Abstract
Description
Technical Field
[0001] The present application relates to the technical field of concrete walls, and in particular to an extra-long concrete wall structure. Background Art
[0002] In engineering construction, the application of extra-long concrete wall structures has become very common. Extra-long generally refers to a length of more than 35 meters, such as underground garages, outer walls of large underground buildings, side walls of various liquid storage tanks, and side walls of extra-long rivers.
[0003] At present, in order to reduce the occurrence of cracks, methods such as setting expansion joints and construction joints are usually adopted, but these methods not only increase the difficulty of construction, but may also reduce the overall performance of the wall. Utility Model Content
[0004] The utility model aims to solve or at least alleviate the problem that the prior art reduces cracks in super-long concrete walls by setting expansion joints, construction joints and the like, but setting construction joints and expansion joints will reduce the overall performance of the wall.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An extra-long concrete wall structure comprises an extra-long concrete wall composed of multiple sections of cement walls, wherein the multiple sections of cement walls are all embedded with reinforcement structures, and each of the ends of two adjacent sections of cement walls close to each other is provided with a receiving groove, wherein the receiving groove is filled with a hollow rubber column with a rectangular frame structure, and the inner cavity of the hollow rubber column is provided with multiple groups of symmetrically arranged connecting steel bars, wherein two connecting steel bars in each group are located in a section of the inner cavity of the hollow rubber column and are bent toward each other to form a curved portion, and the connecting steel bars on both sides of the curved portion extend in opposite directions, penetrate through the side walls of the hollow rubber column, and are respectively embedded in the two cement walls.
[0007] By adopting the above technical solution, when using, the user first inserts the hollow rubber column into the receiving groove opened between the adjacent ends of the two cement walls, and then installs a plurality of connecting steel bars with a curved portion in the middle in the hollow rubber column, and extends the connecting steel bars on both sides of the curved portion into the inner cavities of the two cement walls on both sides, so as to connect the two adjacent cement walls to form a whole, thereby greatly improving the stability of the super-long concrete wall structure composed of multiple cement walls, and avoiding as much as possible the problem that the existing technology reduces the generation of cracks in the super-long concrete wall by setting expansion joints, construction joints, etc., but setting construction joints and expansion joints will reduce the overall performance of the wall.
[0008] Optionally, the reinforcement structure includes a plurality of longitudinal steel bars arranged along the height direction of the cement wall and a plurality of transverse steel bars arranged along the length direction of the cement wall.
[0009] By adopting the above technical solution, a plurality of longitudinal steel bars and a plurality of transverse steel bars are arranged to be embedded in the cement wall to form a mesh structure, thereby improving the deformation resistance of the cement wall.
[0010] Optionally, the intersection of the longitudinal reinforcement and the transverse reinforcement is tied with a wire tie.
[0011] By adopting the above technical solution, a tie wire is set to tie and fix the intersection of the longitudinal steel bars and the transverse steel bars, so as to avoid the problem that during the pouring of the cement wall, the transverse steel bars and the longitudinal steel bars are displaced by the impact of concrete, resulting in uneven distribution of the longitudinal steel bars and the transverse steel bars in the cement wall, affecting the deformation resistance of the cement wall.
[0012] Optionally, the middle sections of the side walls of the hollow rubber column on both sides parallel to the length direction of the cement wall extend outward to form an overlapping portion, and both sides of the overlapping portion are respectively fitted with adjacent ends of the two cement walls.
[0013] By adopting the above technical solution, hollow rubber columns are set to fill the receiving grooves opened at adjacent ends of the cement wall. At the same time, since the hollow rubber columns are made of flexible rubber material, when the cement walls on both sides expand and deform due to changes in temperature and humidity, the deformation of the hollow rubber columns can be squeezed to offset the internal stress between the cement walls, thereby avoiding cracking of the cement walls due to internal stress as much as possible.
[0014] Optionally, a deformation cavity is opened on both side walls of the hollow rubber column perpendicular to the length direction of the cement wall, and a plurality of rubber plates are arranged in the inner cavity of the deformation cavity, and both ends of the rubber plates are respectively bonded to the inner wall of the deformation cavity.
[0015] By adopting the above technical solution, a deformation cavity is set, so that after the cement walls on both sides expand due to changes in temperature and humidity, the hollow rubber column can be squeezed to shrink into the deformation cavity, thereby offsetting the internal stress between the cement walls.
[0016] Optionally, both ends of the connecting steel bar are welded with a limit head with a hemispherical structure, and the diameter of the limit head is larger than the diameter of the end of the connecting steel bar.
[0017] By adopting the above technical solution, limit heads with larger diameters are set at both ends of the connecting steel bars to increase the friction between the ends of the connecting steel bars and the cement wall, so as to avoid the connecting steel bars from falling off from the inside of the cement wall after being stressed.
[0018] Optionally, a structural column is formed by filling the inner cavity of a hollow rubber column connected to the sides of the steel bars with concrete.
[0019] By adopting the above technical solution, concrete is filled in the inner cavity of the hollow rubber column to form a structural column after the concrete slab is solidified. The structural column is formed by pouring between two adjacent cement walls, which greatly improves the stability of the cement wall connection.
[0020] Optionally, a protective cover with a triangular structure is provided on the bent portion, and buckles are fixedly connected to both ends of the protective cover, and the buckles are clamped on the outer surface of the connecting steel bar.
[0021] By adopting the above technical solution, a protective cover is set on the curved part to block the concrete used for pouring to form the structural column, so as to avoid the problem that the curved part cannot bend due to the limiting effect of the structural column after the structural column plate is fixed.
[0022] In summary, the beneficial effects of this application are as follows:
[0023] The present application coordinates the structures such as hollow rubber columns, deformation cavities, connecting steel bars and curved parts. The user first inserts the hollow rubber column into the accommodating groove opened between the adjacent ends of the two cement walls, and then installs multiple connecting steel bars with curved parts in the middle in the hollow rubber column, and extends the connecting steel bars on both sides of the curved parts into the inner cavities of the two cement walls on both sides, connecting the two adjacent cement walls to form a whole, thereby greatly improving the stability of the super-long concrete wall structure composed of multiple cement walls, and avoiding as much as possible the problem that the existing technology reduces the generation of cracks in the super-long concrete wall by setting expansion joints, construction joints, etc., but setting construction joints and expansion joints will reduce the overall performance of the wall.

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-4 This application is described in further detail.
[0030] See also Figure 1-3An extra-long concrete wall structure includes an extra-long concrete wall composed of multiple sections of cement wall 1, each of which is embedded with a reinforcement structure. Two adjacent sections of cement wall 1 are connected by the reinforcement structure to form an integral structure, thereby increasing the stability of the overall extra-long concrete wall structure.
[0031] A receiving groove is formed at the ends of two adjacent cement walls 1 that are close to each other. The receiving groove is filled with a hollow rubber column 5 with a rectangular frame structure.
[0032] A plurality of groups of symmetrically arranged connecting steel bars 9 are provided in the inner cavity of the hollow rubber column 5. Two connecting steel bars 9 in each group are located in a section of the inner cavity of the hollow rubber column 5 and are bent toward each other to form a curved portion 10. The connecting steel bars 9 on both sides of the curved portion 10 extend in opposite directions, penetrate the side walls of the hollow rubber column 5, and are respectively embedded in the two cement walls 1, connecting the adjacent cement walls 1 to form an integral structure.
[0033] Reference Figure 1 The reinforcement structure includes a plurality of longitudinal steel bars 2 arranged along the height direction of the cement wall 1 and a plurality of transverse steel bars 3 arranged along the length direction of the cement wall 1. The plurality of longitudinal steel bars 2 and the plurality of transverse steel bars 3 are arranged to be embedded in the cement wall 1 to form a mesh structure, thereby improving the anti-deformation performance of the cement wall 1.
[0034] Reference Figure 4 The intersection of the longitudinal reinforcement 2 and the transverse reinforcement 3 is tied with a tie wire 4. The tie wire 4 is provided to tie and fix the intersection of the longitudinal reinforcement 2 and the transverse reinforcement 3, so as to avoid the transverse reinforcement 3 and the longitudinal reinforcement 2 being displaced by the impact of concrete during the pouring of the cement wall 1, resulting in uneven distribution of the longitudinal reinforcement 2 and the transverse reinforcement 3 in the cement wall 1, and affecting the anti-deformation performance of the cement wall 1.
[0035] Reference Figure 2 The hollow rubber column 5 extends outwardly from the middle section of the side walls parallel to the length direction of the cement wall 1 to form a lap joint 6, and the two sides of the lap joint 6 are respectively fitted with the adjacent ends of the two cement walls 1. The hollow rubber column 5 is used to fill the receiving grooves opened at the adjacent ends of the cement walls 1. At the same time, since the hollow rubber column 5 is made of a flexible rubber material, when the cement walls 1 on both sides expand and deform due to changes in temperature and humidity, the deformation of the hollow rubber column 5 can be squeezed to offset the internal stress between the cement walls 1, thereby avoiding cracking of the cement walls 1 due to internal stress.
[0036] Reference Figure 1 The hollow rubber column 5 is provided with deformation chambers 7 on both sides of the sidewalls perpendicular to the length direction of the cement wall 1. A plurality of rubber plates 8 are provided in the inner cavity of the deformation chamber 7. The two ends of the rubber plates 8 are respectively bonded to the inner wall of the deformation chamber 7. The deformation chamber 7 is provided so that after the cement walls 1 on both sides expand due to temperature and humidity changes, the hollow rubber column 5 can be squeezed to shrink into the deformation chamber 7 to offset the internal stress between the cement walls 1.
[0037] Reference Figure 2 The two ends of the connecting steel bar 9 are welded with a hemispherical stopper 11, and the diameter of the stopper 11 is larger than the diameter of the end of the connecting steel bar 9. The stopper 11 with a larger diameter is arranged at both ends of the connecting steel bar 9 to increase the friction between the end of the connecting steel bar 9 and the cement wall 1, and to prevent the connecting steel bar 9 from falling off from the inside of the cement wall 1 after being stressed.
[0038] Reference Figure 1 The inner cavity of the hollow rubber column 5 connected to the side of the steel bar 9 is filled with concrete to form a structural column 14. The inner cavity of the hollow rubber column 5 is filled with concrete to form a structural column 14 after the concrete slab is solidified. The structural column 14 is formed by pouring between two adjacent cement walls 1, which greatly improves the stability of the connection between the cement walls 1.
[0039] Reference Figure 3 The curved portion 10 is provided with a triangular-shaped shield 12, and buckles 13 are fixedly connected at both ends of the shield 12, and the buckles 13 are clamped on the outer surface of the connecting steel bar 9. The shield 12 is provided on the curved portion 10 to block the concrete used for pouring the structural column 14, and to avoid the problem that the curved portion 10 cannot be bent due to the limiting effect of the structural column 14 after the structural column 14 is fixed.
[0040] The implementation principle of the present application is: when in use, the user first inserts the hollow rubber column 5 into the accommodating groove opened between the adjacent ends of the two cement walls 1, and then installs a plurality of connecting steel bars 9 with a curved portion 10 in the middle in the hollow rubber column 5, and extends the connecting steel bars 9 on both sides of the curved portion 10 into the inner cavities of the two cement walls 1 on both sides, connecting the two adjacent cement walls 1 to form a whole, thereby greatly improving the stability of the super-long concrete wall structure composed of multiple cement walls 1, and avoiding as much as possible the problem of reducing the generation of cracks in the super-long concrete wall by setting expansion joints, construction joints, etc. in the prior art, but setting construction joints and expansion joints will reduce the overall performance of the wall.
