Description

A kind of building joint water-tight device

Technical field

The utility model relates to a kind of building joint water-tight devices.

Background technique

Precast concrete refers to the concrete component poured using mold, and the later period is pacified by way of assembled Dress, but precast concrete is in later period assembly will lead to leak due to the generation of piece, traditional waterproof type, be It when prefabricated component assembly, is bonded and is spaced using concrete at piece position, the outside of concrete forms jointing, in jointing Interior filling glass glue is sealed, but the mode of this kind of glass cement filling is easy to fall off in the later period, is led to leak, is passed through coagulation When soil filling, it is poor that thickness is difficult to keep the verticality for unanimously leading to finally to be formed by building.

Based on the above issues, we devise a kind of connection dedicated between precast concrete, and have foot The building joint water-tight device of enough waterproof effects.

The technical problem to be solved by the utility model is to provide a kind of connection dedicated between precast concrete, And the building joint water-tight device with enough waterproof effects.

The utility model is achieved through the following technical solutions:

A kind of building joint water-tight device, including the first frame and the second frame being connected between two precast concretes Frame forms gap between upper and lower two precast concretes, and second frame is placed equidistant in first frame Side forms a gap between first frame and second frame, insulation board is equipped in the gap location, described The surface of first frame and second frame is provided with vertical perforative through-hole, is combined with support device by the through-hole, The support device is supported between upper and lower two precast concretes, is formed by gap location in two precast concretes Filling glass glue, the glass cement are located at the outside of the insulation board, are formed by gap location in two precast concretes and fill out Filled with concrete layer, the concrete layer is located at the inside of the insulation board.

Preferably, the support device is the steel stem of a solid construction, and the diameter of the steel stem is 4mm~6mm, There is retaining ring in the external process of the steel stem, first frame and the second frame are supported on the retaining ring.

Preferably, the support device includes a pipe fitting, and the inside of the pipe fitting is machined with female thread portion, interior by this Threaded portion is combined with upper and lower two screws, and the outer supination of the screw resists precast concrete, and the diameter of the pipe fitting is 4mm~6mm, transition fit between the pipe fitting and the through-hole are machined with the first retaining ring at the outer wall of the pipe fitting, described First frame and second frame are supported on the top of first retaining ring.

Preferably, the insulation board uses XPS insulation board；XPS insulation board, it is added by raw material of polystyrene resin Other supplementary materials and poly inclusion, by heating mixing injecting catalyst simultaneously, then extrusion molding extrusion molding and the hard that manufactures Plastic foamboard.Its scientific name is extrusion molding polystyrene polyfoam for heat insulation (abbreviation XPS), and XPS has perfect closed pore bee Nest structure, this structure allow XPS plate to have extremely low water imbibition (hardly absorbing water), low thermal conductivity coefficient, high pressure resistance, ageing resistance (normal use is almost without aging decomposition).

Preferably, first frame and the second frame are Q235 common carbon structural steel, with a thickness of 4mm~12mm.

Q235 common carbon structural steel is also referred to as A3 steel.

The general plate of common carbon structural steel-is a kind of material of steel.

Q represent be this material yield limit, subsequent 235, just refer to the yield value of this material, in 235MPa Left and right.And its yield value can be made to reduce with the increase of the thickness of material, due to carbon containing moderate, comprehensive performance is preferable, intensity, The performances such as plasticity and welding are preferably cooperated, and purposes is most extensive.

The mounting means of this product is as follows:

The precast concrete for installing lower layer first, then puts the first frame and second above precast concrete Frame, the first frame and the second frame are combined with multiple support devices, and the height of support device is consistent, and is being installed When, need to keep the levelness of lower-layer concrete prefabricated component, it is above-mentioned be installed after, be inserted into insulation board, after insulation board insertion, By the precast concrete on loop wheel machine handling upper layer, alignment installation, after being installed, can filling glass glue and concrete, to After glass cement and concrete are dry and hard, i.e., building is completed.

The beneficial effects of the utility model are: this product is during installation, the height of support device is determined upper and lower two layers and is mixed Gap width between solidifying soil prefabricated component, without being supported by concrete, therefore after installation is complete, upper and lower layer is mixed Gap between solidifying soil prefabricated component is uniform, and the verticality for being finally formed by building is preferable, passes through the complete filling of glass cement, shape At the sealing between precast concrete, inside by concrete layer it is dry and hard after bonded, ensure that upper and lower layer concrete is pre- The firmness of product after installation is complete, the structure of this product is relatively simple, and cost is more cheap, is suitble to promote the use of.
