Description

Technical Field

[0001] The utility model relates to the field of assembled steel bar component assembly, in particular to an assembled steel bar component rigid frame. Background Art

[0002] With the advancement of science and technology, the steel bar construction of bridge projects has gradually moved from on-site manual loose binding to the assembly construction stage. At present, there are two main routes for the construction of tower and pier steel bar components. One is to weld the main bars and stirrups of the steel bar components to form a whole, and then connect the main bars between segments through mechanical connectors such as cone sleeves. This method has relatively high steel bar construction efficiency, but the price of mechanical connectors suitable for this main bar connection is more than ten times that of ordinary straight threads, which brings large additional costs to production. At present, horizontal matching is used for piers with smaller cross-sectional sizes through straight thread sleeves, but the process of making steel bar components is cumbersome, and due to the inevitable deformation during the hoisting process, it is difficult to connect the main bars, affecting the construction progress and project quality. Therefore, an assembled rigid skeleton of steel bar components is proposed to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide an assembled rigid frame for steel bar components. The assembled rigid frame is used for manufacturing and hoisting steel bar components, which can not only solve the problem of high cost of mechanical connection using cone sleeves, but also solve the problem of low production efficiency and difficult main reinforcement connection caused by horizontal matching of straight threaded sleeves.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a steel bar component assembled rigid skeleton, including a frame-type skeleton structure, the top of the frame-type skeleton structure is provided with an upper and lower layer of staggered main reinforcement positioning support structure, the frame-type skeleton structure is provided with a plurality of stirrups and hook reinforcement limiting mechanisms, and the outside of the frame-type skeleton structure is also provided with a plurality of stirrup comb rods, wherein the main reinforcement positioning support structure is composed of two symmetrically arranged clamping blocks, and the spacing between the two clamping blocks is greater than the diameter of the main reinforcement of the steel bar component, and smaller than the diameter of the straight threaded sleeve at the end of the main reinforcement of the steel bar component.

[0005] In a preferred embodiment, the stirrup and hook reinforcement limiting mechanism comprises a plurality of extension rods longitudinally arranged on the frame-type skeleton structure, and stirrup limiting plates and hook reinforcement limiting plates respectively arranged at both ends of the extension rods.

[0006] In a preferred embodiment, the stirrup comb tooth rod includes a vertical rod and a plurality of limiting teeth equidistantly arranged on the side of the vertical rod.

[0007] In the preferred embodiment, the stirrup comb rod is detachably installed on the side of the frame-type skeleton structure, wherein a plurality of L-shaped grooves are arranged on the vertical rod, and a plurality of pins which can pass through the L-shaped grooves are arranged on the frame-type skeleton structure, and the pins correspond to the L-shaped grooves one by one.

[0008] In the preferred embodiment, the pin shaft includes an outer sleeve shaft body with an open front end, and a plurality of telescopic cavities are arranged on the outer wall at the end of the outer sleeve shaft body. The cross-section of the telescopic cavity is convex, and a resistance block is telescopically arranged in the telescopic cavity. The resistance block is located at one end of the outer sleeve shaft body and is sloped, and limit blocks matching the telescopic cavity are arranged on both sides of the other end. The open end of the outer sleeve shaft body is plugged with the resistance shaft body, and the front end of the resistance shaft body is bucket-shaped that matches the slope of the bottom of the resistance block, and a shaft head is arranged at the end.

[0009] In a preferred embodiment, two slide grooves are arranged on the inner wall surface of the outer sleeve shaft body, and two sliding blocks which are respectively slidably connected with the two slide grooves are arranged on the outer wall surface of the abutting shaft body.

[0010] The utility model provides an assembled rigid frame for steel bar components, through which horizontal stirrups and hook bars are positioned and main bars are limited vertically. Since the main bars can move freely within a certain range when the steel bar components are hoisted and connected, the problem of difficult connection with ordinary straight threaded sleeves using a matching method is solved, thereby improving construction efficiency and ensuring engineering construction quality.

DETAILED DESCRIPTION

[0025] Example 1

[0026] like Figure 1-6 As shown, a steel bar component assembled rigid skeleton includes a frame-type skeleton structure 1. The top of the frame-type skeleton structure 1 is provided with an upper and lower staggered main reinforcement positioning support structure 2, which is used to suspend the top of the main reinforcement on the main reinforcement positioning support structure 2, so as to limit the main reinforcement in the horizontal direction and prevent it from falling in the vertical direction. At the same time, the steel bar components are assembled on site, and the main reinforcement has a certain degree of freedom, which is convenient for connection, and there is no quality problem such as main reinforcement not being able to be connected. The upper and lower staggered main reinforcement positioning support structure 2 can meet the requirement of staggered sections when the steel bars are connected. A plurality of stirrups and hook reinforcement limiting mechanisms 3 are provided on the frame-type skeleton structure 1, which are used for horizontal plane limiting when the stirrups and hook reinforcement are installed. A plurality of stirrup comb rods 4 are also provided on the outside of the frame-type skeleton structure 1 for positioning the stirrups in the vertical direction, wherein the main reinforcement positioning support structure 2 is composed of two symmetrically arranged clamping blocks 202, the spacing between the two clamping blocks 202 is larger than the diameter of the main reinforcement of the steel bar component, and smaller than the diameter of the straight thread sleeve at the end of the main reinforcement of the steel bar component, so that the main reinforcement is conveniently suspended between the two clamping blocks 202 through the straight thread sleeve pre-installed on the top thereof, and the upper end of the main reinforcement is suspended on the upper end of the frame-type skeleton structure 1 and can move freely. Since the main reinforcement is only temporarily fixed by vertical constraints, there is no quality problem such as the main reinforcement not being properly connected when the steel bar component is hoisted and connected.

[0027] In this embodiment, each layer of main reinforcement positioning support structure (2) is distributed on both inner and outer sides of the frame-type skeleton structure (1).

[0028] In the preferred embodiment, the stirrup and hook bar limiting mechanism 3 includes a plurality of extension rods 301 longitudinally arranged on the frame-type skeleton structure 1, and stirrup limiting plates 302 and hook bar limiting plates 303 respectively arranged at both ends of the extension rods 301. The stirrup limiting plates 302 and hook bar limiting plates 303 are both long strip angle steels. When installing the stirrups and hook bars, the horizontal plane limitation is achieved through contact with the stirrup limiting plates 302 or the hook bar limiting plates 303.

[0029] In the preferred embodiment, the stirrup comb tooth rod 4 includes a vertical rod 401 and a plurality of limiting teeth 402 equidistantly arranged on the side of the vertical rod 401. The number of the limiting teeth 402 and the spacing between them are adapted to the number and distribution requirements of the stirrups. Vertical positioning is achieved by placing the stirrups on each limiting tooth 402.

[0030] In the preferred embodiment, the stirrup comb rod 4 is detachably installed on the side of the frame-type skeleton structure 1, so that the stirrup comb rod 4 can be repeatedly used, wherein a plurality of L-shaped grooves 403 are arranged on the vertical rod 401, and a plurality of pins 404 that can penetrate the L-shaped grooves 403 are arranged on the frame-type skeleton structure 1, and the pins 404 correspond to the L-shaped grooves 403 one by one. In this embodiment, the number of L-shaped grooves 403 and the number of pins 404 are both three. When installing, the pins 404 are inserted into the horizontal notch of the L-shaped groove 403. When removing, the stirrup comb rod 4 only needs to be knocked with a tool to move it. When the pins 404 enter the vertical notch of the L-shaped groove 403 of the stirrup comb rod 4, the comb rod 4 is separated from the stirrup and can be taken out.

[0031] Example 2

[0032] Further illustrate with reference to Example 1, Figure 9-12 The structure shown is a method for assembling a steel bar component assembled rigid frame, the method comprising:

[0033] S1, rigid skeleton positioning, such as Fig. 9 As shown in the figure, the rigid frame needs to be positioned and installed in correspondence with the positioning tooling at the lower end of the main reinforcement, and then it is firmly fixed on the ground. Since the steel bar parts are generally high in sections, a manual operation platform is also required;

[0034] S2. Installation of main reinforcement, such as Fig.10 As shown, the main reinforcement is cut by CNC equipment in the reinforcement factory and the end is threaded as required, then a straight thread sleeve is installed on one end, and the thread is protected by a protective sleeve on the other end. The main reinforcement is transported to the site, and a lifting device is used to erect the end of the main reinforcement with the straight thread sleeve upward and against the rigid frame, and then it is manually installed one by one on the main reinforcement positioning support structure 2, and at the same time, the lower end of the main reinforcement is inserted into the corresponding positioning hole of the main reinforcement lower end positioning tooling.

[0035] S3, installation of stirrups and hook bars, such as Fig.11 As shown, according to the design requirements, stirrups are first installed. The stirrups are plane-limited by the stirrup limiting plates 302 on the rigid frame, and the stirrups are vertically positioned by the stirrup comb rods 4; then the hook bars are installed. After all stirrups and hook bars are installed and positioned, the stirrups and hook bars are connected by welding or tying with wire, and then the stirrups are partially spot-welded on the rigid frame, so that all stirrups and hook bars are firmly connected to the rigid frame to form the overall shape of the steel bar component, and then the lower end of the main bar is temporarily fixed to the stirrups by tying wire to avoid the lower end of the main bar shaking at will during lifting.

[0036] S4. Remove the stirrup comb rod. The stirrup comb rod 4 is connected to the rigid frame through the pin 404. During installation, insert the stirrup comb rod 4 into the fixing pin 9 on the rigid frame. During disassembly and assembly, just use a tool to knock the stirrup comb rod 4 to move it to the right. When the pin 404 enters the L-shaped vertical notch of the stirrup comb rod 4, the comb rod 4 is detached and can be taken out.

[0037] At this point, the production of steel bar components based on the assembled rigid frame is completed.

[0038] Example 3

[0039] Further illustrate with reference to Examples 1 and 2, Figure 7-8 In order to improve the stability of the connection between the stirrup comb rod 4 and the rigid frame, the pin 404 includes a sleeve shaft body 4041 with an open front end, and a plurality of telescopic cavities 4042 are arranged on the outer wall of the end of the sleeve shaft body 4041. In this embodiment, the number of the telescopic cavities 4042 is three, and the cross section of the telescopic cavity 4042 is convex. A resisting block 4043 is retractably arranged in the telescopic cavity 4042, and the resisting block 4043 is located at one end of the sleeve shaft body 4041. The slope between the three abutment blocks 4043 forms a bucket shape, and the two sides of the other end are provided with limit blocks 4044 adapted to the telescopic cavity 4042, so that when the abutment block 4043 falls back, the limit blocks 4044 fall into the telescopic cavity 4042 to play a limiting role, and the open end of the outer sleeve shaft body 4041 is plugged with a resistance shaft body 4045, and the front end of the resistance shaft body 4045 is bucket-shaped adapted to the bottom slope of the resistance block 4043, and the end is provided with a shaft head 4046.

[0040] When in use, after the stirrup comb tooth rod 4 is installed, use external force to resist the shaft head 4046, and use the forward movement of the bucket-shaped end of the resistance shaft body 4045 to resist each resistance block 4043, so that the resistance block 4043 extends out of the outer surface of the outer sleeve shaft body 4041, thereby expanding the outer diameter of the pin shaft 404 and contacting the inner wall of the L-shaped groove 403, thereby playing a reinforcement role and avoiding unnecessary sliding during use, resulting in displacement of the stirrup comb tooth rod 4. When the stirrup comb tooth rod 4 needs to be removed, use external force to pull out the shaft head 4046, release the connection between the resistance shaft body 4045 and each resistance block 4043, and then remove the stirrup comb tooth rod 4.

[0041] In the preferred embodiment, two sliding grooves 4047 are provided on the inner wall surface of the outer sleeve shaft 4041, and two sliding blocks 4048 are provided on the outer wall surface of the resistance shaft 4045, which are respectively slidably connected to the two sliding grooves 4047, thereby limiting the sliding range of the resistance shaft 4045 to prevent it from falling off.

[0042] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
