DETAILED DESCRIPTION

[0030] The technical scheme in the embodiment of the utility model will be clearly and completely described below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of protection of the utility model.

[0031] As Figures 1 to 2As shown in Embodiment 1, an airport concrete construction ground anchor mold device includes: two arc-shaped parts 1, which can be parallelly closed from both sides of the ground anchor steel bar 7 to form a mold with the same size as the ground anchor pit.

[0032] The closed structure 2 is divided into two parts, which are respectively set on both sides of the inner wall of the two arc-shaped parts 1, and can lock the two arc-shaped parts after they are closed.

[0033] The semi-circular groove 3 has the same size as the ground anchor steel bar 7. Two grooves are provided at the bottom of the two arc-shaped parts 1. After the two arc-shaped parts 1 are closed, the ground anchor steel bar 7 is clamped from both sides.

[0034] During the specific construction process, vertical supports are set up to vertically fix the ground anchor steel bars 7, so as to prevent the ground anchor steel bars 7 from tilting during the closing of the two arc-shaped parts 1, which would hinder the operation of the construction personnel. During the construction process, the two arc-shaped parts 1 are closed to form a mold of the same size as the ground anchor pit, and the ground anchor steel bars 7 are clamped in the semi-circular grooves 3 on the two arc-shaped parts 1. Then, the setting of the closed structure 2 prevents the two arc-shaped parts 1 from having horizontal displacement, which would cause large errors during the subsequent concrete pouring and prevent the ground anchor pit from being formed.

[0035] The closing structure 2 is set as a parallel pull buckle, which can lock the two arc-shaped parts 1 by fastening the other arc-shaped part 1 inside one arc-shaped part 1 after the two arc-shaped parts 1 are closed.

[0036] The parallel buckle can keep the two arc-shaped parts 1 in a closed state, so that the two arc-shaped parts 1 can be closed into a complete ground anchor mold and maintain good compressive strength. After the concrete ground anchor pit is formed, it is formed at the same time and avoids the need for secondary repair of the ground anchor pit, saving construction time. At the same time, it can be easily and quickly removed. After the parallel buckle is released, the two arc-shaped parts 1 can be pulled out of the concrete ground anchor pit, so that they can be reused and reduce construction costs.

[0037] like Figures 2 to 6 As shown in Embodiment 2, an airport concrete construction ground anchor mold device further includes: a support component 4, which consists of two identical parts arranged in parallel and staggered on opposite sides of two arc-shaped parts 1. After the two arc-shaped parts 1 are closed, the support component 4 can support the ground anchor steel bar 7 at the highest position relative to the two arc-shaped parts 1, so that the ground anchor steel bar 7 and the two arc-shaped parts 1 remain in a stable state.

[0038] In the repeated use, the support assembly 4 can generate upward supporting force on the ground anchor steel bar 7 after the two arc-shaped parts 1 are closed, and generate downward interaction force on the two arc-shaped parts 1, so that a more stable state is formed between the mold composed of the ground anchor steel bar 7 and the two arc-shaped parts 1, the error generated during subsequent pouring of concrete is reduced, and the construction precision is improved.

[0039] The two parts of the support assembly 4 each include a fixed rod 4-1, one end of which is fixedly arranged on the inner wall surface of one of the arc-shaped parts 1, and the other end extends into the range of the other arc-shaped part 1 and passes through the bottom of the middle part of the ground anchor steel bar 7;

[0040] A rotating shaft 4-2 is rotatably arranged at the end of the fixed rod 4-1 facing the ground anchor steel bar 7;

[0041] A rotating rod 4-3 passes through the rotating shaft 4-2 at the top and can contact the middle part of the ground anchor steel bar 7, and during the closing process of the two arc-shaped parts 1, the ground anchor steel bar 7 can contact and press the rotating rod 4-3 to make it turn over;

[0042] A telescopic rod 4-4 is arranged at the bottom of the rotating rod 4-3 and forms an angle with the top of the rotating rod 4-3, the inside of the telescopic rod 4-4 is provided with a first spring 4-5, and the bottom of the telescopic rod 4-4 can abut against the inner wall surface of the two arc-shaped parts 1, when the two arc-shaped parts 1 are closed, the bottom of the telescopic rod 4-4 on one of the arc-shaped parts 1 can be rotated to the inner wall surface of the other arc-shaped part 1.

[0043] During the closing process of the two arc-shaped parts 1, the middle part of the ground anchor steel bar 7 contacts and presses the two parts of the support assembly 4, so that the two rotating rods 4-3 are turned over at the same time, the telescopic rod 4-4 at the bottom of the rotating rod 4-3 is rotated to the inner wall of the other arc-shaped part 1 along the inner wall of the arc-shaped part 1, the first spring 4-5 in the telescopic rod 4-4 is compressed, and the bottom of the telescopic rod 4-4 abuts against the inner wall of the other arc-shaped part 1, so that the top of the rotating rod 4-3 has an upward pushing force on the ground anchor steel bar 7, so as to form a more stable state between the mold composed of the ground anchor steel bar 7 and the two arc-shaped parts 1, and after the parallel pull buckle is buckled, the stable upward pushing force on the ground anchor steel bar 7 can be continuously maintained.

[0044] The bottom of the telescopic rod 4-4 is provided with a triangular block 4-6; a concrete construction ground anchor mold device for an airport, further comprising: two groups of ratchet teeth 5 arranged on the inner wall surfaces of the two arc-shaped parts 1, when the two arc-shaped parts 1 are closed, the triangular block 4-6 at the bottom of the telescopic rod 4-4 on one of the arc-shaped parts 1 can be inserted into one group of ratchet teeth 5 on the other arc-shaped part 1.

[0046] The telescopic rods 4-4 are provided with the second springs 6 between the inner walls of the corresponding arc-shaped parts 1.

[0047] When the telescopic rods 4-4 at the bottom of one arc-shaped part 1 are rotated to the inner wall surface of the other arc-shaped part 1, the telescopic rods 4-4 on both sides are locked by the ratchet teeth 5 of the other arc-shaped part 1, and the second springs 6 on both sides are stretched, the tension of the second springs 6 is transmitted to the triangular blocks 4-6 at the bottom of the telescopic rods 4-4, so that the triangular blocks 4-6 on both sides generate a thrust force to the ratchet teeth 5 of the other arc-shaped part 1, so that the interaction force between the two arc-shaped parts 1 is closed inward, the two arc-shaped parts 1 can be more closely fitted, and the ground anchor steel bars 7 always maintain the extrusion force on the rotating rod 4-3, so that the bottom of the telescopic rods 4-4 applies a thrust force to the inner walls of the two arc-shaped parts 1, the ground anchor mold formed by the ground anchor steel bars 7 and the two arc-shaped parts 1 remains in a stable state, avoids the ground anchor mold from floating up due to the buoyancy generated during the concrete vibrating process, so that the hole formed by the semicircular groove has a gap, reduces the construction error, improves the construction accuracy, enables the ground anchor pit to be formed at one time, avoids the need for secondary modification of the ground anchor pit, and further saves the construction time.
