Description

Technical Field

[0001] This utility model relates to an integrated trestle, and more particularly to an integrated trestle for precisely controlling cast-in-place concrete slabs. Background Technology

[0002] In recent years, in-depth research and long-term practical analysis have revealed that dimensional deviations in floor slab structures during construction, particularly errors in slab thickness and flatness, as well as the thickness of the concrete cover for reinforcing bars, have become key factors affecting the quality of floor slab structures. These issues not only relate to the initial quality of the building project but also directly impact its durability and aesthetics. Traditional construction methods have many shortcomings in controlling the dimensional accuracy of floor slab structures. For example, different slab sizes require a wide variety of matching stirrups, making on-site adjustments complex. Furthermore, both strip stirrups and point-supported stirrups lack stability, resulting in insufficient stiffness of the reinforcing bars, making them susceptible to damage during construction and affecting the finished product's protective effect. In addition, substandard concrete cover after pouring can easily lead to cracks and other defects, causing significant difficulties for later repairs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an integrated stirrup for precise control of cast-in-place concrete slabs. It can be effectively adjusted and has stability. It can achieve integrated control of multiple functions such as the thickness of the protective layer of the upper and lower steel bars, the thickness of the floor slab, the flatness of the floor slab, and the elevation of the slab surface. It greatly simplifies the control process, controls the flatness of the floor slab more precisely, reduces construction costs, and improves economic efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An integrated support trestle for precise control of cast-in-place concrete slabs includes an upper support plate and a lower support plate. The upper and lower support plates have the same structure and both include threaded sleeves. The threaded sleeves are fixedly connected to a ring through a circumferential connecting rod. The threaded sleeves of both the upper and lower support plates are threadedly connected to a screw rod.

[0006] The lower end of the ring of the lower support plate is fixed with a support foot.

[0007] The screw tip is threaded with an elevation control nut.

[0008] Both the upper and lower support plates are made of steel bars.

[0009] The support legs are at least three sets.

[0010] The screw has a bottom support at its lower end.

[0011] The base support consists of multiple support rods arranged circumferentially, with one end of each support rod fixedly connected to a screw and the other end extending horizontally outward.

[0012] This utility model provides an integrated stirrup for precise control of cast-in-place concrete slabs, which has the following technical advantages:

[0013] 1) The upper and lower support plates are threadedly connected to the screw rod, and the support legs are threadedly connected to the lower support plate, allowing for flexible height adjustment to meet the needs of various floor slab thicknesses and precisely control the protective layer thickness of main reinforcement bars of different specifications. This design cleverly adapts to the combination of different slab thicknesses and various reinforcement specifications in existing projects, making it applicable to floor slabs with thicknesses ranging from 100 to 250 mm. This support bar effectively replaces traditional spacers, upper rubber reinforcement support bars, and elevation control points, achieving integrated control of multiple functions such as the protective layer thickness of upper and lower reinforcement bars, floor slab thickness, floor slab flatness, and slab elevation, greatly simplifying the control process.

[0014] 2) The adjustable-height elevation control nut, with its upper end serving as the leveling control point for the leveling layer, allows for more precise control over the flatness of the floor slab. Furthermore, the two discs on the stirrups effectively increase the load-bearing area, improving the overall bending resistance of the floor slab reinforcement. This not only better protects the floor slab reinforcement from deformation caused by inspections or workers stepping on it, but also solves the problem of exposed reinforcement in the floor slab due to improper operation or insufficient protection, fully meeting the requirements for finished product protection.

[0015] 3) The integrated trestles use materials commonly used on construction sites, including recycled waste materials. This design not only achieves waste recycling and meets environmental protection requirements, but also reduces construction costs and improves economic efficiency. Attached Figure Description

[0024] Example 1

[0025] like Figure 1-4 As shown, an integrated support plate for precisely controlling cast-in-place concrete slabs includes an upper support plate 1 and a lower support plate 2. The upper support plate 1 supports the main reinforcing bars 10 of the upper steel reinforcement layer, and the lower support plate 2 supports the main reinforcing bars 10 of the lower steel reinforcement layer. The upper support plate 1 and the lower support plate 2 have the same structure, both including threaded sleeves 3. The threaded sleeves 3 are fixedly connected to a ring 5 via multiple circumferential connecting rods 4. The threaded sleeves 3 of both the upper support plate 1 and the lower support plate 2 are threadedly connected to a screw rod 6. In this way, the upper support plate 1 and the lower support plate 2 can move up and down relative to the screw rod 6.

[0026] This device is placed on the end face 11 of the template, one per 3-4 square meters.

[0027] like Figure 1-2 As shown, the lower end of the ring 5 of the lower support plate 2 is threaded with a support leg 7. The support leg 7 rests on the lower template end face 11 and supports the device. At the same time, after the support leg 7 rotates relative to the lower support plate 2, the height of the lower support plate 2 relative to the lower template end face 11 is adjustable.

[0028] The top of the screw 6 is threadedly connected to an elevation control nut 8. The upper end of the elevation control nut 8 can serve as a control point for the leveling layer 13, enabling precise control over the flatness of the floor slab.

[0029] Both the upper support plate 1 and the lower support plate 2 are made of steel bars. The steel bars can be made from on-site waste materials, thereby realizing waste recycling and reducing costs.

[0030] The main body of the upper support plate 1 and the lower support plate 2 is made of steel bars and is disc-shaped, which can increase the stress area. When supporting and reinforcing the main reinforcement 10, it can improve the bearing capacity of the support and enhance the overall stability of the floor slab reinforcement.

[0031] The construction process is as follows:

[0032] 1) such as Figure 4As shown, the distance from the main reinforcement 10 of the lower reinforcement layer to the end face 11 of the formwork is H, where H is the thickness of the concrete cover of the lower reinforcement layer; the distance from the main reinforcement 10 of the upper reinforcement layer to the upper end face of the initial concrete layer 12 is H1, where H1 is the thickness of the concrete cover of the upper reinforcement layer.

[0033] The lower support plate 2 is used to support the main reinforcement 10 of the lower steel layer. After the support leg 7 is screwed relative to the lower support plate 2, the height of the lower support plate 2 and the end face 11 of the template can be adjusted, thereby adjusting the height position of the main reinforcement 10 of the lower steel layer, and thus adjusting the thickness of the lower steel protective layer.

[0034] Similarly, the upper support plate 1 is used to support the main reinforcement 10 of the upper steel layer. By rotating the upper support plate 1, the upper support plate 1 moves up and down relative to the screw 6, thereby adjusting the height position of the main reinforcement 10 of the upper steel layer, and thus adjusting the thickness of the upper steel protective layer.

[0035] 2) After determining the thickness of the upper and lower reinforcing bar protective layers, determine the thickness of the initial concrete layer 12 according to different floor slab thicknesses. Rotate the elevation control nut 8 so that the upper end of the elevation control nut 8 is flush with the designed upper surface of the initial concrete layer 12. This ensures that the thickness of the floor slab after later pouring meets the requirements. At the same time, the upper end of the elevation control nut 8 serves as the base surface of the leveling layer 13, controlling the leveling of the concrete surface and precisely controlling the thickness and flatness of cast-in-place concrete slabs of different thicknesses.

[0036] Example 2

[0037] like Figure 5-6 As shown, unlike Embodiment 1, the lower end of the screw 6 is lower than the lower support plate 2, and the lower end of the screw 6 is fixed to the bottom support 9. The bottom support 9 uses multiple support rods arranged circumferentially and extending horizontally outward.

[0038] When it is necessary to adjust the thickness of the upper and lower reinforcing bar protective layers, simply rotate the upper support plate 1 and the lower support plate 2 to adjust the position of the upper and lower main reinforcing bars 10, thereby adjusting the thickness of the upper and lower reinforcing bar protective layers. This is simpler, more convenient, and provides more stable support compared to adjusting the support feet 7.
