In addition, the present application ingeniously sets a rib mold on the second mold body, which is particularly suitable for the production of a new type of ribbed thin-shell staircase (i.e., a staircase with reinforced ribs), which requires It should be emphasized that in the movable mold system of the ribbed thin-shell staircase of the present application, the rib mold can be independently controlled by the third telescopic drive device, so as to independently drive the rib mold to directly leave the reinforcing ribs of the prefabricated staircase without generating friction with the reinforcing ribs, thereby facilitating demoulding and not damaging the produced prefabricated stairs.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0040] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other component or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply 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 understood as a limitation on the present application.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0044] See also Figures 1 to 5 The embodiment of the present invention provides a ribbed thin-shell staircase movable mold system, including a support base 15 (which can be a specific structural form such as a base, a bottom platform, etc., or even directly the ground), a first mold, a second mold and a driving component arranged on the support base 15;

[0045] The first mold includes a first mold body 100;

[0046] The second mold includes a second mold body 200 and a rib mold 1. The rib mold 1 is detachably located at the end of the second mold body 200. The second mold body 200 faces the first mold body 100 (the surfaces facing each other are the mold working surfaces). The rib mold 1 is located at a side of the second mold body 200 away from the first mold body 100.

[0047] The driving assembly includes a first telescopic driving device 2, a second telescopic driving device 3 and a third telescopic driving device 4. The first telescopic driving device 2 is connected to the second mold body 200 to drive the second mold body 200 to approach or move away from the first mold body 100. The second telescopic driving device 3 is connected to the end of the second mold body 200 corresponding to the rib mold 1. Figure 5Specifically, a mounting seat 17 can be provided at the end of the second mold body 200 (which can be called the side mold) corresponding to the rib mold 1, and the second telescopic drive device 3 (which can be called the top mold device) is installed on the mounting seat 17 and then installed on the second mold body 200, so it is equivalent to installing the top mold device on the side mold, while the traditional top mold device is generally installed on the supporting foundation 15, which makes the ribbed thin shell staircase movable mold system have a smaller installation space and does not require a basic bracket, and has a simple structure; in addition, the demoulding efficiency is improved by utilizing the interaction between the side mold and the component. In addition, the telescopic portion of the second telescopic drive device 3 (such as the rod portion of the electric push rod) can move toward the first mold body 100 and pass through the second mold body 2 00, one end of the third telescopic drive device 4 is connected to the rib mold 1, and the other end is connected to the second mold body 200. Note: the connection referred to in this article includes direct connection and indirect connection. For example, it is mentioned below that the other end of the third telescopic drive device 4 is connected to the middle crossbeam 10. Since the middle crossbeam 10 is connected to the second mold body 200, this situation is understood as the other end of the third telescopic drive device 4 is indirectly connected to the second mold body 200. Obviously, through reasonable structural design, the solution that the other end of the third telescopic drive device 4 is directly connected to the second mold body 200 should also fall within the protection scope of the present invention. The third telescopic drive device 4 is used to drive the rib mold 1 to move toward the end or middle of the second mold body 200;

[0048] Among them, the first mold can be called a fixed mold, and the second mold can be called a movable mold, but this is not the only naming method. Since the first telescopic driving device 2 is connected to the second mold body 200 to drive the second mold body 200 to move closer to or away from the first mold body 100, it means that the ribbed thin-shell staircase movable mold system has at least one movable mold. If the first mold is also designed to be movable (non-fixed mold), such a replacement scheme will also fall within the protection scope of the present invention. In addition, since the ribbed thin-shell staircase movable mold system is designed with a rib mold 1, the ribbed thin-shell staircase movable mold system is particularly suitable for producing a new type of ribbed thin-shell staircase (i.e., a staircase with reinforcing ribs 5).

[0049] Combination Figure 6 and Figure 7 It is understood that the first mold (fixed mold) is the part that contacts the tread 7 of the prefabricated stair 6. Specifically, the fixed mold can be connected to the fixed support and the supporting base 15 by bolts, and its main working surface can be formed by bending steel plates to ensure a smooth transition of the stair surface. The second mold (movable mold) is the part that contacts the ribbed bottom surface 8 of the prefabricated stair 6. Its main working surface can be formed by bending steel plates to ensure a smooth transition of the stair surface. Of course, the fixed mold and the movable mold are not limited to steel plate materials.

[0050] In addition, the first telescopic drive device 2, the second telescopic drive device 3 and the third telescopic drive device 4 can be equipped with a control system, and the control system can be composed of (but not limited to) a PLC control module, so that the first telescopic drive device 2, the second telescopic drive device 3 and the third telescopic drive device 4 can be automatically controlled to realize demolding, mold closing and other actions, and can also support emergency stop, inching and other functions, wherein the demolding process should be divided into multiple motion steps according to the operation process, which will be described in detail below.

[0051] See also Figure 1 and Figure 2 According to one embodiment of the present invention, the first telescopic drive device 2 is an electric push rod or a hydraulic push rod, the second telescopic drive device 3 is an electric push rod or a hydraulic push rod, and the third telescopic drive device 4 is an electric push rod or a hydraulic push rod. Of course, in addition to using electric push rods or hydraulic push rods, any other suitable equipment, devices, and mechanisms that can realize telescopic drive will fall within the protection scope of the present invention. In addition, the number of the first telescopic drive device 2, the second telescopic drive device 3, and the third telescopic drive device 4 is not subject to special restrictions. Preferably, each is distributed in a suitable position of the mold in the form of multiple. For example, the first telescopic drive device 2 can be 3, which are respectively connected to the left and right ends and the middle of the second mold body 200, but the present invention is obviously not limited to this.

[0052] According to one embodiment of the present invention, the telescopic movement direction of the first telescopic drive device 2 and the telescopic movement direction of the second telescopic drive device 3 are both perpendicular to the second mold body 200, and the telescopic movement direction of the third telescopic drive device 4 is parallel to the second mold body 200. Since the rib mold 1 and the second mold body 200 are detachably arranged, the third telescopic drive device 4 can drive the rib mold 1 in a direction parallel to the second mold body 200 to directly leave the reinforcing rib 5 of the prefabricated staircase 6 without generating friction with the reinforcing rib 5, thereby facilitating demoulding. Of course, the telescopic movement direction of each telescopic drive device is not limited to this and can be flexibly adjusted as needed.

[0053] See also Figure 5According to one embodiment of the present invention, the rib molds 1 are arranged in pairs at the upper and lower ends of the second mold body 200, and the third telescopic driving device 4 is arranged in pairs at the upper and lower ends of the second mold body 200. More specifically, the second mold body 200 includes an inner plate 201 and two outer plate portions 202 connected to the upper and lower ends of the inner plate 201. The inner plate 201 is closer to the first mold body 100 than the outer plate 202, and the third telescopic driving device 4 is extended so that the two rib molds 1 are located at the ends (upper and lower ends) of the second mold body 200, the upper rib mold 1 is located between the inner plate 201 and the upper outer plate 202, and the lower rib mold 1 is located between the inner plate 201 and the lower outer plate 202. The rib mold 1 and the outer plate 202 enclose a casting and molding space for the reinforcing rib 5, and the space between the inner plate 201 and the first mold body 100 is a molding space for the main part of the cast prefabricated staircase 6.

[0054] See also Figure 1 According to one embodiment of the present invention, the ribbed thin-shell staircase movable mold system also includes a bracket 9 arranged on a supporting base 15, one end of a first telescopic drive device 2 is hinged to a second mold body 200, the other end of the first telescopic drive device 2 is hinged to the bracket 9, one end of a third telescopic drive device 4 is hinged to a rib mold 1, and the other end of the third telescopic drive device 4 is hinged to the second mold body 200. The hinged form allows the telescopic drive device to have more flexible activity space when driving the corresponding carrier.

[0055] See also Figure 2 and Figure 5 According to one embodiment of the present invention, the ribbed thin-shell staircase movable mold system also includes an intermediate crossbeam 10 arranged on the side of the second mold body 200 away from the first mold body 100, one end of the third telescopic drive device 4 is connected to the rib mold 1, and the other end of the third telescopic drive device 4 is connected to the intermediate crossbeam 10. The intermediate crossbeam 10 is provided to facilitate the installation of the third telescopic drive device 4.

[0056] See also Figure 3In addition, the ribbed thin-shell staircase movable mold system also includes a sliding guide support assembly arranged on the support base 15, the sliding guide support assembly includes a slide rail 11 arranged on the support base 15 and a sliding mechanism slidably installed on the slide rail 11, the sliding mechanism is connected to the second mold body 200, the extension direction of the slide rail 11 is consistent with the telescopic movement direction of the first telescopic drive device 2, specifically, the sliding mechanism includes two sliding limit plates 12 connected to the second mold body 200, the two sliding limit plates 12 can slidably buckle the slide rail 11 from both sides of the slide rail 11, the various components in the sliding guide support assembly are preferably made of a low friction coefficient, the sliding guide support assembly can limit the left and right lateral movement and up and down floating of the second mold body 200, so that the ribbed thin-shell staircase movable mold system is more stable and reliable during operation, of course, the sliding guide support assembly is not limited to the form of cooperation between the slide rail 11 and the sliding limit plate 12, and can also be implemented in the form of a slide groove, a sliding sleeve, etc., and various variations will fall within the protection scope of the present invention.

[0057] See also Figure 4 In addition, the ribbed thin-shell staircase movable mold system also includes a length adjustable mechanism, one end of the length adjustable mechanism is connected to the side of the first mold body 100 away from the second mold body 200, and the other end of the length adjustable mechanism is connected to the support base 15. As an embodiment, the length adjustable mechanism can adopt a structural form of a screw rod 13 plus a nut sleeve 14. The support length can be adjusted by screwing the nut sleeve 14 with a wrench, but the present invention is not limited to this form.

[0058] In addition, the present invention also provides a method for producing an assembled staircase, which adopts the above-mentioned ribbed thin-shell staircase movable mold system for production, and the assembled staircase production method comprises the steps of:

[0059] a. The first telescopic driving device 2 drives the second mold body 200 to approach the first mold body 100 to the mold closing state, so that the first mold body 100, the second mold body 200 and the rib mold 1 enclose a concrete pouring space, and the first mold body 100 and the second mold body 200 are fixed to each other, for example, bolts or similar connecting parts can be used to fix (tighten) the first mold body 100 and the second mold body 200. Of course, before this, initial preparations should usually be made: it should be ensured that the various mechanisms of the entire mold system can operate normally and the surfaces of the first mold body 100 and the second mold body 200 (including the mold working surface and other surfaces) should be checked. A certain degree of cleaning work is performed. Usually, during the initial preparation work, the first telescopic drive device 2 is in a retracted state, the second telescopic drive device 3 is in a retracted state, and the third telescopic drive device 4 is in an extended state. The second mold body 200 includes an inner plate portion 201 and an outer plate portion 202. The inner plate portion 201 is closer to the first mold body 100 than the outer plate portion 202. The third telescopic drive device 4 is extended so that the rib mold 1 is located at the end of the second mold body 200, specifically between the inner plate portion 201 and the outer plate portion 202, and is in contact with the outer plate portion 202 and the inner plate portion 201 respectively. The rib mold 1 and the outer plate portion 202 enclose a casting and molding space for the reinforcing rib 5;

[0060] b. Install the hole-opening tooling for forming the lifting holes 16 on the reinforcing ribs 5 and treads 7 of the prefabricated staircase 6. Specifically, the plastic sleeves for forming the lifting holes 16 and the bolts for fixing the sleeves can be installed. In order to facilitate lifting and installation, the ribs and treads 7 of the staircase are provided with lifting holes 16, so sleeves are required;

[0061] c. Applying a concrete release agent to the working surfaces of the first mold body 100, the second mold body 200 and the rib mold 1. Specifically, the concrete release agent can be applied by spraying, for example, by using a spray gun or a brush to evenly coat the concrete release agent on the surfaces of the first mold body 100, the second mold body 200 and the rib mold 1 for concrete molding;

[0062] d. pouring concrete material in the pouring space surrounded by the first mold body 100, the second mold body 200 and the rib mold 1 and vibrating it evenly, and then smoothing the upper surface of the poured concrete material after filling the pouring space. Specifically, the vibration operation can be performed by installing a vibration motor on the facades of the first mold body 100, the second mold body 200 and the rib mold 1, or by manually vibrating with a handheld vibrating rod;

[0063] e. Waiting for the poured concrete material to harden to the demoulding strength to form a prefabricated staircase 6 with reinforcing ribs 5. Of course, the reinforcing ribs 5 and the treads 7 of the prefabricated staircase 6 also have hanging holes 16 formed thereon. The specific range of demoulding strength can be that the strength of ordinary concrete usually reaches 10MPa~20MPa, and the strength of ultra-high performance concrete reaches 20MPa~30MPa. However, the specific range of demoulding strength is not used to limit the present invention. Once there are different requirements, the range of demoulding strength can be flexibly set;

[0064] f. Remove the hole-drilling tooling, and fix the formed prefabricated staircase 6 with the reinforcing ribs 5 to the second mold body 200 (specifically, the prefabricated staircase 6 can be fixed by bolts, but not limited to bolts), retract the first telescopic drive device 2, and demould the prefabricated staircase 6 from the first mold body 100. The first telescopic drive device 2 stops after retracting to a predetermined distance, and the first telescopic drive device 2 is locked;

[0065] g. Release the fixation of the prefabricated staircase 6 and the second mold body 200. Corresponding to the above, the bolts connecting the prefabricated staircase 6 and the second mold body 200 can be removed to retract the third telescopic driving device 4, so that the rib mold 1 is demoulded from the prefabricated staircase 6, specifically, the reinforcing rib 5 of the prefabricated staircase 6. Since the rib mold 1 and the second mold body 200 are detachably arranged, the rib mold 1 can be driven to directly leave the reinforcing rib 5 of the prefabricated staircase 6 without generating friction with the reinforcing rib 5, thereby facilitating demoulding;

[0066] h. Control the second telescopic driving device 3 to extend, pass through the second mold body 200 (specifically, pass through the through hole on the outer plate 202) to push the prefabricated staircase 6, so that the prefabricated staircase 6 is separated from the second mold body 200;

[0067] i. Install a hoisting device on the hoisting holes 16 formed on the reinforcing ribs 5 of the prefabricated staircase 6, and hoist the prefabricated staircase 6 away. Of course, the molds (including the first mold and the second mold) can be cleaned later, thus completing the entire staircase production process.

[0068] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
