化學錨栓連接介紹

埋件錨固方法

The anchoring of embedded part

埋件的錨固有兩種方法，一種是用膨脹螺栓錨固埋件，這樣漲殼式錨桿的錨固力受到客觀條件的約束較大，長期暴露在空氣中，抵抗腐蝕的能力也較差。即使在相同混凝土上採用相同的膨脹螺栓，錨固力也有很大的變化，這主要是由工人的施工操作原因造成的質量變化。另一種錨固埋件的方法就是採用化學螺栓錨固埋件，用飽和樹脂將錨桿和混凝土牢固粘接在一起，同時樹脂也起到保護錨桿不受腐蝕的作用。

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

化學螺栓通常採用的錨固膠有兩大類型，一種為等量混合型；另外一種為快乾劑型，即在錨固膠中加上一定比例催化劑使錨固膠能夠在規定的時間內達到預定的強度。

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.

建築化學螺栓錨固埋件的施工工藝

The construction technology of steel panel anchoring by chemical anchor bolt

1

清理基層，定位放線，在錨固點的需要位置將混凝土的表面清理平整，在普通黏土燒結磚上施工化學螺栓，其強度將降低，能夠使埋件的平整。

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

鑽孔的位置距混凝土的邊緣5D(D為錨桿的直徑)，如在特殊情況下，若需要將混凝土內的鋼筋割斷，必須經過有關結構工程師的允許方可施工。

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

鑽孔要和混凝土牆面垂直，使錨固栓和埋鐵垂直。

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

4

化學錨固埋件對在混凝土上的鑽孔直徑要求也是非常嚴格，鑽孔的直徑過小起不到錨固膠應該有的作用。通常鑽孔的直徑要比錨桿的直徑大4~5mm，深度為100mm，這樣既能夠使錨固膠與錨桿充分接觸又能夠節約錨固膠的用量。

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 4-5mm bigger than the anchor bolt, and the depth should be 100mm, this not only can help the anchor adhesive make full contact with the anchor bolt, but also can save the much adhesive.

對鑽孔的清理是一個非常重要的環節，孔內粉塵對錨固膠的作用將起到非常重要的作用，可以採用高壓氣泵的方法清理孔內粉塵，也可以用毛刷加打氣筒的方法，使用毛刷的直徑要和鑽孔的直徑大體相同，用毛刷在孔內來回推拉幾次將孔內粉塵清理出來後再用吹幾次，這樣反覆幾次將孔內的粉塵徹底清理乾淨。不能使用水洗法來清理孔內粉塵，因為錨固膠和水是不相溶的，混凝土的性質決定了在錨固膠的表面形成的介質，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

向孔內注入錨固膠要採用分次注入的方法，將錨固膠按要求的比例混合，使錨固膠凝固時間控制在30min內，這樣才能是有充分的時間將錨固膠注入孔內。有的錨固膠比較黏稠，在向孔內注入時容易產生氣泡，這樣就嚴重影響錨固膠的錨固質量。

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

將錨桿慢慢推入孔內，要防止錨固膠溢出造成浪費，但錨桿外露40mm時停止向孔內推錨桿，這時要將錨桿在孔內順時針轉運2~3周使錨固膠能夠和錨桿完全接觸。

Push the anchor bolt into the hole slowly in order to prevent the adhesive overflowing, however , when anchor bolt appear 40mm, 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

錨桿在錨固膠內靜止3h後，多數錨固膠能夠達到要求的強度，就可以在錨桿上安裝埋件了。

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.
