Technical field
The utility model relates to a kind of base plate crack repairing structure, particularly a kind of basement reinforced concrete floor crack combined type preparing structure.Belong to building engineering field.
Background technology
The basement bottom board crack is Common Diseases in construction work, the main cause of its formation is reinforced concrete floor impact of being subjected to uneven settlement of foundation, difference variation, external loads and concrete self quality etc., in use due to the cracking, not only can have a strong impact on the normal use of basement, and the phenomenon such as consequent infiltration also can make the reinforcing bar of base plate interior produce corrosion, thereby cause the reduction of supporting capacity, durability and the impermeability of Reinforced Concrete Materials, therefore need in time take the crack repairing measure.
At present the repairing measures for the base plate crack mainly contains following several:
First method is grouting or joint filling patching, and way is directly will repair injecting cement paste to inject the crack it is played a role, and generally is applicable to the operating mode that remedial is repaired, and has advantages of reparation speed piece, cheap.Portland cement grouting is applicable to roomy crack, waterproof effectively, but bonding not ideal enough to the cracking part; Chemical grouting method can be used for wet environment, and can control time of setting, also can be used for very trickle crack, and shortcoming is that technological requirement is high, and intensity is low.Grouting or joint filling patching are repaired and are contacted often firmly not between injecting cement paste and original concrete floor, and further the carrying out of uncontrollable crack is therefore be unsuitable for the repairing in structural crack.
Secondly be reinforcement anchoring method, usually adopt in the time must repairing the tensile strength of main slight crack section.Way is in the boring of both sides, crack, imbeds at a certain distance reinforced steel, and fills out embedding with atresia shrinkage water mud.This method is repaired for structural crack has effect preferably, but waterproofing course for want of, water easily infiltrate repair structure inside, cause corrosion of steel bar and make concrete new crack occur because of alkali, can't guarantee the durability of structure, and the structure outward appearance is had considerable influence.
In sum, for solve the repair structure durability that existing crack recovery technique exists not enough, can't effectively resist the problem such as further carrying out of crack, be badly in need of at present a kind of continuation cracking that has certain barrier performance, also can effectively control the crack of invention, have the Novel bottom plate crack repairing structure of technical economic benefit preferably.
Summary of the invention
The purpose of this utility model is to fully utilize the advantage of grouting or grouting joint filling method and reinforcement anchoring method etc., by forming injecting cement paste at base plate bottom injection slurries, and waterproofing course, horizontal mesh reinforcement, tension rib etc. are set strengthen the durability of structures and load-carrying properties etc., invent a kind of have good barrier performance, and the Novel reinforced concrete basement bottom board crack repair structure that can control effectively that the continuation in crack ftractures.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
The composite repair structure in a kind of basement reinforced concrete floor crack is characterized in that opening along the base plate fractuer direction inverted trapezoidal groove of non-through base plate, and the base plate of inverted trapezoidal groove bottom forms the base plate leave strip, and the fluting place of base plate forms base plate reparation band; Connect the base plate leave strip in the bottom of inverted trapezoidal groove and open injected hole, and inject injecting cement paste by injected hole bottom base plate;
In bottom land and the sidewall perforate respectively of inverted trapezoidal groove, arrange tension rib in the hole; The inverted trapezoidal bottom land is built to repair and is with the bottom waterproofing course; The netted reinforcement of fixed level between the tension rib of inverted trapezoidal groove sidewall; Set gradually bar shaped slip casting reparation band on inverted trapezoidal groove inner bottom part waterproofing course, repair band top waterproofing course, base plate top repair layer.
The composite repair structure in aforesaid basement reinforced concrete floor crack is characterized in that described injecting cement paste is positioned at the part of base plate bottom, and its injecting cement paste reinforcing scope is more than or equal to inverted trapezoidal groove upper opening width.
The composite repair structure in aforesaid basement reinforced concrete floor crack, it is characterized in that repairing band bottom waterproofing course and reparation is the SBS modified bitumen with top waterproofing course waterproofing materials used; Base plate top repair layer adopts carbon fiber reinforced concrete.
The composite repair structure in aforesaid basement reinforced concrete floor crack is characterized in that the reinforced mesh that the horizontal mesh reinforcement adopts high tensile steel wire grid or welding colligation to form.
The utlity model has following characteristics and beneficial effect:
(1) the base plate leave strip has strengthened base plate and has repaired the cooperative bearing performance of being with, offer injected hole and enter injecting cement paste to the base plate rising pouring on the base plate leave strip, can strengthen the holistic resistant behavior of base plate bottom, thereby solve that traditional restorative procedure effects on surface is repaired and can't carry out to the base plate bottom drawback of consolidation process.
(2) be provided with tension rib between bar shaped slip casting reparation band and both sides base plate, base plate leave strip, can strengthen the globality of repair structure, effectively prevent further carrying out of crack, be particularly useful for the repairing in structural crack.
(3) bar shaped slip casting reparation band bottom and top are provided with waterproofing course, can stop underground water or top water accumulation leaking to enter and repair band etc., can effectively avoid the appearance of the diseases such as base plate leakage, thereby strengthen the durability of repair structure.
