Description

[0001] The invention relates to the technical field of building construction, and in particular to a fiber-reinforced ultra-light cement disassembly-free formwork structure and a wall structure. Background Art

[0002] Non-disassembly formwork is a new type of building component. After the concrete structure is poured, the non-disassembly formwork does not need to be removed and can be used as part of the structure. The use of non-disassembly formwork improves working conditions, saves labor for formwork support and removal, and speeds up construction progress. Non-disassembly formwork is usually prefabricated in the factory, with a high surface smoothness, which can significantly improve the facade effect of the structure.

[0003] When installing the non-dismantling formwork, the construction technology and support form of the wooden formwork are still used. The non-dismantling formwork is punched and fixed with tension bolts. The installation process of tension bolts and primary and secondary corrugated steel pipes still requires a large number of cumbersome support and dismantling procedures, which does not significantly reduce the corresponding construction workload. The installation accuracy and stability are also low, and the outer surface of the non-dismantling formwork is damaged. Moreover, the simple bolt connection and fixation cannot adjust the internal space of the formwork.

It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Reference Figures 1 to 7 As shown, the present invention provides a fiber-reinforced ultra-light cement non-disassembly formwork structure, comprising: a non-disassembly formwork 1, a tie rod assembly 2, and a locking rod device 3.

[0037] In this embodiment, the number of the molds that do not need to be removed is two. The two molds that do not need to be removed 1 are arranged opposite to each other. A post-casting space is formed between the two molds that do not need to be removed 1.

[0038] Specifically, each side of the mold-free panel 1 includes a plurality of unit panels 11 spliced ​​together. The unit panels 11 have two adjacent sides opposite to each other. In this embodiment, each unit panel is rectangular. The unit panel has two pairs of adjacent sides. One adjacent side is formed with a socket. The other adjacent side is formed with a plug-in convex rib 12. The plug-in convex rib 12 is inserted into the socket of the adjacent unit panel 11.

[0039] An embedded component 13 is embedded in the inner side surface of the unit plate 11 .

[0040] See also Figure 1 and Figure 5 As shown, the pull rod assembly 2 includes a sleeve 21 and an insertion 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 13 on the unit board 11 arranged opposite to each other.

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

[0043] Specifically, the sleeve 31 is coaxially connected to one end of the sleeve 21. The sleeve 31 can be movably sleeved on one end of the insertion rod 22. Through grooves are formed on opposite sides of the insertion rod 22. The through groove is arranged along the axial direction of the insertion rod 22. The inner wall of the sleeve 31 is provided with an accommodating blind hole. The accommodating blind hole is aligned with the through groove. A locking block 34 is movably arranged in the orifice of the accommodating blind hole. One side of the locking block 34 is inserted in the through groove. The sleeve 31 is provided with a through hole. The through hole is arranged between the two accommodating blind holes. A slide groove is connected between the through hole formed in the cylinder wall of the sleeve 31 and the accommodating blind hole. The driving arc rod 32 is slidably arranged in the slide groove. The slide groove is arc-shaped, and the curvature of the slide groove is adapted to the curvature of the driving arc rod.

[0044] In this embodiment, the curvature of the driving arc rod is adapted to the curvature of the wall of the sleeve. The driving arc rod moves along the circumferential direction of the sleeve. One end of the driving arc rod 32 extends into the through hole. The two accommodating blind holes and the through hole are arranged in a herringbone shape. 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 of the driving arc rod 32 to the other end of the driving arc rod 32.

[0045] The push piece 33 is movably arranged in the through hole. One end of the push piece 33 is supported between one end of the two driving arc rods 32. The outer diameter of the push piece 33 gradually increases from one end of the push piece 33 to the other end of the push piece 33. An elastic member for pressing the push piece 33 against the inner side of the sleeve 31 is installed on the sleeve 31. The elastic member presses the push piece toward the axial direction of the sleeve, so that the two driving arc rods are separated from each other, and the other end of the driving arc rod is inserted between the accommodating blind hole and the locking block to push one side of the locking block out of the orifice of the accommodating blind hole and inserted into the through groove of the insertion rod, thereby locking the insertion rod to the sleeve.

[0046] As a preferred embodiment, the through hole is in the shape of an inverted truncated cone. Specifically, the inner diameter of the through hole gradually decreases from the outer side of the sleeve 31 to the inner side of the sleeve 31. The inner opening of the through hole is larger than the outer diameter of one end of the push member 33 and smaller than the outer diameter of the other end of the push member 33. One end of the push member 33 extends to the inner side of the sleeve 31 and presses against the insertion rod 22.

[0047] In this embodiment, the push piece is in the shape of an inverted truncated cone and is adapted to the shape of the through hole. One end of the push piece extends into the inner side of the sleeve and presses against the insertion rod to lock the insertion rod. At the same time, the other end of the push piece 33 is connected to a handle 35. The handle 35 is arranged on the outer side of the sleeve 31.

[0048] When the locking of the insertion rod needs to be released, the push piece is pulled out toward the outside of the sleeve, so that the push piece is separated from the insertion rod, and at the same time, the two driving arc rods return to the slide slot, so that the locking block returns to the accommodating blind hole. Preferably, the locking block is connected to the bottom of the accommodating blind hole through a spring.

[0049] As a preferred embodiment, an anti-skid pad layer is laid on the outer side of the locking block 34. In this embodiment, the anti-skid 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 embedded component 13 includes an embedded part 131 and a screw rod 132 .

[0052] The embedded part 131 is embedded in the unit board. A plurality of annular grooves 130 are formed on the outer side of the embedded part 131. The plurality of annular grooves 130 are arranged at intervals along the length direction of the embedded part 131. The embedded part 131 is provided with threaded holes. The threaded holes are arranged along the length direction of the embedded part 131.

[0053] One end of the screw rod 132 is screwed into the threaded hole, and the other end of the screw rod 132 is connected to the other end of the insertion rod 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 rod 132. The other end of the insertion rod 22 and the other end of the sleeve 21 are respectively connected with a locking column 23. The locking column 23 is detachably inserted in the through hole.

[0055] See also Figures 1 to 8 As shown, a wall structure includes a fiber-reinforced ultra-light cement non-removable formwork structure and concrete 4. The concrete 4 is poured into the post-casting space. The concrete 4 is coated on the tie rod assembly 2.

[0056] The fiber-reinforced ultra-light cement mold-free structure of the present invention comprises two groups of mold-free components arranged at intervals, a post-casting space is reserved between the two groups of mold-free components, and the unit panels are spliced. The unit panels are fiber-reinforced ultra-light cement panels.

[0057] The dimensions of the unit panel are length × width × thickness = 1200mm × 600mm × 25mm. The panel of the unit panel in contact with the post-pouring space is roughened, and the roughening is arranged along the horizontal length of the panel. After roughening, the panel that does not need to be demolded forms a uniform concave-convex structure, and the depth of the roughened groove is about 4mm.

[0058] The unit board is designed with mother-and-child grooves all around, and the mother-and-child grooves are set along the entire length of the panel. The adjacent sides have the same structure, that is, they are all grooves (socket slots) or convex grooves (plug-in ridges). The groove cross-section is semicircular with a diameter of about 10mm.

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

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

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

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

[0063] The rod locker is designed at the end of the sleeve and is an integrated structure with the sleeve. The upper part of the rod locker is a rotating handle with an elastic part (spring) inside the handle. Rotating the handle can move the spring downward, and an inverted push piece is connected below. Rotating the handle causes the inverted push piece to move downward to lock the insertion rod.

[0064] The two sides of the locking rod device are designed with inwardly movable locking blocks, which are contacted with the inverted push pieces by driving the arc rods. The push pieces push the locking blocks downward to move inwards, clamping the insertion rods from both sides.

[0065] The locking column is welded to the head end of the sleeve and the end of the plug rod. The diameter of the locking column is 6mm and is used to connect the internal and external mold-free units.

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

[0067] In the present invention, the tie rod assembly positions and fixes the template inside the template, ensuring the integrity and beauty of the template inside and outside. At the same time, the connection structure across the two templates increases the bite force between the template and the cast-in-place part, avoiding the risk of the non-removal wall template falling off, and ensuring the service life of the non-removal template.

[0068] The fiber-reinforced ultra-light cement mold-free structure of the present invention has high assembly accuracy, good reliability, tight splicing and strong applicability.

[0069] See also Figures 1 to 8 As shown, a construction method of a wall structure according to any one of the claims comprises the following steps:

[0070] S1. Install fiber-reinforced ultra-light cement non-disassembly formwork structure.

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

[0072] Specifically, according to the size of the wall in the drawing, a collage design simulation without formwork removal is performed, and the formwork is cut in advance. The coordinate points or reference lines provided in the drawing are used for positioning. The steel bars and embedded pipelines in the wall structure are pre-tied. The first unit board of the base layer is supported at the positioning location. According to the thickness of the wall, the tie rod assembly is extended to the required length, and then the locking column at one end of the tie rod assembly is inserted into the perforation of the screw on the unit board. At the same time, the corresponding unit board is supported and the locking column at the other end of the tie rod assembly is inserted into the perforation of the screw on the corresponding unit board, so that the two unit boards are arranged oppositely, and the vertical ruler is used to measure and correct the entire process in the vertical direction. The upper unit boards are spliced ​​on the base unit boards in sequence. The unit boards should be spliced ​​in an "I-shaped" shape, and flat joints should be avoided as much as possible. Repeat the operation of the adjustable limit device for horizontal and vertical positioning without formwork removal. Wet the inside of the unit board with water, pour the wall concrete and vibrate it with a vibrator. The vibrator should avoid touching the limit device and the formwork. After pouring is completed, use a high-pressure water gun to rinse the outside of the formwork to achieve maintenance and cleaning effects.
