Abstract
The utility model discloses a crimple formula steel bar connection connects, it includes sleeve, variable cross section bolt, the spacing guide dog of reinforcing bar axial. Wherein the sleeve is the opening that both ends set up certain length screw thread respectively, and both ends screw thread opposite direction, inside through the coarse sleeve of handling, the variable cross section bolt is an internal cone type and takes the screwed bolt, and the both sides opening part outside the outer sleeve is twisted to the variable cross section bolt, the length of going deep into of the inside reinforcing bar of sleeve can be guaranteed to the spacing guide dog of reinforcing bar axial. Its advantage lies in: through using the connection between variable cross section bolt and the sleeve both ends, shrink sleeve cross -section makes the cheng reliable frictional connection of the inside mat surface in sleeve both ends and bending schedule shape of face, then can connect convenience high efficiency, firm in connection to two joints with the spanner.
Description
Technical field
The utility model discloses a kind of shrinking type steel bar connector.
Background technology
Along with China's modernization of architecture and the quickening of industrialization process, steel reinforced concrete assembling structure and high level, large-span frame xoncrete structure are constantly popularized, bar connecting has become one of key technology of structure design and construction.Shrinking type steel bar connector proposes a kind of new mechanical joining methods, has the advantages such as easy and simple to handle, quality of connection is good, develops more advanced and practical steel concrete supporting part imperative.
Utility model content
1. to solve the technical problem that
In order to solve technical problem, this utility model provides a kind of shrinking type steel bar connector.Can effectively by bar connecting and be positioned sleeve inner, make two ends anchor bar in sleeve distribution of lengths uniformly, be connected firmly, it is ensured that bar connecting reliability.
2. technical scheme
The technical scheme in the invention for solving the technical problem is as follows: a kind of shrinking type steel bar connector, including sleeve, variable cross-section bolt, reinforcing bar axial limiting guide stopper.Described sleeve is opening and the two ends hand of spiral sleeve through coarse process contrary, internal that both sides arrange certain length screw thread；Variable cross-section bolt is a pair screwed bolt of internal cone type, and variable cross-section bolt is screwed at the outer both ends open of outer sleeve；What reinforcing bar axial limiting guide stopper can ensure that sleeve inner reinforcing bar gos deep into length, it is to avoid built-in length is unreasonable.Sleeve lining, through coarse process, tightens sleeve two ends, contracted section by variable cross-section bolt, and sleeve both ends open fully wraps up reinforcing bar and produces powerful bond stress, it is ensured that two ends anchor bar is firmly attached in sleeve, it is ensured that bar connecting reliability.
3. beneficial effect
The beneficial effects of the utility model there is provided a kind of shrinking type steel bar connector, is effectively connected with deformation bolt internal whorl by cartridge exterior that the extruding force of generation makes sleeve both ends open hold splice, internal limit configuration makes the length of two ends anchor bar and stress is more reasonable, the coarse process of sleeve inner is the most all of value to reinforcing bar connection.

Detailed description of the invention
With reference to the accompanying drawings, in conjunction with the embodiments, the shrinking type steel bar connector provided this utility model is described in detail.Referring to the drawings, the shrinking type steel bar connector of the present embodiment, it includes sleeve 1, variable cross-section bolt 2.Sleeve 1 includes reinforcing bar axial limiting guide stopper 3, sleeve both ends open 4, and sleeve both ends open 4 respectively opens four uiform section gaps, the internal matsurface of sleeve 1, forms four circular arc sleeve-shaped outer surfaces and has threaded opening；Variable cross-section bolt 2 is a pair internal cone type screwed variable cross-section bolt；What reinforcing bar axial limiting guide stopper can reasonably ensure sleeve inner reinforcing bar gos deep into length.
Variable cross-section bolt 2 is screwed at the both ends open of sleeve 1, uses screw thread to spin.Reinforcing bar 5 stretches into the aperture at sleeve 1 two ends, the end making reinforcing bar 5 enters at the reinforcing bar axial limiting guide stopper 3 within sleeve 1, the built-in length of two end bars is ensured with this, then variable cross-section bolt 2 is screwed, now the two ends of sleeve 1 are shunk and are compressed reinforcing bar, reinforcing bar 5 is fastenedly connected, the frictional force between matsurface and reinforcing bar 5 inside sleeve so that connect and more fasten.Can be according to practical situation needs, the degree of depth of turn both sides nut, it is only necessary to manually close can complete and be connected firmly with hand-screw, it is the most convenient to use.
Above-described this utility model embodiment, is not intended that the restriction to this utility model protection domain.Any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in claims of the present utility model.
