DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1 - Figure 4 The present application provides a corrugated pipe fixing device for prestressed construction, comprising:

[0038] A steel cage structure 100, wherein the steel cage structure 100 includes cross-distributed longitudinal steel bars 101 and transverse steel bars 102, and a space for installing a corrugated pipe 200 is reserved inside the steel cage structure 100;

[0039] A corrugated pipe member 200 installed inside the steel cage structure 100;

[0040] The positioning and mounting structure 300 is sleeved and mounted on the corrugated pipe fitting 200 and connected to the steel cage structure 100. The positioning and mounting structure 300 can realize the fastening and mounting of the corrugated pipe fitting 200 and the steel cage structure 100. In addition, within a certain range, even if there is a distance between the corrugated pipe fitting 200 and the steel bars, the universal reinforcing member 302 can be used to increase the mounting strength of the two. Compared with the traditional steel wire installation, it is more stable and will not deviate or shake due to concrete pouring, thereby increasing the accuracy of the pouring and processing position of the corrugated pipe fitting 200.

[0041] A side positioning member 400 for positioning the side of the corrugated pipe 200 is provided between the cross-distributed longitudinal steel bars 101 and the transverse steel bars 102. The side positioning member 400 can be used to limit the lateral position of the installed corrugated pipe 200, so that the installation position of the corrugated pipe 200 is more accurate, thereby improving the subsequent casting quality of the corrugated pipe 200;

[0042] The positioning and mounting structure 300 includes an annular mounting component 301 sleeved on the corrugated pipe 200 and two universal reinforcing components 302 mounted on the upper and lower surfaces of the annular mounting component 301 and connected to the steel cage structure 100 .

[0043] In the present embodiment, preferably, the annular mounting component 301 includes a second fixing ring 3011 and a first fixing ring 3012 which are relatively sleeved on the bellows 200, the second fixing ring 3011 and the first fixing ring 3012 form a circular structure sleeved on the bellows 200, and an annular groove 3016 is provided on the inner surface of the circular structure, the annular groove 3016 can be provided for the protrusion on the surface of the bellows 200 to be embedded when the circular structure is installed on the bellows 200, thereby increasing the mounting strength of the circular structure and the bellows 200 and preventing front and rear offset and misalignment from occurring, the second fixing ring 3011 and the first fixing ring 3012 are respectively provided with a second ear plate 3014 and a first ear plate 3013 at both ends, and the relatively distributed first ear plate 3013 and the second ear plate 3014 are connected by a plug-in component 3015.

[0044] In this embodiment, preferably, the plug-in component 3015 includes a plug-in column 30151 fixed on the upper surface of the first ear plate 3013. The plug-in component 3015 can reduce the trouble of rotating the bolts on the steel cage structure 100, increase the convenience of installing the second fixing ring 3011 and the first fixing ring 3012 and the corrugated pipe 200, and the plug-in column 30151 passes through the second ear plate 3014 and is exposed on the outside. The surface of the second ear plate 3014 is provided with a plug hole for the plug-in column 30151 to pass through. A plurality of plug-in columns 30151 can be arranged, and the vertical projection size of the plug-in column 30151 is smaller than the plug hole on the second ear plate 3014. The size of the hole is convenient for the plug-in column 30151 to pass through the socket. A side groove 30153 is provided at the upper end of the plug-in column 30151. A clamping block 30152 is provided inside the side groove 30153. The clamping block 30152 is a right-angled triangular wedge block. A spring 30154 is provided between the clamping block 30152 and the inner wall of the side groove 30153. The length of the spring 30154 is smaller than the size of the side groove 30153, which can prevent the clamping block 30152 from detaching from the side groove 30153 and facilitate the left and right movement of the clamping block 30152. When the plug-in column 30151 passes through the second ear plate 3014, the lower plane of the clamping block 30152 contacts the upper surface of the second ear plate 3014.

[0045] In this embodiment, preferably, the universal reinforcement component 302 includes a universal adjustment ball seat 3021 fixed on the surface of the second fixing ring 3011. The universal reinforcement component 302 is convenient for changing its installation angle and height, and is convenient for adapting to the distance between the steel bar and the corrugated pipe fitting 200. The universal adjustment ball seat 3021 has a self-locking mechanism, which is a common structure and can be purchased on the market. After the universal adjustment ball seat 3021 is locked, the structure is more stable. A screw 3022 is provided on the upper surface of the spherical block of the universal adjustment ball seat 3021, and a sleeve 3023 is sleeved on the screw 3022. A rotatable first clamp 3026 is provided on the front surface of the sleeve 3023. The structure of the first clamp 3026, the transverse clamp 501 and the longitudinal clamp 502 is the same as that of the annular mounting component 301, but the size is more adapted to the size of the steel bar.

[0046] In this embodiment, preferably, a mounting ring 3024 is sleeved on the sleeve 3023, and a limiting bolt 3025 is arranged between the two. The height adjustment of the mounting ring 3024 can further expand the height installation range of the first clamping member 3026. The height position of the mounting ring 3024 can be limited and fixed by the limiting bolt 3025. A universal ball seat member 3027 is arranged between the first clamping member 3026 and the mounting ring 3024 to facilitate changing the angle of the first clamping member 3026 and facilitate installation on the steel bar.

[0047] In summary, when fixing the prestressed construction corrugated pipe 200, the first fixing ring 3012 and the second fixing ring 3011 can be passed through the steel cage structure 100 to the outside of the corrugated pipe 200, and then the first fixing ring 3012 and the second fixing ring 3011 are docked, and the corrugated protrusions of the corrugated pipe 200 are embedded in the annular grooves 3016 on the inner sides of the first fixing ring 3012 and the second fixing ring 3011. Then, the sleeve 3023 can be rotated to change its height, thereby changing the height of the first clamping member 3026 on the sleeve 3023, so that the first clamping member 3026 is close to the steel bar. When the position is suitable, the first clamping member 3026 is sleeved and installed on the steel bar, and then the universal adjustment ball seat 3021 is locked to complete the fixation of the first fixing ring 3012 and the second fixing ring 3011. At the same time, the corrugated pipe 200 can be fixed, and the staff can adjust the length of the corrugated pipe 200 at equal intervals. Multiple positioning and installation structures 300 are installed at a distance to prevent the corrugated pipe fittings 200 from shifting during the concrete pouring process, thereby improving the installation stability of the corrugated pipe fittings 200 and further improving the work and construction efficiency. At the same time, when the first fixing ring 3012 and the second fixing ring 3011 are docked, the staff can align the plug-in column 30151 and pass it through the socket on the second ear plate 3014. When the plug-in column 30151 passes through the socket, the outer inclined surface of the block 30152 is squeezed to generate a horizontal component force, and the spring 30154 is compressed, and the block 30152 enters the side groove 30153. After the block 30152 passes through the socket, the spring 30154 rebounds, pushing the block 30152 to reset, and clamping the second ear plate 3014, the quick docking can be completed, eliminating the trouble of bolt connection of the traditional fixing ring, making it convenient for the staff to operate in a narrow space of the steel cage frame, thereby improving the convenience of use.

[0048] Embodiment 2

[0049] Reference Figure 5 and Figure 6 , which is the second embodiment of the present invention.

[0050] In this embodiment, preferably, the side positioning member 400 includes a semicircular supporting arc plate 401 sleeved on two longitudinal steel bars 101, a fixing plate 403 is vertically arranged on the outer surface of the semicircular supporting arc plate 401, and the two are connected by a connecting bolt 404 for easy assembly, a side positioning plate 402 for side positioning of the corrugated pipe fitting 200 is arranged between the two fixing plates 403, the side positioning plate 402 is U-shaped, the inner surface of the side positioning plate 402 contacts the outer surface of the corrugated pipe fitting 200, the fixing plate 403 is Y-shaped when viewed from the side, so that a gap is left at the lower end of the fixing plate 403 for the end of the side positioning plate 402 to extend into, a rectangular gap 405 is opened on the front and rear surfaces of the fixing plate 403, and a fixing column 406 passing through the rectangular gap 405 is arranged on the front and rear surfaces of the side positioning plate 402, a limiting ring 407 in contact with the surface of the fixing plate 403 is sleeved on the fixing column 406, and the limiting ring 407 has a diameter larger than the size of the rectangular gap 405.

[0051] In summary, when in use, the fixing plate 403 can be fixed to the outer surface of the semicircular support arc plate 401 by the connecting bolts 404 according to the distance between the upper and lower longitudinal steel bars 101, and the limiting ring 407 can be loosened at the same time to allow the fixing plate 403 to move outward along the fixing column 406 to change the distance between the two semicircular support arc plates 401. When the distance between the two is appropriate, the limiting ring 407 is tightened to make it contact with the surface of the fixing plate 403, and the friction resistance of the contact is used to achieve the fastening connection between the fixing plate 403 and the fixing column 406. When the corrugated pipe fitting 200 is installed, the entire side positioning member 400 can be moved from the outside toward The corrugated pipe fitting 200 is close, and the two semicircular supporting arc plates 401 are respectively sleeved on the two longitudinal steel bars 101 in the upper and lower directions. The inner surface of the side positioning plate 402 contacts the outer surface of the corrugated pipe fitting 200. The friction resistance between the semicircular supporting arc plates 401 and the longitudinal steel bars 101 makes it difficult for the two to separate. At the same time, the semicircular supporting arc plate 401 can be docked with another semicircular supporting arc plate 401, and connected through the plug-in component 3015 between the two semicircular supporting arc plates 401, forming a structure with the same structure as the annular mounting component 301 but different size, thereby realizing the stable installation and casting of the corrugated pipe fitting 200.

[0054] In the present embodiment, preferably, a connecting member 500 is provided between the cross-distributed longitudinal steel bars 101 and the transverse steel bars 102. The connecting member 500 can be used to realize the fastening installation of the longitudinal steel bars 101 and the transverse steel bars 102, which can increase the fastening of the steel bars to each other compared with wire bundling. The connecting member 500 includes a longitudinal clamp 501 and a transverse clamp 502 respectively mounted on the transverse steel bars 102 and the longitudinal steel bars 101. A fixing seat 503 is provided on the lower surface of the longitudinal clamp 501, and a ball head rod 504 is provided on the upper surface of the transverse clamp 502. The spherical end of the ball head rod 504 is rotatably located in the fixing seat 503. The ball head rod 504 is combined with the fixing seat 503 to form a structure identical to the universal adjustment ball seat 3021, which has a self-locking function.

[0055] In summary, when in use, first put the transverse clamp 502 on the longitudinal steel bar 101, then install the longitudinal steel bar 101 vertically above the transverse steel bar 102, and let the longitudinal clamp 501 be put on the transverse steel bar 102, the longitudinal steel bar 101 and the transverse steel bar 102 form a cross shape, and because the ball head rod 504 and the fixed seat 503 are combined to form the same structure as the universal adjustment ball seat 3021, therefore, after self-locking, the transverse clamp 502 and the longitudinal clamp 501 are locked, increasing the assembly stability of the longitudinal steel bar 101 and the transverse steel bar 102.
