[0002] With the acceleration of the pace of urban construction in my country, the construction progress and quality of the municipal industry are constantly improving, and the construction cost is increasing rapidly. Due to the convenience of formwork construction, people are increasingly favoring it. Municipal engineering construction involves the installation of the box beam oblique structure formwork, but the current formwork top supports on the market are all vertical, and it is impossible to set up oblique top supports to support the main beams of the oblique web and flange plate formwork. Utility Model Content

[0003] In order to overcome the defects of the prior art, an adjustable top support for a formwork suitable for an oblique structure of a municipal box girder is provided, which can solve the problem that the existing top support cannot be rotated obliquely to support the main beam of the oblique web and flange plate formwork.

[0004] In order to achieve the above technical effects, the solution provided by the utility model is to provide an adjustable top support for a formwork suitable for an oblique structure of a municipal box beam, which includes:

[0005] A screw, wherein a sphere is provided at the top of the screw;

[0006] A top support located above the screw rod, wherein a square column is provided on the bottom surface of the top support, and a receiving groove for receiving the sphere is provided in the square column;

[0007] A limiting mechanism for limiting the rotation of the jacking support comprises an internal threaded sleeve screwed on the screw rod, and a support rod connected to the internal threaded sleeve and parallel to the screw rod, wherein the support rod is supported on the bottom surface of the jacking support.

[0008] Preferably, a slide rail matching the end of the support rod is provided on the bottom surface of the top support, and the end of the support rod is slidably connected in the slide rail.

[0009] Preferably, the slide rail is arranged on one side of the square column and the length direction of the slide rail is the same as the length direction of the jacking support.

[0010] Preferably, the side wall of the internally threaded sleeve is vertically connected with an ear plate, the support rod is a threaded rod, the support rod is passed through the ear plate and is threaded with a nut.

[0011] Preferably, the number of the nuts is two, and the two nuts are respectively screwed on the bottom and the top of the ear plate.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 As shown, the embodiment of the utility model provides an adjustable top support for a formwork applicable to an inclined structure of a municipal box beam, comprising a screw 1, a top support 4, and a limit mechanism. Among them:

[0024] like Figure 3 As shown, a ball 3 is provided at one end of the screw 1. Figure 2 As shown, the top support 4 is located above the screw rod 1, and a square column 5 is provided on the bottom surface of the top support. The square column 5 is provided with a receiving groove for receiving the ball 3.

[0025] like Figure 1 , Figure 4 As shown, the limiting mechanism includes an internal threaded sleeve 6 screwed on the screw rod 1, and a support rod 7 connected to the internal threaded sleeve 6 and parallel to the screw rod 1, and the support rod 7 is supported on the bottom surface of the top support 4. The limiting mechanism is used to limit the rotation of the top support 4. The internal threaded sleeve 6 moves up and down on the screw rod 1, thereby driving the support rod 7 to move up and down, and the support rod 7 will drive the top support 4 to rotate clockwise and counterclockwise during the up and down movement. In order to ensure that the top support 4 does not separate from the screw rod 1 when rotating, it is necessary to make the top support 4 tilt only to one side of the support rod 7 (that is, tilted to the left side in Figure 1), that is, the limit state of the upward movement of the screw rod 1 is to keep the top support 4 horizontal.

[0026] As a preferred implementation, Figure 2 As shown, a slide rail 8 matching the end of the support rod 7 is provided on the bottom surface of the top support 4 , and the end of the support rod 7 is slidably connected in the slide rail 8 .

[0027] As a preferred embodiment, the slide rail 8 is arranged on one side of the square column 5 and the length direction of the slide rail 8 is the same as the length direction of the top support 4. Specifically, the support rod 7 slides in the slide rail 8 during the up and down movement. When the support rod 7 moves down, the support rod 7 slides outward in the slide rail 8 and drives the top support 4 to rotate downward in the counterclockwise direction to a certain angle. When the support rod 7 moves up, the support rod 7 slides inward in the slide rail 8 and supports the top support 4 to rotate upward in the clockwise direction to a certain angle, and the upper limit position of the support rod 7 is to make the top support 4 horizontal.

[0028] As a preferred implementation, Figure 4As shown, the side wall of the internal threaded sleeve 6 is vertically connected with an ear plate 10, and the support rod 7 is a threaded rod. The support rod 7 is inserted into the ear plate 10 and is screwed with a nut 9.

[0029] As a preferred embodiment, there are two nuts 9, which are respectively screwed on the lower side and the upper side of the ear plate 10. The nuts 9 can be adjusted to allow the support rod 7 to move up and down.

[0030] As a preferred embodiment, the cross section of the top support 4 is U-shaped, and the opening of the top support 4 faces upward.

[0031] As a preferred embodiment, an adjusting nut 2 is screwed on the screw rod 1, and the adjusting nut 2 is arranged below the internal threaded sleeve 6, and the adjusting nut 2 has two supporting ears. When the jacking support is in use, the position below the adjusting nut 2 of the screw rod 1 will be inserted into the upper part of the scaffolding upright, and the supporting ears will be blocked at the top of the scaffolding upright, so that the screw rod 1 is fixed to the upper part of the scaffolding upright. Since the lower part of the screw rod 1 is inserted into the scaffolding upright, the supporting height of the jacking support 4 is the distance between the adjusting nut 2 and the jacking support 4. The adjusting nut 2 moves on the screw rod 1 to change the distance between the adjusting nut 2 and the jacking support 4, thereby further adjusting the supporting height of the jacking support 4.

[0032] The utility model is suitable for the adjustable top support of the formwork of the municipal box beam oblique structure. The top support 4 can be rotated in the square column 5 through the ball 3, so as to rotate freely relative to the screw 1. The support rod 7 will limit the free rotation of the top support 4. In particular, the support rod 7 can move up and down along the length direction of the screw 1 under the action of the nut 9 and the internal threaded sleeve 6. Therefore, when the support rod 7 moves downward and slides outward in the slide rail 8, the top support 4 rotates downward to a certain angle in the counterclockwise direction under the limiting action of the slide rail 8. When the support rod 7 moves upward and slides inward in the slide rail 8, it will support the top support 4 to rotate upward in the clockwise direction to a certain angle, so that the top support 4 can be restored to the horizontal. The support rod 7 rotates the top support 4 and limits it so that it no longer rotates freely after rotating to a certain angle.

[0033] Before construction, the angle of the top support 4 is fixed by moving the support rod 7 according to the inclination angle of the inclined web and flange of the cast-in-place box beam, so that the inclination angle of the top support 4 is consistent with that of the inclined web and flange. When the box beam formwork is installed, the top support 4 is placed on the top layer of the box beam formwork to support the main beam of the inclined web and flange formwork, and to convert the oblique vertical force into vertical force and guide it to the ground.

[0034] The utility model utilizes industrialized and standardized production components, reduces construction costs and greatly improves the convenience, speed and turnover of installation. The utility model has a simple construction process, and standardized components can effectively reduce material waste, improve construction efficiency and reduce construction costs, and has a wide range of applications.

[0035] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
