Detailed Description
The present utility model will be described in further detail with reference to test examples and specific embodiments. It should not be construed that the scope of the above subject matter of the present utility model is limited to the following embodiments, and all techniques realized based on the present utility model are within the scope of the present utility model.
Example 1
According to the concrete pouring formwork device disclosed by the utility model, as shown in fig. 1, the first fixing piece 3 and the connecting piece 4 are arranged to be matched, and the formwork 1 required in pouring of the side wall 8 is quickly fixed in a pre-buried and back-pulled combined mode, so that the construction efficiency is improved.
The concrete pouring formwork device comprises a supporting structure 2, a formwork 1, a first fixing piece 3 and a plurality of connecting pieces 4 embedded in the supporting structure 2. In order to fix the template 1, one surface of the template 1 is attached to the first fixing piece 3, and the bottom end of the other surface is attached to the supporting structure 2, so that two sides of the template 1 are fixed. After the fixing of the formwork 1, the first fixing members 3 are in a relatively free state, and therefore, in order to fix the first fixing members 3, the connecting members 4 are connected to the first fixing members 3, wherein one end of each connecting member 4 is connected to the supporting structure 2 and the other end is connected to the first fixing member 3. As shown in fig. 2, the formwork 1 is parallel to the first support 21, and a plurality of connecting pieces 4 are arranged at the top end for connecting the formwork 1, the support structure 2 and the side supports 9, so that a cavity 6 with an upward opening is formed by combining the formwork 1, the support structure 2 and the side supports 9, and concrete is poured above the cavity 6, thereby forming the side wall 8. The side supports 9 may be steel reinforced concrete templates or composite templates, and if the side walls are poured on both sides, the poured side walls may be used as the side supports 9.
As shown in fig. 3, the supporting structure 2 is based on the existing side wall 8, so that the first fixing member 3 is pulled back through embedding, and therefore, a poured wall body is adopted as the supporting structure 2, in order to reserve the cavity 6 in front of the supporting structure 2 and the formwork 1, the supporting structure 2 should comprise two parts, one part is in co-action with the formwork 1, two sides of the side wall 8 are required to be abutted with the bottom of the formwork 1 when pouring, and the other part is required to be abutted with the bottom of the formwork 1, so that the part of the supporting structure 2 in co-action with the formwork 1 is separated, and meanwhile, the supporting structure 2 is required to comprise a first support 21 and a second support 22 as a substrate for pouring the side wall 8.
Then, if the vertical section is a section perpendicular to the wall surface and cut off in the height direction of the wall surface, the vertical section of the support structure 2 formed by combining the first support 21 and the second support 22 is necessarily L-shaped. Wherein the first support 21 is parallel to the formwork 1 and is higher than the formwork 1; the second support 22 is abutted with the bottom end of the template 1, and the template 1, the first support 21 and the second support 22 are combined to form the inner wall of the cavity 6. Of these three inner walls, the first support 21 and the formwork 1 are a set of parallel sides constituting two parallel sides of the cavity 6, and the second support 22 forms one side of the cavity 6 opposite to the open side. Since the first support 21 is typically a side wall 8 that has been cast, the second support 22 is typically a bottom plate or a side wall 8 that has been cast. Therefore, the height of the formwork 1 is smaller than the height of the first support 21, and according to the short slab effect, the poured side walls 8 should not be higher than the formwork 1.
The current common fixing mode of the formwork 1 is usually to fix the spliced portion by using square timber or similar structural members, wherein the structural members used for fixing the spliced portion of the formwork 1 are second fixing members 5, the second fixing members 5 are arranged between the formwork 1 and the first fixing members 3 along the length direction of the formwork 1, all the second fixing members 5 are equally spaced and parallel to each other, and the spacing between the second fixing members is equal to the distance between two adjacent spliced portions on the formwork 1, that is, all the second fixing members 5 are strip-shaped structural members arranged at the spliced portions of two adjacent formworks 1. The second fixing member 5 is made of steel structural members or wooden structural members according to the material of the formwork 1. When the template 1 is Yi Ante template 1, the second fixing piece 5 is made of steel structural members; when the template 1 is made of wood, the second fixing member 5 is made of a wooden structural member, and the wooden structural member is precisely square wood.
As shown in fig. 4 and 5, in order to fix the first fixing member 3, the connection member 4 is designed according to the characteristics of the support structure 2 and the first fixing member 3. Since the connecting member 4 is connected to the support structure 2 by the connecting member 4 being connected to the first support 21 and the second support 22, respectively, the connecting member 4 includes a first connecting member 41 and a second connecting member 42, and one end of the first connecting member 41 is connected to the first fixing member 3, and the other end is connected to the first support 21; the second connecting member 42 has one end connected to the first fixing member 3 and the other end connected to the second support 22.
The first connecting piece 41 comprises a first pre-embedded end 411 and a first connecting end 412; the first embedded end 411 is partially embedded in the first support 21, and the first embedded end 411 is embedded in the first support 21 to a depth, so that the pulling-resistant force of the first embedded end can bear the force transferred to the first fixing piece 3 when the side wall 8 is poured. The first connecting end 412 penetrates through the first fixing member 3 and then is attached to the first embedded end 411, and the connector 43 connects the first and second fixing members.
The second connecting piece 42 includes a second pre-buried end 421 and a second connecting end 422; the second support 22 is provided with a second embedded end 421, and the second connection end 422 penetrates through the first fixing piece 3 and is connected with the second embedded end 421 through the connector 43.
Since the second support 22 abuts against the bottom end of the formwork 1, the second embedded end 421 is preset before the back-pull structure is set, and therefore, the length of the second embedded end 421 cannot exceed the second support 22. Thus, on the side of the second embedded end 421 facing the first fixing plate, a sleeve 44 is partially provided. The connector 43 connecting the second connection end 422 to the second embedded end 421 is also disposed in the sleeve 44, i.e. the sleeve 44 is wrapped around the connector 43.
Meanwhile, in order to fix the other end of the connecting piece 4 penetrating through the first fixing piece 3, a fixing device 7 is arranged, and the fixing device 7 is sleeved on the connecting piece 4 and abuts against one surface, away from the template 1, of the first fixing piece 3. The fixing device 7 is sleeved at the first connecting end 412 or the end of the second connecting end 422 which is not connected with the connector 43, and is clung to the first fixing piece 3, the second connecting end 422 and the first connecting end 412 are fixed, that is, the fixing device 7, the supporting structure 2 and the connector 43 work together to control the movement of the connecting piece 4, so that the first fixing piece 3 is completely fixed, meanwhile, the supporting structure 2 provides a pulling force for the first fixing piece 3, and the force applied to the template 1 by concrete grout is borne when the side wall 8 is poured.
The beneficial effects of this embodiment are: according to the concrete pouring formwork device, the first fixing piece 3 is fixed in the supporting structure 2 in a back-pull mode through the embedded connecting piece 4, so that the first fixing piece 3 can be used for quickly fixing the formwork 1. The formwork supporting device with the structure is simple in structure, convenient to operate, and excellent in fixing performance of the formwork 1, and fully utilizes the existing environment foundation.

in the preparation state, the back-pull structure comprises a semi-closed cavity 6 formed by combining the support structure 2 and the template 1. When the first fixing piece 3 is made of double-spliced I-steel, the I-steel is processed according to two types of 5m and 6m, wherein the casting height of the single side wall 8 with the specification of 5m is not more than 4m, and the casting height of the single side wall 8 with the specification of 6m is not more than 4.5m.
As shown in fig. 6, if the dimension of the first fixing member 3 is 6m and the casting height of the side wall 8 is required to reach 4.5m, the second connecting member 42 will necessarily pass through the formwork 1; as shown in fig. 6, if the first fixing member 3 has a specification of 5m and the casting height of the side wall 8 only needs to reach 4.5m, the second connecting member 42 will not pass through the formwork 1.
In the working state, as shown in fig. 7, concrete is poured in the cavity 6, and then a side wall 8 is formed between the support structure 2 and the formwork 1.
The beneficial effects of this embodiment are: according to the wall system, the formwork supporting device of the embodiment 1 is arranged, so that the side wall 8 is poured, and compared with the original side wall 8 pouring, the construction efficiency is slower because the formwork 1 is not fixed in place, and the wall system can be used for quickly and reliably fixing the formwork 1 in a mode of combining pre-burying and back-pulling, so that the construction time is shortened, and the construction efficiency is effectively improved.
