Abstract
The invention belongs to the technical field of civil engineering, and in particular, relates to a stainless steel connecting piece for a prefabricated concrete sandwich insulation wall. The connecting piece consists of a stainless steel rod, an inverted conical cross rib and a lantern ring. The stainless steel connecting piece is characterized by adopting the stainless steel rod as a main body of the connecting piece, adopting the inverted conical cross rib to enhance the anchoring performance of the connecting piece in concrete and adopting the lantern ring matched with the insulation layer in thickness to conveniently mount the connecting piece. The stainless steel rod body and the inverted conical cross rib of the connecting piece are integrated cast by a mold; the lantern ring adopts a thermoplastic material; and a thermoplastic process is adopted to mold after the molding of the stainless steel rod body and the cross rib. The connecting piece is low in heat conducting coefficient and excellent in fire resistance and durability, and can be used for connecting inner and outer concrete slabs of the prefabricated concrete sandwich insulation wall to form a novel sandwich insulation wall integrating the structure with the function.
Description
Technical field
The invention belongs to field of civil engineering, be specifically related to a kind of stainless steel adapting piece for precast concrete sandwich heat preserving wall body.
Background technology
There are some researches show, the energy consumption that building external watch box system (exterior wall) causes accounts for more than 80% of building energy consumption.Improving the energy-saving horizontal of building external watch box system, is the important measures reducing building energy consumption.The energy-saving heat preserving structure of external wall mainly can be divided three classes, that is: Surgery therapy, inside holding and sandwich heat preservation.Surgery therapy heat insulating material is arranged at the energy-saving structure formed outside exterior wall, and this structure exists heat insulating material large, poor durability affected by environment, easily the deficiency such as to come off.Inside holding is energy-saving structure heat insulating material being arranged at inner side of outer wall and being formed, and this structure is unfavorable for interior decoration, fragile.Sandwich heat preservation is the energy-saving structure being arranged by heat insulating material and formed in the middle of exterior wall, this structure ensure that heat insulating material is not subject to the impact of external environment condition and interior decoration, can realize the same life-span with structure, be the main development direction of building external wall energy-saving thermal insulation structure from now on.
Connector is the critical component connecting precast concrete sandwich heat preserving wall inside and outside leaf concrete slab, make the two formation overall, and it mainly bears starting and shear action between two panels concrete slab.Therefore, connector should possess carrying and heat insulation dual-use function.At present, conventional in engineering precast concrete sandwich heat preserving wall body connector mainly comprises FRP connector and stainless steel adapting piece two class.Wherein, the heat-proof quality of FRP connector is good, intensity is high, but fire resistance and alkaline resistance properties deficiency.Stainless steel adapting piece then has good heat-proof quality, fire resistance and endurance quality simultaneously, is applicable to fire resistance rating and the higher precast concrete sandwich heat preserving wall body of life requirement.From the documents and materials of system reviews, existing stainless steel adapting piece adopts truss-like or the form such as sheet, ring-type substantially.In general, existing stainless steel adapting piece installation is comparatively complicated, material usage is comparatively large, price is higher.
Given this, a kind of fire resistance and endurance quality better, easy for installation, cheap, the stainless steel adapting piece that is applicable to precast concrete sandwich heat preserving wall body urgently researches and develops.
Summary of the invention
The object of the present invention is to provide a kind of stainless steel adapting piece for precast concrete sandwich heat preserving wall body.
A kind of stainless steel adapting piece for precast concrete sandwich heat preserving wall body that the present invention proposes, be made up of stainless steel bar 1, back taper cross rib 2 and the collar 3, wherein: stainless steel bar 1 is connector main body, back taper cross rib 2 is fixed at stainless steel bar 1 two ends, in the middle part of stainless steel bar 1, cover has the collar 3 matched with insulation layer thickness, the described collar 3 is made up of collar cap 7, cover ring body 8 and thread belt 9, and cover ring body 8 top is provided with collar cap 7, and cover ring body 8 surface is provided with thread belt 9; During use, stainless steel bar 1 cover has the part of the collar 3 to be positioned at insulation layer 5, stainless steel bar 1 top is positioned at body of wall siphonal lobe concrete slab, and stainless steel bar 1 bottom is positioned at body of wall internal lobe concrete slab, and the length of stainless steel bar 1 in concrete slab meets anchorage length requirement; Described back taper cross rib 2 is for improving the anchoring property of stainless steel bar in concrete.
In the present invention, connector main body stainless steel bar adopts stainless steel material, and have good fire resistance, endurance quality and heat-proof quality, intensity is higher, is applicable to high fire resistance rating and high-durability precast concrete sandwich heat preserving wall body.
In the present invention, stainless steel bar main body and back taper cross rib adopt mould formed by integrally casting shaping, and the collar adopts thermoplastic, and stainless steel bar main body and the shaping rear employing thermoplastic processes of cross rib shaping.Manufacture craft is simple, stable performance, with low cost.
In the present invention, the surface of connector main body stainless steel bar is comparatively smooth, and is difficult between concrete form reliable anchoring.Therefore, the back taper cross rib anchoring structure in connector two ends optimal design.The experimental study that inventor completes shows, this structure significantly improves the anchoring property of connector.
Beneficial effect of the present invention is:
(1) present invention achieves apply precast concrete sandwich heat preserving wall body under fire resistance rating and the higher condition of life requirement, and heat-insulation system can realize the same life-span with agent structure.
(2) stainless steel adapting piece that the present invention relates to is functional, easy for installation, with low cost.
Accompanying drawing explanation
Fig. 1 is stainless steel adapting piece schematic diagram of the present invention.
Fig. 2 is the structural representation of the collar 3 of the present invention.
Fig. 3 is the installation constitution figure of stainless steel adapting piece in precast concrete sandwich heat preserving wall body.
Number in the figure: 1 be stainless steel bar, 2 be back taper cross rib, 3 be the collar, 4 be body of wall siphonal lobe concrete slab, 5 insulation layers, 6 are body of wall internal lobe concrete slab, 7 be collar cap, 8 for cover ring body, 9 is for thread belt.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment 1, stainless steel adapting piece is made up of stainless steel bar 1, back taper cross rib 2 and the collar 3, and its structure as shown in Figure 1.The collar 3 is made up of collar cap 7, cover ring body 8, thread belt 9, and adopt thermoplastic and make one by thermoplastic processes, its structure as shown in Figure 2.The collar 3 around and be fixed in the middle part of connector.
In precast concrete sandwich heat preserving wall body manufacturing process, first build body of wall siphonal lobe concrete slab 4, and Fast Installation insulation layer 5, before concrete initial set, stainless steel adapting piece is inserted in siphonal lobe concrete slab, until the collar 3 of connector is positioned at the design attitude place of insulation layer through insulation layer.Then, treat that siphonal lobe concrete slab reaches predetermined strength after-pouring body of wall internal lobe concrete slab 6.After siphonal lobe concrete slab equal maintenance to design strength in body of wall, namely complete body of wall make, as shown in Figure 3.
