Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a casting formwork for building walls. Background Art

[0002] During the construction of the basement shear wall, it is necessary to ensure the perpendicularity of the shear wall to ensure that the stress characteristics of the final building are not affected. In the actual construction of the existing basement shear wall, generally, formwork support is required for construction. The formwork is enclosed to form a casting chamber for the shear wall. After the steel reinforcement cage tied up is hoisted in the casting chamber, and then tied up again, concrete is poured into the casting chamber enclosed by the formwork by a concrete pump truck until the concrete solidifies to form a stable shear wall. During the actual operation, in order to ensure that the casting chamber is in a vertical state, generally, when supporting the formwork, a vertical coordinate instrument is used for verification. However, during the actual construction process, the operators or equipment often come into contact with the formwork, which may cause the formwork to shift or tilt. Generally, when there is a shift or tilt and the operators cannot detect the problem in time, pouring is directly carried out. Once the formed shear wall exceeds the deviation range, it needs to be demolished, which actually has a significant impact on the construction efficiency and the demolition cost is very high.

The present utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0027] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation.

[0028] The following will, in conjunction with the attached Figures 1 to 6 , give a detailed description of the building wall casting formwork of the present utility model:

[0029] Before introducing the building wall casting formwork, a brief introduction to the existing construction plan is given first. When constructing shear walls in the basement, after the formwork is supported, it is necessary to use a vertical coordinate instrument to detect the perpendicularity of the supported formwork. If there is a deviation, the operator can adjust the formwork until the perpendicularity reaches the set requirements. Then, a steel reinforcement cage is introduced into the formwork cavity, and then retarder concrete is poured. However, during actual operation, it is inevitable that the operator or equipment touches the formwork, resulting in the deflection of the formwork, and ultimately causing the shear wall to deflect beyond the set tolerance. Seriously, it is necessary to demolish the entire constructed shear wall and re-construct. Therefore, the present invention proposes a building wall casting formwork, including a main formwork 10, arranged vertically in two groups at intervals; side formworks 20, arranged vertically on the side parts of the two groups of main formworks 10. The two groups of main formworks 10 and the side formworks 20 enclose a rectangular cavity; a retaining frame 30, attached to the outer side surface of the main formwork 10; adjusting legs 40, connected to the retaining frame 30, and a level adjustment unit is provided on the adjusting legs 40, and the level adjustment unit is used to adjust the level of the adjusting legs 40.

[0030] In one embodiment, referring to Figure 1 and Figure 2 , the two groups of main formworks 10 are overall rectangular plates, and the two groups of side formworks 20 are also rectangular plates. The two groups of main formworks 10 are arranged at intervals, and the two groups of side formworks 20 are installed on both sides of the two groups of main formworks 10. Therefore, the above four groups of formworks can enclose a rectangular cavity. A retaining frame 30 is installed on the outer side surface of the side formwork 20, and the retaining frame 30 is installed on the adjusting legs 40. The level of the adjusting legs 40 is adjusted through the level adjustment unit, and then the verticality of the two groups of side formworks 20 can be adjusted. Once the two groups of side formworks 20 are within the designed verticality range, the entire rectangular cavity can be fixed through the adjusting legs 40, which can avoid the deflection of the rectangular cavity caused by external touch, so that the verticality of the formwork cavity is always within the designed error range. Then, a steel reinforcement cage is introduced into the cavity, fixed simply, and then concrete is poured. It is vibrated by a vibrating rod to eliminate air bubbles. After the concrete solidifies, a qualified shear wall can be formed.

Limiting pieces 122 are provided on the outer walls of the two sets of holding tubes 12, and the limiting pieces 122 abut against the inner side surface of the main formwork 10.

[0035] In one embodiment, the holding notch 11 is opened at the upper end position of the main formwork 10 and is strip-shaped. The clamping plane 121 provided on the outer wall of the holding tube 12 is integrally clamped with the holding notch 11. Thus, when the screw rod 13 is rotated, the limiting pieces 122 of the two sets of holding tubes 12 abut against the inner side of the main formwork 10, and further, the distance between the two sets of main formworks 10 is maintained at a set distance.

[0036] In one embodiment, to facilitate the rotation of the screw rod 13, a screwing nut 131 is provided at the middle position of the screw rod 13.

[0038] In a specific embodiment, when the two sets of main templates 10 are at a set spacing through the two sets of holding tubes 12 and the screw rod 13, by installing the clamping rod 32 and the clamping tube 33, and screwing the clamping nut 34, the two sets of main templates 10 are locked, and the vertical holding plates 31 are tightly attached to the two sets of main templates 10 to ensure the subsequent adjustment of the verticality of the two sets of main templates 10.

[0039] Specifically, a clamping spring 35 is sleeved on the clamping rod 32, and two ends of the clamping spring 35 respectively abut against the tube end of the clamping tube 33 and the inner side surface of the vertical holding plate 31.
