Description

Technical Field

[0001] This invention relates to the field of civil engineering construction technology, and in particular to a trestle with a water-stopping function. Background Technology

[0002] In the field of civil engineering construction, especially in the construction of foundation raft slabs, in order to ensure the accurate position of the upper layer of steel mesh and control the thickness of the steel protective layer, it is usually necessary to set up stirrups. Stirrups, also known as stirrup bars or bracing bars, are supporting components of the steel skeleton. Generally, the lower part of the stirrup is supported on the formwork or the lower layer of steel bars, and the upper part supports the upper layer of steel mesh, thereby ensuring the spacing of the double layer of steel bars and the overall stress performance.

[0003] However, in actual engineering projects, foundation raft slabs are often located below the groundwater level or within the area affected by seasonal groundwater. As reinforcing steel members that run through the entire thickness of the raft slab, the surface of the stirrups is difficult to completely seal with the concrete, easily forming tiny seepage channels. When the groundwater pressure is high, water will gradually seep upwards along the interface between the stirrup reinforcement and the concrete until it penetrates the raft slab, causing leakage in the basement floor. Currently, water seepage along the reinforcing steel is one of the common and difficult-to-cure quality defects in basement waterproofing projects.

[0004] Existing trestles typically only consider structural support and lack dedicated waterproofing features. To prevent leakage along the trestles, additional measures are often taken in engineering practice, such as welding a waterproof ring in the middle of the trestle or applying waterproof coating. However, these methods suffer from inconvenience in operation, inconsistent waterproofing effectiveness, and increased construction costs. Furthermore, the legs of traditional trestles are usually simple inverted V-shapes or straight lines, offering limited stability and anti-tipping capacity. They also often require additional concrete pads to control the thickness of the underlying steel reinforcement protective layer, further increasing material usage and construction procedures.

[0005] Therefore, there is an urgent need for a trestle structure that can stably support the steel mesh, effectively block the seepage path of groundwater, and simplify the protective layer control process to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a water-stopping trestle, addressing the problems of existing trestles which typically only consider structural support without dedicated water-stopping features. To prevent leakage along the trestles, additional measures are often required in engineering practice, leading to inconvenience, unstable water-stopping effects, and increased construction costs. Furthermore, traditional trestles have limited leg stability and anti-tipping capacity, and often require additional concrete pads to control the thickness of the underlying steel reinforcement cover, further increasing material usage and construction procedures. The preferred technical solutions provided by this invention offer numerous technical advantages, which are detailed below.

[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0035] As Figures 1-3 shown, the present invention provides a stool with a water stop function, including a stool main body 1, a water stop sheet 2 and stool legs 3. The stool main body 1 is a "U"-shaped space structure formed by bending steel bars; the water stop sheet 2 is fixedly connected to the vertical legs of the stool main body 1 for preventing groundwater from penetrating through the concrete slab along the stool; the stool legs 3 are arranged at the bottom of the stool main body 1 in an "M" shape, which stabilizes the stool while replacing traditional protective layer pads and reduces the usage amount of the pads.

[0036] For this stool with a water stop function, the stool main body 1 is set as a "U"-shaped space structure formed by bending steel bars. During use, the upper steel bars are supported by the "U"-shaped stool main body 1, and the water stop sheet 2 on the vertical legs of the stool main body 1 can effectively block the leakage path of groundwater upward along the steel bars. With the stool legs 3 arranged in an "M" shape and the stool legs 3 being arranged at the bottom of the stool main body 1, which stabilizes the stool while replacing traditional protective layer pads, the overall structure is simple and serves multiple purposes. At the same time, problems such as steel bar support, leakage prevention, and protective layer control are solved, improving the construction quality and efficiency of the foundation raft slab.

[0037] Specifically, as Figure 1 and Figure 4 shown, the stool main body 1 includes a cross beam 10, and a first vertical leg 11 and a second vertical leg 12 which are arranged at both ends of the cross beam 10 and perpendicular to the cross beam. The first vertical leg 11, the cross beam 10 and the second vertical leg 12 are arranged in sequence to form the "U"-shaped space structure. By setting the cross beam 10 perpendicular to the first vertical leg 11 and the second vertical leg 12, the vertical legs being perpendicular to the cross beam 10 can ensure vertical load transfer, improving the overall stiffness and stability of the stool. During use, it makes the upper steel bars placed more stably and the force is reasonable.

[0038] As Figure 5 shown, a first limiting groove 100 for accommodating steel bars is provided on the cross beam 10 in this embodiment. Specifically, by setting a slight depression in the middle of the cross beam 10, a circular arc-shaped first limiting groove 100 is formed for placing the upper steel bars and effectively limiting the upper steel bars, preventing the steel bars from rolling, sliding or shifting laterally during the concrete pouring process, ensuring the position accuracy and spacing uniformity of the upper steel bar mesh, and thus ensuring the mechanical properties of the structure.

[0039] As Figure 1 and Figure 6 As shown, the support leg 3 of the trestle includes a first leg 31 and a second leg 32. The first leg 31 is connected to the bottom of the first upright leg 11, and an arc-shaped groove is provided at the connection point. The second leg 32 is connected to the bottom of the second upright leg 12, and an arc-shaped groove is provided at the connection point. The arc-shaped groove at the connection point between the support leg and the upright leg can serve as a placement position or transition arc for the lower reinforcing bars, reducing stress concentration, facilitating the positioning of the reinforcing bars, improving the fit between the support leg and the lower reinforcing bars, and enhancing the overall stability of the trestle.

[0040] As an optional implementation, in this embodiment, the first leg 31 and the second leg 32 extend at a 90° angle to the crossbeam 10 and in opposite directions, increasing the contact span between the bottom of the stirrup and the formwork or lower layer of reinforcing steel, significantly improving the anti-tipping capacity, preventing the stirrup from tipping over during concrete impact or vibration, and ensuring the overall stability of the reinforcing steel skeleton. Figure 7 As shown, the middle of the first leg 31 and the second leg 32 is provided with an arc-shaped second limiting groove 300 for accommodating the reinforcing bars. In this embodiment, the middle of the first leg 31 and the second leg 32 is provided with a slight arc-shaped depression for placing the lower reinforcing bars of the reinforcing mesh, preventing the lower reinforcing bars from sliding or shifting, so that the trestle leg 3 can act as a reinforcing bar protective layer pad while preventing the reinforcing bars from sliding.

[0041] Optionally, the diameter of the reinforcing bar of the trestle leg 3 is the same as that of the reinforcing bar of the trestle body 1, and both are formed by continuously bending the same reinforcing bar. With this configuration, the overall structure of the trestle body 1 and the trestle leg 3 has no welding joints, resulting in higher strength and simpler manufacturing, thus avoiding the risk of the trestle leg 3 falling off during operation.

[0042] like Figure 8 As shown, the height of the trestle leg 3 is equal to the thickness of the protective layer of the applied concrete component. This ensures that the protective layer thickness of the lower reinforcement meets design requirements without the need for additional spacers, simplifying the construction process and avoiding protective layer deviations caused by spacer displacement or omissions.

[0043] As an optional implementation, the waterstop 2 is welded to the middle of the first support leg 11 and the second support leg 12. The middle section of the raft slab thickness is the core section of the groundwater seepage path. By welding the waterstop 2 to the middle of the first support leg 11 and the second support leg 12, the creeping distance of seepage water along the surface of the reinforcing steel is increased, and the capillary channels are cut off, effectively preventing groundwater from penetrating the concrete slab along the supports, thus solving the basement leakage problem at its root.

[0044] The waterstop in this embodiment is made of Q235 steel. Q235 steel has good weldability and a strong bond with the reinforcing steel, making it the preferred material for the waterstop 2 in this embodiment. The thickness of the waterstop is 1-3mm, preferably 2mm, balancing strength and weldability. The waterstop is a square with a side length of 5cm or a circle with a diameter of 5cm. The 5cm side length or diameter provides sufficient water-blocking area, and the standardized size facilitates factory prefabrication and on-site quality control, ensuring water-stopping effect while keeping costs under control and making construction convenient.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
