[0014] Furthermore, an inclined rod structure is arranged on the inner side of the grid core mold for structural reinforcement, and a reinforcing structure is arranged in the middle part of the outer side thereof to enhance the bending strength of the grid core mold.

[0015] Based on the casting construction process of the prefabricated formwork system of the wave-breaking frame block, the frame block is divided into three areas for formwork construction and casting, namely the lower frame structure, the flange frame and the upper frame structure;

[0016] First, the construction of the lower frame box structure is carried out, and the construction steps include: 1. Several trolley grooves are set longitudinally on the ground directly below the lower frame box structure; a corresponding number of lower rib support structures are set transversely according to the position of the lower rib plate, and multiple lower panel support structures are set between the lower rib support structures, and the lower inclined rib positive support and the lower inclined rib cross support are adjusted to set up the lower rib formwork for pouring the two lower rib plates; the adjustable support rod is flipped to be flush with the lower telescopic truss, and the lower panel support structure is in an extended state, and the lower panel cross support is adjusted. The lower panel inner formwork is spliced ​​and built between the lower rib formworks, and the lower panel inner formwork is connected and supported by the lower panel support structure; the lower truss support and the lower telescopic truss support are adjusted so that the upper end surfaces of the lower rib support structure and the lower panel support structure are located in the same horizontal plane, so as to build the lower grid formwork group on their upper ends; 2. Splice and build the lower grid formwork group, and the lower grid formwork group is connected The horizontal inner support and the longitudinal inner support are supported separately, and a grid core mold is arranged in each cell structure. Telescopic support rods are respectively set between the horizontal inner support and the grid core mold and between the longitudinal inner support and the grid core mold; 3. The outer mold of the lower protective panel is built parallel to the inner mold of the lower panel, and the steel bars are arranged and the lower frame box structure is cast; 4. The lower frame box structure casting body is demolded. After the strength of the poured concrete reaches 85% of the design strength, the grid core mold, the horizontal inner support, the longitudinal inner support, the lower grid template group and the outer template are removed in turn. After the strength reaches 100% of the design strength, the bottom support structure is distributed and dismantled, the lower truss support and the lower telescopic truss support are adjusted, the vertical support force is unloaded, the adjustable support rod is flipped and stored directly below the lower telescopic truss, and the lower panel brackets on both sides are retracted to the lower rib plate. The trolley drag plate located in the trolley slot drags the bottom support structure longitudinally to withdraw from the lower frame box structure casting body;

[0017] Secondly, build the flange frame casting template outside the lower frame structure casting body and cast it. After the strength reaches 100% of the design strength, remove the formwork;

[0018] Finally, cast the upper frame box structure. First, set steel piers in the completed lower frame box structure, and support slides and slides thereon. Build a top support structure at the upper end of the lower frame box structure. The structural base is connected to the slide. A corresponding number of upper rib support structures are set transversely according to the position of the upper ribs. Multiple upper panel support structures are set between the upper rib support structures. Adjust the upper inclined rib support to set up the upper rib formwork for casting the two lower ribs.

[0019] Furthermore, the template joint seams on opposite sides of the cell structure are staggered.

[0020] Compared with the prior art, the prefabricated formwork system of the wave-breaking frame block and the pouring construction process thereof of the present invention have the following beneficial effects:

[0021] 1. The support of the guard plate and rib plate in the prefabricated formwork system adopts a trapezoidal structure and a panel support structure and a rib support structure arranged in parallel horizontally, which is easy to drag longitudinally as a whole to realize internal demoulding. The panel support structure can be laterally contracted to meet the needs of supporting and demolding, and has good formwork stability and support strength as a whole; the forming of the guard plate is divided into two parts, the upper panel support structure and the lower panel support structure are used as the construction base of the bottom frame formwork structure and the top frame formwork structure. Combined with the distributed casting method, the grid formwork group and the frame formwork structure can be easily disassembled, which is suitable for frame boxes with complex internal structures and large structural dimensions; the frame formwork structure adopts a combined core mold structure, which is easy to build a frame structure with complex structure and small structural thickness, with high construction efficiency, easy use, better versatility, easy disassembly and assembly, and high formwork strength;

[0022] 2. The frame blocks are cast in combination with the structure of the prefabricated formwork system. The frame blocks are cast in three steps to reduce the difficulty of casting frame blocks with complex internal frames and adapt to larger frame blocks. The first and third steps of casting are both trapezoidal structure castings, which is conducive to ensuring the stability of the formwork. The formwork is dismantled in steps according to the strength stage. The grid formwork group and the frame formwork structure are dismantled at 85% of the design strength. The bottom support structure and the top support structure are dismantled after 100% of the design strength. The prefabrication efficiency is improved while ensuring the molding quality. The hydraulic system is used for formwork adjustment and unloading and demolding. The support and dismantling of the prefabricated formwork system are highly mechanized, and the safety risk of construction operations is low. The prefabrication construction can be formed into an assembly line operation with the help of the trolley and slide technology, which greatly improves the efficiency of component prefabrication construction, reduces the cost of construction machinery and personnel, and has the conditions for large-scale and factory production.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only the best embodiments of the present invention, not all 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.

[0033] A prefabricated formwork system for wave-breaking frame blocks, used for casting and producing similar Figure 1 The frame block shown has a protective surface of an integrated structure, and the protective surfaces are connected to each other through the bottom frame 110 at the bottom and the top frame 230 at the top. In order to strengthen the support of the slope protective surface, ribs are arranged between the protective surfaces on both sides. Due to the complex internal structure and the large-sized thin-walled hollow grid structure of the block, it is necessary to reasonably design and arrange the prefabricated formwork system during molding to ensure the casting quality and consider the operability of supporting and removing the formwork;

[0034] Therefore, the frame box blocks are cast in steps, such as Figure 8As shown in the different shaded areas, the lower frame box structure 100 is cast, the flange frame box 140 is cast, and the upper frame box structure 200 is cast. The lower frame box structure 100 is cast to form the bottom sash 110, the lower guard plate 120 and the lower rib thin-wall structure of the frame box block. The flange frame box 140 is cast to form the flange frame box 140 structure outside the guard plate. The upper frame box structure 200 is cast to form the top sash 230, the upper guard plate 210 and the upper rib 220 thin-wall structure of the frame box block. Figure 2-Figure 7 As shown, the prefabricated formwork system based on the above-mentioned distributed casting frame block structure strategy includes a bottom support structure, a bottom frame formwork structure 500, a top support structure, a top frame formwork structure 800 and a casting formwork group, wherein the casting formwork group is constructed by splicing to form a casting path for each thin-walled structure of the frame block, and includes an outer formwork, a flange formwork, a lower grid formwork group, an upper grid formwork group, a lower rib formwork, an upper rib formwork, a lower panel inner formwork and an upper panel inner formwork, wherein the bottom frame formwork structure 500 is used to support the construction of the lower grid formwork group at the upper end of the bottom support structure to form a bottom grid 110 thin-wall casting path for the frame block, and the top frame formwork structure 800 is used to support the construction of the upper grid formwork group at the upper end of the top support structure to form a top grid 230 thin-wall casting path for the frame block;

[0035] Understandably, the casting formwork group is based on Figure 1 The frame box block structure is spliced ​​and built to form the pouring channels of each thin-walled structure, so the drawings do not show its template structures;

[0036] The bottom support structure is used to form the support of the lower panel inner formwork and the lower rib formwork, and includes a lower rib support structure 300 and a lower panel support structure 400 arranged in the transverse direction. Figure 2 and Figure 3 As shown, the lower rib support structure 300 and the lower panel support structure 400 are adapted to the frame box block structure, and both are trapezoidal structures. The lower rib support structure 300 is arranged according to the position of the lower rib 130, and several lower panel support structures 400 are arranged in parallel between the lower rib support structures 300;

[0037] Refer again Figure 2The lower rib support structure 300 includes a lower truss 310, a lower oblique rib bracket 320, a lower truss support 330, a lower oblique rib positive support 340 and a lower oblique rib cross support 350. The lower rib template is built on the outside of the lower oblique rib bracket 320. The lower oblique rib brackets 320 on both sides are connected and supported by the lower oblique rib cross support 350, and the support is further enhanced by the lower oblique rib positive support 340 perpendicular to the lower oblique rib bracket 320. The lower truss 310 and the lower oblique rib brackets 320 on both sides form a trapezoidal structure support to improve the support stability. The lower truss support 330 is located directly below the lower truss 310 and is used to vertically support the lower truss 310. In order to facilitate adjustment and ensure that the lower rib template obtains uniform support force everywhere, the lower truss support 330, the lower oblique rib positive support 340 and the lower oblique rib cross support 350 are all adjustable supports, using a screw rod structure or a hydraulic rod. The upper support is fine-tuned when supporting the mold, and the mold is returned and unloaded when the mold is removed for demoulding.

[0038] Refer again Figure 3 , wherein the dotted lines are the positions of the lower telescopic truss 410 and the lower panel support 420 in the formwork state, the lower panel inner template is connected to the outer end of the lower rib template, and the outer template is supported on the outer side of the lower panel inner template to form interconnected lower rib casting flow channels and lower guard panel 120 casting flow channels; due to the obstruction of the lower rib, the lower panel support structure 400 needs to be retracted to a width less than the distance between the two lower ribs 130 before the mold can be removed, which includes the lower telescopic truss 410, the lower panel support 420, the lower panel cross support 440, the lower telescopic truss support 450 and the adjustable module 430. Considering the support and height restrictions of the lower telescopic truss 410, the adjustable module 430 adopts rotation to adapt to the state; in the formwork state, the lower panel cross support 440 drives the lower panel supports 420 on both sides to move outward, and the adjustable support rod 431 is driven by the rotating hydraulic support 432 to rotate to a horizontal state, and is driven by the lower panel support 420 and the lower The gap between the telescopic trusses 410 rises until it is flush with the lower telescopic truss 410. The rotating hydraulic support 432 is a hydraulic support rod fixed with two end pins, which are respectively connected to the two ends of the adjustable support rod 431. The two end surfaces of the adjustable support rod 431 are wedge-shaped end surfaces, which cooperate with the lower telescopic truss 410 and the lower panel support 420 to achieve seamless splicing, so as to form a trapezoidal structure that can support the construction of the inner template of the lower panel on both sides; before demolding, the adjustable support rod 431 descends and rotates to be stored directly below the lower telescopic truss 410, and the lower panel cross support 440 drives the lower panel supports 420 on both sides to move inward and shrink until it is less than or equal to the size of the lower rib support structure 300. At the same time, the lower telescopic truss 410 descends to unload the supporting force. Similarly, the lower telescopic truss support 450 adopts a screw structure or a hydraulic rod for fine-tuning the upper force and unloading, and the lower panel cross support 440 preferably has hydraulic rods on both sides to facilitate large-stroke telescopic adjustment;

[0039] The lower truss support 330 and the lower telescopic truss support 450 are adjusted so that the lower truss 310 and the lower telescopic truss 410 are located at the same height position to jointly construct a construction plane of the bottom frame template structure 500. The bottom frame template structure 500 is supported on the construction plane for connecting and supporting the construction of the lower grid template group, such as Figure 4 As shown, in order to form a tic-tac-toe thin-walled frame structure, the lower grid formwork group is spliced ​​at the upper ends of the two lower protective surfaces to build a criss-cross frame casting path connecting the lower protective surfaces, and a lattice structure is constructed between the frame casting paths. The bottom frame formwork structure 500 includes a protective surface frame lattice support formwork 510 and an internal frame lattice support formwork 520. The protective surface frame lattice support formwork 510 is arranged in the protective surface lattice structure, and the internal frame lattice support formwork 520 is arranged in the internal frame lattice structure. The protective surface frame lattice support formwork 510 and the internal frame lattice support formwork 520 both include a horizontal inner support 511 and a vertical inner support 512. , a grid core mold 513 and a telescopic support rod 514, the grid core mold 513 is arranged in the middle of the lattice structure, which is fixed on the construction plane, the transverse inner support 511 is arranged in the transverse direction, and is used to support and fix the transverse grid template of the bottom frame template structure 500, and the longitudinal inner support 512 is arranged in the longitudinal direction, and is used to support the lower panel inner template extending to the casting area of ​​the lower frame box structure and the longitudinal grid template of the bottom frame template structure 500, and the grid core mold 513 is positioned and supported by the telescopic support rod 514 to connect the transverse inner support 511 and the longitudinal inner support 512, as shown in FIG. Figure 4 As shown, the number of telescopic support rods 514 is set as appropriate according to the length of the longitudinal grid template and the longitudinal inner support 512. The grid core mold 513 is a square frame, and its interior is structurally reinforced by diagonal rods. For longer mold rods, in order to enhance their bending strength, a reinforcement structure 513a is set on the outer side of the middle of the mold rod, as shown in FIG. Figure 4 In the example structure, the reinforcement structure 513a may be a U-shaped square folding rod;

[0040] For the omitted description and drawings, the outer formwork involved in the text adopts conventional combined steel formwork, and its structure and formwork method adopt conventional formwork methods in the prior art. In addition, since the flange frame casting area is located outside the main structure of the frame structure, there is no difficulty in casting and supporting the formwork of the main structure. Therefore, the flange formwork adopts the existing conventional formwork splicing and supporting method for formwork support;

[0041] After the lower frame box structure 100 is poured, the top support structure can be supported thereon, and the upper rib plate formwork and the lower panel inner formwork can be built. The top support structure includes an upper rib plate support structure 600 and an upper panel support structure 700 arranged in the transverse direction. Figure 5 and Figure 6As shown, the upper rib support structure 600 and the upper panel support structure 700 are adapted to the frame box block structure and are both trapezoidal structures. The upper rib support structure 600 is arranged according to the position of the upper rib 220, and several upper panel support structures 700 are arranged in parallel between the upper rib support structures 600.

[0042] Refer again Figure 5 The upper rib plate support structure 600 includes an upper truss 610, an upper oblique rib support 620, a structural base 630, an upper truss support 640 and an upper oblique rib support 650. The upper truss 610 and the upper oblique rib supports 620 on both sides form a trapezoidal structural support. Since the height dimension of the upper frame box structure 200 is relatively large, an integrated structural base 630 is required to be provided in the trapezoidal structural support for support. The structural base 630 is fixed on the lower frame box structure 100 and is located directly below the upper truss 610. The upper truss support 640 at the upper end vertically supports the upper truss 610, and the upper oblique rib supports 650 on both sides vertically support the upper oblique rib supports 620. The upper rib plate formwork is constructed on the upper oblique rib supports 620 on both sides. Similarly, the upper truss support 640 and the upper oblique rib support 650 are adjustable supports, and a screw rod structure or a hydraulic rod is used to fine-tune the upper support when supporting the mold, and return to the position to unload the mold when removing the mold for demoulding.

[0043] Refer again Figure 6, wherein the dotted line is the contracted state of the upper panel support structure 700. Since the height dimension of the upper frame box structure 200 is relatively large, the height space can be used for lateral contraction.

[0045] Based on the prefabricated formwork system of the wave-breaking frame block, the pouring construction process of the frame block is carried out in steps:

[0046] First, the lower frame box structure 100 is cast and constructed, and the construction steps include:

[0047] 1.

[0048] 2. Build a lower grid template group on the construction plane of the upper end surface of the lower rib support structure 300 and the lower panel support structure 400. The lower grid template group is spliced ​​to build a criss-cross thin-walled frame casting channel. When splicing the grid templates, it should be noted that the splicing seams on the opposite sides of the same cell structure should be staggered. The vertical and horizontal grid templates are supported by the horizontal inner support 511 and the longitudinal inner support 512 respectively. A grid core mold 513 is arranged in the middle of each cell structure. The grid core mold 513 is installed on the construction platform as a supporting base. Its four mold rods respectively press the horizontal inner support 511, the longitudinal inner support 512 and the lower panel inner template through the telescopic support rod 514 to provide support force. The support point of the telescopic support rod 514 should avoid the template splicing seam;

[0049] 3. Build the outer formwork of the lower guard plate 120 casting path parallel to the inner formwork of the lower panel, lay out the steel bars and cast the lower frame box structure 100 as a whole. When laying out the steel bars, the reinforcing connecting steel bars of the latter two castings should be reserved. In addition, the truncated cone nuts and the straight threaded steel bars are reserved on the side of the casting of the lower frame box structure 100 for the splicing connection between the frame box blocks;

Flip the adjustable support rod 431 and store it directly under the lower telescopic truss 410. Retract the lower panel brackets 420 on both sides to the inside of the lower rib plate. The trolley drag plate 360 ​​located in the trolley slot drags the bottom support structure longitudinally to withdraw from the casting body of the lower frame box structure 100.

[0051] Secondly, the flange frame 140 is cast and constructed. The flange frame 140 casting template is built outside the casting body of the lower frame structure 100. The reserved reinforced connecting steel bars should be buried in the casting flow channel of the flange frame 140 and cast. The formwork is removed after the strength reaches 100% of the design strength.

[0052] Finally, the upper frame box structure 200 is cast. The casting of the upper frame box structure 200 and the flange frame box 140 can be constructed simultaneously or successively. The casting construction process of the upper frame box structure 200 and the lower frame box structure 100 is substantially the same, as follows:

[0053] 1. A steel support pier is set in the casting body of the lower frame box structure 100 completed above, and a slideway is supported on the steel support pier, and a slide plate that can slide along the slideway is laid.

The upper panel inner template is supported by the upper panel support structure 700. The upper panel inner template is spliced ​​and built between the upper rib templates to build the upper rib 220 casting flow channel and the upper panel casting flow channel. The reserved reinforced connecting steel bars should be passed through the upper rib 220 casting flow channel and the upper guard panel 210 casting flow channel; adjust the upper truss support 640 so that the upper end surfaces of the upper rib support structure 600 and the upper panel support structure 700 are located on the same horizontal plane, so as to build the upper grid template group on the upper ends of the two;

[0054] 2. According to the construction process of step 2 and step 3 in the lower frame box structure 100, the outer formwork of the upper grid formwork group and the upper protective panel 210 is constructed and poured. Similarly, the side of the lower frame box structure 100 is reserved for the side of the cast body and the side of the reserved truncated cone nut and the straight thread section of the steel bar;

[0055] 3. Dismantle the cast body of the upper frame box structure 200. After the cast concrete strength reaches 85% of the design strength, dismantle the grid core mold 513, the horizontal inner support 511, the longitudinal inner support 512, the upper grid template group and the outer template in sequence. After the strength reaches 100% of the design strength, dismantle the top support structure in a distributed manner. Lower and adjust the upper truss support 640 to unload the vertical support force. The upper lifting truss support 730 drives the upper lifting truss 710 to descend. The upper panel brackets 720 on both sides shrink inward to within the upper rib 220. The trolley drags the slide plate in the longitudinal direction to drive the top support structure to withdraw from the cast body of the upper frame box structure 200.

[0056] 4. Remove the steel piers and slideways.

[0057] In order to more conveniently and efficiently uniformly adjust and locally fine-tune each support, the above adjustable supports and retractable supports all adopt hydraulic supports, and each hydraulic support has an independently controlled hydraulic branch and is connected to the hydraulic control system for overall control and sub-control operations.
