Abstract
The utility model relates to a fast butt anchoring bolt used for installing concrete, particularly an installing bolt for a concrete basal plane and especially a bolt which can realize fast anchoring and flat head installation. One end of a lock sleeve is provided with an inner screw hole which can tightly screw a standard bolt and the other end is provided with a cross slot along the axial direction. A tip of a cast conical locking head is wedged into a slot opening of the cross slot. When the utility model is used, an installation site is punched with a hole, the cast conical locking head is inserted into the cross slot of the lock sleeve, the lock sleeve is inserted into the bottom of a punched installing hole, and the bottom of the inner screw hole is hammered, which causes the cast conical locking head to be tightly wedged in the cross slot. Because of the conical wedge effect of the conical head, the lower part of the lock sleeve is spread and is squeezed and pressed with the wall of an anchoring hole so that the lock sleeve is firmly fixed in the anchoring hole. The utility model can be tightly screwed and fixed in a common screw hole by screwing the standard bolt 1 and the surface of the anchoring hole is a plane surface after a screw rod is screwed out of the installing hole. The installing surface can be kept as a plane. The utility model has the advantages of simple structure and fast and convenient installation and is suitable for various temperatures and moisture.
Description
Technical field
The utility model relates to a kind of construction bolt that is used for concrete surface, especially can realize quick anchoring and can realize the bolt that tack is installed.
Background technique
The metope of concrete structure install or fixedly article usually need to use construction bolt, for there not being pre-buried situation, common chemical crab-bolt and telescopic EXPANSION ANCHOR BOLTS all adopt the bolt body of rod are fixed on concrete surface at present, install and fix mode with nut then.Because screw rod is to be fixed on the metope, the screw rod wall part of emerging is fixed, this situation to the parallel mobile installation of need is made troubles, to the object that installs and fixes temporarily, after material installed is taken away, the body of rod that exposes not only outward appearance is attractive in appearance inadequately, and brings a lot of inconvenience can for the use in later stage.So need to remove with the body of rod that manually will expose in addition toward contact when practical.And also there are shortcomings such as chemical bonding condensation of materials stand-by period length and non-refractory in chemical anchor bolts.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned concrete surface construction bolt, and aiming to provide a kind of bolt front fixing surface that can keep is the plane, and can realize the tack quick mounting concrete anchor bolt of quick mounting anchoring.
The implementation of the utility model purpose is, tack quick mounting concrete anchor bolt, and lock tube 2 one ends have the inner bolt hole 6 that screws standard bolt 1, and the other end has cross recess 3 vertically, the notch of the tip wedging cross recess 3 of casting taper tapered end 4.
The utility model is compared with prior art, and bolt is not to be fixed in the concrete, but with the lock tube predetermined fixed in concrete.The locking of lock tube mainly is by the wedging expansion of axial cross recess and tapered end cross conical head and be fixed in the concrete.Because the lock sleeve upper end is provided with the locking screw, standard bolt 1 screws at the locking screw and gets final product.Because what lock tube adopted is metal wedging mechanical self-latching, can lock so install back standard bolt 1, realize quick anchoring.Inorganic or the organic binding material of can annotating in anchor hole before the lock sleeve is installed in case of necessity,, and is made anchoring effect more safe and effective in order to the filling hole internal pore.
Installation screw rod of the present utility model need not be fixed on to be installed on the matrix, installation surface can remain the plane, convenient requirement in particular cases to installing, and lock sleeve has adopted voussoir locking principle and has been aided with binding material, realize the quick anchoring installation, and can adapt to all temps and damp condition.The utility model is simple in structure, can install and fix with general tool, and is easy to use.

Fig. 3 is not for adorning the utility model structural representation of standard bolt
Embodiment
Constitute by standard bolt 1, lock tube 2 and casting taper tapered end 4 with reference to Fig. 2,3 the utility model.Standard bolt is the Steel Bolt of selecting for use according to installation requirement.Lock tube 2 usefulness diameters are made greater than the round steel in screw rod bar footpath, and casting taper tapered end cylinder iron is cast as.The length of lock tube 2 is 10 ± 0.1 times of master screw 1 external diameter.
Lock tube 2 one ends have the lock tube inner bolt hole 6 that screws standard bolt 1, are used for screwing standard bolt 1, and the other end has cross recess 3 vertically, are used for wedging casting taper tapered end 4.Cross recess 3 groove widths 1 ± 0.1mm, flute length 30 ± 2mm.Casting taper tapered end 4 conehead top width are not more than 1mm.
The utility model using method is as follows: with concrete electric hammer drill straight hole, drilling depth is that the length of lock tube 2 adds 10mm in the installation position, and bore diameter is that the external diameter of lock tube 2 adds 1-2mm; To cast taper tapered end 4 then inserts in the cross recess 3 of lock tube 2, and the lock tube 2 that will have tapered end inserts at the bottom of the good mounting hole of brill, with the bottom of diameter less than the round steel hammering inner bolt hole 6 of lock tube inner bolt hole 6 internal diameters, the conical head that makes casting taper tapered end 4 wedge gradually advances in the cross recess, and wedging in cross recess.Because the awl wedge effect of conical head, the bottom of lock tube 2 is also strutted and is pushed with the anchoring hole wall in conehead wedging process, thereby lock tube 2 is fixed in anchor hole firmly, forms state shown in Figure 1.Screwing on standard bolt 1 just can be tightened in common screw.After the standard bolt that screws screwed out from mounting hole, the anchor hole surface was the plane.
For need long-term standard bolt that keeps in mounting hole, can before the lock tube 2 that will have tapered end inserts mounting hole, in mounting hole, inject the organic or inorganic pouring material, and then carry out later installation procedure.
