Abstract
The invention discloses a construction method for planting wall lacing bars after pre-burying of sleeve assemblies. The method comprises the following steps of: (1) welding sleeves on straight bars of T-shaped mechanical anchorage ribs by using an electric welding machine to form sleeve assemblies, wherein screw threads are formed in the sleeves; (2) before pouring concrete onto a concrete structure, pre-burying the sleeve assemblies into wall lacing bar positions on the concrete structure according to design requirements, and screwing a plugging plastic bolt on the end part of each sleeve; (3) after concrete pouring on the concrete structure is completed, unscrewing the plugging plastic bolts on the end parts of the sleeves, screwing the wall lacing bars into the sleeves, tightening the wall lacing bars with the sleeves by using a spanner, checking qualification by using a torque spanner, and connecting the wall lacing bars and the sleeves into a whole through screw threads; and (4) during building of a later-built wall body, placing the wall lacing bars into mortar joints of the later-built wall body, and bonding the wall lacing bars together with the concrete structure reliably. The method is easy to operate; and the wall lacing bars can be placed into the mortar joints of the later-built wall body to be reliably bonded with the concrete structure.
Description
Technical field
The present invention relates to concrete structure in the building operations and after the build a wall job practices of steel tie between body, relate in particular to embedded sleeve barrel post embedding wall lacing wire job practices.
Background technology
In the existing building construction there be wall lacing wire job practices commonly used:
Pre-buried in 1 concrete structure
1.1 direct preset lace in the concrete structure
The method is in main body concrete column wall work progress, with after the build a wall steel tie of body and concrete structure be embedded in advance in the post wall concrete, after the concrete form removal, wall lacing wire is picked out.This method in picking the cutter process, the structural concrete face is abolished larger, larger to structure influence, substantially be eliminated at present.
1.2 weld lacing wire behind the embedded iron parts in the concrete structure
The method is before frame column and shear wall concreting, and pre-embedded steel slab or the first-class built-in fitting of reinforcing bar after the form removal, weld wall lacing wire at embedded part in advance.The method is had relatively high expectations to weld horizontal, and welding quality is unstable simultaneously, and operation is loaded down with trivial details, and expense is high, inefficiency.
Post embedding wall lacing wire after 2 concrete structure pourings are finished
2.1 boring bonding bar planting method
Boring bonding bar planting method is at need the boring of lacing wire position to be set, and then behind the blowing-out, fills out special-purpose cementitious materials in the hole, then reinforcing bar is put into the hole, and curing conservation 12～48h at normal temperatures.The protection of this method after to the intensity of hole cleaning, drying property, cementitious materials and performance, bar planting requires stricter, is not suitable for simultaneously low temperature He Liang, plate bottom bar planting.
2.2 common expansion bolt welded reinforcement method
This bar planting method is on concrete structure, determines first the lacing wire position, and then expansion bolt is installed in boring, after expansion bolt is fastening, welds lacing wire at the expanding screw tightening latch.This method causes overlap welding multiple deficiency between lacing wire and expansion bolt because limited by expansion bolt mobile jib protruded length, and quality assurance is relatively poor, and one by one welding job efficient is not high.
2.3 learn issued patents technology by retrieval
2.3.1 method for mounting anchor tendon penetrated mechanically
The patent No. is 02229477.5 method for mounting anchor tendon penetrated mechanically, the method is to adopt wall lacing wire one end to be made into enlarged footing and mantle fiber, while overcoat sleeve, at need the boring of lacing wire position is set first during installation, scum silica frost and dust in the cleaning eye are filled in the hole bosom with lacing wire enlarged footing part and sleeve, tighten the nut of lacing wire, make enlarged footing strut sleeve, and be integrated with the concrete structure swelling.This method has reliable in quality, not limited by temperature and weather, and is easy for installation.Shortcoming is to there is no in the market finished product production to sell, and does not possess on-the-spot processing conditions simultaneously, and tailor-made adds man-hour outside the venue, be transported to factory process after whole lacing wires need to being completed after, be transported to again the building site to use, freight volume strengthens, sleeve needs customized simultaneously.Process-cycle is long.
2.3.2 construction method of pull rod expansion screw bolt post embedding wall lacing wire
The patent No. is the construction method of pull rod expansion screw bolt post embedding wall lacing wire of ZL200810151890.0, the method is to hole at the concrete structure of lacing wire position, the special pull rod expansion screw bolt of packing in the hole, wall lacing wire is inserted in the countersunk head hollow bolt bar of pull rod expansion screw bolt, by the nut that screws pull rod expansion screw bolt make between wall lacing wire and the pull rod expansion screw bolt and wall lacing wire and concrete structure hole between swelling be integral, the method is simple to operate, accurate positioning, applicability are strong.But still exist between expansion bolt and concrete structure bond stress poor, rear boring perturbations, and the easy defective of damaged structure reinforcing bar in the boring procedure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and do not damage that concrete structure, steady quality are reliable, Technological Economy, later stage embedded sleeve barrel assembly post embedding wall lacing wire job practices easy for installation.
Embedded sleeve barrel assembly post embedding wall lacing wire job practices of the present invention, it may further comprise the steps:
(1) adopts electric welding machine sleeve to be welded on the straight-bar of T shape mechanical anchor muscle and form sleeve assembly, in described sleeve, be provided with screw thread;
(2) before the concrete structure pouring concrete, sleeve assembly is embedded in the wall lacing wire position of concrete structure by designing requirement, and screws on shutoff plastics bolt at each sleeve ends;
(3) after the concreting of concrete structure is finished, screw out with the shutoff plastics bolt of screwdriver with sleeve ends, then wall lacing wire is screwed in the sleeve, with spanner wall lacing wire and sleeve are tightened again, final force square spanner passed examination makes wall lacing wire be connected by screw thread with sleeve;
(4) after build a wall body when building by laying bricks or stones, in the mortar joint of the body of building a wall after wall lacing wire is placed on, make it to form reliable drawknot with concrete structure.
Adopt the inventive method under the prerequisite of ensuring the quality of products, by structure and the wall lacing wire 4 that sleeve 1 and mechanical anchor muscle 2 form, both can adopt respectively at the scene the on-the-spot processing of common welding machine and small-sized die head threading machine, also can be in typing processing outside the venue.Only need one screwdriver, got final product spanner and to the torque spanner of inspection usefulness during installation.Simple to operate, be not subjected to temperature and weather effect, installation quality reliable, check that mechanical property convenient, wall lacing wire is reliable and stable, simultaneously instant use can be installed at any time, it is very convenient to construct.Adopt this method wall lacing wire 4 can be placed in the mortar joint of body of wall 7, make it to form reliable drawknot with concrete structure.
