[0002] Reinforced concrete plate-type components processed in prefabrication plants (yards) or construction sites for building assembly are referred to as wall panels or sidings. According to the traditional method, the installation of prefabricated concrete walls must first be prepared before installation, including confirming the lifting plan, setting up safety protection measures, measuring the position and size of the wall, and installing the steel skeleton before the wall is installed. The steel bars need to be cut and welded according to the design requirements of the wall to make a suitable steel skeleton. Then the steel skeleton is placed at the installation position of the wall, and the steel skeleton is fixed to the wall with a steel welding machine. Before the wall is installed, the wall needs to be placed at the installation position. It is necessary to use a lifting machine to lift the wall, place the wall at the installation position according to the lifting plan, and then fix the wall to the steel skeleton with a hook.

[0003] After the wall is installed, it needs to be fixed. Usually, expansion bolts are used to fix the wall to the steel frame to ensure the safety and stability of the wall. This method is relatively cumbersome in construction technology and will consume more labor costs and material costs. Moreover, only using expansion bolts for fixing has limited fixing effect and may not achieve the expected stable enough effect. Summary of the invention

Usually, the wall is fixed to the steel frame using expansion bolts to ensure the safety and stability of the wall. This method is relatively complicated in construction technology and will consume more labor costs and material costs.

[0030] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 6 The embodiment of the present invention provides a precast concrete wall fixing structure, including a precast wall panel body 1, a beam slab 2 and a ground beam slab 6. A tube plate clamp 3 is installed on the top of the precast wall panel body 1, and the tube plate clamp 3 is connected to the bottom of the beam slab 2 through nails 4. A tube plate clamp 3 is installed on the bottom of the precast wall panel body 1, and the tube plate clamp 3 is connected to the ground beam slab 6. The tube plate clamp 3 and the nails 4 at the top of the precast wall panel body 1 cooperate with the tube plate clamp 3 at the bottom to position and quickly fix to the beam slab 2 and the ground beam slab 6 during installation. The tube clamp installation is convenient and efficient, and the nails 4 are firmly connected, which simplifies the construction process, reduces the time and difficulty of manual operation, reduces material loss, speeds up the construction speed, shortens the construction period, and ensures that the wall is tightly and firmly connected to the beam slab 2 and the ground beam slab 6, effectively enhancing the overall stability and safety of the wall, and improving the quality and reliability of the building structure.

[0032] See also Figure 1-Figure 2 The adjacent sides of the two prefabricated wall panel bodies 1 are respectively provided with a splicing groove 101 and a splicing groove 2 102. The splicing groove 101 and the splicing groove 2 102 of the prefabricated wall panel body 1 are connected by an adhesive material to ensure the integrity and sealing of the wall. The splicing groove 101 and the splicing groove 2 102 of the prefabricated wall panel body 1 are matched with the adhesive material. When the two wall panels are assembled, the grooves are butt-jointed and filled with the adhesive material, so that the adhesive fills the board seams evenly and is densely bonded, thereby enhancing the integrity of the wall, effectively preventing wall cracking, improving the waterproof, sound insulation and other sealing properties of the wall, reducing air and moisture penetration, ensuring a stable and comfortable indoor environment, improving the durability and structural reliability of the wall, and reducing the cost and frequency of later maintenance. The adhesive material can be a repair mortar for bonding.

[0033] See also Figure 1 and Figure 4In the connection between the prefabricated wall panel body 1 and the ground beam 6, the wooden wedge pad 5 is located between the tube plate clamp 3 and the ground beam 6, and is used to adjust the verticality and horizontality of the wall panel. Through the wooden wedge pad 5, in cooperation with the tube plate clamp 3 and the ground beam 6, when the prefabricated wall panel body 1 is installed, the wooden wedge pad 5 flexibly adjusts the thickness and position according to actual conditions, and the tube plate clamp 3 provides a stable connection foundation. The synergistic effect of the two realizes the adjustment of the verticality and horizontality of the prefabricated wall panel body 1, effectively reducing the inclination and unevenness of the wall caused by installation errors, improving the quality and accuracy of wall installation, ensuring that the wall surface is flat and beautiful, providing a good foundation for subsequent wall decoration and other construction, and improving the overall construction efficiency and quality stability.

[0034] See also Figure 5 The prefabricated wall panel body 1 is connected at the T-shaped connection part by the tube plate clamp 3 and the pin 7. The prefabricated wall panel body 1 is connected at the T-shaped connection part by the adhesive material to enhance the structural strength of the T-shaped part. The tube plate clamp 3 and the pin 7 cooperate with the adhesive material. After the tube plate clamp 3 is fixed to the wall at the T-shaped connection part, the connection is strengthened by the pin 7. The adhesive material fills the gap, which significantly enhances the shear, tensile and torsion resistance of the T-shaped part, effectively disperses the stress, avoids the structural damage caused by stress concentration, improves the overall structural stability, and makes the wall still stable under complex stress environment, reduces the safety hazards caused by structural weaknesses, and prolongs the service life of the building. The adhesive material can be a repair mortar for bonding.

[0035] See also Figure 6 The prefabricated wall panel body 1 is connected at the corner by the tube plate clamp 3 and the pin 7. The prefabricated wall panel body 1 is connected at the corner by the adhesive material to ensure the stability of the corner. The tube plate clamp 3 and the pin 7 cooperate with the adhesive material. The tube plate clamp 3 is tightly attached to the wall at the corner and deeply reinforced with the help of the pin 7. The adhesive material is seamlessly bonded, which greatly improves the deformation resistance and impact resistance of the corner, effectively maintains the geometric shape stability of the wall corner, prevents cracking and dislocation caused by external force or structural deformation, ensures the integrity and reliability of the overall building structure, and enhances the building's defense performance in natural disasters such as earthquakes and strong winds. The adhesive material can be bonded with repair mortar.

[0036] See also Figure 1 and Figure 3The reserved plate seam of the prefabricated wall panel body 1 is connected to the beam slab 2 by an adhesive material, which is used for the stability of the connection between the prefabricated wall panel body 1 and the beam slab 2. The reserved plate seam of the prefabricated wall panel body 1 is connected to the beam slab 2 by an adhesive material. The adhesive material fully fills the plate seam between the reserved plate seam of the prefabricated wall panel body 1 and the beam slab 2, and is tightly attached to the wall panel body and the beam slab 2. The two are firmly connected as one by strong bonding, which effectively ensures the stability of the connection. The stability of the connection between the prefabricated wall panel body 1 and the beam slab 2 is strengthened, the load is effectively transferred and dispersed, the structural deformation and cracks caused by weak connection are reduced, the overall structure's coordinated force bearing capacity is improved, the reliability and safety of the building structure are enhanced, and the stability and durability of the building during use are ensured. The adhesive material can be a repair mortar for bonding.

[0037] See also Figure 3-Figure 6 The tube plate clamp 3 is made of high-strength steel and is treated with anti-corrosion. The tube plate clamp 3 made of high-strength steel and treated with anti-corrosion is matched with the prefabricated wall panel body 1 and the related connection structure. The tube plate clamp 3 is firmly anchored in the key part of the wall by virtue of its high strength characteristics, and can reliably bear and transfer stress under various complex stress conditions. The anti-corrosion treatment enables it to resist corrosion factors such as water vapor, acid and alkali in the environment, and realizes long-term and stable reliable connection support for the wall, effectively extending the service life of the tube plate clamp 3, reducing the structural performance degradation caused by material aging and rust, ensuring the durability and safety of the wall fixed structure, and reducing the maintenance cost and frequency in the whole life cycle of the building.

[0038] See also Figure 1-Figure 6 The present invention also provides a method for fixing a precast concrete wall, comprising the following steps:

[0039] S1, upper end connection, at the upper end of each prefabricated wall panel body 1, 75mm to 85mm away from the wall panel edge, install only the tube plate clamp 3 in the middle of the plate thickness, tap the tube plate clamp 3 into the plate by not less than 75mm to 85mm and place it vertically, and fix the tube plate clamp 3 at the upper end of the prefabricated wall panel body 1 to the beam plate 2 surface with nails 4;

[0040] S2. Connect the lower end. Install the tube plate clamp 3 at the lower end of each prefabricated wall panel body 1, about 75mm to 85mm away from the edge of the wall panel, in the middle of the board thickness. Tap the tube plate clamp into the prefabricated wall panel body 1 by no less than 75mm to 85mm and place it vertically. Pad the lower end of the prefabricated wall panel body 1 with a wooden wedge block 5 to temporarily fix it, leaving a gap of 15-20mm. Smear the special wall panel repair mortar to bond it. Use a plumb line and a ruler to hang the verticality or use an infrared projection meter to check the straightness. Tap the upper and lower wooden wedge blocks 5 to adjust them and fix them to the ground beam 6.

[0041] The tube plate card 1 3 is installed and deeply embedded at a specific position on the upper end of the prefabricated wall panel body 1, and then the tube plate card 2 5 is vertically embedded at a suitable position at the lower end of the prefabricated wall panel body 1 from the wall panel edge. By adjusting the position of the wooden wedge pad 6 and cooperating with the special wall panel repair mortar, the stability and reliability of the wall structure are jointly guaranteed. The tube plate card 3 is firmly embedded in the plate at the middle position of the plate thickness of 75mm to 85mm from the wall panel edge, not less than 75mm to 85mm, and maintains a vertical posture. The beam plate 2 is tightly connected by nails 4 to effectively transfer and disperse the upper load; the tube plate card 3 provides a stable support foundation for the wall at the corresponding position at the lower end. The wooden wedge pad 5 cleverly adjusts the height and angle according to the actual situation during the connection process at the lower end, so that the wall is initially positioned and a reasonable 15-20mm gap is reserved. The repair mortar is then evenly applied and filled, and the gap is sealed while bonding. Use a plumb bob and a ruler or an infrared line projection instrument to monitor and adjust, and fine-tune by knocking the wooden wedge pad 5. Such operation achieves high precision and strong stability in the connection between the upper and lower ends of the prefabricated wall panel body 1, greatly enhances the stability and bearing capacity of the overall wall structure, effectively resists various complex external forces such as earthquakes and wind, and significantly reduces the risks of wall deformation and cracking caused by weak connection parts, thereby ensuring the safety and reliability of the building structure during long-term use. In addition, during the construction process, it helps to standardize the operating procedures, improve construction efficiency, reduce the consumption of manpower and time costs, and improve the quality and benefits of the overall construction.

[0042] See also Figure 1-Figure 2 S10, the splicing groove 101 and the splicing groove 2 102 of the prefabricated wall panel body 1 are fully embedded with bonding mortar, and the amount of smearing is preferably such that the special wall panel repair mortar adhesive is evenly squeezed out of the assembled board seam;

[0043] S20. During installation, use a crowbar to lift the bottom end of the prefabricated wall panel body 1, slightly lift the prefabricated wall panel body 1 installed later and move it toward the adjacent prefabricated wall panel body 1 installed earlier, so that they are naturally put together and close together, so that the upper and lower ends of the prefabricated wall panel body 1 are dense and bonded with special repair mortar for the prefabricated wall panel body 1. The installation of the prefabricated wall panel body 1 is carried out sequentially from the structural column side to the other side.

[0044] By fully filling the splicing groove 101 and the splicing groove 2 102 with bonding mortar, in cooperation with the crowbar and the special repair mortar, the bonding mortar at the splicing groove fully fills the space in the groove when the two prefabricated wall panel bodies 1 are assembled. When the rear-installed wall panel is lifted up with the help of the crowbar and moves in the direction of the first-installed wall panel, the bonding mortar is evenly stressed and tightly bonded, so that the board seams are tight and the upper and lower ends are further compacted under the action of the special repair mortar. In this way, seamless docking and high-strength bonding between the prefabricated wall panel bodies 1 are achieved, the integrity and stability of the whole wall are enhanced, cracks and leakage problems caused by weak splicing are effectively prevented, the waterproof, sound insulation and other properties of the wall are improved, the comfort and safety of the interior space of the building are guaranteed, and at the same time, the splicing process in construction is simplified, the construction efficiency is improved, the rework and material waste caused by improper splicing are reduced, and the construction process and resource utilization are optimized.

[0045] See also Figure 5-Figure 6 S100, the method of fixing the connection of the T-shaped part of the precast concrete wall, using the tube plate clamp 3, the pin 7, the special repair mortar pin 7 materials and tools, installing the tube plate clamp 3 at the T-shaped part, knocking it into the wall, and then fixing it with nails 4, implanting the pin 7 at the upper and lower parts of the wall height to enhance the shear and tensile resistance, and filling the special repair mortar at the T-shaped connection part of the precast wall panel body 1;

[0046] S200. The high-strength tube plate clamp 3 for the corner is installed and knocked into the prefabricated wall panel body 1 and anchored with nails 4 to resist separation and dislocation. Pins 7 are implanted above and below the wall height to form a stable structure with the tube plate clamp 3 and nails 4 to improve torsion resistance and deformation resistance to ensure shape stability. The seams of the prefabricated wall panel body 1 at the corner are fully embedded with special repair mortar for compaction and bonding.

[0047] Through the cooperation of the tube plate clamp 3, nail 4, pin 7 and special repair mortar at the T-shaped part, and the tube plate clamp 3, nail 4, pin 7 and special repair mortar at the corner part, the tube plate clamp 3 at the T-shaped part is accurately knocked into the wall and then the nail 4 is fixed, and the pin 7 is implanted at a specific position of the wall height to enhance the shear and tensile resistance, and the special repair mortar fills the gap and bonds tightly; the tube plate clamp 3 at the corner is strongly knocked in and nailed 4 is anchored, and the pin 7 is scientifically implanted to form a stable system with the tube plate clamp 3 and nail 4. In this way, the excellent structural reinforcement of the T-shaped and corner parts of the precast concrete wall is achieved, which greatly improves the stability of the overall wall under complex stress environment, effectively resists shear force, tension, torque and deformation, prevents cracks, dislocation and other structural damages due to stress concentration at the T-shaped and corner parts, ensures the integrity and safety of the building structure, and extends the service life of the building. At the same time, it reduces the maintenance cost and repair frequency caused by local structural defects, improves the durability and reliability of the building, and optimizes the performance of the building.
