Abstract

The utility model discloses a template structure for concrete placement, especially a template structure for tower-silo reinforcement construction, which aims at the prior deficiency. The template structure for tower-silo reinforcement construction with convenient construction, comprises a steel template (1) arranged along the cycle direction of a primary silo wall (3), a casting cavity formed bythe steel template (1) and the primary silo wall (3) and a tie rod (8) with one end fixed on the primary silo wall (3), wherein the steel template (1) is fixed by another end of the tie rod. The construction is convenient and the steel template is prevented from turn over outwards and the connection between the primary silo wall and a reinforcement layer is reinforced and the template structure issuitable for reinforcement construction of the columnar structure walls such as tower-silo.

Description

The formwork structure that is used for the tower silo strengthening construction
Technical field
The utility model relates to a kind of formwork structure of concrete pouring, especially a kind of formwork structure that is used for the tower silo strengthening construction.
Background technology
In the industrial construction work progress, usually adopt the reinforced concrete cylinder storehouse as the place of depositing ore or coal material temporarily, but owing to be temporary building, the design of tower silo, construction are not very perfect, situations such as bulkhead cracking in use often occur, just need carry out strengthening construction tower silo in order to keep the safety in production.
At present, the common employing of reinforcing increases one deck steel bar concrete reinforcement layer and finishes outside former bulkhead, the formwork structure of strengthening construction adopts usually to be installed steel form and steel form is fixed the formation stable structure with steel pipe scaffold and iron wire outside the reinforcing cage of back-up coat.But this formwork structure, the steel pipe reinforcement means is loaded down with trivial details, and labor strength is big, and when fluid concrete, steel form is outwards rollover easily.
The utility model content
In order to overcome existing deficiency, technical problem to be solved in the utility model provides a kind of formwork structure that is used for the tower silo strengthening construction of easy construction.
The technical scheme that its technical problem that solves the utility model adopts is: the formwork structure that is used for the tower silo strengthening construction, comprise the steel form that circumferentially is provided with along former bulkhead, surround formation cast chamber by steel form and former bulkhead, comprise that an end is fixed on the pull bar on the former bulkhead, steel form is fixing by the pull bar other end.
The beneficial effects of the utility model are: pour into a mould chamber, easy construction by pull bar tension and formation between steel form and the former bulkhead.And after when cast and cast, outwards turn on one's side because the pulling force of pull bar has prevented steel form, the existence of pull bar has simultaneously also strengthened being connected of former bulkhead and back-up coat.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the formwork structure that is used for the tower silo strengthening construction of the present utility model comprises the steel form 1 that circumferentially is provided with along former bulkhead 3, surrounds with former bulkhead 3 by steel form 1 and forms the cast chamber, comprise that an end is fixed on the pull bar 8 on the former bulkhead 3, steel form 1 is fixing by pull bar 8 other ends.
Concrete, the stirrup 5 of described pull bar 8 by being arranged on steel form 1 outside be steel form 1 fixedly, is fixed with butterfly card 6 on the pull bar 8, and described stirrup 5 is stuck between steel form 1 and the butterfly card 6.Install for convenience, the end that described pull bar 8 is provided with butterfly card 6 is provided with screw thread, and described butterfly card 6 is fixed on the pull bar 8 by clamp nut 7.
Certainly, described pull bar 8 also can be directly by the fixing steel form 1 of the stirrup 5 that is arranged on steel form 1 outside on it, and be fixed by welding on the pull bar 8, perhaps by the butterfly card 6 that is arranged on steel form 1 outside on it fixedly steel form 1, perhaps other structures such as barb, block.
In order to strengthen the fastening force of butterfly card 6, described butterfly card 6 is fixed on the pull bar 8 by the solid nut 7 of two-restriction.
Construction for convenience, and make things convenient for the recovery of pull bar 8 to use, described pull bar 8 is fixed on the former bulkhead 3 by the bar planting 4 of implanting former bulkhead 3.Pull bar 8 is connected with bar planting 4 by welding, because the existence of pull bar 8 and bar planting 4 mainly is in order to prevent to pour into a mould and cast back steel form 1 is outwards turned on one's side, and after the back-up coat moulding reinforcement by connection layer and former bulkhead 3, mainly bear pulling force, described pull bar 8 also can adopt form such as hook to form to be connected with bar planting 4.
For convenience carry out strengthening construction in real time, promptly need not empty tower silo and just carry out strengthening construction, described bar planting 4 is implanted by chemical adhesive fixed, and certain described bar planting 4 also can be adopted expansion bolt etc.After tower silo empties, also can adopt the form of through hole pull bar.
The reinforced concrete cylinder storehouse position of barrel crackle occurs generally in the middle part that is subjected to the horizontal force maximum, middle part section to stressed maximum carries out strength checking, requirement is equivalent to tower silo height 2/3rds at the former bulkhead 3 outsourcing one decks of tower silo, and thick is the thick back-up coat of former bulkhead 1/3rd two.
During construction,, determine bar planting 4 density by the pulling force checking computations that produce between new and old silo, by boring on former bulkhead 3, with chemical adhesive bar planting 4 is implanted in the former bulkhead 3, welding thread 8 in bar planting 4 outer ends is by reasonable disposition steel form 1, steel form 1 is placed along back-up coat, steel form 1 usefulness reinforcing bar is pushed down butterfly card 6 to stirrup 5 by pull bar 8 as stirrup 5, by clamp nut 7 bandings, compress steel form 1, form formwork structure.
Steel form 1 is finalized the design by stirrup 5 bandings, and surrounds formation cast chambeies with former bulkhead 3, and the reinforcing cage 2 of back-up coat is arranged in the cast chamber, and former bulkhead 3 and steel form 1 pass through stirrup 5 and pull bar 8 and bar planting 4 tensions, easy construction.And after when cast and cast, outwards turn on one's side because the pulling force of pull bar 8 and bar planting 4 has prevented steel form 1, the existence of while pull bar 8 and bar planting 4 has also strengthened being connected of former bulkhead 3 and back-up coat.Formwork structure carries out concrete pouring by inspecting for acceptance.
