Abstract
The invention belongs to the technical field of building construction and provides a construction method for hanging a small precast concrete unit. The method aims to solve the technical problem that a hanging component below an eave and the eave are poured as a whole in the building construction process. The method comprises the specific steps of precasting the concrete unit, and embedding a reinforcement hanging piece according to the shape of the precast concrete unit; reserving reinforcements and pouring holes when the eave or a cantilever beam or an overhanging eave is poured, wherein the size of the reserved pouring hole is identical with that of an upper reinforcement hanging piece of the precast concrete unit; mounting the precast concrete unit by penetrating through the pouring hole to firmly weld the reinforcement hanging piece with the reinforcements reserved in the eave or the cantilever beam or the overhanging eave, erecting small formworks for lower connecting reinforcements, and pouring concrete to enable the precast concrete unit to be connected with the eave or the cantilever beam or the overhanging eave into a whole. The method is easy to operate and low in construction cost, the concrete unit and the eave or the cantilever beam or the overhanging eave can be poured together, and the appearance quality is good.
Description
Technical field
The invention belongs to technical field of building construction, be specifically related to a kind of construction method hanging small precast concrete component.
Background technology
In construction work (especially building in the style of the ancients) construction, often there is the lower extension component of some concrete structures in eaves bight aloft, and these component moulding are unique, and position is generally built in eaves bottom and eaves and is integrated, not easily formwork during construction at the scene, and cannot be together cast-in-place with eaves.
Summary of the invention
The present invention solves lower extension component in building operations under eaves and the technical problem be integrated built by eaves, provides a kind of construction method hanging small precast concrete component.
The technical solution used in the present invention is as follows:
Hang a construction method for small precast concrete component, its concrete steps are:
1) precast unit, and according to the shape embedded reinforcement suspension member of prefabricated concrete component, one end of reinforcing bar suspension member is embedded in prefabricated concrete component, and the other end exposes prefabricated concrete component, ensures anchorage length;
2) reserved steel bar and pouring hole when building eaves, outrigger or cornice, the size of reserved plug hole and the reinforcing bar suspension member on prefabricated concrete component top measure-alike;
3) prefabricated concrete component is installed, by the reinforcing bar suspension member on concrete component top through pouring hole, then the reinforcement welding by reserved in reinforcing bar suspension member and eaves, outrigger or cornice is firm, template is installed afterwards outside concrete component and the reinforcing bar suspension member between eaves, outrigger or cornice, concreting, makes prefabricated concrete component and eaves, outrigger or cornice link into an integrated entity.
Described reinforcing bar suspension member is the reinforcing bar of four band mushroom forest, and bending is made at top.
The diameter of described reinforcing bar suspension member reinforcing bar used is 18-20mm.
Beneficial effect of the present invention:
1. together with concrete component can firmly be cast in eaves, outrigger or cornice by employing the present invention, and impression quality is good.
2. the present invention is simple to operate, and construction costs is low.

Detailed description of the invention
Hang a construction method for small precast concrete component, its concrete steps are:
1) as shown in Figure 1, precast unit 1, and according to the shape embedded reinforcement suspension member 2 of prefabricated concrete component 1, one end of reinforcing bar suspension member 2 is embedded in prefabricated concrete component 1, the other end exposes prefabricated concrete component 1, described reinforcing bar suspension member 2 is generally the reinforcing bar of four band mushroom forest, and top is made bending, ensures anchorage length (bar diameter 18-20mm);
2) as shown in Figure 2,3, reserved steel bar 4 and pouring hole 3 when building eaves, outrigger or cornice, the reserved size of pouring hole 3 and the reinforcing bar suspension member 2 on prefabricated concrete component 1 top measure-alike;
3) as shown in Figure 4,5, 6, prefabricated concrete component 1 is installed, by the reinforcing bar suspension member 2 on concrete component 1 top through pouring hole 3, then by reinforcing bar 4 firm welding reserved in reinforcing bar suspension member 2 and eaves, outrigger or cornice, little section mould plate 5 is installed afterwards outside concrete component 1 and the reinforcing bar suspension member 2 between eaves, outrigger or cornice, concreting 6, makes prefabricated concrete component 1 link into an integrated entity with eaves, outrigger or cornice.
The present invention is simple to operate, and construction costs is low.Together with concrete component can firmly be cast in eaves, outrigger or cornice by employing the present invention, and impression quality is good.
