Description

Technical Field

[0001] The present invention relates to the technical field of steel column construction, in particular to a super high-rise building steel column embedded column foot construction device and a construction process thereof. Background Art

[0002] A steel column is a columnar structure made of steel, commonly used in buildings, bridges, towers and other projects to provide support and load-bearing. The embedded column base of a steel column refers to a connection method in which the bottom of the steel column is embedded in the concrete foundation. This design method can provide better stability and load-bearing capacity, while also enhancing the integrity between the steel column and the foundation.

[0003] Since the bottom of the steel column needs to be embedded in the concrete to improve the stability and integrity between the steel column and the foundation, when the position of the steel column deviates, the steel column cannot be adjusted because the position of the base plate is fixed, and the position of the base plate needs to be re-determined, which is time-consuming and labor-intensive. In addition, when the steel column is being constructed and concrete is poured, the continuous pouring of concrete will cause impact on the steel column, and in severe cases, the steel column will tilt, affecting the construction progress of the steel column.

[0014] A construction process for a super high-rise building steel column embedded column foot construction device, the process steps are as follows: S1: The active component is pushed upward inside the foundation by the gravity of the steel column and the base plate, thereby limiting and fixing the steel column and the base plate by controlling the two sets of clamping blocks, thereby improving the stability of the steel column during pouring; S2: By rotating the screw rod, the threaded sleeve is driven to rotate inside the adjustment block. The adjustment block is controlled to move above the base plate by the size of the two sets of thread pitches to determine the position of the steel column during construction. S3: The piston rod is pushed to move by the swing of the receiving plate, and the defoaming agent is evenly added to the concrete being poured. At the same time, the swing amplitude of the arc rod is adjusted by adjusting the rotation of the screw rod to further eliminate bubbles in the concrete; S4: The up and down movement of the pressing plate drives the exhaust rod to deal with the bubbles inside the concrete being poured. At the same time, the movement of the pressing plate compacts the concrete and can also tightly limit the side of the steel column; S5: The continuous up and down movement of the exhaust rod not only improves the efficiency of dealing with bubbles in the concrete being poured, but also effectively reduces the stress on the two sets of clamping blocks during operation, and improves the stability of the fixing assembly in fixing the steel column and the base plate; S6: The push plate driven by the pressing plate moves up and down, and the blocking plate at one end of the top column is pushed by the push plate to swing under the casting plate, which can cooperate with the exhaust rod to move up and down inside the concrete, thereby improving the efficiency of the exhaust rod in adsorbing bubbles and improving the overall casting quality of the steel column.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can push the active part downward through the gravity of the steel column and the base plate. When the active part moves, it will drive the two sets of clamping blocks to move in the internal cavity of the base plate through the pin shaft, clamp and fix the base plate, and improve the stability of the steel column during pouring. At the same time, when the rotating screw drives the threaded sleeve to rotate inside the adjusting block, it can pull the steel column above the adjusting block to adjust the position, thereby improving the accuracy of the position of the steel column during construction. In the adjustment process, the adjusting block will drive the wedge block to squeeze the cylindrical head, thereby applying a reverse extrusion force to the active part, thereby improving the effect of the clamping block on clamping and limiting the base plate.

[0016] 2. The present invention causes concrete to fall into the receiving bin at one end of the receiving plate, thereby driving the receiving plate to swing. The swing of the receiving plate drives the knocking ball at one end of the arc rod to knock on the casting plate, thereby processing the bubbles generated by the concrete being poured and preventing the concrete from being blocked during the pouring process, with high work efficiency. At the same time, by adjusting the rotation of the screw rod inside the receiving plate, the swing amplitude of the arc rod can be changed, and the force of the knocking ball on the casting plate can be increased, which is more efficient.

[0017] 3. The present invention pushes the sliding column to move up and down through the swing of the material receiving plate, and the movement of the sliding column drives the pressing plate to move up and down. The movement of the pressing plate pushes the exhaust rod to move in the concrete through the matching column under the sliding rod, which can further deal with the bubbles generated inside it. At the same time, one side of the pressing plate moves up and down on one side of the steel column, which can improve the stability of the steel column when the concrete is poured, reduce the impact force of the concrete on it, and has high safety.

[0018] 4. The present invention drives the push plate to move up and down through the pressing plate. When the push plate moves, it pushes the blocking plate at one end of the top column to swing through the inclined surface. The swing of the blocking plate will block the concrete through the inclined plate, reduce the amount of concrete falling, facilitate the downward movement of the exhaust rod to deal with bubbles, and can reduce the stress on the clamping block after the concrete falls, protect it, and extend its service life.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 10 The present invention provides a technical solution: a construction device for embedded column bases of steel columns in super high-rise buildings, comprising a foundation 1, a steel column 2, a stiffener 3, a bottom plate 4 and an anchor bolt 6. The steel column 2 is located below the stiffener 3 and is fixedly connected to a casting plate 7. A blocking plate 5 is rotatably connected to the bottom of the casting plate 7 via a pin. A top column 8 is fixed to the side of the blocking plate 5. A cavity is provided inside the bottom plate 4, and a fixing component 100 for fixing and clamping the steel column 2 is provided below the bottom plate 4. An auxiliary component 200 for eliminating bubbles in concrete is provided on the side of the steel column 2. A gain component 300 for improving the casting quality of the steel column 2 is provided inside the foundation 1. Among them, by the movement of the two groups of clamping blocks 103 in the fixing assembly 100 in the cavity inside the base plate 4, the base plate 4 is quickly and stably installed inside the foundation 1, thereby improving the stability of the steel column 2 installed above the base plate 4 inside the foundation 1, avoiding the tilting phenomenon under the influence of pouring or other external environment, and improving the stability of the pouring of the steel column 2.

[0023] The fixing assembly 100 includes an active member 101, which slides in the cavity of the bottom plate 4. A movable plate 102 is fixed to the surface of the active member 101. The two ends of the movable plate 102 are rotatably connected to a clamping block 103 via a pin. The clamping block 103 has a folding groove formed inside, and a limiting column 106 is provided inside the folding groove. The limiting column 106 is fixed to the base 1 through a fixing frame 104. Among them, the fixed fixing frame 104 can stably install the fixing component 100 inside the foundation 1, so as to better limit and fix the steel column 2 and the base plate 4, and the setting of the folding groove enables the two sets of clamping blocks 103 to move quickly in the cavity inside the base plate 4, thereby locking it and having high stability.

[0024] The auxiliary component 200 includes a receiving plate 201, one end of which is provided with a receiving bin, an internal rotationally connected mounting screw 207 of the receiving plate 201, the mounting screw 207 being threadedly connected to the steel column 2, an internal threaded connection of the receiving plate 201 with an adjusting screw 202, one end of which is rotatably connected to an arc rod 203; Among them, by opening a material receiving bin at one end of the material receiving plate 201, the impact generated during concrete pouring will drive the material receiving plate 201 to swing, thereby being able to process a large number of bubbles generated during concrete pouring. The material receiving bin at one end of the material receiving plate 201 can reduce the impact force on the surface of the steel column 2 during concrete pouring, and can avoid the steel column 2 from tilting due to a large impact force.

[0025] The gain component 300 includes a sliding column 301, which is located directly below the material receiving plate 201. A pressing plate 303 is fixedly connected below the sliding column 301, and a sliding rod 306 is fixedly connected below the pressing plate 303.

A push plate 309 is fixedly connected to the side of the pressing plate 303, and a slope is provided on one side of the push plate 309 for use with the top column 8.

[0026] The movement of the pressing plate 303 not only compacts the concrete, but also further improves the stability of the steel column 2 during pouring because one side of the pressing plate 303 slides on the side of the steel column 2 .

[0027] Furthermore, a cylindrical head 105 is fixed to the upper end of the active part 101, and two groups of wedge blocks 110 are arranged above the cylindrical head 105. The wedge blocks 110 are slidably connected to the base plate 4. An adjustment block 109 is fixed above the wedge block 110. One end of the adjustment block 109 is threadedly connected to a threaded sleeve 108. A rotating screw 107 is fixed to the inside of the threaded sleeve 108. The rotating screw 107 is threadedly connected to the base plate 4. The pitch of the thread of the threaded sleeve 108 is greater than the pitch of the thread on the surface of the rotating screw 107.

[0028] Among them, by providing a cylindrical head 105 and two groups of symmetrically arranged wedge blocks 110 at the upper end of the active part 101, when the rotating screw 107 drives the adjustment block 109 through the threaded sleeve 108 to adjust the position of the upper steel column 2, the movement of the two groups of wedge blocks 110 can also apply an extrusion force to the active part 101, thereby improving the stability of the two groups of clamping blocks 103 in limiting and fixing the base plate 4 and the steel column 2.

[0029] Furthermore, one end of the arc rod 203 is detachably connected to a knocking ball 204, and the arc rod 203 is slidingly connected to the receiving plate 201. A piston rod 205 is provided above the receiving plate 201, and the surface of the piston rod 205 is slidingly connected to the piston cylinder 206. The surface of the piston cylinder 206 is fixedly connected to an external pipe 209, and the end of the external pipe 209 away from the piston cylinder 206 is connected to a liquid storage tank for storing the defoaming agent. A connecting pipe 208 is also fixedly connected to the bottom of the piston cylinder 206, and the end of the connecting pipe 208 away from the piston cylinder 206 is connected to the inside of the receiving bin at one end of the receiving plate 201.

[0030] Among them, the knocking ball 204 is set to knock on the surface of the casting plate 7. On the one hand, it can vibrate the falling concrete and eliminate the bubbles generated inside the concrete. On the other hand, it can prevent the concrete from being blocked and improve the pouring efficiency. Moreover, through the continuous movement of the piston rod 205, the defoaming agent can be evenly sprayed into the descending concrete through the receiving bin at one end of the receiving plate 201, further improving the effect of eliminating bubbles.

[0031] Furthermore, the surface of the sliding column 301 is slidably connected to the support plate 302, and the side of the support plate 302 is fixed with an L-shaped rod 305. The L-shaped rod 305 is provided with several groups of protrusions on the side close to the sliding rod 306. The surface of the matching column 307 is slidably connected to the exhaust rod 304. A through hole is provided above the exhaust rod 304, and a slide is provided at the position of the through hole. The surface of the exhaust rod 304 also has several groups of small air suction holes. The exhaust rod 304 is made of a material with light weight and high surface smoothness.

[0032] Among them, the provision of the exhaust rod 304 can not only discharge the bubbles inside the concrete, but also reduce the stress generated by the concrete during pouring, thereby providing protection for the clamping block 103 and further improving the stability of the steel column 2 during pouring.

[0033] Furthermore, an elastic telescopic rod 308 is fixed to the surface of the sliding rod 306, a reset element is provided at the connection position between the sliding column 301 and the support plate 302, the support plate 302 and the foundation 1 are detachably installed, one side of the pressing plate 303 slides on the side of the steel column 2, and four groups of triangular ribs are distributed at the four corners of the bottom of the steel column 2. One end of the pressing plate 303 fits tightly with the inclined side surface inside the foundation 1.

[0034] When the steel column 2 is adjusted in position by the movement of the adjustment block 109 , the triangular ribs will move along with the steel column 2 , providing stability to the steel column 2 during movement and preventing the steel column 2 from being affected by excessive movement.

[0035] Furthermore, a slot is provided at the bottom of the steel column 2, which is tightly engaged with the adjustment block 109. Threaded holes are provided on the front and rear sides of the base plate 4. Anchor bolts 6 are distributed at the four corners of the bottom of the base plate 4. The bottom end of the anchor bolt 6 is set to be conical. The fixing component 100 and the base plate 4 are both made of materials with high strength and high corrosion resistance.

[0036] Among them, the slot opened at the bottom of the steel column 2 makes the steel column 2 fit tightly with the adjustment block 109 above the base plate 4. At the same time, the bottom of the anchor bolt 6 is set to a cone shape to improve the connection strength with the foundation 1 and improve the stability of the base plate 4 inside the foundation 1.

[0037] Furthermore, an inclined plate is fixedly provided at the bottom of the blocking plate 5, a through groove is opened inside the casting plate 7, the receiving plate 201 is provided with a receiving bin, one end of which swings up and down inside the through groove, one end of the piston cylinder 206 is located on one side of the rib plate 3, and a one-way valve is provided inside the connecting pipe 208 and the external pipe 209.

[0038] Among them, by setting an inclined plate at the bottom of the blocking plate 5, when the push plate 309 pushes the blocking plate 5 at one end of the top column 8 to swing, the amount of concrete falling from the pouring port can be reduced, thereby improving the efficiency of the exhaust rod 304 in discharging bubbles inside the concrete, and also avoiding the phenomenon of excessive stress caused by rapid pouring of concrete.

[0039] Furthermore, the L-shaped rod 305 and the protrusions on its surface slide in the slide groove opened on the surface of the pressing plate 303. A trapezoidal cavity is opened inside the foundation 1, and a pouring port is opened inside the rib plate 3 above the pouring plate 7. The weight of the arc rod 203 and the knocking ball 204 is greater than the weight of the material bin at one end of the receiving plate 201.

[0040] Among them, through the arrangement of the protrusion and the elastic telescopic rod 308, the exhaust rod 304 can vibrate when it moves up and down, thereby improving the efficiency of removing bubbles and also improving the efficiency of pulling the exhaust rod 304 out of the concrete.

[0041] Furthermore, the present invention also provides a construction process for a super high-rise building steel column embedded column foot construction device, the process steps of which are as follows: S1: The active member 101 is pushed upward inside the foundation 1 by the gravity of the steel column 2 and the bottom plate 4, thereby limiting and fixing the steel column 2 and the bottom plate 4 by controlling the two sets of clamping blocks 103, thereby improving the stability of the steel column 2 during pouring; S2: By rotating the screw 107, the threaded sleeve 108 rotates inside the adjustment block 109. The adjustment block 109 is controlled to move above the base plate 4 by the size of the two sets of thread pitches to determine the position of the steel column 2 during construction; S3: The piston rod 205 is pushed to move by the swing of the receiving plate 201 to evenly add the defoaming agent to the concrete being poured. At the same time, the swing amplitude of the arc rod 203 is adjusted by adjusting the rotation of the screw rod 202 to further eliminate bubbles in the concrete. S4: The pressing plate 303 moves up and down to drive the exhaust rod 304 to deal with bubbles in the concrete being poured. At the same time, the pressing plate 303 moves to compact the concrete and tightly limit the side of the steel column 2; S5: The continuous up and down movement of the exhaust rod 304 not only improves the efficiency of treating bubbles in the concrete being poured, but also effectively reduces the stress on the two sets of clamping blocks 103 during operation, thereby improving the stability of the fixing assembly 100 in fixing and limiting the steel column 2 and the base plate 4; S6: The push plate 309 driven by the pressing plate 303 moves up and down, and the blocking plate 5 at one end of the top column 8 is pushed by the push plate 309 to swing under the casting plate 7, which can cooperate with the exhaust rod 304 to move up and down inside the concrete, thereby improving the efficiency of the exhaust rod 304 in adsorbing bubbles, and also improving the overall casting quality of the steel column 2.

[0042] Working principle: Before pouring concrete on the steel column 2, multiple steel bars are laid inside the foundation 1, and a mounting hole is opened at the bottom of the foundation 1. The fixing assembly 100 is installed inside the foundation 1, and the bottom plate 4 is installed above the fixing assembly 100. The two sets of clamping blocks 103 in the fixing assembly 100 are inserted into the bottom plate 4 from an inclined state, and the bottom plate 4 is fixed to the inside of the foundation 1 by two sets of bolts and steel bars; when the bottom plate 4 is installed above the fixing assembly 100, due to gravity, the bottom plate 4 will push the cylindrical head 105 and the active member below 101 moves downward inside the foundation 1, and the active part 101 moves downward to drive the clamping block 103 to move downward through the pin shaft. When the clamping block 103 moves downward, it will slide on the surface of the limit column 106 through the internal folding groove, causing the clamping block 103 to swing so that its upper end can be inserted into the cavity of the base plate 4. However, due to insufficient gravity of the base plate 4, the end face of the clamping block 103 cannot be completely in contact with the cavity of the base plate 4, which makes it convenient for construction personnel to adjust the position of the base plate 4 inside the foundation 1 and improves the accuracy of the steel column 2 during construction.

[0043] When the bottom plate 4 is installed, the steel column 2 is installed above the bottom plate 4. Since the bottom of the steel column 2 is provided with a slot, it can fit with the adjusting block 109 to improve the accuracy of the installation position of the steel column 2; when it is necessary to adjust the installation position of the steel column 2 left and right, the construction personnel rotate the rotating screw 107 to drive the threaded sleeve 108 to rotate. The threaded sleeve 108 is threadedly connected to the adjusting block 109, and the pitch of the thread on the surface of the rotating screw 107 is smaller than the pitch of the thread on the surface of the threaded sleeve 108. Therefore, when the rotating screw 107 drives the threaded sleeve 108 to rotate, the adjusting block 109 can be pulled to move above the bottom plate 4. The moving distance is determined by setting the length of the threaded sleeve 108. At the same time, the movement of the adjusting block 109 can drive the steel column 2 clamped therewith to move left and right on the surface of the bottom plate 4, adjust its position, and at the same time make the steel column 2 stably connected to the bottom plate 4 below the adjusting block 109.

[0044] Since there are multiple sets of triangular ribs on the side of the steel column 2, the stability of the steel column 2 when it moves above the base plate 4 can be improved, and the steel column 2 can be prevented from tilting or moving inaccurately during the movement. When the card slot set below the steel column 2 is engaged with the adjustment block 109, the gravity of the steel column 2 can further apply pressure to the base plate 4. At this time, the base plate 4 will completely push the active member 101 downward to make the two sets of card blocks 103 completely engaged with the base plate 4, thereby improving the stability of the base plate 4 installed inside the foundation 1, thereby improving the stability of the installation of the steel column 2; since the steel column 2 is installed After being installed on the top of the base plate 4, its position is adjusted. When the rotating screw 107 rotates through the threaded sleeve 108, it can drive the adjustment block 109 to move. The adjustment block 109 moves through the inclined surfaces of the two sets of wedge blocks 110 to contact the cylindrical head 105, so that the active part 101 under the cylindrical head 105 is in closer contact with the foundation 1, further improving the contact force between the two sets of clamping blocks 103 and the base plate 4, and having high stability; when the position of the steel column 2 is determined, the staff will fix the steel column 2 to the base plate 4 by welding or other means to facilitate the subsequent concrete pouring.

[0045] When it is necessary to cast and fix the column foot of the steel column 2, first install the auxiliary component 200 on the side of the steel column 2 by installing the screw rod 207, and install the gain component 300 to a position horizontal to the foundation 1 through the sliding column 301. Since a pouring port is opened inside the rib plate 3, the bottom of the pouring port is connected to the inside of the pouring plate 7, which makes it convenient for workers to pour concrete into the inside of the foundation 1. The blocking plate 5 and the pouring plate 7 can prevent the concrete from splashing during the pouring process. At the same time, the external pipe 209 is connected to the inside of the external liquid storage tank where the defoaming agent is stored. When concrete pouring starts, since the receiving plate 201 is initially in an inclined state, the concrete falls into the receiving bin at one end of the receiving plate 201 through the pouring port. When the weight of the concrete collected by the receiving plate 201 is greater than the weight of the arc rod 203 and the knocking ball 204 below, the receiving plate 201 swings around the mounting screw 207. When the receiving plate 201 swings upward, it can push the piston rod 205 to slide inside the piston cylinder 206, and the defoaming agent inside the liquid storage tank is pumped into the interior of the piston cylinder 206 through the external pipe 209, and then transported to the inside of the receiving bin at one end of the receiving plate 201 through the connecting pipe 208 connected to the bottom of the piston cylinder 206, and sprayed into the concrete being poured through the receiving plate 201, so that the defoaming agent is evenly added to the concrete, reducing the bubbles generated during concrete pouring and improving the quality of concrete pouring.

[0046] The arc rod 203 is driven away from the steel column 2 by adjusting the screw rod 202, thereby increasing the swing amplitude of the arc rod 203 and increasing the force of the knocking ball 204 on the casting plate 7. The casting plate 7 can be knocked continuously with different forces, thereby avoiding a large number of bubbles in the concrete after pouring.

[0047] When the sliding rod 306 drives the matching column 307 to move upward, the matching column 307 is located above the exhaust hole, and the air sucked in the exhaust rod 304 is discharged to the outside, which can further deal with the bubbles generated during the concrete pouring process.

[0048] Since the exhaust rod 304 continuously moves up and down inside the concrete until the concrete is poured to be level with the foundation 1, the adhesion and pressure of the concrete reduce the speed of the exhaust rod 304 moving up and down. When the matching column 307 inside the exhaust rod 304 is located below the exhaust pipe, the pressure inside the exhaust rod 304 will be the same as the pressure inside the concrete. Moreover, since the exhaust rod 304 is made of a light material with a smooth surface, the exhaust rod 304 can better move up and down inside the concrete.

[0049] As the pressing plate 303 continuously moves up and down, when the pressing plate 303 moves, it will drive the push plate 309 to move. When the push plate 309 moves downward, the exhaust rod 304 will also move downward. When the push plate 309 moves downward, it will push the blocking plate 5 at one end of the top column 8 to move around the pin axis toward the side close to the steel column 2 through the inclined surface. Since an inclined plate is provided at the bottom of the blocking plate 5, the position of the inclined plate at this time can block the falling concrete, reduce the falling of concrete, and facilitate the exhaust rod 304 to be inserted into the concrete that has been poured below, further improving the treatment of bubbles inside the concrete.

[0050] The support plate 302 is detachably mounted on the foundation 1. When the sliding rod 306 moves downward, it drives the elastic telescopic rod 308 to move downward. The downward movement of the elastic telescopic rod 308 will contact the protrusion on the L-shaped rod 305, so that the exhaust rod 304 as a whole will vibrate slightly when moving up and down, which not only improves the effect of treating bubbles inside the concrete, but also reduces the resistance of the exhaust rod 304 to the up and down movement inside the concrete. Moreover, since one side of the pressing plate 303 will contact the side of the steel column 2 when moving up and down, it can not only compact the concrete that is about to be filled, but also limit the side of the steel column 2 being poured, thereby avoiding the steel column 2 from tilting during the pouring process, reducing the stress generated when the two sets of clamping blocks 103 clamp the bottom plate 4, and improving the stability of the steel column 2 during pouring.

[0051] When the concrete is poured to the same level as the top of the foundation 1, a pouring box is installed around the steel column 2. At the same time, the auxiliary component 200 and the gain component 300 are taken out from the inside of the foundation 1, and the exposed part of the steel column 2 is poured, thereby completing the construction work of the steel column 2.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to the embodiments without departing from the spirit and scope of the invention, the scope of which is defined by the claims and their equivalents.
