[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0026] The core of the utility model is to provide a combined mold of prefabricated wall formwork, which can pour two walls at the same time, saves the turning over pouring step, has fewer construction procedures, low production cost and high production efficiency.
[0027] It should be noted that the thickness direction of the prefabricated wall formwork mentioned in the present application refers to the vertical direction of the other wall pointed by one wall; the length direction of the prefabricated wall formwork refers to the vertical direction of the thickness direction of the prefabricated wall formwork in the horizontal plane.
[0028] The combined mold of prefabricated wall formwork provided by the utility model comprises:
[0029] The outer formworks 1 are arranged in parallel, and the two outer formworks 1 are connected through the connecting pieces;
[0030] The core module units 3 comprise a plurality of elongated rods 31 and flexible cloths 32 fixedly wrapped outside the elongated rods 31, and the core module units 3 are arranged in parallel on the inner side of the outer formworks 1 and used as the inner formworks of the prefabricated wall formwork;
[0031] The elastic sealing pieces are used for filling the gaps between the adjacent two core module units 3, the gaps between the core module units 3 and the steel cage 01, and the gaps between the core module units 3 and the limiting pieces of the outer formworks 1.
[0032] Please refer to Figure 1 The core module units 3 are tightly fixed outside the elongated rods 31 by the flexible cloths 32, the size of the core module units 3 is mainly determined by the internal elongated rods 31 and the number and distribution, and the size of the core module units 3 is the sum of the outer contour size of the outermost elongated rod 31 and the thickness of the flexible cloths 32 on both sides.
[0033] The elongated rod 31 can be a cylindrical rod, a rectangular rod, a tapered rod, etc. The material of the elongated rod 31 is usually plastic or wood, which is light in weight and low in cost.
[0034] The flexible cloth 32 can be a geotextile, a silica cloth, or a composite cloth with at least two layers, so that the flexible cloth 32 has good waterproof performance and chemical stability, and the concrete poured into the core module unit 3 or even between the core module units 3 on both sides is avoided.
[0035] The flexible cloth 32 can be fixed to the outside of the elongated rod 31 by a steel wire rope, a fixed clamp, etc. The two ends of the flexible cloth 32 can be connected and wrapped around the elongated rod 31 by a magic tape, a mother buckle, etc. so as to fix the flexible cloth 32.
[0036] Considering the cost and assembly convenience, a steel wire rope is usually wrapped around the flexible cloth 32, which is used to fix the flexible cloth 32 to the outside of the elongated rod 31. On the one hand, the steel wire rope is easy to obtain and low in cost. On the other hand, the process of wrapping and unwrapping the steel wire rope is very simple and convenient to operate.
[0037] The type and model of the steel wire rope wrapped around the flexible cloth 32 are determined according to the actual production requirement of the tensioning force required for tightly surrounding the flexible cloth 32 around the elongated rod 31, so as to ensure that the core module unit 3 will not be scattered during the pouring process.
[0038] The number and distribution of the steel wire rope on the flexible cloth 32 are related to the height of the prefabricated wall formwork in actual production. For a lower prefabricated wall formwork, the steel wire rope can be arranged only at both ends of the core module unit 3 in the height direction to fix the flexible cloth 32. For a higher prefabricated wall formwork, the number of steel wire ropes can be increased in the middle of the core module unit 3 in the height direction.
[0039] In addition, it can be understood that, in order to facilitate the demolding of the prefabricated column cavity column, when the connecting member such as the steel wire rope used by the flexible cloth 32 will be in contact with the concrete, the outer surface of the connecting member is preferably provided with a demolding agent layer, so that the core module unit 3 can be smoothly separated from the concrete.
[0040] A plurality of core module units 3 are arranged along the length direction of the prefabricated wall formwork to form an inner formwork parallel to the outer formwork 1. Considering the steel reinforcement cage 01 of the prefabricated wall formwork itself, in order to avoid the core module unit 3 needing to pass through the steel reinforcement cage 01, the shape of the core module unit 3 is usually determined by the transverse steel bars of the steel reinforcement cage 01.
[0041] For example, please refer to Figure 1The sectional area of the core module unit 3 is rectangular, and the long side of the core module unit 3 abuts against the transverse steel bars of the steel reinforcement cage 01 arranged along the length direction of the prefabricated wall formwork, and the short side of the core module unit 3 abuts against the transverse steel bars of the steel reinforcement cage 01 arranged along the thickness direction of the prefabricated wall formwork.
[0042] According to actual pouring requirements, the length of the inner side formwork is usually less than the length of the outer side formwork 1, and the length of both is greater than the design length of the prefabricated wall formwork, so the inner side of the outer side formwork 1 is provided with a limiting piece for positioning the inner side formwork, so as to avoid displacement of the core module unit 3 of the assembled inner side formwork relative to the outer side formwork 1 during pouring, thereby affecting the size of the poured prefabricated wall formwork.
[0043] The limiting piece can be a limiting plate, a limiting rod, etc., and the connection mode of the limiting piece with the outer side formwork 1 is related to the material of the outer side formwork 1.
[0044] For example, when the outer side formwork 1 is a wooden formwork or a plastic formwork, the limiting piece can be connected to the inner side of the outer side formwork 1 by adhesion; and when the outer side formwork 1 is a steel formwork, the limiting piece can be fixed to the inner side of the outer side formwork 1 by welding or magnetic attraction.
[0045] Considering the gap between the core module unit 3 and the steel reinforcement cage 01, especially the gap in the thickness direction of the prefabricated wall formwork, and the gap between the core module unit 3 and the limiting piece of the outer side formwork 1, the concrete can enter the inner cavity of the prefabricated wall formwork, in order to block the concrete, the above-mentioned gaps are filled with elastic sealing pieces.
[0046] It should be noted that the elastic sealing piece between the core module unit 3 and the limiting piece also has the function of preventing the concrete from flowing out from both ends of the length direction of the combined mold, as shown in Figure 1 The outer side formwork 1, the core module unit 3, and the elastic sealing piece between the core module unit 3 and the limiting piece together enclose the area A of the concrete to be poured in the combined mold.
[0047] The elastic sealing piece can be an elastic pad such as a rubber sealing pad, which seals the above-mentioned gap by utilizing the elasticity of the elastic pad itself; or it can be an inflatable sealing pad, which is inflated to expand and tightly adhere to the core module unit 3, the steel reinforcement cage 01 or the limiting piece, thereby sealing the above-mentioned gap.
[0048] Considering the convenience of assembly, the elastic sealing piece is preferably an inflatable rubber tire 4, at least one end of the inflatable rubber tire 4 in the height direction is provided with an inflation port.
[0049] When the combined mold is assembled, first, the layout of the outer formwork 1 and the steel reinforcement cage 01 is completed, then according to the distribution of the steel reinforcement cage 01, each core module unit 3 is placed on the inner side of the outer formwork 1 according to the design size to enclose the inner formwork, and finally the inflatable rubber tire 4 is arranged between the core module unit 3 and the steel reinforcement cage 01 and between the core module unit 3 and the limiting piece, and after being placed in place, the inflatable rubber tire 4 is inflated to expand, so that the inflatable rubber tire 4 is tightly arranged with the core module unit 3, the steel reinforcement cage 01 and the limiting piece.
[0050] In addition, when the prefabricated wall formwork is high, the steel reinforcement cage 01 has multiple layers of transverse steel bars in the height direction, in order to avoid the transverse steel bars, the upper and lower transverse steel bars are usually arranged with different core module units 3, so that there is a gap between the two adjacent core module units 3, and the gap between the two adjacent core module units 3 needs to be filled and sealed by the elastic sealing member such as the inflatable rubber tire 4.
[0051] In the embodiment, the core module unit 3 is formed by wrapping the flexible cloth 32 with the slender rod 31, and the inner formwork of the prefabricated wall formwork is enclosed by the core module unit 3, which can simultaneously pour two wall bodies with the cooperation of the outer formwork 1 on both sides, thereby saving the traditional production process of turning over and pouring, saving a large amount of time and labor cost, reducing the occupation of the mold table during the production of the formwork, and significantly improving the production efficiency of the prefabricated wall formwork. At the same time, the core module unit can be reused, which reduces the cost of the mold.
[0052] On the basis of the above embodiment, the slender rods 31 in the core module unit 3 can be cylindrical rods, which are arranged in the length direction and the thickness direction of the prefabricated wall formwork, so that the shape of the core module unit 3 is relatively regular, and the outer side of the core module unit 3 is parallel to the outer formwork 1.
[0053] Please refer to Figure 1 The core module units 3 located at both ends of the length direction of the prefabricated wall formwork have relatively short lengths, and the sizes of the slender rods 31 in the same core module unit 3 can be the same to reduce the number of parts and the cost.
[0054] The core module unit 3 located in the middle of the length direction of the prefabricated wall formwork abuts against the steel reinforcement cage 01 through the elastic sealing member, and the same core module unit 3 is provided with a first slender rod and a second slender rod, the second slender rod is arranged at the end of the length direction of the core module unit 3, and the diameter d1 of the first slender rod and the diameter d2 of the second slender rod satisfy d1=nd2, n is a positive integer greater than or equal to 2, so as to increase the contact area of the core module unit 3 and the elastic sealing member, and better guarantee the sealing effect of the elastic sealing member.
[0055] On the basis of the above-mentioned embodiments, in order to conveniently pull and position the outer formworks 1, the outer formworks 1 are usually provided with steel formworks, and the steel formworks are provided with screw rod mounting holes for mounting the pull positioning screw rods 2 at both ends in the length direction, and the screw rod mounting holes are uniformly arranged along the height direction of the steel formworks.
[0056] Compared with the pull steel plate, the pull positioning screw rod 2 is more convenient to install and has lower cost; the type, model, number and spacing of the pull positioning screw rod 2 are determined according to the actual production needs to ensure that the outer formworks 1 on both sides do not relatively displace during pouring.
[0057] When the outer formwork 1 is a steel formwork or other metal formwork, the limiting piece can be provided as a magnetic base 11, which is adsorbed on the inner side of the outer formwork 1. On the one hand, the connection is reliable and stable, and on the other hand, the magnetic base 11 is convenient to disassemble and can be repeatedly used with different outer formworks 1 or with the same outer formwork 1 to pour prefabricated wall body molds of different lengths.
[0058] Of course, the limiting piece can also be provided as a limiting plate, which is vertically welded on the inner side of the outer formwork 1. Compared with the magnetic base 11, the connection with the outer formwork 1 is more stable and reliable, but it cannot meet the pouring needs of prefabricated wall body molds of different lengths and has relatively poor applicability.
[0059] It should be noted that the first and second in the first elongated rod and the second elongated rod in the present application are only used to distinguish the different positions, and do not limit the order.
[0060] The embodiments in the present specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the embodiments can be referred to each other.
[0061] The combination mold of the prefabricated wall body mold provided by the present application is described in detail. The principle and implementation manner of the present application are described by applying specific examples. The description of the above embodiments is only used to help understand the method and core idea of the present application. It should be pointed out that, for ordinary skilled persons in the technical field, without departing from the principle of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
