Description

Technical Field

[0001] The utility model relates to a ruler, in particular to an assembled culvert prefabricated component installation positioning caliper. Background Art

[0002] Culverts have become an important part of highway construction. With the continuous improvement of highway construction technology, culvert construction methods have also developed from cast-in-place methods to prefabricated assembly methods. At present, prefabricated culverts have been widely used in domestic highways to meet their drainage, passage and other functional requirements. Prefabricated culvert components are prefabricated in the factory and transported to the site for installation. They have the characteristics of high degree of factoryization and standardization, convenient on-site assembly operation, and fast lifting and transportation operation process. In order to meet the efficient installation of finished prefabricated components and present a neat appearance, higher requirements are put forward for on-site transportation and installation technology.

[0003] According to the conventional installation method of the side wall panels of the prefabricated culvert, the construction workers need to measure and lay out the center line of the culvert and the side wall installation edge line on the bottom plate foundation surface according to the requirements of the design drawings, and draw ink lines in sequence and continuously. As a result, the installation of prefabricated components for long-distance culverts requires repeated layout, and the cumbersome process leads to reduced work efficiency. At the same time, the conditions for field operation transportation and hoisting are poor, which increases the difficulty of quality control of prefabricated component installation. Summary of the invention

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model discloses an assembly type culvert prefabricated component installation positioning caliper, comprising a triangular bracket, a telescopic component is installed on the upper end of the triangular bracket, positioning clamping plates are fixed at both ends of the telescopic component, and the positioning clamping plates are clamped with the bottom edge surface of the side wall plate.

[0007] The telescopic assembly includes a plurality of support sleeves, each of which is provided with a plurality of adjustment screw holes, and adjacent support sleeves are sleeved and locked by connecting bolts.

[0008] The support sleeve is made of a square tube.

[0009] The telescopic assembly is divided into two sections, one end of each section is hinged to the triangular bracket and locked by a latch.

[0010] The triangular bracket is made of round steel bent into a triangular structure.

[0011] A pin hole seat plate is welded on the upper end of the triangular bracket.

[0012] The utility model provides a prefabricated culvert component installation positioning caliper, which has the following technical effects:

[0023] like Figure 1-2 As shown, a prefabricated component installation positioning caliper for assembled culverts includes a triangular bracket 2, a telescopic component 1 is installed on the upper end of the triangular bracket 2, and positioning clamps 3 are fixed at both ends of the telescopic component 1. The positioning clamps 3 are clamped with the bottom edge surface of the side wall panel 9.

[0024] like Figure 1-2As shown, the telescopic assembly 1 includes a plurality of support sleeves 1.1, which are made of square tubes, and a plurality of adjusting screw holes 1.2 are drilled at equal intervals on each support sleeve 1.1. Adjacent support sleeves 1.1 are sleeved, and then the connecting bolts 4 are screwed into the overlapping adjusting screw holes of the two support sleeves 1.1 for locking. The telescopic assembly 1 can be conveniently adjusted according to the change of the span size of the culvert.

[0025] like Figure 3-5 As shown, the telescopic assembly 1 is divided into two sections, one end face of the two sections is hinged to the triangular bracket 2 and locked by a latch 5. In this way, the telescopic assembly 1 can be folded, which is convenient for later storage and carrying. The specific hinge relationship is that a latch hole base plate 6 is welded on the upper end of the triangular bracket 2, and a rotating shaft screw 7 is fixed on one end of the latch hole base plate 6 in a direction perpendicular to the telescopic assembly 1. The rotating shaft screw 7 is rotatably sleeved with the shaft sleeves on the left and right sections of the telescopic assembly 1 and the upper end is limited by a nut, so that the left and right sections of the telescopic assembly 1 can rotate relative to the rotating shaft screw 7. A collar 8 is welded on the other end of the latch hole base plate 6 in a direction perpendicular to the telescopic assembly 1, and a collar 8 is also welded on the left and right sections of the telescopic assembly 1. When the left and right sections of the telescopic assembly 1 are located on the same straight line, the latch 5 is inserted to achieve locking, which can ensure the normal use of the device. After the work is completed, the latch 5 can be pulled out, and the left and right sections of the telescopic assembly 1 can be folded, so that the entire positioning caliper rod can be flexibly disassembled and moved on site.

[0026] The triangular bracket 2 is made of round steel bent into a triangular structure, which is used to support the telescopic component 1 and the ground. When in use, the bottom round steel of the two sets of triangular brackets 2 coincides with the center line of the ground, ensuring that the two sets of triangular brackets are on the same center line.

[0027] like Figure 3-5 As shown, the positioning card plate 3 is welded by three small steel plates to form a ┌┐-shaped card plate, which is placed at the two ends of the prefabricated side wall plate 9. The positioning card plate 3 can fit tightly with the bottom edge surface of the side wall plate 9, and has the functions of stable support and adjustment and positioning.

[0028] Working principle and process: When installing the standard section side wall panels of the assembled culvert on site, strictly follow Figure 3 As shown in the figure, two sets of positioning calipers are respectively placed on the front and rear ports of the side wall panel 9 and aligned. The positioning calipers are adjusted to meet the span size requirements of the culvert and then locked. The triangular bracket 2 is aligned with the central axis of the culvert ground (which has been laid out and marked). The diagonal errors of the two sets of positioning calipers are measured. The side wall panel 9 can be quickly positioned with a slight adjustment.

[0029] During general structural installation or production, diagonal testing is required to prevent the formation of parallelograms or prisms.
