埋件的锚固有两种方法，一种是用膨胀螺栓锚固埋件，这样涨壳式锚杆的锚固力受到客观条件的约束较大，长期暴露在空气中，抵抗腐蚀的能力也较差。即使在相同混凝土上采用相同的膨胀螺栓，锚固力也有很大的变化，这主要是由工人的施工操作原因造成的质量变化。另一种锚固埋件的方法就是采用化学螺栓锚固埋件，用饱和树脂将锚杆和混凝土牢固粘接在一起，同时树脂也起到保护锚杆不受腐蚀的作用。

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.

化学螺栓通常采用的锚固胶有两大类型，一种为等量混合型；另外一种为快干剂型，即在锚固胶中加上一定比例催化剂使锚固胶能够在规定的时间内达到预定的强度。

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.

清理基层，定位放线，在锚固点的需要位置将混凝土的表面清理平整，在普通黏土烧结砖上施工化学螺栓，其强度将降低，能够使埋件的平整。

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.

钻孔的位置距混凝土的边缘5D(D为锚杆的直径)，如在特殊情况下，若需要将混凝土内的钢筋割断，必须经过有关结构工程师的允许方可施工。

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.

钻孔要和混凝土墙面垂直，使锚固栓和埋铁垂直。

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

化学锚固埋件对在混凝土上的钻孔直径要求也是非常严格，钻孔的直径过小起不到锚固胶应该有的作用。通常钻孔的直径要比锚杆的直径大4~5mm，深度为100mm，这样既能够使锚固胶与锚杆充分接触又能够节约锚固胶的用量。

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.

对钻孔的清理是一个非常重要的环节，孔内粉尘对锚固胶的作用将起到非常重要的作用，可以采用高压气泵的方法清理孔内粉尘，也可以用毛刷加打气筒的方法，使用毛刷的直径要和钻孔的直径大体相同，用毛刷在孔内来回推拉几次将孔内粉尘清理出来后再用吹几次，这样反复几次将孔内的粉尘彻底清理干净。不能使用水洗法来清理孔内粉尘，因为锚固胶和水是不相溶的，混凝土的性质决定了在锚固胶的表面形成的介质，影响锚固胶的锚固力。

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.

向孔内注入锚固胶要采用分次注入的方法，将锚固胶按要求的比例混合，使锚固胶凝固时间控制在30min内，这样才能是有充分的时间将锚固胶注入孔内。有的锚固胶比较黏稠，在向孔内注入时容易产生气泡，这样就严重影响锚固胶的锚固质量。

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.

将锚杆慢慢推入孔内，要防止锚固胶溢出造成浪费，但锚杆外露40mm时停止向孔内推锚杆，这时要将锚杆在孔内顺时针转运2~3周使锚固胶能够和锚杆完全接触。

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.

锚杆在锚固胶内静止3h后，多数锚固胶能够达到要求的强度，就可以在锚杆上安装埋件了。

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.
