Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building construction, and in particular to a clamp installation device. Background Technology
[0002] In the construction of tie beams and cap beams in bridge engineering, clamps are key components providing support for the supports, and their installation quality directly affects the stability and safety of the entire construction structure. Invention patent CN119531504A discloses an enlarged head pile load-bearing clamp and its construction method. The specific steps of the construction method are as follows: Customize a first clamp assembly, a second clamp assembly, and a reinforcement mechanism according to the dimensions of the column; install the outer clamp, inner clamp, and reinforcement cover plate sequentially onto the column, and install the second reinforcement seat onto the upper part of the reinforcement cover plate; install the support square tube and the half-clamp ring onto the column, aligning and fixing the support base plate with the reinforcement cover plate; fix the reinforcement support strip to the half-clamp ring and the reinforcement cover plate respectively; inject cement grout into the interior of the support square tube, and inject cement grout into the interior of the outer clamp through the grouting pipe.
[0003] As can be seen, the existing clamp installation relies on the experience of installers for positioning. Due to the limited accuracy of manual positioning, clamp installation positions are prone to deviation, leading to the following problems: During tie beam construction in columns, inaccurate clamp positioning may cause uneven stress on the tie beam support, affecting the integrity of the tie beam structure; and during cap beam construction, inaccurate clamp positioning can cause deformation of the cap beam formwork support, thus affecting the quality of cap beam pouring, both posing serious safety hazards to bridge engineering. Therefore, traditional clamp installation methods can no longer meet the stringent requirements of modern bridge engineering for construction convenience and efficiency. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] This utility model provides a clamp installation device, the specific structure of which is as follows:
[0025] like Figures 1 to 3As shown, the clamp installation device is used to restrict the clamp 3 to be installed at a designated position on the pier 5. It includes a limiting ring 1 sleeved on the outer wall of the pier 5. The limiting ring 1 is positioned at the designated position and abuts against the clamp 3. When installing the clamp 3, the limiting ring 1 is first sleeved on the designated position on the pier 5, and then the clamp 3 is sleeved on the pier 5 and abuts against the limiting ring 1. This achieves the effect of accurately determining the installation position of the clamp 3 and improves the speed and accuracy of clamp 3 installation.
[0026] The limiting ring 1 can abut its top end against the bottom end of the clamp 3, or its bottom end against the top end of the clamp 3, both of which can meet the requirement of accurately positioning the clamp 3 during installation. Preferably, the top end of the limiting ring 1 abuts against the bottom end of the clamp 3. During the installation of the clamp 3, the limiting ring 1 can provide support for the clamp 3, making it easier for the installer to rotate the clamp 3 to align it with the corresponding mounting holes of the clamp 3 and the pier column 5.
[0027] like Figure 1 and Figure 2 As shown, the clamp installation device also includes at least one positioning part 2 disposed on the limiting ring 1. The positioning part 2 abuts against the outer wall of the clamp 3 to limit the clamp 3 from displacement in its radial direction during installation. In a specific embodiment, the top end of the limiting ring 1 abuts against the bottom end of the clamp 3, and the positioning part 2 abuts against the outer wall of the clamp 3. The two work together to ensure the stability of the clamp 3 during installation. Furthermore, to ensure effective fixing of the clamp 3 by the positioning part 2, the positioning part 2 is welded to the limiting ring 1, and its height exceeds the limiting ring 1 by at least 5 cm.
[0028] To facilitate the installation and removal of the limit ring 1, such as Figure 2 As shown, the limiting ring 1 includes at least two limiting parts 11, and adjacent limiting parts 11 are detachably connected. Further, adjacent limiting parts 11 are interconnected by a connecting structure. The connecting structure includes two connecting holes 41 respectively provided on the two limiting parts 11, and fasteners 42 passing through the two connecting holes 41 in sequence. The fasteners 42 can be pins or bolts.
[0029] To allow adjustment of the size of the limiting ring 1 and ensure its secure placement at the designated position on the pier 5 without detachment, the connection structure further includes a limiting member 43 for restricting the axial displacement of the fastener 42 along the connecting hole 41. The fastener 42 is preferably a bolt, and the limiting member 43 is preferably a nut. The threaded part of the fastener 42 passes through both connecting holes 41 and is threadedly connected to the limiting member 43. Furthermore, the connection structure also includes a gasket 44 for dispersing the pressure of the limiting member 43, the gasket 44 being disposed between the limiting member 43 and the limiting portion 11.
[0030] like Figure 2As shown, to ensure that the two adjacent limiting parts 11 can withstand force without deformation when connected, the limiting part 11 includes a limiting body 111 and connecting members 112 with the aforementioned connecting holes 41 at both ends of the limiting body 111. The connecting members 112 are welded to the limiting body 111 and are also connected to the limiting body 111 through at least one reinforcing rib 113. The reinforcing rib 113 is preferably triangular in shape, with one right-angled side connected to the connecting member 112 and the other right-angled side connected to the limiting body 111, which can significantly enhance the structural stability of the entire clamp installation device. In a specific embodiment, the connecting member 112 is a 10cm long and 1cm thick steel plate, the connecting hole 41 is located at the center of the connecting member 112, and the two triangular reinforcing ribs 113 are respectively provided on both sides of the connecting member 112, which can provide stable support for the fixing of the connecting member 112 to the limiting body 111.
[0031] In some embodiments, the inner wall of the limiting ring 1 is provided with an elastic part for increasing the friction between the limiting ring 1 and the pier 5. The limiting ring 1 is preferably a steel ring, and the elastic part is preferably a rubber gasket. The presence of the rubber gasket can increase the friction between the limiting ring 1 and the pier 5 and protect the outer surface of the pier 5 from being scratched by the limiting ring 1.
