Description

Technical Field

[0001] The utility model belongs to the field of support jacking structures, and in particular relates to a top plate support jacking with an adaptive slope. 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 a rotatable and height-adjustable top support on the pole, and installs horizontal or vertical main ribs on the top support. Secondary ribs perpendicular to the main ribs are placed on the main ribs at a certain spacing, and the top plate bottom template is placed on the top of the secondary ribs, and then concrete is poured on the template.

[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. Utility Model Content

[0004] In order to overcome the problems existing in the background technology, the utility model provides a top plate bracket with an adaptive slope. By arranging an adaptive angle adjustment part between the bracket body and the top plate, the upper top plate can automatically adjust the angle as the slope of the top plate changes, and automatically adapt to the change of 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.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0008] Preferably, the upright pole is connected to the support plate in an adjustable height.

[0009] Preferably, the upper support plate is a grooved plate with the groove opening facing upward.

[0011] Preferably, the supporting body comprises a vertical pole and a support plate arranged at the top end of the vertical pole; and the adaptive angle adjustment member is arranged above the support plate.

DETAILED DESCRIPTION

[0020] 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.

[0021] 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.

[0022] 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.

[0023] like Figure 2-4 As shown, the top support of the self-adaptive slope top plate bracket includes a top support body and an self-adaptive angle adjustment member. The top support body is a top support structure currently in use, including a vertical pole 4 and a support plate 5 arranged on the top of the vertical pole 4, wherein the support plate 5 is connected to the vertical pole 4 in an adjustable height, and the adjustable height is an existing connection structure. As one of the adjustable height connection methods, the vertical pole 4 can be made of a telescopic rod; or a bolt rod is arranged on the lower end surface of the support plate 5, and a threaded hole is opened on the upper end surface of the vertical pole 4, so that the support plate 5 is connected to the vertical pole threaded with an adjustable height. The support plate 5 of the existing structure is a grooved plate. When in use, the main rib 13 is supported by the support plate 5, and the grooved structure of the support plate 5 can confine the main rib 13 in the groove, but the contact between the main rib 13 and the secondary rib 12 of the structure is a line contact (as shown in the attached figure). Figure 1 ), the support is unstable and it is difficult to meet the safety support requirements, resulting in poor construction quality.

[0024] The utility model adds an adaptive angle adjustment member on the basis of the existing top support body structure. By adding the adaptive angle adjustment member, it can automatically adapt to the top slope of any angle, and at the same time can increase the contact area between the main rib 13 and the secondary rib 12, thereby improving the safety of the top plate structure and the construction quality of the top plate.

[0025] The adaptive angle adjustment member includes a lower support plate 1, a hinge 2 and an upper support plate 3. The upper support plate 3 and the lower support plate 1 are hinged by the hinge 2 to achieve angle adjustment between the lower support plate 1 and the upper support plate 3. The details are as follows:

[0026] The hinge 2 includes a shaft sleeve 21 and a rotating shaft rotatably connected to the shaft sleeve 21. The rotating shaft is an integrated structure, including a middle shaft body 22 and two end shaft bodies 23. The outer diameter of the middle shaft body 22 is larger than the two end shaft bodies 23 (such as the attached Figure 3), the sleeve 21 is sleeved on the shaft bodies 23 at both ends, and the sleeve 21 is rotatably connected to the shaft bodies 23 at both ends. The middle shaft body 23 is fixedly connected to the upper support plate 3, and the sleeve 21 is fixedly connected to the lower support plate 1. The sleeve 21 and the rotating shaft can rotate freely, thereby driving the free adjustment of the angle between the upper support plate 3 and the lower support plate 1. The middle shaft body 22 has the same outer diameter as the sleeve 21, and the middle shaft body 22 is welded to the upper support plate 3, and the sleeve is welded to the lower support plate 1. There should be a certain gap between the upper support plate 3 and the sleeve 21, and between the lower support plate 1 and the middle shaft body 22 to reduce the friction generated during rotation. Practice has proved that the welding connection relationship can meet the gap required for rotation, which is conducive to reducing friction. Taking the middle shaft body 22 and the upper support plate 3 as an example, after welding, the weld makes the upper support plate 3 slightly higher than the middle shaft body 22, and then there is a slight gap between the upper support plate 3 and the sleeve 21, which can prevent excessive friction between the upper support plate 3 and the sleeve 21 when rotating. In addition, other components can be set (for example, adding a welding pad at the welding surface of the middle shaft body 22 and the upper support plate 3) to make a certain gap between the upper support plate 3 and the sleeve 21 to avoid or reduce friction during rotation.

[0027] The upper support plate 3, the lower support plate 1 and the support plate 5 are all groove-shaped plates. The grooves of the lower support plate 1 and the support plate 5 are opposite, and the groove bottoms are in contact with each other. In this way, there is a mutual limiting effect between the two groove-shaped plates to prevent the lower support plate 1 and the support plate 5 from shifting during the rotation process. The groove directions of the upper support plate 3 and the lower support plate 1 are perpendicular to each other, and the hinges 2 are respectively welded to the back sides (the reverse side of the groove) of the upper support plate 3 and the lower support plate 1. After welding, the groove of the upper support plate 3 limits the main rib 13 to prevent the main rib 13 from falling. In order to ensure that the main rib 13 contacts and supports the secondary rib 12, the groove height of the upper support plate 3 is smaller than the outer dimensions of the main rib 13.

[0028] According to the structure of the utility model, after the top supporting body is fixed, the upper top plate 3 and the lower top plate 1 can be automatically adjusted at any time when the slope of the top plate changes, automatically adapt to the change of the slope of the top plate, increase the contact area between the main ribs 12 and the secondary ribs 12, improve the safety of the top plate structure, and improve the construction quality of the top plate.

[0029] 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.
