Description

Technical Field

[0001] The utility model relates to the technical field of support and hanger installation, in particular to a novel support and hanger connected floor structure. Background Art

[0002] The support and hanger connection structure refers to the supporting facilities firmly connected to the building structure. It is generally composed of two or more load-bearing support rods and support plates, and is used to fix pipes, cables, air ducts or other building structures.

[0003] In the prior art, supports and hangers are generally installed by driving expansion bolts into the floor slab. Although this operation is relatively common, it still has disadvantages. First, drilling holes in the floor slab and installing expansion bolts may cause damage or weakening of the floor slab structure, especially for certain types of floor slabs (such as reinforced concrete floor slabs), this operation will affect the strength and stability of the floor slab. Secondly, the installation of expansion bolts requires a series of tedious operations such as drilling holes, cleaning holes, and placing bolts. Therefore, a large amount of time and human resources will be consumed during the construction process, which is time-consuming and labor-intensive. Moreover, the installation of expansion bolts requires ensuring the accuracy of the hole diameter and hole depth, as well as the correct installation method of the bolts, otherwise the bolts may not be installed firmly, affecting the stability of the supports and hangers. In addition, once the expansion bolts are driven into the floor slab, it is difficult or impossible to remove or adjust them again, which may cause difficulties in subsequent maintenance and renovation. In the process of drilling holes and installing bolts, vibration and noise will be generated, which will interfere with or affect the surrounding environment and personnel. Therefore, a new type of support and hanger connecting the floor slab structure is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a new type of support and hanger connecting floor structure. This structure inserts the trapezoidal nuts into the gaps between the ribs of the corrugated steel plates without destroying the structure, thereby reducing the impact on the building structure; there is no need for a series of tedious operations such as drilling holes, cleaning holes, and preventing bolts, thus saving time and human resources; and it is easy to maintain in the later stage.

[0005] The technical solution for achieving the purpose of the utility model is: a new type of support and hanger connecting floor structure, including a corrugated steel plate arranged on the floor, trapezoidal nuts are arranged at the rib gaps of the corrugated steel plate, the inner annular surface of the nut is threadedly connected with a screw, a gasket is arranged on the lower surface of the corrugated steel plate, a connecting nut is arranged under the gasket, and the connecting nut is fixed to the support and hanger connecting piece.

[0006] In some embodiments, the trapezoidal nut is trapezoidal and its cross-sectional area is adapted to the cross-sectional area of ​​the gap between the ribs of the corrugated steel sheet.

[0007] In some embodiments, the connector nut fixes the support bracket connector and the screw rod through the screw rod and the gasket.

[0008] Compared with the prior art, the utility model has the following significant advantages:

[0009] Firstly, the utility model and the connection structure only need to insert the trapezoidal nut into the gap of the corrugated steel plate during installation, and then select the angle of the screw rod. Compared with the traditional installation method, it is more convenient and does not need to damage the structure of the floor plate itself. There is no need for complicated preparation work such as drilling during installation. There is no vibration or noise during installation, which can save human resources and time. The installation is more convenient, and the absence of hard connection also makes the subsequent maintenance work easier.

[0010] Second, the utility model can reduce the impact on the structure as much as possible and improve the construction efficiency and the stability of the structure by inserting the trapezoidal nut into the gap of the corrugated steel plate to bear the load while meeting the structural requirements of the building;

[0011] The invention solves the problems of the existing method of installing expansion bolts by drilling holes in the floor slab, such as damaging the structure, consuming time and energy, complicated operation and difficult maintenance in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides a new type of support and hanger connecting floor structure through improvement. The technical solution of the utility model is:

[0020] like Figure 1-Figure 3 As shown, a new type of support and hanger connecting floor structure includes a corrugated steel plate 1 arranged on the floor, wherein the corrugated steel plate 1 here is selected to be wedge-shaped or inverted trapezoidal at the plate rib, so as to be compatible with the shape of the trapezoidal nut 2, a trapezoidal nut 2 is arranged at the plate rib gap of the corrugated steel plate 1, a screw 3 is threadedly connected to the inner ring surface of the nut, a gasket 4 is arranged on the lower surface of the corrugated steel plate 1, a connecting nut 5 is arranged below the gasket 4, and the connecting nut 5 is fixed to the support and hanger connecting piece.

[0021] In one embodiment, the trapezoidal nut 2 is trapezoidal and its cross-sectional area is adapted to the cross-sectional area of ​​the gap between the ribs of the corrugated steel plate 1. The cross-sectional shape of the gap between the ribs of the corrugated steel plate should be similar to the cross-sectional shape of the trapezoidal nut 2 so as to form a reverse support point in the direction of gravity.

[0022] In one embodiment, the connector nut 5 fixes the support bracket connector and the screw rod 3 through the screw rod 3 and the gasket 4.

[0023] The specific working method is: when the new type of support and hanger is used to connect the floor slab, first select a suitable screw rod 3 and trapezoidal nut 2 to ensure that the trapezoidal nut 2 can enter the gap between the ribs of the corrugated steel plate 1, then insert the screw rod 3 into the trapezoidal nut 2, and ensure that they are tightly connected together, insert the trapezoidal nut 2 with the screw rod 3 into the gap between the ribs of the corrugated steel plate 1 along the direction of the ribs of the corrugated steel plate 1, when the trapezoidal nut 2 is inserted into the gap, rotate the screw rod 3 ninety degrees and drive the trapezoidal nut 2 to rotate ninety degrees at the same time, at this time, due to the shape characteristics of the trapezoidal nut 2, the trapezoidal nut 2 will be stuck in the ribs, providing a stable support point in the gap between the ribs of the corrugated steel plate 1, and then install the gasket, connecting nut 5, and support and hanger in sequence to complete the installation of the entire support and hanger.
