Description

Technical Field

[0001] This utility model relates to the field of formwork tie rod technology, and in particular to a water-stop tie rod for the construction of walls with non-uniform cross sections. Background Technology

[0002] Formwork tie rods are rod-shaped components used in formwork construction to fix concrete wall formwork and resist the lateral pressure of newly poured plastic concrete.

[0003] When constructing structural walls using double-sided formwork, three-section water-stop tie rods or through-thread tie rods with welded water-stop plates are often used for reinforcement. However, for the open section of the structural wall in an underpass, due to its trapezoidal structure that is wider at the bottom and narrower at the top, the length of the tie rods on each floor varies, which will lead to the following technical problems:

[0004] 1. If a water-stop screw is used, its conical nut cannot fit into the inclined surface of the formwork, which can easily lead to grout leakage.

[0005] 2. If through-threaded screws are used, the tie rods on the inner wall of the structural wall will be exposed, resulting in poor appearance quality after molding. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a water-stop tie rod for the construction of walls with non-uniform cross sections. It can replace the existing three-section water-stop screw rod and through-thread screw rod, and the contour pad can fit tightly against the outer inclined surface of the formwork, while also ensuring the visual quality of the wall after it is formed.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] This utility model provides a water-stop tie rod for the construction of walls with non-uniform cross-sections, including an inner rod, an outer rod, a water-stop plate, a conical nut, a washer assembly, and at least two washer nuts for fixing the formwork. The formwork includes inclined templates and vertical templates arranged at relative intervals, as well as inclined supports and vertical supports for supporting the inclined templates and vertical templates respectively. The water-stop plate is fixed in the middle of the inner rod. External threads are provided at both ends of the inner rod and the outer rod. The threaded end of the inner rod facing the outer rod and the threaded end of the outer rod facing the inner rod are connected by the conical nut. To form a detachable two-section structure; the pad assembly includes a contour pad for abutting the inclined plane support and a flat pad for abutting the vertical support; when the two-section structure is installed in the formwork, the contour pad is movably sleeved on the inner rod, the flat pad is movably sleeved on the outer rod, the contour pad abuts against the outer inclined plane of the inclined plane support away from the inclined plane template through the cooperation of one of the pad nuts, the flat pad abuts against the outer plane of the vertical support away from the vertical template through the cooperation of the other pad nut, and the conical nut is used to abut against the inner side of the vertical template away from the vertical support.

[0009] Furthermore, the conformal pad includes a base plate, a fixing nut, side pressure plates located on both sides of the base plate, and a fixing rod that can be movably inserted through the two side pressure plates. The base plate is movably sleeved on the inner rod, and the two side pressure plates are movably engaged with the base plate. Through the cooperation of the fixing rod and the fixing nut, the inclined pressing surfaces of the two side pressure plates facing the outer inclined surface abut against the outer inclined surface.

[0010] Furthermore, the substrate has side wings that extend outward toward the side pressure plate on both sides, and each side pressure plate has a relief groove that matches the side wing at one end away from the inclined pressure surface. The two side wings can be movably engaged with their corresponding relief grooves.

[0011] Furthermore, the clearance groove is a U-shaped groove, and the two side walls of the clearance groove respectively form a wing, the side wings respectively abutting against the two corresponding wing.

[0012] Furthermore, each side pressure plate has a through groove at one end near the inclined pressure surface, and the fixing rod is movably inserted through two through grooves; the end of the fixing rod opposite to the fixing nut has a head, and the end of the fixing rod opposite to the head has a threaded portion; the head abuts against one of the side pressure plates; the threaded portion passes through the through groove of the other side pressure plate and is fitted with a pad and a fixing nut, and the fixing nut presses the pad against the corresponding side pressure plate; the side pressure plate moves and swings on the base plate to adjust the angle between the side pressure plate and the base plate, thereby adjusting the angle between the inclined pressure surface and the outer inclined surface.

[0013] Furthermore, the two side plates intersect the substrate.

[0014] Furthermore, when locked, the two side pressure plates form a figure-eight shape.

[0015] Furthermore, when locking, the larger diameter end of the conical nut abuts against the inner side of the vertical template away from the vertical support.

[0016] The technical solution provided by this utility model has the following beneficial effects:

[0017] When the two-section structure is installed on the formwork, the contour pad is pressed against the outer inclined surface of the inclined support away from the inclined template by one of the pad nuts. The flat pad is pressed against the outer plane of the vertical support away from the vertical template by the other pad nut. The conical nut is used to press against the inner side of the vertical template away from the vertical support, so as to ensure that the contour pad can fit tightly against the outer inclined surface of the formwork and also to ensure the visual quality of the wall after it is formed. This can replace the existing three-section water-stop screw and through-thread screw. At the same time, by designing the outer rod and the conical nut as detachable structures, it can be reused repeatedly. Attached Figure Description

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 4 This embodiment provides a water-stop tie rod (hereinafter referred to as water-stop tie rod) for the construction of non-uniform cross-section walls, and uses it in conjunction with the existing formwork 8 to pour concrete to form a non-uniform cross-section wall, namely the wall of the underpass, and the cross-sectional shape of the wall is a right trapezoid with a wider bottom and a narrower top.

[0025] like Figure 3 As shown, the formwork 8 in this embodiment includes a sloping template 83 and a vertical template 81 arranged at a left and right relative distance, as well as a sloping bracket 84 and a vertical bracket 82 for supporting the sloping template 83 and the vertical template 81 respectively.

[0026] After the formwork 8 is erected, the space between the inclined formwork 83 and the vertical formwork 81 is used for pouring concrete, and two supports are used to provide lateral support for the concrete, thereby ensuring that the concrete forms a wall after solidification. The vertical formwork 81 corresponds to the inner side of the underpass, so the requirements for the inner side of the underpass are higher; the inclined formwork 83 corresponds to the outer side of the underpass and can be covered by subsequent backfilling, so the requirements for the outer side of the underpass are lower.

[0027] like Figure 1 As shown, the water-stop tie rod in this embodiment includes an inner rod 1, an outer rod 2, a water-stop plate 3, a conical nut 4, a buckle assembly, a first buckle nut 61, and a second buckle nut 62, for fixing the formwork 8, and as... Figure 3 When the formwork 8 shown is locked, the larger diameter end of the conical nut 4 abuts against the vertical template 81 away from the inner side of the vertical support 82.

[0028] A water-stop plate 3 is fixed in the middle of the inner rod 1. Both ends of the inner rod 1 and the outer rod 2 are provided with external threads. The threaded ends of the inner rod 1 facing the outer rod 2 and the threaded ends of the outer rod 2 facing the inner rod 1 are connected by a conical nut 4 to form a detachable two-section structure. After use, the outer rod 2 and the conical nut 4 can be removed together and reused. The pit formed after removing the conical nut 4 can be filled with concrete.

[0029] The pad assembly of this embodiment includes a contour pad 7 for abutting the inclined support 84 and a flat pad 5 for abutting the vertical support 82. When the two-section structure is installed in the formwork 8, the contour pad 7 is movably sleeved on the inner rod 1, and the flat pad 5 is movably sleeved on the outer rod 2. The contour pad 7 is tightened against the outer inclined surface 841 of the inclined support 84 away from the inclined template 83 by the cooperation of the first pad nut 61. The flat pad 5 is tightened against the outer plane 821 of the vertical support 82 away from the vertical template 81 by the cooperation of the second pad nut 62. The conical nut 4 is used to tighten the inner side of the vertical template 81 away from the vertical support 82. Finally, the entire formwork 8 is tightened by locking the pad nuts, thereby tightening the entire formwork 8 during concrete pouring.

[0030] like Figure 2 As shown, in this embodiment, the contour pad 7 includes a base plate 71, a fixing nut 74, side pressure plates 72 located on both sides of the base plate 71, and a fixing rod 73 that can be movably inserted through the two side pressure plates 72. The base plate 71 is movably sleeved on the inner rod 1. The two side pressure plates 72 are respectively connected to the base plate 71 in a movable engagement. Through the joint cooperation of the fixing rod 73 and the fixing nut 74, the inclined pressing surfaces 721 of the two side pressure plates 72 facing the outer inclined surface 841 abut against the outer inclined surface 841.

[0031] More specifically, the substrate 71 has side wings 711 protruding and extending toward each side pressure plate 72 on both sides. Each side pressure plate 72 has a relief groove that matches the side wing 711 at one end away from the inclined pressure surface 721. The two side wings 711 are movably engaged with their corresponding relief grooves. Specifically, the relief groove is a U-shaped groove, and the two side walls of the relief groove form a retaining wing 722. The side wings 711 abut against the two corresponding retaining wings 722.

[0032] The fixing rod 73 has a head at one end away from the fixing nut 74, and a threaded portion at the other end. Each side pressure plate 72 has a through groove 723 at one end near the inclined pressure surface 721. The fixing rod 73 is movably inserted through two through grooves 723. After the contour pad 7 is assembled, the head of the fixing rod 73 abuts against one of the side pressure plates 72, while the threaded portion of the fixing rod 73 passes through the through groove 723 of the other side pressure plate 72. A fixing nut 74 and a cylindrical or spherical pad 75 are fitted onto the fixing rod 73. The fixing nut 74 presses the pad 75 against the corresponding side pressure plate 72, thus achieving mutual locking. In this way, the pad 75 prevents the side pressure plate 72 from being difficult to rotate before the fixing nut 74 is tightened. Of course, in other embodiments, the pad 75 can be omitted, but this is not conducive to rotating the side pressure plate 72 before the fixing nut 74 is tightened.

[0033] like Figure 4 As shown, during installation, the two side pressure plates 72 move and swing on the base plate 71 to adjust the angle between each side pressure plate 72 and the base plate 71 until the two side pressure plates 72 swing to the appropriate angle. Then, the current position is fixed by the fixing rod 73, thereby adjusting the angle between each inclined pressure surface 721 and the outer inclined surface 841. This ensures that the inclined surface support 84 can adapt to different inclination angles. When the support mold 8 is locked, the two side pressure plates 72 are in a figure-eight shape.

[0034] When the two-section structure is installed on the formwork 8, the contour pad 7 is pressed against the inclined support 84 away from the outer inclined surface 841 of the inclined template 83 by the cooperation of one of the pad nuts. The flat pad 5 is pressed against the vertical support 82 away from the outer plane 821 of the vertical template 81 by the cooperation of the other pad nut. The conical nut 4 is used to press against the inner side of the vertical template 81 away from the vertical support 82, so as to ensure that the contour pad 7 can fit tightly against the outer inclined surface 841 of the formwork 8. It can also ensure the visual quality of the wall after it is formed. This can replace the existing three-section water-stop screw and through screw. At the same time, by designing the outer rod 2 and the conical nut 4 as detachable structures, it can be reused.

[0035] Further preferred, such as Figure 2 As shown, the two side pressure plates 72 intersect the substrate 71 respectively, that is, the distance between the two ends of the two side pressure plates 72 on the side near the inclined bracket 84 is greater than the distance between their two opposite ends, thereby restricting the unfolding direction of each side pressure plate 72.

[0036] Furthermore, when fixing the formwork 8, the base plate 71 is pulled closer to the inclined template 83 on the inner rod 1 by the first washer nut 61. Each side wing 711 drives the corresponding side pressure plate 72 to press against the inclined template 83. Then, by swinging each side pressure plate 72, the fitting angle between each inclined pressure surface 721 and the inclined template 83 meets the installation requirements.

[0037] In this specific embodiment, the inner rod 1 and the outer rod 2 are connected by a conical nut 4. Then, the two-section structure is passed through the support mold 8, with the larger diameter end of the conical nut 4 facing the vertical template 81 and the smaller diameter end facing the inclined template 83. Then, at the two ends of the two-section structure exposed in the support mold 8, a flat gasket 5, a contoured gasket 7, and a matching buckle nut are nested respectively. The flat gasket 5 is installed on the right side of the vertical support 82, and the contoured gasket 7 is installed on the left side of the inclined support 84. Then, the flat gasket 5 is made to fit the vertical support 82 by locking the second buckle nut 62.

[0038] At the same time, the first washer nut 61 drives the base plate 71 to close the distance with the inclined template 83. The base plate 71 drives the side pressure plate 72 to approach the inclined bracket 84. Then, by swinging the side pressure plate 72, the contact angle between the inclined pressure surface 721 and the inclined bracket 84 is found. After the side pressure plate 72 swings to a suitable angle, the distance between the two side pressure plates 72 is brought closer by tightening the fixing nut 74 on the fixing rod 73. This makes the inclined pressure surface 721 press against the inclined bracket 84, and the clamping wing 722 presses against the base plate 71 from the side to fix the installation position of the side pressure plate 72 at this time. Then, the second washer nut 62 is locked, so that the base plate 71 presses the side pressure plate 72 and the side wing 711 presses against the side pressure plate 72. This ensures that the inclined pressure surface 721 presses against the inclined bracket 84, and after locking, the position of the inclined template 83 and the inclined bracket 84 is fixed, and the inclined template 83 and the inclined bracket 84 are supported according to their inclination.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
