Description

Technical part

The utility model belongs to the technical area of the assembled building and relates in particular to an adjustable shaped plate for prefabricated panels on columns with variable cross-sections.

Background technology

Currently, in assembled buildings, especially in assembled plant projects, the node design of the columns with variable cross-section is widespread. It can meet the space utilization requirements of the facility while fulfilling the structural forces. But for the production line of prefabricated components, the node design of the columns with variable cross-section places relatively high demands on the design of prefabricated components. If the shape design is not good, it results in poor production efficiency, so that the cost of the shape increases and the economy of the knot design is lost.

In assembled plant projects, the nodal design of the variable cross section columns is commonly used to reduce the cross section of the column by floor in the ascending floors and to reduce the amount of reinforcing steel by floor while fulfilling the force to achieve the purpose of cost reduction. In the manufacture of prefabricated components, however, the cross-section of the column changes floor by floor, and thus the recess sizes of the prefabricated panels corresponding to the column are different on each floor. The template for the recess, called the "tool", should also be of changing size. If the "tools" are made of the appropriate sizes, the number of tools will be large. As in 6th As shown, the "tool" in the prior art mold plate cannot be adjusted so that the mold plate can only be used to make prefabricated panels with a single recess size. In the manufacture of prefabricated panels on columns of variable cross-section, different molded panels are required for prefabricated panels with different types of recess sizes, which not only causes waste but also makes workers inconvenient and reduces production efficiency.

Contents of the invention

In order to solve the above-mentioned problems of the prior art, the object of the utility model is to provide an adjustable shaped plate for prefabricated panels on columns with variable cross-section, which can adapt its structure according to the shape of the prefabricated panel.

• Eine einstellbare Formplatte für vorgefertigte Platten an Säulen mit variablem Querschnitt, die eine Hauptschablone umfasst, wobei die Hauptschablone ringsum mit Anschlagkanten versehen ist und die Hauptschablone mit einem Zwischenwerkzeug versehen ist, wobei das Zwischenwerkzeug zwei einteilig gebildete Abzweigwerkzeuge umfasst, wobei die anderen Enden der Abzweigwerkzeuge jeweils mit einem Endwerkzeug überlappt sind, wobei die anderen Enden der beiden Endwerkzeuge jeweils mit einer von zwei benachbarten Anschlagkanten auf der Hauptschablone überlappt sind. Die beiden Abzweigwerkzeuge des Zwischenwerkzeugs bilden einen bestimmten Winkel und die Abzweigwerkzeuge sind mit den Endwerkzeuge überlappt, und dann das Zwischenwerkzeug, die beiden Endwerkzeuge sowie die zwei benachbarten Anschlagkanten bilden ein Viereck. Nachdem die Hauptschablone mit Beton gefüllt wurde, wird der Beton durch die Endwerkzeuge und das Zwischenwerkzeug blockiert, und die gegossene vorgefertigte Platte, die eine rechteckige Platte mit einer vierseitigen Aussparung darstellt, wird gebildet.
• Diese viereckige Aussparung passt zur Säule. Wenn das Abzweigwerkzeug relativ zur Endwerkzeuge bewegt wird, ändert sich die Größe der viereckigen Aussparung und damit kann das Gebrauchsmuster verwendet werden, um vorgefertigte Platten mit unterschiedlichen Aussparungsgrößen zu gießen, was die Anpassung an jedem Abschnitt der Säule mit variablem Querschnitt erleichtert, ohne die Formplatte und das Werkzeug an der Aussparung ersetzen zu müssen.

If the portion of the branch tool that is not provided with an elongated hole is flush with the end tool, the area of the uneven surface of the supported prefabricated panel is reduced. When the end face of the end tool is in contact with the portion of the branching tool that is not provided with an elongated hole, the surface of the recess of the prefabricated plate is in fact completely flush. If there is a gap between the end face of the end tool and the section of the branching tool that is not provided with an elongated hole, the concrete enters the gap and a protrusion about 1 cm thick is formed on the side surface of the recess of the prefabricated slab . For this protrusion, if the variable cross-section column is an in-situ concrete structure, the protrusion will precisely overlap the column, increasing the integrity. If the variable section column is an assembled structure, the protrusion can be released by inserting several rectangular rubber pads 0.5 cm wide. According to the changing size, the appropriate number of rubber pads can be used. The manufacturer can also make some adjustment blocks with a width of 0.2 cm to realize the size adjustment.

In the preferred embodiment of the present utility model, the angle of the two branch tools is 90 °. In general, the cross-section of the variable cross-section column is square or rectangular, then the angle between the two branching tools is set to 90 °.

• Das Zwischenwerkzeug des Gebrauchsmusters kann relativ zur Endwerkzeug eingestellt werden, und nach der Einstellung ändert sich die Größe des Vierecks, das von dem Zwischenwerkzeug, der Endwerkzeuge und zwei benachbarten Anschlagkanten umgeben ist, dann wird die Größe an der Aussparung der hergestellten vorgefertigten Platte verändert. Entsprechend der Größe der Säule mit variablem Querschnitt wird die Position des Zwischenwerkzeugs und der Endwerkzeuge so eingestellt, dass sich die hergestellte vorgefertigte Platte an unterschiedlichen Abschnitten mit unterschiedlicher Größen der Säule mit variablem Querschnitt anpassen kann. Das Gebrauchsmuster kann verwendet werden, um vorgefertigte Platten mit unterschiedlichen Aussparungsgrößen herzustellen, ohne die Formplatte auszutauschen, was die Handhabung erleichtert und die Herstellung der vorgefertigten Platten mittels des Gebrauchsmusters effizienter macht.
