Abstract

The utility model relates to a building member used in building construction, in particular to an embedded part in a cast-in-place concrete member. The embedded part in the cast-in-place concrete member comprises a steel plate, anchor bolts, and screw rods, wherein the anchor bolts are welded to one side of the steel plate; the screw rods are welded to the other side of the steel plate and are provided with nuts; the steel plate has a plane dimension of 300mm*300mm and a thickness of 10mm; the length of the screw rod is 100mm; four screw rods and four anchor bolts are provided; and the screw rods adopt bolt bars of Phi 8 to Phi 12 and are provided with corresponding nuts. By adopting the embedded part for construction, the position accuracy of the embedded part and the engineering mounting quality are improved completely; and quality problems of coordinate displacement and inaccuracy of embedded parts for a factory building, equipment installation, and a process pipeline and the like are solved; moreover, the embedded part has good social and economic benefits.

Description

Built-in fitting in the cast-in-situ concrete member

Technical field

The utility model relates to the building unit that uses in a kind of building operations, particularly, relates to the built-in fitting in a kind of cast-in-situ concrete member.

Background technology

The crab-bolt leg colligation of built-in fitting or point being welded on the main muscle of post, wall, beam is the set-up mode of built-in fitting routine in the construction, this job practices is in the concrete vibration process, the position of built-in fitting is difficult to guarantee the accuracy of built-in fitting position easily by vibration displacement.Treat in the installation afterwards that majority need pick cutter afterwards, both out-of-flatness was also lack of standardization and pick the built-in fitting of digging out, and majority also do not meet the requirement of design coordinate position, even also having can not find of having, and need carry out bar planting or planted mode such as expansion bolt and handle.So not only influence the presentation quality of construction work, seriously, also influence structural strength, increase workload and waste material simultaneously.

The utility model content

For overcoming shortcoming of the prior art, the purpose of this utility model just provides 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 or needing shortcomings such as bar planting because of the built-in fitting displacement.

For achieving the above object, the utility model adopts following technical scheme:

Built-in fitting in the cast-in-situ concrete member comprises steel plate, crab-bolt and screw rod, and crab-bolt is welded on a side of steel plate, and screw rod is welded on the opposite side of steel plate, has nut on the screw rod;

Preferably, the steel plate planar dimension is 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 the utility model cast-in-situ concrete member has with advantage: adopt built-in fitting of the present utility model to construct, position accuracy rate, the project installation quality of built-in fitting have obtained comprehensive lifting, solved that factory building, equipment are installed and displacement, common quality defect such as inaccurate appear in built-in fitting coordinates such as process pipe easily, had good social benefit and economic benefit.

Among the figure, 1, steel plate; 2, crab-bolt; 3, screw rod; 4, nut; 5, template; 6, cage of reinforcement.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Shown in Fig. 1-2, the built-in fitting in the cast-in-situ concrete member comprises that steel plate 1, crab-

bolt

2 and 3, four crab-bolts 2 of screw rod are welded on the side of steel plate 1, and four screw rods are welded on another side of steel plate 1, have nut 4 on the screw rod 3; Screw rod adopts the shank of bolt of φ 8-φ 12 and is furnished with corresponding nut; The steel plate planar dimension is 300mm * 300mm, and thickness is 10mm; Spiro rod length is 100mm.

As shown in Figure 3, when template 5 is installed, at built-in fitting design coordinate position place, electricity consumption is drilled on 1 corresponding coordinate position of template, get out than screw rod 3 bigger holes, then the screw rod 3 that welds on the built-in fitting therewith the hole to good, again nut 4 is tightened itself and screw rod with spanner at the back side of template, so that built-in fitting and template are fixedly secured, need not to fix, be not subjected to the change of the position of cage of reinforcement 6 when pouring into a mould with cage of reinforcement 6 and change, thereby the position that can guarantee built-in fitting is accurate.

During stripping, only need the mould outer nut 4 of built-in fitting is screwed down earlier, carry out form removable again; After treating form removable, in time nut 4 is screwed on the screw rod 3 effect that is not damaged of protection screw rod.
