Abstract
The utility model discloses a revolvable ground anchor device for a single-side support form, comprising a part which is fixed with a supporting frame. The revolvable ground anchor device is characterized in that the ground anchor device comprises a pre-embedded part and a connecting part; and the pre-embedded part is connected with the connecting part through a connecting sleeve. The revolvable ground anchor device is divided into two parts instead of adopting the conventional integrated machining, i.e. the pre-embedded part and the connecting part which are connected through the connecting sleeve, therefore, only the pre-embedded part is required to be pre-embedded during construction and the connecting part is used as a revolution part, thereby improving the use frequency and the efficiency of a ground anchor and lowering cost.
Description
Technical field
The utility model relates to a kind of single side formwork with having enough to meet the need ground anchorage.
Background technology
Along with developing rapidly of city size, the city middle-high building is increasing, the nucleus in city especially, an inch of land is an inch of gold.The construction plant is narrow day by day, outer wall of basement usually can't not adopt traditional bilateral formwork support process to construct because construction does not have the operating space problem, single side formwork technology thereby obtain broad development obtains more and more application more in the outer wall of basement construction.In the single side formwork work progress, need earth anchor is carried out pre-buried, after wall construction is finished, earth anchor because of imbed in the body of wall or floor in, and can't realize turnover utilization, cause the waste of material.
The utility model content
Technical problem to be solved in the utility model provides a kind of single side formwork with having enough to meet the need ground anchorage, has overcome above-mentioned defective.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of single side formwork is with having enough to meet the need ground anchorage, comprise with the fixedly connected double flute steel of formwork-support and be connected back cord, pad and nut, it is characterized in that: described ground anchorage also comprises built-in fitting and connector, is connected by branch sleeve between described built-in fitting and the connector.
Built-in fitting links to each other with connector to hold and is processed into screw thread silk head.
Built-in fitting is held with burying and is adopted 135 ° of crotches, installs with angle at 45, ground.
Formwork-support is linked to be integral body by the double flute steel backing is stupefied with ground anchorage.
Described nut is positioned at the stupefied top of double flute steel backing with pad ground anchorage is fixedlyed connected with formwork-support.
The utlity model has following advantage:
The utility model is not adopting integral body traditionally to process, but is divided into two parts, and promptly built-in fitting and connector connect by branch sleeve; Thereby only needing carry out pre-buried in the construction to built-in fitting, connector uses as the turnover part, thereby improves earth anchor frequency of utilization and efficient, reduces cost.

The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1,1-built-in fitting, 2-connector, 3-sleeve
As shown in Figure 2,4-template, 5-ground anchorage, 6-formwork-support
As shown in Figure 3,7-double flute steel connects back cord, 8-pad, 9-nut
Outer wall of basement carries out the single side formwork construction process and is divided into 8 procedures: 1. exterior wall outside brick fetal membrane is built by laying bricks or stones and is plastered; 2. waterproof roll and fish tail and waterproof layer construction; 3. brick fetal membrane outside backfilling of earthwork; 4. buried built-in fitting and lead wall construction; 5. colligation exterior wall wall column reinforcing bar and the topping cushion block is set; 6. install side template within the walls; 7. exterior wall concreting; 8. remove side template within the walls.
After preceding three process construction is finished, the earth anchor built-in fitting is constructed, pre-buried spacing gets through the earth anchor Force Calculation.Built-in fitting becomes miter angle with ground; require during site operation to draw logical line, guarantee that embedded part is on the same horizon, earth anchor build lead wall before double thread take safeguard measure; with materials such as Polypropylence Sheet parcel nipple; and tighten, concrete sticks on the screw thread when avoiding constructing, and influences the quality of connection between sleeve and the embedded part; when guaranteeing concreting; not positioning of built-in fitting or deflection are welded in the embedded part point on the horizontal additional bar, note during spot welding cutting the diameter that decreases embedded part.After built-in fitting construction is finished, build and lead wall, the skew force that when leading wall intensity and should guarantee built-in fitting not because of concreting earth anchor is produced destroys.
In advance steel form and support are connected firmly with HOOK BOLTS during mounting template, at the template end position wooden a tree, used in making timber for boats are set, adopt steel pipe and U holder fixing, wooden a tree, used in making timber for boats and lower margin screw mandrel are born the pressure of template and support jointly.The lifting single form guarantees that the template end opening aligns with the wall sideline, and fixes with steel pipe that the template side need be pasted sponge strip and guarantee not spillage earlier, after template is fixing, with sleeve built-in fitting and connector is fused, and guarantees to connect closely.Built-in fitting leaves the space with after connector is connected with sleeve in the middle of the sleeve, guarantees to connect when fastening, and internal thread of sleeve should not pushed and damage, so that improve frequency of utilization and efficient.After the lifting 5-6 piece template, the interspersed channel-section steel that the embedded part system is installed is fixed as one earth anchor and support.Adjust the template verticality by stone bolt, after the adjustment deviation reaches requirement, support is fused with the horizontal steel pipe of twice, make the single side formwork system have good whole stability.Completely spread scaffold floor on the single side formwork operating platform, the outside adopts the horizontal steel pipe of twice to protect, and guarantees when concreting, guarantees operating personnel's safety.
Check the embedded part system before the concreting, and fastening once more, and when guaranteeing concreting, the template end opening can spillage.During concreting, speed of perfusion can not be avoided template is produced excessive lateral pressure greater than designing requirement, needs layering to carry out when building body of wall, needs during the concreting of upper strata to carry out before lower floor's initial set.Build the on-the-spot special messenger's nurse of sending, observe the falsework situation, in time adjust concreting height and speed of perfusion, the mode ship slurry situation that prevents to rise occurs.
When concrete strength can guarantee that its surface and corner angle are injury-free, can remove side form.During stripping, remove the scaffold bearing diagonal earlier, runing rest is regulated screw mandrel, utilize falsework gravity, make template break away from concrete wall, unclamp the channel-section steel that connects earth anchor and support, remove the connector and the branch sleeve of earth anchor then, and, be used for construction next time with special-purpose collecting box categorised collection.
