Abstract
The utility model relates to a concrete cover cushion block and aims to provide the concrete cover cushion block to improve construction efficiency and ensure the thickness of a concrete cover in a project. The utility model adopts the technical scheme that the concrete cover cushion block is provided with a columnar cushion block, and is characterized in that a plane surface is formed at one end of the cushion block; U-shaped grooves staggered having different depths and arranged in a crossed manner are formed in the plane surface; a wire is pre-buried in the cushion block; two ends of the wire extend out of the end surface; and the other end of the cushion block adopts a streamline structure. The concrete cover cushion block is suitable for reinforced concrete works.
Description
Technical field
The utility model relates to a kind of cushion block, especially a kind of reinforced concrete protective layer cushion block.Be applicable to reinforced concrete works.
Background technology
Aspect China's building operations, adopt cement mortar to make cushion block at the construction field (site) usually, because condition is relatively poor; The cushion block size thickness of making etc. are very irregular; The thickness of topping in can not guaranteeing to construct, in time, has and reveals the muscle phenomenon and take place, and has influence on construction quality.In addition, do cushion block with the cement mortar scene, intensity is on the low side, and is cracked easily, can not guarantee the regular thickness of topping well equally, thereby influence construction quality.Be head it off; " Chinese utility model patent communique " discloses a kind of " reinforcing bar is used the concrete cover cushion block " by name; The patent No. is: " 01239974.4 " and a kind of by name " a kind of reinforcing bar use the concrete cover cushion block ", the patent No. is: the utility model patent technology of " 200410060258.7 ", and discovery in use has following deficiency: cushion block need be put on iron wire on being fixed on reinforcing bar the time in advance; Make troubles to colligation, waste man-hour; Cushion block is fixed in the cage of reinforcement of intersection, because the cross recess degree of depth of cushion block is the same, can not cooperates steadily, and then swing, thereby influence thickness of protection tier; Cushion block bottom is bigger with the template contact surface, and mud mobile bad causes the cushion block bottom to lack and starch or exposing surface, influences workmanship; Cushion block intensity is not high, and is cracked easily in colligation and work progress, directly influenced the thickness of reinforcement cover.
Summary of the invention
The technical problem that the utility model will solve is: the problem to above-mentioned existence, a kind of reinforced concrete protective layer cushion block is provided, and to improve efficiency of construction, guarantee the thickness of reinforced concrete protective layer in the engineering.
The technical scheme that the utility model adopted is: the reinforced concrete protective layer cushion block; Cushion block with column; It is characterized in that: said cushion block one end is the plane; Have the not U type groove of interlaced arrangement in the lump of the degree of depth on it, be embedded with iron wire in the cushion block and said end face is stretched out at the iron wire two ends, the other end of this cushion block is streamlined structure.
Described streamlined structure is smoothly transitted into three salient points of evenly arranging for the cylinder face of cylinder.
The iron wire that stretches out planar ends is 180 degree symmetric arrangement.
The beneficial effect of the utility model is: the utility model adopts the high strength cement manufacturing, has fundamentally solved strength problem.The U type groove of the two different degree of depth cooperates staggered reinforcing bar just on the cushion block end face, not only can not produce swing, also can not be subjected to displacement.The iron wire that is embedded in cushion block can be realized the quick colligation of cushion block location, has reduced the trouble of wearing iron wire.The cushion block bottom surface carries out the transition to three salient points by disc, not only can reduce the consumption of himself cement, has guaranteed the stability of its support, and in the concrete placement in later stage, cushion block is difficult for slippage.The bottom surface streamlined structure can increase the flow model of mortar, can make mortar fully fill up the cushion block bottom, has improved the surface quality of cast.
Description of drawings
Fig. 1 is the vertical view of the utility model.
Fig. 2 is the utility model U type groove end-view.
Fig. 3 is the sectional view of the utility model.
Fig. 4 is the utility model salient point end-view.
The specific embodiment
Like Fig. 1, shown in Figure 2, present embodiment is a concrete cover cushion block that has two perforations, and two U type grooves are the right-angled intersection layout.The main body of cushion block 1 is a cylinder, and cushion block 1 and reinforcing bar contact jaw have the right-angled intersection U type groove 1-2 of two different groove widths and groove depth, guarantees that staggered reinforcing bar can firmly be adjacent to.In the casting process of cushion block 1, U type groove place section (see figure 1) is stretched out at the two ends that are embedded with iron wire 2 and iron wire 2, has reduced the trouble of wearing iron wire, increases work efficiency.
The other end of cushion block 1 is a support end, and support end is streamlined structure and is smoothly transitted into three equally distributed salient point 1-1 (see figure 4)s by the face of cylinder of cylinder, guarantees the stability of its support, has improved the flowability of mortar in the construction.
Described cushion block 1 forms for the high strength cement cast, guarantees its intensity.
During construction, cushion block 1 is engaged on the staggered reinforced frame, notices that the thickness of reinforcing bar cooperates, cooperated directly to get final product with pre-buried iron wire 2 colligations.
Claims (3)
1. reinforced concrete protective layer cushion block; Cushion block (1) with column; It is characterized in that: said cushion block one end is the plane; Have the not U type groove (1-2) of interlaced arrangement in the lump of the degree of depth on it, be embedded with iron wire (2) and iron wire two ends in the cushion block and stretch out said end face, the other end of this cushion block (1) is streamlined structure.
