Abstract
The utility model discloses a wall underpinning structure, comprising a structural beam, wherein a supporting device is arranged below the structural beam, two ends of the supporting device are connected with an oil wall, a new wall is arranged between the supporting device and the oil wall, the cross section of the supporting device is rectangular, and batten plates are arranged on two ends of the supporting device. The wall underpinning structure is simple in structure of required device, convenient to remove or build in site construction, short in construction period, and convenient and rapid to assemble; and then, the section height of underpinning beam can be reduced in the construction, and thus used space for reforming and underpinning is greatly improved, the cost is reduced, the underpinning process is simple, the force transmission is definite and abundant, the beam deflection is lowered, and the wall cracks are reduced.
Description
Technical field
the utility model relates to a kind of body of wall underpinning structure, belongs to technical field of building construction.
Background technology
in conventional house bottom or multistory large spaces structure construction transformation process, the method transformation that usually adopts design steel concrete at the bottom of bottom collar tie beam or plate to underpin beam underpins design.And this design and construction method needs each staged construction step must strict unified time, and before extremely easily occurring that concrete underpins beam and builds, wall body vertical degree and flaw level are abnormal for occurring, and after concreting, wall, underpin the situation that specification limits but appears exceeding in beam crack and amount of deflection.This be main because, concrete underpins beam when arranging and build, because non-homogeneity and the intensity of concrete material does not arrive design strength completely, so cause being passed to and very easily causing wall crazing while underpining beam at top body of wall load, beam deflection is excessive, cause underpining program and delay, severe patient causes interruption or the failure of wall reconstruction construction.
Summary of the invention
the purpose of this utility model be to provide a kind of simple in structure, install fast, reduce cost, safe and reliable, and can have and solve body of wall underpinning technique and the structure that current body of wall underpinning construction process is slow and body of wall easily ftractures, thereby overcome the deficiencies in the prior art.
the technical solution of the utility model
a body of wall underpinning structure, comprises structural beams, is provided with bracing or strutting arrangement below structural beams, bracing or strutting arrangement two ends and old wall connecting, and new body of wall is arranged between bracing or strutting arrangement and old body of wall.
in aforesaid body of wall underpinning structure, the width of described old body of wall is 200mm～500mm, by this scheme, old body of wall that can the disposable dismounting overwhelming majority (the old body of wall of support system below), the stable frame construction that can form by the old body of wall of part and bracing or strutting arrangement again guarantees that wall body vertical degree does not occur extremely, there will not be vertical structure beam to have seminess yet.。
in aforesaid body of wall underpinning structure, the cross section of described bracing or strutting arrangement is rectangle, and be provided with batten plate at bracing or strutting arrangement two ends, the flexural strength of the bracing or strutting arrangement of this structure is best, and by being set to an integral body, greatly improved strength and stability, by batten plate, be arranged on bracing or strutting arrangement two ends, facilitate being connected of bracing or strutting arrangement and old body of wall and structural beams, increased mutual stability.
compared with prior art, compared with prior art, the utility model is removed transformation to wall segment in building, by bracing or strutting arrangement being directly installed on to structural beams bottom in the utility model, then remove old body of wall, finally when building body of wall and bracing or strutting arrangement as being integrally formed new body of wall; The required apparatus structure of the utility model is simple, and be convenient to site operation and tear tower open, and short construction period, it is convenient to install, and then can reduce and underpin beam section height in construction, thereby significantly improve transformation, underpins usage space, reduces cost; Besides, owing to underpining beam, be steel work, when and former masonry wall between will form steel masonry compound section, can give full play to the advantage of two kinds of material complementations.Make that underpinning construction process is simple, power transmission clearly fully makes beam deflection reduce, wall body slit reduces.
Accompanying drawing explanation
accompanying drawing 1 is offered the structural representation of preformed hole for the utility model;
accompanying drawing 2 is provided with the structural representation of bracing or strutting arrangement for the utility model;
accompanying drawing 3 is provided with the structure A-A figure of bracing or strutting arrangement for the utility model;
accompanying drawing 4 for the utility model complete after structural representation.
being labeled as in accompanying drawing: 1-structural beams, 2-bracing or strutting arrangement, the old body of wall of 3-, the new body of wall of 4-, 5-batten plate, 6-slot, 7-preformed hole, 8-connecting reinforcement.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is constructed according to following a kind of body of wall underpinning technique, this technology adopts and offer preformed hole on the old body of wall of required dismounting, and this preformed hole is located at along structural beams below, preformed hole sectional dimension is than the large 10mm～30mm of bracing or strutting arrangement, then bracing or strutting arrangement is placed in preformed hole, bracing or strutting arrangement cross section is rectangle, and bracing or strutting arrangement top is connected and fixed with structural beams, below, bracing or strutting arrangement two ends is fixed with old wall connecting, progressively remove the body of wall of bracing or strutting arrangement below, but do not need to remove at the old body of wall in coupling part, two ends with bracing or strutting arrangement, the width of the old body of wall of this part is 200mm～500mm, after removing and having cleared up, reconstruct body of wall (if this body of wall is mixed clay structure, when assembling reinforcement, reinforcing bar should penetrate in the old body of wall of part, if brick wall structure, also should between old body of wall and the body of wall of construction, insert reinforcing bar, and by mortar, the wall connecting of old body of wall and construction is fixed as one), bracing or strutting arrangement (can not dismantle) forms new body of wall as a part for body of wall, in new body of wall both sides, plasters and clears up.
wherein can on the old body of wall of part, be provided with slot, the batten plate 5 on bracing or strutting arrangement can insert and in slot, realize the more stable of support system and old body of wall.
a kind of body of wall underpinning structure constructed according to technology, as shown in the figure: comprise structural beams 1, be provided with bracing or strutting arrangement 2 below structural beams 1, bracing or strutting arrangement 2 two ends are connected with old body of wall 3, the width of old body of wall 3 is 200mm～500mm, and new body of wall 4 is arranged between bracing or strutting arrangement 2 and old body of wall 3.
wherein bracing or strutting arrangement 2 can select conventional channel-section steel, i iron or H shaped steel to form the integral body that cross section is rectangle, and the size of this bracing or strutting arrangement and intensity should be formulated according to realizing field condition, at bracing or strutting arrangement 2 two ends, being provided with batten plate 5 is convenient to and being connected of brace summer 1 and old body of wall 3, at old body of wall 3, can be provided with slot 6, the batten plate 5 on bracing or strutting arrangement inserts in slot 6.
