Abstract

The invention relates to a building component used in building construction, in particular to an embedded part for a cast-in-place concrete component. The embedded part for the cast-in-place concrete component comprises a steel plate, four anchor bolts and four bolt rods, wherein the anchor bolts are welded on one side of the steel plate; the bolt rods are welded on the other side of the steel plate; a nut is arranged on each bolt rod; the plane dimension of the steel plate is 300mm*300mm, and the thickness of the steel plate is 10mm; the length of each bolt rod is 100mm; the diameters of the bolt rods are Phi 8 to Phi 12, and the bolt rods are matched with corresponding nuts. The embedded part provided by the invention are adopted for construction, so that the position accuracy of embedded parts and the engineering mounting quality are comprehensively improved; the common quality problems that the coordinates of the embedded parts of workshop and equipment mounting, process pipelines and the like are liable to displace, and are inaccurate and the like are solved; the embedded part for the cast-in-place concrete component has a good social benefit and a good economic benefit.

Description

Built-in fitting in a kind of cast-in-situ concrete member and construction method thereof
Technical field
The present invention relates to the building unit used in a kind of building operations, particularly, relate to the built-in fitting in a kind of cast-in-situ concrete member.
Background technology
It the main muscle crab-bolt leg colligation of built-in fitting or point being welded in post, wall, beam is the set-up mode of built-in fitting routine in construction, this construction method is vibrated in process concrete, the position of built-in fitting, easily by vibration displacement, is difficult to the accuracy ensureing built-in fitting position.Treat in installation afterwards, most needs picks cutter afterwards, and picks and dig out the built-in fitting come both out-of-flatness was also lack of standardization, and majority does not also meet the requirement of design coordinate position, and what even have also can not find, and needs carry out bar planting or plant the mode process such as expansion bolt.So not only affect the presentation quality of construction work, seriously, also affect structural strength, increase workload simultaneously and waste material.
Summary of the invention
For overcoming shortcoming of the prior art, object of the present invention is just to provide the built-in fitting in a kind of novel cast-in-situ concrete member, and this embedded part structure is simple, easy for installation, avoids causing structural deterioration because of built-in fitting displacement or needing the shortcomings such as bar planting.
For achieving the above object, the present invention adopts following technical scheme:
Built-in fitting in cast-in-situ concrete member, comprises steel plate, crab-bolt and screw rod, and crab-bolt is welded on the side of steel plate, and screw rod is welded on the opposite side of steel plate, with nut on screw rod;
Preferably, steel plain is of a size of 300mm × 300mm, and thickness is 10mm;
Preferably, spiro rod length is 100mm;
Preferably, the quantity of screw rod is four, and the quantity of crab-bolt is four;
Preferably, screw rod adopts the shank of bolt of φ 8-φ 12, and nut adopts the nut of respective model.
Built-in fitting in cast-in-situ concrete member of the present invention has the following advantages: adopt built-in fitting of the present invention to construct, position accuracy rate, the project installation quality of built-in fitting obtain comprehensive lifting, solve factory building, equipment installs and displacement, the common quality defect such as inaccurate easily appear in the built-in fitting coordinate such as process pipe, has good Social benefit and economic benefit.

In figure, 1, steel plate; 2, crab-bolt; 3, screw rod; 4, nut; 5, template; 6, cage of reinforcement.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1-2, the built-in fitting in cast-in-situ concrete member comprises steel plate 1, crab-bolt 2 and screw rod 3, four crab-bolts 2 and is welded on a side of steel plate 1, and four screw rods are welded on another side of steel plate 1, with nut 4 on screw rod 3; Screw rod adopts the shank of bolt of φ 8-φ 12 and is furnished with corresponding nut; Steel plain is of a size of 300mm × 300mm, and thickness is 10mm; Spiro rod length is 100mm.
As shown in Figure 3, when template 5 is installed, at Designing of Pre-embedded Pieces in Concrete Structures coordinate position place, electricity consumption is drilled on the corresponding coordinate position of template 1, get out the hole more bigger than screw rod 3, then the screw rod 3 that built-in fitting welds therewith hole to good, again itself and screw rod are tightened by the back side spanner of nut 4 in template, built-in fitting and template are fixedly secured, without the need to fixing with cage of reinforcement 6, not being subject to the change of the position of cage of reinforcement 6 when pouring into a mould and changing, thus can guarantee that the position of built-in fitting is accurate.
During stripping, only the mould outer nut 4 of built-in fitting first need be screwed down, then carry out form removable; After form removable, in time nut 4 is screwed on screw rod 3, protection screw rod is not damaged effect.
