Description

Technical Field

[0001] This utility model relates to the field of beam-column joint hole positioning technology, specifically a beam-column joint hole positioning device for a type of steel structure in a subway vehicle base. Background Technology

[0002] Construction of steel structure beam-column joints is widely used in various building and municipal engineering projects. It is mainly constructed by welding or sleeve connection. The construction of steel structure beam-column joints in large subway vehicle depots mainly adopts the joint construction of steel structure processing plants with strong design capabilities and professional steel bar processing teams. At the same time, BIM is used for modeling in advance to ensure both construction progress and quality and safety.

[0003] However, due to the constraints of high-voltage line relocation, the actual construction period of the main structure at the existing base is shortened. There are many constraints on the construction of conventional steel column-beam joints, resulting in a long construction time and significant on-site schedule pressure. Metro vehicle bases generally have a large number of steel bars in beams and columns. If conventional welding is used for the steel column-beam joints, there are many constraints on the construction personnel, making quality control difficult. If sleeve connections are used, deviations are likely to occur between factory processing and on-site construction positions, making it difficult to control the connection quality and ensuring the overall construction quality. There are also problems such as difficulty in locating beam-column joint holes and large connection gaps at the steel structure beam-column joints, which increase the welding difficulty. Therefore, it is necessary to provide a positioning device for beam-column joint holes in metro vehicle bases. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for the joint holes of steel structure beams and columns in subway vehicle bases, so as to solve the problems of numerous construction constraints of existing devices and the difficulty in controlling the connection quality due to deviations that easily occur when the factory is processed at the construction site.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for beam-column joint holes in a steel structure of a subway vehicle depot, comprising a base plate, wherein a positioning mechanism is provided on the upper side of the base plate; the positioning mechanism comprises two support rods, which are slidably installed inside the base plate; a first buckle is fixedly installed on both sides of the base plate; a first buckle frame is fixedly installed inside the first buckle; a second buckle is fixedly installed between the two first buckle frames; a first bolt is threaded onto the first buckle frame; a second buckle frame is fixedly installed inside the second buckle; a positioning pin is fixedly installed on one side of the second buckle frame; and a second bolt is threaded onto the second buckle frame.

[0006] Preferably, both the first buckle and the second buckle are composed of several U-shaped plates arranged side by side, and the middle of both sides of the U-shaped plates are concave inward.

[0007] Preferably, both sides of the lower part of the first buckle and the second buckle are provided with protrusions, and the middle part of the first buckle and the second buckle is provided with grooves.

[0008] Preferably, one end of the No. 1 bolt and the No. 2 bolt are rotatably installed on one side of the No. 1 buckle and the No. 2 buckle, respectively, and one end of the positioning pin is provided with an arc-shaped groove.

[0009] Preferably, the second buckle is provided with an outlining mechanism, which includes two support frames. Outlining folding rods are fixedly installed on both sides of the two support frames, and two buckle plates are fixedly installed side by side on the lower part of the support frames. A third bolt is threaded on the support frame, and a pressure plate is rotatably installed on one end of the third bolt.

[0010] Preferably, one side of the buckle plate is provided with a protrusion, and the other side of the buckle plate is provided with a slope, and both sides of the pressure plate are adapted to the slope.

[0011] Preferably, triangular plates are fixedly installed between the first buckle and the second buckle seat, as well as between the second buckle and the positioning pin, the support frame, and the tracing folding rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) The positioning device for the beam-column joint hole of the subway vehicle depot steel structure uses a support rod to adjust the support plate on the beam and column. Then, several No. 2 fasteners and positioning pins are fastened to the No. 1 fastener and No. 2 fastener respectively through the No. 1 fastener and No. 2 fastener. The steel bars on the beam and column are clamped by two positioning pins. The No. 1 bolt and No. 2 bolt are fixed by several positioning pins, thus completing the positioning of the beam-column joint hole. Later, steel plates are processed according to the positioning pins on the device to obtain a steel structure that matches the beam-column joint, which facilitates the construction of the beam-column joint of the steel structure.

[0013] 2) The positioning device for the joint holes of the steel structure beams and columns in this subway vehicle depot uses two buckles to fasten several outlined folded rods to the No. 2 buckle seat, so that the outlined folded rods are close to the edge of the beams and columns. The No. 3 bolt is then controlled to move the pressure plate downward along the two buckles, thus completing the positioning of the edge of the beams and columns. Later, steel plates are processed according to the outlined folded rods on the device to obtain a steel structure that matches the edge of the beams and columns, making the connection of the steel structure beams and columns tighter and reducing the welding difficulty at the joint.

Detailed Implementation

[0016] 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.

[0017] Example 1 Combination Figures 1-4 A positioning device for the joint holes of steel beams and columns in a subway vehicle base includes a base plate 1, and a positioning mechanism 2 is provided on the upper side of the base plate 1. The positioning mechanism 2 includes two support rods 201, which are slidably installed inside the base plate 1. A first buckle seat 202 is fixedly installed on both sides of the base plate 1. A first buckle bracket 203 is fastened inside the first buckle seat 202. A second buckle seat 204 is fixedly installed between the first buckle brackets 203 on both sides. A first bolt 205 is threaded on the first buckle bracket 203. A second buckle bracket 206 is fastened inside the second buckle seat 204. A positioning pin 207 is fixedly installed on one side of the second buckle bracket 206. A second bolt 208 is threaded on the second buckle bracket 206.

[0018] Both buckle base 202 and buckle base 204 are composed of several U-shaped plates arranged side by side, with the middle of both sides of the U-shaped plates recessed inwards. Both sides of the lower part of buckle frame 203 and buckle frame 206 have protrusions, and the middle of buckle frame 203 and buckle frame 206 has a groove. One end of bolt 205 and bolt 208 are rotatably mounted on one side of buckle frame 203 and buckle frame 206, respectively. One end of positioning pin 207 has an arc-shaped groove. Benefiting from the shape of buckle base 202 and buckle base 204, buckle base 202 and buckle base 204 possess relatively... Good flexibility allows for clamping of buckle 1 203 and buckle 206. When buckle 1 203 and buckle 206 are clamped on buckle 1 202 and buckle 204, further rotation of bolt 1 205 and bolt 208 can open buckle 1 203 and buckle 206, thus fixing buckle 1 203 and buckle 206. In use, by adjusting the positions of buckle 1 203 and buckle 206 on buckle 1 202 and buckle 204 respectively, the two positioning pins 207 clamp the reinforcing bar, thereby positioning the reinforcing bar.

[0019] Example 2 See Figures 5-7 The second buckle 204 is provided with an outlining mechanism 3. The outlining mechanism 3 includes two support frames 301. Outlining folding rods 302 are fixedly installed on both sides of the two support frames 301. Two buckle plates 303 are fixedly installed side by side on the lower part of the support frame 301. A third bolt 304 is threaded on the support frame 301. A pressure plate 305 is rotatably installed on one end of the third bolt 304.

[0020] One side of the buckle plate 303 has a protrusion, and the other side of the buckle plate 303 has a slope. Both sides of the pressure plate 305 are adapted to the slope. Triangular plates are fixedly installed between the first buckle bracket 203 and the second buckle seat 204, as well as between the second buckle bracket 206 and the positioning pin 207, and between the support bracket 301 and the outlining folding rod 302. Benefiting from the shape of the buckle plate 303, the pressure plate 305, and the second buckle seat 204, when the two buckle plates 303 are clamped between the second buckle seat 204, the third bolt 304 is further controlled to make the pressure plate 305 move along the two buckle plates. The two buckles 303 move downwards, thus opening up the two buckle plates 303 and fixing the support frame 301. In use, by adjusting the position of the support frame 301 on the second buckle seat 204, the tracing rod 302 is made to be close to the edge of the beam and column, so that the beam and column can be traced. The triangular plate plays a supporting role, so that the first buckle 203, the second buckle 206 and one side of the support frame 301 are always fixed, and the positioning pin 207 and the tracing rod 302 are prevented from tilting due to the influence of the first bolt 205, the second bolt 208 and the third bolt 304.

[0021] In actual operation, the first buckle 203 and the second buckle 206 are clamped on the first buckle seat 202 and the second buckle seat 204. Further rotation of the first bolt 205 and the second bolt 208 can open the first buckle 203 and the second buckle 206, thus fixing the first buckle 203 and the second buckle 206. When in use, by adjusting the positions of the first buckle 203 and the second buckle 206 on the first buckle seat 202 and the second buckle seat 204 respectively, the two positioning pins 207 clamp the steel bar, thus positioning the steel bar. The two buckle plates 303 are clamped between the second buckle seat 204. The third bolt 304 is further controlled to make the pressure plate 305 move downward between the two buckle plates 303, thereby opening the two buckle plates 303 and fixing the support frame 301. In use, by adjusting the position of the support frame 301 on the second buckle seat 204, the tracing rod 302 is made to be close to the edge of the beam and column, so that the beam and column can be traced.
