Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a five-section tension screw rod. Background Art

[0002] Tie rods, also known as tie bolts or tie rods, are commonly used in construction projects to fix and support concrete formwork. It usually consists of a screw and a nut, with both ends fixed to the building formwork. By tightening the nut to generate a preload, the formwork remains fixed and tightly connected to prevent displacement and leakage of the formwork or expansion and deformation during concrete pouring. Tie rods play an important role in construction, especially when pouring large concrete structures, such as bridges and high-rise concrete structures. They ensure the stability of the formwork, thereby ensuring that the size and shape of the concrete structure meet the design requirements. After the concrete hardens, the tie rods can be taken out and reused, or the exposed concrete portion can be cut off, while the screw head usually remains inside the concrete.

[0003] Ordinary tie screws have their limitations in construction. For example, the tightening force of ordinary tie screws may be uneven, resulting in poor tightening of the formwork, which may affect the accuracy of the formwork and the quality of the concrete structure; there is also the problem of inconvenient disassembly. Therefore, it is necessary to propose a new type of tie screw to improve the tightening effect of the formwork, improve construction efficiency, facilitate adjustment of the screw length and disassembly, low maintenance cost, and wide applicability. Utility Model Content

The screw rod can be customized in multiple sets of different lengths to be suitable for use environments with different spacings.

[0007] The intermediate mother-and-child threaded rod comprises a short mother-and-child threaded rod, one end of which is provided with a first threaded hole which is threadedly connected to and cooperates with the screw rod, and a frustum rubber plug and a circular rubber plug are tightly sleeved on the short mother-and-child threaded rod in sequence.

[0008] The end mother-and-child threaded rod comprises a long mother-and-child threaded rod, one end of which is provided with a second threaded hole threadedly connected to and matched with the short mother-and-child threaded rod, and the other end outer wall of the long mother-and-child threaded rod is provided with a threaded fixing nut and an arc-shaped clip locator that is inserted and connected.

[0009] Furthermore, the end with a smaller diameter of the frustum rubber plug faces one side of the screw rod, and the end with a larger diameter faces one side of the end threaded rod.

[0010] Furthermore, the annular rubber plug is tightly attached to the end of the frustum rubber plug with a larger diameter.

[0011] Furthermore, the arc-shaped inner opening of the arc-shaped buckle locator faces one side of the middle mother-and-child threaded rod, and the fixing nut is tightly attached to one side of the arc-shaped outer edge of the arc-shaped buckle locator.

[0012] Furthermore, a short threaded rod outer edge protrusion is provided on the outer edge of the port of the short-type mother-and-child threaded rod close to the first threaded hole, and the short threaded rod outer edge protrusion abuts against the outer port of the conical rubber plug.

DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, this embodiment discloses a five-section tension screw rod, including a screw rod 3, wherein the threads at both ends of the screw rod 3 are connected with an intermediate mother-and-child threaded rod 2, and the outer end of the intermediate mother-and-child threaded rod 2 is connected with an end mother-and-child threaded rod 1 by threads. The screw rod 3 can be customized in multiple sets of different lengths to suit different spacing usage environments.

[0027] like Figure 3 and Figure 4 As shown, the middle mother-and-child threaded rod 2 includes a short mother-and-child threaded rod 203, and a thread that cooperates with the end mother-and-child threaded rod 1 is arranged on the outer wall of one end of the short mother-and-child threaded rod 203, and a first threaded hole 206 that cooperates with the screw rod 3 is arranged at the other end of the short mother-and-child threaded rod 203. A conical rubber plug 202 and a circular rubber plug 201 are tightly sleeved on the short mother-and-child threaded rod 203 in sequence.

[0028] A short threaded rod outer edge protrusion 205 is provided on the outer edge of the port of the short-type mother-and-child threaded rod 203 close to the first threaded hole 206, and the short threaded rod outer edge protrusion 205 abuts against the outer port of the frustum rubber plug 202. A short threaded rod boss 204 is provided on the outer wall of the short-type mother-and-child threaded rod 203, close to the short threaded rod outer edge protrusion 205. The short threaded rod boss 204 is inserted into the cavity of the frustum rubber plug 202, thereby playing an auxiliary tightening role for the frustum rubber plug 202.

[0029] The end of the frustum rubber plug 202 with a smaller diameter faces the screw rod 3 , and the end with a larger diameter faces the end threaded rod 1 .

[0030] The annular rubber plug 201 is tightly attached to the end of the frustum rubber plug 202 with a larger diameter.

[0031] like Figure 5 and Figure 6 As shown, the end mother-and-child threaded rod 1 includes a long mother-and-child threaded rod 103, one end of which is provided with a second threaded hole 106 threadedly connected to the short mother-and-child threaded rod 203, and the other end of the long mother-and-child threaded rod 103 is provided with a threaded fixing nut 101 and an arc-shaped clip locator 102 that is inserted and connected on the outer wall.

[0032] A long threaded rod outer edge protrusion 105 is provided on the outer edge of the port of the long mother-and-child threaded rod 103 close to the second threaded hole 106, and a long threaded rod boss 104 is provided on the outer wall of the long mother-and-child threaded rod 103 close to the long threaded rod outer edge protrusion 105. The long threaded rod boss 104 can assist the screwing action and facilitate disassembly, and the long threaded rod outer edge protrusion 105 can facilitate alignment with the docking middle mother-and-child threaded rod 2 during assembly.

[0033] The arc-shaped inner opening of the arc-shaped buckle locator 102 faces one side of the middle threaded rod 2 , and the fixing nut 101 is tightly attached to one side of the arc-shaped outer edge of the arc-shaped buckle locator 102 .

[0034] The action process of the utility model is as follows:

[0035] like Figure 7 As shown, in this embodiment, the implementation method of the five-section tie screw is as follows: first, the annular rubber plug 201 is sleeved on the end with a larger diameter of the frustum rubber plug 202, and the entire assembly is sleeved on the short-type threaded rod 203. Then, the two sections of the short-type threaded rod 203 are respectively threadedly connected to the ends of the screw 3 on both sides. This part of the device is located between the two templates 4, and the main function of the annular rubber plug 201 is to prevent concrete from seeping out from the edge of the hole in the template 4 when pouring concrete.

[0036] Afterwards, the long mother-and-child threaded rod 103 is passed through the reserved hole of the template 4 and connected to the short mother-and-child threaded rod 203 through a threaded interface. Then, the arc-shaped buckle locator 102 is connected in series and on the long mother-and-child threaded rod 103. By rotating the fixing nut 101, the arc-shaped buckle locator 102 can be accurately fastened to the position on the long mother-and-child threaded rod 103. The long mother-and-child threaded rod 103 and the fixing nut 101 are located on the outside of the template 4, and work together with the internal annular rubber plug 201 to firmly clamp the template 4 therebetween, ensuring that the template 4 remains fixed during concrete pouring, and providing the necessary pulling force to prevent the template 4 from expanding or deforming due to the pressure of the concrete, providing a stable and uniform support structure for concrete pouring. When disassembling, the end mother-and-child threaded rod 1 and the middle mother-and-child threaded rod 2 are disassembled in turn.

[0037] The utility model has a simple structure and ingenious design and has the following advantages:

[0038] (1) Easy disassembly: The entire device can be loosened or tightened at will. After the concrete hardens, the end threaded rod 1 and the middle threaded rod 2 can be easily disassembled without additional destruction.

[0039] (2) High construction efficiency: The quick disassembly and assembly characteristics of the five-section tension screw can significantly reduce the time for removing the formwork 4 and recovering the screw, thereby improving the overall construction efficiency.

[0040] (3) Low maintenance cost: Since the utility model can be reused, it reduces material waste and also reduces long-term maintenance costs.

[0041] (4) Improving concrete quality: By evenly applying tension, the five-section tension screw helps to improve the stability of the formwork, thereby ensuring the flatness and accuracy of the concrete structure.

[0042] (5) Improved safety: The quick disassembly and assembly of the screw reduces the time workers spend working at height and reduces safety risks during the construction process.

[0043] (6) Wide applicability: The five-section tension screw is suitable for a variety of construction scenarios, especially in large concrete structures and projects with high precision requirements.

[0044] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
