Description

Technical Field

[0001] The present invention relates to the field of building technology, in particular to a support-free component used for a lightweight partition wall structural column and a construction method. Background Art

[0002] At present, my country's construction industry is in a stage of rapid development, and the development trend of prefabricated buildings is becoming more and more common. Lightweight partition wall construction, as an important part of prefabricated construction, has become increasingly common in market applications. However, in the construction of lightweight partition walls, how to ensure the construction quality of structural columns and how to prevent lightweight partition walls from cracking is a common technical difficulty.

[0003] When the installation length of the slatted partition wall in an earthquake-resistant area exceeds 6m, structural columns should be installed and reinforcement measures should be taken.

[0004] Conventional infill wall masonry column construction, employing formwork reinforcement and pre-reserved openings, has become increasingly mature. Traditional column formwork often utilizes repetitively used, fragmented formwork and wooden beams as primary and secondary ribs. This requires on-site assembly, requiring the complex preparation of formwork to the required height based on site needs. The construction process for lightweight partition wall columns remains limited. Lightweight partition walls are generally weak, and using formwork reinforcement can easily damage the partition wall, failing to guarantee the quality of the column construction.

[0005] Therefore, there is an urgent need for a lightweight partition wall structural column structure that is convenient to construct, has a short construction period, and does not require formwork to solve the above technical problems. Summary of the Invention

[0006] In response to the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a support-free component and a construction method for lightweight partition wall structural columns. The purpose of designing the support-free component is to facilitate construction, shorten the construction period and eliminate the need for formwork. The purpose of designing the construction method is to reduce the number of processes and reduce construction costs.

[0007] To solve the above technical problems, the present invention is implemented through the following solutions: A support-free component applied to a lightweight partition wall structural column of the present invention comprises:

[0008] The first prefabricated component has a first structure in which both lightweight partition walls opposite to the two vertical grooves are connected in a tongue-and-groove manner;

[0009] The second prefabricated component has a second structure that forms a tongue-and-groove connection with the two lightweight partition walls opposite the vertical grooves, an upper-open casting cavity is formed between the first prefabricated component, the second prefabricated component, and the two lightweight partition walls opposite the grooves, and the upper end of the second prefabricated component is lower than the first prefabricated component and lower than the two lightweight partition walls opposite the grooves;

[0010] a feeding funnel, provided on the outside of the second prefabricated component, having wings extending to both sides and entering the outer wall surfaces of the two lightweight partition walls, and an inclined funnel providing a pouring guide for the pouring cavity;

[0011] The strip-shaped member is arranged outside the first prefabricated member, and extends to both sides and enters the outer wall surfaces of the two lightweight partition walls. The feed funnel, the strip-shaped member, the first prefabricated member and the second prefabricated member are fixed by a locking member.

[0012] Furthermore, the first prefabricated component is integrally formed and has a first straight groove running through both ends, both ends of the first straight groove are bent outward to form a first wing, and a first right-angle groove is formed outside the first wing. The first right-angle groove is the first junction.

[0013] 1 structure.

[0014] Furthermore, the second prefabricated component is integrally formed and has a second straight groove running through both ends. Both ends of the second straight groove are bent outward to form second wings. A second right-angle groove is formed outside the second wing. The second right-angle groove is the second structure.

[0015] Furthermore, a gap is formed between the upper end of the second prefabricated component and the two lightweight partition walls, the feeding funnel seals the gap, and the inclined funnel and the gap are connected to form a casting channel.

[0016] Furthermore, the locking member is a bolt and nut.

[0017] Furthermore, the surface of the first prefabricated component facing the casting cavity is a rough surface.

[0018] Furthermore, the surface of the second prefabricated component facing the casting cavity is a rough surface.

[0019] Furthermore, the feed funnel is a prefabricated metal part, plastic part, or wooden part;

[0020] The strip-shaped component is a metal component, a plastic component, or a wooden component.

[0021] A construction method of the present invention comprises the following construction steps:

[0022] Step 1: Tie the structural column reinforcement cage;

[0023] Step 2: Use chalk lines to draw the corresponding width of the wall according to the position of the precast structural columns;

[0024] Step 3: Install a first lightweight partition wall on one side of the precast structural column;

[0025] Step 4: With the first lightweight partition wall as a base point, the position of the first prefabricated component is adjusted at the vertical groove of the first lightweight partition wall by tongue-and-groove connection. The contact surface and bottom of the first prefabricated component with the first lightweight partition wall are coated with partition wall sealing mortar, and the mortar is used to seal to prevent leakage and reinforce the first prefabricated component.

[0026] Install the second prefabricated component at the opposite position of the first prefabricated component, adjust the position of the second prefabricated component on the other side of the vertical groove by tongue and groove connection, and apply partition wall sealing mortar on the contact surface and bottom of the second prefabricated component and the first prefabricated component;

[0029] Step 7: Install the fourth lightweight partition wall by connecting the raised strips of the second lightweight partition wall and the vertical grooves of the fourth lightweight partition wall with a tongue-and-groove connection;

[0030] Step 8: After the sealing mortar in steps 4 and 5 reaches a preset strength, use the reserved holes reserved on the first prefabricated component and the second prefabricated component to first insert the PVC pipe into the reserved holes, and then lock and fix the feeding funnel, the strip component, the first prefabricated component, and the second prefabricated component with bolts and nuts;

[0031] Step nine: Use the concrete pouring pipe to pour concrete into the pouring port through the inclined funnel of the feed funnel. Then, the construction workers use a small vibrator to vibrate according to the construction requirements, and vibrate while pouring until the pouring cavity is filled.

[0032] Step 10, watering and curing the structural column formed by the concrete in the casting cavity;

[0033] 2 Step 11: After the concrete in step 10 solidifies, remove the bolts and nuts, then remove the feed funnel and strip-shaped components. After removing the bolts and nuts, chisel the outer openings of the first prefabricated component and the second prefabricated component to form a trumpet mouth, and finally use mortar to seal the two through holes formed after the removal.

[0034] Compared with the prior art, the present invention has the following beneficial effects:
