Description

Technical Field

[0001] The invention belongs to the technical field of erecting slope building formwork, and in particular relates to a slope lattice beam formwork fixing structure and method. Background Art

[0002] As we all know, when pouring and forming slope-adjacent buildings such as highways, railways, and reservoirs, lattice beams are usually installed on the slopes to improve the overall strength of the slopes. The installation quality of such lattice beams directly affects the overall strength of the slopes and the stability of the roads or buildings.

[0003] In slope reinforcement operations, the structure used in the prior art for fixing the lattice beam formwork is: because the lattice beam is to be attached to the slope, after the slope serves as the bearing surface on one side, the lattice beam formwork is not supported on all four sides, and is generally supported on three sides or two sides (vertical lattice beams are supported on three sides, and horizontal lattice beams are supported on two sides).

[0004] When adopting this kind of support structure in the prior art, it has technical drawbacks, which are mainly reflected in: when the slope is a high and steep slope, the lateral pressure is too large during the slope formwork support, and the support structure can only be reinforced or improve the strength on the vertical surface, and cannot form a strong support on the side. After the concrete is poured, when vibrating, the formwork does not meet the sufficient vibration conditions. During strong vibration, the formwork support structure is unstable, which easily leads to problems such as mold expansion, misalignment, and leakage. During non-strong vibration, the gas in the concrete cannot be discharged, causing the lattice beam to have a honeycombed surface. The above situation has led to a dilemma in the support of such high and steep slope lattice beams.

[0005] Furthermore, in the prior art, a universal screw structure is used in conjunction with a template to realize the forming of the support structure. During the support process, multi-step support of the sides, bottom, and top is required. This support structure and method results in low efficiency and poor precision in the assembly and disassembly of the template.

In order to improve the extrusion stability, the cross-section of the extrusion block 26 is larger than the adjusting screw 22, the purpose of which is to increase the force-applying surface and improve the stability under the extrusion state.

[0021] A positioning member 24 is provided on the outer wall of the threaded sleeve 23. The positioning member 24 adopts a non-rotating cross-section structure, and its purpose is to slide in the recessed grooves on the vertical reinforcement component 1 and the horizontal reinforcement component 4 without self-rotation, so that the operator can operate with one hand when the adjustment screw 22 is suspended. In this embodiment, the positioning member 24 is obtained by cutting a circular surface symmetrically on both sides of a cylindrical structure.

[0022] In the present technical solution, the anchor 3 includes an embedded rod 30, on which an external thread 32 is provided, and a positioning plate 33 and a positioning nut 34 are provided in conjunction with the external thread 32. The positioning plate 33 and the positioning nut 34 are arranged on the outside of the vertical beam top frame 11 and the horizontal beam top frame 41.

[0023] The embedded rod 30 is provided with an anti-slip structure and a straight section 35, and the straight section 35 is arranged at the rear side of the anti-slip structure. The anti-slip structure adopts an anti-slip protrusion or a barb structure 31, and the anti-slip protrusion can be a sheet or block structure. The barb structure 31 is adopted in this embodiment. When in use, the straight section 35 is inserted into the pre-drilled hole to achieve temporary positioning and fixation, and the barb structure 31 is fixed in the concrete of the slope grouting area 60 and the barb structure 31 is conducive to increasing adhesion and resisting the lateral pressure of the concrete.

[0024] As an important structure, the bottom frame 42 is provided with an angle adjustment component 5. In this embodiment, the angle adjustment component 5 includes a hinged positioning member 51 welded on the bottom frame 42 and a lifting adjustment member 52 of one or more movable structures; the hinged positioning member 51 includes a positioning threaded sleeve 512, and a positioning adjustment screw 511 is provided inside the positioning threaded sleeve 512. The top of the positioning adjustment screw 511 is hingedly provided with a slider I; the lifting adjustment member 52 has the same structure as the positioning locking component 2, including a threaded sleeve 23, and the lifting adjustment member 52 includes a threaded sleeve 23.

Figure 6 As shown, through the above structural setting, since the bottom surface of the transverse beam 62 needs to be perpendicular or nearly perpendicular to the slope 6, the support plate 54 and the angle adjustment template 71 need to have a certain slope. When adjusting the slope, the slope change will cause the distance between the hinged positioning member 51 and the lifting adjustment member 52 to change. Therefore, the support plate 54 must be able to perform sliding compensation between the hinged positioning member 51 and the lifting adjustment member 52.

[0025] The angle adjustment component 5 uses the hinged positioning member 51 as a fulcrum, and the slider I53 on the top can rotate in place but cannot move. The lifting adjustment member 52 serves as an adjustment member, and the slider II531 on the top can rotate and move, thereby achieving the purpose of adjusting the slope of the support plate 54 and the angle adjustment template 71.

The concrete grade is C20, and it is left to stand for more than 24 hours after spraying. Step 5: Tie the lattice beam reinforcement in the vertical beam 61 and the transverse beam 62 according to the marked area; when the formwork of the vertical beam 61 is supported, the anchor rod 63 serves as an outer blocking member of the side support wood 8, which limits and supports the vertical beam 61 and the outer periphery of the formwork 7 and the wood 8; Install the vertical reinforcement assembly 1 on the outer side of the template 7 of the vertical beam 61; anchor the vertical reinforcement assembly 1 on the outer side of the vertical beam 61 by adjusting the position of the positioning nut 34 on the outer side of the embedded rod 30; adjust the positioning and locking assembly 2 on the left frame 12, the right frame 13 and the top frame 11 of the vertical beam, and squeeze the wooden square 8 through the squeezing block 26; Install the transverse reinforcement assembly 4 on the outer side of the template 7 of the transverse beam 62; anchor the transverse reinforcement assembly 1 on the outer side of the transverse beam 62 by adjusting the position of the positioning nut 34 on the outer side of the embedded rod 30; adjust the positioning locking assembly 2 on the top frame 41 of the transverse beam, and squeeze the wooden square 8 through the squeezing block 26; during the installation process, in order to ensure the installation efficiency and clamping strength, the vertical interval between each two adjacent vertical reinforcement assemblies 1 is 500 mm; the horizontal interval between each two adjacent transverse reinforcement assemblies 4 is 500 mm; Step 6: Adjust the angle adjustment assembly 5 on the bottom frame 42, with the hinged positioning member 51 as the fulcrum and the lifting adjustment member 52 as the adjustment member, and move the lifting adjustment member 52 as a whole to a suitable position in the bottom frame sink 44, and then screw the adjustment screw 22, so that the slider II 531 on the top thereof descends, so as to achieve the purpose of adjusting the slope of the angle adjustment template 71, so that the support plate 54 and the angle adjustment template 71 are perpendicular to or nearly perpendicular to the slope 6 and are supported on the wooden square 8 below the template 7 of the transverse beam 62; Step 7: pour concrete into the steel cages of the transverse beam 62 and the vertical beam 51, and vibrate vigorously during pouring, and let it stand for 24 hours after pouring; Step eight: remove the mold, cut off the embedded rods 30 on the top surfaces of the vertical beams and the transverse beams; pull out or cut off the anchor rods 63, and trim the shapes of the vertical beams 61 and the transverse beams 62.
