Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an optimization system for vertical cracks at the window sill position of a fully concrete exterior wall. Background Technique
[0002] The wall is a vertical component of building physics. Generally, it does not store water, accumulate water, and is not prone to leakage.
[0003] However, in actual on-site construction, factors such as rough construction, improper material selection or poor material quality, improper user use or poor management can cause the wall to crack and leak, shortening the service life of the building.
[0004] The main reasons for wall cracks are, on the one hand, wall masonry cracks. The strength grade of the masonry mortar is too low, the type of mortar is used improperly, and the mixed mortar with inaccurate mix ratio is used for masonry, reducing the strength and the integrity of the masonry, and being prone to premature weathering and looseness; during the wall construction process, the mortar is not dense and full, or the wrong masonry method results in through joints, empty joints, and blind joints, causing cracks; during construction, there are holes left by scaffolding, through-wall pipe holes, and hook supports that are not sealed tightly, causing potential hazards. On the other hand, concrete wall cracks. When the cast-in-place wall panel is poured, the strength is insufficient, the surface of the panel has honeycombing and pitting, and is crumbly. The through-wall holes and scaffolding holes left during construction are not filled solidly or the filling material has insufficient strength, causing leakage; cracks caused by structural deformation, such as uneven settlement of the foundation, too large transverse wall spacing, no steel bars added at the stress concentration points of the wall corners, too large door and window openings, improper setting of deformation joints, etc., resulting in structural deformation cracks in the masonry wall due to insufficient strength, stiffness, and stability. At this time, for crack repair, it is necessary to manually clean out a repair groove along the crack to a certain depth, and then carry out the repair. Manually cleaning the solidified concrete is time-consuming and laborious, resulting in inconvenient crack repair. Content of the Utility Model
[0005] The utility model aims at the problems in the prior art and provides an optimization system for vertical cracks at the window sill position of a fully concrete exterior wall, which solves the problem of inconvenient repair of vertical cracks at the window sill position of the exterior wall caused by reasons such as materials and construction in the prior art.
[0006] The technical solution adopted by the utility model is as follows:
[0007] An optimization system for vertical cracks at the window sill position of a fully concrete exterior wall includes a horizontally arranged connecting plate, and two vertically arranged templates are provided on the connecting plate. The two templates are used to be placed below both sides of the window sill before the exterior wall is poured. By setting the templates, a groove can be formed at the intersection position of the exterior wall and the window sill when pouring the exterior wall, so that the stress of the concrete is released at this groove, reducing the probability of crack generation. Even if there is cracking, after the stress release is completed, the groove part is subjected to hanging mesh and plastering treatment, and the crack repair work can be quickly completed.
[0008] Preferably, the cross-sectional area of the formwork is an isosceles trapezoid, and the short side of the cross-sectional area of the formwork is arranged away from the connecting plate. By setting the cross-sectional area of the formwork as an isosceles trapezoid, it can adapt to the deformation caused by large stress release, and avoid the problem that it is inconvenient to carry out subsequent hanging net and plastering treatment work due to the narrow outer side and wide inner side of the groove after the stress release is completed.
[0009] Preferably, there are two connecting plates, and both of the two connecting plates are connected to the two formworks. By providing the two connecting plates, the supporting strength for the formwork is improved.
[0010] Preferably, a supporting plate is further arranged on each connecting plate. The upper end of the supporting plate is fixedly connected to the connecting plate, and the lower end of the supporting plate is used to abut against the construction ground. By providing the supporting plate, when the connecting plate and the formwork need to be installed, one end of the supporting plate is placed on the ground, and the formwork at the other end can be vertically placed without manual assistance, which is convenient for subsequent pouring of concrete.
[0011] Preferably, a chute is formed on the side of the connecting plate close to the formwork, and a sliding block corresponding to the chute is arranged on the formwork. The sliding block is sleeved in the chute. By providing the chute and the sliding block, the formwork can move horizontally on the connecting plate to adjust the distance between the two formworks to adapt to the window sill positions with different widths.
[0012] Preferably, the formwork includes a base plate and at least one extension plate. The extension plate can be sleeved in the base plate, and the extension plate can extend vertically above the base plate. By providing the extension plate, the formwork can be placed on window sills at different heights.
[0013] It can be seen from the above technical solutions that the advantages of the present utility model are as follows: By providing the formwork, a groove can be formed at the intersection position between the outer wall and the window sill when pouring the outer wall, so that the stress of the concrete is released at this groove, reducing the probability of crack generation. Even if cracking occurs, after the stress release is completed, the groove part is subjected to hanging net and plastering treatment, and the crack repair work can be quickly completed. By setting the cross-sectional area of the formwork as an isosceles trapezoid, it can adapt to the deformation caused by large stress release, and avoid the problem that it is inconvenient to carry out subsequent hanging net and plastering treatment work due to the narrow outer side and wide inner side of the groove after the stress release is completed. By providing the two connecting plates, the supporting strength for the formwork is improved. By providing the supporting plate, when the connecting plate and the formwork need to be installed, one end of the supporting plate is placed on the ground, and the formwork at the other end can be vertically placed without manual assistance, which is convenient for subsequent pouring of concrete. By providing the chute and the sliding block, the formwork can move horizontally on the connecting plate to adjust the distance between the two formworks to adapt to the window sill positions with different widths. By providing the extension plate, the formwork can be placed on window sills at different heights. Brief Description of the Drawings

Two vertically arranged templates are provided on the connecting plate 1. The two templates are used to be placed under both sides of the window sill 8 before pouring the exterior wall 7. With this setting, through the provided templates, a groove 6 can be formed at the intersection position between the exterior wall 7 and the window sill 8 when pouring the exterior wall 7, so that the stress of the concrete is released at this groove 6, reducing the probability of crack generation. Even if cracking occurs, after the stress release is completed, the groove 6 is wired and plastered, and the crack repair work can be quickly completed.
[0025] After all the crack stresses are released, the groove 6 is plastered. The treatment of the groove 6 uses a 10*10*0.5mm wire mesh and M15 cement mortar with 3% 901 glue added for plastering. After plastering, the curing time shall not be less than 10 days.
[0026] In this embodiment, the template includes a base plate 4 and at least one extension plate 5. In this embodiment, one extension plate 5 is provided. The extension plate 5 can be sleeved inside the base plate 4, and the extension plate 5 can extend vertically above the base plate 4.
