[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2 As shown, the formwork structure 1 of the window sill railing of one embodiment is arranged on the beam slab 2, and includes an inner formwork 10, an outer formwork 12, a connecting piece 14 and a flexible slurry-blocking strip 16, wherein the outer formwork 12 is arranged in parallel with the inner formwork 10, and the outer formwork 12 includes a first end 120 and a second end 122 arranged opposite to each other; the connecting piece 14 is arranged at the first end 120, and the outer formwork 12 is connected to the inner formwork 10 through the connecting piece 14; the flexible slurry-blocking strip 16 is close to the second end 122 and is arranged on the surface of the outer formwork 12 away from the inner formwork 10, wherein the flexible slurry-blocking strip 16 partially extends out of the second end 122.

[0028] The formwork structure 1 of the above-mentioned window sill and parapet connects the top of the inner formwork 10 and the outer formwork 12 through the connector 14, which effectively improves the stability of the outer formwork 12, reduces the risk of looseness caused by pouring and vibrating the outer formwork 12 and then leaking slurry and running out of the formwork, and sets a flexible slurry retaining belt 16 at the bottom and the flexible slurry retaining belt 16 extends out of the bottom of the outer formwork 12, ensuring the tightness between the bottom of the outer formwork 12 and the poured beam 2, preventing leakage from polluting the original structural surface, and effectively improving the overall visual quality. Therefore, the formwork structure 1 of the above-mentioned window sill and parapet avoids the occurrence of leakage, effectively ensures the pouring quality, and improves the overall visual quality.

[0029] Before pouring the window sill, first set the inner formwork 10 and the outer formwork 12 on the already poured beam slab 2. After the inner formwork 10 and the outer formwork 12 are fixed, pour concrete between the inner formwork 10 and the outer formwork 12. After solidification, remove the inner formwork 10 and the outer formwork 12 to form the window sill. Figure 1 As shown, the inner formwork 10 and the outer formwork 12 are arranged in parallel, and the window sill railing is formed between the inner formwork 10 and the outer formwork 12.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the surfaces of the inner template 10 and the outer template 12 away from each other are provided with an aluminum alloy frame 100, and the aluminum alloy frame 100 is fixed on the surface of the inner template 10 and the outer template 12. Wherein, the inner template 10 and the outer template 12 are both wooden templates. The aluminum alloy frame 100 is arranged on the surface of the inner template 10 and the outer template 12, which can not only improve the durability and overall rigidity of the wooden template, but also save steel, reduce weight, save cost, and effectively improve the casting quality of the window sill railing. Wherein, the shape of the aluminum alloy frame 100 can be either a mesh or a fence formed by multiple aluminum alloy bars. In addition, the fixing method of the aluminum alloy frame 100 to the inner template 10 and the outer template 12 can adopt a variety of methods, for example, the aluminum alloy frame 100 is nailed to the inner template 10 and the outer template 12 by screws, which is not limited here.

[0031] The outer formwork 12 includes a first end 120 and a second end 122 which are arranged opposite to each other. For the sake of convenience, the first end 120 is the top of the outer formwork 12, and the second end 122 is the bottom of the outer formwork 12. The top of the outer formwork 12 is connected to the top of the inner formwork 10 through a connector 14, which can improve the stability of the outer formwork 12, reduce the looseness caused by pouring and vibrating the outer formwork 12, and avoid the occurrence of slurry leakage.

[0032] like Figure 3As shown, in this embodiment, the connecting member 14 includes a first connecting rod 140, a second connecting rod 142, a crossbeam 144 and an angle brace 146. The crossbeam 144 is located between the first connecting rod 140 and the second connecting rod 142 and is connected to the first connecting rod 140 and the second connecting rod 142. The first connecting rod 140 is connected to the inner template 10, and the second connecting rod 142 is connected to the outer template 12. One end of the angle brace 146 is connected to the second connecting rod 142 and the crossbeam 144, and the other end is connected to the first connecting rod 140. The first connecting rod 140 can be connected to the inner template 10 by a fixing bolt. Furthermore, the fixing bolt passes through the first connecting rod 140, the aluminum alloy frame 100 and the inner template 10 in sequence, so as to fix the first connecting rod 140 and the inner template 10. Similarly, the second connecting rod 142 can also be connected to the outer template 12 by fixing bolts, and the fixing bolts pass through the second connecting rod 142, the aluminum alloy frame 100 and the outer template 12 in sequence, so as to fix the second connecting rod 142 to the outer template 12. Among them, the number of fixing bolts can be selected according to actual conditions and is not limited here. One end of the angle brace 146 is connected to the intersection of the second connecting rod 142 and the crossbeam 144, and the other end is connected to the first connecting rod 140. The crossbeam 144, the first connecting rod 140 and the angle brace 146 form a triangular structure, which improves the stability of the connecting member 14. In addition, the connecting member 14 can be a steel structure, and the first connecting rod 140, the second connecting rod 142 and the crossbeam 144 can be connected by welding.

[0033] A flexible slurry retaining strip 16 is provided at the bottom of the outer formwork 12 to reduce the occurrence of slurry leakage. Figure 2 and Figure 4 As shown, part of the flexible slurry retaining strip 16 extends out of the bottom of the outer formwork 12. By setting the flexible slurry retaining strip 16 higher than the formwork surface, the flexible extrusion during the pouring process ensures the density of the bottom of the formwork and the poured beam and slab 2, prevents leakage of slurry from polluting the original structural surface, reduces the labor input for subsequent cleaning, and effectively ensures the pouring quality, improving the overall visual quality.

[0034] In this embodiment, the flexible slurry-blocking belt 16 includes a convex guide rail 160 and a rubber strip 162. The convex guide rail 160 is arranged on the surface of the outer formwork 12 away from the inner formwork 10, and the rubber strip 162 is sleeved on the convex guide rail 160 and detachably connected to the convex guide rail 160. The surface of the outer formwork 12 away from the inner formwork 10 is the outer surface of the outer formwork 12, and the flexible slurry-blocking belt 16 is arranged on the outer surface of the outer formwork 12. The convex guide rail 160 is arranged on the outer surface of the outer formwork 12 and close to the second end 122 of the outer formwork 12, that is, the bottom of the outer formwork 12. The rubber strip 162 is sleeved on the convex guide rail 160. After the inner formwork 10 and the outer formwork 12 are set, the rubber strip 162 is pressed against the already cast beam slab 2. By contacting the surface of the lower beam slab 2 with the rubber strip 162, a better sealing effect can be achieved, thereby preventing leakage of slurry. In addition, the rubber strip 162 is detachably connected to the convex guide rail 160, which is convenient for installation and removal, and can be easily replaced when the rubber strip 162 is damaged or aged. Furthermore, in this embodiment, the thickness of the rubber strip 162 is greater than the thickness of the outer formwork 12, which can play a role in closing the gap between the outer formwork 12 and the beam plate 2.

[0035] In this embodiment, the convex guide rail 160 can be a steel bar, which is arranged along the length direction of the outer template 12 and is perpendicular to the outer template 12. Furthermore, in this embodiment, the steel bar is connected to the aluminum alloy frame 100 on the outer template 12 by bolts, that is, the steel bar is detachably connected to the outer template 12. Therefore, different flexible slurry retaining strips 16 can be used according to different working conditions, which expands the application range of the template structure 1 of the window sill railing. In other embodiments, the steel bar can also be connected to the aluminum alloy frame 100 by welding.

[0036] Please continue reading Figure 1 In this embodiment, the formwork structure 1 of the window sill railing also includes a diagonal brace 18, one end of the diagonal brace 18 is connected to the inner formwork 10, and the other end is connected to the beam slab 2. The diagonal brace 18, the inner formwork 10 and the beam slab 2 form a triangular structure, which improves the stability of the connection between the inner formwork 10 and the outer formwork 12. Among them, the connection between the diagonal brace 18 and the inner formwork 10 and the beam slab 2 is a detachable connection, for example, a bolt connection can be adopted. In addition, in this embodiment, the diagonal brace 18 is detachably connected to the aluminum alloy frame 10 on the inner formwork 10. In this embodiment, the inner formwork 10 and the outer formwork 12 are also connected by a water stop bolt 20.

[0037] The following is an explanation of the application and construction method of the above-mentioned window sill and parapet template structure 1. The application and construction method of the window sill and parapet template structure 1 of one embodiment includes the following steps:

[0038] Step 1: Install the inner formwork 10 on the poured beam slab 2. The window sill railing is formed on the beam slab 2. During construction, the inner formwork 10 is installed first. The installation method and manner of the inner formwork 10 can adopt conventional practices in the industry.

[0039] Step 2: Set the flexible grout-proofing tape 16 on the outer formwork 12, and make the flexible grout-proofing tape 16 partially extend out of the second end 122 of the outer formwork 12. The flexible grout-proofing tape 16 is set in advance, and the bottom of the flexible grout-proofing tape 16 is higher than the bottom of the outer formwork 12. Through flexible extrusion, the window sill railing is tightly connected to the poured beam slab 2 to avoid leakage.

[0040] Step 3: Connect the inner formwork 10 to the outer formwork 12 with the flexible mortar retaining tape 16 installed by means of the connector 14 to complete the construction of the formwork structure 1 of the window sill and parapet. Connect the inner formwork 10 and the top of the outer formwork 12 by means of the connector 14 to improve the stability of the outer formwork 12 and reduce the risk of formwork running during pouring and vibration.

[0041] The following uses a specific embodiment to illustrate the use process of the above-mentioned window sill railing template structure 1:

[0042] When in use, first make the inner formwork 10 and outer formwork 12 with aluminum alloy frame 100, then install the inner formwork 10 with a height of 600cm and a length of 1200cm, then install the diagonal brace 18, fix the height to 600cm and the angle to 60 degrees, then pass the water stop bolt 20 from the inside to the outside, and then install the outer formwork 12 with flexible slurry retaining strip 16, wherein the rubber strip 162 is 5cm higher than the bottom of the outer formwork 12. Adjust the deviation, install the connecting piece 14, connect the first connecting rod 140 with the inner formwork 10, and connect the second connecting rod 142 with the outer formwork 12, then adjust the inner formwork 10 and the outer formwork 12 to be straight, fix the water stop bolt 20 and diagonal brace 18, and then connect with the adjacent formwork in sequence. After the pouring is completed and the condition for demolding is met, first remove the outer formwork 12 and then the inner formwork 10 in the opposite order of installation, clean it up and turn it over to other working surfaces for use.

[0043] The formwork structure 1 of the above-mentioned window sill railing effectively improves the stability of the outer formwork 12 by arranging a connector 14 at the top, and reduces the phenomenon that the outer formwork 12 becomes loose due to pouring and vibrating the outer formwork 12, and then leaks and runs out of the formwork. The aluminum alloy frame 100 is effectively combined with the wooden formwork, which saves steel while improving the durability and overall rigidity of the wooden formwork, reduces weight, and is conducive to saving project costs. A detachable rubber strip 162 is arranged at the bottom to contact the beam slab 2 of the lower layer through flexible extrusion, thereby ensuring the compactness of the bottom of the outer formwork 12 and the beam slab 2, preventing leakage from contaminating the original structural surface, reducing the labor for subsequent cleaning, and improving the overall visual quality.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
