Abstract
The utility model discloses a bracket concrete construction moulding plate which is formed by connecting panels and brackets, wherein the panels adopt large steel moulding plates, the brackets are in trapezoidal frame structure, the panels and the trapezoidal brackets on an upper layer are respectively fixed on the panels and the trapezoidal brackets on a lower layer by bolts, a supporting post is embedded in a casting bin on each layer, one end of a pull strip is fixed on the panels, and the other end of the pull strip is fixed on an embedded piece in each casting bin by the supporting post. The utility model has the advantages of simple and practical structure, low cost, convenient operation and perfect control.
Description
[technical field]
The utility model relates to a kind of concrete construction template, particularly a kind of bracket concrete construction formwork that is applicable to the water power construction field.
[background technology]
The construction work especially concrete bracket in the hydroelectric project is the construction part of more complicated always, and these big brackets that cantilever out often are arranged in the riverbed, and the unsettled discrepancy in elevation in bottom is big, and the job practices difficulty of setting up support as employing is very big.Introduce according to " water conservancy and hydropower construction organization design manual (three) " and other interrelated data, the following form of the many employings of bracket concrete template in China's water power construction: interior pull-type, draw lift-type in once used peripheral hardware counterweight of tripod brace type and Three Gorges Projects and the platform.Above template scheme all has its shortcoming that is difficult to overcome, and is big as difficulty of construction, poor stability, and what take is long in time limit, the cost height, its safety and economy, speed of application, construction quality all are difficult to satisfy the requirement of modern project.
[summary of the invention]
The purpose of this utility model is: a kind of bracket concrete construction formwork that can rapid construction is provided, solve traditional bracket template scheme speed of application slow (must treat that concrete reaches 70% above intensity ability form removal construction), consume material many (single outer support or the interior pull-type lot of materials that need to consume), tie rod and screw rod are loosening easily in the process of building, thereby make concrete quality can not get guaranteeing, operating personnel's safety also can not get the shortcoming that guarantees, reach the quickening speed of application, improve the safety of construction quality and operation, comfortableness reduces the purpose of construction cost simultaneously.
The purpose of this utility model is achieved in that a kind of bracket concrete construction formwork, be formed by connecting by panel and support, panel adopts large-scale steel form, support is the ladder-shaped frame structure, last layer panel and trapezoid support are separately fixed on next deck panels and the trapezoid support by bolt, each layer is built the pre-buried support column of position in storehouse, and tie rod one end is fixed on the panel, and the other end is fixed on the built-in fitting of building in the position in storehouse by support column.
The utility model on the structure design of template and reinforcement measure, adopted a kind of innovation half in draw the construction technology of semi-cantilever, above each layer template of bracket adopts lower floor to water the template outer platform of position in storehouse anchoring as supporting and operating platform, draw force structure in being aided with simultaneously as template, newly placed concrete can innerly draw stressed, just can carry out the dismounting of lower template so two-layer concreting is intact after 2～3 days, so of the present utility model simple and practical, have the advantage that cost is low, easy to operate, control is perfect.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of bracket first floor construction.
Wherein, Fig. 1 double as Figure of abstract.
[specific embodiment]
As shown in the figure, a kind of bracket concrete construction formwork, be formed by connecting by panel 1 and support 2, panel adopts large-scale steel form, support is the ladder-shaped frame structure, and the last layer trapezoid support is by being bolted to down on one deck trapezoid support, and each layer is built the pre-buried support column 3 of position in storehouse, tie rod 4 one ends are fixed on the panel, and the other end is fixed on the built-in fitting of building in the position in storehouse by support column.
As shown in Figure 2, bracket bottom dam body is built and is preferably adopted DK type dam cantilever form, after dam body is poured into bracket and plays slope point like this, directly utilize the A-frame of its template to make support platform the dismounting of dam cantilever form, otherwise play about 1 meter ironware of wanting pre-buried installation gusseted under the point of slope at bracket.Must be before the bracket construction by pre-buried good steel pipe of design and tie rod reinforcing bar in the storehouse.During the construction of bracket first floor, it is built the position in storehouse height and decides according to the dam body template configuration.General consistent with other template of dam body.
Bracket second layer when construction, treat that first floor concreting carried out later in intact 48 hours.Second layer template is directly installed on the first floor template, adopts bolt to connect between the template.More than each layer template by being bolted to down on one deck template.Its technological process is as follows:
Draw the column steel pipe in the welding template
Formwork hoisting
Formwork reinforcement
Assembling reinforcement reaches and is equipped with the storehouse
Concreting
Pre-buried next storehouse Steel-bar Pile
The position in storehouse maintenance.
Lower template and tripod are removed: since this process using be outer support and in draw the force mode that is subjected to that combines, newly placed concrete can innerly draw stressed, so two-layer concreting intact after 2～3 days (but lower-layer concrete built preferably completely more than seven days, also can build after 3～4 layers and tear open) just can be carried out the dismounting of lower template.
The utility model is at xuan-en, hubei Dong Ping power station upstream and downstream, flood discharge hole gate pier bracket and Ethiopia TEKEZE Be able to successful Application in the construction of power plant dam bracket, facts have proved, the utlity model has quick, use peace easy and simple to handle Complete comfortable, construction quality good, cost is low advantage.
