Description
Technical Field
The utility model relates to an crab-bolt especially relates to a heat preservation crab-bolt structure.
Background
The traditional heat-preservation anchor bolt structure consists of an anchor bolt body and a metal nail, wherein the bolt body is expanded by rotating the metal nail, so that the bolt body extrudes the hole wall of a drilled hole to generate the action of expansion force. When the structure is used, a cold bridge is easily formed at the metal nail, so that the structure is not beneficial to building energy conservation and heat preservation, and a large amount of metal nails are also not beneficial to material conservation.
Disclosure of Invention
An object of the utility model is to overcome prior art's is not enough, provides a construction simple process, installation convenient operation, can effectively avoid appearing the heat preservation crab-bolt device of not only energy-conservation but also material-saving of cold bridge again. After the traditional heat preservation crab-bolt used, the metal peg position formed cold bridge easily, was unfavorable for building energy-conservation heat preservation, and the use of metal peg in a large number also is unfavorable for material saving moreover.
The utility model discloses a heat preservation crab-bolt structure, have the crab-bolt body of cavity including the centre, the crab-bolt body including set up at the anterior fusiformis structure and connect the tie rod at fusiformis structure tail end the inner wall of the cavity of tie rod on be provided with the internal thread. Mortise and tenon structures are respectively arranged at the upper part and the lower part of the inner wall of the cavity of the fusiform structure, wherein the mortise and tenon structure at the upper part and the mortise and tenon structure at the lower part of the fusiform structure are mutually inserted and matched;
the anterior threaded connection of the cavity of cock stem have the metal peg core, the afterbody of the cavity of cock stem and the anterior screw thread pole section threaded connection of a metal peg cap the head of metal peg cap radially be equipped with the driving lever along the metal peg cap, one section border of the afterbody of metal peg core outwards outstanding formation crotch, the metal peg cap can make the front end of metal peg cap insert the afterbody cavity of metal peg core and the driving lever card is gone into the crotch and is rotated in order to drive the metal peg core through forward rotation for the metal peg core inserts and rises fusiformis structure between the mortise and tenon structure of fusiformis structure upper portion and the mortise and tenon structure of lower part and open, perhaps the metal peg cap can make the front end of metal peg cap break away from the afterbody cavity of metal peg core and throw off with the crotch in order to expose the cock stem cavity of metal peg core afterbody rear side through the reverse rotation.
The utility model has the advantages that: the metal nail is broken to form a metal nail cap and a metal nail core, after the wall is drilled, a heat-preservation anchor bolt body and the metal nail core are placed, a clamping head is arranged at the head of the metal nail cap, a clamping groove is formed in the tail of the metal nail core, the clamping head at the head of the metal nail cap is clamped into the clamping groove in the tail of the metal nail core through forward rotation of the metal nail cap and drives the metal nail core to rotate, the nail core is conveyed to the bottom of the bolt body to expand the bolt body, then the metal nail cap is rotated reversely, the clamping head at the head of the metal nail cap slides out of the clamping groove in the tail of the metal nail core to be broken, the metal nail cap is drawn out and can be repeatedly used; and finally, the bolt cap is installed, and the bolt cap and the nail core form a section of cavity, so that the metal nail which originally forms the cold bridge forms a perfect partition, and the cold bridge is effectively avoided.

Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings.
As shown in the attached drawings, the utility model discloses a heat preservation crab-bolt structure, including the crab-bolt body 1 that has the cavity in the middle of having, crab-bolt body 1 including set up at anterior fusiformis structure and connect the tie rod at fusiformis structure tail end the inner wall of the cavity of tie rod on be provided with the internal thread. Mortise and tenon structures are respectively arranged on the upper part and the lower part of the inner wall of the cavity of the fusiform structure, wherein the mortise and tenon structure on the upper part and the mortise and tenon structure on the lower part of the fusiform structure are mutually spliced and matched.
The front part of the cavity of the bolt rod is in threaded connection with a metal nail core 2, the tail part of the cavity of the bolt rod is in threaded connection with a threaded rod section at the front part of a metal nail cap 3, a deflector rod is arranged at the head of the metal nail cap 3 along the radial direction of the metal nail cap 3, a section of edge at the tail of the metal nail core 2 protrudes outwards to form a hook, the metal nail cap 3 can enable the front end of the metal nail cap to be inserted into the tail cavity of the metal nail core 2 through forward rotation, the deflector rod is clamped into the hook to drive the metal nail core 2 to rotate, so that the metal nail core 2 is inserted between the mortise and tenon structure at the upper part and the mortise and tenon structure at the lower part of the fusiform structure to expand the fusiform structure, or the metal nail cap 3 can make the front end of the metal nail cap separate from the tail cavity of the metal nail core 2 through reverse rotation, and the deflector rod is separated from the hook to expose the bolt rod cavity at the rear side of the tail of the metal nail core 2.
The metal peg 2 rotates so that the hole wall is pressed by the bolt body, generating an expansive force. When the metal nail cap 3 rotates reversely, the deflector rod is separated from the hook, the metal nail cap 3 is drawn out, and finally the protective cap 4 is covered.
Referring to fig. 4, the method of use of the present structure is as follows:
paste heated board 7 on reinforced concrete wall 6, then drill, lay anchor bolt body 1, send into metal peg core 2 through metal peg cap 3 normal rotation and strut the anchor bolt between the mortise and tenon structure on fusiformis structure upper portion and the mortise and tenon structure of lower part, then the metal peg cap 3 is taken out in the counter-rotation, and circulated repetitious usage, then add the helmet 4 at the tip of the cavity of tie rod, closed cavity 5 has been formed between helmet 4 and metal peg core 2, form perfect wall to the traditional metal peg of inside and outside UNICOM, effectively avoided the appearance of cold bridge when material saving, energy-conserving effect has been reached.
