Description

Technical Field

[0001] This invention relates to the field of processing technology for insulated shear walls with bay windows, specifically a modular method for producing sandwich insulated shear walls with bay windows. Background Technology

[0002] Existing precast sandwich insulated shear wall components with bay windows, such as Figure 14 As shown, it includes a sandwich insulated wall and a bay window panel 500 (for shaping). The sandwich insulated wall includes an inner concrete wall 200 (for load-bearing), a sandwich ultra-thick insulation board 300 (for insulation), and an outer concrete wall 400 (for finishing). Currently, the bay window and the precast sandwich insulated shear wall are often produced separately. This not only involves complicated processing steps, but also results in poor connection stability and waterproofing between the bay window and the precast sandwich insulated shear wall. For example, a precast bay window mold (flat mold structure) disclosed in patent publication number CN220389788U includes a base, multiple side molds, and multiple outer molds. The inner side molds are installed on the base, and the multiple inner side molds can be detachably connected to form an inner mold. The outer molds are installed on the base, and the multiple outer molds can be detachably connected to form an outer mold. This bay window mold can only be used to manufacture a single bay window wall panel structure. Furthermore, since the height of wall panels with bay windows is generally fixed at the floor height, and the length of the sandwich insulated wall, the length of the bay window panel side panel, and the size of the bay window opening often vary, a set of molds needs to be made for each specification and size of wall panel. This results in problems such as complex processing procedures, low production efficiency, high production costs, and poor quality of prefabricated sandwich insulated shear walls with bay windows. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing methods and provide a modular method for producing sandwich insulated shear walls with bay windows. This method allows for the one-time casting of sandwich insulated shear walls with bay windows, resulting in good casting and forming effects, high-quality precast sandwich insulated shear walls with bay windows, high production efficiency, convenient operation, simple mold structure, and low production cost. Using this production method and mold, sandwich insulated shear walls with bay windows of various specifications and sizes can be produced, and adjustments are simple and quick, shortening construction time. Mold positioning and demolding are convenient and quick, avoiding component damage caused by forceful demolding. This effectively solves the problems in the background art.

[0004] To achieve the above object, the present invention provides the following technical solution: A production method for a modular sandwich insulated shear wall with a bay window, including a mold back plate, a mold front plate and two mold side plates provided on a fixed base, a side plate driving device for driving the mold side plates to move horizontally is provided on the fixed base, a front plate driving device for driving the mold front plate to move longitudinally is provided on the fixed base, and further including an inner mold for the bay window, an upper mold for the bay window and a lower mold for the bay window. The inner mold for the bay window includes an inner edge mold with a frame structure; the production method for the sandwich insulated shear wall with a bay window includes the following steps: Step S1: Fix the mold back plate on the fixed base, connect the mold side plates to the driving ends of the side plate driving device, and connect the mold front plate to the driving ends of the front plate driving device; Step S2: According to the size of the sandwich insulated shear wall, drive the mold side plates to move horizontally in place through the side plate driving device, and make the rear ends of the mold side plates abut against the front side surface of the mold back plate; Step S3: According to the size of the bay window opening, select an inner edge mold with a suitable size and fix it at the central position on the front side surface of the mold back plate; Fix the sandwich insulation board between the mold side plates, and leave a pouring gap for pouring the inner concrete wall between the sandwich insulation board and the mold back plate; Step S4: According to the size of the bay window wall panel, select an upper mold and a lower mold for the bay window with suitable sizes, fix the upper mold for the bay window at the top of the rear side surface of the mold front plate, and fix the lower mold for the bay window on the fixed base; Step S5: Drive the mold front plate to move through the front plate driving device to make it fit with the front end surface of the mold side plates. A pouring cavity is formed between the mold back plate, the mold side plates and the mold front plate. A pouring gap for pouring the outer concrete wall and the bay window wall panel is left between the front end of the sandwich insulation board and the mold front plate; Step S6: Pour concrete into the pouring gap above the pouring cavity. The concrete between the mold back plate, the mold side plates, the inner mold for the bay window and the back surface of the sandwich insulation board forms the inner concrete wall; The concrete between the front side of the mold side plates, the mold front plate, the inner mold for the bay window, the upper mold for the bay window and the lower mold for the bay window forms the bay window wall panel; The concrete between the front side of the sandwich insulation board, the bay window wall panel, the mold side plates and the inner mold for the bay window forms the outer concrete wall.

[0005] Further, the mold side plates are of a Z-shaped structure, and a pouring cavity with a "convex" shape can be formed between the mold back plate, the mold side plates and the mold front plate; and the transverse dimension of the front cavity of the pouring cavity is short, and the transverse dimension of the rear cavity of the pouring cavity is long; In step S3, the sandwich insulation board is fixed at the position of the rear cavity of the corresponding pouring cavity, and a pouring space for forming the bay window wall panel is formed between the inner mold for the bay window, the upper mold for the bay window, the lower mold for the bay window and the front cavity of the pouring cavity; The rear cavity of the pouring cavity is a pouring space for forming the sandwich insulated wall.

[0006] Furthermore, the mold side panel includes a flat sandwich insulation wall side template and an L-shaped bay window side template. The front end of the sandwich insulation wall side template and the rear end of the bay window side template abut against each other to form a Z-shaped mold side panel. The rear end of the sandwich insulation wall side template abuts against the mold back plate, and the front end of the bay window side template abuts against the mold front plate. The driving end of the side panel driving device is fixedly connected to the sandwich insulation wall side template. The inner end of the sandwich insulation wall side template is provided with an inner convex frame, and the longitudinal length of the inner convex frame is less than the longitudinal length of the sandwich insulation wall side template. The inner convex frame not only provides limiting support during the assembly of the sandwich insulation board, but also ensures that the width of the inner concrete wall is smaller than the width of the sandwich insulation board and the outer concrete wall, leaving installation space for the subsequent installation of the sandwich insulation shear wall. In step S2, the side plate driving device drives the sandwich insulation wall side template into position according to the size of the sandwich insulation shear wall. When the sandwich insulation wall side template moves laterally, the bay window side template moves with it. Furthermore, the fixing between the bay window side template and the sandwich insulation wall side template can be released according to the size of the bay window wall panel side plate. The size of the bay window wall panel side plate can be adjusted by moving the bay window side template laterally.

[0007] Furthermore, in step S2, the rear end of the sandwich insulation wall side template is fixed to the mold back plate by fastener one; the rear end of the bay window side template is fixed to the sandwich insulation wall side template by fastener two; the front end of the bay window side template is fixed to the mold front plate by fastener three; the bottom ends of both side plates of the bay window side template are fixedly connected to the fixed base; in step S4, the upper mold of the bay window is fixed to the top of the rear side of the mold front plate by fastener four.

[0009] Furthermore, the inner mold is an expandable and retractable rectangular frame structure, consisting of four L-shaped folding plates. The two flip plates of the L-shaped folding plates are movably connected by hinges. The inner mold of the bay window also includes a support member fixedly connected to the mold back plate. The upper, lower, left, and right side walls of the support member are each equipped with a telescopic cylinder, and the telescopic end of the telescopic cylinder is fixedly equipped with a U-shaped inner mold support leg. The inner mold support leg is movably connected to its corresponding two flip plates. The back of the two flip plates of the L-shaped folding plates are equipped with spikes for piercing and fixing the sandwich insulation board. In step S3, the telescopic cylinders on the support member open each L-shaped folding plate of the inner mold, and the inner mold unfolds to form a rectangular frame structure. When the inner mold unfolds, the spikes around it pierce into the edges of the reserved holes in the sandwich insulation board, thereby completing the positioning and clamping of the sandwich insulation board.

[0010] Furthermore, both ends of the inner mold support legs are provided with slot plates, and the inside of the slot plates is provided with a three-quarter arc slot; both ends of the two flip plates of the L-shaped folding plate are provided with snap-fit ​​plates, and the ends of the snap-fit ​​plates are provided with cylindrical protrusions that are adapted to the arc slots of the slot plates; the flip plates of the L-shaped folding plate are movably snapped into their corresponding slot plates through snap-fit ​​plates.

[0011] Furthermore, the upper mold of the bay window is a rectangular scoop-shaped structure with openings on the top and front sides. The upper mold of the bay window is composed of an upper mold and an upper replacement mold joined together. Both the upper mold and the upper replacement mold are semi-scoop structures, and the length of the upper mold is greater than the length of the upper replacement mold. The mating end face of the upper mold is provided with a tenon groove, and the mating end face of the upper replacement mold is provided with a tenon. The upper mold and the upper replacement mold are fixed together by a mortise and tenon structure formed between the tenon and the tenon groove. The upper mold of the bay window and the lower mold of the bay window have the same structure and are arranged symmetrically. In step S4, the length of the upper mold of the bay window can be changed by replacing the upper replacement mold of different lengths. Similarly, the length of the lower mold of the bay window can also be changed by replacing the lower replacement mold of the lower mold, that is, the size of the top and bottom panels of the bay window wall can be adjusted.

[0012] Furthermore, the side plate driving device includes a side plate fixedly mounted on a fixed base on the outside of the mold side plate, and a horizontally mounted telescopic cylinder II is fixedly mounted between the side plate and the mold side plate; the telescopic end of the telescopic cylinder II is fixedly connected to the side template of the sandwich insulation wall.

[0013] Furthermore, the front plate driving device includes driving boxes located at the bottom of both sides of the front end face of the mold front plate. A helical rack is provided longitudinally on the fixed base at the position corresponding to the driving box, and the driving box is slidably nested on the corresponding helical rack. A reduction motor is provided in each driving box, and a gear that meshes with the helical rack is provided on the shaft of the reduction motor. A support rod is provided on each driving box, and the top end of the support rod is fixedly connected to the upper end of the mold front plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) A "U"-shaped casting cavity is formed between the mold back plate, mold side plate and mold front plate. Before casting the sandwich insulation shear wall, the sandwich insulation board is placed in the casting cavity.

The back of the mold side plate, the inner mold of the bay window, the upper mold of the bay window and the lower mold of the bay window and the front of the sandwich insulation board form the casting space for forming the outer concrete wall. The back of the mold back plate, the mold side plate, the inner mold of the bay window and the back of the sandwich insulation board form the casting space for forming the inner concrete wall. Therefore, the sandwich insulation shear wall with bay window can be cast in one go. The sandwich insulation shear wall with bay window has a good casting effect, high production efficiency, convenient operation, simple mold structure and low production cost.

[0015] (2) The sandwich insulation board is initially clamped and limited by the side templates of the sandwich insulation wall on both sides. Then, the spikes of the inner side mold are inserted into the edges of the reserved holes of the sandwich insulation board to complete the positioning and clamping of the sandwich insulation board, thereby improving the casting accuracy of the sandwich insulation shear wall mold and the forming effect of the sandwich insulation shear wall.

[0016] (3) The lateral length of the sandwich insulation wall panel can be adjusted by driving the side plate of the mold to move laterally through the side plate driving device; the lateral dimensions of the top and bottom plates of the bay window wall panel can be adjusted by changing the upper and lower replacement molds; the lateral dimensions of the side plates of the bay window wall panel can be adjusted by moving the bay window side template laterally; the dimensions of the bay window opening can be adjusted by changing L-shaped folding plates of different sizes, so that the mold can adjust the dimensions of the bay window wall panel; using this production method and mold, sandwich insulation shear walls with bay windows of various specifications and sizes can be produced, and the adjustment operation is simple and quick, shortening the construction time and improving production efficiency.

[0017] (4) The side plate can be driven to move laterally by the side plate driving device to achieve quick positioning and demolding of the side plate; the inner mold can be expanded or contracted by the telescopic cylinder to achieve quick positioning and demolding of the inner mold of the bay window; the front plate can be driven to move longitudinally by the front plate driving device to achieve quick positioning and demolding of the front plate of the mold and the upper mold of the bay window; the positioning and demolding of the mold is convenient and quick, improving production efficiency and avoiding damage to components caused by violent demolding.
