Abstract
Description
Technical Field
[0001] The utility model belongs to the field of anti-floating anchor rod construction, and in particular relates to a separate device for anti-floating anchor rod concrete construction. Background Art
[0002] When the groundwater level rises or there is moisture in the soil, the moisture seeps into the basement floor. When the building's own weight is not enough to resist the buoyancy of the groundwater, the building floats. Usually, drainage, weight-bearing, anti-floating piles, anti-floating anchors and other methods are used to achieve the purpose of anti-floating. Among them, anti-floating anchors are widely used because of their strong adaptability to the formation, ability to disperse stress, ease of construction, high bearing capacity in hard rock and soil layers, short construction period, and low cost. The anti-floating anchor must pass through the basement waterproof layer. The quality of the waterproof structure at the junction of the anti-floating anchor and the base is directly related to whether the basement leaks (see Figure 1 ), the junction between the bottom plate waterproof layer and the anti-floating anchor rod is difficult to fit tightly. Once the asphalt waterproof paste fails to be completely sealed, leakage will occur. Utility Model Content
[0003] In view of the problems existing in the prior art, the utility model provides a separate device for anti-floating anchor concrete construction, which solves the leakage problem at the junction of the anti-floating anchor and the bottom plate and ensures the construction quality at the junction of the anti-floating anchor and the bottom plate.
[0004] The utility model provides a separate device for anti-floating anchor concrete construction, which is a cylindrical structure, comprising a first cylinder (vertical section), a first truncated inverted cone cylinder portion connected to the top of the first cylinder, a second cylinder portion connected to an opening on the top plane of the first truncated inverted cone cylinder portion, a second truncated inverted cone cylinder portion connected to the top of the second cylinder portion, and a sealing plate covering the top of the second truncated inverted cone cylinder portion, wherein the sealing plate is provided with an opening, and the cylindrical structure is formed by two basically symmetrical semi-cylinders cut longitudinally, and each semi-cylinder is composed of a first cylinder, a first truncated inverted cone cylinder portion, a second cylinder portion, a second truncated inverted cone cylinder portion, and a half of a sealing plate which are connected in sequence.
[0005] Furthermore, a hoop for fixing the two half-cylinders together is provided at the second cylinder portion. The hoop can be a hoop component well known to those skilled in the art.
[0006] Furthermore, the diameter of the bottom of the first truncated inverted cone cylinder portion is equal to the diameter of the first cylinder body, and the inner diameter of the first cylinder body surrounded by the two halves is equal to or slightly larger than the diameter of the anti-floating anchor rod (anchor bar and the surrounding solidified concrete) to be constructed. The diameter of the top surface of the first truncated inverted cone cylinder portion is larger than the diameter of the second cylinder body portion, and the diameter of the bottom of the second truncated inverted cone cylinder portion is equal to the diameter of the second cylinder body portion. The cone bottom angle (the angle between the diameter and the side surface) of the first truncated inverted cone cylinder portion and the second truncated inverted cone cylinder portion can be 30-80 degrees, preferably about 45-75 degrees, for example 60 degrees.
[0007] Further, the top plane of the first truncated inverted cone cylinder portion is used to control the elevation of the bottom slab concrete.
[0008] The two half cylinders can be welded from steel plates with a thickness of 5±1mm.
[0009] Further, the height of the first truncated inverse cone cylinder portion is greater than 300 mm, for example, 400-500 mm. The height of the second truncated inverse cone cylinder portion is generally smaller than the height of the first truncated inverse cone cylinder portion, for example, 10-60 mm smaller.
[0010] The sealing plate can be in the shape of a truncated cone, which is smaller at the top and larger at the bottom. The bottom angle of the truncated cone can be 15±5 degrees.
[0011] Furthermore, the sealing plate is provided with through holes for the top ends of the anchor bars of the anti-floating anchor rod to pass through, and the number of the through holes corresponds to the number of the anchor bars of the anti-floating anchor rod.
[0012] In one embodiment, the number of through holes is 2, one is provided on each side of the sealing plate, and the corresponding anchor bars are 2. The diameter of the anchor bars is generally 32 mm.
[0013] The function of the first cylinder is: during the construction of the anti-floating anchor rod, there may be a slight deviation in verticality. After the first straight cylinder is inserted into the constructed anti-floating anchor rod part, its verticality can be properly corrected at the top of the anti-floating anchor rod, so as to ensure that the anti-floating anchor rod is in an axially tensile stress state as much as possible.
[0014] The height of the first cylinder can be 100 mm ± 20 mm, preferably 100 mm ± 10 mm. The height of the second cylinder can be, for example, 50-200 mm, preferably 80-150 mm, for example, about 100 mm.
[0015] In the first truncated inverted cone cylinder portion and the second truncated inverted cone cylinder portion, the inverted cone cylinder structure forms a "mortise and tenon" installed like a wooden structure, which enhances the embedding effect of the anti-floating anchor rod and the bottom plate concrete; the cone surface with a larger top and a smaller bottom can use the gravity of the water itself to reduce the upward penetration of water.
[0016] The arc of each half of the first cylinder and the second cylinder is preferably π, so that the two halves form a cylinder after being connected.
[0017] During the construction of the anti-floating anchor rod, there is a slight deviation in verticality. After the device is inserted into the constructed anti-floating anchor rod, the first cylinder section and the second cylinder section can correct its verticality at the top of the anti-floating anchor rod to ensure that the anti-floating anchor rod is in an axially tensile stress state.
[0018] After the soil part of the anti-floating anchor rod is constructed, this device can be used to continue the construction of the top of the anti-floating anchor rod. When the top of the anti-floating anchor rod is completed, the anti-floating anchor rod as a whole is like a protruding nail firmly nailed into the soil. At this time, the top of the anti-floating anchor rod is wrapped in the construction base plate concrete. The top of the anti-floating anchor rod has a pre-formed cone surface, which is firmly embedded in the base plate concrete like the "mortise and tenon" installed in the wooden structure. This construction process avoids the intersection of the anti-floating anchor rod and the base plate. If the construction is improper, the waterproof effect at the anchor bar is not good. The setting of this device solves the connection problem at the intersection of the anti-floating anchor bar in advance.
[0019] Beneficial effects of the utility model:
[0020] The utility model provides a separate type device for anti-floating anchor concrete construction, which adopts a split type and uses two symmetrical semi-cylinders to wrap the top of the anti-floating anchor. There is no soil or other debris inside the entire cylindrical structure, and the first truncated inverted cone cylinder part and the second truncated inverted cone cylinder part prevent lateral soil from invading the anti-floating anchor. Then, anti-seepage concrete is poured into the cylindrical structure to enhance the bonding ability of the junction between the anti-floating anchor and the concrete. The anti-seepage concrete in the device is solidified into one with the concrete outside the device, thereby ensuring the construction quality of the junction between the anti-floating anchor and the bottom plate. The conical surface formed by the first truncated inverted cone cylinder part and the second truncated inverted cone cylinder part, which is larger at the top and smaller at the bottom, can reduce the upward infiltration of water by the gravity of the water itself. At the same time, the first truncated inverted cone cylinder part and the second truncated inverted cone cylinder part enable the concrete inside the cylindrical structure to form an inverted cone, thereby enhancing the embedding effect of the anti-floating anchor and the bottom plate concrete, so that the concrete inside the cylindrical structure is firmly embedded in the bottom plate concrete. The utility model provides a separate anti-floating anchor rod concrete construction device, which achieves close fitting between the anti-floating anchor rod and the bottom plate concrete, thereby avoiding leakage of the bottom plate.
