Problems solved by technology

However, the traditional anchor that only uses frictional resistance as the pullout force is not suitable for soils with low frictional resistance.
Therefore, the anti-floating ability in this case is not very ideal

Embodiment 1

[0037] As shown in the figure, a flip-type anti-floating anchor rod is made, which includes a steel pipe 1 and an inverted fork rod 2. The upper end of the steel pipe 1 is welded with an extension steel bar, and the bottom end of the steel pipe 1 is welded with a back-sealing steel plate 3. The side wall of the steel pipe 1 is provided with several groups of through-shaped rewinding channels 4 arranged up and down on the same vertical line perpendicular to the bottom end surface. The rewinding channels 4 are arranged from bottom to top from inside to outside. The inclined shape, that is, inclined from the inside to the outside, the inclination is generally between 30°-60°, and the inclination is made 45° in this embodiment; the inner mouth and outer mouth of the rewinding channel 4 The specifications and sizes are the same, and the cross-section of the rewind channel 4 is rectangular.

[0038] The inverted fork rod 2 includes a long bar 5 and several inverted fork pieces 6, th...

Embodiment 2

[0040] On the basis of Example 1, construction tools are also produced, namely the pull rod 7 and the hook 8; the pull rod 7 includes a main rod 71, a pull hook 72 and a support tube 73, and the mouth of the support tube 73 faces upward and is directly fixed At the lower end of the main rod 71 , the pull hook 72 is directly fixed on the upper end of the main rod 71 to form the pull rod 7 .

[0041] Described suspension hook 8 comprises cross bar 81, outer buckle bar 82, inner buckle bar 83 and buckle hook 84, and described buckle hook 84 is directly fixed on the lower end of inner buckle bar 83, and the upper end of inner buckle bar 83 is directly fixed on the right end of cross bar 81 , an end of the outer mouth bar 82 is directly fixed on the left end of the cross bar 81 to form a suspension hook 8 .

[0042] Correspondingly, a hook hole 85 is dug at the upper end of the long bar 5 in the inverted fork bar 2; the clasp 84 on the hook 8 is inserted into the hook hole 85 durin...

Embodiment 3

[0044] A construction method of an anti-floating anchor bar with flip-flop type, comprising the following steps:

[0045] (1) Carry out the hole forming operation with an auger drilling machine, excavate the hole to the design depth, and the size of the hole is slightly smaller than the outer diameter of the steel pipe 1; in this embodiment, the inner diameter of the hole is made equal to 95%-99% of the outer diameter of the steel pipe 1.

[0046] (2) Slowly insert the steel pipe 1 into the hole until it reaches the rated depth.

[0047] (3) Put the inverted fork rod 2 into the steel pipe 1, and then align the outer ends of each inverted fork piece 6 on the inverted fork rod 2 with each rewinding hole 4 on the same vertical line in sequence.

[0048] (4) Put the pull rod 7 into the steel pipe, and then hold the support tube 73 at the lower end of the pull rod 7 to support the lower end of the long rod 5 of the inverted fork rod 2, and move the pull rod 7 to the rewinding channel...

Abstract

An inverted sheet type anti-floating anchor rod belongs to the technical field of building construction and comprises a steel pipe and an inverted fork rod, extension steel bars are welded to the upper end of the steel pipe, a bottom sealing steel plate is welded to the bottom end face of the steel pipe, and a plurality of sets of inclined through inverted sheet hole channels are formed in the side wall of the steel pipe; the inverted fork rod is formed by fixedly mounting inverted fork sheets on a long-strip rod at an inclined angle; a pull rod and a lifting hook are additionally arranged; during construction, a steel pipe is slowly inserted into a dug hole, then each inverted fork piece on an inverted fork rod is sequentially inserted into each inverted piece hole channel, the inverted fork rod is lifted by a pull rod to enable the inverted fork pieces to be inserted into a soil body on the periphery of the steel pipe, then fine aggregate cement mortar is gradually poured and vibrated, coarse aggregate cement mortar is poured into the upper portion, and the inverted fork pieces and the inverted piece hole channels are formed. And the inverted sheet type anti-floating anchor rod is manufactured through maintenance. The anti-floating structure has the beneficial effects that fine aggregate expansive cement mortar is extruded outside by combining the inverted fork rods with the inverted sheet pore channels, and is extruded with soil around the steel pipe to form irregular concrete blocks, and the irregular concrete blocks and the inverted fork sheets form the anti-floating structure together, so that the anti-floating effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a reversible anti-floating anchor rod. Background technique [0002] Anti-floating anchor rod is a kind of anti-floating measures for underground structures in construction projects. The anti-floating anchor refers to the structural member set up to resist the upward displacement of the building on it. It is related to the level and change of the groundwater level, and is opposite to the direction of the compressive force. At present, the anti-floating anchor construction in China is mainly carried out at the foundation bottom elevation. After the earthwork is excavated to the design elevation, the construction of the anti-floating anchor begins. The construction sequence is: first drill the hole, then hoist the main reinforcement of the anchor, The main reinforcement of the anchor rod extends into the foundation for an anchor length, and finally the foundation is ...
