Description

A kind of sleeper structure in the middle part of wall

Technical field

The utility model is related to the sleeper structures in the middle part of a kind of wall, belong to the hydro-structure neck in hydraulic and hydroelectric engineering Domain.

Background technology

Wall is the important component of building, its effect is load-bearing, is gone along with sb. to guard him or the compartment, wall by wall by Power situation and material are divided into load bearing wall and non-load bearing wall, are divided into solid wall, sintering hollow brick wall, empty bucket by wall structure mode Wall, composite wall etc..In the design, it is desirable that wall have enough bearing capacity and stability, should also meet heat preservation, it is heat-insulated, insulate against sound, The requirements such as fire prevention, moisture-proof, waterproof.

Powerhouse of hydropower station structure generally can be divided into three components：Superstructure, substructure and generator supporting knot Structure；Superstructure mainly includes workshop framework, each floor plate, crane girder Roof system and building enclosure etc., and substructure is main There are draft tube, spiral case and machine pier and underwater wall, pier etc..House bent frame upstream column is typically secured to head bay wall wall top, downstream row Trestle is generally fixed at the top of tail water gate pier, and workshop downstream wall uses the thick wall of one-piece casting, workshop inner wall with tail water gate pier Generally using reinforced concrete wall, wall is vertical cantilever design, and wall lower end connects with basis, upper end and plate or beam phase It connects.The moment-in-plane effect being subject to for bearing wall, generally can in the end set sleeper of wall limb plane, for suspension column with Walls internal force concentrates action point at beam-ends etc., will not generally take effective engineering measure, this just needs the section for increasing wall Size to meet the requirement of structure axial compression ratio, with the ductility of control structure, ensures the plastic deformation ability of structure and resisting for structure Collapse capacity.By the way that entire thickness of wall body is increased to be built, although this way also meets structural requirement, make Unnecessary property into quantities increases, and has also accordingly increased the duration of concreting.

A variety of methods are provided to the structure design of sleeper in the prior art, but not can effectively ensure that sleeper The collapse resistant capacity of plastic deformation ability and structure, such as Chinese patent, " a kind of existing building masonry increases sleeper structure and its applies Work method (publication number：CN103075018A, publication date：2013.5.1 sleeper structure disclosed in) ", the structure are primarily directed to The renovation program for reinforcement of sleeper structure in existing building masonry, the method for use be by the additional channel steel in wall both sides, and Being connected with through-wall bolt with batten plate makes channel steel link closely wall, and compressive pre-stress is generated to wall, forms sleeper supporting wall top lotus It carries.

Utility model content

In order to solve the above technical problems, the utility model provides the sleeper structure in the middle part of a kind of wall, wall middle part Sleeper construction method it is simple, be easily mastered, it is easy to spread, have certain practical value, ensure that the plasticity of wall The collapse resistant capacity of deformability and structure.

The utility model is achieved by the following technical programs.

Sleeper structure in the middle part of a kind of wall provided by the utility model, including wall and sleeper；The sleeper is arranged on wall In vivo, and positioned at the one side of the wall close to Liang Yuzhu；The thickness of the sleeper is less than the section long edge size of wall；It is described dark Sleeper reinforcing bar is equipped in column, wall steel bar is equipped in wall.

The quantity of the sleeper is determined according to the stress of wall.

It is mutually parallel between the sleeper.

The sleeper is arranged along vertical direction.

The section of the sleeper is one kind in regular texture, anisotropic approach or variable section structure.

The beneficial effects of the utility model are：Sleeper at suspension column within the walls and beam-ends is set, column is undertaken by sleeper The internal force and moment of flexure being transferred to beam on wall, ensure the plastic deformation ability of wall and the collapse resistant capacity of structure, can be thinned whole The thickness of a wall saves the usage amount of the materials such as walls concrete and reinforcing bar, also saves concreting and is bound with reinforcing bar Duration, add the space of lower part auxiliary power house, be the laying of equipment and the current facility for providing bigger of personnel, and construct Method is simple, is easily mastered, easy to spread, has certain practical value.

Description of the drawings

Fig. 1 is the structure diagram of the utility model；

In figure：1- walls, 2- sleeper, 11- wall steel bars, 21- sleeper reinforcing bars.

Specific embodiment

Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described, it is all The technical solution formed using equivalent substitution or equivalent transformation is all fallen within the protection domain required by the utility model.

As shown in Figure 1, the sleeper structure in the middle part of a kind of wall, including wall 1 and sleeper 2；The sleeper 2 is arranged on wall 1 It is interior, and positioned at the one side of the wall 1 close to Liang Yuzhu；The thickness of the sleeper 2 is less than the section long edge size of wall 1；It is described Sleeper reinforcing bar 21 is equipped in sleeper 2, wall steel bar 11 is equipped in wall 1.

One or more sleeper reinforcing bars 21 are equipped in the sleeper 2, the quantity of sleeper 2 is determined according to 1 stress of wall, some Position stress compares concentration, it is necessary to which very thick wall sets sleeper 2 that the thickness of entire wall 1 can be thinned, sleeper reinforcing bar 21 Improving bud grafting is bound according to the reinforcement manner of column.

The setting of sleeper reinforcing bar 21 should meet《Design of hydraulic concrete structures specification》(DL/T5057-2009) design in Structural specifications.

It is mutually parallel between the sleeper 2, wherein sleeper 2 should meet《Design of hydraulic concrete structures specification》(DL/ T5057-2009) serviceability limit state checking computations and ultimate limit states checking computations.

The sleeper 2 arranges that, such as because structure needs or space limitation, 2 section of sleeper can be regular texture along vertical direction (such as：Square, rectangle and Three-legged etc.) or anisotropic approach or variable section structure in one kind, the trend of sleeper 2 can also Not exclusively by vertical direction, wherein wall 1 should meet《Design of hydraulic concrete structures specification》(DL/T5057-2009) normally make It is checked with limiting condition checking computations and ultimate limit states.

The implementation process of the utility model is as follows：

1. it should just intend the structure sizes such as bent columns, beam, wall 1 first.

2. according to bent columns and the stressing conditions of beam, analyze and calculate suspension column and the internal force and moment of flexure of beam-ends.

3. according to the transfer principle of power, analyze and calculate wall 1 and the internal force and moment of flexure of sleeper 2.

4. according to the internal force and moment of flexure of each structure, check and adjust structure size.

5. it analyzes and calculates each structural reinforcement.

In conclusion the utility model is primarily directed to the concrete wall newly poured 1, the method for use is in wall According to the reinforcing bar inside the reinforcement manner binding sleeper 2 of column in the range of 1 stress concentration, 1 original reinforcing bar of wall is according to wall 1 Reinforcement manner is bound, and after the completion for the treatment of 1 concreting of wall, is just formd a sleeper 2 in the position that stress is concentrated, is so done Not only ensure the plastic deformation ability of structure and the collapse resistant capacity of structure, but also save the materials such as 1 concrete and rebar of wall Usage amount saves the duration of concreting and reinforcing bar binding.
