Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for controlling the pouring center of an anchor pipe. Background Art

[0002] "Anchor pipe pouring" usually refers to embedding anchor pipes or anchor bars into concrete structures and fixing them by pouring concrete. This technology is often used in the construction of buildings, bridges and other concrete structures to ensure the stable connection and force transmission of components. When pouring anchor pipes, it is necessary to pay attention to factors such as the pouring method of concrete, the selection of pouring materials and the curing time to ensure a firm connection between the anchor pipe and the concrete structure.

[0003] When pouring the anchor pipe, it is necessary to ensure that the anchor pipe is placed in the center of the upper port of the anchor hole as much as possible; however, in actual construction, construction workers usually control the upper end of the anchor pipe by hand, and try to control the anchor pipe to be located in the center of the anchor hole based on experience. The accuracy of this center control method is limited. Improper operation may even cause the lower end of the anchor pipe to stick to the side wall of the anchor hole, which greatly affects the strength and tensile strength of the concrete structure after pouring, causing safety hazards. Utility Model Content

[0006] Preferably, the support frame includes a plurality of support rings whose sizes gradually decrease from top to bottom, and the support rings are fixedly connected to each other through support members, thereby increasing the strength of the support frame and ensuring that the device will not be deformed during use to affect the accuracy of the device.

[0007] Furthermore, the support member is N steel bars or steel pipes, and the steel bars or steel pipes are welded between the support rings, and N is greater than or equal to 3. By welding multiple steel bars or steel pipes, it is easy to control the uniformity of the support frame, ensure that the axis of the support frame is placed at the center of the lower limit ring, and is more convenient to use.

[0008] Furthermore, the spacings between the plurality of support rings are the same, and the steel bars or steel pipes are evenly distributed between the support rings, which can ensure that the structural strength of the entire support frame is uniform and not prone to deformation.

[0009] Furthermore, the device also includes an upper limiting platform, wherein a limiting hole is provided in the middle of the upper limiting platform, and the limiting hole is coaxial with the lower limiting ring and has the same inner diameter. The opening of the upper limiting platform is coaxial with the lower limiting ring and has the same inner diameter, thereby ensuring that the anchoring pipe can remain in a vertical state until the bottom of the anchoring hole when placed.

[0010] Furthermore, the upper limit platform is fixed to the inside of the support frame by welding three steel bars, and the three steel bars are evenly distributed on the same support ring. The upper limit platform is fixed to the inside of the support frame by welding three steel bars, which can ensure that the upper limit platform structure is stable and not prone to deflection.

[0011] Furthermore, one or more level bubbles are provided on the upper limit platform, and the level bubbles can be provided to enable the support frame to be placed in a more accurate horizontal position.

[0012] The beneficial effects of the utility model are as follows: the conical support frame of the device is inserted into the upper port of the anchor hole, and the conical support frame is controlled to be in a horizontal state at the upper port of the anchor hole through the horizontal bubble. The upper limit platform and the lower limit ring in the support frame are coaxial with the anchor hole, so that the anchor pipe can be accurately placed in the center position of the anchor hole through a straight line between two points, thereby ensuring the strength of the concrete after pouring; the device has a simple structure and is easy to use.

[0019] Example 1: See Figure 1-5, a device for controlling the casting center degree of an anchor pipe, the device is placed at the upper end of an anchor hole, and is characterized in that the device includes a support frame and a lower limiting ring, the support frame is overall conical, and the conical support frame can be used for all anchor holes that are not larger than the size of the support frame, thereby increasing the adaptability of the device. The lower limiting ring is placed at the bottom center of the support frame and remains coaxial with the support frame; the edge of the upper end of the anchor hole contacts the side wall of the support frame; the inner diameter of the lower limiting ring matches the outer diameter of the anchor pipe. When placing the anchor pipe, it passes through the middle of the lower limiting ring, which can ensure the center degree of placement to a certain extent.

[0020] The support frame includes a plurality of support rings whose sizes gradually decrease from top to bottom, and the support rings are fixedly connected to each other through support members, thereby increasing the strength of the support frame and ensuring that the device will not be deformed during use to affect the accuracy of the device.

[0021] The support member is N steel bars or steel pipes, which are welded between the support rings, and N is greater than or equal to 3. By welding multiple steel bars or steel pipes, it is easy to control the uniformity of the support frame, ensure that the axis of the support frame is placed at the center of the lower limit ring, and is more convenient to use.

[0022] The spacing between the support rings is the same, and the steel bars or steel pipes are evenly distributed between the support rings, which can ensure that the structural strength of the entire support frame is uniform and not prone to deformation.

[0023] The device also includes an upper limiting platform, wherein a limiting hole is provided in the middle of the upper limiting platform, and the limiting hole is coaxial with the lower limiting ring and has the same inner diameter. The opening of the upper limiting platform is coaxial with the lower limiting ring and has the same inner diameter, which ensures that the anchoring pipe can remain in a vertical state until the bottom of the anchoring hole when placed.

[0024] The upper limit platform is fixed to the inside of the support frame by welding three steel bars, and the three steel bars are evenly distributed on the same support ring. The upper limit platform is fixed to the inside of the support frame by welding three steel bars, which can ensure that the upper limit platform structure is stable and not prone to deflection.

[0025] The upper limiting platform is also provided with one or more level bubbles, which can make the support frame more accurately kept in a horizontal position.

[0026] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that, according to the shape and size of the anchoring pipe, corresponding pipe sleeves can be installed on the holes of the upper limit platform and the lower limit ring respectively. When replacing the anchoring hole and the anchoring pipe, the pipe sleeve can be directly replaced as needed, which is more portable and has better versatility.

[0027] Embodiment 3: Embodiment 3 is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that a plurality of leveling bubbles are also installed on the side of the upper limit platform; the horizontal position of the device can be maintained when the anchor pipe is installed on a slope or a wall.
