Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction and relates to an integrally formed formwork for a sloped independent foundation. Background Technique

[0002] The sloped independent foundation is a commonly used foundation form, which consists of a bearing platform and a conical body with a certain slope, and is suitable for areas with relatively complex terrains, such as mountainous areas and hilly areas. In the design of the sloped independent foundation, in order to reduce costs, compared with the conventional rectangular cross-section independent foundation, the sloped independent foundation can save more concrete and reduce the amount of formwork used on the premise of meeting the foundation force requirements, so it is widely used. However, the construction of the sloped independent foundation is difficult, and the construction difficulty lies in that it is not easy to control the pouring quality of concrete when pouring the conical body.

[0003] At present, the existing sloped independent foundation construction often adopts a step-by-step construction method. First, the bearing platform concrete is poured, and then the conical body is poured several hours later. If the artificial slope stacking process is used to pour the conical body, since no formwork is installed, the concrete cannot be vibrated densely. If wooden formwork, steel formwork, etc. are used to pour the conical body, it is more difficult to vibrate and exhaust the concrete, and it is easy to cause defects such as air bubbles and honeycombs in the conical body, resulting in a reduction in the strength of the sloped independent foundation. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrally formed formwork for a sloped independent foundation, which can vibrate the concrete when pouring the conical body, and enable the gas in the concrete to be discharged normally, avoiding defects such as air bubbles and honeycombs in the built conical body, and improving the strength of the sloped independent foundation.

[0005] To achieve the above purpose, the specific technical solution of an integrally formed formwork for a sloped independent foundation provided by the utility model is as follows:

[0006] An integrally formed formwork for a sloped independent foundation includes:

[0007] A first formwork component for pouring the bearing platform. The first formwork component includes four first side plates, and the four first side plates are sequentially connected end to end to form a quadrilateral structure, and two adjacent first side plates are detachably connected;

[0008] A second formwork component is arranged on the upper part of the first formwork component. The second formwork component is used for pouring the conical body. The second formwork component includes:

[0009] Four steel bar frames, corresponding to the four first side plates one by one. Each steel bar frame is a trapezoidal structure, and the lower bottom edge of each steel bar frame is detachably connected to the corresponding first side plate, and the side edges of two adjacent steel bar frames are detachably connected;

[0010] Four groups of exhaust structures are arranged inside four steel bar frames and correspond to the four steel bar frames one by one. Each group of exhaust structures is connected to the corresponding steel bar frame, and each group of the exhaust structures is used to act as a template to prevent slurry leakage and provide an exhaust channel for the concrete at the same time.

[0011] The features of the present utility model also lie in:

[0012] Each group of exhaust structures is composed of at least two second side plates capable of exhausting gas or at least two mesh plates.

[0013] Both of the two second side plates are trapezoidal structures. The two second side plates are stacked in sequence on the inner side surface of the corresponding steel bar frame. There is a gap between the two second side plates. A plurality of exhaust through holes are evenly formed on each second side plate, and the plurality of exhaust through holes on the two second side plates are arranged staggeredly.

[0014] Each of the second side plates is made of a metal material.

[0015] Both of the two mesh plates are trapezoidal structures and are made of metal wire meshes. The two mesh plates are stacked in sequence on the inner side surface of the corresponding steel bar frame, and the distances between the lower bottom edges of the two mesh plates and the corresponding first side plate are different.

[0016] Each steel bar frame is composed of a trapezoidal frame, a plurality of cross bars and a plurality of longitudinal bars. The plurality of cross bars are arranged inside the trapezoidal frame and are evenly arranged along the height direction of the trapezoidal frame. The plurality of longitudinal bars are arranged inside the trapezoidal frame and are arranged along the length direction of the trapezoidal frame. The two ends of each cross bar are respectively connected to the trapezoidal frame. Each cross bar is sequentially connected to a plurality of longitudinal bars. The two ends of each longitudinal bar are respectively connected to the trapezoidal frame.

[0017] Each of the first side plates is a wooden formwork or a metal formwork.

[0018] Between adjacent two of the first side plates, between adjacent two steel bar frames, and between each first side plate and the corresponding steel bar frame, bolt connections are all adopted.

[0019] The integrated forming formwork for a sloping independent foundation of the present utility model has the following advantages:

[0020] First, through the cooperation of the four first side plates, the four steel bar frames and the four groups of exhaust structures, it is possible to provide an exhaust channel for the concrete while preventing slurry leakage, which can not only make the concrete vibrate compactly, avoid the collapse and flattening caused by vibrating the concrete, but also discharge the gas inside the concrete, avoid defects such as air bubbles and honeycombs in the building cone body, and improve the strength of the sloping independent foundation.

[0032] As Figure 1, Figure 2 , Figure 3 As shown in Figure 2 and Figure 3 , the utility model provides an integrally formed template for a sloping independent foundation, which includes a first template assembly 1 and a second template assembly 2. The first template assembly 1 is used for pouring the bearing platform. The first template assembly 1 includes four first side plates 101, and the four first side plates 101 are sequentially connected end to end to form a quadrilateral structure. Each first side plate 101 is vertically arranged, and two adjacent first side plates 101 are detachably connected, so that the four first side plates 101 form a quadrilateral box structure, which is convenient for pouring the bearing platform. The second template assembly 2 is arranged on the upper part of the first template assembly 1, and the second template assembly is used for pouring the conical body. The second template assembly 2 includes four steel bar frames 201 and four groups of exhaust structures. The four steel bar frames 201 correspond to the four first side plates 101 one by one. Each steel bar frame 201 is a trapezoidal structure, and the lower bottom edge of each steel bar frame 201 is detachably connected to the corresponding first side plate 101, and the side edges of two adjacent steel bar frames 201 are detachably connected, so that the four steel bar frames 201 form a conical structure and an opening is formed at the upper part, which is convenient for pouring the conical body. The four groups of exhaust structures are arranged inside the four steel bar frames 201, and the four groups of exhaust structures correspond to the four steel bar frames 201 one by one. Each group of exhaust structures is connected to the corresponding steel bar frame 201. Each group of exhaust structures is used to act as a template to prevent slurry leakage and provide an exhaust channel for the concrete, so that the concrete can be vibrated compactly, avoiding the collapse and flattening caused by vibrating the concrete, and the gas inside the concrete can be discharged, avoiding defects such as air bubbles and honeycombs in the built conical body, and improving the strength of the sloping independent foundation.

[0033] As Figure 2 , Figure 3 As shown in Figure 2 and Figure 3 , each group of exhaust structures is composed of at least two second side plates 202 capable of exhausting gas or at least two mesh plates 204, which is convenient for the gas in the concrete to be discharged from the second side plates 202 capable of exhausting gas or the mesh plates 204.

[0034] As Figure 2 , Figure 4 As shown in Figure 2 and Figure 4 , the two second side plates 202 are both trapezoidal structures. The two second side plates 202 are sequentially stacked on the inner side surface of the corresponding steel bar frame 201, and there is a gap between the two second side plates 202. A plurality of exhaust through holes 203 are uniformly formed on each second side plate 202, which is convenient for the gas in the concrete to be smoothly discharged. The plurality of exhaust through holes 203 on the two second side plates 202 are staggered, which is convenient to prevent the concrete from flowing out through the two second side plates 202. Each second side plate 202 is made of metal material.

[0035] As Figure 3 , Figure 5As shown, the two mesh plates 204 are trapezoidal in structure and made of wire mesh. The two mesh plates 204 are stacked in sequence on the inner side surfaces of the corresponding steel bar frames 201, enabling the gas in the concrete to be discharged smoothly. The distances between the lower bottom edges of the two mesh plates 204 and the corresponding first side plates 101 are different, causing the two mesh plates 204 to be staggered, which is convenient for preventing the concrete from flowing out. At the same time, through the two layers of wire mesh, the visualization of the concrete pouring process can be realized, facilitating the timely discovery of the situations occurring during the concrete pouring and vibration and enabling the timely handling of problems.

[0036] As Figure 2 , Figure 3 shown, each steel bar frame 201 is composed of a trapezoidal frame 2011, a plurality of cross bars 2012 and a plurality of longitudinal bars 2013. The plurality of cross bars 2012 are arranged inside the trapezoidal frame 2011 and evenly arranged along the height direction of the trapezoidal frame 2011. The plurality of longitudinal bars 2013 are arranged inside the trapezoidal frame 2011 and arranged along the length direction of the trapezoidal frame 2011. Both ends of each cross bar 2012 are respectively connected to the trapezoidal frame 2011. Each cross bar 2012 is sequentially connected to the plurality of longitudinal bars 2013. Both ends of each longitudinal bar 2013 are respectively connected to the trapezoidal frame 2011. Through the settings of the trapezoidal frame 2011, the plurality of cross bars 2012 and the plurality of longitudinal bars 2013, it is convenient to fix the two second side plates 202 or the two mesh plates 204 on the steel bar frame 201.

[0037] As Figure 1 shown, each first side plate 101 is a wooden formwork or a metal formwork. Adjacent two first side plates 101, adjacent two steel bar frames 201, and between each first side plate 101 and the corresponding steel bar frame 201 are all connected by bolts, which is convenient for quick installation and disassembly.

[0038] Working principle: During use, due to the large area of the bearing platform and the relatively small upper opening formed by the four first side plates 101, it is impossible to ensure that the concrete in the bearing platform is vibrated densely from the opening. Therefore, the bearing platform is poured first, and then the conical body is poured after a relatively short interval. First, at least two second side plates 202 or at least two mesh plates 204 are installed on the inner side of each steel bar frame 201. Then, the four first side plates 101 are connected end to end in sequence to form a quadrilateral box structure. Concrete is added between the four first side plates 101. After the bearing platform is poured, a steel bar frame 201 is immediately installed on the upper part of each first side plate 101, so that the lower bottom edge of the steel bar frame 201 is connected to the upper part of the corresponding first side plate 101, making at least two second side plates 202 or at least two mesh plates 204 installed on each steel bar frame 201 located inside the four steel bar frames 201. Then, the sides of two adjacent steel bar frames 201 are connected, and the concrete is poured into the four steel bar frames 201 from the upper openings of the four steel bar frames 201 for pouring the conical body. The pouring of the conical body can start after a relatively short interval. The interval time is the installation time of the second formwork assembly. After the conical body is poured, the four steel bar frames 201 are quickly disassembled and washed with high-pressure water for reuse. At the same time, after the four steel bar frames 201 are removed, the four concrete surfaces of the conical body need to be finished. Generally, an iron float can be used. If anti-corrosion, decoration and other work are also required on the concrete surface, a wooden float is preferably used to improve the surface roughness of the concrete.

[0039] The integrated forming formwork of a sloping independent foundation of the present utility model has the following advantages:

[0040] First, through the cooperation of the four first side plates, the four steel bar frames and the four groups of exhaust structures, it is possible to prevent slurry leakage while providing an exhaust channel for the concrete, enabling the concrete to be vibrated densely, avoiding the collapse and flattening caused by vibrating the concrete, and discharging the gas inside the concrete, avoiding defects such as air bubbles and honeycombs in the cast conical body, and improving the strength of the sloping independent foundation.

[0041] Second, through the cooperation of at least two layers of mesh plates and the corresponding steel bar frames, the visualization of the concrete pouring process can be realized, facilitating the timely discovery of the situation during the concrete pouring and vibration and enabling timely problem handling.

[0042] Third, through the detachable setting of the four steel bar frames and the four first side plates, it is convenient to quickly disassemble the four steel bar frames after the conical body is poured and wash them with high-pressure water, thus facilitating reuse and improving the use efficiency of the second formwork assembly.

[0043] Fourth, by pouring the conical body shortly after the pouring of the bearing platform is completed, the integral pouring of the bearing platform and the conical body can be realized, further improving the integrity of the sloped independent foundation.
