Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a construction method for independent column-connecting beam joints. Background Technology

[0002] In recent years, with the continuous development of the construction industry, various construction techniques for strengthening old structural components have gradually matured. In particular, the construction techniques for strengthening concrete columns, including conventional methods such as increasing the cross-section, replacing concrete, bonding steel, and carbon fiber reinforcement, have been widely applied to various strengthening projects.

[0003] Currently, the independent column-connected beam assembly method has been widely used in many fields both domestically and internationally, such as bridges, architecture, and water conservancy. In the bridge field, it is often used to reinforce bridge piers, bridges, abutments, and other structures; in the architecture field, it is often used to reinforce building columns, beams, slabs, and other structures; and in the water conservancy field, it is often used to reinforce dams, dikes, and other structures.

[0004] The independent column-connecting beam assembly method is a reinforcement method used to strengthen the connection between columns and beams in concrete structures. This method mainly constructs connection support points by connecting independent columns and connecting beams, utilizing the high strength of the independent columns and the synergistic stress-bearing characteristics of the connecting beams to improve the load-bearing capacity at the connection, thereby enhancing the seismic performance and load-bearing capacity of the entire structure. In contrast, existing technologies typically require repeated position checks when hoisting the corresponding connection between the independent columns and connecting beams, and the overall hoisting process is limited by space requirements, resulting in complex construction and low efficiency.

[0029] Step 1: After confirming that the complete independent column meets the load-bearing wind resistance test standard, construct the connection node model according to the connection dimensions between the top of the complete independent column and the bottom of the connecting beam;

[0030] Step 2: Divide the connection node model into installation groups to facilitate the subsequent installation of connection nodes;

[0038] Furthermore, the complete independent column comprises multiple sets of independent column components. The interior of each independent column component includes linear reinforcing bars and ring reinforcing bars. The linear reinforcing bars protrude 10-15cm from the top and bottom of the independent column component. The independent column components are spliced ​​and installed together through the connecting guide groove. The connecting guide groove includes an upper guide groove and a lower guide groove. The upper guide groove includes a first top surface and a first bottom surface. A first recessed platform is provided on the first top surface, and multiple grooves are provided on the first recessed platform. Multiple connecting columns are provided on the first bottom surface. The connecting columns are used to cooperate with the linear reinforcing bars protruding from the top of the independent column component to achieve a reinforcing connection effect. A first grouting hole is provided at one end of the upper guide groove near the first top surface. The first grouting hole is connected to the groove through a first grouting channel. A second grouting hole is provided at one end of the upper guide groove near the first bottom surface. The second grouting hole is connected to the first bottom surface through a second grouting channel.

[0039] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by setting multiple sets of independent column components and assembling them into complete independent columns, the construction difficulty is reduced. Furthermore, during the splicing process, by aligning the upper guide groove on the top of the independent column component with the lower guide groove position of the upper independent column component, the time for position verification can be effectively shortened, and installation misalignment can be prevented from damaging the structural strength.

[0040] Furthermore, the lower guide channel includes a second top surface and a second bottom surface. The second top surface is also provided with a plurality of connecting columns. The connecting columns are used to cooperate with the linear steel bars exposed at the bottom of the independent column members to achieve a reinforcing connection effect. The second bottom surface is provided with a boss. The boss is provided with a plurality of connecting protrusions. The boss is used to cooperate with the first recessed platform on the upper guide channel at the top of the adjacent set of independent column members. The connecting protrusions are used to cooperate with the grooves on the first recessed platform, thereby achieving the effect of fixing and installing the two adjacent sets of independent column members. The lower guide channel is provided with a third grouting hole at one end near the second top surface. The third grouting hole is connected to the second top surface through a third grouting channel.

[0041] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By setting up upper and lower guide channels, when constructing the connecting guide channel on the independent column member, the top of the current independent column member is made to contact and install with the first bottom surface of the upper guide channel. At this time, the linear steel bar exposed at the top of the independent column member intersects with the connecting column on the first bottom surface. Then, the bottom end of the independent column member is made to contact and install with the second top surface of the lower guide channel. At this time, the linear steel bar exposed at the bottom end of the independent column member intersects with the connecting column on the second top surface. The independent column members with the completed connecting guide channels are installed in sequence to form a complete independent column.

[0042] Furthermore, the top of the complete independent column is fixedly connected to the independent column connection node by bolts. The independent column connection node includes a beam connection end, an independent column connection end, and an embedded matching installation end. The independent column connection end is fixedly connected to the top of the complete independent column. The independent column connection end is provided with two sets of matching grooves. The beam connection end is fixedly connected to the connecting beam by anchor bolts. The two ends of the beam connection end are provided with matching protrusions.

[0043] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting independent column connection nodes to connect complete independent columns and connecting beams, by setting beam connection ends to connect with connecting beams, by setting independent column connection ends to connect with complete independent columns, and by embedding matching installation ends to fix the independent column connection ends and embedded matching installation ends at the corresponding positions of beam connection ends and independent column connection ends, the assembly accuracy can be effectively improved, the maintainability of the connection points can be improved, and the installation and construction efficiency can be improved.

[0044] Furthermore, an embedded matching installation end is provided between the beam connection end and the independent column connection end. The embedded matching installation end is provided with a matching groove adapted to the matching protrusion. Both the embedded matching installation end and the matching protrusion are provided with threaded grooves. The threaded grooves are used to fix the anchor bolts. The embedded matching installation end is fixedly connected to the matching protrusion and the independent column connection end by anchor bolts.

[0045] Compared with existing technologies, the beneficial effects of the construction method for independent column connecting beam nodes provided by this invention are as follows: By setting multiple sets of independent column components and assembling them into complete independent columns, the construction difficulty is reduced. Furthermore, during the splicing process, by aligning the upper guide groove on the top of the independent column component with the lower guide groove of the upper independent column component, the time for position verification can be effectively shortened, preventing installation misalignment from damaging the structural strength. By setting upper and lower guide grooves, when constructing the connecting guide groove on the independent column component, the top of the current independent column component contacts the first bottom surface of the upper guide groove. At this time, the linear reinforcing bars exposed at the top of the independent column component intersect with the connecting columns on the first bottom surface. Then, the bottom end of the independent column component is installed in contact with the second top surface of the lower guide channel. At this time, the linear steel bar exposed at the bottom end of the independent column component intersects with the connecting column on the second top surface. The independent column components that have completed the connecting guide channel are installed in sequence to form a complete independent column. By setting independent column connection nodes to connect the complete independent column and the connecting beam, by setting beam connection ends to connect with the connecting beam, by setting independent column connection ends to connect with the complete independent column, and by embedding matching installation ends, the independent column connection ends are fixedly connected to the embedded matching installation ends according to the positions of the beam connection ends and the independent column connection ends. This can effectively improve the assembly accuracy, improve the maintainability of the connection, and improve the installation and construction efficiency. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0055] like Figure 5 The diagram shown is a flowchart of a construction method for an independent column-connected beam joint provided by the present invention, including the following steps:

[0056] S10: Compile precast reinforced concrete segmented independent column components;

[0057] S20: Construct a complete independent column by building a connecting guide groove to install the corresponding independent column;

[0058] S30: Conduct wind stress testing on complete independent columns and test the connection strength of independent columns;

[0059] S40: Prefabricate independent column connection nodes according to the dimensions of the top of the complete independent column;

[0060] S50: Assemble a complete independent column at the bottom position of the corresponding connecting beam, and fix the independent column and the connecting beam through the connecting node.

[0061] Optionally, in the above technical solution, the specific steps for preparing precast reinforced concrete segmented independent column components include:

[0062] First, obtain the full-load bearing stress value of the connecting beam according to the design drawings;

[0063] Furthermore, the distance between the connecting beam and the base surface and the diameter of the bottom end of the connecting beam are measured, and the segmented dimensional parameters of the independent column are designed based on the distance parameters;

[0064] Then, select the appropriate size and grade of steel bars according to the design parameters;

[0065] Linear steel bars are used for radial support. The linear steel bars are bent into ring steel bars by a bending machine. The steel bars are tied in sections. The length of the radial support steel bars should extend 15-20cm beyond the top and bottom ring steel bars. The contact points are welded and fixed. The welded steel bar structure is placed into a mold made according to the design parameters of the segmented independent column component and concrete is poured in. After the concrete dries, the independent column component is formed.

[0066] The dimensional design of independent column members must take into account the soil's bearing capacity. Generally, the lower the soil's bearing capacity, the larger the required column size, which can be calculated using the following formula:

[0067] Column dimensions = (Bridge bearing capacity × Soil bearing capacity coefficient) ÷ Seismic resistance coefficient

[0068] Among them, the column size is the diameter of the independent column member in m, the bridge bearing capacity is the bearing capacity value selected when designing the bridge, and the seismic capacity coefficient can vary depending on the different uses; for example, if a rest or construction platform is constructed by connecting beams, the seismic capacity coefficient is 0.8; if it is necessary to support the weight of the bridge, the seismic capacity coefficient is 1.0.

[0069] Furthermore, in the above technical solution, the specific steps for constructing a complete independent column by building a connecting guide groove to correspond to the installation of the independent column include:

[0070] First, connecting guide grooves are constructed sequentially at the top of the prefabricated segmented independent column components, and connecting protrusions are constructed at the bottom.

[0071] The connecting guide groove includes an upper guide groove. The first bottom surface of the upper guide groove is inserted into the top of the independent column component. At this time, the connecting column on the first bottom surface and the linear steel bars exposed at the top of the independent column component are intersected. The viscous concrete coating is injected through the second grouting hole using a grouting device. The viscous concrete coating enters the space between the top surface and the first bottom surface of the independent column component through the second grouting channel, filling the gaps around the exposed linear steel bars and the connecting column. After the viscous concrete coating dries completely, the upper guide groove is fixed.

[0072] The connecting protrusion is the lower guide groove. Similarly, the second top surface of the lower guide groove is inserted into the bottom end of the independent column component. At this time, the connecting column on the second top surface and the exposed linear steel bars at the bottom end of the independent column component are intertwined. The viscous concrete coating is injected through the third grouting hole. The viscous concrete coating enters the space between the bottom surface of the independent column component and the second top surface through the third grouting channel, filling the gaps around the exposed linear steel bars and the connecting column. After the viscous concrete coating dries, the lower guide groove is fixed.

[0073] Then, install the adjacent two segmented independent column components according to the corresponding guide groove and connecting protrusion positions to prevent misalignment during installation.

[0074] After all the segmented independent column components are installed, a complete independent column is formed.

[0075] Furthermore, in the above technical solution, the specific steps for testing the wind stress resistance of the complete independent column and testing the connection strength of the independent column include:

[0076] First, a complete independent column is assembled in a wind tunnel laboratory. Pressure is applied to the upper and lower ends of the complete independent column through a load-applying platform. The applied pressure value is the maximum bearing capacity designed for the bridge.

[0077] An accelerometer was placed on each section of the complete independent column, and then the test wind tunnel was turned on to simulate the effect of different levels of external wind force on the strength of the complete independent column, with the wind force level increasing step by step.

[0078] According to the design calibration parameters, the wind stress of the complete independent column was tested, and the displacement change data detected by the acceleration sensor at the same time under different wind force levels were recorded. The data were then organized and recorded.

[0079] Among them, the design calibration parameters are the minimum standard of ideal displacement for each segment of an independent column in a complete independent column;

[0080] Regularly observe and test the condition of the complete independent column, and fully record the stress value, deformation amount, and cracking data of the independent column.

[0081] Furthermore, in the above technical solution, the specific steps for prefabricating independent column connection nodes based on the dimensions of the top of the complete independent column include:

[0082] First, after confirming that the complete independent column meets the load-bearing wind resistance test standard, construct the independent column connection node model based on the connection dimensions between the top of the complete independent column and the bottom of the connecting beam. By measuring the dimensional values ​​of the top of the complete independent column and the bottom of the connecting beam, use 3D modeling software to create a 3D model of the independent column connection node based on the measured dimensions.

[0083] Then, the 3D model of the independent column connection node is modularized, and the independent column connection node model is divided into installation groups to facilitate the subsequent installation of the independent column connection node.

[0084] Subsequently, casting production is carried out based on the grouped and split independent column connection node model to obtain the independent column connection node.

[0085] Furthermore, in the above technical solution, the specific steps for assembling the complete independent column at the bottom position of the connecting beam and fixing the independent column to the connecting beam through the connecting node include:

[0086] First, the vertical installation position is calibrated at the bottom of the connecting beam using a calibration instrument, and then the complete independent column is assembled according to the installation position.

[0087] Then, the bottom of the complete independent column is reinforced and connected to the base surface. After anchoring the bottom group of independent column components of the complete independent column to the base surface boss, a reinforcement mold is set up and filled with concrete to construct the base of the complete independent column.

[0088] The specific steps for connecting the top of a complete independent column to the bottom of a connecting beam using independent column connection nodes include:

[0089] Step 1: Fix the beam connection end of the independent column connection node to the bottom end of the connecting beam using anchor bolts;

[0090] Step 2: Connect the independent column connection end of the independent column connection node to the groove on the first protrusion of the independent column component at the top of the complete independent column through the bottom connecting protrusion. Use a reinforcing anchor to fix it in one step. Inject viscous concrete coating into the first grouting hole of the independent column component at the top of the complete independent column. After the viscous concrete coating dries completely, the connection end of the independent column is fixed to the top of the complete independent column.

[0091] Step 3: Embed and install the embedded matching installation end between the independent column connection end and the beam connection end, and fix the embedded matching installation end to the independent column connection end and the beam connection end respectively by anchor bolts.

[0092] A viscous concrete coating is added inside the connecting guide groove of the complete independent column to further enhance the overall strength of the complete independent column. The viscous concrete coating is injected into the first grouting hole of each group of independent column components of the complete independent column. The viscous concrete coating enters the groove through the first grouting channel and fills the gap around the connection between the groove and the connecting protrusion. After the viscous concrete coating dries, the overall strength of the complete independent column is further strengthened.

[0093] Step 5: Complete the assembly of the connection nodes between the independent columns and the connecting beams.

The second bottom surface 20 is provided with a boss, and a plurality of connecting protrusions 21 are provided on the boss. The boss is used to cooperate with the first recess 15 on the upper guide channel 11 at the top of the adjacent set of independent column members 10.

The lower guide channel 12 is provided with a third grouting hole 22 at one end near the second top surface 19. The third grouting hole 22 is connected to the second top surface 19 through a third grouting channel.
