Abstract
The invention discloses a foundation slab post-cast concrete strip structure. The foundation slab post-cast concrete strip structure is characterized in that a groove is formed in the lower portion of a foundation slab post-cast strip. According to the design structure, the function of reducing harmful effects such as differential settlement and shrinkage of the post-cast strip is fully exerted, workers do not need to clear building rubbish and man-made rubbish through a traditional method before the post-cast strip is cast and only need to flush the rubbish into the groove in the lower portion of the post-cast strip through a high-pressure water gun, post-cast strip construction quality is guaranteed, and accordingly control over the whole building construction quality is facilitated; the investment of manpower, material resources and time in the rubbish clearing process is reduced, and therefore cost can be effectively controlled.
Description
Technical field
After the present invention relates to a kind of foundation slab, pouring concrete band is constructed, and belongs to design of reinforced concrete structure and building technology field.
Background technology
Ater-casting is for preventing that monolithic reinforced concrete structure is due to temperature in building operations, shrink uneven and the issuable harmful cracks of differential settlement, according to design or job specfication requirement, at sole plate, wall, beam relevant position is stayed and is established temporary construction seam, structure is temporarily divided into some parts, through component inside, shrink, after the some time, water again and smash this constuction joint concrete, structure is linked to be to integral body, as shown in Figure 1, on sole plate 2, stay in the temporary construction seam rear pouring concrete 1 of establishing and add expansion agent, and and the steel plate water stopper 3 of level is set between sole plate 2, between the cast-in-place enhancement Layer 4 of sole plate 2 and its underpart, waterproofing course 5 is set.Pouring after settlement is set in foundation slab and both can discharges most adverse effect, can meet again the functional requirement of building, be widely used in engineering now.Although pouring after settlement can reasonable solution differential settlement and the problem of concrete shrinkage, but the design of ater-casting and construction technology can affect the quality of ater-casting cast, even affect the use function of structure etc., and the relevant regulations disunity of standard to ater-casting, does not have detailed, complete clause design and construction both at home and abroad.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, and pouring concrete band structure after a kind of foundation slab is provided, and can reduce the input of human and material resources and time.
For solving the problems of the technologies described above, the invention provides pouring concrete band structure after a kind of foundation slab, it is characterized in that, in bottom, foundation slab ater-casting, one groove is set.
By the groove arranging, make to form between sole plate and cast-in-place enhancement Layer a reserved space.
Before ater-casting cast, by described groove, hold by giant and rush in foreign material wherein, as rubbish etc.
The beneficial effect that the present invention reaches:
(1) reduce the adverse effects such as structure differential settlement and concrete shrinkage;
(2) do not need with conventional method cleaning building waste and artificial rubbish;
(3) be conducive to the assurance of ater-casting construction quality;
(4) less human and material resources and the input of time in refuse sweeping process, effectively control cost.
Accompanying drawing explanation
Fig. 1 is the generalized section of pouring concrete band after traditional foundation slab.
Fig. 2 is the generalized section of pouring concrete band after example foundation slab of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
After foundation slab of the present invention, pouring concrete band structure as shown in Figure 2, before cast sole plate 1, is staying the temporary construction seam lower position of establishing that additional waterproof roll layer 7, cast-in-place C30 concrete enhancement Layer 4 on additional waterproof roll layer 7 are set.Arrange after a waterproofing course 5, on waterproofing course 5, build sole plate 2, on sole plate 2, stay in the temporary construction seam of establishing and pour into a mould rear pouring concrete 1, the steel plate water stopper 3 of level is set between rear pouring concrete 1 and sole plate 2.The reserved groove 6 in bottom, foundation slab ater-casting, be after foundation slab, after pouring concrete band and between cast-in-place enhancement Layer 4, to have a headspace, this design structure has not only been given full play to the effect that ater-casting reduces the adverse effects such as differential settlement and contraction, and before the cast of ater-casting, do not need with conventional method cleaning building waste and artificial rubbish, only need rubbish be flushed in lower recess 6 with giant, guarantee the construction quality of ater-casting, and then be conducive to the control of whole architecture construction quality.
Ater-casting casting process is as follows:
First lay template, stay and establish groove, assembling reinforcement is also located, and finally builds the concrete of sole plate and cast-in-place enhancement Layer.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
Claims (3)
1. pouring concrete band structure after a foundation slab, is characterized in that, in bottom, foundation slab ater-casting, one groove is set.
2. pouring concrete band structure after foundation slab according to claim 1, is characterized in that, by the groove arranging, makes to form between sole plate and cast-in-place enhancement Layer a reserved space.
