埋件錨固方式

The anchoring of embedded part

埋件的錨固有兩種方式，一種是用縮短螺栓錨固埋件，這樣漲殼式錨桿的錨固力受到主不雅條件的解放較大，臨時(shí)披露在空氣中，抵抗侵蝕的能耐也較差?？v然在相同混凝土上接管相同的縮短螺栓，錨固力也有很大的變換，這主若是由工人的施工操作原因造成的質(zhì)質(zhì)變換。另一種錨固埋件的方式便是接管化學(xué)螺栓錨固埋件，用飽以及樹(shù)脂將錨桿以及混凝土堅(jiān)貞粘接在一起，同時(shí)樹(shù)脂也起到呵護(hù)錨桿不受侵蝕的浸染。

There are two ways for the anchoring of embedded parts: one is using expansion bolt, but the anchoring force of expansion shell bolt will suffer larger restrictions of objective conditions, and corrosion resistance will become worse as well when it exposed in the air. The anchorage force has a great change even if it is adopted the same expansion bolt in the same concrete , that is the quality change mainly caused by worker’s operation. Another is using embedded parts with chemical anchor bolts，which use the saturated resin to firmly splice the anchor bolt and concrete together , meanwhile, resin can protect bolts from corrosion.

錨固膠的種類

Types of Anchor adhesive

化學(xué)螺栓個(gè)別接管的錨固膠有兩大規(guī)范，一種為等量攪渾型；另一種為快干劑型，即在錨固膠中加之未必比例催化劑使錨固膠可能在規(guī)定的光陰內(nèi)達(dá)到預(yù)約的強(qiáng)度。

Anchor adhesive which is used to chemical anchor bolt has two type: one is balanced mix type, the another is flash dry type, it means that add the certain proportion of the catalyst to the anchor adhesive to make it can run up to the intensity within specified time.

修筑化學(xué)螺栓錨固埋件的施工工藝

The construction technology of steel panel anchoring by chemical anchor bolt

1

清理下層，定位放線，在錨固點(diǎn)的需要位置將混凝土的外表清理平展，在艱深粘土燒結(jié)磚上施工化學(xué)螺栓，其強(qiáng)度將著落，可能使埋件的平展。

Base cleaning and positioning, cleaning and flattening the concrete surface at the required anchoring point, anchoring the chemical anchor bolt into the ordinary clay sintered brick will reduce its strength to flatten the steel panel.

2

鉆孔的位置距混凝土的邊緣5D(D為錨桿的直徑)，如在非凡狀態(tài)下，若需要將混凝土內(nèi)的鋼筋切斷，必須經(jīng)由無(wú)關(guān)結(jié)構(gòu)工程師的應(yīng)承方可施工。

The position of the drilling hole to the edge of the concrete is 5D (D it means for the diameter of the anchor), if in the special circumstances, the rebar in the concrete need to be cut after approval by the engineer.

3

鉆孔要以及混凝土墻面垂直，使錨固栓以及埋鐵垂直。

Drilling hole should be perpendicular to concrete wall as well as the anchor bolt and embedded steel plate.

4

化學(xué)錨固埋件對(duì)于在混凝土上的鉆孔直徑要求也是******嚴(yán)厲，鉆孔的直徑過(guò)小起不到錨固膠應(yīng)該有的浸染。個(gè)別鉆孔的直徑要比錨桿的直徑大4~5妹妹，深度為100妹妹，這樣既可能使錨固膠與錨桿短缺打仗又可能節(jié)約錨固膠的用量。

Steel panel with chemical anchor bolt has very stringent requirements on the diameter of drilling hole which is in the concrete. If the diameter of the drilling hole is too small, anchor adhesive doesn’t work. Generally the diameter of the drilling hole should be 4-5妹妹 bigger than the anchor bolt, and the depth should be 100妹妹, this not only can help the anchor adhesive make full contact with the anchor bolt, but also can save the much adhesive.

5

對(duì)于鉆孔的清理是一個(gè)******緊張的關(guān)鍵，孔內(nèi)粉塵對(duì)于錨固膠的浸染將起到******緊張的浸染，可能接管低壓氣泵的方式清理孔內(nèi)粉塵，也可能用毛刷加打氣筒的方式，運(yùn)用毛刷的直徑要以及鉆孔的直徑概況相同，用毛刷在孔內(nèi)往返推拉多少回將孔內(nèi)粉塵清理進(jìn)去后再用吹多少回，這樣重復(fù)多少回將孔內(nèi)的粉塵殘缺清理清潔。不能運(yùn)用水洗法來(lái)清理孔內(nèi)粉塵，因?yàn)殄^固膠以及水是不相溶的，混凝土的性子決定了在錨固膠的外表組成的介質(zhì)，影響錨固膠的錨固力。

Cleaning drilling hole is very important, because the dust inside will seriously affect the adhesive. It can be cleaned by high pressure pump; also can by brush with pump, the diameter of the brush should be similar as the hole. Sweep off the dust by brush and blow by pump for few times until clean thoroughly. No water for cleaning because the adhesive and water are incompatible.

6

向孔內(nèi)注入錨固膠要接管分次注入的方式，將錨固膠按要求的比例攪渾，使錨固膠凝聚光陰操作在30min內(nèi)，這樣能耐是有短缺的光陰將錨固膠注入孔內(nèi)。有的錨固膠比照粘稠，在向孔內(nèi)注入時(shí)簡(jiǎn)略產(chǎn)負(fù)氣泡，這樣就嚴(yán)正影響錨固膠的錨固品質(zhì)。

Applying the anchor adhesive into the hole should adopt the method of separate application, and the anchor adhesive should be mixed as required proportion, so that the solidification time of the anchor adhesive could be controlled in 30min, so as to have sufficient time to apply the anchor adhesive into the hole . Some of the anchor adhesive is comparatively sticky, it’s easy to generate bubble while is applying into holes , which will seriously influence anchoring quality of anchor adhesive.

7

將錨桿逐步推入孔內(nèi)，要防御錨固膠溢出造成浪費(fèi)，但錨桿外露40妹妹時(shí)停止向孔內(nèi)推錨桿，這時(shí)要將錨桿在孔內(nèi)順時(shí)針轉(zhuǎn)運(yùn)2~3周使錨固膠可能以及錨桿殘缺打仗。

Push the anchor bolt into the hole slowly in order to prevent the adhesive overflowing, however , when anchor bolt appear 40妹妹, it should be stopped to push into the hole ,at this time, we need to swing clockwise for 2 ~3 turns so that the adhesive can contact with the anchor bolt entirely.

8

錨桿在錨固膠里手動(dòng)3h后，少數(shù)錨固膠可能達(dá)到要求的強(qiáng)度，就能在錨桿上裝置埋件了。

Anchor bolt should be static in the anchor adhesive after 3 hours , most of the anchor adhesive is able to reach the required intensity so that can be installed embedded parts on the anchor bolt.
