Description
Technical Field
The utility model belongs to the technical field of the construction, in particular to detachable pre-buried anchor assembly.
Background
The steel member is usually welded and fixed to the end of the steel member by using a conventional anchor plate pre-embedded in the building, or the end of the steel member is fixed by using the anchor plate and an expansion screw. These two end fixing means do not present any problems for steel members of permanent construction. However, for a temporary steel structure or a steel structure member for other structural construction, such as an overhanging i-steel for supporting an overhanging frame upright post, the steel structure needs to be removed after the construction task is completed, and the steel structure needs to be cut off by the two end fixing methods, and the cut steel structure cannot be reused, so that manpower and material resources are wasted.
Disclosure of Invention
The utility model aims at solving the problem, a detachable pre-buried anchor assembly that need not the later stage cutting, and repeatedly usable is provided.
Therefore, the technical scheme of the utility model is that: detachable pre-buried anchor assembly, its characterized in that: the embedded part comprises an installing plate and a plurality of fixing parts, wherein the installing plate is provided with a plurality of installing holes, one end of each fixing part is provided with a U-shaped hook, the other end of each fixing part is provided with external threads, and the fixing parts penetrate through the installing holes and are welded and fixed with the installing plate; the interior of the conical nut is provided with an internal thread structure, the small end of the conical nut is fixed with the fixing piece through threads, and the large end of the conical nut is fixed with the outer screw rod through threads.
Preferably, the number of the conical nuts and the outer screw rods is consistent with that of the fixing pieces.
When the embedded part is used, the embedded part, the conical nut and the outer screw rod are assembled, then the embedded part is embedded according to the designed position, and the outer screw rod is left outside; and pouring concrete, welding an anchor plate with a matched opening at the end part of the steel member in advance after the concrete reaches a certain strength, aligning the anchor plate at the end part of the steel member with the outer screw rod before installation, and then installing in place. And finally, screwing the gasket and the nut into the outer screw rod in sequence and screwing the gasket and the nut tightly, and finishing the installation of the steel member. After construction is finished, firstly screwing down the screw cap, then unscrewing the outer screw rod by using an electric wrench, then removing the steel member, and finally unscrewing the conical nut by using the electric wrench; and the holes left by unscrewing the cone nuts are filled by using cement mortar, so that water leakage is prevented. The detached external screw rod and the detached conical nut can be reused.
The utility model discloses divide into pre-buried built-in fitting and the outer screw rod two parts of detachable with pre-buried anchor assembly in the wall body, both are connected through conical nut, can normal use during the connection, and the step of follow-up cutting outer screw rod has been avoided to outer screw rod and conical nut dismantlement that finishes using. And the outer screw rod and the conical nut can be disassembled through the electric wrench, so that the tool is convenient and fast, can be repeatedly used, and reduces the construction cost.

Labeled as: the steel structure comprises an embedded part 1, a mounting plate 11, a mounting hole 111, a fixing part 12, a U-shaped hook 121, a first external thread 122, a conical nut 2, an internal thread structure 21, an external screw rod 3, a steel member 4 and an anchor plate 41.
Detailed Description
See the drawings. The embedded anchoring part comprises an embedded part 1, a conical nut 2 and an outer bolt 3, wherein the embedded part 1 is connected with the outer bolt 3 through the conical nut 2; the embedded part 1 comprises an installation plate 11 and 6 fixing parts 12, wherein the installation plate 11 is provided with 6 installation holes 111, one end of each fixing part 12 is provided with a U-shaped hook 121, the other end of each fixing part 12 is provided with a first external thread 122, and one end of each fixing part 12 with the first external thread penetrates through the installation hole 111 and is welded and fixed with the installation plate 11; the internal thread structure 21 is arranged in the conical nut 2, the small end of the conical nut 2 and one end, with the first external thread, of the fixing piece 12 are fixed through threads, the external screw rod 2 is provided with the second external thread structure, and the large end of the conical nut 2 and the external screw rod 3 are fixed through threads. The number of the conical nuts 2 and the outer screw rods 3 is the same as that of the fixing pieces 12.
When the embedded part is used, the embedded part 1, the conical nut 2 and the outer screw rod 3 are assembled, then the embedded part 1 is embedded according to the designed position, and the outer screw rod 3 is left outside the wall body; and pouring concrete, welding an anchor plate 41 with a matched opening at the end part of the steel member 4 in advance after certain strength is achieved, aligning the anchor plate 41 at the end part of the steel member with the outer screw rod 3 before installation, then installing in place, finally screwing the gasket and the nut into the outer screw rod in sequence and screwing tightly, and completing the installation of the steel member.
As shown in fig. 6 (a) - (d), after the construction is completed, the nut is firstly screwed down, then the outer screw rod 3 is unscrewed by using an electric wrench, then the steel member 4 is removed, and finally the conical nut 2 is unscrewed by using the electric wrench; and the holes left by unscrewing the cone nuts are filled by using cement mortar, so that water leakage is prevented. The detached external screw rod 3 and the detached conical nut 2 can be reused.
