Abstract

The utility model relates to a ladder rib, which is characterized by comprising a pair of main ribs which are respectively disposed on the left side and the right side and parallel to each other and a plurality of stepping ribs which are perpendicularly and fixedly connected between the two main ribs and sequentially distributed at intervals along the extending direction of the main ribs. The stepping ribs located at the two ends and the middle of the main ribs are top mold ribs, and the stepping ribs located at other parts of the main ribs are framework ribs. The distance between end portions of the top mold ribs and the main ribs close to corresponding end portions is equal and larger than the distance between corresponding end portions of the framework ribs and the main ribs close to the corresponding end portions. The length of each top mold rib is = wall thickness - reserved wall expansion value. The ladder rib is capable of effectively avoiding deviation caused by the fact that shear wall reinforcement is affected by subsequent handling, ensures construction quality of shear walls, and also is fast and convenient in construction and strong in operability.

Description

The ladder muscle

Technical field

The utility model relates to a kind of ladder muscle.

Background technology

Shear wall structure is a kind of structure commonly used in the modern architecture; At present owing to shear wall body of wall reinforcing bar is just simply formed by the colligation of transverse reinforcement and vertical reinforcement; Therefore influenced by subsequent handling such as template installation, concreting etc., cause mass defects such as body of wall reinforcing bar off normal and protective layer thickness deficiency.Traditional job practices can only be through the operation of joining a regular shift or class of mounting reinforcing steel bars worker when the concreting; Come the reinforcing bar of off normal is corrected; Consumption worker not only consuming time; And since construction quality depend on reinforcing bar footman operating personnel sense of responsibility and with the cooperating of concreting operation, so construction quality is unstable.

Summary of the invention

In order to solve existing in prior technology the problems referred to above; The utility model provides a kind of ladder muscle, and it not only can effectively avoid shear wall body of wall reinforcing bar influenced by subsequent handling and the off normal phenomenon that produces, guarantees the construction quality of shear wall; And it is convenient to construct, workable.

The utility model technical scheme is to constitute like this; A kind of ladder muscle is characterized in that: it comprises that a pair of left and right sides and parallel each other main muscle and Duo Gen vertical fixing of being divided into is connected between two main muscle and along the main muscle bearing of trend muscle of marking time spaced apart successively; The muscle of marking time that is positioned at main muscle two ends and middle part is the backform muscle, and the muscle of marking time that is positioned at other position of main muscle is the skeleton muscle; Each end of each root backform muscle is with identical near the distance between the main muscle of respective end and greater than the respective end of each root skeleton muscle and near the distance between the main muscle of this respective end, the length=thickness of wall body of each root backform muscle-reservation body of wall swell value.

Said reservation body of wall swell value is preferably 2mm.

Colligation between ladder muscle and the shear wall body of wall reinforcing bar is for ease fixed; When the length bearing of trend level of waiting to build cavity along body of wall when the main muscle of said ladder muscle was set up, adjacent two distances between the muscle of marking time=perpendicular placed body of wall to wait to build in the cavity and wait to build the distance between the length bearing of trend of cavity two vertical reinforcements adjacent one another are along body of wall; When the height bearing of trend of waiting to build cavity along body of wall when the main muscle of said ladder muscle vertically set up, adjacent two distance=horizontal cross of marking time between the muscle were arranged at that body of wall is waited to build in the cavity and wait to build the distance between the height bearing of trend of cavity two horizontal reinforcements adjacent one another are along body of wall.

For effective control body of wall protective layer thickness, the diameter x2 of the distance=thickness of wall body-body of wall protective layer thickness-main muscle between two main muscle.

The operating principle of the utility model technique scheme is explained as follows: during construction; Can the length bearing of trend level frame that the ladder muscle waits to build cavity along body of wall be established or waits that along body of wall the height bearing of trend of building cavity vertically sets up; Making being cross-linked of the main muscle of ladder muscle and the muscle of marking time carry out colligation between position and vertical reinforcement or the horizontal reinforcement fixes; Form stable reinforced bar support structure; Prevent to build the skew that process produces, the end through the backform rod leans the location and can guarantee the thickness of wall body of building template.

Compared to prior art; The utlity model has following advantage: the utility model is simple in structure, and is easy to use, and fastness is strong; The off normal phenomenon that not only can effectively avoid shear wall body of wall reinforcing bar influenced by subsequent handling and produce; Guarantee the construction quality of shear wall, and it is convenient to construct, workable.

The specific embodiment

Below in conjunction with the Figure of description and the specific embodiment the utility model content is elaborated:

Be illustrated in figure 1 as the example structure sketch map of a kind of ladder muscle that the utility model provides, it is characterized in that: it comprises and a pair ofly is divided into the left and right sides and parallel each other main muscle 1 and the Duo Gen vertical fixing is connected between two main muscle 1 and along the main muscle 1 bearing of trend muscle of marking time spaced apart successively; The muscle of marking time that is positioned at main muscle 1 two ends and middle part is a backform muscle 2, and the muscle of marking time that is positioned at main muscle 1 other position is a skeleton muscle 3; Each end of each root backform muscle 2 is with identical near the distance between the main muscle 1 of respective end and greater than the respective end of each root skeleton muscle 3 and near the distance between the main muscle 1 of this respective end, the length=thickness of wall body of each root backform muscle 2-reservation body of wall swell value.

Said reservation body of wall swell value is 2mm.

When the length bearing of trend level of waiting to build cavity along body of wall when the main muscle 1 of said ladder muscle was set up, adjacent two distances between the muscle of marking time=perpendicular placed body of wall to wait to build in the cavity and wait to build the distance between the length bearing of trend of cavity two vertical reinforcements 4 adjacent one another are along body of wall; When the height bearing of trend of waiting to build cavity along body of wall when the main muscle 1 of said ladder muscle vertically set up, adjacent two distance=horizontal cross of marking time between the muscle were arranged at that body of wall is waited to build in the cavity and wait to build the distance between the height bearing of trend of cavity two horizontal reinforcements adjacent one another are along body of wall.

The diameter x2 of the distance=thickness of wall body-body of wall protective layer thickness-main muscle 1 between two main muscle 1.

The length of the backform muscle 2 at edge is exposed in two main muscle 1 ends can be identical or different, and when ladder muscle horizontal positioned, the length that two main muscle 1 expose can be identical; When the ladder muscle was vertically placed, the alternative shear wall vertical reinforcement of ladder muscle at this moment, according to job specfication, staggered in order to make butt joint, and the length that two main muscle 1 expose can be different.
