Abstract
The utility model discloses an expansion joint structure of a cast-in-place reinforced concrete baffle. The structure comprises the reinforced concrete baffle and a reinforced concrete base, asphalt felts and bituminous hemp fiber. A groove is arranged on a short column part of the base, the free end of the cast-in-place reinforced concrete baffle is inserted into the reinforced concrete base in the groove, and gaps between the side face and end heads of the cast-in-place reinforced concrete baffle and the reinforced concrete base are separated by the bituminous hemp fiber. The asphalt felts are cushioned on the part where the lower part of the cast-in-place reinforced concrete baffle is contacted with the reinforced concrete base. The structure is mainly used in condition for arranging the expansion joint when length of the cast-in-place reinforced concrete baffle exceeds the regulated length in a standard. The method is convenience in construction and simple and reasonable, and the construction progress of the project is not affected.
Description
Technical field
The utility model relates to building field, is the structure at a kind of cast-in-situ steel reinforced concrete baffle plate shrinkage joint specifically.
Background technology
In industrial construction, usually can run into the situation that there is the big discrepancy in elevation in indoor and outdoor.The discrepancy in elevation is general when big uses retaining wall, and the discrepancy in elevation just is commonly used than a hour steel concrete baffle plate.Stipulate clearly in the standard that any structure all should arrange Temperature Joint after surpassing certain-length.For achieving the goal, way in the past normally adopts the ater-casting section construction.The ater-casting way of beam namely leaves 800-1000mm in the appropriate location of beam width range is fluid concrete not, only reinforcing bar is arranged usually, after treating the intact 28d of this scope both sides concreting, concrete surface cutter hair with both sides, water again than the higher leveled concrete of design strength, and at the place, ater-casting an amount of reinforcing rib need be set.Above-mentioned conventional way construction is very complicated, and the engineering time is longer, influences construction speed.And complicated unexpectedly with the Temperature Joint cancellation of concrete baffle plate because of ater-casting construction in actual engineering, cause baffle plate Yin Wendu flexible and ftracture, thereby bring potential safety hazard to building.
Concrete baffle plate shrinkage joint way easy construction in the utility model does not influence construction speed, and can satisfy the design instructions for use fully.
Summary of the invention
Technical problem to be solved in the utility model is: under the situation that does not influence programming, steel concrete baffle plate Temperature Joint is set rationally.Easy construction can satisfy the design instructions for use fully.
For addressing the above problem, the utility model is achieved in that
A kind of cast-in-situ steel reinforced concrete baffle plate expanded joint structure comprises the cast-in-situ steel reinforced concrete baffle plate, reinforced concrete foundation, pitch flax silk, asphalt felt; Short column on the basis partly arranges groove, and the free end of cast-in-situ steel reinforced concrete baffle plate is inserted on the reinforced concrete foundation in the described groove, and the slit between cast-in-situ steel reinforced concrete baffle plate side, termination and the reinforced concrete foundation separates with the pitch flax silk; The part pad asphalt felt that cast-in-situ steel reinforced concrete baffle plate bottom contacts with reinforced concrete foundation.
Gap width between cast-in-situ steel reinforced concrete baffle plate side, termination and the reinforced concrete foundation is 40-60mm.
Advantage of the present utility model and effect are as follows:
Owing to adopted such scheme, make the Temperature Joint easy construction of cast-in-situ steel reinforced concrete baffle plate, advantages of simple, and do not influence construction speed.
Description of drawings
Fig. 1 is plan view of the present invention
Fig. 2 is Figure 1A-A sectional drawing
1. steel concrete baffle plates among the figure, 2. reinforced concrete foundation,
3. pitch flax silk, 4. asphalt felt, 5. groove.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the utility model comprises cast-in-situ steel reinforced concrete baffle plate 1, reinforced concrete foundation 2, pitch flax silk 3, asphalt felt 4, groove 5; Short column on the basis partly arranges groove 5, the free end of cast-in-situ steel reinforced concrete baffle plate 1 is inserted on the reinforced concrete foundation 2 in the described groove 5, and slit L1, L2 between cast-in-situ steel reinforced concrete baffle plate 1 side, termination and the reinforced concrete foundation 2 separate with pitch flax silk 3; The part pad asphalt felt 4 that cast-in-situ steel reinforced concrete baffle plate 1 bottom contacts with reinforced concrete foundation 2.
Slit L1 between cast-in-situ steel reinforced concrete baffle plate 1 side, termination and the reinforced concrete foundation 2, L2 width are 40-60mm.
Job practices of the present utility model: according to the engineering actual conditions, in position select one to stride, the reinforced concrete foundation that cast-in-situ steel reinforced concrete baffle plate one end is joined with it is not put in order and is watered, and only is shelved on the basis.The short column of reinforced concrete foundation is partly made groove with the method for choosing ear, the free end of cast-in-situ steel reinforced concrete baffle plate is inserted in the groove, and leave the slit of 40-60mm between the reinforced concrete foundation.Slit between cast-in-situ steel reinforced concrete baffle plate side, termination and the reinforced concrete foundation separates with the pitch flax silk; The part pad asphalt felt that cast-in-situ steel reinforced concrete baffle plate baffle plate bottom contacts with reinforced concrete foundation.The size of asphalt felt should be determined according to the contact area of cast-in-situ steel reinforced concrete baffle plate and reinforced concrete foundation.The reinforced concrete foundation short column choose ear length degree L, the width D of width B and groove should be according to the thickness of cast-in-situ steel reinforced concrete baffle plate and highly definite, and the L value generally is not less than 250mm, and B should calculate according to the stressing conditions of baffle plate and determine, and be not less than 150mm, D is that baffle plate thickness b adds 2 * L1.Among the figure, H is that basis end absolute altitude is to the distance between basic top mark height.
