Embodiment 1

[0033] see figure 1 , figure 2 and image 3 As shown, the embodiment of the present invention provides a template for preparing UHPC prefabricated panels, which is used to prepare UHPC prefabricated panels, including:

[0034] The first panel 1 and the second panel 2 arranged parallel to each other at intervals; the shape and size of the first panel 1 and the second panel 2 are exactly the same. The shapes of the first panel 1 and the second panel 2 are specifically set and customized according to the shape of the UHPC prefabricated panel. The shapes of the first panel 1 and the second panel 2 in this embodiment are preferably rectangular structures, and of course they can also be customized into polygonal structures. or triangular structures. The distance between the first panel 1 and the second panel 2 is specifically set and customized according to the thickness of the UHPC prefabricated board.

[0035] The coaming 3 is sealed and connected around the first panel 1 and...

Embodiment 2

[0041] see figure 1 and figure 2 As shown, a template for preparing UHPC prefabricated panels according to the embodiment of the present invention, the difference between this embodiment and embodiment 1 is that the outer walls of the first panel 1 and the second panel 2 are fixedly connected with an attached vibrator 7 , There are multiple attached vibrators 7, and the multiple attached vibrators 7 are connected to the outer walls of the first panel 1 and the second panel 2 through bolts 5. When the UHPC is poured in the mold, the attached vibrator 7 is started to vibrate, so as to improve the compactness of the UHPC poured in the mold. The attached vibrator 7 is fixed on the outer walls of the first panel 1 and the second panel 2, and manual vibration is not required when pouring the UHPC, which saves labor costs and reduces construction difficulty.

Embodiment 3

[0043] see figure 2 and image 3 As shown, a template for preparing UHPC prefabricated panels according to the embodiment of the present invention, the difference between this embodiment and embodiment 1 lies in: the thickness of the convex steel part 4 and the distance between the first panel 1 and the second panel 2 Similarly, the convex steel part 4 is provided with a through hole, and the first panel 1 and the second panel 2 are provided with a plurality of through holes for installing the convex steel part 4; the convex steel part 4 penetrates the through hole and the The first panel 1 and the second panel 2 are fixedly connected.

[0044] Wherein, the convex steel part 4 includes a first cylindrical boss 41 and a second cylindrical boss 42, and the first cylindrical boss 41 and the second cylindrical boss 42 are separate structures. The diameter of the first cylindrical boss 41 is greater than the diameter of the second cylindrical boss 42, the first cylindrical boss ...

Abstract

The invention discloses a template for preparing a UHPC prefabricated slab and a construction method. The template is used for preparing a UHPC prefabricated slab, belongs to the technical field of building templates, and comprises a first panel and a second panel arranged in parallel at an interval, a coaming, and a plurality convex steel components, wherein the coaming is connected with the periphery of the first panel and the second panel in a sealing manner; a grouting opening is reserved between the first panel and the second panel; the first panel, the second panel and the coaming constitute a cavity structure for accommodating the UHPC prefabricated slab; and the convex steel components are connected between the first panel and the second panel at intervals and are used for reserving mounting holes in the UHPC prefabricated slab. The convex steel components are arranged in the template and are used for reserving mounting holes in the UHPC prefabricated slab; the mounting holes are reserved and formed in the demoulded UHPC prefabricated slab; and the mounting holes and a steel bridge panel are assembled and matched through bolts to improve the connecting strength of the UHPCprefabricated slab and the steel bridge panel.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to a template for preparing UHPC prefabricated panels and a construction method. Background technique [0002] Ultra-high performance concrete, referred to as UHPC (Ultra-High Performance Concrete) is a high-strength, high-modulus, high-ductility ultra-high-performance fiber-reinforced cement composite material, its compressive strength is not less than 130MPa, and the axial tensile strength is not low. The tensile strength can be further enhanced by adding a certain volume of steel fiber and dense reinforcement in UHPC, and the bending and tensile strength can reach 20-40MPa, or even higher. UHPC also has a fairly high density, a high impermeability coefficient, and it is difficult for water to penetrate UHPC. If UHPC is used to replace ordinary concrete structures, it can avoid the phenomenon that ordinary concrete bridge decks are prone to cracking and short life, and...
