Abstract

The utility model relates to a reinforced concrete all pre-set assembly type framework-shear wall structure. The two sides of the utility model are provided with upright poles. The pole and beam are connected by connecting part. A polymer concrete wallboard is positioned between the pole and the beam. The polymer concrete wallboard, the pole and the beam are connected by the connecting part. The shear wall is in the middle of the polymer concrete wallboard, which solves the problems of the duration is long and efficiency is low of current shear wall construction. The current wall shows large rigid grads, which makes the stress concentrate easily as well the capability of shock absorption is weak and the reparation and reinforcement are inconvenient. The utility model improves the anti-bend capacity of the pole wall and makes use of the character that the damp of polymer concrete is high and the flexible module is low as well as the transformation ability is good. The wallboard and the beam are connected flexibly to reduce the rigid grade between shear wall and non shear wall part and weaken the effect of stress concentration. The shock absorption ability is distinctly improved and the harm of earthquake to the structure is lowered. Besides, the structure can be repaired easily.

Description

Steel concrete assembling framework-shear wall building structure

Technical field

The utility model relates to a kind of building engineering structure, the fully-prefabricated assembled framework of particularly a kind of steel concrete-shear wall building structure.

Background technology

Before the present utility model, existing frame shear wall structure exists following deficiency and defective:

1, the job practices of this structure or system still mainly adopts the mode of cast in situs, causes long construction period, and inefficiency does not meet the development trend and the requirement of industrialization, standardized production.

2, the harmony of framework and shear wall is difficult to control.

3, the wallboard rigidity gradient is big, very easily causes dynamical stress concentration to wreck during earthquake easily.

4, a little less than the ability of damping power consumption, can only rely on structure to resist earthquake from the mode of damage under geological process, the result makes structure suffer in various degree destruction.

5, the reparation behind the structural damage is very inconvenient with reinforcing.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, design, the fully-prefabricated assembled framework of a kind of new damping power consumption steel concrete of development-shear wall building structure.

The technical solution of the utility model is:

Steel concrete assembling framework-shear wall building structure, its major technique is characterised in that both sides have column respectively, connector connects column, beam, it between column, beam the polymer concrete wallboard, connector connects polymer concrete wallboard, column, is the shear wall wallboard in the middle of the polymer concrete wallboard.

Advantage of the present utility model and effect are:

1. post and the middle part that is located at the body of wall edge being connected of post are convenient to the assembling construction, have also strengthened the safety of connecting portion simultaneously, have improved the resistance to lateral bending ability of post wall.

2. polymer concrete is adopted at wallboard periphery position, polymer concrete damping ratio height, modulus of elasticity is low, deformability is strong characteristics have been effectively utilized, wallboard links to each other with beam column is flexible, coefficient hamony is improved, reduce the rigidity gradient at shear wall position and non-shear wall position, weakened the dynamical stress concentration effect.

3. beam, post connection change the connection of L type mild steel into by being rigidly connected, and are equivalent to apply metal damper at position of joints, and the damping of structure and ductility obtain to promote significantly.

4. integrally-built damping energy dissipation capacity obviously strengthens, and when the low-lying level earthquake takes place, only just can make structure dissolve geological process at the regime of elastic deformation internal consumption with the material damping of the polymer concrete of structure and the friction of tie-point; During the high level earthquake, the polymeric material damping, metal connecting piece plastic strain damping, shear wall damage damping will play a role successively, effectively reduce the injury of earthquake to structure.

5. very convenient to the reparation of structure, only need to change connector usually and get final product.

6. this structural system can adopt post stretching that whole (or part) structure is applied prestressing force by axially reserving prestress hole at post, beam, further improves the globality and the reliability of structure.

The specific embodiment

As shown in Figure 1, both sides are columns 2, and there are two beams 1 centre, and beam 1 is connected by angle connector 6 with column 2; Between column 2, beam 1, be polymer concrete wallboard 4, adopt groove, protuberance to carry out insertion slot type between periphery and beam 1, the column 2 around the polymer concrete wallboard 3 and is connected that column 2 passes through I shape connector 5 with 4 connections of polymer concrete wallboard simultaneously; In the middle of polymer concrete wallboard 4 is traditional shear wall wallboard 3, and polymer concrete wallboard 4 is prefabricated in factory with traditional shear wall wallboard 3.

Prefabricated panel is carried out assembling by slot connection, angle connector 6, I shape connector 5 at the scene to be connected.

The polymer that polymer concrete wallboard 4 adopts is a styrene-butadiene latex, has the effect that increases the wallboard pliability, improves the structural damping power consumption.
