Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a prefabricated steel slag sand concrete frame structure. Background Technology

[0002] Concrete frame structures are one of the most common building structures. For example, patent application number CN202320630463.0 discloses a prefabricated steel slag sand concrete frame structure. This utility model includes composite beams and composite floor slabs. Several composite beams are arranged in a ring to form a frame structure; several composite floor slabs are horizontally embedded within the frame structure; the composite beams, from bottom to top, are successively provided with precast steel slag sand concrete beams and cast-in-place concrete layers, and the composite floor slabs, from bottom to top, are successively provided with precast steel slag sand concrete slabs and cast-in-place concrete layers. The composite beams, composite floor slabs, and precast columns of this utility model's frame structure use steel slag sand concrete, which replaces natural sand in the concrete, reducing the amount of natural sand mined and increasing the utilization rate and added value of steel slag. The steel slag sand concrete also possesses excellent mechanical properties.

[0003] In existing concrete frame structures, after the adjacent column members are assembled, grouting is required through grouting sleeves to connect and fix the steel bars of the two column members to enhance the connection strength between the column members. However, the existing grouting sleeves do not have an automatic sealing structure between the grouting channel and the grout outlet channel. This makes it easy for foreign objects to enter the grouting sleeves during the prefabrication and transportation of column members, reducing the connection strength between the column members. Furthermore, after the grouting pipe is pulled out after grouting, some grout is prone to leaking from the inside of the grouting sleeve, which also reduces the connection strength between the column members. The structure has poor stability and low practicality. Utility Model Content

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] As attached Figure 1 To be continued Figure 6 As shown:

[0024] Example 1: This utility model provides a prefabricated steel slag sand concrete frame structure, including column members 1 and grouting components 2; the column member 1 includes a concrete column 101, main reinforcement 102, and stirrups 103. The stirrups 103 are tied to the outside of the main reinforcement 102, and the main reinforcement 102 and stirrups 103 are placed in the column formwork and the concrete column 101 is formed by pouring concrete. The column member 1 is fixedly connected to the beam members and slab members through connection nodes; the grouting component 2 includes a grouting sleeve 2. 01 and the closing mechanism, the grouting sleeve 201 is fixedly installed on the outside of the main reinforcement 102, and the grouting sleeve 201 is located at the bottom of the concrete column 101, and the main reinforcement 102 exposed at the top of the concrete column 101 is inserted into the inside of the grouting sleeve 201 inside the adjacent concrete column 101 at its top. The closing mechanism includes a linkage rod 202 and a control block 203. The linkage rod 202 is rotatably connected to the inside of the grouting sleeve 201, and the control block 203 is inserted into the inside of the grouting sleeve 201.

[0025] In this embodiment, the bottom cross-section of the grouting sleeve 201 is trumpet-shaped, and a reinforcing connecting rod 2011 is provided on the outside of the grouting sleeve 201. This design facilitates the insertion of the main reinforcement 102 of the bottom column member 1 into the grouting sleeve 201 of the top column member 1, making the connection operation convenient. In addition, the reinforcing connecting rod 2011 can increase the contact area between the grouting sleeve 201 and the concrete column 101, ensuring that the grouting assembly 2 can be stably installed inside the concrete column 101, and is stable in use.

[0026] In this embodiment, the linkage rod 202 is provided with sealing balls 2021 at both the top and bottom, and the two sealing balls 2021 are respectively located inside the grout outlet channel 2012 at the top and the grouting channel 2013 at the bottom of the grouting sleeve 201. The bottom of the control block 203 is provided with a sealing top spring 2032, and the two ends of the sealing top spring 2032 abut against the bottom of the control block 203 and the inside of the grouting sleeve 201, respectively. The sealing ball 2021 is provided with a connecting channel 2211 inside. When the control block 203 is not pulled down by external force, the connecting channel 2211 is perpendicular to the channels of the grout outlet channel 2012 and the grouting channel 2013. In use, under the action of the sealing mechanism, when the grouting assembly 2 is in the reset state, the grout outlet channel 2... Both 012 and grouting channel 2013 are in a blocked state, which effectively avoids the phenomenon that foreign objects can easily enter the grouting sleeve 201 during prefabrication and transportation, and that grout leakage can occur due to failure to seal the channels in time after grouting. The grouting component 2 is in the reset state (the control block 203 is not pulled down by external force), under the action of the sealing top spring 2032, the connecting channel 2211 inside the two sealing plugs 2021 is perpendicular to the channels of the grout outlet channel 2012 and the grouting channel 2013. Thus, the two sealing plugs 2021 can block the channels of the grout outlet channel 2012 and the grouting channel 2013, realizing the function of automatically sealing the internal channels of the grouting sleeve 201, and the grouting component 2 is stable in use.

[0027] In this embodiment, the linkage rod 202 has a spiral-oriented control groove 2022 on its exterior, and the control block 203 has a control protrusion 2031 inside. The control protrusion 2031 is inserted into the control groove 2022. In use, when grout needs to be injected into the grouting sleeve 201, simply pull down the control block 203 to open the grout outlet channel 2012 and the grouting channel 2013. When the control block 203 is pulled down, it moves downward and compresses the sealing top spring 2032. When the control block 203 moves downward, the control protrusion 2031 can drive the linkage rod 202 to rotate through the control groove 2022. As the linkage rod 202 rotates, the sealing ball 2021 also rotates, thereby aligning the connecting channel 2211 inside the two sealing balls 2021 with the channels of the grout outlet channel 2012 and the grouting channel 2013, respectively, thus allowing the grout to flow through. After switching grouting channel 2012 and grouting channel 2013 to the open state, the grouting pipe of the grouting equipment is inserted into the grouting channel 2013 for grouting. After the grouting pipe is inserted into the grouting channel 2013 and the connecting channel 2211 of the sealing ball 2021 inside the grouting channel 2013, the grouting pipe will lock the sealing ball 2021, thus preventing the grouting component 2 from resetting, and the grouting operation can continue. When the grouting sleeve 201 is full of grout, the excess grout will flow out from the grout outlet channel 2012, thus reminding the construction personnel to stop the grouting operation. After that, the grouting pipe can be pulled out. After the grouting pipe is pulled out, under the action of the sealing top spring 2032, the grouting component 2 will automatically return to the reset state and re-seal the grout outlet channel 2012 and grouting channel 2013 to prevent grout leakage inside the grouting sleeve 201. The construction is stable and the use is convenient and flexible.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this utility model, the column member 1 is connected to the beam member and slab member through connection nodes, enabling the assembly construction of the concrete frame structure. Simultaneously, the column members 1 can also be installed and used in an assembled manner. The grouting assembly 2 ensures a stable connection between adjacent column members 1. Under the action of the sealing mechanism, when the grouting assembly 2 is in the reset state, both the grout outlet channel 2012 and the grouting channel 2013 are blocked. This effectively prevents foreign objects from easily entering the grouting sleeve 201 during prefabrication and transportation, and avoids grout leakage caused by unsealed channels after grouting. This ensures stable use, improves construction quality, and enhances the grouting assembly's effectiveness. When component 2 is in the reset state (control block 203 is not pulled downward by external force), under the action of the sealing top spring 2032, the connecting channel 2211 inside the two sealing plugs 2021 is perpendicular to the channels of the grout outlet channel 2012 and the grout injection channel 2013. Therefore, the two sealing plugs 2021 can block the channels of the grout outlet channel 2012 and the grout injection channel 2013, realizing the function of automatically sealing the internal channels of the grouting sleeve 201. When grout needs to be injected into the grouting sleeve 201, simply pull down the control block 203 to open the grout outlet channel 2012 and the grout injection channel 2013. When the control block 203 is pulled down... The control block 203 moves downward and compresses the sealing top spring 2032. As the control block 203 moves downward, the control protrusion 2031 drives the linkage rod 202 to rotate via the control groove 2022. When the linkage rod 202 rotates, the sealing ball 2021 also rotates, thus aligning the connecting channels 2211 inside the two sealing balls 2021 with the channels of the grout outlet channel 2012 and the grout injection channel 2013, respectively. This switches the grout outlet channel 2012 and the grout injection channel 2013 to the open state. Afterward, the grouting pipe of the grouting equipment can be inserted into the grout injection channel 2013 for grouting. After the grouting channel 2013 and the grouting tube 2021 are sealed inside the connecting channel 2211, the grouting pipe will be stuck in the sealing tube 2021, thus preventing the grouting component 2 from resetting and allowing the grouting operation to continue. When the grouting sleeve 201 is full of grout, the excess grout will flow out from the grout outlet channel 2012, thus reminding the construction personnel to stop the grouting operation. After that, the grouting pipe can be pulled out. After the grouting pipe is pulled out, under the action of the sealing top spring 2032, the grouting component 2 will automatically return to the reset state and reseal the grout outlet channel 2012 and the grouting channel 2013 to prevent the grout inside the grouting sleeve 201 from leaking.
