Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a stepped foundation formwork reinforcement device. Background Technology

[0002] The foundation is a crucial component of a building, playing a vital role in its stability and lifespan. Stepped independent foundations are a relatively new type of foundation with good performance characteristics. Stepped independent foundations are typically constructed using poured concrete. Formwork needs to be erected during construction for concrete pouring.

[0003] Traditional stepped foundation formwork construction has the following defects: 1. Fixed-size wooden frame cannot adapt to different size changes, resulting in a material waste rate of up to 30%; 2. The wooden formwork and support system are fixed by nailing, and repeated disassembly and assembly lead to serious damage to the formwork; 3. The angle adjustment of the diagonal bracing relies on manual nails and wooden wedges, and uneven support force leads to formwork displacement (deviation exceeding 5mm / m); 4. The existing expansion joint locking is unreliable, and slippage and deformation are prone to occur under the lateral pressure of concrete.

[0004] Chinese utility model patent CN214363580U, published on October 8, 2021, discloses a circumferential casting mold for a stepped independent foundation. The mold includes an inner baffle, outer columns, and an outer hoop. The inner baffle is vertically arranged, the outer columns are evenly distributed on the outer side of the inner baffle, and the outer hoop is arranged vertically parallel to the outer side of the columns. The inner baffle is a cylindrical structure formed by rectangular plates. Countersunk holes are evenly distributed vertically on the inner side of the inner baffle. Hooks with a channel steel cross-section are symmetrically arranged on the outer sides of both ends of the inner baffle. The hooks are connected to the ends of the inner baffle by screws, and the hooks on both sides are connected by C-shaped grooves. The circumferential casting mold for the stepped independent foundation forms a cylindrical independent foundation enclosure by setting outer columns on the outer side of the rubber inner baffle and fixing the columns in a ring shape with the outer hoop. However, this circumferential casting mold is mainly suitable for cylindrical independent foundations and not for square, large-section stepped independent foundations, and it cannot provide adequate support and reinforcement. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model proposes a large-section stepped independent foundation template reinforcement device to solve the problem that the existing technology lacks a suitable large-section stepped independent foundation for square structures and cannot provide adequate support and reinforcement.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A large-section stepped independent foundation formwork reinforcement device includes at least two layers of frame systems. The upper frame system is supported on top of the lower frame system. The inner side of the frame system has a U-shaped groove for inserting the formwork, and the outer side of the frame system is connected to a diagonal bracing system. This invention facilitates the step-by-step installation of the stepped independent foundation formwork by connecting the upper frame system to the lower frame system. The U-shaped groove on the inner side of the frame system facilitates formwork placement, and the diagonal bracing system on the outer side, supported by the ground, reinforces the frame system, making the stepped independent foundation formwork more robust.

[0008] Furthermore, the bracing system includes a frame connecting column connected to the frame system and a bracing assembly hinged to the frame connecting column.

[0009] Furthermore, the diagonal bracing assembly includes a diagonal brace hinged to the frame connecting column and an anchor rod disposed at the other end of the diagonal brace.

[0010] Furthermore, the lower end of the diagonal brace is provided with a insert plate, and the anchor rod is inserted into the ground after being connected to the insert plate.

[0011] Furthermore, both the upper and lower skeleton systems include an upper skeleton and a lower skeleton, and the upper and lower skeletons of each skeleton system are connected by skeleton connecting columns.

[0012] Furthermore, both the upper and lower skeletons include at least two horizontally arranged transverse skeletons and at least two horizontally arranged longitudinal skeletons, with the transverse and longitudinal skeletons vertically connected to form a rectangular frame structure.

[0013] Furthermore, the frame connecting column includes a vertical column and transverse connecting pieces connected to the upper and lower ends of the vertical column. The transverse connecting pieces at the upper and lower ends are respectively connected to the transverse or longitudinal frames of the upper and lower frames.

[0014] Furthermore, both the transverse and longitudinal frames are rectangular steel, and the transverse connectors are short rectangular steel.

[0015] Furthermore, the upper and lower transverse connectors are respectively provided with column connection holes, and the transverse skeleton and / or longitudinal skeleton are respectively provided with corresponding skeleton connection holes. The transverse connectors are fixedly connected to the corresponding transverse skeleton or longitudinal skeleton by inserting screws and connecting nuts.

[0016] Furthermore, the lower frame of the upper frame system is connected to the upper frame of the lower frame system; the transverse frame and / or longitudinal frame includes an inner square steel and an outer square steel sleeved on the outside of the inner square steel, the inner square steel and the outer square steel are slidably fitted, and the inner square steel and the outer square steel are provided with multiple corresponding through holes for passing through locking bolts.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model is a skeleton template that connects the upper skeleton system to the lower skeleton system, making it easy to support and form a stepped independent foundation step by step.

[0019] 2. This utility model makes the frame template of the stepped independent foundation more stable by setting a diagonal bracing system on the outside of the frame system. The diagonal bracing system is supported on the ground to reinforce the frame system.

[0020] 3. Each layer of the frame system of this utility model is constructed by square steel, and the upper and lower steel bars of the same layer frame system are connected by frame connecting columns to increase the stability of the frame system.

[0021] 4. The horizontal and vertical frames of each layer of the frame system of this utility model are both telescopic structures, making the frame system suitable for stepped independent foundations of different widths; and the horizontal and vertical frames as well as the frame connecting columns are all connected by bolts or screws, making the formwork reinforcement device easier to erect and dismantle, and convenient for reuse.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 As shown in Embodiment 1 of this utility model, a large-section stepped independent foundation template reinforcement device includes at least two layers of frame system 1. The number of layers of frame system 1 can be set according to the number of steps on the stepped independent foundation; one layer of frame system 1 is required for each step. Except for the bottom frame system 1, which is set on the ground, the other layers of frame system 1 are successively set on the frame system 1 of the next lower step, with the lower step's frame system 1 supporting the upper layer's frame system 1. In this embodiment, two layers of frame system 1 are provided to form a two-step stepped independent foundation, and the upper frame system is supported on top of the lower frame system, i.e., the upper frame system is erected on the lower frame system. The inner side of the frame system 1 has a U-shaped groove 4 for inserting the template 3 for installation. The outer side of the frame system 1 is connected to a diagonal bracing system 2 for supporting and reinforcing the template of the stepped independent foundation. In this embodiment, as shown... Figure 3 As shown, the lower frame system is connected to the diagonal bracing system 2 on the outside.

[0032] Furthermore, such as Figure 1 and Figure 5 As shown, the diagonal bracing system 2 includes a frame connecting column 21 and diagonal bracing assemblies hinged to the frame connecting column 21. The frame connecting column 21 is used to connect to the lower frame system. The diagonal bracing assemblies are supported on the ground to support the lower frame system.

[0033] Furthermore, such as Figure 5As shown, the diagonal bracing assembly includes a diagonal brace 22 hinged to the frame connecting column 21 and an anchor rod 23 disposed at the other end of the diagonal brace 22. A hinge seat 212 is provided on the outer side of the frame connecting column 21. A hinge shaft passes through the upper end of the diagonal brace 22, the hinge shaft is horizontally positioned, and both ends of the hinge shaft pass through the hinge seat 212. The upper end of the diagonal brace 22 is rotatably connected to the hinge shaft and / or the hinge shaft is rotatably connected to the hinge seat 212, allowing the diagonal brace 22 to be rotated to adjust its angle.

[0034] Furthermore, such as Figure 5 As shown, the lower end of the diagonal brace 22 is provided with an insert plate 221, and the anchor rod 23 is inserted into the ground after being connected to the insert plate 221. In one embodiment, the insert plate 221 can be fixed at the lower end of the diagonal brace 22. The insert plate 221 is provided with an insertion hole, and the anchor rod 23 is a cone shape that is larger at the top and smaller at the bottom. The anchor rod 23 is a cone or a pyramid with a regular polygonal cross-section, and the insertion hole is a corresponding circular hole or a regular polygonal hole. At the same time, the diameter of the circular hole or the side length of the regular polygonal hole is smaller than the diameter or side length of the top cross-section of the anchor rod 23, so that the anchor rod 23 passes through the insertion hole and is inserted into the ground, which can anchor the insert plate 221 and the diagonal brace 22, thereby making the diagonal brace system 2 stably support the skeleton system. In another embodiment, the insert plate 221 can be hinged to the lower end of the diagonal brace 22, and the hinge method can be the same as the hinge method between the upper end of the diagonal brace 22 and the frame connecting column 21; the anchor rod 23 can be fixedly connected to the insert plate 221, or the insert plate 221 can be provided with a hole, and the hole is larger than the lower end of the anchor rod 23 and smaller than the upper end of the anchor rod 23, so that the anchor rod 23 passes through the hole and is inserted into the ground to anchor the diagonal brace system.

[0035] Example 2 differs from Example 1 in that, as Figure 1 As shown, both the upper and lower skeleton systems include an upper skeleton and a lower skeleton, and the upper and lower skeletons of each skeleton system are connected by skeleton connecting columns 21 to form a skeleton system.

[0036] Furthermore, in this embodiment, as Figure 1 and Figure 3 As shown, the skeleton system is a rectangular skeleton system. Both the upper and lower skeletons include at least two horizontally arranged transverse skeletons 1A and at least two horizontally arranged longitudinal skeletons 1B. In this embodiment, both the upper and lower skeletons include two horizontally arranged transverse skeletons 1A and two horizontally arranged longitudinal skeletons 1B. Furthermore, the two transverse skeletons 1A of the upper skeleton are parallel and spaced apart, and the two longitudinal skeletons 1B are parallel and spaced apart. The two transverse skeletons 1A and the two longitudinal skeletons 1B are vertically connected to form a rectangular frame structure for the upper skeleton. Similarly, the two transverse skeletons 1A and the two longitudinal skeletons 1B of the lower skeleton are parallel and spaced apart, and the two transverse skeletons 1A and the two longitudinal skeletons 1B are vertically connected to form a rectangular frame structure for the lower skeleton. Both the transverse skeletons 1A and the longitudinal skeletons 1B have multiple perforations. Figure 3 and Figure 4 As shown, at the intersection of the transverse frame 1A and the longitudinal frame 1B, one of the transverse frame 1A and the longitudinal frame 1B is placed on top of the other, aligning their through holes. A connecting screw 15 is then passed through the through holes and a nut is tightened, connecting the transverse frame 1A and the longitudinal frame 1B. The upper and lower frames of each layer of the frame system are then connected by frame connecting columns 21 to form a rectangular frame system.

[0037] When only the lower frame system is equipped with a diagonal bracing system, the upper and lower frames of the upper frame system can still be connected by the frame connecting column 21.

[0038] Example 3 differs from Example 2 in that, in this example, as Figure 4 and Figure 6 As shown, the U-shaped groove 4 is set on the lower frame of each layer of the skeleton system, that is, on the horizontal frame 1A and the vertical frame 1B of the lower frame, and the opening of the U-shaped groove faces upward to facilitate the placement of the template 3. In another embodiment, the U-shaped groove 4 can be set on both the lower frame and the upper frame of each layer of the skeleton system, that is, the opening of the U-shaped groove of the lower frame faces upward and the opening of the U-shaped groove of the upper frame faces downward, which can better hold the template; in the construction of this embodiment, the lower frame and template need to be assembled first before the upper frame can be assembled, and then the skeleton connecting columns can be assembled; alternatively, the three sides of the rectangular skeleton system can be assembled by first assembling the upper frame, the lower frame and the skeleton connecting columns and then assembling the template, leaving the last side to be assembled by first assembling the lower frame and the template before assembling the upper frame, and then assembling the skeleton connecting columns of that side.

[0039] Furthermore, since the horizontal skeleton 1A and the vertical skeleton 1B of the upper and lower skeletons are both overlapping, in the overlapping horizontal skeleton 1A and vertical skeleton 1B of the lower skeleton, the bottom of the U-shaped groove connected to the lower horizontal skeleton 1A or vertical skeleton 1B can be aligned with the bottom of the horizontal skeleton 1A or vertical skeleton 1B; the bottom of the U-shaped groove connected to the upper vertical skeleton 1B or horizontal skeleton 1A is lower than the vertical skeleton 1B or horizontal skeleton 1A and is flush with the bottom of the U-shaped groove on the lower horizontal skeleton 1A or vertical skeleton 1B.

[0040] When the upper frame is provided with a U-shaped groove with the opening facing downward, the bottom of the U-shaped groove connected to the upper horizontal frame 1A or vertical frame 1B can be aligned with the top of the horizontal frame 1A or vertical frame 1B; the bottom of the U-shaped groove connected to the lower vertical frame 1B or horizontal frame 1A in the upper frame is higher than the vertical frame 1B or horizontal frame 1A and is flush with the bottom of the U-shaped groove on the upper horizontal frame 1A or vertical frame 1B.

[0041] In another preferred embodiment, the downward-facing U-shaped groove on the upper frame can also be provided at the upper end of the frame connecting column 21.

[0042] Example 4 differs from Example 2 in that, as Figure 5 As shown, the frame connecting column 21 includes a vertical column and transverse connecting members connected to the upper and lower ends of the vertical column. The transverse connecting members are located on the inner side of the frame connecting column 21 facing the frame system, that is, the side away from the diagonal brace. The upper and lower transverse connecting members overlap and connect with the transverse frame 1A or longitudinal frame 1B of the upper and lower frames, respectively. That is, the upper transverse connecting member is used to connect to the upper frame, and the lower transverse connecting member is used to connect to the lower frame. In the specific connection process, the upper transverse connecting member overlaps and connects with the transverse frame 1A or longitudinal frame 1B of the upper frame, and the lower transverse connecting member overlaps and connects with the transverse frame 1A or longitudinal frame 1B of the lower frame. In this embodiment, frame connecting columns 21 are provided on all four sides of the frame system. Therefore, some of the transverse connecting members of the frame connecting columns 21 overlap and connect with the transverse frame 1A, and other parts of the transverse connecting members of the frame connecting columns 21 overlap and connect with the longitudinal frame 1B.

[0043] Furthermore, such as Figure 5 As shown, the upper and lower transverse connectors are respectively provided with column connection holes, and the transverse skeleton 1A and the longitudinal skeleton 1B are respectively provided with corresponding skeleton connection holes. The connecting screws 15 are inserted into the column connection holes and the corresponding skeleton connection holes, and after connecting the nuts, the transverse connectors are fixedly connected to the corresponding transverse skeleton 1A or longitudinal skeleton 1B.

[0044] In another preferred embodiment, a U-shaped groove with an opening facing downwards can be provided at the inner end of the upper transverse connector for clamping the template.

[0045] Furthermore, the lower frame of the upper skeleton system has a relatively long horizontal frame 1A or vertical frame 1B, extending to overlap the upper frame of the lower skeleton system's vertical frame 1B or horizontal frame 1A. There are also skeleton connection holes at the overlap point, allowing the upper and lower skeleton systems to be connected and fixed by passing through connecting screws 15 and connecting nuts. Multiple through holes can be sequentially provided in the horizontal frame 1A or vertical frame 1B as the skeleton connection holes.

[0046] Example 5 differs from Example 3 in that, as Figure 1 As shown, both the transverse frame 1A and the longitudinal frame 1B of the skeleton system are rectangular steel. Figure 5As shown, all the transverse connecting members are short square steel. When the transverse frame 1A overlaps with the longitudinal frame 1B, and when the transverse connecting member overlaps with the transverse frame 1A or the longitudinal frame 1B, the outer surfaces of the long square steel abut against each other, and the outer surfaces of the long square steel abut against the short square steel. This surface-to-surface contact increases the contact area, making the frame system more stable.

[0047] Furthermore, both the transverse frame 1A and the longitudinal frame 1B include an inner square steel 11 and an outer square steel 12 sleeved on the outside of the inner square steel 11. The inner square steel 11 and the outer square steel 12 are slidably fitted together, and the inner square steel 11 and the outer square steel 12 are provided with multiple corresponding through holes 14 for inserting locking bolts 13. After tightening the nuts, the transverse frame 1A or the longitudinal frame 1B after length adjustment is fixed. The through holes 14 are equidistantly arranged on the inner square steel 11 and the outer square steel 12 along the length direction of the square steel.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
