8) and repeating the steps 2) to 7) until the construction of the construction joint 61 is completed.
Specifically, when the formwork hanging device is used, the rotating rod 5 is taken down from the free end of the sleeve 2, the lifting rope 3 is straightened and lifted by the lifting equipment until two sides of the upper surface of the bottom formwork 1 are abutted against the lower surfaces of the two face plates 6 attached to two sides of the construction joint 61 of the building, the upper end of the lifting rope 3 can be fixed on the supports 62 spanned on the two face plates 6 to keep the formwork hanging posture of the bottom formwork 1 and stable, the end formworks are arranged at the ends of two ends of the bottom formwork 1, then concrete grout can be poured, the thickness of the concrete grout is generally parallel and level with the face plates 6, the sleeve 4 can prevent the concrete grout from entering the sleeve 4 to contact the sleeve 2, the sleeve 4 is connected with the end formwork when the concrete grout is solidified, after the requirement of solidification strength is met, the end formwork is removed, the fixed connection between the upper end of the lifting rope 3 and the supports 62 is removed, the rotating rod 5 is connected to the upper end of the sleeve 2, and the bottom formwork 1 can be knocked by the rotating rod 5 downwards (when necessary, the rotating rod 5 is connected and knocked on the sleeves 2 at the two ends in sequence so as to facilitate demoulding), after the bottom template 1 is separated from the lower surface of concrete, the blocking part 52 of the rotating rod 5 is limited by the sleeve 4 due to self weight and the bottom template 1 stops falling, at the moment, the distance from the upper end face of the sleeve 4 to the blocking part 52 is greater than the length of the sleeve 2, the sleeve 2 at the other end is separated from the lower surface of the concrete, and the main rod 51 are driven to drive the sleeve 2 and the sleeve 2 to drive the bottom template 1 by rotating the blocking part 52 and rotating 180 degrees in the horizontal direction, so that the bottom template 1 is moved forwards; lifting the bottom template 1 through the rotating rod 5, sleeving a new sleeve, keeping the template lifting posture of the bottom template 1 through the lifting rope 3, removing the rotating rod 5, arranging a single-ended end standing template in the forward moving direction, and continuously pouring construction; the process is circulated forward until the connection construction of the whole construction joint 61 is completed.
In practice, the detachable connection form between the main rod 51 and the sleeve 2 that can achieve the above-mentioned use effect is various, and is not limited specifically, and will be further described later.
Referring to fig. 1 and 2, the anti-separation clip 32 is connected to the section of the lifting rope 3 outside the free end of the sleeve 2, and when the lifting rope is lifted (in a straightened state), the section of the lifting rope 3 between the anti-separation clip 32 and the end face of the free end of the sleeve 2 has a certain length.
Thus, the hanging rope 3 can be prevented from coming off the sleeve 2 in an abnormal state or when not in use, and the use is facilitated. The section of the lifting rope 3 between the anti-drop clamp 32 and the free end face of the sleeve 2 has a certain length, which is an effective moving amount for keeping the lifting rope 3 to movably pass through the sleeve 2 and the bottom template 1, and avoids interference to influence the connection of the main rod 51 and the sleeve 2.
Referring to fig. 3, an abdicating groove 21 is formed in the inner wall of the sleeve 2 and extends along the axial direction of the sleeve 2 for accommodating the corresponding lifting rope 3 section if necessary, and the abdicating groove 21 extends along the axial direction of the sleeve 2 and at least penetrates through the upper end surface of the sleeve 2.
Like this, can make lifting rope 3 dodge in the groove of stepping down 21, can increase mobile jib 51 and sleeve 2 and can reach the variety of the connection form dismantled of above-mentioned result of use, make things convenient for structural design.
With continued reference to fig. 1, in the present embodiment, a simple and reliable threaded connection is selected, and the detachable connection portions are respectively an internal thread 22 formed on the inner wall of the sleeve 2 and an external thread 511 formed on the main rod 51 so as to connect through the threaded connection, so that when the detachable connection portions are connected through the threaded connection, the corresponding sections of the lifting ropes 3 are retracted into the recess 21.
Wherein, in the axial of sleeve 2, the length of the groove of stepping down 21 on the inner wall of sleeve 2 is not less than the length of internal thread 22, like this, can make things convenient for 3 sections of lifting rope's effective dodging, makes things convenient for bull stick 5 to drive sleeve 2 and rotates. During implementation, the abdicating groove 21 can axially penetrate through the sleeve 2, so that the processing is convenient.
Wherein, the radial direction of the sleeve 2, the depth of the abdicating groove 21 should be larger than the diameter of the lifting rope 3, but the wall breaking is preferably not needed, that is, the wall thickness of the sleeve 2 should be larger than the depth of the internal thread 22 plus the diameter of the lifting rope 3, so as to avoid the wall breaking; of course, in the implementation, the abdicating groove 21 may also penetrate the wall of the sleeve 2, i.e. form a cut, which is convenient for processing and also has little influence on the use strength, but the lifting rope 3 should be prevented from being positioned outside the cut during lifting, so that the lifting rope 3 is easily cut off or worn off by the edge of the groove.
The blocking part 52 is a cross rod 521 vertically connected to the end of the main rod 51 so that the rotating rod 5 is in a T-shaped structure, and the length of the cross rod 521 is greater than the inner hole of the sleeve 4. Thus, the bottom template 1 can be effectively blocked from falling, and the force can be conveniently applied to rotate.
Wherein the upper end surfaces of the sleeve 2 and the sleeve 4 are flush, i.e. of equal length. Therefore, the structural design is more reasonable, the use is more convenient in actual use, and the tool is simpler. Because: if the sleeve 2 is too short and is positioned at the inner end and the lower end of the sleeve 4, the connecting of the rotating rod 5 is inconvenient after the concrete grout is solidified; if the sleeve 2 is too long, the distance from the upper end surface of the sleeve 4 to the stopping part 52 is larger than the length of the sleeve 2, the length of the rotating rod 5 is undoubtedly increased, and the sleeve is inconvenient to use, store and store.
In the implementation, the detachable connection form between the main rod 51 and the sleeve 2 is selected, and through the foregoing description, it can be recognized that, after the sleeve 2 of the main rod 51 is connected, the axial movement of the main rod 51 is relatively limited, and the main rod can rotate synchronously, except for the structural mode in the embodiment, a form shown in fig. 4 can be adopted, the upper end of the inner wall of the sleeve 2 is provided with an L-shaped groove 23, correspondingly, the lower end of the outer circumference of the main rod 51 is provided with lugs (not shown, the lugs correspond to the L-shaped grooves 23, and at least two groups of lugs are required in number), the lugs can enter through the vertical section of the L-shaped groove 23, and then rotate into the horizontal section of the L-shaped groove 23, so as to achieve the effect of limiting the axial movement and rotating synchronously, in this structural mode, the main rod 51 drives the sleeve 2 to rotate in a single direction, but the effects of driving the bottom formwork 1 to, because the detachable connecting part of the matching is the lug and the L-shaped groove 23, the diameter of the main rod 51 can be completely smaller than the inner diameter of the sleeve 2, and thus, the abdicating groove 21 does not need to be specially arranged to abdicate the lifting rope 3, and the form is flexible. Other possible forms of connection are not exhaustive. During implementation, the bottom template 1 can be made of a steel plate, the lifting rope 3 is made of a steel wire rope, the limiting clamp 31 and the anti-falling clamp 32 can be made of the same structural member, metal members are mostly adopted, the sleeve 2 and the rotating rod 5 are also made of metal members, and the sleeve 4 is made of a plastic member.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
