Description
Technical field
This utility model is related to underground engineering structure construction joint joint patching field, and more particularly, to a kind of construction joint stops
Water installations.
Background technology
During the main structure construction of underground station, because station is longer, consider from construction technology and construction speed, need main body
Structure is divided into some sections and individually constructs, then the problem arises, and two adjacent construction sections are suitable due to the priority of casting concrete
Sequence is different, leads to seam crossing concrete binding poor, easily causes structure leak.Currently generally adopt a kind of steel plate for sealing water (plating
Zinc steel plate thickness 3-5mm, wide 300mm about, length is certain modulus, and steel plate both sides tilt) construction joint is processed, construction step
Suddenly as follows：First, after completing agent structure plate face reinforcing bar (or wall steel bar) colligation, steel plate for sealing water is placed on plate face pars intermedia
Position, and fix, then carry out steel plate seam welds. temporarily；Secondly, using the fixing steel plate for sealing water of welding manner it is ensured that steel plate is put into
Half in structure；Then, after completing steel plate for sealing water fixation, adopt closing in net plugging construction to stitch in steel plate for sealing water both sides, and adopt
Welded reinforcement head is reinforced.After completing treatment of construction joints, casting concrete, after concrete initial set, blows reinforcing steel in time
Muscle, understands closing in net.But this mode yet suffers from many problems, such as：During steel plate for sealing water fixing using welded reinforcement, by
Unstable or artificial origin easily causes steel plate for sealing water burn-through in electric current, have a strong impact on stagnant water effect；Fixed using welded reinforcement
Steel plate for sealing water needs the point of welding more, and workload is big, and welding quality does not ensure；When construction joint is blocked using the net that closes up, receive
Mouth net is typically fixed using the reinforcing bar of fixing steel plate for sealing water, and when welding, the position of reinforcing bar and spacing are difficult to regular arrangement,
Result in the fixing effect of net that closes up poor, pour appropriate to the occasion spillage, be that subsequent construction brings unnecessary trouble.
Improve constantly with the requirement to construction quality for the people, the requirement to engineering for the construction unit is also increasingly harsher, such as
Where do not increase cost input or reduce plus cost input on the premise of, the seam stagnant water effect increasing substantially construction has been compeled
The eyebrows and eyelashes.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of construction joint antipriming, keeps away
Exempt from steel plate for sealing water by burn-through, decrease welding job amount, net construction of closing up is fast, and improves construction quality.
For achieving the above object, this utility model can be achieved by the following technical programs：
A kind of construction joint antipriming, including steel plate for sealing water, embeds two rows in described steel plate for sealing water longitudinal middle part equidistant
Nut, described nut is screwed into the screw rod of coupling, and the upper and lower surface of steel plate for sealing water is stretched out at the two ends of described screw rod respectively, positioned at institute
Closing in net is all inserted between the two row's screw rods stating steel plate for sealing water upper and lower surface.
Further, the distance between described two row's nuts are 20mm.
Further, the distance between adjacent described nut of same row is 500mm.
This utility model compared with prior art, has the advantages that：1st, the steel plate for sealing water after improving adopts bolt
It is connected, it is to avoid welding, is effectively guaranteed the construction quality of steel plate for sealing water, provide for succeeding body structurally waterproof and protect
Card；2nd, decrease number of welds, alleviate welding job and welding difficulty, improve construction speed；3rd, directly closing in net is put
Enter between screw rod, simple to operate, and closing in net construction quality is guaranteed, is that subsequent construction brings convenience, and improves construction speed, section
About cost.
Brief description
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the partial enlarged drawing of A in Fig. 1；
In figure：1- steel plate for sealing water, 2- nut, 3- screw rod, 4- closing in net.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, this utility model is further described：
As shown in Fig. 1～2, construction joint antipriming described in the utility model, including steel plate for sealing water 1, in steel plate for sealing water 1
Longitudinal middle part embeds (weld or paste it is ensured that steel plate for sealing water 1 is not damaged) equidistant nut of two rows 2, steel plate for sealing water 1 and nut 2
Can weld in process plants, and produce supporting screw rod 3, screw rod 3 diameter 8-12mm, depending on screw rod 3 length, screw rod 3 is long
Degree sets according to certain modulus, meets construction requirement.Supporting screw rod 3 is screwed on nut 2, the two ends of screw rod 3 are stretched out respectively
The upper and lower surface of steel plate for sealing water 1, thus can avoid steel plate for sealing water 1 by burn-through, also decrease welding job amount.Positioned at sealing
All insert closing in net 4 between two row's screw rods 3 of steel plate 1 upper and lower surface, with electric welding, screw rod 3 and structure both sides are just connect welding solid
Fixed, so not only closing in net 4 is constructed soon, and improves construction quality, also allows for subsequently dismantling.The work of wherein steel plate for sealing water 1
With being sealing, the effect of nut 2 is standing screw 3, and the effect of screw rod 3 is fixing closing in net 4, and the effect of closing in net 4 is closure
Construction joint.
Preferably, the distance between two row's nuts 2 are 20mm.
Preferably, the distance between adjacent nut 2 of same row is 500mm.
This utility model installation process is as follows：The first step, colligation good structure plate face (body of wall etc.) reinforcing bar；Second step, by applying
Work is stitched length and is prepared enough steel plate for sealing water 1, screw rod 3, closing in net 4 etc.；3rd step, it is screwed to steel plate for sealing water by sequential for screw rod
On 1 nut 2, and by between insertion two row's screw rod 3 orderly for closing in net 4 it is ensured that sealing；4th step, by mounted knot
Structure puts into the middle part of plate face at construction joint (body of wall etc.) reinforcing bar, and fixes it is ensured that there being enough overlap joints long between steel plate for sealing water 1 temporarily
Steel plate for sealing water 1 is welded to connect with DC welder, forbids steel plate for sealing water 1 burn-through by degree；5th step, had using DC welder suitable
The other end by screw rod 3 of sequence is connected with plate face (body of wall etc.) levels reinforcement welding, then looks for the steel bar end that gives up a bit to make a little diagonal braces
(one end is welded on screw rod 3, and one end is welded on the plate face reinforcing bar spilling outside construction joint), reinforces steel plate for sealing water 1 it is ensured that pouring
Build closing in net 4 during concrete mobile.
For a person skilled in the art, other can be made various corresponding according to above technical scheme and design
Change and deformation, and all these change and deformation all should belong to this utility model scope of the claims it
Interior.
