A connection node between a concrete member and a steel support and an installation method thereof

Abstract

The present invention belongs to the technical field of concrete member-steel support, and specifically relates to a connection node between a concrete member and a steel support and an installation method thereof, which includes a frame body, a support steel rod, a fixing assembly, a hydraulic assembly and a straightening assembly. When an earthquake occurs, the corner position of the top beam column of the frame body is squeezed. If the earthquake intensity is small, when the support steel rod is tilted and compressed, the support steel rod moves along the sliding sleeve and squeezes the disc spring, so that the disc spring buffers the support steel rod, thereby preventing the earthquake from causing damage to the connection node of the frame body. If the earthquake intensity is large, the oblique movement of the support steel rod drives the transmission rod to rotate, so that the support steel rod provides tension to the support column and the lower frame beam through the transmission rod, and the tension direction is toward the support steel rod. At this time, the tension of the support steel rod keeps the lower frame beam and the support column at a right angle, suppressing the tendency of the overall deformation of the frame body into a parallelogram.

Description

Technical Field

[0001] The invention belongs to the technical field of concrete member-steel support, and specifically relates to a connection node between a concrete member and a steel support and an installation method thereof. Background Art

[0002] Reinforced concrete frame is a structural system built with concrete components. When the lateral stiffness of the reinforced concrete frame structure is insufficient, it is usually necessary to set up lateral force-resistant components, such as shear walls and steel supports, to increase its ability to resist horizontal loads. Since concrete is a brittle material, its seismic performance is poor. When performing seismic design, it is usually necessary to install steel supports to form a supporting frame structure.

[0003] The frame structure consists of an upper frame beam at the top, a lower frame beam at the bottom, and support columns connecting the upper frame beam and the lower frame beam. During an earthquake, the top beam-column corner of the upper frame beam is easily squeezed, causing the entire frame to gradually deform into a parallelogram. At this time, the frame will obliquely squeeze the steel support. Although the steel support of the existing technology can provide lateral support for the frame structure, most of the steel supports use rigid connection nodes. After being obliquely squeezed, the steel support is prone to buckling downward, which will affect its own supporting force. At the same time, the buckling of the steel support will damage the connection node between the lower frame beam and the support column. Summary of the invention

[0011] Preferably, the upper frame beam is connected to the side wall of the U-shaped support plate through a buffer assembly, and the buffer assembly includes a telescopic rod, one end of which is rotatably connected to the side wall of the upper frame beam, and the other end of the telescopic rod is rotatably connected to the inner wall of the U-shaped support plate.

[0012] Preferably, the buffer assembly further comprises an upper baffle and a lower baffle installed horizontally, and when the U-shaped support plate moves upward, the upper baffle and the lower baffle respectively abut against the top and the bottom of the telescopic rod cylinder.

[0018] Step S21: The supporting steel rod is connected to the input end of the hydraulic lever through a hydraulic rod, the output end of the hydraulic lever is connected to a U-shaped support plate through a push rod, and the U-shaped support plate is connected to the upper frame beam through a telescopic rod.

[0019] Beneficial effects of the present invention:

[0020] (1) When an earthquake occurs, the corner position of the top beam column of the frame body is squeezed, causing the frame body as a whole to gradually deform into a parallelogram. At this time, the frame body obliquely squeezes the supporting steel rod. If the earthquake intensity is small, when the supporting steel rod is tilted and compressed, the supporting steel rod slides along the installation sleeve. At this time, the supporting steel rod moves along the sliding sleeve and squeezes the disc spring, so that the disc spring buffers the supporting steel rod, thereby preventing the earthquake from damaging the connection node of the frame body. If the earthquake intensity is large, when the supporting steel rod is tilted and compressed, the oblique movement of the supporting steel rod drives the transmission rod to rotate, so that the supporting steel rod provides tension to the lower frame beam through the transmission rod and the bottom mounting plate, and the tension direction is toward the supporting steel rod; the supporting steel rod provides tension to the supporting column through the transmission rod and the side wall mounting plate, and the tension direction is also toward the supporting steel rod. At this time, the tension of the supporting steel rod keeps the lower frame beam and the supporting column at right angles, suppressing the tendency of the overall deformation of the frame body into a parallelogram.

[0021] (2) When a small earthquake occurs, the upper frame beam swings slightly under the influence of the earthquake wave. The upper frame beam squeezes the telescopic rod on one side of the upper frame beam to shrink it, and stretches the telescopic rod on the other side of the upper frame beam to lengthen it. When the upper frame beam swings in one direction, the telescopic rods on both sides of the upper frame beam will simultaneously exert a reaction force on the upper frame beam to cushion the swing of the upper frame beam. During this process, the bottom of the U-shaped support plate does not contact the upper frame beam, thereby avoiding the wear of the U-shaped support plate caused by the swing of the upper frame beam. When the intensity of the earthquake increases, the push rod pushes the U-shaped support plate upward, and the U-shaped support plate drives the telescopic rod to completely shrink and make the telescopic rod flush. At this time, the bottom of the U-shaped support plate contacts the upper frame beam, so that the U-shaped support plate clamps and fixes the upper frame beam, preventing the upper frame beam from swinging significantly, thereby reducing the damage caused by the large swing of the upper frame beam to the connection node between the upper frame beam and the support column, and further avoiding the phenomenon of the upper frame beam falling due to damage to the connection node between the upper frame beam and the support column.

[0022] (3) When an earthquake occurs, the upper frame beam swings under the action of the earthquake wave. At this time, the telescopic rod will buffer the upper frame beam to reduce the swing frequency of the upper frame beam and improve the stability of the upper frame beam. When the earthquake intensity is small, the telescopic rod can effectively prevent the upper frame beam from swinging and prevent the upper frame beam from damaging the connection node between the upper frame beam and the support column. When the earthquake intensity increases, the push rod pushes the U-shaped support plate upward, and the U-shaped support plate drives the telescopic rod to fully retract and put the telescopic rod in a flush state. When the telescopic rod moves to a horizontal state, the upper baffle on the upper frame beam limits the top of the telescopic rod, and the lower baffle on the U-shaped support plate limits the bottom of the telescopic rod. The telescopic rod is kept in a horizontal state. At this time, the bottom of the U-shaped support plate contacts the bottom surface of the upper frame beam. When the earthquake further increases, as the earthquake intensifies, the hydraulic oil in the hydraulic chamber continues to squeeze the push rod, so that the push rod drives the U-shaped support plate and the upper frame beam to lift up, thereby protecting the upper frame beam and reducing the probability of the upper frame beam falling.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0033] See also Figure 1-Figure 4 , a connection node between a concrete member and a steel support, comprising a frame body 1 and a support steel rod 2, the frame body 1 comprising a lower frame beam 11, an upper frame beam 13 and a support column 12 connecting the lower frame beam 11 and the upper frame beam 13, a fixing component 3 and a straightening component 4 are installed at the corner of the lower frame beam 11 and the support column 12, one end of the support steel rod 2 is inserted into the fixing component 3 and connected to the straightening component 4; another fixing component 3 and a hydraulic component 5 are installed at the corner of the support column 12 and the upper frame beam 13, the other end of the support steel rod 2 is inserted into another fixing component 3 and connected to the hydraulic component 5;

[0034] The straightening assembly 4 includes a side wall mounting plate 41, a bottom mounting plate 42 and a transmission rod 43. The bottom mounting plate 42 and the side wall mounting plate 41 are respectively installed on the lower frame beam 11 and the support column 12. The side wall mounting plate 41 and the bottom mounting plate 42 are respectively connected to the two sides of the supporting steel rod 2 through the transmission rod 43.

[0035] Two fixing components 3 and two ribs 6 are respectively installed on two opposite oblique angles of the frame body 1. The mounting sleeves 31 on the two fixing components 3 are respectively sleeved on the two ends of the supporting steel rod 2. When the supporting steel rod 2 is obliquely compressed, the supporting steel rod 2 can slide along the direction of the mounting sleeve 31, and the supporting steel rod 2 is buffered by the straightening component 4; the two ribs 6 can improve the overall stability of the frame body 1. One of the ribs 6 is connected to one end of the supporting steel rod 2 through the hydraulic component 5, and the other rib 6 is connected to the other end of the supporting steel rod 2 through the disc spring 44. When the supporting steel rod 2 is compressed, the hydraulic component 5 can support the upper frame beam 13 to prevent the upper frame beam 13 from falling during an earthquake.

[0036] When an earthquake occurs, the top beam and column corners of the frame body 1 are squeezed, causing the frame body 1 to gradually deform into a parallelogram as a whole. At this time, the frame body 1 obliquely squeezes the supporting steel rod 2, causing the supporting steel rod 2 to slide along the mounting sleeves 31 on the lower frame beam 11 and the supporting column 12. At this time, the supporting steel rod 2 moves obliquely along the mounting sleeves 31. During the movement of the supporting steel rod 2, the transmission rod 43 is driven to rotate, causing the supporting steel rod 2 to provide a pulling force to the lower frame beam 11 through the transmission rod 43 and the bottom mounting plate 42, and the pulling force is directed toward the supporting steel rod 2; the supporting steel rod 2 provides a pulling force to the supporting column 12 through the transmission rod 43 and the side wall mounting plate 41, and the pulling force is also directed toward the supporting steel rod 2. At this time, the pulling force of the supporting steel rod 2 keeps the lower frame beam 11 and the supporting column 12 at a right angle, thereby suppressing the tendency of the frame body 1 to deform into a parallelogram as a whole.

[0037] See also Figure 4 Two ribs 6 are respectively installed on the two opposite diagonals of the frame body 1, one of the ribs 6 is connected to the hydraulic assembly 5, and a sliding sleeve 7 is installed on the other rib 6. The sliding sleeve 7 is connected to the supporting steel rod 2 through a disc spring 44, and the sliding sleeve 7 is slidably matched with the supporting steel rod 2.

[0038] When the earthquake intensity is relatively small, the supporting steel rod 2 is tilted and compressed, and the supporting steel rod 2 slides along the mounting sleeve 31. At this time, the supporting steel rod 2 moves along the sliding sleeve 7 and squeezes the disc spring 44, so that the disc spring 44 buffers the supporting steel rod 2 to prevent small-frequency earthquakes from causing damage to the connection nodes of the frame body 1.

[0039] See also Figure 2 and Figure 4 The fixing assembly 3 includes a mounting sleeve 31 and a connecting plate 32. The connecting plate 32 is connected to the frame body 1 through a reinforcing anchor bar 8. The mounting sleeve 31 is installed on the connecting plate 32. The two ends of the supporting steel rod 2 are respectively slidably matched with the mounting sleeve 31.

[0040] Specifically, the side wall mounting plate 41 and the bottom mounting plate 42 are respectively connected to the support column 12 and the lower frame beam 11 through the reinforcing anchor bars 8 .

[0041] By welding the reinforcing anchor bars 8 on the side wall mounting plate 41 and the bottom mounting plate 42, firstly drilling holes on the support column 12 and the lower frame beam 11, installing the reinforcing anchor bars 8 in the holes of the support column 12 and the lower frame beam 11, and then grouting, the installation of the side wall mounting plate 41 and the bottom mounting plate 42 is completed. The connection of the side wall mounting plate 41 and the bottom mounting plate 42 on the frame body 1 of the present invention can reduce the damage to the reinforced concrete structure nodes and maintain the bearing capacity of the original structure.

[0042] See also Figure 5-Figure 7The hydraulic assembly 5 includes a hydraulic lever 51 and a push rod 53. The hydraulic lever 51 is fixedly installed on the rib platform 6. A hydraulic cavity 52 is provided in the hydraulic lever 51. A hydraulic rod 54 is installed at one end of the supporting steel rod 2. The hydraulic rod 54 is inserted into the input end of the hydraulic cavity 52 for sliding fit. The output end of the hydraulic cavity 52 is connected to the push rod 53. The push rod 53 is installed with a U-shaped support plate 55, and the U-shaped support plate 55 is sleeved on the upper frame beam 13.

[0043] When an earthquake occurs, the upper frame beam 13 is affected by the earthquake wave and swings. The swing of the upper frame beam 13 may damage the connection node between the upper frame beam 13 and the support column 12. Figure 7 When the upper frame beam 13 is swinging, the telescopic rod 93 will buffer the upper frame beam 13 to reduce the swing frequency of the upper frame beam 13 and improve the stability of the upper frame beam 13. When the earthquake intensity is small, the telescopic rod 93 can effectively prevent the upper frame beam 13 from swinging and prevent the upper frame beam 13 from damaging the connection node between the upper frame beam 13 and the support column 12; when the earthquake intensity increases, the oblique extrusion of the frame body 1 on the support steel rod 2 becomes more serious, see Figure 5 As the frame body 1 squeezes the supporting steel rod 2 obliquely, the hydraulic lever 51 moves along the direction of the supporting steel rod 2. At this time, the hydraulic rod 54 on the supporting steel rod 2 squeezes the hydraulic oil in the hydraulic chamber 52, so that the hydraulic oil in the hydraulic chamber 52 pushes the push rod 53 to move toward the upper frame beam 13. At this time, the U-shaped support plate 55 drives the telescopic rod 93 to move upward, so that the telescopic rod 93 moves from an inclined state to a horizontal state. When the telescopic rod 93 moves to a horizontal state, the upper baffle plate 91 on the upper frame beam 13 limits the top of the telescopic rod 93, and the lower baffle plate 92 on the U-shaped support plate 55 limits the bottom of the telescopic rod 93. The telescopic rod 93 is kept in a horizontal state. At this time, the bottom of the U-shaped support plate 55 contacts the bottom surface of the upper frame beam 13. When the earthquake further increases, as the earthquake intensifies, the hydraulic oil in the hydraulic chamber 52 continues to squeeze the push rod 53, causing the push rod 53 to drive the U-shaped support plate 55 and the upper frame beam 13 to lift up, thereby protecting the upper frame beam 13 and reducing the probability of the upper frame beam 13 falling.

[0044] See also Figure 7 The upper frame beam 13 is connected to the side wall of the U-shaped support plate 55 through a buffer assembly 9. The buffer assembly 9 includes a telescopic rod 93. One end of the telescopic rod 93 is rotatably connected to the side wall of the upper frame beam 13, and the other end of the telescopic rod 93 is rotatably connected to the inner wall of the U-shaped support plate 55.

[0045] Specifically, the buffer assembly 9 further includes an upper baffle 91 and a lower baffle 92 which are installed horizontally. When the U-shaped support plate 55 moves upward, the upper baffle 91 and the lower baffle 92 respectively abut against the top and bottom of the cylinder of the telescopic rod 93 .

[0046] When the earthquake intensity is relatively low, the upper frame beam 13 is affected by the earthquake wave and swings slightly. When the upper frame beam 13 swings, the upper frame beam 13 will squeeze the telescopic rod 93 on one side of the upper frame beam 13 to shrink it, and the upper frame beam 13 will stretch the telescopic rod 93 on the other side of the upper frame beam 13 to lengthen it. When the upper frame beam 13 swings in one direction, the telescopic rods 93 on both sides of the upper frame beam 13 will simultaneously apply a reaction force to the upper frame beam 13 to cushion the swing of the upper frame beam 13; the same applies when the upper frame beam 13 swings in the opposite direction. During this process, the bottom of the U-shaped support plate 55 does not contact the upper frame beam 13, thereby preventing the swing of the upper frame beam 13 from wearing the U-shaped support plate 55. When the intensity of the earthquake increases, the push rod 53 pushes the U-shaped support plate 55 upward, and the U-shaped support plate 55 drives the telescopic rod 93 to completely retract and make the telescopic rod 93 in a flush state. At this time, the bottom of the U-shaped support plate 55 contacts the upper frame beam 13, so that the U-shaped support plate 55 clamps and fixes the upper frame beam 13, preventing the upper frame beam 13 from swinging sharply, thereby reducing the damage to the connection node between the upper frame beam 13 and the support column 12 caused by the large swing of the upper frame beam 13, and further avoiding the phenomenon of the upper frame beam 13 falling off due to damage to the connection node between the upper frame beam 13 and the support column 12.

[0047] See also Figure 1-Figure 5 As shown, the present invention is a method for installing a connection node between a concrete member and a steel support member, and the method is applied to the connection node between the concrete member and the steel support member as described in the above embodiment, and the method comprises the following steps:

[0048] Step S1: Install two ribs 6 at two diagonal corners of the frame body 1 respectively, install the hydraulic assembly 5 on the rib 6 at the top of the frame body 1, and install the disc spring 44 on the other rib 6;

[0049] Step S2: The two fixing components 3 are respectively installed at two diagonal corners of the frame body 1, and the two ends of the support steel rod 2 are sleeved on the installation sleeve 31, one end of the support steel rod 2 is connected to one of the ribs 6 through the hydraulic component 5, and the other end of the support steel rod 2 is connected to the other rib 6 through the disc spring 44;

[0050] Step S3: Install the side wall mounting plate 41 and the bottom mounting plate 42 on the support column 12 and the lower frame beam 11 respectively, and then connect the side wall mounting plate 41 and the bottom mounting plate 42 to both sides of the support steel rod 2 respectively through the transmission rod 43.

[0051] like Figure 5-Figure 7 As shown, as a preferred embodiment of the present invention, step S2 specifically includes the following steps:

[0052] Step S21: The supporting steel rod 2 is connected to the input end of the hydraulic lever 51 through the hydraulic rod 54, the output end of the hydraulic lever 51 is connected to the U-shaped support plate 55 through the push rod 53, and the U-shaped support plate 55 is connected to the upper frame beam 13 through the telescopic rod 93.

[0053] The implementation principle of the present invention is:

[0054] When an earthquake occurs, the corner of the top beam of the frame body 1 is squeezed, causing the frame body 1 to gradually deform into a parallelogram. At this time, the frame body 1 obliquely squeezes the support steel rod 2. If the earthquake intensity is small, when the support steel rod 2 is tilted and compressed, the support steel rod 2 slides along the installation sleeve 31. At this time, the support steel rod 2 moves along the sliding sleeve 7 and squeezes the disc spring 44, so that the disc spring 44 buffers the support steel rod 2, thereby preventing the earthquake from causing damage to the connection node of the frame body 1. If the earthquake intensity becomes larger and the supporting steel rod 2 is tilted and compressed, the supporting steel rod 2 moves obliquely to drive the transmission rod 43 to rotate, so that the supporting steel rod 2 provides a pulling force to the lower frame beam 11 through the transmission rod 43 and the bottom mounting plate 42, and the pulling force is directed toward the supporting steel rod 2; the supporting steel rod 2 provides a pulling force to the supporting column 12 through the transmission rod 43 and the side wall mounting plate 41, and the pulling force is also directed toward the supporting steel rod 2. At this time, the pulling force of the supporting steel rod 2 keeps the lower frame beam 11 and the supporting column 12 in a right-angle state, thereby suppressing the tendency of the overall frame body 1 to deform into a parallelogram.

[0055] When a small earthquake occurs, the upper frame beam 13 is affected by the earthquake wave and swings slightly. When the upper frame beam 13 swings, the upper frame beam 13 squeezes the telescopic rod 93 on one side of the upper frame beam 13 to shrink it, and the upper frame beam 13 stretches the telescopic rod 93 on the other side of the upper frame beam 13 to lengthen it. When the upper frame beam 13 swings in one direction, the telescopic rods 93 on both sides of the upper frame beam 13 will simultaneously apply a reaction force to the upper frame beam 13 to buffer the swing of the upper frame beam 13, so as to reduce the swing frequency of the upper frame beam 13, improve the stability of the upper frame beam 13, and prevent the upper frame beam 13 from causing damage to the connection node between the upper frame beam 13 and the support column 12; the same applies when the upper frame beam 13 swings in the opposite direction. In this process, the bottom of the U-shaped support plate 55 does not contact the upper frame beam 13, thereby preventing the swing of the upper frame beam 13 from wearing the U-shaped support plate 55.

[0056] When the earthquake is large, the oblique compression of the frame body 1 on the supporting steel rod 2 becomes more serious, see Figure 5As the frame body 1 squeezes the supporting steel rod 2 obliquely, the hydraulic lever 51 moves along the supporting steel rod 2. At this time, the hydraulic rod 54 on the supporting steel rod 2 squeezes the hydraulic oil in the hydraulic chamber 52, so that the hydraulic oil in the hydraulic chamber 52 pushes the push rod 53 to move toward the upper frame beam 13. The U-shaped support plate 55 on the push rod 53 drives the telescopic rod 93 to fully retract and put the telescopic rod 93 in a flush state. At this time, the bottom of the U-shaped support plate 55 contacts the bottom surface of the upper frame beam 13. Since the telescopic rod 93 is in a fully retracted state, the U-shaped support plate 55 can prevent the upper frame beam 13 from swinging significantly, thereby reducing the damage caused by the large swing of the upper frame beam 13 to the connection node between the upper frame beam 13 and the support column 12. When the earthquake further increases, as the earthquake intensifies, the hydraulic oil in the hydraulic chamber 52 continues to squeeze the push rod 53, so that the push rod 53 drives the U-shaped support plate 55 and the upper frame beam 13 to lift up, thereby protecting the upper frame beam 13 and reducing the probability of the upper frame beam 13 falling.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
