Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a flexible metal conduit laying device. Background Technology

[0002] Flexible metal conduits are protective pipes with an outer layer of hot-dip galvanized steel strip and an inner wall coated with a special insulating resin layer. These pipes offer good strength and insulation, can be pre-embedded in reinforced concrete, and can be shaped as needed, overcoming the weaknesses of steel pipes, flexible metal hoses, and PVC pipes in certain applications, such as those requiring bending, earthquake resistance, and corrosion resistance. However, a problem arises when using flexible metal conduits for pre-embedding: the conduit roll is placed directly on the truss floor slab, and during the dragging and laying of the bent conduit, the bottom of the roll repeatedly contacts the reinforcing steel, sometimes causing damage. Therefore, a flexible metal conduit laying device is needed. Utility Model Content

[0003] The purpose of this utility model is to provide a flexible metal conduit laying device for construction on truss floor decks.

[0004] This utility model is achieved through the following measures: a flexible metal conduit laying device, characterized in that it includes a fixing block, a column vertically arranged on the fixing block, a rotating frame rotatably arranged on the column, horizontal insert rods symmetrically arranged on both sides of the fixing block, an outer sleeve rod inserted into the horizontal insert rod, a connecting rod fixedly arranged at the outer end of the outer sleeve rod, a support leg arranged at both ends of the connecting rod, a slot for inserting a reinforcing bar arranged on the outer side of the support leg, and a screw that presses against the horizontal insert rod is threadedly connected to the outer sleeve rod; The rotating frame includes a rotating block rotatably mounted on the column. At least three extension rods are evenly distributed circumferentially on the outer wall of the rotating block. Vertical inner and outer limit rods are respectively provided above the inner and outer ends of the extension rods. The upper end of the column is provided with a pipe ring.

[0005] Furthermore, a support plate is fixedly installed on the column and below the rotating block, and the rotating block is rotatably mounted on the column via a bearing.

[0006] Furthermore, a flexible metal conduit roll is placed between the inner and outer limiting rods.

[0007] Furthermore, a support block is fixedly installed on the lower outer wall of the support leg, and a screw is threadedly connected to the support block, with a support plate fixedly installed at the lower end of the screw.

[0008] Furthermore, several slots are evenly distributed vertically, typically three. The opening of each slot is generally slightly larger than the outer diameter of the reinforcing bar.

[0009] Furthermore, a sliding sleeve is fixedly provided at the lower end of the inner limiting rod. The sliding sleeve is slidably mounted on the extension rod, and a screw is threadedly connected to the sliding sleeve and presses against the extension rod. Loosening the screw can change the position of the inner limiting rod, thereby adjusting the distance between the inner and outer limiting rods.

[0010] Furthermore, adjacent extension rods are connected by a reinforcing rod.

[0011] Furthermore, the four reinforcing rods form a rectangular frame and the extension rod is located at the connection point of two adjacent reinforcing rods.

[0012] How to use: Based on the distance between two adjacent steel bars at the construction site, adjust the distance between the two support legs and make the slots on the support legs engage with the corresponding steel bars. At this time, the positioning of the flexible metal conduit laying device is achieved through the limiting of the steel bars and the cooperation of the support legs. Place the flexible metal conduit roll between the inner and outer limit rods, and adjust the distance between the inner and outer limit rods according to the size of the roll.

[0013] The first end of the conduit is passed through the pipe-passing ring, and the conduit that has passed through the pipe-passing ring is pulled manually. During the pulling process, the rotating frame rotates to keep the conduit extending out of the pipe-passing ring, thereby assisting the manual laying of the conduit and minimizing the connection between the bottom of the conduit roll and the reinforcing bar.

[0014] The beneficial effects of the technical solution provided by this utility model embodiment are: assisting manual laying of flexible metal conduits on truss floor decks and minimizing contact between the bottom of the conduit roll and the reinforcing steel. Attached Figure Description
