Description

Technical Field

[0001] The utility model relates to the technical field of tenon-shaped anti-falling beam embedded hole positioning, and specifically relates to a positioning tool for anti-falling beam embedded holes. Background Technique

[0002] At present, during bridge construction, tenon-shaped anti-falling beams are used for connection, and it is designed to be fixed at one end on the pier top and at the other end on the beam bottom. The pier top part is fixed by the form of pouring support grout after reserving holes. Currently, the positioning operation of the reserved holes in the pier top part is mainly to fix a simple support on the pier top template to erect the reserved hole steel barrel.

[0003] However, when the existing positioning tooling is used, due to the fixed size of the hole and the inability to adjust according to the situation, there will be a phenomenon that the hole is larger than the reserved hole steel barrel. The reserved hole steel barrel is prone to tilt in the hole, resulting in the deviation of the position and angle of the reserved hole, inaccurate positioning, and inability to meet the high-precision requirements of construction positioning.

[0004] The above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is the closest prior art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above deficiencies and provide a positioning tool for anti-falling beam embedded holes.

[0011] Further, the adjusting component further includes two support plates fixed to the side parts of the corresponding limiting blocks two on the screw rods.

[0012] Further, the adjacent ends of the first C-shaped frame and the second C-shaped frame are not connected.

[0013] Further, L-shaped connecting plates are fixed to the bottom ends of the first C-shaped frame and the second C-shaped frame.

[0014] Further, a sliding groove for cooperating with the movement of the L-shaped connecting plate is arranged on the pier top formwork.

[0026] like Figure 1-4 As shown, the utility model provides a positioning tool for embedded holes of anti-fall beams, including a pier top template for casting and forming a pier top, and the pier top template is provided with a mold frame 1 and a mold frame 2 for positioning embedded holes of anti-fall beams on the pier top, and also includes:

[0027] The limiting component 3 is set between the profile frame 1 and the profile frame 2, and two are in a group, which is used to clamp and limit the steel drum with a reserved hole inserted when pouring on the pier top;

[0028] The adjustment component 4 is arranged on the side of the profile frame 2 and is used in conjunction with the limit component 3 to adjust the adjacent spacing between the limit components 3 assembled between the profile frame 1 and the profile frame 2. This design, through the use of the profile frame 1 and the profile frame 2 on the pier top formwork, wherein the limit components 3 assembled between the profile frame 1 and the profile frame 2 are grouped in pairs, it is possible to clamp and fix the steel drums for the reserved holes placed on the pier top during pouring in the horizontal and vertical directions, thereby realizing the reservation of the embedded holes for the anti-fall beams;

[0029] Also, by using the adjustment component 4 in conjunction with the limit component 3 on the side of the profile frame 2, not only can the distance between two limit components 3 in a group be adjusted to achieve the clamping and fixation of steel drums with reserved holes of various specifications and sizes, but also the distance between two adjacent groups of limit components 3 can be adjusted. In addition, the L-shaped connecting plate 5 with the damping connection on the slide 6 can be used to accurately locate the embedded holes for preventing falling beams between the pier top templates, and the use effect is good.

[0030] In one embodiment, the limiting assembly 3 includes a limiting block 1 31 and a limiting block 2 32 that are slidably connected on the shaped frame 1 and the shaped frame 2 2, and a spring 33 that is provided on the adjacent end surfaces of the limiting block 1 31 and the limiting block 2 32. With this design, by using the limiting block 1 31 and the limiting block 2 32 that are slidably connected to the support rods on the shaped frame 1 and the shaped frame 2 2, and the spring 33 that is welded and fixed between the limiting block 1 31 and the limiting block 2 32, after the pre-hole steel barrel is installed between the two limiting assemblies 3, the horizontal and lateral expansion or contraction space will be fed back in real time under the elastic support of the spring 33, thereby achieving the horizontal and lateral fixing effect of the pre-hole steel barrel.

[0031] Preferably, a shaped plate 34 is slidably provided on one side of the spring 33 and on the side of the limit block 1 31 and the limit block 2 32. With this design, the shaped plate 34 is slidably connected to the surface of the limit block 1 31 and the limit block 2 32, and the inner groove surface of the shaped plate 34 is welded and fixed to the mounting block fixed to the center line of the spring 33. When the limit block 1 31 and the limit block 2 32 welded on both sides of the spring 33 perform horizontal and transverse telescopic movements under the elastic action of the spring 33, the fixed shaped plate 34 will remain on the surface of the limit block 1 31 and the limit block 2 32 that is in contact with the pre-reserved hole steel barrel, playing the role of supporting the pre-reserved hole steel barrel, and further achieving a good clamping and fixing effect.

[0032] In one embodiment, the adjustment component 4 includes a sleeve 41 provided on the outside of the profile frame 2 and having openings at both ends, two screw rods 42 provided on the sleeve 41 and slidably connected to the openings at both ends, and a fastening stud 43 for fixing the relative distance between the screw rod 42 and the opening on one side of the sleeve 41 provided on the outer wall of the sleeve 41 and corresponding to the screw rod 42. In this design, the two screw rods 42 are slidably connected by slots at both ends of the openings on the sleeve 41, and the fastening stud 43 is rotatably connected by the internal thread grooves machined on the outer wall of the sleeve 41, wherein the end of the fastening stud 43 extending into the inner cavity of the sleeve 41 will abut against the outer wall of the screw rod 42, thereby achieving the fixing effect of the screw rod 42 on the sleeve 41, determining the relative distance between the screw rod 42 and the opening on one end of the sleeve 41, and realizing the spacing adjustment function of the two adjacent groups of limit components 3.

[0033] It should be noted that after the screw rods 42 slidingly connected at both ends of the sleeve 41 are fixed using the fastening studs 43, rotating the screw rod 42 on one side will drive the screw rod 42 on the other side to rotate synchronously, thereby realizing the synchronous adjustment function of the spacing adjustment of the limit components 3 in groups of two, thereby improving efficiency.

[0034] In one embodiment, the adjustment assembly 4 further includes two support plates 44 disposed on the screw rod 42 and fixed to the sides of the corresponding limit blocks 32. With this design, the support plates 44 welded to the sides of the limit blocks 32 and the internal thread grooves machined on the support plates 44 are mated with the external threads machined on the upper surface of the screw rod 42. When the screw rod 42 is rotated, the generated rotational force drives the limit blocks 32 welded to the threaded support plates 44 to adjust the horizontal and vertical distances between the mold frame 1 and the mold frame 2.

[0035] It should be noted that two sections of threads with opposite directions are machined on the screw rod 42. This design can achieve the relative distance adjustment of a group of two limit assemblies 3 that are threaded on one side of the screw rod 42.

[0036] In one embodiment, the adjacent ends of the profile frame 1 and the profile frame 2 are not connected. This design ensures that there is no length restriction during the horizontal adjustment of the spacing by not connecting the profile frame 1 and the profile frame 2.

[0037] In one embodiment, an L-shaped connecting plate 5 is fixed to the bottom ends of the profile frame 1 and the profile frame 2. In this design, the L-shaped connecting plate 5 welded at the bottom ends of the profile frame 1 and the profile frame 2 plays a guiding and supporting role.

[0038] In one embodiment, the pier top formwork is provided with a slide groove 6 for cooperating with the movement of the L-shaped connecting plate 5. This design allows the positioning fixture of this embodiment for securing the pre-hole steel drum to be adjusted horizontally on the pier top formwork by turning the slide groove 6 on the pier top formwork to cooperate with the movement of the L-shaped connecting plate 5, making it easy to operate.

[0039] It should be noted that a rubber sheet is pasted on the inner wall of the slide groove 6, which has a damping property and reduces the sliding that occurs when no external force is applied.

[0040] In one embodiment, the end surface of the molded frame 2 is provided with a notch 7 for the rotation of the fastening stud 43. This design, through the notch 7 machined through the end surface of the molded frame 2, allows the fastening stud 43, which is connected to the sleeve 41 and protrudes from the original plane, to be located within the groove of the notch 7 when the screw 42 rotates, ensuring that subsequent rotation operations will not interfere.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
