Background
Generally, the outer wall and the column of a high-rise building are integrated into a vertical surface from one floor to the top floor, and horizontal construction joints are inevitably left at the floors of the concrete structure due to the construction of each floor in different times. The method for erecting the formwork of the outer vertical face comprises the following steps: and finishing the construction of the lower concrete structure, and then constructing the upper concrete structure. When the upper concrete structure template is erected, the outer wall and the column template are hung to the lower concrete structure and extend below the horizontal construction joint of the floor. And applying pressure outside the lower hanging template in a manner of reserving bolts and the like to ensure that the inner side of the template is tightly attached to the side surface of the construction joint of the lower concrete structure, and finally pouring the concrete of the upper structure. However, when the lower layer concrete structure is constructed, the upper opening of the structure is difficult to be free from the phenomenon of mold expansion, so that the side edge of the horizontal construction joint is not flat and straight, the lower hanging template of the upper layer concrete structure is difficult to be tightly attached to the concrete surface, and the slurry leakage phenomenon occurs. In addition, due to the fact that the surface of the horizontal construction joint between the lower layer concrete structure and the upper layer concrete structure is roughened, the construction joint is prone to being uneven, and therefore joints at the concrete joint of the horizontal construction joint are uneven, straight and attractive.
Disclosure of Invention
The technical task of the utility model is to solve prior art not enough, provide a horizontal construction joint formwork device of concrete structure, through this device, the horizontal construction joint of concrete structure is straight pleasing to the eye, leak-proof thick liquid.
The utility model discloses the technical scheme who adopts as follows:
the utility model provides a horizontal construction joint formwork device of concrete structure, including prop up locate concrete structure floor outer wall or the inboard template of wall post and prop up locate the outside template in concrete structure floor outer wall or the wall post outside, through split bolt connection, its characterized in that between the inside and outside template: a square strip-shaped template is fixed at the upper edge part of the inner side of the outer side template, and the top surface of the square strip-shaped template is flush with the top surface of the outer side template; the concrete floor outer wall or wall column filling cavity is defined by the inner side template, the outer side template and the square strip-shaped template, and the top surface of the square strip-shaped template is flush with the horizontal construction joint of the concrete floor outer wall or wall column.
The horizontal construction joint formwork device of the concrete structure is characterized in that: the square strip-shaped template is a square wood strip, and the square wood strip is fixed on the outer template through round nails or wood screws.
The concrete structure floor outer wall or the wall column is a lower layer concrete structure floor outer wall or a lower layer concrete structure floor wall or a lower layer concrete structure wall column. The inner and outer formworks are lower-layer concrete structure formwork systems designed through calculation, meet the size of the section of a concrete structure, and have the strength and rigidity for bearing all loads when concrete is poured. The cross-sectional dimension of the square wood strip is 20mm multiplied by 15 mm. The outer wall and the column template of the lower layer concrete structure are 15mm glued templates.
The horizontal construction joint used between the upper concrete structure and the outer wall and the column of the lower concrete structure is characterized in that the corresponding size of the template is adjusted if other horizontal construction joints of different concrete structures are constructed, but the template device is not changed.
The utility model discloses a theory of operation does:
the utility model discloses a along the fixed square strip type module in position on the inboard of outside template, like this, concrete structure floor outer wall or wall post pour the back of form removal, a recess then appears at the position that corresponds square strip type module in concrete structure floor outer wall or wall post, can avoid lower floor's concrete structure the form phenomenon that rises like this, also avoid causing the uneven straight phenomenon of horizontal construction joint side. Therefore, the lower hanging template of the upper concrete structure can be easily attached to the concrete surface, and the slurry leakage phenomenon is avoided.
The utility model has the advantages as follows:
the utility model discloses the preparation installation construction is simple, eliminates horizontal construction seam and leaks thick liquid for the seam is straight pleasing to the eye, and impression quality is good after the form removal. The utility model relates to a rationally, simple structure, convenient operation, safe and reliable have fine using value widely.
Detailed Description
In order to make the aforementioned objects, features and characteristics of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, which are shown in fig. 1 to 3.
A horizontal construction joint formwork device of a concrete structure comprises an inner side formwork 8 erected on the inner side of a concrete structure floor outer wall or wall column 3 and an outer side formwork 1 erected on the outer side of the concrete structure floor outer wall or wall column 3, wherein the inner side formwork 8 and the outer side formwork 1 are connected through a split bolt 4, a square strip formwork 2 is fixed on the upper edge of the inner side of the outer side formwork 1, and the top surface of the square strip formwork 2 is flush with the top surface of the outer side formwork 1; the inside formwork 8, the outside formwork 1 and the square strip formwork 2 enclose a filling cavity of the concrete floor outer wall or the wall column 3, and the top surface of the square strip formwork 4 is flush with the horizontal construction joint 5 of the concrete floor outer wall or the wall column.
The implementation method comprises the following steps: according to the section design size and load of the concrete structure floor outer wall or wall column, the inner and outer side formworks 8 and 1 are erected, and the inner and outer side formworks 8 and 1 are installed and reinforced. Preparing a square strip-shaped template 2, fixing the square strip-shaped template 2 at the upper edge part of the inner side of the outer template, and making the top surface of the square strip-shaped template 2 coincide with the height of the floor. And then, pouring an outer wall or a wall column 3 of the lower concrete structure floor. And after the concrete reaches the form removal strength, removing the form, and forming a groove on the horizontal construction joint of the lower-layer concrete structure corresponding to the square strip-shaped template 2. And then, erecting an upper concrete structure floor outer wall or wall column template 7, hanging the upper concrete structure outer wall or wall column template 7 downwards and covering a groove at the horizontal construction joint 5, and straightening the upper concrete structure floor outer wall or wall column template 7 at the groove. Next, the upper concrete structure 6 is concreted and the grooves are filled with mortar in the concrete. Finally, the form is removed, and after the form is removed, the concrete horizontal construction joint 5 is flat and beautiful and does not leak slurry.
The above, only be the preferred example of the utility model discloses, not be used for the restriction the utility model discloses, all basis the utility model discloses a technical entity is any slight modification, equivalent replacement and improvement to do the above embodiment, all should be contained within the technical scheme's of the utility model protection within range.
