Description

Technical Field

[0001] The invention belongs to the technical field of seawater-sand concrete nodes, in particular to an assembled FRP bar reinforced seawater-sand concrete node. Background Art

[0002] Precast concrete has become the new favorite in the construction industry for its low cost and excellent performance. At present, the beams and columns of precast assembled concrete structures are prefabricated in factories, and the connection between beams and columns generally adopts the method of secondary pouring on site. The precast FRP bar reinforced seawater and sea sand concrete beams and columns through this method require additional tools and supports on site to assist in construction. The installation accuracy requirements are high, the assembly is relatively inconvenient, which is not conducive to the force transmission at the connection nodes, and the solidification time after the secondary pouring is long.

[0004] When the above scheme is implemented, the crossbeam needs to be inserted into the prefabricated fixed steel trough. This process requires the use of lifting equipment to lift the crossbeam, and the end of the crossbeam is suspended on one side of the prefabricated fixed steel trough. Secondly, the end of the crossbeam is stably inserted into the prefabricated fixed steel trough, and it is necessary to ensure that the end of the crossbeam is directly opposite to the port of the prefabricated fixed steel trough. However, when the crossbeam is actually lifted, the docking deviation between the end of the crossbeam and the port of the prefabricated fixed steel trough is large, and staff are required to assist in observation and auxiliary correction. Therefore, the process needs to be repeatedly proofread, which takes a long time and is cumbersome to operate, affecting the installation efficiency of the crossbeam. For this reason, the present invention provides an assembled FRP bar reinforced seawater and sea sand concrete node. Summary of the invention

[0007] The two sets of plate bodies 1 are driven toward each other, and the two sets of plate bodies 1 move toward the two sides of the beam respectively, so that the two sides of the beam are squeezed by the two sets respectively, thereby clamping the beam in the middle of the supporting plate mechanism, and then the two sets of rocker arms are driven at the same time, so that the rocker arms deflect around the rotating shaft as the axis, and at the same time the rocker arms drive the plate body 2 to flip toward the beam, continue to flip the rocker arms, and assist in adjusting the position of the beam until the flipped plate body 2 fits with the upper end surface of the plate body 1, so that the plate body 2 flips down and presses down to correct the end of the beam.

[0009] The movable plate slides along the inner cavity of the L-shaped plate, and at the same time, the movable plate drives the two groups of pins to slide along the two groups of disguised slide grooves respectively. During the sliding of the pins along the disguised slide grooves, the pins squeeze the inner wall of the turning section of the disguised slide groove, so that the two groups of receiving plates move toward each other in the inner cavity of the L-shaped plate. At the same time, the receiving plate drives the plate body one through the guide column, so that the two groups of plate bodies one also move toward each other until the pins are offset from the turning section of the disguised slide groove, thereby realizing the clamping correction of the ends of a pair of beams of the above-mentioned two groups of plate bodies.

[0010] Preferably, the support plate mechanism further comprises: a receiving mechanism, which is used to drive the swing rod to flip, and the receiving mechanism comprises: an insertion rod, a rectangular hole is provided on one side of the plate body, the insertion rod is inserted into the rectangular hole, a roller is screwed on one end of the insertion rod, and an axis 1 is fixed on the other end of the insertion rod, a rectangular slide groove is provided on the swing rod, the rectangular slide groove is slidably connected to the axis 1, two groups of avoidance grooves 2 are symmetrically provided on the movable plate, an inverted inclined surface is provided in the avoidance groove 2, the roller is rollingly connected to the inverted inclined surface, an avoidance groove 1 is provided on one side of the plate body, a U-shaped spring piece is provided in the avoidance groove 1, and the U-shaped spring piece is closely attached to the swing rod;

At the same time, shaft one squeezes the inner wall of the rectangular slide groove to flip the rocker rod, thereby realizing the flipping of the above-mentioned plate body 2 to press down the end of the correction beam. Secondly, the setting of the roller reduces the friction between one end of the insertion rod and the inverted slope, thereby reducing the wear between the end of the insertion rod and the inverted slope.

[0012] Preferably, the support plate mechanism also includes: a limiting mechanism, which is used to limit the crossbeam, and the limiting mechanism includes: a driving rod, one end of the driving rod is fixedly connected to the movable plate, an L-shaped rod fixedly connected to the other end of the driving rod, a fixing plate plugged into the L-shaped rod, a spring sleeved on the L-shaped rod, a movable sleeve fixedly connected to the fixing plate, a rotating tube screwed in the movable sleeve, and a limiting plate fixed to the end of the rotating tube, a guide hole is provided on the fixing plate, the L-shaped rod is slidably connected to the guide hole, a spiral groove is provided on the rotating tube, the end of the L-shaped rod is slidably connected to the spiral groove, two groups of arc sliding grooves are symmetrically provided on both sides of the L-shaped plate, the movable sleeve is slidably connected to the arc sliding groove together with the limiting plate, two groups of limiting sliding grooves are symmetrically provided on both sides of the end of the crossbeam, limiting grooves are provided in the limiting sliding grooves, the movable sleeve is inserted into the limiting sliding groove together with the limiting plate, and the limiting plate is clamped in the limiting groove;

[0013] The movable sleeve is inserted into the limiting groove together with the limit plate until the limit plate reaches the bottom of the limit groove and cannot move. At this time, the driving rod pushes the L-shaped rod to slide along the guide hole on the fixed plate and compresses the spring. At the same time, the end of the L-shaped rod slides along the spiral groove on the rotating tube. As the end of the L-shaped rod slides along the spiral groove, the rotating tube will rotate, and the rotating tube drives the limit plate to rotate in the limit plate. After rotation, the limit plate deviates from the original slot position of the limit groove, so that the limit plate is limited in the limit groove, thereby limiting the crossbeam to the L-shaped plate.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. Drive the two sets of plate bodies one in opposite directions, and the two sets of plate bodies one move toward the two sides of the beam respectively, so that the two sides of the beam are squeezed by the two sets respectively, thereby clamping the beam in the middle of the support plate mechanism, and then drive the two sets of swing rods at the same time, so that the swing rods deflect with the rotation axis as the axis, and at the same time the swing rods drive the plate body two to flip toward the beam. At this time, if the upper end surface of the beam is not flush with the upper end surface of plate body one, the flipped plate body two is blocked by the beam, and the plate body two cannot fit with the upper end surface of plate body one. At this time, continue to flip the swing rod, and assist in adjusting the position of the beam until the flipped plate body two fits with the upper end surface of plate body one, so that the plate body two flips down and presses down to correct the end of the beam, thereby ensuring that the end of the beam is parallel to the support plate mechanism.

[0016] 2. In the process of driving the two sets of plate bodies one in opposite directions, the end of the beam is located on the L-shaped plate, and the end face of the beam contacts the inner side face of the L-shaped plate, and then the screw is rotated. As the screw rotates, the movable plate slides along the inner cavity of the L-shaped plate, and at the same time, the movable plate drives the two sets of pins to slide along the two sets of disguised slide grooves respectively. During the sliding of the pins along the disguised slide grooves, the pins squeeze the inner wall of the upper turning section of the disguised slide groove, so that the two sets of receiving plates move toward each other in the inner cavity of the L-shaped plate, and at the same time, the receiving plate drives the plate body one through the guide column, so that the two sets of plate bodies one also move toward each other, until the pins are offset from the upper turning section of the disguised slide groove, thereby realizing the clamping and correction of the ends of a pair of beams of the above-mentioned two sets of plate bodies.

[0017] 3. Continue to rotate the screw, the movable plate continues to slide along the inner cavity of the L-shaped plate, the movable plate squeezes the roller through the inverted slope, so that the roller slides along the inverted slope, and the roller pushes the insertion rod to slide along the rectangular hole, the insertion rod drives shaft one to slide along the rectangular slide groove, and at the same time shaft one squeezes the inner wall of the rectangular slide groove to flip the rocker arm, thereby realizing the flipping of the above-mentioned plate body 2 to press down the end of the correction beam, and secondly, the setting of the roller reduces the friction between one end of the insertion rod and the inverted slope, thereby reducing the wear between the end of the insertion rod and the inverted slope.

[0018] 4. Continue to rotate the screw rod to insert the movable sleeve together with the limit plate into the limit slot until the limit plate reaches the bottom of the limit slot and cannot move. At this time, the driving rod pushes the L-shaped rod to slide along the guide hole on the fixed plate and compresses the spring. At the same time, the end of the L-shaped rod slides along the spiral groove on the rotating tube. As the end of the L-shaped rod slides along the spiral groove, the rotating tube will rotate, and the rotating tube drives the limit plate to rotate in the limit plate. After rotation, the limit plate deviates from the original slot position of the limit slot, so that the limit plate is limited in the limit slot, thereby limiting the crossbeam on the L-shaped plate.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example 1

[0031] like Figures 1 to 5As shown, an assembled FRP bar reinforced seawater and sea sand concrete node described in an embodiment of the present invention includes a support beam 1, four groups of fixing components 2 are arranged on the upper end of the support beam 1, the fixing components 2 are used to fix the cross beam 3, and the fixing components 2 include: a support plate mechanism 201, the support plate mechanism 201 is fixedly installed on the upper end of the support beam 1, two groups of correction plate mechanisms 202 are symmetrically distributed on both sides of the support plate mechanism 201, and a triangular support frame 203 fixed on the lower end of the support plate mechanism 201, the correction plate mechanism 202 includes a plate body 1 2021, a rotation shaft 2022 is screwed on the plate body 1 2021, the rotation shaft 2022 is fixed on the swing rod 2023, the upper end of the swing rod 2023 is fixedly connected to the plate body 2 2024, the two groups of plate bodies 1 2021 are driven to clamp the cross beam 3, and the swing rod 2023 is used to drive the plate body 2 2024 to flip and press down the cross beam 3.

[0032] Specifically, when the fixing assembly 2 is not in use, the spacing between the two sets of correction plate mechanisms 202 is greater than the width of the beam 3. Therefore, when the beam 3 is installed, the end of the beam 3 is easier to be placed on the support plate mechanism 201, and the end of the beam 3 is located between the two sets of support plate mechanisms 201. Then, the two sets of plate bodies 1 2021 are driven toward each other, and the two sets of plate bodies 1 2021 move toward the two sides of the beam 3 respectively, so that the two sides of the beam 3 are squeezed by the two sets, so that the beam 3 is clamped in the middle of the support plate mechanism 201, and then the two sets of swing rods 2023 are driven at the same time, so that the swing rods 2023 are rotated with the shaft 2022 The axis is deflected, and the swing rod 2023 drives the plate body 2024 to flip toward the beam 3. At this time, if the upper end surface of the beam 3 is not flush with the upper end surface of the plate body 1 2021, the flipped plate body 2024 is blocked by the beam 3, and the plate body 2024 cannot fit with the upper end surface of the plate body 1 2021. At this time, the swing rod 2023 continues to be flipped, and the position of the beam 3 is assisted to be adjusted until the flipped plate body 2024 fits with the upper end surface of the plate body 1 2021, so that the plate body 2024 flips down and presses down to correct the end of the beam 3, thereby ensuring that the end of the beam 3 is parallel to the support plate mechanism 201.

[0033] like Figure 6 to Figure 7As shown, the support plate mechanism 201 includes: an L-shaped plate 2011, the L-shaped plate 2011 is fixedly connected to the triangular support frame 203, four groups of mounting grooves 11 are arranged at equal angles on the upper end of the support beam 1, the L-shaped plate 2011 and the triangular support frame 203 are both fixed in the mounting grooves 11, a movable plate 2012 is slidably installed in the inner cavity of the L-shaped plate 2011, a screw 2013 screwed to the movable plate 2012, the screw 2013 is screwed to the L-shaped plate 2011, and, Two groups of receiving plates 2014 are symmetrically arranged below the movable plate 2012, and a disguised slide groove 141 is provided on the receiving plate 2014. The lower end of the movable plate 2012 is connected to the pin shaft 123, and the pin shaft 123 is slidably connected to the disguised slide groove 141. Three groups of guide pillars 214 are equidistantly connected to one side of the plate body 2021, and the three groups of guide pillars 214 are fixedly connected to the receiving plate 2014. Six groups of through holes are symmetrically provided on both sides of the L-shaped plate 2011, and the through holes are slidably connected to the guide pillars 214.

[0034] Specifically, the L-shaped plate 2011 and the triangular support frame 203 are fastened in the installation groove 11 by bolts, the width of the cross beam 3 is equal to the width of the L-shaped plate 2011, and the upper end surface of the plate body 2021 is flush with the upper end surface of the L-shaped plate 2011. During the process of driving the two sets of plate bodies 2021 in the opposite direction, the end of the cross beam 3 is located on the L-shaped plate 2011, and the end surface of the cross beam 3 is against the inner side of the L-shaped plate 2011, and then the screw rod 2013 is rotated. As the screw rod 2013 rotates, the movable plate 2012 slides along the inner cavity of the L-shaped plate 2011, and the movable plate 2012 is brought into contact with the inner surface of the L-shaped plate 2011. The two groups of pins 123 are moved to slide along the two groups of disguised slide grooves 141 respectively. During the sliding process of the pins 123 along the disguised slide grooves 141, the pins 123 squeeze the inner wall of the turning section of the disguised slide grooves 141, so that the two groups of receiving plates 2014 move toward each other in the inner cavity of the L-shaped plate 2011. At the same time, the receiving plates 2014 drive the plate body 2021 through the guide pillars 214, so that the two groups of plate bodies 2021 also move toward each other until the pins 123 are offset from the turning section of the disguised slide grooves 141, thereby realizing the clamping correction of the two groups of plate bodies 2021 on the end of the beam 3.

[0035] like Figure 6 to Figure 7 As shown, the support plate mechanism 201 also includes: a receiving mechanism 2016, which is used to drive the rocker arm 2023 to flip, and the receiving mechanism 2016 includes: an insertion rod 161, a rectangular hole 211 is provided on one side of the plate body 2021, the insertion rod 161 is inserted into the rectangular hole 211, a roller 162 is screwed on one end of the insertion rod 161, and an axis 163 is fixed on the other end of the insertion rod 161, a rectangular slide groove 231 is provided on the rocker arm 2023, the rectangular slide groove 231 is slidably connected to the axis 163, two groups of avoidance grooves 121 are symmetrically provided on the movable plate 2012, an inverted inclined surface 122 is provided in the avoidance groove 121, the roller 162 is rollingly connected to the inverted inclined surface 122, an avoidance groove 212 is provided on one side of the plate body 2021, a U-shaped spring piece 213 is provided in the avoidance groove 212, and the U-shaped spring piece 213 is close to the rocker arm 2023.

[0036] Specifically, before driving the two sets of swing rods 2023, the two sets of plate bodies 1 2021 are moved toward each other by rotating the screw rod 2013. At the same time, the two sets of plate bodies 1 2021 drive the two sets of plug rods 161 to move toward each other, and one end of the plug rod 161 extends into the avoidance groove 2 121 until the two sets of plate bodies 1 2021 clamp the ends of the cross beam 3. At this time, the roller 162 at one end of the plug rod 161 is just close to the inverted inclined surface 122 in the avoidance groove 2 121. Then the screw rod 2013 is continuously rotated, and the movable plate 2012 continues to slide along the inner cavity of the L-shaped plate 2011. The movable plate 2012 passes through The inverted slope 122 squeezes the roller 162, causing the roller 162 to slide along the inverted slope 122, and the roller 162 pushes the insertion rod 161 to slide along the rectangular hole 211, and the insertion rod 161 drives the shaft 163 to slide along the rectangular slide groove 231, and at the same time, the shaft 163 squeezes the inner wall of the rectangular slide groove 231, causing the rocker rod 2023 to flip, thereby realizing the flipping of the plate body 2 2024 to press down the end of the correction beam 3, and secondly, the setting of the roller 162 reduces the friction between one end of the insertion rod 161 and the inverted slope 122, thereby reducing the wear between the end of the insertion rod 161 and the inverted slope 122. Example 2

[0037] like Figure 4 , Figure 8 , Fig. 9 As shown, compared with Example 1, another embodiment of the present invention is: the support plate mechanism 201 also includes: a limiting mechanism 2015, the limiting mechanism 2015 is used to limit the crossbeam 3, and the limiting mechanism 2015 includes: a driving rod 151, one end of the driving rod 151 is fixedly connected to the movable plate 2012, an L-shaped rod 152 fixedly connected to the other end of the driving rod 151, a fixed plate 153 plugged into the L-shaped rod 152, a spring 154 sleeved on the L-shaped rod 152, a movable sleeve 155 fixedly connected to the fixed plate 153, a screw-on tube 156 screwed into the movable sleeve 155, and a spring 154 fixed to the L-shaped rod 152. A limiting plate 157 is provided at the end of the rotating tube 156, a guide hole is provided on the fixed plate 153, the L-shaped rod 152 is slidably connected to the guide hole, a spiral groove 51 is provided on the rotating tube 156, the end of the L-shaped rod 152 is slidably connected to the spiral groove 51, two groups of arc-shaped slide grooves 111 are symmetrically provided on both sides of the L-shaped plate 2011, the movable sleeve 155 together with the limiting plate 157 are slidably connected to the arc-shaped slide groove 111, two groups of limiting slide grooves 31 are symmetrically provided on both sides of the end of the beam 3, a limiting groove 32 is provided in the limiting slide groove 31, the movable sleeve 155 together with the limiting plate 157 are inserted into the limiting slide groove 31, and the limiting plate 157 is clamped into the limiting groove 32.

[0038] Specifically, when the screw 2013 is rotated to make the movable plate 2012 slide along the inner cavity of the L-shaped plate 2011, the movable plate 2012 simultaneously drives the driving rod 151 to move, and the driving rod 151 pushes the fixed plate 153 through the elastic force of the spring 154, and the fixed plate 153 drives the movable sleeve 155 and the limit plate 157 to slide along the arc-shaped slide groove 111. When the two sets of plate bodies 1 2021 clamp and correct the end of the beam 3 and the plate body 2024 flips down and presses down the end of the beam 3, the limit plate 157 is at the intersection of the arc-shaped slide groove 111 and the limit slide groove 31, and the arc-shaped slide groove 111 is opposite to the limit slide groove 31, and the screw 2013 is continuously rotated to make the movable sleeve 155 and the limit slide groove 31 intersect. The limiting plate 157 is inserted into the limiting groove 31 until the limiting plate 157 reaches the bottom of the limiting groove 32 and cannot move. At this time, the driving rod 151 pushes the L-shaped rod 152 to slide along the guide hole on the fixing plate 153 and compresses the spring 154. At the same time, the end of the L-shaped rod 152 slides along the spiral groove 51 on the rotating tube 156. As the end of the L-shaped rod 152 slides along the spiral groove 51, the rotating tube 156 will rotate, and the rotating tube 156 drives the limiting plate 157 to rotate in the limiting plate 157. After rotation, the limiting plate 157 deviates from the original groove position of the limiting groove 31, so that the limiting plate 157 is limited in the limiting groove 32, thereby limiting the cross beam 3 on the L-shaped plate 2011.

[0039] Working principle: when installing the cross beam 3, it is easier to place the end of the cross beam 3 on the support plate mechanism 201, and the end of the cross beam 3 is located between the two groups of support plate mechanisms 201, and then the screw rod 2013 is rotated. As the screw rod 2013 rotates, the movable plate 2012 slides along the inner cavity of the L-shaped plate 2011, and at the same time, the movable plate 2012 drives the two groups of pins 123 to slide along the two groups of disguised slide grooves 141 respectively. During the sliding process of the pins 123 along the disguised slide groove 141, the pins 123 squeeze the inner wall of the turning section of the disguised slide groove 141, so that the two groups of receiving plates 2014 move toward each other in the inner cavity of the L-shaped plate 2011. At the same time, the receiving plate 2014 drives the plate body 2021 through the guide column 214, so that the two groups of plate bodies 2021 also move toward each other, and the two The plate bodies 1 2021 respectively move toward the two side surfaces of the beam 3, so that the two side surfaces of the beam 3 are squeezed by the two groups respectively, thereby clamping the beam 3 in the middle of the support plate mechanism 201, and before driving the two groups of swing rods 2023, by rotating the screw 2013, the two groups of plate bodies 1 2021 move toward each other, and at the same time, the two groups of plate bodies 1 2021 respectively drive the two groups of plug rods 161 to move toward each other, and one end of the plug rod 161 extends into the avoidance groove 2 121 until the two groups of plate bodies 1 2021 clamp the end of the beam 3, at this time, the roller 162 at one end of the plug rod 161 is just close to the inverted inclined surface 122 in the avoidance groove 2 121, and then continue to rotate the screw 2013, the movable plate 2012 continues to slide along the inner cavity of the L-shaped plate 211, and the movable plate 2012 passes through the inverted inclined surface 122 squeezes roller 162, so that roller 162 slides along inverted slope 122, and roller 162 pushes insertion rod 161 to slide along rectangular hole 211, insertion rod 161 drives shaft 163 to slide along rectangular slide groove 231, and shaft 163 squeezes the inner wall of rectangular slide groove 231, so that swing rod 2023 flips, so that plate body 2 2024 flips down and presses down the end of correction beam 3, and screw rod 2013 is rotated to make movable plate 2012 slide along the inner cavity of L-shaped plate 2011, and movable plate 2012 drives driving rod 151 to move at the same time, and driving rod 151 pushes fixed plate 153 through the elastic force of spring 154, and fixed plate 153 drives movable sleeve 155 together with limiting plate 157 to slide along arc slide groove 111, and when two sides are realized, After the plate body 1 2021 clamps and corrects the end of the beam 3 and the plate body 2024 flips down and presses down to correct the end of the beam 3, the limit plate 157 is at the intersection of the arc-shaped slide groove 111 and the limit slide groove 31, and the arc-shaped slide groove 111 is opposite to the limit slide groove 31. The screw rod 2013 continues to be rotated to insert the movable sleeve 155 together with the limit plate 157 into the limit slide groove 31 until the limit plate 157 reaches the bottom of the limit groove 32 and cannot move. At this time, the driving rod 151 pushes the L-shaped rod 152 to slide along the guide hole on the fixed plate 153 and compresses the spring 154. At the same time, the end of the L-shaped rod 152 slides along the spiral groove 51 on the rotary tube 156. As the end of the L-shaped rod 152 slides along the spiral groove 51, the rotary tube 156 will rotate.The rotating tube 156 drives the limiting plate 157 to rotate in the limiting plate 157 , and the rotating limiting plate 157 deviates from the original slot position of the limiting slide slot 31 , so that the limiting plate 157 is limited in the limiting slot 32 .
