The method comprises the following steps:
the invention also provides an installation method of the embedded installation structure, which comprises the following steps:
step S1, determining the position of each embedded sleeve component for the component to be installed, setting out lines on a template on the bottom surface of the concrete construction layer according to the position of each embedded sleeve component, positioning the embedded sleeve components, forming a plurality of through holes in corresponding positions on the template, and simultaneously ensuring that each through hole is matched with the diameter of a fastening screw in each fastening mechanism.
Specifically, the to-be-installed member in the embodiment may be a support and hanger, or may be another building element that needs to be installed on a concrete structure layer.
In this embodiment, before the construction, the operating personnel need carry out the secondary deepening design to the installation pipeline according to the pipeline construction drawing, confirm the mounted position of treating the installed part to further confirm the position of installing each pre-buried sleeve subassembly that treats the installed part and use. After the position of the embedded sleeve assembly for installing the to-be-installed part is determined, the position of each embedded sleeve assembly is determined on a floor cast-in-place concrete construction bottom template, and a through hole matched with the diameter of the fastening screw is formed in the corresponding position on the template. That is to say, actually when the installed part is treated in the installation, need the pre-buried mounting structure of multiunit, it is corresponding, pre-buried sleeve subassembly in the pre-buried mounting structure of every group and the used fastener of installed part is treated in the installation and uses in the cooperation one by one.
In this step, fix a position in advance according to waiting the embedded sleeve subassembly of installed part concrete position, for the welding embedded part with beat the fixed mode of expansion bolts, great improvement installation effectiveness and installation accuracy.
And step S2, screwing each fastening screw with the lower end of the corresponding embedded sleeve component, and penetrating each fastening screw through the template.
Specifically, before this step, it is necessary to assemble each embedded sleeve assembly 1, and the specific method of assembly is as follows: and (3) fastening the anchoring plate 12 at the upper end of the embedded sleeve 11 by using a first bolt 13, and installing a first elastic gasket 9 between the anchoring plate and the embedded sleeve 11 to form an embedded sleeve assembly to be installed.
In step 2, preferably, after the fastening screw 21 is inserted into the lower end of the embedded sleeve assembly 1, a second elastic gasket 10 is inserted into the fastening screw at a position close to the upper end, and a guide 22 is hung on the lower end of the fastening screw 21, so that the guide guides the fastening screw to pass through the formwork. Namely: and arranging a second elastic gasket at the joint of the fastening screw and the lower end of the embedded sleeve, and then hanging a guide piece at the slotted end of the fastening screw and taking the fastening screw and the guide piece as a whole to penetrate through the through hole in the template.
More preferably, the guide is pulled by pulling the fastening screw through the formwork to expose the fastening screw by applying a pulling force to the back surface of the formwork 4, and then the tie plate is attached to the back surface of the formwork.
And step S3, penetrating each pressing piece into the corresponding fastening screw, and applying acting force to the pressing pieces to enable the corresponding embedded sleeve component to be tightly pressed on the template.
Particularly, will compress tightly the piece and pass fastening bolt through the perforation on the fastening bolt, later can strike and compress tightly the piece and make it and template looks chucking to the realization is compressed tightly on the template with pre-buried sleeve subassembly.
In the case where the guide 22 is used in step S2, the guide 22 may be removed after the fastener sleeve assembly is pressed against the pattern plate 4 in step S3.
And step S4, binding floor slab steel bars on the template, pouring concrete and maintaining, so as to realize the pre-embedding of the pre-embedded sleeve component.
Specifically, concrete is cast in place between the front surface of the formwork 4 and the upper end of the embedment sleeve 11 to anchor the embedment sleeve 11 in the concrete structure.
And step S5, applying reverse acting force to each pressing piece after the cast-in-place concrete reaches the curing age and before the template is dismantled, loosening and taking off the pressing pieces, dismantling each fastening screw from each corresponding embedded sleeve component, and recycling the fastening screws for reuse.
Specifically, the backing plate can be removed while the pressing member 3 is removed, and then the backing plate 6, the pressing member 3, and the fastening screw 21 can be recovered for subsequent reuse. Wherein, when dismantling fastening screw, can utilize and dismantle sleeve 7 and demolish to improve the efficiency of construction.
