[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0039] Embodiment one

[0040] As shown in Figure 1 A prefabricated building girder pouring formwork mounting structure, comprising:

[0041] The formwork 100, as shown in Figures 3-4 is generally integrally formed by plastic processing, comprising a formwork top surface 101, a circle of formwork side surfaces 102 extending downward around the periphery of the formwork top surface 101, and a cavity 103 formed inside the formwork top surface 101 and the surrounding formwork side surfaces 102. The cavity 103 can reduce weight, and is provided with transversely and longitudinally staggered reinforcing ribs. The lower edge of the formwork side surface 102 continues to extend outward horizontally to form a flange edge 104. The outer contour of the circle of flange edges 104 is rectangular, and the vertical end face of the free end of the outer edge of the flange edge 104 is a lapping surface 105 for abutting between the formworks 100. The lapping surface 105 is a vertical plane, which is used for lapping with the formwork 200 or lapping with the lapping surface 105 of the formwork 100 itself.

[0042] The formwork 200, as shown in Figures 5-6As shown, the template 200 and the formwork 100 are integrally formed by plastic processing, because plastic products can be recycled, if the formwork 100 or the template 200 is scrapped, it can also be recycled to be reprocessed into a new template 200 and formwork 100, the material will not be wasted, it is more green and environmentally friendly, the vertical projection of the template 200 is rectangular, the cross section of the template 200 is "convex" shape, including the left and right supporting surfaces 201 and the middle upwardly protruding forming surface 202, the supporting surface 201 and the bottom surface of the flange edge 104 of the formwork 100 abut, the forming surface 202 is used for the forming of the main beam; The bottom surface of the template 200 is provided with a reinforcing rib 204, which is mainly used to maintain the structural strength of the template 200 while reducing its own weight and saving materials, the first connecting hole 203 is provided on the end surface of the template 200, the number of the first connecting hole 203 is multiple, and they are uniformly distributed on the end surface, the positions of the first connecting holes 203 of adjacent templates 200 are consistent, and the two templates 200 can be connected by penetrating the first connecting holes 203 with fasteners, when connected, the end surfaces of the templates 200 are in close contact, the first connecting holes 203 are aligned, and multiple groups of fasteners penetrate the first connecting holes 203 from the inside of the reinforcing rib 204, thereby realizing the connection of the two templates 200. The height difference between the forming surface 202 and the supporting surface 201 and the thickness of the flange edge 104 of the formwork 100 are close to or equal to each other, so that the flange edge 104 is placed behind the supporting surface 201, and the upper surfaces of the flange edge 104 and the forming surface 202 are almost the same in height, and when they are equal, they can even realize smooth transition.

[0043] The support assembly 300, as shown, is used to support the bottom surface of the template 200 and the bottom surface of the formwork 100, and the present scheme has no additional requirements for the support assembly 300, and only needs to meet the support of the bottom surface of the template 200 and the formwork 100. Figures 1-2

[0044] The present scheme is applicable to the construction of the main beam, the template 200 is placed on the support assembly 300, adjacent templates 200 are connected by fasteners, one flange edge 104 of the formwork 100 is placed on the template 200, and the remaining flange edges 104 of the formwork 100 are supported by the support assembly 300, the width of the supporting surface 201 is ≥5cm, which is enough for the flange edge 104 to be placed, if the width of the supporting surface 201 is further expanded, if it can reach about 15cm, the formwork 100 has an expansion space of about 10cm, which can leave enough adjustment allowance during installation, and can improve the scene adaptability to meet the construction of the main beam of the dense rib floor with different spans. The formwork 100 and the template 200 are integrally formed by plastic processing, forming modularization, and are quickly connected by fasteners, which can be repeatedly used, reduce material waste, and save construction cost.

[0045] In actual installation, there are two cases: ​

[0046] The first type, such as Figure 2 As shown, the molding surface 202 and the supporting surface 201 are connected and transitioned through a vertical side end face. A gap exists between the side end face and the mating surface 105 of the mold shell 100. The mounting structure also includes a filler 400, which fills the gap. Adhesive tape 500 is also provided, applied above the gap formed by the filler 400, the mold shell 100, and the template 200. The filler can generally be made of wood or a wooden template. By filling the gap with the filler 400 and applying the adhesive tape 500, a smooth surface is achieved, improving flatness.

[0047] The second type, such as Figure 7 As shown, the molding surface 202 and the supporting surface 201 are connected and transitioned by a vertical side end face, which abuts against the mating surface 105 of the mold shell 100. Adhesive tape 500 is also provided, which is applied above the gap formed by the mold shell 100 and the template 200. By abutting against the mating surface 105 of the mold shell 100 with the side end face and applying adhesive tape 500, a smooth surface is achieved, improving flatness.

[0048] In practical applications, such as Figures 1-2 As shown, the support assembly 300 includes a scaffold body 301, a top support 302, and steel pipe support groups 303. At least two sets of steel pipe support groups 303 are located below the formwork 200, each set positioned below a different support surface 201. Each set of steel pipe support groups 303 includes multiple steel pipes arranged side-by-side. The steel pipe support groups 303 are limited by the top support 302, which is installed above the scaffold body 301. This solution uses a scaffold structure, with the steel pipe support groups 303 playing a primary supporting role in the support assembly 300. The U-shaped top support 302 provides limitation, and the three sets of steel pipe support groups 303 effectively support the underside of the formed surface 202 and the two support surfaces 201, ensuring stable installation. The use of readily available steel pipes from construction sites allows for rapid assembly.

[0049] In practical applications, such as Figures 5-6 As shown, a second connecting hole 106 is provided on the mating surface 105 of the mold shell 100. The second connecting hole 106 extends inward to the cavity 103 perpendicular to the mating surface 105. The second connecting holes 106 of adjacent mold shells 100 are in the same position and can be connected by fasteners passing through the second connecting holes 106. By connecting with fasteners, the mating surfaces 105 of adjacent mold shells 100 can be tightly connected without leaving gaps, and grout leakage will not occur during grouting.

[0050] Example 2

[0051] like Figure 8As shown, the difference from Embodiment 1 is that the bottom surface of the template 200 is provided with a limiting structure that forms a horizontal limit with the support 300. Specifically, the bottom surface of the template 200 is provided with a groove 205. The middle group of the three sets of steel pipe support groups 303, whose height is slightly higher than the two sides, extends into the groove 205. The width of the groove 205 is 17cm. The total width of the steel pipe support group 303, including the U-shaped top support 302, is 16-17cm, which just forms a horizontal limit. This prevents the template 200 from shifting left and right during installation, improving safety.

[0052] Example 3

[0053] like Figure 9 As shown, the difference from Embodiment 2 is that the groove 205 is provided with three grooves, forming three positioning points with the three sets of steel pipe support groups 303 and the top support 302, making the installation more secure.

[0054] Example 4

[0055] like Figure 10 As shown, the difference from Embodiment 2 is that the limiting structure is a lower protrusion 206, and the plurality of lower protrusions 206 abut against the two sides of a top support 302 in the middle to form a horizontal positioning.

[0056] Example 5

[0057] like Figure 11 As shown, the difference from Embodiment 1 is that the limiting structure is a groove 205, and the steel pipe support group is provided in two sets. The two sets of steel pipe support groups 303 are located below the two supporting surfaces 201 respectively, and are applied to the main beam with a smaller width.

[0058] In summary, the prefabricated building main beam casting formwork installation structure described in this utility model has the advantages of simple structure, convenient installation, reusability, and the ability to meet the construction requirements of ribbed floor slab main beams with different spans.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
