Description

Integral Lifting Shaft Formwork

technical field

The utility model relates to a shaft formwork, in particular to an integral lifting type shaft formwork.

Background technique

Shaft formwork is a steel formwork used for concrete pouring and forming; when performing concrete pouring construction with shafts, holes and other structures, it is necessary to install the shaft formwork first, and after the construction is completed, the shaft formwork needs to be removed and then removed from the shaft.

The defects of the existing shaft formwork are: the integrity is relatively low, the mold needs to be installed during use, and the mold needs to be demoulded after use. The process of mold loading and demoulding is complicated, and the operator needs to enter the shaft to disassemble the formwork by disassembling the bolts. As a result, the pouring quality is not ideal and the pouring speed is slow; the large angle formwork reduces the overall rigidity of the shaft formwork, resulting in a large flatness of the inner wall of the shaft. When the shaft size is less than 1.2×1.2m, due to the small space and large formwork structure, the traditional The template does not meet usage requirements.

Among them, the number of angle steel 6, the number of chute groups, the number of connecting channel steel 9, the number of steel frame planes, the number of horizontal support frames 10, the number of vertical support frames 11, the number of angle molds 7, and the positioning hanging plate 8 The quantity is determined according to the actual situation; the distance between the bottom end of the lower chute 2 and the angle steel 6 where it is located is 30mm-60mm; the slider mechanism can also be connected to the channel steel 9 and the horizontal support frame 10 or Parts of the vertical support frame 11, such as bolts; the width of the angle mold 7: the width of the shaft = 1:23-66; the width of the angle mold 7: the optimal ratio 1:23 of the width of the shaft; the angle mold 7 in the utility model The ratio of the width to the width of the shaft is small, so that the overall rigidity of the utility model is improved, and the flatness of the inner wall of the shaft is small. Even when the size of the shaft is less than 1.2×1.2m, the requirements can be met.

Example 2

As shown in Figures 1-3, the difference between this embodiment and Embodiment 1 is that the planar formwork includes a panel 3; the tops of the eight connecting channel steels 9 are all provided with hanging holes 13, and hanging ropes 14 are passed through the hanging holes 13. Hanging hole 13 and hanging rope 14 are convenient to move the utility model.

As shown in Figures 1-3, the assembly method of the present utility model cross-connects two horizontal support frames 10 and two vertical support frames 11 to complete the assembly of the steel frame plane; The horizontal support end or the vertical support frame 11 ends on the line are connected with the connecting channel steel 9, and then the assembly of the whole inner support frame is completed; the slide pin 12 is positioned in the upper section chute 1 or the lower section chute 2 in the plane formwork, then the completion The installation of plane formwork, the limit of adjacent panel 3 in the plane formwork is connected by a plurality of angle molds 7, then completes the assembling of the present utility model.

Among them, the angle formwork 7 is pressed against the left and right sides of the panel 3; therefore, only the angle formwork 7 and the panel 3 need to be connected by spot welding at the upper, middle and lower points of the panel 3 during actual pouring and installation. To be fixed together, that is, it is only necessary to ensure that the angle mold 7 does not break away from the panel 3 under its own weight.

In the utility model, the angle formwork 7 is very small, and is connected with the plane formwork by spot welding, and is softly connected with the angle formwork 7 by a steel rope when the demoulding is lifted, and when the plane formwork is retracted, the angle formwork 7 Automatically separated from the flat formwork for lifting.

As shown in Figure 1-3, when embodiment 1 and embodiment 2 are in use, in order to allow the utility model to be supported on the shaft that has been poured, it is necessary to place a diameter of Pre-embed the steel pipe at the position of the operation hole of the 30mm embedded part, so as to insert the steel bar into the pre-embedded steel pipe when pouring the next part, and then press the positioning hanging plate 8 at the bottom of the panel 3 in the plane formwork on the steel bar to support the whole formwork For the purpose, when the planar formwork is supported on the steel bars, the overall inner support frame will slide down due to its own weight until the sliding pin 12 reaches the bottom of the lower chute 2, so that the planar formwork is supported in place, and then the angle The formwork 7 and the plane formwork are welded together by spot welding, and then the concrete is poured; the sliding pin 12 in the assembled overall lifting shaft formwork is located at the inner bottom of the lower section chute 2, and when the pouring needs to be demoulded, it needs to be removed by a crane. The rope 14 lifts up the utility model, so that the sliding pin 12 slides from the lower chute 2 to the upper chute 1, because the distance between the bottom of the lower chute 2 and the angle steel 6 where it is located is 30 mm, the plane formwork shrinks inward by 30 mm, When the slide pin 12 was positioned at the inner top of the upper section chute 1, the slide pin 12 would hang the plane formwork, and then the utility model would be lifted upwards until it was fully lifted out of the shaft; 3 will be pulled apart to separate the angle formwork 7 from the plane formwork.
