Description

Technical Field

[0001] This utility model relates to the field of slope protection construction technology, and to a novel 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 novel 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 novel prefabricated slope protection frame beam joint structure includes a node prefabricated component and four I-beams. The node prefabricated component has a central anchor bolt through-hole, and four cross-shaped joints are arranged around it, each joint having a slot at its bottom. Each I-beam has two through-holes for reinforcing bars. The node prefabricated component is anchored to the slope via the anchor bolt through-hole, and one end of each of the four I-beams is respectively embedded in the slots at the bottom of the four joints of the node prefabricated component.

[0007] This utility model has a simple structure and adopts a joint connection structure in which the beam end of the single beam is fixed to the groove of the precast node component. This saves the on-site concrete pouring process, speeds up construction, helps to shorten the construction period, and ensures a firm connection, thus guaranteeing construction quality. This is conducive to the further promotion and application of prefabricated frame beams. Attached Figure Description

[0011] Figure 4 This is a schematic diagram of the construction method of this utility model. Detailed Implementation

[0012] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model includes a node precast component 1 and four I-beams 2. The node precast component 1 has an anchor rod through hole 11 at its center and four joints 12 arranged in a cross shape around the node precast component. Each joint 12 has a slot 13 at its bottom. Each I-beam 2 has two vertically penetrating steel bar holes 21. The node precast component 1 is anchored to the slope by anchor rods 3 through the anchor rod through hole. One end of each of the four I-beams 2 is respectively embedded in the slots 13 at the bottom of the four joints of the node precast component.

[0013] The construction method of this utility model is as follows:

[0014] (1) Trim the slope 4, drill holes and insert anchor rods 3 at the design positions of each node of the frame beam on the plane, and grout to ensure that the pull-out strength of the anchor rods meets the design requirements; excavate the node prefabricated component installation groove around each anchor rod on the slope, with a groove depth of 20-40cm (smaller value for rock slopes and larger value for soil slopes).

[0015] (3) Mark out the plan position of each beam on the slope and dig the beam installation groove. The groove depth is 10cm greater than the groove depth of the node precast component. According to the position of the steel bar hole on the beam, the temporary anchor steel bar is anchored into the slope rock and soil body for a certain length using mechanical pressure. The exposed length of the temporary anchor steel bar is the same as the height of the beam precast component.

[0016] (4) Hoist the beam 2 into the beam installation slot on the slope, and insert the upper end of the temporary anchoring steel bar into the steel bar hole on the beam to temporarily fix the beam.

[0017] (5) Hoist the node precast component 1 into the installation groove, insert the upper end of the anchor rod into the anchor rod through hole in the center of the node precast component, and at the same time align the four grooves of the node precast component with the ends of the beam, press down on the node precast component, so that the ends of the beam component are embedded in the grooves at the bottom of the node precast component.

[0018] (6) Tension the anchor rods, press the precast node components and the straight beam onto the slope, and then seal the anchor rod holes to form the overall load-bearing system of the frame beam.
