Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bridge construction equipment, specifically to a shaping frame for steel reinforcement skeletons of pier columns and cap beams. Background Technology
[0002] Pier cap beams are an important component of bridge structures, connecting piers and the bridge deck and transferring loads from vehicles. The construction of pier cap beams directly affects the stability of the bridge. The construction process typically includes pier construction, formwork installation, reinforcement cage binding, and concrete pouring. Among these steps, reinforcement cage binding requires specialized tools such as prefabricated jigs to help construction workers assemble and position the reinforcement on the ground. Existing prefabricated jigs for pier cap beam reinforcement cages have unreasonable outer frame and internal support structure designs, making them prone to damage during reinforcement cage shaping. Furthermore, the jig is a monolithic structure, meaning that the entire jig is scrapped if part of it is damaged, and transportation is inconvenient. Utility Model Content
[0003] The purpose of this utility model is to provide a shaping jig for steel reinforcement skeleton pieces of pier cap beams, so as to solve the problems mentioned in the background art, such as the unreasonable design of the outer frame and inner support structure of the existing jig, which is easy to be damaged during the shaping of steel reinforcement skeleton pieces; at the same time, the jig is an integral structure, and when part of it is damaged, the whole jig is scrapped, and transportation is inconvenient.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A sizing frame for reinforcing steel skeleton pieces of a pier cap beam includes an outer frame system, an inner support system, and connectors. The outer frame system includes a first sizing frame, a second sizing frame, and a third sizing frame. The first sizing frame is arranged according to the design shape of the reinforcing steel skeleton piece of the cap beam. The second sizing frame and the third sizing frame are arranged inside the first sizing frame. The inner support system is arranged inside the outer frame system. The inner support system includes vertical braces, diagonal braces, and corner braces. The two ends of the vertical braces abut against the inside of the sizing frame and are arranged longitudinally. The two ends of the diagonal braces abut against the inside of the sizing frame and are arranged diagonally, avoiding the vertical braces. The corner braces are located at the corners of the sizing frame. A set of outer frame system and inner support system are symmetrically connected to both sides of the connectors.
[0006] Furthermore, the outer frame system also includes limiting posts, which are evenly arranged on the outside of the first shaping frame and perpendicular to the axis of the first shaping frame.
[0007] Furthermore, both the second and third shaping frames are disposed close to the inner side of the lateral side of the first shaping frame, with the second shaping frame extending to the corner formed by the lateral side and the oblique side; and the third shaping frame extending to the lateral side near the oblique side.
[0008] Furthermore, the two ends of the vertical support abut against the second shaping frame and the third shaping frame.
[0009] Furthermore, the diagonal brace is located between the two transverse sides inside the outer frame system, and between one transverse side and one diagonal side; the two abutting ends of the diagonal brace extend in opposite directions.
[0010] Furthermore, the internal support system also includes positioning bars, a plurality of which are disposed inside the second and third shaping frames. Each positioning bar consists of a straight rod and a crossbar extending from one side of the straight rod.
[0011] Furthermore, the internal support system also includes a reinforcing rod, which is located at the connection point of the first shaping frame, the second shaping frame and the diagonal brace or at the connection point of the first shaping frame, the third shaping frame and the diagonal brace.
[0012] Furthermore, the connector is provided with a connecting device for connecting the two outer frame systems.
[0013] Furthermore, the connecting device is a snap-fit or a bolt.
[0014] Furthermore, the jig is used for shaping the steel reinforcement skeleton pieces of the pier cap beam.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The first, second, and third shaping frames of the outer frame system serve as the basis for the overall shape of the steel reinforcement skeleton. The limiting columns are evenly arranged on the outside of the first shaping frame and perpendicular to the axial direction, which restricts the deformation of the first shaping frame in the direction perpendicular to the axial direction when the steel reinforcement skeleton is bent and shaped.
[0017] 2. The vertical braces of the internal support system abut against the second and third shaping frames at both ends, providing longitudinal support to the interior of the frame and preventing deformation in the longitudinal direction. The diagonal braces provide support from the diagonal direction, sharing the stress on the frame and enhancing the overall stability of the frame. The corner braces are located at the corners of the outer frame system to reduce deformation at the corners when the steel skeleton is bent and shaped. The positioning bars are located inside the second and third shaping frames to position and support the internal structure. The reinforcing rods are located at the connection points of the three components to enhance the strength of the connection points and improve the stability of the entire internal support system.
[0018] 3. A set of outer frame system and inner support system are symmetrically connected on both sides of the connector, so that the outer frame system and inner support system can be combined into a whole, which facilitates the assembly and disassembly of the jig, improves construction efficiency, and if a part is damaged or deformed, it can be replaced separately without replacing the entire jig, thus reducing construction costs.
[0019] In summary, compared with the prior art, this utility model has a more stable structure and is not easily deformed. Through the outer frame system, the inner support system and the connectors, it ensures that the steel reinforcement skeleton can be formed according to the designed shape and size.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1 As shown, a pier cap beam reinforcement skeleton forming frame includes an outer frame system 100, an inner support system 200, and a connector 300. The outer frame system 100 includes a first forming frame 110, a second forming frame 120, and a third forming frame 130. The first forming frame 110 is set according to the design shape of the cap beam reinforcement skeleton. The second forming frame 120 and the third forming frame 130 are provided inside the first forming frame 110. The inner support system 200 is provided inside the outer frame system 100. The inner support system 200 includes a vertical brace 210, a diagonal brace 220, and a corner brace 230. The two ends of the vertical brace 210 abut against the inside of the forming frame and are arranged longitudinally. The two ends of the diagonal brace 220 abut against the inside of the forming frame and are arranged diagonally away from the vertical brace 210. The corner brace 230 is provided at the corner of the forming frame. The connector 300 symmetrically connects a set of outer frame system 100 and inner support system 200 on both sides.
[0024] like Figure 1 As shown, the outer frame system 100 further includes limiting posts 140, which are evenly arranged on the outside of the first shaping frame 110 and perpendicular to the axis of the first shaping frame 110.
[0025] like Figure 1As shown, the second shaping frame 120 and the third shaping frame 130 are both arranged close to the inner side of the lateral side of the first shaping frame 110. The second shaping frame 120 extends to the corner formed by the lateral side and the oblique side; the third shaping frame 130 extends to the lateral side near the oblique side. The second shaping frame 120 and the third shaping frame 130 are mainly used for shaping the skeleton piece and providing lateral support to prevent the steel skeleton from deforming laterally during the forming process.
[0026] like Figure 1 As shown, the vertical support 210 abuts between the second shaping frame 120 and the third shaping frame 130 at both ends, and the vertical support 210 provides vertical support to stabilize the shape of the skeleton piece in the longitudinal direction.
[0027] like Figure 1 As shown, the diagonal brace 220 is located between the two transverse sides and between one transverse side and one diagonal side inside the outer frame system 100; the two abutting ends of the diagonal brace extend in opposite directions, so that the frame remains stable under external force during the shaping process of the skeleton piece.
[0028] like Figure 1 As shown, the internal support system 200 also includes positioning bars. A plurality of positioning bars are disposed inside the second shaping frame 120 and the third shaping frame 130. Each positioning bar consists of a straight rod and a horizontal bar extending from one side of the straight rod. The positioning bar 240 is used to bind and position the skeleton piece.
[0029] like Figure 1 As shown, the internal support system 200 also includes a reinforcing rod 250, which is located at the connection point of the three components: the first shaping frame 110, the second shaping frame 120, and the diagonal brace 220, or at the connection point of the three components: the first shaping frame 110, the third shaping frame 130, and the diagonal brace 220. The reinforcing rod 250 is located at the joint of the three components to ensure that the relative positions of the three components remain stable.
[0030] In actual implementation, the connector 300 is equipped with a connecting device for connecting the two outer frame systems 100. Connecting the two outer frame systems 100 through the connector 300 is more modular than the overall frame structure, which facilitates transportation, storage and reuse. Furthermore, if a part is damaged or deformed, it can be replaced individually without replacing the entire frame, thus reducing construction costs.
[0031] In practice, the connecting device is a snap fastener or a bolt.
[0032] In practice, the formwork is used to shape the steel reinforcement skeleton of the pier column cap beam.
[0033] In actual implementation, a 1:1 modeling frame is set up in the steel bar yard at the construction site according to the design drawing parameters. Steel bars of the designed length are cut and placed on the frame. They are then bent according to the shape of the frame. Stirrups are used to fix the frame at the position of the frame corresponding to the positioning rod 240. The designed connection points of the steel bar frame are welded evenly. The welding sequence is symmetrical from the center to both ends. The lower part of the frame is welded first, followed by the upper part.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
