Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Referring to fig. 1, the concrete form supporting apparatus for a road deformation joint according to an embodiment includes a supporting working portion 1; the support device is characterized by further comprising a handheld rotating part 2 connected with the support working part 1 so as to change the support working angle of the support working part 1, wherein the support working part 1 is H-shaped and comprises two parallel and opposite smooth round bar materials 11 which are mostly vertical when in use, and the middle parts of the two smooth round bar materials 11 are fixedly connected through a torque transmission connecting rib 12; handheld rotation portion 2 is the T shape, including extension rod 21 and the rotation handle pole 22 of transversely arranging extension rod 21 one end in, specifically be fixed connection in rotation handle pole 22's middle part, extension rod 21's other end fixed connection in the middle part of passing and turning round splice bar 12, middle partition position department, extension rod 21 is on a parallel with two light circle bar 11.
The supporting device of embodiment, during the use, after two relative end template framves of road movement joint department are erect, can hand supporting device rotate handle lever 22, will support between work portion 1 stretches into the both ends template with the form that is on a parallel with the end template through extension rod 21, rethread rotation handle lever 22's rotation, will support work portion 1 through extension rod 21 and rotate 90, even support work portion 1's biography is turned round and is connected muscle 12 perpendicular to both ends template, and two smooth round bar 11 contacts and supports on both ends template, keep the interval between the template of both ends, guarantee that two templates can not remove in opposite directions and explode the mould when pouring, according to a plurality of this supporting device interval supports of designing requirement and use during actual operation. The supporting device has the advantages of simple structure, effective support, convenient use and disassembly, effective improvement of the construction efficiency, reutilization after disassembly, and cost saving.
The smooth round bar 11 is a smooth round bar, the torque transmission connecting rib 12, the extension rod 21 and the rotating handle rod 22 are screw-thread steel, and the related connection can adopt a welding form.
Therefore, the smooth round steel rod can reduce friction force and is convenient for steering support. All the materials are common and easy to find, and the manufacturing cost is low.
Wherein the rotating handle lever 22 is parallel to the torque transmission connecting rib 12 so that the supporting working part 1 and the handheld rotating part 2 are both positioned on the same plane.
Thus, the operation is further facilitated, because some deformation joints are deeper, the extension rod 21 of the supporting device is longer, the state of the rotation orientation of the supporting working part 1 is not convenient to observe during construction, and after the rotating handle rod 22 is arranged in parallel to the transmission connecting bar 12, the rotating handle rod 22 can be used as an observing part for the orientation state of the supporting working part 1, and the rotation orientation state of the supporting working part 1 can be indirectly judged by observing the orientation of the rotating handle rod 22.
Referring to fig. 4 and 5, the present invention further provides a road deformation joint concrete formwork fixing structure, which includes two cast-in-situ road deformation joint end formworks 3 facing each other in parallel, and further includes a plurality of the above-mentioned road deformation joint concrete formwork supporting devices, all of which are arranged between the two cast-in-situ road deformation joint end formworks 3 at intervals along the length direction of the cast-in-situ road deformation joint end formworks 3, all of the supporting working parts 1 are parallel to each other and supported between the two cast-in-situ road deformation joint end formworks 3 to prevent the opposite movement, that is, the torque transmission connecting bars 12 are perpendicular to the two cast-in-situ road deformation joint end formworks 3, and mainly prevent the opposite movement and mold burst caused by the extrusion of concrete slurry during casting. When the cast-in-place end formwork is implemented, a reinforcement cage is arranged in the corresponding end formwork and is used as a support, and the end formwork and the deformation joint above the end formwork are supported so as to be cast in place.
The effect of the fixing structure is the same as the aforementioned effect, and is not repeated.
Certainly, the supporting device is also flexible in application, if the distance between the templates at the two ends is small, the supporting mode shown in fig. 6 can also be adopted, the transmission and torsion connecting ribs 12 of the supporting working parts 1 are inclined to the end template 3 of the cast-in-situ road deformation joint, the adjacent supporting working parts 1 adopt different inclined angles and enable two adjacent smooth round bar materials 11 to be mutually abutted, and the supporting effect can also be ensured.
In the embodiment shown in fig. 2 and 3, the extension rod 21 may also be a two-segment design, the extension rod 21 is composed of a lower rod segment 211 connected to the torque transmission connecting rib 12 and an upper rod segment 212 connected to the rotating handle rod 22, and the two ends of the lower rod segment 211 and the upper rod segment 212 are in a collinear and opposite to each other and are detachably and synchronously connected in a rotating manner.
In this way, after the support, the upper pole section 212 and the twist grip lever 22 are removed, leaving only the lower pole section 211 and the support working part 1 to act between the two end forms, reducing the impact on the site work after casting. Since the rotating handle bar 22 is usually higher than the construction ground to facilitate the rotating operation, and after the supporting, the field construction (passing) is affected, the sectional design can effectively solve the above problems and reduce the potential safety hazard. In particular, the twist grip lever 22 and the upper lever section 212 can also be used as common parts, i.e. a plurality of lower lever sections 211 and the support working part 1 are used for supporting, but only the same twist grip lever 22 is used during the twist support, thereby saving costs.
Specifically, three parts 213 are processed at the free end of the lower rod section 211, an inner three-part sleeve 214 matched with the three parts 213 is arranged at the free end of the upper rod section 212, and the three parts 213 are inserted into the inner three-part sleeve 214 to realize detachable synchronous rotation connection. Thus, as an alternative form, the support device is suitable for being used when the support device is arranged from bottom to top in bridge deck construction so as to prevent the support working part 1 from falling off; in practice, in order to ensure the integrity of the connection between the lower rod section 211 and the upper rod section 212 and prevent the connection from being easily disconnected, retractable elastic hemispheres (not shown) protruding from the side walls of the three parts 213 can be arranged on the three parts 213 to form clamping pins, and corresponding hemispherical grooves are arranged on the inner wall of the inner three-part sleeve 214, so that the elastic hemispheres can fall into the hemispherical grooves to realize clamping and embedding through retraction and ejection in the process that the three parts 213 are inserted into the inner three-part sleeve 214.
In implementation, the outer sides of the two smooth round bars 11 are respectively connected with minor arc-shaped cylindrical plates 13 in parallel, the two cylindrical plates 13 are equal in diameter and coaxial, that is, located on the same cylindrical surface, and the extension rod 21 is the axis of the two cylindrical plates 13.
Therefore, the operation is further simplified, the supporting contact action area is larger, the state that the standard torque transmission connecting rib 12 is perpendicular to the templates at the two ends does not need to be completely rotated, and effective supporting can be realized as long as the outer arc surfaces of the two column panels 13 are effectively contacted with the templates at the two ends, as shown in fig. 7.
Referring to fig. 2 and 3, in practice, the sections near the two ends of the rotating handle bar 22 are respectively sleeved with a protective bushing 23 for holding in use. In practice, since the lower rod segment 211 may be grasped due to the segmented arrangement, a similar protective sleeve 23 may be added to the upper end of the lower rod segment, as shown in fig. 8.
With reference to fig. 8, due to the different depths of the deformation joints, the extension rod 21 is not limited to a two-segment design, but can be divided into a plurality of segments to be connected in a detachable and synchronous rotation manner, so as to adjust the length thereof and adapt to the corresponding construction. In addition, for more stability during rotation, a torque transmission connecting rib 12 can be additionally arranged between the two smooth round bar materials 11, the two torque transmission connecting ribs 12 are respectively close to the end parts of the smooth round bar materials 11, and the lower end of the extension rod 21 is fixedly connected with the two torque transmission connecting ribs 12 at the same time.
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.
