Description

Technical Field

[0001] The utility model belongs to the field of prefabricated building engineering, and particularly relates to an anti-camber fixing fixture. Background Art

[0002] The construction method for fixing the anti-camber in positions such as bathrooms and kitchens is relatively complex. Currently, the anti-camber fixing fixture uses wooden boards, and a tension rod is provided in the middle of the wooden board to provide tension, thereby fixing the anti-camber wooden formwork. Additionally, another wooden board is fixed above the anti-camber formwork to further fix the anti-camber. The following problems exist in the use of this casting mold:

[0003] Currently, the construction quality of the concrete anti-camber is poor and the construction efficiency is low. Many need to be chiseled and re-constructed later, increasing a large amount of costs. 2. Currently, the common way to fix the anti-camber is through wooden board buckles, and the wooden boards are tightened by tension rods to achieve no displacement, but the effect is poor, and problems such as form bulging, form displacement, and position deviation are likely to occur. 3. After the anti-camber is constructed using the traditional method, there will be marks of the tension rods on the upper part, and it is necessary to pour again to make the anti-camber flush. 4. And currently, the traditional anti-camber fixing fixture has a low reuse rate. Content of the Utility Model

[0004] In view of the problems such as form bulging, form displacement, and position deviation that are likely to occur in the existing anti-camber fixing fixture, an anti-camber fixing fixture is proposed. The utility model is simple to install and disassemble, easy to carry, more environmentally friendly than the existing anti-camber fixture, and has low labor costs; the fixture has a high reuse rate; and problems such as form bulging, form displacement, and position deviation are not likely to occur during the anti-camber pouring process.

[0005] To solve the above technical problems, the technical solution adopted by the utility model: An anti-camber fixing fixture includes a portal frame body. The anti-camber to be poured is located in the middle of the portal frame body. Anti-camber formworks are arranged on both sides of the anti-camber to be poured. At least one set of adjustable pushing and fixing components is arranged between each side of the anti-camber formwork and the portal frame body. A transverse tensioning device is arranged on the portal frame body at the top of the anti-camber formwork.

[0006] The portal frame body includes two longitudinal rectangular square tubes. A base is arranged at the bottom surface of the longitudinal rectangular square tubes. The tops of the two longitudinal rectangular square tubes are welded and fixed by a transverse rectangular square tube.

[0007] The pushing and fixing component includes a pressing plate and a fixing rod. One end of the fixing rod is fixedly arranged in the middle of the pressing plate. A fastening thread is arranged in the middle of the fixing rod. The other end of the fixing rod passes through the longitudinal rectangular square tube of the portal frame body, and the fixing rod and the longitudinal rectangular square tube are tightly connected by a nut.

[0008] The number of the pushing and fixing components is four groups. Two groups of adjustable pushing and fixing components are arranged between each side of the anti-camber formwork and the portal frame body, and the two pushing and fixing components are distributed longitudinally.

[0009] The horizontal tensioning device includes a horizontal steel bar sheet that can slide up and down along a longitudinal rectangular square tube. Both ends of the horizontal steel bar sheet are fixed to the longitudinal rectangular square tube through fixing clamps and bolts.

[0010] The beneficial effects of the present utility model compared with the prior art are as follows: The present utility model fixes the wooden formwork on both sides of the to-be-poured anti-cantilever through the pushing and fixing parts fixed on the gantry frame body. The pushing and fixing parts press the anti-cantilever formwork tightly, eliminating the need for setting tie bolts and avoiding the need to fill the uneven surface on the upper part of the anti-cantilever caused by the tie bolts later. Moreover, the fixing fixture of the present utility model is made of commonly used materials such as rectangular steel pipes, steel plates, and screws on construction sites, with low cost and can be reused multiple times. During the pouring process of the anti-cantilever, problems such as formwork bulging, formwork slipping, and position deviation are not likely to occur. Description of the Drawings

Detailed Embodiment

[0014] As Figure 1 shown, an anti-cantilever fixing fixture includes a gantry frame body 1, and the gantry frame body 1 is composed of two longitudinal rectangular square tubes 11 and a horizontal rectangular square tube 13. The horizontal rectangular square tube 13 welds and fixes the tops of the two longitudinal rectangular square tubes 11 together. A base 12 is provided at the bottom surface of the longitudinal rectangular square tube 11. By setting the base 12, the contact area is increased, making the gantry frame body 1 more stably supported on the bottom surface.

[0015] The to-be-poured anti-cantilever 2 is located in the middle of the gantry frame body 1. Anti-cantilever formworks 3 are provided on both sides of the to-be-poured anti-cantilever 2. At least one set of adjustable pushing and fixing parts 4 is provided between each side of the anti-cantilever formwork 3 and the gantry frame body 1. Usually, the number of the pushing and fixing parts 4 is set to four groups. Two sets of adjustable pushing and fixing parts 4 are provided between each side of the anti-cantilever formwork 3 and the gantry frame body 1. The two pushing and fixing parts 4 are distributed longitudinally, which can make the upper and lower sides of the anti-cantilever formwork 3 receive more uniform force and can effectively prevent problems such as formwork bulging, formwork slipping, and position deviation.

[0016] For the top of the anti-overflow formwork 3 where overflow is likely to occur, a transverse tensioning device 5 is provided on the gantry frame body 1 at the top of the anti-overflow formwork 3. The transverse tensioning device 5 is used to limit and tension the top of the anti-overflow formwork 3, leaving no marks of the tensioning bolts. It can be formed in one pouring and does not require secondary repair.

[0017] During use, the anti-overflow formwork 3 of the present utility model is fixed every 10 cm in sequence. After the pouring and curing are completed, the nut 43 of the push-and-fix member 4 is unscrewed, and the gantry frame body 1 can be directly lifted by hand to remove the fixture. The entire operation process is convenient and fast and can be reused.

[0018] In the above embodiments, the specific structures of the push-and-fix member 4 and the transverse tensioning device 5 are not limited, as long as they can perform the above-mentioned pressing and tensioning functions. For the convenience of those skilled in the art to better understand the present utility model, the push-and-fix member 4 and the transverse tensioning device 5 are introduced in detail in this embodiment.

[0019] The push-and-fix member 4 includes a pressing plate 41 and a fixing rod 42. One end of the fixing rod 42 is fixedly welded in the middle of the pressing plate 41. The pressing plate 41 is used to increase the contact area with the anti-overflow formwork 3, making the force more uniform. A fastening thread is provided in the middle of the fixing rod 42. The other end of the fixing rod 42 passes through the longitudinal rectangular square tube 11 of the gantry frame body 1, and the fixing rod 42 is fixedly connected to the longitudinal rectangular square tube 11 through a nut 43.

[0020] The transverse tensioning device 5 includes a transverse steel rod piece 51 that can slide up and down along the longitudinal rectangular square tube 11. Both ends of the transverse steel rod piece 51 are fixed to the longitudinal rectangular square tube 11 through fixing clips 52 and bolts 53. In addition to the above-mentioned transverse tensioning device 5, the structure of the tensioning bolt can also be applied to this position. Compared with the tensioning bolt, the bottom surface of the transverse steel rod piece 51 is flat. Even if it accidentally contacts the pouring surface, it will not damage the pouring surface and does not require secondary repair.

[0021] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model.
