Description

Technical Field

[0001] This utility model belongs to the field of steel structure, specifically relating to a pre-embedded anchor plate installation structure and a steel roof support installation structure on a beam. Background Technology

[0002] At the joint between the steel structure support and the concrete, pre-embedded anchor plates are generally installed. These anchor plates are securely embedded in the concrete with their upper surface exposed, and the steel structure support is connected to the upper surface of the anchor plate. To ensure a secure connection between the anchor plate and the concrete, shear members and pre-embedded anchor rods are typically installed on the anchor plate. However: traditional anchor plates use a single large-sized shear member, requiring large holes to be pre-drilled in the beam surface. This forces the main reinforcement bars of the beam to be cut off or rerouted, weakening the overall load-bearing capacity of the beam. This can lead to stress concentration at the center of the support, easily causing localized concrete cracking at the support location. Furthermore, pre-embedded anchor rods are expensive to manufacture and require machining of external threads. Using double nuts to lock the anchor rod onto the anchor plate results in high processing costs and stringent positioning requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a pre-embedded anchor plate installation structure and a beam-mounted steel roof support installation structure including the above structure. The pre-embedded anchor plate installation structure can avoid interference with the internal steel bars, and reduce the cost and processing difficulty.

[0004] The technical solution adopted in this utility model is: An embedded anchor plate installation structure is disclosed, wherein the embedded anchor plate is embedded in a reinforced concrete structure with its upper surface exposed; shear-resistant members and anchor bars are welded to the lower side of the embedded anchor plate, the shear-resistant members are distributed around the embedded anchor plate, and the anchor bars are spaced throughout the embedded anchor plate; short anchor bars of the same type are welded to one side of the lower end of the anchor bars, the anchor bars are longer than the shear-resistant members, and both the shear-resistant members and the anchor bars avoid the internal reinforcing bars; a casting hole is opened at the center of the embedded anchor plate, and vent holes are opened around the perimeter, the casting hole being larger than the vent holes.

[0005] Preferably, the embedded anchor plate is circular, and the distance between each shear-resistant component and the center of the embedded anchor plate is equal and they are evenly distributed about the center. The distance between each vent hole and the center of the embedded anchor plate is equal and they are evenly distributed about the center.

[0006] Preferably, the shear-resistant components and vent holes are equidistant from the center of the pre-embedded anchor plate, and the shear-resistant components and vent holes are staggered.

[0007] Preferably, four shear-resistant components and four ventilation holes are used.

[0008] Preferably, the anchor bars are evenly distributed in a rectangular array on the underside of the pre-embedded anchor plate.

[0009] Preferably, the upper end of the anchor bar is inserted into the corresponding groove on the pre-embedded anchor plate and then welded.

[0010] Preferably, the upper end of the shear-resistant component is inserted into the corresponding groove on the pre-embedded anchor plate and then welded.

[0011] Preferably, the shear-resistant component is an H-type shear-resistant component.

[0012] A steel roof support installation structure on a beam includes a support, a pre-embedded anchor plate, and a reinforced concrete beam. The upper end of the support is used to weld and support the steel column of the steel roof, and the lower end is welded and supported on the pre-embedded anchor plate. The pre-embedded anchor plate is embedded in the reinforced concrete beam and its upper surface is exposed. The pre-embedded anchor plate adopts the above-mentioned pre-embedded anchor plate installation structure.

[0013] Preferably, the support is a ball joint support.

[0014] The beneficial effects of this utility model are: This pre-embedded anchor plate installation structure divides the central shear-resistant component into surrounding shear-resistant components, which can not only disperse concentrated stress to the surrounding area, but also reduce the size of the shear-resistant components and avoid interference with the internal reinforcement. This pre-embedded anchor plate installation structure uses anchor bars instead of anchor rods and welds short anchor bars of the same type to one side of the lower end of the anchor bars. While ensuring the bearing capacity of the node, there is no need to process external threads and install double nuts, which reduces the cost and processing difficulty. The ventilation holes of this pre-embedded anchor plate installation structure can effectively prevent the concrete from becoming hollow during pouring. Attached Figure Description

Before installing the embedded anchor plate 1, foam blocks are first placed at the corresponding positions of the embedded anchor plate 1 on the reinforced concrete structure. After the reinforced concrete structure is poured, the foam blocks are first removed, and then the embedded anchor plate 1 is positioned and placed in the concrete. The pouring hole is then used to pour the concrete until the voids in the reinforced concrete structure are filled. After the strength conditions are met, the embedded anchor plate 1 and the reinforced concrete structure form an integral structure.

[0023] The embedded anchor plate installation structure divides the central shear-resistant member 2 into four surrounding shear-resistant members 2, which can not only disperse the concentrated stress to the surrounding area, but also reduce the size of the shear-resistant member 2 and avoid interference with the internal reinforcement. The embedded anchor plate installation structure uses anchor bars 3 instead of anchor rods and welds short anchor bars 4 of the same type on one side of the lower end of the anchor bars 3. While ensuring the bearing capacity of the node, there is no need to process external threads and install double nuts, which reduces the cost and processing difficulty. The vent holes 6 of the embedded anchor plate installation structure can effectively prevent the concrete from becoming hollow during pouring.

[0029] Example 2 This embodiment discloses a steel roof support installation structure on a beam, such as... Figures 3 to 5 As shown, the structure includes a support 8, an embedded anchor plate 1, and a reinforced concrete beam 9. The upper end of the support 8 is used to weld and support the steel column 7 of the steel roof, and the lower end is welded and supported on the embedded anchor plate 1. The embedded anchor plate 1 is embedded in the reinforced concrete beam 9 with its upper surface exposed. The embedded anchor plate 1 adopts the embedded anchor plate installation structure in Example 1. After the embedded anchor plate 1 is embedded and installed on the reinforced concrete beam 9 and the structure is stable, the support 8 and the steel column 9 are welded onto the embedded anchor plate 1 in sequence, and finally the steel roof is erected.

[0030] In this embodiment, as Figure 3 and Figure 5 As shown, support 8 is preferably a ball joint support, which avoids stress concentration in rigid connections, can release stress, and has good seismic resistance.
