Description

Technical Field

[0001] The present invention relates to the technical field of precast components, and particularly relates to a pouring mold and a forming method for a flue board. Background Art

[0002] The flue board is an important ventilation facility in tunnel engineering, which is used to collect the smoke and harmful gases in the tunnel and discharge them to the outside through the flue, so as to improve the air quality in the tunnel and ensure the safety of vehicle traffic in the tunnel. Usually, in the hot summer weather, the tunnel flue board can also reduce the stuffy ambient temperature inside the tunnel to a suitable range through ventilation, ensuring the driving safety and comfort of passing vehicles.

[0003] At present, flue boards are usually constructed by precast components. Before precast pouring, first, according to the specific requirements of the tunnel project and the actual situation on site, the structural design and drawing work of the flue board are completed. Then, the steel bars are processed and welded according to the design requirements to make the skeleton structure of the flue board. Finally, the corresponding formwork is made according to the structural form of the flue board and the size of the steel bar skeleton. During precast pouring, the concrete raw materials are stirred in a certain proportion to ensure the uniformity and stability of the concrete, and the stirred concrete is poured into the formwork. The air is discharged through vibration and other means to make the concrete fully dense. After curing until the concrete gradually hardens and reaches the design strength, the formwork is removed to complete the precast of the flue board. When the corbel pouring at the top of the tunnel is completed during the tunnel project construction, the precast flue board is horizontally installed at the corbel to form a ventilation duct.

[0004] However, during the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the existing precast flue boards can only be precast one by one at a time, with low precast efficiency and a large demand for molds, resulting in high production costs. In addition, the existing technology usually adopts a flat pouring method during the precast component pouring, and it is necessary to rely on the pouring mold to form the six surfaces of the flue board respectively. However, due to the arc shape of the flue board, it is difficult to perform the feeding and vibrating operations during the pouring process.

[0005] The information disclosed in this background art section is only for enhancing the understanding of the background art of the present disclosure, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.

Detailed implementation manners

[0027] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0028] For the devices and the like involved in the following embodiments, if not otherwise specified, they are all conventional commercially available products.

[0029] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0030] To solve the technical problems of complex operation, low efficiency and high cost in the precast pouring of existing flue plates, this example discloses a pouring mold for flue plates. See Figure 1 , which includes a base 1, a fixed template 2, an intermediate template 3, an outer template 4, a transverse slide rail 5, a side template 6 and a top template.

[0031] Specifically, the base 1, as the support part of the flue plate pouring mold, needs to ensure the stable setting of the base 1, so as to ensure the safety and stability of the pouring mold during use. In this embodiment, see Figure 2 , considering that the working area ground may have problems such as unevenness, in order to avoid the adverse effects of the site environment factors on the layout and use of the pouring mold, this example sets a concrete leveling layer 11 at the ground to realize the relative anchoring between the flue plate pouring mold and the working area ground. Among them, the concrete leveling layer 11 includes several concrete leveling blocks. By adjusting the height of the concrete leveling blocks at the corresponding positions, the top surface of the concrete leveling layer 11 is in the same plane, thereby ensuring the reliable fixation between the pouring mold and the concrete leveling layer and avoiding the adverse effects of the uneven ground in the working area; at the same time, by setting a concrete leveling layer with a certain height, the reserved maintenance space can also be realized, ensuring the convenience and operability of later maintenance.

[0032] Considering that the existing precast pouring mold for flue plates can only realize the precast pouring of a single flue plate at a time, the precast efficiency is low, and when multiple flue plates are precast and poured at the same time, the corresponding number of pouring templates is required, resulting in higher production costs and larger production inputs; at the same time, due to the traditional flat pouring method used in the existing flue plate pouring, the site occupation area is large and the pouring is cumbersome, and finally the pouring quality cannot be effectively guaranteed. For this reason, in this embodiment, see Figure 1 , relative opening and closing templates are arranged on the base to realize the simultaneous vertical pouring of multiple flue plates. Thus, while saving the number of molds and the occupation of site space, the pouring material can be conveniently put in and vibrated through vertical pouring, greatly improving the operation convenience, reducing the production cost, and at the same time ensuring the reliable pouring quality of the flue plates.

[0033] Specifically, see Figure 1 , a fixed template 2 is relatively fixedly arranged on one side of the base 1. The fixed template 2 is perpendicular to the plane where the base is located and is used to form the corresponding surface of the flue plate. In order to realize the simultaneous vertical pouring of multiple flue plates, see Figure 1, several intermediate templates 3 are provided on the base 1 parallel to the fixed template 2, and an outer template 4 is arranged on the other side of the base 1. Thus, between the fixed template 2 and the intermediate template 3 close to the fixed template 2, between adjacent intermediate templates 3, and between the intermediate template 3 close to the outer template 4 and the outer template 4, casting spaces for corresponding thickness flue plates are formed by reserving cavities with corresponding widths, and the two side templates 6 are used to close the cavities except for the top. By pouring the casting material into each cavity, simultaneous casting of multiple flue plates can be achieved.

[0034] Among them, the relative distances between the fixed template 2, the intermediate templates 3, and the outer template 4 are set to be adjustable, so that mold opening can be conveniently realized and simultaneous casting of flue plates with multiple thicknesses can be achieved at the same time. For this purpose, refer to Figure 1 and 2 , several longitudinal slide rails 12 are arranged in parallel on the top surface of the base 1. Correspondingly, refer to Figure 2 , at the positions corresponding to the longitudinal slide rails 12 at the bottoms of each intermediate template 3 and the outer template 4, sliding members 13 matching the longitudinal slide rails 12 are respectively fixed. Thus, the relative movement of the intermediate templates 3 and the outer template 4 along the longitudinal slide rails is realized through the sliding members 13, so as to adjust the distance between the templates. Refer to Figure 3 , the sliding member 13 includes a sliding seat 131. The sliding seat 131 includes two seat plates arranged oppositely and symmetrically. A sliding wheel 132 for sliding contact with the longitudinal slide rail is arranged in the upper space between the two seat plates, and several pairs of symmetrically arranged anti-clamping wheels 133 are arranged between the two seat plates. Thus, the sliding member 13 is ensured to slide along the longitudinal slide rail 12 in a fitting manner, so as to avoid problems such as template misalignment and voids caused by non-fitting contact between the sliding seat and the slide rail between the templates, and further leakage of slurry during casting. In addition, to achieve simultaneous casting of multiple flue plates, the number of intermediate templates 3 is set to be at least one, so as to at least complete simultaneous vertical casting of two flue plates.

[0035] The side templates 6 are used to enclose the corresponding spaces between the fixed template 2, the intermediate templates 3, and the outer template 4 relatively from both sides to form a casting cavity. However, for the convenience of mold opening, the two side templates 6 need to move relatively closer to or farther away from the intermediate template. For this purpose, refer to Figure 1 , in this example, transverse slide rails 5 are respectively fixed on both sides of the base. Thus, through the movement of the side templates 6 along the rails, the opening and closing of the side templates 6 relative to the fixed template 2, the intermediate templates 3, and the outer template 4 are realized.

[0036] In this embodiment, since the opening and closing distance of the side formwork 6 is small, the side formwork 6 is moved along the corresponding transverse slide rail 5 by manual pushing. However, considering that the movement stability of the side formwork 6 during manual pushing is easily affected by the force application point and direction, which affects the smoothness during movement and ultimately affects the splicing accuracy of the side formwork 6. Therefore, in this embodiment, a number of side formwork sliders 51 matching the transverse slide rail 5 are provided at the bottom of the side formwork 6. Specifically, refer to Figure 4 and Figure 5 , in this example, an angular track 521 is provided at the top of the transverse slide rail 5. The side formwork slider 51 includes a seat body 511. A track wheel matching the angular track is provided between the two seat plates of the seat body 511 for rolling along the track; at the different ends on both sides of the seat body 511, guide groove blocks 512 are respectively provided, and guide grooves for matching and fitting with the two side wings 522 of the transverse slide rail 5 are provided at the guide groove blocks 512. Thus, through the engagement between the guide groove blocks 512 and the side wings of the transverse slide rail, the limit during the movement of the side formwork slider 51 is realized, enabling it to fit the transverse slide rail 5 and move along the track, thereby ensuring the smoothness of the opening and closing of the side formwork 6.

[0037] However, due to the large volume and heavy weight of the intermediate formwork 3 and the outer formwork 4, it is difficult to open and close them manually. To achieve the convenient movement of the intermediate formwork 3 and the outer formwork 4 along the longitudinal slide rail, in this embodiment, a hydraulic drive is set as the power source. Specifically, refer to Figure 1 , in this example, two hydraulic cylinders 7 are selected as the hydraulic drive, and a synchronous motor is used to ensure the synchronous expansion and contraction of the two hydraulic cylinders, ensuring the driving reliability. Specifically, in this example, the end of the hydraulic cylinder 7 on the side of the fixed formwork 2 is relatively fixed to the base 1, and the other end is relatively fixed to the outer formwork 4. Thus, the movement of the outer formwork 4 along the track is controlled by the expansion and contraction of the hydraulic cylinder 7. Among them, to achieve the reliable connection and transmission between the hydraulic cylinder 7 and the outer formwork 4, refer to Figure 1 , in this example, force transmission beams 8 for transmission connection with the two hydraulic cylinders 7 are respectively provided on the outer side of the outer formwork 4. The two sides of the force transmission beam 8 are respectively fixedly connected to the outer surface of the outer formwork 4 through rib plates, and in order to further ensure the stable force application of the outer formwork 4, in this example, a support rod is also hingedly provided between the outer formwork 4 and the force transmission beam 8 to provide corresponding support for the outer formwork 4.

[0038] The approach or separation of the outer formwork 4 relative to the fixed formwork 2 can be achieved through the hydraulic cylinder 7. To achieve the relative movement of each intermediate formwork 3 along the longitudinal slide rail, in this embodiment, a chain plate group is provided between the fixed formwork 2, each intermediate formwork 3 and the outer formwork 4. Through the transmission of the chain plate group, when the hydraulic cylinder 7 drives the outer formwork 4 to move correspondingly, each intermediate formwork 3 will follow. Specifically, in this example, the chain plate group is provided at the bottom positions of the fixed formwork 2, the intermediate formwork 3 and the outer formwork 4 to avoid affecting the later concrete pouring. Refer to Figure 2 , the chain plate group includes a number of chain plates 9 connected in sequence along the direction of the longitudinal slide rail. Refer toFigure 6 , the link plate 9 is specifically a strip-shaped plate body. A chute 91 with a certain length is axially provided on one side of the link plate 9, and a slider through hole 92 is provided at the end of the other side of the link plate 9. When the link plates are combined, see Figure 2 , sliders 93 are fixedly arranged at the bottoms of the intermediate template 3 and the outer template 4, and the sliders 93 pass through the slider through holes 92 of the corresponding link plates 9. At the same time, the sliders 93 also pass through the chutes 91 of the adjacent link plates. Thus, when the outer template 4 moves outward along the longitudinal slide rail under the push of the hydraulic cylinder, the slider 93 fixed to the bottom of the outer template 4 drives its corresponding link plate to move because it passes through the slider through hole 92 at one end of the link plate; the slider fixed to the bottom of the intermediate template adjacent to the outer template 4 is fixedly connected to its corresponding link plate and is slidably connected to and moves along the chute of the link plate at the bottom of the outer template 4. And at the initial moment, the slider corresponding to the intermediate template is located on the right side of the chute of the link plate corresponding to the outer template (see Figure 6 the direction shown). Thus, when the outer template starts to move under the drive of the hydraulic cylinder and the link plate at its bottom starts to move, due to the certain length of the chute 91, the adjacent intermediate template does not move. When the slider at the intermediate template moves to contact the left side of the chute of the link plate of the outer template, the intermediate template starts to move. Thus, the sequential opening or closing of the outer template and the intermediate template is realized through the transmission of the link plates.

[0039] Considering that there is a certain grouting pressure during the pouring of the flue duct plate, in order to prevent the distance between the fixed template 2, each intermediate template 3 and the outer template 4 from changing under the action of the grouting pressure, resulting in inconsistent thickness of the poured flue duct plate, in this embodiment, a positioning assembly 10 for positioning the relative distances between the fixed template, the intermediate template and the outer template during pouring is provided. Specifically, see Figure 1 and Figure 7, the positioning assembly located at the top of the casting mold includes a positioning seat 101 and a positioning rod 102. The positioning seat 101 is respectively arranged at the top positions of the fixed template 2, each intermediate template 3, and the outer template 4, and is correspondingly arranged along the direction of the matching positioning rod 102. A rod groove matching the diameter of the positioning rod 102 is provided at the top of the positioning seat 101 for embedding and placing the positioning rod 102 in the rod groove. After each template moves to the designed casting position under the driving and transmission of the hydraulic cylinder and the chain plate group, the positioning rod 102 is inserted into the corresponding positioning seats 101 that match it. In addition, in this example, to achieve the positioning function of the positioning rod 102, the positioning rod 102 is an external threaded rod, and a number of positioning nuts 103 are threadedly connected to its rod body. The number of positioning nuts 103 is twice the number of positioning seats 101. Thus, by adjusting the positions of the positioning nuts 103, the positioning nuts 103 are respectively clamped on both sides of each positioning seat 101 to achieve the limiting effect and prevent relative movement between the templates. Additionally, in this embodiment, in order to increase the contact area between the positioning nut 103 and the positioning seat, thereby improving the limiting effect and avoiding the adverse impact of vibration on the fastening of the positioning nut, gaskets are provided between each positioning nut and the positioning seat.

[0040] In this embodiment, each intermediate template 3 and the outer template 4 are respectively templates with an L-shaped cross-section. Their L-shaped structure can form the bottom of the flue gas duct plate during vertical casting, avoiding the need to additionally set a bottom template, thereby reducing the number of templates. During casting, in order to avoid problems such as slurry leakage at the combined part of the bottom of the template, in this embodiment, a positioning assembly 10 is correspondingly arranged at the bottom position of the template. Different from the positioning assembly at the top, considering the limited operating space at the bottom of the mold, in this example, positioning seats are only fixedly arranged at the bottoms of the fixed template 2 and the outer template 4. The positioning rod passes through between the two positioning seats and is fastened and limited by positioning nuts.

[0041] In order to achieve the stable connection and positioning of the side template 6 with the fixed template, intermediate template, and outer template after alignment, in this embodiment, refer to Figure 8 , a number of tie rod assemblies and alignment assemblies are respectively provided. Among them, the tie rod assembly includes a tie rod 62 correspondingly hinged to the end face position of the fixed template 2 or the outer template 4 through a hinge seat 61. A tie rod seat 63 matching the tie rod 62 is fixedly arranged at the corresponding end face position on the side of the side template 4. A tie rod groove for embedding the tie rod 62 is provided at the tie rod seat 63. In addition, in this example, the tie rod 62 is an external threaded rod, and a tie rod nut 64 is threadedly connected to its rod body. Thus, after the side template 6 is correspondingly attached to the fixed template, intermediate template, and outer template, the tie rod 62 is rotated to be correspondingly fitted into the tie rod seat 63, and then the tie rod nut 64 is tightened to limit the tie rod, thereby ensuring the relative stability of the position of the side template.

[0042] In addition, in order to further improve the stability of the side template during casting, refer to Figure 8, a number of alignment components are also provided at the side formwork. The alignment components include a plug 65 fixed to the side formwork and a slot 66 fixed to the fixed formwork, intermediate formwork or outer formwork for fitting the above plug. In this example, the alignment components include two forms. The first form can be seen in Figure 8 the alignment component shown in the upper position. It has an overall plate-like structure. The convex plug 65 is fixedly arranged at the side formwork, and the concave slot 66 is fixedly arranged at the intermediate formwork. Thus, through the cooperation and limitation of the plug and the slot, the relative stability between the side formwork and the intermediate formwork is achieved. Another form can be seen in Figure 8 the alignment component shown in the lower position. Its plug 65 is fixed to the side formwork through a seat body, and a through hole matching the plug is provided at the end face of the fixed formwork or outer formwork as the slot. Thus, through the alignment and cooperation of the protrusion at the seat body and this through hole, the alignment and limitation between the side formwork and the fixed formwork or outer formwork are achieved.

[0043] In order to avoid problems such as slurry leakage during pouring, in this example, sealing strips are respectively arranged at the corresponding contact end faces of the fixed formwork, intermediate formwork, outer formwork and side formwork to seal the gaps. In addition, for the convenience of operations such as grouting, see Figure 1 , workbenches are respectively provided at the outer top positions of the fixed formwork and the outer formwork, and ladders are respectively provided at the ends of the workbenches to facilitate the operators to climb to the workbenches and facilitate the vertical pouring operation.

[0044] In addition, in order to form the top surface of the flue gas duct plate during vertical pouring, in this example, the pouring mold further includes a number of top formworks. After each formwork is moved in place, the top formworks are hoisted and assembled to the top of the corresponding cavity of the mold through a number of lifting lugs arranged on the top surface of the top formworks, and then the tensioning positioning components are tightened to achieve the overall stability of the mold and ensure the smooth subsequent pouring.

[0045] This example also discloses a method for forming a flue gas duct plate, which is implemented based on the above-mentioned flue gas duct plate pouring mold, and specifically includes the following steps: (1) Correspondingly bind a steel reinforcement cage matching the flue gas duct plate to be poured, and embed lifting nails at the positions corresponding to the side and front of the flue gas duct plate on the steel reinforcement cage.

[0046] To ensure the structural strength of the flue gas duct plate after pouring and forming, a steel reinforcement cage needs to be placed in the pouring cavity as the internal reinforcement of the flue gas duct plate before pouring. In this embodiment, before pouring the flue gas duct plate, the steel reinforcement cage is bound in advance according to the design size and specifications of the flue gas duct plate. And in order to facilitate the removal of the flue gas duct plate from the pouring formwork after forming, in this example, lifting nails are embedded at the positions corresponding to the side and front of the flue gas duct plate on the steel reinforcement cage during the binding of the steel reinforcement cage, and the lifting nails are fixedly bound to the steel reinforcement cage body. Among them, since the lifting nails corresponding to the front of the flue gas duct plate are inside the flue gas duct plate during pouring and cannot leak out of the pouring surface of the flue gas duct plate, for subsequent hoisting use, the lifting nails corresponding to the front of the flue gas duct plate are embedded in the steel reinforcement cage with a rubber hose of a certain diameter to prevent the mortar from mixing with the lifting nails and affecting the hoisting.

[0047] (2) After controlling the hydraulic drive components to drive the outer formwork and the middle formwork to be close to the fixed formwork, push the side formworks on both sides to move along the transverse slide rails until they are in contact with the fixed formwork, the middle formwork and the outer formwork, place steel cages between the corresponding formworks, hoist the top formwork and adjust the positioning assembly and the tie rod assembly to fix the relative spacing and positioning between the formworks.

[0048] After the steel cage is tied, start the hydraulic cylinder to contract and drive the outer template to move toward the fixed template. Under the transmission of the chain plate group, as the outer template moves, each intermediate template approaches the fixed template in turn. After the L-shaped intermediate template and the bottom of the outer template are assembled in turn, the side templates on both sides are pushed by manpower to move along the horizontal slide rail until the side template fits with the fixed template, the intermediate template and the outer template, and the alignment components are correspondingly engaged. Then adjust each tie rod assembly to ensure that the side template fits firmly with the fixed template and the outer template. Then, hoist the pre-tied steel cage into each template cavity in turn. After the steel cage is hoisted, hoist each top template in turn, close each casting cavity, and then adjust each positioning component to complete the debugging and fixing of the casting mold.

[0049] (3) Pour concrete into the corresponding cavity between the templates at the top of the mold and vibrate it, and after the curing is completed, open the positioning assembly and the tie rod assembly to open the mold; When the mold is opened after maintenance, first open the positioning components, then lift the top mold in turn, loosen the pull rod components, pull the side molds on both sides away from the middle mold, complete the side mold opening, and then start the hydraulic cylinder to make the outer mold drive the middle molds to move in the direction away from the fixed mold in turn to achieve mold opening.

[0050] (4) Use a crane to lift the flue plate to the turning table based on the pre-buried hanging nails on the flue plate and turn it over.

[0051] After the mold is opened, the hook of the crane is connected to the pre-embedded hook on the top of the cast flue plate in turn, and the flue plate is lifted from the mold to the turning table by the crane. The upright flue plate is laid flat, and then the crane transports the flue plate to the storage area for storage through the hanging nails on the front of the flue plate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

Thus, if these modifications and variations to the present invention fall within the scope of the claims of this disclosure and their equivalent technologies, the present invention also intends to include these modifications and variations.
