Abstract

The utility model relates to a T-shaped pre-buried self-exfoliated anchor device used in construction field. The structure of the utility model is that a vertical screw is welded on a chassis, and the middle part and the lower part of the screw are sleeved with a casing, while the upper part of the screw is provided with a liner and a nut. The utility model can take the place of original steel bar anchor devices, and is suitable to anchor outer scaffolds, fix a large template ground anchorage, or anchor tower crane wall-attaching pipes, etc. The utility model can be combined with steel pipes, channel steels, and steels in H-shape to form different anchorages. The utility model has the advantages of fast positioning, convenient construction, and steel and labor saving; furthermore, the arrangement and the disassembly of the utility model are fast, so the utility model has high work efficiency, and can be repeatedly used, saving steel resources consumed by the original steel anchors, and saving the labor force and energy used in cutting the protrusive ends of steel bar anchors, with significant economic efficiency.

Description

The pre-buried self-falling type anchorage of T type

Technical field

The utility model relates to a kind of anchoring apparatus of building operations industry, the pre-buried self-falling type anchorage of T type of usefulness such as specifically a kind of anchoring scaffold, large form or tower crane attached wall pipe.

Background technology

At present, in the construction of highrise building, the anchorage style that is connected of constructions such as external scaffolding, large form or tower crane attached wall pipe and agent structure, normally in concrete slab a pre-buried bar reinforcement that bends moulding as ground tackle, submerging of reinforcing bar partly realized the location of ground tackle with concrete binding, the exposed parts of reinforcing bar is used for the anchoring object.After the Structural Engineering construction of highrise building is finished, also need with of the exposed parts excision of modes such as electrogas welding, so that follow-up construction is convenient in surfacing with these embedded bar ground tackles.The used reinforcing bar of anchorage of reinforcement is 1.12 meters, 1.78 kilograms of weight, and cost is 6 yuan.The highrise building of one 30,000 square meter of building needs about 3 tons of anchorage of reinforcement.The annual highrise building in the whole nation has several ten thousand, and only the reinforcing bar of a consumption of anchorage of reinforcement just reaches more than tens thousand of tons.Because this anchorage of reinforcement can only disposablely use, the part of imbedding has just been stayed in the building forevermore, and the exposed parts of clipping has just become waste product, therefore this anchorage of reinforcement has many wastes of aspects such as material, the energy and fund, and have the location inaccurate and be anchored, problem such as the excision recruitment is more.

The utility model content

The purpose of this utility model just provides a kind of accurate positioning, is provided with conveniently and the pre-buried self-falling type anchorage of repeatedly used T type, to reduce construction cost, saves working material, the energy and fund.

The utility model is achieved in that the pre-buried self-falling type anchorage of this T type is to be welded with upright bolt on the chassis, and the middle and lower part of bolt is connected to sleeve pipe, and the top of bolt is connected to pad and nut.Chassis and bolt form the pedestal of an inverted T shape structure, and the sleeve pipe on the bolt is used to isolate concrete, and pad and nut cooperate with bolt, are used to be anchored member.

The using method of this self-falling type anchorage is: before concrete slab is built, set and place ground tackle earlier on cast-in-place template, follow closely on the cast-in-place template of ground tackle chassis periphery with nail, the setting position of chassis on template accurately located; Slip joint casing on the bolt of ground tackle then, the upper end of sleeve pipe is basic concordant with the end face of concrete slab; After having brushed release agent on the chassis of cast-in-place template and ground tackle, can carry out the pouring construction of concrete slab.Treat concrete slab build finish and have certain degree of hardness after, to need again to be inserted on the ground tackle bolt that exposes on the concrete slab after the member perforate of anchoring, or, insert pad with on the inserting bolt after the anchor clamps clamping, use nut screwing clamping, realize that thus the anchor of associated components is fixed.Pre-buried ground tackle in concrete is on the one hand because the existence of sleeve pipe makes ground tackle bolt and concrete isolated; On the other hand, the release agent of brushing on the base has also prevented the bonding of ground tackle base and concrete slab.Owing to the existence of this two aspects reason, though make this ground tackle reached in concrete pre-buried not with the effect of concrete bonding.When the member that removes nut on the screw rod and institute's anchoring and after removing cast-in-place template, this ground tackle just can come off under action of gravity voluntarily, has constituted a kind of pre-buried self-falling-off type building operations ground tackle thus.

The alternative original anchorage of reinforcement of the utility model is applicable to anchoring external scaffolding, fixing large form earth anchor or carry out the anchoring of tower crane attached wall pipe etc., and can combines with steel pipe, channel-section steel, i iron etc., forms various forms of anchors.The utlity model has accurate positioning, easy construction, speed of application fast, save steel, save advantages such as artificial, its setting and dismounting speed are fast, the work efficiency height, outstanding feature is to have enough to meet the need use repeatedly, therefore can save the steel resources that original anchorage of reinforcement consumes after using, also can save the used artificial and energy of cutting anchorage of reinforcement exposed junction simultaneously, economic benefit is very remarkable.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, this ground tackle is perforate on chassis 1, after the inserting bolt 2, bolt root and chassis 1 is welded together.PVC plastic bushing 3 is socketed on the bolt 2, and the top of bolt 2 is connected to a square steel shim 5, and the nut 6 that spins.

For ease of making, chassis 1 is preferably designed as regular polygon or rectangle, as square.Each limit on chassis 1 can be designed to the sloping limit at 40-50 ° of angle, so just is more conducive to separating of chassis 1 and concrete slab.

For satisfying the anchoring of special shape member, need to use special shaped steel anchor clamps, a kind of shaped steel anchor clamps 4 among Fig. 1 are to make with one section channel-section steel, on the channel-section steel base plate, have the strip hole of being convenient to regulate, shaped steel anchor clamps 4 are socketed on the bolt 2, behind clamping or connecting elements, by pad 5 and nut 6 lockings.

Claims

1, the pre-buried self-falling type anchorage of a kind of T type is characterized in that this ground tackle is that (1) goes up the upright bolt (2) of welding on the chassis, and the middle and lower part of bolt is connected to sleeve pipe (3), and the top of bolt is connected to pad (5) and nut (6).

2, the pre-buried self-falling type anchorage of T type according to claim 1 is characterized in that chassis (1) is regular polygon or rectangle, and each limit is the sloping limit at 40-50 ° of angle.

3, the pre-buried self-falling type anchorage of T type according to claim 1 and 2 is characterized in that being socketed with shaped steel anchor clamps (4) on bolt (2).
