[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-5 The present invention provides a prefabricated cement load-bearing column structure, including a base plate 1, a protective sleeve 4, and multiple steel bar bodies 7, wherein the multiple steel bar bodies 7 are fixed by a positioning frame 8.
[0026] The upper end of the base plate 1 is provided with a base 2, the base 2 is provided with a bottom groove 3, the bottom of the bottom groove 3 is provided with multiple grooves, and the bottom ends of multiple steel bar bodies 7 are inserted into the designated grooves.
[0027] The protective sleeve 4 is located above the base 2. The base 2 has positioning holes 6 at its four corners. The lower end of the protective sleeve 4 has multiple positioning blocks 5 that are inserted into the positioning holes 6.
[0028] The steel bar body 7 is welded and fixed to the positioning frame 8.
[0029] Reinforcing bar positioning and initial fixing: Multiple reinforcing bar bodies 7 are fixed by positioning frames 8. The reinforcing bar bodies 7 and positioning frames 8 are firmly connected by welding to form a stable reinforcing bar skeleton. This connection method ensures that the reinforcing bars will not shift during subsequent operations, maintaining the accuracy of their relative positions.
[0030] Base 2 Installation and Rebar Positioning: Place the base plate 1 in the predetermined position. The base 2 is installed on the base plate 1. The base 2 has a bottom groove 3 inside. Multiple grooves at the bottom of the bottom groove 3 are used to accommodate the bottom end of the rebar body 7. Place the fixed rebar cage on the base 2 so that the bottom end of the rebar body 7 is inserted into the corresponding groove, thereby achieving the initial positioning of the rebar on the base 2.
[0031] Installation of Protective Sleeve 4: The protective sleeve 4 is located above the base 2. The positioning holes 6 at the four corners of the base 2 cooperate with the positioning blocks 5 at the lower end of the protective sleeve 4. During installation, the positioning blocks 5 of the protective sleeve 4 are aligned with the positioning holes 6 of the base 2 and inserted. This cooperation allows for quick and accurate installation of the protective sleeve 4 on the base 2, while also providing further positioning for the steel reinforcement cage.
[0032] Protective cover 4 reinforcement:
[0033] The base 2 has multiple support frames 9 on its periphery for limiting the position of the protective sleeve 4. The outer wall of the base 2 and the protective sleeve 4 is provided with a limiting groove 12. The inner side of the support frame 9 is provided with a limiting block 11 that is inserted into the limiting groove 12 and slidably connected with the limiting groove 12. The limiting groove 12 has a T-shaped cross section. The bottom end of the support frame 9 is provided with a positioning plate 10. The positioning plate 10 is fixed to the upper end of the base plate 1 by screws.
[0034] Support frames 9 are installed around the base 2, and positioning plates 10 at the bottom of the support frames 9 are fixed to the base plate 1 with screws. Limiting blocks 11 on the inner side of the support frames 9 are slidably connected to the T-shaped limiting grooves 12 on the outer wall of the base 2 and the protective sleeve 4. After the protective sleeve 4 is installed in place, the support frames 9 are slid along the limiting grooves 12, causing the limiting blocks 11 to embed into the limiting grooves 12, thereby limiting and reinforcing the protective sleeve 4, ensuring that the protective sleeve 4 remains stable during concrete pouring and does not shake or shift.
[0035] Concrete pouring: After completing the positioning of the reinforcing bars, installation and reinforcement of the protective sleeve 4, concrete is poured into the space formed by the protective sleeve 4 and the base 2. The concrete fills the space around the reinforcing bar skeleton, and after it solidifies, it forms a sturdy prefabricated cement load-bearing column together with the reinforcing bars to bear the vertical load of the building structure.
[0036] Easy to install and operate: The connection between each component is simple and clear, such as the cooperation between positioning block 5 and positioning hole 6, and the sliding connection between limiting block 11 and limiting groove 12. The operation is convenient, reducing the difficulty of construction. Even ordinary construction workers can quickly master the installation skills and improve the installation efficiency.
[0037] Enhanced structural stability: The welded and fixed steel reinforcement frame, the securely installed protective sleeve 4, and the support frame 9 make the prefabricated cement load-bearing column more structurally stable, better able to withstand the vertical load of the building, and improve the safety of the building structure.
[0038] 7. Reinforcing bar body: The appropriate specifications can be selected according to the load-bearing requirements. Common models include HRB400, and the diameter can be selected as 12mm, 14mm, 16mm, etc. The specific design load of the load-bearing column is determined to meet the structural strength requirements.
[0039] Positioning frame 8: The material can be Q235 steel, the thickness is determined according to the number of steel bars and the load-bearing requirements, and the size is customized according to the size of the steel bar cage to ensure that the steel bar body 7 can be firmly fixed.
[0040] Base plate 1: The material is C30 concrete. The dimensions are determined according to the load-bearing area and stability requirements at the bottom of the load-bearing column. The length and width can be customized according to the actual situation to ensure that it can provide a stable support foundation for the entire load-bearing column structure.
[0041] Base 2: The material is also C30 concrete. The depth of the bottom groove 3 is determined according to the insertion length of the steel bar. The groove size is adapted to the diameter of the steel bar body 7 to ensure that the steel bar can be inserted tightly. The diameter of the positioning hole 6 is 2-3mm larger than the diameter of the positioning block 5 to facilitate installation.
[0042] Protective sleeve 4: Made of C30 concrete, its size is determined according to the design size of the load-bearing column. The size of the positioning block 5 matches the positioning hole 6 to ensure that it can be smoothly inserted into the positioning hole 6 and provide a certain fastening force.
[0043] Support frame 9: The material is Q235 steel. The size of the limiting block 11 is adapted to the T-shaped limiting groove 12 to ensure smooth sliding in the limiting groove 12 and provide a reliable limiting effect. The size of the positioning plate 10 is determined according to the stress of the support frame 9.
