[0003] The cantilever frame adopts I -beam base, and during construction, it is necessary to reserve an I -beam hole at the low wall, and after the hole cantilever frame is removed, a formwork needs to be erected at the hole for pouring concrete;

[0004] The formwork outside the hole is generally reinforced by nailing into the already poured concrete or by using a clamp body composed of a screw rod and a steel pipe; the inside is more complex than the outside, and a concrete feeding hopper needs to be added to the outside formwork system, which is reinforced by a similar outside formwork system. The above-mentioned formwork reinforcement system has the following problems:

[0005] (1) Nails are used for fixation, and it is difficult to nail into the concrete, and the formwork and wall surface are easily damaged during removal;

[0033] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered below.

[0034] Please refer to Figures 1-6 The present application provides a technical scheme: a low wall hole pouring template mounting bracket, comprising a horizontal unit for supporting on the top surface of the low wall and a vertical unit for mounting the template 1; the vertical unit is provided with two, for respectively mounting the template 1 on the inner side of the low wall and the template 1 on the outer side of the low wall; the horizontal unit is connected with the two vertical units to fix the distance between the two vertical units, and is used for hanging the two vertical units on the inner side of the low wall and the outer side of the low wall respectively, so that the templates 1 mounted on the two vertical units abut on the hole position on the inner side of the low wall and the hole position on the outer side of the low wall one by one;

[0035] The horizontal unit is supported on the top surface of the low wall, and the two vertical units are connected with the horizontal unit, so that the two vertical units can be hung on the inner side and the outer side of the low wall through the horizontal unit. Based on this effect, the two templates 1 are respectively mounted on the two vertical units, so that the templates 1 on the inner side and the outer side of the low wall are at the same height as the holes on the low wall. At the same time, the horizontal unit can also fix the distance between the two vertical units. According to the thickness of the low wall, the distance between the two vertical units is fixed, so that the template 1 on the vertical unit can tightly abut on the inner side or the outer side of the low wall. Therefore, the two templates 1 can be abutted on the inner side and the outer side of the low wall through the cooperation of the two vertical units and the horizontal unit, so that the template 1 can provide support for the concrete when pouring the hole on the low wall;

[0036] The present application utilizes the low height of the low wall to hang the formwork 1 on the low wall through the support to realize the fixation of the formwork 1, without damaging the wall to install the formwork 1, and the removal is more convenient, without threading the counter-pulling screw rod in the hole of the low wall, improving the waterproof performance of the final formed wall, and the structure is simple, convenient to use and can be repeatedly used.

[0037] Specifically, the vertical unit includes a vertical rod 21, and the vertical rod 21 is provided with a mounting unit for fixing the formwork 1, such as Figure 1 As shown, when the vertical rod 21 is hung on the inner side or the outer side of the low wall through the horizontal unit, the vertical rod 21 is vertically downward, and the length of the vertical rod 21 is designed according to the distance from the hole on the low wall to the top surface of the low wall, so that the formwork 1 mounted on the vertical rod 21 can be the same height as the hole on the low wall, and the formwork 1 is fixed on the vertical rod 21 through the mounting unit on the vertical rod 21;

[0038] Specifically, as shown in the figure, Figure 1 The mounting unit includes two clamping pieces 22 mounted on the vertical rod 21 and used for clamping the formwork 1 from the opposite sides of the formwork 1, the formwork 1 is clamped from the left and right sides or the upper and lower sides of the formwork 1 through the two clamping pieces 22, so as to realize the fixation of the formwork 1 on the vertical rod 21, and at the same time, when the formwork 1 is fixed through the clamping piece 22, the side surface of the vertical rod 21 can be in contact with the front end surface of the formwork 1, and the rear end surface of the formwork 1 is used for contacting the cast concrete, the vertical rod 21 provides lateral support for the formwork 1, which is used for resisting the lateral pressure of the concrete during casting, increasing the stability of the formwork 1, and improving the surface quality after the hole plugging on the final low wall is completed;

[0039] Specifically, the two clamping pieces 22 are relatively arranged in the vertical direction, and are used for clamping the formwork 1 from the upper and lower sides of the formwork 1, which can prevent the formwork 1 from falling and improve the stability of the formwork 1 after installation;

[0040] Further, at least one of the two clamping pieces 22 is in sliding fit with the vertical rod 21 along the length direction of the vertical rod 21, and the clamping piece 22 in sliding fit with the vertical rod 21 is threadedly connected with a fastening bolt 23 used for abutting against the surface of the vertical rod 21 and fixing the position of the clamping piece 22 on the vertical rod 21;

[0041] As shown in the figure, Figure 1 When one clamping piece 22 is slidingly arranged on the vertical rod 21, the fastening bolt 23 can fix this clamping piece 22 at any position within the stroke thereof, so as to change the spacing between the two clamping pieces 22, and correspondingly, in the actual use process, different heights of the formwork 1 can be clamped on the vertical rod 21 through the spacing adjustment of the two clamping pieces 22, since the formwork 1 is usually cut from a wooden board and there is no strict size requirement during cutting, therefore, the setting of one clamping piece 22 sliding along the vertical rod 21 can better adapt to the actual situation, and the formwork 1 can also be stably fixed when the size of the formwork 1 deviates.

[0042] As shown in Figure 2 , when the two clamping pieces 22 are both slidingly arranged on the vertical rods 21, not only the spacing between the two clamping pieces 22 is adjustable, but also the position of the formwork 1 on the vertical rods 21 can be adjusted by moving the two clamping pieces 22. The height of the low wall on different buildings may be different, which leads to the change of the distance from the hole on the low wall to the top surface of the low wall. When the position of the formwork 1 on the vertical rods 21 is adjustable, it can adapt to low walls of different heights within a certain range, thereby increasing the applicability of the support;

[0043] Specifically, as shown in Figure 3 , the clamping piece 22 is sleeved on the vertical rod 21 through a frame matching the cross-sectional shape of the vertical rod 21, so that the clamping piece 22 can be slidingly fitted with the vertical rod 21. The frame is threadedly engaged with the fastening bolt 23, thereby realizing the position fixation of the clamping piece 22 on the vertical rod 21.

[0044] Each vertical unit includes a plurality of vertical rods 21, and the plurality of vertical rods 21 are parallel to each other. Each vertical rod 21 is provided with a mounting unit, or a plurality of vertical rods 21 are provided with a mounting unit. The plurality of vertical rods 21 can collectively provide lateral support force for the formwork 1, thereby increasing the stability of the formwork 1 during use.

[0045] As shown in Figure 5 , in this example, the vertical unit includes two vertical rods 21, and the two vertical rods 21 are provided with a mounting unit. The two ends of the clamping piece 22 are connected to the two vertical rods 21, respectively. The clamping piece 22 clamps the formwork 1 from the upper side and the lower side of the formwork 1. When the clamping piece 22 is adjusted, the height of the clamping piece 22 on the different vertical rods 21 can be ensured to be the same, thereby preventing the clamped formwork 1 from being in an inclined state.

[0046] Further, as shown in Figure 4 , the clamping piece 22 includes a first contact surface 221 for contacting the side surface of the formwork 1 to clamp the formwork 1, and a second contact surface 222 for contacting the end surface of the formwork 1 to support the formwork 1. The first contact surface 221 of the two clamping pieces 22 contacts the side surface of the formwork 1 to clamp the formwork 1. The second contact surface 222 contacts the front end surface or the rear end surface of the formwork 1 to provide lateral support for the formwork 1. The clamping assembly can provide lateral support for the formwork 1 in the area outside the vertical rod 21, thereby further increasing the bending strength of the formwork 1 and preventing the position of the formwork 1 not supported by the vertical rod 21 from being deformed in the pouring process.

[0047] Specifically, the length of the first contact surface 221 along the thickness direction of the template 1 is not greater than the thickness of the template 1. When the template 1 is clamped by the clamping piece 22, the first contact surface 221 is in contact with the side surface of the template 1, and the second contact surface 222 is in contact with one of the end surfaces of the template 1. When the distance from the edge of the first contact surface 221 farthest from the second contact surface 222 to the second contact surface 222 is greater than the thickness of the template 1, the clamping piece 22 will protrude from the other end surface of the template 1, that is, the clamping piece 22 will be in contact with the inner side surface or the outer side surface of the low wall before the template 1, which makes the template 1 unable to tightly abut against the inner side surface or the outer side surface of the low wall. Therefore, the distance from the edge of the first contact surface 221 farthest from the second contact surface 222 to the second contact surface 222 must be not greater than the thickness of the template 1, so as to prevent the clamping piece 22 from protruding from the end surface of the template 1 towards the low wall after the template 1 is fixed.

[0048] Figure 1 A first example of a transverse unit is shown. In this example, the transverse unit includes a horizontal rod 31, one vertical rod 21 in one vertical unit is installed at a first end of the horizontal rod 31, and one vertical rod 21 in another vertical unit is installed at a second end of the horizontal rod 31. The horizontal rod 31 is placed horizontally on the top surface of the low wall to achieve the hanging of the vertical rods 21 on the inner side and the outer side of the low wall. When the vertical rods 21 are fixed on the horizontal rod 31, the distance between the two vertical units is fixed, which can be suitable for low walls with a fixed thickness. When used on low walls with different thicknesses, a whole bracket needs to be re-made to adapt to low walls with different thicknesses. When the vertical rods 21 are detachably installed on the horizontal rod 31, the vertical rods 21 can be detached from the horizontal rod 31 and then assembled on the horizontal rod 31 matched with the thickness of the low wall. When facing low walls with different thicknesses, only the horizontal rod 31 needs to be replaced, and the application range is relatively wider.

[0049] Figure 2 A second example of a transverse unit is shown. In this example, the transverse unit includes adjusting screws 32, the number of the adjusting screws 32 is the same as the number of the vertical rods 21 in the vertical units, and the adjusting screws 32 are correspondingly arranged in the vertical rods 21 at positions corresponding to the two vertical units and are in sliding fit with the vertical rods 21. Two adjusting nuts 33 for adjusting the sliding stroke of the vertical rods 21 on the adjusting screws 32 are threadedly connected to each adjusting screw 32. The adjusting screws 32 are placed horizontally on the top surface of the low wall to achieve the hanging of the vertical rods 21. When used, the adjusting nuts 33 on the adjusting screws 32 are pressed against one side of the vertical rods 21 away from the low wall, and the two vertical rod 21 units are pressed against the low wall from both sides to achieve the abutment of the template 1 and the low wall. At the same time, low walls with different thicknesses in a certain range can be adapted, and when facing low walls with different thicknesses, the whole bracket or the transverse unit does not need to be replaced. When installing the whole bracket, the height of the template 1 can be first lowered in place, and then the distance between the two vertical units is adjusted, which is more convenient to use.

[0050] Preferably, in the present example, the top of the vertical rod 21 in the vertical unit is fixedly connected by a cross beam, and the adjusting screw 32 is arranged in the cross beam, and the number of the adjusting screw 32 can be different from the number of the vertical rod 21 in the vertical unit.

[0051] As shown in the drawings, in some examples, the top end of the vertical rod 21 is provided with a bent portion 211 for contacting the top surface of the low wall, and the bending portion 211 at the top of the vertical rod 21 can increase the bending strength of the vertical rod 21, and further increase the lateral support force of the vertical rod 21 to the formwork 1. Figure 2

[0052] When the top of the vertical rod 21 is provided with the bent portion 211, the vertical rod 21 can be hung on the low wall by itself, and at this time, the horizontal unit can be further optimized, Figure 6 A third example of the horizontal unit is shown, in which the top of the vertical rod 21 has a bent portion 211, and the horizontal unit includes a mounting seat 34 and two clamping blocks 35 arranged on the same surface of the mounting seat 34, one of the two clamping blocks 35 abuts against the surface of the vertical rod 21 away from the low wall arranged on the inner side of the low wall, and the other abuts against the surface of the vertical rod 21 away from the low wall arranged on the outer side of the low wall, and the two clamping blocks 35 are used to press the two vertical units on the low wall from the horizontal direction, and since the vertical rod 21 can be hung on the low wall by the bent portion 211 at this time, it is only necessary to fix the spacing between the vertical rod 21 on the inner side of the low wall and the vertical rod 21 on the outer side of the low wall, and the fixing of the vertical rod 21 and the formwork 1 can be completed, and the two clamping blocks 35 on the mounting seat 34 can press the vertical rod 21 on the inner side of the low wall and the vertical rod 21 on the outer side of the low wall on the low wall, and the bracket is more simple and convenient to use.

[0053] Further, at least one of the two clamping blocks 35 on the mounting seat 34 is adjustable in position on the mounting seat 34, so that the spacing between the two clamping blocks 35 is adjustable, thereby adapting to low walls of different thicknesses, and specifically, Figure 6 As shown in the drawings, the clamping block 35 is provided with a fastening screw, and the mounting seat 34 is provided with a sliding groove for sliding the fastening screw, and the fastening screw on the clamping block 35 is screwed through the sliding groove and threadedly engages a nut, and the clamping block 35 is fixed by the frictional force of the nut abutting against the mounting seat 34, thereby realizing the adjustable position of the clamping block 35 on the mounting seat 34.

[0054] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
