Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a residential finished product flue unloading structure. Background Art

[0002] In civil residential buildings, prefabricated flues are usually used in kitchens and bathrooms. The flues are constructed according to the "16J916-1 Residential Exhaust Duct (I)" method for load unloading, that is, holes are reserved during structural construction, and before the installation of the flue, drilling and embedding reinforcement methods are used. Two 12mm-14mm threaded steel bars are often used to support the unloading.

[0003] In the actual construction process, the drilling and rebar planting parts need to be parallel to the floor structure surface. Due to the limited operating space, the drilling depth is insufficient, the rebar planting quality is poor, and the flue load cannot be effectively dispersed and transferred to the floor structure, resulting in poor stress stability of the unloaded steel bars. Secondly, since the wall thickness of the finished flue is relatively thin, there are only two steel bars in contact at the stress point, the force per unit area is large, and the flue wall is easily damaged. Finally, the reserved holes in the flue exist for a long time and run through from bottom to top, which poses a large safety risk of falling objects or people falling from high altitude. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a residential finished flue unloading structure, which effectively disperses the force on the load-bearing steel bars, has good stability, reduces the breakage rate of the finished flue, improves the installation quality of the flue, prevents objects or people from falling from high altitudes, and reduces safety hazards.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model discloses a residential finished flue unloading structure, comprising a floor slab and a wall, wherein a flue opening is reserved in the floor slab, and the flue opening is provided with unloading steel bars, wherein the unloading steel bars comprise longitudinal steel bars and transverse steel bars which are arranged in a criss-cross pattern, and both ends of the longitudinal steel bars and the transverse steel bars are respectively pre-buried in the corresponding floor slab and the wall, and the longitudinal steel bars and the transverse steel bars are respectively arranged along the length direction and the width direction of the flue opening, and the number of the longitudinal steel bars and the transverse steel bars is at least three.

[0007] Furthermore, the longitudinal reinforcement is arranged above the transverse reinforcement, a finished flue is installed on the top of the longitudinal reinforcement, and the longitudinal reinforcement and the transverse reinforcement are fixedly connected at the staggered positions.

[0008] Furthermore, floor slab steel bars and wall steel bars are pre-embedded in the floor slab and the wall, respectively, and both ends of the longitudinal steel bars and the transverse steel bars are fixedly connected to the corresponding floor slab steel bars and the wall steel bars, respectively.

[0009] Furthermore, the length and width of the flue opening are a and b respectively, the diameters of the longitudinal steel bars and the transverse steel bars are d, and the lengths of the longitudinal steel bars and the transverse steel bars are b+2×15d and a+2×15d respectively.

[0010] Furthermore, the number of the longitudinal steel bars is four, and the number of the transverse steel bars is three.

[0011] Furthermore, the longitudinal steel bars and the transverse steel bars are evenly arranged along the length direction and the width direction of the flue opening, respectively.

[0012] Furthermore, the longitudinal steel bars and the transverse steel bars close to the flue opening are spaced apart from the edges corresponding to the flue opening, and the longitudinal steel bars and the transverse steel bars are spaced evenly apart.

[0013] Furthermore, each flue opening is provided with a load-relief steel bar.

[0014] Furthermore, the surfaces of the longitudinal steel bars and the transverse steel bars are both provided with a protective layer.

[0015] Furthermore, the protective layer is a paint layer.

[0016] The beneficial effects of the utility model are as follows: a residential finished flue unloading structure of the present application is used for the installation and unloading of the finished flue, and the two ends of the longitudinal steel bars and the transverse steel bars are pre-embedded in the floor slab and the wall, which can ensure the depth of the longitudinal steel bars and the transverse steel bars pre-embedded in the floor slab and the wall, and avoid the situation where the flue load cannot be effectively dispersed and transmitted to the floor structure due to limited operating space, insufficient drilling depth, shallow implantation depth, poor implantation quality, and the poor stress stability of the unloading steel bars. The load steel bars composed of the longitudinal steel bars and the transverse steel bars are effectively dispersed and transmitted to the floor structure, thereby improving the stability of the load steel bars, thereby improving the stability of the residential finished flue unloading structure and improving the installation quality of the finished flue. Among them, the number of longitudinal steel bars and transverse steel bars is at least three. The more longitudinal steel bars and transverse steel bars there are, the larger the contact force area between the finished flue and the load steel bars, which effectively increases the contact force area between the finished flue and the load steel bars. The load steel bars provide better support for the finished flue, avoiding the situation where the finished flue is damaged by the load steel bars that are supported by a small area due to the thin wall of the finished flue during installation, reducing the breakage rate of the finished flue and improving the installation quality of the finished flue.

Among them, the longitudinal steel bars 1 and the transverse steel bars 2 are perpendicular, the adjacent longitudinal steel bars 1 are arranged in parallel and at intervals, and the adjacent transverse steel bars 2 are arranged in parallel and at intervals.

[0023] A residential finished flue unloading structure based on the above structure is used for the installation and unloading of the finished flue. The two ends of the longitudinal steel bars 1 and the transverse steel bars 2 are pre-embedded in the floor 4 and the wall 5, which can ensure the depth of the longitudinal steel bars 1 and the transverse steel bars 2 pre-embedded in the floor 4 and the wall 5, avoiding the situation where the flue load cannot be effectively dispersed and transmitted to the floor structure due to limited operating space, insufficient drilling depth, shallow implantation depth, poor implantation quality, and the poor stress stability of the unloading steel bars. The load steel bars composed of the longitudinal steel bars 1 and the transverse steel bars 2 are effectively dispersed and transmitted to the floor structure, thereby improving the stability of the load steel bars, thereby improving the stability of the residential finished flue unloading structure and improving the installation quality of the finished flue. Among them, the number of longitudinal steel bars 1 and transverse steel bars 2 is at least three. The more longitudinal steel bars 1 and transverse steel bars 2, the larger the contact force area between the finished flue and the load steel bars, which effectively increases the contact force area between the finished flue and the load steel bars. The load steel bars provide better support for the finished flue, avoiding the situation in which the finished flue is damaged by the load steel bars that are supported by a small area due to the thin wall of the finished flue during installation, reducing the breakage rate of the finished flue and improving the installation quality of the finished flue. The longitudinal steel bars 1 and transverse steel bars 2 are crisscrossed to form a mesh-like unloading steel bar structure, forming a barrier to effectively prevent objects or personnel from falling from high altitudes and reduce safety hazards.

[0024] Specifically, the longitudinal reinforcement 1 is arranged above the transverse reinforcement 2, a finished flue is installed on the top of the longitudinal reinforcement 1, and the longitudinal reinforcement 1 and the transverse reinforcement 2 are fixedly connected at the staggered position.

[0027] The ends of the longitudinal reinforcement 1 and the transverse reinforcement 2 are fixedly connected to the corresponding floor reinforcement and wall reinforcement, so that the longitudinal reinforcement 1 and the transverse reinforcement 2 form an integrated structure with the floor 4 and the wall 5, thereby improving the integrity and stability of the residential finished flue unloading structure. The ends of the longitudinal reinforcement 1 and the transverse reinforcement 2 are fixedly connected to the floor reinforcement and the wall reinforcement by welding or by tying with steel wire.

[0028] The length and width of the flue opening 3 are a and b respectively, the diameters of the longitudinal steel bars 1 and the transverse steel bars 2 are d, and the lengths of the longitudinal steel bars 1 and the transverse steel bars 2 are b+2×15d and a+2×15d respectively.

[0029] The embedded depth of both ends of the longitudinal reinforcement 1 and the transverse reinforcement 2 is 15d, ensuring that the embedded depths of both ends of the longitudinal reinforcement 1 and the transverse reinforcement 2 extend into the corresponding depths of the floor 4 and the wall 5, thereby ensuring that the force of the load-bearing reinforcement is effectively dispersed and transmitted to the floor structure, improving the stability of the load-bearing reinforcement, and thereby improving the stability of the residential finished flue unloading structure.

[0030] As a possible implementation method, the number of the longitudinal steel bars 1 is four, and the number of the transverse steel bars 2 is three.

[0031] The length dimension of the flue opening 3 is greater than the width dimension of the flue opening 3, and the number of longitudinal steel bars 1 is greater than the number of transverse steel bars 2. For example, there are four longitudinal steel bars 1 and three transverse steel bars 2. The four longitudinal steel bars 1 are arranged along the length direction of the flue opening 3, and the three transverse steel bars 2 are arranged along the width direction of the flue opening 3. The number of longitudinal steel bars 1 and transverse steel bars 2 can be selected according to the specific size of the flue opening 3.

[0036] Preferably, each of the flue openings 3 is provided with unloading steel bars.

[0037] Each flue opening 3 is provided with unloading steel bars, which reduce the gravity load on the finished flue below, increase the service life of the unloading steel bars, and extend the service life of the finished flue unloading structure of the residential building.

The protective layer may be a galvanized layer or an anti-corrosion paint layer.

[0040] As an implementable embodiment, the protective layer is a paint layer.
