Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to an assembled building support seat. Background Art

[0002] The utility model patent with application number: CN201922034082.2 discloses an assembled building support seat structure, which aims to solve the problem that the anchor rod is difficult to be pulled out during removal due to the thorns designed for the existing anchor rod to improve the anchoring force. The technical solution is to set evenly distributed thorn steps on the anchor rod to increase the anchoring force with the thorn steps, and pull out the thorn steps by using the gears that are meshed with the thorns during removal; this method actually provides a power-assisting mechanism for pulling out the anchor rod, thereby providing a greater pulling force, and does not fundamentally solve the contradiction between the large anchoring force requirement and the small removal force requirement; moreover, the thorn steps of the patent are designed to be flat in order to cooperate with the gears, which makes the thorn steps severely squeeze the soil downward when the anchor rod is inserted into the soil, resulting in a significant increase in the insertion resistance, and because the soil is compressed downward during insertion, the anchoring force is also significantly reduced, which is why this thorn structure has not been widely adopted; in addition, when the anchor rod is pulled out, the thorn steps of the patent will bring out a large amount of soil, leaving a relatively obvious pit at the anchoring position. Summary of the invention

[0003] In order to solve the above problems, the utility model provides an assembled building support seat.

[0004] The technical solution includes a bottom plate, a top plate and several groups of anchoring units. The bottom plate and the top plate are both horizontally arranged, and the top plate is supported above the bottom plate. The anchoring unit includes a vertical anchor rod and two arc-shaped racks. Through holes are provided on the top plate and the bottom plate. The anchor rod passes through the top plate and the bottom plate through the through holes. The upper end of the anchor rod extends above the top plate. The two arc-shaped racks are symmetrically arranged on both sides of the anchor rod. One end of the arc-shaped rack is hinged to the bottom plate through a connecting arm, and the hinge shaft is coaxial with the arc-shaped rack. The other end of the arc-shaped rack extends into the through hole on the bottom plate together with the lower end of the anchor rod. A straight rack is fixed on each side of the left and right sides of the anchor rod body. When the anchor rod moves downward, the two straight racks will mesh with the arc-shaped rack on the same side, driving the arc-shaped rack to rotate. The anchor rod is vertically inserted into the soil, and the two arc-shaped racks will be inserted into the soil along a circular trajectory.

[0005] The two arc-shaped racks of the same group of anchoring units are each provided with a threaded hole. The anchoring unit further comprises a connecting rod, and the two ends of the connecting rod can be connected to the threaded holes on the two arc-shaped racks via screws.

[0006] A plurality of upward bolts are fixed on the bottom plate, the top plate is passed through the bolts, and an adjusting nut located below the top plate is screwed on the bolts, and the top plate is supported by the adjusting nut.

[0007] The upper end of the anchor rod is provided with a pulling hole.

[0008] The widths of the tip portion of the arc-shaped rack and the tip portion of the anchor rod are both greater than the widths of their respective toothed portions.

[0009] The utility model provides a greater anchoring force and can pull out the anchor rod with a smaller pulling force during removal, thereby solving the contradiction between the anchoring force and the pulling force during removal, and no obvious pit will be left after removal.

[0013] In conjunction with the accompanying drawings, the utility model includes a bottom plate 1 and a top plate 2 and a plurality of groups of anchoring units. The bottom plate 1 and the top plate 2 are both arranged horizontally, and the top plate 2 is supported above the bottom plate 1. The anchoring unit includes a vertical anchor rod 3 and two arc-shaped racks 4. Through holes are provided on the top plate 2 and the bottom plate 1. The anchor rod 3 passes through the top plate 2 and the bottom plate 1 through the through holes. The upper end of the anchor rod 3 extends above the top plate 2. The two arc-shaped racks 4 are symmetrically arranged on both sides of the anchor rod 3. One end of the arc-shaped rack 4 is hinged to the bottom plate 1 through a connecting arm 5. The hinge shaft is coaxial with the arc-shaped rack 4. The other end of the arc-shaped rack 4 is connected to the bottom plate 1. The lower ends of the anchor rods 3 are extended into the through holes on the base plate 1 together, and this end of the arc-shaped rack 4 and the lower end of the anchor rod 3 are both pointed ends. A straight rack 6 is fixed on each side of the left and right sides of the rod body of the anchor rod 3. When the anchor rod 3 moves downward, the two straight racks 6 will engage with the arc-shaped rack 4 on the same side, driving the arc-shaped rack 4 to rotate, and the anchor rod 3 is vertically inserted into the soil, and the two arc-shaped racks 4 will be inserted into the soil along a circular trajectory; since the two arc-shaped racks 4 are inserted into the soil in an "eight" shape, the arc-shaped rack 4 and the anchor rod 3 are not easy to be pulled out when the base plate 1 is subjected to an upward pulling force, thereby effectively improving the anchoring force.

[0014] The two arc-shaped racks 4 of the same group of anchoring units are each provided with a threaded hole 7, and the anchoring unit also includes a connecting rod 8, the two ends of the connecting rod 8 can be connected to the threaded holes 7 on the two arc-shaped racks 4 through screws; after the anchor rod 3 and the arc-shaped rack 4 are inserted into the soil, the two arc-shaped racks 4 are connected by the connecting rod 8, thereby ensuring that the two arc-shaped racks 4 cannot rotate, and further ensuring that the anchoring unit will not be pulled out.

[0015] A plurality of upward bolts 9 are fixed on the bottom plate 1, and the top plate 2 is passed through the bolts 9. An adjusting nut 10 located below the top plate 2 is screwed onto the bolts 9. The top plate 2 is supported by the adjusting nut 10, and the top plate 2 can be leveled by the adjusting nut 10.

[0016] The upper end of the anchor rod 3 is provided with a pulling hole 11, which is convenient for pulling out the anchor rod 3 during removal.

[0017] The widths of the tip portion of the arc-shaped rack 4 and the tip portion of the anchor rod 3 are both greater than the widths of their respective toothed portions, so as to reduce the resistance of the toothed portions after being inserted into the soil.

[0018] When the utility model is in use, the base plate 1 is placed on the ground, and then the upper end of the anchor rod 3 is hammered to make the anchor rod 3 inserted downward into the soil. In the process of the anchor rod 3 moving downward, when the straight rack 6 on the anchor rod 3 is meshed with the two arc-shaped racks 4, the downward movement of the anchor rod 3 will drive the arc-shaped rack 4 to rotate around the hinge axis, so that the two arc-shaped racks 4 are inserted into the soil with a circular trajectory. After the anchor rod 3 is hammered into place, the anchor rod 3 is deeply embedded in the soil, and the two arc-shaped racks 4 are inserted into the soil in an "eight" shape. At this time, the two ends of the connecting rod 8 are respectively connected to the threaded holes 7 on the two arc-shaped racks 4 of the same group with screws, so that the two arc-shaped racks 4 are connected to form a lock, ensuring that the two arc-shaped racks 4 cannot rotate. At this time, even if the anchor rod 3 is directly pulled out, it cannot be pulled out, thereby further ensuring the anchoring strength.

[0019] When it is necessary to dismantle, remove the connecting rod 8, and then pull the anchor rod 3 upward through the pull plate hole at the upper end of the anchor rod 3. When the anchor rod 3 is pulled upward, the straight rack 6 will drive the two arc-shaped racks 4 to rotate in the opposite direction and pull them out of the soil until the anchor rod 3 is completely pulled out and the anchoring is released.

[0020] The utility model forms an "eight"-shaped anchoring structure after being inserted into the soil through the circular insertion trajectory of the arc-shaped rack 4, so that the anchoring unit is not easy to be pulled out of the soil, providing a greater anchoring force, and the anchor rod 3 and the arc-shaped rack 4 will not excessively squeeze the soil when inserted into the soil, and the insertion resistance is small; when dismantling, the arc-shaped rack 4 can be easily pulled out of the soil with a circular trajectory to release the anchoring, thereby solving the contradiction between the anchoring force and the pulling force during dismantling; moreover, the utility model will not leave obvious holes after dismantling.
