rigidly connected with the lower frame beam to move together when moving, so that horizontal reciprocating relative motion is generated between the middle buttress 223 and the upper buttress 221 and between the middle buttress 223 and the lower buttress 222 to consume energy, and meanwhile, friction is generated between the

friction plates

211 and 222 of the upper layer and the lower layer to absorb and dissipate the energy of the earthquake.

Of course, as required, more damping layers can be arranged in the buttress 220, more middle buttresses 223 are correspondingly arranged, and it can be known that more or less damping layers can be arranged as required when the buttress is arranged according to the design size of the building structure, the requirement of the earthquake-resistant level and the construction cost.

The width of the buttress in the span direction can also be adjusted according to actual needs, and the utility model should not be limited.

Further preferably, when the plurality of damping portions are provided on the buttress to form a plurality of damping layers, the plurality of damping layers may adopt different damping modes. For example, when two damping layers are provided, the upper damping layer is a viscoelastic damping layer, and the lower damping layer is a friction plate. Or when three damping layers are arranged, the upper damping layer and the lower damping layer adopt friction plates, and the middle damping layer adopts a viscoelastic damping layer.

According to the technical scheme provided by the utility model, a common masonry for building a wall can be used as a buttress connected with an energy dissipater in an energy dissipation and damping technology, the masonry buttress is connected with a beam in a rigid connection mode, and the masonry buttress and the beam are not subjected to relative displacement after being connected, so that the masonry buttress can be subjected to relative displacement under vibration excitation to realize self energy consumption of the buttress, and meanwhile, the energy dissipater (a damping part in the embodiment) can be driven to operate to absorb or dissipate energy.

The utility model is particularly suitable for being applied to non-reinforced concrete structures such as brick structures, brick concrete structures and the like, and the masonry buttress can be used as a part of a brick wall structure as shown in figure 7, so that a common brick wall has the energy consumption effect, is convenient to obtain materials, does not need complex construction procedures and has low construction cost. On the other hand, because the masonry buttress is rigidly connected with the beam and gaps are reserved on two sides of the structure, the masonry buttress can deform well during vibration and is not easy to damage under large deformation. On the other hand, the masonry buttress and the brick wall are both constructed by masonry, and the wall surface is decorated without additionally adding a cover plate, and only plastering is carried out directly, and the method continues to be shown in fig. 7.

It should be noted that, although the drawings only illustrate that the masonry units are rectangular blocks, those skilled in the art should understand that in actual construction, blocks with other shapes may be used for masonry as required, and the shape of the masonry units should not be taken as a limitation to the scope of the present invention. In addition, the level described in the present embodiment includes a desired level state or a substantially level state. The vertical state in the present embodiment includes an ideal vertical state or a substantially vertical state.

In addition, terms like "comprising," "including," and "having" should be interpreted as inclusive or open-ended, rather than exclusive or closed-ended, by default, unless explicitly defined to the contrary. All technical, scientific, or other terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs unless defined otherwise.
