Description

Technical Field

[0001] The invention relates to the technical field of building structure foundations, and in particular to a steel structure tool-type anchor point and an installation and removal method thereof. Background Art

[0002] Anchor structures are often used in temporary buildings or construction sites. Temporary anchor points are a major problem faced by anchor structures. Currently, concrete anchor points are often used as temporary anchor points. However, temporary anchor points only need to be used once. If concrete anchor points are used, it will not only cause a large waste and cannot be reused, but also require a certain amount of time for maintenance, causing certain damage to the environment and bringing certain economic losses.

[0003] When it comes to occupying agricultural land around buildings, the installation of temporary concrete anchor points is subject to greater restrictions, and the structural form of temporary anchor points is often not standardized, which can easily lead to safety hazards. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a steel structure tool anchor point and its installation and removal method, so as to achieve the purpose of not damaging the environment, being reusable and having reliable structural force.

[0006] Furthermore, the bolt comprises a screw rod, one end of which passes through the upper split bottom plate and the lower split bottom plate in sequence, and the other end of the screw rod is provided with a thread and is rotatably connected to the upper surface side plate through a nut.

[0007] Furthermore, one end of the screw rod for connecting the upper and lower split bottom plates is provided with a square end block, and one side of the upper and lower split bottom plates detachably connected to each other is provided with a first square hole for passing the square end block.

[0008] Furthermore, the length of the square end block is L and the width is W, the length of the first square hole is L1 and the width is W1, wherein L<L1 and W<W1 and W1<L.

[0009] Furthermore, a screw top flat head on which a rotary wrench can be mounted is provided at the top of the screw. By mounting the rotary wrench on the screw top flat head, the screw can be rotated, thereby driving the square end block to rotate.

[0010] Furthermore, a second square hole for passing the square end block is formed on the upper surface side plate.

[0011] Furthermore, the width of the second square hole is smaller than the diameter of the nut.

[0012] Furthermore, the upper split bottom plate and the lower split bottom plate are connected to the first side plates arranged on the left and right through hinges respectively.

[0013] Furthermore, the upper surface side plate is located between the two first side plates.

[0014] Furthermore, the main beam is located between the two first side plates, and both ends of the main beam are located in the middle of the two first side plates.

[0015] A method for installing and removing a tool-type anchor point of a steel structure comprises the following steps:

[0016] S1. Place the steel structure box including the first side plate, the second side plate, the upper segmented bottom plate, the lower segmented bottom plate, the upper surface side plate and the main beam on the site or bury it in the site;

[0017] S2, insert a bolt with a screw flat head on the top, a thread on the upper end of the screw, and a square end block on the bottom of the screw into the upper surface side plate, and make the square end block pass through the upper split bottom plate and the lower split bottom plate in turn;

[0018] S3. Insert a wrench onto the flat head of the screw and rotate the wrench 90° to drive the square end block at the bottom of the screw to rotate 90° so that the square end block is stuck and fits the bottom of the lower split bottom plate;

[0019] S4. Insert the nut from the flat head of the screw into the upper end of the screw and tighten the nut to fix the bolt;

[0020] S5. Fill the steel structure box with soil until it is full, and backfill the soil around the steel structure box. Finally, connect the cable of the anchor structure to the ear plate on the main beam, thus completing the installation of the tool anchor point of the steel structure.

[0021] T1. Unscrew the nut from the upper end of the screw, then insert a wrench into the flat head of the screw, rotate the wrench 90°, and drive the square end block at the bottom of the screw to rotate 90°, so that the square end block is no longer stuck and fits the bottom of the lower split bottom plate;

[0022] T2. Take out the entire bolt from the lower split bottom plate, upper split bottom plate, and upper surface side plate in turn;

[0023] T3. Remove the cable from the ear plate and lift the ear plate with a hoist. Under the action of gravity, the upper and lower split bottom plates will flip downwards to allow the soil in the steel structure box to flow out, thus completing the removal of the tool anchor point of the steel structure.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The present invention adopts a steel structure box combined with earth filling to effectively resist the cable force of the anchor structure. The structure is reliable in force and can play the role of an anchor point without causing damage to the environment and is not restricted by the installation environment.

[0026] 2. The present invention utilizes a bolt with a screw top flat head on the top and a square end block on the bottom. By rotating the bolt, the upper and lower divided bottom plates at the bottom of the steel structure box can be detachably connected. When the anchor point is removed, the soil in the steel structure box can quickly flow out naturally. This not only has the advantage of convenient dismantling, but also ensures the reusability of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
