Description

Technical Field

[0001] This utility model relates to the field of secondary structure construction technology, specifically to a non-pull-out formwork structure for structural columns. Background Technology

[0002] As a core component of the secondary structural system, structural columns play a crucial role in enhancing the overall stability and integrity of the structure. Structural columns are typically placed at the four corners of exterior walls, at the intersections of horizontal and vertical walls in staggered floor areas, and on both sides of large openings. In multi-story brick-concrete structures, reinforced concrete structural columns are added inside the walls and connected to the ring beams of each floor to enhance their bending and shear resistance. Traditionally, structural column construction uses wooden formwork in conjunction with steel pipes and tie rods for support. During the formwork erection phase, numerous tie rods are needed to secure the wooden formwork and ensure the stability of the wooden structure. However, after the concrete hardens, demolding often damages the wooden formwork, and the tie rods cannot be recycled. Cutting off both ends of the tie rods may leave gaps in the structural column, leading to localized defects and affecting its overall performance. Furthermore, the overall formwork erection and demolding process is cumbersome, and the material reuse rate is relatively low.

[0003] To address the shortcomings of existing technologies, there is an urgent need for a non-tension formwork structure for structural columns. This new formwork structure simplifies the formwork erection and dismantling process for structural columns and reduces material waste costs. Utility Model Content

[0004] The present invention aims to provide a non-tension formwork structure for structural columns, which effectively solves the problems of cumbersome formwork erection and dismantling procedures and high material loss in current structural column construction, thereby improving the construction efficiency and effect of structural columns.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-tension formwork structure for structural columns includes a base plate, a formwork mechanism, and a clamping mechanism. The formwork mechanism consists of modularly arranged assembly templates, which are divided into a top template, a middle template, and a bottom template. The assembly templates are detachably connected. The top template has a feeding hopper and an upper clamping block, and the bottom template has a lower clamping block. One end of the base plate is rotatably connected to the bottom end of the bottom template. The base plate has a rotatably connected fixing rod, the free end of which is detachably connected to the bottom template. When the fixing rod is in place, the base plate and the bottom template are perpendicular to each other. The clamping mechanism includes at least two support plates and two telescopic top rods. The lower parts of the two telescopic top rods are detachably connected to both sides of the base plate, and the upper parts of the telescopic top rods are detachably connected to the support plates. The support plates are clamped between the upper and lower clamping blocks.

[0007] The principles and advantages of this scheme are:

[0008] Traditional wooden formwork erection and dismantling are cumbersome, labor-intensive, and consume a large amount of materials. This solution, designed to optimize construction procedures and reduce material waste, utilizes a non-tensioned formwork structure. This eliminates the need for tie rods and the need for prefabricated wooden formwork. The modular assembly formwork structure is directly calculated and allocated, allowing for rapid assembly. This structure enables construction workers to more easily position and secure the formwork, and allows for quick, non-destructive dismantling after concrete pouring and setting. This significantly shortens the construction cycle and reduces material and labor costs. The modular design of the formwork structure facilitates assembly and dismantling, improving construction efficiency. Furthermore, the absence of tie rods eliminates gaps in structural columns, enhancing the overall structural performance. In addition, compared to traditional wooden formwork structures, this assembled formwork structure boasts higher strength, is recyclable, and reduces resource waste.

[0009] Preferably, as an improvement, the assembly template is provided with a slot mechanism, which includes a T-slot and a T-block that cooperate with each other, and the T-slot and the T-block are respectively set at the top and bottom of the assembly template.

[0010] The connection between assembly templates is usually fixed by bolts, which is cumbersome and time-consuming. By setting a slot mechanism, the connection between assembly templates can be completed more quickly, and it is firm and reliable.

[0011] Preferably, as an improvement, the assembly template is provided with a mortise and tenon mechanism, with tenons on both sides of the upper part of the assembly template and mortises on both sides of the lower part of the assembly template corresponding to the tenons. The assembly templates are connected by mortise and tenon joints, and the bottom of the bottom template and the top of the top template are planar structures.

[0012] The connection method between the assembly templates is further optimized. The slot mechanism requires manual adjustment for alignment, and the smoothness of the slot mechanism may be affected after a period of use. Disassembly and installation are relatively laborious. By setting the tenon and mortise mechanism, the connection between the assembly templates can be completed quickly. The tenon and mortise mechanism has shallow grooves, which are easy to maintain and prevent the smoothness from decreasing. It will not have problems such as left and right sliding, and is firm and reliable.

[0013] Preferably, as an improvement, the assembly template is also provided with a locking mechanism. The locking mechanism includes a locking groove, a locking shaft, and locking clips and knobs fixed at both ends of the locking shaft. The locking groove includes an upper locking groove and a lower locking groove, which are respectively located in the middle of the top of the assembly template and the middle of the bottom of the template. The locking shaft passes through the side wall of the lower locking groove, the locking clip is located in the lower locking groove, and the knob is located outside the lower locking groove. A locking rod is provided in the upper locking groove, and the locking clip engages with the locking rod after rotation.

[0014] To improve the ease of disassembly and assembly of the template and the stability of the connection, a locking mechanism is provided. An upper locking groove and a lower locking groove are provided at the connection of the template. A locking rod is provided in the upper locking groove, and a locking clip with a knob is provided in the lower locking groove. The template can be locked and released quickly and easily by turning the knob, which further improves the ease of operation.

[0015] Preferably, as an improvement, the two telescopic top rods are screw mechanisms, including a nut block and rotating rods connected to both ends of the nut block. The two rotating rods are connected to the nut block with opposite thread directions. Each of the two rotating rods has a handle near the nut block. The free ends of the two rotating rods are respectively connected to the support plate and the base plate.

[0016] Considering the actual usage environment, a stable and reliable structure is required. Therefore, the telescopic top rod is designed as a screw mechanism, which is reliable, stable, and easy to operate. By setting opposite thread directions, the telescopic length can be adjusted by rotating the two screw rods simultaneously with the handle, which improves the applicability and support efficiency.

[0017] Preferably, as an improvement, blind holes are provided on the opposite surfaces of the two support plates, and a telescopically adjustable connecting rod is provided between the blind holes.

[0018] To improve the overall integrity and stability of the two support plates, a connecting rod is installed between them. In addition, to accommodate different widths, the connecting rod is made telescopic, which allows for direct adjustment for different widths. This not only improves the stability of the two support plates but also expands the applicability of the device.

[0019] Preferably, as an improvement, an adjustment mechanism is provided at the end of the base plate away from the assembly template. The adjustment mechanism includes a screw and adjustment knobs and adjustment blocks connected to both ends of the screw. The upper part of the adjustment mechanism is the adjustment knob, the lower part is the adjustment block, and the middle part of the screw is rotatably connected to the base plate perpendicular to the base plate surface.

[0020] In practical applications, there may be some uneven areas. Rotating the adjustment knob will cause the screw to move up and down, and the adjustment block will rise and fall accordingly. By setting an adjustment mechanism, the base plate can be leveled, and the fastening force can be increased to prevent the base plate from sliding, ensuring that the base plate is level and enhancing the stability of the device.

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings of the instruction manual include: base plate 1, template mechanism 2, adjustment mechanism 3, tightening mechanism 4, locking mechanism 5, slot mechanism 6, wall surface 7, structural column 8, fixing rod 101, handle 102, upper locking block 201, feed hopper 202, feed hole 203, tenon 204, mortise 205, lower locking block 206, upper locking groove 207, lower locking groove 208, adjusting knob 301, adjusting block 302, handle 401, nut block 402, rotating rod 403, support plate 404, connecting rod 405, locking clip 501, locking rod 502, knob 503, T-slot 601, T-block 602.

[0032] Example 1 is basically as shown in the appendix. Figure 1-6 and attached Figure 9 As shown:

[0033] As attached Figure 1 As shown, a non-tension formwork structure for structural columns includes a base plate 1, a formwork mechanism 2, a tightening mechanism 4, an adjusting mechanism 3, and a slotting mechanism 6. The formwork mechanism 2 is an assembly formwork set according to modules, which can be divided into top formwork, middle formwork, and bottom formwork according to the installation position. The left end of the base plate 1 is hinged to the bottom formwork, and the right end of the base plate 1 is provided with a handle 102. The lower part of the base plate 1 is provided with an anti-slip structure, and the left side of the base plate is provided with a fixing rod 101. The upper end of the fixing rod 101 is detachably connected to the bottom formwork, and the lower end is rotatably connected to the left end of the base plate 1. After the fixing rod 101 is locked, the formwork mechanism 2 and the base plate 1 are in a vertical state. The modular design of assembling the formwork according to modules can reduce material waste and improve convenience. The fixing rod 101 is used for initial locking to prevent the formwork mechanism 2 from rotating.

[0034] As attached Figure 2 As shown, the right end of the base plate 1 has a threaded hole and a space for accommodating the adjusting block. The adjusting mechanism 3 includes an adjusting knob 301 and an adjusting block 302. The adjusting mechanism 3 is a screw structure, with the adjusting knob 301 at the top, the adjusting block 302 at the bottom, and the screw in the middle rotatably connected in the threaded hole. The adjusting mechanism 3 can not only be used to level the base plate 1, but also improve the fastening and anti-slip effect.

[0035] As attached Figure 6 The assembly template shown is equipped with a slot mechanism 6, which includes a T-slot 601 and a T-block 602 that cooperate with each other. The T-slot 601 is located at the top of the assembly template, and the T-block 602 is located at the bottom of the assembly template. The top of the top template and the bottom of the bottom template do not have T-slots 601 and T-blocks 602. The assembly template is connected and fixed through this slot mechanism 6. The middle of the top template is provided with a feed hopper 202 and a feed hole 203. An upper locking block 201 is also provided below the feed hopper 202 of the top template. The upper part of the top template is a planar structure, and the lower part of the top template is connected to the attached... Figure 6 The structure shown in the upper part on the right is consistent. The lower part of the bottom template is also a planar structure, and the upper structure is the same as the attached one. Figure 6 The upper part on the left side has the same structure as shown, and the bottom template is provided with a lower locking block 206. The T-slot 601 and T-block 602 are reliable in structure, and the assembly template can be assembled and fixed relatively quickly through this locking mechanism 6 to prevent the assembly template from sliding up and down and causing gaps.

[0036] As attached Figure 3 As shown, the tightening mechanism 4 includes a handle 401, a nut block 402, a rotating rod 403, a support plate 404, and a connecting rod 405. The rotating rod 403 is divided into two sections, which are rotatably connected to the nut block 402. The threads at the connection points of the two sections of the rotating rod and the nut block 402 are opposite. The upper part of the upper rotating rod 403 is bolted to the support plate 404, and the lower part of the lower rotating rod 403 is bolted to the right end of the base plate 1. Each section of the rotating rod 403 has a handle 401 on the side near the nut block 402, as shown in the attached diagram. Figure 3 As shown in the enlarged partial structure, the rotating rod near the bolt connection is a rotatable structure. By rotating the handle 401, the rotating rod 403 is extended, causing the support plate 404 to press against the template mechanism 2. The structure of the support plate 404 is shown in the attached figure. Figure 4As shown, the device includes two vertical support plates 404 and two horizontal connecting rods 405. The opposing sides of the two support plates 404 have blind holes for inserting the connecting rods 405. The connecting rods 405 have adjustable telescopic lengths with clearly defined adjustment positions. When manually rotated, their extension lengths are consistent within a certain rotation range. Adjusting the connecting rods 405 allows for easy alignment of the telescopic lengths of the two connecting rods. The structure after the connecting rods 405 are inserted into the blind holes and connected is shown in the attached figure. Figure 4 As shown on the right, the overall layout in actual use is as shown in the attached figure. Figure 5 As shown on the left. The connecting rod 405 effectively connects the support plates 404 on both sides into a whole, improving support stability. In addition, the telescopic design can adapt to different widths, improving applicability.

[0037] The non-pull formwork structure of this solution enables rapid modular assembly and formwork support, optimizing the construction process. It not only allows for quick completion of formwork support and dismantling operations but also reduces material waste. Furthermore, the formed structural columns have smooth eight sides without holes or gaps, improving the overall construction effect.

[0038] The specific implementation method is as follows:

[0039] First, calculate the required number of templates to be assembled based on the wall height. Then, unfold the base plate 1 close to the wall and assemble the modular templates. Align the T-blocks 602 of the templates with the T-slots 601 and insert them so that the sides of the two plates are flush, facilitating the connection and fixing between the templates. Complete the connection of all the templates in sequence. Push and rotate the template mechanism 2 after connection so that it fits against the wall surface 7. Place the corner locking rods 502 in place for initial locking. Then, grasp the handle 401 on the rotating rod 403 and rotate it so that the upper part of the support plates 404 on both sides is engaged between the upper locking block 201 and the lower locking block 206. The connecting rod 405 connects the support plates 404 on both sides to form a whole. Continue to rotate the handle 401 to press the template mechanism 2. If the ground is uneven, adjust it using the adjusting mechanism 3. The above operations complete the formwork erection operation. The overall structure after completion is shown in the attached figure. Figure 9 As shown, concrete is poured into the feed hopper 202. After the structural column is formed, the support plate 404 is released by rotating the handle 401, facilitating a quick and easy demolding operation. During disassembly, one of the assembly templates is pushed to slide the T-block 602 out of the T-slot 601, thus completing the disassembly of the assembly template. Then, all components are collected for future use. The formed structural column is shown in the attached figure. Figure 5 As shown on the right.

[0040] Example 2 is attached. Figure 1-5 and attached Figure 7-9 As shown:

[0041] Unlike Embodiment 1, this embodiment features a non-tension formwork structure for structural columns, without a slotted mechanism 6, but including a locking mechanism 5. The structural form of the assembled formwork in this embodiment is shown in the attached figure. Figure 7 As shown, the assembly template has tenons 204 and mortises 205. The assembly templates are connected by tenon joints. The structure of the middle template is shown in the attached figure. Figure 7 As shown, the dimensions of the tenon 205 correspond to the dimensions of the tenon 204. The upper part of the assembly template is provided with the tenon 204 and the locking mechanism 5. A lower locking groove 208 is opened in the middle of the upper part of the assembly template, and there is a protruding structure in the middle of the right side. The locking mechanism 5 includes a locking clip 501 and a knob 503 connected and fixed to both ends of the locking shaft. The locking shaft passes through the lower locking groove 208. The locking clip 501 can be rotated by the knob 503, so that the locking clip 501 can rotate freely in the lower locking groove 208. (See attached image) Figure 8 As shown, lock 501 is arc-shaped. (Attached) Figure 7 The upper structure on the right is an appendix. Figure 7 The lower structure on the left includes a tenon 205 and a locking groove 207 in the middle. A locking rod 502 is provided in the locking groove 207. A groove with a mating protrusion is provided in the middle of the right side. The tenon 204 and tenon 205 structure allow for quick positioning and fixation, and the knob 503 quickly completes the locking process. This allows for convenient and quick connection between assembly templates, improving overall operational efficiency. The remaining parts are the same as in Embodiment 1 and will not be described again here. Detailed implementation method:

[0043] The difference from Embodiment 1 lies in the connection operation of the template mechanism 2. In actual operation, the tenon 204 is aligned with the locking groove for tenoning, and then the knob 503 is rotated to lock the locking rod 502 with the locking clip 501. The assembled template is quickly and initially fixed through tenoning, and then the knob 503 is rotated to complete the locking, which greatly improves the operation efficiency. The rest is the same as in Embodiment 1, and will not be described again here.

[0044] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
