Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a rapid installation device for floor expansion screws used in construction engineering. Background Art

[0002] Expansion screws are a type of fastener that is easy to install and has a wide range of applications. During the installation and decoration of construction projects, when working on the decoration hangers and electromechanical installation hangers, construction workers have to stand on a mobile operating platform or a "ladder" and operate the installation of expansion screws.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 and 2As shown, the present embodiment discloses a rapid installation device for floor expansion screws for construction engineering, comprising a force transmission hollow rod 1, a hexagonal sleeve head 2, a hand-held hollow rod 3 and a through-rod 5. Specifically, a detachable hexagonal sleeve head 2 is provided at the upper end of the force transmission hollow rod 1, a detachable hand-held hollow rod 3 is provided at the lower end of the force transmission hollow rod 1, a handle bar 4 is fixed on the hand-held hollow rod 3, the hand-held hollow rod 3 and the handle bar 4 are arranged in a cross shape, and rubber handles 9 are provided at both ends of the handle bar 4.

[0024] The through-rod 5 passes through the hand-held hollow rod 3, the force-transmitting hollow rod 1, and the hexagonal socket head 2 from bottom to top. A friction damping member 6 is provided between the through-rod 5, the hand-held hollow rod 3, and the force-transmitting hollow rod 1. When the through-rod 5 penetrates into the force-transmitting hollow rod 1, the friction damping member 6 prevents it from falling. A through-rod hammer 7 is fixed at the upper end of the through-rod 5, and the through-rod hammer 7 can be made of chrome-molybdenum steel. A hammer handle 8 is fixed at the lower end of the through-rod 5.

[0025] During operation, select a matching hexagonal socket head 2 according to the specifications of the installed expansion screw or hanger nut, and determine the appropriate length of the force-transmitting hollow rod 1 according to the height of the operator and the floor height. The hexagonal socket head 2, the force-transmitting hollow rod 1 and the hand-held hollow rod 3 are connected and tightened in sequence, and the through-rod 5 is inserted into the hand-held hollow rod 3 from bottom to top in sequence. The through-rod 5 is prevented from falling off by the friction damping member 6. Put the nut end of the expansion screw into the hexagonal socket head 2, align it with the target hole that has been drilled, hold the hammer handle 8 and tap it upward several times to embed the expansion screw in the hole until the washer is flush with the roof surface; keep the tool in the current state, then hold the handle rod 4 with both hands, slowly apply force in the clockwise direction, tighten the expansion screw nut, and ensure that it is firmly installed with the concrete floor after expansion. Finally, remove the installation tool, check the firmness of the expansion screw installation, and carry out the next installation operation.

[0026] In this embodiment, the force transmission hollow rod 1 is fastened to the handheld hollow rod 3 and the hexagonal socket head 2 through threaded connection. As a structure that can realize the above-mentioned threaded connection, Figure 3 As shown, the outer wall of the lower end of the hexagonal socket head 2 and the outer wall of the lower end of the force-transmitting hollow rod 1 are both provided with external threads 10; at the same time, the inner wall of the upper end of the handheld hollow rod 3 and the inner wall of the upper end of the force-transmitting hollow rod 1 are both provided with internal threads 11.

[0027] In this embodiment, Figure 4 As shown, the friction damping member 6 is a rubber ring, there are multiple rubber rings, and they are fixed on the through-rod 5 at intervals, and the outer ring of the rubber ring elastically presses against the inner wall of the hand-held hollow rod 3 and the force-transmitting hollow rod 1.

[0028] In this embodiment, Figure 5As shown, a spring clamping bead 201 is arranged on the inner wall of the upper end of the hexagonal socket head 2. After the nut end of the expansion screw is placed into the hexagonal socket head 2, the spring clamping bead 201 can squeeze and fix the expansion screw.
