[0029] The present invention will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present invention, and the present invention is not limited to the following embodiments.

[0030] 1. The fixing unit 1 of the embodiment of the present invention includes a mounting base 11, a first fixing plate 12, a second fixing plate 13, a third fixing plate 14, a first screw mechanism 121, a second screw mechanism 131, a third screw mechanism 141, a first dial 122, a second dial 132, a third dial 142, a telescopic plate 143, a bolt 152, a clutch structure, a locking structure, a first sealing plate 124, a first trigger plate 123, a first spring 125, a second trigger plate 133, a second sealing plate 134, and a second spring 135

[0031] The first screw mechanism 121 is spirally connected to the first fixing plate 12. Both the first fixing plate 12 and the first screw mechanism 121 are vertically arranged, and the first screw mechanism 121 is installed on the mounting base 11. A first dial 122 is fixedly connected to the first screw mechanism 121. The second screw mechanism 131 is spirally connected to the second fixing plate 13. Both the second fixing plate 13 and the second screw mechanism 131 are horizontally arranged, and the second screw mechanism 131 is installed on the mounting base 11. A second dial 132 is fixedly connected to the second screw mechanism 131; the first dial 122 and the second dial 132 are meshed and connected, and both the first dial 122 and the second dial 132 are inside the mounting base 11. A telescopic plate 143 is slidably arranged on the mounting base 11, and the telescopic plate 143 is parallel to the second fixing plate 13; the third fixing plate 14 is hingedly installed on the telescopic plate 143. The third screw mechanism 141 is spirally connected to the third fixing plate 14. A third dial 142 is connected to the third screw mechanism 141, and the third dial 142 is meshed and connected with the second dial 132. In the non-use state, that is, the initial state, the third fixing plate 14 is parallel to the second fixing plate 13, and the fixing unit 1 is in an L shape. At this time, the fixing unit 1 can be sent into the internal of the ground beam steel cage; in the use state, after the third fixing plate 14 is erected, it is parallel to the first fixing plate 12, and the fixing unit 1 is in an F shape, which can fix the outer steel bars and the corresponding inner steel bars of the load-bearing beam. The bent part of the outer steel bars of the load-bearing beam is relatively long and is inserted into the internal of the ground beam steel cage under the guidance of the second fixing plate 13

[0032] The third screw mechanism 141 and the third dial 142 are connected by a clutch structure, which includes an insertion block 146 and a pin rod 147. The insertion block 146 is fixedly or slidably arranged on the third screw mechanism 141. A groove for receiving the insertion block 146 is formed on the third dial 142, and the insertion block 146 is inserted into the groove; the pin rod 147 is inserted into the third dial 142 and the insertion block 146 to fix the third dial 142 and the insertion block 146 together; the third screw mechanism 141 and the third dial 142 are fixedly connected by the insertion block 146 and the pin rod 147. When the third fixing plate 14 stops moving, the pin rod 147 is pulled out. If it is slidably arranged, at this time, the insertion block 146 can be pushed inward to retract it into the third screw mechanism 141. If it is fixedly arranged, the insertion block 146 is pushed outward to disengage the insertion block 146 from the groove. At this time, the third screw mechanism 141 is separated from the third dial 142. At this time, the third fixing plate 14 can be rotated so that the included angle between the third fixing plate 14 and the telescopic plate 143 is a right angle, and the third fixing plate 14 stands up. The third fixing plate 14 can abut against the inner wall of the stirrup to fix the steel bars inside the bearing beam.

[0033] A locking structure is arranged on the telescopic plate 143 to fix the telescopic plate 143 and prevent the telescopic plate 143 from stretching or shortening randomly. The locking structure includes a pushing block 144 and a locking rod 145. The locking rod 145 is movably arranged on the telescopic plate 143. Mortise holes adapted to the locking rod 145 and distributed in a linear array are formed on the second fixing plate 13; a pushing block 144 for pushing the locking rod 145 is fixedly arranged on the third fixing plate 14, and a slope is arranged on the pushing block 144, and the slope is connected to the locking rod 145. When the third fixing plate 14 is rotated upward, the pushing block 144 on the third fixing plate 14 rotates, and the slope on the pushing block 144 gradually pushes the locking rod 145 outward, so that the locking rod 145 extends to the outside of the telescopic plate 143 and is inserted into the mortise hole on the second fixing plate 13 to fix the telescopic plate 143 and prevent the telescopic plate 143 from stretching or shortening randomly.

[0034] The first fixing plate 12, the second fixing plate 13, the third fixing plate 14 and the telescopic plate 143 are all bent to form a fixing groove 151. Bolts 152 are arranged on the first fixing plate 12, the second fixing plate 13, the third fixing plate 14 and the telescopic plate 143. Threaded holes adapted to the bolts 152 are formed on the first fixing plate 12, the second fixing plate 13, the third fixing plate 14 and the telescopic plate 143, and the bolts 152 are installed in the threaded holes.

[0035] A first plugging plate 124 for plugging the threaded holes thereon is movably arranged on the first fixed plate 12. The first plugging plate 124 extends above the first fixed plate 12 and is fixedly provided with a first trigger plate 123. A first spring 125 is arranged between the first plugging plate 124 and the first fixed plate 12; a plurality of through holes adapted to the bolts 152 on the first fixed plate 12 are formed in the first plugging plate 124. When the first fixed plate 12 does not reach the highest point, the first spring 125 and the first plugging plate 124 move upward together with the first fixed plate 12, and the through holes on the first plugging plate 124 are offset from the threaded holes on the first fixed plate 12. At this time, the bolts 152 cannot move. When the first fixed plate 12 reaches the highest point, the first trigger plate 123 drives the first plugging plate 124 to move downward under the extrusion of the ground beam steel reinforcement cage. The through holes on the first plugging plate 124 are aligned with the threaded holes on the first fixed plate 12. At this time, the bolts 152 can be rotated to fix the steel bars.

[0036] A second trigger plate 133 for plugging the fixing groove 151 thereon is arranged on the second fixed plate 13. The second trigger plate 133 is rotatably installed on the second fixed plate 13. A second plugging plate 134 for plugging the threaded holes thereon is movably arranged on the second fixed plate 13. A plurality of through holes adapted to the bolts 152 are formed in the second plugging plate 134; a second spring 135 is arranged between the second plugging plate 134 and the second fixed plate 13, and a pulling rope is connected between the second trigger plate 133 and the second plugging plate 134. When the top of the first fixed plate 12 abuts against the top inside the ground beam steel reinforcement cage, the distance between the end of the second fixed plate 13 and the mounting seat 11 is 1.5 times the height of the ground beam. At this time, the steel bars on the outer side of the bearing beam are inserted into the ground beam steel reinforcement cage. The vertical part of the outer steel bar is located in the fixing groove 151 on the first fixed plate 12, and the bent part of the outer steel bar is in the fixing groove 151 on the second fixed plate 13. The end of the steel bar will push the second trigger plate 133 and extend out of the fixing groove 151. The second trigger plate 133 drives the second plugging plate 134 to move through the pulling rope. The through holes on the second plugging plate 134 are aligned with the threaded holes on the second fixed plate 13. At this time, the bolts 152 can be rotated to fix the steel bars.

[0037] II. The fixing component of the embodiment of the present invention mainly consists of a plurality of fixing units 1. The plurality of fixing units 1 are arranged side by side, and two adjacent fixing units 1 are fixed together through a connecting structure. The connecting structure includes a first wedge block 111, a second wedge block 112, and a tenon block 113. The first wedge block 111 is fixed on the second fixing plate 13 of one of the fixing units 1; the tenon block 113 is fixedly arranged on the second wedge block 112, and a tenon groove is formed on the mounting seat 11 of the other fixing unit 1. The tenon block 113 is slidably connected to the tenon groove, so that the second wedge block 112 is slidably arranged on the mounting seat 11 of the other fixing unit 1; a tenon strip is arranged on the inclined surface of the second wedge block 112, and a tenon groove is formed on the inclined surface of the first wedge block 111. The tenon strip and the tenon groove are connected, so that the first wedge block 111 and the second wedge block 112 are abutted against each other.

[0038] The fixing component is used for fixing the steel bars of the top-layer load-bearing beam and the bottom-layer load-bearing beam to the ground beam steel reinforcement cage. When it is used for the steel bars of the bottom-layer load-bearing beam and the ground beam steel reinforcement cage, it is the bottom-layer steel bar fixing component 2. When it is used for the steel bars of the top-layer load-bearing beam and the ground beam steel reinforcement cage, it is the top-layer steel bar fixing component 3.

[0039] The bottom-layer steel bar fixing component 2 is located below the top-layer steel bar fixing component 3. In this embodiment, the bottom-layer steel bar fixing component 2 and the top-layer steel bar fixing component 3 are arranged horizontally at 90°. A hook 31 is arranged on one of the fixing units 1 of the top-layer steel bar fixing component 3, and a groove adapted to the hook 31 is formed on one of the fixing units 1 of the bottom-layer steel bar fixing component 2.

[0040] III. The fixing method of the embodiment of the present invention includes the following steps:

[0041] (1) When fixing the steel bars of the bottom-layer load-bearing beam and the ground beam steel reinforcement cage:

[0042] (1)When tying the ground beam steel reinforcement cage, first tie the ground beam steel reinforcement cage and bend the load-bearing beam steel bars. The bent part of the steel bars outside the load-bearing beam is not less than 1.5 times the height of the ground beam steel reinforcement cage. At this time, the third fixing plate 14 is parallel to the second fixing plate 13, and the fixing unit 1 is in an L shape. Send a fixing unit 1 of the bottom steel bar fixing assembly 2 into the ground beam steel reinforcement cage. The two vertical sections of the stirrups on the outer layer of the ground beam steel reinforcement cage are respectively stuck in the fixing grooves 151 on the first fixing plate 12 and the fixing grooves 151 on the second fixing plate 13. Rotate the first screw mechanism 121. The first screw mechanism 121 pushes the first fixing plate 12 to move upward and drives the first dial 122 to rotate. The first dial 122 drives the second dial 132 adapted to it to rotate, and then drives the second screw mechanism 131 to rotate. The second screw mechanism 131 pushes the second fixing plate 13 to move outward, and the moving distance of the second fixing plate 13 is 1.5 times the moving distance of the first fixing plate 12. While the second dial 132 is rotating, the second dial 132 drives the third dial 142 adapted to it to rotate and drives the third screw mechanism 141 to rotate. The third screw mechanism 141 pushes the third fixing plate 14 to move outward, and at the same time the telescopic plate 143 also extends outward. The moving distance of the third fixing plate 14 is the same as the moving distance of the first fixing plate 12.

[0043] (2)When the top of the first fixing plate 12 abuts against the top inside the ground beam steel reinforcement cage, the distance between the end of the second fixing plate 13 and the mounting seat 11 is 1.5 times the height of the ground beam. At this time, insert the steel bars outside the load-bearing beam into the ground beam steel reinforcement cage. The vertical part of the outer steel bars is located in the fixing groove 151 on the first fixing plate 12, and the bent part of the outer steel bars is in the fixing groove 151 on the second fixing plate 13. The end of the steel bars will push the second trigger plate 133 and extend out of the fixing groove 151. The second trigger plate 133 drives the second blocking plate 134 to move through the pull rope. The through hole on the second blocking plate 134 is aligned with the threaded hole on the second fixing plate 13.

[0044] (3)After the third fixing plate 14 stops moving, rotate the third fixing plate 14 upward. The third fixing plate 14 stands up parallel to the first fixing plate 12. The included angle between the third fixing plate 14 and the telescopic plate 143 is a right angle. The third fixing plate 14 can abut against the inner wall of the stirrup. At this time, the fixing unit 1 is in an F shape. When rotating the third fixing plate 14, the pushing block 144 on the third fixing plate 14 rotates. The slope on the pushing block 144 gradually pushes the locking rod 145, so that the locking rod 145 extends to the outside of the telescopic plate 143 and inserts into the mortise hole on the second fixing plate 13 to fix the telescopic plate 143 and prevent the telescopic plate 143 from stretching or shortening randomly.

[0045] (4) Then, send the bottom ends of the outer steel bars of the bearing beam into the ground beam steel reinforcement cage, and the bent parts of the outer steel bars are located in the fixing grooves 151 on the second fixing plate 13. The length of the bent part of the outer steel bars of the bearing beam exceeds 1.5 times the height of the ground beam. The end of the steel bar will push the second trigger plate 133 and extend out of the fixing groove 151. The second trigger plate 133 drives the second sealing plate 134 to move through a pull rope. The through hole on the second sealing plate 134 is aligned with the threaded hole on the second fixing plate 13. The vertical part of the outer steel bar is located in the fixing groove 151 on the first fixing plate 12, the vertical part of the inner steel bar is located in the fixing groove 151 on the third fixing plate 14, and the horizontal part of the inner steel bar is located in the fixing groove 151 on the telescopic plate 143. At this time, rotate the bolts 152 on the first fixing plate 12, the second fixing plate 13, the third fixing plate 14, and the telescopic plate 143. The bolts 152 squeeze the first fixing plate 12, the third fixing plate 14, and the telescopic plate 143. The first fixing plate 12, the second fixing plate 13, the third fixing plate 14, and the telescopic plate 143 deform to fix the steel bars.

[0046] (5) When the second fixing plate 13 moves, it will drive the first wedge block 111 to move. The first wedge block 111 pushes the second wedge block 112 to move outward from the mounting seat 11 to determine the distance between two adjacent fixing units 1. After the previous fixing unit 1 is fixed, send the adjacent fixing unit 1 into the interior of the ground beam steel reinforcement cage, and the tenon block 113 on the previous fixing unit 1 is inserted into the mortise groove on the mounting seat 11 of the adjacent fixing unit 1 to fix the two adjacent fixing units 1 together.

[0047] (6) Repeat the operation, and multiple fixing units 1 form the bottom layer steel bar fixing assembly 2.

[0048] (2) When fixing the top layer bearing beam steel bars and the ground beam steel reinforcement cage:

[0049] The fixing method of the top layer bearing beam steel bars and the ground beam steel reinforcement cage is the same as the above-mentioned fixing method of the bottom layer bearing beam steel bars and the ground beam steel reinforcement cage. During fixing, only the spatial layout needs to be adjusted according to the horizontal angle of the top layer bearing beam steel bars to achieve the fixing between the top layer bearing beam steel bars and the ground beam steel reinforcement cage. In this embodiment, the bent part of the top layer bearing beam steel bars is perpendicular to the bent part of the bottom layer bearing beam steel bars in the horizontal direction. Therefore, the bottom layer steel bar fixing assembly 2 and the top layer steel bar fixing assembly 3 are arranged horizontally at 90° to each other, which is more convenient for fixing.

[0050] Finally, install multiple fixing units 1 into the ground beam steel reinforcement cage to form the top layer steel bar fixing assembly 3, and the hooks 31 on the top layer steel bar fixing assembly 3 are inserted into the grooves on the bottom layer steel bar fixing assembly 2 to connect the top layer steel bar fixing assembly 3 and the bottom layer steel bar fixing assembly 2 together, and then fix the bearing beam steel bars together to form the bottom of the bearing beam steel reinforcement cage for continuing to build the bearing beam steel reinforcement cage upward.

[0051] In addition, it should be noted that for the specific embodiments described in this specification, the shapes and names of the components can be different. The above content described in this specification is only an example of the structure of the present invention.
