Description
Technical Field
The utility model relates to a precast concrete component production technical field, concretely relates to device of prefabricated coincide floor truss muscle height of regulation and control.
Background
With the gradual popularization of the assembly type technology, the prefabricated truss rib laminated slab becomes an assembly type concrete product with mature technology, wide application, convenient construction and environmental protection.
The prefabricated truss rib composite slab is an assembled integral floor slab formed by overlapping a prefabricated bottom plate and a cast-in-place reinforced concrete layer. The truss reinforcing steel bars pre-embedded in the composite slab consist of upper chord reinforcing steel bars, web member reinforcing steel bars and lower chord reinforcing steel bars. The prefabricated slab and the laminated layer have certain functions in the aspects of increasing the rigidity of the floor under the action of short working conditions (production, transportation and hoisting), increasing the shearing resistance of the prefabricated slab and the laminated layer and serving as a split heads bar. Meanwhile, during the electrical professional construction, a high enough clearance area needs to be reserved between the truss rib upper chord steel bar and the prefabricated bottom plate to serve as a channel for pipeline installation.
At present, a production enterprise usually fixes a truss rib by arranging a cushion block at the lower part of the truss rib or firmly binding a lower chord rib and a plate bottom reinforcing steel bar, and the height of the truss is not effectively and reasonably controlled. In the process of pouring concrete, the truss ribs are easy to float upwards or sink under pressure, so that the ultrahigh truss ribs influence the thickness of a plate gluten protection layer, or the insufficient clearance between the upper chord ribs and the bottom plate surface influences the installation and construction of pipelines.
Disclosure of Invention
An object of the utility model is to provide a device of prefabricated coincide floor truss muscle height of regulation and control.
The utility model has the technical scheme that: the utility model provides a device of prefabricated coincide floor truss muscle height of regulation control, includes prefabricated truss muscle superimposed sheet, prefabricated truss muscle superimposed sheet includes base, vertical pole setting, goes up adjusting nut, adjusting screw, fixed bolster, vertical pole setting down, its characterized in that, base, vertical pole setting and fixed bolster are a holistic gate-type support, and the gate-type support is fixed by two square steels, and the middle full length space of reserving makes adjusting screw can pass and slide at the horizontal direction. According to the further technical scheme, the adjusting screw rod sealing cover is in threaded connection with the screw rod, so that the adjusting screw rod sealing cover is convenient to disassemble and replace.
The utility model has the advantages that:
1. the device has simple structure, and is easy for mass production and processing; the quality is light, and the workman can dismouting at will move.
The utility model realizes the adjustable and controllable height of the truss rib of the superimposed sheet, and ensures the accuracy of member processing and the convenience of site construction; the movable and adjustable screw rods enable the device to be suitable for laminated plates of all specifications in universality by one set of device.

Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1, the utility model relates to a device of prefabricated coincide floor truss muscle height of regulation and control, including prefabricated truss muscle superimposed sheet, prefabricated truss muscle superimposed sheet includes base 1, vertical pole setting 2, goes up adjusting nut 5, adjusting nut 6, adjusting screw 4, fixed bolster 3 down, its characterized in that, base 1, vertical pole setting 2 and fixed bolster 3 are a holistic portal frame.
The portal frame is fixed by two square steels, the fixed bolster is equipped with the through-hole that distributes along the horizontal direction, go up adjusting nut 5, adjusting nut 6 sets up respectively in the top and the below of fixed bolster down, adjusting screw runs through the horizontal through-hole and through last adjusting nut 5, adjusting nut 6 is connected with the fixed bolster down, adjusting screw can remove along the horizontal through-hole direction, adjusting screw 4's lower extreme is equipped with the spacing crotch 7 and the separation blade 8 that are used for with prefabricated truss muscle fixed connection, adjusting screw's upper end is equipped with threaded connection's closing cap 9.
The adjusting process of the prefabricated truss rib laminated slab comprises the following steps:
after prefabricated superimposed sheet reinforcement accomplishes, fix base 1 on the mould mesa of component processing (can use high-strength magnet) before concrete placement, there is vertical pole setting 2 on the base 1, adjusting nut 5, adjusting nut 6 make adjusting screw 4 can carry out horizontal slip on fixed bolster 3 down in the adjustment, then remove adjusting screw 4 to the position at truss muscle place, dial separation blade 8 of spacing crotch 7 up, catch the back with the last chord reinforcing bar of truss muscle with spacing crotch 7, dial separation blade 8 down, make truss muscle and adjusting screw 4 fixed. The truss ribs are lifted to the height required by the design, the upper adjusting nut 5 and the lower adjusting nut 6 are locked, the height of the screw rod is guaranteed to be unchanged, and the verticality of the screw rod is guaranteed. The two ends of each truss rib are all controlled by the device, a plurality of adjusting screw rods can be placed on the same fixing support, and the heights of the truss ribs in the same laminated slab can be conveniently adjusted.
And after the concrete pouring of the laminated plate is finished, the lower adjusting nuts 6 can be loosened before the laminated plate is maintained in a kiln, the separation blades 8 are pulled open, the screw rods are separated from the truss ribs, and the fixing support is disassembled.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
