Description

Technical Field

[0001] The invention relates to the technical field of civil engineering construction, in particular to a polymer alloy template connecting piece and an installation method. Background Art

[0002] Polymer alloy formwork is a building forming alternative product that subverts the traditional forming process. It is formed by a variety of materials in a molten state through an extrusion process at one time, and there is no wastewater, gas, or slag in the production process. It saves time and labor during use, and demoulding is convenient and quick after pouring, unlocking and recyclable. A perfect closed-loop process is achieved from production to completion, in line with the policy guidance of the national energy-saving and environmental protection green arrow. At present, the products are widely used in highways, high-speed railways, subways, underground pipe galleries, water conservancy docks, bridges, construction of caps, piers, tie beams, cap beams, retaining walls, side walls and top plates of culverts, bottom plates and side ditches of cast-in-place box beams, and various prefabricated box beams, pedestals and bottom molds, prefabricated small box beams, various cylinders, square columns and other templates. They are widely used in the construction of wall, top plate, beam and column templates. Polymer alloy templates are generally prefabricated in the factory according to the size of the building structure, and assembled by workers after being transported to the construction site. The templates are spliced ​​and aligned with each other through the back ribs and then fastened with screws and nuts. The assembly of polymer alloy formwork is different from the installation of ordinary wooden formwork, and has the following characteristics:

[0003] First, designers must determine the various specifications of polymer alloy formwork according to the size of the building structure in advance, and the number of specifications should not be too many.

[0004] Second, after the polymer alloy formwork is prefabricated in the factory, it is directly assembled at the construction site. Since the size of the polymer alloy formwork is customized according to the size of the building structure, the polymer alloy formwork must be assembled tightly at the construction site.

[0005] Third, the longitudinal joints of the polymer alloy formwork will affect the overall rigidity of the formwork, so the longitudinal joints of the polymer alloy formwork should not be too many. In order to minimize the longitudinal joints, the length of a single polymer alloy formwork often exceeds 3m. This will make the weight of a single polymer alloy formwork greater than that of an ordinary wooden formwork.

[0006] Fourth, when using the polymer alloy template for the first time, you need to align the back ribs of the polymer alloy template first, and then drill holes on the sides of the back ribs of the two adjacent templates. When drilling, you must strictly control the direction of the drill bit to ensure that the direction of the holes on the back ribs of the two templates is perpendicular to the back ribs. Then put a gasket on the screw and align the screw with the direction of the hole and insert the screw into the hole of the back rib. When the screw passes through the hole, screw on the nut and tighten the nut with a wrench.

[0007] Fifth, when reusing polymer alloy templates, it is not advisable to drill holes repeatedly on the back ribs of the template. The original drilled holes should be used as much as possible to install screws. This requires that the holes between the back ribs of the template should also be aligned when spliced ​​for the second time.

[0008] Considering the actual situation of the above template splicing, the following problems will be encountered when splicing polymer alloy templates on site:

[0009] 1. It is difficult to strictly follow the drawings when splicing polymer alloy templates on site.

[0010] 2. When splicing polymer alloy templates, workers need to use pistol drills to drill holes, and it is difficult to ensure the verticality of the holes when drilling manually;

[0011] 3. When assembling the internal corner of the structure with the polymer alloy template, it is very difficult for the worker to drill the back edge of the internal corner with a pistol drill;

[0012] 4. When assembling the internal corners of the structure using polymer alloy templates, it is very difficult for workers to pass the screws through the drilled holes. They can only repeatedly adjust the angle of the screws by hand to find the hole at the other end.

[0013] 5. When the polymer alloy template is assembled for the second time, it is necessary to ensure that the screws can pass through the previously drilled holes. This requires workers to number the templates installed for the first time, so as to ensure that the templates assembled for the second time are the same as the first time. In addition, when the workers assemble the templates for the second time, they must repeatedly adjust the template posture to completely align the holes on the back of the template.

[0014] 6. When assembling the polymer alloy formwork at the internal corner of the structure, workers need to insert the nut into the screw and then use a wrench to tighten the nut. Since it is very inconvenient to reach out at the internal corner, it is very strenuous for workers to bend over for a long time to install the nut. Summary of the invention

[0049] Example: Figures 1 to 8 As shown, the polymer alloy template connector in this embodiment is used to realize the assembly between two spliced ​​polymer alloy templates 1. The polymer alloy template 1 has a template back rib 2 for installation, and the template back rib 2 protrudes from the back of the polymer alloy template 1.

[0050] The polymer alloy template connector in this embodiment has the following processing steps and assembly process. This embodiment describes the structure of the connector in combination with its processing steps and assembly process, as follows:

[0051] Connector processing steps:

[0052] 1) According to the construction requirements, i.e. the assembly requirements of the polymer alloy template, the outer dimensions of the lock box 4 and the buckle box 5 and the specific installation positions on the polymer alloy template 1 are determined. The lock box 4 and the buckle box 5 constitute the connector in this embodiment. According to the determined connector dimensions and specific installation positions, the connector installation groove 3 is cut on the template back rib 2 of the polymer alloy template 1, i.e. the lock box 4 is installed in the installation groove 3 of one of the two spliced ​​polymer alloy templates, and the buckle box 5 is installed in the other.

[0053] 2) According to the determined size of the connector, select square steel of appropriate size for processing the connector lock box 4 and buckle box 5, cut the square steel into several small pieces, and use a lathe to cut the inner and outer frames of the lock box 4 and buckle box 5 from each square steel. The lock box outer frame 8 and the buckle box outer frame 10 need to be chamfered to prevent the construction workers from being cut during on-site installation. Select appropriate rectangular bars and cut the bars into several small pieces according to the size of the buckle box outer frame 10. These small pieces are the buckle blocks 11 that need to be installed on the buckle box 5. The buckle blocks 11 are welded to the buckle box outer frame 10, and holes are drilled on the lock box inner frame 7 as the lock rod installation holes 12. At this point, the processing of the lock box 4 and the buckle box 5 is completed.

[0054] 3) Select a thin steel bar and cut it into several sections as needed. The outer diameter of each section of the steel bar is preferably processed to just pass through the locking rod mounting hole 12. The processed section of the steel bar is used as the locking rod end mounting rod 16. Select a steel bar of appropriate size, the outer diameter of which is slightly smaller than the internal space of the lock box inner frame 7. Cut the steel bar into several sections, drill holes on the upper side of each section of the steel bar, and the diameter of the holes is preferably slightly larger than the locking rod end mounting rod 16. Drill a threaded hole on one side section of the steel bar, and the processing of the locking rod end 15 is completed. Select a steel bar with an outer diameter smaller than the locking rod end 15, and process it into the shape shown in the figure. The thread size of one end is required to match the internal thread of the locking rod end 15, so that the locking rod end shaft 17 is processed. Process a round rod slightly thinner than the locking rod end shaft 17 as the plug 24. Next, a spring shaft 22 with a spring 21 is processed. A steel bar of suitable size is selected, one end is processed into an arc and a hole is drilled in the center of the arc. The diameter of the hole matches the plug pin 24. The other end is processed into a slightly thin round rod. A thread is drilled in the center of the end of the round rod. The processing of the spring shaft 22 is completed. A round steel bar with an outer diameter slightly larger than the spring shaft 22 round rod is selected, and one end of the round steel bar is processed into a slender thread. The thread should match the thread at the end of the spring shaft 22. The processing of the spring shaft anti-drop block 23 is completed. A long steel bar with the same outer diameter as the lock rod end 15 is processed, and the steel bar is cut into three sections, one long and two short. The long section of the steel bar is processed first, and the two ends are first processed with a lathe to make threads, and a slightly deeper hole is drilled at one end. In this way, the processing of the lock rod end connecting rod 18 is completed. Take one of the short steel bars, drill a hole in it according to the thread size of the lock rod end shaft 17, and then turn a matching thread in it according to the external thread of the un-drilled end of the long steel bar, thus completing the processing of the connecting rod shaft sleeve 19. Take another short steel bar, drill a hole in the center axis of this short steel bar according to the size of the spring shaft 22 round bar, and then turn a matching thread in it according to the external thread of the drilled end of the long steel bar, thus completing the processing of the connecting rod spring shaft sleeve 20. At this point, the lock rod connecting component 13 is completed.

[0055] 4) Select a steel pipe with a square cross section and cut it into several sections as needed. Each section is rounded along the longitudinal direction. Take one section of the steel pipe, except for the end that retains a certain thickness, the rest of the part is ground into a round rod with a lathe, and a threaded hole is drilled at the end of the round rod with a lathe, so that the processing of the extension rod 27 is completed. Select a small section of round steel with an outer diameter slightly larger than the round rod of the extension rod 27. Grind one end of the round steel into a threaded rod with a lathe, and the size of the threaded rod matches the thread at the end of the round rod of the extension rod 27, so that the extension rod anti-dropping block 28 is made. Cut a piece of square steel of a certain thickness, drill a hole in the middle of the square steel, the inner diameter of which should be larger than the outer diameter of the round rod of the extension rod 27 and smaller than the outer diameter of the extension rod anti-dropping block 28, so that the extension rod lock cover 29 is made. Select a section of round steel of appropriate size as the buckle rod 30. At this point, all the lock rod handle components are processed. A section of chamfered square steel is selected, a rectangular groove is cut out of one end of the square steel, and a small hole is drilled on the remaining two sides of the end according to the size of the plug pin 24 as the plug pin hole 26, and a deeper hole is drilled on the other end, the inner diameter of the hole is slightly larger than the outer diameter of the extension rod anti-dropping block, and the depth of the hole is greater than the round rod length of the extension rod 27. In this way, the processing of the lock rod handle component 14 is completed.

[0056] Connector installation steps:

[0057] 1) Assemble the lock rod connecting component 13 first, insert the connecting rod shaft sleeve 19 into the screw of the lock rod end shaft 17, then screw the screw of the lock rod end shaft 17 into the lock rod end 15, and screw the connecting rod shaft sleeve 19 into the lock rod end connecting rod 18. Insert the connecting rod spring shaft sleeve 20 into the spring shaft 22, then insert the spring 21 into the spring shaft 22, install the spring shaft anti-drop block 23, and screw the connecting rod spring shaft sleeve 20 into the lock rod end connecting rod 18. At this point, the assembly of the lock rod connecting component 13 is completed.

[0058] 2) Assemble the lock rod handle component 14 again. First, insert the extension rod lock cover 29 into the extension rod 27, then screw the screw of the extension rod anti-drop block 28 into the extension rod 27, and then insert the extension rod 27 into the lock rod handle 25. Apply metal glue on one side of the extension rod lock cover 29, and stick the extension rod lock cover 29 to the end of the lock rod handle 25. Weld the buckle rod 30 to the end of the lock rod handle 25 and polish it smooth. At this point, the assembly of the lock rod handle component 14 is completed.

[0059] 3) Insert one end of the spring shaft 22 of the lock rod connecting component 13 into the rectangular groove at the end of the lock rod handle component 14, and insert the plug pin 24. Insert the lock rod 6 into the lock box 4, and insert the lock rod end mounting rod 16 from the lock rod mounting hole 12. At this point, the installation of all the components of the lock box is completed.

[0060] When the connector is installed, the following steps are included:

[0061] 1) According to the size of the lock box inner frame 7 and the buckle box inner frame 9, cut the connector installation groove 3 on the template back rib 2 of the polymer alloy template 1. Install the lock box 4 and the buckle box 5 in the connector installation groove 3 in a staggered manner, that is, the lock boxes 4 should not be all installed on the same side of the template back rib 2.

[0062] 2) After the two polymer alloy templates 1 are aligned and roughly spliced, rotate the lock rod 6 in the lock box 4 and rotate the lock rod 6 toward the buckle box inner frame 9. After the lock rod 6 rotates about 90 degrees, the lock rod 6 will be restricted by the wall of the buckle box inner frame 9 and will not continue to rotate. Use force to bend the lock rod handle 25. The end of the lock rod handle 25 will pull the end of the spring shaft 22 during the bend process, thereby compressing the spring 21. When the lock rod handle 25 is bent to 90 degrees, the spring 21 is in a compressed state, which will cause the lock rod handle 25 to generate an extrusion force on the polymer alloy template 1. Slide out the extension rod 27 of the lock rod handle 25 and stretch it. Hold the extension rod 27 and bend it inward. If the two polymer alloy templates 1 are not completely aligned when spliced, the force of bend the lock rod handle 25 will align the polymer alloy templates 1 to ensure the assembly accuracy of the polymer alloy template 1. After the polymer alloy template 1 is aligned, the lock rod handle 25 will be parallel to the template back rib 2 of the polymer alloy template 1. Lift the extension rod 27 to rotate the lock rod handle 25 in a plane perpendicular to the polymer alloy template 1, so that the buckle rod 30 buckles the buckle block 11 on the side of the buckle box 5, and the assembly of the polymer alloy template 1 is completed.

[0063] 3) When removing the polymer alloy template 1, it is only necessary to rotate the lock rod handle 25, and the buckle rod 30 will be disengaged from the buckle block 11. Then the lock rod 6 is rotated back into the lock box 4 to complete the removal of the polymer alloy template 1.

[0064] This embodiment has the following characteristics during use:

[0065] 1) The connectors (lock box 4 and buckle box 5) of the polymer alloy template 1 are installed on the polymer alloy template during the factory production stage, and the installation position of the connectors is determined according to the design requirements, so that the connector positions of the polymer alloy templates are standardized. In actual use, as long as they are the same type of polymer alloy templates, the connectors of the two polymer alloy templates can be aligned, that is, the polymer alloy template equipped with the lock box 4 can be spliced ​​with any corresponding polymer alloy template equipped with the buckle box 5, which is convenient for the implementation of assembly construction, and there is no need to match the polymer alloy templates one by one.

[0066] 2) The lock box 4 and the buckle box 5 of the polymer alloy template are connected by a lock rod 6. The lock rod 6 is built into the lock box 4, and one end of the lock rod 6 is connected to the lock box 4 and can rotate. The inner cavity of the buckle box 5 is larger than the size of the lock rod 6. As long as the polymer alloy template 1 where the lock box 4 is located is roughly aligned with the polymer alloy template 1 where the buckle box 5 is located, the lock rod 6 can be easily inserted into the buckle box 5 by rotating it, which is convenient for assembly.

[0067] 3) After the locking rod 6 is inserted into the buckle box 5, the construction personnel slightly forcefully bend the handle 14 of the locking rod, the locking rod handle 14 is perpendicular to the locking rod end connecting rod 18, extend the handle extension rod 27, hold the extension rod 27 and forcefully bend it toward the buckle box 5. The buckle box 5 is subjected to the thrust of the locking rod 6, which will further align the polymer alloy template 1 where the buckle box 5 is located with the polymer alloy template 1 where the lock box 4 is located, ensuring the assembly accuracy. When the two polymer alloy templates 1 are aligned, the locking rod 6 is exactly perpendicular to the lock box 4, the locking rod end 15 cannot continue to rotate, and the locking rod 6 cannot apply thrust to the buckle box 5.

[0068] 4) The connectors on the polymer alloy template 1 are used in pairs and staggered, that is, the lock box 4 and the buckle box 5 on the back edge of a polymer alloy template 1 are installed alternately. This arrangement allows the two spliced ​​polymer alloy templates 1 to be accurately aligned under the thrust of the lock rod 6.

[0069] 5) A spring 21 is provided in the lock rod handle 14 of the connector. When the handle is bent, the spring 21 is compressed, causing the bent handle 14 to exert an extrusion force on the buckle box. This extrusion force prevents the two polymer alloy templates 1 from loosening after being spliced.

[0070] 6) The locking rod 6 can rotate 360 ​​degrees at the end of the lock box 4, so that the locking rod handle 14 can also rotate in the plane perpendicular to the polymer alloy template after being bent. The locking rod has a buckle rod 30, which buckles the buckle block 11 on the outer frame of the buckle box 5, so that the locking rod 6 will not loosen without a large external force, ensuring that the lock box 4 and the buckle box 5 are tightly connected.

[0071] 7) When removing the polymer alloy template, it is only necessary to pry the lock rod handle extension rod 27 to disengage the buckle rod 30 from the buckle block 11 for easy disassembly; at the same time, the lock rod 6 can be easily turned back into the lock box 4 by rotating it, so that the lock rod 6 is protected by the inner cavity of the lock box 4 to avoid damage during subsequent transportation.

[0072] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described one by one here.
