Description

Technical Field

[0001] This invention patent relates to the technical field of optical well forming, and more specifically, to an optical well forming construction method that facilitates formwork construction. Background Technology

[0002] Optical wells have important applications in fields such as construction, and their main function is to guide light. However, the inconvenience of formwork during the construction of optical wells has always affected construction efficiency.

[0003] In existing technologies, traditional optical fiber well construction often uses wooden or steel formwork. In terms of formwork reinforcement, both wooden and steel formwork require additional reinforcement measures, which makes the formwork erection process time-consuming.

[0004] During the demolding stage, the formwork and concrete are prone to sticking together, and improper demolding can easily damage the light guide well. Therefore, the demolding process needs to be done carefully, which also increases the time cost of demolding.

[0005] Moreover, wooden formwork has a low turnover rate, and frequent formwork replacement affects the continuity of construction. The high cost of steel formwork prevents its widespread application in some projects, thus limiting its role in improving construction efficiency. At the same time, due to the shortcomings of traditional formwork in ensuring molding quality, subsequent repairs and other work are required, which indirectly reduces the construction efficiency of optical well molding. Summary of the Invention

[0006] The purpose of this invention is to provide a construction method for forming optical wells that facilitates formwork construction, aiming to solve the problem of low construction efficiency in the existing technology for forming optical wells.

[0007] This invention is implemented as follows: a method for constructing optical guide wells that facilitates formwork support, comprising the following construction steps:

[0008] 1) Arrange multiple horizontally curved panels, which are arranged sequentially around each other to form a ring-shaped inner template, and the inner template forms an inner cavity.

[0009] 2) A top connection structure is provided between the tops of adjacent curved panels, and the top connection structure fixes the tops of adjacent curved panels relative to each other;

[0010] 3) Insert an inner support structure into the inner cavity. The inner support structure has multiple inner support rods that swing inward or outward. The multiple inner support rods are arranged from the inside out to correspond to the multiple curved panels. Swing the multiple inner support rods outward by a set distance so that the multiple inner support rods abut against the multiple curved panels from the inside out, thereby restricting the bottom of the multiple curved panels from moving inward.

[0011] 4) An outer template is fitted around the outer periphery of the inner template, and an annular space is formed between the outer template and the inner template;

[0012] 5) Pour concrete into the annular space until the concrete reaches the top of the annular space;

[0013] 6) After the concrete in the annular space has solidified, the concrete forms a light guide well. The multiple inner support rods are swung inward by a set distance so that the inner support rods are detached from the curved panel. The inner support structure is then removed from the inner cavity, and the inner template and outer template are detached from the light guide well.

[0014] Furthermore, the curved panel has side edges on both sides. In construction step 2), when the tops of adjacent curved panels are connected by a top connecting structure, and there is a side gap between the side edges of adjacent curved panels, the side gap is filled and sealed.

[0015] Furthermore, in construction step 2), the inner and outer sides of the side partition have side openings, foam is filled into the side partition, and then the side openings are sealed with tape to close the side partition.

[0016] Furthermore, in construction step 2), the top of the curved panel has a top curved plate, which is arranged to bend along the bending direction of the curved panel. The top connecting structure is connected to the top curved plates of adjacent curved panels respectively, so that the tops of adjacent curved panels are relatively fixed.

[0017] Furthermore, in construction step 2), the top connecting structure includes a connecting plate that spans between adjacent top curved plates and abuts against the top curved plates. Bolts are provided on the connecting plate and pass through the top curved plates to fix the connecting plate to the top curved plates, so that the tops of adjacent curved plates are relatively fixed.

[0018] Furthermore, a lifting ring is protruding from the top curved plate. In construction step 2), after the tops of the multiple curved panels are relatively fixed, the inner template is hoisted to the construction position by connecting the lifting rope and the lifting ring. In construction step 6), after the inner support structure is removed from the inner cavity and the top connecting structure is separated from the curved panel, the multiple curved panels are hoisted upward by connecting the lifting rope and the lifting ring, so that the multiple curved panels are separated from the light guide well.

[0019] Furthermore, in construction step 1), the bottom of the curved panel is provided with a bottom curved plate, which is arranged to bend along the bending direction of the curved panel; the inner sidewall of the curved panel is provided with a plurality of longitudinally arranged reinforcing plates, the outer side of the reinforcing plates is connected to the inner sidewall of the curved panel, the inner side of the reinforcing plates extends toward the inner cavity, the top of the reinforcing plates is connected to the top curved plate, and the bottom of the reinforcing plates is connected to the bottom curved plate; in construction step 3), the inner support rod abuts against the reinforcing plate.

[0020] Furthermore, in construction step 3), the internal support structure includes a longitudinally arranged rotating rod, the lower part of which has a threaded section, and the outer periphery of which is formed with an external thread; a fixed plate is provided at the bottom of the threaded section, and the threaded section moves through the fixed plate; a longitudinally movable moving plate is provided at the upper part of the threaded section, and a nut is provided on the moving plate, the nut being threadedly connected to the threaded section, and the threaded section moving through the moving plate.

[0021] The movable disk is connected to multiple linkage structures, which are arranged at intervals around the circumference of the rotating rod, and the outer ends of the linkage structures are connected to the inner support rods.

[0022] In construction step 3), when multiple connecting rod structures are lowered into the inner cavity, the rotating rod is rotated in the forward direction, the nut drives the moving disk to move downward relative to the fixed disk, and the inner support rod swings outward until the inner support rod abuts against the curved panel.

[0023] In construction step 6), after the concrete in the annular space has solidified, the rotating rod is rotated in the opposite direction. The nut drives the moving disc to move upward relative to the fixed disc, and the inner support rod swings inward until the inner support rod disengages from the curved panel.

[0024] Furthermore, in construction step 3), the movable disk is provided with multiple upper connecting strips, and the fixed disk is provided with multiple lower connecting strips. The multiple upper and lower connecting strips are arranged at intervals around the circumference of the rotating rod. The connecting rod structure includes an upper swing rod and a lower swing rod. The inner end of the upper swing rod is hinged to the upper connecting strip, and the inner support rod is connected to the outer end of the upper swing rod. The inner end of the lower swing rod is hinged to the lower connecting strip, and the outer end of the lower swing rod is hinged to the middle of the upper swing rod.

[0025] In construction step 3), when the rotating rod rotates in the forward direction, the nut and the moving disc move downwards, and the upper and lower swing rods swing outwards respectively, causing the inner support rod to swing outwards; in construction step 6), when the rotating rod rotates in the reverse direction, the nut and the moving disc move upwards, and the upper and lower swing rods swing inwards respectively, causing the inner support rod to swing inwards.

[0026] Furthermore, in construction step 3), the reinforcing plate has a positioning groove that penetrates the inner side of the reinforcing plate, forming an upwardly inclined inner opening; the inner support rod has a middle section located between adjacent reinforcing plates; the inner wall of the curved panel is provided with an elastic block; the bottom of the elastic block is fixed to the bottom curved plate; the outer side of the elastic block is abutted against the inner wall of the curved panel; and the inner side of the elastic block is provided with a recessed groove.

[0027] During the forward rotation of the rotating rod, the inner support rod is embedded in the positioning groove through the inner opening, the middle section is embedded in the recessed groove, and the elastic block is squeezed and deformed outward. The elastic block applies an elastic force to the curved panel to expand outward.

[0028] Compared with existing technologies, the optical guide well forming construction method provided by this invention, which facilitates formwork construction, has the following technical advantages:

[0029] 1) By arranging multiple laterally curved panels to form the inner formwork, and using a top connecting structure to fix the tops of adjacent curved panels relative to each other, the construction of the inner formwork becomes more stable and convenient. After the concrete is poured, by swinging the inner support rods inward a set distance, the inner support rods can be detached from the curved panels, allowing the inner support structure to be easily removed, and thus the inner and outer formwork can be separated from the light guide well. This greatly simplifies the demolding process, reduces the time and labor costs required for demolding, and significantly improves construction efficiency.

[0030] 2) The internal support structure has multiple internal support rods that swing inward or outward, which can effectively limit the inward contraction movement of the bottom of the curved panel and ensure the stability of the shape and size of the inner formwork during the concrete pouring process. This not only improves the reliability of construction, but also reduces the risk of rework caused by formwork deformation, and further improves construction efficiency.

[0031] 3) Compared to traditional wooden formwork, curved panels and internal support structures are reusable, reducing the frequency of formwork replacement and lowering formwork wear costs; the convenient formwork erection and dismantling process reduces manpower and time investment during construction, thereby reducing construction costs; and the internal support structure effectively limits the deformation of the curved panels, ensuring the forming quality of the light guide well and reducing the need for subsequent finishing work.

[0045] Reference Figure 1-7 The image shows a preferred embodiment of the present invention.

[0046] A method for constructing a light guide well that facilitates formwork support includes the following steps:

[0047] 1) Arrange multiple horizontally curved panels 100, and arrange the multiple curved panels 100 in sequence to surround and form an inner template in the shape of a ring. The inner template surrounds and forms an inner cavity 101.

[0048] 2) A top connection structure is provided between the tops of adjacent curved panels 100, and the top connection structure fixes the tops of adjacent curved panels 100 relative to each other.

[0049] 3) An inner support structure is inserted into the inner cavity 101. The inner support structure has multiple inner support rods 200 that swing inward or outward. The multiple inner support rods 200 are arranged from the inside out to correspond to the multiple curved panels 100. The multiple inner support rods 200 are swinged outward by a set distance so that the multiple inner support rods 200 abut against the multiple curved panels 100 from the inside out, thereby restricting the bottom of the multiple curved panels 100 from moving inward.

[0050] 4) An outer template 102 is fitted around the outer periphery of the inner template, and an annular space 103 is formed between the outer template 102 and the inner template;

[0051] 5) Pour concrete into the annular space 103 until the concrete reaches the top of the annular space 103;

[0052] 6) After the concrete in the annular space 103 has solidified, the concrete forms a light guide well. Multiple inner support rods 200 are swung inward by a set distance so that the inner support rods 200 are detached from the curved panel 100. Then, the inner support structure is removed from the inner cavity 101, and the inner template and outer template 102 are detached from the light guide well.

[0053] The above-mentioned method for constructing optical guide wells, which facilitates formwork support, has the following technical advantages:

[0054] 1) By arranging multiple laterally curved panels 100 to form the inner formwork, and using a top connecting structure to fix the tops of adjacent curved panels 100 relative to each other, the construction of the inner formwork becomes more stable and convenient. After the concrete is poured, by swinging the inner support rods 200 inward by a set distance, the inner support rods 200 are detached from the curved panels 100, allowing the inner support structure to be easily removed, and thus the inner formwork and outer formwork 102 to be separated from the light guide well. This greatly simplifies the demolding process, reduces the time and labor costs required for demolding, and significantly improves construction efficiency.

[0055] 2) The internal support structure has multiple inward or outward swinging internal support rods 200, which can effectively limit the inward contraction movement of the bottom of the curved panel 100, ensuring the stability of the shape and size of the inner formwork during the concrete pouring process. This not only improves the reliability of construction, but also reduces the risk of rework caused by formwork deformation, and further improves construction efficiency.

[0056] 3) Compared with traditional wooden formwork, the curved panel 100 and the internal support structure are reusable, reducing the frequency of formwork replacement and lowering the cost of formwork wear; the convenient formwork erection and dismantling process reduces the manpower and time input during construction, thereby reducing construction costs; and the setting of the internal support structure can effectively limit the deformation of the curved panel 100, ensuring the forming quality of the light guide well and reducing the need for subsequent repair work.

[0057] In this embodiment, the curved panel 100 has side edges on both sides. In construction step 2), when the tops of adjacent curved panels 100 are connected by a top connecting structure, there is a side gap between the side edges of adjacent curved panels 100, and the side gap is filled and sealed.

[0058] This effectively prevents concrete from leaking from the side gaps, ensuring the smooth progress of the pouring process. At the same time, it improves the integrity and stability of the inner formwork, thereby guaranteeing the forming quality of the light guide well.

[0059] In this embodiment, in construction step 2), the inner and outer sides of the side partition have side openings respectively. Foam is filled into the side partition, and then the side openings are sealed with tape to close the side partition.

[0060] Using foam filling can provide good sealing and cushioning, further enhancing the sealing of the side gaps and preventing concrete leakage. At the same time, the foam material is lightweight, which will not increase the burden on the formwork and is also conducive to subsequent formwork removal operations.

[0061] In this embodiment, in construction step 2), the top of the curved panel 100 has a top curved plate 300, which is arranged to bend along the bending direction of the curved panel 100. The top connecting structure is connected to the top curved plate 300 of the adjacent curved panel 100 respectively, so that the tops of the adjacent curved panels 100 are relatively fixed.

[0062] By setting the top curved plate 300, the top connection of adjacent curved plates 100 is made tighter and stronger, which improves the stability and reliability of the top of the inner formwork, ensures that the shape of the formwork remains unchanged during the concrete pouring process, avoids the problem of formwork displacement caused by unstable top connection, and thus improves construction efficiency.

[0063] In this embodiment, in construction step 2), the top connection structure includes a connecting plate 301. The connecting plate 301 spans between adjacent top curved plates 300 and abuts against the top curved plates 300. Bolts 302 are passed through the connecting plate 301 and pass through the top curved plates 300 to fix the connecting plate 301 and the top curved plates 300 together, so that the tops of the adjacent curved plates 100 are relatively fixed.

[0064] The use of bolts 302 for connection has the advantages of being simple, strong, and easy to operate. It can quickly fix the top of adjacent curved panels 100, saving construction time and improving construction efficiency. The use of connecting plate 301 and bolts 302 can also ensure the stability of the connection and reduce the shaking of the template during construction, thereby ensuring the forming quality of the light guide well.

[0065] In this embodiment, a lifting ring 303 is protruding on the top curved plate 300. In construction step 2), after the tops of the multiple curved panels 100 are relatively fixed, the inner template is hoisted to the construction position by connecting the lifting rope with the lifting ring 303. In construction step 6), after the inner support structure is removed from the inner cavity 101 and the top connecting structure is separated from the curved panel 100, the multiple curved panels 100 are hoisted upward by connecting the lifting rope with the lifting ring 303, so that the multiple curved panels 100 are separated from the light guide well.

[0066] The installation of lifting ring 303 facilitates the hoisting and dismantling of the inner formwork, making the movement of the inner formwork during construction more labor-saving and efficient, reducing the difficulty and risk of manual handling, and improving the convenience and efficiency of construction.

[0067] In this embodiment, in construction step 1), the bottom of the curved panel 100 is provided with a bottom curved plate 108, which is bent along the bending direction of the curved panel 100; the inner sidewall of the curved panel 100 is provided with a plurality of longitudinally arranged reinforcing plates 104, the outer side of the reinforcing plates 104 is connected to the inner sidewall of the curved panel 100, the inner side of the reinforcing plates 104 extends toward the inner cavity 101, the top of the reinforcing plates 104 is connected to the top curved plate 300, and the bottom of the reinforcing plates 104 is connected to the bottom curved plate 108; in construction step 3), the inner support rod 200 abuts against the reinforcing plate 104.

[0068] The addition of the bottom curved plate 108 and the reinforcing plate 104 increases the strength and rigidity of the curved panel 100, enabling it to better withstand the lateral pressure generated during concrete pouring, reducing the risk of deformation of the curved panel 100, and ensuring the forming accuracy of the light guide well. The reinforcing plate 104 also provides a stable contact point for the inner support rod 200, ensuring the effectiveness of the inner support structure and thus improving the reliability of construction.

[0069] In this embodiment, in construction step 3), the internal support structure includes a longitudinally arranged rotating rod 201. The lower part of the rotating rod 201 has a threaded section 202, and the outer periphery of the threaded section 202 is formed with external threads. A fixed plate 203 is provided at the bottom of the threaded section 202, and the threaded section 202 moves through the fixed plate 203. A longitudinally movable moving plate 204 is provided at the upper part of the threaded section 202. A nut 205 is provided on the moving plate 204, and the nut 205 is threadedly connected to the threaded section 202. The threaded section 202 moves through the moving plate 204.

[0070] Multiple linkage structures are connected to the movable disk 204. The multiple linkage structures are arranged around the rotating rod 201 at intervals in the circumference. The outer ends of the linkage structures are connected to the inner support rods 200.

[0071] In construction step 3), when multiple connecting rod structures are lowered into the inner cavity 101, the rotating rod 201 is rotated in the forward direction, and the nut 205 drives the moving disk 204 to move downward relative to the fixed disk 203, and the inner support rod 200 swings outward until the inner support rod 200 abuts against the curved panel 100.

[0072] In construction step 6), after the concrete in the annular space 103 has solidified, the rotating rod 201 is rotated in the opposite direction, and the nut 205 drives the moving plate 204 to move upward relative to the fixed plate 203, and the inner support rod 200 swings inward until the inner support rod 200 is disengaged from the curved panel 100.

[0073] This internal support structure allows for rapid expansion and contraction of the internal support rod 200 through simple rotation, making it easy to operate and effectively saving time in formwork erection and dismantling, thus improving construction efficiency. At the same time, the internal support structure has good stability and can reliably fix the curved panel 100, ensuring the forming quality of the light guide well.

[0074] In this embodiment, in construction step 3), the movable disk 204 is provided with multiple upper connecting strips 206, and the fixed disk 203 is provided with multiple lower connecting strips 207. The multiple upper connecting strips 206 and lower connecting strips 207 are arranged around the circumference of the rotating rod 201 at intervals. The connecting rod structure includes an upper swing rod 208 and a lower swing rod 209. The inner end of the upper swing rod 208 is hinged to the upper connecting strip 206, and the inner support rod 200 is connected to the outer end of the upper swing rod 208. The inner end of the lower swing rod 209 is hinged to the lower connecting strip 207, and the outer end of the lower swing rod 209 is hinged to the middle part of the upper swing rod 208.

[0075] In construction step 3), when the rotating rod 201 rotates in the forward direction, the nut 205 and the moving disk 204 move downwards, and the upper swing rod 208 and the lower swing rod 209 swing outwards respectively, causing the inner support rod 200 to swing outwards; in construction step 6), when the rotating rod 201 rotates in the reverse direction, the nut 205 and the moving disk 204 move upwards, and the upper swing rod 208 and the lower swing rod 209 swing inwards respectively, causing the inner support rod 200 to swing inwards.

[0076] This linkage structure makes the swing of the inner support rod 200 more stable and precise, ensuring reliable contact and disengagement between the inner support rod 200 and the curved panel 100, improving the reliability and efficiency of construction, and ensuring the smooth progress of the formwork erection and dismantling process.

[0077] In this embodiment, in construction step 3), the reinforcing plate 104 has a positioning groove that penetrates the inner side of the reinforcing plate 104, forming an upwardly inclined inner opening 105; the inner support rod 200 has a middle section 106 located between adjacent reinforcing plates 104; the inner wall of the curved panel 100 is provided with an elastic block 107; the bottom of the elastic block 107 is fixed on the bottom curved plate 108; the outer side of the elastic block 107 is abutted against the inner wall of the curved panel 100; and the inner side of the elastic block 107 is provided with a recessed groove.

[0078] During the forward rotation of the rotating rod 201, the inner support rod 200 is embedded in the positioning groove through the inner opening 105, the middle section 106 is embedded in the recessed groove, and the elastic block 107 is squeezed and deformed outward. The elastic block 107 applies an elastic force to the curved panel 100 to expand outward.

[0079] This not only enhances the connection stability between the inner strut 200 and the reinforcing plate 104, ensuring the accurate positioning of the inner strut 200, but also provides additional support for the curved panel 100 through the elastic force of the elastic block 107, enabling it to better resist the lateral pressure generated during concrete pouring and reducing the risk of deformation of the curved panel 100. At the same time, during demolding, the elastic force of the elastic block 107 helps the inner strut 200 to detach smoothly, improving the convenience of demolding.

[0080] The technical solutions in the embodiments of the present invention will be described in detail, clearly and completely below, so as to make the content of the optical guide well forming construction method that facilitates formwork construction easier to understand.

[0081] Construction method for forming optical guide wells that facilitates formwork construction:

[0082] 1. The inner formwork is mainly made of metal with a diameter of 600mm. The inner formwork mainly consists of curved panels and an internal support structure. There are three curved panels, each covering a 120° angle area. The spacing between adjacent curved panels is 5mm (as a movement space during demolding). Angle steel is installed inside the curved panels as vertical reinforcing ribs. A circumferential reinforcing rib is welded to the bottom of the curved panels to prevent the internal support structure from sliding down and to serve as the main stress point during formwork reinforcement. A circumferential reinforcing rib is welded to the top of the curved panels, and lifting rings are welded on for easy installation.

[0083] 2. The internal support structure is not connected to the curved panel. The distance between the two discs is adjusted by the movable part of the nut, thereby adjusting the support through the movable mechanical structure and fixing it against the curved panel. The disc near the nut is not connected to the nut or the reinforcing bar. The bottom disc is welded to the reinforcing bar. Two small sections of reinforcing bar are welded to the ends of the thread to limit the range of motion of the nut and prevent it from falling off.

[0084] 3. During construction, multiple horizontally curved panels are first arranged, and the multiple curved panels are arranged in sequence to form a ring-shaped inner template. The inner template forms an inner cavity. A top connection structure is provided between the tops of adjacent curved panels, and the top connection structure fixes the tops of adjacent curved panels relative to each other.

[0085] An inner support structure is inserted into the inner cavity. The inner support structure has multiple inner support rods that swing inward or outward. The multiple inner support rods are arranged from the inside out to correspond to multiple curved panels. The multiple inner support rods are swung outward by a set distance so that the multiple inner support rods abut against the multiple curved panels from the inside out, thereby restricting the bottom of the multiple curved panels from moving inward.

[0086] An outer formwork is fitted around the inner formwork, with an annular space between the outer and inner formwork. Concrete is poured into the annular space until it reaches the top. After the concrete in the annular space solidifies, it forms a light guide well. Multiple inner support rods are swung inward by a set distance so that they detach from the curved panel. The inner support structure is then removed from the inner cavity, and the inner and outer formworks are detached from the light guide well.

[0087] 4. After the hinges are installed, the top is connected with equilateral angle steel bolts to fix the three curved panels. The gaps between the curved panels are filled with foam and then sealed with tape to prevent grout leakage. Finally, the entire assembly is hoisted into place. The inner formwork is fixed in place by the lifting rings to prevent it from sliding down as a whole.

[0088] 5. After the concrete reaches the allowable demolding strength, rotate the central screw to make the support frame shrink inward, then remove the inner support structure, and finally loosen the bolts fixing the top angle steel plate and remove the curved panels of the formwork one by one.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
