Description

Technical Field

[0001] The utility model belongs to the technical field of floor slab internal line pipe construction, in particular to a steel bar truss floor slab internal line pipe positioning bracket. Background Art

[0002] When pouring floor slab concrete, if the pre-buried wire pipes are not firmly fixed, the spacing of the wire pipes will be uneven, resulting in poor casting and molding effects. Sometimes the wire pipes are seriously skewed, and even damaged or broken. Therefore, it is necessary to fix the wire pipes to ensure that their positions do not deviate significantly. In the prior art, during the construction of pre-buried wire pipes, steel wire binding is usually used, that is, the wire pipes are tied to the steel bars close to them. In addition, after the floor slab construction is completed, supports and hangers are usually required under the floor slab. In order to avoid interference between the construction of the supports and hangers and the pipelines, the wire pipes should be fixed to the steel bars above as much as possible while meeting the requirements of the protective layer.

[0003] In a steel truss floor deck, upper additional reinforcement and lower additional reinforcement need to be provided. To facilitate pipeline installation, the wire tube is usually installed after the installation of the lower additional reinforcement and before the installation of the upper additional reinforcement. At this time, the upper chord steel bars have a single direction and a large spacing. The wire tube is tied to the upper chord steel bars with steel wires. On the one hand, this greatly limits the layout position of the wire tube; on the other hand, the number and layout form of the wire tubes in the floor slab are gradually diversified, and the demand for parallel and cross layout of pipelines is gradually increasing. Traditional steel wire binding is difficult to meet the diversified layout requirements of pipelines in steel truss floor decks. Utility Model Content

[0004] The utility model aims to provide a positioning bracket for inner wire pipes of a steel truss floor deck, so as to solve the problem that the traditional steel wire binding and fixing method in the above-mentioned background technology is difficult to be used for parallel and cross-arrangement of pipelines in the steel truss floor deck.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wire pipe positioning bracket in a steel truss floor deck, characterized in that it includes a support rod, a connecting portion, an adjusting rod, a mounting plate, a positioning nut and a clamping portion; the support rod is spanned between two adjacent top steel bars; the connecting portion is arranged at both ends of the support rod and connected to the top steel bars; the adjusting rod is vertically arranged below the support rod and connected to the support rod, and an external thread is arranged on the surface of the adjusting rod; one end of the mounting plate is sleeved on the adjusting rod; the positioning nut is threadedly connected to the adjusting rod, and one is arranged above and below the corresponding mounting plate; the clamping portion is arranged at the bottom of the mounting plate, and is used for clamping and fixing the wire pipe.

[0007] Furthermore, through holes are arranged at intervals on the support rod; an end is arranged on the top of the adjustment rod, and the cross-sectional size of the end is larger than the size of the through hole.

[0008] Furthermore, a locking nut is arranged on the rod body of the adjusting rod and below the corresponding supporting rod.

[0009] Furthermore, the connecting portion is made of a bendable metal material.

[0010] Furthermore, the clamping portion is a clamping hoop structure.

[0011] Furthermore, in the steel bar truss floor deck, the top steel bar is an upper chord steel bar.

[0012] Furthermore, when the wire tubes overlap in the vertical plane, two mounting plates are arranged on the adjusting rod.

[0013] Furthermore, when the wire tubes cross in a vertical plane, two mounting plates are arranged on the adjusting rod, and the two mounting plates are arranged in a staggered manner.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model provides a wire pipe positioning bracket in a steel truss floor deck, in which a support rod is arranged between the top steel bars to provide a hanging point for the wire pipe, and an adjustment rod can reasonably select an installation position according to the layout position of the wire pipe, thereby making the installation position of the wire pipe not limited by the position of the upper chord steel bars.

[0016] 2. The utility model provides a wire pipe positioning bracket inside a steel truss floor deck, and the mounting plate can be longitudinally adjusted on the adjusting rod, so that the wire pipe laying height can be flexibly selected according to the design situation. At the same time, compared with the steel bar binding, the thread adjustment can significantly improve the precision control of the wire pipe laying height.

[0017] 3. The utility model provides a wire pipe positioning bracket in a steel truss floor deck. The mounting plate on the same adjusting rod can be independently set according to the layout of the wire pipe to meet the layout requirements of overlapping or crossing the wire pipe in the vertical plane. The adjustment is simple and convenient. Under normal circumstances, the number of staggered and overlapping wire pipes does not exceed 3 layers. BRIEF DESCRIPTION OF THE DRAWINGS
