[0032] like Figure 1 As shown, a longitudinal beam mold with adjustable slope includes several bases 1, a bottom mold 2, flat side molds 4, curved side molds 6, and two end molds 5. The bottom mold 2 is mounted on top of the bases 1; the flat side molds 4 and curved side molds 6 are movably disposed on the front and rear sides of the bottom mold 2 and secured with bolts; the two end molds 5 are movably disposed on the left and right sides of the bottom mold 2 and secured with bolts; the bottom mold 2, flat side molds 4, curved side molds 6, and two end molds 5 form a mold cavity with an open top.

[0033] To improve the accuracy of mold closing and to counteract the expansion force generated during the concrete curing stage, several opening adjustment devices 8 are provided along the length of one side of the mold cavity opening.

[0034] To meet the requirements of different slopes or slope directions for the longitudinal beam column bearing platform and to facilitate quick assembly and disassembly, a slope adjustment plate 7 is provided at the location of the column bearing platform on the curved side mold 6 (on the side closest to the mold cavity). It is worth noting that the slope adjustment plate 7 is flat on the side closest to the curved side mold 6, and inclined along its length on the side closest to the mold cavity. When the casting is completed, the side of the column bearing platform closest to the mold cavity will form a slope.

[0035] like Figure 3 As shown, the bottom of the planar side mold 4 is provided with a number of bottom connectors 12 and a number of first claws (not marked in the figure) at equal intervals along its length direction; the left and right sides of the planar side mold 4 are provided with a number of first bolt holes at equal intervals along its height direction.

[0036] like Figure 8 As shown, at least two second claws 501 are spaced apart at the bottom of the end mold 5, and several second bolt holes are equally spaced on the left and right sides of the end mold 5 along its height direction.

[0037] like Figure 4 As shown, the bottom of the arc-shaped side mold 6 is provided with a plurality of bottom connectors 12 and a plurality of third claws 601 at intervals along its length direction; the left and right sides of the arc-shaped side mold 6 are provided with a plurality of third bolt holes at equal intervals along its height direction. The end mold 5 is bolted to the first bolt holes of the planar side mold 4 and the third bolt holes of the arc-shaped side mold 6 through the second bolt holes on its left and right sides, respectively.

[0038] Preferably, a slide block 11 is provided at the bottom of each of the first claws, second claws 501, and third claws 601; a limit groove 1101 is provided at both ends of each slide block 11; and at least two pulleys 1102 are provided along the length of the bottom of each slide block 11, such as... Figure 5 As shown.

[0039] like Figure 2 As shown, the bottom mold 2 is provided with slide rails 201 at the positions of several first claws 501, second claws 501, and third claws 601. The slide rails 201 are all fixed to the top of the base 1 at the corresponding positions by slide rail mounting seats 3. In order to prevent the slide seat 11 from disengaging from the slide rail 201, the shape of the limiting groove 1101 is adapted to the cross-sectional size of the slide rail 201, and a limiting baffle 2011 is provided at the end of the slide rail 201 away from the mold cavity. In use, the first claw of the planar side mold 4, the second claw 501 of the end mold 5, and the third claw 601 of the arc side mold 6 are all slidably connected to the slide rails 201 at the corresponding positions on the bottom mold 2 by pulleys 1102 on their respective bottom slide seats 11.

[0040] In order to improve the uniformity of the grouting material and ensure the uniform distribution of vibration force, several vibrator mounting seats 10 are evenly spaced along the length of the middle position of the outer side wall of the planar side mold 4 away from the mold cavity; vibrator mounting seats 10 are also provided at the middle position of the outer side wall of the central column bearing platform of the arc side mold 6.

[0041] like Figure 6-7 As shown, to address the issues of traditional longitudinal beam molds lacking positioning for pre-embedded bolts and the tendency for reinforcing bars to warp upwards during casting, the curved side mold 6 is provided with several first positioning holes 604 corresponding to the positions of the pre-embedded bolts; the curved side mold 6 is also provided with several reinforcing bar positioning holes 603 corresponding to the positions of the reinforcing bars. The slope adjustment plate 7 is provided with second positioning holes 702 corresponding to the positions of the first positioning holes 604; and the slope adjustment plate 7 is provided with reinforcing bar through holes 701 corresponding to the positions of the reinforcing bar positioning holes 603.

[0042] Preferably, the side of the arc-shaped side mold 6 with the column bearing platform away from the mold cavity is provided with rib positioning and clamping parts 602 in all four directions (up, down, left, right) around its vibrator mounting base 10, such as... Figure 10As shown, each reinforcing bar positioning clamping member 602 is provided with several pressing holes 6021 along its length. It is worth noting that the several pressing holes 6021 correspond one-to-one with the positions of several reinforcing bars in the components.

[0043] The bottom ends of the upper rib positioning clamping member 602 and the bottom of the left and right rib positioning clamping members 602 are provided with first connecting plates 6022; the reinforcing plates 605 of the arc-shaped side mold 6 are provided with second connecting plates 6051 at the positions corresponding to the first connecting plates 6022; the first connecting plates 6022 and the second connecting plates 6051 are bolted together.

[0044] During installation, several pre-embedded bolts pass through the second positioning hole 702 and the first positioning hole 604 in sequence and are then fixed to the outer side wall of the arc-shaped side mold 6 by the positioning device; one end of several component reinforcing bars is fixed to the inner side wall of the flat side mold 4, and the other end passes through the reinforcing bar through hole 701, the reinforcing bar positioning hole 603 and the pressing hole 6021 of the reinforcing bar positioning clamping part 602 in sequence.

[0045] It is worth emphasizing that the pressing holes 6021 of the upper and lower reinforcing bar positioning clamps 602 face downwards, while the pressing holes 6021 of the reinforcing bar positioning clamps 602 on the left and right sides are arranged opposite each other. In use, the upper and left and right reinforcing bar positioning clamps 602 are fixed to the reinforcing plate 605 by the first connecting plate 6022, and then the reinforcing bars of the component abut against each other with each pressing hole 6021. The lower reinforcing bar positioning clamps 602 are stuck between several reinforcing bars of the component at the corresponding positions of the reinforcing plate 605 above it and its pressing holes 6021, so as to prevent the reinforcing bars of the component from warping.

[0046] When the mold is closed, the limiting groove 1101 is fitted onto the surface of the slide rail 201, and the planar side mold 4, end mold 5 and arc side mold 6 are moved to a position close to the bottom mold 2. Then, the connection between the planar side mold 4, end mold 5 and arc side mold 6 is completed by fastening bolts. Then, several bottom connecting parts 12 at the bottom of the planar side mold 4 and arc side mold 6 are fixed to the front and rear outer side walls of the bottom mold 2 in sequence by fastening bolts. Finally, the opening adjustment device 8 is installed.

[0047] In addition, to accommodate longitudinal beam components of different lengths, when a short longitudinal beam is required, a smaller end mold can be installed on the side of the end mold near the mold cavity, and fixed by the short longitudinal beam end mold clamping member 9, thereby shortening the length of the longitudinal beam component.

[0048] During demolding, remove each opening adjustment device 8 and open all fastening bolts, then push the flat side mold 4, end mold 5 and arc side mold 6 away from the bottom mold one by one.

[0049] This utility model has a simple structure and reasonable design. Its front and rear side molds and end molds are all connected to the bottom mold by sliding connection, which facilitates mold closing / demolding, improves production efficiency and reduces the component damage rate caused by demolding. In order to meet the requirements of setting the slope of the longitudinal beam column bearing platform, a slope adjustment plate is added. In addition, this utility model effectively solves the problems of easy upward warping and lack of positioning of pre-embedded bolts when the reinforcing bars of traditional longitudinal beam mold components are poured by setting out reinforcement positioning clamping parts and positioning devices.
