Abstract

The invention discloses a brick wall reinforced concrete pilaster structure which includes a brick wall (1) and an old foundation (3); a cast new foundation (4) is combined with the old foundation (3); a hole is excavated on the brick wall (1); a reinforced steel bar is arranged in the hole; the reinforced steel bar is connected with the reinforced steel frames on both sides of the brick wall (1); the concrete is cast to form a reinforced concrete pilaster (5); the reinforced concrete pilaster (5) is combined with the brick wall (1). The brick wall reinforced concrete pilaster structure overcomes the defects that when the traditional method is adopted to mount a pilaster, the effective connection between the new and old masonry body structures is needed; the new and old masonry bodies is unable to have meshing effect and form an integral operating situation as a whole; the newly-added brick pilaster has insufficient intensity; the appearance and application of the building are influenced by the larger section of the reinforcing component so that the reinforced steel bar in the newly-added reinforced concrete pilaster is enabled to be tightly connected with the existed brick wall; the post-cast concrete is able to operate together with the existed masonry body wall; the integral stability and the local compression bearing capability of the wall body are improved greatly.

Description

Brick wall reinforced concrete wall stud structure

Technical field

The present invention relates to a kind of brick wall structure, this structure can improve the resistance to overturning and the local compression bearing capacity of existing brick wall to greatest extent.

Background technology

Masonry structure is as one of building structure pattern of maturation, be widely used in civilian and industrial construction in, allowable ratio of height to sectional thickness of masonry wall or column (being brick wall) is formed by mortar is bonding by monolithic brick or building block, it is one of of paramount importance vertical applied force member in the masonry structure, during when the length of brick wall and highly greater than certain numerical value, or the concentrated force that transmits of the beam of brick wall upper support is when big, for resistance to overturning or the brick wall local compression bearing capacity that guarantees brick wall can meet the demands, just need pilaster be set on brick wall according to relevant national regulation and by calculating.Therefore, whether the position is provided with pilaster in masonry structure rationally, cross-sectional sizes whether can satisfy wall stability and requirement for bearing capacity just seems particularly important, the safety that these factors will directly have influence on masonry structure whether, sometimes because design, artificial deviation appears in the construction, or the construction finish after building increased extra load again, or the height of wall is checked without authorization without design and is increased, and when finding these problems, brick wall has often been constructed and has been finished, this moment is not owing to be provided with necessary pilaster, will cause the resistance to overturning of body of wall not enough, or brick wall local compression bearing capacity can not meet the demands, if this brick wall is not carried out necessary reinforcement, will the safety of full wafer body of wall be caused a hidden trouble, even the destruction that whole building takes place, threaten the person and property safety.Generally, reinforcement measure to above-mentioned situation often is simply to increase to build brick wall stud structure by laying bricks or stones on existing brick wall, but because the not disposable fissure of displacement is built by laying bricks or stones and is formed between the old and new's masonry, therefore can't produce interlocking, so just can't form the one co-operation, newly-installed brick wall stud structure does not play corresponding effect, also easily produces the crack between the old and new's masonry, and its consolidation effect is not ideal enough.

Figure 1 shows that and adopt the full-page proof of traditional structure after setting up brick wall stud structure on the existing brick wall, (1) brick wall for having constructed and finished, (2) set up the brick wall stud structure of building by laying bricks or stones after being.As can be seen, owing to lack effective connection measure between the old and new's masonry structure, newly add between brick wall stud structure and existing brick wall and can't produce interlocking, can not form the one co-operation, also can produce the crack gradually in actual use, the effect of adding brick wall stud structure is not ideal enough.

Summary of the invention

The technical problem to be solved in the present invention is: press newly adding between brick wall stud structure and existing brick wall of existing when not enough can't produce interlocking at traditional structure solving brick wall monolithic stability or office, can not form the one co-operation, also can produce the crack gradually in actual use, the dissatisfactory weak point of reinforcing effect, a kind of new brick wall reinforced concrete wall stud structure is proposed, this structure can be set up the steel concrete pilaster easily on existing brick wall, to improve the resistance to overturning and the local compression bearing capacity of existing brick wall to greatest extent, and because component strength improves greatly, the cross section of steel concrete pilaster can reduce, and makes the building after the reinforcing more beautiful and applicable.

The present invention constitutes like this: it comprises brick wall (1), old basis (3), building new basis (4) combines with old basis (3), go up the cutting hole at brick wall (1), reinforcing bar is set in the hole, this reinforcing bar is connected with the cage of reinforcement of brick wall (1) both sides, concreting forms steel concrete pilaster (5), and steel concrete pilaster (5) combines with brick wall (1).

Going up the spacing a that digs the hole at brick wall (1) is 1000mm.

It is 120mm that width b is dug at the hole, and hole height d is 60mm.

The every side thickness e of steel concrete pilaster (5) is 100mm.

The concrete class of steel concrete pilaster (5) is not less than C20.

The invention has the beneficial effects as follows: the reinforcing bar in the newly-increased steel concrete pilaster closely is connected with existing brick wall, make the concrete and the existing allowable ratio of height to sectional thickness of masonry wall or column of after-pouring form the one co-operation, the resistance to overturning and the local compression bearing of body of wall have been improved to a greater degree, and the member section that newly adds is littler, makes building more beautiful and applicable.

Description of drawings

Fig. 2 is a structural representation of the present invention;

Fig. 3 is the C Pi sectional view among Fig. 2;

The specific embodiment

Embodiments of the invention: can carry out as follows when adopting the inventive method to set up the steel bar concrete pilaster:

The first, by calculating definite steel bar concrete pilaster 5 areas that must set up, position, quantity being set, can meet the demands to guarantee the stable and local compression of setting up the pilaster back wall;

The second, building increases the required new basis 4 of plain concrete bar base after the steel bar concrete pilaster, should be before building earlier with the plain concrete bar base basis 3 edge hackings of original brick wall 1, be beneficial to that the old and new basis is better to be connected;

The 3rd, on existing brick wall 1, dig the hole, the hole should begin to be provided with from the brick wall bottommost, and the center distance of hole on brick wall is 1m, and width is 120mm, highly is 60mm;

The 4th, in each hole, insert diameter and be 2 of the reinforcing bars of φ 8mm, the vertical applied force muscle diameter that sets up then in the concrete pilaster is φ 10mm@100, and horizontal distribution muscle diameter is φ 6mm@100;

Employing is not less than the concreting concrete pilaster and the hole cementation of fissures of C20, and the thickness of steel concrete pilaster 5 is 100mm, and width is determined by calculating.
