Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for quickly positioning a reserved hole. Background Art

[0002] During the construction of a house, due to plumbing pipes or ventilation pipes, etc., holes need to be reserved when pouring concrete. Generally, a reserved pipe is fixed in the steel bar. The reserved pipe is against the formwork to seal the bottom surface. The reserved pipe is higher than the concrete surface, which is convenient for later disassembly and avoids the problem of concrete sealing.

[0003] When placing the reserved pipe, it is necessary to position the reserved pipe so that the upper and lower openings are aligned in a multi-story building, or it is necessary to align the position with the equipment installed later in the building (regardless of whether it is a multi-story building or a single-story house). Therefore, the positioning of the reserved pipe is very necessary. The existing opening positioning device generally uses a telescopic rod structure for positioning. However, due to the requirements of different openings in different buildings, reserved pipes of different diameters need to be used to realize the reserved openings. The existing positioning device cannot adapt well to reserved pipes of different diameters, has low applicability, and affects the positioning speed and positioning accuracy. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a quick positioning device for a reserved hole in response to the above-mentioned technical deficiencies, which solves the problem that the existing positioning device cannot adapt well to reserved pipes of different diameters, has low applicability, and affects the positioning speed and positioning accuracy.

[0005] The technical solution adopted by the utility model is to provide a device for quickly locating a reserved hole, comprising:

[0006] There are four positioning plates, the four positioning plates are sequentially connected end to end to form a quadrilateral structure, the adjacent positioning plates are rotatably connected, and the four positioning plates are used to abut against the side surfaces of the reserved pipe;

In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0036] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] like Figure 1-4 As shown, the reserved hole rapid positioning device includes four positioning plates 1, which are connected end to end in sequence to form a quadrilateral structure, and the adjacent positioning plates 1 are rotatably connected, and the four positioning plates 1 are used to abut against the side of the reserved tube; there are several top plates 101, and a top plate 101 is provided on the upper end of the positioning plate 1, and the top plate 101 is used to abut against the upper end of the reserved tube; there are two connecting rods 2, and the two connecting rods 2 are respectively hinged to two adjacent positioning plates 1, and the two connecting rods 2 are arranged in parallel; there are two connecting rods 2 slidingly arranged on the base 3, and the two connecting rods 2 move closer to or away from each other after sliding; there are two positioning rods 4, both of which are arranged on the base 3, and the two positioning rods 4 are arranged perpendicular to each other; there are two positioning seats 401, and each positioning rod 4 is provided with a positioning seat 401 at the end away from the base 3, and the positioning seat 401 is rotatably arranged relative to the base 3 with the positioning rod 4 as the axis.

[0039] During use, when in a multi-story building, taking the pouring of a roof concrete structure of a certain floor as an example, there is a wall steel cage higher than the surface of the roof concrete structure to be poured. The positioning seat 401 is rotated upward and can be abutted against the wall steel cage to be positioned with the wall as the reference plane. The two positioning rods 4 are respectively abutted against two vertical wall steel cages through the positioning seat 401 to realize the positioning of the reserved pipe. The reserved pipe is clamped between the four positioning plates 1. The positioning plates 1 of the quadrilateral structure abut against the four directions of the reserved pipe to achieve centering. The top plate 101 abuts against the upper end of the reserved pipe, and the reserved pipe is higher than the surface of the concrete structure to be poured. The length of the positioning rod 4 can be set according to the drawing, so that multiple openings of the same type can be quickly positioned.

[0040] When there is no wall reinforcement cage higher than the roof concrete structure surface to be poured, the positioning seat 401 is turned downward, and positioning can be performed using the reinforcement cage inside the concrete structure surface to be poured as the reference plane. Note that pouring is not performed at this time. After positioning is completed, the positioning device is removed before pouring.

[0041] The top plate 101 can be perpendicular to the positioning plate 1, and the top plate 101 abuts against the upper end of the reserved tube, which can support and position the height position of the positioning plate 1, and at the same time more stably fix the reserved tube. The number of top plates 101 can be two, and the two top plates 101 can be respectively set on the two positioning plates 1, or a top plate 101 can be set on each positioning plate 1.

[0042] The positioning plates 1 are connected in a rotating manner. After abutting against the outer wall of the reserved tube, the positioning plates 1 can be positioned relative to each other by hand-held, rotating friction resistance, or other existing methods. The four positioning plates 1 are of equal length and can form a diamond shape.

[0043] The positioning seat 401 rotates relative to the base 3 and is set to rotate around the axis of the positioning rod 4. The end of the positioning seat 401 can be rotatably connected to the end of the positioning rod 4, or the end of the positioning plate 1 can be fixedly connected to the end of the positioning rod 4, and the positioning rod 4 is rotatably connected to the base 3.

[0044] Furthermore, the positioning rod 4 is a telescopic rod, and the positioning seat 401 moves relative to the base 3 in a direction parallel to the axis of the positioning rod 4 .

[0045] When in use, the positioning rod 4 can adjust the positioning distance by telescoping, and the end of the positioning rod 4 is plugged into the socket 301, which can be fixed or rotatable, and can be selected in accordance with the setting form of the positioning seat 401. The positioning rod 4 adopts a telescopic rod structure that can be telescopic and fixed in length.

[0046] Furthermore, the base 3 has a socket 301 , and the end of the positioning rod 4 is plugged into the socket 301 .

[0047] When in use, the positioning rod 4 is plugged into the base 3 for easy assembly and disassembly. The base 3 can be provided with sockets 301 on the rear side and the right side, respectively. The axes of the two sockets 301 are perpendicular to each other, and the positioning rods 4 are parallel to the base 3.

[0048] Furthermore, the positioning seat 401 has a plurality of threading holes 4011 .

[0049] During use, the wire insertion holes on the positioning seat 401 can be divided into two rows, through which steel wires can be passed, facilitating the fixed connection between the positioning seat 401 and the wall reinforcement cage. When positioning the reserved pipe, the positioning seat 401 abuts against the wall reinforcement cage to determine the distance. After the reserved pipe is positioned, it is fixedly connected to the surrounding steel bars or the formwork. After positioning is completed, the positioning device can be removed and the concrete can be poured. Of course, the positioning seat 401 can also be fixed until the concrete pouring is completed, and then the positioning device can be removed.

[0050] Furthermore, the base 3 has a sliding groove 302 , and the connecting rod 2 is slidably connected to the sliding groove 302 .

[0051] When in use, the end of the connecting rod 2 can be hinged to the middle of the positioning plate 1, or hinged to the middle of the top plate 101 on the positioning plate 1. The sliding connection between the connecting rod 2 and the base 3 is an existing technology, and a guide restriction can be provided by setting a slide groove 302 to keep the two connecting rods 2 parallel.

[0052] Furthermore, the system further comprises: a first rotating shaft 5, through which two adjacent positioning plates 1, located away from the base 3, are rotatably connected; a second rotating shaft 6, through which two adjacent positioning plates 1, located near the base 3, are rotatably connected; a wire tube 601, disposed on the second rotating shaft 6; a positioning rope 7, one end of which is connected to the first rotating shaft 5 and the other end of which passes through the wire tube and is connected to the base 3. A threaded hole is defined in the upper middle portion of the base 3; a locking bolt 8, which is threadedly connected to the threaded hole and is used to abut the end of the positioning rope 7. Furthermore, a positioning tube 9 is disposed on the base 3 and located between the locking bolt 8 and the wire tube 601. The end of the positioning rope 7 passes through the wire tube 601 and the positioning tube 9 in sequence and abuts the locking bolt 8.

[0053] When in use, there are four rotating shaft connection positions between the four positioning plates 1, one of which is close to the base 3 and opposite to the middle position of the base 3. The positioning plate 1 can be positioned by the positioning rope 7 to keep the positioning plate 1 in contact with the reserved tube. One end of the positioning rope 7 is connected to the first rotating shaft 5, passes through the wire tube 601 on the second rotating shaft 6, and then passes through the positioning tube 9. Finally, it can be wrapped around the threaded portion of the locking bolt 8. By screwing the locking bolt 8 downward, the end of the positioning rope 7 can be squeezed and fixed on the base 3. The two points form a straight line, and the straight line is the shortest. Through the limitation of the wire tube 601 and the positioning tube 9, the straightened positioning rope 7 pulls the first rotating shaft 5 tight against the base 3. At this time, the positioning plate 1 clamps the reserved tube. It can position the reserved tube more stably and is easy to use.
