Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

When an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.

[0053] In the process of concrete construction, aluminum alloy formwork, plastic formwork and other building formworks are usually used for pouring concrete structures. However, it is difficult to construct the reentrant corner parts between the wall surfaces, between the wall and the floor, and other places due to the narrow space.

[0054] In the related art, cast-in-place concrete structure walls are usually constructed using aluminum alloy formwork or plastic formwork, and at the reentrant corner parts between the walls and the walls or the walls and the floor, connecting pieces similar to C-slots and mounting pieces such as pins are used to assemble the adjacent two formworks. However, such a connection method is time-consuming and labor-intensive, resulting in low construction efficiency.

[0055] To solve the problem of low construction efficiency at the internal corner in the related art, in a first aspect, with reference to Figure 1 An embodiment of the present application provides a kind of internal corner connecting template, including template main body and at least one L type connecting piece 400, wherein, template main body includes panel 100, also include vertical connection on panel 100 side plate 200 and / or connecting plate 300, L type connecting piece 400 is vertically arranged on panel 100, and with template main body form integrated arrangement, side plate 200 and / or connecting plate 300 and L type connecting piece 400 are all provided with several pin holes 610.

[0056] Wherein, connecting plate 300 is the component that is connected with wall template or floor template, side plate 200 is the component that is connected with adjacent other template main body.Pin hole 610 can be equidistantly arranged, while reducing the weight of side plate 200 and / or connecting plate 300 and L type connecting piece 400, it can also be realized by the cooperation of pin, fast installation.In addition, the internal corner connecting template in the embodiment can be applied to various construction scenes, including but not limited to the internal corner of wall-wall surface connecting place, the internal corner of wall-floor surface connecting place, the internal corner of wall-wall-floor surface connecting place, the internal corner of wall-beam connecting place, window hole internal corner and the internal corner of keel floor connecting place, etc., then the corresponding internal corner connecting template is wall-wall surface internal corner connecting template, wall-floor surface internal corner connecting template, wall-wall-floor surface internal corner connecting template, wall-beam internal corner connecting template, window hole internal corner connecting template, keel floor internal corner connecting template.For example, at the corner of wall template and wall template, i.e. the internal corner, wall-floor surface internal corner connecting template can be used for connection, and wall-wall-floor surface internal corner connecting template can be used for connection between the connecting angle of wall template and wall template and floor template.

[0057] Specifically, when the internal corner is constructed, the L type connecting piece 400 on the internal corner connecting template can be first placed on the internal corner, and then the L type connecting piece 400 on the internal corner connecting template and the adjacent building template (wall template or floor template) can be spliced and fixed through the cooperation of pin or other installation piece and pin hole 610, and the side of the internal corner connecting template adjacent to or away from the L type connecting piece 400 can be spliced and fixed with another adjacent building template (wall template or floor template), so as to realize the rapid construction at the internal corner.The template in the present application, such as internal corner connecting template, wall template, floor template, etc., can be aluminum alloy template, which has the advantages of light weight, stable connection, easy processing and recycling, etc.

[0058] For example, the internal corner connecting template is applied to the internal corner of wall-wall surface connecting place, at this time, the internal corner connecting template is also a kind of wall-wall surface internal corner connecting template, the L type connecting piece 400 is connected with adjacent wall template through pin, and the connecting plate 300 is connected with another adjacent wall template through pin.

[0059] In the embodiment, the L-shaped connecting piece 400 provided integrally with the template body is used to replace the C-shaped groove and its mounting piece in the related art, so that the convenience of workers in assembling two adjacent building templates at the internal corner can be improved, and thus the construction efficiency is improved. In addition, the flatness of the concrete cast at the internal corner can be ensured, so that the workers do not need to modify the concrete at the internal corner, and thus the construction efficiency and the concrete casting quality are improved.

[0060] With reference to Figure 1 In some embodiments, when the extrusion direction of any one target component of the L-shaped connecting piece 400, the side plate 200 and / or the connecting plate 300 is consistent with the extrusion direction of the panel 100, the target component and the panel 100 are integrally formed by the extrusion process.

[0061] Specifically, according to the above content, it can be known that the templates in the present application can be aluminum alloy profiles, so as to realize rapid production by the extrusion molding process. The panel 100 in the template has a relatively large surface area, so when the extrusion direction of any one target component of the L-shaped connecting piece 400, the side plate 200 and / or the connecting plate 300 is consistent with the extrusion direction of the panel 100, the target component and the panel 100 can be extruded together. For example, in the long-side internal corner connecting template described above, the L-shaped connecting piece 400 and the connecting plate 300 are target components whose extrusion direction is consistent with the extrusion direction of the panel 100, so the panel 100, the L-shaped connecting piece 400 and the connecting plate 300 can be integrally formed by the extrusion process. In addition, when the extrusion direction of the L-shaped connecting piece 400, the side plate 200 and / or the connecting plate 300 is not consistent with the extrusion direction of the panel 100, the L-shaped connecting piece 400, the side plate 200 and / or the connecting plate 300 can be connected to the panel 100 by welding, and the components on the panel 100 which are not integrally formed with the panel 100 can be connected to the adjacent components by welding, and the connection mode includes one or more of spot welding, bubble welding and vertical welding.

[0062] With reference to Figure 1 In some embodiments, the L-shaped connecting piece 400 includes an L-shaped connecting plate, and the L-shaped connecting plate includes a horizontal plate 410 and a vertical plate 420, the vertical plate 420 is provided vertically on the panel 100, and the horizontal plate 410 is opposite and parallel to the panel 100.

[0063] In the present application, the L-shaped connecting plate is prepared from an aluminum alloy profile as an example, the L-shaped connecting plate can be extruded by an extruder at one time, and then cut into a desired length, that is, the horizontal plate 410 and the vertical plate 420 are integrally formed.

[0064] Specifically, the L-shaped connecting plate can be arranged on the long side and / or the short side of the panel 100 according to the construction requirement, i.e. the L-shaped connecting plate is arranged on one side and / or one end of the panel 100 according to the construction requirement, and at this time, the horizontal plate 410 is opposite and parallel to the panel 100.

[0065] With reference to Figures 1 to 3 , in some embodiments, when the template body comprises the panel 100, the side plate 200 and the connecting plate 300, and the L-shaped connecting plate is only one piece and the side plate 200 is two pieces, the vertical plate 420 is connected perpendicularly on one side of the panel 100, the connecting plate 300 is connected perpendicularly on the other side of the panel 100, one of the side plates 200 is connected perpendicularly on one end of the panel 100, the other side plate 200 is connected perpendicularly on the other end of the panel 100, and one end of the side plate 200 is connected perpendicularly with the vertical plate 420 and the other end of the side plate 200 is connected perpendicularly with the connecting plate 300.

[0066] Specifically, in one example, the inside corner connecting template can be a wall-wall surface inside corner connecting template as shown in Figure 2 , at this time, the L-shaped connecting plate corresponds to the first L-shaped connecting plate 14 in Figure 2 , the connecting plate corresponds to the first wall connecting plate 12 in Figure 2 , and the side plate corresponds to the first side plate 13 in Figure 2 ; the first L-shaped connecting plate 14 is connected with one wall template located at the corner, the first wall connecting plate 12 is connected with another wall template located at the corner, and the first side plate 13 is connected with a floor template or a wall-wall surface inside corner connecting template.

[0067] In another example, the inside corner connecting template can be a wall-floor inside corner connecting template as shown in Figure 3 , at this time, the L-shaped connecting plate corresponds to the second L-shaped connecting plate 23 in Figure 3 , the connecting plate corresponds to the second floor connecting plate 24 in Figure 3 , and the side plate corresponds to the second side plate 25 in Figure 3 ; the second L-shaped connecting plate 23 is connected with a wall template located at the corner, the second floor connecting plate 24 is connected with a floor template, and the second side plate 25 is used to extend the floor inside corner connecting template to connect a plurality of floor inside corner connecting templates with each other.

[0068] In another example, the inside corner connecting template can be a long side inside corner template as shown in Figure 1 , at this time, the L-shaped connecting plate is connected with a wall template located at the corner, the connecting plate 300 is connected with a floor template or a wall template, and the side plate 200 is connected with a floor template or a wall-wall surface inside corner connecting template, or the side plate 200 is used to extend the floor inside corner connecting template to connect a plurality of floor inside corner connecting templates with each other.

[0069] In addition, the L-shaped connecting plate, the panel 100 and the connecting plate 300 in the embodiment can be integrally formed, so as to improve the processing efficiency of the internal corner connecting formwork and the subsequent construction efficiency.

[0070] With reference to Figures 4 to 6 In some embodiments, when the formwork body includes the panel 100 and the side plate 200, and the L-shaped connecting plate and the side plate 200 are each only one piece, the vertical plate 420 is vertically connected to one side of the panel 100, and the side plate 200 is vertically connected to the other side of the panel 100.

[0071] Specifically, in one example, the internal corner formwork can be a short-side internal corner connecting formwork as shown in FIG. 1, in which case the L-shaped connecting plate can be connected to the top of the wall formwork, and the side plate 200 can be connected to the floor formwork.

[0084] Specifically, in this case, the internal corner connection template can be as follows: Figure 11 and 12 The keel floor corner connection template shown is suitable for the inside corner of the keel floor. In this case, the L-shaped connecting plate is used to connect the keel body 61 to the wall template, and the connecting ear 62 is used to connect to the keel. To enhance the stability and strength of the connection between the L-shaped connecting plate and the wall template, in another embodiment, the second notch 440 can be sealed by a sealing member 510. Furthermore, in this embodiment, the panel 100 and the two connecting plates 300 are integrally formed.

[0085] Reference Figure 13In some embodiments, when the template body comprises the panel 100 and two side plates 200, and the length of the L-shaped connecting plate is greater than the short side width of the panel 100, the vertical plate 420 of the L-shaped connecting plate is connected perpendicularly to one end of the panel 100, the bottom of the vertical plate 420 of the L-shaped connecting plate extends horizontally with a connecting piece 460, the connecting piece 460 is connected to the side wall of the panel 100 close to the end of the L-shaped connecting plate, and the end of the connecting piece 460 away from the panel 100 extends vertically with a blocking piece 470, and the end of the blocking piece 470 away from the connecting piece 460 is connected perpendicularly to the horizontal plate 410 of the L-shaped connecting plate.

[0086] Specifically, in this case, the internal corner connecting template can be Figure 13 The beam side template in the wall beam internal corner connecting template shown is suitable for the internal corner of the beam side floor connecting part. At this time, the L-shaped connecting plate can be integrally formed with the connecting piece 460, and a notch matched with the end of the panel 100 is punched at one end of the connecting piece 460, so as to be welded and formed with the end wall of the panel 100, the vertical plate 420 of the L-shaped connecting plate and the connecting piece 460. The blocking piece 470 is welded between the L-shaped connecting plate and the connecting piece 460, and the blocking piece 470 is arranged in parallel with the vertical plate 420 of the L-shaped connecting plate. In addition, the panel 100 and the side plate 200 in the embodiment can also be integrally formed.

[0088] Specifically, the side plate 200 and / or the connecting plate 300 and the L-shaped connecting piece 400 of any of the above internal corner connecting templates can be provided with a groove 600 along the length direction of the side plate 200 and / or the connecting plate 300 and the L-shaped connecting piece 400 according to construction requirements, so as to be demoulded subsequently. The pin holes 610 are arranged equidistantly in the groove 600 along the length direction of the groove 600.

[0089] Referring to Figures 1 to 13 In some embodiments, the panel 100 is provided with a reinforcing member 700, the reinforcing member 700 comprises one or more of a reinforcing rib, a reinforcing rib and an inner blocking plate, and when the extrusion direction of the reinforcing member 700 is consistent with the extrusion direction of the panel 100, the reinforcing member 700 is integrally formed with the panel 100.

[0090] Specifically, reinforcement members 700 can be installed on the panel 100 of any of the aforementioned internal corner connection templates according to construction requirements to improve the structural strength of the template. The reinforcement members 700 include at least one of reinforcing ribs, reinforcing ribs, or inner sealing plates, but for the sake of lightweight, generally no more than two types are used. When the reinforcement members 700 include any two of reinforcing ribs, reinforcing ribs, and inner sealing plates, the two types of reinforcement members 700 must be arranged in a staggered manner to ensure structural strength. Moreover, when arranged in a staggered manner, the reinforcing ribs are spot welded to the reinforcing ribs or inner sealing plates, the reinforcing ribs are spot welded to the side plates 200, and the two ends of the reinforcing ribs or inner sealing plates are vertically welded to adjacent components.

[0091] For example, with Figure 1 Taking the reinforcement 700 of the internal corner connection template shown as an example, which includes two reinforcing ribs and three reinforcing bars, the reinforcing ribs and reinforcing bars are arranged perpendicular to each other. One end of the reinforcing rib is connected to the inner wall of the vertical plate 420, and the other end of the reinforcing rib is connected to the inner wall of the connecting plate 300. The distance between the reinforcing ribs can be set according to the length of the panel 100 and the construction requirements. Furthermore, the reinforcing bars can be divided into larger main bars and smaller auxiliary bars. The main bars are set in the middle of the panel 100, and the auxiliary bars are set on both sides of the main bars. The distance between the auxiliary bars and the main bars can be set according to the width of the panel 100 and the construction requirements.

Figure 5 Taking the reinforcement 700 of the corner connection template shown as an example, it includes two first inner sealing plates 414. The two first inner sealing plates 414 are fixedly connected to the fourth panel 413, and the two first inner sealing plates 414 are vertically connected between the two fifth side plates 412.

The third gap 500 can be selected to be provided or not provided according to the specific construction requirements. When it is necessary to enhance the supporting strength of the L-shaped connecting plate, the port of the L-shaped connecting plate can be blocked by the side plate 200 in the form of L, for example, Figure 1 , or the third gap 500 is blocked by the support reinforcing sheet 450 provided on the horizontal plate 410, for example, Figure 4 . In addition, for the case that the height of the vertical plate 420 is higher than the inner sealing plate and a gap is formed between the top wall of the inner sealing plate, the above-mentioned scheme can also be applied, for example, Figure 7 . In the corner connecting formwork, the height of the sixth L-shaped connecting plate 424 is higher than the height of the first inner sealing plate 421, and a gap is formed between the top of the sixth L-shaped connecting plate 424 and the top wall of the first inner sealing plate 421.
