Abstract
The invention discloses an application method for dismantling temporary supports in a brick-concrete structure wall. The application method comprises the steps that first, the surface plastering layer of a bearing brick wall to be dismantled is chiseled away, and the position of a ring beam is found out; second, according to the designed scheme, the bearing brick wall is hollowed out at certain intervals; third, the temporary supports are placed in hollowed-out holes; fourth, the bearing brick wall between the temporary supports is dismantled, and a static force nondestructive cutting mode is used for cutting off the parts, exposed at the bottom of the beam, of a supporting steel tube; fifth, the construction of increasing the section of the ring beam is conducted according to the designed scheme; sixth, after the curing strength of concrete meets the design demand, the remaining bearing brick wall is dismantled; at last, the cut parts, exposed on the bottom face of the beam, of the steel tube is subjected to preservative treatment. According to the application method for dismantling the temporary supports in the brick-concrete structure wall, the bearing brick wall is dismantled and reinforced, the construction cost and the influence range are both lowered to the minimum, and great social benefits and social benefits are created.
Description
Technical field
The present invention relates in a kind of brick mix structure because removing load-bearing brick wall, enlarging section reinforcing need be carried out to former collar tie beam, need to collar tie beam temporary support technology, be specifically related to the application process that a kind of brick mix structure body of wall removes temporary support.
Background technology
Brick mix structure removes bearing wall, and mainly adopt the mode arranging transform beams first to reinforce and demolish walls afterwards, the work plane strengthened due to load-bearing brick wall and collar tie beam overlaps, and the main method setting up steel pipe scaffold support that adopts unloads collar tie beam at present; The method construction workload is large, and limits by on-the-spot site condition, and the duration is spun out; For the interim unloading that collar tie beam enlarging section is underpinning structure beam, when special building cover structure is the semi-rigid systems such as prestressed porous plate, when unloading load-bearing brick wall, full hall support scaffolding need be set up from flooring base, transmit top load-bearing brick wall load by floor system conversion again, workload is very large and limit by field condition.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the present invention proposes the application process that a kind of brick mix structure body of wall removes temporary support, this technology can be carried out temporarily the load-bearing collar tie beam of any floor, and construction plant range effects is little, and constructing operation is convenient, greatly shortens the construction period; Effectively can solve because semi-rigid floor system damages self because stiffness by itself deficiency cannot effectively change load-bearing brick wall load, prevent first tearing load-bearing brick wall open and cause structure collar tie beam to occur excessive degree of disturbing distortion, produce destructive crack.
(2) technical scheme
Brick mix structure body of wall of the present invention removes the application process of temporary support,
The first step, cuts the surperficial rendering layer intending removing load-bearing brick wall, and finds out the position of collar tie beam;
Second step, according to the scheme of design, keep at a certain distance away and draw hole to load-bearing brick wall, dimension of opening is as the criterion needed for the width supported, height, flattens hole base plate simultaneously;
3rd step, places temporary support to drawn hole, and holds out against collar tie beam; Temporary support adopts in hot pressing seamless steel pipe and waters full plain concrete, two ends arrange end and hold steel plate and make; The end of described lower end holds below steel plate and is provided with jack; The requirement for height that the height of described hot pressing seamless steel pipe can be increased according to collar tie beam adjusts;
4th step, removes the load-bearing brick wall between temporary support; And adopt static(al) to can't harm the side of cutting
Method cuts off the supporting steel pipe part be exposed at the bottom of beam;
5th step, carries out the construction of collar tie beam enlarging section by design scheme;
6th step, after concrete curing intensity reaches designing requirement, removes remaining load-bearing brick wall;
Finally, soffit part is exposed to the steel pipe cut and carries out preservative treatment, and add the mortar cover that reinforced mesh whitewashes adequate thickness.
Further, the construction of described collar tie beam enlarging section comprises concrete interface dabbing, bar planting, reinforcing bar binding, installs template, concreting.
(3) beneficial effect
The present invention compared with prior art, it has following beneficial effect: brick mix structure body of wall of the present invention removes the application process of temporary support, by adopting the method for the interim steel pipe support of structure collar tie beam, load-bearing brick wall is removed and reinforces, its operating expenses and influence basin are all reduced to minimum, create great economic benefit and social benefit.

Detailed description of the invention
Embodiment 1:
As shown in Figure 1, brick mix structure body of wall of the present invention removes the application process of temporary support, the first step, cuts the surperficial rendering layer intending removing load-bearing brick wall 4, and finds out the position of collar tie beam 2;
Second step, according to the scheme of design, keep at a certain distance away and draw hole to load-bearing brick wall, dimension of opening is as the criterion needed for the width supported, height, flattens hole base plate simultaneously;
3rd step, places temporary support to drawn hole, and holds out against collar tie beam; Temporary support adopts in hot pressing seamless steel pipe and waters full plain concrete, two ends arrange end and hold steel plate and make; Jack 1 is installed bottom it; The requirement for height that the height of described hot pressing seamless steel pipe 5 can be increased according to collar tie beam adjusts;
4th step, removes the load-bearing brick wall between temporary support; And the method adopting static(al) to can't harm cutting cuts off the supporting steel pipe part be exposed at the bottom of beam;
5th step, carries out the construction of collar tie beam enlarging section by design scheme; The construction of described collar tie beam enlarging section comprises concrete interface dabbing, bar planting, reinforcing bar binding, installs template, concreting.
6th step, after concrete curing intensity reaches designing requirement, removes remaining load-bearing brick wall;
Finally, soffit part is exposed to the steel pipe cut and carries out preservative treatment, and add the mortar cover that reinforced mesh whitewashes adequate thickness.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
