Description

Technical Field

[0001] This utility model relates to the technical field of bottom support plates for steel cages, specifically a bottom support plate for a core-filled concrete steel cage. Background Technology

[0002] A steel reinforcement cage is a skeletal component used in building construction to enhance the strength of concrete structures. It is a grid structure formed by welding or binding steel bars. Its components include main bars, spiral stirrups, and a base plate.

[0003] The aforementioned devices lack a quick-connection bottom support plate and a seepage-proof structure at the bottom of the pile hole. This means that the connection between the bottom support plate and the existing reinforcing cage is mostly done by welding, which is cumbersome and makes precise control of the welding position impossible. Furthermore, when the bottom support plate and reinforcing cage are placed into the pile hole, because the bottom support plate needs to be roughly the same size as the pile hole diameter, the bottom support plate easily comes into contact with the uneven inner wall of the pile hole after placement, becoming stuck and unable to continue downwards. Additionally, due to the poor flatness of the bottom of the pile hole and the inability to control the bottom diameter, concrete easily flows out from the gap between the bottom support plate and the pile hole to below the bottom support plate after the reinforcing cage and bottom support plate are fully placed into the pile hole. Based on the shortcomings of existing technology, this utility model designs a core-filled concrete reinforcing cage bottom support plate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bottom support plate for a core-filled concrete rebar cage, which has the advantages of quick connection of the bottom support plate and seepage prevention at the bottom of the pile hole.

[0005] This utility model provides the following technical solution: a bottom support plate for a core-filled concrete rebar cage, including main reinforcement bars, a bottom support plate body is provided at the bottom of the main reinforcement bars, and a fitting mechanism is provided at the bottom of the bottom support plate body to facilitate the main reinforcement bars and the bottom support plate body to lower the pile hole and prevent concrete leakage.

[0006] The bonding mechanism includes a bottom groove, a threaded groove, a rubber ring, a bottom hole, a screw, a reinforcing strip, and a bending groove. The bottom groove is located at the bottom of the base plate body, the threaded groove is located at the bottom of the bottom groove, the rubber ring is fixedly connected to the bottom groove, the bottom hole is located through the bottom of the rubber ring, the screw is inserted into the bottom hole, the reinforcing strip is fixedly connected to the upper surface of the rubber ring, and the bending groove is located on the reinforcing strip.

[0007] As a preferred technical solution of this utility model, a connecting seat is fixedly connected to the upper surface of the base plate body, a threaded sleeve is fixedly connected to the connecting seat, a shrinkage groove is provided on the threaded sleeve, a retaining strip is fixedly connected to the inner wall of the threaded sleeve, and a shrinkage groove is threadedly connected to the outer side of the threaded sleeve.

[0008] As a preferred embodiment of this utility model, the outer side of the main reinforcing bar is fixedly connected with stirrups.

[0009] As a preferred embodiment of this utility model, the rubber ring is fixedly connected to the base plate body.

[0010] As a preferred embodiment of this utility model, the screw passes through the bottom hole and is threaded into the threaded groove.

[0011] As a preferred technical solution of this utility model, the threaded hoop is narrow at the top and wide at the bottom, and the threaded hoop and nut are clamped and fixedly sleeved on the bottom end of the main reinforcement.

[0012] As a preferred embodiment of this utility model, the clamping strip is disposed on the main rib.

[0013] As a preferred embodiment of this utility model, the reinforcing strip and bending groove are arranged around the upper surface of the rubber ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This type of bottom support plate for core-filled concrete rebar cage involves placing the main body of the bottom support plate flat on the ground, then attaching nuts to the main reinforcing bars, and then vertically inserting the main reinforcing bars into the threaded ferrules. While keeping the main reinforcing bars vertical, the nuts are moved to thread them onto the ferrules. A wrench is then used to continuously tighten the nuts, causing the ferrules to compress inwards and reduce their inner diameter using their shape and shrinkage grooves. This tightened ferrules clamps and fixes the main reinforcing bars inside, while a retaining strip provides auxiliary positioning for the main reinforcing bars. This device facilitates the rapid connection of the bottom support plate to multiple main reinforcing bars.

[0016] 2. This type of bottom support plate for core-filled concrete reinforcing cage involves fixing a rubber ring to the bottom of the bottom support plate body, then vertically lifting the main reinforcement and the bottom support plate body into the pile hole. During the downward movement of the bottom support plate body, if the inner wall of the pile hole is uneven or the bottom support plate body shifts left or right, the rubber ring will first contact the inner wall of the pile hole and deform, thus providing auxiliary restraint for the main reinforcement and the bottom support plate body to prevent them from getting stuck against the inner wall of the pile hole and affecting the descent. After the bottom support plate body moves to the bottom of the pile hole, the rubber ring will also be in close contact with the bottom of the pile hole. If the bottom of the pile hole is slightly narrow, the rubber ring itself will bend upward at a certain angle under the pressure of the inner wall and fit against the inner wall. At the same time, the tightness of the fit between the rubber ring and the inner wall and bottom of the pile hole is improved under the support of the reinforcing strip. This device facilitates the placement of the main reinforcement and the bottom support plate body into the pile hole and prevents concrete from flowing out from the bottom of the bottom support plate body.

[0023] 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.

[0024] Please see Figure 1-5 A bottom support plate for a core-filled concrete rebar cage includes a main bar 1, a bottom support plate body 2 is provided at the bottom of the main bar 1, and a fitting mechanism 3 is provided at the bottom of the bottom support plate body 2 to facilitate the main bar 1 and the bottom support plate body 2 to lower the pile hole and prevent concrete leakage. Stirrups 101 are wrapped and fixedly connected to the outside of the main bar 1.

[0025] Please see Figure 4-5 The bonding mechanism 3 includes a bottom groove 301, a threaded groove 302, a rubber ring 303, a bottom hole 304, a screw 305, a reinforcing strip 306, and a bending groove 307. The bottom groove 301 is located at the bottom of the base plate body 2, the threaded groove 302 is located at the bottom of the bottom groove 301, the rubber ring 303 is fixedly connected to the bottom groove 301, the bottom hole 304 is located through the bottom of the rubber ring 303, the screw 305 is inserted into the bottom hole 304, the reinforcing strip 306 is fixedly connected to the upper surface of the rubber ring 303, the bending groove 307 is located on the reinforcing strip 306, the screw 305 passes through the bottom hole 304 and is threaded into the threaded groove 302, and the reinforcing strip 306 and the bending groove 307 are arranged in a circle on the upper surface of the rubber ring 303.

[0026] By setting the bottom groove 301, threaded groove 302, and rubber ring 303, the contact area between the bottom support plate body 2 and the pile bottom is expanded. At the same time, when the main reinforcement 1 and the bottom support plate body 2 are lowered into the pile hole, they can be positioned. This not only prevents the main reinforcement 1 and the bottom support plate body 2 from getting stuck in contact with the inner wall of the pile hole, but also reduces the diameter of the bottom support plate body 2. This prevents the bottom support plate body 2 of the same size as the pile hole from being unable to be fully inserted into the pile hole due to unevenness of the inner wall of the pile hole or other factors after it is installed at the bottom of the main reinforcement 1. By setting the rubber ring 303, reinforcing strip 306, and bending groove 307, the rubber ring 303 can be tightly fitted to the bottom of the pile hole. At the same time, when the diameter of the bottom of the pile hole is slightly smaller, the rubber ring 303 can be bent upwards to fit against the inner wall and bottom of the pile hole.

[0027] Please see Figure 3 A connecting seat 201 is fixedly connected to the upper surface of the base plate body 2. A threaded clamp 202 is fixedly connected to the connecting seat 201. A shrinkage groove 203 is provided on the threaded clamp 202. A retaining strip 204 is fixedly connected to the inner wall of the threaded clamp 202. A shrinkage groove 203 is threadedly connected to the outer side of the threaded clamp 202. The threaded clamp 202 is narrow at the top and wide at the bottom. The threaded clamp 202 and the nut 205 are clamped and fixedly sleeved on the bottom end of the main rib 1. The retaining strip 204 is clamped and set on the main rib 1.

[0028] By setting up a connecting seat 201, a threaded clamp 202, and a nut 205, and by providing a shrinkage groove 203 on the threaded clamp 202 with a shape that is narrower at the top and wider at the bottom, the threaded clamp 202 can continuously tighten inward and reduce its inner diameter after the nut 205 is fitted onto the threaded clamp 202 and continuously screwed downward, thereby clamping and fixing the main reinforcing bar 1 inserted into the threaded clamp 202. By setting a retaining strip 204, the connection strength of the main reinforcing bar 1 after being inserted into the threaded clamp 202 can be improved.

[0029] Working principle: When a core-filled concrete rebar cage bottom support plate is used, in the initial state, the stirrups 101 are first fixedly connected to multiple sets of main bars 1. The bottom end of the main bars 1 is inserted into the threaded cuff 202 set on the bottom support plate body 2. The threaded cuff 202 is provided with a shrinkage groove 203 and a nut 205 is sleeved on it, so as to quickly connect the bottom support plate body 2 and the main bars 1. In the bottom groove 301 opened at the bottom of the bottom support plate body 2, a rubber ring 303 is connected by a screw 305. The upper surface of the rubber ring 303 is provided with a reinforcing strip 306 with a bending groove 307 on the surface, so that the bonding mechanism 3 can always be kept in the unfolded state.

[0030] When it is necessary to quickly connect the base plate body 2 to multiple main ribs 1, first place the base plate body 2 flat on the ground, then put the nut 205 on the main rib 1, and then insert the main rib 1 vertically into the threaded sleeve 202. At this time, keep the main rib 1 in a vertical state and move the nut 205 to thread it onto the threaded sleeve 202. Then, use a wrench to continuously turn the nut 205 so that the threaded sleeve 202 is squeezed inward and its inner diameter is reduced by the shape of the threaded sleeve 202 and the shrinkage groove 203. The threaded sleeve 202, which has a reduced inner diameter, clamps and fixes the main rib 1 inside. At the same time, the clamping strip 204 is used to assist in limiting the main rib 1. This device facilitates the quick connection of the base plate body 2 to multiple main ribs 1.

[0031] When it is necessary to place the main reinforcement 1 and the bottom support plate body 2 into the pile hole and prevent concrete from flowing out from the bottom of the bottom support plate body 2, first, after the rubber ring 303 is fixed to the bottom of the bottom support plate body 2, the main reinforcement 1 and the bottom support plate body 2 are vertically lifted and placed into the pile hole. During the downward movement of the bottom support plate body 2, if the flatness of the inner wall of the pile hole is poor or the bottom support plate body 2 shifts left or right, the rubber ring 303 will first contact the inner wall of the pile hole and deform, thus providing auxiliary limiting for the main reinforcement 1 and the bottom support plate body 2 to prevent them from... The impact of the inner wall of the pile hole is reduced. After the bottom support plate body 2 moves to the bottom of the pile hole, the rubber ring 303 will also be in close contact with the bottom of the pile hole. If the bottom of the pile hole is slightly narrow, the rubber ring 303 will bend upward at a certain angle under the pressure of the inner wall and fit with the inner wall. At the same time, the tightness of the fit between the rubber ring 303 and the inner wall and bottom of the pile hole is improved under the support of the reinforcing strip 306. This device makes it easy to place the main reinforcement 1 and the bottom support plate body 2 in the pile hole and prevent concrete from flowing out from the bottom of the bottom support plate body 2.

[0032] 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 these 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.
