Description

Technical Field

[0001] The invention relates to the technical field of house construction, in particular to a reinforcement of a wall damper template and a construction method thereof. Background Art

[0002] In recent years, society has attached more and more importance to the earthquake resistance of buildings, and the earthquake resistance structure of buildings has become more and more advanced. Isolation layers, isolation pads, viscous dampers, etc. have emerged in an endless stream, which have greatly improved the earthquake resistance of buildings. However, in the actual construction and installation of viscous dampers, when the post-installation method of viscous energy dissipation components is adopted, it is necessary to check whether the pre-assembly size is larger than the reserved size of the installation position. If the connection structure (cast-in-place concrete component) has poor forming quality, large horizontal deviation, or the misalignment of the anchor bolt and the bolt hole caused by the offset of the embedded plate is greater than the allowable deviation of the regulations or the current national standards, the viscous energy dissipation component will not be in place. Therefore, it is particularly important to control the installation accuracy of the embedded parts and ensure the installation of the viscous damper;

[0003] At present, the installation forms of viscous dampers are divided into: support type, wall type, armpit support type, toggle type and seismic isolation layer pier type. Among them, the wall type connection is widely used in engineering projects due to its advantages of small impact on building functions, flexible layout, convenient construction, and low civil engineering costs. In order to ensure that the damper can play a better role, the wall type viscous damper must ensure that the upper and lower cantilever walls are in the same vertical position during the construction process, and the left and right errors after installation should be controlled within the range of ±20mm, the offset value of the embedded plate should be controlled within ±2mm, and the center line deviation of the bottom plate should be controlled within ±5mm. The existing construction method is mainly to construct the upper and lower cantilever walls separately, and then reinforce the formwork through their own independent support systems. The cantilever wall is usually the same thickness as the masonry wall (generally 200mm). The difficulty lies in that the upper part is a cantilever wall and the lower part is suspended, which makes it difficult to reinforce and support the formwork, and the quality of concrete pouring is difficult to control. In addition, there will be problems such as easy displacement of cantilever wall steel bars, displacement of embedded plates, poor verticality of the wall, expansion of the formwork, and torsion, which makes it impossible to accurately align the upper cantilever wall with the lower cantilever wall, which has a certain impact on the installation accuracy of the subsequent damper. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method for reinforcing a wall damper formwork and a construction method thereof, which solves the problem that the original construction method is affected by site conditions and the workers' level, resulting in upper and lower cantilever wall formwork expansion, large verticality deviation, and embedded parts misalignment, resulting in poor reinforcement effect.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a reinforcement module for a wall damper template, comprising a pressure sensor, a displacement signal receiver, a telescopic support structure, a reinforcement system, an L-shaped molding die, a double-one-shaped base, a one-shaped connecting seat, and an adjustable connecting rod;

[0006] The pressure sensor determines whether the reserved installation height of the viscous damper is exceeded according to the pressure strain gauge of the L-shaped forming mold after the upper and lower cantilever walls are poured with concrete, and transmits the electrical signal to the displacement signal receiver, which then controls the telescopic support structure through the connected circuit board to adjust the position height of the upper and lower embedded steel plates of the cantilever wall;

[0007] The upper cantilever wall and the lower cantilever wall are on the same plane, and the space between the upper and lower cantilever walls is the installation and placement space of the viscous damper, which includes the reinforcement system including the template for installing the cantilever wall, vertical and horizontal support structures;

[0008] An L-shaped forming die is set between the upper and lower cantilever walls to control the molding quality of the cantilever wall side wall positive angle, and at the same time, a double-one-shaped base is embedded and connected, and the cantilever wall is reinforced in the one-shaped connecting seat in the entire length direction, and the L-shaped forming die can slide freely in the double-one-shaped base;

[0009] The adjustable connecting rod is arranged between the upper and lower cantilever walls. When the installation height is insufficient or excessive, the height can be fine-tuned by manually rotating the middle regulating device of the connecting rod. Rotating screws are arranged above and below the embedded steel plates, which can effectively form a supporting effect on the embedded steel plates.

[0010] Preferably, a construction method suitable for reinforcing a wall damper formwork comprises the following steps:

[0011] S1. Installation of lower wall reinforcement binding:

[0012] According to the construction drawings and detailed design, determine the height of the lower wall dowels, and perform the binding construction of the lower wall dowels according to the calculated elevation;

[0013] S2. Installation of lower wall reinforcement:

[0014] After the lower wall reinforcement is tied, clean the surface of the floor slab or frame beam, install the lower steel mesh of the wall according to the detailed drawing, and fix the steel bars;

[0015] S3. Wall formwork installation:

[0016] Fix the wall formwork on the supporting bottom formwork. Pay attention to the control of the bottom formwork elevation during installation. Use reinforcement methods including tension screws, fixed steel pipes and supporting wooden boards.

[0017] S4. Embedded parts installation:

[0018] According to the design detailed drawing, place the embedded parts in the predetermined position of the template and fix the embedded parts with steel bars and concrete;

[0019] S5, upper and lower cantilever wall horizontal plates and side mold closing:

[0020] After the wall formwork is installed, the horizontal plates and side forms of the upper and lower cantilever walls are assembled and fixed by closing the formwork so that the formwork of the upper and lower cantilever walls forms a whole;

[0021] S6, sensor, adjustable support structure installation:

[0022] Install pressure sensors and displacement signal receiving devices to monitor the stress and displacement of the template in real time, and install adjustable support structures;

[0023] S7. Concrete pouring of lower cantilever wall:

[0024] After the formwork and steel structure of the lower cantilever wall are installed and inspected, the concrete pouring operation is carried out. After the pouring is completed, the surface of the concrete is kept flat;

[0025] S8. Measure the installation height between the upper and lower cantilever walls to see if there is any displacement or deformation:

[0026] After the concrete pouring and curing are completed, the installation height between the upper and lower cantilever walls is remeasured using measuring tools to check whether displacement or deformation occurs. If displacement or deformation is found, the adjustable support structure and formwork position are adjusted immediately.

[0027] Preferably, in step S1, the lower wall height is: according to the detailed drawings of the damper installation construction unit,

[0028] The formula for calculating the lower wall height is:

[0029]

[0030] Lower wall reinforcement height: controlled according to the elevation of the detailed drawing. The calculation formula for the lower wall reinforcement height is:

[0031]

[0032] Lower wall reinforcement: The detailed design drawings contain the specific reinforcement of the lower wall, and the construction should be carried out in accordance with the reinforcement requirements of the detailed drawings;

[0033] Hidden beams and columns: According to the design detailed drawing, when there are hidden beams and columns in the lower wall, special attention should be paid to the reinforcement of the hidden beams, which are the same as those of the hidden columns;

[0034] When the steel bars of hidden beams and hidden columns are bent into a gate shape or U shape using the same steel bar, they cannot be disconnected.

[0035] Preferably, in step S2, after the lower wall reinforcement is installed, the reinforcement mesh is tied and fixed.

[0036] Preferably, in the S3 step, when installing the upper cantilever wall formwork, the bottom formwork is installed first, and attention is paid to controlling the elevation of the bottom formwork surface, and the formwork is well supported. The horizontal formwork is used to fix the lower cantilever wall and the upper cantilever wall. The fixed pipe is arranged on the clamping wood square, and the fixed steel pipe is fixed by the tension screw to clamp and fix the clamping wood square. The fixed steel pipe is arranged on both sides of the upper and lower cantilever walls and is clamped and fixed by the tension screw. The tension screw can tighten and fix the fixed steel pipes on both sides. The fixed steel pipe is also used to fix the clamping wood square. The fixed steel pipe connection mode is longitudinal connection, which is used to support the upper cantilever wall.

[0037] Preferably, in the S4 step, after the wall formwork is installed, the embedded parts of the corresponding model are placed near the installation position according to the detailed design drawings, and the edge lines of the embedded parts are marked with red and blue pencils or ink fountains, and the edge lines of the embedded parts are coincident with the vertical and horizontal center lines of the bottom formwork, that is, the plane position of the embedded parts is determined, and nails are hammered into both sides of the embedded parts to fix the positions of the embedded parts to avoid positional displacement of the embedded parts during steel bar binding and concrete pouring. After the position is determined, the left and right errors of the embedded parts after fixed installation should be controlled within 20m. In addition, the offset value of the embedded plate should be controlled within ±2mm, and the deviation of the center line of the bottom plate should be controlled within ±5mm.

[0038] Preferably, in the step S5, the bottom template is installed first when installing the upper cantilever wall template, and attention is paid to the elevation control of the bottom template surface, and the template support embedded parts should be installed before the bottom template and the templates on both sides of the cantilever wall in the width direction are installed. The outer template should be installed in the length direction, and the inner template in the length direction should be reserved. After the damper embedded parts and the steel bars are tied, this template is closed. After the upper and lower cantilever walls are molded together, the finalized mold is assembled. First, a double-one-shaped base is made on the horizontal bottom template of the lower cantilever wall according to the length of the cantilever wall. As well as the assembly of the one-shaped base, the double one-shaped base needs to be set in the direction of the embedded steel plate as much as possible to facilitate the reinforcement and height adjustment of the adjustable connecting rod. The one-shaped base is used to connect the cantilever wall in the length direction, and the connection method is bolt connection. Then an L-shaped forming mold is placed at the outer corner position of the cantilever wall. The L-shaped forming mold can be embedded in the double one-shaped base. By adjusting the embedded position, the distance of the flexible material filled on the left and right sides of the cantilever wall can be adjusted. A round hole is set at a height of 150mm on the side of the L-shaped forming mold.

[0039] Preferably, in the step S6, after the upper and lower cantilever wall horizontal plates and the side molds are closed, the telescopic support structure is placed in the L-shaped forming mold between the upper and lower cantilever walls, and strain gauges are arranged on both sides of the upper part of the L-shaped forming mold. The signals formed by the strain gauges on both sides being stretched or compressed are transmitted to the pressure sensor, which is processed by the displacement signal receiver and then transmitted to the telescopic support structure. The telescopic support structure adjusts the upper and lower support heights, and a manually adjustable support structure is set between the upper and lower cantilever walls. The support structure adjusts the connection height between the double-one-shaped base and the rotating screw in the horizontal direction.

[0040] Preferably, in the step S7, since there is an installation height gap in the middle of the cantilever wall, the lower cantilever wall must be cast first, and the upper cantilever wall can be cast after the concrete solidifies and hardens. The upper cantilever wall must be cast with the same concrete grade as the beam and slab concrete of this layer. Before pouring concrete, the debris in the cantilever wall is cleaned and water is sprinkled into the cantilever wall to ensure that the surface of the floor is fully moistened, but there should not be too much visible water. The lower cantilever wall needs to be chiseled before the mold is completed, and the chiseling depth is controlled within the range of 5-10mm. The finished casting surface must bury all the embedded parts, and the elevation is 5mm higher than the finished surface.

[0041] Preferably, in the step S8, the installation height between the upper and lower cantilever walls is measured to see whether displacement and deformation occur during the pouring of concrete at the lower end. The horizontal mold of the lower cantilever wall is disassembled. After the concrete pouring is completed, the mold needs to be assembled in time, and then the installation height between the upper and lower cantilever walls is measured to see whether it meets the requirements. If it meets the requirements, the concrete pouring of the upper cantilever wall can be continued only after the adjustment of the telescopic support structure and the adjustable connecting rod. During the pouring process, pay attention to the response of the pressure sensor and perform auxiliary height adjustment of the adjustable connecting rod at any time.

[0042] The present invention provides a method for reinforcing a wall damper template and its construction.

[0043] Beneficial effects:

[0044] 1. The present invention fixes the cantilever wall formwork through a reinforcement system (tension screws, fixed steel pipes, clamping wooden boards) in conjunction with a double-one-shaped base, a one-shaped base, and an L-shaped forming mold; effectively ensures the clamping and reinforcement effect of the formwork on the cantilever wall, making the reinforcement effect of the formwork on the cantilever wall better, and the manufactured clamp can be reused, saving costs.

[0045] 2. The present invention can control the molding quality of the positive angle of the side wall of the cantilever wall by setting an L-shaped molding die between the upper and lower cantilever walls. The L-shaped molding die is embedded in the middle of the double-one-shaped base and can slide freely to ensure the distance of the flexible material filled between the cantilever wall and the filling walls on both sides, thereby preventing the occurrence of problems such as insufficient filling length due to mold expansion.

[0046] 3. The present invention arranges pressure sensors, displacement signal receivers, telescopic support structures and other devices in the middle of the upper and lower cantilever walls to cooperate with each other. When the embedded steel plates have problems such as displacement, mold expansion, and twisting during the pouring of concrete, each receiving device can automatically identify and make corresponding height adjustments, so that the device can adapt to the reinforcement work of different cantilever walls and effectively achieve the purpose of controlling the installation accuracy.

[0047] 4. When the installation height is insufficient or excessive, the present invention can manually rotate the middle adjustable connecting rod to fine-tune the height, and provide a high auxiliary effect on the telescopic support structure in the above 3 to ensure the stability of the device and prevent it from overturning due to the pressure during the concrete pouring process. In addition, rotating threads are set up above and below the embedded steel plate, which can not only ensure a certain supporting effect on the embedded steel plate, but also fix the position of the embedded plate, preventing the embedded plate from displacement, wall torsion, verticality deviation, mold expansion and other problems during the concrete pouring and vibration process, thereby ensuring the pouring quality.

[0056] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Please see attached Figure 1 - Attachment Figure 7 , the embodiment of the present invention provides a template reinforcement module suitable for a wall damper, including: a pressure sensor 1, a displacement signal receiver 2, a telescopic support structure 3, a reinforcement system 4, an L-shaped molding die 5, a double-one-shaped base 6, a one-shaped connecting seat 7, and an adjustable connecting rod 8;

[0058] The pressure sensor determines whether the reserved installation height of the viscous damper is exceeded based on the pressure strain gauge of the L-shaped forming mold after the upper and lower cantilever walls are poured with concrete, and transmits the electrical signal to the displacement signal receiver. The displacement signal receiver then controls the telescopic support structure through the connected circuit board, thereby adjusting the position height of the upper and lower embedded steel plates of the cantilever wall.

[0059] The upper cantilever wall and the lower cantilever wall are on the same plane, and the space between the upper and lower cantilever walls is the installation and placement space of the viscous damper, including the template for installing the cantilever wall, vertical and horizontal support structures (4-1 template, 4-2 clamping wooden board, 4-3 tension screws, 4-4 fixed steel pipes) and other reinforcement systems.

[0060] An L-shaped forming mold is set between the upper and lower cantilever walls to control the forming quality of the positive angle of the cantilever wall side wall, and at the same time, a double-one-shaped base is embedded and connected to reinforce the cantilever wall in the entire length direction at the one-shaped connecting seat to ensure the horizontal forming quality of the concrete in the middle part of the cantilever wall. In addition, the L-shaped forming mold slides freely in the double-one-shaped base to ensure the distance of the flexible material filled between the cantilever wall and the filling walls on both sides.

[0061] The adjustable connecting rod is set in the middle of the upper and lower cantilever walls. When the installation height is insufficient or too high, the height can be fine-tuned by manually rotating the middle control device of the connecting rod. Rotating screws are set above and below the embedded steel plates, which can effectively form a certain supporting effect on the embedded steel plates and ensure the fixed position of the embedded plates.

[0062] A construction method suitable for reinforcing a wall damper formwork comprises the following steps:

[0063] S1. Installation of lower wall reinforcement binding

[0064] (1) Lower wall height: According to the detailed drawings of the damper installation construction unit, the calculation formula for the lower wall height is:

[0065]

[0066] Lower wall reinforcement height: controlled according to the elevation of the detailed drawing. The calculation formula for the lower wall reinforcement height is:

[0067]

[0068] (2) Lower wall reinforcement: The detailed design drawings contain the specific reinforcement for the lower wall. During construction, the reinforcement requirements of the detailed design drawings should be followed.

[0069] (3) Hidden beams and columns: According to the detailed design drawing, the lower wall will generally have hidden beams and columns. Pay special attention to the reinforcement of the hidden beams, which are the same as the hidden columns.

[0070] (4) The steel bars for hidden beams and columns are generally made from the same steel bar bent into a gate shape or U shape and cannot be disconnected.

[0071] S2. Installation of upper and lower wall reinforcement

[0072] Before the floor slab (beam) is cast, the lower cantilever wall reinforcement is tied and set according to the construction drawings, and then the upper cantilever wall reinforcement is tied and set on the upper frame beam of the floor.

[0073] S3. Wall formwork installation (reinforcement system)

[0074] The installation of the upper cantilever wall formwork should be preceded by the installation of the bottom formwork, and attention should be paid to the elevation control of the bottom formwork surface, and the formwork should be well supported. The component 4 reinforcement system consists of tension screws, fixed steel pipes, clamped wood and formwork. The horizontal formwork is used to fix the lower cantilever wall and the upper cantilever wall. The fixed pipe is set on the clamped wood, and the fixed steel pipe is fixed by the tension screw, and the clamped wood is clamped and fixed. The fixed steel pipe is set on both sides of the upper and lower cantilever walls, and is clamped and fixed by the tension screw. The tension screw can tighten and fix the fixed steel pipes on both sides, and the fixed steel pipe can also be used to fix the clamped wood. Among them, the fixed steel pipe connection method is longitudinal connection, which is used to support the upper cantilever wall, that is, the fixed steel pipe can not only fix the clamped wood, but also support the upper cantilever wall. In addition, the tension screw is set on the fixed steel pipe, which can also be fixed and pulled, ensuring the integrity of the reinforcement support system.

[0075] S4. Embedded parts installation

[0076] (1) After the wall formwork is installed, the corresponding embedded parts are placed near the installation position according to the detailed design drawings. The edge lines of the embedded parts are marked with red and blue pencils or ink fountains. The edge lines of the embedded parts are aligned with the vertical and horizontal center lines of the bottom formwork. The plane position of the embedded parts is determined. Nails are hammered into the sides of the embedded parts to fix the position of the embedded parts to avoid positional deviation of the embedded parts during steel bar binding and concrete pouring. After the position is determined, the embedded parts are fixed. The left and right errors after installation should be controlled within 20 mm. In addition, the offset value of the embedded plate should be controlled within ±2 mm, and the deviation of the center line of the bottom plate should be controlled within ±5 mm.

[0077] (2) The installation and positioning dimensions of embedded parts should be measured and verified on site. For embedded parts whose installation dimensions exceed the design dimensions but are within the error range, they should be ground flat with a grinder. For those smaller than the design dimensions, equal strength materials should be used for pad welding. Before installing embedded parts, the flatness of the steel plate should be checked. There should not be excessive warping and deformation. After placing them on the bottom template surface, the gap between the embedded parts and the template surface should be checked. There should not be a gap that is too large, and the levelness of the embedded parts should be checked.

[0078] (3) To ensure the construction quality of subsequent installation processes, review the actual elevation and dimensions of the damper installation location according to the damper plan layout, confirm whether the actual construction error affects the installation of the damper-related components, and make adjustments as appropriate. For details on the adjustment method, see Step 8.

[0079] S5, upper and lower cantilever wall horizontal plates and side mold closing

[0080] The bottom template should be installed first when installing the upper cantilever wall template. Pay attention to the elevation control of the bottom template surface and do a good job of supporting the template. Before installing the embedded parts, the bottom template and the templates on both sides of the cantilever wall in the width direction should be installed. The outer template should be installed in the length direction, and the inner template in the length direction should be reserved. After the damper embedded parts and the steel bar binding are completed, this template is closed. After the upper and lower cantilever walls are molded together, the finalized mold is assembled. First, the double-one-shaped base and the one-shaped base are assembled on the horizontal bottom template of the lower cantilever wall according to the length of the cantilever wall. It should be noted here that the double-one-shaped base should be set as much as possible in the direction of the embedded steel plate to facilitate the reinforcement and height adjustment of the adjustable connecting rod. The one-shaped base is used to connect the cantilever wall in the length direction. The connection method can be bolted. Then, an L-shaped finalized mold is placed on the outer corner position of the cantilever wall (double-one-shaped base). The L-shaped finalized mold can be embedded in the double-one-shaped base. By adjusting the embedded position, the distance of the flexible material filled on the left and right sides of the cantilever wall can be adjusted to adapt to different filling thicknesses. The most important thing is that a round hole is set at a height of 150mm on the side of the L-shaped forming mold, which is mainly used to tighten and fix the fixed steel pipes on both sides with tension screws, so that the positive corners of this cantilever wall can be further tightened and strengthened to prevent the continuous impact force on the formwork due to its own gravity during the concrete pouring process, causing the mold to expand at this module position.

[0081] S6, sensor, adjustable support structure installation

[0082] After the horizontal plates and side molds of the upper and lower cantilever walls are closed, the telescopic support structure is placed in the L-shaped final mold between the upper and lower cantilever walls, and strain gauges are arranged on both sides of the upper part of the L-shaped final mold. The signals formed by the strain gauges being stretched or compressed on both sides are transmitted to the pressure sensor, and then transmitted to the telescopic support structure after being processed by the displacement signal receiver. The telescopic support structure adjusts the upper and lower support heights to make high-precision adjustments to the displacement of the upper components. At the same time, in order to ensure the overall stability of the device and avoid the overturning of the horizontal support structure after adjusting the L-shaped final mold, a manually adjustable support structure is set in the middle of the upper and lower cantilever walls. The support structure adjusts the connection height between the double-one-shaped base and the rotating screw in the horizontal direction, which can not only effectively support the embedded steel plate and ensure the fixed position of the embedded plate, but also assist the function of the telescopic support structure, which plays a vital role in maintaining the reinforcement device system.

[0083] S7. Concrete pouring of lower cantilever wall

[0084] (1) Since there is a gap in the middle of the cantilever wall, the lower cantilever wall must be cast first. After the concrete solidifies and hardens, the upper cantilever wall can be cast. The upper cantilever wall must be cast together with the beam and slab concrete of this layer. The concrete grade is the same as the beam. In addition, during the concrete pouring process, it is strictly forbidden to vibrate the embedded parts directly with vibrating rods, equipment or tools.

[0085] (2) Before pouring concrete, it is necessary to clean up the debris inside the cantilever wall in time and sprinkle water into the cantilever wall to ensure that the surface of the floor is fully moistened, but there should not be too much visible water. The lower cantilever wall needs to be chiseled before the mold is closed. The chiseling depth should be controlled within the range of 5-10mm to ensure good adhesion between the newly poured concrete and the cantilever wall.

[0086] (3) The finished surface must be cast to cover all embedded parts, and the elevation can be 5mm higher than the finished surface.

[0087] S8. Measure the installation height between the upper and lower cantilever walls to see if there is any displacement or deformation.

[0088] During the pouring of concrete at the lower end, the horizontal mold of the lower cantilever wall can be split to ensure the quality of the concrete in the horizontal direction. After the concrete pouring is completed, the mold needs to be assembled in time, and then the installation height between the upper and lower cantilever walls is measured to see if it meets the requirements. If the requirements are met, the concrete pouring of the upper cantilever wall can be continued after the telescopic support structure and the adjustable connecting rod are adjusted. During the pouring process, pay attention to the reaction of the pressure sensor and adjust the height of the adjustable connecting rod at any time to avoid problems such as mold expansion, wall torsion and verticality difference. If the requirements are not met, adjust the telescopic support structure or the adjustable connecting rod to meet the requirements.

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
