Description

Technical Field

[0001] This utility model belongs to the field of precast concrete components, specifically relating to a precast component for connecting joints in assembled concrete structures. Background Technology

[0002] Currently, the prefabricated concrete frame structures widely promoted and constructed in my country are mainly prefabricated monolithic concrete frames connected by overlapping cast-in-place methods. The main components include prefabricated beams, prefabricated columns, prefabricated exterior wall panels, prefabricated interior wall partitions, prefabricated floor slabs, prefabricated balcony slabs, prefabricated air conditioning slabs, and prefabricated stairs. The connection between prefabricated columns is often achieved by grouting sleeve connection. The grouting sleeve is embedded in the bottom of the upper prefabricated column, and the reinforcing bars of the lower prefabricated column extend above the cast-in-place floor slab. The reserved length ensures the anchorage length of the reinforcing bars in the grouting sleeve plus the width of the prefabricated column connection.

[0003] In existing construction operations, precast components are often connected by grouting. However, this method results in the grout adhering to the outside of the reinforcing bars, which limits the grout adhesion area and poses safety hazards during the use of precast components. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated component for connecting nodes in assembled concrete structures, which allows grouting to be directly applied inside the prefabricated component and the connector, thus forming a whole structure and improving the reliability of the overall frame structure.

[0005] To achieve the above objectives, this utility model provides a prefabricated component for connecting joints in prefabricated concrete structures, including a base, a connecting frame, and a prefabricated column. The connecting frame is horizontally arranged at the upper end of the base, and the prefabricated column is fixedly arranged at the upper end of the connecting frame.

[0006] The base has a vertical first docking groove, and the precast column has a vertical second docking groove.

[0007] The upper and lower surfaces of the connecting frame are provided with docking components, which are fitted into the first docking groove and the second docking groove.

[0008] Furthermore, the connecting frame has a horizontal main channel, and the main channel has first grouting holes at both its left and right ends, which connect the main channel to the outside.

[0009] Furthermore, the docking assembly includes a first reinforcing pipe and a second reinforcing pipe, wherein the first reinforcing pipe is vertically disposed at the lower end of the connecting frame, and the second reinforcing pipe is vertically disposed at the upper end of the connecting frame;

[0010] An auxiliary flow channel is provided in the center of the first reinforcing steel pipe. The head end of the auxiliary flow channel is connected to the main flow channel, and the tail end of the auxiliary flow channel is provided with an outlet hole.

[0011] The second reinforcing pipe has the same structure as the first reinforcing pipe. The tail end of the auxiliary flow channel of the first reinforcing pipe extends into the first docking groove, and the tail end of the auxiliary flow channel of the second reinforcing pipe extends into the second docking groove.

[0012] Furthermore, the first reinforcing pipe and the second reinforcing pipe are equidistant from each other along the length of the connecting frame.

[0013] Furthermore, the base and the precast column are both provided with second grouting holes at their left and right ends. One end of the second grouting hole is connected to the second docking groove, and the other end is connected to the outside.

[0014] Furthermore, a vertical guide hole is provided at the center of the precast column;

[0015] A central tube is fixedly installed at the center of the upper end face of the connecting frame. A through reserved opening is opened inside the central tube. A guide tube is fixedly installed on the outside of the central tube. A central flow channel is provided inside the guide tube.

[0016] The central tube is threadedly connected to the guide tube.

[0017] Furthermore, an adjustment platform is fixedly provided on the outer wall of the connecting frame, and an adjustment hole is provided inside the adjustment platform. An adjustment bolt is sleeved inside the adjustment hole, and an internal hexagonal nut is fixedly provided at the top of the adjustment bolt.

[0018] Furthermore, several adjustment platforms are fixedly arranged around the connecting frame, and the adjustment platforms are symmetrically distributed with the connecting frame as the center.

[0019] This utility model provides a prefabricated component for connecting joints in prefabricated concrete structures. It changes the previous method where grout adhered to the outside of the reinforcing bars. Through a slotted design, the connecting frame and the prefabricated column are installed from the inside, and flow channels are opened in the internal structure to allow the grout to flow inside the prefabricated column and the connecting frame and fill the entire structure, thus completing the production of the prefabricated component. Compared with the previous method, the prefabricated components have higher integrity, improve overall reliability, and reduce safety hazards.

[0030] Example 1

[0031] This embodiment provides, for example Figures 1-4 The prefabricated component for connecting nodes of a precast concrete structure shown includes a base 1, a connecting frame 2 and a precast column 3. The connecting frame 2 is horizontally arranged on the upper end of the base 1, and the precast column 3 is fixedly arranged on the upper end of the connecting frame 2. The connecting frame 2 serves as a connecting structure between the base 1 and the precast column 3, connecting the base 1 and the precast column 3 into a whole.

[0032] A vertical first docking groove 11 is opened on the base 1, and a vertical second docking groove 31 is opened on the precast column 3. The first docking groove 11 and the second docking groove 31 serve as the installation structure of the connecting frame 2 and are used to dock and install with the connecting frame 2.

[0033] The upper and lower ends of the connecting frame 2 are welded with docking components 4. The docking components 4 are fitted into the first docking groove 11 on the base 1 and the second docking groove 31 on the precast column, and finally connect the connecting component 2 with the base 1 and the precast column 3 to form an integral structure.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, a horizontal main channel 21 is provided inside the connecting frame 2. The main channel 21 serves as the main flow channel for the slurry to flow in the frame structure. The slurry flows from the main channel 21 to the base 1 and the precast column 3. A first grouting hole 22 is provided at both the left and right ends of the main channel 21. The first grouting hole 22 connects the main channel 21 to the outside world, and the slurry can be injected into the main channel 21 through the first grouting hole 22.

[0035] Furthermore, such as Figure 1 As shown, the docking assembly 4 includes a first reinforcing pipe 41 and a second reinforcing pipe 42. The first reinforcing pipe 41 is vertically installed at the lower end of the connecting frame 2, and the second reinforcing pipe 42 is vertically installed at the upper end of the connecting frame 2. That is, the first reinforcing pipe 41 and the second reinforcing pipe 42 are arranged opposite to each other. The first reinforcing pipe 41 is fitted into the first docking groove 11, and the second reinforcing pipe 42 is fitted into the second docking groove 31. By adding the docking assembly 4 to the connecting frame 2, the connecting frame 2 can better form an integral whole with the base 1 and the precast column 3.

[0036] An auxiliary flow channel 43 is provided in the center of the first steel pipe 41. The head end of the auxiliary flow channel 43 is connected to the main flow channel 21, and the tail end of the auxiliary flow channel 43 is provided with an outlet hole 44.

[0037] The second reinforcing pipe 42 has the same structure as the first reinforcing pipe 41. The tail end of the auxiliary flow channel 43 of the first reinforcing pipe 41 extends into the first docking groove 11, and the tail end of the auxiliary flow channel 43 of the second reinforcing pipe 42 extends into the second docking groove 31.

[0038] Since the main channel 21 is connected to the auxiliary channel 43, the slurry in the main channel 21 can flow into the auxiliary channel 43 and then flow out through the outlet hole 44 at the tail end to fill the first docking groove 11 and the second docking groove 31. This changes the previous form of slurry adhering to the outside and further increases the connection area between the connecting frame 2, the base 1, and the precast column 3, greatly increasing the reliability and stability of the structure.

[0039] Furthermore, the first reinforcing pipe 41 and the second reinforcing pipe 42 are equidistantly arranged along the length of the connecting frame 2. At equal intervals, the first reinforcing pipe 41 and the second reinforcing pipe 42 are evenly installed on the connecting frame 2, so that the grout can be distributed more evenly and the connection between the connecting frame 2 and the base 1 and the precast column 3 is more reliable.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, second grouting holes 5 are horizontally opened at both the left and right ends of the base 1 and the precast column 3. One end of the second grouting hole 5 is connected to the second docking groove 31, and the other end is connected to the outside. By opening additional grouting holes, namely second grouting holes 5, grouting holes 5 can simultaneously assist in grouting when grouting is performed from the first grouting hole 22, thereby speeding up the grouting speed and thus speeding up the molding efficiency of the precast component.

[0041] Furthermore, such as Figure 1 and Figure 3 As shown, a vertical guide hole 32 is provided in the center of the precast column 3. The guide hole 32 is located at the lower end of the precast column 3 and is used to position the precast column 3 during the installation of the connecting frame 2 to assist the precast column 3 and the connecting frame 2 in docking and installation.

[0042] A central tube 6 is fixedly welded at the center of the upper end face of the connecting frame 2. A through reserved opening 61 is opened inside the central tube 6. A guide tube 7 is fixedly installed on the outside of the central tube 6. A central flow channel 71 is set inside the guide tube 7. When the slurry flows to the center, it can flow through the reserved opening 61 of the central tube 6 into the guide tube 7, and then finally fill the guide hole 32 through the central flow channel 71.

[0043] Specifically, the central tube 6 and the guide tube 7 can be connected by threads. Then, the guide hole 32 of the precast column 3 is aligned with the guide tube 7 to complete the installation of the precast column 3.

[0044] Furthermore, such as Figure 1 and Figure 4As shown, an adjusting platform 8 is fixedly installed on the outer wall of the connecting frame 2. The adjusting platform 8 has a leveling hole 81 inside. A leveling bolt 82 is sleeved inside the leveling hole 81. An internal hexagonal nut 83 is fixedly installed at the top of the leveling bolt 82. By adjusting the internal hexagonal nut 83, the leveling bolt 82 is adjusted to rotate in the leveling hole 81, thereby changing the relative length of the leveling bolt 82 between the connecting frame 2 and the base 1, thereby changing the distance between the connecting frame 2 and the base 1, that is, the connecting frame 2 is relatively leveled. By leveling the surrounding adjusting platforms 8, the connecting frame 2 maintains a relatively horizontal accuracy relative to the base 1.

[0045] Furthermore, several adjustment platforms 8 are fixedly installed around the connecting frame 2, and the adjustment platforms 8 are symmetrically distributed with the connecting frame 2 as the center. The symmetrical installation of the adjustment platforms 8 improves the horizontal accuracy of the connecting frame 2, thereby further ensuring the structural accuracy and reliability of the entire prefabricated component after the connecting frame 2 is installed.

[0046] In use: First, insert the first steel rebar 41 at the bottom of the connecting frame 2 into the first mating groove 11 at the top of the base 1. Then, place the connecting frame 2 entirely on the base 1. Next, level the connecting frame 2 by rotating the leveling bolts 82 around the connecting frame 2. The movement of the leveling bolts 82 will help to level the horizontal accuracy of the connecting frame 2. Then, lift the precast column 3 and align the guide hole 32 at the lower end of the precast column 3 with the guide pipe 7 at the center of the connecting frame 2. This will guide the center position of the precast column 3 and assist the second mating groove 31 at the lower end of the precast column 3 to align with the second steel rebar at the top of the connecting frame 2. 42. After the precast column 3 and the connecting frame 2 are connected, grout can be injected into the first steel pipe 41 and the second connecting groove 31 to fix the connection. Then, grout can be injected into the main channel 21 through the second grouting hole 5. The grout can flow into the inner side of the first connecting groove 11 and the second connecting groove 31 through the main channel 21, the first flow channel and the second flow channel respectively, to further reinforce the connection from the inside. Some grout flows into the inner side of the guide hole 32 through the reserved port 61 and the auxiliary flow channel 43 to reinforce the center position. After the grout solidifies, the overall installation operation can be completed.

[0047] The internal splicing method greatly improves the integrity of the precast components and provides more grout bonding area. The solidified grout provides more reliable structural stability, resulting in higher formability of the precast components and safer use.

[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
