Description

Technical Field

[0001] This invention relates to the technical field of construction vibration damping equipment installation, specifically to an installation structure and method for a coupling beam damper. Background Technology

[0002] Coupling beam dampers, also known as coupling beam energy dissipators, are energy dissipation and vibration reduction elements. Coupling beam energy dissipators are typical displacement-type energy dissipators, providing both additional damping and stiffness to the structure. During earthquakes, they act as a structural safety net, protecting shear wall structures from damage or reducing the degree of damage. They are particularly suitable for residential building structures. Their long-term functionality and maintenance costs are highly advantageous, making them one of the most widely used energy dissipators in practical engineering. The maximum output of coupling beam dampers used in conventional building structures is typically 7.5~80 tons, and the thickness is generally no more than 200mm. When placed in building partition walls, they can meet the thickness requirements of most buildings.

[0003] Due to the significant weight of the coupling beam damper, the following problems may arise during construction and installation: 1. The coupling beam damper is prone to lateral displacement, resulting in inconsistent protective layer thickness on both sides of the damper. How to quickly install the protective layer of the coupling beam damper? 2. How to enhance the bonding ability between the surface of the coupling beam damper and the concrete structure? 3. How to enhance the bond strength between the anchor bars of the coupling beam damper and the concrete? 4. The cast coupling beam concrete is prone to voids. How to improve the forming quality of the coupling beam damper area after demolding? 5. The fabrication of beam reinforcement at short beam sections is troublesome and requires a large investment of labor costs.

[0004] Patent application CN201910738865.5 discloses a friction-type coupling beam damper and its usage method, including a connector comprising a left connector and a right connector, which are respectively installed in the middle of the coupling beam between the left and right coupling shear walls and connect the opposite ends of the coupling beam; a constraint part disposed between the left connector and the right connector for connecting the left connector and the right connector, the constraint part being a flat plate structure, one side of the constraint part being welded and fixed to the left connector, and the other side being fixedly connected to the left connector by fixing bolts; and a middle shear plate disposed on the right connector and attached to the inner side of the constraint part, the middle shear plate being connected to the constraint part by a butterfly spring and connecting bolts. The beneficial effects are: better protection for the coupling beam itself, the shear wall members on both sides, and the bottom shear wall members; constant frictional force, which limits the upper limit of internal forces in the surrounding structural members connected to it, thereby reducing the design and construction difficulty of the surrounding connecting members; and the ability to achieve rapid repair and restoration after an earthquake. However, this scheme does not provide effective technical solutions to problems such as lateral displacement of the damper installation and the tendency for voids to form in the concrete after molding. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems by providing an installation structure and method for a coupling beam damper, including the mechanical connection of the anchoring steel bars of the coupling beam damper; hoisting the coupling beam damper into place; binding the coupling beam steel bars and the anchoring steel bars of the coupling beam damper; closing the coupling beam formwork and pouring concrete; this invention effectively reduces construction costs and shortens construction time by optimizing the installation structure and method.

[0006] The technical solution adopted in this invention is as follows:

[0007] This invention discloses an installation structure for a coupling beam damper, including a coupling beam template and a floor slab template. The coupling beam damper is placed inside the coupling beam template, and an outer enclosure is provided on the coupling beam damper. The outer enclosure wraps around the coupling beam damper, forming an integrated structure of the damper outer enclosure. The thickness of the outer enclosure is the same as the thickness of the protective layer of the coupling beam damper. The integrated structure of the damper outer enclosure is placed in the middle area of ​​the coupling beam template to form a preliminary positioning and installation structure for the coupling beam damper.

[0008] Furthermore, it includes a connecting sleeve, which is disposed on the connecting beam damper and has anchor bars. Concrete is poured inside the connecting beam formwork to form the connecting beam structure, and the anchor bars are used to anchor the connecting beam to the concrete.

[0009] Furthermore, the connecting beam is provided with upper longitudinal reinforcement and lower longitudinal reinforcement, which are separated in the middle area of ​​the connecting beam, forming a space for placing the connecting beam damper; stirrups are equidistantly arranged along the length of the upper and lower longitudinal reinforcements of the connecting beam, and the stirrups restrict the positional relationship between the upper and lower longitudinal reinforcements and the anchor bars, forming a secondary positioning and installation structure for the connecting beam damper within the connecting beam.

[0010] Furthermore, the floor slab formwork is set on the connecting beam formwork, and the floor slab structure is formed after the concrete is poured into the floor slab formwork; the height of the connecting beam damper is set higher than the height of the connecting beam, and the upper part of the connecting beam damper is set within the floor slab area. After concrete is poured, the connecting beam damper, the connecting beam, and the floor slab form an integral structure.

[0011] Furthermore, the floor slab formwork is provided with floor slab support reinforcement and additional reinforcement. The floor slab support reinforcement is placed on the additional reinforcement and arranged perpendicular to each other to form a support skeleton within the floor slab.

[0012] Furthermore, one end of the anchor bar of the connecting beam damper is connected to the connecting beam damper through a connecting sleeve, and the other end is anchored to the concrete in the connecting beam. The end of the anchor bar of the connecting beam damper connected to the concrete is provided with a connecting bolt, which is fixed by the thread engagement on the anchor bar.

[0013] Furthermore, the anchor bars include several groups, which are equidistantly arranged along the height direction of the connecting beam damper. Each group of anchor bars includes two anchor bars arranged in parallel and anchored to the concrete of the connecting beam.

[0014] This invention discloses a method for installing a coupling beam damper, comprising the following steps:

[0015] S1: Determine the installation point of the connecting beam damper, transport the connecting beam damper and components required for the installation point to the vicinity of the installation point, measure the relevant dimensions of the installation point and compare them with the dimensions of the connecting beam damper and components, record the error between the measured dimensions of the installation point and the product and components, formulate a correction plan for the dimensional error, and use measuring tools to mark and position the installation point.

[0016] S2: Connection of coupling beam reinforcement and shear wall reinforcement, including the binding steps of shear wall and coupling beam reinforcement. The shear wall and coupling beam reinforcement are laid out and cut in sequence: binding the shear wall reinforcement and binding the coupling beam reinforcement at the junction of the shear wall and coupling beam. After the reinforcement workers fix the coupling beam reinforcement, they put the stirrups on the coupling beam reinforcement according to the calculated number of stirrups. After the damper is installed, it is fixed and bound. After the reinforcement is bound, the formwork on both sides of the shear wall is erected.

[0017] S3: Measure and lay out the lines, mark the edge lines of the formwork support; erect and reinforce the bottom formwork at the connecting beam location; erect the connecting beam formwork at the location of the connecting beam damper. The connecting beam formwork is of fixed size and is marked with special formwork. On the floor where the damper is installed, the connecting beam formwork at the corresponding position of the floor is installed. No reprocessing is required. After the floor, bottom beam formwork and one side formwork of the shear wall are completed, the damper can be installed.

[0018] S4: Hoist the damper to the bottom formwork position of the connecting beam, tie the anchor bars of the connecting beam damper and the longitudinal bars of the connecting beam. The longitudinal bars of the connecting beam include the upper longitudinal bars and the lower longitudinal bars of the connecting beam. Before hoisting, tighten the anchor bars of the connecting beam damper to the connecting sleeves at both ends of the connecting beam damper. The tower crane hoists the connecting beam damper to the corresponding connecting beam position, adjust the connecting beam damper to the installation line, adjust the installation accuracy centerline deviation to be less than 5mm, and level the bidirectional error to be less than 0.5%.

[0019] S5: After the coupling beam damper is installed in place, tie the damper to the longitudinal reinforcement of the coupling beam, mark the position of the stirrups on the longitudinal reinforcement of the coupling beam, and tie the stirrups in sequence. After the coupling beam stirrups are tied, the coupling beam damper and the longitudinal reinforcement of the coupling beam are longitudinally and horizontally corrected. The bottom edge of both sides of the coupling beam damper and the bottom template edge of the coupling beam are left with an equal distance, and the distance error is less than 5mm. The width of the coupling beam damper is more than 2cm narrower than the cross section of the coupling beam.

[0020] S6: When pouring concrete, during the concrete pouring and vibration process, when the damper of the connecting beam is placed, the concrete vibration intensity is increased at 50cm on both sides of the damper so that the concrete mortar can fill the gap between the formwork of the connecting beam and the damper of the connecting beam.

[0021] Furthermore, in step S6, self-compacting concrete is used for pouring.

[0022] Furthermore, this includes installing an attached vibrator on the outside of the connecting beam, and first pouring ordinary concrete for the walls and columns to 10cm from the bottom of the beam when pouring concrete on the floor, then starting to pour self-compacting concrete, with the self-compacting concrete being poured in conjunction with the attached vibrator.

[0023] The technical effects of this invention are as follows:

[0024] This invention provides an installation structure and method for a coupling beam damper, which effectively solves the problems of difficult installation, substandard quality, and inability to guarantee installation accuracy of coupling beam dampers on construction sites.

[0025] Specifically as follows:

[0026] 1. This invention solves the problem of insufficient protective layers on both sides of the connecting beam damper. By setting an integrated structure of the outer enclosure of the connecting beam damper, it achieves the goals of saving costs, improving work efficiency, and saving materials in the installation of the connecting beam damper, and effectively improves the molding quality and aesthetics of concrete.

[0027] 2. This invention enhances the adhesion between the surface of the connecting beam damper and the concrete structure. The use of wire mesh to wrap the connecting beam damper increases the frictional density of the damper surface. At the same time, the mesh structure of the wire mesh itself can also increase the adhesion between the damper and the concrete.

[0028] 3. This invention enhances the bond strength between concrete and the anchor bars of the coupling beam damper. By using additional anchor bolts, the anchor bars of the damper have more allowance, which improves the bond strength with concrete, resulting in a more significant application effect and a significant increase in the building's safety factor.

[0029] 4. This invention improves the concrete forming quality of the coupling beam damper section. By using self-compacting concrete in conjunction with an inserted attached vibrator, cement slurry can be effectively allowed to enter the protective layer of the coupling beam damper, thus improving the concrete forming quality and preventing voids from forming in the concrete.

Detailed Implementation

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] The data used in this embodiment is a preferred solution, but it is not intended to limit the present invention.

[0037] This embodiment is applied to high-rise buildings with a seismic intensity of 9 degrees and a site category of Class III, where the seismic force is enormous.

[0038] Example 1

[0039] like Figure 1-3 As shown, this embodiment provides an installation structure for a coupling beam damper, including a coupling beam template and a floor slab template. The coupling beam damper is placed inside the coupling beam template, and an outer enclosure is provided on the coupling beam damper. The outer enclosure wraps around the coupling beam damper, forming an integrated structure of the damper outer enclosure. The thickness of the outer enclosure is the same as the thickness of the protective layer of the coupling beam damper. The integrated structure of the damper outer enclosure is placed in the middle area of ​​the coupling beam template to form the initial positioning and installation structure of the coupling beam damper.

[0040] To ensure convenience and aesthetics during later decoration, and to leave room for the protective layer while fixing the damper, the existing technology involves manually installing pads at the bottom and sides of the damper. This process is difficult to install the pads and can easily cause the damper to shift during the construction of the connecting beam reinforcement. After the shift, one side may have insufficient protective layer.

[0041] In this embodiment, to address the issue of the protective layer thickness between the connecting beam dampers, preferably, a 25mm thick outer casing is provided around the connecting beam damper to form an integrated structure. This integrated structure not only facilitates transportation but also significantly shortens the installation time of the connecting beam dampers, reducing the construction period and saving labor.

[0042] Setting the protective layer of the connecting beam damper to 25mm is problematic because using a pad as the protective layer can easily lead to displacement and make installation difficult, and the forming quality is poor after demolding. Preferably, two stainless steel bolts are installed on the surface of the connecting beam damper, and the thickness of the protective layer is controlled by rotating the bolts. The size of the protruding part is determined according to the outer dimensions of the connecting beam damper. During construction, the position is marked on the bottom formwork of the beam, and the connecting beam damper is installed in the corresponding position on the beam.

[0043] In this embodiment, a connecting sleeve is included, which is disposed on the connecting beam damper. Anchor bars are provided on the connecting sleeve. Concrete is poured into the connecting beam formwork to form the connecting beam structure. The anchor bars are anchored to the concrete of the connecting beam. One end of the anchor bar of the connecting beam damper is connected to the connecting beam damper through the connecting sleeve, and the other end is anchored to the concrete in the connecting beam. A connecting bolt is provided at the end of the anchor bar of the connecting beam damper connected to the concrete. The connecting bolt is fixed by the thread engagement on the anchor bar.

[0044] In this embodiment, to ensure sufficient bond strength between the anchor bars of the coupling beam damper and the concrete anchor, bolts are installed at the ends of the reinforcing bars. These bolts are tightened with a torque wrench using threaded steel bars, and the bolts are secured through the threaded connection on the anchor bars. Preferably, in this embodiment, six-nut bolts are used, with the bolt type and specifications matching the anchor bars. One six-nut bolt is installed on each anchor bar to enhance the bond strength with the concrete. By analyzing the original bond strength between the threaded steel bars and the concrete, and considering the on-site construction conditions, installing one six-nut bolt at the end of each anchor bar enhances the bond strength between the coupling beam damper and the concrete, preventing the damper from falling off due to insufficient bond strength after an earthquake.

[0045] In this embodiment, anchor bars are connected to both ends of the connecting beam damper. A layer of wire mesh is installed on the connecting beam damper, surrounding the surface of the damper's housing and matching the external dimensions of the damper. The horizontal and vertical spacing of the wire mesh is 0.5-2 cm. The wire mesh is attached to the surface of the connecting beam damper with rivets. The connecting beam is an ideal location for energy-dissipating elements. Placing the damper at the connecting beam, and using the energy-dissipating material within the damper to form a "shock absorber-fuse" energy dissipation and vibration reduction mechanism, can effectively improve the seismic resistance of high-rise shear wall structures.

[0046] In this embodiment, the connecting beam is provided with upper longitudinal reinforcement and lower longitudinal reinforcement. The upper and lower longitudinal reinforcements are separated in the middle area of ​​the connecting beam, and the separated space forms a space for placing the connecting beam damper. Stirrups are equidistantly arranged along the length direction of the upper and lower longitudinal reinforcements of the connecting beam. The stirrups restrict and position the relationship between the upper and lower longitudinal reinforcements and the anchor bars, forming a secondary positioning and installation structure for the connecting beam damper within the connecting beam.

[0047] In this embodiment, the floor slab formwork is set on the connecting beam formwork, and the floor slab structure is formed after the concrete is poured into the floor slab formwork; the height of the connecting beam damper is set higher than the height of the connecting beam, and the upper part of the connecting beam damper is set within the floor slab area. After the concrete is poured, the connecting beam damper, the connecting beam, and the floor slab form an integral structure.

[0048] In this embodiment, the floor slab template is provided with floor slab support reinforcement and additional reinforcement. The floor slab support reinforcement is placed on the additional reinforcement and arranged perpendicular to the additional reinforcement to form a support skeleton in the floor slab.

[0049] In this embodiment, the anchor bars include several groups, which are equidistantly arranged along the height direction of the connecting beam damper. Each group of anchor bars includes two anchor bars arranged in parallel and anchored to the concrete of the connecting beam. According to the installation and application of the connecting beam damper in connecting beams of different sizes, the arrangement spacing of the upper and lower anchor bars is selected based on the average value of the beam height and beam width. An additional parallel anchor bar of the same length is added on the anchor bars at the same horizontal height, which increases the lap area between the anchor bars of the connecting beam damper and the steel bars in the connecting beam, and increases the contact area with the concrete structure, so that the structural integrity of the connecting beam damper installed in the connecting beam is better.

[0050] Example 2

[0051] like Figure 1-3 As shown, this embodiment provides a method for installing a coupling beam damper, including the mechanical connection of the coupling beam damper anchoring steel bars; hoisting the coupling beam damper into place; binding the coupling beam steel bars and the coupling beam damper anchoring steel bars; and closing the coupling beam formwork and pouring concrete. Specifically, it includes the following steps:

[0052] S1: Determine the installation point of the connecting beam damper, transport the connecting beam damper and components required for the installation point to the vicinity of the installation point, measure the relevant dimensions of the installation point and compare them with the dimensions of the connecting beam damper and components, record the error between the measured dimensions of the installation point and the product and components, formulate a correction plan for the dimensional error, and use measuring tools to mark and position the installation point. The length of the cross section in the middle area of ​​the connecting beam where the connecting beam damper is installed is matched with the connecting beam damper.

[0053] S2: Connection of coupling beam reinforcement and shear wall reinforcement, including the binding steps of shear wall and coupling beam reinforcement. The shear wall and coupling beam reinforcement are laid out and cut in sequence: binding the shear wall reinforcement and binding the coupling beam reinforcement at the junction of the shear wall and coupling beam. After the reinforcement workers fix the coupling beam reinforcement, they put the stirrups on the coupling beam reinforcement according to the calculated number of stirrups. After the damper is installed, it is fixed and bound. After the reinforcement is bound, the formwork on both sides of the shear wall is erected.

[0054] S3: Measure and lay out the lines, mark the edge lines of the formwork support; erect and reinforce the bottom formwork at the connecting beam location; erect the connecting beam formwork at the location of the connecting beam damper. The connecting beam formwork is of fixed size and is marked with special formwork. On the floor where the damper is installed, the connecting beam formwork at the corresponding position of the floor is installed. No reprocessing is required. After the floor, bottom beam formwork and one side formwork of the shear wall are completed, the damper can be installed.

[0055] S4: Hoist the damper to the bottom formwork position of the connecting beam, tie the anchor bars of the connecting beam damper and the longitudinal bars of the connecting beam. The longitudinal bars of the connecting beam include the upper longitudinal bars and the lower longitudinal bars of the connecting beam. Before hoisting, tighten the anchor bars of the connecting beam damper to the connecting sleeves at both ends of the connecting beam damper. The tower crane hoists the connecting beam damper to the corresponding connecting beam position, adjust the connecting beam damper to the installation line, adjust the installation accuracy centerline deviation to be less than 5mm, and level the bidirectional error to be less than 0.5%.

[0056] S5: After the coupling beam damper is installed in place, tie the damper to the longitudinal reinforcement of the coupling beam, mark the position of the stirrups on the longitudinal reinforcement of the coupling beam, and tie the stirrups in sequence. After the coupling beam stirrups are tied, the coupling beam damper and the longitudinal reinforcement of the coupling beam are longitudinally and horizontally corrected. The bottom edge of both sides of the coupling beam damper and the bottom template edge of the coupling beam are left with an equal distance, and the distance error is less than 5mm. The width of the coupling beam damper is more than 2cm narrower than the cross section of the coupling beam.

[0057] S6: When pouring concrete, during the concrete pouring and vibration process, when the damper of the connecting beam is placed, the concrete vibration intensity is increased at 50cm on both sides of the damper so that the concrete mortar can fill the gap between the formwork of the connecting beam and the damper of the connecting beam.

[0058] In this embodiment, different sizes of coupling beam dampers are used to adapt to the location of coupling beams of different sizes. The fabrication of beam reinforcement is complicated at short beam locations and requires more manual intervention. Preferably, the length of the coupling beam is 800mm, the energy dissipator part of the coupling beam damper is 300mm long, the anchor bar is 510mm long, and the total length of the coupling beam damper is 1320mm. The total length of the damper is greater than the length of the coupling beam. The anchor bar of the coupling beam damper extends into the shear wall. When fabricating the coupling beam reinforcement, the installation of the coupling beam damper involves first fitting the coupling beam stirrups onto the anchor bars, then attaching the anchor bars, and finally fabricating the beam reinforcement.

[0059] In this embodiment, due to the large diameter and quantity of the anchor bars at both ends of the metal damper, the numerous and large-diameter longitudinal bars of the connecting beam itself, and the large diameter and small spacing of the stirrups, the reinforcement at the metal damper is very dense. This leads to localized incomplete compaction when using a common immersion vibrator to vibrate the concrete at the connecting beam during concrete pouring. In the early stages of the connecting beam damper construction, after the concrete pouring and formwork removal, concrete quality problems such as hollow areas and cracks were found at the connecting beam damper.

[0060] Because ordinary concrete requires the insertion of a vibrator to compact it in order to achieve the required quality, this embodiment uses self-compacting concrete for pouring. Self-compacting concrete has the characteristics of high fluidity, non-segregation, uniformity and stability. During pouring, it relies on its own weight to flow and achieves compaction without the need for vibration.

[0061] In this embodiment, an attached vibrator is installed on the outside of the connecting beam. When pouring concrete on the floor, ordinary concrete for the wall columns is first poured to 10cm from the bottom of the beam, and then self-compacting concrete is poured. The self-compacting concrete is poured in conjunction with the attached vibrator to ensure the quality of the concrete pouring. Furthermore, a fine aggregate concrete is used, and the quality of the protective layer concrete is ensured by fully vibrating the fine aggregate around the damper.

[0062] Example 3

[0063] In this embodiment, the design calculation of the embedded parts of the connecting beam damper installation structure is performed;

[0064] Preferably, the smallest cross-section connecting beam is selected for verification; rectangular beam cross-section: b=250mm, h=500mm;

[0065] Rectangular beam length: L=1100mm; damper length: L1=300mm; support length: L2=400mm;

[0066] Design value of ultimate damping force of damper: F=200KN;

[0067] Anchor bar setting conditions: Number of straight anchor bar layers: 3 layers; Layer spacing b1: 160mm; Number of straight anchor bar rows: 2 rows;

[0068] Column spacing b2: 80mm; Anchor plate thickness t: 20mm; Anchor plate width B: 200mm; Anchor plate height H: 380mm;

[0069] The distance between the outermost anchor bars is z: 280mm;

[0070] Structural importance coefficient: γ0: 1.0; Influence coefficient of anchor bar number layers α T 0.9;

[0071] Seismic adjustment coefficient for bearing capacity: γ RE :1.0; Anchor grade: HRB500, f y >300N / mm 2 Take f y =300N / mm 2

[0072] Straight anchor bar diameter d: 25mm;

[0073] The bearing capacity of the anchor bars was verified based on the above design data;

[0074] (1) Shear capacity coefficient αv of anchor bars:

[0075]

[0076] (2) Bending deformation reduction factor αb of anchor bars:

[0077]

[0078] (3) Verification of the area of ​​straight anchor bars:

[0079] Under the action of damper shear force, the calculated cross-sectional area of ​​the straight anchor bar is calculated according to the standard: Under the combined action of damper shear force and bending moment, the required anchor bar area for the door lock should meet the following requirements:

[0080]

[0081] When αv is greater than 0.7, we take αv = 0.7.

[0082]

[0083] From the above calculation formula, we can obtain that

[0084]

[0085] In this embodiment, six 25mm anchor bars are used, with an actual area of ​​2943mm². 2 It is greater than 1.25 times the calculated value. The requirement is met.

[0086] Calculation of anchorage length of anchor bar

[0087] The embedded reinforcing bars are mechanically anchored using bolt anchors at the ends. According to relevant design specifications, the length calculation formula is as follows:

[0088] ;

[0089] When the thickness of the protective layer of the anchoring steel bar in the direction of force is 3d, the correction factor can be taken as 0.80.

[0090] When mechanical anchoring is used, the anchoring length (projected length), including the anchoring end, can be taken as 60% of the basic anchoring length.

[0091] Therefore, the length of the anchoring reinforcement is

[0092]

[0093] Based on the calculation of tension anchor bars, the length of the pre-embedded steel bar is 510mm, which meets the requirements.

[0094] In this embodiment, a shear-type coupling beam damper is used, and the anchor bar is a shear-loaded straight anchor bar. The anchorage length of the shear-loaded straight anchor bar should not be less than 15d=375mm. Considering the embedded parts for seismic action, the anchorage length of the reinforcing bar meets the design requirements and is increased by 10%.

[0095]

[0096] Therefore, in this embodiment, considering safety margin, the anchor bar length is 510mm, and a bolt anchor head is added at the end.

[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
