DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0026] The embodiment provides a kind of inverted arch precast block steel bar installation mold frame, as shown in Figures 1 to 5As shown, the support frame is provided with detachable bent bar positioning rods and longitudinal bar positioning rods 1. The bent bar positioning rods are arranged at intervals along the extension direction of the preset arc line, which matches the bent arch of the inverted arch precast block. The longitudinal bar positioning rods 1 are arranged at intervals along the chord line of the preset arc. The longitudinal bar positioning rods 1 and the bent bar positioning rods are both provided with steel bar clamping grooves 4 arranged at intervals along the length direction. The steel bar clamping grooves 4 of the longitudinal bar positioning rods 1 and the bent bar positioning rods are both directed to the same direction, which facilitates the movement of the steel bar cage in the same direction after being formed, so that the longitudinal bars and the bent bars are simultaneously separated from the steel bar clamping grooves 4 of the longitudinal bar positioning rods 1 and the steel bar clamping grooves 4 of the bent bar positioning rods, avoiding affecting the disassembly of the bent bar positioning rods and the longitudinal bar positioning rods 1.

[0027] Working principle:

[0028] First, the bent bar positioning rods and the longitudinal bar positioning rods 1 are installed on the support frame. Then, the longitudinal bars of the inverted arch precast block are clamped into the steel bar clamping grooves 4 of the longitudinal bar positioning rods 1, and the bent bars of the inverted arch precast block are clamped into the steel bar clamping grooves 4 of the bent bar positioning rods. The steel bar clamping grooves 4 are specially designed for the positioning of the steel bars, which can ensure that the steel bars maintain the predetermined position and interval during the manufacturing of the steel bar cage. Then, the cross bars and the vertical bars are bound and welded on the longitudinal bars and the bent bars to form the steel bar cage. Finally, the steel bar cage is moved to separate the longitudinal bars and the bent bars from the steel bar clamping grooves 4, and then the bent bar positioning rods and the longitudinal bar positioning rods 1 are detached from the support frame, and the steel bar cage can be taken out from the support frame. By positioning the longitudinal bars and the bent bars through the inverted arch precast block steel bar installation mold frame, the longitudinal bars and the bent bars can have accurate position and interval in the steel bar cage, which ensures the continuity and integrity of the steel structure, thereby ensuring the structural integrity and construction quality of the precast block and providing a solid foundation for the subsequent pouring of the inverted arch precast block.

[0029] In an embodiment, as Figures 1 to 5As shown, the bent bar can be bent in the inverted arch prefabrication yard, and the bending angle and arc of the required steel bar are bent by professional machinery to meet the design specification requirements. The bent bar is placed in the steel bar clamping groove 4 of the bent bar positioning rod according to the design drawing requirements. The spacing of the steel bar clamping groove 4 on the bent bar positioning rod and the longitudinal bar positioning rod 1 has two setting methods: one is to preset the matching spacing according to the spacing of the longitudinal bar and the bent bar in the steel bar cage, that is, the bent bar spacing preset value is a, and the spacing of the steel bar clamping groove 4 on the bent bar positioning rod is a, and the spacing of the steel bar clamping groove 4 on the longitudinal bar positioning rod 1 is a; the other is to preset the standard value spacing of the bent bar positioning rod and the longitudinal bar positioning rod 1, and then divide the spacing value of the adjacent two steel bars by the standard value to obtain the multiple of the standard value, and then clamp the adjacent two steel bars into the two steel bar clamping grooves 4 with the spacing of the standard value, for example: the spacing value of the adjacent two longitudinal bars is b, the spacing of the steel bar clamping groove 4 is a, b=a, and the adjacent two longitudinal bars are clamped into two adjacent steel bar clamping grooves 4, if b=3a, the adjacent two longitudinal bars are clamped into two steel bar clamping grooves 4 separated by two steel bar clamping grooves 4, and the spacing between the first end and the tail end of the steel bar clamping groove 4 is two steel bar clamping grooves 4, so the spacing is 3a, that is, the spacing value b of the two longitudinal bars.

[0030] In an embodiment, as shown in Figures 1 to 5 The support frame is provided with a longitudinal bar insertion port and a bent bar insertion port. The longitudinal bar insertion port is used for inserting the longitudinal bar positioning rod 1, and the detachable connection relationship between the longitudinal bar positioning rod 1 and the support frame is realized by plugging. The bent bar insertion port is used for inserting the bent bar positioning rod, and the detachable connection relationship between the bent bar positioning rod and the support frame is realized by plugging.

[0031] In an embodiment, as shown in Figures 1 to 5 The longitudinal bar positioning rod 1 and the bent bar positioning rod are both rectangular rods, and in the presence of the steel bar clamping groove 4, the longitudinal bar positioning rod 1 and the bent bar positioning rod form a structure similar to a comb. The longitudinal bar insertion port and the bent bar insertion port are both rectangular insertion ports. Of course, the rectangular rod is only a preferred way, and other shapes such as round rods and quadrangular rods can also be selected according to needs, and the corresponding insertion ports are circular insertion ports and quadrilateral insertion ports.

[0032] In an embodiment, as shown in Figures 1 to 5 The top of the preset arc line is arranged downward, so that the longitudinal bar positioning rod 1 is located above and the bent bar positioning rod is located below. In use, the bent bar positioning rod can be installed first, the longitudinal bar positioning rod 1 can be installed after the bent bar positioning is completed, and then the longitudinal bar positioning can be completed. When the steel bar cage is disassembled, the longitudinal bar and the bent bar are first separated from the steel bar clamping groove 4, and then the longitudinal bar positioning rod 1 and the bent bar positioning rod are disassembled, so that the steel bar cage can be taken out. The steel bar cage can be taken out by hoisting.

[0033] In addition to the above setting mode, the arc top of the preset arc line can be set upward, that is, the bent bar positioning rod is located above, and the longitudinal bar positioning rod 1 is located below. When in use, the longitudinal bar positioning rod 1 can be installed first, the longitudinal bar positioning is completed, then the bent bar positioning rod is installed, and then the bent bar positioning is completed. When the reinforcement cage is disassembled, the longitudinal bar and the bent bar are first separated from the reinforcement clamping groove 4, then the longitudinal bar positioning rod 1 and the bent bar positioning rod are disassembled, and then the reinforcement cage can be taken out. When the reinforcement cage is taken out, the hoisting mode can be used.

[0034] Of course, in addition to the above two modes of preset arc line vertical setting, the preset arc line horizontal setting mode is also not excluded, that is, the longitudinal bar positioning rod 1 and the bent bar positioning rod are arranged along the horizontal direction left and right, instead of up and down.

[0035] In an embodiment, as shown in Figures 1 to 5 The bent bar positioning rod includes an upper bent bar positioning rod 2 and a lower bent bar positioning rod 3. The upper bent bar positioning rod 2 and the lower bent bar positioning rod 3 are distributed up and down, that is, the upper bent bar positioning rod 2 is located above the lower bent bar positioning rod 3. After the bent bar positioning is completed, two layers of bent bars can be formed. Of course, the specific number of bent bar layers is determined when the reinforcement cage of the inverted arch precast block is designed. Correspondingly, the number of bent bar positioning rods is determined, and it is not limited to two layers of upper and lower layers.

[0036] In an embodiment, as shown in Figures 1 to 5 The support frame includes a left support and a right support. The left support and the right support are connected through a connecting frame to form a complete support frame. The left support and the right support are correspondingly provided with a longitudinal bar insertion port and a bent bar insertion port, so that the longitudinal bar positioning rod 1 and the bent bar positioning rod can be simultaneously horizontally inserted into the left support and the right support to form a complete inverted arch precast block reinforcement installation mold frame.

The longitudinal bar insertion port and the bent bar insertion port corresponding to the upper bent bar positioning rod 2 are arranged on the mounting frame. The bent bar insertion port corresponding to the lower bent bar positioning rod 3 is arranged on the support leg.

[0038] In an embodiment, as shown in Figures 1 to 5As shown, the mounting frame includes a horizontal plate 5, an arc plate 6, and a vertical plate 7. The horizontal plate 5 is horizontally arranged, and both ends of the horizontal plate 5 are fixedly connected with both ends of the arc plate 6. The arc plate 6 is located below the horizontal plate 5, and the arc top of the arc plate 6 is arranged downward.

The arc plate 6 is fixedly connected with the connecting frame, and the bent bar insertion port corresponding to the upper bent bar positioning rod 2 is arranged on the arc plate 6. The longitudinal bar insertion port can be arranged on the horizontal plate 5, or on the vertical plate 7, or on both the horizontal plate 5 and the vertical plate 7.

[0039] In an embodiment, as shown in the drawings, Figures 1 to 5 As shown, the support leg includes an arc-shaped plate 8 and a corbel plate 9. The top end of the corbel plate 9 is connected with the arc-shaped plate 8, the bottom end of the corbel plate 9 is provided with a base plate 10 for horizontal placement, and the corbel plate 9 is connected with the connecting frame.

[0040] In an embodiment, as shown in the drawings, Figures 1 to 5 As shown, the connecting frame is a U-shaped piece 11.
