Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a fiber-reinforced ultralight cement formwork structure and wall structure that do not require dismantling. Background Art

[0002] Removable formwork is a new type of building component. After the concrete structure is poured, the formwork does not need to be removed and can be integrated into the structure. The use of removable formwork improves working conditions, saves labor for formwork erection and dismantling, and accelerates construction progress. Removable formwork is usually prefabricated in a factory, has a high degree of surface smoothness, and can significantly improve the exterior appearance of the structure.

[0003] The installation of the prefabricated formwork still employs the same construction techniques and support methods as wooden formwork, involving drilling holes in the formwork and securing it with tie bolts. The installation process for the tie bolts and main and secondary steel pipes still requires numerous and cumbersome dismantling and erection steps, failing to significantly reduce the amount of construction work. The accuracy and stability of the installation are also relatively low, and it damages the outer surface of the prefabricated formwork. Furthermore, simple bolt connections cannot adjust the internal space of the formwork; the spacing between the inner and outer formwork requires additional procedures to determine, which is cumbersome and inconvenient. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a fiber-reinforced ultralight cement formwork-free structure and wall structure are provided to solve the problem of cumbersome dismantling procedures in the existing installation process for formwork-free installation.

[0005] To achieve the above objectives, a fiber-reinforced ultralight cement formwork-free structure is provided, comprising:

[0006] Two opposing non-removable formworks are arranged, forming a post-casting space between the two non-removable formworks. The non-removable formwork includes multiple unit plates spliced ​​together. Each unit plate has two opposing adjacent sides, one adjacent side forming a receiving slot and the other adjacent side forming an insertion protrusion. The insertion protrusion is inserted into the receiving slot of the adjacent unit plate. The inner side of the unit plate is embedded with a pre-embedded component.

[0007] A tie rod assembly includes a sleeve and a rod, one end of which is movably inserted into one end of the sleeve, and the other end of the rod and the other end of the sleeve are respectively connected to a pre-embedded component on a unit plate arranged opposite to each other;

[0008] A locking rod device includes a sleeve, a driving arc rod, and a pushing component. The sleeve is coaxially connected to one end of the sleeve tube and movably sleeved on one end of the insertion rod. Through grooves are formed on opposite sides of the insertion rod, and the through grooves are arranged along the axial direction of the insertion rod. A receiving blind hole aligned with the through groove is opened on the inner wall of the sleeve. A locking block is movably disposed in the opening of the receiving blind hole, and one side of the locking block is inserted into the through groove. The sleeve has a through hole located between the two receiving blind holes. A sliding groove is formed inside the sleeve wall connecting the through hole and the receiving blind hole. The driving arc rod... The driving arc rod is slidably disposed in the sliding groove. One end of the driving arc rod extends into the through hole, and the other end extends between the bottom of the locking block and the accommodating blind hole. The outer diameter of the driving arc rod gradually decreases from one end to the other end. The pusher is movably disposed in the through hole. One end of the pusher is supported between the ends of the two driving arc rods. The outer diameter of the pusher gradually increases from one end to the other end. An elastic element is installed on the sleeve to press the pusher against the inside of the sleeve.

[0009] Furthermore, the inner diameter of the through hole gradually decreases from the outside of the sleeve to the inside of the sleeve. The size of the inner opening of the through hole is larger than the outer diameter of one end of the push member and smaller than the outer diameter of the other end of the push member. One end of the push member extends to the inside of the sleeve and presses against the insertion rod.

[0010] Furthermore, the other end of the pusher is connected to a handle, which is located on the outside of the sleeve.

[0011] Furthermore, an anti-slip pad layer is laid on the outer side of the lock block.

[0012] Furthermore, the pre-embedded component includes:

[0013] An embedded part, wherein multiple annular grooves are formed on the outer side of the embedded part, the multiple annular grooves are spaced apart along the length direction of the embedded part, and the embedded part is provided with threaded holes, which are arranged along the length direction of the embedded part;

[0014] A screw, one end of which is screwed into the threaded hole, and the other end of which is connected to the other end of the insert or the other end of the sleeve.

[0015] Furthermore, a through hole is formed at the other end of the screw, and a locking pin is connected to the other end of the insertion rod and the other end of the sleeve, respectively, and the locking pin is detachably inserted into the through hole.

[0016] This invention provides a wall structure, comprising:

[0017] Fiber-reinforced ultralight cement formwork-free structure;

[0018] Concrete is poured into the post-cast space and encapsulates the tie rod assembly.

[0019] This invention provides a construction method for a wall structure, comprising the following steps:

[0020] Install fiber-reinforced ultralight cement formwork-free structure;

[0021] Concrete is poured into the post-poured space, and the concrete covers the tie rod assembly.

[0022] The beneficial effects of the present invention are that the fiber-reinforced ultralight cement formwork-free structure of the present invention is composed of several units spliced ​​together to form a formwork-free structure. The formwork-free structure is simple, the tie rod assembly is easy to construct and operate, and the support and positioning are accurate. It can be applied to the pouring of walls of different sizes and thicknesses, and can effectively improve labor conditions and shorten the construction period.

[0023] In this invention, the tie rod assembly positions and fixes the template inside the template, ensuring the integrity and aesthetics of both the exterior and interior of the template. Simultaneously, the connection structure spanning two template sections increases the interlocking force between the template and the cast-in-place portion, avoiding the risk of the formwork falling off and ensuring the service life of the formwork.

[0024] The fiber-reinforced ultralight cement no-mold structure of the present invention has high assembly precision, good reliability, tight splicing, and strong applicability. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figures 1 to 7 As shown, the present invention provides a fiber-reinforced ultralight cement formwork structure that does not require disassembly, including: a formwork that does not require disassembly 1, a tie rod assembly 2, and a locking rod device 3.

[0037] In this embodiment, there are two non-removable molds. The two non-removable molds 1 are arranged opposite each other. A post-casting space is formed between the two non-removable molds 1.

[0038] Specifically, each non-disassembly mold 1 includes multiple unit panels 11 spliced ​​together. Each unit panel 11 has two adjacent sides. In this embodiment, each unit panel is rectangular. Each unit panel has two pairs of adjacent sides. One adjacent side forms a socket. The other adjacent side forms an insertion protrusion 12. The insertion protrusion 12 is inserted into the socket of the adjacent unit panel 11.

[0039] The inner side of the unit plate 11 is embedded with a pre-embedded component.

[0040] See Figure 1 and Figure 5 As shown, the pull rod assembly 2 includes a sleeve 21 and a plug rod 22.

[0041] One end of the insertion rod 22 is movably inserted into one end of the sleeve 21. The other end of the insertion rod 22 and the other end of the sleeve 21 are respectively connected to the embedded components on the oppositely arranged unit plate 11.

[0042] See Figures 5 to 7 As shown, the locking lever 3 includes a sleeve 31, a drive arc rod 32, and a pushing member 33.

[0043] Specifically, sleeve 31 is coaxially connected to one end of sleeve 21. Sleeve 31 is movably fitted onto one end of insertion rod 22. Through grooves are formed on opposite sides of insertion rod 22. The through grooves are arranged along the axial direction of insertion rod 22. A blind hole is provided on the inner wall of sleeve 31. The blind hole is aligned with the through groove. A locking block 34 is movably disposed in the opening of the blind hole. One side of locking block 34 is inserted into the through groove. A through hole is provided on sleeve 31. The through hole is located between two blind holes. A sliding groove is formed in the inner wall of sleeve 31, connecting the through hole and the blind hole. Drive arc rod 32 slides in the sliding groove. The sliding groove is arc-shaped, and the curvature of the sliding groove is adapted to the curvature of the drive arc rod.

[0044] In this embodiment, the curvature of the driving arc rod is adapted to the curvature of the sleeve wall. The driving arc rod moves along the circumference of the sleeve. One end of the driving arc rod 32 extends into the through hole. Two accommodating blind holes are arranged in a triangular pattern with the through hole. The other end of the driving arc rod 32 extends between the locking block 34 and the bottom of the accommodating blind hole. The outer diameter of the driving arc rod 32 gradually decreases from one end to the other.

[0045] The pusher 33 is movably disposed in the through hole. One end of the pusher 33 is supported between one end of the two drive arc rods 32. The outer diameter of the pusher 33 gradually increases from one end to the other end. An elastic element is installed on the sleeve 31 to press the pusher 33 against the inside of the sleeve 31. The elastic element presses the pusher towards the axis of the sleeve, causing the two drive arc rods to move away from each other, while the other end of the drive arc rod is inserted between the receiving blind hole and the locking block to push one side of the locking block out of the receiving blind hole and insert it into the through groove of the insert rod, thereby locking the insert rod onto the sleeve.

[0046] In a preferred embodiment, the through hole is shaped like an inverted frustum. Specifically, the inner diameter of the through hole gradually decreases from the outer side of the sleeve 31 to the inner side. The size of the inner opening of the through hole is larger than the outer diameter of one end of the pusher 33 and smaller than the outer diameter of the other end of the pusher 33. One end of the pusher 33 extends to the inner side of the sleeve 31 and presses against the insert rod 22.

[0047] In this embodiment, the pusher is shaped like an inverted frustum and is adapted to the shape of the through hole. One end of the pusher extends into the inside of the sleeve and presses against the insert rod to lock the insert rod. Meanwhile, the other end of the pusher 33 is connected to a handle 35. The handle 35 is located on the outside of the sleeve 31.

[0048] When it is necessary to release the locking of the insert rod, the pusher is pulled outward toward the outside of the sleeve, separating the pusher from the insert rod. At the same time, the two drive arc rods retract into the slide groove, causing the locking block to return to the receiving blind hole. Preferably, the locking block is connected to the bottom of the receiving blind hole by a spring.

[0049] In a preferred embodiment, the outer side of the locking block 34 is covered with an anti-slip pad layer. In this embodiment, the anti-slip pad layer is a rubber layer.

[0050] In this embodiment, the locking block is wedge-shaped.

[0051] Continue reading Figure 2 and Figure 4 As shown, the pre-embedded components include: embedded part 131 and screw 132.

[0052] The embedded part is embedded within the unit plate. Multiple annular grooves 130 are formed on the outer side of the embedded part 131. These annular grooves 130 are spaced apart along the length of the embedded part 131. The embedded part 131 has threaded holes. These threaded holes are also arranged along the length of the embedded part 131.

[0053] One end of the screw 132 is screwed into a threaded hole. The other end of the screw 132 is connected to the other end of the insert 22 or the other end of the sleeve 21.

[0054] Continue reading Figure 4 and Figure 5 As shown, a through hole is formed at the other end of the screw 132. Locking pins 23 are respectively connected to the other end of the insertion rod 22 and the other end of the sleeve 21. The locking pins 23 are detachably inserted into the through hole.

[0055] See Figures 1 to 8 As shown, a wall structure includes a fiber-reinforced ultralight cement formwork-free structure and concrete 4. Concrete 4 is poured into a post-cast space. Concrete 4 encapsulates tie rod assembly 2.

[0056] The fiber-reinforced ultralight cement formwork-free structure of the present invention includes two sets of formwork-free components spaced apart, with a post-casting space left between the two sets of formwork-free components, and is assembled from unit panels. The unit panels are fiber-reinforced ultralight cement boards.

[0057] The dimensions of the unit panel are length × width × thickness = 1200mm × 600mm × 25mm. The panel of the unit panel that is in contact with the post-pouring space is roughened. The roughening is set along the horizontal length of the panel. After roughening, the panel without demolding forms a uniform concave-convex structure. The depth of the roughened groove is about 4mm.

[0058] The unit panel features a tongue-and-groove design around its perimeter. The tongue-and-groove runs along the entire perimeter of the panel, and adjacent sides have the same structure, either grooves (slots) or protrusions (bolts). The groove cross-section is semi-circular with a diameter of approximately 10mm.

[0059] An embedded part is pre-embedded on the inner side of each unit panel.

[0060] The embedded parts are divided into two rows and are evenly embedded in the template unit along the length of the template. The upper and lower rows of embedded parts are both 75mm away from the vertical edge of the template.

[0061] The embedded part has an inner diameter of 6mm and is a hexagonal prism in the longitudinal direction. A groove structure is designed at intervals along the prism to increase the bonding ability with cement without demolding.

[0062] The pull rod assembly consists of a sleeve and a matching coaxial insert rod. The insert rod is designed with a length scale to achieve precise length adjustment. The insert rod has a V-shaped through groove on its side.

[0063] The locking lever is designed at the end of the sleeve and is an integral structure with the sleeve. The upper part of the locking lever is a rotating handle, and there is an elastic element (spring) inside the handle. Rotating the handle will cause the spring to move downward. The lower part is connected to the inverted pusher. Rotating the handle will cause the inverted pusher to move downward and lock the insertion rod.

[0064] The locking lever has inwardly movable locking blocks on both sides. The locking blocks are connected to the pusher via a drive arc rod. The pusher pushes the locking blocks downward to move inward and lock the insert rod from both sides.

[0065] The locking post is welded to the beginning of the sleeve and the end of the insertion rod. The locking post has a diameter of 6mm and is used to connect the inner and outer non-removable mold units.

[0066] The fiber-reinforced ultralight cement formwork-free structure of the present invention is composed of several units spliced ​​together to form a formwork-free structure. It is simple to formwork-free, the tie rod assembly is easy to construct and operate, and the support and positioning are precise. It can be applied to the pouring of walls of different sizes and thicknesses, and can effectively improve labor conditions and shorten the construction period.

[0067] In this invention, the tie rod assembly positions and fixes the template inside the template, ensuring the integrity and aesthetics of both the exterior and interior of the template. Simultaneously, the connection structure spanning two template sections increases the interlocking force between the template and the cast-in-place portion, avoiding the risk of the formwork falling off and ensuring the service life of the formwork.

[0068] The fiber-reinforced ultralight cement no-mold structure of the present invention has high assembly precision, good reliability, tight splicing, and strong applicability.

[0069] See Figures 1 to 8 As shown, a construction method for a wall structure as described in any one of the claims includes the following steps:

[0070] S1. Install fiber-reinforced ultralight cement formwork structure that does not require dismantling.

[0071] S2. Pour concrete 4 into the post-poured space, and the concrete 4 covers the tie rod assembly 2.

[0072] Specifically, based on the dimensions of the wall in the drawings, a no-removal formwork assembly design simulation is performed, and the template is pre-cut. Positioning is done according to the coordinate points or baselines provided in the drawings. Reinforcing steel and embedded pipelines within the wall structure are pre-tied. At the positioning point, the first unit panel of the base layer is erected. Based on the wall thickness, the tie rod assembly is extended to the required length. Then, the locking post at one end of the tie rod assembly is inserted into the through hole of the screw on the unit panel. Simultaneously, the corresponding unit panel is erected, and the locking post at the other end of the tie rod assembly is inserted into the through hole of the screw on the corresponding unit panel, ensuring the two unit panels are positioned opposite each other. A vertical ruler is used for measurement and correction throughout the vertical direction. Upper unit panels are then sequentially spliced ​​onto the base unit panel, with the unit panels forming an "I" shape, avoiding flat butt joints as much as possible. Adjustable limiting devices are repeatedly used for horizontal and vertical positioning without formwork removal. The inside of the unit panels is wetted with water, and wall concrete is poured and vibrated using a vibrator, avoiding contact between the vibrator and the limiting device and template. After pouring, use a high-pressure water gun to rinse the outside of the formwork that does not need to be removed, in order to achieve the purpose of curing and cleaning.

[0073] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
