Description
Technical field
The utility model relates to a kind of mounting tool of built-in fitting, and especially a kind of nuclear power station wall body built-in fitting is installed braced structures, belongs to technical field of building construction.
Background technology
The embedded part that distributes by predetermined rule need to be installed when the nuclear power station body of wall is constructed, thereby rely on foundation for later equipment provides support welding.In order to guarantee the safe and reliable of later stage arranging apparatus, require the embedded part depression to be controlled in the 1cm.
Mainly containing two kinds of method for supporting in the installation of embedded parts at present, is respectively directly to add the mortar pad method with mortar pad method and push rod.
Be when built-in fitting is attached on the template with the mortar pad method directly, select mortar pad according to the embedded part steel plate to the spacing of body of wall stud, mortar pad is clamped between built-in fitting steel plate and the stud.The method significant limitation arranged: 1) spacing between embedded part steel plate and the stud is not fixed value, so most suitable mortar pad can not be arranged; 2) in concrete placement, vibrating head is as easy as rolling off a log to vibrate to mortar pad, and at this moment a lot of mortar pads just easily come off or be loosening, causes the built-in fitting depression.
Push rod adds the mortar pad method, need to shift to an earlier date specially a prefabricated push rod, wherein: push rod length=thickness of wall body-built-in fitting steel plate thickness+welded plate thickness-mortar pad thickness.This reinforcement means also has significant limitation: process in advance push rod and will weld with welded plate, secondly to reserve two apertures on the welded plate, mortar pad is also customized specially, want advance reservation to roll silk around the mortar pad, in order to carry out colligation with welded plate, operation is loaded down with trivial details, is not easy to construction.
The utility model content
The technical problems to be solved in the utility model is: propose a kind of nuclear power station wall body built-in fitting of built-in fitting depression that can effectively prevent braced structures is installed.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of nuclear power station wall body built-in fitting is installed braced structures, comprises the built-in fitting that is made of dowel and anchor block, the one group of support bar that is used for constraint built-in fitting dowel and the frame construction cage of reinforcement that is made of the vertical and horizontal reinforcing bar; Described one group of support bar is a pair of in twos, and cross weld is fixed on the side inside that described cage of reinforcement is settled built-in fitting in length and breadth, forms by precalculated position groined type structure spaced apart; The hollow sash of described groined type structure and the gabarit of described dowel match, and described built-in fitting passes and welds the mode that is constrained in described hollow sash and is positioned at described cage of reinforcement with dowel.
Like this, because the welding of the cage of reinforcement of support bar and frame construction is connected, and the support bar that is close to respectively around the dowel of built-in fitting weldering connects constraint, even therefore construct at body of wall and be subject to various deformation factor impacts in the process, also can guarantee the depression of built-in fitting is controlled at tolerance, provide reliable welding to rely on foundation thereby settle for the equipment in later stage.
To further improvement in the technical proposal be: described cage of reinforcement is fixed with push rod away from the side welding of settling built-in fitting, and an end and described built-in fitting that described push rod stretches in the described cage of reinforcement are connected.Like this can be on the basis of support bar constraint, the effect of shoring by push rod further prevents the built-in fitting depressed deformation.
Further improvement to technique scheme is: the nuclear power station wall body built-in fitting is installed braced structures and is also comprised be used to the ground rebar that satisfies the built-in fitting grounding requirement; One end of described ground rebar is welded on the described built-in fitting dowel, and the other end is welded on the described cage of reinforcement.
To further improving again of technique scheme be: described ground rebar is U-shaped round steel, and each built-in fitting diagonal angle is welded with two U-shaped round steel.
The beneficial effect that the utility model brings is: the nuclear power station wall body built-in fitting is installed the support bar of braced structures and the cage of reinforcement welding of frame construction is connected, and the support bar that is close to respectively around the dowel of built-in fitting weldering connects constraint, can guarantee the depression of built-in fitting is controlled at tolerance, settling for the equipment in later stage provides reliable welding to rely on foundation; And cage of reinforcement is fixed with push rod away from the side welding of settling built-in fitting, an end and built-in fitting that push rod stretches in the described cage of reinforcement are connected, therefore can be on the basis of support bar constraint, the effect of shoring by push rod further prevents the built-in fitting depressed deformation; Simultaneously owing to adopting ground rebar can satisfy the grounding requirement of on-the-spot built-in fitting.
Description of drawings
Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
The specific embodiment
Embodiment one
The nuclear power station wall body built-in fitting of the present embodiment is installed braced structures as shown in Figure 1, comprises built-in fitting 3, one group of support bar 2 and cage of reinforcement 1, and wherein built-in fitting 3 is provided with dowel and anchor block.
The thickness of wall body of the present embodiment is 500mm, built-in fitting 3 is of a size of 250mm * 250mm, built-in fitting 3 is provided with four dowels, each dowel length is 225mm, the frame construction that cage of reinforcement 1 consists of for the vertical and horizontal reinforcing bar, support bar 2 adopts the reinforcing bar of φ 14, and support bar 2 is welded on respectively on the reinforcing bar of vertical and horizontal of cage of reinforcement 1.
