Working principle:
Before concrete is poured on the steel column 2, a plurality of steel bars are paved in the foundation 1, a mounting hole is formed in the bottom of the foundation 1, the fixing assembly 100 is mounted in the foundation 1, the bottom plate 4 is mounted above the fixing assembly 100, two groups of clamping blocks 103 in the fixing assembly 100 are inserted into the bottom plate 4 from an inclined state, the bottom plate 4 is fixed in the foundation 1 through the two groups of bolts and the steel bars, when the bottom plate 4 is mounted above the fixing assembly 100, due to gravity, the bottom plate 4 can push the cylindrical head 105 and the driving piece 101 below downwards move in the foundation 1, the driving piece 101 downwards moves to drive the clamping blocks 103 to downwards move through the pin shafts, and when the clamping blocks 103 downwards move, the clamping blocks 103 slide on the surface of the limiting columns 106 through the inner folding grooves, so that the clamping blocks 103 swing, the upper ends of the clamping blocks can be inserted into cavities of the bottom plate 4, but due to insufficient gravity of the bottom plate 4, the end faces of the clamping blocks 103 cannot be completely contacted with the cavities of the bottom plate 4, and thus convenience is brought to convenience for constructors to adjust the position of the bottom plate 4 in the foundation 1, and accuracy of the steel column 2 is improved when construction is performed.
When the position of the steel column 2 is required to be adjusted left and right, a constructor rotates the rotating screw rod 107 to drive the threaded sleeve 108 to rotate, the threaded sleeve 108 is in threaded connection with the adjusting block 109, and the thread pitch of the surface thread of the rotating screw rod 107 is smaller than that of the threaded sleeve 108, so that when the rotating screw rod 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 the length of the threaded sleeve 108, and meanwhile, the adjusting block 109 can move to drive the steel column 2 clamped with the adjusting block to move left and right on the surface of the bottom plate 4, so that the position of the steel column 2 is adjusted, and meanwhile, the steel column 2 is stably connected with the bottom plate 4 below the adjusting block 109.
The side of the steel column 2 is provided with a plurality of groups of triangular ribbed plates, so that the stability of the steel column 2 when moving above the base plate 4 can be improved, the phenomenon that the steel column 2 inclines or the moving position is inaccurate in the moving process is avoided, after the clamping grooves arranged below the steel column 2 are clamped with the adjusting blocks 109, the gravity of the steel column 2 can further apply pressure to the base plate 4, at the moment, the base plate 4 can completely push the driving piece 101 to move downwards, two groups of clamping blocks 103 are completely clamped with the base plate 4, the stability of the base plate 4 installed inside the foundation 1 is improved, the stability of the steel column 2 installed is improved, the position of the steel column 2 is adjusted after the steel column 2 is installed above the base plate 4, the adjusting blocks 109 can be driven to move when the rotating screw rods 107 rotate through the threaded sleeves 108, the adjusting blocks 109 move to be contacted with the cylindrical heads 105 through the inclined surfaces of the two groups of the wedge blocks 110, the driving piece 101 below the cylindrical heads 105 are further improved in contact with the base plate 1, the contact force between the two groups of clamping blocks 103 and the base plate 4 is further improved, the stability is high, after the position of the steel column 2 is determined, the steel column 2 and the base plate 4 are welded with the concrete in a mode, and concrete is convenient to be fixedly connected.
When the column feet of the steel column 2 are required to be poured and fixed, the auxiliary assembly 200 is firstly installed on the side face of the steel column 2 through the installation screw rod 207, the gain assembly 300 is installed on the position which is horizontal to the foundation 1 through the sliding column 301, as the pouring opening is formed in the rib plate 3, the lower part of the pouring opening is communicated with the inside of the pouring plate 7, so that a worker can conveniently pour concrete into the foundation 1, and the blocking plate 5 and the pouring plate 7 can prevent the splashing phenomenon of the concrete in the pouring process, and meanwhile, the outer connecting pipe 209 is connected with the inside of a liquid storage tank with an antifoaming agent stored outside;
When the concrete starts pouring, as the material receiving plate 201 is in an inclined state initially, the concrete falls into the material receiving bin at one end of the material receiving plate 201 through the pouring opening, when the weight of the concrete collected by the material receiving plate 201 is larger than that of the lower Fang Yuanhu rod 203 and the knocking ball 204, the material receiving plate 201 swings around the installation screw rod 207, when the material receiving plate 201 swings upwards, the piston rod 205 can be pushed to slide in the piston cylinder 206, the defoaming agent in the liquid storage tank is pumped into the piston cylinder 206 through the outer connecting pipe 209, and then is conveyed into the material receiving bin at one end of the material receiving plate 201 through the communicating pipe 208 communicated below the piston cylinder 206, and the defoaming agent is uniformly added into the concrete by spraying the material receiving plate 201, so that the air bubbles generated during pouring of the concrete are reduced, and the pouring quality of the concrete is improved.
Before the concrete is poured, the adjusting screw rod 202 is rotated to drive the arc rod 203 to move below the receiving plate 201, the receiving plate 201 is moved to drive the striking ball 204 to move, the distance that the arc rod 203 is close to the steel column 2 is adjusted, when the arc rod 203 is close to the steel column 2, the receiving plate 201 swings to drive the striking ball 204 to strike the surface of the pouring plate 7 through the arc rod 203, air bubbles generated in the concrete pouring process can be reduced, when the concrete is continuously poured into a trapezoid cavity in the foundation 1, the concrete is continuously lifted, the striking force of the striking ball 204 is reduced, the arc rod 203 is driven to be far away from the steel column 2 through the adjusting screw rod 202, the swing amplitude of the arc rod 203 is increased, the striking force of the striking ball 204 on the pouring plate 7 is improved, the pouring plate 7 can be continuously struck through different forces, and a large number of air bubbles can be prevented from occurring in the concrete after the pouring.
When concrete is poured, the material receiving plate 201 can intermittently push the sliding column 301 to move up and down in the support plate 302 during swinging, the sliding column 301 moves to push the sliding rod 306 to move up and down through the pressing plate 303, the sliding rod 306 moves downwards to push the exhaust rod 304 to move up and down in the foundation 1 through the matching column 307, the sliding rod 304 is internally provided with a slideway, and the exhaust hole is arranged at the position of the slideway, after the sliding rod 306 moves downwards to a certain position, the exhaust rod 304 can be continuously pushed to move downwards, when the exhaust rod 304 moves downwards, the matching column 307 is arranged below the exhaust hole, so that the exhaust rod 304 forms a negative pressure state, air generated in the concrete is sucked into the interior through a tiny suction hole on the surface of the exhaust rod 304, when the sliding rod 306 drives the matching column 307 to move upwards, the matching column 307 is arranged above the exhaust hole, the air sucked in the exhaust rod 304 is discharged to the outside, and bubbles generated in the concrete pouring process can be further processed.
Because the exhaust rod 304 continuously moves up and down in the concrete until the concrete is poured to be in a horizontal state with the foundation 1, the up and down movement speed of the exhaust rod 304 is reduced due to the adhesion and pressure intensity of the concrete, when the matched column 307 in the exhaust rod 304 is positioned below the exhaust pipe, the pressure intensity in the exhaust rod 304 is the same as the pressure intensity in the concrete, and because the exhaust rod 304 is made of a material with light weight and high surface smoothness, the up and down movement of the exhaust rod 304 in the concrete can be better improved.
Because the pressing plate 303 moves up and down continuously, when the pressing plate 303 moves, the pushing plate 309 is driven to move, when the pushing plate 309 moves downwards, the exhaust rod 304 also moves downwards, when the pushing plate 309 moves downwards, the blocking plate 5 at one end of the top column 8 is pushed by the inclined plane to move around the pin shaft to one side close to the steel column 2, and because the bottom of the blocking plate 5 is provided with the inclined plate, the position of the inclined plate can block falling concrete at the moment, so that the falling of the concrete is reduced, the exhaust rod 304 is conveniently inserted into the concrete filled below, and the treatment of air bubbles in the concrete is further improved.
The backup pad 302 and basis 1 demountable installation, drive elastic telescopic link 308 downward movement when slide bar 306 downward movement, elastic telescopic link 308 downward movement can with the lug contact on the L shape pole 305, thereby make the whole light vibration that takes place when up-and-down motion of exhaust bar 304, can not only improve the effect of handling the inside bubble of concrete, can also reduce the resistance that exhaust bar 304 moved up-and-down in the concrete, and because one side of push down plate 303 can be contacted with the side of steel column 2 when up-and-down movement, not only can compact the concrete that is about to be full, can also limit the steel column 2 side that is being pour, avoid steel column 2 to appear the phenomenon of slope in the pouring process, reduce the stress that two sets of joint pieces 103 produced when fixed to bottom plate 4 chucking, stability when improving steel column 2 and pouring.
When the concrete is poured to be horizontally consistent with the upper part of the foundation 1, a pouring box is arranged around the steel column 2, and meanwhile, the auxiliary assembly 200 and the gain assembly 300 are taken out from the foundation 1, and the part of the steel column 2 exposed outside is poured, so that the construction work of the steel column 2 is completed.
