Description

Technical Field

[0001] This invention relates to the field of building structure reinforcement technology, and in particular to a precast concrete column reinforcement and anti-misalignment structure and its installation method. Background Technology

[0002] With the rapid development of the construction industry, the application of precast concrete columns in building structures is becoming increasingly widespread. Building reinforcement is a branch of civil engineering construction. According to statistics, a large number of old houses built in my country in the 1950s and 1960s need reinforcement because they have exceeded their design reference period. Approximately one-third of the country's residential buildings lack sufficient safety reserves, and urban residential structures are gradually aging, requiring reinforcement and maintenance. At the same time, with national restrictions on structural construction investment, and considering cost savings, there is an increasing number of older structures and buildings being utilized, leading to a gradual increase in projects requiring reinforcement.

[0003] Precast concrete components are widely used in construction projects. Due to their heavy weight, they are prone to misalignment during transportation and installation, affecting structural quality. Traditional precast concrete components are connected only by concrete joints, which are susceptible to cracking or even breakage under heavy loads, and cannot effectively resist misalignment caused by external forces.

[0004] Furthermore, in earthquake-prone areas, concrete components are prone to displacement under seismic loads, affecting structural safety; wind and rain erosion can also lead to aging of concrete joints, reducing the overall performance of the structure. Meanwhile, traditional precast concrete column reinforcement and anti-displacement structures typically employ welding and bolting methods, which are not only complex to operate but also require specialized personnel and are costly.

[0005] Therefore, there is an urgent need for a new type of precast concrete column reinforcement and anti-misalignment structure and its installation method to solve the problems in the existing technology. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a precast concrete column reinforcement and anti-misalignment structure and its installation method.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a precast concrete column reinforcement and anti-misalignment structure, comprising: a plurality of precast columns, a reinforcement member connected to the plurality of precast columns, and a connector disposed between the precast columns and the reinforcement member;

[0008] The precast column includes: a plurality of vertical precast columns and a plurality of horizontal precast columns, a plurality of longitudinal ribs disposed in the vertical precast columns, a plurality of transverse ribs disposed in the horizontal precast columns, and vertical and horizontal traction pipes disposed inside the vertical and horizontal precast columns along their length direction; steel ropes are disposed inside the vertical and horizontal traction pipes.

[0009] The connector includes a vertical connector and a horizontal connector; the vertical connector includes a vertical connecting plate connected to the longitudinal reinforcement extending from the surface of the vertical precast column, and a first extension channel disposed within the vertical connecting plate; the horizontal connector includes a horizontal connecting plate connected to the transverse reinforcement extending from the surface of the horizontal precast column, and a second extension channel disposed within the horizontal connecting plate.

[0010] The reinforcement component includes: a reinforcement body detachably connected to the vertical connector and the horizontal connector, and a plurality of reinforcement channels formed inside the reinforcement body.

[0011] In a preferred embodiment of the present invention, a reinforcing member is provided at the connection between the vertical connecting member and the horizontal connecting member. The reinforcing member includes: a first reinforcing plate disposed on the vertical connecting member and a second reinforcing plate disposed on the horizontal connecting member; the first reinforcing plate and the second reinforcing plate are an integral structure.

[0012] In a preferred embodiment of the present invention, both the first reinforcing plate and the second reinforcing plate include: a main board, a plurality of parallel arms extending in the same direction on one side of the main board, and a plurality of connecting holes formed on the parallel arms; the connecting holes on the parallel arms are arranged in a horizontal array along the main line of the parallel arms.

[0013] In a preferred embodiment of the present invention, both the vertical precast column and the horizontal precast column are provided with a plurality of tie bars inside. Both the vertical tie pipe and the horizontal tie pipe are fixedly connected to one side of the plurality of tie bars, and the other side of the tie bars is fixedly connected to the precast column.

[0014] In a preferred embodiment of the present invention, the outer diameter of the steel rope is equal to the inner diameter of the vertical traction pipe and the horizontal traction pipe.

[0015] In a preferred embodiment of the present invention, the vertical pulling pipe and the horizontal pulling pipe are one of a steel wire mesh reinforced polyethylene composite pipe, a stainless steel pipe, or a steel-plastic composite pipe.

[0016] In a preferred embodiment of the present invention, the vertical connecting plate extends with a steel hoop plate in the direction of the vertical precast column group, and the horizontal connecting plate also extends with the steel hoop plate in the direction of the horizontal precast column group.

[0017] In a preferred embodiment of the present invention, both the vertical connecting plate and the horizontal connecting plate are provided with bolt connection holes for the longitudinal ribs and the transverse ribs to pass through, and are fastened together by nuts.

[0018] This invention also provides an installation method for a precast concrete column reinforcement and anti-dislocation structure, comprising the following steps:

[0019] S1. Prefabricated columns: Prepare vertical and horizontal prefabricated columns, place them in the predetermined positions, and ensure their verticality and horizontality.

[0020] S2. Install the connectors: First, install the vertical connectors onto the vertical precast column, ensuring they are connected to the longitudinal reinforcement, and align the first extension channel with the vertical tie pipe; then install the horizontal connectors onto the horizontal precast column, ensuring they are connected to the transverse reinforcement, and align the second extension channel with the horizontal tie pipe; finally, use nuts to thread the connectors to the precast column through the bolt holes.

[0021] S3. Connecting reinforcement components: Connect the reinforcement body to the vertical and horizontal connectors, and ensure that the reinforcement channel is aligned with the vertical and horizontal tension pipes inside the precast column;

[0022] S4. Install the reinforcing plates: Place the first and second reinforcing plates on the surfaces of the vertical and horizontal connectors respectively, pass the steel rope through the precast column, the reinforcing member and the connector, and tighten the steel rope to complete the installation.

[0023] In a preferred embodiment of the present invention, in step S4, a plurality of connection holes on the parallel arm are assembled by a dry connector for respectively setting the first reinforcing plate and the second reinforcing plate on the surfaces of the vertical connector and the horizontal connector.

[0024] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0025] (1) This invention provides a reinforced and anti-misalignment structure for precast concrete columns and its installation method. Through multiple connections between the reinforcement components, connectors and precast columns, the stability and load-bearing capacity of the precast concrete columns can be significantly improved, and damage caused by external factors such as earthquakes and wind loads can be reduced. The reinforcement components and connectors in this structure can be reused, reducing material waste. At the same time, materials such as steel ropes and steel wire mesh reinforced polyethylene composite pipes also have a long service life and are environmentally friendly.

[0026] (2) The present invention adopts vertical and horizontal precast columns, as well as built-in longitudinal and transverse reinforcement, making the structure more robust and effectively preventing the precast columns from shifting and overturning under geological disasters such as earthquakes; at the same time, through the built-in vertical and horizontal traction pipes, as well as the steel ropes in the pipes, the three-dimensional connection of the precast columns can be realized, effectively improving the seismic resistance of the overall structure, and the tension of the steel ropes can alleviate the impact of seismic dynamics on the structure.

[0027] (3) The present invention is provided with connecting parts. The vertical connecting parts connect to the vertical precast columns, and the horizontal connecting parts connect to the horizontal precast columns to form a three-dimensional structural frame, which greatly improves the rigidity and load-bearing capacity of the overall structure. In addition, steel hoops are used between the connecting parts and the precast columns to effectively enhance the strength of the connection parts and prevent the connection parts from being damaged under stress.

[0028] (4) The present invention is equipped with a reinforcement component. Through the reinforcement body and the reinforcement channel, the precast columns and connectors can be effectively connected to form a whole and improve the structural bearing capacity. Under the action of dynamic forces such as earthquakes, the reinforcement component pulls the steel bars in the connector through the reinforcement channel in the reinforcement body, effectively preventing misalignment between precast columns. At the same time, the whole structure forms a mutually restrictive system, which can better disperse and transfer seismic forces during earthquakes and improve the seismic resistance of the structure.

[0029] (5) The present invention provides a reinforcing member, which is set between the connector and the reinforcing member. The frame structure is formed by the main board and the parallel arm. It is fixedly connected to the connector through the connecting hole, which effectively enhances the strength of the connection and improves the load-bearing capacity of the overall structure. At the same time, it can effectively transmit and transfer the tensile stress and shear stress between the vertical and horizontal connectors, preventing the connection from breaking or loosening. It can also better coordinate the relative movement of the vertical and horizontal connectors, which is conducive to dissipating and transferring seismic energy, thereby improving the seismic resistance of the structure.

[0030] (6) The combination of vertical and horizontal precast columns in this invention increases the load-bearing capacity and resistance to lateral displacement of the columns, enabling the columns to better withstand horizontal forces and seismic loads. The installation of connectors creates a stable connection between the precast columns, preventing misalignment or detachment of the columns and increasing the stability of the overall structure. Furthermore, the addition of reinforcements further enhances the load-bearing capacity and seismic performance of the precast columns, enabling the columns to better resist external loads and seismic forces. At the same time, the installation of reinforcements at the connectors increases the rigidity of the structure, making the connection more robust and stable, and improving the seismic performance of the overall structure.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1 As shown, a precast concrete column 1 reinforcement and anti-displacement structure includes: a plurality of precast columns 1, reinforcement members 2 connected to the plurality of precast columns 1, and connectors 3 disposed between the precast columns 1 and the reinforcement members 2. Through the multiple connections between the reinforcement members 2, connectors 3, and precast columns 1, the stability and load-bearing capacity of the precast concrete columns 1 can be significantly improved, reducing damage caused by external factors such as earthquakes and wind loads. The reinforcement members 2 and connectors 3 in this structure can be reused, reducing material waste. Furthermore, materials such as steel ropes and steel wire mesh reinforced polyethylene composite pipes also have a long service life and are environmentally friendly.

[0040] like Figure 2As shown, the connector 3 includes a vertical connector 31 and a horizontal connector 32; the vertical connector 31 includes a vertical connecting plate 311 connected to the longitudinal reinforcement 13 extending from the surface of the vertical precast column 11, and a first extension channel 312 disposed within the vertical connecting plate 311; the horizontal connector 32 includes a horizontal connecting plate 321 connected to the transverse reinforcement 14 extending from the surface of the transverse precast column 12, and a second extension channel 322 disposed within the horizontal connecting plate 321.

[0041] The vertical connecting plate 311 has a length of 500–1000 mm, a width of 200–300 mm, and a thickness of 20–30 mm; the vertical connecting plate 311 has 4–8 vertical extension channels with an inner diameter of Φ14–Φ25 mm. The horizontal connecting plate 321 has a length of 200–500 mm, a width of 200–300 mm, and a thickness of 20–30 mm; the horizontal connecting plate 321 has 4–8 horizontal extension channels with an inner diameter of Φ10–Φ16 mm.

[0042] The vertical connecting plate 311 extends with steel hoop 4 towards the vertical precast column 11 group, and the horizontal connecting plate 321 also extends with steel hoop 4 towards the horizontal precast column 12 group; both the vertical connecting plate 311 and the horizontal connecting plate 321 are provided with bolt connection holes for the longitudinal reinforcement 13 and the transverse reinforcement 14 to pass through, and are fastened with Φ20-Φ30mm bolts, nuts or concrete anchors as connecting parts 3.

[0043] The vertical connector 31 in connector 3 connects to the vertical precast column 11, and the horizontal connector 32 connects to the horizontal precast column 12, which can form a three-dimensional structural frame, greatly improving the rigidity and load-bearing capacity of the overall structure. In addition, steel hoop plates 4 are used between connector 3 and precast column 1 to effectively enhance the strength of the connection and prevent the connection from being damaged under stress.

[0044] like Figure 3 As shown, the precast column 1 includes: several vertical precast columns 11 and several horizontal precast columns 12, several longitudinal ribs 13 disposed in the vertical precast columns 11, several transverse ribs 14 disposed in the horizontal precast columns 12, and vertical tension pipes 15 and horizontal tension pipes 16 disposed inside the vertical precast columns 11 and horizontal precast columns 12 along their length direction; steel ropes are disposed inside both the vertical tension pipes 15 and horizontal tension pipes 16; the outer diameter of the steel ropes is equal to the inner diameter of the vertical tension pipes 15 and horizontal tension pipes 16; the vertical tension pipes 15 and horizontal tension pipes 16 are one of steel wire mesh reinforced polyethylene composite pipes, stainless steel pipes, or steel-plastic composite pipes.

[0045] The vertical precast column 11 and the horizontal precast column 12 are precast concrete and have rectangular or circular cross sections. The vertical precast column 11 contains 4 to 8 longitudinal steel bars with a diameter of 14 to 25 mm and a spacing of 100 to 150 mm; the horizontal precast column 12 contains 4 to 8 transverse steel bars with a diameter of 10 to 16 mm and a spacing of 100 to 150 mm.

[0046] Both the vertical precast column 11 and the horizontal precast column 12 are equipped with several tie bars 17. The vertical tie pipe 15 and the horizontal tie pipe 16 are fixedly connected to one side of the tie bars 17, and the other side of the tie bars 17 is fixedly connected to the precast column 1.

[0047] The vertical precast columns 11 and the horizontal precast columns 12 are equipped with Φ20mm tie bars 17, spaced at intervals of 300-500mm. The tie bars 17 are arranged at an angle, with the angle between the tie bars 17 and the horizontal direction being α. Where D is the width of precast column 1, H is the height of precast column 1, and R is the diameter of the tension duct. One end of the tension steel bar 17 is fixed to the outside of the tension duct, and the other end is fixed to the inside of the precast column 1.

[0048] The use of vertical precast columns 11 and horizontal precast columns 12, along with built-in longitudinal and transverse reinforcement bars 13 and 14, makes the structure more robust and effectively prevents the precast columns 1 from shifting or overturning under geological disasters such as earthquakes. At the same time, the built-in vertical and horizontal tension pipes 15 and steel cables inside the pipes enable three-dimensional connection of the precast columns 1, effectively improving the overall seismic resistance of the structure. The tension force of the steel cables can mitigate the impact of seismic dynamics on the structure.

[0049] like Figure 4 As shown, a reinforcing member 33 is provided at the connection between the vertical connector 31 and the horizontal connector 32. The reinforcing member 33 includes a first reinforcing plate 331 provided on the vertical connector 31 and a second reinforcing plate 332 provided on the horizontal connector 32. The first reinforcing plate 331 and the second reinforcing plate 332 are an integral structure.

[0050] Both the first reinforcing plate 331 and the second reinforcing plate 332 include: a main plate 333, a plurality of parallel arms 334 extending in the same direction on one side of the main plate 333, and a plurality of connecting holes 335 formed on the parallel arms 334; the connecting holes 335 on the parallel arms 334 are arranged in a horizontal array along the main line of the parallel arms 334.

[0051] The reinforcing plate is made of high-strength steel plate with a thickness of 15-20mm. The extended parallel arm 334 has a length of 200-350mm. The parallel arm 334 has 5-10 connecting holes 335 with a spacing of 20-70mm.

[0052] The reinforcing member 33 is set between the connector 3 and the reinforcing member 2, forming a frame structure through the main board 333 and the parallel arm 334. It is fixedly connected to the connector 3 using the connecting hole 335, which effectively enhances the strength of the connection and improves the load-bearing capacity of the overall structure. At the same time, it can effectively transmit and transfer the tensile stress and shear stress between the vertical and horizontal connectors 32, preventing the connection from breaking or loosening. It can also better coordinate the relative movement of the vertical and horizontal connectors 32, which is conducive to dissipating and transferring seismic energy, thereby improving the seismic resistance of the structure.

[0053] The reinforcement component 2 includes: a reinforcement body 21 that is detachably connected to the vertical connector 31 and the horizontal connector 32, and a plurality of reinforcement channels 22 formed inside the reinforcement body 21.

[0054] The reinforcement component 2, through the reinforcement body 21 and the reinforcement channel 22, can effectively connect the precast column 1 and the connector 3 to form a whole, thereby improving the structural bearing capacity. Under the action of dynamic forces such as earthquakes, the reinforcement component 2, through the reinforcement channel 22 in the reinforcement body 21, pulls the steel bars in the connector 3, effectively preventing misalignment between the precast columns 1. At the same time, it makes the whole structure form a mutually restrictive system, which can better disperse and transfer seismic forces during earthquakes, thereby improving the seismic resistance of the structure.

[0058] S3. Connecting reinforcement component 2: Connect the reinforcement body 21 to the vertical connector 31 and the horizontal connector 32, and ensure that the reinforcement channel 22 is aligned with the vertical tension pipe 15 and the horizontal tension pipe 16 in the precast column 1.

[0059] S4. Install the reinforcing plates: Place the first reinforcing plate 331 and the second reinforcing plate 332 on the surfaces of the vertical connector 31 and the horizontal connector 32 respectively, pass the steel rope through the precast column 1, the reinforcing member 2 and the connector 3, and tighten the steel rope to complete the installation.

[0060] In step S1, the precast column 1 is transported to the construction site, and the precast column 1 is placed in the predetermined position using a crane. The shape of the precast column 1 is checked to see if it meets the design requirements, such as whether the size and shape are standard. The verticality and horizontality errors are ensured to be below 1 / 1000 using a level and plumb line.

[0061] In step S4, a number of connection holes 335 are assembled on the parallel arm 334 via dry connectors to house the first reinforcing plate 331 and the second reinforcing plate 332 on the surfaces of the vertical connector 31 and the horizontal connector 32, respectively.
