Description

Windowsill coping structure

Technical Field

The utility model relates to a construction technical field specifically is a windowsill bears down on one structure.

Background

With the standardization and standardization of building structures, the requirements for building construction are also higher and higher. In recent years, the overall construction quality of the construction industry is generally improved, the engineering quality becomes the focus of social attention, the quality consciousness of the whole people is continuously improved, and the engineering quality is the sample of the survival of construction enterprises.

At present, in the building engineering, if the outer wall is masonry structure, the brick pillar length of window opening both sides is general less, presses the minimum length of top anchor into both sides brick pillar for guaranteeing the windowsill, and the windowsill is pressed the top and is generally adopted cast-in-place construction: when the brickwork is built by laying bricks or stones to windowsill coping elevation height, formwork, reinforcement, concreting are carried out earlier, and the brickwork on upper portion is built by laying bricks or stones again after the form removal, need guarantee that the windowsill coping imbeds the inside 120mm of brickwork simultaneously. The method has the advantages that the windowsill coping is poured firstly and then bricked, the forming quality is good, the bricks are tightly combined with the embedded part of the coping, and the phenomenon of water seepage channels caused by untight pouring of concrete at the corners is avoided; the method has the defects that the masonry work can not be completed at one time, and the masonry at the upper part can be built only after the windowsill coping concrete pouring is completed and the final setting formwork removal is carried out. Because windowsill bears down the top and pours the process and masonry process and build by laying bricks or stones the process and can't stagger, consequently increased the time limit for a project of brickwork, the construction progress is slower.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve lies in: the utility model provides an improve windowsill coping structure that brickwork construction progress can also prevent the brickwork infiltration to solve current windowsill coping and pour process and brickwork and build the process and stagger, the slower problem of construction progress.

In order to solve the technical problem, the utility model provides a following technical scheme:

a windowsill coping structure comprises two precast concrete blocks, a reinforcing steel bar and coping concrete; precast concrete piece one side pre-buried connecting reinforcement and stretch out the precast concrete piece, still be equipped with vertical stagnant water recess in precast concrete piece side of pre-buried connecting reinforcement, the precast concrete piece imbeds windowsill both sides brickwork respectively to guarantee that the precast concrete piece flushes with windowsill both sides brickwork in the side of pre-buried connecting reinforcement, the connecting reinforcement of two precast concrete pieces passes through reinforced connection, still press a concrete connection through the pouring between the precast concrete piece.

Preferably, before the top-pressing concrete is poured, the side surface of the precast concrete block in which the connecting steel bars are embedded is roughened.

Preferably, the height and the width of the precast concrete block are correspondingly the same as those of the capping concrete, and the length of the precast concrete block is not less than 120 mm.

Preferably, the precast concrete block has the same strength grade as that of the capping concrete.

Preferably, the connecting steel bars and the reinforcing steel bars have the diameter of 8 mm.

Preferably, the length of the connecting steel bar extending out of the precast concrete block is not less than 250 mm.

Preferably, the depth and the width of the water stopping groove are both 20 mm.

Preferably, the connecting steel bar and the steel bar are fixed by binding or welding.

Compared with the prior art, the beneficial effects of the utility model are that:

this windowsill bears structure on one under the prerequisite that does not influence the quality of building by laying bricks or stones, has guaranteed the continuity of brickwork process of building by laying bricks or stones, has improved the construction progress of building by laying bricks or stones to through the setting of stagnant water recess, not only can prevent the infiltration, can also strengthen precast concrete piece and the interlock of bearing concrete and form a whole, improve windowsill bears intensity.
