Description

Technical Field

[0001] The utility model belongs to the field of bracket jacking, and specifically relates to a bracket jacking which can adapt to the slopes of a top plate in all directions. Background Art

[0002] In the construction industry, all kinds of buildings are basically based on concrete structures. Almost all housing construction, roads, railways, airports and other fields involve cast-in-place concrete structures using the support method. The top plates, middle plates or roofs (hereinafter collectively referred to as top plates) of these concrete structures are mostly non-horizontal. In the actual construction process, the top plate formwork support system usually first installs support poles with certain spacing and rows, and rotatable and height-adjustable top supports on the poles. The top supports are installed with horizontal or vertical main ribs, and secondary ribs perpendicular to the main ribs are placed on the main ribs at a certain spacing. The top plate bottom formwork is placed on the top of the secondary ribs, and then concrete is poured on the formwork (such as the attached Figure 1 ).

[0003] When encountering an inclined roof, no matter the main rib is double steel bar, I-beam or other components, it is impossible to simultaneously meet ① the roof slope and ② the complete fit between the secondary rib and the main rib. The expected surface fit of the bracket design can only be converted into line contact (such as the attached Figure 1 ), this method weakens the supporting capacity of the main ribs on the inclined top surface and cannot guarantee the construction quality and safety.

[0004] Moreover, the top supports of the existing structures can only adapt to the slope in one direction. During the construction process, the top supports are usually constructed first and then the top plate is installed. In order to meet the slope and direction requirements of the top plate, the installation direction of the top supports needs to be strictly controlled, which places high demands on the construction of the top supports. Utility Model Content

[0005] In order to overcome the problems existing in the background technology, the utility model provides a bracket support that can adapt to the slope of the top plate in all directions. By arranging a rotatably connected spherical groove body and a spherical support between the upper support plate and the lower connecting piece, the upper support plate can be rotated at any angle and inclination through the spherical groove body and the spherical support. When the slope of the top plate changes, the upper support plate can automatically adjust the inclination as the slope of the top plate changes, and automatically adapt to the change in the slope of the top plate. While meeting the slope requirements of the top plate, the contact area between the main ribs and the secondary ribs is increased, thereby improving the safety of the top plate structure and the construction quality of the top plate. In addition, the upper support plate can also meet the requirements of any changes in the slope direction of the top plate, thereby reducing the requirements for the installation accuracy of the bracket during construction.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] The bracket support that can adapt to the slope of the top plate in all directions includes an upper support plate, a spherical groove body, a spherical support and a lower connecting piece; the spherical groove body is fixed to the lower end surface of the upper support plate with the notch facing downward; the spherical support is fixed to the upper end surface of the lower connecting piece; the spherical support is inserted into the spherical groove body and is rotatably connected to the spherical groove body.

[0008] Preferably, a snap ring is installed on the lower end surface of the spherical groove body to prevent the spherical support from falling off from the spherical groove body.

[0009] Preferably, the snap ring is formed by two semicircular snap rings.

[0010] Preferably, the clamping ring is bolted to the spherical groove body.

[0011] Preferably, the lower connecting member is a screw.

[0012] Preferably, a connecting short rod is provided between the screw rod and the spherical support.

[0013] Preferably, the lower connecting member is a bottom supporting plate, and the bottom supporting plate is a grooved plate.

[0015] Beneficial effects of the utility model:

[0016] The utility model provides a rotatably connected spherical groove body and a spherical support between the upper support plate and the lower connecting piece, so that the upper support plate can be rotated at any angle and inclination through the spherical groove body and the spherical support.

[0023] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0024] In the description of the present invention, unless otherwise specified, the terms "upper", "lower", etc., indicating the orientation or state relationship are based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention will be understood according to specific circumstances. Example 1

[0026] like Figure 2 and 3 As shown, the support bracket capable of self-adapting to the slope of the top plate in all directions comprises an upper support plate 1, a spherical groove body 2, a spherical support 3 and a lower connecting member 4. The lower connecting member 4 is a screw.

[0027] The notch of the spherical groove body 2 is fixed to the lower end surface of the upper support plate 1 with the notch facing downward, the spherical support 3 is fixed to the upper end surface of the lower connecting member 4, and the spherical support 3 is inserted into the spherical groove body 2 and rotatably connected to the spherical groove body 2. A connecting short rod 6 is provided between the screw and the spherical support 3, and the connecting short rod 6 can increase the rotation space of the upper support plate 1 and increase the adjustable range of the inclination of the upper support plate 1.

[0028] By providing a rotatably connected spherical groove body 2 and a spherical support 3 between the upper support plate 1 and the screw rod, the upper support plate 1 can be rotated at any angle and inclination through the spherical groove body 2 and the spherical support 3. When the slope of the top plate changes, the upper support plate 1 can automatically adjust the inclination as the slope of the top plate changes, automatically adapt to the change in the slope of the top plate, and while meeting the slope requirements of the top plate, increase the contact area between the main ribs and the secondary ribs, thereby improving the safety of the top plate structure and the construction quality of the top plate. In addition, the upper support plate 1 can also meet the requirements of any changes in the slope direction of the top plate, thereby reducing the requirements for the accuracy of the top support installation during construction.

[0029] In order to prevent the spherical support 3 from falling off from the spherical groove body 2, a snap ring 5 is installed on the lower end surface of the spherical groove body 2, and the inner side surface of the snap ring is an arc surface that fits the spherical support 3. The inner diameter of the lower end of the snap ring 5 is smaller than the maximum diameter of the spherical support 3. In order to facilitate installation, the snap ring 5 is surrounded by two semicircular snap rings, and a through bolt hole is opened on the snap ring 5. The lower end surface of the spherical groove body 2 is opened with a bolt hole corresponding to the snap ring 5, and the snap ring 5 is bolted to the spherical groove body 2.

[0030] An example of the method of use of the utility model is as follows: the existing top support 15 is removed, an internal thread matching the screw rod is provided on the upper end surface of the column 16, the screw rod is inserted into the column 16, and the screw rod is connected with the column 16 in an adjustable height. The screw rod is connected with the column 16 and the height is adjusted to meet the height requirements of the top plate. When constructing the top plate, the rotating connection structure of the spherical support 3 and the spherical groove body 2 can enable the upper support plate 1 to automatically adjust the angle as the slope and direction of the top plate change.

[0031] The upper supporting plate 1 is a groove-shaped plate, which has the same structure as the existing top supporting plate 15 , and can limit the main ribs 13 to prevent the main ribs 13 from sliding off the upper supporting plate 1 . Example 2

[0032] like Figure 4 and 5 As shown, the difference between this embodiment and embodiment 1 is that the lower connecting member 4 of the utility model is a bottom support plate, and the remaining structures are the same as those of embodiment 1. This embodiment mainly describes the structure and use method of the bottom support plate.

[0033] The bottom support plate is a grooved plate, and a connecting short rod 6 is welded between the bottom support plate and the spherical support 3. The upper support plate 1 of this embodiment can automatically adjust the angle as the slope and direction of the top plate change, just like the embodiment 1.

[0034] An example of the method of using the utility model is as follows: retain the existing top support 15 (the existing top support 15 is also a groove-shaped plate), the grooves of the bottom support plate and the existing top support 15 are opposite, and the bottom of the grooves fit each other, so that the two groove-shaped plates are mutually limited to prevent the bottom support plate and the existing top support 15 from shifting. During construction, first complete the construction of the column 16 and the existing top support 15, then place the groove of the bottom support plate relative to the existing top support 15, the overall structure of the utility model is placed on the existing top support 15, and then start construction. When constructing the top plate, the rotating connection structure of the spherical support 3 and the spherical groove body 2 can enable the upper support plate 1 to automatically adjust the angle and inclination as the slope and direction of the top plate change.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
