Description

Technical Field

[0001] The present application relates to the field of formwork engineering accessory materials in building construction, and specifically to a sleeve screw structure. Background Art

[0002] In the construction of concrete walls, it is necessary to first build a wall casting formwork, and then fix the outside of the casting formwork through structures such as keels and back ribs to ensure the final concrete pouring effect. In order to ensure that the required spacing can be maintained between the parallel walls or beam surfaces, it is also necessary to set an internal support and a plastic sleeve with a through-screw hole between the wall formwork or beam side formwork on both sides. For example, most aluminum formworks in the existing technology use a single conical tube-type concealed sleeve. Our company has applied for a patent for a concealed sleeve structure called "A wall-penetrating concealed pipe tensioning screw assembly with turnover and adjustable size (application number 202020164614.4)", but the mountain-shaped card is more suitable for traditional round tube support structures, but cannot be adapted to the square tube support structure developed by our company. Therefore, a product that can better match the square tube structure is needed. Utility Model Content

[0003] In response to the shortcomings of the existing technology, this application provides a sleeve screw structure, which optimizes the structure of the product, enables the product to better cooperate with the square tube support structure, further improves the product's use effect, and ensures the stability of the product during use.

[0004] A sleeve screw structure comprises a threaded rod, a sleeve sleeved on the threaded rod, and two clamps sleeved on the threaded rod and located on both sides of the sleeve; any one of the clamps is fixed to the threaded rod as a whole.

[0005] Preferably, the two clamps are symmetrically arranged on the threaded rod.

[0006] Furthermore, the clamping head is composed of two parallel side plates, a top plate spanning the upper ends of the two side plates, a bottom plate spanning the lower ends of the two side plates, a U-shaped limit frame spanning the lower ends of the two side plates, a nut head arranged on the side surface of the top plate, an upper hole arranged on the top plate, and a lower hole arranged on the bottom plate.

[0007] Preferably, the nut head is provided with an internal threaded hole that passes through the nut head and matches the threaded rod.

[0008] Preferably, the nut head is fixed to the top plate by welding.

[0009] Preferably, the diameters of the upper hole and the lower hole are larger than the outer diameter of the threaded rod.

[0010] Preferably, the central axis of the internal threaded hole of the nut head, the central axis of the upper hole and the central axis of the lower hole are coaxial.

[0011] Preferably, the diameter of the upper hole is smaller than the outer diameter of the nut head.

[0012] Preferably, there are two U-shaped limit frames, which are respectively arranged on the left and right sides of the bottom plate; the two ends of the U-shaped limit frame are respectively fixed on the two side plates and are fixed as one body with the side plates.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] The utility model optimizes the structure of the product, so that the product can better cooperate with the square tube support structure, further improves the use effect of the product, and ensures the stability of the product during use.

[0028] Example 1

[0029] like Figure 1 As shown, a sleeve screw structure includes a threaded rod 200, a sleeve 300 sleeved on the threaded rod 200, and two clamps 100 sleeved on the threaded rod 200 and located on both sides of the sleeve 300; any one of the clamps 100 is fixedly integrated with the threaded rod 200.

[0030] The two clamping heads 100 are symmetrically arranged on the threaded rod 200 .

[0031] like Figure 2 、 3 As shown, the clamp 100 consists of two parallel side plates 101, a top plate 102 spanning the upper ends of the two side plates 101, a bottom plate 103 spanning the lower ends of the two side plates 101, a U-shaped limit frame 105 spanning the lower ends of the two side plates 101, a nut head 104 arranged on the upper side of the top plate 102, an upper hole 107 arranged on the top plate 102, and a lower hole 106 arranged on the bottom plate 103.

[0032] The nut head 104 is provided with an internal threaded hole that passes through the nut head 104 and matches the threaded rod 200 .

[0033] The nut head 104 is fixed to the top plate 102 by welding.

[0034] The diameters of the upper hole 107 and the lower hole 106 are larger than the outer diameter of the threaded rod 200 .

[0035] The central axis of the internal threaded hole of the nut head 104 , the central axis of the upper hole 107 and the central axis of the lower hole 106 are coaxial.

[0036] The diameter of the upper hole 107 is smaller than the outer diameter of the nut head 104 .

[0037] During setting, any nut head is screwed into the threaded rod and then the nut head and the threaded rod are fixed together by welding, so that the product does not need to be fixed in two directions when in use, which greatly reduces the difficulty of using the product and improves the efficiency of product use.

[0038] There are two U-shaped limit frames 105 , which are respectively arranged on the left and right sides of the bottom plate 103 ; the two ends of the U-shaped limit frames 105 are respectively fixed on the two side plates 101 and are integrally fixed with the side plates 101 .

[0039] When in use, the U-shaped limit frame can be clamped on both sides of the square tube with the threaded rod function, and the bottom plate and the U-shaped limit frame can effectively fit on the side wall of the square tube to limit it, thereby avoiding displacement of the square tube during setting and use.

[0040] In this application, the U-shaped limit frame adopts a U-shaped structure rather than an integral plate structure, and there is a hollow structure between the two side panels, which can not only ensure that the product has a certain strength, but also effectively reduce the overall weight of the product. It not only reduces the production and use costs of the product, but also reduces the overall weight of the wall column system after it is completed.

[0041] Example 2

[0042] like Figure 4 As shown, the threaded rod in this embodiment is threaded only at one end, the top plate and the nut head are removed from the clamp at the end without the thread, and the bottom plate is fixed to the threaded rod by welding.

[0043] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0044] In addition, the above-mentioned specific embodiments are merely illustrative. Those skilled in the art may devise various solutions based on the disclosure of this utility model, and such solutions fall within the scope of disclosure and the scope of protection of this utility model. Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
