Description

Combined type prefabricated section curb

Technical field the utility model relates to a curb, concretely relates to combined type prefabricated section curb.

In northern severe cold areas such as inner Mongolia and the like, the conventional concrete precast block as a curb is extremely easy to be corroded by a snow-melting agent and the like, and meanwhile, the conventional concrete precast block is not processed and maintained in place. The long-term use of the utility model will lose the luster, and the damage such as loosening, threshing and the like often occurs, the strength is reduced and the utility model is not beautiful. But the concrete precast block can be poured into the curb stone with any shape, and the construction is convenient and the application is very wide.

The invention discloses a composite precast block kerb, which is made of durable material (such as PE and other high polymer materials) as an outer layer and is also a mould, and is formed by pouring and vibrating cement concrete in the mould. The utility model discloses a both can remain the workability of original cement concrete prefabricated section, can overcome the poor shortcoming of its durability through outsourcing macromolecular material simultaneously.

The technical scheme of the utility model as follows:

the utility model provides a combined type prefabricated section curb, this prefabricated section is by outer layer, cement concrete, and PVC or PE hollow tube are constituteed, outer while also is the mould, pours the compound prefabricated section curb of formation of vibrating with cement concrete in the mould, and all corners of prefabricated section are the chamfer, and the outer inboard vertical bulge that has, outer bottom have outside vertical bulge, there is PVC or PE hollow tube in the prefabricated section.

The PVC or PE hollow pipe is used for longitudinally connecting the kerbs through the connecting piece.

The connecting piece includes the tenon, and the connecting piece is vertical wide 1cm, and other overall dimension are the same with prefabricated section skin size, and the tenon is pegged graft with the hollow tube, through the PVC or the PE hollow tube in the tenon connection curb.

The outer layer is made of durable material.

The durable material is a PE high polymer material.

The length of the composite precast block kerb is 49 cm.

The utility model has the advantages that: the advantages are that: 1. the processing is convenient, the use of a die is reduced, and the strength is high; 2. the appearance is beautiful, the cleaning is convenient, and the durability is good; 3. the maintenance and pointing are avoided, and the saline-alkali corrosion is avoided; 4. the longitudinal connection can be realized, the smoothness and the straightness are good, and the overall strength and the stability are improved; 5. the bonding part of the water-based paint and the pavement has good water tightness, and the service life of the pavement can be prolonged; 6. the outer layer can be made into various colors according to the requirement.

FIG. 2 is a left side view of the composite curb;

FIG. 3 is a top view of the composite curb;

FIG. 4 is a composite kerb assembly view;

FIG. 5 is a front view of the connector;

FIG. 6 is a left side view of the connector;

FIG. 7 is a top view of the connector;

in the figure 1, an outer layer of PE high polymer material; 2. PVC or PE hollow pipes; 3. cement concrete; 4. an inboard longitudinal projection; 5. an outer longitudinal projection; 6. 2cm of mortar; 7. a connecting member; 8. circular table type tenon

The concrete embodiment is a composite curb precast block, which is made by casting and vibrating an outer layer 1 of PE high polymer material and a mould in the mould, and is formed by casting and vibrating cement concrete 3 in the mould. All corners of the precast block are chamfers, and the inner side longitudinal bulge 4 is arranged in the precast block, so that the precast block can be conveniently combined with the cement concrete 3 into a whole, and the strength of the outer layer can be effectively improved; the bottom of the precast block is provided with an outer longitudinal bulge 5 which is convenient to stabilize with mortar and increases the strength of the outer layer; 2 PVC or PE hollow pipes 2 are arranged in the prefabricated blocks, and longitudinal connection between the kerbstones is facilitated through connecting pieces 7; the connecting piece 7 comprises a circular table type tenon 8, the longitudinal width of the connecting piece 7 is 1cm, the sizes of other appearance sizes and the sizes of the prefabricated blocks are the same, the circular table type tenon 8 is connected with the PVC or PE hollow pipe 2 in an inserting mode, and the circular table type tenon 8 is connected with the PVC or PE hollow pipe 2 in the curb stone. As shown in particular in fig. 6. The length of the composite curb precast block is 49cm, and the height and the width of the composite curb precast block are determined according to position requirements. The longitudinal combination layout is shown in fig. 4.
