The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] An embodiment of the present utility model provides a wall connection device, as Figures 1-4 shown, the wall connection device includes: a precast wall 2 disposed on a bottom beam 1, a grouting groove 4 into which concrete slurry can be poured is disposed at the connection between the precast wall 2 and the bottom beam 1; a corrugated pipe 3 for grouting into the grouting groove 4, the corrugated pipe 3 is disposed in the precast wall 2, and the slurry outlet end of the corrugated pipe 3 is communicated with the grouting groove 4; a plurality of steel bars 5 for enhancing the connection strength, the steel bars 5 are preset on the bottom beam 1, and the top ends of the steel bars 5 extend into the grouting groove 4; a mortar bedding layer 6, the mortar bedding layer 6 is disposed at the connection between the precast wall 2 and the bottom beam 1; a reinforcement mechanism for reinforcing the precast wall 2 and the bottom beam 1, the reinforcement mechanism is disposed on the precast wall 2 and the bottom beam 1.
[0022] In this embodiment, the prefabricated wall 2 is produced in a factory and then transported to the site for installation. The connection with the bottom beam 1 is achieved through a grouting groove, which ensures the strength and sealing of the connection. The grouting groove 4 is arranged at the connection between the prefabricated wall 2 and the bottom beam 1. The grouting end of the corrugated pipe 3 is connected to the grouting groove 4. By pouring concrete slurry into the grouting groove 4, the gap between the connection between the prefabricated wall 2 and the bottom beam 1 can be filled to form a convex portion. The bonding strength between the prefabricated wall 2 and the bottom beam 1 is improved. The corrugated pipe 3 is used to guide the concrete slurry into the grouting groove 4, and ensure that the grouting process is smooth. In order to ensure the smooth progress of the process and improve the construction efficiency, the steel bar 5 is pre-set at the top of the bottom beam 1 and extends into the grouting groove 4, which is tightly combined with the concrete structure of the raised part formed after grouting to enhance the connection strength. The mortar layer 6 is arranged at the connection between the prefabricated wall 2 and the bottom beam 1. The mortar layer 6 is spread in advance and lifted to achieve a sealing effect, thereby sealing the grouting groove 4 and preventing the poured concrete slurry from flowing out of the gap between the prefabricated wall 2 and the bottom beam 1. The design of the reinforcement mechanism can improve the stability of the connection between the prefabricated wall 2 and the bottom beam 1, and the concrete with the raised part can be removed after solidification.
[0023] In a further preferred embodiment of the utility model, the reinforcement mechanism includes: a plurality of first angle codes 7 arranged on one side of the bottom beam 1; a plurality of second angle codes 8 symmetrically arranged on both sides of the prefabricated wall 2, and a positioning block 9 is fixed on the corresponding second angle code 8, and the bottom end of the positioning block 9 passes through the corresponding first angle code 7; a plurality of threaded tubes 10 preset in the prefabricated wall 2 and the bottom beam 1; and bolts 11 assembled on the corresponding first angle code 7 and the second angle code 8, and the bolts 11 are threadedly connected with the corresponding threaded tubes 10.
[0024] In this embodiment, a number of first corner blocks 7 are provided on one side of the bottom beam 1. These corner blocks serve as the basic part of the reinforcement mechanism and provide stable support points. At the same time, a number of second corner blocks 8 are symmetrically arranged on both sides of the precast wall 2. These corner blocks are closely combined with the precast wall 2 to jointly undertake the reinforcement task. Through the arrangement of the first corner blocks 7 and the second corner blocks 8, a double reinforcement network is formed at the connection between the precast wall 2 and the bottom beam 1. This structural design not only enhances the lateral stability of the connection but also improves the torsional resistance of the connection, effectively preventing deformation or displacement caused by external forces. The introduction of the positioning blocks 9: A positioning block 9 is fixed on each second corner block 8, and the bottom ends of these positioning blocks penetrate the corresponding first corner blocks 7. This design forms an accurate positioning relationship between the second corner block 8 and the first corner block 7, ensuring the installation accuracy and stability of the reinforcement mechanism. The introduction of the positioning blocks 9 simplifies the installation process of the reinforcement mechanism and improves the construction efficiency. At the same time, it can effectively prevent misalignment or deviation during the reinforcement process, ensuring the consistency and reliability of the reinforcement effect. A number of threaded cylinders 10 are preset in the precast wall 2 and the bottom beam 1. These threaded cylinders serve as the fixing points for the bolts 11. The bolts 11 are assembled on the corresponding first corner blocks 7 and second corner blocks 8 and are tightened through threaded connection with the threaded cylinders 10. The cooperation of the threaded cylinders 10 and the bolts 11 provides a reliable tightening force for the reinforcement mechanism. This design not only improves the strength and stability of the connection but also prevents the displacement of the precast wall 2 when grouting into the grouting groove 4, which is beneficial to safety.
[0025] In a further preferred embodiment of the present utility model, a support mechanism is provided on the second corner block 8. The support mechanism includes: a plug-in block 12 fixed on the second corner block 8, and a separable connection sleeve 13 is sleeved outside the plug-in block 12; a support rod 14 assembled on the connection sleeve 13 and capable of being disassembled, and a base plate 15 is fixedly installed at the bottom end of the support rod 14; positioning rods 16 symmetrically arranged on the base plate 15 and capable of being inserted into the soil layer for positioning; a pin rod 17 assembled on the connection sleeve 13, and the corresponding pin rod 17 penetrates through the plug-in block 12 and the support rod 14 for limiting.
[0026] In this embodiment, the reinforcement at the connection between the precast wall 2 and the bottom beam 1 is designed in a more detailed and comprehensive manner. The insertion block 12 is firmly fixed on the second angle code 8 and serves as the basic part of the support mechanism. The connecting sleeve 13 is detachably sleeved outside the insertion block 12, realizing the flexible connection between the support rod 14 and the second angle code 8. This design allows the support rod 14 to be disassembled and installed as needed, facilitating adjustment and transportation during the construction process. The support rod 14 is assembled on the connecting sleeve 13, and a base plate 15 is fixedly installed at its bottom end. The base plate 15, as the contact surface between the support mechanism and the ground, increases the support area and improves the stability of the support. The length and material of the support rod 14 can be selected according to actual needs to meet the requirements of different construction scenarios. The positioning rods 16 symmetrically arranged on the base plate 15 can be easily inserted into the soil layer for positioning. This design enables the support mechanism to be firmly fixed on the ground at the construction site, preventing movement or tipping due to external forces. At the same time, the positioning rods 16 also play a role in enhancing the overall stability of the support mechanism. The pin rod 17 assembled on the connecting sleeve 13 passes through the insertion block 12 and the support rod 14 for limiting. This design ensures the firm connection between the support rod 14 and the second angle code 8, preventing loosening or detachment due to vibration or impact during the construction process. The introduction of the support mechanism further enhances the reinforcement effect at the connection between the precast wall 2 and the bottom beam 1. Through the support of the support rod 14 and the base plate 15, the force at the connection is effectively dispersed, improving the stability and durability of the connection. The detachable design of the support rod 14 and the connecting sleeve 13 enables the support mechanism to be flexibly adjusted according to construction needs. For example, the support rod 14 can be disassembled during transportation to reduce the volume and weight. At the construction site, the appropriate length and material of the support rod 14 can be selected according to the terrain and soil conditions. The function of the positioning rods 16 inserted into the soil layer for positioning ensures the stability of the support mechanism during the construction process, preventing safety accidents caused by movement or tipping. At the same time, the limiting effect of the pin rod 17 also prevents the support rod 14 from loosening or detaching during the force application process, further enhancing the construction safety.
[0027] In a further preferred embodiment of the present utility model, a cushion block is fixedly installed at the top end of the positioning rod 16, and a through hole for upward lifting is formed in the cushion block.
[0028] In this embodiment, the cushion block is fixed at the top end of the positioning rod 16 and can play a limiting role when ramming the positioning rod 16. The through hole formed in the cushion block is designed to facilitate the construction workers to lift the positioning rod 16 upward. The construction workers can insert tools (such as crowbars) through this through hole to pull out the positioning rod 16 from the soil layer.
[0029] In a further preferred embodiment of the present utility model, a reinforcing block is fixedly installed on the positioning rod 16, and the bottom of the reinforcing block is fixedly connected to the base plate 15.
[0030] In this embodiment, the structure of the positioning rod 16 is enhanced. Specifically, a reinforcing block is fixedly installed on the positioning rod 16, and the bottom of this reinforcing block is fixedly connected to the base plate 15, enhancing the connection strength between the positioning rod 16 and the base plate 15.
[0031] In a further preferred embodiment of the present utility model, a plurality of assembly holes are symmetrically formed on the base plate 15. The assembly holes are adapted to the corresponding positioning rods 16, and the bottom end of the positioning rod 16 is conical.
[0032] In this embodiment, the positions and quantities of the assembly holes symmetrically formed on the base plate 15 are determined according to actual needs and the layout of the positioning rods 16. The bottom end of the positioning rod 16 is designed to be conical. This structure enables the positioning rod to more easily penetrate the soil when inserted into the soil layer, reducing the insertion resistance. At the same time, the conical structure can also increase the contact area between the positioning rod and the soil layer, improving the stability of the support.
[0033] In a further preferred embodiment of the present utility model, insertion holes are formed on both the positioning rod 16 and the insertion block 12, and the insertion holes are adapted to the corresponding pin rods 17.
[0034] In this embodiment, the insertion holes formed on the positioning rod 16 and the insertion block 12 ensure that the pin rod 17 can be smoothly inserted and play an effective limiting and fixing role.
[0035] In summary, the combination of the grouting groove 4 and the steel bar 5 enhances the bonding strength between the wall and the bottom beam. The mechanical fixation of the first angle code 7, the second angle code 8, the positioning block 9, the threaded barrel 10, and the bolt 11 in the reinforcement mechanism, as well as the support of the support rod 14 and the base plate 15 in the support mechanism, jointly improve the lateral stability, torsional resistance, and seismic performance of the connection part. The setting of the mortar layer 6 provides a sealing effect in advance, and in cooperation with the use of the grouting groove 4 and the corrugated pipe 3, it ensures the efficiency of the construction process and the sealing of the wall connection. The introduction of the support mechanism, especially the flexible connection between the support rod 14 and the second angle code 8 through the connecting sleeve 13, as well as the design of the positioning rod 16 and the pin rod 17, not only improves the adjustment convenience and transportation efficiency during the construction process, but also ensures the stability of the connection part.
