Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an embedded part and its construction method that facilitates the installation of steel beams and enables sealing and repositioning. Background Technology

[0002] In recent years, with the rapid development of steel structures, steel-concrete composite structures have become a commonly used structural form. The connection between the steel structure and concrete requires embedded parts, which are pre-embedded within the concrete components during pouring to facilitate the later installation and fixing of the external steel structure.

[0003] The conventional method for installing embedded parts during construction is to first fix the embedded parts to the steel cage of the concrete component. However, the embedded parts may shift in position during the concrete pouring and curing process. Due to the obstruction of the formwork, it is difficult to re-measure and correct the position of the embedded parts, thereby reducing the construction speed and quality.

[0004] Conventional embedded parts, fixed to the reinforcing cage of reinforced concrete components, experience vibrations during concrete pouring, leading to significant positioning deviations and poor construction quality. Furthermore, the lack of temporary support points for the connection between the steel beam and the embedded parts makes construction time-consuming and labor-intensive. Summary of the Invention

[0005] This invention primarily addresses the shortcomings of existing embedded component construction methods, such as the difficulty in re-measurement and positioning. It provides an embedded component and its construction method that facilitates re-measurement and positioning during steel beam installation, overcoming the drawbacks of traditional embedded component construction methods and improving construction speed and reliability. During the construction phase, it effectively re-measures the embedded component's positioning, improving the accuracy of embedded component positioning and the reliability of project quality and safety.

[0006] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions:

[0007] An embedded component for facilitating the installation of steel beams and enabling sealing and repositioning includes a reinforced concrete component. The outer end face of the reinforced concrete component is provided with an embedded plate integrally cast and interlocked with the component. The rear end of the embedded plate is provided with several anchor bars integrally cast with the reinforced concrete component. The embedded plate is provided with bolt fittings that interlock with it. The inner side of the embedded plate is provided with nuts that interlock with the bolt fittings. The lower outer side of the embedded plate is provided with supporting angle steel that interlocks with and is fixed to the bolt fittings. The supporting angle steel has a pair of through holes I that interlock with the bolt fittings.

[0008] Preferably, a sealing steel plate is provided between the nut and the reinforced concrete component, and is nested and connected to the reinforced concrete component.

[0009] Preferably, a washer is provided between the nut and bolt fitting and the supporting angle steel, and the washer is provided with a through hole II that fits into the bolt fitting.

[0010] A construction method for embedded parts that facilitates formwork sealing and repositioning during steel beam installation includes the following steps:

[0011] Step 1: Cut the embedded plate and anchor bar according to their dimensions and shape, and then weld them.

[0012] Step 2: After verifying the positioning of the anchor bars, set 3 bolt holes on the embedded plate. The bolt holes are distributed in a triangle and kept aligned with the center of the bolt holes. Weld the nuts to the side of the embedded plate near the concrete beam.

[0013] Step 3: Before pouring the reinforced concrete components, set 3 bolt holes in the wooden formwork. The size and spacing of the holes should be consistent with the bolt holes on the embedded plate.

[0014] Step 4: Set through hole II at the center of the gasket. The size of through hole II is the same as the bolt hole on the pre-embedded plate.

[0015] Step 5: Next, tighten and secure the wooden formwork to the embedded plate using bolts, nuts, and other fittings. This method of connecting and fixing the concrete formwork to the embedded plate facilitates the re-measurement of the embedded parts' positions, improves construction speed, and better ensures the quality of the embedded parts' construction.

[0016] Step 6: Concrete pouring is carried out. Before the concrete pouring process is completed and the initial setting process is completed, the anchor position is checked by measuring the position of the bolt fittings. If the position is offset, the anchor of the target embedded part is adjusted and the process is returned to the execution step.

[0017] Step 7: After the concrete has been poured and cured, unscrew the bolts to separate the embedded plate from the wooden formwork.

[0018] Step 8: Connect the supporting angle steel to the embedded plate using bolts to serve as a temporary support for the steel beam installation. By connecting and fixing the embedded plate to the angle steel, a temporary support point is formed, facilitating the installation of the steel beam.

[0019] Step 9: After the steel beams are installed and their positions are verified, remove the supporting angle steel.

[0020] Preferably, wooden formwork is used to limit the structure and dimensions of the embedded plate, anchor bar and reinforced concrete component in the integrated casting. After the reinforced concrete component has solidified, the wooden formwork is removed.

[0021] As a preferred option, shims are installed to eliminate the gap between the bolt fittings and the wooden template and supporting angle steel during locking and pressing.

[0022] Preferably, when the nut of the bolt fitting is welded to the embedded plate, a sealing steel plate is welded to the end face of the nut to prevent concrete from filling the nut and affecting the threaded connection between the bolt and the nut of the bolt fitting. By welding the sealing steel plate to the inner side of the nut near the concrete, the threads of the nut are protected from contamination and the bolt can be easily removed and demolded later.

[0023] Preferably, the allowable offset distance of the bolt center of the bolt assembly is 3mm, the allowable deviation length of the exposed bolt is ±30mm, and the allowable deviation length of the thread of bolt 4 is ±30mm.

[0024] As a preferred method, when pouring concrete, the pouring point should be staggered from the embedded plate and anchor bars by a distance of not less than 20cm. This prevents the concrete from falling directly onto the embedded plate and anchor bars, thus effectively avoiding the skewing of the embedded parts under the impact of the concrete and improving the installation effect and efficiency of the embedded parts.

[0025] As a preferred method, during the pouring of reinforced concrete components, it is necessary to continuously compact the concrete with a vibrator. When using the vibrator, it is necessary to control the vibrator to avoid contact with the embedded plate and anchor bars, so as to avoid affecting the position of the embedded plate and anchor bars during the process of vibrating and compacting the concrete, thereby reducing the workload of adjusting the position of the embedded parts later.

[0026] The present invention can achieve the following effects:

[0027] This invention provides an embedded component and its construction method that facilitates the sealing and repositioning of steel beams during installation. Compared with existing technologies, it overcomes the drawbacks of traditional embedded component construction methods, which suffer from difficulties in repositioning, and improves construction speed and reliability. It effectively repositions the embedded component during the construction phase, enhancing the accuracy of embedded component positioning and the overall quality and safety of the project.

[0035] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0036] Example: Figure 1-6 As shown, an embedded component for facilitating the installation of steel beams and enabling sealing and repositioning includes a reinforced concrete component 3. An embedded plate 1, integrally cast and fitted with the reinforced concrete component 3, is provided on the outer end face of the component 3. Six anchor bars 4, integrally cast with the reinforced concrete component 3, are provided at the rear end of the embedded plate 1. Bolt fittings 2, fitted with the embedded plate 1, are provided on the embedded plate 1. Nuts 11, fitted with the bolt fittings 2, are provided on the inner side of the embedded plate 1. A sealing steel plate 7, nested and connected to the reinforced concrete component 3, is provided between the nut 11 and the reinforced concrete component 3. A supporting angle steel 8, fitted and fixed to the bolt fittings 2, is provided on the lower outer side of the embedded plate 1. A pair of through holes I 9, fitted with the bolt fittings 2, are provided on the supporting angle steel 8. A washer 6, fitted with the bolt fittings 2, is provided between the nut / bolt fittings 2 and the supporting angle steel 8. A through hole II 10, fitted with the bolt fittings 2, is provided on the washer 6.

[0037] A construction method for embedded parts that facilitates formwork sealing and repositioning during steel beam installation includes the following steps:

[0038] Step 1: Cut the embedded plate 1 and anchor bar 4 according to their dimensions and shapes and then weld them.

[0039] Step 2: After verifying the positioning of anchor bar 4, set 3 bolt holes on the embedded plate 1. The bolt holes are distributed in a triangle and kept consistent with the center of the bolt holes. Weld nut 11 to the side of the embedded plate near the concrete beam.

[0040] When the nut 11 is positioned and welded to the embedded plate 1, the nut 11 and the reinforced concrete component 3 are sealed by welding a steel plate 7 to the end face of the nut to prevent the concrete from filling the nut 11 and affecting the threaded connection and fixation between the bolt fitting 2 and the nut 11.

[0041] Step 3: Before pouring the reinforced concrete component 3, set 3 bolt holes on the wooden formwork 5. The size and spacing of the holes are consistent with the bolt holes on the embedded plate 1.

[0042] Step 4: Set a through hole II10 at the center of the shim 6. The size of the through hole II10 is consistent with the bolt hole on the embedded plate 1. The gap between the nut and bolt fitting 2 and the wooden template 5 and the supporting angle steel 8 is eliminated by installing the shim 6.

[0043] Step 5: Next, use bolts 2 and nuts 11 to press and fix the wooden template 5 to the embedded plate 1.

[0044] The allowable offset distance of the bolt center of bolt accessory 2 is 3mm, the allowable deviation length of the exposed bolt is ±30mm, and the allowable deviation length of the bolt thread is ±30mm.

[0045] Step 6: Concrete pouring is carried out. Wooden formwork 5 is used to integrate the embedded plate 1, embedded part 4 and reinforced concrete component 3 for structural and dimensional constraints. After the reinforced concrete component 3 has solidified, the wooden formwork 5 is removed.

[0046] When pouring concrete, the pouring point is staggered from the embedded plate 1 and the anchor bar 4 by a distance of not less than 20cm. This prevents the concrete from falling directly onto the embedded plate 1 and the anchor bar 4, thus effectively avoiding the skewing of the embedded parts under the impact of the concrete and improving the installation effect and efficiency of the embedded parts.

[0047] During the pouring of reinforced concrete component 3, it is necessary to continuously compact it with a vibrator. When using the vibrator, it is necessary to control the vibrator to avoid contact with the embedded plate 1 and anchor bar 4, so as to avoid affecting the position of the embedded plate 1 and anchor bar 4 during the process of vibrating and compacting the concrete, thereby reducing the workload of adjusting the position of the embedded parts later.

[0048] Before the concrete pouring process is completed and the initial setting process is completed, the position offset of the anchor bar 4 is detected by measuring the position of the nut and bolt accessory 2. If the position is offset, the target embedded anchor bar 4 is adjusted and the execution step is returned.

[0049] Step 7: After the concrete has been poured and cured, unscrew the bolts to separate the embedded plate 1 from the wooden formwork 5.

[0050] Step 8: Connect the supporting angle steel 8 to the embedded plate 1 with bolts to serve as a temporary support for the steel beam installation.

[0051] Step 9: After the steel beams are installed and their positions are verified, remove the supporting angle steel 8.

[0052] In summary, this embedded part and its construction method, which facilitates the sealing and repositioning of steel beams during installation, overcomes the drawbacks of traditional embedded part construction methods, which suffer from difficulties in repositioning, and improves construction speed and reliability. It effectively re-measures the embedded part's positioning during the construction phase, enhancing the accuracy of embedded part positioning and the overall quality and safety of the project.

[0053] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
