The ruggedized construction at a kind of concrete building plank split place
Technical field:
The utility model relates to the ruggedized construction at a kind of concrete building plank split place, belongs to concrete floor crack construction technical field.
Background technology:
Building for reinforced concrete structure, in use, may be because of reasons such as the increase of the change of house function of use, flooring service load or environment changes, cause concrete floor to surpass the normal limit of bearing capacity of design, make concrete floor produce crack, the safety that jeopardizes building.At this moment, will take reinforcement measure to available coagulation Tulou plate, in the prior art, the reinforcement measure of cracks on floor slab is a lot, and general way is newly-increased one deck concrete slab on original floor, makes it stressed with original floor.This kind way exists shortcomings such as reducing house floor height, construction works amount are big, construction period length, construction investment height.Another kind of way is new increasing steel beam or a concrete beam at the bottom of plate, reduces the span between the concrete floor, increases the bearing capacity of floor; This kind way is used more in engineering, less expensive, and still, because the not newly-increased floor seat shoulder bar of newly-increased back has been reinforced the back under the effect of load, floor can produce new crack again, and new increasing steel beam or concrete beam can influence the practicality of lower layer space.
The utility model content:
The technical problems to be solved in the utility model provides a kind of ruggedized construction simple, that save the concrete building plank split place of construction costs and construction period weak point of constructing, and can overcome the deficiencies in the prior art.
The technical solution of the utility model: it comprises the cracking concrete floor, the cracking concrete floor is positioned on beam or the wall, on at the bottom of the plate at cracking concrete building plank split place, be connected with girder steel, the girder steel two ends are connected on beam or the wall, are offering the stress release slit on the plate face of cracking concrete floor and on the corresponding decorative cover.
The width in stress release slit is 7~13mm, and the degree of depth is 40~60mm.
In the stress release slit, irritate the pitch millboard is arranged.
On the stress release slit on the decorative cover, be connected with copper bar.
Compared with the prior art, the utility model is by connecting girder steel at the bottom of the plate at cracking concrete building plank split place, the girder steel two ends are connected on beam or the wall, offering the stress release slit on the plate face of cracking concrete floor and on the corresponding decorative cover, so not only can make full use of existing floor, Liang Heqiang, avoid increasing problem of cracks again newly behind the newly-increased beam of available technology adopting, and can save construction investment, minimizing construction volume, shortening duration of a project greatly.The utility model does not also influence house floor height, attractive in appearance in addition.Irritating in the stress release slit has the pitch millboard, but filling chink like this, and influence is brought to production in the elimination slit.Clamping copper bar on the stress release slit of decorative cover can prevent the breakage of pitch millboard like this.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment: as shown in Figure 1, when when existing cracking concrete floor 1 is reinforced, on at the bottom of the plate at place, cracking concrete floor 1 crack, connect a girder steel 2 earlier, this position also can be calculated according to the intensity of cracking concrete floor 1 and be determined, girder steel 2 two ends are fixed on the beam or wall of existing building, adopt instruments such as jack, pad that girder steel 2 is held out against with at the bottom of the plate that has cracking concrete floor 1 now when girder steel is installed; (multidigit is in the cracking place) cuts a stress release slit 4 on the plate face of existing cracking concrete floor 1 and on the corresponding decorative cover 3 then, the width that discharges slit 4 is 7~13mm, the degree of depth is 40~60mm, and in discharging slit 4 usefulness pitch millboard 4 cementation of fissures, discharging being provided with of slit 4 can discharge the floor top stress at girder steel 2 places naturally, makes cracking concrete floor 1 form freely-supported at new increasing steel beam 2 places; 4 places, release slit on finishing surface layer 3 can prevent the breakage of pitch millboard like this with copper bar 5 card seams at last.
