Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a pre-reserved hole construction device for water, electricity and heating installation based on civil engineering. Background Technology

[0002] In the field of civil engineering construction, the accuracy of pre-reserved holes for water, electricity, and heating installations is crucial for subsequent pipeline layout. However, existing technologies generally suffer from two major problems: First, traditional pre-reserved hole devices are prone to displacement due to external forces during concrete pouring, leading to deviations in the position or deformation of the pre-reserved hole, severely affecting construction quality; second, most devices have fixed structures, making it difficult to adapt to the inner walls of outer sleeves of different sizes, limiting their applicability and increasing construction difficulty. These problems not only reduce construction efficiency but may also lead to rework later, increasing costs. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the prior art and provide a pre-reserved hole construction device based on civil engineering for water, electricity and heating installation that can effectively prevent the pre-reserved hole device from shifting during concrete pouring, ensure the accuracy and stability of the pre-reserved hole, is easy to operate, highly adaptable, and can improve construction efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A construction device for pre-reserved holes for water, electricity and heating installation based on civil engineering includes a fixed disc, a central rod fixedly connected to the center of the inner end face of the fixed disc, and a support body fitted on the central rod.

[0006] The outer end face of the fixed disc is provided with at least three recessed grooves, and the recessed grooves are provided with screw holes through which the fixing screws can pass.

[0007] The end of the central rod that connects to the fixed disc is integrally formed with a spline.

[0008] The support body includes a sliding sleeve fitted onto the upper part of the central rod and a fixed sleeve fitted onto the lower part. The upper end of the sliding sleeve has an integrally formed push block, and the push block has connecting ears on both sides. The central hole of the sliding sleeve and the push block is a spline hole that matches the spline, and the sliding sleeve and the push block are slidably connected to the spline. The outer ring of the sliding sleeve and the fixed sleeve has four integrally formed and evenly distributed sliding sleeve connecting seats and fixed sleeve connecting seats. Four support rods made of rubber material are evenly distributed around the periphery of the sliding sleeve and the fixed sleeve. The outer wall surface of the support rod is an arc surface. The support rods are connected to the sliding sleeve and the fixed sleeve respectively through sliding sleeve connecting rods and fixed sleeve connecting rods. The two ends of the sliding sleeve connecting rod are respectively hinged to the sliding sleeve connecting seat and fixedly connected to the support rod. The two ends of the fixed sleeve connecting rod are respectively hinged to the fixed sleeve connecting seat and fixedly connected to the support rod. All four support rods are located below the surface of the fixed disc.

[0009] Two electric push rods are symmetrically installed on the fixed disk along the center of the disk, passing through the fixed disk. The lower ends of the two electric push rods are fixedly connected to the connecting ears on both sides of the push block. A battery that supplies power to the electric push rods is installed inside the fixed disk.

[0010] Preferably, the support rod has a T-shaped cross-section, the outer wall surface of the top plate of the T-shaped rod is an arc-shaped surface, and the sliding sleeve connecting rod and the fixed sleeve connecting rod are connected to the web plate.

[0011] Preferably, the sliding sleeve connecting rods are arranged in pairs, with one end of each pair of sliding sleeve connecting rods clamped and hinged to the sliding sleeve connecting seat, and the other end clamped and fixedly connected to the support rod; the fixed sleeve connecting rods are arranged in pairs, with one end of each pair of fixed sleeve connecting rods clamped and hinged to the fixed sleeve connecting seat, and the other end clamped and fixedly connected to the support rod.

[0012] Preferably, four sinks are evenly distributed on the outer end face of the fixed disc.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through a unique support structure design, four support rods are used to extend outwards. The support rods are made of rubber material, and the arc-shaped structure of their outer wall can fit tightly with the inner wall of the outer sleeve used during construction. This not only improves the friction and support force between the support rod and the outer sleeve, but also effectively avoids displacement during concrete pouring, thereby ensuring the accuracy and stability of the reserved opening.

[0015] 2. The sliding sleeve is driven by an electric actuator to slide along the spline on the central rod, enabling the support rod to automatically open or retract, accommodating outer sleeves of different diameters. Furthermore, a built-in battery in the fixed disc powers the electric actuator, eliminating the need for an external power source. This significantly improves the portability and applicability of this invention on construction sites, simplifies the construction process, and increases construction efficiency.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-3 The pre-reserved hole construction device for water, electricity and heating installation based on civil engineering described in this utility model includes a fixed disc 1, a central rod 4 fixedly connected to the center of the inner end face of the fixed disc, and a support body 6 fitted on the central rod.

[0025] The outer end face of the fixed disc 1 is provided with at least three recessed grooves 2. In this embodiment, four recessed grooves are provided. The recessed grooves are provided with screw holes through which the fixing screws 3 can pass.

[0026] The end of the central rod 4 that connects to the fixed disc has a spline 5 integrally formed.

[0027] The support body 6 includes a sliding sleeve 62 fitted onto the upper part of the central rod 4 and a fixed sleeve 61 fitted onto the lower part. The upper end of the sliding sleeve 62 has an integrally formed push block 63, and both sides of the push block have connecting ears 64. The central hole of the sliding sleeve and the push block is a spline hole (an inner hole with a spline groove) that mates with the spline 5, and the sliding sleeve and the push block are slidably connected to the spline. The outer rings of the sliding sleeve and the fixed sleeve each have four integrally formed, evenly distributed sliding sleeve connecting seats 621 and fixed sleeve connecting seats 611. As shown in the image, [the image is missing here, likely due to an error in the original text]. Figure 3 The support assembly 66 is shown. The support assembly includes a support rod 664 made of rubber, a sliding sleeve connecting rod 663, and a fixed sleeve connecting rod 662. Four sets of support assemblies are evenly distributed around the periphery of the sliding sleeve and the fixed sleeve. The outer wall surface of the support rod 664 is arc-shaped. The support rod is connected to the sliding sleeve and the fixed sleeve respectively via the sliding sleeve connecting rod 663 and the fixed sleeve connecting rod 662. One end of the sliding sleeve connecting rod 663 is hinged to the sliding sleeve connecting seat 621, and the other end is fixedly connected to the support rod 664. One end of the fixed sleeve connecting rod 662 is hinged to the fixed sleeve connecting seat 611, and the other end is fixedly connected to the support rod 664. All four support rods are located below the surface of the fixed disk, and the diameter of the annular ring formed by the four support rods cannot exceed the diameter of the fixed disk.

[0028] Two electric push rods 7 are symmetrically installed on the fixed disc 1 along the center of the disc, passing through the fixed disc. The lower ends of the two electric push rods are fixedly connected to the connecting ears 64 on both sides of the push block. A battery for powering the electric push rods is installed inside the fixed disc. No additional power supply is required, which greatly improves the portability and applicability of this utility model at the construction site, simplifies the construction operation process, and improves the construction efficiency.

[0029] As a preferred design, the support rod 664 is a T-shaped rod with an arc-shaped outer wall surface at the top plate. The sliding sleeve connecting rod 663 and the fixed sleeve connecting rod 662 are connected to the web plate 661 of the T-shaped rod. The sliding sleeve connecting rods 663 are arranged in pairs, with one end of each pair clamped and hinged to the sliding sleeve connecting seat 621, and the other end clamped and fixedly connected to the support rod 664. The fixed sleeve connecting rods 662 are also arranged in pairs, with one end of each pair clamped and hinged to the fixed sleeve connecting seat 611, and the other end clamped and fixedly connected to the support rod 664.

[0030] The electric push rod 7 drives the push block and sliding sleeve of the support body 6 to slide along the spline 5, realizing the automatic outward opening or inward retraction of the four support rods 664 to adapt to the different diameter outer sleeves 8 used for auxiliary construction. At the same time, the support rods are made of rubber material, and the arc structure of its outer wall can fit tightly with the inner wall of the outer sleeve 8, which not only improves the friction and support force between the support rods and the outer sleeve, but also effectively avoids displacement during concrete pouring, thereby ensuring the accuracy and stability of the reserved opening.

[0031] The method of using this utility model is as follows: Figure 4 As shown, firstly, the supporting body 6 of this utility model is placed inside the outer sleeve 8. The two ends of the outer sleeve 8 are fitted with a first construction wall plate 9 and a second construction wall plate 10. Then, two electric push rods 7 are simultaneously activated, pushing the connecting lugs 64 fixedly connected to them. This causes the push block 63 to slide along the spline 5 on the central rod 4. The movement of the push block 63 causes the sliding sleeve 62 to move synchronously. The spline hole of the sliding sleeve 62 is slidably connected to the spline 5, ensuring smooth sliding without rotation. During the movement of the sliding sleeve 62, the supporting rod 664 is pulled by the sliding sleeve connecting rod 663. The supporting rod 664 then applies force to the fixed sleeve connecting seat 611 through the fixed sleeve connecting rod 662, causing the supporting rod 664 to open outwards and tightly fit against the inner wall of the outer sleeve 8, forming a stable supporting force. Then, the fixing disc 1 is fixedly connected to the first construction wall plate 9 by the fixing screws 3, further improving the stability of the entire device and preventing displacement during concrete pouring. After completing the above operations, pour concrete, and remove the device after the concrete has solidified, leaving a precise pre-reserved opening.

[0032] This utility model has a stable structure, flexible adjustment, is easy to disassemble and maintain, is convenient to use, and is highly practical.

[0033] The foregoing has shown and described the main structural features and basic principles of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes to equivalent technical means fall within the protection scope of this utility model.
