Description

A kind of precast prestressed T plate with skylight

Technical field

The utility model relates to technical field of building construction more particularly to a kind of precast prestressed T plates with skylight.

Background technique

In the prior art, reserving hole forms skylight before cast-in-site roof, it is common practice to before cast-in-place concrete, pre- It stays the position of skylight to prop up template, then cast-in-place concrete, forms skylight.

Reserving hole formation skylight there is a problem of following before cast-in-site roof: continuously putting in a skylight in large-sized workshop roof has Certain difficulty, and hole size is restricted.

Utility model content

In order to solve the problems in the prior art, the utility model provides a kind of precast prestressed T plate with skylight, The T plates advantage such as not only there are plate-girder combination, the load-bearing that can be pressurized, large span can be made, also having both with skylight, meet lighting and ventilation It is required that.The utility model is realized especially by following technical solution:

A kind of precast prestressed T plate with skylight, including panel, left flank, right flank, steel strand wires and mesh sheet；Wherein, It is placed with parallel the first distributing reinforcement and the second distributing reinforcement in the panel, skylight, two days are opened up between the distributing reinforcement Window bilateral symmetry is distributed；It pours to form skylight beam around the skylight；The left flank and right flank are symmetrically disposed on face Below plate, double-T shaped structure is formed；The mesh sheet is centrally disposed in flank, is distributed a plurality of steel strand wires in mesh sheet two sides；It is described Steel strand wires are fixed using strand tapered anchorage and anchor plate；Left and right both sides of the chest steel strand wires press left and right, direction tensioning symmetrical above and below respectively.

The T plate further includes built-in fitting and bottom built-in fitting as a further improvement of the utility model, in skylight beam On quadrangle arrange bottom built-in fitting, the distributing reinforcement outside arrange built-in fitting.

Suspension hook is fixed on panel as a further improvement of the utility model, shown suspension hook is symmetrical set.

Skylight beam further includes skylight beam arrangement of reinforcement as a further improvement of the utility model,；In the beam of skylight short side direction Add concealed beam.

The mesh sheet is reinforced mesh as a further improvement of the utility model,.

As a further improvement of the utility model, use YJM15-1 strand tapered anchorage, end using 1050mm high, 380mm wide, 100mm thick anchor plate.

Every steel twisted-line tension-force is 193KN as a further improvement of the utility model,.

The beneficial effects of the utility model are: the precast prestressed T plate with skylight of the utility model, has following excellent Point: 1, bearing capacity is big, and every square can at least bear 5.4kN；2, long line platform, arrangement property are good.The every section of mold is 10 meters long, totally 14 section, Composition is no more than 140 meters of arbitrarily long long line die station；3, self-supplying capacity, mold are different from tradition from prestressed stretch-draw power is born Double T molds；4, it can combine, using same set of pedestal and template, the rib of T plate is high, wide adjusted by mold of plate is changed；It can produce Different spans, various sizes of T plate product.

Specific embodiment

The present invention will be further described for explanation and specific embodiment with reference to the accompanying drawing.

As large scale prefabricated concrete component, the prestressing force T plate intention with skylight is dexterous, by skylight and T plate roofing Combine, suitable for the more demanding industrial premises of daylighting and coliseum etc..

As shown in Figs 1-4, the precast prestressed T plate with skylight of the utility model, including panel (1), left flank (2), right flank (3), steel strand wires (10), mesh sheet (11), built-in fitting (6) and bottom built-in fitting (7)；Wherein, in the panel (1) It is placed with parallel the first distributing reinforcement (8) and the second distributing reinforcement (9), is opened up between the distributing reinforcement skylight (5), two skylights (5) bilateral symmetry is distributed；It pours to form skylight beam (4) around the skylight (5)；Arrange that bottom is pre- on skylight beam (4) Embedded part (7) arranges built-in fitting (6) in the outside of the distributing reinforcement；The left flank (2) and right flank (3) are symmetrically disposed on face Below plate (1), double-T shaped structure is formed；The mesh sheet (11) is centrally disposed in flank, is distributed a plurality of steel in mesh sheet two sides and twists Line (10)；The steel strand wires (10) are fixed using strand tapered anchorage and anchor plate；Left and right both sides of the chest steel strand wires are pressed respectively to be controlled, up and down Symmetry direction tensioning.

As shown in figure 5, fixing 4 suspension hooks (10) on panel, it is symmetrical set.

The production process of the precast prestressed T plate with skylight of the utility model is as follows:

1, it first cleans die station and has propped up skylight inner template in advance；It arranges simultaneously tension steel strand, disposes steel mesh and built-in fitting；

2, concrete rib is carried out after installing to pour, and skylight external mold is installed again when being poured into panel bottom level line position Plate then successively pours the concrete of T plate panel and skylight beam；

3, mould form removal is removed in overlay film steam curing afterwards for 24 hours, puts a steel strand wires and lifts.

Wherein, answer placement layer by layer when pouring rib base concrete, reduce because the too deep bring of flank vibrate leakiness the problems such as； Using YJM15-1 strand tapered anchorage, the end anchor plate thick using 1050mm high, 380mm wide, 100mm；Every steel strand tension Power is 193KN, and left and right both sides of the chest steel strand wires press left and right direction tensioning symmetrical above and below respectively；Skylight beam arrangement of reinforcement should be calculated individually, skylight The beam of short side direction should add concealed beam；Skylight beam quadrangle should add built-in fitting, convenient for the installation such as later period shutter；Warming and cooling rate The difference of not preferably greater than 20 DEG C/h, surface temperature and environment temperature is no more than 25 DEG C；Pressure resistance is carried out to test block before lifting Degree test, pressure testing intensity reach design/prescribed requirement when side and permit putting a lifting.

Those skilled in the art of the present technique are appreciated that the various operations crossed by discussion in the utility model, method, process In step, measure, scheme can be replaced, changed, combined or be deleted.Further, have in the utility model and begged for It can also be replaced by other steps, measures, and schemes in various operations excessively, method, process, changed, reset, be decomposed, group It closes or deletes.Further, it is in the prior art have in various operations, method disclosed in the utility model, process Steps, measures, and schemes may also be alternated, changed, rearranged, decomposed, combined or deleted.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported Used in other related technical areas, it is also included in the patent protection scope of the utility model.

For those skilled in the art, without departing from the concept of the premise utility, if can also make Simple deduction or replace are done, all shall be regarded as belonging to the protection scope of the utility model.
