Description

Technical Field

[0001] The invention discloses an SPCS composite shear wall environmentally friendly construction structure, belonging to the technical field of prefabricated building construction. Background Art

[0002] The Prefabricated Composite Structure System (SPCS) is a prefabricated concrete structure in which all or part of the lateral force-resisting components are composite shear walls. Composite shear walls are prefabricated components consisting of a prefabricated steel cage flanked by precast wall panels, with a central cavity. After the composite shear wall components are installed on-site, concrete is poured into the cavity, integrating the cast-in-place concrete with the precast components to form a composite shear wall that can withstand both vertical and horizontal forces.

[0003] Conventional precast solid shear walls require grouting at the bottom of the wall and securing with sleeve grouting. However, after the SPCS composite shear wall components are installed on-site, concrete is poured into the cavity, connecting the cast-in-place concrete and precast components as a whole, forming a composite shear wall that jointly withstands vertical and horizontal forces. The bottom directly contacts the lower structure and is fixed as a whole with the cast-in-place concrete. SPCS precast walls are composed of multiple wall panels assembled to form a single shear wall, and the cast-in-place gaps at the bottom are prone to grout leakage and wall cracking. A Chinese invention patent with application number 202311222070.7, filed on September 21, 2023, and titled "A Standardized Formwork for Sealing the Bottom End of SPCS Precast Wall Components," discloses a technical solution that uses angle steel and bolts to fix the components, although this method solves the problems of cracking and grout leakage to a certain extent. However, due to poor ground flatness or inadequate wall reinforcement, grout leakage, cracking, and poor wall base appearance can still occur. Therefore, in order to avoid the problems of leakage, slurry running and wall cracking at the bottom of the SPCS composite shear wall structure during concrete pouring, an effective technical solution for reinforcing the SPCS composite shear wall and sealing the bottom gap is designed to speed up the construction progress, ensure the construction quality and reduce the construction cost, which has become an urgent problem to be solved in this field.

DETAILED DESCRIPTION

[0027] Figures 1 to 6This is the best embodiment of the present invention, Figures 1 to 6 The utility model is further described.

[0028] like Figures 1 and 2 As shown, an environmentally friendly SPCS composite shear wall structure includes two prefabricated walls 5 spaced apart from each other. Both prefabricated walls 5 are arranged vertically. Connecting steel bars 1 are located on the opposing inner sides of each prefabricated wall 5. Each connecting steel bar 1 on the inner side of each prefabricated wall 5 is a mesh structure composed of multiple horizontally arranged steel bars and multiple vertically arranged steel bars interlaced and fixed.

[0029] A timber assembly is arranged on the outer side of each prefabricated wall 5. This assembly includes multiple timbers 4 spaced apart in the middle of the prefabricated wall 5 and multiple timbers 4 at the ends of the prefabricated wall 5. The timbers 4 in the middle are spaced apart sequentially, while the timbers 4 at the ends are closely spaced. All timbers 4 are arranged vertically.

[0030] On the exterior side of each prefabricated wall 5, several groups of steel pipe assemblies are arranged perpendicular to the timbers 4. These groups are spaced apart along the height of the timbers 4. Each group of steel pipe assemblies includes two supporting steel pipes 3 arranged side by side. Multiple tensioning assemblies 2 are also positioned between the two supporting steel pipes 3 in each group of steel pipe assemblies. The multiple tensioning assemblies 2 corresponding to each group of steel pipe assemblies are sequentially positioned between the two supporting steel pipes 3 along the arrangement direction of the supporting steel pipes 3.

[0031] The tensioning components 2 are fixed after passing through the prefabricated walls 5 on both sides. By arranging multiple groups of tensioning components 2 along the vertical direction of the prefabricated walls 5, the supporting steel pipes 3 and the square timber components are fixed to the prefabricated walls 5 on the corresponding sides, and the casting space in the middle is formed.

[0032] A bottom blocking mechanism 6 is also provided at the bottom of the prefabricated walls 5 on both sides. The bottom blocking mechanism 6 is located between two closely arranged groups of square timbers 4 at the ends of the prefabricated walls 5. Figures 3 and 4 The bottom blocking mechanism 6 includes two blocking angle steels 8 arranged opposite to each other. The two blocking angle steels 8 are respectively located at the bottom of the two prefabricated walls 5, and the two ends of the two blocking angle steels 8 are respectively in contact with the square timbers 4 at both ends of the corresponding prefabricated walls 5.

[0033] The vertical surfaces of the two blocking angle steels 8 are aligned with the wall surfaces of the corresponding prefabricated walls 5, and the horizontal surfaces of the two blocking angle steels 8 are aligned with the ground. The two blocking angle steels 8 are simultaneously fixed by multiple tensioning assemblies 2 arranged in sequence along their lengths. A sealing gasket 10 is also provided at the bottom of the horizontal surface of each blocking angle steel 8.

[0034] The tensioning assembly 2 includes tensioning bolts 9. The tensioning bolts at the bottom blocking mechanism 6 penetrate both blocking angle steels 8 and the two precast walls 5. The tensioning bolts 9 at the steel pipe assembly penetrate the two precast walls 5 and then pass through the two supporting steel pipes 3. Pads 11 are also provided on either side of the tensioning bolts 9. The pads 11 at the bottom blocking mechanism 6 are located on the vertical surfaces of the two blocking angle steels 8. The tensioning bolts 9 at the steel pipe assembly penetrate the two precast walls 5 and then rest on the surfaces of the supporting steel pipes 3.

[0035] Tension nuts 7 are provided at both ends of the tension bolt 9 , and the two blocking angle steels 8 of the bottom blocking mechanism 6 and the corresponding supporting steel pipe 3 are locked.

[0036] like Figure 5 As shown, a clamping mechanism is further provided on the inner side of the blocking angle steels 8 on both sides of the bottom blocking mechanism 6, which respectively positions the two prefabricated wall bodies 5. The clamping mechanism includes a plurality of clamping members 12 fixed to the bottom of the prefabricated wall body 5 and a plurality of clamping members 13 fixed to the ground. The number and position of the clamping members 12 correspond one-to-one with the clamping members 13.

[0037] Further integration Figure 6 The card member 12 includes an outer card plate 16, which includes two staggered plate surfaces, wherein a tie rod 15 is fixed to the upper plate surface, and a stop rod 14 is fixed to the other end of the tie rod 15. The stop rod 14 is stuck inside the prefabricated wall 5. The stop rod 14 can be set inside the prefabricated wall 5 when the prefabricated wall 5 is manufactured. The tie rod 15 is vertically drawn out from the surface of the prefabricated wall 5 and fixed to the outer card plate 16. The outer card plate 16 is preferably fixed to the tie rod 15 by a threaded connection. After the outer card plate 16 is fixed to the tie rod 15, the outer card plate 16 is fixed by an external nut. At this time, a slot is formed between the lower surface of the outer card plate 16 and the prefabricated wall 5.

[0038] The bracket 13 includes an inner bracket 17 with an L-shaped cross-section. Multiple legs 18 are positioned at the bottom of the horizontal plate of the inner bracket 17. These legs 18 secure the bracket 13 to the upper surface of the structural beam 7. Before the prefabricated walls 5 are laid out, the bracket 13 is pre-placed on the surface of the structural beam 7. When the prefabricated walls 5 are laid out, the outer bracket 16 engages the outer side of the inner bracket 17, securing and positioning the prefabricated walls 5.

[0039] The specific working process and working principle are as follows:

[0040] Two prefabricated walls 5 are arranged at a predetermined interval and positioned using the bottom clamping mechanism. Connecting steel bars 1 are then placed on the inner sides of the two prefabricated walls 5. Lumber assemblies, steel pipe assemblies, and bottom sealing mechanisms 6 are placed on the outer sides of the two prefabricated walls 5. Finally, the rail assembly and bottom sealing mechanisms 6 are secured using a sufficient number of tensioning assemblies 2.

[0041] Then, concrete is poured between the two prefabricated walls 5. After the pouring is completed and solidified, the square timbers 4, supporting steel pipes 3, and blocking angle steels 8 on the surfaces of the two prefabricated walls 5 are removed. Since a sealing gasket 10 is provided at the horizontal surface of the blocking angle steel 8, the sealing gasket 10 seals the blocking angle steel 10 from the ground. Therefore, when pouring concrete, leakage and slurry runaway at the bottom of the prefabricated wall 5 are avoided.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
