The device provided by the utility model has the benefits as follows: 1, the structure is simple and practical; 2, the BDF thin-walled cement hollow pipes can be fixed in a line very easily, and the pipe spaces between the BDF thin-walled cement hollow pipes are kept uniform; during concrete casting, the BDF thin-walled cement hollow pipes are prevented from floating, so as to guarantee the casting quality; and 4, the positioning mechanisms are made of engineering excessive materials, so as to reduce cost to the maximum extent and achieve the effects of energy conservation and environmental friendliness.
Description
Technical field
The utility model relates to technical field of building construction, relates in particular to a kind of cast-in-place concrete floor BDF thin wall cement hollow section location and anti-floating system.
Background technology
Cast-in-place concrete hollow building roof is after common beam-and-slab floor, close rib building roof etc., a kind of novel floor structural form that success is developed.It is in superstructure, to place the circular or cement thin-walled hollow section of square BDF of flush type as internal mold by certain rule, forms the superstructure of cavity through poured in place concrete.In the cast-in-place concrete hollow building roof construction, fixedly BDF thin wall cement hollow section is the emphasis and the difficult point of total engineering.Because BDF thin wall cement hollow section is difficult to be fixed into line, pipe is apart from being difficult to keep even; Cause hollow section come-up during concreting easily, cause under the displacement of plate muscle, the plate concrete cover to reinforcement thickness bigger than normal, influence concrete pouring quality.Therefore, we press for a kind of positioner, to make things convenient for the installation of BDF thin wall cement hollow section, make BDF thin wall cement hollow section be easy to be fixed into line, guarantee construction quality.
Summary of the invention
The utility model technical problem to be solved provides a kind of BDF thin wall cement hollow section simple in structure location and anti-floating system; This device is fixed into line with BDF thin wall cement hollow section easily; And BDF thin wall cement hollow section is non-rising when concreting, has guaranteed pouring quality.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: a kind of BDF thin wall cement hollow section location and anti-floating system; Include a plurality of location units; Each positioning unit comprises fixed block, detent mechanism and steel mesh reinforcement; Detent mechanism is positioned on the fixed block, and steel mesh reinforcement is between detent mechanism and fixed block; Described detent mechanism includes locator card and is positioned at the column under the locator card, and column inserts in the hole of fixed block; BDF thin wall cement hollow section places on the locator card, and BDF thin wall cement hollow section is connected with reinforcing bar on the steel mesh reinforcement through iron wire.
Press such scheme, the adjacent positioned unit of horizontally set is connected by cross bar.
Press such scheme, the positioning unit spaced set of described horizontally set.
Press such scheme, described cross bar is that Ф 8 reinforcing bar clout spot welding are processed.
Press such scheme, described locator card is a circular arc, and the diameter of locator card is than the big 1-3mm of diameter of BDF thin wall cement hollow section.
Press such scheme, described fixed block is the cement mortar cushion block.
Press such scheme, described detent mechanism is that Ф 8 reinforcing bar clout spot welding are processed.
The beneficial effect of the utility model is: 1, simple in structure, and practicality.2, can easily BDF thin wall cement hollow section be fixed into line, the pipe that makes BDF thin wall cement hollow section is apart from keeping evenly.3, BDF thin wall cement hollow section is non-rising when concreting, has guaranteed pouring quality.4, utilize the engineering clout to make detent mechanism, reduce cost energy-conserving and environment-protective to the utmost.
Description of drawings
Fig. 1 is the structural representation of the utility model cross tube direction.
Fig. 2 be the utility model along tube side to structural representation.
The specific embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, a kind of BDF thin wall cement hollow section location and anti-floating system include a plurality of location units, the positioning unit spaced set of horizontally set, and the adjacent positioned unit of horizontally set is connected by cross bar 7, and the positioning unit that vertically is provided with has two; Each positioning unit comprises cement mortar cushion block 5, detent mechanism and steel mesh reinforcement 2, and steel mesh reinforcement 2 is between detent mechanism and cement mortar cushion block 5; Described detent mechanism includes the locator card 4 that is circular arc and is positioned at the column 6 under the locator card 4, and column 6 inserts in the hole of cement mortar cushion blocks 5; BDF thin wall cement hollow section 1 places on the locator card 4, and BDF thin wall cement hollow section 1 is connected with reinforcing bar on the steel mesh reinforcement 2 through 14# iron wire 3.The diameter of described locator card 4 is than the big 2mm of diameter of BDF thin wall cement hollow section 1.Said cross bar, locator card 4 and column 6 are processed for Ф 8 reinforcing bar clout spot welding.Described steel mesh reinforcement is layered on above the soffit template.
Work progress is:
1) utilizes Ф 8 reinforcing bar clout spot welding to connect before BDF thin wall cement hollow section 1 is installed and make BDF thin wall cement hollow section locator card 4, column 6 and cross bar 7, column 6 is welded on the lower end of locator card 4; Locator card 4 and cement mortar cushion block 5 sizes are confirmed according to design;
2) mounting reinforcing steel bars net 2 on the soffit template;
3) lay detent mechanism by design BDF thin wall cement hollow section 1 comb detail drawing, the column 6 of detent mechanism is inserted in the hole of cement mortar cushion blocks 5, with the level and the upright position of accurate location BDF thin wall cement hollow section 1; The detent mechanism that cross bar 7 is connected horizontally set;
4) BDF thin wall cement hollow section 1 is put into the locator card of putting 4;
