Description

Technical Field

[0001] The present application relates to the field of pier column form turnover construction, and in particular to a formwork for pier column form turnover construction with four-sided variable slope and round chamfers. Background Art

[0002] At present, pier column form turnover construction is a technology widely used in the construction of high piers of bridges. Through special formwork and lifting systems, the concrete pier body can be poured in a vertical state.

[0003] The existing pier column form turnover construction method adopts multi-layer formwork technology. Specifically, when the construction of the lower pier column is completed, the formwork of the lower layer is lifted to the upper layer for continuous construction of the pier column. In this process, formwork with round chamfers on all sides needs to be prefabricated before use.

[0004] The above existing technical solutions have the following defects: When using formwork with round chamfers for construction, due to the need to meet the requirements of pier columns with different lengths and widths, it is necessary to fabricate various forms of construction molds with round chamfers. This approach not only wastes materials but also increases the overall cost of pier column form turnover construction. Utility Model Content

[0005] In order to adapt to the construction requirements of pier columns with different lengths and widths and reduce costs, the present application provides a formwork for pier column form turnover construction with four-sided variable slope and round chamfers.

[0006] The above technical objectives of the present application are achieved through the following technical solutions:

[0007] A formwork for pier column form turnover construction with four-sided variable slope and round chamfers includes straight plates, curved plates, fixing components, and mounting rods. The straight plates are arranged vertically, the curved plates are arranged on one side of the straight plates, the fixing components are arranged on the surfaces of the straight plates, the mounting rods are fixedly connected to the curved plates, and the mounting rods can be inserted into the fixing components. The straight plates and the curved plates are installed and fixed through the fixing components and the mounting rods. One curved plate and one straight plate form a unit, and one layer of construction formwork includes four units. The four units form a formwork for pier column form turnover construction with round chamfers.

[0008] By adopting the above technical solutions, through the setting of straight plates, curved plates, and fixing components, the straight plates and the curved plates can be quickly assembled and fixed, and the positioning and installation between the upper and lower layer formworks can be quickly carried out during form turnover, improving the quality of pier column construction. One straight plate and one curved plate form a unit. When facing the construction requirements of pier columns with different lengths and widths, straight plates with different lengths can be used to form the form turnover construction formwork, facilitating adaptation to the construction requirements of pier columns with different lengths and widths and improving the installation efficiency.

[0009] Optionally, the fixing component includes a fixing sleeve and a fixing post. The fixing sleeve is arranged on one side of the straight plate, and the fixing post is arranged above the end of the fixing sleeve. The mounting rod can be inserted into the fixing sleeve. Fixing holes are formed in the peripheral wall of the fixing sleeve, and mounting holes are formed in the peripheral wall of the mounting rod. The fixing post can be inserted into the fixing hole and the mounting hole simultaneously.

[0010] By adopting the above technical solution, when the side wall of the curved plate is attached to the end face of the straight plate, the mounting rod is inserted into the fixing sleeve, the hole walls of the fixing holes are flush with the hole walls of the mounting holes, and the fixing post is inserted into the fixing hole and the mounting hole to fix the mounting rod in the fixing sleeve, so that a straight plate and a curved plate can be quickly combined into a unit, improving the installation efficiency and facilitating the adaptation to the construction requirements of pier columns with different lengths and widths.

[0011] Optionally, the fixing component further includes a fixing member, which is arranged on the straight plate surface, and the fixing sleeve is inserted into the fixing member.

[0012] By adopting the above technical solution, by arranging the fixing member to set the fixing sleeve on the straight plate surface, the connection strength between the fixing sleeve and the straight plate can be strengthened compared with the case where the fixing sleeve is fixedly connected to the straight plate surface.

[0013] Optionally, the fixing component further includes a hinge post, which is hinged on the surface of the fixing member, and the fixing post is arranged on the peripheral wall of the hinge post.

[0014] By adopting the above technical solution, by arranging the hinge post, it can be avoided that when the straight plate and the curved plate are disassembled during the form turnover, it is necessary to hold the fixing post by hand.

[0015] Optionally, the end of the mounting rod is processed into a spherical surface.

[0016] By adopting the above technical solution, the spherical surface can make the mounting rod more convenient and fast to be inserted into the fixing sleeve.

[0017] Optionally, both the fixing post and the mounting hole are bent.

[0018] By adopting the above technical solution, the bent fixing post and mounting hole can make the fixing post more quickly inserted into the mounting hole and the fixing hole to fix the mounting rod.

[0019] Optionally, a protruding positioning member and a recessed positioning member are fixedly connected to the straight plate surface. A protruding arc surface is formed on the side wall of the protruding positioning member, and a positioning groove is formed on the side wall of the recessed positioning member. The protruding arc surface can be inserted into the positioning groove.

[0020] By adopting the above technical solution, by setting the protruding positioning member and the concave positioning member, the upper and lower layer formworks can be quickly positioned and installed during the form turnover construction, improving work efficiency, enhancing the quality of pier column form turnover construction, and reducing the generation of casting gaps in the pier column.

[0021] Optionally, a chamfer with a curvature is formed on the upper side wall of the straight plate, and a concave curved surface is formed on the lower side wall of the straight plate.

[0022] By adopting the above technical solution, in cooperation with the protruding positioning member and the concave positioning member, the upper and lower layer formworks can be quickly positioned and installed during the form turnover construction, improving work efficiency

Detailed implementation mode

[0031] The following further describes the present application in detail with reference to the accompanying drawings.

[0032] An embodiment of the present application discloses a formwork for the construction of a pier column turnover form with circular chamfers at four sides. Referring to Figure 1 , the construction formwork includes a straight plate 1 and a curved plate 2. The straight plate 1 and the curved plate 2 are combined to form a turnover formwork for construction with circular chamfers at the four corners. The straight plate 1 and the curved plate 2 can be quickly assembled and fixed, and can be quickly positioned and installed between the upper and lower layer formworks during form turnover, improving the quality of pier column construction. The combination of the straight plate 1 and the curved plate 2 can adapt to the construction of pier columns with different lengths and widths.

[0033] Combined with Figure 1 and Figure 2 , the straight plate 1 is in the shape of a strip plate, the straight plate 1 is vertically arranged, and the length direction of the straight plate 1 is horizontal. The straight plate 1 is provided with a protruding positioning member 11 and a recessed positioning member 12. The protruding positioning member 11 is arranged at the upper part of the plate surface of the straight plate 1. The protruding positioning member 11 is a square column, and the length direction of the protruding positioning member 11 is parallel to the length direction of the straight plate 1. The side wall of the protruding positioning member 11 is processed to form a protruding arc surface 111, and the height of the protruding arc surface 111 is higher than the height of the upper side wall of the straight plate 1. The recessed positioning member 12 is arranged at the lower part of the plate surface of the straight plate 1. The recessed positioning member 12 and the protruding positioning member 11 are located on the same side plate surface of the straight plate 1. The recessed positioning member 12 is a square column, and the length direction of the recessed positioning member 12 is parallel to the length direction of the straight plate 1. The lower side wall of the recessed positioning member 12 is flush with the lower side wall of the straight plate 1, and a positioning groove 121 is opened on the lower side wall of the recessed positioning member 12. The length direction of the positioning groove 121 is parallel to the length direction of the recessed positioning member 12.

[0034] Combined with Figure 1 and Figure 2 , during the construction of the pier column turnover form, after the lower layer of the pier column is poured, the lower layer formwork needs to be moved to the upper part. By setting multiple layers of formworks, the cost can be saved and the efficiency can be improved. Each layer of formwork includes multiple straight plates 1 and curved plates 2. Between adjacent two layers of formworks, the protruding arc surface 111 of the lower layer straight plate 1 is adapted to the positioning groove 121 of the corresponding position straight plate 1 of the upper layer, and the protruding arc surface 111 can be inserted into the positioning groove 121. Between different straight plates 1, when the protruding arc surface 111 of the lower layer straight plate 1 fits against the groove wall of the positioning groove 121 of the upper layer straight plate 1, the opposite side walls of the two straight plates 1 fit, which can improve the quality of pier column construction and reduce the generation of casting gaps in the pier column. The upper side wall of the straight plate 1 is processed to form a chamfer with a curvature, and the lower side wall of the straight plate 1 is processed to form a recessed curved surface. The chamfer of one of the two straight plates 1 can fit against the recessed curved surface of the other straight plate 1. Cooperating with the protruding positioning member 11 and the recessed positioning member 12 can quickly position and install the upper and lower layer formworks during form turnover construction, improving the work efficiency.

[0035] Combined with Figure 1 and Figure 2 , the curved plate 2 is arranged on one side of the straight plate 1. The surface of the curved plate 2 is bent into an arc surface along the length direction. The length direction of the curved plate 2 is vertically arranged. The side wall of the curved plate 2 is attached to the end face of the straight plate 1. One straight plate 1 and one curved plate 2 form a unit of the formwork for the construction of pier turnover forms. One layer of formwork is composed of four units. The end face of the straight plate 1 of one unit away from the curved plate 2 is attached to the side wall of the curved plate 2 of another unit away from the straight plate 1. The four units form a formwork for the construction of pier turnover forms with round chamfers at the four corners. When facing the construction requirements of piers with different lengths and widths, straight plates 1 with different lengths can be used to form the formwork for turnover form construction, with strong adaptability.

[0036] Combined with Figure 1 and Figure 3 , two groups of fixing components 13 are arranged on the surface of the straight plate 1 in one unit. The fixing components 13 are arranged between the protruding positioning members 11 and the recessed positioning members 12. One group of fixing components 13 includes a fixing member 131 and a fixing sleeve 132. The fixing member 131 is arranged at one end of the straight plate 1 close to the curved plate 2 on the surface of the straight plate 1. The fixing member 131 is a square block. The length direction of the fixing member 131 is perpendicular to the length direction of the straight plate 1. The side wall of the fixing member 131 is fixedly connected to the surface of the straight plate 1. There are two fixing members 131, and the length directions of the two fixing members 131 are parallel and spaced. A receiving hole is formed on the surface of the fixing member 131. The receiving hole communicates with two opposite surfaces of the fixing member 131. The outer peripheral wall of the fixing sleeve 132 is adapted to the receiving hole and the fixing sleeve 132 is inserted into the receiving hole. The length direction of the fixing sleeve 132 is parallel to the length direction of the straight plate 1. A fixing hole 133 is formed on the peripheral wall of the fixing sleeve 132 away from the curved plate 2. The fixing hole 133 communicates with the inside and outside of the fixing sleeve 132.

[0037] Combined with Figure 1 and Figure 3 , the fixing component 13 further includes a hinge column 134 and a fixing column 135. The hinge column 134 is hinged on the surface of the fixing member 131 away from the curved plate 2. The hinge column 134 is located above the fixing sleeve 132. The length direction of the hinge column 134 is always parallel to the surface of the straight plate 1. The fixing column 135 is arranged on the peripheral wall of the hinge column 134. The fixing column 135 is a curved cylinder. The fixing column 135 is adapted to the fixing hole 133 and the fixing column 135 can be inserted into the fixing hole 133.

[0038] Combined with Figure 1 and Figure 3, on the plate surface of the curved plate 2 in a unit, there is a mounting rod 21. The end of the peripheral wall of the mounting rod 21 is fixedly connected to one end of the plate surface of the curved plate 2 close to the straight plate 1. The length direction of the mounting rod 21 is perpendicular to the length direction of the curved plate 2. The mounting rod 21 is adapted to the fixed sleeve 132 and can be inserted into the fixed sleeve 132. The end face of the mounting rod 21 away from the curved plate 2 is processed into a spherical surface, which can make the mounting rod 21 more convenient and rapid to be inserted into the fixed sleeve 132. An installation hole 22 is opened on the peripheral wall of the mounting rod 21 away from the curved plate 2. The installation hole 22 is adapted to the fixed column 135 and the fixed column 135 can be inserted into the installation hole 22.

[0039] Combined Figure 1 with Figure 3 , when the side wall of the curved plate 2 is attached to the end face of the straight plate 1, the mounting rod 21 is inserted into the fixed sleeve 132, and the hole walls of the fixing hole 133 and the installation hole 22 are flush. Rotate the hinge column 134 to insert the fixed column 135 into the fixing hole 133 and the installation hole 22, and fix the mounting rod 21 in the fixed sleeve 132, so as to quickly form a unit by one straight plate 1 and one curved plate 2, improve the installation efficiency, and facilitate adapting to the construction requirements of pier columns with different lengths and widths.
