Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a detachable structural column concrete pouring device. Background Technology

[0002] With the rapid development of my country's construction industry, infill wall masonry engineering has been widely used in civil and industrial buildings. As an important component of infill wall masonry engineering, the construction quality of structural columns directly affects the safety and durability of the building structure. The main function of structural columns is to enhance the integrity and stability of the wall, especially in seismic design, where they can effectively improve the shear strength and ductility of the wall.

[0003] However, existing construction techniques for structural columns present numerous problems in the concrete pouring stage. Traditional methods typically involve creating a "flared" opening at the top side of the column, through which concrete is poured into the formwork. After the concrete has hardened, excess concrete must be removed, and the surface repaired to achieve the required smoothness and aesthetic quality. This construction method suffers from the following main drawbacks:

[0004] (1) Unstable construction quality:

[0005] The installation and fixation of the "flared end" depends on the skill level of the on-site workers. If the "flared end" is not stable, it is easy to fall off during the pouring process, resulting in quality defects such as holes and honeycombing at the top of the structural column. In addition, improper operation during the chiseling and repair process can also affect the overall appearance quality of the structural column.

[0006] (2) High post-processing costs:

[0007] Traditional pouring methods require extensive chipping and repair of excess concrete, which not only increases the number of construction steps but may also lead to problems such as cracks or insufficient strength on the surface of the structural column, thereby increasing the cost and time of rectifying quality defects.

[0008] (3) Low construction efficiency:

[0009] In traditional processes, after the concrete of the structural column is poured, it is necessary to wait for the concrete to fully solidify before chiseling and repair can be carried out. This process is time-consuming and affects the overall construction progress.

[0010] (4) Environmental protection and sustainability issues:

[0011] The waste concrete and repair materials generated by traditional chiseling processes not only waste resources but may also have adverse environmental impacts. Utility Model Content

[0012] The purpose of this invention is to provide a detachable concrete pouring device for structural columns to solve the problems mentioned above.

[0013] The technical solution adopted by this utility model is: a detachable structural column concrete pouring device, which includes a structural column template, a hopper and a blade-shaped baffle. The side end of the hopper is provided with a material transfer port, which corresponds to the material inlet on the structural column template and can convey slurry to the material inlet. The blade-shaped baffle is movably arranged at the material transfer port and can cut off part or all of the channel between the material transfer port and the material inlet.

[0014] Furthermore, the blade-shaped baffle is provided with a scraping inclined surface, which is located at the side end of the blade-shaped baffle and faces away from the feed port.

[0016] Furthermore, the structural column template is provided with a baffle groove, which is located below the feed inlet and extends along the width of the feed inlet. The blade-shaped baffle is slidably disposed in the baffle groove.

[0017] Furthermore, the hopper includes a semi-conical hopper section and a connecting plate. The semi-conical hopper section is located at the top of the connecting plate, the material inlet is located at the side end of the semi-conical hopper section, and the connecting plate is provided with a detachable fixing member for connecting the structural column template.

[0018] Furthermore, the semi-conical bucket includes a first side plate and a second side plate arranged in parallel, and an inclined plate connecting the first side plate and the second side plate. The inclined plate is opposite to the material conveying port. The width of the second side plate is greater than the width of the first side plate. The first side plate abuts against the structural column template, and the second side plate abuts against the knife-shaped baffle.

[0019] Furthermore, the detachable fastener includes an anchor nail and a U-shaped hoop. The anchor nail connects the connecting plate to the structural column template on the same side of the connecting plate. The connecting plate is located inside the U-shaped hoop, and the end of the U-shaped hoop passes through the structural column template on the same side and the opposite side of the hoop in sequence.

[0020] Furthermore, the end of the U-shaped hoop is threaded, and a steel washer and a high-strength nut are fitted onto it.

[0021] Furthermore, the top of the semi-conical bucket is 50mm to 100mm higher than the top of the structural column template.

[0022] The beneficial effects of this utility model are as follows: by setting up the blade-shaped baffle, the additional costs and time caused by chiseling and repair in traditional processes are reduced, while the impact of chiseling and repair on the appearance quality is reduced, the construction progress is accelerated, and the generation of waste concrete and repair materials is reduced, which meets the needs of environmental protection and sustainable development; through the dual fixing effect of anchor nails and U-shaped hoops, the connection stability between the hopper and the structural column formwork can be improved, avoiding quality defects caused by unstable formwork or hopper, and improving the construction quality.

[0033] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0035] Reference Appendix Figure 1-4 This embodiment discloses a detachable structural column concrete pouring device, which includes a structural column template, a hopper 1, and a blade-shaped baffle 2. To clearly illustrate this technical solution, the structural column templates located on both sides of the wall are distinguished as: same-side structural column template 3 and opposite-side structural column template 4. The same-side structural column template 3 and the hopper 1 are located on the same side of the wall, while the opposite-side structural column template 4 and the hopper 1 are located on opposite sides of the wall, meaning the same-side structural column template 3 and the opposite-side structural column template 4 are arranged opposite each other. The top of the same-side structural column template 3... The top of the hopper 1 is lower than the top of the opposite structural column template 4. The top of the same side structural column template 3 and the wall edges on both sides of the structural column area form the inlet 31, which is used to pour slurry into the structural column area. The hopper 1 is detachably connected to the same side structural column template 3. Its side end is provided with a material transfer port 11, which corresponds to the inlet 31 and can convey slurry to the inlet 31. The blade-shaped baffle 2 is movably installed at the material transfer port 11. By moving the blade-shaped baffle 2, the channel between the material transfer port 11 and the inlet 31 can be partially or completely cut off.

[0036] More specifically, the blade-shaped baffle 2 can be formed by cutting a regular plate. The purpose of cutting is to create a scraping slope 21 on the blade-shaped baffle 2. The scraping slope 21 is located on the side end of the blade-shaped baffle 2, facing away from the feed inlet 31 and facing the conveying inlet 11, so that the side end of the blade-shaped baffle 2 forms a shape similar to a blade. This allows the slurry exceeding the area of ​​the structural column to be more easily scraped off by the blade-shaped baffle 2 into the hopper 1, avoiding the need for large-area scraping of excess material from the feed inlet 31 after the concrete of the structural column has set.

[0037] During construction, the above-mentioned structures are assembled and fixed. Grout is injected into the structural column area from hopper 1 until the grout level in hopper 1 no longer decreases. Then, the blade-shaped baffle 2 is moved to partially or completely cut off the channel between the feed port 11 and the inlet 31. The grout in the structural column area is then vibrated and compacted until it sets and settles before demolding. During the vibration and compaction of the grout, additional grout can be added to the top of the structural column formwork until the required elevation for the structural column is met.

[0038] When the complete cut-off method is adopted, the blade-shaped baffle 2 can be constructed into a complete plate to completely block the material inlet 11. Since the grouting is only a small amount of grout, the impact on the structural column formwork and the structural column is not significant. By controlling the grouting flow rate, grouting can be applied vertically at the top of the structural column formwork without affecting the construction quality of the structural column. When the partial cut-off method is adopted, the blade-shaped baffle 2 can still completely block the material inlet 11 on its outer contour. However, several material filling holes 22 can be constructed on the blade-shaped baffle 2. The two ends of the material filling holes 22 are connected to the material inlet 11 and the inlet 31, respectively. After the grout in the structural column area settles, the grout in the hopper 1 can automatically enter the structural column area through the material filling holes 22.

[0039] To meet the installation and movement requirements of the blade-shaped baffle 2, please refer to the attached document. Figure 3 The structural column template is provided with a baffle groove 32, which is located below the feed inlet 31 and extends along the width of the feed inlet 31. The knife-shaped baffle 2 is slidably disposed in the baffle groove 32. The hopper 1 includes a semi-conical hopper 12 and a connecting plate 13. The semi-conical hopper 12 is disposed at the top of the connecting plate 13, and the feed inlet 11 is disposed at the side end of the semi-conical hopper 12. The connecting plate 13 is provided with a detachable fixing member 5 for connecting the structural column template. The semi-conical hopper 12 includes a first side plate 121 and a second side plate 122 disposed in parallel, and an inclined plate 123 connecting the first side plate 121 and the second side plate 122. The inclined plate 123 is opposite to the feed inlet 11. The width of the second side plate 122 is greater than the width of the first side plate 121. The first side plate 121 abuts against the structural column template, and the second side plate 122 abuts against the knife-shaped baffle 2. The above structure ensures tight fit between structural plates and smooth sliding of the blade-shaped baffle 2.

[0040] The detachable fastener 5 includes anchor nails 52 and U-shaped clamps 52. The anchor nails 52 connect the same-side structural column template 3 and the connecting plate 13. The connecting plate 13 is located inside the U-shaped clamps 52. The ends of the U-shaped clamps 52 pass through the same-side structural column template 3 and the opposite-side structural column template 4 in sequence before being tightened. Through the double tightening action of the anchor nails 52 and the U-shaped clamps 52, the connection stability between the hopper 1 and the structural column template can be ensured. After the structural column has solidified, the U-shaped clamps 52, anchor nails 52, hopper 1, blade-shaped baffle 2, and other structures can be removed and reused, saving costs.

[0041] To facilitate installation and disassembly, threads can be made at the end of the U-shaped hoop 52, and a steel washer 53 and a high-strength nut 54 can be fitted onto it, so that the steel washer 53 is pressed against the opposite side structural column template 4 by the high-strength nut 54.

[0042] More preferably, the top of the blade-shaped baffle 2 is flush with the top of the semi-conical hopper 12, and the top of the semi-conical hopper 12 is 50mm to 100mm higher than the top of the structural column template, so that when the concrete in the structural column area undergoes settling and settlement, the slurry in the semi-conical hopper 12 will flow into the structural column area through the filling hole 22 on the blade-shaped baffle 2 to replenish it due to the pressure difference.

[0043] In addition, the filling holes 22 on the blade-shaped baffle 2 should not be too large or too small. If they are too large, the area to be chiseled later will be increased; if they are too small, it will be difficult for solid materials in the grout to pass through, thereby reducing the construction quality of the top of the structural column. Preferably, the diameter of the filling holes 22 should not be less than 1.25 times the particle size of the coarse aggregate in the grout. The specific diameter and number of filling holes 22 can be configured by the on-site construction personnel according to the needs, with the main basis being to meet the filling requirements and minimize the area to be chiseled after demolding. No further restrictions are imposed here.

[0044] Compared with the prior art, the beneficial effects of this utility model include: by setting the blade-shaped baffle 2, the additional costs and time caused by chiseling and repair in the traditional process are reduced, while the impact of chiseling and repair on the appearance quality is reduced, the construction progress is accelerated, and the generation of waste concrete and repair materials is reduced, which meets the needs of environmental protection and sustainable development; through the dual fixing effect of anchor nails 52 and U-shaped hoops 52, the connection stability between hopper 1 and structural column formwork can be improved, avoiding quality defects caused by instability of formwork or hopper 1, and improving construction quality.

[0045] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
