Abstract
Description
Technical Field
[0001] This utility model relates to a high-strength precast beam-column connection structure, belonging to the field of connection structure technology. Background Technology
[0002] With the continuous improvement of living standards, people have an increasing demand for residential and office buildings. During the construction process, it is usually necessary to fix the beams and columns. Currently, most beams and columns are made of cement, steel and wood. In order to make them stable and fixed, beam and column fixing devices have emerged in the field of beam and column fixing technology.
[0003] Chinese Patent Publication No. CN 211421410 U discloses a high-strength precast beam-column connection structure, specifically relating to the field of beam-column connection technology. The structure includes a box-shaped enclosure with a connecting mechanism inside. The connecting mechanism comprises two top plates, with a limiting post fixedly mounted at the bottom of each top plate. An outer plate is fixedly mounted inside each limiting post, and a first spring is fixedly mounted inside the outer plate. An inner plate is fixedly mounted at the other end of the first spring. This invention fixes the first, second, and third beam-columns by pressing down on the top plate, causing the second spring to retract, which in turn moves the inner plate downwards into a through-hole. The bottom end of the limiting post also enters the through-hole. For disassembly, pressing down on the horizontal plate causes the third spring to retract the inner plate, squeezing it into the box-shaped enclosure. Then, the second spring opens, causing the inner plate and the limiting post to move upwards. This design offers high efficiency and low workload.
[0004] The aforementioned device primarily relies on the tension of springs to connect and fix beams and columns. However, after prolonged use, the springs will lose their tension due to aging. At this point, the springs without tension may be unable to continue moving the components, which will affect the connection between beams and columns, leading to a decrease in the stability and firmness of the connection and thus affecting the normal use of the beams and columns in the future.
[0005] To address this, a high-strength precast beam-column connection structure is proposed. Utility Model Content
[0006] In view of this, the present invention provides a high-strength precast beam-column connection structure to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0009] The connecting assembly includes knobs, mounting plates, and reinforcing members. Two knobs are movably connected to the bottom of the two precast beams. A driving bevel gear is fixedly connected to the top of each knob. Driven bevel gears are movably connected to the left and right sides of the inner cavity of the first cavity. The surfaces of the driving bevel gears mesh with the surfaces of the driven bevel gears. A lead screw is fixedly connected to the outer side of the driven bevel gear. A threaded plate is threaded onto the surface of the lead screw. Insert rods are fixedly installed on the outer side of the threaded plate. The mounting plate is located on the front and rear sides of the two precast beams. Four reinforcing members are located on the left and right sides of the bottom of the two precast beams.
[0010] More preferably, the dimensions of the four lead screws are all the same, and the thread pitch on the surfaces of the four lead screws is the same.
[0011] More preferably, the surfaces of both mounting plates are threaded with first fixing bolts, the inner sides of the first fixing bolts are threaded to the inner surfaces of the two precast beams, and the surfaces of the four reinforcing members are threaded with second mounting bolts, the inner sides of the second mounting bolts are threaded to the inner surfaces of the two precast beams and the three precast columns.
[0012] More preferably, the surfaces of both knobs are threaded with limit bolts, and the top of the limit bolts is threaded to the inner surface of the precast beam.
[0013] More preferably, limiting grooves are provided on both the front and rear sides of the two first cavities, and the front and rear sides of the four threaded plates are slidably connected to the inner cavities of the eight limiting grooves.

[0016] More preferably, a locking block is fixedly installed on both the front and rear sides of the inner cavity of the second cavity, and the locking block is engaged in the inner cavity of the locking groove.
[0017] The present invention has the following advantages due to the adoption of the above technical solution:
[0018] I. This utility model, by setting up a connecting component, allows the threaded plate to move the insertion rod outward by rotating the knob, thereby connecting the precast beam and the precast column. The first fixing bolt and the reinforcing member further fix the precast column and the precast beam to each other, ensuring the firmness and stability of the precast beam and the precast column. Compared with the traditional method of using multiple bolts or welding, this method improves the convenience of connecting the precast beam and the precast column and makes it easier for operators to use.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0031] Example 1
[0032] like Figure 1-6 As shown, this utility model embodiment provides a high-strength precast beam-column connection structure, including:
[0033] The beam-column assembly 1 includes a precast beam 101 and a precast column 102. The precast column 102 is located at the bottom of the precast beam 101. The top of the precast column 102 is provided with a slot 104. The left and right sides of the precast column 102 are provided with insertion holes 103. The inner surface of the precast beam 101 is provided with a first cavity 105. The bottom left and right sides of the precast beam 101 are provided with a second cavity 106.
[0034] Connection component 2 includes knobs 201, mounting plates 207, and reinforcing members 209. Two knobs 201 are movably connected to the bottom of two precast beams 101. A driving bevel gear 202 is fixedly connected to the top of each knob 201. Driven bevel gears 203 are movably connected to the left and right sides of the inner cavity of the first cavity 105. The surface of the driving bevel gear 202 meshes with the surface of the driven bevel gear 203. A lead screw 204 is fixedly connected to the outer side of the driven bevel gear 203. A threaded plate 205 is threaded onto the surface of the lead screw 204. Insert rods 206 are fixedly installed on the outer side of the threaded plate 205. The mounting plate... 207 is located on the front and rear sides of the two precast beams 101. The four reinforcing members 209 are located on the left and right sides of the bottom of the two precast beams 101. The four lead screws 204 are all the same size and the thread pitch on the surface of the four lead screws 204 is the same. The surfaces of the two mounting plates 207 are threaded with first fixing bolts 208. The inner side of the first fixing bolts 208 is threaded to the inner surface of the two precast beams 101. The surfaces of the four reinforcing members 209 are threaded with second mounting bolts 210. The inner side of the second mounting bolts 210 is threaded to the inner surface of the two precast beams 101 and the three precast columns 102.
[0035] By setting the connecting component 2 and rotating the knob 201, the threaded plate 205 drives the insertion rod 206 to move outward, thereby connecting the precast beam 101 and the precast column 102. The first fixing bolt 208 and the reinforcing member 209 further fix the precast column 102 and the precast beam 101 to each other, ensuring the firmness and stability of the fixation of the precast beam 101 and the precast column 102. Compared with the traditional method of using multiple bolts or welding, this method improves the convenience of connecting the precast beam 101 and the precast column 102 to each other, making it easier for operators to use.
[0036] Example 2
[0037] like Figure 2-6 As shown, in one embodiment, the surfaces of the two knobs 201 are threaded with limit bolts 211, the top of the limit bolts 211 is threaded to the inner surface of the precast beam 101, the front and rear sides of the inner cavities of the two first cavities 105 are provided with limit grooves 212, the front and rear sides of the four threaded plates 205 are slidably connected to the inner cavities of the eight limit grooves 212, the left and right sides of the inner cavities of the first cavities 105 are provided with slots 213, the insertion rod 206 passes through the inner cavity of the slot 213 and is inserted into the inner cavity of the insertion hole 103, the inner cavity of the slot 213 and the inner cavity of the insertion hole 103 are both in the same horizontal direction, and the inner cavity of the slot 213 and the inner cavity of the insertion hole 103 are interconnected, the front and rear sides of the inner cavity of the second cavity 106 are fixedly installed with locking blocks 214, and the locking blocks 214 are locked into the inner cavity of the locking groove 104.
[0038] By setting the limiting bolt 211, the knob 201 can be limited to prevent it from rotating after long-term use. By setting the limiting groove 212, the movement of the threaded plate 205 can be limited to prevent the threaded plate 205 from deviating during movement, which would affect the connection between the precast beam 101 and the precast column 102. By setting the slot 213, the movement of the insertion rod 206 can be limited to prevent it from deviating during movement, which would affect the connection between the precast beam 101 and the precast column 102. By setting the locking block 214, the precast column 102 can be guided so that the inner cavities of the insertion hole 103 and the slot 213 are in the same horizontal direction.
[0039] In operation, the present invention firstly engages the precast column 102 into the inner cavity of the second cavity 106 through the cooperation of the slot 104 and the locking block 214. Then, by rotating the knob 201, the active bevel gear 202 rotates synchronously with the knob 201. The active bevel gear 202 and the driven bevel gear 203 cooperate with each other, so that the driven bevel gear 203 drives the lead screw 204 to rotate synchronously. The threaded plate 205 moves outward along the surface of the lead screw 204, and the threaded plate 205 drives the insertion rod 206 to move outward synchronously, so that the insertion rod 206 is inserted into the inner cavity of the insertion hole 103. Then, the mounting plate 207 is threadedly connected to the front and rear sides of the two precast beams 101 by the first fixing bolt 208. At the same time, the reinforcing member 209 is fixed to the surface of the precast column 102 and the precast beam 101 by the second mounting bolt 210, thus completing the connection between the precast beam 101 and the precast column 102.
