Abstract
The invention relates to a construction method of prefabricating a clear water concrete stand plate, which aims at providing a construction method with stable connection and mounting. The construction method is characterized by comprising the following steps: a, at least one beam mounting hole matched with a transverse plate of the stand plate is arranged on a support beam of a stand, and the support beam is used for supporting two ends of the stand plate; b, the clear water concrete stand plate is prefabricated, and at least one plate mounting hole matched with the transverse plate of the stand plate is arranged at each end of a vertical plate of the stand plate; c, at least two embedded parts matched with the mounting hole are embedded at each end of the transverse plate of the stand plate; d, a connecting part is connected with the embedded parts, shrinking-free grouting materials are injected into the mounting hole, the prefabricating stand plate is hoisted on the support beam of the stand, and the connecting part is respectively inserted into the beam mounting hole and the plate mounting hole. The invention has the advantages that the stand plate is firmly arranged on the support beam, the connection between the stand plates is stable, and the pressures between the stand plate and the support beam as well as between the stand plates are greatly buffered.
Description
Technical field
The present invention relates to a kind of job practices of concrete member, specifically be a kind of job practices of prefabricating clear water concrete stand plate.
Background technology
Clear-water concrete can adopt cast-in-place or prefabricated two kinds of schemes.As adopt cast-in-situ clear-water concrete to see platen, complex process, and input is bigger, long in time limit, so should not adopt cast-in-place.Prefabricated fair-faced concrete sees that the platen surfacing is smooth, and physical dimension is regular, and color and luster is even, can realize batch production production, can directly use after the lifting.But present prefabricating clear water concrete stand plate construction, because of the precast stand slab model various, the construction profile complexity, installation difficulty is big, and construction quality is not easy to ensure, the subject matter that exists is exactly: after seeing that platen is installed on the brace summer, because of non-one cast, the time one is of a specified duration, sees between platen and the brace summer easily loosening insecure, influence grandstand and use, and dangerous.On the other hand, upper and lower adjacent very difficult solution of connectivity problem of seeing between the platen.According to former design, see that platen connects the employing pre-embedded steel slab, and when mounted adjacent two pre-embedded steel slabs of seeing platen welded that finish the connection of seeing platen, the easy off normal of this kind connected mode steel plate causes structure to connect defective.After analyzing former design after deliberation, we will be welded to connect makes the bolt connection into, sees the platen purpose of connecting thereby reach.
Summary of the invention
The object of the invention is to provide a kind of energy will see that platen firmly is installed on the brace summer, sees the firm job practices of connection between the platen.
The objective of the invention is to adopt following technical proposals to realize: the job practices of prefabricating clear water concrete stand plate may further comprise the steps:
A, see in the support of grandstand be provided with on the brace summer at platen two ends at least 1 with the beam installing hole of seeing that the platen transverse slat is adaptive;
B, prefabricating clear water concrete stand plate are being seen platen riser two ends, at least 1 of every end setting and the plate installing hole of seeing that the platen transverse slat is adaptive;
C, seeing platen transverse slat two ends, pre-buried at least 2 built-in fittings adaptive of every end with installing hole;
D, connector is connected with built-in fitting, perfusion in the installing hole is not had the slurry of contraction, precast stand slab is lifted on the grandstand brace summer, connector inserts beam, plate installing hole respectively.
Beam buffering bearing also is set on brace summer among the step a.
Upper and lower seeing plate buffering bearing is set between the platen joint face.
Described buffering bearing is a neoprene bearing.
Described built-in fitting is an embedded nut.
Described connector is a bolt.
The nothing of perfusion contraction slurry is that C60 does not have the contraction slurry in the described installing hole of step c.
The invention has the beneficial effects as follows: because the setting of bolt, and bolt inserts perfusion and do not have the installing hole that shrinks slurry, will see that platen firmly is installed on the brace summer, overcome prior art and seen that platen installs unsteady problem; See to connect between the platen and reach firm effect equally.The setting of buffering bearing has cushioned greatly and has seen when platen uses the pressure of brace summer and see pressure between the platen, makes and sees platen and the more durable use of brace summer, and be convenient to see that platen firmly installs.
Description of drawings
Fig. 1 sees the platen scheme of installation for the present invention;
Wherein, 1, see platen, 2, brace summer, 3, built-in fitting, 4, connector, 5, the beam installing hole, 6, the plate installing hole, 7, beam buffering bearing, 8, plate buffering bearing.
The specific embodiment
As shown in the figure, the job practices of prefabricating clear water concrete stand plate may further comprise the steps:
A, see in the support of grandstand be provided with on the brace summer 2 at platen 1 two ends 1 with the beam installing hole 5 of seeing that platen 1 transverse slat is adaptive; Beam buffering bearing 7 also is set above the brace summer 2, and beam buffering bearing 7 is a neoprene bearing.
B, prefabricating clear water concrete stand plate are being seen platen 1 riser two ends, every end be provided with 1 with the plate installing hole 6 of seeing that the platen transverse slat is adaptive;
C, seeing platen 1 transverse slat two ends, every end pre-buried 2 with beam installing hole 5, the adaptive respectively built-in fitting 3 of plate installing hole 6, built-in fitting 3 is an embedded nut.；
D, connector 4 is connected with built-in fitting 3, connector 4 is a bolt, and bolt screws in nut can conveniently finish the two connection; Perfusion C60 in the installing hole is not had the contraction slurry, guarantee that promptly smooth and easy the assurance again of bolt hand-hole is connected firmly; Precast stand slab 1 is lifted on the grandstand brace summer 2, and connector 4 inserts beam installing hole 5, plate installing hole 6 respectively.Simultaneously, upper and lower seeing plate buffering bearing 8 is set between the platen joint face, plate buffering bearing 8 is a neoprene bearing.。
After slurry solidifies, see that platen and brace summer finish solid and reliable connection, adjacent seeing realized between the platen firm the connection.
This improvement has been compared following advantage with former design:
1, reduce difficulty of construction Optimizing construction technology:
The dimensional discrepancy that causes when adopting this kind method of attachment effectively to avoid pre-embedded steel slab is with multiple pre-Bury size and become two kinds of pre-buried sizes, optimized construction technology.
2, simple to operate, save the construction period:
The unified size for connection of seeing platen had not only facilitated but also had made connection standard to production and construction had been installed, and carried The high speed of application of producing becomes the welding in the design and installation process into bolt and connects and reduced by a procedure Accelerated installation progress, improved the quality of connection of seeing platen and ensured safe construction.
3, improve quality of connection:
With the steel plate in the former design not fixedly embedded part make fixedly embedded part of bolt into, avoided the steel plate embedded part displacement to make What become does not connect, and has avoided snapping the security-hidden trouble that causes yet, and has reached the two rich of quality and safety Receive.
4, reduced construction costs:
Use this improvement, make the higher steel plate of cost into lower-cost reinforcing bar, both reduced working procedure, Reduce largely again construction costs, saved cost.
