Description

Technical Field

[0001] This utility model relates to the field of frame beam formwork technology, and in particular to a combined frame beam formwork structure. Background Technology

[0002] Currently, frame beams are commonly used to protect severely weathered rock slopes and stable soil slopes. Traditional frame beam formwork often employs a "plywood + timber backing" method, resulting in low formwork turnover, high overall amortization costs, and inconsistent timber backing spacing. Furthermore, under the lateral pressure of pouring, the formwork is prone to bulging and edge bursting, leading to poor concrete appearance. In recent years, many projects have adopted a hybrid method of "aluminum frame + timber formwork filling" for frame beam construction. However, aluminum and timber formwork are made of different materials, resulting in significant differences in water absorption and temperature-induced deformation. This can lead to "step-like" misalignments at the joints, affecting the consistency of the concrete surface. This application addresses these shortcomings. Utility Model Content

[0003] The purpose of this utility model is to provide a combined frame beam formwork structure, in which the combined frame beam formwork can avoid the problems of poor appearance and surface consistency of concrete molding, and is sturdy, durable and has a long service life.

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0031] A type of composite frame beam formwork structure, such as Figures 1-5 It includes a cross-connecting template 1, a top template 2, a side template 3, and a template reinforcement component 4.

[0032] like Figure 2 The cross-connecting template 1 is a steel mold with a cross shape. Bolts 5 are welded on the cross-connecting template 1 in four directions. Preferably, two sets of bolts 5 are set in each direction to connect the top mold 2 in the four directions.

[0033] like Figure 3The top mold 2 is a steel mold with a frame at the edge. The frame is a rectangular square tube welded from square tubes to improve the strength of the template. Steel pipe supports 21 are welded at the diagonal of the rectangular square tubes, so that the two steel pipes form a scissor brace structure, which further increases the strength of the template.

[0034] The rectangular square tube has a reserved hole 6 on its short side. The axes of the reserved holes 6 at both ends are in a cross structure. The bolt 5 is inserted into the reserved hole 6 and the nut is used to fix it, so that the connection between the cross connection template 1 and the top mold 2 can be completed.

[0035] At least two sets of reserved holes 6 are provided at each end of the top mold 2 to ensure stable connection.

[0036] The top mold 2 has slide rails 22 on both long sides.

[0037] Adjacent top molds 2 are connected by connectors, including threaded steel bars 7, nuts 8, and washers 9. The threaded steel bars 7 pass through pre-drilled holes 6, and the nuts 8 and washers 9 are installed on the threaded steel bars 7, thus connecting two adjacent sets of top molds 2. Figure 4 The two top molds 2 are mechanically connected by threaded steel bars 7 passing through two reserved holes 6 and nuts 8. Washers 9 are installed between nuts 8 and reserved holes 6. After the two top molds 2 are connected, the left and right ends of the whole are connected to the cross-connecting templates 1 on both sides respectively.

[0038] like Figure 3 The side mold 3 is a steel mold with a frame at the edge. The frame is a rectangular square tube welded from square tubes to improve the strength of the template. Steel pipe supports 21 are welded at the diagonal of the rectangular square tubes, so that the two steel pipes form a scissor brace structure, which further increases the strength of the template.

[0039] The long side of the side mold 3 is provided with a groove 10 for cooperating with the slide rail 22. The slide rail 22 and the groove 10 cooperate to form a sliding connection. After the side mold 3 and the top mold 2 are assembled, the interior forms a space for pouring concrete.

[0040] The cross-connecting template 1, top mold 2 and side mold 3 are all made of steel molds to avoid deformation differences due to different materials. Metal materials have high strength and long service life.

[0041] like Figure 5The template reinforcement component 4 is used to reinforce the assembled top mold 2 and side mold 3. It includes two sets of template clamps 11, a fastening device 12 for fastening the template clamps 11, and a steel rod 15 for inserting into the ground. The two sets of template clamps 11 are combined and surround the outside of the top mold 2 and side mold 3. The steel rod 15 is connected to the template clamps 11. A rubber layer 13 is provided at the contact position between the template clamps 11 and the top mold 2 and side mold 3. The rubber layer 13 serves to prevent grout leakage at the joint. The template clamps 11 are provided with a limiting ring 14 for the steel rod 15 to pass through. After the fastening device 12 fastens the template clamps 11, the steel rod 15 passes through the limiting ring 14 and is driven into the ground. The top plate of the steel rod 15 is provided with a bent section that prevents it from passing through the limiting ring 14. The fastening device 12 includes a screw and a nut.

[0042] The two sets of template clamps 11 of the template reinforcement device 4 form a "clamp-like" structure. When in use, the template reinforcement device 4 is placed at the 1 / 2 position of the top formwork and at the top formwork connection, and the template clamps 11 are clamped on the outside of the template. The template clamps 11 are tightened by the fastening device 12, which consists of a screw and nuts that are fastened at both ends. There is rubber 13 inside the template clamps 11, which has the function of preventing grout leakage at the joint. Limiting rings 14 are welded on both sides of the template clamps 11. The steel rods 15 are inserted into the soil through the limiting rings 14 to play a secondary reinforcement role, which can effectively prevent concrete bulging.

[0043] A type of slope protection, such as Figure 7 The system includes a frame beam 20, vegetation bags 16 set in the internal grid of the frame beam 20, a rapid flow channel 17, and a C25 concrete drainage ditch 19. The frame beam 20 is cast using a composite frame beam formwork structure. The rapid flow channel 17 is composed of multiple precast blocks 18 in an isosceles trapezoidal structure, which are overlapped, spliced, or tenoned together, with the joints filled with mortar. Surface water from the slope flows through the rapid flow channel 17 into the drainage ditch 19 for discharge. The drainage ditch 19 is a C25 concrete cast-in-place structure to prevent water accumulation from damaging the slope stability.

[0044] Vegetation bags 16, filled with soil and grass seeds, are placed inside the frame beam. The exterior of the vegetation bags 16 is reinforced with a "cross-shaped" steel mesh and steel bars. This allows for rapid vegetation cover formation while preventing soil erosion. The vegetation bags 16 and the frame beam work together to significantly improve the safety, durability, and ecological friendliness of the frame beam slope.

[0045] The main steps of slope protection construction include: cleaning the slope surface → positioning and setting out lines → constructing the rapid flow channel → excavating the trench → erecting the formwork → pouring the frame beam → stacking the vegetation bags → watering and curing.
