Embodiment 1

[0023] The window sill topping concrete prefabricated block of the present invention comprises a window sill topping concrete prefabricated block body.

[0024] see now figure 1 and figure 2 , figure 1 It is a schematic structural diagram of the window sill topped concrete precast block according to the embodiment of the present invention, figure 2 for figure 1 side view. As shown in the figure, the window sill topping concrete precast block is 100mm thick, 250mm long, and the width is the same as the wall thickness, and the slope angle and steel bar are reserved in advance. The oblique slope angle 6 is roughened, the exposed length of the steel bar 5 is 100mm, and the anchorage length of the steel bar deep into the precast block is 200mm.

Embodiment 2

[0026] The use method of the window sill topping concrete precast block of the present invention:

[0027] image 3 It is a schematic diagram of the use state of the window sill-topped concrete precast block according to the embodiment of the present invention. After the masonry of the lower window hole 1 of the concrete lintel 2 of the wall is completed, two precast concrete blocks 3 for window sill topping are arranged correspondingly under the window hole, so as to achieve the middle topping part of the secondary pouring concrete 4, reduce the technical intermittent, and ensure that the topping is deep into the wall. The lap length meets the requirements and is controlled to be 250mm to ensure the overall masonry quality and save construction time and labor costs. The construction of masonry walls and window sills is not affected by each other, which is suitable for projects with a particularly tight construction period.

[0028] The invention has substantial features and...

Abstract

A windowsill coping concrete precast block comprises a windowsill coping concrete precast block body, is suitable for projects with a very tight construction period, and is characterized in that the thickness of the windowsill coping concrete precast block body is set to be larger than or equal to 100 mm, the width of the windowsill coping concrete precast block body is equal to the thickness of a wall, the length of the windowsill coping concrete precast block body is set to be larger than or equal to 250 mm, and an oblique slope angle is further arranged at one end in the length direction; two steel bars arranged in parallel left and right are arranged in the windowsill coping concrete precast block body in the thickness direction, one ends of the steel bars are located in the precast block, and the other ends of the steel bars are exposed out of the precast block. The windowsill coping concrete precast block has the advantages that the structure is simple, manufacturing is convenient, reinforcing steel bars are embedded in the concrete precast block in advance, the size is small, the weight is light, the concrete precast block can be conveniently transferred to a construction floor, the technical intermittent time generated by pouring a concrete coping is shortened, and the construction period and the labor cost are saved.

Description

technical field [0001] The present invention relates to a concrete prefabricated block, in particular, to a window sill-topped concrete prefabricated block. Background technique [0002] The window sill topping concrete is usually formed on the site of the construction floor window, and the cast-in-place concrete is topped, resulting in a long technical interval, complicated production process and high production cost. [0003] Therefore, the known window sill topping concrete construction methods have the above-mentioned inconveniences and problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a window sill topped concrete precast block with a shortened construction period. [0005] To achieve the above object, the technical solution of the present invention is: [0006] A window sill-topped concrete prefabricated block, comprising a window sill-topped concrete prefabricated block body, is suitable for projects with a particularly...
