Abstract
The invention relates to a foundation pile main reinforcement distribution ring applied to foundation file uplifting-resistant static load tests and anchor pile method foundation pile compression-resistant static load tests. In above tests, the main reinforcements of the foundation pile are firmly connected with a counterforce device. An existing connection manner is that a hanging plate is lap-welded with steel reinforcements. The connection manner has the defects that: 1, the filed welding quality is difficult to ensure; 2, when loading, the reinforcements are not straight and parallel, such that the main reinforcements is nonuniform in stress, and the individual main reinforcement may be broken in advance, and thus causing the test failure. The main reinforcement distribution ring is formed by hole rings 1, a central steel cylinder 2 and connection rib plates 3 welded together (referring to the attached drawing of the abstract). The hole rings are formed by cutting a thin steel plate, and the holes are distributed in accordance with the foundation pile main reinforcements. After penetrating through the hole rings 2, the main reinforcements are clamped by anchorage devices or nuts. When in use, drawing force from a main pull rod penetrating through the central steel cylinder 2 is uniformly distributed to main reinforcements by the main reinforcement distribution ring.
Description
Technical field
The present invention can be used for the technical fields such as extracting of foundation pile resistance to plucking static loading test, anchored pile-testing method foundation pile compressive static load test and foundation pile.
Background technology
Foundation pile resistance to plucking static loading test, anchored pile-testing method foundation pile compressive static load test need to firmly be connected the main muscle of foundation pile with counterforce device.Existing connected mode is mainly link plate+bar splicing weldering.There is following disadvantage in this connected mode: 1. Site Welding difficult quality guarantee; 2. while loading, each main muscle is in non-straight, not parallel state.Due to the main muscle unbalance stress of foundation pile, easily cause indivedual main muscle to be pulled off in advance, make test failure.Therefore, need to there is a kind of new connected mode, can make main muscle uniform stressed, ensure that above-mentioned success of the test carries out.
Summary of the invention
The present invention is welded to form by orifice ring 1, center steel cylinder 2 and some connection gussets 3.Orifice ring 2 is formed by steel plate cutting, and the distribution in hole is consistent with the distribution of the main muscle of foundation pile.Main muscle is through after orifice ring, and available ground tackle or nut clamp.When use, the pulling capacity transmitting through the main tie of center steel cylinder is assigned on every main muscle equably by main muscle distribution rings.
Brief description of the drawings
Fig. 1 is a kind of main muscle distribution rings schematic diagram for foundation pile drawing.
Claims (1)
1. be by the custom-designed main muscle distribution rings of drawing foundation pile, center main pull bar can be transmitted pulling capacity be assigned to equably on every main muscle by this main muscle distribution rings.
