Description

Technical Field

[0001] This invention relates to the field of template technology, and more specifically, to a high-efficiency template splicing structure and construction method that does not require drilling. Background Technology

[0002] With the advancement of modern building construction technology (combining reinforced concrete), from traditional steel frame structures to the emerging steel formwork structures in recent years, the development and research of steel formwork structures have gradually emerged as the steel structure supporting buildings has steadily improved and progressed. Some steel formwork building support structures or building components have begun to be widely used.

[0003] Prefabricated building support structures typically consist of prefabricated support columns, beams, and floor slabs. During construction, only the modules need to be assembled, significantly improving assembly efficiency compared to traditional buildings. However, because the modules are connected through assembly, the structural strength is often insufficient, particularly the weak connections between the templates, resulting in poor overall integrity and anti-sway performance of the building support structure.

[0004] The existing patent application CN201610651806.6 discloses a floor slab splicing structure and building template. This invention relates to the field of template-type construction, providing a floor slab splicing structure and a building template including the floor slab splicing structure. In this floor slab splicing structure, the splicing sides of a first floor slab and a second floor slab are respectively erected on both sides of the lower flange of a first I-beam; a first groove is formed from the top side of the first floor slab to the splicing side, and a first connecting portion extends from the body portion of the first floor slab into the first groove; a second groove is formed from the top side of the second floor slab to the splicing side, and a second connecting portion extends from the body portion of the second floor slab into the second groove. The aforementioned patent can corroborate the deficiencies of the prior art.

[0005] Therefore, we have made improvements to this, and for this purpose, we have proposed an efficient template splicing structure and construction method that does not require drilling. Summary of the Invention

[0006] The purpose of this invention is to solve the problem of weak connection strength between templates in existing template-type building support structures.

[0007] To achieve the above-mentioned objectives, this invention provides the following efficient template hole-free splicing structure and construction method to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A high-efficiency template hole-free splicing structure includes two spaced templates, splicing plates are symmetrically arranged at both ends of the templates, and multiple through holes are opened on the splicing plates. A screw rod that penetrates the splicing plate is inserted into the through holes, and nuts are threaded to both ends of the screw rod.

The inserts can be inserted into the slots.

[0014] As a preferred technical solution of this application, two round rods are provided between the two support plates on the same side, and each support plate has a movable pin at its end. The movable pin can pass through the support plate and be inserted into one end of the round rod. The movable pin can be removed from the support plate and the round rod.

[0015] As a preferred technical solution of this application, the side surface of the support plate and the surface of the round rod are in contact with the template.

[0016] As a preferred technical solution of this application, the connecting component includes an annular groove, which is formed on a circular plate. An inner annular groove is formed inside the annular groove. The cross-section of the inner annular groove is L-shaped. Four arc-shaped pieces are slidably arranged in the inner annular groove.

[0019] As a preferred technical solution of this application, the surfaces of the two splicing plates are provided with mirror-distributed placement grooves, and the placement grooves on both sides can be combined to form a circular groove. The circular plate can be placed into the combined placement groove. The inner side of each placement groove is provided with a second protrusion, and the end face of the second protrusion is set as an arc surface. The end face of the second protrusion can press the outer wall of the circular plate in the placement groove.

[0020] A construction method for a high-efficiency template-based, hole-free splicing structure includes the following steps:

[0021] S1: Template fabrication: Based on the construction drawings and design requirements, select standard-compliant materials to fabricate wall templates;

[0022] S2: Template Installation: Before installation, clean the construction site to ensure the flatness and stability of the installation area. According to the construction drawings and design requirements, determine the installation position and elevation of the template. First, place two splicing plates according to the length of the template. Then, install four support plates inside the splicing plates on both sides. Next, install the round rod between the support plates. Then, place the template between the two splicing plates. After that, install the round plate on the four support plates. Finally, pass the screw through the hole and screw the nut in from both ends of the screw. Repeat the splicing of the splicing plates and template. After the installation is completed, reinforce the template as a whole to ensure the overall stability and safety of the template.

[0023] S3: Concrete pouring: After the formwork is installed as a whole, concrete is poured.

[0024] S4: Formwork Removal: After the concrete has hardened, remove the wall formwork step by step in the removal sequence. Clean and maintain the removed formwork for future use.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In the scheme of this application:

[0027] 1. Through the connection structure of pins and slots, the pin in the splicing plate on one side extends into the through hole of the splicing plate on the other side. Then, the rotating shaft in the splicing plate on one side is rotated, and the pin at the end of the rotating shaft rotates at a certain angle and inserts into the slot, thereby connecting the adjacent splicing plates together and making them difficult to separate. By connecting the adjacent splicing plates together, the connection strength between multiple templates is improved. During the installation process, multiple templates form a whole, improving stability and facilitating the installation work between multiple templates. At the same time, it can also eliminate the gap between adjacent splicing plates.

[0028] 2. By creating perforations in the splicing plate, drilling holes in the formwork is avoided, thus preventing damage to the overall structure of the formwork. This increases the reusability of the formwork and reduces the number of holes compared to drilling holes in the formwork. It also improves the aesthetics of the concrete wall surface, reduces the formwork loss rate, and decreases the material and labor costs for subsequent wall finishing bolts.

[0029] 3. The spacing between the two splicing panels can be adjusted according to the length of the template, which improves the adaptability of the splicing structure. During installation, the insert blocks press against the inclined surface inside the slot, which can apply pressure to the support plate, so that the splicing panels on both sides move closer to each other and clamp the template, eliminating the gap between the template and the splicing panels, making the wall surface flat and improving its aesthetics.

Detailed Implementation

[0055] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0056] Example 1, please refer to Figures 1-7A high-efficiency template-free splicing structure includes two spaced templates 1. Splicing plates 2 are symmetrically arranged at both ends of the templates 1. Multiple through holes 3 are provided on the splicing plates 2. Screws 4 are inserted through the through holes 3 and pass through the splicing plates 2. Nuts 5 are threaded to both ends of the screws 4. Two spaced through holes 9 are provided on each side of the splicing plates 2. Locking mechanisms 6 are provided in each through hole 9. An adjustment mechanism 7 is provided between the two splicing plates 2. The two ends of the adjustment mechanism 7 are connected to the locking mechanisms 6 on both sides. The adjustment mechanism 7 is connected to the splicing plates 2 on both sides through the locking mechanisms 6 on both sides. The adjustment mechanism 7 is used to adjust the distance between the two splicing plates 2.

[0057] Among them, reference Figures 6-15 The locking mechanism 6 includes an arc-shaped block 601, which is fixedly installed in the through hole 9. A rotating shaft 602 is inserted into the through hole 9. An arc-shaped groove 603 is provided at the end of the rotating shaft 602. A fan-shaped groove 604 is provided on the outer wall of the rotating shaft 602. The arc-shaped block 601 can pass through the fan-shaped groove 604 and can move within the fan-shaped groove 604. The end of the rotating shaft 602 is connected to the adjusting mechanism 7.

[0058] The ends of the rotating shafts 602 on one side are fixedly installed with arc-shaped slots 605, and the ends of the rotating shafts 602 on the other side are fixedly installed with sliding grooves 606. A pin 607 is slidably disposed in the sliding groove 606. The outer end of the pin 607 extends to the outside of the through hole 9 and is arc-shaped. The end of the pin 607 can be inserted into the slot 605. A first spring 608 is fixedly connected in the sliding groove 606. The end of the first spring 608 is fixedly connected to the pin 607.

[0059] Among them, reference Figures 16-23 The adjustment mechanism 7 includes four support plates 701 disposed between two splicing plates 2, with the four support plates 701 distributed at four corners. The end of the rotating shaft 602 is rotatably mounted on the end of the support plate 701. Each support plate 701 has multiple equally spaced slots 702. The slots 702 on the upper and lower sides are mirror-distributed. One side of the slot 702 has a bevel. One side of the template 1 has a circular plate 703. The circular plate 703 is elliptical. The circular plate 703 has a connecting component 8. The circular plate 703 has four inserts 704. The inserts 704 are rotatably mounted on the circular plate 703 through the connecting component 8 and can be inserted into the slots 702.

[0060] Two round rods 705 are hinged together between the two support plates 701 on the same side. Each support plate 701 has a movable pin 706 at its end. The movable pin 706 can pass through the support plate 701 and be inserted into one end of the round rod 705. The movable pin 706 can be removed from the support plate 701 and the round rod 705.

[0061] Among them, reference Figures 19-23The connecting component 8 includes an annular groove 801, which is formed on the circular plate 703. An inner annular groove 802 is formed inside the annular groove 801. The cross-section of the inner annular groove 802 is L-shaped. Four arc-shaped pieces 803 are slidably arranged in the inner annular groove 802. A movable block 804 is provided in the annular groove 801. The ends of the movable block 804 are respectively fixed to the insert block 704. A sleeve 805 is fixed to the arc-shaped pieces 803. A slidable movable rod 806 is inserted in the sleeve 805. The ends of the movable rod 806 are respectively fixed to the movable block 804. A second spring 807 is sleeved on the movable rod 806. The two ends of the second spring 807 are respectively fixed to the sleeve 805 and the movable block 804.

[0062] Due to the limitations of traditional construction techniques and the requirements of formwork reinforcement systems, it is necessary to drill holes in the formwork. During the formwork processing, holes are usually made on the formwork according to specific design requirements in order to install bolts, rivets and other connecting parts. This has a significant impact on the quality of the formwork itself and even its reuse, and is a reason for reducing its service life.

[0063] During installation, first place two splicing plates 2 according to the length of template 1, then install four support plates 701 in the splicing plates 2 on both sides, insert one end of the rotating shaft 602 into the through hole 9, align the arc groove 603 with the arc block 601, rotate a certain angle, and the arc block 601 rotates a certain distance in the fan groove 604, locking the rotating shaft 602 in the through hole 9, thereby installing the four support plates 701 in the splicing plates 2 on both sides. Then, install the round rod 705 between the support plates 701, and the movable pin 706 passes through the support plate 701 and inserts into one end of the round rod 705, thereby connecting the two support plates 701 at the same height through the two hinged round rods 705. Next, place template 1 between the two splicing plates 2, then install the round plate 703 on the four support plates 701, and insert the four inserts 704 into the slots 702 on the four support plates 701 respectively.

[0064] This allows the template 1 and two splicing plates 2 to be joined together. Finally, the screw 4 is passed through the through hole 3, and the nut 5 is screwed in from both ends of the screw 4. The splicing plate 2 is made from scrap material. By opening the through hole 3 in the splicing plate 2, drilling holes in the template 1 is avoided, thus preventing damage to the overall structure of the template 1. This increases the reusability of the template. Compared to drilling holes in the template 1, it reduces the number of holes, improves the aesthetics of the concrete wall, reduces the template wastage rate, and reduces the material and labor costs for subsequent wall finishing screws.

[0065] Since the spacing between the two splicing plates 2 can be adjusted according to the length of the template 1, the adaptability of the splicing structure is improved. When the four inserts 704 are inserted into the slots 702 on the four support plates 701 respectively, the inserts 704 press the inclined surfaces in the slots 702, which can apply pressure to the support plates 701, so that the support plates 701 at both ends move closer to each other. The support plates 701, the connected rotating shaft 602, and the splicing plates 2 move synchronously, so that the splicing plates 2 on both sides move closer to each other and clamp the template 1, eliminating the gap between the template 1 and the splicing plates 2, making the wall surface flat and improving the aesthetics.

[0066] When the length of template 1 changes, the four inserts 704 can be inserted into the slots 702 at different positions.

[0067] After one set of templates 1 and splicing panels 2 are installed, another set needs to be installed on the adjacent side. At this time, splicing panels 2 are placed on one side of the installed splicing panels 2. The adjacent splicing panels 2 are then connected by pins 607 and slots 605. The pin 607 in one splicing panel 2 extends into the through hole 9 of the other splicing panel 2. Then, the rotating shaft 602 in one splicing panel 2 is rotated, and the pin 607 at the end of the rotating shaft 602 rotates a certain angle and inserts into the slot 605. At this time, the first spring 608 is in its normal state, thus connecting the adjacent splicing panels 2 together and making them difficult to separate. Then, the installation of other components of this set of templates continues, and subsequent installation work is carried out in the same way. By connecting adjacent splicing panels 2 together, not only is the installation of multiple templates 1 facilitated, but the gaps between adjacent splicing panels 2 are also eliminated.

[0068] By connecting adjacent splicing panels 2 together, the connection strength between multiple templates is improved. During installation, multiple templates form a whole, which improves stability and facilitates the installation of multiple templates 1. At the same time, it can also eliminate the gap between adjacent splicing panels 2.

[0069] The sides of the support plates 701 and the surfaces of the round rods 705 are in contact with the template 1. The four support plates 701 and four round rods 705 limit one side of the template 1, increasing its strength. When concrete is poured between the templates, the middle section of the template 1 is less prone to bending, and the support strength is increased. The marking groove 14 on the rotating shaft 602 facilitates observation of its position during rotation, improving operational convenience.

[0070] Example 2 further optimizes the high-efficiency template hole-free splicing structure provided in Example 1. Specifically, as follows: Figures 19-23 As shown, multiple first protrusions 808 arranged in a circular array are fixed to the outer periphery of the annular groove 801. The end face of the first protrusion 808 is an arc surface, and the first protrusion 808 can press the end face of the movable block 804.

[0071] Because there is some adhesion between the formwork and the concrete, in order to facilitate the removal of the formwork, when the concrete is almost set, the circular plate 703 is rotated at different positions according to the actual situation. When the circular plate 703 rotates, the arc-shaped piece 803 rotates in the inner annular groove 802, and the movable block 804 rotates in the annular groove 801. During the rotation, the movable block 804 will come into contact with multiple first protrusions 808, and expansion will occur between the first protrusions 808 and the movable block 804. The first protrusions 808 will also squeeze the movable block 804, and the second spring 807 will be compressed. When the first protrusions 808 separate from the movable block 804, the elastic force of the second spring 807 when it is stretched will cause the circular plate 703 to shake. The circular plate 703 and the movable block 804 will also collide. Thus, the circular plate 703 will generate high-frequency collisions during rotation, which will be transmitted to the formwork 1 and splicing plate 2. The generated high-frequency collisions will help the formwork 1 and splicing plate 2 to detach from the wall, which will facilitate the subsequent formwork removal work.

[0072] The outer edge of the annular groove 801 is provided with a guide surface 15. The guide surface 15 is inclined to the outside and resembles a trumpet. When sound waves are generated by collision in the annular groove 801, the guide surface 15 can concentrate the sound waves and direct them more concentratedly toward the template 1, which can cause the template 1 to vibrate, thereby assisting the template 1 to detach from the wall.

[0073] The circular plate 703 has connecting holes 10 on both sides, and the end of the circular rod 705 can be inserted into the connecting hole 10. The circular plate 703 has two limiting holes 11, which are connected to the connecting holes 10 respectively, and the movable pin 706 can pass through the limiting hole 11. The two splicing plates 2 have mirror-distributed placement grooves 12 on their surfaces. The placement grooves 12 on both sides can be combined to form a circular groove, and the circular plate 703 can be placed into the combined placement groove 12. The inner side of the placement groove 12 is provided with a second protrusion 13, and the end face of the second protrusion 13 is set as an arc surface. The end face of the second protrusion 13 can press against the outer wall of the circular plate 703 in the placement groove 12.

[0074] When removing template 1, first remove the nuts 5 at both ends of screw 4, then pull out screw 4, remove the four movable pins 706, and take out the round rod 705. Two round rods 705 hinged together can form a grip. Then remove the insert block 704 from the slot opening 702, remove the round plate 703, insert one end of the grip composed of round rods 705 into the connecting hole 10, insert the movable pin 706 into the limiting hole 11 and pass through the round rod 705, so that the grip composed of round rods 705 can be connected to the round plate 10. After placing the round plate 703 into the circular groove formed by the two placement slots 12 on one side, the worker holds the handles at both ends of the round plate 703 and rotates the round plate 703. The two ends of the elliptical round plate 703 press against the second protrusions 13 on both sides, thereby applying a lateral pushing force to the splicing plate 2, which can push the splicing plate 2 and the template 1 on the side out of the wall. This demolding method is labor-saving and efficient. Then, the splicing plate 2 and the template 1 on the side are pushed out of the wall in sequence.

[0075] Example 3, please refer to Figures 1-23 A construction method for a high-efficiency template-free splicing structure includes the following steps:

[0076] S1: Template fabrication: Based on the construction drawings and design requirements, select standard-compliant materials to fabricate wall templates;

[0077] S2: Template Installation: Before installation, clean the construction site to ensure the flatness and stability of the installation area. According to the construction drawings and design requirements, determine the installation position and elevation of the template. First, place two splicing plates 2 according to the length of template 1. Then, install four support plates 701 inside the splicing plates 2 on both sides. Next, install the round rod 705 between the support plates 701. Then, place template 1 between the two splicing plates 2. After that, install the round plate 703 on the four support plates 701. Finally, pass the screw 4 through the through hole 3 and screw the nut 5 in from both ends of the screw 4. Repeat the splicing of splicing plates 2 and template 1. After installation, reinforce the template as a whole to ensure the overall stability and safety of the template.

[0078] S3: Concrete pouring: After the formwork is installed as a whole, concrete is poured.

[0079] S4: Formwork Removal: After the concrete has hardened, remove the wall formwork step by step in the removal sequence. Clean and maintain the removed formwork for future use.
