Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically relating to a variable triangular frame device for casting the zero block of a continuous beam. Background Technology

[0002] In actual construction, most continuous beams are variable height beams. When constructing the zero block of a continuous beam, a triangular frame needs to be placed on top of the support to meet the construction requirements of the height change of the zero block. Most of the existing triangular frames are welded on site, and because the height change curves of different continuous beams are inconsistent, the self-welded triangular frames cannot be reused, which makes construction difficult and economically inefficient.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a variable triangular frame device for casting the zero block of a continuous beam.

[0013] The end of the support rod is provided with a hinge corresponding to the rib plate, and the hinge is provided with a connecting hole corresponding to the adjustment hole, so as to detachably connect the hinge through a pin.

[0014] Preferably, the support rod includes a stud, an upper rod, and a lower rod. The stud has external threads at both ends that are opposite to each other, and is connected to the upper rod and the lower rod respectively by threaded connection.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0025] like Figure 1-3 As shown, this application provides a variable triangular frame device for casting the zero block of a continuous beam. The variable triangular frame device for casting the zero block of a continuous beam can realize the back-and-forth use of the triangular frame between different zero blocks of the continuous beam, thereby ensuring efficient and economical construction.

[0026] The scaffolding device includes an upper chord 1 and a lower chord 2. The upper chord 1 is supported on the casting template on the lower surface of the corresponding continuous beam flange, and the lower chord 2 is supported on a full-span scaffold or other supporting structure. The upper chord 1 and lower chord 2 support the template corresponding to the zero block of the continuous beam, thereby ensuring the casting of the zero block. A limiting support mechanism and a fixed support mechanism are provided between the upper chord 1 and the lower chord 2 to support the upper chord 1 to extend inclinedly in a direction parallel to the lower surface of the continuous beam flange. Both the limiting support mechanism and the fixed support mechanism are adjustable structures to match the construction requirements of the zero block of the variable height beam. In actual construction, depending on the specific site conditions, it can be installed on flat ground. The upper chord 1 and lower chord 2 are positioned on flat ground according to the variable height of the zero block base plate. The limiting support mechanism and the fixed support mechanism are connected to the corresponding positions of the upper chord 1 and lower chord 2 by bolts. After installation, the whole device is hoisted to the corresponding position of the zero block support.

[0027] In this embodiment, the limiting support mechanism includes a support rod 3 hinged between the upper chord 1 and the lower chord 2. The support rod 3 extends to the upper chord 1 in a direction perpendicular to the lower chord 2. The support rod 3 is mainly used to adjust the height of the triangular frame and the inclination angle of the upper chord 1 to adapt to the zero block of the continuous beam with different inclination angles and varying heights. The fixed support mechanism includes three support rods 3 hinged between the upper chord 1 and the lower chord 2. The support rods 3 are mainly used to ensure the support stability of the upper chord 1, so as to ensure that the upper chord 1 will not deform during the pouring process. In the fixed support mechanism, the three support rods 3 are close to each other at one end corresponding to the lower chord 2, and the other end extends to the upper chord 1 in a divergent state. The upper ends of the multiple support rods 3 are divergently distributed to make the upper chord 1 bear a balanced force.

[0028] In this embodiment, the difference between the limiting support mechanism and the fixed support mechanism lies in the number and distribution angle of the support rods 3. The length of the support rods 3 is adjustable to accommodate the increase in the height of the zero block. The support rods 3 include studs 302, upper rods 301 and lower rods 304. The upper rods 301 and lower rods 304 are hollow metal rods. The studs 302 have external threads that are opposite to each other at both ends. The studs 302 have a hexagonal part in the middle. The two ends of the studs 302 are respectively connected to the upper rods 301 and lower rods 304 by threaded connection. The ends of the upper rods 301 and lower rods 304 are provided with hinge positions 303. The hinge positions 303 can be the hinge plates of the corresponding hinge parts 6, so that they are hinged to the hinge parts 6. Thus, the extension and retraction of the support rods 3 can be achieved by rotating the studs 302.

[0029] In one optional embodiment, the upper chord 1 is hinged to one end of the web of the continuous beam with a hinge rod 4. The hinge rod 4 is adjusted according to the inclination angle of the intersection surface of the web and flange of the continuous beam, thereby ensuring all-round support for the continuous beam casting template. The other end of the hinge rod 4 is hinged to the lower chord 2 through a short section 5, extending in a direction parallel to the intersection surface of the web and flange of the continuous beam. In this embodiment, the two ends of the short section are hinged with hinge members 6, which are connected to the hinge rod 4 and the lower chord 2 through the hinge members 6. The length of the short section 5 can be adjustable, and it can be a scaled-down version of the support rod 3; or the short section 5 can be a non-adjustable short section 5, and the support angle of the hinge rod 4 can be adjusted by adjusting different adjustment holes.

[0030] In order to accommodate continuous beams with different flange widths, both the upper chord 1 and the lower chord 2 include a certain lengthening section 7 that is detachably connected to the web of the continuous beam. The lengthening section 7 is spliced ​​by bolts, so as to make adaptive adjustments according to the actual flange width.

[0031] Both the upper chord 1 and the lower chord 2 are provided with multiple adjustment holes evenly distributed along their length direction, so that the specific positions of the limiting support mechanism and the fixed support mechanism can be adjusted according to the width of the wing plate. In this embodiment, the two sets of limiting support mechanisms and the two sets of fixed support mechanisms are distributed between the upper chord 1 and the lower chord 2 at intervals, thereby ensuring the stability of the support.

[0032] In an optional embodiment, the upper chord 1 and the lower chord 2 are each provided with a rib plate 8 extending along their length direction at the middle of their respective sides. The upper chord 1 and the lower chord 2 are respectively adapted to the length of the corresponding rib plate 8. The rib plate 8 is fixed to the corresponding upper chord 1 or lower chord 2 by welding. Adjustment holes are correspondingly provided on the rib plate 8. The end of the support rod 3 is provided with a hinge 6 corresponding to the rib plate 8. The hinge 6 has a U-shaped structure, which is correspondingly engaged with the rib plate 8 and can slide along the rib plate 8. The hinge 6 is provided with a connection hole corresponding to the adjustment hole, so as to detachably connect the hinge 6 through a pin, thereby realizing the need for rapid splicing of this device.

[0033] Furthermore, the structure of the hinge rod 4 is similar to that of the upper chord rod 1, with an angle steel plate provided between the rib plate 8 of the hinge rod 4 and the rib plate 8 of the upper chord rod 1 for hinge connection.

[0034] In an optional embodiment, the length of the support rod 3 is selected by the limiting support mechanism and the fixed support mechanism according to actual needs, based on the actual relative angle and spacing between the upper chord 1 and the lower chord 2.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
