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，臨時披露在空氣中，抵抗侵蝕的能耐也較差。縱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質變換。另一種錨固埋件的方式便是接管化學螺栓錨固埋件，用飽以及樹脂將錨桿以及混凝土堅貞粘接在一起，同時樹脂也起到呵護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

化學螺栓個別接管的錨固膠有兩大規范，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定的光陰內達到預約的強度。

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.

修筑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

清理下層，定位放線，在錨固點的需要位置將混凝土的外表清理平展，在艱深粘土燒結磚上施工化學螺栓，其強度將著落，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)，如在非凡狀態下，若需要將混凝土內的鋼筋切斷，必須經由無關結構工程師的應承方可施工。

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

化學錨固埋件對于在混凝土上的鉆孔直徑要求也是******嚴厲，鉆孔的直徑過小起不到錨固膠應該有的浸染。個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

對于鉆孔的清理是一個******緊張的關鍵，孔內粉塵對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粉塵，也可能用毛刷加打氣筒的方式，運用毛刷的直徑要以及鉆孔的直徑概況相同，用毛刷在孔內往返推拉多少回將孔內粉塵清理進去后再用吹多少回，這樣重復多少回將孔內的粉塵殘缺清理清潔。不能運用水洗法來清理孔內粉塵，因為錨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，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，這樣能耐是有短缺的光陰將錨固膠注入孔內。有的錨固膠比照粘稠，在向孔內注入時簡略產負氣泡，這樣就嚴正影響錨固膠的錨固品質。

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，要防御錨固膠溢出造成浪費，但錨桿外露40妹妹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3h后，少數錨固膠可能達到要求的強度，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.
