Abstract
The utility model relates to an expansion anchor bolt, in particular to a fluid pressure-increasing expansion anchor bolt. The characteristics of the expansion anchor bolt are as follows: the expansion anchor bolt is at least composed of an expandable sealing vessel 5 and an expansion piece 4 which surrounds the expandable sealing vessel 5; when in use, fluid is filled in the expandable sealing vessel 5 and the pressure is increased, so as to lead the expansion piece 4 to expand outwards; at the same time as the surrounding earth and sand rocks are compacted and compressed, the anchor bolt obtains a shape of a reverse wedge. The expandable sealing vessel 5 can be made of rubber pipes or soft metals with good ductility. The bottom end of the expansion piece 4 can adopt the structure of flat end or pointed end, and the expansion piece 4 can be made of rigid or flexible materials. The pressure-increased fluid which is filled in the expandable sealing vessel 5 can be air, water or certain serous fluid which can be solidified and formed. The fluid pressure-increasing expansion anchor bolt can also be used as bases of various large-sized equipments which are used for buildings and are used in a flowing manner.
Description
Affiliated technical field
What the utility model was related is a kind of expansion anchor, particularly the pressurized with fluid expansion anchor.
Background technique
Crab-bolt is to be embedded in the device that is used for fixing object in the floor body of wall of underground or building.
We know that a kind of architectural EXPANSION ANCHOR BOLTS commonly used is arranged, but it only is fit to be embedded in use in the harder material (as brick material, concrete etc.), and its degree of depth of burying underground also can be very limited.
Under a lot of situations, crab-bolt is to be embedded in the underground use hard to predict of its material soft or hard, because the volume of its wedging or the degree of depth of burying underground can have a strong impact on the fastness and the reliability of crab-bolt, therefore, the thing that an extremely is wasted time and energy is not only in burying underground of crab-bolt, and is difficult to hold the crab-bolt volume or the depth of burying that needs wedging.
Summary of the invention
For this reason, the utility model provides a kind of pressurized with fluid expansion anchor, and its major character is:
1, it is made of expandable seal container 5 and the expansion piece 4 that is looped around around 5 at least.During use, in expandable seal container 5, inject pressurized with fluid, make expansion piece 4 outside distendings, when compacting, compressing the ambient earth sandstone, make crab-bolt obtain wedge shape.
2, above-mentioned expandable seal container 5 can be made of rubber pipe.
3, for this pressurized with fluid expansion anchor of permanent use, for preventing fluid seepage under high pressure, above-mentioned expandable seal container 5 can be selected ductility soft metal (as aluminum pipe) making preferably for use.
4, as EXPANSION ANCHOR BOLTS, the tubular structure that axially cracks in ring week can be made in the bottom of above-mentioned expansion piece 4.
5, the bottom of above-mentioned expansion piece 4 can be the tack structure, as EXPANSION ANCHOR BOLTS, will hole in advance during use, and crab-bolt is embedded in expands in the hole then fixes.
6, the bottom of above-mentioned expansion piece 4 also can be the tip structure, uses the time image chock directly to be driven underground like that, and it is fixing to expand then.
7, expansion piece 4 not only can be made of rigid material, and also available tensile strength higher flexible material is as making such as various fibre cloth, textile rope, wire rope.Not only can weight reduction, reduce cost owing to can produce rough compression face behind the flexible material compressive deformation, therefore can improve frictional force to a great extent, thereby improve the fastness of crab-bolt.
8, the pressure fluid in the above-mentioned injection expandable seal container 5, certain slurries that can be air, water or curable moulding are as cement slurry, magnesite slurry, paste resin etc.Empty G﹠W is used for using repeatedly crab-bolt, and the crab-bolt that the slurries of curable moulding are used for disposably and permanently using.
9, can obtain required anti-pressure ability with expanding owing to have this crab-bolt of rigidity expansion piece 4, it does not need to beat as pile very deeply, so it can be used as building and the basis of the various main equipments (as: building various backstay type machinery apparatus such as fixed tower machine, wind-driven generator, oil pumping unit, trepan, Large Radar) of the use of flowing.Not only can raise the efficiency, reduce cost, also can avoid using Cast-in-place concrete basis and cause ample resources waste and environmental pollution.
Compare with common crab-bolt with EXPANSION ANCHOR BOLTS, the advantage of this pressurized with fluid expansion anchor is: a, easy to loading and unloading can the use repeatedly; B, can obtain high fastness and reliability; C, the regulating and controlling swelling pressure easily, thus required fastness and reliability obtained; D, cost are low, in light weight, of many uses.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is first embodiment's of pressurized with fluid expansion anchor a three-dimensional laterally sectional elevation.
Fig. 2 is second embodiment's of pressurized with fluid expansion anchor a three-dimensional laterally sectional elevation.
1. end caps among the figure; 2. tube head; 3. fluid passage; 4. the lower end is the expansion piece of tack; 5. expandable seal container; 6. pipe plug.
Embodiment
What Fig. 1 described is: the lower end of its expansion piece is the basic structure of the pressurized with fluid expansion anchor of tack.
Among Fig. 1, the 1st, end cap; The 2nd, be fixed on the tube head that the end cap below is used for connecting expandable seal container 5; 3 are arranged on the fluid passage on the end cap, and it links to each other with the cavity of expandable seal container 5; The 4th, the lower end is the expansion piece of tack, its not only available rigid material is as material such as reinforced concrete, metals, the higher flexible material of also available tensile strength as: making such as various fibre cloth, textile rope, wire rope, lower end be available welding between expansion piece 4 and the end cap 1 of tack, hinged, bolt is connected etc.; When expandable seal container 5 usefulness rubber pipes or metal tube were made, its upper end and tube head 2 were tightly connected, lower end and pipe plug 6 be tightly connected (can banding).
What Fig. 2 described is: the lower end of its expansion piece is the pressurized with fluid expansion anchor of tip, and during use, it can directly be driven underground as chock, and it is fixing to expand then.
Among Fig. 2, the 1st, end cap; .2 be to be fixed on the tube head that the end cap below is used for connecting expandable seal container 5; 3 are arranged on the fluid passage on the end cap, and it links to each other with the cavity of expandable seal container 5; 4a is that the lower end is the expansion piece of tip, but it with end cap 1 between banding be connected, be threaded or welding etc.; When expandable seal container 5 usefulness rubber pipes or metal tube were made, its upper end and tube head 2 were tightly connected, lower end and pipe plug 6 be tightly connected (can banding).
