TH7001A3 - Anchors that can be retracted by external thread rods. - Google Patents

Abstract

DC60 (28/11/54) An external threaded rod tightening anchors consist of an outer structure with a hollow inside, open end. For supporting the insertion of the external threaded rod, the bottom of the outer structure is the bottom tube with an internal threaded pipe to support the extrusion of the external thread for the tension. Provides a smooth center pipe or a through-hole or protruding rod installed on top of the pipe. The transparent bottom puffed out. For helping to attach to the insert support holes While inserting inside the hole An external threaded anchor consists of an outer structure with a hollow inside, an open end. For supporting the insertion of the outer thread rod, the bottom of the outer structure is a bottom pipe with an internal thread to support the extrusion of the outer thread for the retention. Provides a smooth center pipe or a through-hole or protruding rod installed on top of the pipe. The transparent bottom puffed out. For helping to attach to the insert support holes While inserting inside the hole

Claims (7)

1. The tension-shrinkable anchors of the outer threaded rod consist of an outer structure (1) that is structurally outer, with a hollow inside, open-ended (2) where the bottom is the bottom tube (4). For receiving the tension held up The top of the tube (7), the middle tube (7), is a hollow tube inside where the bottom is installed. With the top of the bottom tube (1) and with the top mounted to the bottom of the upper tube (8) for supporting the pass through of the outer thread rod (3), where the top tube (8) will look An inner hollow tube where the bottom will be installed in With the top of the center tube (7) for the through-threaded rods (3) and the top, the upper shoulder (9) is installed, the upper shoulder edge (9) is the shoulder edge. The side on the top of the top tube (8) for supporting the press-in with the upper shoulder (10) of the outer thread rod (3) has a unique feature: On the inside of the bottom pipe (1), an inner threaded tube (5) is inserted to support the rotation with the outer thread (6) of the outer thread (3) to support the rotation. Pull the brace up so that the side of the center tube (7) bulges out while the plug is inserted inside the hole. That supports the insertion 2. Anchors that can be pulled by tension of the outer thread according to claim 1, the middle tube (7) will have a larger parallel, upper diameter Bottom diameter For supporting the expansion of the external threaded rods (3) 3. Anchors that can be retracted by the tension of the outer thread according to claim 1- 2, the middle pipe (7) will have a line through the side of the pipe (11) that is spaced at intervals. Two-line tubs For helping the center tube (7) to shrink more easily. While the inner thread (5) is held upward with the outer thread rod (3) 4. Anchors that can be tensioned by an external threaded rod according to any of the 1-3 claim, the center tube (7) has oblique rods on the side of the tube (12) that are at least intermittent. Two bars This allows the side of the center tube (7) to be more firmly bolted into the supporting hole while the inner thread (5) is pulled up to the Top with outer thread rods (3). 5. Anchors that can be retracted by the tension of the outer thread according to claim 1, the middle tube (7) is a hollow, ventilated tube. For helping side The center tube (7) can be fully secured to the fully supported hole. Thickened while the inner thread (5) is pulled upward with the outer thread rod (3). 6. Anchors that can be pulled by the tension of the outer thread according to claim 5, the middle tube (7) will have at least two intermittent lines through the side of the blister tube (13). For helping the center tube (7) to shrink more easily while the inner thread (5) is pulled upward with the outer thread rod (3). 7. Anchors that can be retracted by the tension of the outer thread according to one of the claims 5-6, the center tube (7) has an oblique rod on the side, the blister tube (14) spaced at intervals. At least two bars This allows the side of the center tube (7) to be more firmly braced into the supported hole while the inner thread (5) is pulled upward by the outer thread rod (3).
