Detailed Description

As shown in fig. 1 and 2, the utility model relates to a large-scale equipment basis wood system embedded bolt cover that typical embodiment provided, including plank sheathing 1, square timber keel 2, cross skeleton 3 and outsourcing benzene board 4.

As shown in fig. 3, four wood formworks 1 are spliced into a bolt sleeve main body with a hollow cuboid structure. Preferably, as shown in fig. 3, the wood formworks 1 are assembled in a clockwise overlapping manner, where the clockwise overlapping manner means that an inner side surface of a first end of any one of the wood formworks 1 is connected to an end surface of an adjacent one of the wood formworks 1, and an end surface of a second end of the wood formwork 1 is connected to an inner side surface of one end of another adjacent one of the wood formworks 1. Compared with the common same-direction lap joint assembly mode (figure 4), the clockwise lap joint has the advantages of firm disassembly and capability of reducing the probability of damage of the bolt sleeve during disassembly.

As shown in fig. 5, the upper parts of the two opposite wood formworks 1 are correspondingly provided with a demolding hole 5.

The four corners of bolt cover main part are along vertical direction fixed square timber joist 2 respectively, and the cross skeleton 3 that forms is pieced together by two wood-rubber compound template crosses is inserted in bolt cover main part middle part, and four tip of cross skeleton support respectively in the medial surface of bolt cover main part, fix at bolt cover central point. The bolt sleeve body is internally reinforced by square wood keels 2, and a wood plate cross-shaped framework 3 is embedded in the middle of the bolt sleeve body, so that the whole bolt sleeve is not deformed under the extrusion of concrete, and cannot lose shape under external force during dismantling.

The upper and lower open end of bolt housing main part is provided with lamina tecti 6 and end cover 7 respectively, and lamina tecti 6 and end cover 7 are equallyd divide and are respectively embedded in the upper and lower open end of bolt housing main part, make wholly more firm, and guarantee when demolising that the end cover can not suffer to destroy and keep somewhere downtheholely. The top cover plate 6 and the bottom cover plate 7 are respectively provided with an operation hole 8 (figure 6) of a bonding belt in the middle, the operation hole 8 of the bonding belt is used for integrally fixing the bolt sleeve on a coating frame of the bonding belt, the coating of the bonding belt is convenient through rotating the bolt sleeve, and the concrete method is as follows: and (3) a central shaft of the cladding frame penetrates through the bonding belt operating holes reserved in the centers of the top cover plate and the bottom cover plate of the bolt sleeve, the bolt sleeve is fixed on the bonding belt cladding frame, and then the bolt sleeve is synchronously rotated along with the winding of the bonding belt, so that the bonding belt cladding construction and quality control are achieved.

The outer polystyrene board 4 is coated outside the bolt sleeve main body. The polystyrene board is added on the outer side of the wood template 1, so that the mold can be integrally pulled out. The plastic adhesive tape is wrapped on the outer side of the benzene plate, so that the benzene plate can be conveniently and integrally pulled out without pollution.

Examples

Manufacturing a bolt sleeve:

and (3) carrying out batch processing production on the equipment foundation bolt sleeves according to the number and turnover times of the equipment foundations poured each time, and selecting the wood-rubber die plate with smooth surface, good quality and excellent quality.

The wood template 1 is cut to be calculated according to the size, so that the mold is convenient to remove, the specification of the mold core is slightly larger than the design size of the reserved hole, and the lower part of the mold core is small and the upper part is large, 1: 10 tremble the degree and be favorable to the mould to extract, and bolt housing outsourcing 1cm benzene board, the size of outsourcing benzene board need be deducted when the mould cuts to guarantee to reserve the design size of entrance to a cave after the form removal, about the bolt housing upper shed elevation will be higher than bolt hole top elevation 25cm, the box body is demolishd in the perforation of being convenient for.

And the middle cross-shaped framework 3 is customized, a wood-rubber die assembly plate is adopted to be cut into a wedge-shaped square plate which is slightly smaller than the embedded top cover plate by 1cm, a groove is reserved in the middle of the wedge-shaped square plate, and the two die plates are spliced in a cross manner. The polystyrene board is a white foam board with the thickness of 1cm, and has the characteristics of good toughness, light weight, economy, durability and convenience in cutting, the size of the wood-rubber composite template which is pressed down during cutting is taken as a model, the size of an upper opening is controlled to be about 5cm of the elevation of the top of a bolt hole, slurry can be prevented from being poured in, and the polystyrene board is convenient to dismantle.

The centers of the top cover plate 6 and the bottom cover plate 7 are respectively penetrated with phi 8 round holes, inserted into the cladding frame, well controlled and fully adhered with the adhesive tape.

The bolt sleeve mounting method comprises the following steps:

the bolt sleeve is installed and positioned on the equipment foundation, the cup opening is provided with a hole reinforcing rib, double rows of reinforcing ribs are used for binding and reinforcing connection, and a welding process is forbidden to be adopted so as to prevent welding slag from burning and leaking the polystyrene board and influencing later-stage mould removal.

Pouring the concrete twice, and rechecking the central line, the elevation and the verticality of the bolt sleeve before pouring the equipment foundation so as to ensure that the central line of the bolt sleeve is positioned correctly; and after the concrete is accurate, pouring the upper foundation concrete, and rechecking the elevation and the verticality of the embedded bolt sleeve before the initial setting of the concrete so as to ensure the embedding quality of the embedded bolt sleeve.

The bolt sleeve dismounting method comprises the following steps:

in order to ensure that the embedded bolt sleeve is smoothly pulled out, the embedded bolt sleeve is detached after the initial setting of the concrete and before the final setting of the concrete.

Drilling a mold removing hole 5 with the diameter phi 12 at the exposed part of the bolt sleeve, transversely penetrating a phi 12 steel bar, and exposing 10cm at two sides for sleeving a lifting lug.

Preparing two to three kinds of square timbers with different lengths as fulcrums, inserting short steel bars welded on the front section of the scaffold tube into the lifting lugs to serve as crow bars, and sequentially using the square timbers with different lengths as the fulcrums to pull out the bolt sleeves by adopting a lever principle. If the lateral pressure of concrete is too large, the lever principle dismantling method cannot be implemented, a standby scheme can be adopted, a steel pipe hanger is made, a manual chain block is hung on the bolt sleeve in a vertical mode, and the bolt sleeve is dismantled.

Demolish bolt sleeve back, the downthehole surplus benzene board of bolt takes the crow bar to become flexible all around the benzene board, owing to take the sticky tape to fully glue, the benzene board after becoming flexible can wholly be extracted, and the benzene board sediment that the sporadic dropped can float the downthehole benzene board sediment of watering of bolt, and the manual work is clear away can, if there is the benzene board sediment that can't clear away in the bottom, usable rosin water instils into and takes place chemical reaction with the benzene board, clears away the benzene board sediment.

And the dismantled benzene plates are collectively stacked to an unrecyclable waste stacking point, are recovered and processed by a local sanitation garbage truck before fixed-point orientation, and the dismantled bolt sleeves are collectively stacked, are hung to a processing area, are re-coated with the benzene plates and are used for installing the next batch of equipment foundations.
