Description

Anchor sleeve for a manhole}

The present invention relates to an anchor sleeve for a manhole, and more particularly, a connecting means such as an eye bolt connecting a lifting cable of a crane to lift and move a manhole when constructing a heavy manhole can be fitted to the manhole wall. The present invention relates to an anchor sleeve for a manhole inserted into an outer circumferential surface of a wall when manufacturing a manhole.

In general, the manhole is a hole made for access to the basement of the road, and is used for contact with ventilation or conduit, and there are two manufacturing methods that are manufactured by pouring in the field or separately manufactured and transported and assembled at the factory. In particular, in the case of a method of assembling the ready-made construction in the field as shown by the reference numeral 110 in Figure 1, the construction position of each member divided into the upper sphere (110a), vertical sphere (110b), lower sphere (110c) They are then stacked and assembled one after the other.

Therefore, each of the spheres (110a, 110b, 110c) should be able to move smoothly despite the weight (weight) of 600 to 1000kg, the manhole 110 by walking the lifting cable 150 of the transport device, such as a crane Connection means 120 such as an eye bolt to lift the manhole 110 is fitted to the wall 111 to be coupled.

To this end, an anchor sleeve 101 for inserting and fixing the connecting means 120 is embedded in the middle part of the wall 111 in the manhole 110 wall 111 so as to be exposed to the outer circumferential surface of the wall 111. The outer shape of the sleeve 101 is flat with the miner except for the head 104, and thus the anchor sleeve 101 due to the weight of the manhole 110 transmitted to the anchor sleeve 101 via the connecting means 120. ) Does not greatly resist the tension or rotational moment acting outside the wall 111, and is easily damaged or deformed, resulting in a loss of support for the connecting means 120, thereby connecting means 120 And the fastening force of the anchor sleeve 101 is lowered and the connecting means 120 is separated from the anchor sleeve 101 during transport of the manhole 110, thereby causing a large accident, or there is a problem in that normal use is impossible due to the accident.

Accordingly, as shown in FIG. 2, when the manhole 110 is manufactured, a tensile force applied through the connecting means 120 by welding a reinforcing member 130 formed by cutting reinforcing bars or the like to the inner portion of the anchor sleeve 101. In order to greatly increase the resistance of the anchor sleeve 101 to the rotational moment, but it is necessary to weld the reinforcing member 130 to the anchor sleeve 101 one by one, the welding process is added to the overall work efficiency and economic efficiency of the manhole construction It had a problem of greatly deteriorating.

In addition, in the case of using the push rod as shown in Figure 7 that is forcibly fitted to the anchor sleeve as a connecting means when the puller is used to pull out the push rod from the anchor sleeve after the construction is completed, the support of the puller is on the outer surface of the manhole wall Since the direct contact, withdrawal of the indentation rod is not made smoothly, there was also a problem such that the outer surface of the wall pressed by the support is damaged.

The present invention has been proposed to solve the problems of the conventional anchor sleeve as described above, by increasing the binding force of the anchor sleeve to the manhole wall to the external force transmitted through the connecting means when lifting the manhole with the lifting cable of the crane Its purpose is to increase the resistance to damage and thus reduce the damage or deformation caused by external forces, so as to prevent the loss of work efficiency resulting from the suspension of use due to accidents or concerns that may occur due to separation from the connecting means. have.

In addition, when using the press-fit rod pushed into the insertion hole as a connecting means, there is another object to prevent the manhole wall is damaged by the puller used to pull out the push rod from the insertion hole.

The present invention, in order to achieve the above object, a single rod form body; An insertion hole formed at one end of the body and having an entrance exposed to an outer circumferential surface of the manhole wall to insert and fix the connecting means; And a plurality of binding ribs protruding from the outer circumferential surface of the body to increase the binding force with the manhole wall.

In addition, the body preferably further includes a reinforcing member fastening hole penetrated so as not to interfere with the connecting means inserted into the insertion hole fixed to the portion buried in the manhole wall.

In addition, the body preferably further includes a plurality of locking grooves formed to hang the support of the puller on the end surface of the one end formed with the insertion hole inlet.

According to the anchor sleeve for the manhole of the present invention, not only protruding a plurality of binding ribs on the outer periphery of the body of the anchor sleeve, but also through the fastening hole formed in the body to form a rod-shaped reinforcing member in a direction perpendicular to the longitudinal direction of the body. By inserting, it is possible to increase the binding force between the body and the wall buried in the manhole wall and to increase the resistance to tension or moment due to external force applied through the connecting means, thereby reducing damage or deformation caused by external force. Will be. Therefore, when the anchor sleeve is damaged or deformed, the connection means can be easily disconnected to prevent the decrease in work efficiency due to the accident or the risk of the accident, which can improve safety, productivity or economic efficiency of the entire manhole construction process. It becomes possible.

In addition, even when the press rod is used as a connecting means fixed to the insertion hole can support the support of the puller in the engaging groove formed on the end surface of the body can be supported to prevent damage to the manhole wall due to the use of the puller.

Hereinafter, a manhole anchor sleeve according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The inlet 6, which is open to one end, that is, the outer end, is embedded in an edge portion adjacent to the outer circumferential surface of the manhole wall 11 as shown to be exposed to the outer circumferential surface of the manhole wall 11.

At this time, the insertion hole 5 may preferably form the female screw portion 21 along the inner circumferential surface so as to insert and fix the connecting means 20 of the bolt shape such as the eye bolt shown in FIG. As shown in FIG. 7, the inner circumferential surface may be made small or tapered so that the inner circumferential surface may be clamped so as to fix the connecting means 20 which is not threaded, such as a press-fit rod.

In addition, the plurality of binding ribs 7 is a means for increasing the binding force between the anchor sleeve 1, that is, the body 3 and the manhole 10 wall 11, as shown in Figs. , Protrudes in various forms on the outer circumferential surface 15 of the body 3, is disposed in the circumferential direction at regular intervals in the longitudinal direction on the outer circumferential surface 15 of the body 3, as shown in FIGS. 4 and 6. Ring-shaped ribs 7a, straight ribs 7b arranged longitudinally at regular intervals on the outer circumferential surface 15 so as to traverse a plurality of ring-shaped ribs 7a, and similar shapes and sizes to the heads 4 It consists of a combination of a flange-like rib (7c) protruding radially on one side of the furnace outer peripheral surface (15).

Meanwhile, as shown in FIGS. 3 and 6, the reinforcing member fastening hole 9 is a hole formed through a portion of the body 3 buried in the wall 11 of the manhole 10, and is formed in the anchor sleeve 1. In order to support the tension or rotation moment acting on the anchor sleeve 1 through the connecting means 20 when the lifting cable 50 is hooked to the coupled connecting means 20 to lift the manhole 10 by the crane. The reinforcing member 30 coupled to the anchor sleeve 1 is fitted.

At this time, the reinforcing member 30 has a length long enough to receive a force capable of resisting the external force applied to the anchor sleeve 1, as shown in Figure 3, in particular, the reinforcing member fastening hole (9) is inserted The reinforcing member 30 is to be sufficiently spaced inward from the bottom of the insertion hole 5 so as not to cause interference, such as contact with the connecting means 20 is inserted into the insertion hole (5).

In addition, the plurality of engaging grooves 19 are shown in Figs. 4 to 7, one end of the body 3, that is, the outer end end surface 17 of the inlet 6 of the insertion hole 5 is formed It is formed concave and arranged in a circle around the insertion hole inlet (6), as shown in Fig. 7 pulls the connecting means 20 of the same shape as the press-fit rod is inserted into the insertion hole (5) (40) The supporter 41 of the puller 40 is inserted and fixed when it is pulled out by ().

Now, the operation of the anchor sleeve 1 for the manhole according to the preferred embodiment of the present invention configured as described above will be described.
