Description

Technical Field

[0001] The utility model relates to an anchor bolt installation and fixing device, belonging to the technical field of building construction. Background Art

[0002] With my country's continued investment in infrastructure such as roads, the mileage of ordinary and expressways is getting longer and longer. In order to ensure driving safety, isolation guardrails are generally built on the edge of the road. The construction process of the isolation guardrail is generally to first fix the L-shaped anchor bolts in the steel cage, and then the concrete truck pours concrete into the steel cage. After the concrete solidifies, the base of the isolation guardrail is bolted to the L-shaped anchor bolts, and then the isolation guardrail is fixed to the adjacent base. The Chinese utility model patent with patent number CN201720606156.3 discloses a highway isolation guardrail that is easy to replace and maintain. It only needs to connect the support rod and the support column through the groove and the elastic force of the spring, which makes it easy and convenient to replace and maintain.

[0003] However, the inventor of the present invention found that the existing technology has the following problems: the four L-shaped anchor bolts that lock the base of the isolation guardrail need to be fixed before the concrete solidifies, and the distance between the bolts needs to be maintained within a certain error range. After the construction workers tie the L-shaped anchor bolts with steel wire, they need to use a tape measure to measure whether the distance is correct. If it is unqualified, rework is required until the distance reaches a reasonable position, resulting in a large workload and low efficiency. Therefore, improvement is needed. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides an anchor bolt installation and fixing device, which can bind and fix the distance between L-shaped anchor bolts within the correct range at one time without rework.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a foundation bolt installation and fixing device, which comprises a placement frame, a fixing component, a jack, a Y-axis level and an X-axis level; the fixing component is placed on the middle surface of the placement frame; the bottom surfaces of both sides of the placement frame are placed on symmetrically arranged jack moving end platforms; the X-axis level is placed on the surface where the long side of the placement frame is located; and the Y-axis level is placed on the surface where the short side of the placement frame is located.

[0007] The fixing components include an anchor bolt positioning plate, a locking nut and an L-shaped anchor bolt; an array of positioning holes are provided on the surface of the anchor bolt positioning plate, and the L-shaped anchor bolts are placed in the positioning holes.

[0008] The L-shaped anchor bolt threaded rod sections located above and below the anchor bolt positioning plate are all threadedly connected with locking nuts.

[0009] After the L-shaped anchor bolts are positioned, they are tied to the steel bars in the steel cage with thin iron wire.

[0010] After the positioning of the L-shaped anchor bolt is completed, a plastic film is provided on the end of the threaded rod.

[0011] The air masses on the Y-axis level and the X-axis level need to be adjusted to the middle at the same time.

[0012] The movable end of the jack needs to be adjusted to a height where the L-shaped anchor bolt is located in the middle of the steel cage.

[0013] The beneficial effect of the utility model is that the distance between adjacent L-shaped anchor bolts is first fixed by using anchor bolt positioning plates and locking nuts, and then the L-shaped anchor bolts are fixed to the steel cage with thin iron wires. This can meet the distance requirements between the L-shaped anchor bolts at one time, avoid rework, and greatly improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0018] The first embodiment of the present invention relates to Figure 1-2 The anchor bolt installation and fixing device shown is characterized in that it includes a placement frame 1, a fixing component 2, a jack 3, a Y-axis level 4 and an X-axis level 5; the fixing component 2 is placed on the middle surface of the placement frame 1; the bottom surfaces of both sides of the placement frame 1 are placed on the symmetrically arranged mobile end platforms of the jacks 3; the X-axis level 5 is placed on the surface where the long side of the placement frame 1 is located; the Y-axis level 4 is placed on the surface where the short side of the placement frame 1 is located; the placement frame 1 is used to place the fixing component 2, the Y-axis level 4 and the X-axis level 5; the fixing component 2 is used to fix the relative position of the L-shaped anchor bolt 23; the jack 3 is used to support and lift the placement frame 1; the Y-axis level 4 is used to detect the front and rear tilt angles of the placement frame 1; the X-axis level 5 is used to detect the left and right tilt angles.

[0019] The second embodiment of the present invention is substantially the same as the first embodiment, with the main feature being further optimization. The fixing component 2 comprises an anchor bolt positioning plate 21, a locking nut 22, and an L-shaped anchor bolt 23. The anchor bolt positioning plate 21 is provided with an array of positioning holes 211, within which the L-shaped anchor bolts 23 are placed. The anchor bolt positioning plate 21 predetermines the relative position and distance between the L-shaped anchor bolts 23. The locking nut 22 ensures that the L-shaped anchor bolts 23 are perpendicular to the anchor bolt positioning plate 21. The L-shaped anchor bolts 23 are secured to the steel cage 6. The positioning holes 211 are used to accommodate the L-shaped anchor bolts 23.

[0020] The threaded rod sections of the L-shaped anchor bolts 23 on the upper and lower sides of the anchor bolt positioning plate 21 are threadedly connected with locking nuts 22; the surface of the locking nut 22 is flush with the surface of the anchor bolt positioning plate 21 to ensure the vertical placement of the L-shaped anchor bolts 23.

[0021] After the L-shaped anchor bolts 23 are positioned, they are tied to the steel bars in the steel cage 6 with thin wires to meet the construction process before pouring concrete and ensure the strength of the L-shaped anchor bolts 23.

[0022] After the L-shaped anchor bolt 23 is positioned, a plastic film is provided on the end of the threaded rod to prevent the concrete from contaminating the L-shaped anchor bolt 23 during the concrete filling process of the steel cage 6, which would result in failure to smoothly install the base on the bolt later.

[0023] The air masses on the Y-axis level 4 and the X-axis level 5 need to be adjusted to the middle at the same time, which means that the placement rack 1 is in a horizontal state, ensuring that the fixing component 2 is in a horizontal state, and then ensuring that the L-shaped anchor bolt 23 is set vertically.

[0024] The moving end of the jack 3 needs to be adjusted to the height where the L-shaped anchor bolt 23 is located in the middle of the steel cage 6 to ensure that the end of the L-shaped anchor bolt 23 is at a consistent distance above the concrete plane to meet the construction process requirements.

[0025] Based on this, a typical working process of the utility model is:

[0026] When the utility model is implemented, Figure 1-2As shown, first use the lock nut 22 to secure the L-shaped anchor bolt 23 to the anchor bolt positioning plate 21. Then, move a pair of jacks 3 to the designed installation position of the L-shaped anchor bolt 23. Then, place the placement frame 1 on the platform of the jack 3 moving axis. At the same time, place the Y-axis level 4 and X-axis level 5 vertically on the surface of the placement frame 1. Adjust the posture of the placement frame 1 according to the air mass on the level until the air mass on the Y-axis level 4 and X-axis level 5 are simultaneously adjusted to the middle position. Next, place the fixing component 2 in the middle of the placement frame 1 and adjust the position appropriately so that the surface of the L-shaped anchor bolt 23 contacts the steel cage 6. Then, use thin wire to tie the L-shaped anchor bolt 23 to the steel cage 6.
