An embedded steel plate installation device and installation method

Abstract

This invention relates to an installation device and method for embedded steel plates. The device includes a template, a first fastener, a fastening mechanism, an adjustment mechanism, and a second fastener. The method utilizes a first groove on the template to install the first fastener. The cooperation of two first fasteners restricts the steel plate to be fixed on the template. The adjustment mechanism installed on the second groove adjusts the position of the template and fixes it by connecting it to the scaffolding. After aligning the embedded steel plate with the elevation, concrete can be poured. If the position of the embedded steel plate changes during pouring, the fastening mechanism, in conjunction with the first fastener and the adjustment mechanism, adjusts the position of the embedded steel plate to effectively ensure the installation elevation and positional accuracy of the embedded steel plate. After construction is completed, the template can be removed and reused by loosening the fastening mechanism and the adjustment mechanism. The first fastener, which is mixed into the concrete like the embedded steel plate, only needs to be ground smooth. The installation process is simple and easy to install and disassemble.

Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a pre-embedded steel plate installation device and installation method. Background Technology

[0002] In the construction of concrete beam and column structures in civil engineering, it is often necessary to embed steel plates during the concrete pouring process to serve as welding points for later steel components, power cable trays, railings, etc. The traditional method for installing and fixing these embedded steel plates involves spot welding or binding the steel plates, which have tie bars, to the structural reinforcing bars after the reinforcement is tied, then erecting the formwork, and finally pouring concrete. Since the formwork is erected after the embedded steel plates are positioned and fixed, inaccurate positioning, insecure fixing, damage from vibration during pouring, and rebar misalignment often cause the embedded steel plates to shift after the concrete is removed from the formwork. This makes it impossible to weld and install the required steel structural components according to the design requirements. Furthermore, the traditional method of using rebar, nails, and precast concrete supports to brace the other side of the formwork to ensure a tight fit between the embedded steel plate and the formwork is problematic. In practice, these symmetrical supports are prone to falling off, making it difficult for the surface to adhere tightly to the formwork during concrete pouring. As a result, the embedded steel plates cannot be exposed on the concrete surface after demolding, requiring manual chiseling to expose them – a time-consuming and labor-intensive process. After the concrete is removed from the embedded steel plates, a height difference exists between the concrete surface and the embedded steel plate surface, making welding between the steel structure and the embedded steel plates difficult. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] Example 1

[0044] Combination Figures 1-5As shown, this embodiment discloses a pre-embedded steel plate installation device, including a template 1, a first fastener 2, a fastening mechanism 3, an adjustment mechanism 4, and a second fastener 5. The template 1 is a rectangular plate structure, with multiple first grooves 6 formed on one end face. Each first groove 6 has two first wing plates 7 on its sidewall, which are respectively disposed on the two sidewalls of the first groove 6, making the cross-sectional shape of the first groove 6 T-shaped. Two second grooves 8 are formed on the other end face of the template 1, with two second wing plates 9 on their sidewall, which are respectively disposed on the two sidewalls of the second groove 8, making the cross-sectional shape of the second groove 8 T-shaped. It is worth noting that the directions of the first grooves 6 and the second grooves 8 are the same. Two third grooves 18 are formed on the other end face of the template 1, and the two third grooves 18 and the two second grooves 8 are arranged perpendicularly and alternately, forming a grid structure. It is easy to understand that the number of first grooves 6, second grooves 8, and third grooves 18 is at least two, and all are an even number.

[0045] Furthermore, this embodiment also has multiple first fasteners 2, which are slidably connected and disposed within the first slide groove 6. In use, if a template 1 only needs to install one embedded steel plate, then only the first fasteners 2 need to be installed in the two first slide grooves 6 corresponding to the side positions of the embedded steel plate. It is worth noting that each first fastener 2 has a first fastening plate 10 and a second fastening plate 11. The first fastening plate 10 is slidably disposed within the first slide groove 6; the second fastening plate 11 is used to fasten with the embedded steel plate.

[0046] Furthermore, in this embodiment, each first fastener 2 is connected to at least one fastening mechanism 3. The fastening mechanism 3 includes a fastening block 12, a fastening rod 13, and a fastening screw block 14. The fastening block 12 is fixedly connected to one end of the fastening rod 13, and the fastening block 12 is disposed between the first fastening plate 10 and the first wing plate 7. A through hole is formed on the first fastening plate 10, and an oblong hole is formed on the template 1. The other end of the fastening rod 13 passes through the through hole of the first fastening plate 10 and the oblong hole on the template 1 and is threadedly connected to the fastening screw block 14. When the fastening screw block 14 is rotated, the fastening rod 13 will drive the fastening block 12 to press the first fastener 2, thereby driving the second fastener 5 to press the embedded steel plate, so that the embedded steel plate is tightly fitted with the template 1. By providing an oblong hole on the template 1, the position of the fastening mechanism 3 can be easily adjusted, thereby facilitating the adjustment of the position of the embedded steel plate.

[0047] Furthermore, the adjustment mechanism 4 in this embodiment includes a top support 15, one end of which is slidably disposed within the second slide groove 8, and the other end of which is detachably and fixedly connected to the scaffolding. A support plate 16 is formed at one end of the top support 15, and the support plate 16 is slidably disposed within the second slide groove 8; a thread is formed in the middle of the top support 15, and a threaded sleeve 17 is installed on the top support 15, one end of which is operably abutted against the other end face of the template 1.

[0048] In this embodiment, if multiple embedded steel plates need to be installed at once, a second fastener 5 can be added. The cross-section of the second fastener 5 is I-shaped, and one end of the second fastener 5 is slidably disposed in the first groove 6. Then the second fastener 5 can be regarded as two first fasteners 2 arranged in opposite directions. The two sides of the second fastener 5 can fix two embedded steel plates, thereby improving the efficiency of installing embedded steel plates in the template 1.

[0049] In this embodiment, a technical solution is also provided: a method for installing a pre-embedded steel plate, which is accomplished by the above-mentioned installation device, including the following steps:

[0050] Step 1: Based on the pre-embedded position of the steel plate, establish positioning lines on both sides of the pre-embedded steel plate on template 1, perpendicular to the first groove 6. Specifically, in the construction of beam and column concrete structures, template 1 needs to be installed after the concealed acceptance of the reinforcing steel binding. First, the pre-embedded position and elevation of the steel plate must be located according to the design drawings. When installing template 1, leave the corresponding dimensions for installation at the pre-embedded steel plate location. Next, based on the pre-embedded position of the steel plate, mark the positioning lines on both sides of the pre-embedded steel plate on the upper and lower sides of the template 1. Align the two sides of the pre-embedded steel plate with the first groove 6 of template 1 and mark them. That is, the direction of the first groove 6 and the positioning lines are perpendicular to each other.

[0051] Step 2: Align the other two sides of the embedded steel plate with the first groove 6 on the template 1 and mark the corresponding first groove 6; after determining the positioning line, the installation elevation of the template 1 can be determined, so that the position of the upper and lower ends of the embedded steel plate can be accurately guaranteed when installing the template 1.

[0052] Step 3: Install the fastening mechanism 3 and the first fastener 2 on the marked first slide groove 6, and connect the other two sides of the pre-embedded steel plate to the already installed first fastener 2; during installation, place the first fastener plate 10 with the through hole of the first fastener 2 into the first slide groove 6.

[0053] Step 4: Align the two sides of the embedded steel plate with the positioning line and lock the embedded steel plate with the first fastener 2; move the embedded steel plate longitudinally so that its two sides are aligned with the positioning line, then move it laterally so that the other two sides of the embedded steel plate are aligned with the first groove 6 on the template 1 where the first fastener 2 is installed, so that the outer surface of the embedded steel plate is in contact with the inner surface of the template 1, and slide the installed first fastener 2 to a position 3-5 cm away from the end edge of the two sides of the embedded steel plate or 1 / 3-1 / 5 of the length of the embedded steel plate from the end edge. Adjust the second fastener plate 11 of the first fastener 2 to lock the inner side of the embedded steel plate, and adjust the first fastener plate 10 to lock the first wing plate 7 of the first groove 6 of the template 1. In this embodiment, the fastening rod 13 passes through the through hole of the first buckle plate 10 of the template 1 via the strip hole on the first slide groove 6. The position of the fastening rod 13 is adjusted within the strip hole at the bottom of the first slide groove 6. One end of the fastening rod 13 is screwed to the fastening block 12 to fix the first buckle plate 10. The other end of the fastening rod 13 is fastened to the fastening screw block 14 on the outer side of the template 1. A circular washer is fitted on the threaded end of the fastening rod 13 below the fastening screw block 14. By tightening the fastening screw block 14, the fastening rod 13 drives the fastening block 12 to press the first buckle plate 10, and drives the second buckle plate 11 to press the embedded steel plate, so that the embedded steel plate is initially fixed to the template 1.

[0054] Step 5: Assemble the template with the pre-embedded steel plate installed at the pre-embedded position, and install the top support 15 on the second slide 8; assemble the template 1 with the pre-embedded steel plate installed at the original reserved position, ensuring that the outer surface of the template 1 installed on site is tightly fitted to the inner wall of the template 1 and the four sides of the pre-embedded steel plate. Connect the support plate 16 in the second slide 8 to connect the top support 15.

[0055] Step Six: Connect the sliding top support 15 to the scaffolding and fix the template 1 to complete the fixing of the embedded steel plate. The sliding support plate 16 moves the top support 15 on the template 1. Then, connect the end of the top support 15 to the scaffolding and use the threaded sleeve 17 to fix the template 1 device. The position and elevation accuracy of the embedded steel plate can be readjusted by adjusting the top support 15 on the second slide groove 8.

[0056] It is worth noting that before locking the embedded steel plate with the first fastener 2, if multiple embedded steel plates need to be installed, a second fastener 5 is also installed between the two first fasteners 2. The second fastener 5, like the first fastener 2, has through holes and can be tightly installed through the fastening mechanism 3. Two embedded steel plates can be fixed on both sides of the second fastener 5 at the same time. After the template 1 is fixed, concrete can be poured and cured. When the concrete strength reaches the demolding requirements, the template 1 is removed: the top support 15 and the fastening mechanism 3 on the original template 1 are removed, and the nuts fixing the first fastener 2 and the second fastener 5 are further removed, so that the template 1 can be slid up or down to remove it. The template 1 can be reused, saving resources and meeting the requirements of safe and civilized construction. The remaining first fastener 2 and second fastener 5 can be partially cut, ground, and coated with anti-rust paint to make them flush with the embedded steel plate.

[0057] Compared with the prior art, the beneficial effects of the present invention are:

[0058] This invention proposes a pre-embedded steel plate installation device. A first fastener 2 can be installed using a first groove 6 on a template 1. The cooperation of two first fasteners 2 restricts the steel plate's fixation to the template 1. An adjustment mechanism 4 installed on a second groove 8 can adjust the position of the template 1 and connect it to the scaffolding for further fixation. After aligning the pre-embedded steel plate with the elevation, concrete can be poured. If the position of the pre-embedded steel plate changes during pouring, the position can be adjusted using a fastening mechanism 3 in conjunction with the first fasteners 2 and the adjustment mechanism 4, effectively ensuring the installation elevation and positional accuracy of the pre-embedded steel plate. Furthermore, after construction, the template 1 can be removed and reused by loosening the fastening mechanism 3 and the adjustment mechanism 4. The first fasteners 2, which are mixed into the concrete like the pre-embedded steel plate, only need to be ground smooth. The installation process is simple and easy to install and disassemble.
