Problems solved by technology

At present, most construction projects often use simple wooden formwork assembly when constructing inclined columns. This formwork is only assembled in a circular form on the outer facade. There are several problems in the concrete pouring process: 1. Because It is a simple assembly of wooden formwork, the joints are not tight, and it is easy to leak grout, which affects the appearance of concrete molding; 2. With the increase of concrete load, the wooden formwork slowly deforms, and finally the column deforms accordingly; 3. Since the cylindrical wooden formwork is assembled , resulting in difficult fixation, and the support is often easily damaged and deformed; 4. Pouring quality of slanted columns and high repair and rework rate; 5. Safety accidents are prone to occur during pouring of slanted columns, which has a great impact on safe and civilized construction

Embodiment 1

[0025] Such as figure 1 , figure 2 As shown, in this embodiment, a cylindrical formwork fixing device includes two semicircular hoops 1 and connecting plates 2 arranged at both ends of the hoops 1. On the connecting surface, one of the connecting surfaces is provided with a positioning hole 5, and the other is provided with a positioning shaft 6. The axes of the positioning hole 5 and the positioning shaft 6 are arranged symmetrically with the axis of the hoop 1, and the connecting plate 2 is provided with screws hole.

[0026] After the cylindrical formwork is built, use two hoops 1 to hold the cylindrical formwork tightly so that the connecting surfaces of the two hoops 1 are aligned, and the connecting surface of one hoop 1 with the positioning hole 5 is aligned with the other hoop 1 with the positioning hole 5. The connecting surface of the shaft 6 is corresponding, so that the positioning shaft 6 is packed into the positioning hole 5 . Then use screws 3 and nuts 4 to ...

Embodiment 2

[0029] On the basis of the above embodiments, in this embodiment, the hoop 1 includes several hoop units 9 hinged to each other. In this way, the diameter of the hoop 1 can be adjusted according to the diameter of the cylindrical formwork, so that the hoop 1 can be closely attached to the cylindrical formwork with different diameters, and the scope of application of the hoop 1 is increased.

[0030] After the corresponding diameter of the hoop 1 increases, the distance between the corresponding connecting plates 2 on the two hoops 1 will also increase. At this time, a gasket 7 can be added between the two connecting plates 2 to eliminate the gap between the connecting plates 2. The gap can enhance the locking effect of the screw 3 on the connecting plate 2, thereby enhancing the stability of the hoop 1 and the locking effect of the hoop 1 on the cylindrical formwork.

[0031] When the distance between the corresponding connecting plates 2 on the two hoops 1 is relatively large...

Embodiment 3

[0034] On the basis of the above embodiments, in this embodiment, the diameter of the positioning hole 5 is larger than the diameter of the positioning shaft 6 . In this way, the assembly of the positioning hole 5 and the positioning shaft 6 is facilitated, thereby facilitating rapid positioning, and avoiding the problem that the positioning hole 5 and the positioning shaft 6 cannot be aligned due to machining errors, deformation and the like. The connecting plate 2 is hinged with the hoop 1 so that the corresponding two connecting plates 2 are always kept parallel, so that the positioning hole 5 and the positioning shaft 6 can also be aligned all the time.

Abstract

The invention discloses a cylindrical formwork fixing device and a fixing method. The cylindrical formwork fixing device comprises two semicircular hoops and connecting plates arranged at the two ends of each hoop, connecting faces coplanar with the axis of the hoops are arranged on the connecting plates, a positioning hole is formed in one connecting face, a positioning shaft is arranged on the other connecting face, the axis of the positioning hole and the axis of the positioning shaft are symmetrically arranged with the axis of the hoops as the symmetry axis, and screw holes are formed in the connecting plate. The cylindrical formwork fixing devices and the fixing method have the beneficial effects that the hoops can bu utilized to apply inward pressure in the radial direction to a cylindrical formwork in the circumferential direction of the cylindrical formwork, the circumferential stress of the cylindrical formwork is uniform, the position precision of the cylindrical formwork can be advantageously kept, the impact resistance of the cylindrical formwork is improved, and deformation of the cylindrical formwork under the impact effect of concrete is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cylindrical formwork fixing device and a fixing method. Background technique [0002] Under the existing technical conditions, there are more and more special-shaped buildings, and the difficulty of construction is also increasing. For example the construction of inclined columns. At present, most construction projects often use simple wooden formwork assembly when constructing inclined columns. This formwork is only assembled in a circular form on the outer facade. There are several problems in the concrete pouring process: 1. Because It is a simple assembly of wooden formwork, the joints are not tight, and it is easy to leak grout, which affects the appearance of concrete molding; 2. As the concrete load increases, the wooden formwork slowly deforms, and finally the column deforms accordingly; 3. Since the cylindrical wooden formwork is assembled , resulting i...
