A full assembly type slope protection frame beam joint structure

Abstract

This utility model relates to a fully prefabricated slope protection frame beam joint structure, including prefabricated node components and connecting beams. Each prefabricated node component has a central anchor bolt hole surrounded by four cross-shaped joints. Each joint includes a support portion with an upward-protruding tenon at its top. Two vertically embedded bolts are located on either side of the tenon. The connecting beam has a mortise at each end of its bottom surface, with two threaded holes penetrating the beam on either side of each mortise. The prefabricated node component is anchored to the slope using anchor bolts. Each joint connects to one end of a connecting beam, with one end of each connecting beam resting on the support portion of the joint. The tenon on the support portion is inserted into the mortise at the end of the connecting beam. The embedded bolts pass through the threaded holes on either side of the mortise and are screwed with anchor nuts onto the top surface of the connecting beam end. This utility model eliminates the wet joint pouring process in prefabricated frame beams, improving construction efficiency and ensuring construction quality.

Description

Technical Field

[0001] This utility model relates to the field of slope protection construction technology, and specifically to a fully prefabricated slope protection frame beam joint structure. Background Technology

[0002] Frame beams are a common slope protection and reinforcement structure, serving to strengthen slopes, limit surface soil deformation, and beautify the slope environment. Traditionally, frame beams for slope protection are constructed using cast-in-place methods, resulting in a large volume of on-site concrete pouring and low construction efficiency. To reduce the amount of on-site concrete pouring, prefabricated construction techniques are increasingly being adopted in the construction of frame beams for slope protection.

[0003] Patent CN1118360955A discloses a prefabricated frame beam and anchor cable combination reinforcement slope structure and its implementation method. Multiple frame beam connecting beams are prefabricated and arranged in a cross shape on the slope. Then, templates are set at the cross intersections, and anchor piers are poured to connect the connecting beams into a whole. Patent CN112962637A discloses a prefabricated slope protection frame beam and its construction method, prefabricating multiple cross-shaped nodes and multiple connecting beams. The cross nodes and connecting beams are connected on the slope using wet joints. While these methods can significantly reduce the amount of concrete poured, the large number of cross nodes and connecting beam joints, requiring concrete pouring at each joint and formwork erection at each pouring location, results in relatively low construction efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a fully prefabricated slope protection frame beam joint structure, which saves on-site concrete pouring procedures and further improves construction efficiency.

[0005] The technical solution of this utility model is as follows:

[0006] A fully prefabricated slope protection frame beam joint structure, comprising prefabricated node components and connecting beams, characterized in that:

[0007] The node prefabricated component has an anchor bolt through hole in the center, and four joints arranged in a cross shape are provided around the node prefabricated component. Each joint includes a support part, and the top of the support part has an upwardly protruding tenon. Two vertical pre-embedded bolts are provided on both sides of the tenon on the support part.

[0008] The bottom surface of each end of the connecting beam is provided with a tenon groove, and two screw holes that penetrate the connecting beam are provided on both sides of each tenon groove.

[0009] The precast node is anchored to the slope by anchor bolts through the central anchor bolt through hole. Each joint of the precast node is connected to one end of a connecting beam. One end of each connecting beam is pressed on the support part of the joint of the precast node. The tenon on the support part is inserted into the mortise at the end of the connecting beam. The pre-embedded bolts on both sides of the tenon pass through the screw holes on both sides of the mortise and are screwed into the top surface of the end of the connecting beam with anchor nuts.

[0010] The cross joint and connecting beam of this utility model adopt a mortise and tenon interlocking connection structure and are reinforced with bolts, which replaces the traditional wet joint construction, saves the on-site concrete pouring process, realizes the full assembly construction of the frame beam, and can greatly improve construction efficiency and ensure construction quality.

[0017] like Figures 1 to 5 As shown, this utility model includes a node prefabricated component 1 and a connecting beam 2;

[0018] like Figure 3 As shown, the node prefabricated component 1 has an anchor bolt through hole 11 in the center, and four joints arranged in a cross shape are provided around the node prefabricated component. Each joint includes a support part 12. The top of the support part 12 is provided with an upwardly protruding tenon 13. Two vertical pre-embedded bolts 14 are provided on both sides of the tenon on the support part.

[0019] like Figure 4 As shown, a tenon groove 21 is provided on the bottom surface of each end of the connecting beam 2, and two screw holes 22 that penetrate the connecting beam are provided on both sides of each tenon groove at both ends of the connecting beam.

[0020] like Figure 1 , Figure 2 and Figure 5As shown, the node precast component 1 is anchored to the slope by anchor bolts 3 through the central anchor bolt through hole. Each joint of the node precast component 1 is connected to one end of a connecting beam 2. One end of each connecting beam is pressed on the support part of the node precast component joint. The tenon 13 on the support part is inserted into the tenon groove 21 at the end of the connecting beam. The pre-embedded bolts 14 on both sides of the tenon pass through the screw holes on both sides of the tenon groove and are screwed onto the top surface of the end of the connecting beam with anchor nuts 4.

[0021] In a specific implementation of this utility model, the two ends of each connecting beam can be set as trapezoids, and two inclined surfaces 23 are provided on both sides of each connecting beam end. The angle of the inclined surfaces should be such that the inclined surfaces of the adjacent ends of the four connecting beams connected at each node fit closely together.

[0022] like Figure 5 As shown, in a specific implementation of this utility model, in order to ensure a more secure connection between the precast node component and the connecting beam, cement grout 5 can be injected into the joint between the tenon and the tenon strip, and into the screw hole where the pre-embedded bolt is inserted at the end of the connecting beam.

[0023] The construction method of this utility model is as follows:

[0024] like Figure 6 As shown, multiple precast nodes 1 are arranged in multiple rows on the slope 6 at a certain interval and anchored to the slope with anchor bolts. Then, connecting beams 2 are installed between adjacent precast nodes and anchored with bolts. Finally, grout is injected into the joints of the tenon and tenon and into the bolt holes to form a slope protection grid beam.
