Description

Technical Field

[0001] The utility model belongs to the technical field of building pre-buried devices, and in particular relates to a fixing structure for pre-buried pipe sleeves of floor slabs. Background Art

[0002] When a hole needs to be reserved during the construction of a structural floor, a variety of methods can generally be used, such as first measuring and locating the embedded sleeve, and then welding it to the floor steel bar to fix it; or first fixing the sleeve to the floor formwork with iron nails around the bottom, pressing a small formwork on the top, and then using iron wire to tie the iron nails and the small formwork to fix the sleeve; however, these two methods have the following defects:

[0003] (1) Easy to loosen and shift. When welding is used for fixing, the steel bars are easy to loosen during the hidden inspection and concrete pouring process, thus causing the sleeve to shift;

[0004] (2) High labor costs. The pre-buried sleeve welding construction needs to be coordinated when tying the floor slab reinforcement, and the material reuse effect cannot be achieved, which increases the cost. When the top pressing small template method is used for fixing, the connecting wire needs to be cut manually later, which increases the labor time and is inefficient.

[0005] (3) Low installation accuracy. When welding or fixing with a small template on the top, it is necessary to constantly observe whether the sleeve is offset. If the offset is found after installation, adjustment is difficult and the installation accuracy is low. Utility Model Content

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0025] like Figures 1 to 3 As shown, a preferred embodiment of the utility model provides a fixing structure for embedded pipe sleeves of floor slabs, which includes a floor formwork, an embedded sleeve, a tie wire, a fixed steel bar and a fixed steel nail. The embedded sleeve is arranged on the floor formwork, and the fixed steel nail is arranged on the inner side of the embedded sleeve and fixedly connected to the floor formwork. One end of the tie wire is connected to the fixed steel nail, and the other end of the tie wire is connected to the fixed steel bar and the fixed steel bar is tied to the upper end of the embedded sleeve. In this embodiment, one end of the tie wire is wound around the fixed steel bar, and the other end of the tie wire is wound around the fixed steel nail.

[0026] During the construction process, first measure and lay out on the floor formwork, accurately determine the contour line position of the embedded sleeve, wrap one end of the tie wire around the fixed steel nail, drive the fixed steel nail wrapped with the tie wire into the inner side of the contour line of the embedded sleeve, then place the embedded sleeve at the contour line, set the fixed steel bar at the center line of the top of the embedded sleeve, and finally wrap the other end of the tie wire tightly around the fixed steel bar; thus, through the cooperation between the fixed steel nail, the tie wire and the fixed steel bar, the close connection between the embedded sleeve and the floor formwork can be ensured, and the displacement of the embedded sleeve caused by other processes can be avoided. The fixing effect is good and the precision requirements of the reserved opening can be met. When removing the formwork, it is only necessary to separate the fixed steel nail from the floor formwork. The operation is simple, the time is short, the construction efficiency is greatly accelerated, and the disassembled components can be repeatedly repaired, and the cost is low. The utility model can avoid the loosening and displacement of the embedded sleeve, and has the advantages of convenient disassembly, high construction efficiency and high installation precision.

[0027] It can be understood that after the above process is completed, the embedded sleeve can be checked whether it is firmly fixed by gently pushing it. If there is obvious looseness, the distance between the fixing wire and the inner wall of the embedded sleeve can be adjusted to ensure the effective fixation of the embedded sleeve. In addition, during construction, after completing the contour positioning of the embedded sleeve, the fixing steel nails can be driven into the floor formwork in advance before the floor formwork is constructed, and the winding process of the fixed steel bars and the tie wire can also be carried out simultaneously with the installation process of the embedded sleeve, thereby effectively improving the construction efficiency.

[0028] Exemplarily, a center positioning portion for connection is provided in the middle of the fixed steel bar, and the center positioning portion is a recessed portion of the fixed steel bar that is recessed toward the inside of the embedded sleeve. In the present embodiment, the center positioning portion is located in the center position of the inner space of the embedded sleeve, thereby enabling the force of the tie wire to act evenly on the top of the embedded sleeve, so that the fixed steel bar can press the embedded sleeve tightly against the floor formwork, thereby avoiding displacement of the embedded sleeve due to subsequent steel bar acceptance or pouring process.

[0029] In this embodiment, a plurality of the fixing steel nails are provided, and the plurality of the fixing steel nails are evenly arranged along the circumferential direction of the embedded sleeve.

[0030] For example, Figure 3 As shown, the depth of the fixing steel nail driven into the floor formwork is from one third to one half of the length of the fixing steel nail, which can ensure the connection between the fixing steel nail and the floor formwork and facilitate the winding of the tie wire.

[0031] Specifically, Figure 2As shown, the number of turns of the tie wire wrapped around the fixed steel bar is greater than three, and the number of turns of the tie wire wrapped around the fixed steel nail is greater than three, thereby ensuring the connection strength.

[0032] Exemplarily, a fixing structure for a pre-embedded pipe sleeve of a floor slab also includes a floor slab bottom reinforcement layer and a floor slab surface reinforcement layer, wherein the floor slab bottom reinforcement layer and the floor slab surface reinforcement layer both form a protective structure on the periphery of the pre-embedded sleeve through a plurality of steel bars, thereby further limiting the pre-embedded sleeve and avoiding displacement of the pre-embedded sleeve.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
