Abstract
The utility model relates to a kind of construction joint structure for concrete block placement, described block concrete has the backplane level with concreting, the pre-buried multiple reinforcing bar of described backplane level, it is characterized in that, the described block concrete place of be combineding with each other has the connector of fast-easy closing-up net and Steel bar rack combination, connector outer setting steel plate for sealing water, described steel plate for sealing water both sides are bent downwardly.Construction joint structure fast-easy closing-up net of the present utility model combines with Steel bar rack, carries out the separation between each section, reduces the probability that crack occurs.
Description
Technical field
The utility model relates to concrete field, particularly a kind of construction joint structure for concrete block placement.
Background technology
Concrete refer to gathered materials by cementitious matter (organic, inorganic or organo-mineral complexing), graininess, chemical admixture that water and needs add and mineral admixture be by the compound of proper proportion mixing, or after sclerosis, form the composite material (common is with cementitious material, water, fines, coarse aggregate) with heap poly structure, mix Admixture and mineral admixture when needing, coordinate by proper proportion.After concrete block placement, constuction joint position is weak link, often occurs crack, how to reduce the probability that crack occurs, becomes the problem of people.
Utility model content
In order to solve above problem, the utility model provides a kind of construction joint structure for concrete block placement reducing the probability that crack occurs.
The technical solution of the utility model is:
The utility model proposes a kind of construction joint structure for concrete block placement, described block concrete has the backplane level with concreting, the pre-buried multiple reinforcing bar of described backplane level, the described block concrete place of be combineding with each other has the connector of fast-easy closing-up net and Steel bar rack combination, connector outer setting steel plate for sealing water, described steel plate for sealing water both sides are bent downwardly.
Further, the quantity of reinforcement of described Steel bar rack is 12% ~ 18% of the quantity of reinforcement of backplane level reinforcing bar.
Further, the quantity of reinforcement of described Steel bar rack is 15% of the quantity of reinforcement of backplane level reinforcing bar.
Further, the described reclinate angle in steel plate for sealing water both sides is 30%.
Implement a kind of construction joint structure for concrete block placement of the present utility model, there is following useful technique effect:
Combine with Steel bar rack with fast-easy closing-up net, carry out the separation between each section, reduce the probability that crack occurs.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of construction joint structure for concrete block placement of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the preferred embodiment of the technical program, a kind of construction joint structure 1 for concrete block placement, block concrete 3 has the backplane level 5 with concreting, the pre-buried multiple reinforcing bar of backplane level 5, block concrete 3 place of be combineding with each other has the connector 10 of fast-easy closing-up net and Steel bar rack combination, and connector 10 outer setting steel plate for sealing water 15, steel plate for sealing water 15 both sides are bent downwardly.
Wherein, the quantity of reinforcement of Steel bar rack is 12% ~ 18% of the quantity of reinforcement of backplane level reinforcing bar.
Confirm through practice, the quantity of reinforcement of Steel bar rack is the 15% better of the quantity of reinforcement of backplane level reinforcing bar.
The reclinate angle in steel plate for sealing water 15 both sides is 30%.
Further describe in detail below.
After concrete block placement, constuction joint position is weak link, for improving constuction joint cracking resistance, increases the additional bar of floor reinforcement amount 15% at constuction joint place.Combine with Steel bar rack with fast-easy closing-up net, carry out the separation between each section.Construction of bottom plates seam place adds 3mm steel plate for sealing water, and external wall construction seam place establishes steel plate for sealing water, and variable cross-section cushion cap side adds polyphenyl cystosepiment (thick 25mm), establishes sliding layer, shrinks slip, thus reduce crack quantity for discharging overlength plate level.
Implement a kind of construction joint structure for concrete block placement of the present utility model, there is following useful technique effect:
Combine with Steel bar rack with fast-easy closing-up net, carry out the separation between each section, reduce the probability that crack occurs.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
